1 Implemented function yaz_marc_read_line which parses MARC line format
2 records. There is a wealth of formats out there. So far, this function
3 reads line records produced by yaz_marc_write_line.
5 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
6 more generic and easier to remember(!) options: -i format and -o format
7 which specifies input format and output format respectively - where
8 format is one of "marc", "marcxml", "line", "marcxchange".
10 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
11 does not print anything except warnings for records.
13 For yaz-marcdump, added support for MARC split into files (-s) with a given
16 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
17 spec, at http://www.loc.gov/standards/sru/record-update/
18 This has changed the binary layout of the following structs:
19 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
20 bend_update_rr . Patch by Ko van der Sloot.
22 Added GFS utility function bend_assoc_is_alive which returns 1 if
23 association is still alive (client is connected); 0 otherwise (client
24 closed connection). This allows busy servers to stop working for
27 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
28 been a separate piece of software. This version of ziffy has been modified
29 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
31 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
33 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
34 Client code may now interrogate options such as "init_opt_sort" to
35 find out whether the server claims to support various options.
39 Added utilities yaz_{set,get}_esn to set/get element set name from
42 Removed the build of libyazthread.la. The libyaz.so is the threaded version
43 of YAZ and has been so since YAZ 2.1.10.
45 Implemented ZOOM_record_error which returns error information for
46 record (surrogate diagnostic).
50 Updates for SRU Update by Ko van der Sloot:
51 1. Changed name from "operation" to "action"
52 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
53 versions in the code, marked as 'backward compatible'.
54 3. Added diagnostics for SRU Update.
56 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
58 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
60 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
62 For GFS, fixed problem with SRU diagnostic 'First record position out of
63 range' being issued for 0 hits.
65 zoomtst10 part of Windows Build.
69 Implemented yaz_filepath_comp which splits a path into file path
70 components (required by Zebra 2.0.3+).
72 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
73 BSD inspired license until now so this should not have any real impact on
74 anybody. See http://www.opensource.org/licenses/bsd-license.php
76 Fixed bug #687: Missing log lines.
78 Fixed bug #678: CQL to PQF translation does not preserve double-quote
81 Fixed bug #689: SRU diagnostics to be added.
83 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
84 whether a connection is idle (no more work do do).
88 Change type of optval from long to int for invocation of setsockopt with
89 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
91 Added support for specifying the max log file size for the Generic
92 Frontend Server. The size is given with option -r.
96 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
100 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
103 Fixed bug in Generic Frontend Server that could cause a server to stop
104 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
106 For the generic frontend server, the maximum record size is used as maximum
107 size of incoming packages (SRU + Z39.50). The value until was previously
108 only used in Z39.50 Init negotiation and, later, in a session controlled
109 sizes of records returned. This is controlled using -k option. It can be
110 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
112 --- 2.1.28 2006/09/04
114 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
117 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
119 New option for yaz-marcdump -lpos=value which allows setting a portion
120 of MARC header to a certain value.
122 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
124 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
125 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
127 --- 2.1.26 2006/08/15
129 Fixed problem with SRU mode type (soap, get, post) for yaz-client
132 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
134 --- 2.1.24 2006/08/08
136 Fixed MARC ISO2709 encoding routines to deal with character set
139 Minor changes to GFS logging. Database included in search request log
142 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
143 cached/multiple records.
145 Shared libraries are built by default on Unix+configure.
147 Changed cql2pqf transformation to use a different evaluation order. The
148 new order is: always, relation, structure, position, truncation, index
149 and relationModifier. Old order was: always, relation, relationModifier,
150 structure, index, position, truncation. Note that the the latter ones
151 override former ones for identical attributes.. The new scheme means that
152 it is possible to override any existing attribute with a relationModifier.
153 And also that it is possible to override everything for the index rule
154 (except the ones listed in relationModifier). No order is perfect but this
155 one, we believe, covers more real cases.. The "always" should have been
156 called "default", since the attributes there can be overridden with all
159 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
160 compilation phase, but also for yaz-config --cflags output. This allows
161 us to have public headers with Libxml2 stuff in them . It should also,
162 eventually, make Libxml2 checks redundant in packages using YAZ, such
165 --- 2.1.22 2006/06/15
167 Changed SRU update structure bend_update_rr so that SRU diagnostics are
168 stored in uri, message and details.. Previously diagnostics were stored
169 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
170 compatibility.. but he's probably the only one affected, so.
172 Added support for CCL, compiled on the client side, in ZOOM-C. This
173 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
174 input; the resulting query objects can be used for for searching with
175 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
177 YAZ' configure searches for OpenSSL by default.
179 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
180 SL_CTX_use_certificate_file. See
181 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
182 for more info. Thanks to Ko van der Sloot.
184 --- 2.1.20 2006/06/02
186 Bug #600: SRU GET, POST support for yaz-client. Introduced
187 command 'sru' which selects method SOAP/GET/POST.
189 Allow missingValueAction to be specified for the sortspec string -
190 function yaz_sort_spec. By default, the missing value action is null.
191 Use ! to specify "abort". Use = followed by stringvalue to specify default
194 Ensured that Present-handler (if defined) is called in GFS before any call to
195 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
196 searchRetrieve requests.
198 Documentation for YAZ is now based on the Docbook XML/XSLT using
199 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
200 is no longer depending on jade/openjade or docbook-to-man scripts.
201 PDF is no longer part of the distribution - but can optionally be
202 made using DSSSL/jadetex or FOP.
204 Added retrieval handling support in Generic Frontend Server to support
205 conversion between MARC/XML as well as XSLTtransforms. See
206 etc/yazgfs.xml for an example.
208 Added Authentication support to Generic Frontend Server in SRU
209 mode. Authentication using HTTP Basic is supported, as is the use
210 of 'x-username' and 'x-password' parameters in the request itself.
212 Added support for a new character set MARC8s identical to MARC8 except
213 that it converts combined characters to single Unicode characters in the
214 Latin-1 range (when possible).
216 --- 2.1.18 2006/04/24
218 ASN.1 compiler 0.4: generates brief Doxygen file header for
219 generated .h/.c files.
221 Utility yaz_iconv now supports conversion to MARC-8.
223 New facilities for the MARC module. The reading - and writing of
224 content are separate methods for the yaz_marc_t handle. The following
225 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
226 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
227 format). Write functions have prefix yaz_marc_write_.. The existing
228 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
229 available. Removed support for OAI-MARC and simplexml (not the
230 simplexml from PHP5).
232 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
233 to be returned for this connection.
235 --- 2.1.16 2006/03/31
237 Allow multiple languages and charsets to be specified with
238 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
239 negcharset iso-8859-1,utf-8
241 Translation of proximity nodes from CQL into PQF now works.
243 Moved to automake 1.8, 1.9.
245 Added function yaz_log_set_handler which allows a log handler to be
246 installed. This handler will be called for all log messages. Output
247 to file is also produced; but that can be disabled by passing NULL
248 fname to yaz_log_init_file.
250 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
252 For SRW (including GFS), accept application/soap+xml as content-type
255 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
256 produces NO stylesheet reference even if a default stylesheet is specified
259 --- 2.1.14 2006/03/14
261 Updated Windows package to include yazd.dll + yazd.lib for the
262 Development component.
264 If the environment variable YAZ_LOG is set, then it is used as a
265 string indicating the default level of logging to use if not
266 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
267 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
268 used as before. So, for example, to omit warnings from YAZ logging,
271 cql_transform() now map structure and other attributes before indexes,
272 so that index-specific structures and other attributes can override
273 defaults. So now a combination of mapping specifications such as:
275 index.dc.date = 1=date-modified 4=5
276 does the right thing.
278 cql_transform() now also respects the "always" mapping specification,
279 which establishes an initial set of attributes to be used for all
280 terms except where overridden by more specific attributes associated
281 with the index, relation or modifier.
283 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
284 which mode to use; one of "post", "get" or "soap" (SRW, default).
286 Fixes for yaz_iconv routines: changed trie-based character set conversions
287 to use only non-negative values for bit fields due to Sun's C compiler not
288 supporting negative values.
290 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
291 sequences where not read correctly. Fix by Rustam Usmanov.
293 Updated win/makefile to use options, settings which makes things
294 compile with VS C 2005.
296 --- 2.1.12 2006/02/01
298 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
300 In ZOOM socket code, use select instead of poll on MacOSX.
302 ZOOM-C now support client-side compilation of CQL into RPN that is
303 sent to the server, enabling CQL to be used against all Z39.50
304 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
305 ZOOM_query object, and submit it using ZOOM_connection_search().
306 The CQL-to-RPN translation uses a configuration file, the name of
307 which must be specified in the Connection's "cqlfile" option.
309 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
310 function, which takes as its start-term parameter a ZOOM_query object
311 (which may have had either CQL or RPN set into it).
314 --- 2.1.10 2005/11/29
316 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
317 GFS to support this as well. Backend handler, bend_srw_update, does the
318 update work. Code contributed by Ko van der Sloot.
320 Allow retrieval of Search Result-1 information in ZOOM by the use of
321 options that are attached to a result set. ZOOM documentation updated
324 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
325 UTF-8 conversion. Patch by Raj Patel.
327 Added option -m to GFS to control formatting of timestamps in log file.
329 Added 'exit' as synonym for 'quit' in yaz-client
331 Added support for specifying SRW resultSetId + resultSetIdleTime in a
332 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
333 for the new members. Patch by Ko van der Sloot.
335 Added support for SRU POST. It is supported for content-type
336 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
338 Do not build the separate Multi-threaded (MT) library libyazthread.la.
339 Instead make the library libyaz.la multi-threaded. Threading as a whole
340 can still be disabled by configure option --disable-threads. Previosly,
341 with older GLIBCs there were problems with MT libs under Apache. This
342 has now been fixed a long time ago.
344 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
347 CQL module modified to be case insensitive for relations/indexes/operations.
349 Fixed bug in CQL transform code: incorrect value relationModifieder
352 Added 'show all' command for yaz-client which retrieves all results
355 Added new yaz-client, xmles, which takes a (private) OID and
356 a document to be sent as an extended service request.
358 Describe new yaz-client commands wait_response and set_auto_wait.
360 Increase TCP/IP listener backlog from 3 (which I am guessing was
361 copied from the SunOS manual entry way back when) so SOMAXCONN, so
362 that the socket will queue as many incoming connections as it's able
363 to handle ongoing connections. In other words, it will never now
364 refuse a connection that it would be able to handle merely because
365 it's not got around to accepting() enough of the pending connections
366 yet. This is the behaviour anyway under Linux, where the listen()
367 argument is ignored; but not under BSD and on systems such as
368 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
369 YAZ-based servers should now be uniform across operating systems in
372 yaz-marcdump uses 64-bit file access on some systems. This is enabled
373 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
374 This allows yaz-marcdump to read large MARC batches (>2 GB).
376 Modified all YAZ source files - except the source which is auto-generated
377 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
380 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
381 corresponding to the existing *_setl() function. These allow option
382 values containing arbitrary valuues.
384 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
385 ZOOM_resultset_sort() in new applications. Its behaviour is identical
386 except that it returns an indicator of whether or not the sort
387 criterion was accepted (0 for OK, -1 for invalid).
391 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
392 MARC output rather than returning "new" buffer.
394 yaz-client warns about unknown init options.
396 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
400 Added support for SRW sort in Generic Frontend Server. Patch
401 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
402 sortKeys - or NULL if none is provided.
404 Fixed bug #307: It was impossible to specify indefinite/no timeout
405 for ZOOM_event. Special timeout value -1 now means indefinite timeout
408 Added support for multiple languages and charsets to be specified in
409 ZOOM. Each charset/language is separated by a blank. If negotiation is
410 in effect in init-response, Option
411 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
412 Code based on patch by Vasiliy Osadchuk.
414 Fixed bug #306: infinite recursion that occurred when calling
415 yaz_log_level_init as the first call (before other log level or
418 Fixed bug in scan handling in front end server: if preferred-Position-In-
419 Response was non-present, a NULL pointer referece was performed.
423 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
424 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
425 now defined for all those error codes. So instead of putting 109 in
426 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
427 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
429 Modified the yaz-marcdump utility to skip garbage bytes between MARC
432 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
434 Program yaz-client now exits and produces an error message if multiple
435 Z39.50 servers are specified on the command line (none or one allowed
438 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
443 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
445 Fixed bug #272: Preserve spacing for CCL terms.
449 Added support for virtual hosts and multiple backend servers for
450 the YAZ frontend server. The configution is XML based and
451 support specificition of CQL to RPN mappings and explain information.
452 See section "Virtual Hosts" in the YAZ manual.
454 Extended OPAC display utility. OPAC display utility renders
455 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
456 to supplement yaz_marc_decode_wrbuf.
458 Fixed a bug in MARC decoder that could caused it to crash for some
459 invalid MARC records. More diagnostics and warnings where added in
460 XML output (warnings, etc are stored in comments).
462 --- 2.0.34 2005/02/08
464 Fixes for UNIX domain sockets. Bug #261.
466 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
468 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
469 Added yaz_marc_subfield_str which defines subfield lead string which is
470 used in YAZ_MARC_LINE format. Default string is blank+$. Added
471 yaz_marc_endline_str which defines end of fields string used in
472 YAZ_MARC_LINE format. Default string is newline.
474 Experimental support for MarcXChange. This format can be produced
475 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
476 http://www.bs.dk/standards/MarcXchange.xsd
478 Added yaz-client commands scansize that sets maximum number of
479 entries to be returned by scan.
481 --- 2.0.32 2005/01/11
483 Added support for SRW scan in yaz-client and Generic Frontend Server.
485 * Added whereInList member to SRW Scan Term.
487 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
489 Fixed NMEM system to return aligned blocks on the smallest boundaries
490 that are suitably aligned for all possible types on the particular
491 architecture YAZ is being built for.
493 --- 2.0.30 2005/01/04
495 Fixed numerious warnings that was issued with newer versions of GCC.
497 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
498 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
501 Make YAZ Generic Frontend Server slightly faster.
503 Enhance (and reduce) logging for Generic Frontend Server.
505 Revert YAZ log system so that it flushes every write operation
506 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
508 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
509 instead of LOG_, due to name clash with syslog(3). LOG_ are still
510 present. New applications should define YAZ_USE_NEW_LOG=1 - this
511 will effectively disable old definitions.
513 --- 2.0.28 2004/11/09
515 Added yaz_log_time_format which specifies log format using
518 Added yaz_log_module_level which returns mask for a module. Value
519 is non-zero mask a if module is enabled; zero if disabled.
521 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
522 in include/yaz/cql.h.
524 Fixed bug #176: Dont throw diagnostics on empty SRU args.
526 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
528 Fixed bug #172: RPM builds does not enable SSL.
530 Doxyfile.in part of dist. Doxyfile generated by configure.
532 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
533 are given and the corresponding component does not exist.
535 Extend CCL documentation in YAZ reference. Describe r=r.
537 --- 2.0.26 2004/10/01
539 Fixed MARC->MARCXML conversion to properly deal with
540 fields, subfields, indicators having non-ASCII characters.
542 Fixed MARC->MARCXML conversion so that ASCII control characters
543 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
546 Added YAZ GFS support for conversion from Z39.50 surrogate
547 diagnostics to SRW surrogate diagnostics.
549 Bug fix: YAZ GFS did not return schema in explainResponse.
551 --- 2.0.25 2004/09/30
553 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
554 now converts recordSchema to elementSetName as well as schema URI.
556 Fixed bug in COMSTACK that prevented HTTP request packages from being
559 --- 2.0.24 2004/09/29
561 Added CCL facility r=r "range" which is similar to r=o "ordered" but
562 does not require white-space before and after the dash in a range, e.g.
563 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
566 Fixed a few AC_TRY_LINK configure tests that did not operate properly
567 due to new GCC removing "redundant" code.
569 Added yaz-client commands scanpos and scanstep that sets preferred
570 position and step-size for scan.
572 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
574 Added CCL utility ccl_qual_buf which parses one or more CCL
575 spec lines in a buffer.
577 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
578 of name and value - ignoring empty lines and comments.
580 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
582 Added odr_get_element_path which returns current element path for an
583 ODR handle. This utility is useful in error handling or user-defined
586 Added ODR_PRINT utility odr_set_stream which is is a more generic
587 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
588 to a write function and pointer to close function. The close function - if
589 non-NULL - will be called during odr_destroy.
591 Fixed bug in CCL parser where truncation char was not removed from
592 right side when truncation=both was in effect.
594 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
597 --- 2.0.23 2004/08/11
599 Fix buffer overrun in CQL parser when dealing with proximity (%).
601 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
602 to UTF-8/UCS conversion is now only based on codetables.xml.
604 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
606 --- 2.0.22 2004/08/06
608 Add support for more "commit changes" in ZOOM (uses Extended Services).
610 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
613 Yet another small fix for configure of SSL.
615 --- 2.0.21 2004/05/14
617 Fix SSL libs for configure when --with-openssl=DIR is given.
619 --- 2.0.20 2004/05/10
621 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
623 SSL comstack now uses yaz.pem certificate file on server side
624 by default. Certificate filename can be configured by calling
625 comstack function cs_set_ssl_certificate_file before cs_bind is used.
627 Fix bug regarding multiple calls to ZOOM_connection_connect.
629 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
631 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
632 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
634 ZOOM now allows inspection of X509 peer certificate for verification.
635 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
637 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
638 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
639 as "modular" but it simplifies things.
641 Added cs_get_peer_certificate to that returns peer X509 PEM.
643 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
644 NULL if SSL is unavailable.
646 Documentation about MARC decoding tools.
648 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
650 --- 2.0.19 2004/03/30
652 Rename CHANGELOG to NEWS to follow GNU style packing.
654 Fix bug with missing initialization of member in init_diagnostics.
655 This bug affects threaded version of GFS server.
657 --- 2.0.18 2004/03/20
659 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
662 Ensure zlib.dll is packed with Windows install.
664 --- 2.0.17 2004/03/17
666 Fix encoding of xsd:string to use text instead of CDATA.
668 Fix endless loop in CQL parser with unbalanced ".
670 Use a more compact way to store MARC-8 conversion tables.
672 --- 2.0.16 2004/03/16 Debian only
674 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
677 Update CQL parser to use new CQL 1.1 modifiers for booleans and
682 --- 2.0.15 2004/03/01
684 Another fix for decoding of XML packed records.
686 --- 2.0.14 2004/02/25
688 Fixes for Chunked encoding. White space not ignored after length spec.
690 Update NS and use default NS for SRW diagnostic elements.
692 --- 2.0.13 2004/02/23
694 Implement ZOOM_resultset_cache_reset which resets record cache.
696 Implement ZOOM_resultset_sort which sorts a result set.
698 Implement chunked HTTP transfer.
700 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
702 --- 2.0.12 2004/02/16
704 Added member 'schema' to bend_explain_rr structure so that backend
705 can specify explain record identifier. Defaults to Zeerex 2.0.
707 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
709 --- 2.0.11 2004/02/16
711 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
714 Added init command for yaz-client which sends "extra" init request.
716 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
717 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
719 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
721 Make ZOOM error code for "invalid query".
723 Fixed compilation for SSL which wasn't properly enabled for all platforms.
725 --- 2.0.10 2004/02/05
727 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
730 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
732 Added option -p <file> to make Generic Frontend Server to write PID file.
734 Added option -D to put Generic Frontend Server in background on its own.
736 Make ZOOM C recognize option "password". If unset, "pass" is used
737 (for backwards compatibility).
739 Fixed a bug in Generic Frontend Server that could make it crash if a
740 client sets characterSetNegotation bit, but didn't pass negotiation stuff
743 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
744 Must be issued before open, in order to be in effect.
746 --- 2.0.9-6 2004/01/12 Debian/Windows
748 Make the SRU server more picky WRT unknown params, etc.
750 Bug fix: ZOOM scan response didn't return displayTerm - when present.
752 New YAZ client command, options, that sets Z39.50 options.
754 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
755 options from a string of tokens (one token for each option bit).
757 Update SRW diagnostic code messages.
759 --- 2.0.9-5 2004/01/07 Debian/Windows
761 Handle user defined stylesheet for SRW/SRU.
763 --- 2.0.9-4 2004/01/06 Debian/Windows
765 Fix bug in decoding of Content-Length.
767 --- 2.0.9-3 2004/01/06 Debian/Windows
769 Fix a bug with decoding of XML packed records.
771 --- 2.0.9-2 2004/01/05 Debian only
773 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
775 Fix bug in SRW/SRU diagnostics decoding.
779 Fixed bug in Generic Frontend Server which could drop records exceeding
780 preferred message size. Reported and fixed by Irina Dijour.
782 Fixed calculation of package size for structured records in Generic
783 Frontend Server. Reported and fixed by Irina Dijour.
785 Fixed namespace for SRW/SRU diagnostics.
787 Fixed SEGV in yaz-client that occured for HTTP connection errors.
791 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
792 this version is incompatible with version 1.0 and older YAZ SRW/SRU
795 CQL changes to reflect recent changes to the specification:
796 * Documentation talks about context sets instead of index sets.
797 * Documentation talks about indexes instead of qualifiers.
798 * The CQL-to-PQF transformer's configuration file now uses
799 "index.set.name = <attributes>" instead of the old form
800 "qualifier.set.name = <attributes>". (Both forms are still
801 understood but the latter is deprecated.)
802 * CQL terms with no explicit index specified are now interpreted as
803 cql.serverChoice instead of srw.serverChoice (which of course
804 behaves exactly the same.)
808 MARC conversion can now generate ISO2709 output in another
809 character set. yaz-marcdump uses this facility if you invoke it
812 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
813 functions from there can be used from C++.
817 Frontend server now transfers memory from decoded packages to stream
820 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
821 references to show up.
823 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
824 the ZOOM Abstract API. The older names for the same options are still
825 also supported for the benefit of old applications.
827 ZOOM-C supports "implementationId" and "implementationVersion" options
828 to go along with "implementationName". These allow the user code to
829 specify identification strings to be sent to servers.
830 Add OID for the new ExtLite attribute set.
832 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
833 as requested/supplid by Ere Maijala <ere@atp.fi>
835 For generic frontend server, reverse the order of
836 "toolkit-supplied / application-supplied" strings sent as implementationId,
837 Name and Version. Also, remove the spaces around the slash. This brings
838 the GFS in line with the behaviour of ZOOM-C on the client side.
840 Add function ZOOM_scanset_display_term.
842 yaz-client shows scan displayTerm if present.
844 Utility yaz-iconv is now installed by default along with the man page
847 Extend configure check for OpenSSL to use pkg-config where available (such
850 Incorporate patch by Morten Bogeskov which allows a Unix file socket
851 server to specify uid/gid/mask for socket using the format
852 unix:[user=uid,][group=gid,][umask=mask,]file=path
853 If file= is omitted the existing format is assumed, e.g.
855 in which case the mask is 0666 (rw for everybody).
857 Major restructure of YAZ source. All source in libyaz is in src directory.
858 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
859 util (utility programs such as ASN.1 compiler, yaz-marcdump).
861 Added man page for utility yaz-marcdump (used to be called marcdump).
862 yaz-marcdump is installed by 'make install'.
864 Fixed a memory leak in Generic Frontend Server that occurred when decoding
865 of incoming package failed.
867 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
869 Change prototype of odr_perror: add const to message string.
871 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
873 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
874 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
875 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
876 DNS lookup. There should not be any compatibility problems with this
877 assuming that blocking=1 or 0 is used.
879 Fix bad reference in UNIX comstack in function cs_addrstr.
881 Fix for compilation on AIX.
883 The generic front-end server (server/seshigh.c) now supports returning
884 Init diagnostics to the client in User-information-field, in
885 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
890 Allow any CQL relation (not just all,any,exact,scr).
892 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
893 that features the same UI.
895 Implemented command update0 in YAZ client which is equivalent to
896 update but uses old of Ext Update ASN.1.
898 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
899 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
900 Previously no OID was used for this info.
902 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
903 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
904 returns 'malformed search term' otherwise.
906 SortResponse member resultCount now set to NULL in sort handler of
909 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
912 Add three new utility functions for translating OIDs between various
913 formats -- symbolic name such as "Usmarc", minus-1-terminated int
914 arrays and dotted strings such as "1.2.840.10003.9.5.1":
915 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
916 char *oid_to_dotstring(const int *oid, char *oidbuf);
917 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
919 Reverted modifications for ES Update definition for z_IU0Update
920 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
921 is back to YAZ 2.0.2.
923 String value attributes for CCL parser.
925 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
926 which their FirstSearch server returns in Init responses, sometimes
927 carrying useful diagnostic information when Init fails. This has the
928 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
929 "z39.50/oclcui.asn", where its definition is somewhat different from
930 what OCLC document on their web-site, as required to interoperate with
933 Support for anonymous authentication in yaz-client. Use the command
936 * Fix the OID of the Index Data-local "admin" Extended Service from
937 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
938 the 1000, which indicates a locally-defined OID, was a mistake.
942 Fix CCL directive @case handling so that it affects string match for
943 both CCL keywords and qualifiers.
945 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
946 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
947 Decoder has been updated with ASN.1 changes as listed in
948 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
949 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
950 z_IUUpdate, remains unchanged.
952 ZOOM_record_get may now return a record in a specific character set.
953 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
954 "from" is the character set of record as returned by target. "to" is
955 the character set to be returned. If omitted, "to" is UTF-8.
957 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
959 New ODR utility, odr_getelement, which returns name of element for
960 which encoding/decoding failed.
962 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
963 in cases where a required element was omitted.
965 Bug fix: some MARC8 sequences were not converted.
967 New ZOOM option "step" which specifies number of records to be
968 retrieved in one chunk. Used in conjunction with "start" and "count".
970 SRW support for yaz-client. Use scheme http: to use it, e.g.
973 yaz-client no longer does (un)intelligent character set conversions
974 by default. Can be enabled with charset and marc_charset commands.
976 xmalloc trace fix for 64-bit systems such as DEC alpha.
978 Solaris 2.6 compile fix.
980 New function, cql_strerror() translates SRW error codes, as returned
981 by cql_transform_error(), into human-readable English strings. Used
982 in yaz-client diagnostics when appropriate.
984 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
985 converts it into a type-1 query which is sent to the server. This
986 makes CQL available for use with all Z-servers, as opposed to the tiny
987 minority that can handle CQL queries themselves.
991 New Debian package layout similar to the Redhat Package layout.
993 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
994 and search result respectively.
998 Redhat package is now several packages: libyaz (runtime libraries),
999 libyaz-devel (development and documentation, and yaz (utility programs).
1000 Package spec file by Morten Bøgeskov.
1002 New member 'schema' in struct bend_fetch_rr which the name of requested
1003 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1004 handler MAY set this to reflect the schema of the returned record.
1006 New member 'display_term' in struct scan_entry. GFS now sets member entries
1007 and allocates scan entries to be filled by user scan handler. In previous
1008 version, entries member was allocated by the scan handler. That still works,
1009 but the GFS will ignore member display_term - assuming it was NOT set by
1010 the handler. The fact that the GFS now allocates the entries both allows
1011 for new members and makes a scan handler easier to write.
1013 Fix CQL lex buffer overflow.
1015 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1016 SRU default recordPacking is string.
1018 SRU protocol support for frontend server.
1020 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1022 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1024 Added scan for the ZOOM shell (zoomsh).
1028 * String Identifers for Schemas (Amendment 5).
1029 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1030 Old definition for schema
1031 Odr_oid *schema; /* OPT */
1036 Z_InternationalString *uri;
1037 #define Z_Schema_oid 1
1038 #define Z_Schema_uri 2
1041 * resultCount parameter to Sort Response (Amendment 1).
1042 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1044 Support for SRW 1.0 over HTTP. This is an optional feature and
1045 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1048 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1049 on the same port. SRW SearchRetrieveRequests are mapped
1050 to bend_init,bend_search,bend_fetch,bend_close.
1052 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1054 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1055 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1057 ZOOM connections are SRW based if schem http is used for hostname
1058 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1059 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1061 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1062 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1063 distance=n, order=true/false, relation=le, prox unit=word. If
1064 n is omitted, distance 1 is used.
1066 Fixed problem with C compiler include path in wrong order.
1068 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1069 on Solaris. Patch from Ko van der Sloot.
1071 New MARC decode API. All new functions operate on a yaz_marc_t
1072 handle. The most important new functions are: yaz_marc_create,
1073 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1074 decode and destroy respectively. Decoder can produce formats
1075 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1076 include/yaz/marcdisp.h.
1078 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1079 to UTF-8, UCS-32, wchar_t or Latin-1.
1081 * Prototypes for yaz_iconv_-functions moved to separate header
1082 include/yaz/yaz-iconv.h.
1084 Make a few private functions 'static' in unix.c. This prevents
1085 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1087 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1088 are set when Init Response is received.
1090 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1091 but returns diagnostic set as well.
1093 New function yaz_strerror which is a portable wrapper for
1094 strerror/strerror_r/GetLastMessage.
1096 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1097 is returned for MARC. If type is "oai", then OAI MARC is returned.
1099 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1102 --- 1.9.2 2002/11/26
1104 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1106 Fix bad race conditions on SIGTERM and terminate gracefully in
1109 Move retrieval (data1) module to Zebra since nobody seems to be
1112 Add GRS-1 render for ZOOM using same format as yaz-client.
1114 --- 1.9.1 2002/10/05
1116 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1118 Fix broken ESpec handling in data1 module.
1120 SGML reader parses comments and makes them part of the data1 tree.
1122 Added several type casts so that YAZ compiles as C++ code.
1124 ZOOM didn't handle PDU encoding failures properly.
1126 Added more Bib-1 diagnostics (approved extensions).
1128 GNU configure: better check for iconv.
1130 More portable use of accept, getpeername. Check for socklen_t. Use
1131 int/size_t if socklen_t is not defined.
1135 PQF parser rejects bad queries - including those with extra
1136 characters in them. PQF parser used to silently ignore that.
1137 Cleaner API for PQF added, which allows you to get detailed
1138 error information for bad queries (see yaz/pquery.h).
1140 Fixed bug in ZOOM_record_get for type "database".
1142 Implemented mini iconv library supporting conversions between
1143 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1145 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1147 --- 1.8.9 2002/08/20
1149 Fixed ZOOM C record cache so that preferredRecordSyntax and
1150 elementSetName is used to check for already fetched records.
1152 --- 1.8.8 2002/08/02
1154 Added three members in bend_initrequest structure to facilitate
1155 character set negotiation.
1157 Fixed a bug in frontend server that could cause indefinite
1158 loops under rare conditions.
1160 Revised character set utilities (charneg.h) so that encoding
1161 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1163 For PQF, directive @term <type> sets term type for Scan/Search.
1164 Here <type> is general, string, numeric, null. The term type
1165 is inherited - just like @attr.
1167 New call odr_set_charset that sets character set conversion for
1168 international-strings on a ODR stream. Prototype is:
1169 int odr_set_charset(ODR o, const char *to, const char *from);
1170 The InternationalString is still represented as C string in YAZ
1171 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1172 won't). On the protocol level, you can use any encoding.
1174 Support for UNIX sockets in ZOOM.
1176 Solaris recv sometimes returns errno == ENOENT. It is treated as
1177 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1179 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1180 both client and server. Code by Morten Bøgeskov.
1182 --- 1.8.7 2002/05/22
1184 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1185 that they can be used directly from Visual Basic. You must recompile
1186 your windows APP if you're using ZOOM.
1188 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1189 Commands "lang" and "charset" sets language and character set respectively.
1190 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1191 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1193 Attributes from multiple CCL fields may be OR'ed rather than merged
1194 using directive "@field or". Fields are still merged by default -
1195 equivalent to "@field merge".
1197 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1200 Fixed bug in zget for parameter ExtendedServicesResponse.
1204 --- 1.8.6 2002/03/25
1206 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1208 Client displays USR.1:SearchResult-1 (hits per term).
1210 Additional Search Info for search in Generic Frontend Server.
1212 Fixed CCL parsing of "field=s".
1214 WIN32 installer - using the excellent NSIS software from nullsoft.
1216 Fixed CCL parsing of "field = - <number>".
1218 Added function yaz_marc_decode that decodes MARC for line mode
1219 display or XML (similar to that used by JZKit).
1221 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1222 Z39.50. But ISO/ILL was, however.
1224 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1225 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1227 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1228 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1230 --- 1.8.5 2002/02/03
1232 New YAZ client features: Command completion and new commands:
1233 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1234 Code provided by Jacob Poulsen.
1236 New call oid_trav, that visits all registered OIDs via callback.
1238 Function ZOOM_record_get now returns const char pointer rather than
1239 void pointer. It saves a lot of type casts.
1241 For YAZ client, command "auth" now allows you to set authentication
1242 in IdPass style. It is enabled when three tokens are given - order
1243 is user, group and password.
1245 Fix memory leaks in MARC record handling for ZOOM.
1247 New option for YAZ client, -k <kilobytes> that sets
1248 maximum record size. Similar to -k option for generic frontend
1249 server and yaz-ztest.
1251 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1253 Prefix query parser reports "fail" when bad attribute set is given.
1255 Fix in MARC decoder. Proximity logging. Fix for attribute set
1256 in scan handler for server. Patches by Shigeru Ishida.
1258 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1261 Configure option --with-openssl=<dir> now works when a directory is
1262 specified. Patch provided by Morten Bøgeskov.
1264 New option for YAZ client, -u <auth>, that sets authentication.
1266 ZOOM fix: error information was sometimes "missing", since error
1267 was cleared/reset too when it shouldn't.
1269 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1271 --- 1.8.4 2002/01/04
1273 Scan for ZOOM API. New object ZOOM_scanset. New functions
1274 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1275 ZOOM_scanset_destroy.
1277 New ZOOM function, ZOOM_connection_last_event, that returns type
1278 of last event (such as "receive data", "send data", "apdu received",
1281 New ZOOM option, schema, that specifies schema for retrieval.
1283 New CCL feature. Qualifiers can be aliases for one or more
1284 other qualifiers (if more than one is given, OR is used).
1286 ZOOM uses named result sets if target supports it.
1288 Two new YAZ client commands: . (dot, which sources a script of YAZ
1289 client commands), and ! (to execute shell command.). Implemented
1292 Working on Debian packages.
1294 --- 1.8.3 2001/11/19
1296 YAZ client enables named result sets only if target supports it.
1298 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1300 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1301 with key="host" to get same result.
1303 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1304 Function Z3950_resultset_record(s) returns references to records
1305 "owned" by resultset. To become owner use Z3950_record_clone.
1307 Function z_ext_record handles Extended Services. Thanks to
1310 --- 1.8.2 2001/11/12
1312 CCL Parser fix: ignore token comma when dealing with and-lists.
1314 Documentation updates for COMSTACK.
1316 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1317 Changed prototype Z3950_records. For some functions, int parameters
1318 were changed to size_t.
1320 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1323 New MARC decode/display function, marc_display_exl, which properly rejects
1324 non-ISO2709 records. YAZ client uses it.
1326 --- 1.8.1 2001/10/29
1328 Fix bug: local attribute set wasn't set correctly in PQF strings.
1332 * Old Z39.50 codecs no longer supported.
1334 Added ZOOM C binding. See http://zoom.z3950.org/
1336 Renamed states for COMSTACKs to avoid confusion with events.
1338 Implemented cs_look and proper cs_rcvconnect.
1340 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1342 Configure detects POSIX threads on OpenBSD.
1344 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1345 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1347 When error is returned from present handler, non-surrogate diagnostic
1348 is returned in present response (and fetch handler is no longer called).
1350 * Minor adjustments to pquery parser (PQF). Token characters may be
1351 escaped by using backslash (C-style).
1353 PQF parser allows string attribute values to be specified. For @attr,
1354 non-numeric characters after the equal-sign are treated as strings
1355 (e.g. @attr 9=title).
1357 CCL trunction character may be defined (@truncation in file)
1359 * function zget_ExtendedServicesRequest sets waitAction to
1360 waitIfPossible (was wait).
1362 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1365 CCL operator names may be set in field definition files (CCL_bibset).
1366 See ccl/bib1 for an example.
1368 Fixes in ASN.1 compiler for C++ compatibility.
1370 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1371 and "op_or" to avoid conflict with C++.
1373 Fixed problem with GNU readline detection on Redhat 7.0.
1375 Added step-size for Scan backend handler.
1377 Fixed bug that made the frontend server crash when no attribute
1378 set was specified for scan.
1380 Front-end server automatically switches to original working directory
1381 when installed as an NT service. Previously -w had to be specified to
1384 Added extended attributes for retrieval module (data1), so that data1
1385 records carry d1_readXML/SGML attributes. d1_read also supports
1386 null-data rules ( <tag/>)
1388 On UNIX when POSIX threads are available, a separate library libyazthread
1389 is created. Programmers should link with that library and the yaz library
1390 when using threads. The reason for the split was that some applications
1391 on Linux, such as Apache, doesn't work well when using shared objects that
1394 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1395 (or any frontend server) in SSL mode by specifying ssl: followed by
1396 address. Only tested on UNIX.
1398 Added feature for CCL module. Virtual structure s=al or s=ol generates
1399 and-list and or-list respectively instead of phrase search.
1403 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1404 log_mask_str. This was done to avoid name conflicts with other libraries
1405 (such as other PHP extensions).
1407 Added raw OID member for preferred record syntax (request_format_raw)
1408 and returned record syntax (output_format_raw) for backend fetch method.
1410 Config file yaz-config now accepts options so that it returns specific
1411 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1413 Shared library support for UNIX using GNU libtool.
1415 * Modified backend interface. Request/Response struct's replaced by
1416 one read/write C struct. For example bend_fetchrequest and
1417 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1418 Every handler - even search has to be registered in bend_init
1419 handler. This means that the YAZ library no longer refers to
1420 external functions and it makes it possible to make the whole
1421 thing a single DLL/SO.
1423 Added Segment handler for backend server.
1425 Added Zmbol/Zebra administrative functions to YAZ client.
1427 Threaded frontend server on UNIX (when POSIX Threads are available).
1428 Starting the server with option -T enables multi-threading.
1432 Added configure option --enable-comp/disable-comp to control use
1433 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1434 located in sub directory asn.
1436 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1437 in ${exec_prefix}/bin along with the other programs yaz-client and
1440 GNU automake used to maintain makefiles.
1442 Added several OID's.
1444 Changed retrieval module so that we can load records with no abstract
1445 syntax defined. Tagpaths in these records are fully composed of string
1448 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1452 On UNIX, the generated makefile now supports a proper 'make install'.
1453 The prefix can be set via GNU configure to set the install location
1454 (default is /usr/local).
1456 * YAZ programs client and ztest were renamed to yaz-client and
1457 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1458 locations, such as /usr/bin,/usr/local/bin,etc.
1460 * YAZ Header files were moved from include to include/yaz. YAZ Header
1461 files are referred to as include <yaz/log.h> rather than <log.h>.
1462 The YAZ include path (-I ..) is therefore the same as before. Programmers
1463 should update their #include statements or use -Ipath/include/yaz
1464 instead. The main motivation for doing this change is that YAZ header files
1465 can be installed in "standard" locations /usr/include,/usr/local/include
1466 without introducing conflicts, since ALL YAZ header files are stored
1467 in subdirectory yaz (under /usr/include for example).
1469 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1470 rather than project/workspace files. We switched because project files
1471 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1474 Changed name of logging function, logf, to yaz_log, to prevent name
1475 clash with some math-log functions. The YAZ header log.h defines logf
1476 to yaz_log (#define) so there should be no incompatibilities by this
1479 Added bend_start/bend_stop handlers for server. These handler are
1480 called on start/stop of server. For windows they are called whenever
1481 a service is started/stopped.
1483 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1484 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1485 in util/yc.tcl. The auto-generated C code structures are, in a few
1486 cases, incompatible with the old decoders. There are differences in the
1487 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1488 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1489 The preprocessor variable ASN_COMPILED is defined when the compiled
1490 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1491 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1492 wish to use the old encoders/decoders you can specify --disable-yc
1495 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1496 version so that it supports both new - and old version of DB Update
1498 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1499 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1500 change. The name parameter can be set to 0 in which no name is specified
1501 for the construction. The macros odr_implicit and odr_explicit sets name
1502 parameter to zero for the construction involved. New macros
1503 odr_implicit_tag and odr_explicit_tag are similar to the others,
1504 except that a name parameter is added. For programmers' that don't use
1505 ODR they probably only need to change the call to z_APDU and z_External.
1507 Added access control facility by interfacing the TCP wrapper library.
1508 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1509 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1510 name of the daemon and enables the access control as specified in
1511 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1513 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1514 den Dool <H.M.vdnDool@kub.nl>.
1516 Added reference ID parameter to most functions in server API - refer
1517 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1519 Changed name of ccl library to libccl.a (was ccl.a).
1521 Fixed bug in decoder for Explain (Category TargetInfo).
1523 Added support for GNU readline in client. Thanks to Jacob Poulsen
1524 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1526 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1527 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1528 IMPLEMENTATION! This change was made to the development version before
1529 the ZIG decided to retract the amendment. If any users MUST be
1530 compatible with the original Update definition, PLEASE CONTACT US, and
1531 we will include a separate definition corresponding to the old Update
1532 ES. Note that because of the change to the ASN.1 of the
1533 TaskPackageRecordStructure we cannot define a single structure that
1534 will support both versions.
1536 * Added const modifier to buffer parameter for some ODR/BER encoding
1537 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1538 completeWAIS, odr_dumpBER.
1540 Fixed bug in client.c which caused a crash when a scanResponse didn't
1541 contain positionOfTerm.
1543 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1544 * will cause an error in a client if a non-YAZ target sends both a
1545 * list of Scan entries and non-surrogate diagnostics.
1547 Retrieval module enhancements. Tag sets may be typed in the reference
1548 to it. From the .abs-file the "tagset" directive takes a third optional
1549 integer type for the tag set referenced. From a .tag-file the "include"
1550 directive takes a third optional type as well. The old "type" directive
1551 in the tag set itself is still recognized but acts as the default type
1554 Backend interface change. Individual Scan terms returned from bend_scan
1555 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1556 in include/backend.h.
1558 Retrieval module enhancements. Multiple tag sets and attribute sets may
1559 be specified in abstract syntax specs. Revised the error/warning for
1560 logging messages reported by the retrieval module when reading the
1563 Object Identifier system (oid_..) changed. The API is backwards
1564 compatible but the oid-routines now allocates new OID's when needed.
1565 Raw OID's may be specified in oid_getvalbyname.
1567 YAZ now uses GNU configure to generate Makefile(s).
1569 * Minor changes in some of the member names of DeleteResultSetRequest and
1570 DeleteResultSetResponse. See include/proto.h.
1572 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1573 and added member 'languages' in TargetInfo (which was missing).
1575 Changed the way attribute sets are handled in the retrieval
1576 module. These are now cached, just like the abstract syntaxes
1579 Changed YAZ so that it links with compiled ASN.1.
1581 Added Explain-schema definitions and mapping routines. The following
1582 Explain categories have been implemented: AttributeDetails,
1583 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1585 Fixed minor bug in Windows version of Server Library.
1587 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1589 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1591 Added EXTERNAL: UNIverse Resource Report (non-standard).
1593 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1594 ENUMERATED and SET OF.
1596 * Added 'const' to some of the char pointer arguments for the
1597 functions, data1_read_node, data1_getelementbytagname,
1598 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1601 Fixed bug in data1_insert_taggeddata - the last_child member of
1602 parent wasn't initialised.
1604 * Changed data1_read_record and data1_read_node so that the supplied
1605 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1606 doesn't refer to any parts of the "SGML"-buffer.
1608 Fixed bug in server library (Windows version of statserv_remove).
1610 * Changed code so that it compiles as C++. The type definition
1611 of Odr_fun which is a member of Odr_arm was changed. The result is,
1612 that an explicit typecast is needed for the fun pointer when
1613 using Odr_arm - as in:
1614 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1616 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1618 Implemented the new structured date and time definition as approved
1619 by the ZIG. Added schemaId element to the specificTag in Espec-1
1620 (also approved at the last ZIG). Thanks to RVDM.
1622 Added some Object identifiers (RVDM).
1624 Changed the Update Extended Service (RVDM).
1626 Added command "refid" to client which specifies referenceId for
1627 the following requests.
1629 Implemented extended service handling for server. See ztest.c
1630 for an example as well as backend.h. New handlers are registerd
1631 in the Init handler.
1633 * Changed interface for sort in server.
1635 Added new members to statserv_options_block. It allows a server
1636 to read options from another source than just the command line. Thanks
1637 to Charles Woodfield.
1639 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1640 renamed to zboolean. Some C++ compilers complained about the name.
1642 Minor changes to gils.abs. Added index 's' (sort) on title
1643 and date/time-last-modified.
1645 --- 1.4pl2 1998/1/30
1647 Fixed bug in server library regarding inetd mode (-i). This bug
1648 was introduced by release 1.4.
1650 --- 1.4pl1 1998/1/29
1652 Added sort facility in client and backend server interface.
1654 Fixed problem with dependencies in Makefile(s).
1656 Fixed bugs for encoders/decoders of extended services and
1659 Implemented sub-tree feature for schemas. Sub-trees are
1660 referenced in *.abs-files. See explain.abs for an example
1661 of the use of this feature.
1663 Modified bib1.att; local attributes for ANY didn't include
1664 ANY itself (only affects use of the retrieval module).
1666 Fixed bug in plain SGML reader in function data1_read_node:
1667 tags with prefix "var" was incorrectly interpreted as variants.
1669 Added feature "sub-schemas" to enable references to - and definitions
1670 of - group of elements.
1672 * Removed member parent from type data1_element (in data1.h).
1674 Implemented function odr_nullval() that returns the value of
1677 * Removed member num_children from data1_node (in data1.h).
1679 Made NT service interface part of the server library. The
1680 function statserv_main uses the NT service when required and
1681 calls the statserv_start / statserv_close routines.
1683 Routine zget_SearchRequest and zget_PresentRequest fills
1684 resultSetName/Id member with "default" instead of "Default".
1686 Fixed memory leak in server. Request queue member wasn't freed.
1688 Fixed nmem_exit so that memory is freed.
1692 Revised the CCL parser utility to be thread safe.
1694 Added function, oid_ent_to_oid, to replace the function
1695 oid_getoidbyent, which is not thread safe.
1697 * Added nmem_init and nmem_exit to initialize and release
1698 NMEM resources. Function nmem_init should be called once in the
1699 initial thread before NMEM/ODR is used. statserv.c and client.c
1700 have been changed accordingly. The change was necessary to make
1701 NMEM thread safe. The NMEM memory pool is shared amongst threads
1702 in a process. Unix-based applications will still work fine without
1705 Added NT Services interface for the the Z39.50 (statserv) Server.
1706 Refer to the ztest.c source on the usage.
1708 Windows 95/NT port using MSVC5.0. Project files are included in the
1711 * Defined new 'global' handle for the retrieval (data1) system. The
1712 new handled, data1_handle, describes the state of the data1 system.
1713 This handle is passed as first argument to virtually all
1714 data1 related routines. The functions data1_create and data1_destroy
1715 creates and destroys a data1 handle respectively.
1717 Added ODR encode stream member to all backend request structures
1718 init, search, scan etc. This stream should be used to allocate all
1719 memory used for the response when thread safe operation is needed.
1721 Changed the comstack utility, cs_addstr, to be thread safe. The
1722 returned hostname string returned by the function is now part the
1725 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1726 function. The cs_straddr takes a COMSTACK handle as argument, so this
1727 function must be used after cs_create and before bind/connect.
1728 This function is thread safe.
1730 Moved test server to 'ztest' directory - generic server code still
1731 in 'server' directory.
1733 Made prefix query (pquery.c) utility thread safe.
1735 Added new function modifier YAZ_EXPORT to 'export' public DLL
1736 functions when using windows (see include/yconfig.h).
1738 Added definitions to the OID database (util/oid.c) (RVDM).
1740 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1742 Added call to ccl_rpn_delete in client program.
1744 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1745 release of RPN structure.
1747 Added support for C++, headers uses extern "C" for public definitions.
1748 With input from RVDM.
1750 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1751 Thanks to Ronald van der Meer (RVDM).
1753 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1755 Added support for private extensions to the OID database
1756 (oid_setprivateoids()). Thanks to RVDM.
1758 Added optional, physical ANY (key replication)
1760 Fixed null-reference problem in GRS-1 output filter.
1762 Proximity operator added to Prefix Query Format (PQF).
1764 In test client command "base" accepts multiple databases.
1766 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1770 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1772 Smallish bug-fixes in the new encoders/decoders (explain).
1774 Bug fixed in DeleteRequest.
1776 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1778 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1780 Added SOIF syntax (using private OID for now) to retrieval module and client.
1782 Added Update extended service.
1784 Added SearchResult-1 additional info structure.
1786 Added optional CCL (ISO8777) interpreter as separate module. Available
1789 --- 1.2 1996/6/10 (1st anniversary release)
1791 Added Summary record syntax. Lightly tested.
1793 Added OPAC record syntax. Untested.
1795 Added ResourceReport service encoders/decoders. Untested.
1797 Fixed bug in z_Unit - wrong tagging on unitSystem.
1799 Fixed bug in the DiagRecs decoder.
1801 Added options for max PDU size and session timeout to frontend-server.
1803 Added documentation of query-language parsers and other supporting utilities.
1805 [frontend-server] Added Attribute set to the bend_scanrequest API.
1807 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1808 surrogate diagnostics were generated.
1810 [retrieval] Allow multiple local values for attribute.
1812 [retrieval] Allow multiple attributes per element in .abs files. index type.
1814 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1816 --- 1.1pl2 1996/4/10
1818 Minor changes, mostly specific to Zebra's requirements (retrieval)
1822 Repaired bug in frontend server when running multiple listening
1823 endpoints in dynamic mode.
1825 z_External() now won't break if a known, ASN.1 value comes encapsulated
1826 in an octet-string. The value will pass through unmodified in an Odr_oct.
1828 Added a bit of code to the demo client to decode & display
1829 ASN.1-structured records represented in the octet-aligned branch of
1830 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1832 Added z_ext_getentbyref() to the ASN module. Doc updated.
1834 * Completed the SCAN definition in the ASN module. This may break SCAN
1835 code based on older YAZ-versions at compile-time. The fix is easy -
1838 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1839 under the SCAN definition. Remember to initialize this, server-people.
1841 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1842 that this does not extend to ODR and ASN.
1844 Comstack allows insertion of established socket (primarily for
1845 inetd-operation of servers). Doc updated.
1847 Front-end server can now start from the inetd in TCP mode. Doc
1850 --- 1.0pl4 1996/1/24
1854 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1855 the rank and record number.
1857 Adjustments to the frontend server.
1859 Fixed diagnostic BER dumper. It ignored the file argument.
1863 Various changes to retrieval module.
1865 Changed the union discriminators of the protocol files from enums to
1866 ints paired with #defines.
1868 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1871 *Changed operator in the RPN structure to 'roperator', again to avoid a
1874 Fixed problems in Explain decoders/encoders.
1876 --- 1.0pl2 1995/12/6
1878 Memory bug in log module fixed.
1880 --- 1.0pl1 1995/12/5
1882 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1884 Bug in Explain DatabaseInfo module fixed.
1886 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1890 The shift to v1.0 signals that we now consider the *core* functionality
1891 of YAZ reasonably stable (the core being more or less equivalent to
1892 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1893 tested (Explain not at all - though that will happen soonish).
1895 Minor changes to code to support Windows port.
1897 Various minor changes after we're getting to use GRS-1 & co. more.
1899 Added Espec-1 format.
1901 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1902 of the protocol and it cannot be selected when encoding (maps into 'string'
1903 when decoding). Needed to talk to some servers.
1905 Demo client can request simple element set names.
1907 Added Diagnostic Format encoders/decoders.
1909 Added simple Close handling to frontend server (no hooks for resource
1910 reporting yet), and demonstration client.
1912 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1914 --- 1.0b3 1995/08/24
1916 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1917 handled incorrectly when records were requested in the searchResponse. This
1918 will only affect you if you use the frontend-server.
1920 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1921 Test-client will ask for and print GRS1. Ztest will return dummy records
1924 Added Explain encoders/decoders to the service-level API. Untested.
1926 Added Extended Services: Item Order encoders and decoders to the Service-
1927 level API. Untested. We could use a recent copy of the pertinent bits
1928 of the ILL protocol to add those bits.
1930 Added diagnostic format 1 encoders/decoders to the service-level API.
1933 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1934 odr_cons.c, which causes a more correct output.
1936 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1937 was always set to 0 when no records were requested in the searchRequest.
1939 * Added better external-handling. This shouldn't harm old code that
1940 *encodes* externals. It can break code that looks for a
1941 'single-ASN1-type' representation, since those types that are known
1942 are now decoded immediately. Look at the SUTRS sample code in
1943 seshigh.c and client.c. Documentation updated.
1945 Handling of structured records in bend_fetchresponse. Length -1 marks
1946 structured record, type is deduced from format field.
1948 --- 1.0b2 1995/06/27
1949 Fairly quick maintenance release to add SUTRS support.
1951 Fixed handling of SUTRS records in the demonstration client.
1953 * Added format field to the bend_fetchrequest and bend_fetchresponce
1954 structures of the backend API (frontend server). When the record is
1955 returned, the value of the format field is mapped to an OID. The
1956 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1957 of the record. The special value VAL_NONE in the bend_request means
1958 that no specific format was requested by the client. Documentation
1959 updated accordingly. Test server (ztest) will return a fixed dummy
1960 SUTRS record if your client requests SUTRS.
1962 Documentation updated accordingly.
1964 You can now set external libraries and RANLIB support in the top-level
1968 First public release.
