3 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
4 from ZOOM_record_error).
6 ZOOM C function ZOOM_record_get returns record schema for type="schema".
8 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
10 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
12 Better SRW-to-Bib-1 diagnostic mapping.
14 ZOOM C and yaz-client announces SRU version 1.2 by default.
16 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
19 Fixed in yaz_sru_decode to allow other version than 1.1.
23 Added support for SRU scan for ZOOM.
25 Added support for the use of the older versions or Extended Service
26 Update in ZOOM. To faciliate this, an option "updateVersion" may be
27 set to the version , 1=first, 2=second, 3=third. The third version is
28 what ZOOM C has used so far. And that, obviously, is the default.
30 Added support for CCL queries in Z39.50 queries sent to the GFS (and
31 therefore in Zebra and in SimpleServer-based applications). The new
32 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
33 qualifier file used to transform incoming CCL queries into Type-1 RPN,
34 which is passed into the back-end search callback function.
36 Added support for HTTP Basic authentication in clients: the SRU/W
37 codec encodes the username/password elements of the PDU structure
38 appropriately, and these may be set using the "user" and "password"
39 options in ZOOM-C applications (the same options that are used for
40 Z39.50 authentication).
44 Fixed bug #1208: SSL appears to be broken in ZOOM.
46 Fixed bug #1206: Libxml2 include path weirdness.
48 Added oid_name_to_dotstring.
50 Allow elementSetName to be specified for ZOOM C record update.
52 Allow waitAction to be specified for ZOOM C based for Extended Services.
54 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
55 syntax OID. Bug introduced in YAZ 3 series.
57 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
61 Fixed bug #1157: yaz-client does not read .yazclientrc from current
62 directory. yaz-client now reads commands from file given by option -f
63 if specified; then tries to read .yazclientrc in current directory.
64 Failing that, it reads .yazclientrc from user's home directory.
66 Added support for correlationInfo Note and ID for Record Update via
69 Added yaz-client command querycharset which specifies character set for
70 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
71 (termListAndStartPoint).
73 Charset ISO5428:1984 is an alias for ISO5428-1984.
75 Implemented a way to perform scan in a result set using Z39.50. This
76 is achieved by attaching the result set name in the characterInfo
77 (type InternationalString) of OtherInformation in the Scan Request PDU.
78 The result set is identified in the otherinformation by the new OID:
79 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
80 This allows for scan in result set and faceted search . Zebra did some
81 of this in the APT term using attribute type 8 and value being result
82 set. Using the OtherInformation approach for this is cleaner and easier
83 to work with in proxies and the like. This facility can be used in
84 yaz-client using new command setscan which takes a result set as first
85 argument, start position (APT) as second.
87 Changed decoding of SRU XML packed records to deal with servers that
88 have recordData with XML data with multiple root nodes. Also make
89 comparison for recordPacking case insensitive. Again, one server
90 returns "XML" where others return "xml".
92 For SRU responses allow Content-Type application/xml as well as text/xml.
96 Fixed bug in character set conversion of BER strings. Bug introduced
101 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
103 For OID class, use oid_class consistently.
105 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
108 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
109 character set for bibliographic information interchange". By Giannis Kosmas.
111 Added documentation on new OID API.
115 Changes to generic frontend server interface: added new member
116 'query_charset' for bend_initrequest structure. A backend init handler
117 should set this member to its native character set for query terms.
118 When defined, the frontend server logic will announce this character set
119 to a client if the negotiationModel bit is set by the client. All server
120 implementors are encouraged to specify this. If a backend server does not
121 specify this a warning is issued using yaz_log(YLOG_WARN,..).
123 Added CCL utility to remove terms (stop words) from resulting RPN
124 tree. This is handled by functions with prefix ccl_stop_words_ .
126 New ZOOM C option, "rpnCharset", which allows client-side conversion of
127 terms in RPN queries.
129 Clean-up the CCL API. Moved some internal structures from ccl.h to
130 private header cclp.h. Changed ccl_parser_create so that a Bibset must
131 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
132 This is replaced by ccl_parser_find_str which takes a string instead.
134 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
135 libyaz.la is the core of YAZ except the generic frontend server and
136 does not depend on POSIX threads anymore. libyaz_server.la is the
137 generic frontend server facilities and uses POSIX thread functionality
138 if available. The libyaz.la no longer depends on POSIX threads because
139 the number of global structures is limited. NMEM no longer re-uses blocks
140 between threads ; it simply free's memory immediately but allocates in
141 "large" chunks as usual. We don't expect any performance penalties
142 because of this. The yaz_log system is still using a global log_level so
143 caution must be taken when modifying it with yaz_log_init_.. +
144 yaz_log_mask_str. This, however, should not cause any trouble because
145 these functions are called during initialization of application code
146 anyway. `yaz-config --libs server` returns libs for server applications;
147 `yaz-config --libs` returns libs for non-server applications.
149 New OID database - with public definitions in oid_db.h. Removed old OID
150 database including the head oid.h and definitions such as enum oid_value
151 and struct oident. The new OID database uses the same string names as
152 before but the 'protocol' is gone. There are now only two representations
153 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
154 converts from string to OID; functions with prefix yaz_oid_to_string
155 converts the other way.
157 Change to emit_term() in CQL-to-PQF query translation: when a term has
158 the /regexp relation modifier, do not process it for leading and
159 trailing "^" and "*", which have quite different meanings in regular
162 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
163 write handlers no longer carries a 'last' parameter. This will make
164 yaz_iconv flush "less" characters. A flush is performed by call to
165 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
167 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
168 removed, because function yaz_query_to_wrbuf does the same.
170 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
171 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
173 Deprecated MARC utility functions removed.
175 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
178 Branch split: YAZ_2_1_55_branch
180 --- 2.1.54 2007/03/16
182 Fix to ZOOM-C so that transparent reconnection is properly handled on
183 connections that are in asynchronous mode.
185 Fixed compilation on OpenBSD 4.0.
187 Large strings in GRS-1 records are now properly displayed in yaz-client.
189 Added character conversion support for "advancegreek"; based on patch from
192 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
193 sequence is met. Before the error was not set so it would be unknown.
195 Adjust yaz-marcdump MARC reader so that it skips until record separator
198 --- 2.1.52 2007/03/07
200 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
201 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
202 fd_set structure used as a bitmask for the FDs to be selected on.
204 Using ACX_PTHREAD macro to check for POSIX threads.
206 Fixed have-vsnprintf check.
208 --- 2.1.50 2007/02/23
210 Fixes for configure on BSD. Bug #900.
212 Added snprintf/vsnprintf wrappers for systems that don't have
213 limits (heavens forbid).
215 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
216 created before all previous tasks were completed and removed from the
217 task queue, the new task could be removed by a mistake.
219 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
221 Implemented pass-through CQL-to-PQF conversions. Bug #861.
223 Fixed bug #832: Problem with MARC/charset in yaz-client.
225 Fixed bug #668: save command line history for yaz-client.
227 Fixed bug #830: pkg-config support.
229 --- 2.1.48 2007/01/23
231 Extended ZOOM result set options with two options that may be read by
232 a client: resultSetStatus and presentStatus with values as specified for
234 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
236 Fixed bug #827: Using SSL fails on Debian etch.
238 Fixed bug #826: Weird looking chars for set of MARC records.
240 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
241 that is treated as an ItemOrder with itemRequest being an XML document
242 external. The value of "doc" is the content.
244 Extended the GFS search facility. New member of bend_search_rr
245 'estimated_hit_count' signals that hits is known to be an estmate
246 (higher or lower than real hit count). New member 'partial_resultset'
247 signals that the search was partial (hit count is lower or equal than
248 real hit count). For Z39.50, the information is stored in resultSetStatus
249 member of SearchResponse APDU. For SRU, the information is signalled
250 via SRU diagnostic 59: "Result set created with valid partial results
253 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
255 --- 2.1.46 2007/01/13
257 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
259 Added ZOOM_connection_peek_event.
261 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
262 the following new functions:
263 ZOOM_event_nonblock, ZOOM_connection_process,
264 ZOOM_connection_get_{socket,mask,timeout},
265 ZOOM_connection_fire_event_{timeout,socket}.
266 The existing blocking event handler, ZOOM_event, is a wrapper for the
267 + blocking ZOOM_event_sys_{poll,select}.
269 Implemented function ccl_xml_config which parses XML version of CCL
270 configuration (bug #798).
272 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
274 Added timings utility (yaz/timing.h)
276 --- 2.1.44 2007/01/03
278 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
281 Fixed bug #779: Rotation of apdu.log fails.
283 Fixed for character set conversions:
284 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
285 Honor G1 set in MARC-8 decoding.
287 --- 2.1.42 2006/12/17
289 Fixed bug #775: char conversion does not handle Alternative UTF-8
292 Implemented function yaz_marc_read_line which parses MARC line format
293 records. There is a wealth of formats out there. So far, this function
294 reads line records produced by yaz_marc_write_line.
296 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
297 more generic and easier to remember(!) options: -i format and -o format
298 which specifies input format and output format respectively - where
299 format is one of "marc", "marcxml", "line", "marcxchange".
301 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
302 does not print anything except warnings for records.
304 For yaz-marcdump, added support for MARC split into files (-s) with a given
307 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
308 spec, at http://www.loc.gov/standards/sru/record-update/
309 This has changed the binary layout of the following structs:
310 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
311 bend_update_rr . Patch by Ko van der Sloot.
313 Added GFS utility function bend_assoc_is_alive which returns 1 if
314 association is still alive (client is connected); 0 otherwise (client
315 closed connection). This allows busy servers to stop working for
318 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
319 been a separate piece of software. This version of ziffy has been modified
320 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
322 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
324 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
325 Client code may now interrogate options such as "init_opt_sort" to
326 find out whether the server claims to support various options.
328 --- 2.1.40 2006/11/27
330 Added utilities yaz_{set,get}_esn to set/get element set name from
333 Removed the build of libyazthread.la. The libyaz.so is the threaded version
334 of YAZ and has been so since YAZ 2.1.10.
336 Implemented ZOOM_record_error which returns error information for
337 record (surrogate diagnostic).
339 --- 2.1.38 2006/10/31
341 Updates for SRU Update by Ko van der Sloot:
342 1. Changed name from "operation" to "action"
343 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
344 versions in the code, marked as 'backward compatible'.
345 3. Added diagnostics for SRU Update.
347 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
349 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
351 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
353 For GFS, fixed problem with SRU diagnostic 'First record position out of
354 range' being issued for 0 hits.
356 zoomtst10 part of Windows Build.
358 --- 2.1.36 2006/10/13
360 Implemented yaz_filepath_comp which splits a path into file path
361 components (required by Zebra 2.0.3+).
363 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
364 BSD inspired license until now so this should not have any real impact on
365 anybody. See http://www.opensource.org/licenses/bsd-license.php
367 Fixed bug #687: Missing log lines.
369 Fixed bug #678: CQL to PQF translation does not preserve double-quote
372 Fixed bug #689: SRU diagnostics to be added.
374 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
375 whether a connection is idle (no more work do do).
377 --- 2.1.34 2006/10/04
379 Change type of optval from long to int for invocation of setsockopt with
380 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
382 Added support for specifying the max log file size for the Generic
383 Frontend Server. The size is given with option -r.
385 --- 2.1.32 2006/09/21
387 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
389 --- 2.1.30 2006/09/17
391 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
394 Fixed bug in Generic Frontend Server that could cause a server to stop
395 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
397 For the generic frontend server, the maximum record size is used as maximum
398 size of incoming packages (SRU + Z39.50). The value until was previously
399 only used in Z39.50 Init negotiation and, later, in a session controlled
400 sizes of records returned. This is controlled using -k option. It can be
401 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
403 --- 2.1.28 2006/09/04
405 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
408 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
410 New option for yaz-marcdump -lpos=value which allows setting a portion
411 of MARC header to a certain value.
413 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
415 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
416 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
418 --- 2.1.26 2006/08/15
420 Fixed problem with SRU mode type (soap, get, post) for yaz-client
423 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
425 --- 2.1.24 2006/08/08
427 Fixed MARC ISO2709 encoding routines to deal with character set
430 Minor changes to GFS logging. Database included in search request log
433 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
434 cached/multiple records.
436 Shared libraries are built by default on Unix+configure.
438 Changed cql2pqf transformation to use a different evaluation order. The
439 new order is: always, relation, structure, position, truncation, index
440 and relationModifier. Old order was: always, relation, relationModifier,
441 structure, index, position, truncation. Note that the the latter ones
442 override former ones for identical attributes.. The new scheme means that
443 it is possible to override any existing attribute with a relationModifier.
444 And also that it is possible to override everything for the index rule
445 (except the ones listed in relationModifier). No order is perfect but this
446 one, we believe, covers more real cases.. The "always" should have been
447 called "default", since the attributes there can be overridden with all
450 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
451 compilation phase, but also for yaz-config --cflags output. This allows
452 us to have public headers with Libxml2 stuff in them . It should also,
453 eventually, make Libxml2 checks redundant in packages using YAZ, such
456 --- 2.1.22 2006/06/15
458 Changed SRU update structure bend_update_rr so that SRU diagnostics are
459 stored in uri, message and details.. Previously diagnostics were stored
460 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
461 compatibility.. but he's probably the only one affected, so.
463 Added support for CCL, compiled on the client side, in ZOOM-C. This
464 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
465 input; the resulting query objects can be used for for searching with
466 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
468 YAZ' configure searches for OpenSSL by default.
470 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
471 SL_CTX_use_certificate_file. See
472 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
473 for more info. Thanks to Ko van der Sloot.
475 --- 2.1.20 2006/06/02
477 Bug #600: SRU GET, POST support for yaz-client. Introduced
478 command 'sru' which selects method SOAP/GET/POST.
480 Allow missingValueAction to be specified for the sortspec string -
481 function yaz_sort_spec. By default, the missing value action is null.
482 Use ! to specify "abort". Use = followed by stringvalue to specify default
485 Ensured that Present-handler (if defined) is called in GFS before any call to
486 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
487 searchRetrieve requests.
489 Documentation for YAZ is now based on the Docbook XML/XSLT using
490 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
491 is no longer depending on jade/openjade or docbook-to-man scripts.
492 PDF is no longer part of the distribution - but can optionally be
493 made using DSSSL/jadetex or FOP.
495 Added retrieval handling support in Generic Frontend Server to support
496 conversion between MARC/XML as well as XSLTtransforms. See
497 etc/yazgfs.xml for an example.
499 Added Authentication support to Generic Frontend Server in SRU
500 mode. Authentication using HTTP Basic is supported, as is the use
501 of 'x-username' and 'x-password' parameters in the request itself.
503 Added support for a new character set MARC8s identical to MARC8 except
504 that it converts combined characters to single Unicode characters in the
505 Latin-1 range (when possible).
507 --- 2.1.18 2006/04/24
509 ASN.1 compiler 0.4: generates brief Doxygen file header for
510 generated .h/.c files.
512 Utility yaz_iconv now supports conversion to MARC-8.
514 New facilities for the MARC module. The reading - and writing of
515 content are separate methods for the yaz_marc_t handle. The following
516 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
517 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
518 format). Write functions have prefix yaz_marc_write_.. The existing
519 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
520 available. Removed support for OAI-MARC and simplexml (not the
521 simplexml from PHP5).
523 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
524 to be returned for this connection.
526 --- 2.1.16 2006/03/31
528 Allow multiple languages and charsets to be specified with
529 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
530 negcharset iso-8859-1,utf-8
532 Translation of proximity nodes from CQL into PQF now works.
534 Moved to automake 1.8, 1.9.
536 Added function yaz_log_set_handler which allows a log handler to be
537 installed. This handler will be called for all log messages. Output
538 to file is also produced; but that can be disabled by passing NULL
539 fname to yaz_log_init_file.
541 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
543 For SRW (including GFS), accept application/soap+xml as content-type
546 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
547 produces NO stylesheet reference even if a default stylesheet is specified
550 --- 2.1.14 2006/03/14
552 Updated Windows package to include yazd.dll + yazd.lib for the
553 Development component.
555 If the environment variable YAZ_LOG is set, then it is used as a
556 string indicating the default level of logging to use if not
557 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
558 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
559 used as before. So, for example, to omit warnings from YAZ logging,
562 cql_transform() now map structure and other attributes before indexes,
563 so that index-specific structures and other attributes can override
564 defaults. So now a combination of mapping specifications such as:
566 index.dc.date = 1=date-modified 4=5
567 does the right thing.
569 cql_transform() now also respects the "always" mapping specification,
570 which establishes an initial set of attributes to be used for all
571 terms except where overridden by more specific attributes associated
572 with the index, relation or modifier.
574 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
575 which mode to use; one of "post", "get" or "soap" (SRW, default).
577 Fixes for yaz_iconv routines: changed trie-based character set conversions
578 to use only non-negative values for bit fields due to Sun's C compiler not
579 supporting negative values.
581 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
582 sequences where not read correctly. Fix by Rustam Usmanov.
584 Updated win/makefile to use options, settings which makes things
585 compile with VS C 2005.
587 --- 2.1.12 2006/02/01
589 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
591 In ZOOM socket code, use select instead of poll on MacOSX.
593 ZOOM-C now support client-side compilation of CQL into RPN that is
594 sent to the server, enabling CQL to be used against all Z39.50
595 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
596 ZOOM_query object, and submit it using ZOOM_connection_search().
597 The CQL-to-RPN translation uses a configuration file, the name of
598 which must be specified in the Connection's "cqlfile" option.
600 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
601 function, which takes as its start-term parameter a ZOOM_query object
602 (which may have had either CQL or RPN set into it).
605 --- 2.1.10 2005/11/29
607 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
608 GFS to support this as well. Backend handler, bend_srw_update, does the
609 update work. Code contributed by Ko van der Sloot.
611 Allow retrieval of Search Result-1 information in ZOOM by the use of
612 options that are attached to a result set. ZOOM documentation updated
615 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
616 UTF-8 conversion. Patch by Raj Patel.
618 Added option -m to GFS to control formatting of timestamps in log file.
620 Added 'exit' as synonym for 'quit' in yaz-client
622 Added support for specifying SRW resultSetId + resultSetIdleTime in a
623 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
624 for the new members. Patch by Ko van der Sloot.
626 Added support for SRU POST. It is supported for content-type
627 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
629 Do not build the separate Multi-threaded (MT) library libyazthread.la.
630 Instead make the library libyaz.la multi-threaded. Threading as a whole
631 can still be disabled by configure option --disable-threads. Previosly,
632 with older GLIBCs there were problems with MT libs under Apache. This
633 has now been fixed a long time ago.
635 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
638 CQL module modified to be case insensitive for relations/indexes/operations.
640 Fixed bug in CQL transform code: incorrect value relationModifieder
643 Added 'show all' command for yaz-client which retrieves all results
646 Added new yaz-client, xmles, which takes a (private) OID and
647 a document to be sent as an extended service request.
649 Describe new yaz-client commands wait_response and set_auto_wait.
651 Increase TCP/IP listener backlog from 3 (which I am guessing was
652 copied from the SunOS manual entry way back when) so SOMAXCONN, so
653 that the socket will queue as many incoming connections as it's able
654 to handle ongoing connections. In other words, it will never now
655 refuse a connection that it would be able to handle merely because
656 it's not got around to accepting() enough of the pending connections
657 yet. This is the behaviour anyway under Linux, where the listen()
658 argument is ignored; but not under BSD and on systems such as
659 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
660 YAZ-based servers should now be uniform across operating systems in
663 yaz-marcdump uses 64-bit file access on some systems. This is enabled
664 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
665 This allows yaz-marcdump to read large MARC batches (>2 GB).
667 Modified all YAZ source files - except the source which is auto-generated
668 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
671 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
672 corresponding to the existing *_setl() function. These allow option
673 values containing arbitrary valuues.
675 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
676 ZOOM_resultset_sort() in new applications. Its behaviour is identical
677 except that it returns an indicator of whether or not the sort
678 criterion was accepted (0 for OK, -1 for invalid).
682 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
683 MARC output rather than returning "new" buffer.
685 yaz-client warns about unknown init options.
687 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
691 Added support for SRW sort in Generic Frontend Server. Patch
692 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
693 sortKeys - or NULL if none is provided.
695 Fixed bug #307: It was impossible to specify indefinite/no timeout
696 for ZOOM_event. Special timeout value -1 now means indefinite timeout
699 Added support for multiple languages and charsets to be specified in
700 ZOOM. Each charset/language is separated by a blank. If negotiation is
701 in effect in init-response, Option
702 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
703 Code based on patch by Vasiliy Osadchuk.
705 Fixed bug #306: infinite recursion that occurred when calling
706 yaz_log_level_init as the first call (before other log level or
709 Fixed bug in scan handling in front end server: if preferred-Position-In-
710 Response was non-present, a NULL pointer referece was performed.
714 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
715 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
716 now defined for all those error codes. So instead of putting 109 in
717 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
718 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
720 Modified the yaz-marcdump utility to skip garbage bytes between MARC
723 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
725 Program yaz-client now exits and produces an error message if multiple
726 Z39.50 servers are specified on the command line (none or one allowed
729 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
734 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
736 Fixed bug #272: Preserve spacing for CCL terms.
740 Added support for virtual hosts and multiple backend servers for
741 the YAZ frontend server. The configution is XML based and
742 support specificition of CQL to RPN mappings and explain information.
743 See section "Virtual Hosts" in the YAZ manual.
745 Extended OPAC display utility. OPAC display utility renders
746 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
747 to supplement yaz_marc_decode_wrbuf.
749 Fixed a bug in MARC decoder that could caused it to crash for some
750 invalid MARC records. More diagnostics and warnings where added in
751 XML output (warnings, etc are stored in comments).
753 --- 2.0.34 2005/02/08
755 Fixes for UNIX domain sockets. Bug #261.
757 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
759 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
760 Added yaz_marc_subfield_str which defines subfield lead string which is
761 used in YAZ_MARC_LINE format. Default string is blank+$. Added
762 yaz_marc_endline_str which defines end of fields string used in
763 YAZ_MARC_LINE format. Default string is newline.
765 Experimental support for MarcXChange. This format can be produced
766 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
767 http://www.bs.dk/standards/MarcXchange.xsd
769 Added yaz-client commands scansize that sets maximum number of
770 entries to be returned by scan.
772 --- 2.0.32 2005/01/11
774 Added support for SRW scan in yaz-client and Generic Frontend Server.
776 * Added whereInList member to SRW Scan Term.
778 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
780 Fixed NMEM system to return aligned blocks on the smallest boundaries
781 that are suitably aligned for all possible types on the particular
782 architecture YAZ is being built for.
784 --- 2.0.30 2005/01/04
786 Fixed numerious warnings that was issued with newer versions of GCC.
788 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
789 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
792 Make YAZ Generic Frontend Server slightly faster.
794 Enhance (and reduce) logging for Generic Frontend Server.
796 Revert YAZ log system so that it flushes every write operation
797 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
799 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
800 instead of LOG_, due to name clash with syslog(3). LOG_ are still
801 present. New applications should define YAZ_USE_NEW_LOG=1 - this
802 will effectively disable old definitions.
804 --- 2.0.28 2004/11/09
806 Added yaz_log_time_format which specifies log format using
809 Added yaz_log_module_level which returns mask for a module. Value
810 is non-zero mask a if module is enabled; zero if disabled.
812 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
813 in include/yaz/cql.h.
815 Fixed bug #176: Dont throw diagnostics on empty SRU args.
817 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
819 Fixed bug #172: RPM builds does not enable SSL.
821 Doxyfile.in part of dist. Doxyfile generated by configure.
823 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
824 are given and the corresponding component does not exist.
826 Extend CCL documentation in YAZ reference. Describe r=r.
828 --- 2.0.26 2004/10/01
830 Fixed MARC->MARCXML conversion to properly deal with
831 fields, subfields, indicators having non-ASCII characters.
833 Fixed MARC->MARCXML conversion so that ASCII control characters
834 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
837 Added YAZ GFS support for conversion from Z39.50 surrogate
838 diagnostics to SRW surrogate diagnostics.
840 Bug fix: YAZ GFS did not return schema in explainResponse.
842 --- 2.0.25 2004/09/30
844 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
845 now converts recordSchema to elementSetName as well as schema URI.
847 Fixed bug in COMSTACK that prevented HTTP request packages from being
850 --- 2.0.24 2004/09/29
852 Added CCL facility r=r "range" which is similar to r=o "ordered" but
853 does not require white-space before and after the dash in a range, e.g.
854 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
857 Fixed a few AC_TRY_LINK configure tests that did not operate properly
858 due to new GCC removing "redundant" code.
860 Added yaz-client commands scanpos and scanstep that sets preferred
861 position and step-size for scan.
863 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
865 Added CCL utility ccl_qual_buf which parses one or more CCL
866 spec lines in a buffer.
868 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
869 of name and value - ignoring empty lines and comments.
871 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
873 Added odr_get_element_path which returns current element path for an
874 ODR handle. This utility is useful in error handling or user-defined
877 Added ODR_PRINT utility odr_set_stream which is is a more generic
878 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
879 to a write function and pointer to close function. The close function - if
880 non-NULL - will be called during odr_destroy.
882 Fixed bug in CCL parser where truncation char was not removed from
883 right side when truncation=both was in effect.
885 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
888 --- 2.0.23 2004/08/11
890 Fix buffer overrun in CQL parser when dealing with proximity (%).
892 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
893 to UTF-8/UCS conversion is now only based on codetables.xml.
895 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
897 --- 2.0.22 2004/08/06
899 Add support for more "commit changes" in ZOOM (uses Extended Services).
901 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
904 Yet another small fix for configure of SSL.
906 --- 2.0.21 2004/05/14
908 Fix SSL libs for configure when --with-openssl=DIR is given.
910 --- 2.0.20 2004/05/10
912 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
914 SSL comstack now uses yaz.pem certificate file on server side
915 by default. Certificate filename can be configured by calling
916 comstack function cs_set_ssl_certificate_file before cs_bind is used.
918 Fix bug regarding multiple calls to ZOOM_connection_connect.
920 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
922 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
923 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
925 ZOOM now allows inspection of X509 peer certificate for verification.
926 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
928 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
929 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
930 as "modular" but it simplifies things.
932 Added cs_get_peer_certificate to that returns peer X509 PEM.
934 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
935 NULL if SSL is unavailable.
937 Documentation about MARC decoding tools.
939 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
941 --- 2.0.19 2004/03/30
943 Rename CHANGELOG to NEWS to follow GNU style packing.
945 Fix bug with missing initialization of member in init_diagnostics.
946 This bug affects threaded version of GFS server.
948 --- 2.0.18 2004/03/20
950 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
953 Ensure zlib.dll is packed with Windows install.
955 --- 2.0.17 2004/03/17
957 Fix encoding of xsd:string to use text instead of CDATA.
959 Fix endless loop in CQL parser with unbalanced ".
961 Use a more compact way to store MARC-8 conversion tables.
963 --- 2.0.16 2004/03/16 Debian only
965 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
968 Update CQL parser to use new CQL 1.1 modifiers for booleans and
973 --- 2.0.15 2004/03/01
975 Another fix for decoding of XML packed records.
977 --- 2.0.14 2004/02/25
979 Fixes for Chunked encoding. White space not ignored after length spec.
981 Update NS and use default NS for SRW diagnostic elements.
983 --- 2.0.13 2004/02/23
985 Implement ZOOM_resultset_cache_reset which resets record cache.
987 Implement ZOOM_resultset_sort which sorts a result set.
989 Implement chunked HTTP transfer.
991 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
993 --- 2.0.12 2004/02/16
995 Added member 'schema' to bend_explain_rr structure so that backend
996 can specify explain record identifier. Defaults to Zeerex 2.0.
998 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1000 --- 2.0.11 2004/02/16
1002 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1005 Added init command for yaz-client which sends "extra" init request.
1007 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1008 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1010 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1012 Make ZOOM error code for "invalid query".
1014 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1016 --- 2.0.10 2004/02/05
1018 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1021 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1023 Added option -p <file> to make Generic Frontend Server to write PID file.
1025 Added option -D to put Generic Frontend Server in background on its own.
1027 Make ZOOM C recognize option "password". If unset, "pass" is used
1028 (for backwards compatibility).
1030 Fixed a bug in Generic Frontend Server that could make it crash if a
1031 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1034 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1035 Must be issued before open, in order to be in effect.
1037 --- 2.0.9-6 2004/01/12 Debian/Windows
1039 Make the SRU server more picky WRT unknown params, etc.
1041 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1043 New YAZ client command, options, that sets Z39.50 options.
1045 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1046 options from a string of tokens (one token for each option bit).
1048 Update SRW diagnostic code messages.
1050 --- 2.0.9-5 2004/01/07 Debian/Windows
1052 Handle user defined stylesheet for SRW/SRU.
1054 --- 2.0.9-4 2004/01/06 Debian/Windows
1056 Fix bug in decoding of Content-Length.
1058 --- 2.0.9-3 2004/01/06 Debian/Windows
1060 Fix a bug with decoding of XML packed records.
1062 --- 2.0.9-2 2004/01/05 Debian only
1064 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1066 Fix bug in SRW/SRU diagnostics decoding.
1068 --- 2.0.9 2004/01/05
1070 Fixed bug in Generic Frontend Server which could drop records exceeding
1071 preferred message size. Reported and fixed by Irina Dijour.
1073 Fixed calculation of package size for structured records in Generic
1074 Frontend Server. Reported and fixed by Irina Dijour.
1076 Fixed namespace for SRW/SRU diagnostics.
1078 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1080 --- 2.0.8 2003/12/22
1082 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1083 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1086 CQL changes to reflect recent changes to the specification:
1087 * Documentation talks about context sets instead of index sets.
1088 * Documentation talks about indexes instead of qualifiers.
1089 * The CQL-to-PQF transformer's configuration file now uses
1090 "index.set.name = <attributes>" instead of the old form
1091 "qualifier.set.name = <attributes>". (Both forms are still
1092 understood but the latter is deprecated.)
1093 * CQL terms with no explicit index specified are now interpreted as
1094 cql.serverChoice instead of srw.serverChoice (which of course
1095 behaves exactly the same.)
1097 --- 2.0.7 2003/12/16
1099 MARC conversion can now generate ISO2709 output in another
1100 character set. yaz-marcdump uses this facility if you invoke it
1103 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1104 functions from there can be used from C++.
1106 --- 2.0.6 2003/12/04
1108 Frontend server now transfers memory from decoded packages to stream
1111 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1112 references to show up.
1114 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1115 the ZOOM Abstract API. The older names for the same options are still
1116 also supported for the benefit of old applications.
1118 ZOOM-C supports "implementationId" and "implementationVersion" options
1119 to go along with "implementationName". These allow the user code to
1120 specify identification strings to be sent to servers.
1121 Add OID for the new ExtLite attribute set.
1123 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1124 as requested/supplid by Ere Maijala <ere@atp.fi>
1126 For generic frontend server, reverse the order of
1127 "toolkit-supplied / application-supplied" strings sent as implementationId,
1128 Name and Version. Also, remove the spaces around the slash. This brings
1129 the GFS in line with the behaviour of ZOOM-C on the client side.
1131 Add function ZOOM_scanset_display_term.
1133 yaz-client shows scan displayTerm if present.
1135 Utility yaz-iconv is now installed by default along with the man page
1138 Extend configure check for OpenSSL to use pkg-config where available (such
1141 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1142 server to specify uid/gid/mask for socket using the format
1143 unix:[user=uid,][group=gid,][umask=mask,]file=path
1144 If file= is omitted the existing format is assumed, e.g.
1146 in which case the mask is 0666 (rw for everybody).
1148 Major restructure of YAZ source. All source in libyaz is in src directory.
1149 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1150 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1152 Added man page for utility yaz-marcdump (used to be called marcdump).
1153 yaz-marcdump is installed by 'make install'.
1155 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1156 of incoming package failed.
1158 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1160 Change prototype of odr_perror: add const to message string.
1162 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1164 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1165 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1166 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1167 DNS lookup. There should not be any compatibility problems with this
1168 assuming that blocking=1 or 0 is used.
1170 Fix bad reference in UNIX comstack in function cs_addrstr.
1172 Fix for compilation on AIX.
1174 The generic front-end server (server/seshigh.c) now supports returning
1175 Init diagnostics to the client in User-information-field, in
1176 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1179 --- 2.0.4 2003/09/04
1181 Allow any CQL relation (not just all,any,exact,scr).
1183 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1184 that features the same UI.
1186 Implemented command update0 in YAZ client which is equivalent to
1187 update but uses old of Ext Update ASN.1.
1189 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1190 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1191 Previously no OID was used for this info.
1193 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1194 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1195 returns 'malformed search term' otherwise.
1197 SortResponse member resultCount now set to NULL in sort handler of
1200 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1203 Add three new utility functions for translating OIDs between various
1204 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1205 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1206 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1207 char *oid_to_dotstring(const int *oid, char *oidbuf);
1208 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1210 Reverted modifications for ES Update definition for z_IU0Update
1211 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1212 is back to YAZ 2.0.2.
1214 String value attributes for CCL parser.
1216 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1217 which their FirstSearch server returns in Init responses, sometimes
1218 carrying useful diagnostic information when Init fails. This has the
1219 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1220 "z39.50/oclcui.asn", where its definition is somewhat different from
1221 what OCLC document on their web-site, as required to interoperate with
1224 Support for anonymous authentication in yaz-client. Use the command
1227 * Fix the OID of the Index Data-local "admin" Extended Service from
1228 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1229 the 1000, which indicates a locally-defined OID, was a mistake.
1231 --- 2.0.3 2003/06/20
1233 Fix CCL directive @case handling so that it affects string match for
1234 both CCL keywords and qualifiers.
1236 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1237 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1238 Decoder has been updated with ASN.1 changes as listed in
1239 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1240 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1241 z_IUUpdate, remains unchanged.
1243 ZOOM_record_get may now return a record in a specific character set.
1244 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1245 "from" is the character set of record as returned by target. "to" is
1246 the character set to be returned. If omitted, "to" is UTF-8.
1248 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1250 New ODR utility, odr_getelement, which returns name of element for
1251 which encoding/decoding failed.
1253 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1254 in cases where a required element was omitted.
1256 Bug fix: some MARC8 sequences were not converted.
1258 New ZOOM option "step" which specifies number of records to be
1259 retrieved in one chunk. Used in conjunction with "start" and "count".
1261 SRW support for yaz-client. Use scheme http: to use it, e.g.
1264 yaz-client no longer does (un)intelligent character set conversions
1265 by default. Can be enabled with charset and marc_charset commands.
1267 xmalloc trace fix for 64-bit systems such as DEC alpha.
1269 Solaris 2.6 compile fix.
1271 New function, cql_strerror() translates SRW error codes, as returned
1272 by cql_transform_error(), into human-readable English strings. Used
1273 in yaz-client diagnostics when appropriate.
1275 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1276 converts it into a type-1 query which is sent to the server. This
1277 makes CQL available for use with all Z-servers, as opposed to the tiny
1278 minority that can handle CQL queries themselves.
1280 --- 2.0.2 2003/04/28
1282 New Debian package layout similar to the Redhat Package layout.
1284 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1285 and search result respectively.
1287 --- 2.0.1 2003/04/25
1289 Redhat package is now several packages: libyaz (runtime libraries),
1290 libyaz-devel (development and documentation, and yaz (utility programs).
1291 Package spec file by Morten Bøgeskov.
1293 New member 'schema' in struct bend_fetch_rr which the name of requested
1294 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1295 handler MAY set this to reflect the schema of the returned record.
1297 New member 'display_term' in struct scan_entry. GFS now sets member entries
1298 and allocates scan entries to be filled by user scan handler. In previous
1299 version, entries member was allocated by the scan handler. That still works,
1300 but the GFS will ignore member display_term - assuming it was NOT set by
1301 the handler. The fact that the GFS now allocates the entries both allows
1302 for new members and makes a scan handler easier to write.
1304 Fix CQL lex buffer overflow.
1306 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1307 SRU default recordPacking is string.
1309 SRU protocol support for frontend server.
1311 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1313 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1315 Added scan for the ZOOM shell (zoomsh).
1319 * String Identifers for Schemas (Amendment 5).
1320 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1321 Old definition for schema
1322 Odr_oid *schema; /* OPT */
1327 Z_InternationalString *uri;
1328 #define Z_Schema_oid 1
1329 #define Z_Schema_uri 2
1332 * resultCount parameter to Sort Response (Amendment 1).
1333 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1335 Support for SRW 1.0 over HTTP. This is an optional feature and
1336 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1339 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1340 on the same port. SRW SearchRetrieveRequests are mapped
1341 to bend_init,bend_search,bend_fetch,bend_close.
1343 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1345 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1346 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1348 ZOOM connections are SRW based if schem http is used for hostname
1349 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1350 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1352 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1353 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1354 distance=n, order=true/false, relation=le, prox unit=word. If
1355 n is omitted, distance 1 is used.
1357 Fixed problem with C compiler include path in wrong order.
1359 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1360 on Solaris. Patch from Ko van der Sloot.
1362 New MARC decode API. All new functions operate on a yaz_marc_t
1363 handle. The most important new functions are: yaz_marc_create,
1364 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1365 decode and destroy respectively. Decoder can produce formats
1366 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1367 include/yaz/marcdisp.h.
1369 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1370 to UTF-8, UCS-32, wchar_t or Latin-1.
1372 * Prototypes for yaz_iconv_-functions moved to separate header
1373 include/yaz/yaz-iconv.h.
1375 Make a few private functions 'static' in unix.c. This prevents
1376 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1378 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1379 are set when Init Response is received.
1381 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1382 but returns diagnostic set as well.
1384 New function yaz_strerror which is a portable wrapper for
1385 strerror/strerror_r/GetLastMessage.
1387 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1388 is returned for MARC. If type is "oai", then OAI MARC is returned.
1390 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1393 --- 1.9.2 2002/11/26
1395 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1397 Fix bad race conditions on SIGTERM and terminate gracefully in
1400 Move retrieval (data1) module to Zebra since nobody seems to be
1403 Add GRS-1 render for ZOOM using same format as yaz-client.
1405 --- 1.9.1 2002/10/05
1407 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1409 Fix broken ESpec handling in data1 module.
1411 SGML reader parses comments and makes them part of the data1 tree.
1413 Added several type casts so that YAZ compiles as C++ code.
1415 ZOOM didn't handle PDU encoding failures properly.
1417 Added more Bib-1 diagnostics (approved extensions).
1419 GNU configure: better check for iconv.
1421 More portable use of accept, getpeername. Check for socklen_t. Use
1422 int/size_t if socklen_t is not defined.
1426 PQF parser rejects bad queries - including those with extra
1427 characters in them. PQF parser used to silently ignore that.
1428 Cleaner API for PQF added, which allows you to get detailed
1429 error information for bad queries (see yaz/pquery.h).
1431 Fixed bug in ZOOM_record_get for type "database".
1433 Implemented mini iconv library supporting conversions between
1434 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1436 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1438 --- 1.8.9 2002/08/20
1440 Fixed ZOOM C record cache so that preferredRecordSyntax and
1441 elementSetName is used to check for already fetched records.
1443 --- 1.8.8 2002/08/02
1445 Added three members in bend_initrequest structure to facilitate
1446 character set negotiation.
1448 Fixed a bug in frontend server that could cause indefinite
1449 loops under rare conditions.
1451 Revised character set utilities (charneg.h) so that encoding
1452 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1454 For PQF, directive @term <type> sets term type for Scan/Search.
1455 Here <type> is general, string, numeric, null. The term type
1456 is inherited - just like @attr.
1458 New call odr_set_charset that sets character set conversion for
1459 international-strings on a ODR stream. Prototype is:
1460 int odr_set_charset(ODR o, const char *to, const char *from);
1461 The InternationalString is still represented as C string in YAZ
1462 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1463 won't). On the protocol level, you can use any encoding.
1465 Support for UNIX sockets in ZOOM.
1467 Solaris recv sometimes returns errno == ENOENT. It is treated as
1468 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1470 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1471 both client and server. Code by Morten Bøgeskov.
1473 --- 1.8.7 2002/05/22
1475 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1476 that they can be used directly from Visual Basic. You must recompile
1477 your windows APP if you're using ZOOM.
1479 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1480 Commands "lang" and "charset" sets language and character set respectively.
1481 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1482 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1484 Attributes from multiple CCL fields may be OR'ed rather than merged
1485 using directive "@field or". Fields are still merged by default -
1486 equivalent to "@field merge".
1488 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1491 Fixed bug in zget for parameter ExtendedServicesResponse.
1495 --- 1.8.6 2002/03/25
1497 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1499 Client displays USR.1:SearchResult-1 (hits per term).
1501 Additional Search Info for search in Generic Frontend Server.
1503 Fixed CCL parsing of "field=s".
1505 WIN32 installer - using the excellent NSIS software from nullsoft.
1507 Fixed CCL parsing of "field = - <number>".
1509 Added function yaz_marc_decode that decodes MARC for line mode
1510 display or XML (similar to that used by JZKit).
1512 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1513 Z39.50. But ISO/ILL was, however.
1515 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1516 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1518 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1519 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1521 --- 1.8.5 2002/02/03
1523 New YAZ client features: Command completion and new commands:
1524 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1525 Code provided by Jacob Poulsen.
1527 New call oid_trav, that visits all registered OIDs via callback.
1529 Function ZOOM_record_get now returns const char pointer rather than
1530 void pointer. It saves a lot of type casts.
1532 For YAZ client, command "auth" now allows you to set authentication
1533 in IdPass style. It is enabled when three tokens are given - order
1534 is user, group and password.
1536 Fix memory leaks in MARC record handling for ZOOM.
1538 New option for YAZ client, -k <kilobytes> that sets
1539 maximum record size. Similar to -k option for generic frontend
1540 server and yaz-ztest.
1542 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1544 Prefix query parser reports "fail" when bad attribute set is given.
1546 Fix in MARC decoder. Proximity logging. Fix for attribute set
1547 in scan handler for server. Patches by Shigeru Ishida.
1549 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1552 Configure option --with-openssl=<dir> now works when a directory is
1553 specified. Patch provided by Morten Bøgeskov.
1555 New option for YAZ client, -u <auth>, that sets authentication.
1557 ZOOM fix: error information was sometimes "missing", since error
1558 was cleared/reset too when it shouldn't.
1560 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1562 --- 1.8.4 2002/01/04
1564 Scan for ZOOM API. New object ZOOM_scanset. New functions
1565 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1566 ZOOM_scanset_destroy.
1568 New ZOOM function, ZOOM_connection_last_event, that returns type
1569 of last event (such as "receive data", "send data", "apdu received",
1572 New ZOOM option, schema, that specifies schema for retrieval.
1574 New CCL feature. Qualifiers can be aliases for one or more
1575 other qualifiers (if more than one is given, OR is used).
1577 ZOOM uses named result sets if target supports it.
1579 Two new YAZ client commands: . (dot, which sources a script of YAZ
1580 client commands), and ! (to execute shell command.). Implemented
1583 Working on Debian packages.
1585 --- 1.8.3 2001/11/19
1587 YAZ client enables named result sets only if target supports it.
1589 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1591 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1592 with key="host" to get same result.
1594 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1595 Function Z3950_resultset_record(s) returns references to records
1596 "owned" by resultset. To become owner use Z3950_record_clone.
1598 Function z_ext_record handles Extended Services. Thanks to
1601 --- 1.8.2 2001/11/12
1603 CCL Parser fix: ignore token comma when dealing with and-lists.
1605 Documentation updates for COMSTACK.
1607 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1608 Changed prototype Z3950_records. For some functions, int parameters
1609 were changed to size_t.
1611 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1614 New MARC decode/display function, marc_display_exl, which properly rejects
1615 non-ISO2709 records. YAZ client uses it.
1617 --- 1.8.1 2001/10/29
1619 Fix bug: local attribute set wasn't set correctly in PQF strings.
1623 * Old Z39.50 codecs no longer supported.
1625 Added ZOOM C binding. See http://zoom.z3950.org/
1627 Renamed states for COMSTACKs to avoid confusion with events.
1629 Implemented cs_look and proper cs_rcvconnect.
1631 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1633 Configure detects POSIX threads on OpenBSD.
1635 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1636 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1638 When error is returned from present handler, non-surrogate diagnostic
1639 is returned in present response (and fetch handler is no longer called).
1641 * Minor adjustments to pquery parser (PQF). Token characters may be
1642 escaped by using backslash (C-style).
1644 PQF parser allows string attribute values to be specified. For @attr,
1645 non-numeric characters after the equal-sign are treated as strings
1646 (e.g. @attr 9=title).
1648 CCL trunction character may be defined (@truncation in file)
1650 * function zget_ExtendedServicesRequest sets waitAction to
1651 waitIfPossible (was wait).
1653 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1656 CCL operator names may be set in field definition files (CCL_bibset).
1657 See ccl/bib1 for an example.
1659 Fixes in ASN.1 compiler for C++ compatibility.
1661 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1662 and "op_or" to avoid conflict with C++.
1664 Fixed problem with GNU readline detection on Redhat 7.0.
1666 Added step-size for Scan backend handler.
1668 Fixed bug that made the frontend server crash when no attribute
1669 set was specified for scan.
1671 Front-end server automatically switches to original working directory
1672 when installed as an NT service. Previously -w had to be specified to
1675 Added extended attributes for retrieval module (data1), so that data1
1676 records carry d1_readXML/SGML attributes. d1_read also supports
1677 null-data rules ( <tag/>)
1679 On UNIX when POSIX threads are available, a separate library libyazthread
1680 is created. Programmers should link with that library and the yaz library
1681 when using threads. The reason for the split was that some applications
1682 on Linux, such as Apache, doesn't work well when using shared objects that
1685 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1686 (or any frontend server) in SSL mode by specifying ssl: followed by
1687 address. Only tested on UNIX.
1689 Added feature for CCL module. Virtual structure s=al or s=ol generates
1690 and-list and or-list respectively instead of phrase search.
1694 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1695 log_mask_str. This was done to avoid name conflicts with other libraries
1696 (such as other PHP extensions).
1698 Added raw OID member for preferred record syntax (request_format_raw)
1699 and returned record syntax (output_format_raw) for backend fetch method.
1701 Config file yaz-config now accepts options so that it returns specific
1702 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1704 Shared library support for UNIX using GNU libtool.
1706 * Modified backend interface. Request/Response struct's replaced by
1707 one read/write C struct. For example bend_fetchrequest and
1708 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1709 Every handler - even search has to be registered in bend_init
1710 handler. This means that the YAZ library no longer refers to
1711 external functions and it makes it possible to make the whole
1712 thing a single DLL/SO.
1714 Added Segment handler for backend server.
1716 Added Zmbol/Zebra administrative functions to YAZ client.
1718 Threaded frontend server on UNIX (when POSIX Threads are available).
1719 Starting the server with option -T enables multi-threading.
1723 Added configure option --enable-comp/disable-comp to control use
1724 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1725 located in sub directory asn.
1727 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1728 in ${exec_prefix}/bin along with the other programs yaz-client and
1731 GNU automake used to maintain makefiles.
1733 Added several OID's.
1735 Changed retrieval module so that we can load records with no abstract
1736 syntax defined. Tagpaths in these records are fully composed of string
1739 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1743 On UNIX, the generated makefile now supports a proper 'make install'.
1744 The prefix can be set via GNU configure to set the install location
1745 (default is /usr/local).
1747 * YAZ programs client and ztest were renamed to yaz-client and
1748 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1749 locations, such as /usr/bin,/usr/local/bin,etc.
1751 * YAZ Header files were moved from include to include/yaz. YAZ Header
1752 files are referred to as include <yaz/log.h> rather than <log.h>.
1753 The YAZ include path (-I ..) is therefore the same as before. Programmers
1754 should update their #include statements or use -Ipath/include/yaz
1755 instead. The main motivation for doing this change is that YAZ header files
1756 can be installed in "standard" locations /usr/include,/usr/local/include
1757 without introducing conflicts, since ALL YAZ header files are stored
1758 in subdirectory yaz (under /usr/include for example).
1760 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1761 rather than project/workspace files. We switched because project files
1762 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1765 Changed name of logging function, logf, to yaz_log, to prevent name
1766 clash with some math-log functions. The YAZ header log.h defines logf
1767 to yaz_log (#define) so there should be no incompatibilities by this
1770 Added bend_start/bend_stop handlers for server. These handler are
1771 called on start/stop of server. For windows they are called whenever
1772 a service is started/stopped.
1774 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1775 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1776 in util/yc.tcl. The auto-generated C code structures are, in a few
1777 cases, incompatible with the old decoders. There are differences in the
1778 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1779 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1780 The preprocessor variable ASN_COMPILED is defined when the compiled
1781 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1782 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1783 wish to use the old encoders/decoders you can specify --disable-yc
1786 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1787 version so that it supports both new - and old version of DB Update
1789 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1790 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1791 change. The name parameter can be set to 0 in which no name is specified
1792 for the construction. The macros odr_implicit and odr_explicit sets name
1793 parameter to zero for the construction involved. New macros
1794 odr_implicit_tag and odr_explicit_tag are similar to the others,
1795 except that a name parameter is added. For programmers' that don't use
1796 ODR they probably only need to change the call to z_APDU and z_External.
1798 Added access control facility by interfacing the TCP wrapper library.
1799 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1800 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1801 name of the daemon and enables the access control as specified in
1802 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1804 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1805 den Dool <H.M.vdnDool@kub.nl>.
1807 Added reference ID parameter to most functions in server API - refer
1808 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1810 Changed name of ccl library to libccl.a (was ccl.a).
1812 Fixed bug in decoder for Explain (Category TargetInfo).
1814 Added support for GNU readline in client. Thanks to Jacob Poulsen
1815 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1817 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1818 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1819 IMPLEMENTATION! This change was made to the development version before
1820 the ZIG decided to retract the amendment. If any users MUST be
1821 compatible with the original Update definition, PLEASE CONTACT US, and
1822 we will include a separate definition corresponding to the old Update
1823 ES. Note that because of the change to the ASN.1 of the
1824 TaskPackageRecordStructure we cannot define a single structure that
1825 will support both versions.
1827 * Added const modifier to buffer parameter for some ODR/BER encoding
1828 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1829 completeWAIS, odr_dumpBER.
1831 Fixed bug in client.c which caused a crash when a scanResponse didn't
1832 contain positionOfTerm.
1834 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1835 * will cause an error in a client if a non-YAZ target sends both a
1836 * list of Scan entries and non-surrogate diagnostics.
1838 Retrieval module enhancements. Tag sets may be typed in the reference
1839 to it. From the .abs-file the "tagset" directive takes a third optional
1840 integer type for the tag set referenced. From a .tag-file the "include"
1841 directive takes a third optional type as well. The old "type" directive
1842 in the tag set itself is still recognized but acts as the default type
1845 Backend interface change. Individual Scan terms returned from bend_scan
1846 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1847 in include/backend.h.
1849 Retrieval module enhancements. Multiple tag sets and attribute sets may
1850 be specified in abstract syntax specs. Revised the error/warning for
1851 logging messages reported by the retrieval module when reading the
1854 Object Identifier system (oid_..) changed. The API is backwards
1855 compatible but the oid-routines now allocates new OID's when needed.
1856 Raw OID's may be specified in oid_getvalbyname.
1858 YAZ now uses GNU configure to generate Makefile(s).
1860 * Minor changes in some of the member names of DeleteResultSetRequest and
1861 DeleteResultSetResponse. See include/proto.h.
1863 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1864 and added member 'languages' in TargetInfo (which was missing).
1866 Changed the way attribute sets are handled in the retrieval
1867 module. These are now cached, just like the abstract syntaxes
1870 Changed YAZ so that it links with compiled ASN.1.
1872 Added Explain-schema definitions and mapping routines. The following
1873 Explain categories have been implemented: AttributeDetails,
1874 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1876 Fixed minor bug in Windows version of Server Library.
1878 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1880 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1882 Added EXTERNAL: UNIverse Resource Report (non-standard).
1884 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1885 ENUMERATED and SET OF.
1887 * Added 'const' to some of the char pointer arguments for the
1888 functions, data1_read_node, data1_getelementbytagname,
1889 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1892 Fixed bug in data1_insert_taggeddata - the last_child member of
1893 parent wasn't initialised.
1895 * Changed data1_read_record and data1_read_node so that the supplied
1896 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1897 doesn't refer to any parts of the "SGML"-buffer.
1899 Fixed bug in server library (Windows version of statserv_remove).
1901 * Changed code so that it compiles as C++. The type definition
1902 of Odr_fun which is a member of Odr_arm was changed. The result is,
1903 that an explicit typecast is needed for the fun pointer when
1904 using Odr_arm - as in:
1905 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1907 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1909 Implemented the new structured date and time definition as approved
1910 by the ZIG. Added schemaId element to the specificTag in Espec-1
1911 (also approved at the last ZIG). Thanks to RVDM.
1913 Added some Object identifiers (RVDM).
1915 Changed the Update Extended Service (RVDM).
1917 Added command "refid" to client which specifies referenceId for
1918 the following requests.
1920 Implemented extended service handling for server. See ztest.c
1921 for an example as well as backend.h. New handlers are registerd
1922 in the Init handler.
1924 * Changed interface for sort in server.
1926 Added new members to statserv_options_block. It allows a server
1927 to read options from another source than just the command line. Thanks
1928 to Charles Woodfield.
1930 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1931 renamed to zboolean. Some C++ compilers complained about the name.
1933 Minor changes to gils.abs. Added index 's' (sort) on title
1934 and date/time-last-modified.
1936 --- 1.4pl2 1998/1/30
1938 Fixed bug in server library regarding inetd mode (-i). This bug
1939 was introduced by release 1.4.
1941 --- 1.4pl1 1998/1/29
1943 Added sort facility in client and backend server interface.
1945 Fixed problem with dependencies in Makefile(s).
1947 Fixed bugs for encoders/decoders of extended services and
1950 Implemented sub-tree feature for schemas. Sub-trees are
1951 referenced in *.abs-files. See explain.abs for an example
1952 of the use of this feature.
1954 Modified bib1.att; local attributes for ANY didn't include
1955 ANY itself (only affects use of the retrieval module).
1957 Fixed bug in plain SGML reader in function data1_read_node:
1958 tags with prefix "var" was incorrectly interpreted as variants.
1960 Added feature "sub-schemas" to enable references to - and definitions
1961 of - group of elements.
1963 * Removed member parent from type data1_element (in data1.h).
1965 Implemented function odr_nullval() that returns the value of
1968 * Removed member num_children from data1_node (in data1.h).
1970 Made NT service interface part of the server library. The
1971 function statserv_main uses the NT service when required and
1972 calls the statserv_start / statserv_close routines.
1974 Routine zget_SearchRequest and zget_PresentRequest fills
1975 resultSetName/Id member with "default" instead of "Default".
1977 Fixed memory leak in server. Request queue member wasn't freed.
1979 Fixed nmem_exit so that memory is freed.
1983 Revised the CCL parser utility to be thread safe.
1985 Added function, oid_ent_to_oid, to replace the function
1986 oid_getoidbyent, which is not thread safe.
1988 * Added nmem_init and nmem_exit to initialize and release
1989 NMEM resources. Function nmem_init should be called once in the
1990 initial thread before NMEM/ODR is used. statserv.c and client.c
1991 have been changed accordingly. The change was necessary to make
1992 NMEM thread safe. The NMEM memory pool is shared amongst threads
1993 in a process. Unix-based applications will still work fine without
1996 Added NT Services interface for the the Z39.50 (statserv) Server.
1997 Refer to the ztest.c source on the usage.
1999 Windows 95/NT port using MSVC5.0. Project files are included in the
2002 * Defined new 'global' handle for the retrieval (data1) system. The
2003 new handled, data1_handle, describes the state of the data1 system.
2004 This handle is passed as first argument to virtually all
2005 data1 related routines. The functions data1_create and data1_destroy
2006 creates and destroys a data1 handle respectively.
2008 Added ODR encode stream member to all backend request structures
2009 init, search, scan etc. This stream should be used to allocate all
2010 memory used for the response when thread safe operation is needed.
2012 Changed the comstack utility, cs_addstr, to be thread safe. The
2013 returned hostname string returned by the function is now part the
2016 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2017 function. The cs_straddr takes a COMSTACK handle as argument, so this
2018 function must be used after cs_create and before bind/connect.
2019 This function is thread safe.
2021 Moved test server to 'ztest' directory - generic server code still
2022 in 'server' directory.
2024 Made prefix query (pquery.c) utility thread safe.
2026 Added new function modifier YAZ_EXPORT to 'export' public DLL
2027 functions when using windows (see include/yconfig.h).
2029 Added definitions to the OID database (util/oid.c) (RVDM).
2031 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2033 Added call to ccl_rpn_delete in client program.
2035 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2036 release of RPN structure.
2038 Added support for C++, headers uses extern "C" for public definitions.
2039 With input from RVDM.
2041 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2042 Thanks to Ronald van der Meer (RVDM).
2044 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2046 Added support for private extensions to the OID database
2047 (oid_setprivateoids()). Thanks to RVDM.
2049 Added optional, physical ANY (key replication)
2051 Fixed null-reference problem in GRS-1 output filter.
2053 Proximity operator added to Prefix Query Format (PQF).
2055 In test client command "base" accepts multiple databases.
2057 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2061 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2063 Smallish bug-fixes in the new encoders/decoders (explain).
2065 Bug fixed in DeleteRequest.
2067 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2069 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2071 Added SOIF syntax (using private OID for now) to retrieval module and client.
2073 Added Update extended service.
2075 Added SearchResult-1 additional info structure.
2077 Added optional CCL (ISO8777) interpreter as separate module. Available
2080 --- 1.2 1996/6/10 (1st anniversary release)
2082 Added Summary record syntax. Lightly tested.
2084 Added OPAC record syntax. Untested.
2086 Added ResourceReport service encoders/decoders. Untested.
2088 Fixed bug in z_Unit - wrong tagging on unitSystem.
2090 Fixed bug in the DiagRecs decoder.
2092 Added options for max PDU size and session timeout to frontend-server.
2094 Added documentation of query-language parsers and other supporting utilities.
2096 [frontend-server] Added Attribute set to the bend_scanrequest API.
2098 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2099 surrogate diagnostics were generated.
2101 [retrieval] Allow multiple local values for attribute.
2103 [retrieval] Allow multiple attributes per element in .abs files. index type.
2105 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2107 --- 1.1pl2 1996/4/10
2109 Minor changes, mostly specific to Zebra's requirements (retrieval)
2113 Repaired bug in frontend server when running multiple listening
2114 endpoints in dynamic mode.
2116 z_External() now won't break if a known, ASN.1 value comes encapsulated
2117 in an octet-string. The value will pass through unmodified in an Odr_oct.
2119 Added a bit of code to the demo client to decode & display
2120 ASN.1-structured records represented in the octet-aligned branch of
2121 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2123 Added z_ext_getentbyref() to the ASN module. Doc updated.
2125 * Completed the SCAN definition in the ASN module. This may break SCAN
2126 code based on older YAZ-versions at compile-time. The fix is easy -
2129 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2130 under the SCAN definition. Remember to initialize this, server-people.
2132 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2133 that this does not extend to ODR and ASN.
2135 Comstack allows insertion of established socket (primarily for
2136 inetd-operation of servers). Doc updated.
2138 Front-end server can now start from the inetd in TCP mode. Doc
2141 --- 1.0pl4 1996/1/24
2145 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2146 the rank and record number.
2148 Adjustments to the frontend server.
2150 Fixed diagnostic BER dumper. It ignored the file argument.
2154 Various changes to retrieval module.
2156 Changed the union discriminators of the protocol files from enums to
2157 ints paired with #defines.
2159 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2162 *Changed operator in the RPN structure to 'roperator', again to avoid a
2165 Fixed problems in Explain decoders/encoders.
2167 --- 1.0pl2 1995/12/6
2169 Memory bug in log module fixed.
2171 --- 1.0pl1 1995/12/5
2173 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2175 Bug in Explain DatabaseInfo module fixed.
2177 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2181 The shift to v1.0 signals that we now consider the *core* functionality
2182 of YAZ reasonably stable (the core being more or less equivalent to
2183 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2184 tested (Explain not at all - though that will happen soonish).
2186 Minor changes to code to support Windows port.
2188 Various minor changes after we're getting to use GRS-1 & co. more.
2190 Added Espec-1 format.
2192 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2193 of the protocol and it cannot be selected when encoding (maps into 'string'
2194 when decoding). Needed to talk to some servers.
2196 Demo client can request simple element set names.
2198 Added Diagnostic Format encoders/decoders.
2200 Added simple Close handling to frontend server (no hooks for resource
2201 reporting yet), and demonstration client.
2203 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2205 --- 1.0b3 1995/08/24
2207 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2208 handled incorrectly when records were requested in the searchResponse. This
2209 will only affect you if you use the frontend-server.
2211 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2212 Test-client will ask for and print GRS1. Ztest will return dummy records
2215 Added Explain encoders/decoders to the service-level API. Untested.
2217 Added Extended Services: Item Order encoders and decoders to the Service-
2218 level API. Untested. We could use a recent copy of the pertinent bits
2219 of the ILL protocol to add those bits.
2221 Added diagnostic format 1 encoders/decoders to the service-level API.
2224 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2225 odr_cons.c, which causes a more correct output.
2227 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2228 was always set to 0 when no records were requested in the searchRequest.
2230 * Added better external-handling. This shouldn't harm old code that
2231 *encodes* externals. It can break code that looks for a
2232 'single-ASN1-type' representation, since those types that are known
2233 are now decoded immediately. Look at the SUTRS sample code in
2234 seshigh.c and client.c. Documentation updated.
2236 Handling of structured records in bend_fetchresponse. Length -1 marks
2237 structured record, type is deduced from format field.
2239 --- 1.0b2 1995/06/27
2240 Fairly quick maintenance release to add SUTRS support.
2242 Fixed handling of SUTRS records in the demonstration client.
2244 * Added format field to the bend_fetchrequest and bend_fetchresponce
2245 structures of the backend API (frontend server). When the record is
2246 returned, the value of the format field is mapped to an OID. The
2247 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2248 of the record. The special value VAL_NONE in the bend_request means
2249 that no specific format was requested by the client. Documentation
2250 updated accordingly. Test server (ztest) will return a fixed dummy
2251 SUTRS record if your client requests SUTRS.
2253 Documentation updated accordingly.
2255 You can now set external libraries and RANLIB support in the top-level
2259 First public release.
