1 Added timings utility (yaz/timing.h)
5 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
8 Fixed bug #779: Rotation of apdu.log fails.
10 Fixed for character set conversions:
11 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
12 Honor G1 set in MARC-8 decoding.
16 Fixed bug #775: char conversion does not handle Alternative UTF-8
19 Implemented function yaz_marc_read_line which parses MARC line format
20 records. There is a wealth of formats out there. So far, this function
21 reads line records produced by yaz_marc_write_line.
23 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
24 more generic and easier to remember(!) options: -i format and -o format
25 which specifies input format and output format respectively - where
26 format is one of "marc", "marcxml", "line", "marcxchange".
28 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
29 does not print anything except warnings for records.
31 For yaz-marcdump, added support for MARC split into files (-s) with a given
34 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
35 spec, at http://www.loc.gov/standards/sru/record-update/
36 This has changed the binary layout of the following structs:
37 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
38 bend_update_rr . Patch by Ko van der Sloot.
40 Added GFS utility function bend_assoc_is_alive which returns 1 if
41 association is still alive (client is connected); 0 otherwise (client
42 closed connection). This allows busy servers to stop working for
45 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
46 been a separate piece of software. This version of ziffy has been modified
47 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
49 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
51 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
52 Client code may now interrogate options such as "init_opt_sort" to
53 find out whether the server claims to support various options.
57 Added utilities yaz_{set,get}_esn to set/get element set name from
60 Removed the build of libyazthread.la. The libyaz.so is the threaded version
61 of YAZ and has been so since YAZ 2.1.10.
63 Implemented ZOOM_record_error which returns error information for
64 record (surrogate diagnostic).
68 Updates for SRU Update by Ko van der Sloot:
69 1. Changed name from "operation" to "action"
70 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
71 versions in the code, marked as 'backward compatible'.
72 3. Added diagnostics for SRU Update.
74 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
76 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
78 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
80 For GFS, fixed problem with SRU diagnostic 'First record position out of
81 range' being issued for 0 hits.
83 zoomtst10 part of Windows Build.
87 Implemented yaz_filepath_comp which splits a path into file path
88 components (required by Zebra 2.0.3+).
90 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
91 BSD inspired license until now so this should not have any real impact on
92 anybody. See http://www.opensource.org/licenses/bsd-license.php
94 Fixed bug #687: Missing log lines.
96 Fixed bug #678: CQL to PQF translation does not preserve double-quote
99 Fixed bug #689: SRU diagnostics to be added.
101 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
102 whether a connection is idle (no more work do do).
104 --- 2.1.34 2006/10/04
106 Change type of optval from long to int for invocation of setsockopt with
107 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
109 Added support for specifying the max log file size for the Generic
110 Frontend Server. The size is given with option -r.
112 --- 2.1.32 2006/09/21
114 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
116 --- 2.1.30 2006/09/17
118 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
121 Fixed bug in Generic Frontend Server that could cause a server to stop
122 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
124 For the generic frontend server, the maximum record size is used as maximum
125 size of incoming packages (SRU + Z39.50). The value until was previously
126 only used in Z39.50 Init negotiation and, later, in a session controlled
127 sizes of records returned. This is controlled using -k option. It can be
128 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
130 --- 2.1.28 2006/09/04
132 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
135 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
137 New option for yaz-marcdump -lpos=value which allows setting a portion
138 of MARC header to a certain value.
140 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
142 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
143 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
145 --- 2.1.26 2006/08/15
147 Fixed problem with SRU mode type (soap, get, post) for yaz-client
150 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
152 --- 2.1.24 2006/08/08
154 Fixed MARC ISO2709 encoding routines to deal with character set
157 Minor changes to GFS logging. Database included in search request log
160 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
161 cached/multiple records.
163 Shared libraries are built by default on Unix+configure.
165 Changed cql2pqf transformation to use a different evaluation order. The
166 new order is: always, relation, structure, position, truncation, index
167 and relationModifier. Old order was: always, relation, relationModifier,
168 structure, index, position, truncation. Note that the the latter ones
169 override former ones for identical attributes.. The new scheme means that
170 it is possible to override any existing attribute with a relationModifier.
171 And also that it is possible to override everything for the index rule
172 (except the ones listed in relationModifier). No order is perfect but this
173 one, we believe, covers more real cases.. The "always" should have been
174 called "default", since the attributes there can be overridden with all
177 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
178 compilation phase, but also for yaz-config --cflags output. This allows
179 us to have public headers with Libxml2 stuff in them . It should also,
180 eventually, make Libxml2 checks redundant in packages using YAZ, such
183 --- 2.1.22 2006/06/15
185 Changed SRU update structure bend_update_rr so that SRU diagnostics are
186 stored in uri, message and details.. Previously diagnostics were stored
187 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
188 compatibility.. but he's probably the only one affected, so.
190 Added support for CCL, compiled on the client side, in ZOOM-C. This
191 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
192 input; the resulting query objects can be used for for searching with
193 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
195 YAZ' configure searches for OpenSSL by default.
197 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
198 SL_CTX_use_certificate_file. See
199 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
200 for more info. Thanks to Ko van der Sloot.
202 --- 2.1.20 2006/06/02
204 Bug #600: SRU GET, POST support for yaz-client. Introduced
205 command 'sru' which selects method SOAP/GET/POST.
207 Allow missingValueAction to be specified for the sortspec string -
208 function yaz_sort_spec. By default, the missing value action is null.
209 Use ! to specify "abort". Use = followed by stringvalue to specify default
212 Ensured that Present-handler (if defined) is called in GFS before any call to
213 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
214 searchRetrieve requests.
216 Documentation for YAZ is now based on the Docbook XML/XSLT using
217 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
218 is no longer depending on jade/openjade or docbook-to-man scripts.
219 PDF is no longer part of the distribution - but can optionally be
220 made using DSSSL/jadetex or FOP.
222 Added retrieval handling support in Generic Frontend Server to support
223 conversion between MARC/XML as well as XSLTtransforms. See
224 etc/yazgfs.xml for an example.
226 Added Authentication support to Generic Frontend Server in SRU
227 mode. Authentication using HTTP Basic is supported, as is the use
228 of 'x-username' and 'x-password' parameters in the request itself.
230 Added support for a new character set MARC8s identical to MARC8 except
231 that it converts combined characters to single Unicode characters in the
232 Latin-1 range (when possible).
234 --- 2.1.18 2006/04/24
236 ASN.1 compiler 0.4: generates brief Doxygen file header for
237 generated .h/.c files.
239 Utility yaz_iconv now supports conversion to MARC-8.
241 New facilities for the MARC module. The reading - and writing of
242 content are separate methods for the yaz_marc_t handle. The following
243 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
244 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
245 format). Write functions have prefix yaz_marc_write_.. The existing
246 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
247 available. Removed support for OAI-MARC and simplexml (not the
248 simplexml from PHP5).
250 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
251 to be returned for this connection.
253 --- 2.1.16 2006/03/31
255 Allow multiple languages and charsets to be specified with
256 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
257 negcharset iso-8859-1,utf-8
259 Translation of proximity nodes from CQL into PQF now works.
261 Moved to automake 1.8, 1.9.
263 Added function yaz_log_set_handler which allows a log handler to be
264 installed. This handler will be called for all log messages. Output
265 to file is also produced; but that can be disabled by passing NULL
266 fname to yaz_log_init_file.
268 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
270 For SRW (including GFS), accept application/soap+xml as content-type
273 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
274 produces NO stylesheet reference even if a default stylesheet is specified
277 --- 2.1.14 2006/03/14
279 Updated Windows package to include yazd.dll + yazd.lib for the
280 Development component.
282 If the environment variable YAZ_LOG is set, then it is used as a
283 string indicating the default level of logging to use if not
284 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
285 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
286 used as before. So, for example, to omit warnings from YAZ logging,
289 cql_transform() now map structure and other attributes before indexes,
290 so that index-specific structures and other attributes can override
291 defaults. So now a combination of mapping specifications such as:
293 index.dc.date = 1=date-modified 4=5
294 does the right thing.
296 cql_transform() now also respects the "always" mapping specification,
297 which establishes an initial set of attributes to be used for all
298 terms except where overridden by more specific attributes associated
299 with the index, relation or modifier.
301 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
302 which mode to use; one of "post", "get" or "soap" (SRW, default).
304 Fixes for yaz_iconv routines: changed trie-based character set conversions
305 to use only non-negative values for bit fields due to Sun's C compiler not
306 supporting negative values.
308 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
309 sequences where not read correctly. Fix by Rustam Usmanov.
311 Updated win/makefile to use options, settings which makes things
312 compile with VS C 2005.
314 --- 2.1.12 2006/02/01
316 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
318 In ZOOM socket code, use select instead of poll on MacOSX.
320 ZOOM-C now support client-side compilation of CQL into RPN that is
321 sent to the server, enabling CQL to be used against all Z39.50
322 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
323 ZOOM_query object, and submit it using ZOOM_connection_search().
324 The CQL-to-RPN translation uses a configuration file, the name of
325 which must be specified in the Connection's "cqlfile" option.
327 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
328 function, which takes as its start-term parameter a ZOOM_query object
329 (which may have had either CQL or RPN set into it).
332 --- 2.1.10 2005/11/29
334 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
335 GFS to support this as well. Backend handler, bend_srw_update, does the
336 update work. Code contributed by Ko van der Sloot.
338 Allow retrieval of Search Result-1 information in ZOOM by the use of
339 options that are attached to a result set. ZOOM documentation updated
342 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
343 UTF-8 conversion. Patch by Raj Patel.
345 Added option -m to GFS to control formatting of timestamps in log file.
347 Added 'exit' as synonym for 'quit' in yaz-client
349 Added support for specifying SRW resultSetId + resultSetIdleTime in a
350 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
351 for the new members. Patch by Ko van der Sloot.
353 Added support for SRU POST. It is supported for content-type
354 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
356 Do not build the separate Multi-threaded (MT) library libyazthread.la.
357 Instead make the library libyaz.la multi-threaded. Threading as a whole
358 can still be disabled by configure option --disable-threads. Previosly,
359 with older GLIBCs there were problems with MT libs under Apache. This
360 has now been fixed a long time ago.
362 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
365 CQL module modified to be case insensitive for relations/indexes/operations.
367 Fixed bug in CQL transform code: incorrect value relationModifieder
370 Added 'show all' command for yaz-client which retrieves all results
373 Added new yaz-client, xmles, which takes a (private) OID and
374 a document to be sent as an extended service request.
376 Describe new yaz-client commands wait_response and set_auto_wait.
378 Increase TCP/IP listener backlog from 3 (which I am guessing was
379 copied from the SunOS manual entry way back when) so SOMAXCONN, so
380 that the socket will queue as many incoming connections as it's able
381 to handle ongoing connections. In other words, it will never now
382 refuse a connection that it would be able to handle merely because
383 it's not got around to accepting() enough of the pending connections
384 yet. This is the behaviour anyway under Linux, where the listen()
385 argument is ignored; but not under BSD and on systems such as
386 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
387 YAZ-based servers should now be uniform across operating systems in
390 yaz-marcdump uses 64-bit file access on some systems. This is enabled
391 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
392 This allows yaz-marcdump to read large MARC batches (>2 GB).
394 Modified all YAZ source files - except the source which is auto-generated
395 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
398 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
399 corresponding to the existing *_setl() function. These allow option
400 values containing arbitrary valuues.
402 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
403 ZOOM_resultset_sort() in new applications. Its behaviour is identical
404 except that it returns an indicator of whether or not the sort
405 criterion was accepted (0 for OK, -1 for invalid).
409 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
410 MARC output rather than returning "new" buffer.
412 yaz-client warns about unknown init options.
414 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
418 Added support for SRW sort in Generic Frontend Server. Patch
419 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
420 sortKeys - or NULL if none is provided.
422 Fixed bug #307: It was impossible to specify indefinite/no timeout
423 for ZOOM_event. Special timeout value -1 now means indefinite timeout
426 Added support for multiple languages and charsets to be specified in
427 ZOOM. Each charset/language is separated by a blank. If negotiation is
428 in effect in init-response, Option
429 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
430 Code based on patch by Vasiliy Osadchuk.
432 Fixed bug #306: infinite recursion that occurred when calling
433 yaz_log_level_init as the first call (before other log level or
436 Fixed bug in scan handling in front end server: if preferred-Position-In-
437 Response was non-present, a NULL pointer referece was performed.
441 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
442 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
443 now defined for all those error codes. So instead of putting 109 in
444 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
445 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
447 Modified the yaz-marcdump utility to skip garbage bytes between MARC
450 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
452 Program yaz-client now exits and produces an error message if multiple
453 Z39.50 servers are specified on the command line (none or one allowed
456 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
461 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
463 Fixed bug #272: Preserve spacing for CCL terms.
467 Added support for virtual hosts and multiple backend servers for
468 the YAZ frontend server. The configution is XML based and
469 support specificition of CQL to RPN mappings and explain information.
470 See section "Virtual Hosts" in the YAZ manual.
472 Extended OPAC display utility. OPAC display utility renders
473 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
474 to supplement yaz_marc_decode_wrbuf.
476 Fixed a bug in MARC decoder that could caused it to crash for some
477 invalid MARC records. More diagnostics and warnings where added in
478 XML output (warnings, etc are stored in comments).
480 --- 2.0.34 2005/02/08
482 Fixes for UNIX domain sockets. Bug #261.
484 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
486 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
487 Added yaz_marc_subfield_str which defines subfield lead string which is
488 used in YAZ_MARC_LINE format. Default string is blank+$. Added
489 yaz_marc_endline_str which defines end of fields string used in
490 YAZ_MARC_LINE format. Default string is newline.
492 Experimental support for MarcXChange. This format can be produced
493 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
494 http://www.bs.dk/standards/MarcXchange.xsd
496 Added yaz-client commands scansize that sets maximum number of
497 entries to be returned by scan.
499 --- 2.0.32 2005/01/11
501 Added support for SRW scan in yaz-client and Generic Frontend Server.
503 * Added whereInList member to SRW Scan Term.
505 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
507 Fixed NMEM system to return aligned blocks on the smallest boundaries
508 that are suitably aligned for all possible types on the particular
509 architecture YAZ is being built for.
511 --- 2.0.30 2005/01/04
513 Fixed numerious warnings that was issued with newer versions of GCC.
515 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
516 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
519 Make YAZ Generic Frontend Server slightly faster.
521 Enhance (and reduce) logging for Generic Frontend Server.
523 Revert YAZ log system so that it flushes every write operation
524 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
526 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
527 instead of LOG_, due to name clash with syslog(3). LOG_ are still
528 present. New applications should define YAZ_USE_NEW_LOG=1 - this
529 will effectively disable old definitions.
531 --- 2.0.28 2004/11/09
533 Added yaz_log_time_format which specifies log format using
536 Added yaz_log_module_level which returns mask for a module. Value
537 is non-zero mask a if module is enabled; zero if disabled.
539 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
540 in include/yaz/cql.h.
542 Fixed bug #176: Dont throw diagnostics on empty SRU args.
544 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
546 Fixed bug #172: RPM builds does not enable SSL.
548 Doxyfile.in part of dist. Doxyfile generated by configure.
550 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
551 are given and the corresponding component does not exist.
553 Extend CCL documentation in YAZ reference. Describe r=r.
555 --- 2.0.26 2004/10/01
557 Fixed MARC->MARCXML conversion to properly deal with
558 fields, subfields, indicators having non-ASCII characters.
560 Fixed MARC->MARCXML conversion so that ASCII control characters
561 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
564 Added YAZ GFS support for conversion from Z39.50 surrogate
565 diagnostics to SRW surrogate diagnostics.
567 Bug fix: YAZ GFS did not return schema in explainResponse.
569 --- 2.0.25 2004/09/30
571 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
572 now converts recordSchema to elementSetName as well as schema URI.
574 Fixed bug in COMSTACK that prevented HTTP request packages from being
577 --- 2.0.24 2004/09/29
579 Added CCL facility r=r "range" which is similar to r=o "ordered" but
580 does not require white-space before and after the dash in a range, e.g.
581 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
584 Fixed a few AC_TRY_LINK configure tests that did not operate properly
585 due to new GCC removing "redundant" code.
587 Added yaz-client commands scanpos and scanstep that sets preferred
588 position and step-size for scan.
590 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
592 Added CCL utility ccl_qual_buf which parses one or more CCL
593 spec lines in a buffer.
595 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
596 of name and value - ignoring empty lines and comments.
598 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
600 Added odr_get_element_path which returns current element path for an
601 ODR handle. This utility is useful in error handling or user-defined
604 Added ODR_PRINT utility odr_set_stream which is is a more generic
605 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
606 to a write function and pointer to close function. The close function - if
607 non-NULL - will be called during odr_destroy.
609 Fixed bug in CCL parser where truncation char was not removed from
610 right side when truncation=both was in effect.
612 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
615 --- 2.0.23 2004/08/11
617 Fix buffer overrun in CQL parser when dealing with proximity (%).
619 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
620 to UTF-8/UCS conversion is now only based on codetables.xml.
622 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
624 --- 2.0.22 2004/08/06
626 Add support for more "commit changes" in ZOOM (uses Extended Services).
628 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
631 Yet another small fix for configure of SSL.
633 --- 2.0.21 2004/05/14
635 Fix SSL libs for configure when --with-openssl=DIR is given.
637 --- 2.0.20 2004/05/10
639 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
641 SSL comstack now uses yaz.pem certificate file on server side
642 by default. Certificate filename can be configured by calling
643 comstack function cs_set_ssl_certificate_file before cs_bind is used.
645 Fix bug regarding multiple calls to ZOOM_connection_connect.
647 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
649 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
650 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
652 ZOOM now allows inspection of X509 peer certificate for verification.
653 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
655 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
656 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
657 as "modular" but it simplifies things.
659 Added cs_get_peer_certificate to that returns peer X509 PEM.
661 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
662 NULL if SSL is unavailable.
664 Documentation about MARC decoding tools.
666 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
668 --- 2.0.19 2004/03/30
670 Rename CHANGELOG to NEWS to follow GNU style packing.
672 Fix bug with missing initialization of member in init_diagnostics.
673 This bug affects threaded version of GFS server.
675 --- 2.0.18 2004/03/20
677 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
680 Ensure zlib.dll is packed with Windows install.
682 --- 2.0.17 2004/03/17
684 Fix encoding of xsd:string to use text instead of CDATA.
686 Fix endless loop in CQL parser with unbalanced ".
688 Use a more compact way to store MARC-8 conversion tables.
690 --- 2.0.16 2004/03/16 Debian only
692 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
695 Update CQL parser to use new CQL 1.1 modifiers for booleans and
700 --- 2.0.15 2004/03/01
702 Another fix for decoding of XML packed records.
704 --- 2.0.14 2004/02/25
706 Fixes for Chunked encoding. White space not ignored after length spec.
708 Update NS and use default NS for SRW diagnostic elements.
710 --- 2.0.13 2004/02/23
712 Implement ZOOM_resultset_cache_reset which resets record cache.
714 Implement ZOOM_resultset_sort which sorts a result set.
716 Implement chunked HTTP transfer.
718 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
720 --- 2.0.12 2004/02/16
722 Added member 'schema' to bend_explain_rr structure so that backend
723 can specify explain record identifier. Defaults to Zeerex 2.0.
725 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
727 --- 2.0.11 2004/02/16
729 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
732 Added init command for yaz-client which sends "extra" init request.
734 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
735 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
737 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
739 Make ZOOM error code for "invalid query".
741 Fixed compilation for SSL which wasn't properly enabled for all platforms.
743 --- 2.0.10 2004/02/05
745 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
748 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
750 Added option -p <file> to make Generic Frontend Server to write PID file.
752 Added option -D to put Generic Frontend Server in background on its own.
754 Make ZOOM C recognize option "password". If unset, "pass" is used
755 (for backwards compatibility).
757 Fixed a bug in Generic Frontend Server that could make it crash if a
758 client sets characterSetNegotation bit, but didn't pass negotiation stuff
761 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
762 Must be issued before open, in order to be in effect.
764 --- 2.0.9-6 2004/01/12 Debian/Windows
766 Make the SRU server more picky WRT unknown params, etc.
768 Bug fix: ZOOM scan response didn't return displayTerm - when present.
770 New YAZ client command, options, that sets Z39.50 options.
772 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
773 options from a string of tokens (one token for each option bit).
775 Update SRW diagnostic code messages.
777 --- 2.0.9-5 2004/01/07 Debian/Windows
779 Handle user defined stylesheet for SRW/SRU.
781 --- 2.0.9-4 2004/01/06 Debian/Windows
783 Fix bug in decoding of Content-Length.
785 --- 2.0.9-3 2004/01/06 Debian/Windows
787 Fix a bug with decoding of XML packed records.
789 --- 2.0.9-2 2004/01/05 Debian only
791 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
793 Fix bug in SRW/SRU diagnostics decoding.
797 Fixed bug in Generic Frontend Server which could drop records exceeding
798 preferred message size. Reported and fixed by Irina Dijour.
800 Fixed calculation of package size for structured records in Generic
801 Frontend Server. Reported and fixed by Irina Dijour.
803 Fixed namespace for SRW/SRU diagnostics.
805 Fixed SEGV in yaz-client that occured for HTTP connection errors.
809 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
810 this version is incompatible with version 1.0 and older YAZ SRW/SRU
813 CQL changes to reflect recent changes to the specification:
814 * Documentation talks about context sets instead of index sets.
815 * Documentation talks about indexes instead of qualifiers.
816 * The CQL-to-PQF transformer's configuration file now uses
817 "index.set.name = <attributes>" instead of the old form
818 "qualifier.set.name = <attributes>". (Both forms are still
819 understood but the latter is deprecated.)
820 * CQL terms with no explicit index specified are now interpreted as
821 cql.serverChoice instead of srw.serverChoice (which of course
822 behaves exactly the same.)
826 MARC conversion can now generate ISO2709 output in another
827 character set. yaz-marcdump uses this facility if you invoke it
830 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
831 functions from there can be used from C++.
835 Frontend server now transfers memory from decoded packages to stream
838 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
839 references to show up.
841 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
842 the ZOOM Abstract API. The older names for the same options are still
843 also supported for the benefit of old applications.
845 ZOOM-C supports "implementationId" and "implementationVersion" options
846 to go along with "implementationName". These allow the user code to
847 specify identification strings to be sent to servers.
848 Add OID for the new ExtLite attribute set.
850 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
851 as requested/supplid by Ere Maijala <ere@atp.fi>
853 For generic frontend server, reverse the order of
854 "toolkit-supplied / application-supplied" strings sent as implementationId,
855 Name and Version. Also, remove the spaces around the slash. This brings
856 the GFS in line with the behaviour of ZOOM-C on the client side.
858 Add function ZOOM_scanset_display_term.
860 yaz-client shows scan displayTerm if present.
862 Utility yaz-iconv is now installed by default along with the man page
865 Extend configure check for OpenSSL to use pkg-config where available (such
868 Incorporate patch by Morten Bogeskov which allows a Unix file socket
869 server to specify uid/gid/mask for socket using the format
870 unix:[user=uid,][group=gid,][umask=mask,]file=path
871 If file= is omitted the existing format is assumed, e.g.
873 in which case the mask is 0666 (rw for everybody).
875 Major restructure of YAZ source. All source in libyaz is in src directory.
876 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
877 util (utility programs such as ASN.1 compiler, yaz-marcdump).
879 Added man page for utility yaz-marcdump (used to be called marcdump).
880 yaz-marcdump is installed by 'make install'.
882 Fixed a memory leak in Generic Frontend Server that occurred when decoding
883 of incoming package failed.
885 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
887 Change prototype of odr_perror: add const to message string.
889 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
891 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
892 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
893 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
894 DNS lookup. There should not be any compatibility problems with this
895 assuming that blocking=1 or 0 is used.
897 Fix bad reference in UNIX comstack in function cs_addrstr.
899 Fix for compilation on AIX.
901 The generic front-end server (server/seshigh.c) now supports returning
902 Init diagnostics to the client in User-information-field, in
903 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
908 Allow any CQL relation (not just all,any,exact,scr).
910 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
911 that features the same UI.
913 Implemented command update0 in YAZ client which is equivalent to
914 update but uses old of Ext Update ASN.1.
916 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
917 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
918 Previously no OID was used for this info.
920 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
921 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
922 returns 'malformed search term' otherwise.
924 SortResponse member resultCount now set to NULL in sort handler of
927 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
930 Add three new utility functions for translating OIDs between various
931 formats -- symbolic name such as "Usmarc", minus-1-terminated int
932 arrays and dotted strings such as "1.2.840.10003.9.5.1":
933 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
934 char *oid_to_dotstring(const int *oid, char *oidbuf);
935 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
937 Reverted modifications for ES Update definition for z_IU0Update
938 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
939 is back to YAZ 2.0.2.
941 String value attributes for CCL parser.
943 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
944 which their FirstSearch server returns in Init responses, sometimes
945 carrying useful diagnostic information when Init fails. This has the
946 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
947 "z39.50/oclcui.asn", where its definition is somewhat different from
948 what OCLC document on their web-site, as required to interoperate with
951 Support for anonymous authentication in yaz-client. Use the command
954 * Fix the OID of the Index Data-local "admin" Extended Service from
955 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
956 the 1000, which indicates a locally-defined OID, was a mistake.
960 Fix CCL directive @case handling so that it affects string match for
961 both CCL keywords and qualifiers.
963 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
964 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
965 Decoder has been updated with ASN.1 changes as listed in
966 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
967 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
968 z_IUUpdate, remains unchanged.
970 ZOOM_record_get may now return a record in a specific character set.
971 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
972 "from" is the character set of record as returned by target. "to" is
973 the character set to be returned. If omitted, "to" is UTF-8.
975 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
977 New ODR utility, odr_getelement, which returns name of element for
978 which encoding/decoding failed.
980 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
981 in cases where a required element was omitted.
983 Bug fix: some MARC8 sequences were not converted.
985 New ZOOM option "step" which specifies number of records to be
986 retrieved in one chunk. Used in conjunction with "start" and "count".
988 SRW support for yaz-client. Use scheme http: to use it, e.g.
991 yaz-client no longer does (un)intelligent character set conversions
992 by default. Can be enabled with charset and marc_charset commands.
994 xmalloc trace fix for 64-bit systems such as DEC alpha.
996 Solaris 2.6 compile fix.
998 New function, cql_strerror() translates SRW error codes, as returned
999 by cql_transform_error(), into human-readable English strings. Used
1000 in yaz-client diagnostics when appropriate.
1002 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1003 converts it into a type-1 query which is sent to the server. This
1004 makes CQL available for use with all Z-servers, as opposed to the tiny
1005 minority that can handle CQL queries themselves.
1007 --- 2.0.2 2003/04/28
1009 New Debian package layout similar to the Redhat Package layout.
1011 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1012 and search result respectively.
1014 --- 2.0.1 2003/04/25
1016 Redhat package is now several packages: libyaz (runtime libraries),
1017 libyaz-devel (development and documentation, and yaz (utility programs).
1018 Package spec file by Morten Bøgeskov.
1020 New member 'schema' in struct bend_fetch_rr which the name of requested
1021 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1022 handler MAY set this to reflect the schema of the returned record.
1024 New member 'display_term' in struct scan_entry. GFS now sets member entries
1025 and allocates scan entries to be filled by user scan handler. In previous
1026 version, entries member was allocated by the scan handler. That still works,
1027 but the GFS will ignore member display_term - assuming it was NOT set by
1028 the handler. The fact that the GFS now allocates the entries both allows
1029 for new members and makes a scan handler easier to write.
1031 Fix CQL lex buffer overflow.
1033 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1034 SRU default recordPacking is string.
1036 SRU protocol support for frontend server.
1038 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1040 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1042 Added scan for the ZOOM shell (zoomsh).
1046 * String Identifers for Schemas (Amendment 5).
1047 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1048 Old definition for schema
1049 Odr_oid *schema; /* OPT */
1054 Z_InternationalString *uri;
1055 #define Z_Schema_oid 1
1056 #define Z_Schema_uri 2
1059 * resultCount parameter to Sort Response (Amendment 1).
1060 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1062 Support for SRW 1.0 over HTTP. This is an optional feature and
1063 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1066 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1067 on the same port. SRW SearchRetrieveRequests are mapped
1068 to bend_init,bend_search,bend_fetch,bend_close.
1070 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1072 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1073 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1075 ZOOM connections are SRW based if schem http is used for hostname
1076 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1077 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1079 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1080 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1081 distance=n, order=true/false, relation=le, prox unit=word. If
1082 n is omitted, distance 1 is used.
1084 Fixed problem with C compiler include path in wrong order.
1086 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1087 on Solaris. Patch from Ko van der Sloot.
1089 New MARC decode API. All new functions operate on a yaz_marc_t
1090 handle. The most important new functions are: yaz_marc_create,
1091 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1092 decode and destroy respectively. Decoder can produce formats
1093 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1094 include/yaz/marcdisp.h.
1096 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1097 to UTF-8, UCS-32, wchar_t or Latin-1.
1099 * Prototypes for yaz_iconv_-functions moved to separate header
1100 include/yaz/yaz-iconv.h.
1102 Make a few private functions 'static' in unix.c. This prevents
1103 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1105 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1106 are set when Init Response is received.
1108 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1109 but returns diagnostic set as well.
1111 New function yaz_strerror which is a portable wrapper for
1112 strerror/strerror_r/GetLastMessage.
1114 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1115 is returned for MARC. If type is "oai", then OAI MARC is returned.
1117 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1120 --- 1.9.2 2002/11/26
1122 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1124 Fix bad race conditions on SIGTERM and terminate gracefully in
1127 Move retrieval (data1) module to Zebra since nobody seems to be
1130 Add GRS-1 render for ZOOM using same format as yaz-client.
1132 --- 1.9.1 2002/10/05
1134 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1136 Fix broken ESpec handling in data1 module.
1138 SGML reader parses comments and makes them part of the data1 tree.
1140 Added several type casts so that YAZ compiles as C++ code.
1142 ZOOM didn't handle PDU encoding failures properly.
1144 Added more Bib-1 diagnostics (approved extensions).
1146 GNU configure: better check for iconv.
1148 More portable use of accept, getpeername. Check for socklen_t. Use
1149 int/size_t if socklen_t is not defined.
1153 PQF parser rejects bad queries - including those with extra
1154 characters in them. PQF parser used to silently ignore that.
1155 Cleaner API for PQF added, which allows you to get detailed
1156 error information for bad queries (see yaz/pquery.h).
1158 Fixed bug in ZOOM_record_get for type "database".
1160 Implemented mini iconv library supporting conversions between
1161 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1163 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1165 --- 1.8.9 2002/08/20
1167 Fixed ZOOM C record cache so that preferredRecordSyntax and
1168 elementSetName is used to check for already fetched records.
1170 --- 1.8.8 2002/08/02
1172 Added three members in bend_initrequest structure to facilitate
1173 character set negotiation.
1175 Fixed a bug in frontend server that could cause indefinite
1176 loops under rare conditions.
1178 Revised character set utilities (charneg.h) so that encoding
1179 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1181 For PQF, directive @term <type> sets term type for Scan/Search.
1182 Here <type> is general, string, numeric, null. The term type
1183 is inherited - just like @attr.
1185 New call odr_set_charset that sets character set conversion for
1186 international-strings on a ODR stream. Prototype is:
1187 int odr_set_charset(ODR o, const char *to, const char *from);
1188 The InternationalString is still represented as C string in YAZ
1189 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1190 won't). On the protocol level, you can use any encoding.
1192 Support for UNIX sockets in ZOOM.
1194 Solaris recv sometimes returns errno == ENOENT. It is treated as
1195 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1197 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1198 both client and server. Code by Morten Bøgeskov.
1200 --- 1.8.7 2002/05/22
1202 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1203 that they can be used directly from Visual Basic. You must recompile
1204 your windows APP if you're using ZOOM.
1206 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1207 Commands "lang" and "charset" sets language and character set respectively.
1208 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1209 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1211 Attributes from multiple CCL fields may be OR'ed rather than merged
1212 using directive "@field or". Fields are still merged by default -
1213 equivalent to "@field merge".
1215 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1218 Fixed bug in zget for parameter ExtendedServicesResponse.
1222 --- 1.8.6 2002/03/25
1224 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1226 Client displays USR.1:SearchResult-1 (hits per term).
1228 Additional Search Info for search in Generic Frontend Server.
1230 Fixed CCL parsing of "field=s".
1232 WIN32 installer - using the excellent NSIS software from nullsoft.
1234 Fixed CCL parsing of "field = - <number>".
1236 Added function yaz_marc_decode that decodes MARC for line mode
1237 display or XML (similar to that used by JZKit).
1239 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1240 Z39.50. But ISO/ILL was, however.
1242 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1243 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1245 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1246 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1248 --- 1.8.5 2002/02/03
1250 New YAZ client features: Command completion and new commands:
1251 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1252 Code provided by Jacob Poulsen.
1254 New call oid_trav, that visits all registered OIDs via callback.
1256 Function ZOOM_record_get now returns const char pointer rather than
1257 void pointer. It saves a lot of type casts.
1259 For YAZ client, command "auth" now allows you to set authentication
1260 in IdPass style. It is enabled when three tokens are given - order
1261 is user, group and password.
1263 Fix memory leaks in MARC record handling for ZOOM.
1265 New option for YAZ client, -k <kilobytes> that sets
1266 maximum record size. Similar to -k option for generic frontend
1267 server and yaz-ztest.
1269 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1271 Prefix query parser reports "fail" when bad attribute set is given.
1273 Fix in MARC decoder. Proximity logging. Fix for attribute set
1274 in scan handler for server. Patches by Shigeru Ishida.
1276 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1279 Configure option --with-openssl=<dir> now works when a directory is
1280 specified. Patch provided by Morten Bøgeskov.
1282 New option for YAZ client, -u <auth>, that sets authentication.
1284 ZOOM fix: error information was sometimes "missing", since error
1285 was cleared/reset too when it shouldn't.
1287 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1289 --- 1.8.4 2002/01/04
1291 Scan for ZOOM API. New object ZOOM_scanset. New functions
1292 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1293 ZOOM_scanset_destroy.
1295 New ZOOM function, ZOOM_connection_last_event, that returns type
1296 of last event (such as "receive data", "send data", "apdu received",
1299 New ZOOM option, schema, that specifies schema for retrieval.
1301 New CCL feature. Qualifiers can be aliases for one or more
1302 other qualifiers (if more than one is given, OR is used).
1304 ZOOM uses named result sets if target supports it.
1306 Two new YAZ client commands: . (dot, which sources a script of YAZ
1307 client commands), and ! (to execute shell command.). Implemented
1310 Working on Debian packages.
1312 --- 1.8.3 2001/11/19
1314 YAZ client enables named result sets only if target supports it.
1316 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1318 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1319 with key="host" to get same result.
1321 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1322 Function Z3950_resultset_record(s) returns references to records
1323 "owned" by resultset. To become owner use Z3950_record_clone.
1325 Function z_ext_record handles Extended Services. Thanks to
1328 --- 1.8.2 2001/11/12
1330 CCL Parser fix: ignore token comma when dealing with and-lists.
1332 Documentation updates for COMSTACK.
1334 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1335 Changed prototype Z3950_records. For some functions, int parameters
1336 were changed to size_t.
1338 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1341 New MARC decode/display function, marc_display_exl, which properly rejects
1342 non-ISO2709 records. YAZ client uses it.
1344 --- 1.8.1 2001/10/29
1346 Fix bug: local attribute set wasn't set correctly in PQF strings.
1350 * Old Z39.50 codecs no longer supported.
1352 Added ZOOM C binding. See http://zoom.z3950.org/
1354 Renamed states for COMSTACKs to avoid confusion with events.
1356 Implemented cs_look and proper cs_rcvconnect.
1358 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1360 Configure detects POSIX threads on OpenBSD.
1362 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1363 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1365 When error is returned from present handler, non-surrogate diagnostic
1366 is returned in present response (and fetch handler is no longer called).
1368 * Minor adjustments to pquery parser (PQF). Token characters may be
1369 escaped by using backslash (C-style).
1371 PQF parser allows string attribute values to be specified. For @attr,
1372 non-numeric characters after the equal-sign are treated as strings
1373 (e.g. @attr 9=title).
1375 CCL trunction character may be defined (@truncation in file)
1377 * function zget_ExtendedServicesRequest sets waitAction to
1378 waitIfPossible (was wait).
1380 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1383 CCL operator names may be set in field definition files (CCL_bibset).
1384 See ccl/bib1 for an example.
1386 Fixes in ASN.1 compiler for C++ compatibility.
1388 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1389 and "op_or" to avoid conflict with C++.
1391 Fixed problem with GNU readline detection on Redhat 7.0.
1393 Added step-size for Scan backend handler.
1395 Fixed bug that made the frontend server crash when no attribute
1396 set was specified for scan.
1398 Front-end server automatically switches to original working directory
1399 when installed as an NT service. Previously -w had to be specified to
1402 Added extended attributes for retrieval module (data1), so that data1
1403 records carry d1_readXML/SGML attributes. d1_read also supports
1404 null-data rules ( <tag/>)
1406 On UNIX when POSIX threads are available, a separate library libyazthread
1407 is created. Programmers should link with that library and the yaz library
1408 when using threads. The reason for the split was that some applications
1409 on Linux, such as Apache, doesn't work well when using shared objects that
1412 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1413 (or any frontend server) in SSL mode by specifying ssl: followed by
1414 address. Only tested on UNIX.
1416 Added feature for CCL module. Virtual structure s=al or s=ol generates
1417 and-list and or-list respectively instead of phrase search.
1421 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1422 log_mask_str. This was done to avoid name conflicts with other libraries
1423 (such as other PHP extensions).
1425 Added raw OID member for preferred record syntax (request_format_raw)
1426 and returned record syntax (output_format_raw) for backend fetch method.
1428 Config file yaz-config now accepts options so that it returns specific
1429 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1431 Shared library support for UNIX using GNU libtool.
1433 * Modified backend interface. Request/Response struct's replaced by
1434 one read/write C struct. For example bend_fetchrequest and
1435 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1436 Every handler - even search has to be registered in bend_init
1437 handler. This means that the YAZ library no longer refers to
1438 external functions and it makes it possible to make the whole
1439 thing a single DLL/SO.
1441 Added Segment handler for backend server.
1443 Added Zmbol/Zebra administrative functions to YAZ client.
1445 Threaded frontend server on UNIX (when POSIX Threads are available).
1446 Starting the server with option -T enables multi-threading.
1450 Added configure option --enable-comp/disable-comp to control use
1451 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1452 located in sub directory asn.
1454 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1455 in ${exec_prefix}/bin along with the other programs yaz-client and
1458 GNU automake used to maintain makefiles.
1460 Added several OID's.
1462 Changed retrieval module so that we can load records with no abstract
1463 syntax defined. Tagpaths in these records are fully composed of string
1466 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1470 On UNIX, the generated makefile now supports a proper 'make install'.
1471 The prefix can be set via GNU configure to set the install location
1472 (default is /usr/local).
1474 * YAZ programs client and ztest were renamed to yaz-client and
1475 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1476 locations, such as /usr/bin,/usr/local/bin,etc.
1478 * YAZ Header files were moved from include to include/yaz. YAZ Header
1479 files are referred to as include <yaz/log.h> rather than <log.h>.
1480 The YAZ include path (-I ..) is therefore the same as before. Programmers
1481 should update their #include statements or use -Ipath/include/yaz
1482 instead. The main motivation for doing this change is that YAZ header files
1483 can be installed in "standard" locations /usr/include,/usr/local/include
1484 without introducing conflicts, since ALL YAZ header files are stored
1485 in subdirectory yaz (under /usr/include for example).
1487 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1488 rather than project/workspace files. We switched because project files
1489 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1492 Changed name of logging function, logf, to yaz_log, to prevent name
1493 clash with some math-log functions. The YAZ header log.h defines logf
1494 to yaz_log (#define) so there should be no incompatibilities by this
1497 Added bend_start/bend_stop handlers for server. These handler are
1498 called on start/stop of server. For windows they are called whenever
1499 a service is started/stopped.
1501 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1502 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1503 in util/yc.tcl. The auto-generated C code structures are, in a few
1504 cases, incompatible with the old decoders. There are differences in the
1505 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1506 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1507 The preprocessor variable ASN_COMPILED is defined when the compiled
1508 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1509 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1510 wish to use the old encoders/decoders you can specify --disable-yc
1513 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1514 version so that it supports both new - and old version of DB Update
1516 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1517 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1518 change. The name parameter can be set to 0 in which no name is specified
1519 for the construction. The macros odr_implicit and odr_explicit sets name
1520 parameter to zero for the construction involved. New macros
1521 odr_implicit_tag and odr_explicit_tag are similar to the others,
1522 except that a name parameter is added. For programmers' that don't use
1523 ODR they probably only need to change the call to z_APDU and z_External.
1525 Added access control facility by interfacing the TCP wrapper library.
1526 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1527 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1528 name of the daemon and enables the access control as specified in
1529 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1531 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1532 den Dool <H.M.vdnDool@kub.nl>.
1534 Added reference ID parameter to most functions in server API - refer
1535 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1537 Changed name of ccl library to libccl.a (was ccl.a).
1539 Fixed bug in decoder for Explain (Category TargetInfo).
1541 Added support for GNU readline in client. Thanks to Jacob Poulsen
1542 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1544 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1545 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1546 IMPLEMENTATION! This change was made to the development version before
1547 the ZIG decided to retract the amendment. If any users MUST be
1548 compatible with the original Update definition, PLEASE CONTACT US, and
1549 we will include a separate definition corresponding to the old Update
1550 ES. Note that because of the change to the ASN.1 of the
1551 TaskPackageRecordStructure we cannot define a single structure that
1552 will support both versions.
1554 * Added const modifier to buffer parameter for some ODR/BER encoding
1555 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1556 completeWAIS, odr_dumpBER.
1558 Fixed bug in client.c which caused a crash when a scanResponse didn't
1559 contain positionOfTerm.
1561 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1562 * will cause an error in a client if a non-YAZ target sends both a
1563 * list of Scan entries and non-surrogate diagnostics.
1565 Retrieval module enhancements. Tag sets may be typed in the reference
1566 to it. From the .abs-file the "tagset" directive takes a third optional
1567 integer type for the tag set referenced. From a .tag-file the "include"
1568 directive takes a third optional type as well. The old "type" directive
1569 in the tag set itself is still recognized but acts as the default type
1572 Backend interface change. Individual Scan terms returned from bend_scan
1573 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1574 in include/backend.h.
1576 Retrieval module enhancements. Multiple tag sets and attribute sets may
1577 be specified in abstract syntax specs. Revised the error/warning for
1578 logging messages reported by the retrieval module when reading the
1581 Object Identifier system (oid_..) changed. The API is backwards
1582 compatible but the oid-routines now allocates new OID's when needed.
1583 Raw OID's may be specified in oid_getvalbyname.
1585 YAZ now uses GNU configure to generate Makefile(s).
1587 * Minor changes in some of the member names of DeleteResultSetRequest and
1588 DeleteResultSetResponse. See include/proto.h.
1590 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1591 and added member 'languages' in TargetInfo (which was missing).
1593 Changed the way attribute sets are handled in the retrieval
1594 module. These are now cached, just like the abstract syntaxes
1597 Changed YAZ so that it links with compiled ASN.1.
1599 Added Explain-schema definitions and mapping routines. The following
1600 Explain categories have been implemented: AttributeDetails,
1601 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1603 Fixed minor bug in Windows version of Server Library.
1605 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1607 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1609 Added EXTERNAL: UNIverse Resource Report (non-standard).
1611 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1612 ENUMERATED and SET OF.
1614 * Added 'const' to some of the char pointer arguments for the
1615 functions, data1_read_node, data1_getelementbytagname,
1616 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1619 Fixed bug in data1_insert_taggeddata - the last_child member of
1620 parent wasn't initialised.
1622 * Changed data1_read_record and data1_read_node so that the supplied
1623 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1624 doesn't refer to any parts of the "SGML"-buffer.
1626 Fixed bug in server library (Windows version of statserv_remove).
1628 * Changed code so that it compiles as C++. The type definition
1629 of Odr_fun which is a member of Odr_arm was changed. The result is,
1630 that an explicit typecast is needed for the fun pointer when
1631 using Odr_arm - as in:
1632 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1634 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1636 Implemented the new structured date and time definition as approved
1637 by the ZIG. Added schemaId element to the specificTag in Espec-1
1638 (also approved at the last ZIG). Thanks to RVDM.
1640 Added some Object identifiers (RVDM).
1642 Changed the Update Extended Service (RVDM).
1644 Added command "refid" to client which specifies referenceId for
1645 the following requests.
1647 Implemented extended service handling for server. See ztest.c
1648 for an example as well as backend.h. New handlers are registerd
1649 in the Init handler.
1651 * Changed interface for sort in server.
1653 Added new members to statserv_options_block. It allows a server
1654 to read options from another source than just the command line. Thanks
1655 to Charles Woodfield.
1657 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1658 renamed to zboolean. Some C++ compilers complained about the name.
1660 Minor changes to gils.abs. Added index 's' (sort) on title
1661 and date/time-last-modified.
1663 --- 1.4pl2 1998/1/30
1665 Fixed bug in server library regarding inetd mode (-i). This bug
1666 was introduced by release 1.4.
1668 --- 1.4pl1 1998/1/29
1670 Added sort facility in client and backend server interface.
1672 Fixed problem with dependencies in Makefile(s).
1674 Fixed bugs for encoders/decoders of extended services and
1677 Implemented sub-tree feature for schemas. Sub-trees are
1678 referenced in *.abs-files. See explain.abs for an example
1679 of the use of this feature.
1681 Modified bib1.att; local attributes for ANY didn't include
1682 ANY itself (only affects use of the retrieval module).
1684 Fixed bug in plain SGML reader in function data1_read_node:
1685 tags with prefix "var" was incorrectly interpreted as variants.
1687 Added feature "sub-schemas" to enable references to - and definitions
1688 of - group of elements.
1690 * Removed member parent from type data1_element (in data1.h).
1692 Implemented function odr_nullval() that returns the value of
1695 * Removed member num_children from data1_node (in data1.h).
1697 Made NT service interface part of the server library. The
1698 function statserv_main uses the NT service when required and
1699 calls the statserv_start / statserv_close routines.
1701 Routine zget_SearchRequest and zget_PresentRequest fills
1702 resultSetName/Id member with "default" instead of "Default".
1704 Fixed memory leak in server. Request queue member wasn't freed.
1706 Fixed nmem_exit so that memory is freed.
1710 Revised the CCL parser utility to be thread safe.
1712 Added function, oid_ent_to_oid, to replace the function
1713 oid_getoidbyent, which is not thread safe.
1715 * Added nmem_init and nmem_exit to initialize and release
1716 NMEM resources. Function nmem_init should be called once in the
1717 initial thread before NMEM/ODR is used. statserv.c and client.c
1718 have been changed accordingly. The change was necessary to make
1719 NMEM thread safe. The NMEM memory pool is shared amongst threads
1720 in a process. Unix-based applications will still work fine without
1723 Added NT Services interface for the the Z39.50 (statserv) Server.
1724 Refer to the ztest.c source on the usage.
1726 Windows 95/NT port using MSVC5.0. Project files are included in the
1729 * Defined new 'global' handle for the retrieval (data1) system. The
1730 new handled, data1_handle, describes the state of the data1 system.
1731 This handle is passed as first argument to virtually all
1732 data1 related routines. The functions data1_create and data1_destroy
1733 creates and destroys a data1 handle respectively.
1735 Added ODR encode stream member to all backend request structures
1736 init, search, scan etc. This stream should be used to allocate all
1737 memory used for the response when thread safe operation is needed.
1739 Changed the comstack utility, cs_addstr, to be thread safe. The
1740 returned hostname string returned by the function is now part the
1743 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1744 function. The cs_straddr takes a COMSTACK handle as argument, so this
1745 function must be used after cs_create and before bind/connect.
1746 This function is thread safe.
1748 Moved test server to 'ztest' directory - generic server code still
1749 in 'server' directory.
1751 Made prefix query (pquery.c) utility thread safe.
1753 Added new function modifier YAZ_EXPORT to 'export' public DLL
1754 functions when using windows (see include/yconfig.h).
1756 Added definitions to the OID database (util/oid.c) (RVDM).
1758 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1760 Added call to ccl_rpn_delete in client program.
1762 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1763 release of RPN structure.
1765 Added support for C++, headers uses extern "C" for public definitions.
1766 With input from RVDM.
1768 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1769 Thanks to Ronald van der Meer (RVDM).
1771 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1773 Added support for private extensions to the OID database
1774 (oid_setprivateoids()). Thanks to RVDM.
1776 Added optional, physical ANY (key replication)
1778 Fixed null-reference problem in GRS-1 output filter.
1780 Proximity operator added to Prefix Query Format (PQF).
1782 In test client command "base" accepts multiple databases.
1784 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1788 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1790 Smallish bug-fixes in the new encoders/decoders (explain).
1792 Bug fixed in DeleteRequest.
1794 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1796 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1798 Added SOIF syntax (using private OID for now) to retrieval module and client.
1800 Added Update extended service.
1802 Added SearchResult-1 additional info structure.
1804 Added optional CCL (ISO8777) interpreter as separate module. Available
1807 --- 1.2 1996/6/10 (1st anniversary release)
1809 Added Summary record syntax. Lightly tested.
1811 Added OPAC record syntax. Untested.
1813 Added ResourceReport service encoders/decoders. Untested.
1815 Fixed bug in z_Unit - wrong tagging on unitSystem.
1817 Fixed bug in the DiagRecs decoder.
1819 Added options for max PDU size and session timeout to frontend-server.
1821 Added documentation of query-language parsers and other supporting utilities.
1823 [frontend-server] Added Attribute set to the bend_scanrequest API.
1825 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1826 surrogate diagnostics were generated.
1828 [retrieval] Allow multiple local values for attribute.
1830 [retrieval] Allow multiple attributes per element in .abs files. index type.
1832 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1834 --- 1.1pl2 1996/4/10
1836 Minor changes, mostly specific to Zebra's requirements (retrieval)
1840 Repaired bug in frontend server when running multiple listening
1841 endpoints in dynamic mode.
1843 z_External() now won't break if a known, ASN.1 value comes encapsulated
1844 in an octet-string. The value will pass through unmodified in an Odr_oct.
1846 Added a bit of code to the demo client to decode & display
1847 ASN.1-structured records represented in the octet-aligned branch of
1848 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1850 Added z_ext_getentbyref() to the ASN module. Doc updated.
1852 * Completed the SCAN definition in the ASN module. This may break SCAN
1853 code based on older YAZ-versions at compile-time. The fix is easy -
1856 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1857 under the SCAN definition. Remember to initialize this, server-people.
1859 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1860 that this does not extend to ODR and ASN.
1862 Comstack allows insertion of established socket (primarily for
1863 inetd-operation of servers). Doc updated.
1865 Front-end server can now start from the inetd in TCP mode. Doc
1868 --- 1.0pl4 1996/1/24
1872 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1873 the rank and record number.
1875 Adjustments to the frontend server.
1877 Fixed diagnostic BER dumper. It ignored the file argument.
1881 Various changes to retrieval module.
1883 Changed the union discriminators of the protocol files from enums to
1884 ints paired with #defines.
1886 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1889 *Changed operator in the RPN structure to 'roperator', again to avoid a
1892 Fixed problems in Explain decoders/encoders.
1894 --- 1.0pl2 1995/12/6
1896 Memory bug in log module fixed.
1898 --- 1.0pl1 1995/12/5
1900 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1902 Bug in Explain DatabaseInfo module fixed.
1904 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1908 The shift to v1.0 signals that we now consider the *core* functionality
1909 of YAZ reasonably stable (the core being more or less equivalent to
1910 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1911 tested (Explain not at all - though that will happen soonish).
1913 Minor changes to code to support Windows port.
1915 Various minor changes after we're getting to use GRS-1 & co. more.
1917 Added Espec-1 format.
1919 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1920 of the protocol and it cannot be selected when encoding (maps into 'string'
1921 when decoding). Needed to talk to some servers.
1923 Demo client can request simple element set names.
1925 Added Diagnostic Format encoders/decoders.
1927 Added simple Close handling to frontend server (no hooks for resource
1928 reporting yet), and demonstration client.
1930 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1932 --- 1.0b3 1995/08/24
1934 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1935 handled incorrectly when records were requested in the searchResponse. This
1936 will only affect you if you use the frontend-server.
1938 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1939 Test-client will ask for and print GRS1. Ztest will return dummy records
1942 Added Explain encoders/decoders to the service-level API. Untested.
1944 Added Extended Services: Item Order encoders and decoders to the Service-
1945 level API. Untested. We could use a recent copy of the pertinent bits
1946 of the ILL protocol to add those bits.
1948 Added diagnostic format 1 encoders/decoders to the service-level API.
1951 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1952 odr_cons.c, which causes a more correct output.
1954 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1955 was always set to 0 when no records were requested in the searchRequest.
1957 * Added better external-handling. This shouldn't harm old code that
1958 *encodes* externals. It can break code that looks for a
1959 'single-ASN1-type' representation, since those types that are known
1960 are now decoded immediately. Look at the SUTRS sample code in
1961 seshigh.c and client.c. Documentation updated.
1963 Handling of structured records in bend_fetchresponse. Length -1 marks
1964 structured record, type is deduced from format field.
1966 --- 1.0b2 1995/06/27
1967 Fairly quick maintenance release to add SUTRS support.
1969 Fixed handling of SUTRS records in the demonstration client.
1971 * Added format field to the bend_fetchrequest and bend_fetchresponce
1972 structures of the backend API (frontend server). When the record is
1973 returned, the value of the format field is mapped to an OID. The
1974 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1975 of the record. The special value VAL_NONE in the bend_request means
1976 that no specific format was requested by the client. Documentation
1977 updated accordingly. Test server (ztest) will return a fixed dummy
1978 SUTRS record if your client requests SUTRS.
1980 Documentation updated accordingly.
1982 You can now set external libraries and RANLIB support in the top-level
1986 First public release.
