1 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
6 Fixed bug #775: char conversion does not handle Alternative UTF-8
9 Implemented function yaz_marc_read_line which parses MARC line format
10 records. There is a wealth of formats out there. So far, this function
11 reads line records produced by yaz_marc_write_line.
13 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
14 more generic and easier to remember(!) options: -i format and -o format
15 which specifies input format and output format respectively - where
16 format is one of "marc", "marcxml", "line", "marcxchange".
18 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
19 does not print anything except warnings for records.
21 For yaz-marcdump, added support for MARC split into files (-s) with a given
24 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
25 spec, at http://www.loc.gov/standards/sru/record-update/
26 This has changed the binary layout of the following structs:
27 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
28 bend_update_rr . Patch by Ko van der Sloot.
30 Added GFS utility function bend_assoc_is_alive which returns 1 if
31 association is still alive (client is connected); 0 otherwise (client
32 closed connection). This allows busy servers to stop working for
35 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
36 been a separate piece of software. This version of ziffy has been modified
37 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
39 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
41 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
42 Client code may now interrogate options such as "init_opt_sort" to
43 find out whether the server claims to support various options.
47 Added utilities yaz_{set,get}_esn to set/get element set name from
50 Removed the build of libyazthread.la. The libyaz.so is the threaded version
51 of YAZ and has been so since YAZ 2.1.10.
53 Implemented ZOOM_record_error which returns error information for
54 record (surrogate diagnostic).
58 Updates for SRU Update by Ko van der Sloot:
59 1. Changed name from "operation" to "action"
60 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
61 versions in the code, marked as 'backward compatible'.
62 3. Added diagnostics for SRU Update.
64 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
66 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
68 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
70 For GFS, fixed problem with SRU diagnostic 'First record position out of
71 range' being issued for 0 hits.
73 zoomtst10 part of Windows Build.
77 Implemented yaz_filepath_comp which splits a path into file path
78 components (required by Zebra 2.0.3+).
80 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
81 BSD inspired license until now so this should not have any real impact on
82 anybody. See http://www.opensource.org/licenses/bsd-license.php
84 Fixed bug #687: Missing log lines.
86 Fixed bug #678: CQL to PQF translation does not preserve double-quote
89 Fixed bug #689: SRU diagnostics to be added.
91 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
92 whether a connection is idle (no more work do do).
96 Change type of optval from long to int for invocation of setsockopt with
97 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
99 Added support for specifying the max log file size for the Generic
100 Frontend Server. The size is given with option -r.
102 --- 2.1.32 2006/09/21
104 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
106 --- 2.1.30 2006/09/17
108 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
111 Fixed bug in Generic Frontend Server that could cause a server to stop
112 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
114 For the generic frontend server, the maximum record size is used as maximum
115 size of incoming packages (SRU + Z39.50). The value until was previously
116 only used in Z39.50 Init negotiation and, later, in a session controlled
117 sizes of records returned. This is controlled using -k option. It can be
118 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
120 --- 2.1.28 2006/09/04
122 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
125 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
127 New option for yaz-marcdump -lpos=value which allows setting a portion
128 of MARC header to a certain value.
130 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
132 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
133 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
135 --- 2.1.26 2006/08/15
137 Fixed problem with SRU mode type (soap, get, post) for yaz-client
140 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
142 --- 2.1.24 2006/08/08
144 Fixed MARC ISO2709 encoding routines to deal with character set
147 Minor changes to GFS logging. Database included in search request log
150 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
151 cached/multiple records.
153 Shared libraries are built by default on Unix+configure.
155 Changed cql2pqf transformation to use a different evaluation order. The
156 new order is: always, relation, structure, position, truncation, index
157 and relationModifier. Old order was: always, relation, relationModifier,
158 structure, index, position, truncation. Note that the the latter ones
159 override former ones for identical attributes.. The new scheme means that
160 it is possible to override any existing attribute with a relationModifier.
161 And also that it is possible to override everything for the index rule
162 (except the ones listed in relationModifier). No order is perfect but this
163 one, we believe, covers more real cases.. The "always" should have been
164 called "default", since the attributes there can be overridden with all
167 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
168 compilation phase, but also for yaz-config --cflags output. This allows
169 us to have public headers with Libxml2 stuff in them . It should also,
170 eventually, make Libxml2 checks redundant in packages using YAZ, such
173 --- 2.1.22 2006/06/15
175 Changed SRU update structure bend_update_rr so that SRU diagnostics are
176 stored in uri, message and details.. Previously diagnostics were stored
177 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
178 compatibility.. but he's probably the only one affected, so.
180 Added support for CCL, compiled on the client side, in ZOOM-C. This
181 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
182 input; the resulting query objects can be used for for searching with
183 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
185 YAZ' configure searches for OpenSSL by default.
187 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
188 SL_CTX_use_certificate_file. See
189 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
190 for more info. Thanks to Ko van der Sloot.
192 --- 2.1.20 2006/06/02
194 Bug #600: SRU GET, POST support for yaz-client. Introduced
195 command 'sru' which selects method SOAP/GET/POST.
197 Allow missingValueAction to be specified for the sortspec string -
198 function yaz_sort_spec. By default, the missing value action is null.
199 Use ! to specify "abort". Use = followed by stringvalue to specify default
202 Ensured that Present-handler (if defined) is called in GFS before any call to
203 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
204 searchRetrieve requests.
206 Documentation for YAZ is now based on the Docbook XML/XSLT using
207 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
208 is no longer depending on jade/openjade or docbook-to-man scripts.
209 PDF is no longer part of the distribution - but can optionally be
210 made using DSSSL/jadetex or FOP.
212 Added retrieval handling support in Generic Frontend Server to support
213 conversion between MARC/XML as well as XSLTtransforms. See
214 etc/yazgfs.xml for an example.
216 Added Authentication support to Generic Frontend Server in SRU
217 mode. Authentication using HTTP Basic is supported, as is the use
218 of 'x-username' and 'x-password' parameters in the request itself.
220 Added support for a new character set MARC8s identical to MARC8 except
221 that it converts combined characters to single Unicode characters in the
222 Latin-1 range (when possible).
224 --- 2.1.18 2006/04/24
226 ASN.1 compiler 0.4: generates brief Doxygen file header for
227 generated .h/.c files.
229 Utility yaz_iconv now supports conversion to MARC-8.
231 New facilities for the MARC module. The reading - and writing of
232 content are separate methods for the yaz_marc_t handle. The following
233 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
234 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
235 format). Write functions have prefix yaz_marc_write_.. The existing
236 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
237 available. Removed support for OAI-MARC and simplexml (not the
238 simplexml from PHP5).
240 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
241 to be returned for this connection.
243 --- 2.1.16 2006/03/31
245 Allow multiple languages and charsets to be specified with
246 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
247 negcharset iso-8859-1,utf-8
249 Translation of proximity nodes from CQL into PQF now works.
251 Moved to automake 1.8, 1.9.
253 Added function yaz_log_set_handler which allows a log handler to be
254 installed. This handler will be called for all log messages. Output
255 to file is also produced; but that can be disabled by passing NULL
256 fname to yaz_log_init_file.
258 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
260 For SRW (including GFS), accept application/soap+xml as content-type
263 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
264 produces NO stylesheet reference even if a default stylesheet is specified
267 --- 2.1.14 2006/03/14
269 Updated Windows package to include yazd.dll + yazd.lib for the
270 Development component.
272 If the environment variable YAZ_LOG is set, then it is used as a
273 string indicating the default level of logging to use if not
274 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
275 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
276 used as before. So, for example, to omit warnings from YAZ logging,
279 cql_transform() now map structure and other attributes before indexes,
280 so that index-specific structures and other attributes can override
281 defaults. So now a combination of mapping specifications such as:
283 index.dc.date = 1=date-modified 4=5
284 does the right thing.
286 cql_transform() now also respects the "always" mapping specification,
287 which establishes an initial set of attributes to be used for all
288 terms except where overridden by more specific attributes associated
289 with the index, relation or modifier.
291 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
292 which mode to use; one of "post", "get" or "soap" (SRW, default).
294 Fixes for yaz_iconv routines: changed trie-based character set conversions
295 to use only non-negative values for bit fields due to Sun's C compiler not
296 supporting negative values.
298 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
299 sequences where not read correctly. Fix by Rustam Usmanov.
301 Updated win/makefile to use options, settings which makes things
302 compile with VS C 2005.
304 --- 2.1.12 2006/02/01
306 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
308 In ZOOM socket code, use select instead of poll on MacOSX.
310 ZOOM-C now support client-side compilation of CQL into RPN that is
311 sent to the server, enabling CQL to be used against all Z39.50
312 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
313 ZOOM_query object, and submit it using ZOOM_connection_search().
314 The CQL-to-RPN translation uses a configuration file, the name of
315 which must be specified in the Connection's "cqlfile" option.
317 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
318 function, which takes as its start-term parameter a ZOOM_query object
319 (which may have had either CQL or RPN set into it).
322 --- 2.1.10 2005/11/29
324 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
325 GFS to support this as well. Backend handler, bend_srw_update, does the
326 update work. Code contributed by Ko van der Sloot.
328 Allow retrieval of Search Result-1 information in ZOOM by the use of
329 options that are attached to a result set. ZOOM documentation updated
332 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
333 UTF-8 conversion. Patch by Raj Patel.
335 Added option -m to GFS to control formatting of timestamps in log file.
337 Added 'exit' as synonym for 'quit' in yaz-client
339 Added support for specifying SRW resultSetId + resultSetIdleTime in a
340 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
341 for the new members. Patch by Ko van der Sloot.
343 Added support for SRU POST. It is supported for content-type
344 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
346 Do not build the separate Multi-threaded (MT) library libyazthread.la.
347 Instead make the library libyaz.la multi-threaded. Threading as a whole
348 can still be disabled by configure option --disable-threads. Previosly,
349 with older GLIBCs there were problems with MT libs under Apache. This
350 has now been fixed a long time ago.
352 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
355 CQL module modified to be case insensitive for relations/indexes/operations.
357 Fixed bug in CQL transform code: incorrect value relationModifieder
360 Added 'show all' command for yaz-client which retrieves all results
363 Added new yaz-client, xmles, which takes a (private) OID and
364 a document to be sent as an extended service request.
366 Describe new yaz-client commands wait_response and set_auto_wait.
368 Increase TCP/IP listener backlog from 3 (which I am guessing was
369 copied from the SunOS manual entry way back when) so SOMAXCONN, so
370 that the socket will queue as many incoming connections as it's able
371 to handle ongoing connections. In other words, it will never now
372 refuse a connection that it would be able to handle merely because
373 it's not got around to accepting() enough of the pending connections
374 yet. This is the behaviour anyway under Linux, where the listen()
375 argument is ignored; but not under BSD and on systems such as
376 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
377 YAZ-based servers should now be uniform across operating systems in
380 yaz-marcdump uses 64-bit file access on some systems. This is enabled
381 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
382 This allows yaz-marcdump to read large MARC batches (>2 GB).
384 Modified all YAZ source files - except the source which is auto-generated
385 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
388 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
389 corresponding to the existing *_setl() function. These allow option
390 values containing arbitrary valuues.
392 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
393 ZOOM_resultset_sort() in new applications. Its behaviour is identical
394 except that it returns an indicator of whether or not the sort
395 criterion was accepted (0 for OK, -1 for invalid).
399 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
400 MARC output rather than returning "new" buffer.
402 yaz-client warns about unknown init options.
404 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
408 Added support for SRW sort in Generic Frontend Server. Patch
409 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
410 sortKeys - or NULL if none is provided.
412 Fixed bug #307: It was impossible to specify indefinite/no timeout
413 for ZOOM_event. Special timeout value -1 now means indefinite timeout
416 Added support for multiple languages and charsets to be specified in
417 ZOOM. Each charset/language is separated by a blank. If negotiation is
418 in effect in init-response, Option
419 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
420 Code based on patch by Vasiliy Osadchuk.
422 Fixed bug #306: infinite recursion that occurred when calling
423 yaz_log_level_init as the first call (before other log level or
426 Fixed bug in scan handling in front end server: if preferred-Position-In-
427 Response was non-present, a NULL pointer referece was performed.
431 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
432 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
433 now defined for all those error codes. So instead of putting 109 in
434 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
435 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
437 Modified the yaz-marcdump utility to skip garbage bytes between MARC
440 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
442 Program yaz-client now exits and produces an error message if multiple
443 Z39.50 servers are specified on the command line (none or one allowed
446 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
451 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
453 Fixed bug #272: Preserve spacing for CCL terms.
457 Added support for virtual hosts and multiple backend servers for
458 the YAZ frontend server. The configution is XML based and
459 support specificition of CQL to RPN mappings and explain information.
460 See section "Virtual Hosts" in the YAZ manual.
462 Extended OPAC display utility. OPAC display utility renders
463 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
464 to supplement yaz_marc_decode_wrbuf.
466 Fixed a bug in MARC decoder that could caused it to crash for some
467 invalid MARC records. More diagnostics and warnings where added in
468 XML output (warnings, etc are stored in comments).
470 --- 2.0.34 2005/02/08
472 Fixes for UNIX domain sockets. Bug #261.
474 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
476 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
477 Added yaz_marc_subfield_str which defines subfield lead string which is
478 used in YAZ_MARC_LINE format. Default string is blank+$. Added
479 yaz_marc_endline_str which defines end of fields string used in
480 YAZ_MARC_LINE format. Default string is newline.
482 Experimental support for MarcXChange. This format can be produced
483 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
484 http://www.bs.dk/standards/MarcXchange.xsd
486 Added yaz-client commands scansize that sets maximum number of
487 entries to be returned by scan.
489 --- 2.0.32 2005/01/11
491 Added support for SRW scan in yaz-client and Generic Frontend Server.
493 * Added whereInList member to SRW Scan Term.
495 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
497 Fixed NMEM system to return aligned blocks on the smallest boundaries
498 that are suitably aligned for all possible types on the particular
499 architecture YAZ is being built for.
501 --- 2.0.30 2005/01/04
503 Fixed numerious warnings that was issued with newer versions of GCC.
505 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
506 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
509 Make YAZ Generic Frontend Server slightly faster.
511 Enhance (and reduce) logging for Generic Frontend Server.
513 Revert YAZ log system so that it flushes every write operation
514 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
516 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
517 instead of LOG_, due to name clash with syslog(3). LOG_ are still
518 present. New applications should define YAZ_USE_NEW_LOG=1 - this
519 will effectively disable old definitions.
521 --- 2.0.28 2004/11/09
523 Added yaz_log_time_format which specifies log format using
526 Added yaz_log_module_level which returns mask for a module. Value
527 is non-zero mask a if module is enabled; zero if disabled.
529 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
530 in include/yaz/cql.h.
532 Fixed bug #176: Dont throw diagnostics on empty SRU args.
534 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
536 Fixed bug #172: RPM builds does not enable SSL.
538 Doxyfile.in part of dist. Doxyfile generated by configure.
540 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
541 are given and the corresponding component does not exist.
543 Extend CCL documentation in YAZ reference. Describe r=r.
545 --- 2.0.26 2004/10/01
547 Fixed MARC->MARCXML conversion to properly deal with
548 fields, subfields, indicators having non-ASCII characters.
550 Fixed MARC->MARCXML conversion so that ASCII control characters
551 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
554 Added YAZ GFS support for conversion from Z39.50 surrogate
555 diagnostics to SRW surrogate diagnostics.
557 Bug fix: YAZ GFS did not return schema in explainResponse.
559 --- 2.0.25 2004/09/30
561 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
562 now converts recordSchema to elementSetName as well as schema URI.
564 Fixed bug in COMSTACK that prevented HTTP request packages from being
567 --- 2.0.24 2004/09/29
569 Added CCL facility r=r "range" which is similar to r=o "ordered" but
570 does not require white-space before and after the dash in a range, e.g.
571 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
574 Fixed a few AC_TRY_LINK configure tests that did not operate properly
575 due to new GCC removing "redundant" code.
577 Added yaz-client commands scanpos and scanstep that sets preferred
578 position and step-size for scan.
580 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
582 Added CCL utility ccl_qual_buf which parses one or more CCL
583 spec lines in a buffer.
585 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
586 of name and value - ignoring empty lines and comments.
588 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
590 Added odr_get_element_path which returns current element path for an
591 ODR handle. This utility is useful in error handling or user-defined
594 Added ODR_PRINT utility odr_set_stream which is is a more generic
595 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
596 to a write function and pointer to close function. The close function - if
597 non-NULL - will be called during odr_destroy.
599 Fixed bug in CCL parser where truncation char was not removed from
600 right side when truncation=both was in effect.
602 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
605 --- 2.0.23 2004/08/11
607 Fix buffer overrun in CQL parser when dealing with proximity (%).
609 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
610 to UTF-8/UCS conversion is now only based on codetables.xml.
612 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
614 --- 2.0.22 2004/08/06
616 Add support for more "commit changes" in ZOOM (uses Extended Services).
618 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
621 Yet another small fix for configure of SSL.
623 --- 2.0.21 2004/05/14
625 Fix SSL libs for configure when --with-openssl=DIR is given.
627 --- 2.0.20 2004/05/10
629 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
631 SSL comstack now uses yaz.pem certificate file on server side
632 by default. Certificate filename can be configured by calling
633 comstack function cs_set_ssl_certificate_file before cs_bind is used.
635 Fix bug regarding multiple calls to ZOOM_connection_connect.
637 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
639 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
640 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
642 ZOOM now allows inspection of X509 peer certificate for verification.
643 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
645 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
646 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
647 as "modular" but it simplifies things.
649 Added cs_get_peer_certificate to that returns peer X509 PEM.
651 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
652 NULL if SSL is unavailable.
654 Documentation about MARC decoding tools.
656 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
658 --- 2.0.19 2004/03/30
660 Rename CHANGELOG to NEWS to follow GNU style packing.
662 Fix bug with missing initialization of member in init_diagnostics.
663 This bug affects threaded version of GFS server.
665 --- 2.0.18 2004/03/20
667 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
670 Ensure zlib.dll is packed with Windows install.
672 --- 2.0.17 2004/03/17
674 Fix encoding of xsd:string to use text instead of CDATA.
676 Fix endless loop in CQL parser with unbalanced ".
678 Use a more compact way to store MARC-8 conversion tables.
680 --- 2.0.16 2004/03/16 Debian only
682 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
685 Update CQL parser to use new CQL 1.1 modifiers for booleans and
690 --- 2.0.15 2004/03/01
692 Another fix for decoding of XML packed records.
694 --- 2.0.14 2004/02/25
696 Fixes for Chunked encoding. White space not ignored after length spec.
698 Update NS and use default NS for SRW diagnostic elements.
700 --- 2.0.13 2004/02/23
702 Implement ZOOM_resultset_cache_reset which resets record cache.
704 Implement ZOOM_resultset_sort which sorts a result set.
706 Implement chunked HTTP transfer.
708 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
710 --- 2.0.12 2004/02/16
712 Added member 'schema' to bend_explain_rr structure so that backend
713 can specify explain record identifier. Defaults to Zeerex 2.0.
715 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
717 --- 2.0.11 2004/02/16
719 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
722 Added init command for yaz-client which sends "extra" init request.
724 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
725 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
727 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
729 Make ZOOM error code for "invalid query".
731 Fixed compilation for SSL which wasn't properly enabled for all platforms.
733 --- 2.0.10 2004/02/05
735 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
738 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
740 Added option -p <file> to make Generic Frontend Server to write PID file.
742 Added option -D to put Generic Frontend Server in background on its own.
744 Make ZOOM C recognize option "password". If unset, "pass" is used
745 (for backwards compatibility).
747 Fixed a bug in Generic Frontend Server that could make it crash if a
748 client sets characterSetNegotation bit, but didn't pass negotiation stuff
751 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
752 Must be issued before open, in order to be in effect.
754 --- 2.0.9-6 2004/01/12 Debian/Windows
756 Make the SRU server more picky WRT unknown params, etc.
758 Bug fix: ZOOM scan response didn't return displayTerm - when present.
760 New YAZ client command, options, that sets Z39.50 options.
762 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
763 options from a string of tokens (one token for each option bit).
765 Update SRW diagnostic code messages.
767 --- 2.0.9-5 2004/01/07 Debian/Windows
769 Handle user defined stylesheet for SRW/SRU.
771 --- 2.0.9-4 2004/01/06 Debian/Windows
773 Fix bug in decoding of Content-Length.
775 --- 2.0.9-3 2004/01/06 Debian/Windows
777 Fix a bug with decoding of XML packed records.
779 --- 2.0.9-2 2004/01/05 Debian only
781 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
783 Fix bug in SRW/SRU diagnostics decoding.
787 Fixed bug in Generic Frontend Server which could drop records exceeding
788 preferred message size. Reported and fixed by Irina Dijour.
790 Fixed calculation of package size for structured records in Generic
791 Frontend Server. Reported and fixed by Irina Dijour.
793 Fixed namespace for SRW/SRU diagnostics.
795 Fixed SEGV in yaz-client that occured for HTTP connection errors.
799 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
800 this version is incompatible with version 1.0 and older YAZ SRW/SRU
803 CQL changes to reflect recent changes to the specification:
804 * Documentation talks about context sets instead of index sets.
805 * Documentation talks about indexes instead of qualifiers.
806 * The CQL-to-PQF transformer's configuration file now uses
807 "index.set.name = <attributes>" instead of the old form
808 "qualifier.set.name = <attributes>". (Both forms are still
809 understood but the latter is deprecated.)
810 * CQL terms with no explicit index specified are now interpreted as
811 cql.serverChoice instead of srw.serverChoice (which of course
812 behaves exactly the same.)
816 MARC conversion can now generate ISO2709 output in another
817 character set. yaz-marcdump uses this facility if you invoke it
820 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
821 functions from there can be used from C++.
825 Frontend server now transfers memory from decoded packages to stream
828 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
829 references to show up.
831 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
832 the ZOOM Abstract API. The older names for the same options are still
833 also supported for the benefit of old applications.
835 ZOOM-C supports "implementationId" and "implementationVersion" options
836 to go along with "implementationName". These allow the user code to
837 specify identification strings to be sent to servers.
838 Add OID for the new ExtLite attribute set.
840 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
841 as requested/supplid by Ere Maijala <ere@atp.fi>
843 For generic frontend server, reverse the order of
844 "toolkit-supplied / application-supplied" strings sent as implementationId,
845 Name and Version. Also, remove the spaces around the slash. This brings
846 the GFS in line with the behaviour of ZOOM-C on the client side.
848 Add function ZOOM_scanset_display_term.
850 yaz-client shows scan displayTerm if present.
852 Utility yaz-iconv is now installed by default along with the man page
855 Extend configure check for OpenSSL to use pkg-config where available (such
858 Incorporate patch by Morten Bogeskov which allows a Unix file socket
859 server to specify uid/gid/mask for socket using the format
860 unix:[user=uid,][group=gid,][umask=mask,]file=path
861 If file= is omitted the existing format is assumed, e.g.
863 in which case the mask is 0666 (rw for everybody).
865 Major restructure of YAZ source. All source in libyaz is in src directory.
866 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
867 util (utility programs such as ASN.1 compiler, yaz-marcdump).
869 Added man page for utility yaz-marcdump (used to be called marcdump).
870 yaz-marcdump is installed by 'make install'.
872 Fixed a memory leak in Generic Frontend Server that occurred when decoding
873 of incoming package failed.
875 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
877 Change prototype of odr_perror: add const to message string.
879 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
881 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
882 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
883 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
884 DNS lookup. There should not be any compatibility problems with this
885 assuming that blocking=1 or 0 is used.
887 Fix bad reference in UNIX comstack in function cs_addrstr.
889 Fix for compilation on AIX.
891 The generic front-end server (server/seshigh.c) now supports returning
892 Init diagnostics to the client in User-information-field, in
893 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
898 Allow any CQL relation (not just all,any,exact,scr).
900 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
901 that features the same UI.
903 Implemented command update0 in YAZ client which is equivalent to
904 update but uses old of Ext Update ASN.1.
906 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
907 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
908 Previously no OID was used for this info.
910 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
911 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
912 returns 'malformed search term' otherwise.
914 SortResponse member resultCount now set to NULL in sort handler of
917 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
920 Add three new utility functions for translating OIDs between various
921 formats -- symbolic name such as "Usmarc", minus-1-terminated int
922 arrays and dotted strings such as "1.2.840.10003.9.5.1":
923 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
924 char *oid_to_dotstring(const int *oid, char *oidbuf);
925 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
927 Reverted modifications for ES Update definition for z_IU0Update
928 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
929 is back to YAZ 2.0.2.
931 String value attributes for CCL parser.
933 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
934 which their FirstSearch server returns in Init responses, sometimes
935 carrying useful diagnostic information when Init fails. This has the
936 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
937 "z39.50/oclcui.asn", where its definition is somewhat different from
938 what OCLC document on their web-site, as required to interoperate with
941 Support for anonymous authentication in yaz-client. Use the command
944 * Fix the OID of the Index Data-local "admin" Extended Service from
945 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
946 the 1000, which indicates a locally-defined OID, was a mistake.
950 Fix CCL directive @case handling so that it affects string match for
951 both CCL keywords and qualifiers.
953 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
954 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
955 Decoder has been updated with ASN.1 changes as listed in
956 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
957 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
958 z_IUUpdate, remains unchanged.
960 ZOOM_record_get may now return a record in a specific character set.
961 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
962 "from" is the character set of record as returned by target. "to" is
963 the character set to be returned. If omitted, "to" is UTF-8.
965 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
967 New ODR utility, odr_getelement, which returns name of element for
968 which encoding/decoding failed.
970 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
971 in cases where a required element was omitted.
973 Bug fix: some MARC8 sequences were not converted.
975 New ZOOM option "step" which specifies number of records to be
976 retrieved in one chunk. Used in conjunction with "start" and "count".
978 SRW support for yaz-client. Use scheme http: to use it, e.g.
981 yaz-client no longer does (un)intelligent character set conversions
982 by default. Can be enabled with charset and marc_charset commands.
984 xmalloc trace fix for 64-bit systems such as DEC alpha.
986 Solaris 2.6 compile fix.
988 New function, cql_strerror() translates SRW error codes, as returned
989 by cql_transform_error(), into human-readable English strings. Used
990 in yaz-client diagnostics when appropriate.
992 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
993 converts it into a type-1 query which is sent to the server. This
994 makes CQL available for use with all Z-servers, as opposed to the tiny
995 minority that can handle CQL queries themselves.
999 New Debian package layout similar to the Redhat Package layout.
1001 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1002 and search result respectively.
1004 --- 2.0.1 2003/04/25
1006 Redhat package is now several packages: libyaz (runtime libraries),
1007 libyaz-devel (development and documentation, and yaz (utility programs).
1008 Package spec file by Morten Bøgeskov.
1010 New member 'schema' in struct bend_fetch_rr which the name of requested
1011 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1012 handler MAY set this to reflect the schema of the returned record.
1014 New member 'display_term' in struct scan_entry. GFS now sets member entries
1015 and allocates scan entries to be filled by user scan handler. In previous
1016 version, entries member was allocated by the scan handler. That still works,
1017 but the GFS will ignore member display_term - assuming it was NOT set by
1018 the handler. The fact that the GFS now allocates the entries both allows
1019 for new members and makes a scan handler easier to write.
1021 Fix CQL lex buffer overflow.
1023 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1024 SRU default recordPacking is string.
1026 SRU protocol support for frontend server.
1028 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1030 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1032 Added scan for the ZOOM shell (zoomsh).
1036 * String Identifers for Schemas (Amendment 5).
1037 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1038 Old definition for schema
1039 Odr_oid *schema; /* OPT */
1044 Z_InternationalString *uri;
1045 #define Z_Schema_oid 1
1046 #define Z_Schema_uri 2
1049 * resultCount parameter to Sort Response (Amendment 1).
1050 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1052 Support for SRW 1.0 over HTTP. This is an optional feature and
1053 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1056 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1057 on the same port. SRW SearchRetrieveRequests are mapped
1058 to bend_init,bend_search,bend_fetch,bend_close.
1060 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1062 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1063 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1065 ZOOM connections are SRW based if schem http is used for hostname
1066 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1067 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1069 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1070 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1071 distance=n, order=true/false, relation=le, prox unit=word. If
1072 n is omitted, distance 1 is used.
1074 Fixed problem with C compiler include path in wrong order.
1076 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1077 on Solaris. Patch from Ko van der Sloot.
1079 New MARC decode API. All new functions operate on a yaz_marc_t
1080 handle. The most important new functions are: yaz_marc_create,
1081 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1082 decode and destroy respectively. Decoder can produce formats
1083 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1084 include/yaz/marcdisp.h.
1086 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1087 to UTF-8, UCS-32, wchar_t or Latin-1.
1089 * Prototypes for yaz_iconv_-functions moved to separate header
1090 include/yaz/yaz-iconv.h.
1092 Make a few private functions 'static' in unix.c. This prevents
1093 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1095 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1096 are set when Init Response is received.
1098 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1099 but returns diagnostic set as well.
1101 New function yaz_strerror which is a portable wrapper for
1102 strerror/strerror_r/GetLastMessage.
1104 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1105 is returned for MARC. If type is "oai", then OAI MARC is returned.
1107 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1110 --- 1.9.2 2002/11/26
1112 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1114 Fix bad race conditions on SIGTERM and terminate gracefully in
1117 Move retrieval (data1) module to Zebra since nobody seems to be
1120 Add GRS-1 render for ZOOM using same format as yaz-client.
1122 --- 1.9.1 2002/10/05
1124 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1126 Fix broken ESpec handling in data1 module.
1128 SGML reader parses comments and makes them part of the data1 tree.
1130 Added several type casts so that YAZ compiles as C++ code.
1132 ZOOM didn't handle PDU encoding failures properly.
1134 Added more Bib-1 diagnostics (approved extensions).
1136 GNU configure: better check for iconv.
1138 More portable use of accept, getpeername. Check for socklen_t. Use
1139 int/size_t if socklen_t is not defined.
1143 PQF parser rejects bad queries - including those with extra
1144 characters in them. PQF parser used to silently ignore that.
1145 Cleaner API for PQF added, which allows you to get detailed
1146 error information for bad queries (see yaz/pquery.h).
1148 Fixed bug in ZOOM_record_get for type "database".
1150 Implemented mini iconv library supporting conversions between
1151 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1153 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1155 --- 1.8.9 2002/08/20
1157 Fixed ZOOM C record cache so that preferredRecordSyntax and
1158 elementSetName is used to check for already fetched records.
1160 --- 1.8.8 2002/08/02
1162 Added three members in bend_initrequest structure to facilitate
1163 character set negotiation.
1165 Fixed a bug in frontend server that could cause indefinite
1166 loops under rare conditions.
1168 Revised character set utilities (charneg.h) so that encoding
1169 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1171 For PQF, directive @term <type> sets term type for Scan/Search.
1172 Here <type> is general, string, numeric, null. The term type
1173 is inherited - just like @attr.
1175 New call odr_set_charset that sets character set conversion for
1176 international-strings on a ODR stream. Prototype is:
1177 int odr_set_charset(ODR o, const char *to, const char *from);
1178 The InternationalString is still represented as C string in YAZ
1179 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1180 won't). On the protocol level, you can use any encoding.
1182 Support for UNIX sockets in ZOOM.
1184 Solaris recv sometimes returns errno == ENOENT. It is treated as
1185 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1187 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1188 both client and server. Code by Morten Bøgeskov.
1190 --- 1.8.7 2002/05/22
1192 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1193 that they can be used directly from Visual Basic. You must recompile
1194 your windows APP if you're using ZOOM.
1196 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1197 Commands "lang" and "charset" sets language and character set respectively.
1198 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1199 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1201 Attributes from multiple CCL fields may be OR'ed rather than merged
1202 using directive "@field or". Fields are still merged by default -
1203 equivalent to "@field merge".
1205 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1208 Fixed bug in zget for parameter ExtendedServicesResponse.
1212 --- 1.8.6 2002/03/25
1214 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1216 Client displays USR.1:SearchResult-1 (hits per term).
1218 Additional Search Info for search in Generic Frontend Server.
1220 Fixed CCL parsing of "field=s".
1222 WIN32 installer - using the excellent NSIS software from nullsoft.
1224 Fixed CCL parsing of "field = - <number>".
1226 Added function yaz_marc_decode that decodes MARC for line mode
1227 display or XML (similar to that used by JZKit).
1229 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1230 Z39.50. But ISO/ILL was, however.
1232 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1233 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1235 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1236 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1238 --- 1.8.5 2002/02/03
1240 New YAZ client features: Command completion and new commands:
1241 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1242 Code provided by Jacob Poulsen.
1244 New call oid_trav, that visits all registered OIDs via callback.
1246 Function ZOOM_record_get now returns const char pointer rather than
1247 void pointer. It saves a lot of type casts.
1249 For YAZ client, command "auth" now allows you to set authentication
1250 in IdPass style. It is enabled when three tokens are given - order
1251 is user, group and password.
1253 Fix memory leaks in MARC record handling for ZOOM.
1255 New option for YAZ client, -k <kilobytes> that sets
1256 maximum record size. Similar to -k option for generic frontend
1257 server and yaz-ztest.
1259 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1261 Prefix query parser reports "fail" when bad attribute set is given.
1263 Fix in MARC decoder. Proximity logging. Fix for attribute set
1264 in scan handler for server. Patches by Shigeru Ishida.
1266 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1269 Configure option --with-openssl=<dir> now works when a directory is
1270 specified. Patch provided by Morten Bøgeskov.
1272 New option for YAZ client, -u <auth>, that sets authentication.
1274 ZOOM fix: error information was sometimes "missing", since error
1275 was cleared/reset too when it shouldn't.
1277 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1279 --- 1.8.4 2002/01/04
1281 Scan for ZOOM API. New object ZOOM_scanset. New functions
1282 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1283 ZOOM_scanset_destroy.
1285 New ZOOM function, ZOOM_connection_last_event, that returns type
1286 of last event (such as "receive data", "send data", "apdu received",
1289 New ZOOM option, schema, that specifies schema for retrieval.
1291 New CCL feature. Qualifiers can be aliases for one or more
1292 other qualifiers (if more than one is given, OR is used).
1294 ZOOM uses named result sets if target supports it.
1296 Two new YAZ client commands: . (dot, which sources a script of YAZ
1297 client commands), and ! (to execute shell command.). Implemented
1300 Working on Debian packages.
1302 --- 1.8.3 2001/11/19
1304 YAZ client enables named result sets only if target supports it.
1306 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1308 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1309 with key="host" to get same result.
1311 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1312 Function Z3950_resultset_record(s) returns references to records
1313 "owned" by resultset. To become owner use Z3950_record_clone.
1315 Function z_ext_record handles Extended Services. Thanks to
1318 --- 1.8.2 2001/11/12
1320 CCL Parser fix: ignore token comma when dealing with and-lists.
1322 Documentation updates for COMSTACK.
1324 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1325 Changed prototype Z3950_records. For some functions, int parameters
1326 were changed to size_t.
1328 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1331 New MARC decode/display function, marc_display_exl, which properly rejects
1332 non-ISO2709 records. YAZ client uses it.
1334 --- 1.8.1 2001/10/29
1336 Fix bug: local attribute set wasn't set correctly in PQF strings.
1340 * Old Z39.50 codecs no longer supported.
1342 Added ZOOM C binding. See http://zoom.z3950.org/
1344 Renamed states for COMSTACKs to avoid confusion with events.
1346 Implemented cs_look and proper cs_rcvconnect.
1348 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1350 Configure detects POSIX threads on OpenBSD.
1352 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1353 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1355 When error is returned from present handler, non-surrogate diagnostic
1356 is returned in present response (and fetch handler is no longer called).
1358 * Minor adjustments to pquery parser (PQF). Token characters may be
1359 escaped by using backslash (C-style).
1361 PQF parser allows string attribute values to be specified. For @attr,
1362 non-numeric characters after the equal-sign are treated as strings
1363 (e.g. @attr 9=title).
1365 CCL trunction character may be defined (@truncation in file)
1367 * function zget_ExtendedServicesRequest sets waitAction to
1368 waitIfPossible (was wait).
1370 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1373 CCL operator names may be set in field definition files (CCL_bibset).
1374 See ccl/bib1 for an example.
1376 Fixes in ASN.1 compiler for C++ compatibility.
1378 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1379 and "op_or" to avoid conflict with C++.
1381 Fixed problem with GNU readline detection on Redhat 7.0.
1383 Added step-size for Scan backend handler.
1385 Fixed bug that made the frontend server crash when no attribute
1386 set was specified for scan.
1388 Front-end server automatically switches to original working directory
1389 when installed as an NT service. Previously -w had to be specified to
1392 Added extended attributes for retrieval module (data1), so that data1
1393 records carry d1_readXML/SGML attributes. d1_read also supports
1394 null-data rules ( <tag/>)
1396 On UNIX when POSIX threads are available, a separate library libyazthread
1397 is created. Programmers should link with that library and the yaz library
1398 when using threads. The reason for the split was that some applications
1399 on Linux, such as Apache, doesn't work well when using shared objects that
1402 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1403 (or any frontend server) in SSL mode by specifying ssl: followed by
1404 address. Only tested on UNIX.
1406 Added feature for CCL module. Virtual structure s=al or s=ol generates
1407 and-list and or-list respectively instead of phrase search.
1411 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1412 log_mask_str. This was done to avoid name conflicts with other libraries
1413 (such as other PHP extensions).
1415 Added raw OID member for preferred record syntax (request_format_raw)
1416 and returned record syntax (output_format_raw) for backend fetch method.
1418 Config file yaz-config now accepts options so that it returns specific
1419 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1421 Shared library support for UNIX using GNU libtool.
1423 * Modified backend interface. Request/Response struct's replaced by
1424 one read/write C struct. For example bend_fetchrequest and
1425 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1426 Every handler - even search has to be registered in bend_init
1427 handler. This means that the YAZ library no longer refers to
1428 external functions and it makes it possible to make the whole
1429 thing a single DLL/SO.
1431 Added Segment handler for backend server.
1433 Added Zmbol/Zebra administrative functions to YAZ client.
1435 Threaded frontend server on UNIX (when POSIX Threads are available).
1436 Starting the server with option -T enables multi-threading.
1440 Added configure option --enable-comp/disable-comp to control use
1441 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1442 located in sub directory asn.
1444 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1445 in ${exec_prefix}/bin along with the other programs yaz-client and
1448 GNU automake used to maintain makefiles.
1450 Added several OID's.
1452 Changed retrieval module so that we can load records with no abstract
1453 syntax defined. Tagpaths in these records are fully composed of string
1456 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1460 On UNIX, the generated makefile now supports a proper 'make install'.
1461 The prefix can be set via GNU configure to set the install location
1462 (default is /usr/local).
1464 * YAZ programs client and ztest were renamed to yaz-client and
1465 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1466 locations, such as /usr/bin,/usr/local/bin,etc.
1468 * YAZ Header files were moved from include to include/yaz. YAZ Header
1469 files are referred to as include <yaz/log.h> rather than <log.h>.
1470 The YAZ include path (-I ..) is therefore the same as before. Programmers
1471 should update their #include statements or use -Ipath/include/yaz
1472 instead. The main motivation for doing this change is that YAZ header files
1473 can be installed in "standard" locations /usr/include,/usr/local/include
1474 without introducing conflicts, since ALL YAZ header files are stored
1475 in subdirectory yaz (under /usr/include for example).
1477 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1478 rather than project/workspace files. We switched because project files
1479 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1482 Changed name of logging function, logf, to yaz_log, to prevent name
1483 clash with some math-log functions. The YAZ header log.h defines logf
1484 to yaz_log (#define) so there should be no incompatibilities by this
1487 Added bend_start/bend_stop handlers for server. These handler are
1488 called on start/stop of server. For windows they are called whenever
1489 a service is started/stopped.
1491 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1492 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1493 in util/yc.tcl. The auto-generated C code structures are, in a few
1494 cases, incompatible with the old decoders. There are differences in the
1495 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1496 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1497 The preprocessor variable ASN_COMPILED is defined when the compiled
1498 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1499 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1500 wish to use the old encoders/decoders you can specify --disable-yc
1503 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1504 version so that it supports both new - and old version of DB Update
1506 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1507 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1508 change. The name parameter can be set to 0 in which no name is specified
1509 for the construction. The macros odr_implicit and odr_explicit sets name
1510 parameter to zero for the construction involved. New macros
1511 odr_implicit_tag and odr_explicit_tag are similar to the others,
1512 except that a name parameter is added. For programmers' that don't use
1513 ODR they probably only need to change the call to z_APDU and z_External.
1515 Added access control facility by interfacing the TCP wrapper library.
1516 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1517 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1518 name of the daemon and enables the access control as specified in
1519 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1521 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1522 den Dool <H.M.vdnDool@kub.nl>.
1524 Added reference ID parameter to most functions in server API - refer
1525 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1527 Changed name of ccl library to libccl.a (was ccl.a).
1529 Fixed bug in decoder for Explain (Category TargetInfo).
1531 Added support for GNU readline in client. Thanks to Jacob Poulsen
1532 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1534 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1535 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1536 IMPLEMENTATION! This change was made to the development version before
1537 the ZIG decided to retract the amendment. If any users MUST be
1538 compatible with the original Update definition, PLEASE CONTACT US, and
1539 we will include a separate definition corresponding to the old Update
1540 ES. Note that because of the change to the ASN.1 of the
1541 TaskPackageRecordStructure we cannot define a single structure that
1542 will support both versions.
1544 * Added const modifier to buffer parameter for some ODR/BER encoding
1545 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1546 completeWAIS, odr_dumpBER.
1548 Fixed bug in client.c which caused a crash when a scanResponse didn't
1549 contain positionOfTerm.
1551 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1552 * will cause an error in a client if a non-YAZ target sends both a
1553 * list of Scan entries and non-surrogate diagnostics.
1555 Retrieval module enhancements. Tag sets may be typed in the reference
1556 to it. From the .abs-file the "tagset" directive takes a third optional
1557 integer type for the tag set referenced. From a .tag-file the "include"
1558 directive takes a third optional type as well. The old "type" directive
1559 in the tag set itself is still recognized but acts as the default type
1562 Backend interface change. Individual Scan terms returned from bend_scan
1563 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1564 in include/backend.h.
1566 Retrieval module enhancements. Multiple tag sets and attribute sets may
1567 be specified in abstract syntax specs. Revised the error/warning for
1568 logging messages reported by the retrieval module when reading the
1571 Object Identifier system (oid_..) changed. The API is backwards
1572 compatible but the oid-routines now allocates new OID's when needed.
1573 Raw OID's may be specified in oid_getvalbyname.
1575 YAZ now uses GNU configure to generate Makefile(s).
1577 * Minor changes in some of the member names of DeleteResultSetRequest and
1578 DeleteResultSetResponse. See include/proto.h.
1580 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1581 and added member 'languages' in TargetInfo (which was missing).
1583 Changed the way attribute sets are handled in the retrieval
1584 module. These are now cached, just like the abstract syntaxes
1587 Changed YAZ so that it links with compiled ASN.1.
1589 Added Explain-schema definitions and mapping routines. The following
1590 Explain categories have been implemented: AttributeDetails,
1591 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1593 Fixed minor bug in Windows version of Server Library.
1595 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1597 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1599 Added EXTERNAL: UNIverse Resource Report (non-standard).
1601 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1602 ENUMERATED and SET OF.
1604 * Added 'const' to some of the char pointer arguments for the
1605 functions, data1_read_node, data1_getelementbytagname,
1606 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1609 Fixed bug in data1_insert_taggeddata - the last_child member of
1610 parent wasn't initialised.
1612 * Changed data1_read_record and data1_read_node so that the supplied
1613 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1614 doesn't refer to any parts of the "SGML"-buffer.
1616 Fixed bug in server library (Windows version of statserv_remove).
1618 * Changed code so that it compiles as C++. The type definition
1619 of Odr_fun which is a member of Odr_arm was changed. The result is,
1620 that an explicit typecast is needed for the fun pointer when
1621 using Odr_arm - as in:
1622 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1624 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1626 Implemented the new structured date and time definition as approved
1627 by the ZIG. Added schemaId element to the specificTag in Espec-1
1628 (also approved at the last ZIG). Thanks to RVDM.
1630 Added some Object identifiers (RVDM).
1632 Changed the Update Extended Service (RVDM).
1634 Added command "refid" to client which specifies referenceId for
1635 the following requests.
1637 Implemented extended service handling for server. See ztest.c
1638 for an example as well as backend.h. New handlers are registerd
1639 in the Init handler.
1641 * Changed interface for sort in server.
1643 Added new members to statserv_options_block. It allows a server
1644 to read options from another source than just the command line. Thanks
1645 to Charles Woodfield.
1647 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1648 renamed to zboolean. Some C++ compilers complained about the name.
1650 Minor changes to gils.abs. Added index 's' (sort) on title
1651 and date/time-last-modified.
1653 --- 1.4pl2 1998/1/30
1655 Fixed bug in server library regarding inetd mode (-i). This bug
1656 was introduced by release 1.4.
1658 --- 1.4pl1 1998/1/29
1660 Added sort facility in client and backend server interface.
1662 Fixed problem with dependencies in Makefile(s).
1664 Fixed bugs for encoders/decoders of extended services and
1667 Implemented sub-tree feature for schemas. Sub-trees are
1668 referenced in *.abs-files. See explain.abs for an example
1669 of the use of this feature.
1671 Modified bib1.att; local attributes for ANY didn't include
1672 ANY itself (only affects use of the retrieval module).
1674 Fixed bug in plain SGML reader in function data1_read_node:
1675 tags with prefix "var" was incorrectly interpreted as variants.
1677 Added feature "sub-schemas" to enable references to - and definitions
1678 of - group of elements.
1680 * Removed member parent from type data1_element (in data1.h).
1682 Implemented function odr_nullval() that returns the value of
1685 * Removed member num_children from data1_node (in data1.h).
1687 Made NT service interface part of the server library. The
1688 function statserv_main uses the NT service when required and
1689 calls the statserv_start / statserv_close routines.
1691 Routine zget_SearchRequest and zget_PresentRequest fills
1692 resultSetName/Id member with "default" instead of "Default".
1694 Fixed memory leak in server. Request queue member wasn't freed.
1696 Fixed nmem_exit so that memory is freed.
1700 Revised the CCL parser utility to be thread safe.
1702 Added function, oid_ent_to_oid, to replace the function
1703 oid_getoidbyent, which is not thread safe.
1705 * Added nmem_init and nmem_exit to initialize and release
1706 NMEM resources. Function nmem_init should be called once in the
1707 initial thread before NMEM/ODR is used. statserv.c and client.c
1708 have been changed accordingly. The change was necessary to make
1709 NMEM thread safe. The NMEM memory pool is shared amongst threads
1710 in a process. Unix-based applications will still work fine without
1713 Added NT Services interface for the the Z39.50 (statserv) Server.
1714 Refer to the ztest.c source on the usage.
1716 Windows 95/NT port using MSVC5.0. Project files are included in the
1719 * Defined new 'global' handle for the retrieval (data1) system. The
1720 new handled, data1_handle, describes the state of the data1 system.
1721 This handle is passed as first argument to virtually all
1722 data1 related routines. The functions data1_create and data1_destroy
1723 creates and destroys a data1 handle respectively.
1725 Added ODR encode stream member to all backend request structures
1726 init, search, scan etc. This stream should be used to allocate all
1727 memory used for the response when thread safe operation is needed.
1729 Changed the comstack utility, cs_addstr, to be thread safe. The
1730 returned hostname string returned by the function is now part the
1733 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1734 function. The cs_straddr takes a COMSTACK handle as argument, so this
1735 function must be used after cs_create and before bind/connect.
1736 This function is thread safe.
1738 Moved test server to 'ztest' directory - generic server code still
1739 in 'server' directory.
1741 Made prefix query (pquery.c) utility thread safe.
1743 Added new function modifier YAZ_EXPORT to 'export' public DLL
1744 functions when using windows (see include/yconfig.h).
1746 Added definitions to the OID database (util/oid.c) (RVDM).
1748 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1750 Added call to ccl_rpn_delete in client program.
1752 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1753 release of RPN structure.
1755 Added support for C++, headers uses extern "C" for public definitions.
1756 With input from RVDM.
1758 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1759 Thanks to Ronald van der Meer (RVDM).
1761 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1763 Added support for private extensions to the OID database
1764 (oid_setprivateoids()). Thanks to RVDM.
1766 Added optional, physical ANY (key replication)
1768 Fixed null-reference problem in GRS-1 output filter.
1770 Proximity operator added to Prefix Query Format (PQF).
1772 In test client command "base" accepts multiple databases.
1774 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1778 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1780 Smallish bug-fixes in the new encoders/decoders (explain).
1782 Bug fixed in DeleteRequest.
1784 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1786 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1788 Added SOIF syntax (using private OID for now) to retrieval module and client.
1790 Added Update extended service.
1792 Added SearchResult-1 additional info structure.
1794 Added optional CCL (ISO8777) interpreter as separate module. Available
1797 --- 1.2 1996/6/10 (1st anniversary release)
1799 Added Summary record syntax. Lightly tested.
1801 Added OPAC record syntax. Untested.
1803 Added ResourceReport service encoders/decoders. Untested.
1805 Fixed bug in z_Unit - wrong tagging on unitSystem.
1807 Fixed bug in the DiagRecs decoder.
1809 Added options for max PDU size and session timeout to frontend-server.
1811 Added documentation of query-language parsers and other supporting utilities.
1813 [frontend-server] Added Attribute set to the bend_scanrequest API.
1815 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1816 surrogate diagnostics were generated.
1818 [retrieval] Allow multiple local values for attribute.
1820 [retrieval] Allow multiple attributes per element in .abs files. index type.
1822 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1824 --- 1.1pl2 1996/4/10
1826 Minor changes, mostly specific to Zebra's requirements (retrieval)
1830 Repaired bug in frontend server when running multiple listening
1831 endpoints in dynamic mode.
1833 z_External() now won't break if a known, ASN.1 value comes encapsulated
1834 in an octet-string. The value will pass through unmodified in an Odr_oct.
1836 Added a bit of code to the demo client to decode & display
1837 ASN.1-structured records represented in the octet-aligned branch of
1838 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1840 Added z_ext_getentbyref() to the ASN module. Doc updated.
1842 * Completed the SCAN definition in the ASN module. This may break SCAN
1843 code based on older YAZ-versions at compile-time. The fix is easy -
1846 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1847 under the SCAN definition. Remember to initialize this, server-people.
1849 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1850 that this does not extend to ODR and ASN.
1852 Comstack allows insertion of established socket (primarily for
1853 inetd-operation of servers). Doc updated.
1855 Front-end server can now start from the inetd in TCP mode. Doc
1858 --- 1.0pl4 1996/1/24
1862 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1863 the rank and record number.
1865 Adjustments to the frontend server.
1867 Fixed diagnostic BER dumper. It ignored the file argument.
1871 Various changes to retrieval module.
1873 Changed the union discriminators of the protocol files from enums to
1874 ints paired with #defines.
1876 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1879 *Changed operator in the RPN structure to 'roperator', again to avoid a
1882 Fixed problems in Explain decoders/encoders.
1884 --- 1.0pl2 1995/12/6
1886 Memory bug in log module fixed.
1888 --- 1.0pl1 1995/12/5
1890 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1892 Bug in Explain DatabaseInfo module fixed.
1894 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1898 The shift to v1.0 signals that we now consider the *core* functionality
1899 of YAZ reasonably stable (the core being more or less equivalent to
1900 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1901 tested (Explain not at all - though that will happen soonish).
1903 Minor changes to code to support Windows port.
1905 Various minor changes after we're getting to use GRS-1 & co. more.
1907 Added Espec-1 format.
1909 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1910 of the protocol and it cannot be selected when encoding (maps into 'string'
1911 when decoding). Needed to talk to some servers.
1913 Demo client can request simple element set names.
1915 Added Diagnostic Format encoders/decoders.
1917 Added simple Close handling to frontend server (no hooks for resource
1918 reporting yet), and demonstration client.
1920 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1922 --- 1.0b3 1995/08/24
1924 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1925 handled incorrectly when records were requested in the searchResponse. This
1926 will only affect you if you use the frontend-server.
1928 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1929 Test-client will ask for and print GRS1. Ztest will return dummy records
1932 Added Explain encoders/decoders to the service-level API. Untested.
1934 Added Extended Services: Item Order encoders and decoders to the Service-
1935 level API. Untested. We could use a recent copy of the pertinent bits
1936 of the ILL protocol to add those bits.
1938 Added diagnostic format 1 encoders/decoders to the service-level API.
1941 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1942 odr_cons.c, which causes a more correct output.
1944 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1945 was always set to 0 when no records were requested in the searchRequest.
1947 * Added better external-handling. This shouldn't harm old code that
1948 *encodes* externals. It can break code that looks for a
1949 'single-ASN1-type' representation, since those types that are known
1950 are now decoded immediately. Look at the SUTRS sample code in
1951 seshigh.c and client.c. Documentation updated.
1953 Handling of structured records in bend_fetchresponse. Length -1 marks
1954 structured record, type is deduced from format field.
1956 --- 1.0b2 1995/06/27
1957 Fairly quick maintenance release to add SUTRS support.
1959 Fixed handling of SUTRS records in the demonstration client.
1961 * Added format field to the bend_fetchrequest and bend_fetchresponce
1962 structures of the backend API (frontend server). When the record is
1963 returned, the value of the format field is mapped to an OID. The
1964 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1965 of the record. The special value VAL_NONE in the bend_request means
1966 that no specific format was requested by the client. Documentation
1967 updated accordingly. Test server (ztest) will return a fixed dummy
1968 SUTRS record if your client requests SUTRS.
1970 Documentation updated accordingly.
1972 You can now set external libraries and RANLIB support in the top-level
1976 First public release.
