3 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
4 GNU TLS is used by default (if found).
6 yaz-ztest returns OPAC records if a client asks for OPAC.
8 Improved speed of MARC-8 encoding.
10 Added support for lossy and loss-less MARC-8 encoding.
12 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
14 Added new Windows Service wrapper (sc).
16 yaz-client's itemorder command may now send a file.
18 Fixed yaz-marcdump to allow the use of NS prefix for record element.
20 Added new function yaz_log_xml_errors.
22 Allow (but warn) unknown XML attributes in MARCXML parsing.
24 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
26 The UTF-8 to MARC-8 conversion now uses a different set of characters
27 for Greek symbols. Bug #2120.
31 Added yaz_daemon (daemon.h).
33 Fixed bug #2068: pkg-config trouble
35 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
39 Document --with-xml2 option.
41 Added OPAC XML XSD (etc/opacxml.xsd).
43 Allow glob mask for name attribute in retrieval element for the
44 generic frontend server's retrieval facility.
46 Changed yaz_poll_poll to return yaz_poll_except for all returned events
47 except POLLIN/POLLOUT.
49 Fixed error handling in cs_listen. Bug #2037.
53 Fixed version in yaz/yaz-version.h.
55 Fixed bug #2027: Crash when closing connection.
57 Changed configure so that ICU support is only enabled if only ICU
58 and Libxml2 is available (because the ICU chain is XML based).
62 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
63 is built. Only this DLL depends on the ICU runtime.
65 yaz-ziffy is no longer part of YAZ. It is distributed separately by
66 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
68 Changed license of CCL module to 'Revised BSD'. After consultation with
69 remaining members of the original EUROPAGATE consortium, we are re-issuing
70 the CCL module without a separate license. The software was developed by
71 Index Data as part of a research project. The special license was included
72 to help feed usage information back to the project consortium to support
73 project evaluation. At this time, the project consortium has long-since
74 disbanded, and the majority of the original principals have retired. At the
75 same time, we have significantly modified the software during the following
76 years, to the point where very practically no original code remains. To
77 simplify re-use of the software, we have contacted those members of the
78 consortium who could be reached, and agreed to re-issue the module as a
79 proper part of the YAZ package.
81 Tcl scripts uses /usr/bin/tclsh as preferred shell.
83 CQL closer to being version 1.2 compliant. CQL also allows free-form
84 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
87 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
88 bug could make Extended services handling crash in the ZOOM layer. This
89 bug was only present in YAZ 3.0.18.
93 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
96 yaz-marcdump reads and writes collection wrapped records.
98 Handle OPAC for record conversion module.
100 Fixes for ICU wrapper.
102 Allow ICU libs to be controlled with --with-icu .
104 --- 3.0.16 2007/11/12
106 Added yaz_poll which is a wrapper for select/poll. When poll is available
107 and non-buggy, it is used, by yaz_poll . This allows more than 1024
108 sockets to be in use.
110 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
111 functionality through an XML based configuration (ICU chain). This system
112 is useful for search facilities such as Pazpar2 and Zebra that needs to
113 perform tokenization of indexed material. The ICU code in a separate
114 library libyaz3_icu.a.
116 Added HTTP tunnel facility for COMSTACK, bug #1752.
117 This is a facility that allows a Web proxy, such as squid, to tunnel
118 Z39.50 traffic. This facility is "transparent" to must applications
119 using YAZ. It's enabled by using pseudo transport connect: followed by
120 the proxy address, followed by command, then follwed by he regular
121 "virtual" addresss. For example,
122 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
124 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
126 --- 3.0.14 2007/09/21
128 Fixed bad memory reference in ZOOM_record - cuased by member not being
129 initialized. This was a problem only in YAZ 3.0.12.
131 Fixed bug in conversion from MARC to XML: Non-XML characters in control
132 fields were not removed.
134 Changed the way C code is generated from codetables.xml. Made a MARC-8
135 conversion trie for each characterSet section rather than codeTable.
136 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
137 of codetables.xml from Larry Dixson, LOC. Bug #1464.
139 --- 3.0.12 2007/09/12
141 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
142 from ZOOM_record_error).
144 ZOOM C function ZOOM_record_get returns record schema for type="schema".
146 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
148 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
150 Better SRW-to-Bib-1 diagnostic mapping.
152 ZOOM C and yaz-client announces SRU version 1.2 by default.
154 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
157 Fixed in yaz_sru_decode to allow other version than 1.1.
159 --- 3.0.10 2007/08/22
161 Added support for SRU scan for ZOOM.
163 Added support for the use of the older versions or Extended Service
164 Update in ZOOM. To faciliate this, an option "updateVersion" may be
165 set to the version , 1=first, 2=second, 3=third. The third version is
166 what ZOOM C has used so far. And that, obviously, is the default.
168 Added support for CCL queries in Z39.50 queries sent to the GFS (and
169 therefore in Zebra and in SimpleServer-based applications). The new
170 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
171 qualifier file used to transform incoming CCL queries into Type-1 RPN,
172 which is passed into the back-end search callback function.
174 Added support for HTTP Basic authentication in clients: the SRU/W
175 codec encodes the username/password elements of the PDU structure
176 appropriately, and these may be set using the "user" and "password"
177 options in ZOOM-C applications (the same options that are used for
178 Z39.50 authentication).
182 Fixed bug #1208: SSL appears to be broken in ZOOM.
184 Fixed bug #1206: Libxml2 include path weirdness.
186 Added oid_name_to_dotstring.
188 Allow elementSetName to be specified for ZOOM C record update.
190 Allow waitAction to be specified for ZOOM C based for Extended Services.
192 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
193 syntax OID. Bug introduced in YAZ 3 series.
195 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
199 Fixed bug #1157: yaz-client does not read .yazclientrc from current
200 directory. yaz-client now reads commands from file given by option -f
201 if specified; then tries to read .yazclientrc in current directory.
202 Failing that, it reads .yazclientrc from user's home directory.
204 Added support for correlationInfo Note and ID for Record Update via
207 Added yaz-client command querycharset which specifies character set for
208 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
209 (termListAndStartPoint).
211 Charset ISO5428:1984 is an alias for ISO5428-1984.
213 Implemented a way to perform scan in a result set using Z39.50. This
214 is achieved by attaching the result set name in the characterInfo
215 (type InternationalString) of OtherInformation in the Scan Request PDU.
216 The result set is identified in the otherinformation by the new OID:
217 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
218 This allows for scan in result set and faceted search . Zebra did some
219 of this in the APT term using attribute type 8 and value being result
220 set. Using the OtherInformation approach for this is cleaner and easier
221 to work with in proxies and the like. This facility can be used in
222 yaz-client using new command setscan which takes a result set as first
223 argument, start position (APT) as second.
225 Changed decoding of SRU XML packed records to deal with servers that
226 have recordData with XML data with multiple root nodes. Also make
227 comparison for recordPacking case insensitive. Again, one server
228 returns "XML" where others return "xml".
230 For SRU responses allow Content-Type application/xml as well as text/xml.
234 Fixed bug in character set conversion of BER strings. Bug introduced
239 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
241 For OID class, use oid_class consistently.
243 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
246 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
247 character set for bibliographic information interchange". By Giannis Kosmas.
249 Added documentation on new OID API.
253 Changes to generic frontend server interface: added new member
254 'query_charset' for bend_initrequest structure. A backend init handler
255 should set this member to its native character set for query terms.
256 When defined, the frontend server logic will announce this character set
257 to a client if the negotiationModel bit is set by the client. All server
258 implementors are encouraged to specify this. If a backend server does not
259 specify this a warning is issued using yaz_log(YLOG_WARN,..).
261 Added CCL utility to remove terms (stop words) from resulting RPN
262 tree. This is handled by functions with prefix ccl_stop_words_ .
264 New ZOOM C option, "rpnCharset", which allows client-side conversion of
265 terms in RPN queries.
267 Clean-up the CCL API. Moved some internal structures from ccl.h to
268 private header cclp.h. Changed ccl_parser_create so that a Bibset must
269 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
270 This is replaced by ccl_parser_find_str which takes a string instead.
272 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
273 libyaz.la is the core of YAZ except the generic frontend server and
274 does not depend on POSIX threads anymore. libyaz_server.la is the
275 generic frontend server facilities and uses POSIX thread functionality
276 if available. The libyaz.la no longer depends on POSIX threads because
277 the number of global structures is limited. NMEM no longer re-uses blocks
278 between threads ; it simply free's memory immediately but allocates in
279 "large" chunks as usual. We don't expect any performance penalties
280 because of this. The yaz_log system is still using a global log_level so
281 caution must be taken when modifying it with yaz_log_init_.. +
282 yaz_log_mask_str. This, however, should not cause any trouble because
283 these functions are called during initialization of application code
284 anyway. `yaz-config --libs server` returns libs for server applications;
285 `yaz-config --libs` returns libs for non-server applications.
287 New OID database - with public definitions in oid_db.h. Removed old OID
288 database including the head oid.h and definitions such as enum oid_value
289 and struct oident. The new OID database uses the same string names as
290 before but the 'protocol' is gone. There are now only two representations
291 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
292 converts from string to OID; functions with prefix yaz_oid_to_string
293 converts the other way.
295 Change to emit_term() in CQL-to-PQF query translation: when a term has
296 the /regexp relation modifier, do not process it for leading and
297 trailing "^" and "*", which have quite different meanings in regular
300 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
301 write handlers no longer carries a 'last' parameter. This will make
302 yaz_iconv flush "less" characters. A flush is performed by call to
303 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
305 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
306 removed, because function yaz_query_to_wrbuf does the same.
308 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
309 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
311 Deprecated MARC utility functions removed.
313 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
316 Branch split: YAZ_2_1_55_branch
318 --- 2.1.54 2007/03/16
320 Fix to ZOOM-C so that transparent reconnection is properly handled on
321 connections that are in asynchronous mode.
323 Fixed compilation on OpenBSD 4.0.
325 Large strings in GRS-1 records are now properly displayed in yaz-client.
327 Added character conversion support for "advancegreek"; based on patch from
330 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
331 sequence is met. Before the error was not set so it would be unknown.
333 Adjust yaz-marcdump MARC reader so that it skips until record separator
336 --- 2.1.52 2007/03/07
338 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
339 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
340 fd_set structure used as a bitmask for the FDs to be selected on.
342 Using ACX_PTHREAD macro to check for POSIX threads.
344 Fixed have-vsnprintf check.
346 --- 2.1.50 2007/02/23
348 Fixes for configure on BSD. Bug #900.
350 Added snprintf/vsnprintf wrappers for systems that don't have
351 limits (heavens forbid).
353 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
354 created before all previous tasks were completed and removed from the
355 task queue, the new task could be removed by a mistake.
357 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
359 Implemented pass-through CQL-to-PQF conversions. Bug #861.
361 Fixed bug #832: Problem with MARC/charset in yaz-client.
363 Fixed bug #668: save command line history for yaz-client.
365 Fixed bug #830: pkg-config support.
367 --- 2.1.48 2007/01/23
369 Extended ZOOM result set options with two options that may be read by
370 a client: resultSetStatus and presentStatus with values as specified for
372 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
374 Fixed bug #827: Using SSL fails on Debian etch.
376 Fixed bug #826: Weird looking chars for set of MARC records.
378 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
379 that is treated as an ItemOrder with itemRequest being an XML document
380 external. The value of "doc" is the content.
382 Extended the GFS search facility. New member of bend_search_rr
383 'estimated_hit_count' signals that hits is known to be an estmate
384 (higher or lower than real hit count). New member 'partial_resultset'
385 signals that the search was partial (hit count is lower or equal than
386 real hit count). For Z39.50, the information is stored in resultSetStatus
387 member of SearchResponse APDU. For SRU, the information is signalled
388 via SRU diagnostic 59: "Result set created with valid partial results
391 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
393 --- 2.1.46 2007/01/13
395 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
397 Added ZOOM_connection_peek_event.
399 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
400 the following new functions:
401 ZOOM_event_nonblock, ZOOM_connection_process,
402 ZOOM_connection_get_{socket,mask,timeout},
403 ZOOM_connection_fire_event_{timeout,socket}.
404 The existing blocking event handler, ZOOM_event, is a wrapper for the
405 + blocking ZOOM_event_sys_{poll,select}.
407 Implemented function ccl_xml_config which parses XML version of CCL
408 configuration (bug #798).
410 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
412 Added timings utility (yaz/timing.h)
414 --- 2.1.44 2007/01/03
416 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
419 Fixed bug #779: Rotation of apdu.log fails.
421 Fixed for character set conversions:
422 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
423 Honor G1 set in MARC-8 decoding.
425 --- 2.1.42 2006/12/17
427 Fixed bug #775: char conversion does not handle Alternative UTF-8
430 Implemented function yaz_marc_read_line which parses MARC line format
431 records. There is a wealth of formats out there. So far, this function
432 reads line records produced by yaz_marc_write_line.
434 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
435 more generic and easier to remember(!) options: -i format and -o format
436 which specifies input format and output format respectively - where
437 format is one of "marc", "marcxml", "line", "marcxchange".
439 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
440 does not print anything except warnings for records.
442 For yaz-marcdump, added support for MARC split into files (-s) with a given
445 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
446 spec, at http://www.loc.gov/standards/sru/record-update/
447 This has changed the binary layout of the following structs:
448 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
449 bend_update_rr . Patch by Ko van der Sloot.
451 Added GFS utility function bend_assoc_is_alive which returns 1 if
452 association is still alive (client is connected); 0 otherwise (client
453 closed connection). This allows busy servers to stop working for
456 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
457 been a separate piece of software. This version of ziffy has been modified
458 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
460 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
462 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
463 Client code may now interrogate options such as "init_opt_sort" to
464 find out whether the server claims to support various options.
466 --- 2.1.40 2006/11/27
468 Added utilities yaz_{set,get}_esn to set/get element set name from
471 Removed the build of libyazthread.la. The libyaz.so is the threaded version
472 of YAZ and has been so since YAZ 2.1.10.
474 Implemented ZOOM_record_error which returns error information for
475 record (surrogate diagnostic).
477 --- 2.1.38 2006/10/31
479 Updates for SRU Update by Ko van der Sloot:
480 1. Changed name from "operation" to "action"
481 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
482 versions in the code, marked as 'backward compatible'.
483 3. Added diagnostics for SRU Update.
485 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
487 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
489 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
491 For GFS, fixed problem with SRU diagnostic 'First record position out of
492 range' being issued for 0 hits.
494 zoomtst10 part of Windows Build.
496 --- 2.1.36 2006/10/13
498 Implemented yaz_filepath_comp which splits a path into file path
499 components (required by Zebra 2.0.3+).
501 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
502 BSD inspired license until now so this should not have any real impact on
503 anybody. See http://www.opensource.org/licenses/bsd-license.php
505 Fixed bug #687: Missing log lines.
507 Fixed bug #678: CQL to PQF translation does not preserve double-quote
510 Fixed bug #689: SRU diagnostics to be added.
512 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
513 whether a connection is idle (no more work do do).
515 --- 2.1.34 2006/10/04
517 Change type of optval from long to int for invocation of setsockopt with
518 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
520 Added support for specifying the max log file size for the Generic
521 Frontend Server. The size is given with option -r.
523 --- 2.1.32 2006/09/21
525 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
527 --- 2.1.30 2006/09/17
529 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
532 Fixed bug in Generic Frontend Server that could cause a server to stop
533 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
535 For the generic frontend server, the maximum record size is used as maximum
536 size of incoming packages (SRU + Z39.50). The value until was previously
537 only used in Z39.50 Init negotiation and, later, in a session controlled
538 sizes of records returned. This is controlled using -k option. It can be
539 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
541 --- 2.1.28 2006/09/04
543 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
546 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
548 New option for yaz-marcdump -lpos=value which allows setting a portion
549 of MARC header to a certain value.
551 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
553 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
554 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
556 --- 2.1.26 2006/08/15
558 Fixed problem with SRU mode type (soap, get, post) for yaz-client
561 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
563 --- 2.1.24 2006/08/08
565 Fixed MARC ISO2709 encoding routines to deal with character set
568 Minor changes to GFS logging. Database included in search request log
571 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
572 cached/multiple records.
574 Shared libraries are built by default on Unix+configure.
576 Changed cql2pqf transformation to use a different evaluation order. The
577 new order is: always, relation, structure, position, truncation, index
578 and relationModifier. Old order was: always, relation, relationModifier,
579 structure, index, position, truncation. Note that the the latter ones
580 override former ones for identical attributes.. The new scheme means that
581 it is possible to override any existing attribute with a relationModifier.
582 And also that it is possible to override everything for the index rule
583 (except the ones listed in relationModifier). No order is perfect but this
584 one, we believe, covers more real cases.. The "always" should have been
585 called "default", since the attributes there can be overridden with all
588 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
589 compilation phase, but also for yaz-config --cflags output. This allows
590 us to have public headers with Libxml2 stuff in them . It should also,
591 eventually, make Libxml2 checks redundant in packages using YAZ, such
594 --- 2.1.22 2006/06/15
596 Changed SRU update structure bend_update_rr so that SRU diagnostics are
597 stored in uri, message and details.. Previously diagnostics were stored
598 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
599 compatibility.. but he's probably the only one affected, so.
601 Added support for CCL, compiled on the client side, in ZOOM-C. This
602 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
603 input; the resulting query objects can be used for for searching with
604 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
606 YAZ' configure searches for OpenSSL by default.
608 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
609 SL_CTX_use_certificate_file. See
610 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
611 for more info. Thanks to Ko van der Sloot.
613 --- 2.1.20 2006/06/02
615 Bug #600: SRU GET, POST support for yaz-client. Introduced
616 command 'sru' which selects method SOAP/GET/POST.
618 Allow missingValueAction to be specified for the sortspec string -
619 function yaz_sort_spec. By default, the missing value action is null.
620 Use ! to specify "abort". Use = followed by stringvalue to specify default
623 Ensured that Present-handler (if defined) is called in GFS before any call to
624 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
625 searchRetrieve requests.
627 Documentation for YAZ is now based on the Docbook XML/XSLT using
628 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
629 is no longer depending on jade/openjade or docbook-to-man scripts.
630 PDF is no longer part of the distribution - but can optionally be
631 made using DSSSL/jadetex or FOP.
633 Added retrieval handling support in Generic Frontend Server to support
634 conversion between MARC/XML as well as XSLTtransforms. See
635 etc/yazgfs.xml for an example.
637 Added Authentication support to Generic Frontend Server in SRU
638 mode. Authentication using HTTP Basic is supported, as is the use
639 of 'x-username' and 'x-password' parameters in the request itself.
641 Added support for a new character set MARC8s identical to MARC8 except
642 that it converts combined characters to single Unicode characters in the
643 Latin-1 range (when possible).
645 --- 2.1.18 2006/04/24
647 ASN.1 compiler 0.4: generates brief Doxygen file header for
648 generated .h/.c files.
650 Utility yaz_iconv now supports conversion to MARC-8.
652 New facilities for the MARC module. The reading - and writing of
653 content are separate methods for the yaz_marc_t handle. The following
654 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
655 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
656 format). Write functions have prefix yaz_marc_write_.. The existing
657 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
658 available. Removed support for OAI-MARC and simplexml (not the
659 simplexml from PHP5).
661 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
662 to be returned for this connection.
664 --- 2.1.16 2006/03/31
666 Allow multiple languages and charsets to be specified with
667 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
668 negcharset iso-8859-1,utf-8
670 Translation of proximity nodes from CQL into PQF now works.
672 Moved to automake 1.8, 1.9.
674 Added function yaz_log_set_handler which allows a log handler to be
675 installed. This handler will be called for all log messages. Output
676 to file is also produced; but that can be disabled by passing NULL
677 fname to yaz_log_init_file.
679 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
681 For SRW (including GFS), accept application/soap+xml as content-type
684 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
685 produces NO stylesheet reference even if a default stylesheet is specified
688 --- 2.1.14 2006/03/14
690 Updated Windows package to include yazd.dll + yazd.lib for the
691 Development component.
693 If the environment variable YAZ_LOG is set, then it is used as a
694 string indicating the default level of logging to use if not
695 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
696 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
697 used as before. So, for example, to omit warnings from YAZ logging,
700 cql_transform() now map structure and other attributes before indexes,
701 so that index-specific structures and other attributes can override
702 defaults. So now a combination of mapping specifications such as:
704 index.dc.date = 1=date-modified 4=5
705 does the right thing.
707 cql_transform() now also respects the "always" mapping specification,
708 which establishes an initial set of attributes to be used for all
709 terms except where overridden by more specific attributes associated
710 with the index, relation or modifier.
712 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
713 which mode to use; one of "post", "get" or "soap" (SRW, default).
715 Fixes for yaz_iconv routines: changed trie-based character set conversions
716 to use only non-negative values for bit fields due to Sun's C compiler not
717 supporting negative values.
719 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
720 sequences where not read correctly. Fix by Rustam Usmanov.
722 Updated win/makefile to use options, settings which makes things
723 compile with VS C 2005.
725 --- 2.1.12 2006/02/01
727 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
729 In ZOOM socket code, use select instead of poll on MacOSX.
731 ZOOM-C now support client-side compilation of CQL into RPN that is
732 sent to the server, enabling CQL to be used against all Z39.50
733 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
734 ZOOM_query object, and submit it using ZOOM_connection_search().
735 The CQL-to-RPN translation uses a configuration file, the name of
736 which must be specified in the Connection's "cqlfile" option.
738 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
739 function, which takes as its start-term parameter a ZOOM_query object
740 (which may have had either CQL or RPN set into it).
743 --- 2.1.10 2005/11/29
745 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
746 GFS to support this as well. Backend handler, bend_srw_update, does the
747 update work. Code contributed by Ko van der Sloot.
749 Allow retrieval of Search Result-1 information in ZOOM by the use of
750 options that are attached to a result set. ZOOM documentation updated
753 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
754 UTF-8 conversion. Patch by Raj Patel.
756 Added option -m to GFS to control formatting of timestamps in log file.
758 Added 'exit' as synonym for 'quit' in yaz-client
760 Added support for specifying SRW resultSetId + resultSetIdleTime in a
761 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
762 for the new members. Patch by Ko van der Sloot.
764 Added support for SRU POST. It is supported for content-type
765 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
767 Do not build the separate Multi-threaded (MT) library libyazthread.la.
768 Instead make the library libyaz.la multi-threaded. Threading as a whole
769 can still be disabled by configure option --disable-threads. Previosly,
770 with older GLIBCs there were problems with MT libs under Apache. This
771 has now been fixed a long time ago.
773 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
776 CQL module modified to be case insensitive for relations/indexes/operations.
778 Fixed bug in CQL transform code: incorrect value relationModifieder
781 Added 'show all' command for yaz-client which retrieves all results
784 Added new yaz-client, xmles, which takes a (private) OID and
785 a document to be sent as an extended service request.
787 Describe new yaz-client commands wait_response and set_auto_wait.
789 Increase TCP/IP listener backlog from 3 (which I am guessing was
790 copied from the SunOS manual entry way back when) so SOMAXCONN, so
791 that the socket will queue as many incoming connections as it's able
792 to handle ongoing connections. In other words, it will never now
793 refuse a connection that it would be able to handle merely because
794 it's not got around to accepting() enough of the pending connections
795 yet. This is the behaviour anyway under Linux, where the listen()
796 argument is ignored; but not under BSD and on systems such as
797 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
798 YAZ-based servers should now be uniform across operating systems in
801 yaz-marcdump uses 64-bit file access on some systems. This is enabled
802 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
803 This allows yaz-marcdump to read large MARC batches (>2 GB).
805 Modified all YAZ source files - except the source which is auto-generated
806 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
809 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
810 corresponding to the existing *_setl() function. These allow option
811 values containing arbitrary valuues.
813 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
814 ZOOM_resultset_sort() in new applications. Its behaviour is identical
815 except that it returns an indicator of whether or not the sort
816 criterion was accepted (0 for OK, -1 for invalid).
820 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
821 MARC output rather than returning "new" buffer.
823 yaz-client warns about unknown init options.
825 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
829 Added support for SRW sort in Generic Frontend Server. Patch
830 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
831 sortKeys - or NULL if none is provided.
833 Fixed bug #307: It was impossible to specify indefinite/no timeout
834 for ZOOM_event. Special timeout value -1 now means indefinite timeout
837 Added support for multiple languages and charsets to be specified in
838 ZOOM. Each charset/language is separated by a blank. If negotiation is
839 in effect in init-response, Option
840 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
841 Code based on patch by Vasiliy Osadchuk.
843 Fixed bug #306: infinite recursion that occurred when calling
844 yaz_log_level_init as the first call (before other log level or
847 Fixed bug in scan handling in front end server: if preferred-Position-In-
848 Response was non-present, a NULL pointer referece was performed.
852 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
853 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
854 now defined for all those error codes. So instead of putting 109 in
855 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
856 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
858 Modified the yaz-marcdump utility to skip garbage bytes between MARC
861 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
863 Program yaz-client now exits and produces an error message if multiple
864 Z39.50 servers are specified on the command line (none or one allowed
867 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
872 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
874 Fixed bug #272: Preserve spacing for CCL terms.
878 Added support for virtual hosts and multiple backend servers for
879 the YAZ frontend server. The configution is XML based and
880 support specificition of CQL to RPN mappings and explain information.
881 See section "Virtual Hosts" in the YAZ manual.
883 Extended OPAC display utility. OPAC display utility renders
884 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
885 to supplement yaz_marc_decode_wrbuf.
887 Fixed a bug in MARC decoder that could caused it to crash for some
888 invalid MARC records. More diagnostics and warnings where added in
889 XML output (warnings, etc are stored in comments).
891 --- 2.0.34 2005/02/08
893 Fixes for UNIX domain sockets. Bug #261.
895 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
897 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
898 Added yaz_marc_subfield_str which defines subfield lead string which is
899 used in YAZ_MARC_LINE format. Default string is blank+$. Added
900 yaz_marc_endline_str which defines end of fields string used in
901 YAZ_MARC_LINE format. Default string is newline.
903 Experimental support for MarcXChange. This format can be produced
904 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
905 http://www.bs.dk/standards/MarcXchange.xsd
907 Added yaz-client commands scansize that sets maximum number of
908 entries to be returned by scan.
910 --- 2.0.32 2005/01/11
912 Added support for SRW scan in yaz-client and Generic Frontend Server.
914 * Added whereInList member to SRW Scan Term.
916 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
918 Fixed NMEM system to return aligned blocks on the smallest boundaries
919 that are suitably aligned for all possible types on the particular
920 architecture YAZ is being built for.
922 --- 2.0.30 2005/01/04
924 Fixed numerious warnings that was issued with newer versions of GCC.
926 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
927 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
930 Make YAZ Generic Frontend Server slightly faster.
932 Enhance (and reduce) logging for Generic Frontend Server.
934 Revert YAZ log system so that it flushes every write operation
935 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
937 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
938 instead of LOG_, due to name clash with syslog(3). LOG_ are still
939 present. New applications should define YAZ_USE_NEW_LOG=1 - this
940 will effectively disable old definitions.
942 --- 2.0.28 2004/11/09
944 Added yaz_log_time_format which specifies log format using
947 Added yaz_log_module_level which returns mask for a module. Value
948 is non-zero mask a if module is enabled; zero if disabled.
950 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
951 in include/yaz/cql.h.
953 Fixed bug #176: Dont throw diagnostics on empty SRU args.
955 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
957 Fixed bug #172: RPM builds does not enable SSL.
959 Doxyfile.in part of dist. Doxyfile generated by configure.
961 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
962 are given and the corresponding component does not exist.
964 Extend CCL documentation in YAZ reference. Describe r=r.
966 --- 2.0.26 2004/10/01
968 Fixed MARC->MARCXML conversion to properly deal with
969 fields, subfields, indicators having non-ASCII characters.
971 Fixed MARC->MARCXML conversion so that ASCII control characters
972 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
975 Added YAZ GFS support for conversion from Z39.50 surrogate
976 diagnostics to SRW surrogate diagnostics.
978 Bug fix: YAZ GFS did not return schema in explainResponse.
980 --- 2.0.25 2004/09/30
982 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
983 now converts recordSchema to elementSetName as well as schema URI.
985 Fixed bug in COMSTACK that prevented HTTP request packages from being
988 --- 2.0.24 2004/09/29
990 Added CCL facility r=r "range" which is similar to r=o "ordered" but
991 does not require white-space before and after the dash in a range, e.g.
992 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
995 Fixed a few AC_TRY_LINK configure tests that did not operate properly
996 due to new GCC removing "redundant" code.
998 Added yaz-client commands scanpos and scanstep that sets preferred
999 position and step-size for scan.
1001 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1003 Added CCL utility ccl_qual_buf which parses one or more CCL
1004 spec lines in a buffer.
1006 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1007 of name and value - ignoring empty lines and comments.
1009 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1011 Added odr_get_element_path which returns current element path for an
1012 ODR handle. This utility is useful in error handling or user-defined
1015 Added ODR_PRINT utility odr_set_stream which is is a more generic
1016 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1017 to a write function and pointer to close function. The close function - if
1018 non-NULL - will be called during odr_destroy.
1020 Fixed bug in CCL parser where truncation char was not removed from
1021 right side when truncation=both was in effect.
1023 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1026 --- 2.0.23 2004/08/11
1028 Fix buffer overrun in CQL parser when dealing with proximity (%).
1030 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1031 to UTF-8/UCS conversion is now only based on codetables.xml.
1033 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1035 --- 2.0.22 2004/08/06
1037 Add support for more "commit changes" in ZOOM (uses Extended Services).
1039 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1042 Yet another small fix for configure of SSL.
1044 --- 2.0.21 2004/05/14
1046 Fix SSL libs for configure when --with-openssl=DIR is given.
1048 --- 2.0.20 2004/05/10
1050 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1052 SSL comstack now uses yaz.pem certificate file on server side
1053 by default. Certificate filename can be configured by calling
1054 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1056 Fix bug regarding multiple calls to ZOOM_connection_connect.
1058 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1060 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1061 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1063 ZOOM now allows inspection of X509 peer certificate for verification.
1064 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1066 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1067 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1068 as "modular" but it simplifies things.
1070 Added cs_get_peer_certificate to that returns peer X509 PEM.
1072 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1073 NULL if SSL is unavailable.
1075 Documentation about MARC decoding tools.
1077 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1079 --- 2.0.19 2004/03/30
1081 Rename CHANGELOG to NEWS to follow GNU style packing.
1083 Fix bug with missing initialization of member in init_diagnostics.
1084 This bug affects threaded version of GFS server.
1086 --- 2.0.18 2004/03/20
1088 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1091 Ensure zlib.dll is packed with Windows install.
1093 --- 2.0.17 2004/03/17
1095 Fix encoding of xsd:string to use text instead of CDATA.
1097 Fix endless loop in CQL parser with unbalanced ".
1099 Use a more compact way to store MARC-8 conversion tables.
1101 --- 2.0.16 2004/03/16 Debian only
1103 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1106 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1111 --- 2.0.15 2004/03/01
1113 Another fix for decoding of XML packed records.
1115 --- 2.0.14 2004/02/25
1117 Fixes for Chunked encoding. White space not ignored after length spec.
1119 Update NS and use default NS for SRW diagnostic elements.
1121 --- 2.0.13 2004/02/23
1123 Implement ZOOM_resultset_cache_reset which resets record cache.
1125 Implement ZOOM_resultset_sort which sorts a result set.
1127 Implement chunked HTTP transfer.
1129 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1131 --- 2.0.12 2004/02/16
1133 Added member 'schema' to bend_explain_rr structure so that backend
1134 can specify explain record identifier. Defaults to Zeerex 2.0.
1136 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1138 --- 2.0.11 2004/02/16
1140 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1143 Added init command for yaz-client which sends "extra" init request.
1145 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1146 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1148 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1150 Make ZOOM error code for "invalid query".
1152 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1154 --- 2.0.10 2004/02/05
1156 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1159 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1161 Added option -p <file> to make Generic Frontend Server to write PID file.
1163 Added option -D to put Generic Frontend Server in background on its own.
1165 Make ZOOM C recognize option "password". If unset, "pass" is used
1166 (for backwards compatibility).
1168 Fixed a bug in Generic Frontend Server that could make it crash if a
1169 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1172 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1173 Must be issued before open, in order to be in effect.
1175 --- 2.0.9-6 2004/01/12 Debian/Windows
1177 Make the SRU server more picky WRT unknown params, etc.
1179 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1181 New YAZ client command, options, that sets Z39.50 options.
1183 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1184 options from a string of tokens (one token for each option bit).
1186 Update SRW diagnostic code messages.
1188 --- 2.0.9-5 2004/01/07 Debian/Windows
1190 Handle user defined stylesheet for SRW/SRU.
1192 --- 2.0.9-4 2004/01/06 Debian/Windows
1194 Fix bug in decoding of Content-Length.
1196 --- 2.0.9-3 2004/01/06 Debian/Windows
1198 Fix a bug with decoding of XML packed records.
1200 --- 2.0.9-2 2004/01/05 Debian only
1202 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1204 Fix bug in SRW/SRU diagnostics decoding.
1206 --- 2.0.9 2004/01/05
1208 Fixed bug in Generic Frontend Server which could drop records exceeding
1209 preferred message size. Reported and fixed by Irina Dijour.
1211 Fixed calculation of package size for structured records in Generic
1212 Frontend Server. Reported and fixed by Irina Dijour.
1214 Fixed namespace for SRW/SRU diagnostics.
1216 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1218 --- 2.0.8 2003/12/22
1220 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1221 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1224 CQL changes to reflect recent changes to the specification:
1225 * Documentation talks about context sets instead of index sets.
1226 * Documentation talks about indexes instead of qualifiers.
1227 * The CQL-to-PQF transformer's configuration file now uses
1228 "index.set.name = <attributes>" instead of the old form
1229 "qualifier.set.name = <attributes>". (Both forms are still
1230 understood but the latter is deprecated.)
1231 * CQL terms with no explicit index specified are now interpreted as
1232 cql.serverChoice instead of srw.serverChoice (which of course
1233 behaves exactly the same.)
1235 --- 2.0.7 2003/12/16
1237 MARC conversion can now generate ISO2709 output in another
1238 character set. yaz-marcdump uses this facility if you invoke it
1241 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1242 functions from there can be used from C++.
1244 --- 2.0.6 2003/12/04
1246 Frontend server now transfers memory from decoded packages to stream
1249 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1250 references to show up.
1252 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1253 the ZOOM Abstract API. The older names for the same options are still
1254 also supported for the benefit of old applications.
1256 ZOOM-C supports "implementationId" and "implementationVersion" options
1257 to go along with "implementationName". These allow the user code to
1258 specify identification strings to be sent to servers.
1259 Add OID for the new ExtLite attribute set.
1261 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1262 as requested/supplid by Ere Maijala <ere@atp.fi>
1264 For generic frontend server, reverse the order of
1265 "toolkit-supplied / application-supplied" strings sent as implementationId,
1266 Name and Version. Also, remove the spaces around the slash. This brings
1267 the GFS in line with the behaviour of ZOOM-C on the client side.
1269 Add function ZOOM_scanset_display_term.
1271 yaz-client shows scan displayTerm if present.
1273 Utility yaz-iconv is now installed by default along with the man page
1276 Extend configure check for OpenSSL to use pkg-config where available (such
1279 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1280 server to specify uid/gid/mask for socket using the format
1281 unix:[user=uid,][group=gid,][umask=mask,]file=path
1282 If file= is omitted the existing format is assumed, e.g.
1284 in which case the mask is 0666 (rw for everybody).
1286 Major restructure of YAZ source. All source in libyaz is in src directory.
1287 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1288 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1290 Added man page for utility yaz-marcdump (used to be called marcdump).
1291 yaz-marcdump is installed by 'make install'.
1293 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1294 of incoming package failed.
1296 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1298 Change prototype of odr_perror: add const to message string.
1300 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1302 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1303 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1304 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1305 DNS lookup. There should not be any compatibility problems with this
1306 assuming that blocking=1 or 0 is used.
1308 Fix bad reference in UNIX comstack in function cs_addrstr.
1310 Fix for compilation on AIX.
1312 The generic front-end server (server/seshigh.c) now supports returning
1313 Init diagnostics to the client in User-information-field, in
1314 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1317 --- 2.0.4 2003/09/04
1319 Allow any CQL relation (not just all,any,exact,scr).
1321 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1322 that features the same UI.
1324 Implemented command update0 in YAZ client which is equivalent to
1325 update but uses old of Ext Update ASN.1.
1327 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1328 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1329 Previously no OID was used for this info.
1331 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1332 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1333 returns 'malformed search term' otherwise.
1335 SortResponse member resultCount now set to NULL in sort handler of
1338 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1341 Add three new utility functions for translating OIDs between various
1342 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1343 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1344 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1345 char *oid_to_dotstring(const int *oid, char *oidbuf);
1346 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1348 Reverted modifications for ES Update definition for z_IU0Update
1349 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1350 is back to YAZ 2.0.2.
1352 String value attributes for CCL parser.
1354 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1355 which their FirstSearch server returns in Init responses, sometimes
1356 carrying useful diagnostic information when Init fails. This has the
1357 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1358 "z39.50/oclcui.asn", where its definition is somewhat different from
1359 what OCLC document on their web-site, as required to interoperate with
1362 Support for anonymous authentication in yaz-client. Use the command
1365 * Fix the OID of the Index Data-local "admin" Extended Service from
1366 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1367 the 1000, which indicates a locally-defined OID, was a mistake.
1369 --- 2.0.3 2003/06/20
1371 Fix CCL directive @case handling so that it affects string match for
1372 both CCL keywords and qualifiers.
1374 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1375 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1376 Decoder has been updated with ASN.1 changes as listed in
1377 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1378 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1379 z_IUUpdate, remains unchanged.
1381 ZOOM_record_get may now return a record in a specific character set.
1382 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1383 "from" is the character set of record as returned by target. "to" is
1384 the character set to be returned. If omitted, "to" is UTF-8.
1386 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1388 New ODR utility, odr_getelement, which returns name of element for
1389 which encoding/decoding failed.
1391 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1392 in cases where a required element was omitted.
1394 Bug fix: some MARC8 sequences were not converted.
1396 New ZOOM option "step" which specifies number of records to be
1397 retrieved in one chunk. Used in conjunction with "start" and "count".
1399 SRW support for yaz-client. Use scheme http: to use it, e.g.
1402 yaz-client no longer does (un)intelligent character set conversions
1403 by default. Can be enabled with charset and marc_charset commands.
1405 xmalloc trace fix for 64-bit systems such as DEC alpha.
1407 Solaris 2.6 compile fix.
1409 New function, cql_strerror() translates SRW error codes, as returned
1410 by cql_transform_error(), into human-readable English strings. Used
1411 in yaz-client diagnostics when appropriate.
1413 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1414 converts it into a type-1 query which is sent to the server. This
1415 makes CQL available for use with all Z-servers, as opposed to the tiny
1416 minority that can handle CQL queries themselves.
1418 --- 2.0.2 2003/04/28
1420 New Debian package layout similar to the Redhat Package layout.
1422 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1423 and search result respectively.
1425 --- 2.0.1 2003/04/25
1427 Redhat package is now several packages: libyaz (runtime libraries),
1428 libyaz-devel (development and documentation, and yaz (utility programs).
1429 Package spec file by Morten Bogeskov.
1431 New member 'schema' in struct bend_fetch_rr which the name of requested
1432 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1433 handler MAY set this to reflect the schema of the returned record.
1435 New member 'display_term' in struct scan_entry. GFS now sets member entries
1436 and allocates scan entries to be filled by user scan handler. In previous
1437 version, entries member was allocated by the scan handler. That still works,
1438 but the GFS will ignore member display_term - assuming it was NOT set by
1439 the handler. The fact that the GFS now allocates the entries both allows
1440 for new members and makes a scan handler easier to write.
1442 Fix CQL lex buffer overflow.
1444 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1445 SRU default recordPacking is string.
1447 SRU protocol support for frontend server.
1449 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1451 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1453 Added scan for the ZOOM shell (zoomsh).
1457 * String Identifers for Schemas (Amendment 5).
1458 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1459 Old definition for schema
1460 Odr_oid *schema; /* OPT */
1465 Z_InternationalString *uri;
1466 #define Z_Schema_oid 1
1467 #define Z_Schema_uri 2
1470 * resultCount parameter to Sort Response (Amendment 1).
1471 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1473 Support for SRW 1.0 over HTTP. This is an optional feature and
1474 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1477 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1478 on the same port. SRW SearchRetrieveRequests are mapped
1479 to bend_init,bend_search,bend_fetch,bend_close.
1481 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1483 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1484 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1486 ZOOM connections are SRW based if schem http is used for hostname
1487 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1488 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1490 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1491 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1492 distance=n, order=true/false, relation=le, prox unit=word. If
1493 n is omitted, distance 1 is used.
1495 Fixed problem with C compiler include path in wrong order.
1497 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1498 on Solaris. Patch from Ko van der Sloot.
1500 New MARC decode API. All new functions operate on a yaz_marc_t
1501 handle. The most important new functions are: yaz_marc_create,
1502 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1503 decode and destroy respectively. Decoder can produce formats
1504 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1505 include/yaz/marcdisp.h.
1507 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1508 to UTF-8, UCS-32, wchar_t or Latin-1.
1510 * Prototypes for yaz_iconv_-functions moved to separate header
1511 include/yaz/yaz-iconv.h.
1513 Make a few private functions 'static' in unix.c. This prevents
1514 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1516 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1517 are set when Init Response is received.
1519 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1520 but returns diagnostic set as well.
1522 New function yaz_strerror which is a portable wrapper for
1523 strerror/strerror_r/GetLastMessage.
1525 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1526 is returned for MARC. If type is "oai", then OAI MARC is returned.
1528 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1531 --- 1.9.2 2002/11/26
1533 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1535 Fix bad race conditions on SIGTERM and terminate gracefully in
1538 Move retrieval (data1) module to Zebra since nobody seems to be
1541 Add GRS-1 render for ZOOM using same format as yaz-client.
1543 --- 1.9.1 2002/10/05
1545 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1547 Fix broken ESpec handling in data1 module.
1549 SGML reader parses comments and makes them part of the data1 tree.
1551 Added several type casts so that YAZ compiles as C++ code.
1553 ZOOM didn't handle PDU encoding failures properly.
1555 Added more Bib-1 diagnostics (approved extensions).
1557 GNU configure: better check for iconv.
1559 More portable use of accept, getpeername. Check for socklen_t. Use
1560 int/size_t if socklen_t is not defined.
1564 PQF parser rejects bad queries - including those with extra
1565 characters in them. PQF parser used to silently ignore that.
1566 Cleaner API for PQF added, which allows you to get detailed
1567 error information for bad queries (see yaz/pquery.h).
1569 Fixed bug in ZOOM_record_get for type "database".
1571 Implemented mini iconv library supporting conversions between
1572 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1574 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1576 --- 1.8.9 2002/08/20
1578 Fixed ZOOM C record cache so that preferredRecordSyntax and
1579 elementSetName is used to check for already fetched records.
1581 --- 1.8.8 2002/08/02
1583 Added three members in bend_initrequest structure to facilitate
1584 character set negotiation.
1586 Fixed a bug in frontend server that could cause indefinite
1587 loops under rare conditions.
1589 Revised character set utilities (charneg.h) so that encoding
1590 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1592 For PQF, directive @term <type> sets term type for Scan/Search.
1593 Here <type> is general, string, numeric, null. The term type
1594 is inherited - just like @attr.
1596 New call odr_set_charset that sets character set conversion for
1597 international-strings on a ODR stream. Prototype is:
1598 int odr_set_charset(ODR o, const char *to, const char *from);
1599 The InternationalString is still represented as C string in YAZ
1600 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1601 won't). On the protocol level, you can use any encoding.
1603 Support for UNIX sockets in ZOOM.
1605 Solaris recv sometimes returns errno == ENOENT. It is treated as
1606 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1608 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1609 both client and server. Code by Morten Bogeskov.
1611 --- 1.8.7 2002/05/22
1613 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1614 that they can be used directly from Visual Basic. You must recompile
1615 your windows APP if you're using ZOOM.
1617 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1618 Commands "lang" and "charset" sets language and character set respectively.
1619 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1620 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1622 Attributes from multiple CCL fields may be OR'ed rather than merged
1623 using directive "@field or". Fields are still merged by default -
1624 equivalent to "@field merge".
1626 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1629 Fixed bug in zget for parameter ExtendedServicesResponse.
1633 --- 1.8.6 2002/03/25
1635 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1637 Client displays USR.1:SearchResult-1 (hits per term).
1639 Additional Search Info for search in Generic Frontend Server.
1641 Fixed CCL parsing of "field=s".
1643 WIN32 installer - using the excellent NSIS software from nullsoft.
1645 Fixed CCL parsing of "field = - <number>".
1647 Added function yaz_marc_decode that decodes MARC for line mode
1648 display or XML (similar to that used by JZKit).
1650 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1651 Z39.50. But ISO/ILL was, however.
1653 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1654 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1656 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1657 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1659 --- 1.8.5 2002/02/03
1661 New YAZ client features: Command completion and new commands:
1662 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1663 Code provided by Jacob Poulsen.
1665 New call oid_trav, that visits all registered OIDs via callback.
1667 Function ZOOM_record_get now returns const char pointer rather than
1668 void pointer. It saves a lot of type casts.
1670 For YAZ client, command "auth" now allows you to set authentication
1671 in IdPass style. It is enabled when three tokens are given - order
1672 is user, group and password.
1674 Fix memory leaks in MARC record handling for ZOOM.
1676 New option for YAZ client, -k <kilobytes> that sets
1677 maximum record size. Similar to -k option for generic frontend
1678 server and yaz-ztest.
1680 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1682 Prefix query parser reports "fail" when bad attribute set is given.
1684 Fix in MARC decoder. Proximity logging. Fix for attribute set
1685 in scan handler for server. Patches by Shigeru Ishida.
1687 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1690 Configure option --with-openssl=<dir> now works when a directory is
1691 specified. Patch provided by Morten Bogeskov.
1693 New option for YAZ client, -u <auth>, that sets authentication.
1695 ZOOM fix: error information was sometimes "missing", since error
1696 was cleared/reset too when it shouldn't.
1698 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1700 --- 1.8.4 2002/01/04
1702 Scan for ZOOM API. New object ZOOM_scanset. New functions
1703 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1704 ZOOM_scanset_destroy.
1706 New ZOOM function, ZOOM_connection_last_event, that returns type
1707 of last event (such as "receive data", "send data", "apdu received",
1710 New ZOOM option, schema, that specifies schema for retrieval.
1712 New CCL feature. Qualifiers can be aliases for one or more
1713 other qualifiers (if more than one is given, OR is used).
1715 ZOOM uses named result sets if target supports it.
1717 Two new YAZ client commands: . (dot, which sources a script of YAZ
1718 client commands), and ! (to execute shell command.). Implemented
1721 Working on Debian packages.
1723 --- 1.8.3 2001/11/19
1725 YAZ client enables named result sets only if target supports it.
1727 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1729 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1730 with key="host" to get same result.
1732 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1733 Function Z3950_resultset_record(s) returns references to records
1734 "owned" by resultset. To become owner use Z3950_record_clone.
1736 Function z_ext_record handles Extended Services. Thanks to
1739 --- 1.8.2 2001/11/12
1741 CCL Parser fix: ignore token comma when dealing with and-lists.
1743 Documentation updates for COMSTACK.
1745 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1746 Changed prototype Z3950_records. For some functions, int parameters
1747 were changed to size_t.
1749 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1752 New MARC decode/display function, marc_display_exl, which properly rejects
1753 non-ISO2709 records. YAZ client uses it.
1755 --- 1.8.1 2001/10/29
1757 Fix bug: local attribute set wasn't set correctly in PQF strings.
1761 * Old Z39.50 codecs no longer supported.
1763 Added ZOOM C binding. See http://zoom.z3950.org/
1765 Renamed states for COMSTACKs to avoid confusion with events.
1767 Implemented cs_look and proper cs_rcvconnect.
1769 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1771 Configure detects POSIX threads on OpenBSD.
1773 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1774 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1776 When error is returned from present handler, non-surrogate diagnostic
1777 is returned in present response (and fetch handler is no longer called).
1779 * Minor adjustments to pquery parser (PQF). Token characters may be
1780 escaped by using backslash (C-style).
1782 PQF parser allows string attribute values to be specified. For @attr,
1783 non-numeric characters after the equal-sign are treated as strings
1784 (e.g. @attr 9=title).
1786 CCL trunction character may be defined (@truncation in file)
1788 * function zget_ExtendedServicesRequest sets waitAction to
1789 waitIfPossible (was wait).
1791 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1794 CCL operator names may be set in field definition files (CCL_bibset).
1795 See ccl/bib1 for an example.
1797 Fixes in ASN.1 compiler for C++ compatibility.
1799 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1800 and "op_or" to avoid conflict with C++.
1802 Fixed problem with GNU readline detection on Redhat 7.0.
1804 Added step-size for Scan backend handler.
1806 Fixed bug that made the frontend server crash when no attribute
1807 set was specified for scan.
1809 Front-end server automatically switches to original working directory
1810 when installed as an NT service. Previously -w had to be specified to
1813 Added extended attributes for retrieval module (data1), so that data1
1814 records carry d1_readXML/SGML attributes. d1_read also supports
1815 null-data rules ( <tag/>)
1817 On UNIX when POSIX threads are available, a separate library libyazthread
1818 is created. Programmers should link with that library and the yaz library
1819 when using threads. The reason for the split was that some applications
1820 on Linux, such as Apache, doesn't work well when using shared objects that
1823 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1824 (or any frontend server) in SSL mode by specifying ssl: followed by
1825 address. Only tested on UNIX.
1827 Added feature for CCL module. Virtual structure s=al or s=ol generates
1828 and-list and or-list respectively instead of phrase search.
1832 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1833 log_mask_str. This was done to avoid name conflicts with other libraries
1834 (such as other PHP extensions).
1836 Added raw OID member for preferred record syntax (request_format_raw)
1837 and returned record syntax (output_format_raw) for backend fetch method.
1839 Config file yaz-config now accepts options so that it returns specific
1840 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1842 Shared library support for UNIX using GNU libtool.
1844 * Modified backend interface. Request/Response struct's replaced by
1845 one read/write C struct. For example bend_fetchrequest and
1846 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1847 Every handler - even search has to be registered in bend_init
1848 handler. This means that the YAZ library no longer refers to
1849 external functions and it makes it possible to make the whole
1850 thing a single DLL/SO.
1852 Added Segment handler for backend server.
1854 Added Zmbol/Zebra administrative functions to YAZ client.
1856 Threaded frontend server on UNIX (when POSIX Threads are available).
1857 Starting the server with option -T enables multi-threading.
1861 Added configure option --enable-comp/disable-comp to control use
1862 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1863 located in sub directory asn.
1865 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1866 in ${exec_prefix}/bin along with the other programs yaz-client and
1869 GNU automake used to maintain makefiles.
1871 Added several OID's.
1873 Changed retrieval module so that we can load records with no abstract
1874 syntax defined. Tagpaths in these records are fully composed of string
1877 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1881 On UNIX, the generated makefile now supports a proper 'make install'.
1882 The prefix can be set via GNU configure to set the install location
1883 (default is /usr/local).
1885 * YAZ programs client and ztest were renamed to yaz-client and
1886 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1887 locations, such as /usr/bin,/usr/local/bin,etc.
1889 * YAZ Header files were moved from include to include/yaz. YAZ Header
1890 files are referred to as include <yaz/log.h> rather than <log.h>.
1891 The YAZ include path (-I ..) is therefore the same as before. Programmers
1892 should update their #include statements or use -Ipath/include/yaz
1893 instead. The main motivation for doing this change is that YAZ header files
1894 can be installed in "standard" locations /usr/include,/usr/local/include
1895 without introducing conflicts, since ALL YAZ header files are stored
1896 in subdirectory yaz (under /usr/include for example).
1898 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1899 rather than project/workspace files. We switched because project files
1900 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1903 Changed name of logging function, logf, to yaz_log, to prevent name
1904 clash with some math-log functions. The YAZ header log.h defines logf
1905 to yaz_log (#define) so there should be no incompatibilities by this
1908 Added bend_start/bend_stop handlers for server. These handler are
1909 called on start/stop of server. For windows they are called whenever
1910 a service is started/stopped.
1912 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1913 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1914 in util/yc.tcl. The auto-generated C code structures are, in a few
1915 cases, incompatible with the old decoders. There are differences in the
1916 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1917 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1918 The preprocessor variable ASN_COMPILED is defined when the compiled
1919 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1920 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1921 wish to use the old encoders/decoders you can specify --disable-yc
1924 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1925 version so that it supports both new - and old version of DB Update
1927 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1928 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1929 change. The name parameter can be set to 0 in which no name is specified
1930 for the construction. The macros odr_implicit and odr_explicit sets name
1931 parameter to zero for the construction involved. New macros
1932 odr_implicit_tag and odr_explicit_tag are similar to the others,
1933 except that a name parameter is added. For programmers' that don't use
1934 ODR they probably only need to change the call to z_APDU and z_External.
1936 Added access control facility by interfacing the TCP wrapper library.
1937 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1938 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1939 name of the daemon and enables the access control as specified in
1940 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1942 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1943 den Dool <H.M.vdnDool@kub.nl>.
1945 Added reference ID parameter to most functions in server API - refer
1946 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1948 Changed name of ccl library to libccl.a (was ccl.a).
1950 Fixed bug in decoder for Explain (Category TargetInfo).
1952 Added support for GNU readline in client. Thanks to Jacob Poulsen
1953 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1955 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1956 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1957 IMPLEMENTATION! This change was made to the development version before
1958 the ZIG decided to retract the amendment. If any users MUST be
1959 compatible with the original Update definition, PLEASE CONTACT US, and
1960 we will include a separate definition corresponding to the old Update
1961 ES. Note that because of the change to the ASN.1 of the
1962 TaskPackageRecordStructure we cannot define a single structure that
1963 will support both versions.
1965 * Added const modifier to buffer parameter for some ODR/BER encoding
1966 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1967 completeWAIS, odr_dumpBER.
1969 Fixed bug in client.c which caused a crash when a scanResponse didn't
1970 contain positionOfTerm.
1972 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1973 * will cause an error in a client if a non-YAZ target sends both a
1974 * list of Scan entries and non-surrogate diagnostics.
1976 Retrieval module enhancements. Tag sets may be typed in the reference
1977 to it. From the .abs-file the "tagset" directive takes a third optional
1978 integer type for the tag set referenced. From a .tag-file the "include"
1979 directive takes a third optional type as well. The old "type" directive
1980 in the tag set itself is still recognized but acts as the default type
1983 Backend interface change. Individual Scan terms returned from bend_scan
1984 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1985 in include/backend.h.
1987 Retrieval module enhancements. Multiple tag sets and attribute sets may
1988 be specified in abstract syntax specs. Revised the error/warning for
1989 logging messages reported by the retrieval module when reading the
1992 Object Identifier system (oid_..) changed. The API is backwards
1993 compatible but the oid-routines now allocates new OID's when needed.
1994 Raw OID's may be specified in oid_getvalbyname.
1996 YAZ now uses GNU configure to generate Makefile(s).
1998 * Minor changes in some of the member names of DeleteResultSetRequest and
1999 DeleteResultSetResponse. See include/proto.h.
2001 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2002 and added member 'languages' in TargetInfo (which was missing).
2004 Changed the way attribute sets are handled in the retrieval
2005 module. These are now cached, just like the abstract syntaxes
2008 Changed YAZ so that it links with compiled ASN.1.
2010 Added Explain-schema definitions and mapping routines. The following
2011 Explain categories have been implemented: AttributeDetails,
2012 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2014 Fixed minor bug in Windows version of Server Library.
2016 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2018 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2020 Added EXTERNAL: UNIverse Resource Report (non-standard).
2022 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2023 ENUMERATED and SET OF.
2025 * Added 'const' to some of the char pointer arguments for the
2026 functions, data1_read_node, data1_getelementbytagname,
2027 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2030 Fixed bug in data1_insert_taggeddata - the last_child member of
2031 parent wasn't initialised.
2033 * Changed data1_read_record and data1_read_node so that the supplied
2034 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2035 doesn't refer to any parts of the "SGML"-buffer.
2037 Fixed bug in server library (Windows version of statserv_remove).
2039 * Changed code so that it compiles as C++. The type definition
2040 of Odr_fun which is a member of Odr_arm was changed. The result is,
2041 that an explicit typecast is needed for the fun pointer when
2042 using Odr_arm - as in:
2043 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2045 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2047 Implemented the new structured date and time definition as approved
2048 by the ZIG. Added schemaId element to the specificTag in Espec-1
2049 (also approved at the last ZIG). Thanks to RVDM.
2051 Added some Object identifiers (RVDM).
2053 Changed the Update Extended Service (RVDM).
2055 Added command "refid" to client which specifies referenceId for
2056 the following requests.
2058 Implemented extended service handling for server. See ztest.c
2059 for an example as well as backend.h. New handlers are registerd
2060 in the Init handler.
2062 * Changed interface for sort in server.
2064 Added new members to statserv_options_block. It allows a server
2065 to read options from another source than just the command line. Thanks
2066 to Charles Woodfield.
2068 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2069 renamed to zboolean. Some C++ compilers complained about the name.
2071 Minor changes to gils.abs. Added index 's' (sort) on title
2072 and date/time-last-modified.
2074 --- 1.4pl2 1998/1/30
2076 Fixed bug in server library regarding inetd mode (-i). This bug
2077 was introduced by release 1.4.
2079 --- 1.4pl1 1998/1/29
2081 Added sort facility in client and backend server interface.
2083 Fixed problem with dependencies in Makefile(s).
2085 Fixed bugs for encoders/decoders of extended services and
2088 Implemented sub-tree feature for schemas. Sub-trees are
2089 referenced in *.abs-files. See explain.abs for an example
2090 of the use of this feature.
2092 Modified bib1.att; local attributes for ANY didn't include
2093 ANY itself (only affects use of the retrieval module).
2095 Fixed bug in plain SGML reader in function data1_read_node:
2096 tags with prefix "var" was incorrectly interpreted as variants.
2098 Added feature "sub-schemas" to enable references to - and definitions
2099 of - group of elements.
2101 * Removed member parent from type data1_element (in data1.h).
2103 Implemented function odr_nullval() that returns the value of
2106 * Removed member num_children from data1_node (in data1.h).
2108 Made NT service interface part of the server library. The
2109 function statserv_main uses the NT service when required and
2110 calls the statserv_start / statserv_close routines.
2112 Routine zget_SearchRequest and zget_PresentRequest fills
2113 resultSetName/Id member with "default" instead of "Default".
2115 Fixed memory leak in server. Request queue member wasn't freed.
2117 Fixed nmem_exit so that memory is freed.
2121 Revised the CCL parser utility to be thread safe.
2123 Added function, oid_ent_to_oid, to replace the function
2124 oid_getoidbyent, which is not thread safe.
2126 * Added nmem_init and nmem_exit to initialize and release
2127 NMEM resources. Function nmem_init should be called once in the
2128 initial thread before NMEM/ODR is used. statserv.c and client.c
2129 have been changed accordingly. The change was necessary to make
2130 NMEM thread safe. The NMEM memory pool is shared amongst threads
2131 in a process. Unix-based applications will still work fine without
2134 Added NT Services interface for the the Z39.50 (statserv) Server.
2135 Refer to the ztest.c source on the usage.
2137 Windows 95/NT port using MSVC5.0. Project files are included in the
2140 * Defined new 'global' handle for the retrieval (data1) system. The
2141 new handled, data1_handle, describes the state of the data1 system.
2142 This handle is passed as first argument to virtually all
2143 data1 related routines. The functions data1_create and data1_destroy
2144 creates and destroys a data1 handle respectively.
2146 Added ODR encode stream member to all backend request structures
2147 init, search, scan etc. This stream should be used to allocate all
2148 memory used for the response when thread safe operation is needed.
2150 Changed the comstack utility, cs_addstr, to be thread safe. The
2151 returned hostname string returned by the function is now part the
2154 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2155 function. The cs_straddr takes a COMSTACK handle as argument, so this
2156 function must be used after cs_create and before bind/connect.
2157 This function is thread safe.
2159 Moved test server to 'ztest' directory - generic server code still
2160 in 'server' directory.
2162 Made prefix query (pquery.c) utility thread safe.
2164 Added new function modifier YAZ_EXPORT to 'export' public DLL
2165 functions when using windows (see include/yconfig.h).
2167 Added definitions to the OID database (util/oid.c) (RVDM).
2169 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2171 Added call to ccl_rpn_delete in client program.
2173 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2174 release of RPN structure.
2176 Added support for C++, headers uses extern "C" for public definitions.
2177 With input from RVDM.
2179 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2180 Thanks to Ronald van der Meer (RVDM).
2182 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2184 Added support for private extensions to the OID database
2185 (oid_setprivateoids()). Thanks to RVDM.
2187 Added optional, physical ANY (key replication)
2189 Fixed null-reference problem in GRS-1 output filter.
2191 Proximity operator added to Prefix Query Format (PQF).
2193 In test client command "base" accepts multiple databases.
2195 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2199 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2201 Smallish bug-fixes in the new encoders/decoders (explain).
2203 Bug fixed in DeleteRequest.
2205 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2207 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2209 Added SOIF syntax (using private OID for now) to retrieval module and client.
2211 Added Update extended service.
2213 Added SearchResult-1 additional info structure.
2215 Added optional CCL (ISO8777) interpreter as separate module. Available
2218 --- 1.2 1996/6/10 (1st anniversary release)
2220 Added Summary record syntax. Lightly tested.
2222 Added OPAC record syntax. Untested.
2224 Added ResourceReport service encoders/decoders. Untested.
2226 Fixed bug in z_Unit - wrong tagging on unitSystem.
2228 Fixed bug in the DiagRecs decoder.
2230 Added options for max PDU size and session timeout to frontend-server.
2232 Added documentation of query-language parsers and other supporting utilities.
2234 [frontend-server] Added Attribute set to the bend_scanrequest API.
2236 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2237 surrogate diagnostics were generated.
2239 [retrieval] Allow multiple local values for attribute.
2241 [retrieval] Allow multiple attributes per element in .abs files. index type.
2243 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2245 --- 1.1pl2 1996/4/10
2247 Minor changes, mostly specific to Zebra's requirements (retrieval)
2251 Repaired bug in frontend server when running multiple listening
2252 endpoints in dynamic mode.
2254 z_External() now won't break if a known, ASN.1 value comes encapsulated
2255 in an octet-string. The value will pass through unmodified in an Odr_oct.
2257 Added a bit of code to the demo client to decode & display
2258 ASN.1-structured records represented in the octet-aligned branch of
2259 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2261 Added z_ext_getentbyref() to the ASN module. Doc updated.
2263 * Completed the SCAN definition in the ASN module. This may break SCAN
2264 code based on older YAZ-versions at compile-time. The fix is easy -
2267 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2268 under the SCAN definition. Remember to initialize this, server-people.
2270 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2271 that this does not extend to ODR and ASN.
2273 Comstack allows insertion of established socket (primarily for
2274 inetd-operation of servers). Doc updated.
2276 Front-end server can now start from the inetd in TCP mode. Doc
2279 --- 1.0pl4 1996/1/24
2283 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2284 the rank and record number.
2286 Adjustments to the frontend server.
2288 Fixed diagnostic BER dumper. It ignored the file argument.
2292 Various changes to retrieval module.
2294 Changed the union discriminators of the protocol files from enums to
2295 ints paired with #defines.
2297 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2300 *Changed operator in the RPN structure to 'roperator', again to avoid a
2303 Fixed problems in Explain decoders/encoders.
2305 --- 1.0pl2 1995/12/6
2307 Memory bug in log module fixed.
2309 --- 1.0pl1 1995/12/5
2311 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2313 Bug in Explain DatabaseInfo module fixed.
2315 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2319 The shift to v1.0 signals that we now consider the *core* functionality
2320 of YAZ reasonably stable (the core being more or less equivalent to
2321 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2322 tested (Explain not at all - though that will happen soonish).
2324 Minor changes to code to support Windows port.
2326 Various minor changes after we're getting to use GRS-1 & co. more.
2328 Added Espec-1 format.
2330 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2331 of the protocol and it cannot be selected when encoding (maps into 'string'
2332 when decoding). Needed to talk to some servers.
2334 Demo client can request simple element set names.
2336 Added Diagnostic Format encoders/decoders.
2338 Added simple Close handling to frontend server (no hooks for resource
2339 reporting yet), and demonstration client.
2341 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2343 --- 1.0b3 1995/08/24
2345 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2346 handled incorrectly when records were requested in the searchResponse. This
2347 will only affect you if you use the frontend-server.
2349 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2350 Test-client will ask for and print GRS1. Ztest will return dummy records
2353 Added Explain encoders/decoders to the service-level API. Untested.
2355 Added Extended Services: Item Order encoders and decoders to the Service-
2356 level API. Untested. We could use a recent copy of the pertinent bits
2357 of the ILL protocol to add those bits.
2359 Added diagnostic format 1 encoders/decoders to the service-level API.
2362 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2363 odr_cons.c, which causes a more correct output.
2365 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2366 was always set to 0 when no records were requested in the searchRequest.
2368 * Added better external-handling. This shouldn't harm old code that
2369 *encodes* externals. It can break code that looks for a
2370 'single-ASN1-type' representation, since those types that are known
2371 are now decoded immediately. Look at the SUTRS sample code in
2372 seshigh.c and client.c. Documentation updated.
2374 Handling of structured records in bend_fetchresponse. Length -1 marks
2375 structured record, type is deduced from format field.
2377 --- 1.0b2 1995/06/27
2378 Fairly quick maintenance release to add SUTRS support.
2380 Fixed handling of SUTRS records in the demonstration client.
2382 * Added format field to the bend_fetchrequest and bend_fetchresponce
2383 structures of the backend API (frontend server). When the record is
2384 returned, the value of the format field is mapped to an OID. The
2385 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2386 of the record. The special value VAL_NONE in the bend_request means
2387 that no specific format was requested by the client. Documentation
2388 updated accordingly. Test server (ztest) will return a fixed dummy
2389 SUTRS record if your client requests SUTRS.
2391 Documentation updated accordingly.
2393 You can now set external libraries and RANLIB support in the top-level
2397 First public release.
