3 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
6 Fixed bug #779: Rotation of apdu.log fails.
8 Fixed for character set conversions:
9 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
10 Honor G1 set in MARC-8 decoding.
14 Fixed bug #775: char conversion does not handle Alternative UTF-8
17 Implemented function yaz_marc_read_line which parses MARC line format
18 records. There is a wealth of formats out there. So far, this function
19 reads line records produced by yaz_marc_write_line.
21 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
22 more generic and easier to remember(!) options: -i format and -o format
23 which specifies input format and output format respectively - where
24 format is one of "marc", "marcxml", "line", "marcxchange".
26 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
27 does not print anything except warnings for records.
29 For yaz-marcdump, added support for MARC split into files (-s) with a given
32 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
33 spec, at http://www.loc.gov/standards/sru/record-update/
34 This has changed the binary layout of the following structs:
35 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
36 bend_update_rr . Patch by Ko van der Sloot.
38 Added GFS utility function bend_assoc_is_alive which returns 1 if
39 association is still alive (client is connected); 0 otherwise (client
40 closed connection). This allows busy servers to stop working for
43 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
44 been a separate piece of software. This version of ziffy has been modified
45 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
47 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
49 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
50 Client code may now interrogate options such as "init_opt_sort" to
51 find out whether the server claims to support various options.
55 Added utilities yaz_{set,get}_esn to set/get element set name from
58 Removed the build of libyazthread.la. The libyaz.so is the threaded version
59 of YAZ and has been so since YAZ 2.1.10.
61 Implemented ZOOM_record_error which returns error information for
62 record (surrogate diagnostic).
66 Updates for SRU Update by Ko van der Sloot:
67 1. Changed name from "operation" to "action"
68 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
69 versions in the code, marked as 'backward compatible'.
70 3. Added diagnostics for SRU Update.
72 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
74 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
76 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
78 For GFS, fixed problem with SRU diagnostic 'First record position out of
79 range' being issued for 0 hits.
81 zoomtst10 part of Windows Build.
85 Implemented yaz_filepath_comp which splits a path into file path
86 components (required by Zebra 2.0.3+).
88 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
89 BSD inspired license until now so this should not have any real impact on
90 anybody. See http://www.opensource.org/licenses/bsd-license.php
92 Fixed bug #687: Missing log lines.
94 Fixed bug #678: CQL to PQF translation does not preserve double-quote
97 Fixed bug #689: SRU diagnostics to be added.
99 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
100 whether a connection is idle (no more work do do).
102 --- 2.1.34 2006/10/04
104 Change type of optval from long to int for invocation of setsockopt with
105 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
107 Added support for specifying the max log file size for the Generic
108 Frontend Server. The size is given with option -r.
110 --- 2.1.32 2006/09/21
112 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
114 --- 2.1.30 2006/09/17
116 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
119 Fixed bug in Generic Frontend Server that could cause a server to stop
120 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
122 For the generic frontend server, the maximum record size is used as maximum
123 size of incoming packages (SRU + Z39.50). The value until was previously
124 only used in Z39.50 Init negotiation and, later, in a session controlled
125 sizes of records returned. This is controlled using -k option. It can be
126 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
128 --- 2.1.28 2006/09/04
130 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
133 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
135 New option for yaz-marcdump -lpos=value which allows setting a portion
136 of MARC header to a certain value.
138 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
140 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
141 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
143 --- 2.1.26 2006/08/15
145 Fixed problem with SRU mode type (soap, get, post) for yaz-client
148 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
150 --- 2.1.24 2006/08/08
152 Fixed MARC ISO2709 encoding routines to deal with character set
155 Minor changes to GFS logging. Database included in search request log
158 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
159 cached/multiple records.
161 Shared libraries are built by default on Unix+configure.
163 Changed cql2pqf transformation to use a different evaluation order. The
164 new order is: always, relation, structure, position, truncation, index
165 and relationModifier. Old order was: always, relation, relationModifier,
166 structure, index, position, truncation. Note that the the latter ones
167 override former ones for identical attributes.. The new scheme means that
168 it is possible to override any existing attribute with a relationModifier.
169 And also that it is possible to override everything for the index rule
170 (except the ones listed in relationModifier). No order is perfect but this
171 one, we believe, covers more real cases.. The "always" should have been
172 called "default", since the attributes there can be overridden with all
175 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
176 compilation phase, but also for yaz-config --cflags output. This allows
177 us to have public headers with Libxml2 stuff in them . It should also,
178 eventually, make Libxml2 checks redundant in packages using YAZ, such
181 --- 2.1.22 2006/06/15
183 Changed SRU update structure bend_update_rr so that SRU diagnostics are
184 stored in uri, message and details.. Previously diagnostics were stored
185 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
186 compatibility.. but he's probably the only one affected, so.
188 Added support for CCL, compiled on the client side, in ZOOM-C. This
189 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
190 input; the resulting query objects can be used for for searching with
191 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
193 YAZ' configure searches for OpenSSL by default.
195 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
196 SL_CTX_use_certificate_file. See
197 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
198 for more info. Thanks to Ko van der Sloot.
200 --- 2.1.20 2006/06/02
202 Bug #600: SRU GET, POST support for yaz-client. Introduced
203 command 'sru' which selects method SOAP/GET/POST.
205 Allow missingValueAction to be specified for the sortspec string -
206 function yaz_sort_spec. By default, the missing value action is null.
207 Use ! to specify "abort". Use = followed by stringvalue to specify default
210 Ensured that Present-handler (if defined) is called in GFS before any call to
211 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
212 searchRetrieve requests.
214 Documentation for YAZ is now based on the Docbook XML/XSLT using
215 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
216 is no longer depending on jade/openjade or docbook-to-man scripts.
217 PDF is no longer part of the distribution - but can optionally be
218 made using DSSSL/jadetex or FOP.
220 Added retrieval handling support in Generic Frontend Server to support
221 conversion between MARC/XML as well as XSLTtransforms. See
222 etc/yazgfs.xml for an example.
224 Added Authentication support to Generic Frontend Server in SRU
225 mode. Authentication using HTTP Basic is supported, as is the use
226 of 'x-username' and 'x-password' parameters in the request itself.
228 Added support for a new character set MARC8s identical to MARC8 except
229 that it converts combined characters to single Unicode characters in the
230 Latin-1 range (when possible).
232 --- 2.1.18 2006/04/24
234 ASN.1 compiler 0.4: generates brief Doxygen file header for
235 generated .h/.c files.
237 Utility yaz_iconv now supports conversion to MARC-8.
239 New facilities for the MARC module. The reading - and writing of
240 content are separate methods for the yaz_marc_t handle. The following
241 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
242 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
243 format). Write functions have prefix yaz_marc_write_.. The existing
244 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
245 available. Removed support for OAI-MARC and simplexml (not the
246 simplexml from PHP5).
248 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
249 to be returned for this connection.
251 --- 2.1.16 2006/03/31
253 Allow multiple languages and charsets to be specified with
254 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
255 negcharset iso-8859-1,utf-8
257 Translation of proximity nodes from CQL into PQF now works.
259 Moved to automake 1.8, 1.9.
261 Added function yaz_log_set_handler which allows a log handler to be
262 installed. This handler will be called for all log messages. Output
263 to file is also produced; but that can be disabled by passing NULL
264 fname to yaz_log_init_file.
266 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
268 For SRW (including GFS), accept application/soap+xml as content-type
271 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
272 produces NO stylesheet reference even if a default stylesheet is specified
275 --- 2.1.14 2006/03/14
277 Updated Windows package to include yazd.dll + yazd.lib for the
278 Development component.
280 If the environment variable YAZ_LOG is set, then it is used as a
281 string indicating the default level of logging to use if not
282 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
283 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
284 used as before. So, for example, to omit warnings from YAZ logging,
287 cql_transform() now map structure and other attributes before indexes,
288 so that index-specific structures and other attributes can override
289 defaults. So now a combination of mapping specifications such as:
291 index.dc.date = 1=date-modified 4=5
292 does the right thing.
294 cql_transform() now also respects the "always" mapping specification,
295 which establishes an initial set of attributes to be used for all
296 terms except where overridden by more specific attributes associated
297 with the index, relation or modifier.
299 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
300 which mode to use; one of "post", "get" or "soap" (SRW, default).
302 Fixes for yaz_iconv routines: changed trie-based character set conversions
303 to use only non-negative values for bit fields due to Sun's C compiler not
304 supporting negative values.
306 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
307 sequences where not read correctly. Fix by Rustam Usmanov.
309 Updated win/makefile to use options, settings which makes things
310 compile with VS C 2005.
312 --- 2.1.12 2006/02/01
314 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
316 In ZOOM socket code, use select instead of poll on MacOSX.
318 ZOOM-C now support client-side compilation of CQL into RPN that is
319 sent to the server, enabling CQL to be used against all Z39.50
320 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
321 ZOOM_query object, and submit it using ZOOM_connection_search().
322 The CQL-to-RPN translation uses a configuration file, the name of
323 which must be specified in the Connection's "cqlfile" option.
325 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
326 function, which takes as its start-term parameter a ZOOM_query object
327 (which may have had either CQL or RPN set into it).
330 --- 2.1.10 2005/11/29
332 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
333 GFS to support this as well. Backend handler, bend_srw_update, does the
334 update work. Code contributed by Ko van der Sloot.
336 Allow retrieval of Search Result-1 information in ZOOM by the use of
337 options that are attached to a result set. ZOOM documentation updated
340 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
341 UTF-8 conversion. Patch by Raj Patel.
343 Added option -m to GFS to control formatting of timestamps in log file.
345 Added 'exit' as synonym for 'quit' in yaz-client
347 Added support for specifying SRW resultSetId + resultSetIdleTime in a
348 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
349 for the new members. Patch by Ko van der Sloot.
351 Added support for SRU POST. It is supported for content-type
352 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
354 Do not build the separate Multi-threaded (MT) library libyazthread.la.
355 Instead make the library libyaz.la multi-threaded. Threading as a whole
356 can still be disabled by configure option --disable-threads. Previosly,
357 with older GLIBCs there were problems with MT libs under Apache. This
358 has now been fixed a long time ago.
360 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
363 CQL module modified to be case insensitive for relations/indexes/operations.
365 Fixed bug in CQL transform code: incorrect value relationModifieder
368 Added 'show all' command for yaz-client which retrieves all results
371 Added new yaz-client, xmles, which takes a (private) OID and
372 a document to be sent as an extended service request.
374 Describe new yaz-client commands wait_response and set_auto_wait.
376 Increase TCP/IP listener backlog from 3 (which I am guessing was
377 copied from the SunOS manual entry way back when) so SOMAXCONN, so
378 that the socket will queue as many incoming connections as it's able
379 to handle ongoing connections. In other words, it will never now
380 refuse a connection that it would be able to handle merely because
381 it's not got around to accepting() enough of the pending connections
382 yet. This is the behaviour anyway under Linux, where the listen()
383 argument is ignored; but not under BSD and on systems such as
384 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
385 YAZ-based servers should now be uniform across operating systems in
388 yaz-marcdump uses 64-bit file access on some systems. This is enabled
389 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
390 This allows yaz-marcdump to read large MARC batches (>2 GB).
392 Modified all YAZ source files - except the source which is auto-generated
393 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
396 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
397 corresponding to the existing *_setl() function. These allow option
398 values containing arbitrary valuues.
400 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
401 ZOOM_resultset_sort() in new applications. Its behaviour is identical
402 except that it returns an indicator of whether or not the sort
403 criterion was accepted (0 for OK, -1 for invalid).
407 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
408 MARC output rather than returning "new" buffer.
410 yaz-client warns about unknown init options.
412 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
416 Added support for SRW sort in Generic Frontend Server. Patch
417 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
418 sortKeys - or NULL if none is provided.
420 Fixed bug #307: It was impossible to specify indefinite/no timeout
421 for ZOOM_event. Special timeout value -1 now means indefinite timeout
424 Added support for multiple languages and charsets to be specified in
425 ZOOM. Each charset/language is separated by a blank. If negotiation is
426 in effect in init-response, Option
427 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
428 Code based on patch by Vasiliy Osadchuk.
430 Fixed bug #306: infinite recursion that occurred when calling
431 yaz_log_level_init as the first call (before other log level or
434 Fixed bug in scan handling in front end server: if preferred-Position-In-
435 Response was non-present, a NULL pointer referece was performed.
439 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
440 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
441 now defined for all those error codes. So instead of putting 109 in
442 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
443 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
445 Modified the yaz-marcdump utility to skip garbage bytes between MARC
448 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
450 Program yaz-client now exits and produces an error message if multiple
451 Z39.50 servers are specified on the command line (none or one allowed
454 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
459 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
461 Fixed bug #272: Preserve spacing for CCL terms.
465 Added support for virtual hosts and multiple backend servers for
466 the YAZ frontend server. The configution is XML based and
467 support specificition of CQL to RPN mappings and explain information.
468 See section "Virtual Hosts" in the YAZ manual.
470 Extended OPAC display utility. OPAC display utility renders
471 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
472 to supplement yaz_marc_decode_wrbuf.
474 Fixed a bug in MARC decoder that could caused it to crash for some
475 invalid MARC records. More diagnostics and warnings where added in
476 XML output (warnings, etc are stored in comments).
478 --- 2.0.34 2005/02/08
480 Fixes for UNIX domain sockets. Bug #261.
482 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
484 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
485 Added yaz_marc_subfield_str which defines subfield lead string which is
486 used in YAZ_MARC_LINE format. Default string is blank+$. Added
487 yaz_marc_endline_str which defines end of fields string used in
488 YAZ_MARC_LINE format. Default string is newline.
490 Experimental support for MarcXChange. This format can be produced
491 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
492 http://www.bs.dk/standards/MarcXchange.xsd
494 Added yaz-client commands scansize that sets maximum number of
495 entries to be returned by scan.
497 --- 2.0.32 2005/01/11
499 Added support for SRW scan in yaz-client and Generic Frontend Server.
501 * Added whereInList member to SRW Scan Term.
503 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
505 Fixed NMEM system to return aligned blocks on the smallest boundaries
506 that are suitably aligned for all possible types on the particular
507 architecture YAZ is being built for.
509 --- 2.0.30 2005/01/04
511 Fixed numerious warnings that was issued with newer versions of GCC.
513 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
514 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
517 Make YAZ Generic Frontend Server slightly faster.
519 Enhance (and reduce) logging for Generic Frontend Server.
521 Revert YAZ log system so that it flushes every write operation
522 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
524 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
525 instead of LOG_, due to name clash with syslog(3). LOG_ are still
526 present. New applications should define YAZ_USE_NEW_LOG=1 - this
527 will effectively disable old definitions.
529 --- 2.0.28 2004/11/09
531 Added yaz_log_time_format which specifies log format using
534 Added yaz_log_module_level which returns mask for a module. Value
535 is non-zero mask a if module is enabled; zero if disabled.
537 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
538 in include/yaz/cql.h.
540 Fixed bug #176: Dont throw diagnostics on empty SRU args.
542 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
544 Fixed bug #172: RPM builds does not enable SSL.
546 Doxyfile.in part of dist. Doxyfile generated by configure.
548 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
549 are given and the corresponding component does not exist.
551 Extend CCL documentation in YAZ reference. Describe r=r.
553 --- 2.0.26 2004/10/01
555 Fixed MARC->MARCXML conversion to properly deal with
556 fields, subfields, indicators having non-ASCII characters.
558 Fixed MARC->MARCXML conversion so that ASCII control characters
559 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
562 Added YAZ GFS support for conversion from Z39.50 surrogate
563 diagnostics to SRW surrogate diagnostics.
565 Bug fix: YAZ GFS did not return schema in explainResponse.
567 --- 2.0.25 2004/09/30
569 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
570 now converts recordSchema to elementSetName as well as schema URI.
572 Fixed bug in COMSTACK that prevented HTTP request packages from being
575 --- 2.0.24 2004/09/29
577 Added CCL facility r=r "range" which is similar to r=o "ordered" but
578 does not require white-space before and after the dash in a range, e.g.
579 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
582 Fixed a few AC_TRY_LINK configure tests that did not operate properly
583 due to new GCC removing "redundant" code.
585 Added yaz-client commands scanpos and scanstep that sets preferred
586 position and step-size for scan.
588 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
590 Added CCL utility ccl_qual_buf which parses one or more CCL
591 spec lines in a buffer.
593 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
594 of name and value - ignoring empty lines and comments.
596 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
598 Added odr_get_element_path which returns current element path for an
599 ODR handle. This utility is useful in error handling or user-defined
602 Added ODR_PRINT utility odr_set_stream which is is a more generic
603 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
604 to a write function and pointer to close function. The close function - if
605 non-NULL - will be called during odr_destroy.
607 Fixed bug in CCL parser where truncation char was not removed from
608 right side when truncation=both was in effect.
610 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
613 --- 2.0.23 2004/08/11
615 Fix buffer overrun in CQL parser when dealing with proximity (%).
617 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
618 to UTF-8/UCS conversion is now only based on codetables.xml.
620 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
622 --- 2.0.22 2004/08/06
624 Add support for more "commit changes" in ZOOM (uses Extended Services).
626 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
629 Yet another small fix for configure of SSL.
631 --- 2.0.21 2004/05/14
633 Fix SSL libs for configure when --with-openssl=DIR is given.
635 --- 2.0.20 2004/05/10
637 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
639 SSL comstack now uses yaz.pem certificate file on server side
640 by default. Certificate filename can be configured by calling
641 comstack function cs_set_ssl_certificate_file before cs_bind is used.
643 Fix bug regarding multiple calls to ZOOM_connection_connect.
645 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
647 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
648 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
650 ZOOM now allows inspection of X509 peer certificate for verification.
651 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
653 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
654 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
655 as "modular" but it simplifies things.
657 Added cs_get_peer_certificate to that returns peer X509 PEM.
659 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
660 NULL if SSL is unavailable.
662 Documentation about MARC decoding tools.
664 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
666 --- 2.0.19 2004/03/30
668 Rename CHANGELOG to NEWS to follow GNU style packing.
670 Fix bug with missing initialization of member in init_diagnostics.
671 This bug affects threaded version of GFS server.
673 --- 2.0.18 2004/03/20
675 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
678 Ensure zlib.dll is packed with Windows install.
680 --- 2.0.17 2004/03/17
682 Fix encoding of xsd:string to use text instead of CDATA.
684 Fix endless loop in CQL parser with unbalanced ".
686 Use a more compact way to store MARC-8 conversion tables.
688 --- 2.0.16 2004/03/16 Debian only
690 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
693 Update CQL parser to use new CQL 1.1 modifiers for booleans and
698 --- 2.0.15 2004/03/01
700 Another fix for decoding of XML packed records.
702 --- 2.0.14 2004/02/25
704 Fixes for Chunked encoding. White space not ignored after length spec.
706 Update NS and use default NS for SRW diagnostic elements.
708 --- 2.0.13 2004/02/23
710 Implement ZOOM_resultset_cache_reset which resets record cache.
712 Implement ZOOM_resultset_sort which sorts a result set.
714 Implement chunked HTTP transfer.
716 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
718 --- 2.0.12 2004/02/16
720 Added member 'schema' to bend_explain_rr structure so that backend
721 can specify explain record identifier. Defaults to Zeerex 2.0.
723 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
725 --- 2.0.11 2004/02/16
727 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
730 Added init command for yaz-client which sends "extra" init request.
732 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
733 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
735 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
737 Make ZOOM error code for "invalid query".
739 Fixed compilation for SSL which wasn't properly enabled for all platforms.
741 --- 2.0.10 2004/02/05
743 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
746 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
748 Added option -p <file> to make Generic Frontend Server to write PID file.
750 Added option -D to put Generic Frontend Server in background on its own.
752 Make ZOOM C recognize option "password". If unset, "pass" is used
753 (for backwards compatibility).
755 Fixed a bug in Generic Frontend Server that could make it crash if a
756 client sets characterSetNegotation bit, but didn't pass negotiation stuff
759 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
760 Must be issued before open, in order to be in effect.
762 --- 2.0.9-6 2004/01/12 Debian/Windows
764 Make the SRU server more picky WRT unknown params, etc.
766 Bug fix: ZOOM scan response didn't return displayTerm - when present.
768 New YAZ client command, options, that sets Z39.50 options.
770 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
771 options from a string of tokens (one token for each option bit).
773 Update SRW diagnostic code messages.
775 --- 2.0.9-5 2004/01/07 Debian/Windows
777 Handle user defined stylesheet for SRW/SRU.
779 --- 2.0.9-4 2004/01/06 Debian/Windows
781 Fix bug in decoding of Content-Length.
783 --- 2.0.9-3 2004/01/06 Debian/Windows
785 Fix a bug with decoding of XML packed records.
787 --- 2.0.9-2 2004/01/05 Debian only
789 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
791 Fix bug in SRW/SRU diagnostics decoding.
795 Fixed bug in Generic Frontend Server which could drop records exceeding
796 preferred message size. Reported and fixed by Irina Dijour.
798 Fixed calculation of package size for structured records in Generic
799 Frontend Server. Reported and fixed by Irina Dijour.
801 Fixed namespace for SRW/SRU diagnostics.
803 Fixed SEGV in yaz-client that occured for HTTP connection errors.
807 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
808 this version is incompatible with version 1.0 and older YAZ SRW/SRU
811 CQL changes to reflect recent changes to the specification:
812 * Documentation talks about context sets instead of index sets.
813 * Documentation talks about indexes instead of qualifiers.
814 * The CQL-to-PQF transformer's configuration file now uses
815 "index.set.name = <attributes>" instead of the old form
816 "qualifier.set.name = <attributes>". (Both forms are still
817 understood but the latter is deprecated.)
818 * CQL terms with no explicit index specified are now interpreted as
819 cql.serverChoice instead of srw.serverChoice (which of course
820 behaves exactly the same.)
824 MARC conversion can now generate ISO2709 output in another
825 character set. yaz-marcdump uses this facility if you invoke it
828 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
829 functions from there can be used from C++.
833 Frontend server now transfers memory from decoded packages to stream
836 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
837 references to show up.
839 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
840 the ZOOM Abstract API. The older names for the same options are still
841 also supported for the benefit of old applications.
843 ZOOM-C supports "implementationId" and "implementationVersion" options
844 to go along with "implementationName". These allow the user code to
845 specify identification strings to be sent to servers.
846 Add OID for the new ExtLite attribute set.
848 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
849 as requested/supplid by Ere Maijala <ere@atp.fi>
851 For generic frontend server, reverse the order of
852 "toolkit-supplied / application-supplied" strings sent as implementationId,
853 Name and Version. Also, remove the spaces around the slash. This brings
854 the GFS in line with the behaviour of ZOOM-C on the client side.
856 Add function ZOOM_scanset_display_term.
858 yaz-client shows scan displayTerm if present.
860 Utility yaz-iconv is now installed by default along with the man page
863 Extend configure check for OpenSSL to use pkg-config where available (such
866 Incorporate patch by Morten Bogeskov which allows a Unix file socket
867 server to specify uid/gid/mask for socket using the format
868 unix:[user=uid,][group=gid,][umask=mask,]file=path
869 If file= is omitted the existing format is assumed, e.g.
871 in which case the mask is 0666 (rw for everybody).
873 Major restructure of YAZ source. All source in libyaz is in src directory.
874 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
875 util (utility programs such as ASN.1 compiler, yaz-marcdump).
877 Added man page for utility yaz-marcdump (used to be called marcdump).
878 yaz-marcdump is installed by 'make install'.
880 Fixed a memory leak in Generic Frontend Server that occurred when decoding
881 of incoming package failed.
883 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
885 Change prototype of odr_perror: add const to message string.
887 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
889 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
890 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
891 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
892 DNS lookup. There should not be any compatibility problems with this
893 assuming that blocking=1 or 0 is used.
895 Fix bad reference in UNIX comstack in function cs_addrstr.
897 Fix for compilation on AIX.
899 The generic front-end server (server/seshigh.c) now supports returning
900 Init diagnostics to the client in User-information-field, in
901 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
906 Allow any CQL relation (not just all,any,exact,scr).
908 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
909 that features the same UI.
911 Implemented command update0 in YAZ client which is equivalent to
912 update but uses old of Ext Update ASN.1.
914 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
915 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
916 Previously no OID was used for this info.
918 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
919 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
920 returns 'malformed search term' otherwise.
922 SortResponse member resultCount now set to NULL in sort handler of
925 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
928 Add three new utility functions for translating OIDs between various
929 formats -- symbolic name such as "Usmarc", minus-1-terminated int
930 arrays and dotted strings such as "1.2.840.10003.9.5.1":
931 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
932 char *oid_to_dotstring(const int *oid, char *oidbuf);
933 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
935 Reverted modifications for ES Update definition for z_IU0Update
936 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
937 is back to YAZ 2.0.2.
939 String value attributes for CCL parser.
941 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
942 which their FirstSearch server returns in Init responses, sometimes
943 carrying useful diagnostic information when Init fails. This has the
944 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
945 "z39.50/oclcui.asn", where its definition is somewhat different from
946 what OCLC document on their web-site, as required to interoperate with
949 Support for anonymous authentication in yaz-client. Use the command
952 * Fix the OID of the Index Data-local "admin" Extended Service from
953 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
954 the 1000, which indicates a locally-defined OID, was a mistake.
958 Fix CCL directive @case handling so that it affects string match for
959 both CCL keywords and qualifiers.
961 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
962 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
963 Decoder has been updated with ASN.1 changes as listed in
964 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
965 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
966 z_IUUpdate, remains unchanged.
968 ZOOM_record_get may now return a record in a specific character set.
969 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
970 "from" is the character set of record as returned by target. "to" is
971 the character set to be returned. If omitted, "to" is UTF-8.
973 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
975 New ODR utility, odr_getelement, which returns name of element for
976 which encoding/decoding failed.
978 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
979 in cases where a required element was omitted.
981 Bug fix: some MARC8 sequences were not converted.
983 New ZOOM option "step" which specifies number of records to be
984 retrieved in one chunk. Used in conjunction with "start" and "count".
986 SRW support for yaz-client. Use scheme http: to use it, e.g.
989 yaz-client no longer does (un)intelligent character set conversions
990 by default. Can be enabled with charset and marc_charset commands.
992 xmalloc trace fix for 64-bit systems such as DEC alpha.
994 Solaris 2.6 compile fix.
996 New function, cql_strerror() translates SRW error codes, as returned
997 by cql_transform_error(), into human-readable English strings. Used
998 in yaz-client diagnostics when appropriate.
1000 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1001 converts it into a type-1 query which is sent to the server. This
1002 makes CQL available for use with all Z-servers, as opposed to the tiny
1003 minority that can handle CQL queries themselves.
1005 --- 2.0.2 2003/04/28
1007 New Debian package layout similar to the Redhat Package layout.
1009 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1010 and search result respectively.
1012 --- 2.0.1 2003/04/25
1014 Redhat package is now several packages: libyaz (runtime libraries),
1015 libyaz-devel (development and documentation, and yaz (utility programs).
1016 Package spec file by Morten Bøgeskov.
1018 New member 'schema' in struct bend_fetch_rr which the name of requested
1019 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1020 handler MAY set this to reflect the schema of the returned record.
1022 New member 'display_term' in struct scan_entry. GFS now sets member entries
1023 and allocates scan entries to be filled by user scan handler. In previous
1024 version, entries member was allocated by the scan handler. That still works,
1025 but the GFS will ignore member display_term - assuming it was NOT set by
1026 the handler. The fact that the GFS now allocates the entries both allows
1027 for new members and makes a scan handler easier to write.
1029 Fix CQL lex buffer overflow.
1031 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1032 SRU default recordPacking is string.
1034 SRU protocol support for frontend server.
1036 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1038 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1040 Added scan for the ZOOM shell (zoomsh).
1044 * String Identifers for Schemas (Amendment 5).
1045 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1046 Old definition for schema
1047 Odr_oid *schema; /* OPT */
1052 Z_InternationalString *uri;
1053 #define Z_Schema_oid 1
1054 #define Z_Schema_uri 2
1057 * resultCount parameter to Sort Response (Amendment 1).
1058 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1060 Support for SRW 1.0 over HTTP. This is an optional feature and
1061 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1064 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1065 on the same port. SRW SearchRetrieveRequests are mapped
1066 to bend_init,bend_search,bend_fetch,bend_close.
1068 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1070 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1071 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1073 ZOOM connections are SRW based if schem http is used for hostname
1074 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1075 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1077 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1078 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1079 distance=n, order=true/false, relation=le, prox unit=word. If
1080 n is omitted, distance 1 is used.
1082 Fixed problem with C compiler include path in wrong order.
1084 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1085 on Solaris. Patch from Ko van der Sloot.
1087 New MARC decode API. All new functions operate on a yaz_marc_t
1088 handle. The most important new functions are: yaz_marc_create,
1089 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1090 decode and destroy respectively. Decoder can produce formats
1091 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1092 include/yaz/marcdisp.h.
1094 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1095 to UTF-8, UCS-32, wchar_t or Latin-1.
1097 * Prototypes for yaz_iconv_-functions moved to separate header
1098 include/yaz/yaz-iconv.h.
1100 Make a few private functions 'static' in unix.c. This prevents
1101 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1103 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1104 are set when Init Response is received.
1106 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1107 but returns diagnostic set as well.
1109 New function yaz_strerror which is a portable wrapper for
1110 strerror/strerror_r/GetLastMessage.
1112 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1113 is returned for MARC. If type is "oai", then OAI MARC is returned.
1115 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1118 --- 1.9.2 2002/11/26
1120 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1122 Fix bad race conditions on SIGTERM and terminate gracefully in
1125 Move retrieval (data1) module to Zebra since nobody seems to be
1128 Add GRS-1 render for ZOOM using same format as yaz-client.
1130 --- 1.9.1 2002/10/05
1132 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1134 Fix broken ESpec handling in data1 module.
1136 SGML reader parses comments and makes them part of the data1 tree.
1138 Added several type casts so that YAZ compiles as C++ code.
1140 ZOOM didn't handle PDU encoding failures properly.
1142 Added more Bib-1 diagnostics (approved extensions).
1144 GNU configure: better check for iconv.
1146 More portable use of accept, getpeername. Check for socklen_t. Use
1147 int/size_t if socklen_t is not defined.
1151 PQF parser rejects bad queries - including those with extra
1152 characters in them. PQF parser used to silently ignore that.
1153 Cleaner API for PQF added, which allows you to get detailed
1154 error information for bad queries (see yaz/pquery.h).
1156 Fixed bug in ZOOM_record_get for type "database".
1158 Implemented mini iconv library supporting conversions between
1159 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1161 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1163 --- 1.8.9 2002/08/20
1165 Fixed ZOOM C record cache so that preferredRecordSyntax and
1166 elementSetName is used to check for already fetched records.
1168 --- 1.8.8 2002/08/02
1170 Added three members in bend_initrequest structure to facilitate
1171 character set negotiation.
1173 Fixed a bug in frontend server that could cause indefinite
1174 loops under rare conditions.
1176 Revised character set utilities (charneg.h) so that encoding
1177 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1179 For PQF, directive @term <type> sets term type for Scan/Search.
1180 Here <type> is general, string, numeric, null. The term type
1181 is inherited - just like @attr.
1183 New call odr_set_charset that sets character set conversion for
1184 international-strings on a ODR stream. Prototype is:
1185 int odr_set_charset(ODR o, const char *to, const char *from);
1186 The InternationalString is still represented as C string in YAZ
1187 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1188 won't). On the protocol level, you can use any encoding.
1190 Support for UNIX sockets in ZOOM.
1192 Solaris recv sometimes returns errno == ENOENT. It is treated as
1193 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1195 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1196 both client and server. Code by Morten Bøgeskov.
1198 --- 1.8.7 2002/05/22
1200 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1201 that they can be used directly from Visual Basic. You must recompile
1202 your windows APP if you're using ZOOM.
1204 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1205 Commands "lang" and "charset" sets language and character set respectively.
1206 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1207 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1209 Attributes from multiple CCL fields may be OR'ed rather than merged
1210 using directive "@field or". Fields are still merged by default -
1211 equivalent to "@field merge".
1213 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1216 Fixed bug in zget for parameter ExtendedServicesResponse.
1220 --- 1.8.6 2002/03/25
1222 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1224 Client displays USR.1:SearchResult-1 (hits per term).
1226 Additional Search Info for search in Generic Frontend Server.
1228 Fixed CCL parsing of "field=s".
1230 WIN32 installer - using the excellent NSIS software from nullsoft.
1232 Fixed CCL parsing of "field = - <number>".
1234 Added function yaz_marc_decode that decodes MARC for line mode
1235 display or XML (similar to that used by JZKit).
1237 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1238 Z39.50. But ISO/ILL was, however.
1240 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1241 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1243 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1244 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1246 --- 1.8.5 2002/02/03
1248 New YAZ client features: Command completion and new commands:
1249 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1250 Code provided by Jacob Poulsen.
1252 New call oid_trav, that visits all registered OIDs via callback.
1254 Function ZOOM_record_get now returns const char pointer rather than
1255 void pointer. It saves a lot of type casts.
1257 For YAZ client, command "auth" now allows you to set authentication
1258 in IdPass style. It is enabled when three tokens are given - order
1259 is user, group and password.
1261 Fix memory leaks in MARC record handling for ZOOM.
1263 New option for YAZ client, -k <kilobytes> that sets
1264 maximum record size. Similar to -k option for generic frontend
1265 server and yaz-ztest.
1267 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1269 Prefix query parser reports "fail" when bad attribute set is given.
1271 Fix in MARC decoder. Proximity logging. Fix for attribute set
1272 in scan handler for server. Patches by Shigeru Ishida.
1274 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1277 Configure option --with-openssl=<dir> now works when a directory is
1278 specified. Patch provided by Morten Bøgeskov.
1280 New option for YAZ client, -u <auth>, that sets authentication.
1282 ZOOM fix: error information was sometimes "missing", since error
1283 was cleared/reset too when it shouldn't.
1285 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1287 --- 1.8.4 2002/01/04
1289 Scan for ZOOM API. New object ZOOM_scanset. New functions
1290 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1291 ZOOM_scanset_destroy.
1293 New ZOOM function, ZOOM_connection_last_event, that returns type
1294 of last event (such as "receive data", "send data", "apdu received",
1297 New ZOOM option, schema, that specifies schema for retrieval.
1299 New CCL feature. Qualifiers can be aliases for one or more
1300 other qualifiers (if more than one is given, OR is used).
1302 ZOOM uses named result sets if target supports it.
1304 Two new YAZ client commands: . (dot, which sources a script of YAZ
1305 client commands), and ! (to execute shell command.). Implemented
1308 Working on Debian packages.
1310 --- 1.8.3 2001/11/19
1312 YAZ client enables named result sets only if target supports it.
1314 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1316 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1317 with key="host" to get same result.
1319 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1320 Function Z3950_resultset_record(s) returns references to records
1321 "owned" by resultset. To become owner use Z3950_record_clone.
1323 Function z_ext_record handles Extended Services. Thanks to
1326 --- 1.8.2 2001/11/12
1328 CCL Parser fix: ignore token comma when dealing with and-lists.
1330 Documentation updates for COMSTACK.
1332 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1333 Changed prototype Z3950_records. For some functions, int parameters
1334 were changed to size_t.
1336 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1339 New MARC decode/display function, marc_display_exl, which properly rejects
1340 non-ISO2709 records. YAZ client uses it.
1342 --- 1.8.1 2001/10/29
1344 Fix bug: local attribute set wasn't set correctly in PQF strings.
1348 * Old Z39.50 codecs no longer supported.
1350 Added ZOOM C binding. See http://zoom.z3950.org/
1352 Renamed states for COMSTACKs to avoid confusion with events.
1354 Implemented cs_look and proper cs_rcvconnect.
1356 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1358 Configure detects POSIX threads on OpenBSD.
1360 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1361 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1363 When error is returned from present handler, non-surrogate diagnostic
1364 is returned in present response (and fetch handler is no longer called).
1366 * Minor adjustments to pquery parser (PQF). Token characters may be
1367 escaped by using backslash (C-style).
1369 PQF parser allows string attribute values to be specified. For @attr,
1370 non-numeric characters after the equal-sign are treated as strings
1371 (e.g. @attr 9=title).
1373 CCL trunction character may be defined (@truncation in file)
1375 * function zget_ExtendedServicesRequest sets waitAction to
1376 waitIfPossible (was wait).
1378 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1381 CCL operator names may be set in field definition files (CCL_bibset).
1382 See ccl/bib1 for an example.
1384 Fixes in ASN.1 compiler for C++ compatibility.
1386 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1387 and "op_or" to avoid conflict with C++.
1389 Fixed problem with GNU readline detection on Redhat 7.0.
1391 Added step-size for Scan backend handler.
1393 Fixed bug that made the frontend server crash when no attribute
1394 set was specified for scan.
1396 Front-end server automatically switches to original working directory
1397 when installed as an NT service. Previously -w had to be specified to
1400 Added extended attributes for retrieval module (data1), so that data1
1401 records carry d1_readXML/SGML attributes. d1_read also supports
1402 null-data rules ( <tag/>)
1404 On UNIX when POSIX threads are available, a separate library libyazthread
1405 is created. Programmers should link with that library and the yaz library
1406 when using threads. The reason for the split was that some applications
1407 on Linux, such as Apache, doesn't work well when using shared objects that
1410 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1411 (or any frontend server) in SSL mode by specifying ssl: followed by
1412 address. Only tested on UNIX.
1414 Added feature for CCL module. Virtual structure s=al or s=ol generates
1415 and-list and or-list respectively instead of phrase search.
1419 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1420 log_mask_str. This was done to avoid name conflicts with other libraries
1421 (such as other PHP extensions).
1423 Added raw OID member for preferred record syntax (request_format_raw)
1424 and returned record syntax (output_format_raw) for backend fetch method.
1426 Config file yaz-config now accepts options so that it returns specific
1427 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1429 Shared library support for UNIX using GNU libtool.
1431 * Modified backend interface. Request/Response struct's replaced by
1432 one read/write C struct. For example bend_fetchrequest and
1433 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1434 Every handler - even search has to be registered in bend_init
1435 handler. This means that the YAZ library no longer refers to
1436 external functions and it makes it possible to make the whole
1437 thing a single DLL/SO.
1439 Added Segment handler for backend server.
1441 Added Zmbol/Zebra administrative functions to YAZ client.
1443 Threaded frontend server on UNIX (when POSIX Threads are available).
1444 Starting the server with option -T enables multi-threading.
1448 Added configure option --enable-comp/disable-comp to control use
1449 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1450 located in sub directory asn.
1452 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1453 in ${exec_prefix}/bin along with the other programs yaz-client and
1456 GNU automake used to maintain makefiles.
1458 Added several OID's.
1460 Changed retrieval module so that we can load records with no abstract
1461 syntax defined. Tagpaths in these records are fully composed of string
1464 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1468 On UNIX, the generated makefile now supports a proper 'make install'.
1469 The prefix can be set via GNU configure to set the install location
1470 (default is /usr/local).
1472 * YAZ programs client and ztest were renamed to yaz-client and
1473 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1474 locations, such as /usr/bin,/usr/local/bin,etc.
1476 * YAZ Header files were moved from include to include/yaz. YAZ Header
1477 files are referred to as include <yaz/log.h> rather than <log.h>.
1478 The YAZ include path (-I ..) is therefore the same as before. Programmers
1479 should update their #include statements or use -Ipath/include/yaz
1480 instead. The main motivation for doing this change is that YAZ header files
1481 can be installed in "standard" locations /usr/include,/usr/local/include
1482 without introducing conflicts, since ALL YAZ header files are stored
1483 in subdirectory yaz (under /usr/include for example).
1485 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1486 rather than project/workspace files. We switched because project files
1487 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1490 Changed name of logging function, logf, to yaz_log, to prevent name
1491 clash with some math-log functions. The YAZ header log.h defines logf
1492 to yaz_log (#define) so there should be no incompatibilities by this
1495 Added bend_start/bend_stop handlers for server. These handler are
1496 called on start/stop of server. For windows they are called whenever
1497 a service is started/stopped.
1499 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1500 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1501 in util/yc.tcl. The auto-generated C code structures are, in a few
1502 cases, incompatible with the old decoders. There are differences in the
1503 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1504 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1505 The preprocessor variable ASN_COMPILED is defined when the compiled
1506 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1507 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1508 wish to use the old encoders/decoders you can specify --disable-yc
1511 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1512 version so that it supports both new - and old version of DB Update
1514 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1515 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1516 change. The name parameter can be set to 0 in which no name is specified
1517 for the construction. The macros odr_implicit and odr_explicit sets name
1518 parameter to zero for the construction involved. New macros
1519 odr_implicit_tag and odr_explicit_tag are similar to the others,
1520 except that a name parameter is added. For programmers' that don't use
1521 ODR they probably only need to change the call to z_APDU and z_External.
1523 Added access control facility by interfacing the TCP wrapper library.
1524 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1525 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1526 name of the daemon and enables the access control as specified in
1527 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1529 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1530 den Dool <H.M.vdnDool@kub.nl>.
1532 Added reference ID parameter to most functions in server API - refer
1533 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1535 Changed name of ccl library to libccl.a (was ccl.a).
1537 Fixed bug in decoder for Explain (Category TargetInfo).
1539 Added support for GNU readline in client. Thanks to Jacob Poulsen
1540 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1542 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1543 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1544 IMPLEMENTATION! This change was made to the development version before
1545 the ZIG decided to retract the amendment. If any users MUST be
1546 compatible with the original Update definition, PLEASE CONTACT US, and
1547 we will include a separate definition corresponding to the old Update
1548 ES. Note that because of the change to the ASN.1 of the
1549 TaskPackageRecordStructure we cannot define a single structure that
1550 will support both versions.
1552 * Added const modifier to buffer parameter for some ODR/BER encoding
1553 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1554 completeWAIS, odr_dumpBER.
1556 Fixed bug in client.c which caused a crash when a scanResponse didn't
1557 contain positionOfTerm.
1559 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1560 * will cause an error in a client if a non-YAZ target sends both a
1561 * list of Scan entries and non-surrogate diagnostics.
1563 Retrieval module enhancements. Tag sets may be typed in the reference
1564 to it. From the .abs-file the "tagset" directive takes a third optional
1565 integer type for the tag set referenced. From a .tag-file the "include"
1566 directive takes a third optional type as well. The old "type" directive
1567 in the tag set itself is still recognized but acts as the default type
1570 Backend interface change. Individual Scan terms returned from bend_scan
1571 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1572 in include/backend.h.
1574 Retrieval module enhancements. Multiple tag sets and attribute sets may
1575 be specified in abstract syntax specs. Revised the error/warning for
1576 logging messages reported by the retrieval module when reading the
1579 Object Identifier system (oid_..) changed. The API is backwards
1580 compatible but the oid-routines now allocates new OID's when needed.
1581 Raw OID's may be specified in oid_getvalbyname.
1583 YAZ now uses GNU configure to generate Makefile(s).
1585 * Minor changes in some of the member names of DeleteResultSetRequest and
1586 DeleteResultSetResponse. See include/proto.h.
1588 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1589 and added member 'languages' in TargetInfo (which was missing).
1591 Changed the way attribute sets are handled in the retrieval
1592 module. These are now cached, just like the abstract syntaxes
1595 Changed YAZ so that it links with compiled ASN.1.
1597 Added Explain-schema definitions and mapping routines. The following
1598 Explain categories have been implemented: AttributeDetails,
1599 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1601 Fixed minor bug in Windows version of Server Library.
1603 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1605 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1607 Added EXTERNAL: UNIverse Resource Report (non-standard).
1609 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1610 ENUMERATED and SET OF.
1612 * Added 'const' to some of the char pointer arguments for the
1613 functions, data1_read_node, data1_getelementbytagname,
1614 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1617 Fixed bug in data1_insert_taggeddata - the last_child member of
1618 parent wasn't initialised.
1620 * Changed data1_read_record and data1_read_node so that the supplied
1621 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1622 doesn't refer to any parts of the "SGML"-buffer.
1624 Fixed bug in server library (Windows version of statserv_remove).
1626 * Changed code so that it compiles as C++. The type definition
1627 of Odr_fun which is a member of Odr_arm was changed. The result is,
1628 that an explicit typecast is needed for the fun pointer when
1629 using Odr_arm - as in:
1630 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1632 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1634 Implemented the new structured date and time definition as approved
1635 by the ZIG. Added schemaId element to the specificTag in Espec-1
1636 (also approved at the last ZIG). Thanks to RVDM.
1638 Added some Object identifiers (RVDM).
1640 Changed the Update Extended Service (RVDM).
1642 Added command "refid" to client which specifies referenceId for
1643 the following requests.
1645 Implemented extended service handling for server. See ztest.c
1646 for an example as well as backend.h. New handlers are registerd
1647 in the Init handler.
1649 * Changed interface for sort in server.
1651 Added new members to statserv_options_block. It allows a server
1652 to read options from another source than just the command line. Thanks
1653 to Charles Woodfield.
1655 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1656 renamed to zboolean. Some C++ compilers complained about the name.
1658 Minor changes to gils.abs. Added index 's' (sort) on title
1659 and date/time-last-modified.
1661 --- 1.4pl2 1998/1/30
1663 Fixed bug in server library regarding inetd mode (-i). This bug
1664 was introduced by release 1.4.
1666 --- 1.4pl1 1998/1/29
1668 Added sort facility in client and backend server interface.
1670 Fixed problem with dependencies in Makefile(s).
1672 Fixed bugs for encoders/decoders of extended services and
1675 Implemented sub-tree feature for schemas. Sub-trees are
1676 referenced in *.abs-files. See explain.abs for an example
1677 of the use of this feature.
1679 Modified bib1.att; local attributes for ANY didn't include
1680 ANY itself (only affects use of the retrieval module).
1682 Fixed bug in plain SGML reader in function data1_read_node:
1683 tags with prefix "var" was incorrectly interpreted as variants.
1685 Added feature "sub-schemas" to enable references to - and definitions
1686 of - group of elements.
1688 * Removed member parent from type data1_element (in data1.h).
1690 Implemented function odr_nullval() that returns the value of
1693 * Removed member num_children from data1_node (in data1.h).
1695 Made NT service interface part of the server library. The
1696 function statserv_main uses the NT service when required and
1697 calls the statserv_start / statserv_close routines.
1699 Routine zget_SearchRequest and zget_PresentRequest fills
1700 resultSetName/Id member with "default" instead of "Default".
1702 Fixed memory leak in server. Request queue member wasn't freed.
1704 Fixed nmem_exit so that memory is freed.
1708 Revised the CCL parser utility to be thread safe.
1710 Added function, oid_ent_to_oid, to replace the function
1711 oid_getoidbyent, which is not thread safe.
1713 * Added nmem_init and nmem_exit to initialize and release
1714 NMEM resources. Function nmem_init should be called once in the
1715 initial thread before NMEM/ODR is used. statserv.c and client.c
1716 have been changed accordingly. The change was necessary to make
1717 NMEM thread safe. The NMEM memory pool is shared amongst threads
1718 in a process. Unix-based applications will still work fine without
1721 Added NT Services interface for the the Z39.50 (statserv) Server.
1722 Refer to the ztest.c source on the usage.
1724 Windows 95/NT port using MSVC5.0. Project files are included in the
1727 * Defined new 'global' handle for the retrieval (data1) system. The
1728 new handled, data1_handle, describes the state of the data1 system.
1729 This handle is passed as first argument to virtually all
1730 data1 related routines. The functions data1_create and data1_destroy
1731 creates and destroys a data1 handle respectively.
1733 Added ODR encode stream member to all backend request structures
1734 init, search, scan etc. This stream should be used to allocate all
1735 memory used for the response when thread safe operation is needed.
1737 Changed the comstack utility, cs_addstr, to be thread safe. The
1738 returned hostname string returned by the function is now part the
1741 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1742 function. The cs_straddr takes a COMSTACK handle as argument, so this
1743 function must be used after cs_create and before bind/connect.
1744 This function is thread safe.
1746 Moved test server to 'ztest' directory - generic server code still
1747 in 'server' directory.
1749 Made prefix query (pquery.c) utility thread safe.
1751 Added new function modifier YAZ_EXPORT to 'export' public DLL
1752 functions when using windows (see include/yconfig.h).
1754 Added definitions to the OID database (util/oid.c) (RVDM).
1756 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1758 Added call to ccl_rpn_delete in client program.
1760 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1761 release of RPN structure.
1763 Added support for C++, headers uses extern "C" for public definitions.
1764 With input from RVDM.
1766 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1767 Thanks to Ronald van der Meer (RVDM).
1769 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1771 Added support for private extensions to the OID database
1772 (oid_setprivateoids()). Thanks to RVDM.
1774 Added optional, physical ANY (key replication)
1776 Fixed null-reference problem in GRS-1 output filter.
1778 Proximity operator added to Prefix Query Format (PQF).
1780 In test client command "base" accepts multiple databases.
1782 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1786 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1788 Smallish bug-fixes in the new encoders/decoders (explain).
1790 Bug fixed in DeleteRequest.
1792 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1794 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1796 Added SOIF syntax (using private OID for now) to retrieval module and client.
1798 Added Update extended service.
1800 Added SearchResult-1 additional info structure.
1802 Added optional CCL (ISO8777) interpreter as separate module. Available
1805 --- 1.2 1996/6/10 (1st anniversary release)
1807 Added Summary record syntax. Lightly tested.
1809 Added OPAC record syntax. Untested.
1811 Added ResourceReport service encoders/decoders. Untested.
1813 Fixed bug in z_Unit - wrong tagging on unitSystem.
1815 Fixed bug in the DiagRecs decoder.
1817 Added options for max PDU size and session timeout to frontend-server.
1819 Added documentation of query-language parsers and other supporting utilities.
1821 [frontend-server] Added Attribute set to the bend_scanrequest API.
1823 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1824 surrogate diagnostics were generated.
1826 [retrieval] Allow multiple local values for attribute.
1828 [retrieval] Allow multiple attributes per element in .abs files. index type.
1830 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1832 --- 1.1pl2 1996/4/10
1834 Minor changes, mostly specific to Zebra's requirements (retrieval)
1838 Repaired bug in frontend server when running multiple listening
1839 endpoints in dynamic mode.
1841 z_External() now won't break if a known, ASN.1 value comes encapsulated
1842 in an octet-string. The value will pass through unmodified in an Odr_oct.
1844 Added a bit of code to the demo client to decode & display
1845 ASN.1-structured records represented in the octet-aligned branch of
1846 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1848 Added z_ext_getentbyref() to the ASN module. Doc updated.
1850 * Completed the SCAN definition in the ASN module. This may break SCAN
1851 code based on older YAZ-versions at compile-time. The fix is easy -
1854 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1855 under the SCAN definition. Remember to initialize this, server-people.
1857 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1858 that this does not extend to ODR and ASN.
1860 Comstack allows insertion of established socket (primarily for
1861 inetd-operation of servers). Doc updated.
1863 Front-end server can now start from the inetd in TCP mode. Doc
1866 --- 1.0pl4 1996/1/24
1870 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1871 the rank and record number.
1873 Adjustments to the frontend server.
1875 Fixed diagnostic BER dumper. It ignored the file argument.
1879 Various changes to retrieval module.
1881 Changed the union discriminators of the protocol files from enums to
1882 ints paired with #defines.
1884 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1887 *Changed operator in the RPN structure to 'roperator', again to avoid a
1890 Fixed problems in Explain decoders/encoders.
1892 --- 1.0pl2 1995/12/6
1894 Memory bug in log module fixed.
1896 --- 1.0pl1 1995/12/5
1898 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1900 Bug in Explain DatabaseInfo module fixed.
1902 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1906 The shift to v1.0 signals that we now consider the *core* functionality
1907 of YAZ reasonably stable (the core being more or less equivalent to
1908 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1909 tested (Explain not at all - though that will happen soonish).
1911 Minor changes to code to support Windows port.
1913 Various minor changes after we're getting to use GRS-1 & co. more.
1915 Added Espec-1 format.
1917 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1918 of the protocol and it cannot be selected when encoding (maps into 'string'
1919 when decoding). Needed to talk to some servers.
1921 Demo client can request simple element set names.
1923 Added Diagnostic Format encoders/decoders.
1925 Added simple Close handling to frontend server (no hooks for resource
1926 reporting yet), and demonstration client.
1928 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1930 --- 1.0b3 1995/08/24
1932 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1933 handled incorrectly when records were requested in the searchResponse. This
1934 will only affect you if you use the frontend-server.
1936 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1937 Test-client will ask for and print GRS1. Ztest will return dummy records
1940 Added Explain encoders/decoders to the service-level API. Untested.
1942 Added Extended Services: Item Order encoders and decoders to the Service-
1943 level API. Untested. We could use a recent copy of the pertinent bits
1944 of the ILL protocol to add those bits.
1946 Added diagnostic format 1 encoders/decoders to the service-level API.
1949 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1950 odr_cons.c, which causes a more correct output.
1952 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1953 was always set to 0 when no records were requested in the searchRequest.
1955 * Added better external-handling. This shouldn't harm old code that
1956 *encodes* externals. It can break code that looks for a
1957 'single-ASN1-type' representation, since those types that are known
1958 are now decoded immediately. Look at the SUTRS sample code in
1959 seshigh.c and client.c. Documentation updated.
1961 Handling of structured records in bend_fetchresponse. Length -1 marks
1962 structured record, type is deduced from format field.
1964 --- 1.0b2 1995/06/27
1965 Fairly quick maintenance release to add SUTRS support.
1967 Fixed handling of SUTRS records in the demonstration client.
1969 * Added format field to the bend_fetchrequest and bend_fetchresponce
1970 structures of the backend API (frontend server). When the record is
1971 returned, the value of the format field is mapped to an OID. The
1972 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1973 of the record. The special value VAL_NONE in the bend_request means
1974 that no specific format was requested by the client. Documentation
1975 updated accordingly. Test server (ztest) will return a fixed dummy
1976 SUTRS record if your client requests SUTRS.
1978 Documentation updated accordingly.
1980 You can now set external libraries and RANLIB support in the top-level
1984 First public release.
