1 Added facility for sending arbitrary records (ASN.1 any) using
2 ZOOM C's Extended service update. Patch by Sam Reynolds.
6 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
10 Fixed memory violation that could occur when decoding UTF-8. This bug
11 was only present in 3.0.30 of YAZ.
15 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
16 GNU TLS is used by default (if found).
18 yaz-ztest returns OPAC records if a client asks for OPAC.
20 Improved speed of MARC-8 encoding.
22 Added support for lossy and loss-less MARC-8 encoding.
24 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
26 Added new Windows Service wrapper (sc).
28 yaz-client's itemorder command may now send a file.
30 Fixed yaz-marcdump to allow the use of NS prefix for record element.
32 Added new function yaz_log_xml_errors.
34 Allow (but warn) unknown XML attributes in MARCXML parsing.
36 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
38 The UTF-8 to MARC-8 conversion now uses a different set of characters
39 for Greek symbols. Bug #2120.
43 Added yaz_daemon (daemon.h).
45 Fixed bug #2068: pkg-config trouble
47 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
51 Document --with-xml2 option.
53 Added OPAC XML XSD (etc/opacxml.xsd).
55 Allow glob mask for name attribute in retrieval element for the
56 generic frontend server's retrieval facility.
58 Changed yaz_poll_poll to return yaz_poll_except for all returned events
59 except POLLIN/POLLOUT.
61 Fixed error handling in cs_listen. Bug #2037.
65 Fixed version in yaz/yaz-version.h.
67 Fixed bug #2027: Crash when closing connection.
69 Changed configure so that ICU support is only enabled if only ICU
70 and Libxml2 is available (because the ICU chain is XML based).
74 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
75 is built. Only this DLL depends on the ICU runtime.
77 yaz-ziffy is no longer part of YAZ. It is distributed separately by
78 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
80 Changed license of CCL module to 'Revised BSD'. After consultation with
81 remaining members of the original EUROPAGATE consortium, we are re-issuing
82 the CCL module without a separate license. The software was developed by
83 Index Data as part of a research project. The special license was included
84 to help feed usage information back to the project consortium to support
85 project evaluation. At this time, the project consortium has long-since
86 disbanded, and the majority of the original principals have retired. At the
87 same time, we have significantly modified the software during the following
88 years, to the point where very practically no original code remains. To
89 simplify re-use of the software, we have contacted those members of the
90 consortium who could be reached, and agreed to re-issue the module as a
91 proper part of the YAZ package.
93 Tcl scripts uses /usr/bin/tclsh as preferred shell.
95 CQL closer to being version 1.2 compliant. CQL also allows free-form
96 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
99 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
100 bug could make Extended services handling crash in the ZOOM layer. This
101 bug was only present in YAZ 3.0.18.
103 --- 3.0.18 2007/12/19
105 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
108 yaz-marcdump reads and writes collection wrapped records.
110 Handle OPAC for record conversion module.
112 Fixes for ICU wrapper.
114 Allow ICU libs to be controlled with --with-icu .
116 --- 3.0.16 2007/11/12
118 Added yaz_poll which is a wrapper for select/poll. When poll is available
119 and non-buggy, it is used, by yaz_poll . This allows more than 1024
120 sockets to be in use.
122 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
123 functionality through an XML based configuration (ICU chain). This system
124 is useful for search facilities such as Pazpar2 and Zebra that needs to
125 perform tokenization of indexed material. The ICU code in a separate
126 library libyaz3_icu.a.
128 Added HTTP tunnel facility for COMSTACK, bug #1752.
129 This is a facility that allows a Web proxy, such as squid, to tunnel
130 Z39.50 traffic. This facility is "transparent" to must applications
131 using YAZ. It's enabled by using pseudo transport connect: followed by
132 the proxy address, followed by command, then follwed by he regular
133 "virtual" addresss. For example,
134 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
136 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
138 --- 3.0.14 2007/09/21
140 Fixed bad memory reference in ZOOM_record - cuased by member not being
141 initialized. This was a problem only in YAZ 3.0.12.
143 Fixed bug in conversion from MARC to XML: Non-XML characters in control
144 fields were not removed.
146 Changed the way C code is generated from codetables.xml. Made a MARC-8
147 conversion trie for each characterSet section rather than codeTable.
148 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
149 of codetables.xml from Larry Dixson, LOC. Bug #1464.
151 --- 3.0.12 2007/09/12
153 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
154 from ZOOM_record_error).
156 ZOOM C function ZOOM_record_get returns record schema for type="schema".
158 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
160 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
162 Better SRW-to-Bib-1 diagnostic mapping.
164 ZOOM C and yaz-client announces SRU version 1.2 by default.
166 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
169 Fixed in yaz_sru_decode to allow other version than 1.1.
171 --- 3.0.10 2007/08/22
173 Added support for SRU scan for ZOOM.
175 Added support for the use of the older versions or Extended Service
176 Update in ZOOM. To faciliate this, an option "updateVersion" may be
177 set to the version , 1=first, 2=second, 3=third. The third version is
178 what ZOOM C has used so far. And that, obviously, is the default.
180 Added support for CCL queries in Z39.50 queries sent to the GFS (and
181 therefore in Zebra and in SimpleServer-based applications). The new
182 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
183 qualifier file used to transform incoming CCL queries into Type-1 RPN,
184 which is passed into the back-end search callback function.
186 Added support for HTTP Basic authentication in clients: the SRU/W
187 codec encodes the username/password elements of the PDU structure
188 appropriately, and these may be set using the "user" and "password"
189 options in ZOOM-C applications (the same options that are used for
190 Z39.50 authentication).
194 Fixed bug #1208: SSL appears to be broken in ZOOM.
196 Fixed bug #1206: Libxml2 include path weirdness.
198 Added oid_name_to_dotstring.
200 Allow elementSetName to be specified for ZOOM C record update.
202 Allow waitAction to be specified for ZOOM C based for Extended Services.
204 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
205 syntax OID. Bug introduced in YAZ 3 series.
207 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
211 Fixed bug #1157: yaz-client does not read .yazclientrc from current
212 directory. yaz-client now reads commands from file given by option -f
213 if specified; then tries to read .yazclientrc in current directory.
214 Failing that, it reads .yazclientrc from user's home directory.
216 Added support for correlationInfo Note and ID for Record Update via
219 Added yaz-client command querycharset which specifies character set for
220 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
221 (termListAndStartPoint).
223 Charset ISO5428:1984 is an alias for ISO5428-1984.
225 Implemented a way to perform scan in a result set using Z39.50. This
226 is achieved by attaching the result set name in the characterInfo
227 (type InternationalString) of OtherInformation in the Scan Request PDU.
228 The result set is identified in the otherinformation by the new OID:
229 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
230 This allows for scan in result set and faceted search . Zebra did some
231 of this in the APT term using attribute type 8 and value being result
232 set. Using the OtherInformation approach for this is cleaner and easier
233 to work with in proxies and the like. This facility can be used in
234 yaz-client using new command setscan which takes a result set as first
235 argument, start position (APT) as second.
237 Changed decoding of SRU XML packed records to deal with servers that
238 have recordData with XML data with multiple root nodes. Also make
239 comparison for recordPacking case insensitive. Again, one server
240 returns "XML" where others return "xml".
242 For SRU responses allow Content-Type application/xml as well as text/xml.
246 Fixed bug in character set conversion of BER strings. Bug introduced
251 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
253 For OID class, use oid_class consistently.
255 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
258 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
259 character set for bibliographic information interchange". By Giannis Kosmas.
261 Added documentation on new OID API.
265 Changes to generic frontend server interface: added new member
266 'query_charset' for bend_initrequest structure. A backend init handler
267 should set this member to its native character set for query terms.
268 When defined, the frontend server logic will announce this character set
269 to a client if the negotiationModel bit is set by the client. All server
270 implementors are encouraged to specify this. If a backend server does not
271 specify this a warning is issued using yaz_log(YLOG_WARN,..).
273 Added CCL utility to remove terms (stop words) from resulting RPN
274 tree. This is handled by functions with prefix ccl_stop_words_ .
276 New ZOOM C option, "rpnCharset", which allows client-side conversion of
277 terms in RPN queries.
279 Clean-up the CCL API. Moved some internal structures from ccl.h to
280 private header cclp.h. Changed ccl_parser_create so that a Bibset must
281 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
282 This is replaced by ccl_parser_find_str which takes a string instead.
284 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
285 libyaz.la is the core of YAZ except the generic frontend server and
286 does not depend on POSIX threads anymore. libyaz_server.la is the
287 generic frontend server facilities and uses POSIX thread functionality
288 if available. The libyaz.la no longer depends on POSIX threads because
289 the number of global structures is limited. NMEM no longer re-uses blocks
290 between threads ; it simply free's memory immediately but allocates in
291 "large" chunks as usual. We don't expect any performance penalties
292 because of this. The yaz_log system is still using a global log_level so
293 caution must be taken when modifying it with yaz_log_init_.. +
294 yaz_log_mask_str. This, however, should not cause any trouble because
295 these functions are called during initialization of application code
296 anyway. `yaz-config --libs server` returns libs for server applications;
297 `yaz-config --libs` returns libs for non-server applications.
299 New OID database - with public definitions in oid_db.h. Removed old OID
300 database including the head oid.h and definitions such as enum oid_value
301 and struct oident. The new OID database uses the same string names as
302 before but the 'protocol' is gone. There are now only two representations
303 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
304 converts from string to OID; functions with prefix yaz_oid_to_string
305 converts the other way.
307 Change to emit_term() in CQL-to-PQF query translation: when a term has
308 the /regexp relation modifier, do not process it for leading and
309 trailing "^" and "*", which have quite different meanings in regular
312 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
313 write handlers no longer carries a 'last' parameter. This will make
314 yaz_iconv flush "less" characters. A flush is performed by call to
315 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
317 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
318 removed, because function yaz_query_to_wrbuf does the same.
320 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
321 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
323 Deprecated MARC utility functions removed.
325 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
328 Branch split: YAZ_2_1_55_branch
330 --- 2.1.54 2007/03/16
332 Fix to ZOOM-C so that transparent reconnection is properly handled on
333 connections that are in asynchronous mode.
335 Fixed compilation on OpenBSD 4.0.
337 Large strings in GRS-1 records are now properly displayed in yaz-client.
339 Added character conversion support for "advancegreek"; based on patch from
342 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
343 sequence is met. Before the error was not set so it would be unknown.
345 Adjust yaz-marcdump MARC reader so that it skips until record separator
348 --- 2.1.52 2007/03/07
350 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
351 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
352 fd_set structure used as a bitmask for the FDs to be selected on.
354 Using ACX_PTHREAD macro to check for POSIX threads.
356 Fixed have-vsnprintf check.
358 --- 2.1.50 2007/02/23
360 Fixes for configure on BSD. Bug #900.
362 Added snprintf/vsnprintf wrappers for systems that don't have
363 limits (heavens forbid).
365 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
366 created before all previous tasks were completed and removed from the
367 task queue, the new task could be removed by a mistake.
369 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
371 Implemented pass-through CQL-to-PQF conversions. Bug #861.
373 Fixed bug #832: Problem with MARC/charset in yaz-client.
375 Fixed bug #668: save command line history for yaz-client.
377 Fixed bug #830: pkg-config support.
379 --- 2.1.48 2007/01/23
381 Extended ZOOM result set options with two options that may be read by
382 a client: resultSetStatus and presentStatus with values as specified for
384 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
386 Fixed bug #827: Using SSL fails on Debian etch.
388 Fixed bug #826: Weird looking chars for set of MARC records.
390 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
391 that is treated as an ItemOrder with itemRequest being an XML document
392 external. The value of "doc" is the content.
394 Extended the GFS search facility. New member of bend_search_rr
395 'estimated_hit_count' signals that hits is known to be an estmate
396 (higher or lower than real hit count). New member 'partial_resultset'
397 signals that the search was partial (hit count is lower or equal than
398 real hit count). For Z39.50, the information is stored in resultSetStatus
399 member of SearchResponse APDU. For SRU, the information is signalled
400 via SRU diagnostic 59: "Result set created with valid partial results
403 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
405 --- 2.1.46 2007/01/13
407 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
409 Added ZOOM_connection_peek_event.
411 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
412 the following new functions:
413 ZOOM_event_nonblock, ZOOM_connection_process,
414 ZOOM_connection_get_{socket,mask,timeout},
415 ZOOM_connection_fire_event_{timeout,socket}.
416 The existing blocking event handler, ZOOM_event, is a wrapper for the
417 + blocking ZOOM_event_sys_{poll,select}.
419 Implemented function ccl_xml_config which parses XML version of CCL
420 configuration (bug #798).
422 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
424 Added timings utility (yaz/timing.h)
426 --- 2.1.44 2007/01/03
428 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
431 Fixed bug #779: Rotation of apdu.log fails.
433 Fixed for character set conversions:
434 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
435 Honor G1 set in MARC-8 decoding.
437 --- 2.1.42 2006/12/17
439 Fixed bug #775: char conversion does not handle Alternative UTF-8
442 Implemented function yaz_marc_read_line which parses MARC line format
443 records. There is a wealth of formats out there. So far, this function
444 reads line records produced by yaz_marc_write_line.
446 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
447 more generic and easier to remember(!) options: -i format and -o format
448 which specifies input format and output format respectively - where
449 format is one of "marc", "marcxml", "line", "marcxchange".
451 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
452 does not print anything except warnings for records.
454 For yaz-marcdump, added support for MARC split into files (-s) with a given
457 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
458 spec, at http://www.loc.gov/standards/sru/record-update/
459 This has changed the binary layout of the following structs:
460 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
461 bend_update_rr . Patch by Ko van der Sloot.
463 Added GFS utility function bend_assoc_is_alive which returns 1 if
464 association is still alive (client is connected); 0 otherwise (client
465 closed connection). This allows busy servers to stop working for
468 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
469 been a separate piece of software. This version of ziffy has been modified
470 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
472 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
474 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
475 Client code may now interrogate options such as "init_opt_sort" to
476 find out whether the server claims to support various options.
478 --- 2.1.40 2006/11/27
480 Added utilities yaz_{set,get}_esn to set/get element set name from
483 Removed the build of libyazthread.la. The libyaz.so is the threaded version
484 of YAZ and has been so since YAZ 2.1.10.
486 Implemented ZOOM_record_error which returns error information for
487 record (surrogate diagnostic).
489 --- 2.1.38 2006/10/31
491 Updates for SRU Update by Ko van der Sloot:
492 1. Changed name from "operation" to "action"
493 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
494 versions in the code, marked as 'backward compatible'.
495 3. Added diagnostics for SRU Update.
497 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
499 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
501 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
503 For GFS, fixed problem with SRU diagnostic 'First record position out of
504 range' being issued for 0 hits.
506 zoomtst10 part of Windows Build.
508 --- 2.1.36 2006/10/13
510 Implemented yaz_filepath_comp which splits a path into file path
511 components (required by Zebra 2.0.3+).
513 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
514 BSD inspired license until now so this should not have any real impact on
515 anybody. See http://www.opensource.org/licenses/bsd-license.php
517 Fixed bug #687: Missing log lines.
519 Fixed bug #678: CQL to PQF translation does not preserve double-quote
522 Fixed bug #689: SRU diagnostics to be added.
524 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
525 whether a connection is idle (no more work do do).
527 --- 2.1.34 2006/10/04
529 Change type of optval from long to int for invocation of setsockopt with
530 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
532 Added support for specifying the max log file size for the Generic
533 Frontend Server. The size is given with option -r.
535 --- 2.1.32 2006/09/21
537 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
539 --- 2.1.30 2006/09/17
541 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
544 Fixed bug in Generic Frontend Server that could cause a server to stop
545 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
547 For the generic frontend server, the maximum record size is used as maximum
548 size of incoming packages (SRU + Z39.50). The value until was previously
549 only used in Z39.50 Init negotiation and, later, in a session controlled
550 sizes of records returned. This is controlled using -k option. It can be
551 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
553 --- 2.1.28 2006/09/04
555 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
558 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
560 New option for yaz-marcdump -lpos=value which allows setting a portion
561 of MARC header to a certain value.
563 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
565 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
566 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
568 --- 2.1.26 2006/08/15
570 Fixed problem with SRU mode type (soap, get, post) for yaz-client
573 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
575 --- 2.1.24 2006/08/08
577 Fixed MARC ISO2709 encoding routines to deal with character set
580 Minor changes to GFS logging. Database included in search request log
583 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
584 cached/multiple records.
586 Shared libraries are built by default on Unix+configure.
588 Changed cql2pqf transformation to use a different evaluation order. The
589 new order is: always, relation, structure, position, truncation, index
590 and relationModifier. Old order was: always, relation, relationModifier,
591 structure, index, position, truncation. Note that the the latter ones
592 override former ones for identical attributes.. The new scheme means that
593 it is possible to override any existing attribute with a relationModifier.
594 And also that it is possible to override everything for the index rule
595 (except the ones listed in relationModifier). No order is perfect but this
596 one, we believe, covers more real cases.. The "always" should have been
597 called "default", since the attributes there can be overridden with all
600 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
601 compilation phase, but also for yaz-config --cflags output. This allows
602 us to have public headers with Libxml2 stuff in them . It should also,
603 eventually, make Libxml2 checks redundant in packages using YAZ, such
606 --- 2.1.22 2006/06/15
608 Changed SRU update structure bend_update_rr so that SRU diagnostics are
609 stored in uri, message and details.. Previously diagnostics were stored
610 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
611 compatibility.. but he's probably the only one affected, so.
613 Added support for CCL, compiled on the client side, in ZOOM-C. This
614 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
615 input; the resulting query objects can be used for for searching with
616 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
618 YAZ' configure searches for OpenSSL by default.
620 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
621 SL_CTX_use_certificate_file. See

623 for more info. Thanks to Ko van der Sloot.
625 --- 2.1.20 2006/06/02
627 Bug #600: SRU GET, POST support for yaz-client. Introduced
628 command 'sru' which selects method SOAP/GET/POST.
630 Allow missingValueAction to be specified for the sortspec string -
631 function yaz_sort_spec. By default, the missing value action is null.
632 Use ! to specify "abort". Use = followed by stringvalue to specify default
635 Ensured that Present-handler (if defined) is called in GFS before any call to
636 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
637 searchRetrieve requests.
639 Documentation for YAZ is now based on the Docbook XML/XSLT using
640 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
641 is no longer depending on jade/openjade or docbook-to-man scripts.
642 PDF is no longer part of the distribution - but can optionally be
643 made using DSSSL/jadetex or FOP.
645 Added retrieval handling support in Generic Frontend Server to support
646 conversion between MARC/XML as well as XSLTtransforms. See
647 etc/yazgfs.xml for an example.
649 Added Authentication support to Generic Frontend Server in SRU
650 mode. Authentication using HTTP Basic is supported, as is the use
651 of 'x-username' and 'x-password' parameters in the request itself.
653 Added support for a new character set MARC8s identical to MARC8 except
654 that it converts combined characters to single Unicode characters in the
655 Latin-1 range (when possible).
657 --- 2.1.18 2006/04/24
659 ASN.1 compiler 0.4: generates brief Doxygen file header for
660 generated .h/.c files.
662 Utility yaz_iconv now supports conversion to MARC-8.
664 New facilities for the MARC module. The reading - and writing of
665 content are separate methods for the yaz_marc_t handle. The following
666 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
667 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
668 format). Write functions have prefix yaz_marc_write_.. The existing
669 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
670 available. Removed support for OAI-MARC and simplexml (not the
671 simplexml from PHP5).
673 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
674 to be returned for this connection.
676 --- 2.1.16 2006/03/31
678 Allow multiple languages and charsets to be specified with
679 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
680 negcharset iso-8859-1,utf-8
682 Translation of proximity nodes from CQL into PQF now works.
684 Moved to automake 1.8, 1.9.
686 Added function yaz_log_set_handler which allows a log handler to be
687 installed. This handler will be called for all log messages. Output
688 to file is also produced; but that can be disabled by passing NULL
689 fname to yaz_log_init_file.
691 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
693 For SRW (including GFS), accept application/soap+xml as content-type
696 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
697 produces NO stylesheet reference even if a default stylesheet is specified
700 --- 2.1.14 2006/03/14
702 Updated Windows package to include yazd.dll + yazd.lib for the
703 Development component.
705 If the environment variable YAZ_LOG is set, then it is used as a
706 string indicating the default level of logging to use if not
707 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
708 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
709 used as before. So, for example, to omit warnings from YAZ logging,
712 cql_transform() now map structure and other attributes before indexes,
713 so that index-specific structures and other attributes can override
714 defaults. So now a combination of mapping specifications such as:
716 index.dc.date = 1=date-modified 4=5
717 does the right thing.
719 cql_transform() now also respects the "always" mapping specification,
720 which establishes an initial set of attributes to be used for all
721 terms except where overridden by more specific attributes associated
722 with the index, relation or modifier.
724 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
725 which mode to use; one of "post", "get" or "soap" (SRW, default).
727 Fixes for yaz_iconv routines: changed trie-based character set conversions
728 to use only non-negative values for bit fields due to Sun's C compiler not
729 supporting negative values.
731 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
732 sequences where not read correctly. Fix by Rustam Usmanov.
734 Updated win/makefile to use options, settings which makes things
735 compile with VS C 2005.
737 --- 2.1.12 2006/02/01
739 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
741 In ZOOM socket code, use select instead of poll on MacOSX.
743 ZOOM-C now support client-side compilation of CQL into RPN that is
744 sent to the server, enabling CQL to be used against all Z39.50
745 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
746 ZOOM_query object, and submit it using ZOOM_connection_search().
747 The CQL-to-RPN translation uses a configuration file, the name of
748 which must be specified in the Connection's "cqlfile" option.
750 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
751 function, which takes as its start-term parameter a ZOOM_query object
752 (which may have had either CQL or RPN set into it).
755 --- 2.1.10 2005/11/29
757 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
758 GFS to support this as well. Backend handler, bend_srw_update, does the
759 update work. Code contributed by Ko van der Sloot.
761 Allow retrieval of Search Result-1 information in ZOOM by the use of
762 options that are attached to a result set. ZOOM documentation updated
765 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
766 UTF-8 conversion. Patch by Raj Patel.
768 Added option -m to GFS to control formatting of timestamps in log file.
770 Added 'exit' as synonym for 'quit' in yaz-client
772 Added support for specifying SRW resultSetId + resultSetIdleTime in a
773 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
774 for the new members. Patch by Ko van der Sloot.
776 Added support for SRU POST. It is supported for content-type
777 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
779 Do not build the separate Multi-threaded (MT) library libyazthread.la.
780 Instead make the library libyaz.la multi-threaded. Threading as a whole
781 can still be disabled by configure option --disable-threads. Previosly,
782 with older GLIBCs there were problems with MT libs under Apache. This
783 has now been fixed a long time ago.
785 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
788 CQL module modified to be case insensitive for relations/indexes/operations.
790 Fixed bug in CQL transform code: incorrect value relationModifieder
793 Added 'show all' command for yaz-client which retrieves all results
796 Added new yaz-client, xmles, which takes a (private) OID and
797 a document to be sent as an extended service request.
799 Describe new yaz-client commands wait_response and set_auto_wait.
801 Increase TCP/IP listener backlog from 3 (which I am guessing was
802 copied from the SunOS manual entry way back when) so SOMAXCONN, so
803 that the socket will queue as many incoming connections as it's able
804 to handle ongoing connections. In other words, it will never now
805 refuse a connection that it would be able to handle merely because
806 it's not got around to accepting() enough of the pending connections
807 yet. This is the behaviour anyway under Linux, where the listen()
808 argument is ignored; but not under BSD and on systems such as
809 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
810 YAZ-based servers should now be uniform across operating systems in
813 yaz-marcdump uses 64-bit file access on some systems. This is enabled
814 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
815 This allows yaz-marcdump to read large MARC batches (>2 GB).
817 Modified all YAZ source files - except the source which is auto-generated
818 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
821 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
822 corresponding to the existing *_setl() function. These allow option
823 values containing arbitrary valuues.
825 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
826 ZOOM_resultset_sort() in new applications. Its behaviour is identical
827 except that it returns an indicator of whether or not the sort
828 criterion was accepted (0 for OK, -1 for invalid).
832 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
833 MARC output rather than returning "new" buffer.
835 yaz-client warns about unknown init options.
837 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
841 Added support for SRW sort in Generic Frontend Server. Patch
842 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
843 sortKeys - or NULL if none is provided.
845 Fixed bug #307: It was impossible to specify indefinite/no timeout
846 for ZOOM_event. Special timeout value -1 now means indefinite timeout
849 Added support for multiple languages and charsets to be specified in
850 ZOOM. Each charset/language is separated by a blank. If negotiation is
851 in effect in init-response, Option
852 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
853 Code based on patch by Vasiliy Osadchuk.
855 Fixed bug #306: infinite recursion that occurred when calling
856 yaz_log_level_init as the first call (before other log level or
859 Fixed bug in scan handling in front end server: if preferred-Position-In-
860 Response was non-present, a NULL pointer referece was performed.
864 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
865 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
866 now defined for all those error codes. So instead of putting 109 in
867 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
868 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
870 Modified the yaz-marcdump utility to skip garbage bytes between MARC
873 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
875 Program yaz-client now exits and produces an error message if multiple
876 Z39.50 servers are specified on the command line (none or one allowed
879 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
884 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
886 Fixed bug #272: Preserve spacing for CCL terms.
890 Added support for virtual hosts and multiple backend servers for
891 the YAZ frontend server. The configution is XML based and
892 support specificition of CQL to RPN mappings and explain information.
893 See section "Virtual Hosts" in the YAZ manual.
895 Extended OPAC display utility. OPAC display utility renders
896 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
897 to supplement yaz_marc_decode_wrbuf.
899 Fixed a bug in MARC decoder that could caused it to crash for some
900 invalid MARC records. More diagnostics and warnings where added in
901 XML output (warnings, etc are stored in comments).
903 --- 2.0.34 2005/02/08
905 Fixes for UNIX domain sockets. Bug #261.
907 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
909 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
910 Added yaz_marc_subfield_str which defines subfield lead string which is
911 used in YAZ_MARC_LINE format. Default string is blank+$. Added
912 yaz_marc_endline_str which defines end of fields string used in
913 YAZ_MARC_LINE format. Default string is newline.
915 Experimental support for MarcXChange. This format can be produced
916 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
917 http://www.bs.dk/standards/MarcXchange.xsd
919 Added yaz-client commands scansize that sets maximum number of
920 entries to be returned by scan.
922 --- 2.0.32 2005/01/11
924 Added support for SRW scan in yaz-client and Generic Frontend Server.
926 * Added whereInList member to SRW Scan Term.
928 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
930 Fixed NMEM system to return aligned blocks on the smallest boundaries
931 that are suitably aligned for all possible types on the particular
932 architecture YAZ is being built for.
934 --- 2.0.30 2005/01/04
936 Fixed numerious warnings that was issued with newer versions of GCC.
938 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
939 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
942 Make YAZ Generic Frontend Server slightly faster.
944 Enhance (and reduce) logging for Generic Frontend Server.
946 Revert YAZ log system so that it flushes every write operation
947 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
949 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
950 instead of LOG_, due to name clash with syslog(3). LOG_ are still
951 present. New applications should define YAZ_USE_NEW_LOG=1 - this
952 will effectively disable old definitions.
954 --- 2.0.28 2004/11/09
956 Added yaz_log_time_format which specifies log format using
959 Added yaz_log_module_level which returns mask for a module. Value
960 is non-zero mask a if module is enabled; zero if disabled.
962 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
963 in include/yaz/cql.h.
965 Fixed bug #176: Dont throw diagnostics on empty SRU args.
967 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
969 Fixed bug #172: RPM builds does not enable SSL.
971 Doxyfile.in part of dist. Doxyfile generated by configure.
973 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
974 are given and the corresponding component does not exist.
976 Extend CCL documentation in YAZ reference. Describe r=r.
978 --- 2.0.26 2004/10/01
980 Fixed MARC->MARCXML conversion to properly deal with
981 fields, subfields, indicators having non-ASCII characters.
983 Fixed MARC->MARCXML conversion so that ASCII control characters
984 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
987 Added YAZ GFS support for conversion from Z39.50 surrogate
988 diagnostics to SRW surrogate diagnostics.
990 Bug fix: YAZ GFS did not return schema in explainResponse.
992 --- 2.0.25 2004/09/30
994 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
995 now converts recordSchema to elementSetName as well as schema URI.
997 Fixed bug in COMSTACK that prevented HTTP request packages from being
1000 --- 2.0.24 2004/09/29
1002 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1003 does not require white-space before and after the dash in a range, e.g.
1004 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1007 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1008 due to new GCC removing "redundant" code.
1010 Added yaz-client commands scanpos and scanstep that sets preferred
1011 position and step-size for scan.
1013 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1015 Added CCL utility ccl_qual_buf which parses one or more CCL
1016 spec lines in a buffer.
1018 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1019 of name and value - ignoring empty lines and comments.
1021 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1023 Added odr_get_element_path which returns current element path for an
1024 ODR handle. This utility is useful in error handling or user-defined
1027 Added ODR_PRINT utility odr_set_stream which is is a more generic
1028 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1029 to a write function and pointer to close function. The close function - if
1030 non-NULL - will be called during odr_destroy.
1032 Fixed bug in CCL parser where truncation char was not removed from
1033 right side when truncation=both was in effect.
1035 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1038 --- 2.0.23 2004/08/11
1040 Fix buffer overrun in CQL parser when dealing with proximity (%).
1042 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1043 to UTF-8/UCS conversion is now only based on codetables.xml.
1045 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1047 --- 2.0.22 2004/08/06
1049 Add support for more "commit changes" in ZOOM (uses Extended Services).
1051 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1054 Yet another small fix for configure of SSL.
1056 --- 2.0.21 2004/05/14
1058 Fix SSL libs for configure when --with-openssl=DIR is given.
1060 --- 2.0.20 2004/05/10
1062 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1064 SSL comstack now uses yaz.pem certificate file on server side
1065 by default. Certificate filename can be configured by calling
1066 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1068 Fix bug regarding multiple calls to ZOOM_connection_connect.
1070 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1072 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1073 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1075 ZOOM now allows inspection of X509 peer certificate for verification.
1076 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1078 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1079 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1080 as "modular" but it simplifies things.
1082 Added cs_get_peer_certificate to that returns peer X509 PEM.
1084 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1085 NULL if SSL is unavailable.
1087 Documentation about MARC decoding tools.
1089 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1091 --- 2.0.19 2004/03/30
1093 Rename CHANGELOG to NEWS to follow GNU style packing.
1095 Fix bug with missing initialization of member in init_diagnostics.
1096 This bug affects threaded version of GFS server.
1098 --- 2.0.18 2004/03/20
1100 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1103 Ensure zlib.dll is packed with Windows install.
1105 --- 2.0.17 2004/03/17
1107 Fix encoding of xsd:string to use text instead of CDATA.
1109 Fix endless loop in CQL parser with unbalanced ".
1111 Use a more compact way to store MARC-8 conversion tables.
1113 --- 2.0.16 2004/03/16 Debian only
1115 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1118 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1123 --- 2.0.15 2004/03/01
1125 Another fix for decoding of XML packed records.
1127 --- 2.0.14 2004/02/25
1129 Fixes for Chunked encoding. White space not ignored after length spec.
1131 Update NS and use default NS for SRW diagnostic elements.
1133 --- 2.0.13 2004/02/23
1135 Implement ZOOM_resultset_cache_reset which resets record cache.
1137 Implement ZOOM_resultset_sort which sorts a result set.
1139 Implement chunked HTTP transfer.
1141 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1143 --- 2.0.12 2004/02/16
1145 Added member 'schema' to bend_explain_rr structure so that backend
1146 can specify explain record identifier. Defaults to Zeerex 2.0.
1148 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1150 --- 2.0.11 2004/02/16
1152 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1155 Added init command for yaz-client which sends "extra" init request.
1157 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1158 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1160 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1162 Make ZOOM error code for "invalid query".
1164 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1166 --- 2.0.10 2004/02/05
1168 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1171 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1173 Added option -p <file> to make Generic Frontend Server to write PID file.
1175 Added option -D to put Generic Frontend Server in background on its own.
1177 Make ZOOM C recognize option "password". If unset, "pass" is used
1178 (for backwards compatibility).
1180 Fixed a bug in Generic Frontend Server that could make it crash if a
1181 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1184 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1185 Must be issued before open, in order to be in effect.
1187 --- 2.0.9-6 2004/01/12 Debian/Windows
1189 Make the SRU server more picky WRT unknown params, etc.
1191 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1193 New YAZ client command, options, that sets Z39.50 options.
1195 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1196 options from a string of tokens (one token for each option bit).
1198 Update SRW diagnostic code messages.
1200 --- 2.0.9-5 2004/01/07 Debian/Windows
1202 Handle user defined stylesheet for SRW/SRU.
1204 --- 2.0.9-4 2004/01/06 Debian/Windows
1206 Fix bug in decoding of Content-Length.
1208 --- 2.0.9-3 2004/01/06 Debian/Windows
1210 Fix a bug with decoding of XML packed records.
1212 --- 2.0.9-2 2004/01/05 Debian only
1214 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1216 Fix bug in SRW/SRU diagnostics decoding.
1218 --- 2.0.9 2004/01/05
1220 Fixed bug in Generic Frontend Server which could drop records exceeding
1221 preferred message size. Reported and fixed by Irina Dijour.
1223 Fixed calculation of package size for structured records in Generic
1224 Frontend Server. Reported and fixed by Irina Dijour.
1226 Fixed namespace for SRW/SRU diagnostics.
1228 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1230 --- 2.0.8 2003/12/22
1232 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1233 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1236 CQL changes to reflect recent changes to the specification:
1237 * Documentation talks about context sets instead of index sets.
1238 * Documentation talks about indexes instead of qualifiers.
1239 * The CQL-to-PQF transformer's configuration file now uses
1240 "index.set.name = <attributes>" instead of the old form
1241 "qualifier.set.name = <attributes>". (Both forms are still
1242 understood but the latter is deprecated.)
1243 * CQL terms with no explicit index specified are now interpreted as
1244 cql.serverChoice instead of srw.serverChoice (which of course
1245 behaves exactly the same.)
1247 --- 2.0.7 2003/12/16
1249 MARC conversion can now generate ISO2709 output in another
1250 character set. yaz-marcdump uses this facility if you invoke it
1253 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1254 functions from there can be used from C++.
1256 --- 2.0.6 2003/12/04
1258 Frontend server now transfers memory from decoded packages to stream
1261 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1262 references to show up.
1264 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1265 the ZOOM Abstract API. The older names for the same options are still
1266 also supported for the benefit of old applications.
1268 ZOOM-C supports "implementationId" and "implementationVersion" options
1269 to go along with "implementationName". These allow the user code to
1270 specify identification strings to be sent to servers.
1271 Add OID for the new ExtLite attribute set.
1273 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1274 as requested/supplid by Ere Maijala <ere@atp.fi>
1276 For generic frontend server, reverse the order of
1277 "toolkit-supplied / application-supplied" strings sent as implementationId,
1278 Name and Version. Also, remove the spaces around the slash. This brings
1279 the GFS in line with the behaviour of ZOOM-C on the client side.
1281 Add function ZOOM_scanset_display_term.
1283 yaz-client shows scan displayTerm if present.
1285 Utility yaz-iconv is now installed by default along with the man page
1288 Extend configure check for OpenSSL to use pkg-config where available (such
1291 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1292 server to specify uid/gid/mask for socket using the format
1293 unix:[user=uid,][group=gid,][umask=mask,]file=path
1294 If file= is omitted the existing format is assumed, e.g.
1296 in which case the mask is 0666 (rw for everybody).
1298 Major restructure of YAZ source. All source in libyaz is in src directory.
1299 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1300 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1302 Added man page for utility yaz-marcdump (used to be called marcdump).
1303 yaz-marcdump is installed by 'make install'.
1305 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1306 of incoming package failed.
1308 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1310 Change prototype of odr_perror: add const to message string.
1312 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1314 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1315 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1316 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1317 DNS lookup. There should not be any compatibility problems with this
1318 assuming that blocking=1 or 0 is used.
1320 Fix bad reference in UNIX comstack in function cs_addrstr.
1322 Fix for compilation on AIX.
1324 The generic front-end server (server/seshigh.c) now supports returning
1325 Init diagnostics to the client in User-information-field, in
1326 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1329 --- 2.0.4 2003/09/04
1331 Allow any CQL relation (not just all,any,exact,scr).
1333 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1334 that features the same UI.
1336 Implemented command update0 in YAZ client which is equivalent to
1337 update but uses old of Ext Update ASN.1.
1339 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1340 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1341 Previously no OID was used for this info.
1343 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1344 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1345 returns 'malformed search term' otherwise.
1347 SortResponse member resultCount now set to NULL in sort handler of
1350 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1353 Add three new utility functions for translating OIDs between various
1354 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1355 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1356 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1357 char *oid_to_dotstring(const int *oid, char *oidbuf);
1358 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1360 Reverted modifications for ES Update definition for z_IU0Update
1361 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1362 is back to YAZ 2.0.2.
1364 String value attributes for CCL parser.
1366 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1367 which their FirstSearch server returns in Init responses, sometimes
1368 carrying useful diagnostic information when Init fails. This has the
1369 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1370 "z39.50/oclcui.asn", where its definition is somewhat different from
1371 what OCLC document on their web-site, as required to interoperate with
1374 Support for anonymous authentication in yaz-client. Use the command
1377 * Fix the OID of the Index Data-local "admin" Extended Service from
1378 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1379 the 1000, which indicates a locally-defined OID, was a mistake.
1381 --- 2.0.3 2003/06/20
1383 Fix CCL directive @case handling so that it affects string match for
1384 both CCL keywords and qualifiers.
1386 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1387 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1388 Decoder has been updated with ASN.1 changes as listed in
1389 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1390 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1391 z_IUUpdate, remains unchanged.
1393 ZOOM_record_get may now return a record in a specific character set.
1394 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1395 "from" is the character set of record as returned by target. "to" is
1396 the character set to be returned. If omitted, "to" is UTF-8.
1398 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1400 New ODR utility, odr_getelement, which returns name of element for
1401 which encoding/decoding failed.
1403 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1404 in cases where a required element was omitted.
1406 Bug fix: some MARC8 sequences were not converted.
1408 New ZOOM option "step" which specifies number of records to be
1409 retrieved in one chunk. Used in conjunction with "start" and "count".
1411 SRW support for yaz-client. Use scheme http: to use it, e.g.
1414 yaz-client no longer does (un)intelligent character set conversions
1415 by default. Can be enabled with charset and marc_charset commands.
1417 xmalloc trace fix for 64-bit systems such as DEC alpha.
1419 Solaris 2.6 compile fix.
1421 New function, cql_strerror() translates SRW error codes, as returned
1422 by cql_transform_error(), into human-readable English strings. Used
1423 in yaz-client diagnostics when appropriate.
1425 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1426 converts it into a type-1 query which is sent to the server. This
1427 makes CQL available for use with all Z-servers, as opposed to the tiny
1428 minority that can handle CQL queries themselves.
1430 --- 2.0.2 2003/04/28
1432 New Debian package layout similar to the Redhat Package layout.
1434 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1435 and search result respectively.
1437 --- 2.0.1 2003/04/25
1439 Redhat package is now several packages: libyaz (runtime libraries),
1440 libyaz-devel (development and documentation, and yaz (utility programs).
1441 Package spec file by Morten Bogeskov.
1443 New member 'schema' in struct bend_fetch_rr which the name of requested
1444 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1445 handler MAY set this to reflect the schema of the returned record.
1447 New member 'display_term' in struct scan_entry. GFS now sets member entries
1448 and allocates scan entries to be filled by user scan handler. In previous
1449 version, entries member was allocated by the scan handler. That still works,
1450 but the GFS will ignore member display_term - assuming it was NOT set by
1451 the handler. The fact that the GFS now allocates the entries both allows
1452 for new members and makes a scan handler easier to write.
1454 Fix CQL lex buffer overflow.
1456 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1457 SRU default recordPacking is string.
1459 SRU protocol support for frontend server.
1461 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1463 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1465 Added scan for the ZOOM shell (zoomsh).
1469 * String Identifers for Schemas (Amendment 5).
1470 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1471 Old definition for schema
1472 Odr_oid *schema; /* OPT */
1477 Z_InternationalString *uri;
1478 #define Z_Schema_oid 1
1479 #define Z_Schema_uri 2
1482 * resultCount parameter to Sort Response (Amendment 1).
1483 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1485 Support for SRW 1.0 over HTTP. This is an optional feature and
1486 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1489 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1490 on the same port. SRW SearchRetrieveRequests are mapped
1491 to bend_init,bend_search,bend_fetch,bend_close.
1493 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1495 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1496 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1498 ZOOM connections are SRW based if schem http is used for hostname
1499 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1500 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1502 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1503 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1504 distance=n, order=true/false, relation=le, prox unit=word. If
1505 n is omitted, distance 1 is used.
1507 Fixed problem with C compiler include path in wrong order.
1509 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1510 on Solaris. Patch from Ko van der Sloot.
1512 New MARC decode API. All new functions operate on a yaz_marc_t
1513 handle. The most important new functions are: yaz_marc_create,
1514 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1515 decode and destroy respectively. Decoder can produce formats
1516 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1517 include/yaz/marcdisp.h.
1519 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1520 to UTF-8, UCS-32, wchar_t or Latin-1.
1522 * Prototypes for yaz_iconv_-functions moved to separate header
1523 include/yaz/yaz-iconv.h.
1525 Make a few private functions 'static' in unix.c. This prevents
1526 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1528 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1529 are set when Init Response is received.
1531 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1532 but returns diagnostic set as well.
1534 New function yaz_strerror which is a portable wrapper for
1535 strerror/strerror_r/GetLastMessage.
1537 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1538 is returned for MARC. If type is "oai", then OAI MARC is returned.
1540 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1543 --- 1.9.2 2002/11/26
1545 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1547 Fix bad race conditions on SIGTERM and terminate gracefully in
1550 Move retrieval (data1) module to Zebra since nobody seems to be
1553 Add GRS-1 render for ZOOM using same format as yaz-client.
1555 --- 1.9.1 2002/10/05
1557 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1559 Fix broken ESpec handling in data1 module.
1561 SGML reader parses comments and makes them part of the data1 tree.
1563 Added several type casts so that YAZ compiles as C++ code.
1565 ZOOM didn't handle PDU encoding failures properly.
1567 Added more Bib-1 diagnostics (approved extensions).
1569 GNU configure: better check for iconv.
1571 More portable use of accept, getpeername. Check for socklen_t. Use
1572 int/size_t if socklen_t is not defined.
1576 PQF parser rejects bad queries - including those with extra
1577 characters in them. PQF parser used to silently ignore that.
1578 Cleaner API for PQF added, which allows you to get detailed
1579 error information for bad queries (see yaz/pquery.h).
1581 Fixed bug in ZOOM_record_get for type "database".
1583 Implemented mini iconv library supporting conversions between
1584 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1586 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1588 --- 1.8.9 2002/08/20
1590 Fixed ZOOM C record cache so that preferredRecordSyntax and
1591 elementSetName is used to check for already fetched records.
1593 --- 1.8.8 2002/08/02
1595 Added three members in bend_initrequest structure to facilitate
1596 character set negotiation.
1598 Fixed a bug in frontend server that could cause indefinite
1599 loops under rare conditions.
1601 Revised character set utilities (charneg.h) so that encoding
1602 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1604 For PQF, directive @term <type> sets term type for Scan/Search.
1605 Here <type> is general, string, numeric, null. The term type
1606 is inherited - just like @attr.
1608 New call odr_set_charset that sets character set conversion for
1609 international-strings on a ODR stream. Prototype is:
1610 int odr_set_charset(ODR o, const char *to, const char *from);
1611 The InternationalString is still represented as C string in YAZ
1612 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1613 won't). On the protocol level, you can use any encoding.
1615 Support for UNIX sockets in ZOOM.
1617 Solaris recv sometimes returns errno == ENOENT. It is treated as
1618 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1620 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1621 both client and server. Code by Morten Bogeskov.
1623 --- 1.8.7 2002/05/22
1625 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1626 that they can be used directly from Visual Basic. You must recompile
1627 your windows APP if you're using ZOOM.
1629 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1630 Commands "lang" and "charset" sets language and character set respectively.
1631 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1632 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1634 Attributes from multiple CCL fields may be OR'ed rather than merged
1635 using directive "@field or". Fields are still merged by default -
1636 equivalent to "@field merge".
1638 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1641 Fixed bug in zget for parameter ExtendedServicesResponse.
1645 --- 1.8.6 2002/03/25
1647 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1649 Client displays USR.1:SearchResult-1 (hits per term).
1651 Additional Search Info for search in Generic Frontend Server.
1653 Fixed CCL parsing of "field=s".
1655 WIN32 installer - using the excellent NSIS software from nullsoft.
1657 Fixed CCL parsing of "field = - <number>".
1659 Added function yaz_marc_decode that decodes MARC for line mode
1660 display or XML (similar to that used by JZKit).
1662 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1663 Z39.50. But ISO/ILL was, however.
1665 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1666 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1668 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1669 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1671 --- 1.8.5 2002/02/03
1673 New YAZ client features: Command completion and new commands:
1674 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1675 Code provided by Jacob Poulsen.
1677 New call oid_trav, that visits all registered OIDs via callback.
1679 Function ZOOM_record_get now returns const char pointer rather than
1680 void pointer. It saves a lot of type casts.
1682 For YAZ client, command "auth" now allows you to set authentication
1683 in IdPass style. It is enabled when three tokens are given - order
1684 is user, group and password.
1686 Fix memory leaks in MARC record handling for ZOOM.
1688 New option for YAZ client, -k <kilobytes> that sets
1689 maximum record size. Similar to -k option for generic frontend
1690 server and yaz-ztest.
1692 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1694 Prefix query parser reports "fail" when bad attribute set is given.
1696 Fix in MARC decoder. Proximity logging. Fix for attribute set
1697 in scan handler for server. Patches by Shigeru Ishida.
1699 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1702 Configure option --with-openssl=<dir> now works when a directory is
1703 specified. Patch provided by Morten Bogeskov.
1705 New option for YAZ client, -u <auth>, that sets authentication.
1707 ZOOM fix: error information was sometimes "missing", since error
1708 was cleared/reset too when it shouldn't.
1710 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1712 --- 1.8.4 2002/01/04
1714 Scan for ZOOM API. New object ZOOM_scanset. New functions
1715 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1716 ZOOM_scanset_destroy.
1718 New ZOOM function, ZOOM_connection_last_event, that returns type
1719 of last event (such as "receive data", "send data", "apdu received",
1722 New ZOOM option, schema, that specifies schema for retrieval.
1724 New CCL feature. Qualifiers can be aliases for one or more
1725 other qualifiers (if more than one is given, OR is used).
1727 ZOOM uses named result sets if target supports it.
1729 Two new YAZ client commands: . (dot, which sources a script of YAZ
1730 client commands), and ! (to execute shell command.). Implemented
1733 Working on Debian packages.
1735 --- 1.8.3 2001/11/19
1737 YAZ client enables named result sets only if target supports it.
1739 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1741 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1742 with key="host" to get same result.
1744 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1745 Function Z3950_resultset_record(s) returns references to records
1746 "owned" by resultset. To become owner use Z3950_record_clone.
1748 Function z_ext_record handles Extended Services. Thanks to
1751 --- 1.8.2 2001/11/12
1753 CCL Parser fix: ignore token comma when dealing with and-lists.
1755 Documentation updates for COMSTACK.
1757 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1758 Changed prototype Z3950_records. For some functions, int parameters
1759 were changed to size_t.
1761 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1764 New MARC decode/display function, marc_display_exl, which properly rejects
1765 non-ISO2709 records. YAZ client uses it.
1767 --- 1.8.1 2001/10/29
1769 Fix bug: local attribute set wasn't set correctly in PQF strings.
1773 * Old Z39.50 codecs no longer supported.
1775 Added ZOOM C binding. See http://zoom.z3950.org/
1777 Renamed states for COMSTACKs to avoid confusion with events.
1779 Implemented cs_look and proper cs_rcvconnect.
1781 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1783 Configure detects POSIX threads on OpenBSD.
1785 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1786 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1788 When error is returned from present handler, non-surrogate diagnostic
1789 is returned in present response (and fetch handler is no longer called).
1791 * Minor adjustments to pquery parser (PQF). Token characters may be
1792 escaped by using backslash (C-style).
1794 PQF parser allows string attribute values to be specified. For @attr,
1795 non-numeric characters after the equal-sign are treated as strings
1796 (e.g. @attr 9=title).
1798 CCL trunction character may be defined (@truncation in file)
1800 * function zget_ExtendedServicesRequest sets waitAction to
1801 waitIfPossible (was wait).
1803 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1806 CCL operator names may be set in field definition files (CCL_bibset).
1807 See ccl/bib1 for an example.
1809 Fixes in ASN.1 compiler for C++ compatibility.
1811 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1812 and "op_or" to avoid conflict with C++.
1814 Fixed problem with GNU readline detection on Redhat 7.0.
1816 Added step-size for Scan backend handler.
1818 Fixed bug that made the frontend server crash when no attribute
1819 set was specified for scan.
1821 Front-end server automatically switches to original working directory
1822 when installed as an NT service. Previously -w had to be specified to
1825 Added extended attributes for retrieval module (data1), so that data1
1826 records carry d1_readXML/SGML attributes. d1_read also supports
1827 null-data rules ( <tag/>)
1829 On UNIX when POSIX threads are available, a separate library libyazthread
1830 is created. Programmers should link with that library and the yaz library
1831 when using threads. The reason for the split was that some applications
1832 on Linux, such as Apache, doesn't work well when using shared objects that
1835 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1836 (or any frontend server) in SSL mode by specifying ssl: followed by
1837 address. Only tested on UNIX.
1839 Added feature for CCL module. Virtual structure s=al or s=ol generates
1840 and-list and or-list respectively instead of phrase search.
1844 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1845 log_mask_str. This was done to avoid name conflicts with other libraries
1846 (such as other PHP extensions).
1848 Added raw OID member for preferred record syntax (request_format_raw)
1849 and returned record syntax (output_format_raw) for backend fetch method.
1851 Config file yaz-config now accepts options so that it returns specific
1852 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1854 Shared library support for UNIX using GNU libtool.
1856 * Modified backend interface. Request/Response struct's replaced by
1857 one read/write C struct. For example bend_fetchrequest and
1858 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1859 Every handler - even search has to be registered in bend_init
1860 handler. This means that the YAZ library no longer refers to
1861 external functions and it makes it possible to make the whole
1862 thing a single DLL/SO.
1864 Added Segment handler for backend server.
1866 Added Zmbol/Zebra administrative functions to YAZ client.
1868 Threaded frontend server on UNIX (when POSIX Threads are available).
1869 Starting the server with option -T enables multi-threading.
1873 Added configure option --enable-comp/disable-comp to control use
1874 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1875 located in sub directory asn.
1877 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1878 in ${exec_prefix}/bin along with the other programs yaz-client and
1881 GNU automake used to maintain makefiles.
1883 Added several OID's.
1885 Changed retrieval module so that we can load records with no abstract
1886 syntax defined. Tagpaths in these records are fully composed of string
1889 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1893 On UNIX, the generated makefile now supports a proper 'make install'.
1894 The prefix can be set via GNU configure to set the install location
1895 (default is /usr/local).
1897 * YAZ programs client and ztest were renamed to yaz-client and
1898 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1899 locations, such as /usr/bin,/usr/local/bin,etc.
1901 * YAZ Header files were moved from include to include/yaz. YAZ Header
1902 files are referred to as include <yaz/log.h> rather than <log.h>.
1903 The YAZ include path (-I ..) is therefore the same as before. Programmers
1904 should update their #include statements or use -Ipath/include/yaz
1905 instead. The main motivation for doing this change is that YAZ header files
1906 can be installed in "standard" locations /usr/include,/usr/local/include
1907 without introducing conflicts, since ALL YAZ header files are stored
1908 in subdirectory yaz (under /usr/include for example).
1910 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1911 rather than project/workspace files. We switched because project files
1912 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1915 Changed name of logging function, logf, to yaz_log, to prevent name
1916 clash with some math-log functions. The YAZ header log.h defines logf
1917 to yaz_log (#define) so there should be no incompatibilities by this
1920 Added bend_start/bend_stop handlers for server. These handler are
1921 called on start/stop of server. For windows they are called whenever
1922 a service is started/stopped.
1924 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1925 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1926 in util/yc.tcl. The auto-generated C code structures are, in a few
1927 cases, incompatible with the old decoders. There are differences in the
1928 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1929 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1930 The preprocessor variable ASN_COMPILED is defined when the compiled
1931 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1932 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1933 wish to use the old encoders/decoders you can specify --disable-yc
1936 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1937 version so that it supports both new - and old version of DB Update
1939 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1940 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1941 change. The name parameter can be set to 0 in which no name is specified
1942 for the construction. The macros odr_implicit and odr_explicit sets name
1943 parameter to zero for the construction involved. New macros
1944 odr_implicit_tag and odr_explicit_tag are similar to the others,
1945 except that a name parameter is added. For programmers' that don't use
1946 ODR they probably only need to change the call to z_APDU and z_External.
1948 Added access control facility by interfacing the TCP wrapper library.
1949 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1950 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1951 name of the daemon and enables the access control as specified in
1952 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1954 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1955 den Dool <H.M.vdnDool@kub.nl>.
1957 Added reference ID parameter to most functions in server API - refer
1958 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1960 Changed name of ccl library to libccl.a (was ccl.a).
1962 Fixed bug in decoder for Explain (Category TargetInfo).
1964 Added support for GNU readline in client. Thanks to Jacob Poulsen
1965 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1967 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1968 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1969 IMPLEMENTATION! This change was made to the development version before
1970 the ZIG decided to retract the amendment. If any users MUST be
1971 compatible with the original Update definition, PLEASE CONTACT US, and
1972 we will include a separate definition corresponding to the old Update
1973 ES. Note that because of the change to the ASN.1 of the
1974 TaskPackageRecordStructure we cannot define a single structure that
1975 will support both versions.
1977 * Added const modifier to buffer parameter for some ODR/BER encoding
1978 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1979 completeWAIS, odr_dumpBER.
1981 Fixed bug in client.c which caused a crash when a scanResponse didn't
1982 contain positionOfTerm.
1984 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1985 * will cause an error in a client if a non-YAZ target sends both a
1986 * list of Scan entries and non-surrogate diagnostics.
1988 Retrieval module enhancements. Tag sets may be typed in the reference
1989 to it. From the .abs-file the "tagset" directive takes a third optional
1990 integer type for the tag set referenced. From a .tag-file the "include"
1991 directive takes a third optional type as well. The old "type" directive
1992 in the tag set itself is still recognized but acts as the default type
1995 Backend interface change. Individual Scan terms returned from bend_scan
1996 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1997 in include/backend.h.
1999 Retrieval module enhancements. Multiple tag sets and attribute sets may
2000 be specified in abstract syntax specs. Revised the error/warning for
2001 logging messages reported by the retrieval module when reading the
2004 Object Identifier system (oid_..) changed. The API is backwards
2005 compatible but the oid-routines now allocates new OID's when needed.
2006 Raw OID's may be specified in oid_getvalbyname.
2008 YAZ now uses GNU configure to generate Makefile(s).
2010 * Minor changes in some of the member names of DeleteResultSetRequest and
2011 DeleteResultSetResponse. See include/proto.h.
2013 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2014 and added member 'languages' in TargetInfo (which was missing).
2016 Changed the way attribute sets are handled in the retrieval
2017 module. These are now cached, just like the abstract syntaxes
2020 Changed YAZ so that it links with compiled ASN.1.
2022 Added Explain-schema definitions and mapping routines. The following
2023 Explain categories have been implemented: AttributeDetails,
2024 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2026 Fixed minor bug in Windows version of Server Library.
2028 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2030 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2032 Added EXTERNAL: UNIverse Resource Report (non-standard).
2034 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2035 ENUMERATED and SET OF.
2037 * Added 'const' to some of the char pointer arguments for the
2038 functions, data1_read_node, data1_getelementbytagname,
2039 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2042 Fixed bug in data1_insert_taggeddata - the last_child member of
2043 parent wasn't initialised.
2045 * Changed data1_read_record and data1_read_node so that the supplied
2046 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2047 doesn't refer to any parts of the "SGML"-buffer.
2049 Fixed bug in server library (Windows version of statserv_remove).
2051 * Changed code so that it compiles as C++. The type definition
2052 of Odr_fun which is a member of Odr_arm was changed. The result is,
2053 that an explicit typecast is needed for the fun pointer when
2054 using Odr_arm - as in:
2055 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2057 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2059 Implemented the new structured date and time definition as approved
2060 by the ZIG. Added schemaId element to the specificTag in Espec-1
2061 (also approved at the last ZIG). Thanks to RVDM.
2063 Added some Object identifiers (RVDM).
2065 Changed the Update Extended Service (RVDM).
2067 Added command "refid" to client which specifies referenceId for
2068 the following requests.
2070 Implemented extended service handling for server. See ztest.c
2071 for an example as well as backend.h. New handlers are registerd
2072 in the Init handler.
2074 * Changed interface for sort in server.
2076 Added new members to statserv_options_block. It allows a server
2077 to read options from another source than just the command line. Thanks
2078 to Charles Woodfield.
2080 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2081 renamed to zboolean. Some C++ compilers complained about the name.
2083 Minor changes to gils.abs. Added index 's' (sort) on title
2084 and date/time-last-modified.
2086 --- 1.4pl2 1998/1/30
2088 Fixed bug in server library regarding inetd mode (-i). This bug
2089 was introduced by release 1.4.
2091 --- 1.4pl1 1998/1/29
2093 Added sort facility in client and backend server interface.
2095 Fixed problem with dependencies in Makefile(s).
2097 Fixed bugs for encoders/decoders of extended services and
2100 Implemented sub-tree feature for schemas. Sub-trees are
2101 referenced in *.abs-files. See explain.abs for an example
2102 of the use of this feature.
2104 Modified bib1.att; local attributes for ANY didn't include
2105 ANY itself (only affects use of the retrieval module).
2107 Fixed bug in plain SGML reader in function data1_read_node:
2108 tags with prefix "var" was incorrectly interpreted as variants.
2110 Added feature "sub-schemas" to enable references to - and definitions
2111 of - group of elements.
2113 * Removed member parent from type data1_element (in data1.h).
2115 Implemented function odr_nullval() that returns the value of
2118 * Removed member num_children from data1_node (in data1.h).
2120 Made NT service interface part of the server library. The
2121 function statserv_main uses the NT service when required and
2122 calls the statserv_start / statserv_close routines.
2124 Routine zget_SearchRequest and zget_PresentRequest fills
2125 resultSetName/Id member with "default" instead of "Default".
2127 Fixed memory leak in server. Request queue member wasn't freed.
2129 Fixed nmem_exit so that memory is freed.
2133 Revised the CCL parser utility to be thread safe.
2135 Added function, oid_ent_to_oid, to replace the function
2136 oid_getoidbyent, which is not thread safe.
2138 * Added nmem_init and nmem_exit to initialize and release
2139 NMEM resources. Function nmem_init should be called once in the
2140 initial thread before NMEM/ODR is used. statserv.c and client.c
2141 have been changed accordingly. The change was necessary to make
2142 NMEM thread safe. The NMEM memory pool is shared amongst threads
2143 in a process. Unix-based applications will still work fine without
2146 Added NT Services interface for the the Z39.50 (statserv) Server.
2147 Refer to the ztest.c source on the usage.
2149 Windows 95/NT port using MSVC5.0. Project files are included in the
2152 * Defined new 'global' handle for the retrieval (data1) system. The
2153 new handled, data1_handle, describes the state of the data1 system.
2154 This handle is passed as first argument to virtually all
2155 data1 related routines. The functions data1_create and data1_destroy
2156 creates and destroys a data1 handle respectively.
2158 Added ODR encode stream member to all backend request structures
2159 init, search, scan etc. This stream should be used to allocate all
2160 memory used for the response when thread safe operation is needed.
2162 Changed the comstack utility, cs_addstr, to be thread safe. The
2163 returned hostname string returned by the function is now part the
2166 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2167 function. The cs_straddr takes a COMSTACK handle as argument, so this
2168 function must be used after cs_create and before bind/connect.
2169 This function is thread safe.
2171 Moved test server to 'ztest' directory - generic server code still
2172 in 'server' directory.
2174 Made prefix query (pquery.c) utility thread safe.
2176 Added new function modifier YAZ_EXPORT to 'export' public DLL
2177 functions when using windows (see include/yconfig.h).
2179 Added definitions to the OID database (util/oid.c) (RVDM).
2181 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2183 Added call to ccl_rpn_delete in client program.
2185 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2186 release of RPN structure.
2188 Added support for C++, headers uses extern "C" for public definitions.
2189 With input from RVDM.
2191 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2192 Thanks to Ronald van der Meer (RVDM).
2194 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2196 Added support for private extensions to the OID database
2197 (oid_setprivateoids()). Thanks to RVDM.
2199 Added optional, physical ANY (key replication)
2201 Fixed null-reference problem in GRS-1 output filter.
2203 Proximity operator added to Prefix Query Format (PQF).
2205 In test client command "base" accepts multiple databases.
2207 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2211 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2213 Smallish bug-fixes in the new encoders/decoders (explain).
2215 Bug fixed in DeleteRequest.
2217 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2219 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2221 Added SOIF syntax (using private OID for now) to retrieval module and client.
2223 Added Update extended service.
2225 Added SearchResult-1 additional info structure.
2227 Added optional CCL (ISO8777) interpreter as separate module. Available
2230 --- 1.2 1996/6/10 (1st anniversary release)
2232 Added Summary record syntax. Lightly tested.
2234 Added OPAC record syntax. Untested.
2236 Added ResourceReport service encoders/decoders. Untested.
2238 Fixed bug in z_Unit - wrong tagging on unitSystem.
2240 Fixed bug in the DiagRecs decoder.
2242 Added options for max PDU size and session timeout to frontend-server.
2244 Added documentation of query-language parsers and other supporting utilities.
2246 [frontend-server] Added Attribute set to the bend_scanrequest API.
2248 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2249 surrogate diagnostics were generated.
2251 [retrieval] Allow multiple local values for attribute.
2253 [retrieval] Allow multiple attributes per element in .abs files. index type.
2255 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2257 --- 1.1pl2 1996/4/10
2259 Minor changes, mostly specific to Zebra's requirements (retrieval)
2263 Repaired bug in frontend server when running multiple listening
2264 endpoints in dynamic mode.
2266 z_External() now won't break if a known, ASN.1 value comes encapsulated
2267 in an octet-string. The value will pass through unmodified in an Odr_oct.
2269 Added a bit of code to the demo client to decode & display
2270 ASN.1-structured records represented in the octet-aligned branch of
2271 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2273 Added z_ext_getentbyref() to the ASN module. Doc updated.
2275 * Completed the SCAN definition in the ASN module. This may break SCAN
2276 code based on older YAZ-versions at compile-time. The fix is easy -
2279 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2280 under the SCAN definition. Remember to initialize this, server-people.
2282 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2283 that this does not extend to ODR and ASN.
2285 Comstack allows insertion of established socket (primarily for
2286 inetd-operation of servers). Doc updated.
2288 Front-end server can now start from the inetd in TCP mode. Doc
2291 --- 1.0pl4 1996/1/24
2295 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2296 the rank and record number.
2298 Adjustments to the frontend server.
2300 Fixed diagnostic BER dumper. It ignored the file argument.
2304 Various changes to retrieval module.
2306 Changed the union discriminators of the protocol files from enums to
2307 ints paired with #defines.
2309 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2312 *Changed operator in the RPN structure to 'roperator', again to avoid a
2315 Fixed problems in Explain decoders/encoders.
2317 --- 1.0pl2 1995/12/6
2319 Memory bug in log module fixed.
2321 --- 1.0pl1 1995/12/5
2323 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2325 Bug in Explain DatabaseInfo module fixed.
2327 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2331 The shift to v1.0 signals that we now consider the *core* functionality
2332 of YAZ reasonably stable (the core being more or less equivalent to
2333 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2334 tested (Explain not at all - though that will happen soonish).
2336 Minor changes to code to support Windows port.
2338 Various minor changes after we're getting to use GRS-1 & co. more.
2340 Added Espec-1 format.
2342 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2343 of the protocol and it cannot be selected when encoding (maps into 'string'
2344 when decoding). Needed to talk to some servers.
2346 Demo client can request simple element set names.
2348 Added Diagnostic Format encoders/decoders.
2350 Added simple Close handling to frontend server (no hooks for resource
2351 reporting yet), and demonstration client.
2353 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2355 --- 1.0b3 1995/08/24
2357 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2358 handled incorrectly when records were requested in the searchResponse. This
2359 will only affect you if you use the frontend-server.
2361 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2362 Test-client will ask for and print GRS1. Ztest will return dummy records
2365 Added Explain encoders/decoders to the service-level API. Untested.
2367 Added Extended Services: Item Order encoders and decoders to the Service-
2368 level API. Untested. We could use a recent copy of the pertinent bits
2369 of the ILL protocol to add those bits.
2371 Added diagnostic format 1 encoders/decoders to the service-level API.
2374 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2375 odr_cons.c, which causes a more correct output.
2377 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2378 was always set to 0 when no records were requested in the searchRequest.
2380 * Added better external-handling. This shouldn't harm old code that
2381 *encodes* externals. It can break code that looks for a
2382 'single-ASN1-type' representation, since those types that are known
2383 are now decoded immediately. Look at the SUTRS sample code in
2384 seshigh.c and client.c. Documentation updated.
2386 Handling of structured records in bend_fetchresponse. Length -1 marks
2387 structured record, type is deduced from format field.
2389 --- 1.0b2 1995/06/27
2390 Fairly quick maintenance release to add SUTRS support.
2392 Fixed handling of SUTRS records in the demonstration client.
2394 * Added format field to the bend_fetchrequest and bend_fetchresponce
2395 structures of the backend API (frontend server). When the record is
2396 returned, the value of the format field is mapped to an OID. The
2397 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2398 of the record. The special value VAL_NONE in the bend_request means
2399 that no specific format was requested by the client. Documentation
2400 updated accordingly. Test server (ztest) will return a fixed dummy
2401 SUTRS record if your client requests SUTRS.
2403 Documentation updated accordingly.
2405 You can now set external libraries and RANLIB support in the top-level
2409 First public release.
