1 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2 spec, at http://www.loc.gov/standards/sru/record-update/
3 This has changed the binary layout of the following structs:
4 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
5 bend_update_rr . Patch by Ko van der Sloot.
7 Added GFS utility function bend_assoc_is_alive which returns 1 if
8 association is still alive (client is connected); 0 otherwise (client
9 closed connection). This allows busy servers to stop working for
12 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
14 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
15 Client code may now interrogate options such as "init_opt_sort" to
16 find out whether the server claims to support various options.
20 Added utilities yaz_{set,get}_esn to set/get element set name from
23 Removed the build of libyazthread.la. The libyaz.so is the threaded version
24 of YAZ and has been so since YAZ 2.1.10.
26 Implemented ZOOM_record_error which returns error information for
27 record (surrogate diagnostic).
31 Updates for SRU Update by Ko van der Sloot:
32 1. Changed name from "operation" to "action"
33 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
34 versions in the code, marked as 'backward compatible'.
35 3. Added diagnostics for SRU Update.
37 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
39 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
41 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
43 For GFS, fixed problem with SRU diagnostic 'First record position out of
44 range' being issued for 0 hits.
46 zoomtst10 part of Windows Build.
50 Implemented yaz_filepath_comp which splits a path into file path
51 components (required by Zebra 2.0.3+).
53 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
54 BSD inspired license until now so this should not have any real impact on
55 anybody. See http://www.opensource.org/licenses/bsd-license.php
57 Fixed bug #687: Missing log lines.
59 Fixed bug #678: CQL to PQF translation does not preserve double-quote
62 Fixed bug #689: SRU diagnostics to be added.
64 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
65 whether a connection is idle (no more work do do).
69 Change type of optval from long to int for invocation of setsockopt with
70 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
72 Added support for specifying the max log file size for the Generic
73 Frontend Server. The size is given with option -r.
77 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
81 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
84 Fixed bug in Generic Frontend Server that could cause a server to stop
85 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
87 For the generic frontend server, the maximum record size is used as maximum
88 size of incoming packages (SRU + Z39.50). The value until was previously
89 only used in Z39.50 Init negotiation and, later, in a session controlled
90 sizes of records returned. This is controlled using -k option. It can be
91 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
95 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
98 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
100 New option for yaz-marcdump -lpos=value which allows setting a portion
101 of MARC header to a certain value.
103 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
105 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
106 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
108 --- 2.1.26 2006/08/15
110 Fixed problem with SRU mode type (soap, get, post) for yaz-client
113 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
115 --- 2.1.24 2006/08/08
117 Fixed MARC ISO2709 encoding routines to deal with character set
120 Minor changes to GFS logging. Database included in search request log
123 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
124 cached/multiple records.
126 Shared libraries are built by default on Unix+configure.
128 Changed cql2pqf transformation to use a different evaluation order. The
129 new order is: always, relation, structure, position, truncation, index
130 and relationModifier. Old order was: always, relation, relationModifier,
131 structure, index, position, truncation. Note that the the latter ones
132 override former ones for identical attributes.. The new scheme means that
133 it is possible to override any existing attribute with a relationModifier.
134 And also that it is possible to override everything for the index rule
135 (except the ones listed in relationModifier). No order is perfect but this
136 one, we believe, covers more real cases.. The "always" should have been
137 called "default", since the attributes there can be overridden with all
140 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
141 compilation phase, but also for yaz-config --cflags output. This allows
142 us to have public headers with Libxml2 stuff in them . It should also,
143 eventually, make Libxml2 checks redundant in packages using YAZ, such
146 --- 2.1.22 2006/06/15
148 Changed SRU update structure bend_update_rr so that SRU diagnostics are
149 stored in uri, message and details.. Previously diagnostics were stored
150 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
151 compatibility.. but he's probably the only one affected, so.
153 Added support for CCL, compiled on the client side, in ZOOM-C. This
154 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
155 input; the resulting query objects can be used for for searching with
156 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
158 YAZ' configure searches for OpenSSL by default.
160 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
161 SL_CTX_use_certificate_file. See
162 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
163 for more info. Thanks to Ko van der Sloot.
165 --- 2.1.20 2006/06/02
167 Bug #600: SRU GET, POST support for yaz-client. Introduced
168 command 'sru' which selects method SOAP/GET/POST.
170 Allow missingValueAction to be specified for the sortspec string -
171 function yaz_sort_spec. By default, the missing value action is null.
172 Use ! to specify "abort". Use = followed by stringvalue to specify default
175 Ensured that Present-handler (if defined) is called in GFS before any call to
176 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
177 searchRetrieve requests.
179 Documentation for YAZ is now based on the Docbook XML/XSLT using
180 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
181 is no longer depending on jade/openjade or docbook-to-man scripts.
182 PDF is no longer part of the distribution - but can optionally be
183 made using DSSSL/jadetex or FOP.
185 Added retrieval handling support in Generic Frontend Server to support
186 conversion between MARC/XML as well as XSLTtransforms. See
187 etc/yazgfs.xml for an example.
189 Added Authentication support to Generic Frontend Server in SRU
190 mode. Authentication using HTTP Basic is supported, as is the use
191 of 'x-username' and 'x-password' parameters in the request itself.
193 Added support for a new character set MARC8s identical to MARC8 except
194 that it converts combined characters to single Unicode characters in the
195 Latin-1 range (when possible).
197 --- 2.1.18 2006/04/24
199 ASN.1 compiler 0.4: generates brief Doxygen file header for
200 generated .h/.c files.
202 Utility yaz_iconv now supports conversion to MARC-8.
204 New facilities for the MARC module. The reading - and writing of
205 content are separate methods for the yaz_marc_t handle. The following
206 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
207 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
208 format). Write functions have prefix yaz_marc_write_.. The existing
209 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
210 available. Removed support for OAI-MARC and simplexml (not the
211 simplexml from PHP5).
213 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
214 to be returned for this connection.
216 --- 2.1.16 2006/03/31
218 Allow multiple languages and charsets to be specified with
219 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
220 negcharset iso-8859-1,utf-8
222 Translation of proximity nodes from CQL into PQF now works.
224 Moved to automake 1.8, 1.9.
226 Added function yaz_log_set_handler which allows a log handler to be
227 installed. This handler will be called for all log messages. Output
228 to file is also produced; but that can be disabled by passing NULL
229 fname to yaz_log_init_file.
231 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
233 For SRW (including GFS), accept application/soap+xml as content-type
236 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
237 produces NO stylesheet reference even if a default stylesheet is specified
240 --- 2.1.14 2006/03/14
242 Updated Windows package to include yazd.dll + yazd.lib for the
243 Development component.
245 If the environment variable YAZ_LOG is set, then it is used as a
246 string indicating the default level of logging to use if not
247 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
248 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
249 used as before. So, for example, to omit warnings from YAZ logging,
252 cql_transform() now map structure and other attributes before indexes,
253 so that index-specific structures and other attributes can override
254 defaults. So now a combination of mapping specifications such as:
256 index.dc.date = 1=date-modified 4=5
257 does the right thing.
259 cql_transform() now also respects the "always" mapping specification,
260 which establishes an initial set of attributes to be used for all
261 terms except where overridden by more specific attributes associated
262 with the index, relation or modifier.
264 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
265 which mode to use; one of "post", "get" or "soap" (SRW, default).
267 Fixes for yaz_iconv routines: changed trie-based character set conversions
268 to use only non-negative values for bit fields due to Sun's C compiler not
269 supporting negative values.
271 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
272 sequences where not read correctly. Fix by Rustam Usmanov.
274 Updated win/makefile to use options, settings which makes things
275 compile with VS C 2005.
277 --- 2.1.12 2006/02/01
279 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
281 In ZOOM socket code, use select instead of poll on MacOSX.
283 ZOOM-C now support client-side compilation of CQL into RPN that is
284 sent to the server, enabling CQL to be used against all Z39.50
285 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
286 ZOOM_query object, and submit it using ZOOM_connection_search().
287 The CQL-to-RPN translation uses a configuration file, the name of
288 which must be specified in the Connection's "cqlfile" option.
290 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
291 function, which takes as its start-term parameter a ZOOM_query object
292 (which may have had either CQL or RPN set into it).
295 --- 2.1.10 2005/11/29
297 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
298 GFS to support this as well. Backend handler, bend_srw_update, does the
299 update work. Code contributed by Ko van der Sloot.
301 Allow retrieval of Search Result-1 information in ZOOM by the use of
302 options that are attached to a result set. ZOOM documentation updated
305 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
306 UTF-8 conversion. Patch by Raj Patel.
308 Added option -m to GFS to control formatting of timestamps in log file.
310 Added 'exit' as synonym for 'quit' in yaz-client
312 Added support for specifying SRW resultSetId + resultSetIdleTime in a
313 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
314 for the new members. Patch by Ko van der Sloot.
316 Added support for SRU POST. It is supported for content-type
317 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
319 Do not build the separate Multi-threaded (MT) library libyazthread.la.
320 Instead make the library libyaz.la multi-threaded. Threading as a whole
321 can still be disabled by configure option --disable-threads. Previosly,
322 with older GLIBCs there were problems with MT libs under Apache. This
323 has now been fixed a long time ago.
325 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
328 CQL module modified to be case insensitive for relations/indexes/operations.
330 Fixed bug in CQL transform code: incorrect value relationModifieder
333 Added 'show all' command for yaz-client which retrieves all results
336 Added new yaz-client, xmles, which takes a (private) OID and
337 a document to be sent as an extended service request.
339 Describe new yaz-client commands wait_response and set_auto_wait.
341 Increase TCP/IP listener backlog from 3 (which I am guessing was
342 copied from the SunOS manual entry way back when) so SOMAXCONN, so
343 that the socket will queue as many incoming connections as it's able
344 to handle ongoing connections. In other words, it will never now
345 refuse a connection that it would be able to handle merely because
346 it's not got around to accepting() enough of the pending connections
347 yet. This is the behaviour anyway under Linux, where the listen()
348 argument is ignored; but not under BSD and on systems such as
349 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
350 YAZ-based servers should now be uniform across operating systems in
353 yaz-marcdump uses 64-bit file access on some systems. This is enabled
354 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
355 This allows yaz-marcdump to read large MARC batches (>2 GB).
357 Modified all YAZ source files - except the source which is auto-generated
358 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
361 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
362 corresponding to the existing *_setl() function. These allow option
363 values containing arbitrary valuues.
365 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
366 ZOOM_resultset_sort() in new applications. Its behaviour is identical
367 except that it returns an indicator of whether or not the sort
368 criterion was accepted (0 for OK, -1 for invalid).
372 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
373 MARC output rather than returning "new" buffer.
375 yaz-client warns about unknown init options.
377 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
381 Added support for SRW sort in Generic Frontend Server. Patch
382 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
383 sortKeys - or NULL if none is provided.
385 Fixed bug #307: It was impossible to specify indefinite/no timeout
386 for ZOOM_event. Special timeout value -1 now means indefinite timeout
389 Added support for multiple languages and charsets to be specified in
390 ZOOM. Each charset/language is separated by a blank. If negotiation is
391 in effect in init-response, Option
392 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
393 Code based on patch by Vasiliy Osadchuk.
395 Fixed bug #306: infinite recursion that occurred when calling
396 yaz_log_level_init as the first call (before other log level or
399 Fixed bug in scan handling in front end server: if preferred-Position-In-
400 Response was non-present, a NULL pointer referece was performed.
404 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
405 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
406 now defined for all those error codes. So instead of putting 109 in
407 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
408 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
410 Modified the yaz-marcdump utility to skip garbage bytes between MARC
413 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
415 Program yaz-client now exits and produces an error message if multiple
416 Z39.50 servers are specified on the command line (none or one allowed
419 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
424 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
426 Fixed bug #272: Preserve spacing for CCL terms.
430 Added support for virtual hosts and multiple backend servers for
431 the YAZ frontend server. The configution is XML based and
432 support specificition of CQL to RPN mappings and explain information.
433 See section "Virtual Hosts" in the YAZ manual.
435 Extended OPAC display utility. OPAC display utility renders
436 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
437 to supplement yaz_marc_decode_wrbuf.
439 Fixed a bug in MARC decoder that could caused it to crash for some
440 invalid MARC records. More diagnostics and warnings where added in
441 XML output (warnings, etc are stored in comments).
443 --- 2.0.34 2005/02/08
445 Fixes for UNIX domain sockets. Bug #261.
447 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
449 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
450 Added yaz_marc_subfield_str which defines subfield lead string which is
451 used in YAZ_MARC_LINE format. Default string is blank+$. Added
452 yaz_marc_endline_str which defines end of fields string used in
453 YAZ_MARC_LINE format. Default string is newline.
455 Experimental support for MarcXChange. This format can be produced
456 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
457 http://www.bs.dk/standards/MarcXchange.xsd
459 Added yaz-client commands scansize that sets maximum number of
460 entries to be returned by scan.
462 --- 2.0.32 2005/01/11
464 Added support for SRW scan in yaz-client and Generic Frontend Server.
466 * Added whereInList member to SRW Scan Term.
468 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
470 Fixed NMEM system to return aligned blocks on the smallest boundaries
471 that are suitably aligned for all possible types on the particular
472 architecture YAZ is being built for.
474 --- 2.0.30 2005/01/04
476 Fixed numerious warnings that was issued with newer versions of GCC.
478 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
479 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
482 Make YAZ Generic Frontend Server slightly faster.
484 Enhance (and reduce) logging for Generic Frontend Server.
486 Revert YAZ log system so that it flushes every write operation
487 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
489 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
490 instead of LOG_, due to name clash with syslog(3). LOG_ are still
491 present. New applications should define YAZ_USE_NEW_LOG=1 - this
492 will effectively disable old definitions.
494 --- 2.0.28 2004/11/09
496 Added yaz_log_time_format which specifies log format using
499 Added yaz_log_module_level which returns mask for a module. Value
500 is non-zero mask a if module is enabled; zero if disabled.
502 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
503 in include/yaz/cql.h.
505 Fixed bug #176: Dont throw diagnostics on empty SRU args.
507 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
509 Fixed bug #172: RPM builds does not enable SSL.
511 Doxyfile.in part of dist. Doxyfile generated by configure.
513 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
514 are given and the corresponding component does not exist.
516 Extend CCL documentation in YAZ reference. Describe r=r.
518 --- 2.0.26 2004/10/01
520 Fixed MARC->MARCXML conversion to properly deal with
521 fields, subfields, indicators having non-ASCII characters.
523 Fixed MARC->MARCXML conversion so that ASCII control characters
524 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
527 Added YAZ GFS support for conversion from Z39.50 surrogate
528 diagnostics to SRW surrogate diagnostics.
530 Bug fix: YAZ GFS did not return schema in explainResponse.
532 --- 2.0.25 2004/09/30
534 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
535 now converts recordSchema to elementSetName as well as schema URI.
537 Fixed bug in COMSTACK that prevented HTTP request packages from being
540 --- 2.0.24 2004/09/29
542 Added CCL facility r=r "range" which is similar to r=o "ordered" but
543 does not require white-space before and after the dash in a range, e.g.
544 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
547 Fixed a few AC_TRY_LINK configure tests that did not operate properly
548 due to new GCC removing "redundant" code.
550 Added yaz-client commands scanpos and scanstep that sets preferred
551 position and step-size for scan.
553 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
555 Added CCL utility ccl_qual_buf which parses one or more CCL
556 spec lines in a buffer.
558 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
559 of name and value - ignoring empty lines and comments.
561 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
563 Added odr_get_element_path which returns current element path for an
564 ODR handle. This utility is useful in error handling or user-defined
567 Added ODR_PRINT utility odr_set_stream which is is a more generic
568 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
569 to a write function and pointer to close function. The close function - if
570 non-NULL - will be called during odr_destroy.
572 Fixed bug in CCL parser where truncation char was not removed from
573 right side when truncation=both was in effect.
575 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
578 --- 2.0.23 2004/08/11
580 Fix buffer overrun in CQL parser when dealing with proximity (%).
582 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
583 to UTF-8/UCS conversion is now only based on codetables.xml.
585 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
587 --- 2.0.22 2004/08/06
589 Add support for more "commit changes" in ZOOM (uses Extended Services).
591 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
594 Yet another small fix for configure of SSL.
596 --- 2.0.21 2004/05/14
598 Fix SSL libs for configure when --with-openssl=DIR is given.
600 --- 2.0.20 2004/05/10
602 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
604 SSL comstack now uses yaz.pem certificate file on server side
605 by default. Certificate filename can be configured by calling
606 comstack function cs_set_ssl_certificate_file before cs_bind is used.
608 Fix bug regarding multiple calls to ZOOM_connection_connect.
610 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
612 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
613 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
615 ZOOM now allows inspection of X509 peer certificate for verification.
616 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
618 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
619 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
620 as "modular" but it simplifies things.
622 Added cs_get_peer_certificate to that returns peer X509 PEM.
624 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
625 NULL if SSL is unavailable.
627 Documentation about MARC decoding tools.
629 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
631 --- 2.0.19 2004/03/30
633 Rename CHANGELOG to NEWS to follow GNU style packing.

665 Another fix for decoding of XML packed records.
667 --- 2.0.14 2004/02/25
669 Fixes for Chunked encoding. White space not ignored after length spec.
671 Update NS and use default NS for SRW diagnostic elements.
673 --- 2.0.13 2004/02/23
675 Implement ZOOM_resultset_cache_reset which resets record cache.
677 Implement ZOOM_resultset_sort which sorts a result set.
679 Implement chunked HTTP transfer.
681 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
683 --- 2.0.12 2004/02/16
685 Added member 'schema' to bend_explain_rr structure so that backend
686 can specify explain record identifier. Defaults to Zeerex 2.0.
688 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
690 --- 2.0.11 2004/02/16
692 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
695 Added init command for yaz-client which sends "extra" init request.
697 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
698 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
700 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
702 Make ZOOM error code for "invalid query".
704 Fixed compilation for SSL which wasn't properly enabled for all platforms.
706 --- 2.0.10 2004/02/05
708 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
711 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
713 Added option -p <file> to make Generic Frontend Server to write PID file.
715 Added option -D to put Generic Frontend Server in background on its own.
717 Make ZOOM C recognize option "password". If unset, "pass" is used
718 (for backwards compatibility).
720 Fixed a bug in Generic Frontend Server that could make it crash if a
721 client sets characterSetNegotation bit, but didn't pass negotiation stuff
724 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
725 Must be issued before open, in order to be in effect.
727 --- 2.0.9-6 2004/01/12 Debian/Windows
729 Make the SRU server more picky WRT unknown params, etc.
731 Bug fix: ZOOM scan response didn't return displayTerm - when present.
733 New YAZ client command, options, that sets Z39.50 options.
735 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
736 options from a string of tokens (one token for each option bit).
738 Update SRW diagnostic code messages.
740 --- 2.0.9-5 2004/01/07 Debian/Windows
742 Handle user defined stylesheet for SRW/SRU.
744 --- 2.0.9-4 2004/01/06 Debian/Windows

748 --- 2.0.9-3 2004/01/06 Debian/Windows
750 Fix a bug with decoding of XML packed records.
752 --- 2.0.9-2 2004/01/05 Debian only
754 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
756 Fix bug in SRW/SRU diagnostics decoding.
760 Fixed bug in Generic Frontend Server which could drop records exceeding
761 preferred message size. Reported and fixed by Irina Dijour.
763 Fixed calculation of package size for structured records in Generic
764 Frontend Server. Reported and fixed by Irina Dijour.
766 Fixed namespace for SRW/SRU diagnostics.
768 Fixed SEGV in yaz-client that occured for HTTP connection errors.
772 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
773 this version is incompatible with version 1.0 and older YAZ SRW/SRU
776 CQL changes to reflect recent changes to the specification:
777 * Documentation talks about context sets instead of index sets.
778 * Documentation talks about indexes instead of qualifiers.
779 * The CQL-to-PQF transformer's configuration file now uses
780 "index.set.name = <attributes>" instead of the old form
781 "qualifier.set.name = <attributes>". (Both forms are still
782 understood but the latter is deprecated.)
783 * CQL terms with no explicit index specified are now interpreted as
784 cql.serverChoice instead of srw.serverChoice (which of course
785 behaves exactly the same.)
789 MARC conversion can now generate ISO2709 output in another
790 character set. yaz-marcdump uses this facility if you invoke it
793 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
794 functions from there can be used from C++.
798 Frontend server now transfers memory from decoded packages to stream
801 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
802 references to show up.
804 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
805 the ZOOM Abstract API. The older names for the same options are still
806 also supported for the benefit of old applications.
808 ZOOM-C supports "implementationId" and "implementationVersion" options
809 to go along with "implementationName". These allow the user code to
810 specify identification strings to be sent to servers.
811 Add OID for the new ExtLite attribute set.
813 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
814 as requested/supplid by Ere Maijala <ere@atp.fi>
816 For generic frontend server, reverse the order of
817 "toolkit-supplied / application-supplied" strings sent as implementationId,
818 Name and Version. Also, remove the spaces around the slash. This brings
819 the GFS in line with the behaviour of ZOOM-C on the client side.
821 Add function ZOOM_scanset_display_term.
823 yaz-client shows scan displayTerm if present.
825 Utility yaz-iconv is now installed by default along with the man page
828 Extend configure check for OpenSSL to use pkg-config where available (such
831 Incorporate patch by Morten Bogeskov which allows a Unix file socket
832 server to specify uid/gid/mask for socket using the format
833 unix:[user=uid,][group=gid,][umask=mask,]file=path
834 If file= is omitted the existing format is assumed, e.g.
836 in which case the mask is 0666 (rw for everybody).
838 Major restructure of YAZ source. All source in libyaz is in src directory.
839 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
840 util (utility programs such as ASN.1 compiler, yaz-marcdump).
842 Added man page for utility yaz-marcdump (used to be called marcdump).
843 yaz-marcdump is installed by 'make install'.
845 Fixed a memory leak in Generic Frontend Server that occurred when decoding
846 of incoming package failed.
848 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
850 Change prototype of odr_perror: add const to message string.
852 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
854 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
855 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
856 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
857 DNS lookup. There should not be any compatibility problems with this
858 assuming that blocking=1 or 0 is used.
860 Fix bad reference in UNIX comstack in function cs_addrstr.
862 Fix for compilation on AIX.
864 The generic front-end server (server/seshigh.c) now supports returning
865 Init diagnostics to the client in User-information-field, in
866 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
871 Allow any CQL relation (not just all,any,exact,scr).
873 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
874 that features the same UI.
876 Implemented command update0 in YAZ client which is equivalent to
877 update but uses old of Ext Update ASN.1.
879 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
880 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
881 Previously no OID was used for this info.
883 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
884 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
885 returns 'malformed search term' otherwise.
887 SortResponse member resultCount now set to NULL in sort handler of
890 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
893 Add three new utility functions for translating OIDs between various
894 formats -- symbolic name such as "Usmarc", minus-1-terminated int
895 arrays and dotted strings such as "1.2.840.10003.9.5.1":
896 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
897 char *oid_to_dotstring(const int *oid, char *oidbuf);
898 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
900 Reverted modifications for ES Update definition for z_IU0Update
901 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
902 is back to YAZ 2.0.2.
904 String value attributes for CCL parser.
906 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
907 which their FirstSearch server returns in Init responses, sometimes
908 carrying useful diagnostic information when Init fails. This has the
909 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
910 "z39.50/oclcui.asn", where its definition is somewhat different from
911 what OCLC document on their web-site, as required to interoperate with
914 Support for anonymous authentication in yaz-client. Use the command
917 * Fix the OID of the Index Data-local "admin" Extended Service from
918 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
919 the 1000, which indicates a locally-defined OID, was a mistake.
923 Fix CCL directive @case handling so that it affects string match for
924 both CCL keywords and qualifiers.
926 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
927 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
928 Decoder has been updated with ASN.1 changes as listed in
929 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
930 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
931 z_IUUpdate, remains unchanged.
933 ZOOM_record_get may now return a record in a specific character set.
934 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
935 "from" is the character set of record as returned by target. "to" is
936 the character set to be returned. If omitted, "to" is UTF-8.
938 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
940 New ODR utility, odr_getelement, which returns name of element for
941 which encoding/decoding failed.
943 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
944 in cases where a required element was omitted.
946 Bug fix: some MARC8 sequences were not converted.
948 New ZOOM option "step" which specifies number of records to be
949 retrieved in one chunk. Used in conjunction with "start" and "count".
951 SRW support for yaz-client. Use scheme http: to use it, e.g.
954 yaz-client no longer does (un)intelligent character set conversions
955 by default. Can be enabled with charset and marc_charset commands.
957 xmalloc trace fix for 64-bit systems such as DEC alpha.
959 Solaris 2.6 compile fix.
961 New function, cql_strerror() translates SRW error codes, as returned
962 by cql_transform_error(), into human-readable English strings. Used
963 in yaz-client diagnostics when appropriate.
965 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
966 converts it into a type-1 query which is sent to the server. This
967 makes CQL available for use with all Z-servers, as opposed to the tiny
968 minority that can handle CQL queries themselves.
972 New Debian package layout similar to the Redhat Package layout.
974 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
975 and search result respectively.
979 Redhat package is now several packages: libyaz (runtime libraries),
980 libyaz-devel (development and documentation, and yaz (utility programs).
981 Package spec file by Morten Bøgeskov.
983 New member 'schema' in struct bend_fetch_rr which the name of requested
984 schema (SRW/SRU) for record (or NULL if none was given). The fetch
985 handler MAY set this to reflect the schema of the returned record.
987 New member 'display_term' in struct scan_entry. GFS now sets member entries
988 and allocates scan entries to be filled by user scan handler. In previous
989 version, entries member was allocated by the scan handler. That still works,
990 but the GFS will ignore member display_term - assuming it was NOT set by
991 the handler. The fact that the GFS now allocates the entries both allows
992 for new members and makes a scan handler easier to write.
994 Fix CQL lex buffer overflow.
996 SRW/SRU recordPacking. For SRW default recordPacking is string. For
997 SRU default recordPacking is string.
999 SRU protocol support for frontend server.
1001 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1003 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1005 Added scan for the ZOOM shell (zoomsh).
1009 * String Identifers for Schemas (Amendment 5).
1010 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1011 Old definition for schema
1012 Odr_oid *schema; /* OPT */
1017 Z_InternationalString *uri;
1018 #define Z_Schema_oid 1
1019 #define Z_Schema_uri 2
1022 * resultCount parameter to Sort Response (Amendment 1).
1023 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1025 Support for SRW 1.0 over HTTP. This is an optional feature and
1026 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1029 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1030 on the same port. SRW SearchRetrieveRequests are mapped
1031 to bend_init,bend_search,bend_fetch,bend_close.
1033 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1035 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1036 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1038 ZOOM connections are SRW based if schem http is used for hostname
1039 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1040 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1042 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1043 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1044 distance=n, order=true/false, relation=le, prox unit=word. If
1045 n is omitted, distance 1 is used.
1047 Fixed problem with C compiler include path in wrong order.
1049 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1050 on Solaris. Patch from Ko van der Sloot.
1052 New MARC decode API. All new functions operate on a yaz_marc_t
1053 handle. The most important new functions are: yaz_marc_create,
1054 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1055 decode and destroy respectively. Decoder can produce formats
1056 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1057 include/yaz/marcdisp.h.
1059 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1060 to UTF-8, UCS-32, wchar_t or Latin-1.
1062 * Prototypes for yaz_iconv_-functions moved to separate header
1063 include/yaz/yaz-iconv.h.
1065 Make a few private functions 'static' in unix.c. This prevents
1066 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1068 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1069 are set when Init Response is received.
1071 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1072 but returns diagnostic set as well.
1074 New function yaz_strerror which is a portable wrapper for
1075 strerror/strerror_r/GetLastMessage.
1077 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1078 is returned for MARC. If type is "oai", then OAI MARC is returned.
1080 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1083 --- 1.9.2 2002/11/26
1085 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1087 Fix bad race conditions on SIGTERM and terminate gracefully in
1090 Move retrieval (data1) module to Zebra since nobody seems to be
1093 Add GRS-1 render for ZOOM using same format as yaz-client.
1095 --- 1.9.1 2002/10/05
1097 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1099 Fix broken ESpec handling in data1 module.
1101 SGML reader parses comments and makes them part of the data1 tree.
1103 Added several type casts so that YAZ compiles as C++ code.
1105 ZOOM didn't handle PDU encoding failures properly.
1107 Added more Bib-1 diagnostics (approved extensions).
1109 GNU configure: better check for iconv.
1111 More portable use of accept, getpeername. Check for socklen_t. Use
1112 int/size_t if socklen_t is not defined.
1116 PQF parser rejects bad queries - including those with extra
1117 characters in them. PQF parser used to silently ignore that.
1118 Cleaner API for PQF added, which allows you to get detailed
1119 error information for bad queries (see yaz/pquery.h).
1121 Fixed bug in ZOOM_record_get for type "database".
1123 Implemented mini iconv library supporting conversions between
1124 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1126 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1128 --- 1.8.9 2002/08/20
1130 Fixed ZOOM C record cache so that preferredRecordSyntax and
1131 elementSetName is used to check for already fetched records.
1133 --- 1.8.8 2002/08/02
1135 Added three members in bend_initrequest structure to facilitate
1136 character set negotiation.
1138 Fixed a bug in frontend server that could cause indefinite
1139 loops under rare conditions.
1141 Revised character set utilities (charneg.h) so that encoding
1142 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1144 For PQF, directive @term <type> sets term type for Scan/Search.
1145 Here <type> is general, string, numeric, null. The term type
1146 is inherited - just like @attr.
1148 New call odr_set_charset that sets character set conversion for
1149 international-strings on a ODR stream. Prototype is:
1150 int odr_set_charset(ODR o, const char *to, const char *from);
1151 The InternationalString is still represented as C string in YAZ
1152 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1153 won't). On the protocol level, you can use any encoding.
1155 Support for UNIX sockets in ZOOM.
1157 Solaris recv sometimes returns errno == ENOENT. It is treated as
1158 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1160 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1161 both client and server. Code by Morten Bøgeskov.
1163 --- 1.8.7 2002/05/22
1165 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1166 that they can be used directly from Visual Basic. You must recompile
1167 your windows APP if you're using ZOOM.
1169 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1170 Commands "lang" and "charset" sets language and character set respectively.
1171 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1172 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1174 Attributes from multiple CCL fields may be OR'ed rather than merged
1175 using directive "@field or". Fields are still merged by default -
1176 equivalent to "@field merge".
1178 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1181 Fixed bug in zget for parameter ExtendedServicesResponse.
1185 --- 1.8.6 2002/03/25
1187 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1189 Client displays USR.1:SearchResult-1 (hits per term).
1191 Additional Search Info for search in Generic Frontend Server.
1193 Fixed CCL parsing of "field=s".
1195 WIN32 installer - using the excellent NSIS software from nullsoft.
1197 Fixed CCL parsing of "field = - <number>".
1199 Added function yaz_marc_decode that decodes MARC for line mode
1200 display or XML (similar to that used by JZKit).
1202 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1203 Z39.50. But ISO/ILL was, however.
1205 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1206 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1208 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1209 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1211 --- 1.8.5 2002/02/03
1213 New YAZ client features: Command completion and new commands:
1214 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1215 Code provided by Jacob Poulsen.
1217 New call oid_trav, that visits all registered OIDs via callback.
1219 Function ZOOM_record_get now returns const char pointer rather than
1220 void pointer. It saves a lot of type casts.
1222 For YAZ client, command "auth" now allows you to set authentication
1223 in IdPass style. It is enabled when three tokens are given - order
1224 is user, group and password.
1226 Fix memory leaks in MARC record handling for ZOOM.
1228 New option for YAZ client, -k <kilobytes> that sets
1229 maximum record size. Similar to -k option for generic frontend
1230 server and yaz-ztest.
1232 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1234 Prefix query parser reports "fail" when bad attribute set is given.
1236 Fix in MARC decoder. Proximity logging. Fix for attribute set
1237 in scan handler for server. Patches by Shigeru Ishida.
1239 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1242 Configure option --with-openssl=<dir> now works when a directory is
1243 specified. Patch provided by Morten Bøgeskov.
1245 New option for YAZ client, -u <auth>, that sets authentication.
1247 ZOOM fix: error information was sometimes "missing", since error
1248 was cleared/reset too when it shouldn't.
1250 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1252 --- 1.8.4 2002/01/04
1254 Scan for ZOOM API. New object ZOOM_scanset. New functions
1255 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1256 ZOOM_scanset_destroy.
1258 New ZOOM function, ZOOM_connection_last_event, that returns type
1259 of last event (such as "receive data", "send data", "apdu received",
1262 New ZOOM option, schema, that specifies schema for retrieval.
1264 New CCL feature. Qualifiers can be aliases for one or more
1265 other qualifiers (if more than one is given, OR is used).
1267 ZOOM uses named result sets if target supports it.
1269 Two new YAZ client commands: . (dot, which sources a script of YAZ
1270 client commands), and ! (to execute shell command.). Implemented
1273 Working on Debian packages.
1275 --- 1.8.3 2001/11/19
1277 YAZ client enables named result sets only if target supports it.
1279 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1281 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1282 with key="host" to get same result.
1284 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1285 Function Z3950_resultset_record(s) returns references to records
1286 "owned" by resultset. To become owner use Z3950_record_clone.
1288 Function z_ext_record handles Extended Services. Thanks to
1291 --- 1.8.2 2001/11/12
1293 CCL Parser fix: ignore token comma when dealing with and-lists.
1295 Documentation updates for COMSTACK.
1297 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1298 Changed prototype Z3950_records. For some functions, int parameters
1299 were changed to size_t.
1301 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1304 New MARC decode/display function, marc_display_exl, which properly rejects
1305 non-ISO2709 records. YAZ client uses it.
1307 --- 1.8.1 2001/10/29
1309 Fix bug: local attribute set wasn't set correctly in PQF strings.
1313 * Old Z39.50 codecs no longer supported.
1315 Added ZOOM C binding. See http://zoom.z3950.org/
1317 Renamed states for COMSTACKs to avoid confusion with events.
1319 Implemented cs_look and proper cs_rcvconnect.
1321 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1323 Configure detects POSIX threads on OpenBSD.
1325 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1326 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1328 When error is returned from present handler, non-surrogate diagnostic
1329 is returned in present response (and fetch handler is no longer called).
1331 * Minor adjustments to pquery parser (PQF). Token characters may be
1332 escaped by using backslash (C-style).
1334 PQF parser allows string attribute values to be specified. For @attr,
1335 non-numeric characters after the equal-sign are treated as strings
1336 (e.g. @attr 9=title).
1338 CCL trunction character may be defined (@truncation in file)
1340 * function zget_ExtendedServicesRequest sets waitAction to
1341 waitIfPossible (was wait).
1343 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1346 CCL operator names may be set in field definition files (CCL_bibset).
1347 See ccl/bib1 for an example.
1349 Fixes in ASN.1 compiler for C++ compatibility.
1351 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1352 and "op_or" to avoid conflict with C++.
1354 Fixed problem with GNU readline detection on Redhat 7.0.
1356 Added step-size for Scan backend handler.
1358 Fixed bug that made the frontend server crash when no attribute
1359 set was specified for scan.
1361 Front-end server automatically switches to original working directory
1362 when installed as an NT service. Previously -w had to be specified to
1365 Added extended attributes for retrieval module (data1), so that data1
1366 records carry d1_readXML/SGML attributes. d1_read also supports
1367 null-data rules ( <tag/>)
1369 On UNIX when POSIX threads are available, a separate library libyazthread
1370 is created. Programmers should link with that library and the yaz library
1371 when using threads. The reason for the split was that some applications
1372 on Linux, such as Apache, doesn't work well when using shared objects that
1375 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1376 (or any frontend server) in SSL mode by specifying ssl: followed by
1377 address. Only tested on UNIX.
1379 Added feature for CCL module. Virtual structure s=al or s=ol generates
1380 and-list and or-list respectively instead of phrase search.
1384 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1385 log_mask_str. This was done to avoid name conflicts with other libraries
1386 (such as other PHP extensions).
1388 Added raw OID member for preferred record syntax (request_format_raw)
1389 and returned record syntax (output_format_raw) for backend fetch method.
1391 Config file yaz-config now accepts options so that it returns specific
1392 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1394 Shared library support for UNIX using GNU libtool.
1396 * Modified backend interface. Request/Response struct's replaced by
1397 one read/write C struct. For example bend_fetchrequest and
1398 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1399 Every handler - even search has to be registered in bend_init
1400 handler. This means that the YAZ library no longer refers to
1401 external functions and it makes it possible to make the whole
1402 thing a single DLL/SO.
1404 Added Segment handler for backend server.
1406 Added Zmbol/Zebra administrative functions to YAZ client.
1408 Threaded frontend server on UNIX (when POSIX Threads are available).
1409 Starting the server with option -T enables multi-threading.
1413 Added configure option --enable-comp/disable-comp to control use
1414 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1415 located in sub directory asn.
1417 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1418 in ${exec_prefix}/bin along with the other programs yaz-client and
1421 GNU automake used to maintain makefiles.
1423 Added several OID's.
1425 Changed retrieval module so that we can load records with no abstract
1426 syntax defined. Tagpaths in these records are fully composed of string
1429 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1433 On UNIX, the generated makefile now supports a proper 'make install'.
1434 The prefix can be set via GNU configure to set the install location
1435 (default is /usr/local).
1437 * YAZ programs client and ztest were renamed to yaz-client and
1438 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1439 locations, such as /usr/bin,/usr/local/bin,etc.
1441 * YAZ Header files were moved from include to include/yaz. YAZ Header
1442 files are referred to as include <yaz/log.h> rather than <log.h>.
1443 The YAZ include path (-I ..) is therefore the same as before. Programmers
1444 should update their #include statements or use -Ipath/include/yaz
1445 instead. The main motivation for doing this change is that YAZ header files
1446 can be installed in "standard" locations /usr/include,/usr/local/include
1447 without introducing conflicts, since ALL YAZ header files are stored
1448 in subdirectory yaz (under /usr/include for example).
1450 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1451 rather than project/workspace files. We switched because project files
1452 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1455 Changed name of logging function, logf, to yaz_log, to prevent name
1456 clash with some math-log functions. The YAZ header log.h defines logf
1457 to yaz_log (#define) so there should be no incompatibilities by this
1460 Added bend_start/bend_stop handlers for server. These handler are
1461 called on start/stop of server. For windows they are called whenever
1462 a service is started/stopped.
1464 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1465 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1466 in util/yc.tcl. The auto-generated C code structures are, in a few
1467 cases, incompatible with the old decoders. There are differences in the
1468 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1469 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1470 The preprocessor variable ASN_COMPILED is defined when the compiled
1471 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1472 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1473 wish to use the old encoders/decoders you can specify --disable-yc
1476 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1477 version so that it supports both new - and old version of DB Update
1479 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1480 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1481 change. The name parameter can be set to 0 in which no name is specified
1482 for the construction. The macros odr_implicit and odr_explicit sets name
1483 parameter to zero for the construction involved. New macros
1484 odr_implicit_tag and odr_explicit_tag are similar to the others,
1485 except that a name parameter is added. For programmers' that don't use
1486 ODR they probably only need to change the call to z_APDU and z_External.
1488 Added access control facility by interfacing the TCP wrapper library.
1489 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1490 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1491 name of the daemon and enables the access control as specified in
1492 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1494 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1495 den Dool <H.M.vdnDool@kub.nl>.
1497 Added reference ID parameter to most functions in server API - refer
1498 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1500 Changed name of ccl library to libccl.a (was ccl.a).
1502 Fixed bug in decoder for Explain (Category TargetInfo).
1504 Added support for GNU readline in client. Thanks to Jacob Poulsen
1505 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1507 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1508 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1509 IMPLEMENTATION! This change was made to the development version before
1510 the ZIG decided to retract the amendment. If any users MUST be
1511 compatible with the original Update definition, PLEASE CONTACT US, and
1512 we will include a separate definition corresponding to the old Update
1513 ES. Note that because of the change to the ASN.1 of the
1514 TaskPackageRecordStructure we cannot define a single structure that
1515 will support both versions.
1517 * Added const modifier to buffer parameter for some ODR/BER encoding
1518 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1519 completeWAIS, odr_dumpBER.
1521 Fixed bug in client.c which caused a crash when a scanResponse didn't
1522 contain positionOfTerm.
1524 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1525 * will cause an error in a client if a non-YAZ target sends both a
1526 * list of Scan entries and non-surrogate diagnostics.
1528 Retrieval module enhancements. Tag sets may be typed in the reference
1529 to it. From the .abs-file the "tagset" directive takes a third optional
1530 integer type for the tag set referenced. From a .tag-file the "include"
1531 directive takes a third optional type as well. The old "type" directive
1532 in the tag set itself is still recognized but acts as the default type
1535 Backend interface change. Individual Scan terms returned from bend_scan
1536 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1537 in include/backend.h.
1539 Retrieval module enhancements. Multiple tag sets and attribute sets may
1540 be specified in abstract syntax specs. Revised the error/warning for
1541 logging messages reported by the retrieval module when reading the
1544 Object Identifier system (oid_..) changed. The API is backwards
1545 compatible but the oid-routines now allocates new OID's when needed.
1546 Raw OID's may be specified in oid_getvalbyname.
1548 YAZ now uses GNU configure to generate Makefile(s).
1550 * Minor changes in some of the member names of DeleteResultSetRequest and
1551 DeleteResultSetResponse. See include/proto.h.
1553 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1554 and added member 'languages' in TargetInfo (which was missing).
1556 Changed the way attribute sets are handled in the retrieval
1557 module. These are now cached, just like the abstract syntaxes
1560 Changed YAZ so that it links with compiled ASN.1.
1562 Added Explain-schema definitions and mapping routines. The following
1563 Explain categories have been implemented: AttributeDetails,
1564 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1566 Fixed minor bug in Windows version of Server Library.
1568 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1570 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1572 Added EXTERNAL: UNIverse Resource Report (non-standard).
1574 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1575 ENUMERATED and SET OF.
1577 * Added 'const' to some of the char pointer arguments for the
1578 functions, data1_read_node, data1_getelementbytagname,
1579 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1582 Fixed bug in data1_insert_taggeddata - the last_child member of
1583 parent wasn't initialised.
1585 * Changed data1_read_record and data1_read_node so that the supplied
1586 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1587 doesn't refer to any parts of the "SGML"-buffer.
1589 Fixed bug in server library (Windows version of statserv_remove).
1591 * Changed code so that it compiles as C++. The type definition
1592 of Odr_fun which is a member of Odr_arm was changed. The result is,
1593 that an explicit typecast is needed for the fun pointer when
1594 using Odr_arm - as in:
1595 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1597 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1599 Implemented the new structured date and time definition as approved
1600 by the ZIG. Added schemaId element to the specificTag in Espec-1
1601 (also approved at the last ZIG). Thanks to RVDM.
1603 Added some Object identifiers (RVDM).
1605 Changed the Update Extended Service (RVDM).
1607 Added command "refid" to client which specifies referenceId for
1608 the following requests.
1610 Implemented extended service handling for server. See ztest.c
1611 for an example as well as backend.h. New handlers are registerd
1612 in the Init handler.
1614 * Changed interface for sort in server.
1616 Added new members to statserv_options_block. It allows a server
1617 to read options from another source than just the command line. Thanks
1618 to Charles Woodfield.
1620 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1621 renamed to zboolean. Some C++ compilers complained about the name.
1623 Minor changes to gils.abs. Added index 's' (sort) on title
1624 and date/time-last-modified.
1626 --- 1.4pl2 1998/1/30
1628 Fixed bug in server library regarding inetd mode (-i). This bug
1629 was introduced by release 1.4.
1631 --- 1.4pl1 1998/1/29
1633 Added sort facility in client and backend server interface.
1635 Fixed problem with dependencies in Makefile(s).
1637 Fixed bugs for encoders/decoders of extended services and
1640 Implemented sub-tree feature for schemas. Sub-trees are
1641 referenced in *.abs-files. See explain.abs for an example
1642 of the use of this feature.
1644 Modified bib1.att; local attributes for ANY didn't include
1645 ANY itself (only affects use of the retrieval module).
1647 Fixed bug in plain SGML reader in function data1_read_node:
1648 tags with prefix "var" was incorrectly interpreted as variants.
1650 Added feature "sub-schemas" to enable references to - and definitions
1651 of - group of elements.
1653 * Removed member parent from type data1_element (in data1.h).
1655 Implemented function odr_nullval() that returns the value of
1658 * Removed member num_children from data1_node (in data1.h).
1660 Made NT service interface part of the server library. The
1661 function statserv_main uses the NT service when required and
1662 calls the statserv_start / statserv_close routines.
1664 Routine zget_SearchRequest and zget_PresentRequest fills
1665 resultSetName/Id member with "default" instead of "Default".
1667 Fixed memory leak in server. Request queue member wasn't freed.
1669 Fixed nmem_exit so that memory is freed.
1673 Revised the CCL parser utility to be thread safe.
1675 Added function, oid_ent_to_oid, to replace the function
1676 oid_getoidbyent, which is not thread safe.
1678 * Added nmem_init and nmem_exit to initialize and release
1679 NMEM resources. Function nmem_init should be called once in the
1680 initial thread before NMEM/ODR is used. statserv.c and client.c
1681 have been changed accordingly. The change was necessary to make
1682 NMEM thread safe. The NMEM memory pool is shared amongst threads
1683 in a process. Unix-based applications will still work fine without
1686 Added NT Services interface for the the Z39.50 (statserv) Server.
1687 Refer to the ztest.c source on the usage.
1689 Windows 95/NT port using MSVC5.0. Project files are included in the
1692 * Defined new 'global' handle for the retrieval (data1) system. The
1693 new handled, data1_handle, describes the state of the data1 system.
1694 This handle is passed as first argument to virtually all
1695 data1 related routines. The functions data1_create and data1_destroy
1696 creates and destroys a data1 handle respectively.
1698 Added ODR encode stream member to all backend request structures
1699 init, search, scan etc. This stream should be used to allocate all
1700 memory used for the response when thread safe operation is needed.
1702 Changed the comstack utility, cs_addstr, to be thread safe. The
1703 returned hostname string returned by the function is now part the
1706 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1707 function. The cs_straddr takes a COMSTACK handle as argument, so this
1708 function must be used after cs_create and before bind/connect.
1709 This function is thread safe.
1711 Moved test server to 'ztest' directory - generic server code still
1712 in 'server' directory.
1714 Made prefix query (pquery.c) utility thread safe.
1716 Added new function modifier YAZ_EXPORT to 'export' public DLL
1717 functions when using windows (see include/yconfig.h).
1719 Added definitions to the OID database (util/oid.c) (RVDM).
1721 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1723 Added call to ccl_rpn_delete in client program.
1725 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1726 release of RPN structure.
1728 Added support for C++, headers uses extern "C" for public definitions.
1729 With input from RVDM.
1731 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1732 Thanks to Ronald van der Meer (RVDM).
1734 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1736 Added support for private extensions to the OID database
1737 (oid_setprivateoids()). Thanks to RVDM.
1739 Added optional, physical ANY (key replication)
1741 Fixed null-reference problem in GRS-1 output filter.
1743 Proximity operator added to Prefix Query Format (PQF).
1745 In test client command "base" accepts multiple databases.
1747 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1751 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1753 Smallish bug-fixes in the new encoders/decoders (explain).
1755 Bug fixed in DeleteRequest.
1757 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1759 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1761 Added SOIF syntax (using private OID for now) to retrieval module and client.
1763 Added Update extended service.
1765 Added SearchResult-1 additional info structure.
1767 Added optional CCL (ISO8777) interpreter as separate module. Available
1770 --- 1.2 1996/6/10 (1st anniversary release)
1772 Added Summary record syntax. Lightly tested.
1774 Added OPAC record syntax. Untested.
1776 Added ResourceReport service encoders/decoders. Untested.
1778 Fixed bug in z_Unit - wrong tagging on unitSystem.
1780 Fixed bug in the DiagRecs decoder.
1782 Added options for max PDU size and session timeout to frontend-server.
1784 Added documentation of query-language parsers and other supporting utilities.
1786 [frontend-server] Added Attribute set to the bend_scanrequest API.
1788 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1789 surrogate diagnostics were generated.
1791 [retrieval] Allow multiple local values for attribute.
1793 [retrieval] Allow multiple attributes per element in .abs files. index type.
1795 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1797 --- 1.1pl2 1996/4/10
1799 Minor changes, mostly specific to Zebra's requirements (retrieval)
1803 Repaired bug in frontend server when running multiple listening
1804 endpoints in dynamic mode.
1806 z_External() now won't break if a known, ASN.1 value comes encapsulated
1807 in an octet-string. The value will pass through unmodified in an Odr_oct.
1809 Added a bit of code to the demo client to decode & display
1810 ASN.1-structured records represented in the octet-aligned branch of
1811 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1813 Added z_ext_getentbyref() to the ASN module. Doc updated.
1815 * Completed the SCAN definition in the ASN module. This may break SCAN
1816 code based on older YAZ-versions at compile-time. The fix is easy -
1819 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1820 under the SCAN definition. Remember to initialize this, server-people.
1822 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1823 that this does not extend to ODR and ASN.
1825 Comstack allows insertion of established socket (primarily for
1826 inetd-operation of servers). Doc updated.
1828 Front-end server can now start from the inetd in TCP mode. Doc
1831 --- 1.0pl4 1996/1/24
1835 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1836 the rank and record number.
1838 Adjustments to the frontend server.
1840 Fixed diagnostic BER dumper. It ignored the file argument.
1844 Various changes to retrieval module.
1846 Changed the union discriminators of the protocol files from enums to
1847 ints paired with #defines.
1849 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1852 *Changed operator in the RPN structure to 'roperator', again to avoid a
1855 Fixed problems in Explain decoders/encoders.
1857 --- 1.0pl2 1995/12/6
1859 Memory bug in log module fixed.
1861 --- 1.0pl1 1995/12/5
1863 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1865 Bug in Explain DatabaseInfo module fixed.
1867 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1871 The shift to v1.0 signals that we now consider the *core* functionality
1872 of YAZ reasonably stable (the core being more or less equivalent to
1873 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1874 tested (Explain not at all - though that will happen soonish).
1876 Minor changes to code to support Windows port.
1878 Various minor changes after we're getting to use GRS-1 & co. more.
1880 Added Espec-1 format.
1882 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1883 of the protocol and it cannot be selected when encoding (maps into 'string'
1884 when decoding). Needed to talk to some servers.
1886 Demo client can request simple element set names.
1888 Added Diagnostic Format encoders/decoders.
1890 Added simple Close handling to frontend server (no hooks for resource
1891 reporting yet), and demonstration client.
1893 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1895 --- 1.0b3 1995/08/24
1897 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1898 handled incorrectly when records were requested in the searchResponse. This
1899 will only affect you if you use the frontend-server.
1901 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1902 Test-client will ask for and print GRS1. Ztest will return dummy records
1905 Added Explain encoders/decoders to the service-level API. Untested.
1907 Added Extended Services: Item Order encoders and decoders to the Service-
1908 level API. Untested. We could use a recent copy of the pertinent bits
1909 of the ILL protocol to add those bits.
1911 Added diagnostic format 1 encoders/decoders to the service-level API.
1914 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1915 odr_cons.c, which causes a more correct output.
1917 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1918 was always set to 0 when no records were requested in the searchRequest.
1920 * Added better external-handling. This shouldn't harm old code that
1921 *encodes* externals. It can break code that looks for a
1922 'single-ASN1-type' representation, since those types that are known
1923 are now decoded immediately. Look at the SUTRS sample code in
1924 seshigh.c and client.c. Documentation updated.
1926 Handling of structured records in bend_fetchresponse. Length -1 marks
1927 structured record, type is deduced from format field.
1929 --- 1.0b2 1995/06/27
1930 Fairly quick maintenance release to add SUTRS support.
1932 Fixed handling of SUTRS records in the demonstration client.
1934 * Added format field to the bend_fetchrequest and bend_fetchresponce
1935 structures of the backend API (frontend server). When the record is
1936 returned, the value of the format field is mapped to an OID. The
1937 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1938 of the record. The special value VAL_NONE in the bend_request means
1939 that no specific format was requested by the client. Documentation
1940 updated accordingly. Test server (ztest) will return a fixed dummy
1941 SUTRS record if your client requests SUTRS.
1943 Documentation updated accordingly.
1945 You can now set external libraries and RANLIB support in the top-level
1949 First public release.
