1 Added yaz_poll which is a wrapper for select/poll. When poll is available
2 and non-buggy, it is used, by yaz_poll . This allows more than 1024
5 Added ICU chain component - which used to be part of Pazpar2.
7 Added HTTP tunnel facility for COMSTACK, bug #1752.
8 This is a facility that allows a Web proxy, such as squid, to tunnel
9 Z39.50 traffic. This facility is "transparent" to must applications
10 using YAZ. It's enabled by using pseudo transport connect: followed by
11 the proxy address, followed by command, then follwed by he regular
12 "virtual" addresss. For example,
13 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
17 Fixed bad memory reference in ZOOM_record - cuased by member not being
18 initialized. This was a problem only in YAZ 3.0.12.
20 Fixed bug in conversion from MARC to XML: Non-XML characters in control
21 fields were not removed.
23 Changed the way C code is generated from codetables.xml. Made a MARC-8
24 conversion trie for each characterSet section rather than codeTable.
25 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
26 of codetables.xml from Larry Dixson, LOC. Bug #1464.
30 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
31 from ZOOM_record_error).
33 ZOOM C function ZOOM_record_get returns record schema for type="schema".
35 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
37 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
39 Better SRW-to-Bib-1 diagnostic mapping.
41 ZOOM C and yaz-client announces SRU version 1.2 by default.
43 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
46 Fixed in yaz_sru_decode to allow other version than 1.1.
50 Added support for SRU scan for ZOOM.
52 Added support for the use of the older versions or Extended Service
53 Update in ZOOM. To faciliate this, an option "updateVersion" may be
54 set to the version , 1=first, 2=second, 3=third. The third version is
55 what ZOOM C has used so far. And that, obviously, is the default.
57 Added support for CCL queries in Z39.50 queries sent to the GFS (and
58 therefore in Zebra and in SimpleServer-based applications). The new
59 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
60 qualifier file used to transform incoming CCL queries into Type-1 RPN,
61 which is passed into the back-end search callback function.
63 Added support for HTTP Basic authentication in clients: the SRU/W
64 codec encodes the username/password elements of the PDU structure
65 appropriately, and these may be set using the "user" and "password"
66 options in ZOOM-C applications (the same options that are used for
67 Z39.50 authentication).
71 Fixed bug #1208: SSL appears to be broken in ZOOM.
73 Fixed bug #1206: Libxml2 include path weirdness.
75 Added oid_name_to_dotstring.
77 Allow elementSetName to be specified for ZOOM C record update.
79 Allow waitAction to be specified for ZOOM C based for Extended Services.
81 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
82 syntax OID. Bug introduced in YAZ 3 series.
84 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
88 Fixed bug #1157: yaz-client does not read .yazclientrc from current
89 directory. yaz-client now reads commands from file given by option -f
90 if specified; then tries to read .yazclientrc in current directory.
91 Failing that, it reads .yazclientrc from user's home directory.
93 Added support for correlationInfo Note and ID for Record Update via
96 Added yaz-client command querycharset which specifies character set for
97 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
98 (termListAndStartPoint).
100 Charset ISO5428:1984 is an alias for ISO5428-1984.
102 Implemented a way to perform scan in a result set using Z39.50. This
103 is achieved by attaching the result set name in the characterInfo
104 (type InternationalString) of OtherInformation in the Scan Request PDU.
105 The result set is identified in the otherinformation by the new OID:
106 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
107 This allows for scan in result set and faceted search . Zebra did some
108 of this in the APT term using attribute type 8 and value being result
109 set. Using the OtherInformation approach for this is cleaner and easier
110 to work with in proxies and the like. This facility can be used in
111 yaz-client using new command setscan which takes a result set as first
112 argument, start position (APT) as second.
114 Changed decoding of SRU XML packed records to deal with servers that
115 have recordData with XML data with multiple root nodes. Also make
116 comparison for recordPacking case insensitive. Again, one server
117 returns "XML" where others return "xml".
119 For SRU responses allow Content-Type application/xml as well as text/xml.
123 Fixed bug in character set conversion of BER strings. Bug introduced
128 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
130 For OID class, use oid_class consistently.
132 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
135 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
136 character set for bibliographic information interchange". By Giannis Kosmas.
138 Added documentation on new OID API.
142 Changes to generic frontend server interface: added new member
143 'query_charset' for bend_initrequest structure. A backend init handler
144 should set this member to its native character set for query terms.
145 When defined, the frontend server logic will announce this character set
146 to a client if the negotiationModel bit is set by the client. All server
147 implementors are encouraged to specify this. If a backend server does not
148 specify this a warning is issued using yaz_log(YLOG_WARN,..).
150 Added CCL utility to remove terms (stop words) from resulting RPN
151 tree. This is handled by functions with prefix ccl_stop_words_ .
153 New ZOOM C option, "rpnCharset", which allows client-side conversion of
154 terms in RPN queries.
156 Clean-up the CCL API. Moved some internal structures from ccl.h to
157 private header cclp.h. Changed ccl_parser_create so that a Bibset must
158 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
159 This is replaced by ccl_parser_find_str which takes a string instead.
161 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
162 libyaz.la is the core of YAZ except the generic frontend server and
163 does not depend on POSIX threads anymore. libyaz_server.la is the
164 generic frontend server facilities and uses POSIX thread functionality
165 if available. The libyaz.la no longer depends on POSIX threads because
166 the number of global structures is limited. NMEM no longer re-uses blocks
167 between threads ; it simply free's memory immediately but allocates in
168 "large" chunks as usual. We don't expect any performance penalties
169 because of this. The yaz_log system is still using a global log_level so
170 caution must be taken when modifying it with yaz_log_init_.. +
171 yaz_log_mask_str. This, however, should not cause any trouble because
172 these functions are called during initialization of application code
173 anyway. `yaz-config --libs server` returns libs for server applications;
174 `yaz-config --libs` returns libs for non-server applications.
176 New OID database - with public definitions in oid_db.h. Removed old OID
177 database including the head oid.h and definitions such as enum oid_value
178 and struct oident. The new OID database uses the same string names as
179 before but the 'protocol' is gone. There are now only two representations
180 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
181 converts from string to OID; functions with prefix yaz_oid_to_string
182 converts the other way.
184 Change to emit_term() in CQL-to-PQF query translation: when a term has
185 the /regexp relation modifier, do not process it for leading and
186 trailing "^" and "*", which have quite different meanings in regular
189 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
190 write handlers no longer carries a 'last' parameter. This will make
191 yaz_iconv flush "less" characters. A flush is performed by call to
192 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
194 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
195 removed, because function yaz_query_to_wrbuf does the same.
197 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
198 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
200 Deprecated MARC utility functions removed.
202 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
205 Branch split: YAZ_2_1_55_branch
207 --- 2.1.54 2007/03/16
209 Fix to ZOOM-C so that transparent reconnection is properly handled on
210 connections that are in asynchronous mode.
212 Fixed compilation on OpenBSD 4.0.
214 Large strings in GRS-1 records are now properly displayed in yaz-client.
216 Added character conversion support for "advancegreek"; based on patch from
219 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
220 sequence is met. Before the error was not set so it would be unknown.
222 Adjust yaz-marcdump MARC reader so that it skips until record separator
225 --- 2.1.52 2007/03/07
227 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
228 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
229 fd_set structure used as a bitmask for the FDs to be selected on.
231 Using ACX_PTHREAD macro to check for POSIX threads.
233 Fixed have-vsnprintf check.
235 --- 2.1.50 2007/02/23
237 Fixes for configure on BSD. Bug #900.
239 Added snprintf/vsnprintf wrappers for systems that don't have
240 limits (heavens forbid).
242 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
243 created before all previous tasks were completed and removed from the
244 task queue, the new task could be removed by a mistake.
246 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
248 Implemented pass-through CQL-to-PQF conversions. Bug #861.
250 Fixed bug #832: Problem with MARC/charset in yaz-client.
252 Fixed bug #668: save command line history for yaz-client.
254 Fixed bug #830: pkg-config support.
256 --- 2.1.48 2007/01/23
258 Extended ZOOM result set options with two options that may be read by
259 a client: resultSetStatus and presentStatus with values as specified for
261 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
263 Fixed bug #827: Using SSL fails on Debian etch.
265 Fixed bug #826: Weird looking chars for set of MARC records.
267 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
268 that is treated as an ItemOrder with itemRequest being an XML document
269 external. The value of "doc" is the content.
271 Extended the GFS search facility. New member of bend_search_rr
272 'estimated_hit_count' signals that hits is known to be an estmate
273 (higher or lower than real hit count). New member 'partial_resultset'
274 signals that the search was partial (hit count is lower or equal than
275 real hit count). For Z39.50, the information is stored in resultSetStatus
276 member of SearchResponse APDU. For SRU, the information is signalled
277 via SRU diagnostic 59: "Result set created with valid partial results
280 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
282 --- 2.1.46 2007/01/13
284 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
286 Added ZOOM_connection_peek_event.
288 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
289 the following new functions:
290 ZOOM_event_nonblock, ZOOM_connection_process,
291 ZOOM_connection_get_{socket,mask,timeout},
292 ZOOM_connection_fire_event_{timeout,socket}.
293 The existing blocking event handler, ZOOM_event, is a wrapper for the
294 + blocking ZOOM_event_sys_{poll,select}.
296 Implemented function ccl_xml_config which parses XML version of CCL
297 configuration (bug #798).
299 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
301 Added timings utility (yaz/timing.h)
303 --- 2.1.44 2007/01/03
305 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
308 Fixed bug #779: Rotation of apdu.log fails.
310 Fixed for character set conversions:
311 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
312 Honor G1 set in MARC-8 decoding.
314 --- 2.1.42 2006/12/17
316 Fixed bug #775: char conversion does not handle Alternative UTF-8
319 Implemented function yaz_marc_read_line which parses MARC line format
320 records. There is a wealth of formats out there. So far, this function
321 reads line records produced by yaz_marc_write_line.
323 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
324 more generic and easier to remember(!) options: -i format and -o format
325 which specifies input format and output format respectively - where
326 format is one of "marc", "marcxml", "line", "marcxchange".
328 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
329 does not print anything except warnings for records.
331 For yaz-marcdump, added support for MARC split into files (-s) with a given
334 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
335 spec, at http://www.loc.gov/standards/sru/record-update/
336 This has changed the binary layout of the following structs:
337 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
338 bend_update_rr . Patch by Ko van der Sloot.
340 Added GFS utility function bend_assoc_is_alive which returns 1 if
341 association is still alive (client is connected); 0 otherwise (client
342 closed connection). This allows busy servers to stop working for
345 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
346 been a separate piece of software. This version of ziffy has been modified
347 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
349 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
351 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
352 Client code may now interrogate options such as "init_opt_sort" to
353 find out whether the server claims to support various options.
355 --- 2.1.40 2006/11/27
357 Added utilities yaz_{set,get}_esn to set/get element set name from
360 Removed the build of libyazthread.la. The libyaz.so is the threaded version
361 of YAZ and has been so since YAZ 2.1.10.
363 Implemented ZOOM_record_error which returns error information for
364 record (surrogate diagnostic).
366 --- 2.1.38 2006/10/31
368 Updates for SRU Update by Ko van der Sloot:
369 1. Changed name from "operation" to "action"
370 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
371 versions in the code, marked as 'backward compatible'.
372 3. Added diagnostics for SRU Update.
374 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
376 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
378 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
380 For GFS, fixed problem with SRU diagnostic 'First record position out of
381 range' being issued for 0 hits.
383 zoomtst10 part of Windows Build.
385 --- 2.1.36 2006/10/13
387 Implemented yaz_filepath_comp which splits a path into file path
388 components (required by Zebra 2.0.3+).
390 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
391 BSD inspired license until now so this should not have any real impact on
392 anybody. See http://www.opensource.org/licenses/bsd-license.php
394 Fixed bug #687: Missing log lines.
396 Fixed bug #678: CQL to PQF translation does not preserve double-quote
399 Fixed bug #689: SRU diagnostics to be added.
401 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
402 whether a connection is idle (no more work do do).
404 --- 2.1.34 2006/10/04
406 Change type of optval from long to int for invocation of setsockopt with
407 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
409 Added support for specifying the max log file size for the Generic
410 Frontend Server. The size is given with option -r.
412 --- 2.1.32 2006/09/21
414 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
416 --- 2.1.30 2006/09/17
418 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
421 Fixed bug in Generic Frontend Server that could cause a server to stop
422 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
424 For the generic frontend server, the maximum record size is used as maximum
425 size of incoming packages (SRU + Z39.50). The value until was previously
426 only used in Z39.50 Init negotiation and, later, in a session controlled
427 sizes of records returned. This is controlled using -k option. It can be
428 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
430 --- 2.1.28 2006/09/04
432 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
435 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
437 New option for yaz-marcdump -lpos=value which allows setting a portion
438 of MARC header to a certain value.
440 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
442 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
443 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
445 --- 2.1.26 2006/08/15
447 Fixed problem with SRU mode type (soap, get, post) for yaz-client
450 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
452 --- 2.1.24 2006/08/08
454 Fixed MARC ISO2709 encoding routines to deal with character set
457 Minor changes to GFS logging. Database included in search request log
460 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
461 cached/multiple records.
463 Shared libraries are built by default on Unix+configure.
465 Changed cql2pqf transformation to use a different evaluation order. The
466 new order is: always, relation, structure, position, truncation, index
467 and relationModifier. Old order was: always, relation, relationModifier,
468 structure, index, position, truncation. Note that the the latter ones
469 override former ones for identical attributes.. The new scheme means that
470 it is possible to override any existing attribute with a relationModifier.
471 And also that it is possible to override everything for the index rule
472 (except the ones listed in relationModifier). No order is perfect but this
473 one, we believe, covers more real cases.. The "always" should have been
474 called "default", since the attributes there can be overridden with all
477 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
478 compilation phase, but also for yaz-config --cflags output. This allows
479 us to have public headers with Libxml2 stuff in them . It should also,
480 eventually, make Libxml2 checks redundant in packages using YAZ, such
483 --- 2.1.22 2006/06/15
485 Changed SRU update structure bend_update_rr so that SRU diagnostics are
486 stored in uri, message and details.. Previously diagnostics were stored
487 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
488 compatibility.. but he's probably the only one affected, so.
490 Added support for CCL, compiled on the client side, in ZOOM-C. This
491 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
492 input; the resulting query objects can be used for for searching with
493 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
495 YAZ' configure searches for OpenSSL by default.
497 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
498 SL_CTX_use_certificate_file. See
499 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
500 for more info. Thanks to Ko van der Sloot.
502 --- 2.1.20 2006/06/02
504 Bug #600: SRU GET, POST support for yaz-client. Introduced
505 command 'sru' which selects method SOAP/GET/POST.
507 Allow missingValueAction to be specified for the sortspec string -
508 function yaz_sort_spec. By default, the missing value action is null.
509 Use ! to specify "abort". Use = followed by stringvalue to specify default
512 Ensured that Present-handler (if defined) is called in GFS before any call to
513 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
514 searchRetrieve requests.
516 Documentation for YAZ is now based on the Docbook XML/XSLT using
517 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
518 is no longer depending on jade/openjade or docbook-to-man scripts.
519 PDF is no longer part of the distribution - but can optionally be
520 made using DSSSL/jadetex or FOP.
522 Added retrieval handling support in Generic Frontend Server to support
523 conversion between MARC/XML as well as XSLTtransforms. See
524 etc/yazgfs.xml for an example.
526 Added Authentication support to Generic Frontend Server in SRU
527 mode. Authentication using HTTP Basic is supported, as is the use
528 of 'x-username' and 'x-password' parameters in the request itself.
530 Added support for a new character set MARC8s identical to MARC8 except
531 that it converts combined characters to single Unicode characters in the
532 Latin-1 range (when possible).
534 --- 2.1.18 2006/04/24
536 ASN.1 compiler 0.4: generates brief Doxygen file header for
537 generated .h/.c files.
539 Utility yaz_iconv now supports conversion to MARC-8.
541 New facilities for the MARC module. The reading - and writing of
542 content are separate methods for the yaz_marc_t handle. The following
543 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
544 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
545 format). Write functions have prefix yaz_marc_write_.. The existing
546 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
547 available. Removed support for OAI-MARC and simplexml (not the
548 simplexml from PHP5).
550 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
551 to be returned for this connection.
553 --- 2.1.16 2006/03/31
555 Allow multiple languages and charsets to be specified with
556 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
557 negcharset iso-8859-1,utf-8
559 Translation of proximity nodes from CQL into PQF now works.
561 Moved to automake 1.8, 1.9.
563 Added function yaz_log_set_handler which allows a log handler to be
564 installed. This handler will be called for all log messages. Output
565 to file is also produced; but that can be disabled by passing NULL
566 fname to yaz_log_init_file.
568 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
570 For SRW (including GFS), accept application/soap+xml as content-type
573 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
574 produces NO stylesheet reference even if a default stylesheet is specified
577 --- 2.1.14 2006/03/14
579 Updated Windows package to include yazd.dll + yazd.lib for the
580 Development component.
582 If the environment variable YAZ_LOG is set, then it is used as a
583 string indicating the default level of logging to use if not
584 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
585 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
586 used as before. So, for example, to omit warnings from YAZ logging,
589 cql_transform() now map structure and other attributes before indexes,
590 so that index-specific structures and other attributes can override
591 defaults. So now a combination of mapping specifications such as:
593 index.dc.date = 1=date-modified 4=5
594 does the right thing.
596 cql_transform() now also respects the "always" mapping specification,
597 which establishes an initial set of attributes to be used for all
598 terms except where overridden by more specific attributes associated
599 with the index, relation or modifier.
601 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
602 which mode to use; one of "post", "get" or "soap" (SRW, default).
604 Fixes for yaz_iconv routines: changed trie-based character set conversions
605 to use only non-negative values for bit fields due to Sun's C compiler not
606 supporting negative values.
608 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
609 sequences where not read correctly. Fix by Rustam Usmanov.
611 Updated win/makefile to use options, settings which makes things
612 compile with VS C 2005.
614 --- 2.1.12 2006/02/01
616 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
618 In ZOOM socket code, use select instead of poll on MacOSX.
620 ZOOM-C now support client-side compilation of CQL into RPN that is
621 sent to the server, enabling CQL to be used against all Z39.50
622 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
623 ZOOM_query object, and submit it using ZOOM_connection_search().
624 The CQL-to-RPN translation uses a configuration file, the name of
625 which must be specified in the Connection's "cqlfile" option.
627 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
628 function, which takes as its start-term parameter a ZOOM_query object
629 (which may have had either CQL or RPN set into it).
632 --- 2.1.10 2005/11/29
634 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
635 GFS to support this as well. Backend handler, bend_srw_update, does the
636 update work. Code contributed by Ko van der Sloot.
638 Allow retrieval of Search Result-1 information in ZOOM by the use of
639 options that are attached to a result set. ZOOM documentation updated
642 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
643 UTF-8 conversion. Patch by Raj Patel.
645 Added option -m to GFS to control formatting of timestamps in log file.
647 Added 'exit' as synonym for 'quit' in yaz-client
649 Added support for specifying SRW resultSetId + resultSetIdleTime in a
650 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
651 for the new members. Patch by Ko van der Sloot.
653 Added support for SRU POST. It is supported for content-type
654 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
656 Do not build the separate Multi-threaded (MT) library libyazthread.la.
657 Instead make the library libyaz.la multi-threaded. Threading as a whole
658 can still be disabled by configure option --disable-threads. Previosly,
659 with older GLIBCs there were problems with MT libs under Apache. This
660 has now been fixed a long time ago.
662 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
665 CQL module modified to be case insensitive for relations/indexes/operations.
667 Fixed bug in CQL transform code: incorrect value relationModifieder
670 Added 'show all' command for yaz-client which retrieves all results
673 Added new yaz-client, xmles, which takes a (private) OID and
674 a document to be sent as an extended service request.
676 Describe new yaz-client commands wait_response and set_auto_wait.
678 Increase TCP/IP listener backlog from 3 (which I am guessing was
679 copied from the SunOS manual entry way back when) so SOMAXCONN, so
680 that the socket will queue as many incoming connections as it's able
681 to handle ongoing connections. In other words, it will never now
682 refuse a connection that it would be able to handle merely because
683 it's not got around to accepting() enough of the pending connections
684 yet. This is the behaviour anyway under Linux, where the listen()
685 argument is ignored; but not under BSD and on systems such as
686 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
687 YAZ-based servers should now be uniform across operating systems in
690 yaz-marcdump uses 64-bit file access on some systems. This is enabled
691 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
692 This allows yaz-marcdump to read large MARC batches (>2 GB).
694 Modified all YAZ source files - except the source which is auto-generated
695 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
698 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
699 corresponding to the existing *_setl() function. These allow option
700 values containing arbitrary valuues.
702 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
703 ZOOM_resultset_sort() in new applications. Its behaviour is identical
704 except that it returns an indicator of whether or not the sort
705 criterion was accepted (0 for OK, -1 for invalid).
709 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
710 MARC output rather than returning "new" buffer.
712 yaz-client warns about unknown init options.
714 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
718 Added support for SRW sort in Generic Frontend Server. Patch
719 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
720 sortKeys - or NULL if none is provided.
722 Fixed bug #307: It was impossible to specify indefinite/no timeout
723 for ZOOM_event. Special timeout value -1 now means indefinite timeout
726 Added support for multiple languages and charsets to be specified in
727 ZOOM. Each charset/language is separated by a blank. If negotiation is
728 in effect in init-response, Option
729 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
730 Code based on patch by Vasiliy Osadchuk.
732 Fixed bug #306: infinite recursion that occurred when calling
733 yaz_log_level_init as the first call (before other log level or
736 Fixed bug in scan handling in front end server: if preferred-Position-In-
737 Response was non-present, a NULL pointer referece was performed.
741 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
742 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
743 now defined for all those error codes. So instead of putting 109 in
744 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
745 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
747 Modified the yaz-marcdump utility to skip garbage bytes between MARC
750 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
752 Program yaz-client now exits and produces an error message if multiple
753 Z39.50 servers are specified on the command line (none or one allowed
756 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
761 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
763 Fixed bug #272: Preserve spacing for CCL terms.
767 Added support for virtual hosts and multiple backend servers for
768 the YAZ frontend server. The configution is XML based and
769 support specificition of CQL to RPN mappings and explain information.
770 See section "Virtual Hosts" in the YAZ manual.
772 Extended OPAC display utility. OPAC display utility renders
773 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
774 to supplement yaz_marc_decode_wrbuf.
776 Fixed a bug in MARC decoder that could caused it to crash for some
777 invalid MARC records. More diagnostics and warnings where added in
778 XML output (warnings, etc are stored in comments).
780 --- 2.0.34 2005/02/08
782 Fixes for UNIX domain sockets. Bug #261.
784 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
786 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
787 Added yaz_marc_subfield_str which defines subfield lead string which is
788 used in YAZ_MARC_LINE format. Default string is blank+$. Added
789 yaz_marc_endline_str which defines end of fields string used in
790 YAZ_MARC_LINE format. Default string is newline.
792 Experimental support for MarcXChange. This format can be produced
793 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
794 http://www.bs.dk/standards/MarcXchange.xsd
796 Added yaz-client commands scansize that sets maximum number of
797 entries to be returned by scan.
799 --- 2.0.32 2005/01/11
801 Added support for SRW scan in yaz-client and Generic Frontend Server.
803 * Added whereInList member to SRW Scan Term.
805 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
807 Fixed NMEM system to return aligned blocks on the smallest boundaries
808 that are suitably aligned for all possible types on the particular
809 architecture YAZ is being built for.
811 --- 2.0.30 2005/01/04
813 Fixed numerious warnings that was issued with newer versions of GCC.
815 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
816 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
819 Make YAZ Generic Frontend Server slightly faster.
821 Enhance (and reduce) logging for Generic Frontend Server.
823 Revert YAZ log system so that it flushes every write operation
824 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
826 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
827 instead of LOG_, due to name clash with syslog(3). LOG_ are still
828 present. New applications should define YAZ_USE_NEW_LOG=1 - this
829 will effectively disable old definitions.
831 --- 2.0.28 2004/11/09
833 Added yaz_log_time_format which specifies log format using
836 Added yaz_log_module_level which returns mask for a module. Value
837 is non-zero mask a if module is enabled; zero if disabled.
839 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
840 in include/yaz/cql.h.
842 Fixed bug #176: Dont throw diagnostics on empty SRU args.
844 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
846 Fixed bug #172: RPM builds does not enable SSL.
848 Doxyfile.in part of dist. Doxyfile generated by configure.
850 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
851 are given and the corresponding component does not exist.
853 Extend CCL documentation in YAZ reference. Describe r=r.
855 --- 2.0.26 2004/10/01
857 Fixed MARC->MARCXML conversion to properly deal with
858 fields, subfields, indicators having non-ASCII characters.
860 Fixed MARC->MARCXML conversion so that ASCII control characters
861 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
864 Added YAZ GFS support for conversion from Z39.50 surrogate
865 diagnostics to SRW surrogate diagnostics.
867 Bug fix: YAZ GFS did not return schema in explainResponse.
869 --- 2.0.25 2004/09/30
871 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
872 now converts recordSchema to elementSetName as well as schema URI.
874 Fixed bug in COMSTACK that prevented HTTP request packages from being
877 --- 2.0.24 2004/09/29
879 Added CCL facility r=r "range" which is similar to r=o "ordered" but
880 does not require white-space before and after the dash in a range, e.g.
881 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
884 Fixed a few AC_TRY_LINK configure tests that did not operate properly
885 due to new GCC removing "redundant" code.
887 Added yaz-client commands scanpos and scanstep that sets preferred
888 position and step-size for scan.
890 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
892 Added CCL utility ccl_qual_buf which parses one or more CCL
893 spec lines in a buffer.
895 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
896 of name and value - ignoring empty lines and comments.
898 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
900 Added odr_get_element_path which returns current element path for an
901 ODR handle. This utility is useful in error handling or user-defined
904 Added ODR_PRINT utility odr_set_stream which is is a more generic
905 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
906 to a write function and pointer to close function. The close function - if
907 non-NULL - will be called during odr_destroy.
909 Fixed bug in CCL parser where truncation char was not removed from
910 right side when truncation=both was in effect.
912 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
915 --- 2.0.23 2004/08/11
917 Fix buffer overrun in CQL parser when dealing with proximity (%).
919 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
920 to UTF-8/UCS conversion is now only based on codetables.xml.
922 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
924 --- 2.0.22 2004/08/06
926 Add support for more "commit changes" in ZOOM (uses Extended Services).
928 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
931 Yet another small fix for configure of SSL.
933 --- 2.0.21 2004/05/14
935 Fix SSL libs for configure when --with-openssl=DIR is given.
937 --- 2.0.20 2004/05/10
939 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
941 SSL comstack now uses yaz.pem certificate file on server side
942 by default. Certificate filename can be configured by calling
943 comstack function cs_set_ssl_certificate_file before cs_bind is used.
945 Fix bug regarding multiple calls to ZOOM_connection_connect.
947 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
949 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
950 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
952 ZOOM now allows inspection of X509 peer certificate for verification.
953 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
955 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
956 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
957 as "modular" but it simplifies things.
959 Added cs_get_peer_certificate to that returns peer X509 PEM.
961 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
962 NULL if SSL is unavailable.
964 Documentation about MARC decoding tools.
966 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
968 --- 2.0.19 2004/03/30
970 Rename CHANGELOG to NEWS to follow GNU style packing.
972 Fix bug with missing initialization of member in init_diagnostics.
973 This bug affects threaded version of GFS server.
975 --- 2.0.18 2004/03/20
977 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
980 Ensure zlib.dll is packed with Windows install.
982 --- 2.0.17 2004/03/17
984 Fix encoding of xsd:string to use text instead of CDATA.
986 Fix endless loop in CQL parser with unbalanced ".
988 Use a more compact way to store MARC-8 conversion tables.
990 --- 2.0.16 2004/03/16 Debian only
992 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
995 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1000 --- 2.0.15 2004/03/01
1002 Another fix for decoding of XML packed records.
1004 --- 2.0.14 2004/02/25
1006 Fixes for Chunked encoding. White space not ignored after length spec.
1008 Update NS and use default NS for SRW diagnostic elements.
1010 --- 2.0.13 2004/02/23
1012 Implement ZOOM_resultset_cache_reset which resets record cache.
1014 Implement ZOOM_resultset_sort which sorts a result set.
1016 Implement chunked HTTP transfer.
1018 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1020 --- 2.0.12 2004/02/16
1022 Added member 'schema' to bend_explain_rr structure so that backend
1023 can specify explain record identifier. Defaults to Zeerex 2.0.
1025 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1027 --- 2.0.11 2004/02/16
1029 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1032 Added init command for yaz-client which sends "extra" init request.
1034 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1035 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1037 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1039 Make ZOOM error code for "invalid query".
1041 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1043 --- 2.0.10 2004/02/05
1045 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1048 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1050 Added option -p <file> to make Generic Frontend Server to write PID file.
1052 Added option -D to put Generic Frontend Server in background on its own.
1054 Make ZOOM C recognize option "password". If unset, "pass" is used
1055 (for backwards compatibility).
1057 Fixed a bug in Generic Frontend Server that could make it crash if a
1058 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1061 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1062 Must be issued before open, in order to be in effect.
1064 --- 2.0.9-6 2004/01/12 Debian/Windows
1066 Make the SRU server more picky WRT unknown params, etc.
1068 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1070 New YAZ client command, options, that sets Z39.50 options.
1072 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1073 options from a string of tokens (one token for each option bit).
1075 Update SRW diagnostic code messages.
1077 --- 2.0.9-5 2004/01/07 Debian/Windows
1079 Handle user defined stylesheet for SRW/SRU.
1081 --- 2.0.9-4 2004/01/06 Debian/Windows
1083 Fix bug in decoding of Content-Length.
1085 --- 2.0.9-3 2004/01/06 Debian/Windows
1087 Fix a bug with decoding of XML packed records.
1089 --- 2.0.9-2 2004/01/05 Debian only
1091 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1093 Fix bug in SRW/SRU diagnostics decoding.
1095 --- 2.0.9 2004/01/05
1097 Fixed bug in Generic Frontend Server which could drop records exceeding
1098 preferred message size. Reported and fixed by Irina Dijour.
1100 Fixed calculation of package size for structured records in Generic
1101 Frontend Server. Reported and fixed by Irina Dijour.
1103 Fixed namespace for SRW/SRU diagnostics.
1105 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1107 --- 2.0.8 2003/12/22
1109 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1110 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1113 CQL changes to reflect recent changes to the specification:
1114 * Documentation talks about context sets instead of index sets.
1115 * Documentation talks about indexes instead of qualifiers.
1116 * The CQL-to-PQF transformer's configuration file now uses
1117 "index.set.name = <attributes>" instead of the old form
1118 "qualifier.set.name = <attributes>". (Both forms are still
1119 understood but the latter is deprecated.)
1120 * CQL terms with no explicit index specified are now interpreted as
1121 cql.serverChoice instead of srw.serverChoice (which of course
1122 behaves exactly the same.)
1124 --- 2.0.7 2003/12/16
1126 MARC conversion can now generate ISO2709 output in another
1127 character set. yaz-marcdump uses this facility if you invoke it
1130 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1131 functions from there can be used from C++.
1133 --- 2.0.6 2003/12/04
1135 Frontend server now transfers memory from decoded packages to stream
1138 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1139 references to show up.
1141 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1142 the ZOOM Abstract API. The older names for the same options are still
1143 also supported for the benefit of old applications.
1145 ZOOM-C supports "implementationId" and "implementationVersion" options
1146 to go along with "implementationName". These allow the user code to
1147 specify identification strings to be sent to servers.
1148 Add OID for the new ExtLite attribute set.
1150 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1151 as requested/supplid by Ere Maijala <ere@atp.fi>
1153 For generic frontend server, reverse the order of
1154 "toolkit-supplied / application-supplied" strings sent as implementationId,
1155 Name and Version. Also, remove the spaces around the slash. This brings
1156 the GFS in line with the behaviour of ZOOM-C on the client side.
1158 Add function ZOOM_scanset_display_term.
1160 yaz-client shows scan displayTerm if present.
1162 Utility yaz-iconv is now installed by default along with the man page
1165 Extend configure check for OpenSSL to use pkg-config where available (such
1168 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1169 server to specify uid/gid/mask for socket using the format
1170 unix:[user=uid,][group=gid,][umask=mask,]file=path
1171 If file= is omitted the existing format is assumed, e.g.
1173 in which case the mask is 0666 (rw for everybody).
1175 Major restructure of YAZ source. All source in libyaz is in src directory.
1176 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1177 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1179 Added man page for utility yaz-marcdump (used to be called marcdump).
1180 yaz-marcdump is installed by 'make install'.
1182 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1183 of incoming package failed.
1185 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1187 Change prototype of odr_perror: add const to message string.
1189 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1191 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1192 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1193 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1194 DNS lookup. There should not be any compatibility problems with this
1195 assuming that blocking=1 or 0 is used.
1197 Fix bad reference in UNIX comstack in function cs_addrstr.
1199 Fix for compilation on AIX.
1201 The generic front-end server (server/seshigh.c) now supports returning
1202 Init diagnostics to the client in User-information-field, in
1203 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1206 --- 2.0.4 2003/09/04
1208 Allow any CQL relation (not just all,any,exact,scr).
1210 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1211 that features the same UI.
1213 Implemented command update0 in YAZ client which is equivalent to
1214 update but uses old of Ext Update ASN.1.
1216 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1217 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1218 Previously no OID was used for this info.
1220 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1221 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1222 returns 'malformed search term' otherwise.
1224 SortResponse member resultCount now set to NULL in sort handler of
1227 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1230 Add three new utility functions for translating OIDs between various
1231 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1232 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1233 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1234 char *oid_to_dotstring(const int *oid, char *oidbuf);
1235 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1237 Reverted modifications for ES Update definition for z_IU0Update
1238 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1239 is back to YAZ 2.0.2.
1241 String value attributes for CCL parser.
1243 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1244 which their FirstSearch server returns in Init responses, sometimes
1245 carrying useful diagnostic information when Init fails. This has the
1246 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1247 "z39.50/oclcui.asn", where its definition is somewhat different from
1248 what OCLC document on their web-site, as required to interoperate with
1251 Support for anonymous authentication in yaz-client. Use the command
1254 * Fix the OID of the Index Data-local "admin" Extended Service from
1255 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1256 the 1000, which indicates a locally-defined OID, was a mistake.
1258 --- 2.0.3 2003/06/20
1260 Fix CCL directive @case handling so that it affects string match for
1261 both CCL keywords and qualifiers.
1263 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1264 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1265 Decoder has been updated with ASN.1 changes as listed in
1266 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1267 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1268 z_IUUpdate, remains unchanged.
1270 ZOOM_record_get may now return a record in a specific character set.
1271 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1272 "from" is the character set of record as returned by target. "to" is
1273 the character set to be returned. If omitted, "to" is UTF-8.
1275 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1277 New ODR utility, odr_getelement, which returns name of element for
1278 which encoding/decoding failed.
1280 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1281 in cases where a required element was omitted.
1283 Bug fix: some MARC8 sequences were not converted.
1285 New ZOOM option "step" which specifies number of records to be
1286 retrieved in one chunk. Used in conjunction with "start" and "count".
1288 SRW support for yaz-client. Use scheme http: to use it, e.g.
1291 yaz-client no longer does (un)intelligent character set conversions
1292 by default. Can be enabled with charset and marc_charset commands.
1294 xmalloc trace fix for 64-bit systems such as DEC alpha.
1296 Solaris 2.6 compile fix.
1298 New function, cql_strerror() translates SRW error codes, as returned
1299 by cql_transform_error(), into human-readable English strings. Used
1300 in yaz-client diagnostics when appropriate.
1302 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1303 converts it into a type-1 query which is sent to the server. This
1304 makes CQL available for use with all Z-servers, as opposed to the tiny
1305 minority that can handle CQL queries themselves.
1307 --- 2.0.2 2003/04/28
1309 New Debian package layout similar to the Redhat Package layout.
1311 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1312 and search result respectively.
1314 --- 2.0.1 2003/04/25
1316 Redhat package is now several packages: libyaz (runtime libraries),
1317 libyaz-devel (development and documentation, and yaz (utility programs).
1318 Package spec file by Morten Bøgeskov.
1320 New member 'schema' in struct bend_fetch_rr which the name of requested
1321 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1322 handler MAY set this to reflect the schema of the returned record.
1324 New member 'display_term' in struct scan_entry. GFS now sets member entries
1325 and allocates scan entries to be filled by user scan handler. In previous
1326 version, entries member was allocated by the scan handler. That still works,
1327 but the GFS will ignore member display_term - assuming it was NOT set by
1328 the handler. The fact that the GFS now allocates the entries both allows
1329 for new members and makes a scan handler easier to write.
1331 Fix CQL lex buffer overflow.
1333 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1334 SRU default recordPacking is string.
1336 SRU protocol support for frontend server.
1338 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1340 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1342 Added scan for the ZOOM shell (zoomsh).
1346 * String Identifers for Schemas (Amendment 5).
1347 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1348 Old definition for schema
1349 Odr_oid *schema; /* OPT */
1354 Z_InternationalString *uri;
1355 #define Z_Schema_oid 1
1356 #define Z_Schema_uri 2
1359 * resultCount parameter to Sort Response (Amendment 1).
1360 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1362 Support for SRW 1.0 over HTTP. This is an optional feature and
1363 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1366 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1367 on the same port. SRW SearchRetrieveRequests are mapped
1368 to bend_init,bend_search,bend_fetch,bend_close.
1370 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1372 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1373 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1375 ZOOM connections are SRW based if schem http is used for hostname
1376 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1377 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1379 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1380 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1381 distance=n, order=true/false, relation=le, prox unit=word. If
1382 n is omitted, distance 1 is used.
1384 Fixed problem with C compiler include path in wrong order.
1386 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1387 on Solaris. Patch from Ko van der Sloot.
1389 New MARC decode API. All new functions operate on a yaz_marc_t
1390 handle. The most important new functions are: yaz_marc_create,
1391 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1392 decode and destroy respectively. Decoder can produce formats
1393 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1394 include/yaz/marcdisp.h.
1396 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1397 to UTF-8, UCS-32, wchar_t or Latin-1.
1399 * Prototypes for yaz_iconv_-functions moved to separate header
1400 include/yaz/yaz-iconv.h.
1402 Make a few private functions 'static' in unix.c. This prevents
1403 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1405 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1406 are set when Init Response is received.
1408 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1409 but returns diagnostic set as well.
1411 New function yaz_strerror which is a portable wrapper for
1412 strerror/strerror_r/GetLastMessage.
1414 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1415 is returned for MARC. If type is "oai", then OAI MARC is returned.
1417 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1420 --- 1.9.2 2002/11/26
1422 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1424 Fix bad race conditions on SIGTERM and terminate gracefully in
1427 Move retrieval (data1) module to Zebra since nobody seems to be
1430 Add GRS-1 render for ZOOM using same format as yaz-client.
1432 --- 1.9.1 2002/10/05
1434 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1436 Fix broken ESpec handling in data1 module.
1438 SGML reader parses comments and makes them part of the data1 tree.
1440 Added several type casts so that YAZ compiles as C++ code.
1442 ZOOM didn't handle PDU encoding failures properly.
1444 Added more Bib-1 diagnostics (approved extensions).
1446 GNU configure: better check for iconv.
1448 More portable use of accept, getpeername. Check for socklen_t. Use
1449 int/size_t if socklen_t is not defined.
1453 PQF parser rejects bad queries - including those with extra
1454 characters in them. PQF parser used to silently ignore that.
1455 Cleaner API for PQF added, which allows you to get detailed
1456 error information for bad queries (see yaz/pquery.h).
1458 Fixed bug in ZOOM_record_get for type "database".
1460 Implemented mini iconv library supporting conversions between
1461 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1463 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1465 --- 1.8.9 2002/08/20
1467 Fixed ZOOM C record cache so that preferredRecordSyntax and
1468 elementSetName is used to check for already fetched records.
1470 --- 1.8.8 2002/08/02
1472 Added three members in bend_initrequest structure to facilitate
1473 character set negotiation.
1475 Fixed a bug in frontend server that could cause indefinite
1476 loops under rare conditions.
1478 Revised character set utilities (charneg.h) so that encoding
1479 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1481 For PQF, directive @term <type> sets term type for Scan/Search.
1482 Here <type> is general, string, numeric, null. The term type
1483 is inherited - just like @attr.
1485 New call odr_set_charset that sets character set conversion for
1486 international-strings on a ODR stream. Prototype is:
1487 int odr_set_charset(ODR o, const char *to, const char *from);
1488 The InternationalString is still represented as C string in YAZ
1489 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1490 won't). On the protocol level, you can use any encoding.
1492 Support for UNIX sockets in ZOOM.
1494 Solaris recv sometimes returns errno == ENOENT. It is treated as
1495 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1497 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1498 both client and server. Code by Morten Bøgeskov.
1500 --- 1.8.7 2002/05/22
1502 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1503 that they can be used directly from Visual Basic. You must recompile
1504 your windows APP if you're using ZOOM.
1506 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1507 Commands "lang" and "charset" sets language and character set respectively.
1508 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1509 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1511 Attributes from multiple CCL fields may be OR'ed rather than merged
1512 using directive "@field or". Fields are still merged by default -
1513 equivalent to "@field merge".
1515 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1518 Fixed bug in zget for parameter ExtendedServicesResponse.
1522 --- 1.8.6 2002/03/25
1524 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1526 Client displays USR.1:SearchResult-1 (hits per term).
1528 Additional Search Info for search in Generic Frontend Server.
1530 Fixed CCL parsing of "field=s".
1532 WIN32 installer - using the excellent NSIS software from nullsoft.
1534 Fixed CCL parsing of "field = - <number>".
1536 Added function yaz_marc_decode that decodes MARC for line mode
1537 display or XML (similar to that used by JZKit).
1539 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1540 Z39.50. But ISO/ILL was, however.
1542 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1543 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1545 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1546 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1548 --- 1.8.5 2002/02/03
1550 New YAZ client features: Command completion and new commands:
1551 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1552 Code provided by Jacob Poulsen.
1554 New call oid_trav, that visits all registered OIDs via callback.
1556 Function ZOOM_record_get now returns const char pointer rather than
1557 void pointer. It saves a lot of type casts.
1559 For YAZ client, command "auth" now allows you to set authentication
1560 in IdPass style. It is enabled when three tokens are given - order
1561 is user, group and password.
1563 Fix memory leaks in MARC record handling for ZOOM.
1565 New option for YAZ client, -k <kilobytes> that sets
1566 maximum record size. Similar to -k option for generic frontend
1567 server and yaz-ztest.
1569 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1571 Prefix query parser reports "fail" when bad attribute set is given.
1573 Fix in MARC decoder. Proximity logging. Fix for attribute set
1574 in scan handler for server. Patches by Shigeru Ishida.
1576 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1579 Configure option --with-openssl=<dir> now works when a directory is
1580 specified. Patch provided by Morten Bøgeskov.
1582 New option for YAZ client, -u <auth>, that sets authentication.
1584 ZOOM fix: error information was sometimes "missing", since error
1585 was cleared/reset too when it shouldn't.
1587 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1589 --- 1.8.4 2002/01/04
1591 Scan for ZOOM API. New object ZOOM_scanset. New functions
1592 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1593 ZOOM_scanset_destroy.
1595 New ZOOM function, ZOOM_connection_last_event, that returns type
1596 of last event (such as "receive data", "send data", "apdu received",
1599 New ZOOM option, schema, that specifies schema for retrieval.
1601 New CCL feature. Qualifiers can be aliases for one or more
1602 other qualifiers (if more than one is given, OR is used).
1604 ZOOM uses named result sets if target supports it.
1606 Two new YAZ client commands: . (dot, which sources a script of YAZ
1607 client commands), and ! (to execute shell command.). Implemented
1610 Working on Debian packages.
1612 --- 1.8.3 2001/11/19
1614 YAZ client enables named result sets only if target supports it.
1616 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1618 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1619 with key="host" to get same result.
1621 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1622 Function Z3950_resultset_record(s) returns references to records
1623 "owned" by resultset. To become owner use Z3950_record_clone.
1625 Function z_ext_record handles Extended Services. Thanks to
1628 --- 1.8.2 2001/11/12
1630 CCL Parser fix: ignore token comma when dealing with and-lists.
1632 Documentation updates for COMSTACK.
1634 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1635 Changed prototype Z3950_records. For some functions, int parameters
1636 were changed to size_t.
1638 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1641 New MARC decode/display function, marc_display_exl, which properly rejects
1642 non-ISO2709 records. YAZ client uses it.
1644 --- 1.8.1 2001/10/29
1646 Fix bug: local attribute set wasn't set correctly in PQF strings.
1650 * Old Z39.50 codecs no longer supported.
1652 Added ZOOM C binding. See http://zoom.z3950.org/
1654 Renamed states for COMSTACKs to avoid confusion with events.
1656 Implemented cs_look and proper cs_rcvconnect.
1658 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1660 Configure detects POSIX threads on OpenBSD.
1662 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1663 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1665 When error is returned from present handler, non-surrogate diagnostic
1666 is returned in present response (and fetch handler is no longer called).
1668 * Minor adjustments to pquery parser (PQF). Token characters may be
1669 escaped by using backslash (C-style).
1671 PQF parser allows string attribute values to be specified. For @attr,
1672 non-numeric characters after the equal-sign are treated as strings
1673 (e.g. @attr 9=title).
1675 CCL trunction character may be defined (@truncation in file)
1677 * function zget_ExtendedServicesRequest sets waitAction to
1678 waitIfPossible (was wait).
1680 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1683 CCL operator names may be set in field definition files (CCL_bibset).
1684 See ccl/bib1 for an example.
1686 Fixes in ASN.1 compiler for C++ compatibility.
1688 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1689 and "op_or" to avoid conflict with C++.
1691 Fixed problem with GNU readline detection on Redhat 7.0.
1693 Added step-size for Scan backend handler.
1695 Fixed bug that made the frontend server crash when no attribute
1696 set was specified for scan.
1698 Front-end server automatically switches to original working directory
1699 when installed as an NT service. Previously -w had to be specified to
1702 Added extended attributes for retrieval module (data1), so that data1
1703 records carry d1_readXML/SGML attributes. d1_read also supports
1704 null-data rules ( <tag/>)
1706 On UNIX when POSIX threads are available, a separate library libyazthread
1707 is created. Programmers should link with that library and the yaz library
1708 when using threads. The reason for the split was that some applications
1709 on Linux, such as Apache, doesn't work well when using shared objects that
1712 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1713 (or any frontend server) in SSL mode by specifying ssl: followed by
1714 address. Only tested on UNIX.
1716 Added feature for CCL module. Virtual structure s=al or s=ol generates
1717 and-list and or-list respectively instead of phrase search.
1721 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1722 log_mask_str. This was done to avoid name conflicts with other libraries
1723 (such as other PHP extensions).
1725 Added raw OID member for preferred record syntax (request_format_raw)
1726 and returned record syntax (output_format_raw) for backend fetch method.
1728 Config file yaz-config now accepts options so that it returns specific
1729 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1731 Shared library support for UNIX using GNU libtool.
1733 * Modified backend interface. Request/Response struct's replaced by
1734 one read/write C struct. For example bend_fetchrequest and
1735 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1736 Every handler - even search has to be registered in bend_init
1737 handler. This means that the YAZ library no longer refers to
1738 external functions and it makes it possible to make the whole
1739 thing a single DLL/SO.
1741 Added Segment handler for backend server.
1743 Added Zmbol/Zebra administrative functions to YAZ client.
1745 Threaded frontend server on UNIX (when POSIX Threads are available).
1746 Starting the server with option -T enables multi-threading.
1750 Added configure option --enable-comp/disable-comp to control use
1751 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1752 located in sub directory asn.
1754 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1755 in ${exec_prefix}/bin along with the other programs yaz-client and
1758 GNU automake used to maintain makefiles.
1760 Added several OID's.
1762 Changed retrieval module so that we can load records with no abstract
1763 syntax defined. Tagpaths in these records are fully composed of string
1766 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1770 On UNIX, the generated makefile now supports a proper 'make install'.
1771 The prefix can be set via GNU configure to set the install location
1772 (default is /usr/local).
1774 * YAZ programs client and ztest were renamed to yaz-client and
1775 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1776 locations, such as /usr/bin,/usr/local/bin,etc.
1778 * YAZ Header files were moved from include to include/yaz. YAZ Header
1779 files are referred to as include <yaz/log.h> rather than <log.h>.
1780 The YAZ include path (-I ..) is therefore the same as before. Programmers
1781 should update their #include statements or use -Ipath/include/yaz
1782 instead. The main motivation for doing this change is that YAZ header files
1783 can be installed in "standard" locations /usr/include,/usr/local/include
1784 without introducing conflicts, since ALL YAZ header files are stored
1785 in subdirectory yaz (under /usr/include for example).
1787 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1788 rather than project/workspace files. We switched because project files
1789 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1792 Changed name of logging function, logf, to yaz_log, to prevent name
1793 clash with some math-log functions. The YAZ header log.h defines logf
1794 to yaz_log (#define) so there should be no incompatibilities by this
1797 Added bend_start/bend_stop handlers for server. These handler are
1798 called on start/stop of server. For windows they are called whenever
1799 a service is started/stopped.
1801 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1802 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1803 in util/yc.tcl. The auto-generated C code structures are, in a few
1804 cases, incompatible with the old decoders. There are differences in the
1805 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1806 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1807 The preprocessor variable ASN_COMPILED is defined when the compiled
1808 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1809 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1810 wish to use the old encoders/decoders you can specify --disable-yc
1813 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1814 version so that it supports both new - and old version of DB Update
1816 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1817 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1818 change. The name parameter can be set to 0 in which no name is specified
1819 for the construction. The macros odr_implicit and odr_explicit sets name
1820 parameter to zero for the construction involved. New macros
1821 odr_implicit_tag and odr_explicit_tag are similar to the others,
1822 except that a name parameter is added. For programmers' that don't use
1823 ODR they probably only need to change the call to z_APDU and z_External.
1825 Added access control facility by interfacing the TCP wrapper library.
1826 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1827 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1828 name of the daemon and enables the access control as specified in
1829 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1831 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1832 den Dool <H.M.vdnDool@kub.nl>.
1834 Added reference ID parameter to most functions in server API - refer
1835 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1837 Changed name of ccl library to libccl.a (was ccl.a).
1839 Fixed bug in decoder for Explain (Category TargetInfo).
1841 Added support for GNU readline in client. Thanks to Jacob Poulsen
1842 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1844 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1845 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1846 IMPLEMENTATION! This change was made to the development version before
1847 the ZIG decided to retract the amendment. If any users MUST be
1848 compatible with the original Update definition, PLEASE CONTACT US, and
1849 we will include a separate definition corresponding to the old Update
1850 ES. Note that because of the change to the ASN.1 of the
1851 TaskPackageRecordStructure we cannot define a single structure that
1852 will support both versions.
1854 * Added const modifier to buffer parameter for some ODR/BER encoding
1855 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1856 completeWAIS, odr_dumpBER.
1858 Fixed bug in client.c which caused a crash when a scanResponse didn't
1859 contain positionOfTerm.
1861 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1862 * will cause an error in a client if a non-YAZ target sends both a
1863 * list of Scan entries and non-surrogate diagnostics.
1865 Retrieval module enhancements. Tag sets may be typed in the reference
1866 to it. From the .abs-file the "tagset" directive takes a third optional
1867 integer type for the tag set referenced. From a .tag-file the "include"
1868 directive takes a third optional type as well. The old "type" directive
1869 in the tag set itself is still recognized but acts as the default type
1872 Backend interface change. Individual Scan terms returned from bend_scan
1873 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1874 in include/backend.h.
1876 Retrieval module enhancements. Multiple tag sets and attribute sets may
1877 be specified in abstract syntax specs. Revised the error/warning for
1878 logging messages reported by the retrieval module when reading the
1881 Object Identifier system (oid_..) changed. The API is backwards
1882 compatible but the oid-routines now allocates new OID's when needed.
1883 Raw OID's may be specified in oid_getvalbyname.
1885 YAZ now uses GNU configure to generate Makefile(s).
1887 * Minor changes in some of the member names of DeleteResultSetRequest and
1888 DeleteResultSetResponse. See include/proto.h.
1890 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1891 and added member 'languages' in TargetInfo (which was missing).
1893 Changed the way attribute sets are handled in the retrieval
1894 module. These are now cached, just like the abstract syntaxes
1897 Changed YAZ so that it links with compiled ASN.1.
1899 Added Explain-schema definitions and mapping routines. The following
1900 Explain categories have been implemented: AttributeDetails,
1901 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1903 Fixed minor bug in Windows version of Server Library.
1905 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1907 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1909 Added EXTERNAL: UNIverse Resource Report (non-standard).
1911 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1912 ENUMERATED and SET OF.
1914 * Added 'const' to some of the char pointer arguments for the
1915 functions, data1_read_node, data1_getelementbytagname,
1916 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1919 Fixed bug in data1_insert_taggeddata - the last_child member of
1920 parent wasn't initialised.
1922 * Changed data1_read_record and data1_read_node so that the supplied
1923 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1924 doesn't refer to any parts of the "SGML"-buffer.
1926 Fixed bug in server library (Windows version of statserv_remove).
1928 * Changed code so that it compiles as C++. The type definition
1929 of Odr_fun which is a member of Odr_arm was changed. The result is,
1930 that an explicit typecast is needed for the fun pointer when
1931 using Odr_arm - as in:
1932 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1934 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1936 Implemented the new structured date and time definition as approved
1937 by the ZIG. Added schemaId element to the specificTag in Espec-1
1938 (also approved at the last ZIG). Thanks to RVDM.
1940 Added some Object identifiers (RVDM).
1942 Changed the Update Extended Service (RVDM).
1944 Added command "refid" to client which specifies referenceId for
1945 the following requests.
1947 Implemented extended service handling for server. See ztest.c
1948 for an example as well as backend.h. New handlers are registerd
1949 in the Init handler.
1951 * Changed interface for sort in server.
1953 Added new members to statserv_options_block. It allows a server
1954 to read options from another source than just the command line. Thanks
1955 to Charles Woodfield.
1957 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1958 renamed to zboolean. Some C++ compilers complained about the name.
1960 Minor changes to gils.abs. Added index 's' (sort) on title
1961 and date/time-last-modified.
1963 --- 1.4pl2 1998/1/30
1965 Fixed bug in server library regarding inetd mode (-i). This bug
1966 was introduced by release 1.4.
1968 --- 1.4pl1 1998/1/29
1970 Added sort facility in client and backend server interface.
1972 Fixed problem with dependencies in Makefile(s).
1974 Fixed bugs for encoders/decoders of extended services and
1977 Implemented sub-tree feature for schemas. Sub-trees are
1978 referenced in *.abs-files. See explain.abs for an example
1979 of the use of this feature.
1981 Modified bib1.att; local attributes for ANY didn't include
1982 ANY itself (only affects use of the retrieval module).
1984 Fixed bug in plain SGML reader in function data1_read_node:
1985 tags with prefix "var" was incorrectly interpreted as variants.
1987 Added feature "sub-schemas" to enable references to - and definitions
1988 of - group of elements.
1990 * Removed member parent from type data1_element (in data1.h).
1992 Implemented function odr_nullval() that returns the value of
1995 * Removed member num_children from data1_node (in data1.h).
1997 Made NT service interface part of the server library. The
1998 function statserv_main uses the NT service when required and
1999 calls the statserv_start / statserv_close routines.
2001 Routine zget_SearchRequest and zget_PresentRequest fills
2002 resultSetName/Id member with "default" instead of "Default".
2004 Fixed memory leak in server. Request queue member wasn't freed.
2006 Fixed nmem_exit so that memory is freed.
2010 Revised the CCL parser utility to be thread safe.
2012 Added function, oid_ent_to_oid, to replace the function
2013 oid_getoidbyent, which is not thread safe.
2015 * Added nmem_init and nmem_exit to initialize and release
2016 NMEM resources. Function nmem_init should be called once in the
2017 initial thread before NMEM/ODR is used. statserv.c and client.c
2018 have been changed accordingly. The change was necessary to make
2019 NMEM thread safe. The NMEM memory pool is shared amongst threads
2020 in a process. Unix-based applications will still work fine without
2023 Added NT Services interface for the the Z39.50 (statserv) Server.
2024 Refer to the ztest.c source on the usage.
2026 Windows 95/NT port using MSVC5.0. Project files are included in the
2029 * Defined new 'global' handle for the retrieval (data1) system. The
2030 new handled, data1_handle, describes the state of the data1 system.
2031 This handle is passed as first argument to virtually all
2032 data1 related routines. The functions data1_create and data1_destroy
2033 creates and destroys a data1 handle respectively.
2035 Added ODR encode stream member to all backend request structures
2036 init, search, scan etc. This stream should be used to allocate all
2037 memory used for the response when thread safe operation is needed.
2039 Changed the comstack utility, cs_addstr, to be thread safe. The
2040 returned hostname string returned by the function is now part the
2043 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2044 function. The cs_straddr takes a COMSTACK handle as argument, so this
2045 function must be used after cs_create and before bind/connect.
2046 This function is thread safe.
2048 Moved test server to 'ztest' directory - generic server code still
2049 in 'server' directory.
2051 Made prefix query (pquery.c) utility thread safe.
2053 Added new function modifier YAZ_EXPORT to 'export' public DLL
2054 functions when using windows (see include/yconfig.h).
2056 Added definitions to the OID database (util/oid.c) (RVDM).
2058 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2060 Added call to ccl_rpn_delete in client program.
2062 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2063 release of RPN structure.
2065 Added support for C++, headers uses extern "C" for public definitions.
2066 With input from RVDM.
2068 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2069 Thanks to Ronald van der Meer (RVDM).
2071 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2073 Added support for private extensions to the OID database
2074 (oid_setprivateoids()). Thanks to RVDM.
2076 Added optional, physical ANY (key replication)
2078 Fixed null-reference problem in GRS-1 output filter.
2080 Proximity operator added to Prefix Query Format (PQF).
2082 In test client command "base" accepts multiple databases.
2084 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2088 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2090 Smallish bug-fixes in the new encoders/decoders (explain).
2092 Bug fixed in DeleteRequest.
2094 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2096 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2098 Added SOIF syntax (using private OID for now) to retrieval module and client.
2100 Added Update extended service.
2102 Added SearchResult-1 additional info structure.
2104 Added optional CCL (ISO8777) interpreter as separate module. Available
2107 --- 1.2 1996/6/10 (1st anniversary release)
2109 Added Summary record syntax. Lightly tested.
2111 Added OPAC record syntax. Untested.
2113 Added ResourceReport service encoders/decoders. Untested.
2115 Fixed bug in z_Unit - wrong tagging on unitSystem.
2117 Fixed bug in the DiagRecs decoder.
2119 Added options for max PDU size and session timeout to frontend-server.
2121 Added documentation of query-language parsers and other supporting utilities.
2123 [frontend-server] Added Attribute set to the bend_scanrequest API.
2125 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2126 surrogate diagnostics were generated.
2128 [retrieval] Allow multiple local values for attribute.
2130 [retrieval] Allow multiple attributes per element in .abs files. index type.
2132 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2134 --- 1.1pl2 1996/4/10
2136 Minor changes, mostly specific to Zebra's requirements (retrieval)
2140 Repaired bug in frontend server when running multiple listening
2141 endpoints in dynamic mode.
2143 z_External() now won't break if a known, ASN.1 value comes encapsulated
2144 in an octet-string. The value will pass through unmodified in an Odr_oct.
2146 Added a bit of code to the demo client to decode & display
2147 ASN.1-structured records represented in the octet-aligned branch of
2148 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2150 Added z_ext_getentbyref() to the ASN module. Doc updated.
2152 * Completed the SCAN definition in the ASN module. This may break SCAN
2153 code based on older YAZ-versions at compile-time. The fix is easy -
2156 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2157 under the SCAN definition. Remember to initialize this, server-people.
2159 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2160 that this does not extend to ODR and ASN.
2162 Comstack allows insertion of established socket (primarily for
2163 inetd-operation of servers). Doc updated.
2165 Front-end server can now start from the inetd in TCP mode. Doc
2168 --- 1.0pl4 1996/1/24
2172 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2173 the rank and record number.
2175 Adjustments to the frontend server.
2177 Fixed diagnostic BER dumper. It ignored the file argument.
2181 Various changes to retrieval module.
2183 Changed the union discriminators of the protocol files from enums to
2184 ints paired with #defines.
2186 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2189 *Changed operator in the RPN structure to 'roperator', again to avoid a
2192 Fixed problems in Explain decoders/encoders.
2194 --- 1.0pl2 1995/12/6
2196 Memory bug in log module fixed.
2198 --- 1.0pl1 1995/12/5
2200 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2202 Bug in Explain DatabaseInfo module fixed.
2204 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2208 The shift to v1.0 signals that we now consider the *core* functionality
2209 of YAZ reasonably stable (the core being more or less equivalent to
2210 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2211 tested (Explain not at all - though that will happen soonish).
2213 Minor changes to code to support Windows port.
2215 Various minor changes after we're getting to use GRS-1 & co. more.
2217 Added Espec-1 format.
2219 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2220 of the protocol and it cannot be selected when encoding (maps into 'string'
2221 when decoding). Needed to talk to some servers.
2223 Demo client can request simple element set names.
2225 Added Diagnostic Format encoders/decoders.
2227 Added simple Close handling to frontend server (no hooks for resource
2228 reporting yet), and demonstration client.
2230 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2232 --- 1.0b3 1995/08/24
2234 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2235 handled incorrectly when records were requested in the searchResponse. This
2236 will only affect you if you use the frontend-server.
2238 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2239 Test-client will ask for and print GRS1. Ztest will return dummy records
2242 Added Explain encoders/decoders to the service-level API. Untested.
2244 Added Extended Services: Item Order encoders and decoders to the Service-
2245 level API. Untested. We could use a recent copy of the pertinent bits
2246 of the ILL protocol to add those bits.
2248 Added diagnostic format 1 encoders/decoders to the service-level API.
2251 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2252 odr_cons.c, which causes a more correct output.
2254 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2255 was always set to 0 when no records were requested in the searchRequest.
2257 * Added better external-handling. This shouldn't harm old code that
2258 *encodes* externals. It can break code that looks for a
2259 'single-ASN1-type' representation, since those types that are known
2260 are now decoded immediately. Look at the SUTRS sample code in
2261 seshigh.c and client.c. Documentation updated.
2263 Handling of structured records in bend_fetchresponse. Length -1 marks
2264 structured record, type is deduced from format field.
2266 --- 1.0b2 1995/06/27
2267 Fairly quick maintenance release to add SUTRS support.
2269 Fixed handling of SUTRS records in the demonstration client.
2271 * Added format field to the bend_fetchrequest and bend_fetchresponce
2272 structures of the backend API (frontend server). When the record is
2273 returned, the value of the format field is mapped to an OID. The
2274 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2275 of the record. The special value VAL_NONE in the bend_request means
2276 that no specific format was requested by the client. Documentation
2277 updated accordingly. Test server (ztest) will return a fixed dummy
2278 SUTRS record if your client requests SUTRS.
2280 Documentation updated accordingly.
2282 You can now set external libraries and RANLIB support in the top-level
2286 First public release.
