1 Added GFS utility function bend_assoc_is_alive which returns 1 if
2 association is still alive (client is connected); 0 otherwise (client
3 closed connection). This allows busy servers to stop working for
6 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
8 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
9 Client code may now interrogate options such as "init_opt_sort" to
10 find out whether the server claims to support various options.
14 Added utilities yaz_{set,get}_esn to set/get element set name from
17 Removed the build of libyazthread.la. The libyaz.so is the threaded version
18 of YAZ and has been so since YAZ 2.1.10.
20 Implemented ZOOM_record_error which returns error information for
21 record (surrogate diagnostic).
25 Updates for SRU Update by Ko van der Sloot:
26 1. Changed name from "operation" to "action"
27 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
28 versions in the code, marked as 'backward compatible'.
29 3. Added diagnostics for SRU Update.
31 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
33 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
35 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
37 For GFS, fixed problem with SRU diagnostic 'First record position out of
38 range' being issued for 0 hits.
40 zoomtst10 part of Windows Build.
44 Implemented yaz_filepath_comp which splits a path into file path
45 components (required by Zebra 2.0.3+).
47 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
48 BSD inspired license until now so this should not have any real impact on
49 anybody. See http://www.opensource.org/licenses/bsd-license.php
51 Fixed bug #687: Missing log lines.
53 Fixed bug #678: CQL to PQF translation does not preserve double-quote
56 Fixed bug #689: SRU diagnostics to be added.
58 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
59 whether a connection is idle (no more work do do).
63 Change type of optval from long to int for invocation of setsockopt with
64 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
66 Added support for specifying the max log file size for the Generic
67 Frontend Server. The size is given with option -r.
71 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
75 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
78 Fixed bug in Generic Frontend Server that could cause a server to stop
79 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
81 For the generic frontend server, the maximum record size is used as maximum
82 size of incoming packages (SRU + Z39.50). The value until was previously
83 only used in Z39.50 Init negotiation and, later, in a session controlled
84 sizes of records returned. This is controlled using -k option. It can be
85 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
89 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
92 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
94 New option for yaz-marcdump -lpos=value which allows setting a portion
95 of MARC header to a certain value.
97 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
99 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
100 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
102 --- 2.1.26 2006/08/15
104 Fixed problem with SRU mode type (soap, get, post) for yaz-client
107 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
109 --- 2.1.24 2006/08/08
111 Fixed MARC ISO2709 encoding routines to deal with character set
114 Minor changes to GFS logging. Database included in search request log
117 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
118 cached/multiple records.
120 Shared libraries are built by default on Unix+configure.
122 Changed cql2pqf transformation to use a different evaluation order. The
123 new order is: always, relation, structure, position, truncation, index
124 and relationModifier. Old order was: always, relation, relationModifier,
125 structure, index, position, truncation. Note that the the latter ones
126 override former ones for identical attributes.. The new scheme means that
127 it is possible to override any existing attribute with a relationModifier.
128 And also that it is possible to override everything for the index rule
129 (except the ones listed in relationModifier). No order is perfect but this
130 one, we believe, covers more real cases.. The "always" should have been
131 called "default", since the attributes there can be overridden with all
134 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
135 compilation phase, but also for yaz-config --cflags output. This allows
136 us to have public headers with Libxml2 stuff in them . It should also,
137 eventually, make Libxml2 checks redundant in packages using YAZ, such
140 --- 2.1.22 2006/06/15
142 Changed SRU update structure bend_update_rr so that SRU diagnostics are
143 stored in uri, message and details.. Previously diagnostics were stored
144 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
145 compatibility.. but he's probably the only one affected, so.
147 Added support for CCL, compiled on the client side, in ZOOM-C. This
148 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
149 input; the resulting query objects can be used for for searching with
150 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
152 YAZ' configure searches for OpenSSL by default.
154 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
155 SL_CTX_use_certificate_file. See
156 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
157 for more info. Thanks to Ko van der Sloot.
159 --- 2.1.20 2006/06/02
161 Bug #600: SRU GET, POST support for yaz-client. Introduced
162 command 'sru' which selects method SOAP/GET/POST.
164 Allow missingValueAction to be specified for the sortspec string -
165 function yaz_sort_spec. By default, the missing value action is null.
166 Use ! to specify "abort". Use = followed by stringvalue to specify default
169 Ensured that Present-handler (if defined) is called in GFS before any call to
170 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
171 searchRetrieve requests.
173 Documentation for YAZ is now based on the Docbook XML/XSLT using
174 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
175 is no longer depending on jade/openjade or docbook-to-man scripts.
176 PDF is no longer part of the distribution - but can optionally be
177 made using DSSSL/jadetex or FOP.
179 Added retrieval handling support in Generic Frontend Server to support
180 conversion between MARC/XML as well as XSLTtransforms. See
181 etc/yazgfs.xml for an example.
183 Added Authentication support to Generic Frontend Server in SRU
184 mode. Authentication using HTTP Basic is supported, as is the use
185 of 'x-username' and 'x-password' parameters in the request itself.
187 Added support for a new character set MARC8s identical to MARC8 except
188 that it converts combined characters to single Unicode characters in the
189 Latin-1 range (when possible).
191 --- 2.1.18 2006/04/24
193 ASN.1 compiler 0.4: generates brief Doxygen file header for
194 generated .h/.c files.
196 Utility yaz_iconv now supports conversion to MARC-8.
198 New facilities for the MARC module. The reading - and writing of
199 content are separate methods for the yaz_marc_t handle. The following
200 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
201 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
202 format). Write functions have prefix yaz_marc_write_.. The existing
203 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
204 available. Removed support for OAI-MARC and simplexml (not the
205 simplexml from PHP5).
207 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
208 to be returned for this connection.
210 --- 2.1.16 2006/03/31
212 Allow multiple languages and charsets to be specified with
213 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
214 negcharset iso-8859-1,utf-8
216 Translation of proximity nodes from CQL into PQF now works.
218 Moved to automake 1.8, 1.9.
220 Added function yaz_log_set_handler which allows a log handler to be
221 installed. This handler will be called for all log messages. Output
222 to file is also produced; but that can be disabled by passing NULL
223 fname to yaz_log_init_file.
225 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
227 For SRW (including GFS), accept application/soap+xml as content-type
230 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
231 produces NO stylesheet reference even if a default stylesheet is specified
234 --- 2.1.14 2006/03/14
236 Updated Windows package to include yazd.dll + yazd.lib for the
237 Development component.
239 If the environment variable YAZ_LOG is set, then it is used as a
240 string indicating the default level of logging to use if not
241 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
242 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
243 used as before. So, for example, to omit warnings from YAZ logging,
246 cql_transform() now map structure and other attributes before indexes,
247 so that index-specific structures and other attributes can override
248 defaults. So now a combination of mapping specifications such as:
250 index.dc.date = 1=date-modified 4=5
251 does the right thing.
253 cql_transform() now also respects the "always" mapping specification,
254 which establishes an initial set of attributes to be used for all
255 terms except where overridden by more specific attributes associated
256 with the index, relation or modifier.
258 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
259 which mode to use; one of "post", "get" or "soap" (SRW, default).
261 Fixes for yaz_iconv routines: changed trie-based character set conversions
262 to use only non-negative values for bit fields due to Sun's C compiler not
263 supporting negative values.
265 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
266 sequences where not read correctly. Fix by Rustam Usmanov.
268 Updated win/makefile to use options, settings which makes things
269 compile with VS C 2005.
271 --- 2.1.12 2006/02/01
273 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
275 In ZOOM socket code, use select instead of poll on MacOSX.
277 ZOOM-C now support client-side compilation of CQL into RPN that is
278 sent to the server, enabling CQL to be used against all Z39.50
279 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
280 ZOOM_query object, and submit it using ZOOM_connection_search().
281 The CQL-to-RPN translation uses a configuration file, the name of
282 which must be specified in the Connection's "cqlfile" option.
284 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
285 function, which takes as its start-term parameter a ZOOM_query object
286 (which may have had either CQL or RPN set into it).
289 --- 2.1.10 2005/11/29
291 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
292 GFS to support this as well. Backend handler, bend_srw_update, does the
293 update work. Code contributed by Ko van der Sloot.
295 Allow retrieval of Search Result-1 information in ZOOM by the use of
296 options that are attached to a result set. ZOOM documentation updated
299 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
300 UTF-8 conversion. Patch by Raj Patel.
302 Added option -m to GFS to control formatting of timestamps in log file.
304 Added 'exit' as synonym for 'quit' in yaz-client
306 Added support for specifying SRW resultSetId + resultSetIdleTime in a
307 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
308 for the new members. Patch by Ko van der Sloot.
310 Added support for SRU POST. It is supported for content-type
311 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
313 Do not build the separate Multi-threaded (MT) library libyazthread.la.
314 Instead make the library libyaz.la multi-threaded. Threading as a whole
315 can still be disabled by configure option --disable-threads. Previosly,
316 with older GLIBCs there were problems with MT libs under Apache. This
317 has now been fixed a long time ago.
319 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
322 CQL module modified to be case insensitive for relations/indexes/operations.
324 Fixed bug in CQL transform code: incorrect value relationModifieder
327 Added 'show all' command for yaz-client which retrieves all results
330 Added new yaz-client, xmles, which takes a (private) OID and
331 a document to be sent as an extended service request.
333 Describe new yaz-client commands wait_response and set_auto_wait.
335 Increase TCP/IP listener backlog from 3 (which I am guessing was
336 copied from the SunOS manual entry way back when) so SOMAXCONN, so
337 that the socket will queue as many incoming connections as it's able
338 to handle ongoing connections. In other words, it will never now
339 refuse a connection that it would be able to handle merely because
340 it's not got around to accepting() enough of the pending connections
341 yet. This is the behaviour anyway under Linux, where the listen()
342 argument is ignored; but not under BSD and on systems such as
343 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
344 YAZ-based servers should now be uniform across operating systems in
347 yaz-marcdump uses 64-bit file access on some systems. This is enabled
348 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
349 This allows yaz-marcdump to read large MARC batches (>2 GB).
351 Modified all YAZ source files - except the source which is auto-generated
352 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
355 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
356 corresponding to the existing *_setl() function. These allow option
357 values containing arbitrary valuues.
359 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
360 ZOOM_resultset_sort() in new applications. Its behaviour is identical
361 except that it returns an indicator of whether or not the sort
362 criterion was accepted (0 for OK, -1 for invalid).
366 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
367 MARC output rather than returning "new" buffer.
369 yaz-client warns about unknown init options.
371 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
375 Added support for SRW sort in Generic Frontend Server. Patch
376 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
377 sortKeys - or NULL if none is provided.
379 Fixed bug #307: It was impossible to specify indefinite/no timeout
380 for ZOOM_event. Special timeout value -1 now means indefinite timeout
383 Added support for multiple languages and charsets to be specified in
384 ZOOM. Each charset/language is separated by a blank. If negotiation is
385 in effect in init-response, Option
386 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
387 Code based on patch by Vasiliy Osadchuk.
389 Fixed bug #306: infinite recursion that occurred when calling
390 yaz_log_level_init as the first call (before other log level or
393 Fixed bug in scan handling in front end server: if preferred-Position-In-
394 Response was non-present, a NULL pointer referece was performed.
398 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
399 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
400 now defined for all those error codes. So instead of putting 109 in
401 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
402 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
404 Modified the yaz-marcdump utility to skip garbage bytes between MARC
407 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
409 Program yaz-client now exits and produces an error message if multiple
410 Z39.50 servers are specified on the command line (none or one allowed
413 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
418 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
420 Fixed bug #272: Preserve spacing for CCL terms.
424 Added support for virtual hosts and multiple backend servers for
425 the YAZ frontend server. The configution is XML based and
426 support specificition of CQL to RPN mappings and explain information.
427 See section "Virtual Hosts" in the YAZ manual.
429 Extended OPAC display utility. OPAC display utility renders
430 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
431 to supplement yaz_marc_decode_wrbuf.
433 Fixed a bug in MARC decoder that could caused it to crash for some
434 invalid MARC records. More diagnostics and warnings where added in
435 XML output (warnings, etc are stored in comments).
437 --- 2.0.34 2005/02/08
439 Fixes for UNIX domain sockets. Bug #261.
441 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
443 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
444 Added yaz_marc_subfield_str which defines subfield lead string which is
445 used in YAZ_MARC_LINE format. Default string is blank+$. Added
446 yaz_marc_endline_str which defines end of fields string used in
447 YAZ_MARC_LINE format. Default string is newline.
449 Experimental support for MarcXChange. This format can be produced
450 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
451 http://www.bs.dk/standards/MarcXchange.xsd
453 Added yaz-client commands scansize that sets maximum number of
454 entries to be returned by scan.
456 --- 2.0.32 2005/01/11
458 Added support for SRW scan in yaz-client and Generic Frontend Server.
460 * Added whereInList member to SRW Scan Term.
462 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
464 Fixed NMEM system to return aligned blocks on the smallest boundaries
465 that are suitably aligned for all possible types on the particular
466 architecture YAZ is being built for.
468 --- 2.0.30 2005/01/04
470 Fixed numerious warnings that was issued with newer versions of GCC.
472 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
473 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
476 Make YAZ Generic Frontend Server slightly faster.
478 Enhance (and reduce) logging for Generic Frontend Server.
480 Revert YAZ log system so that it flushes every write operation
481 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
483 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
484 instead of LOG_, due to name clash with syslog(3). LOG_ are still
485 present. New applications should define YAZ_USE_NEW_LOG=1 - this
486 will effectively disable old definitions.
488 --- 2.0.28 2004/11/09
490 Added yaz_log_time_format which specifies log format using
493 Added yaz_log_module_level which returns mask for a module. Value
494 is non-zero mask a if module is enabled; zero if disabled.
496 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
497 in include/yaz/cql.h.
499 Fixed bug #176: Dont throw diagnostics on empty SRU args.
501 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
503 Fixed bug #172: RPM builds does not enable SSL.
505 Doxyfile.in part of dist. Doxyfile generated by configure.
507 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
508 are given and the corresponding component does not exist.
510 Extend CCL documentation in YAZ reference. Describe r=r.
512 --- 2.0.26 2004/10/01
514 Fixed MARC->MARCXML conversion to properly deal with
515 fields, subfields, indicators having non-ASCII characters.
517 Fixed MARC->MARCXML conversion so that ASCII control characters
518 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
521 Added YAZ GFS support for conversion from Z39.50 surrogate
522 diagnostics to SRW surrogate diagnostics.
524 Bug fix: YAZ GFS did not return schema in explainResponse.
526 --- 2.0.25 2004/09/30
528 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
529 now converts recordSchema to elementSetName as well as schema URI.
531 Fixed bug in COMSTACK that prevented HTTP request packages from being
534 --- 2.0.24 2004/09/29
536 Added CCL facility r=r "range" which is similar to r=o "ordered" but
537 does not require white-space before and after the dash in a range, e.g.
538 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
541 Fixed a few AC_TRY_LINK configure tests that did not operate properly
542 due to new GCC removing "redundant" code.
544 Added yaz-client commands scanpos and scanstep that sets preferred
545 position and step-size for scan.
547 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
549 Added CCL utility ccl_qual_buf which parses one or more CCL
550 spec lines in a buffer.
552 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
553 of name and value - ignoring empty lines and comments.
555 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
557 Added odr_get_element_path which returns current element path for an
558 ODR handle. This utility is useful in error handling or user-defined
561 Added ODR_PRINT utility odr_set_stream which is is a more generic
562 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
563 to a write function and pointer to close function. The close function - if
564 non-NULL - will be called during odr_destroy.
566 Fixed bug in CCL parser where truncation char was not removed from
567 right side when truncation=both was in effect.
569 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
572 --- 2.0.23 2004/08/11
574 Fix buffer overrun in CQL parser when dealing with proximity (%).
576 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
577 to UTF-8/UCS conversion is now only based on codetables.xml.
579 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
581 --- 2.0.22 2004/08/06
583 Add support for more "commit changes" in ZOOM (uses Extended Services).
585 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
588 Yet another small fix for configure of SSL.
590 --- 2.0.21 2004/05/14
592 Fix SSL libs for configure when --with-openssl=DIR is given.
594 --- 2.0.20 2004/05/10
596 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
598 SSL comstack now uses yaz.pem certificate file on server side
599 by default. Certificate filename can be configured by calling
600 comstack function cs_set_ssl_certificate_file before cs_bind is used.
602 Fix bug regarding multiple calls to ZOOM_connection_connect.
604 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
606 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
607 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
609 ZOOM now allows inspection of X509 peer certificate for verification.
610 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
612 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
613 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
614 as "modular" but it simplifies things.
616 Added cs_get_peer_certificate to that returns peer X509 PEM.
618 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
619 NULL if SSL is unavailable.
621 Documentation about MARC decoding tools.
623 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
625 --- 2.0.19 2004/03/30
627 Rename CHANGELOG to NEWS to follow GNU style packing.
629 Fix bug with missing initialization of member in init_diagnostics.
630 This bug affects threaded version of GFS server.
632 --- 2.0.18 2004/03/20
634 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
637 Ensure zlib.dll is packed with Windows install.
639 --- 2.0.17 2004/03/17
641 Fix encoding of xsd:string to use text instead of CDATA.
643 Fix endless loop in CQL parser with unbalanced ".
645 Use a more compact way to store MARC-8 conversion tables.
647 --- 2.0.16 2004/03/16 Debian only
649 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
652 Update CQL parser to use new CQL 1.1 modifiers for booleans and
657 --- 2.0.15 2004/03/01
659 Another fix for decoding of XML packed records.
661 --- 2.0.14 2004/02/25
663 Fixes for Chunked encoding. White space not ignored after length spec.
665 Update NS and use default NS for SRW diagnostic elements.
667 --- 2.0.13 2004/02/23
669 Implement ZOOM_resultset_cache_reset which resets record cache.
671 Implement ZOOM_resultset_sort which sorts a result set.
673 Implement chunked HTTP transfer.
675 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
677 --- 2.0.12 2004/02/16
679 Added member 'schema' to bend_explain_rr structure so that backend
680 can specify explain record identifier. Defaults to Zeerex 2.0.
682 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
684 --- 2.0.11 2004/02/16
686 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
689 Added init command for yaz-client which sends "extra" init request.
691 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
692 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
694 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
696 Make ZOOM error code for "invalid query".
698 Fixed compilation for SSL which wasn't properly enabled for all platforms.
700 --- 2.0.10 2004/02/05
702 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
705 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
707 Added option -p <file> to make Generic Frontend Server to write PID file.
709 Added option -D to put Generic Frontend Server in background on its own.
711 Make ZOOM C recognize option "password". If unset, "pass" is used
712 (for backwards compatibility).
714 Fixed a bug in Generic Frontend Server that could make it crash if a
715 client sets characterSetNegotation bit, but didn't pass negotiation stuff
718 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
719 Must be issued before open, in order to be in effect.
721 --- 2.0.9-6 2004/01/12 Debian/Windows
723 Make the SRU server more picky WRT unknown params, etc.
725 Bug fix: ZOOM scan response didn't return displayTerm - when present.
727 New YAZ client command, options, that sets Z39.50 options.
729 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
730 options from a string of tokens (one token for each option bit).
732 Update SRW diagnostic code messages.
734 --- 2.0.9-5 2004/01/07 Debian/Windows
736 Handle user defined stylesheet for SRW/SRU.
738 --- 2.0.9-4 2004/01/06 Debian/Windows
740 Fix bug in decoding of Content-Length.
742 --- 2.0.9-3 2004/01/06 Debian/Windows
744 Fix a bug with decoding of XML packed records.
746 --- 2.0.9-2 2004/01/05 Debian only
748 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
750 Fix bug in SRW/SRU diagnostics decoding.
754 Fixed bug in Generic Frontend Server which could drop records exceeding
755 preferred message size. Reported and fixed by Irina Dijour.
757 Fixed calculation of package size for structured records in Generic
758 Frontend Server. Reported and fixed by Irina Dijour.
760 Fixed namespace for SRW/SRU diagnostics.
762 Fixed SEGV in yaz-client that occured for HTTP connection errors.
766 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
767 this version is incompatible with version 1.0 and older YAZ SRW/SRU
770 CQL changes to reflect recent changes to the specification:
771 * Documentation talks about context sets instead of index sets.
772 * Documentation talks about indexes instead of qualifiers.
773 * The CQL-to-PQF transformer's configuration file now uses
774 "index.set.name = <attributes>" instead of the old form
775 "qualifier.set.name = <attributes>". (Both forms are still
776 understood but the latter is deprecated.)
777 * CQL terms with no explicit index specified are now interpreted as
778 cql.serverChoice instead of srw.serverChoice (which of course
779 behaves exactly the same.)
783 MARC conversion can now generate ISO2709 output in another
784 character set. yaz-marcdump uses this facility if you invoke it
787 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
788 functions from there can be used from C++.
792 Frontend server now transfers memory from decoded packages to stream
795 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
796 references to show up.
798 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
799 the ZOOM Abstract API. The older names for the same options are still
800 also supported for the benefit of old applications.
802 ZOOM-C supports "implementationId" and "implementationVersion" options
803 to go along with "implementationName". These allow the user code to
804 specify identification strings to be sent to servers.
805 Add OID for the new ExtLite attribute set.
807 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
808 as requested/supplid by Ere Maijala <ere@atp.fi>
810 For generic frontend server, reverse the order of
811 "toolkit-supplied / application-supplied" strings sent as implementationId,
812 Name and Version. Also, remove the spaces around the slash. This brings
813 the GFS in line with the behaviour of ZOOM-C on the client side.
815 Add function ZOOM_scanset_display_term.
817 yaz-client shows scan displayTerm if present.
819 Utility yaz-iconv is now installed by default along with the man page
822 Extend configure check for OpenSSL to use pkg-config where available (such
825 Incorporate patch by Morten Bogeskov which allows a Unix file socket
826 server to specify uid/gid/mask for socket using the format
827 unix:[user=uid,][group=gid,][umask=mask,]file=path
828 If file= is omitted the existing format is assumed, e.g.
830 in which case the mask is 0666 (rw for everybody).
832 Major restructure of YAZ source. All source in libyaz is in src directory.
833 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
834 util (utility programs such as ASN.1 compiler, yaz-marcdump).
836 Added man page for utility yaz-marcdump (used to be called marcdump).
837 yaz-marcdump is installed by 'make install'.
839 Fixed a memory leak in Generic Frontend Server that occurred when decoding
840 of incoming package failed.
842 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
844 Change prototype of odr_perror: add const to message string.
846 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
848 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
849 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
850 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
851 DNS lookup. There should not be any compatibility problems with this
852 assuming that blocking=1 or 0 is used.
854 Fix bad reference in UNIX comstack in function cs_addrstr.
856 Fix for compilation on AIX.
858 The generic front-end server (server/seshigh.c) now supports returning
859 Init diagnostics to the client in User-information-field, in
860 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
865 Allow any CQL relation (not just all,any,exact,scr).
867 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
868 that features the same UI.
870 Implemented command update0 in YAZ client which is equivalent to
871 update but uses old of Ext Update ASN.1.
873 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
874 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
875 Previously no OID was used for this info.
877 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
878 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
879 returns 'malformed search term' otherwise.
881 SortResponse member resultCount now set to NULL in sort handler of
884 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
887 Add three new utility functions for translating OIDs between various
888 formats -- symbolic name such as "Usmarc", minus-1-terminated int
889 arrays and dotted strings such as "1.2.840.10003.9.5.1":
890 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
891 char *oid_to_dotstring(const int *oid, char *oidbuf);
892 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
894 Reverted modifications for ES Update definition for z_IU0Update
895 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
896 is back to YAZ 2.0.2.
898 String value attributes for CCL parser.
900 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
901 which their FirstSearch server returns in Init responses, sometimes
902 carrying useful diagnostic information when Init fails. This has the
903 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
904 "z39.50/oclcui.asn", where its definition is somewhat different from
905 what OCLC document on their web-site, as required to interoperate with
908 Support for anonymous authentication in yaz-client. Use the command
911 * Fix the OID of the Index Data-local "admin" Extended Service from
912 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
913 the 1000, which indicates a locally-defined OID, was a mistake.
917 Fix CCL directive @case handling so that it affects string match for
918 both CCL keywords and qualifiers.
920 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
921 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
922 Decoder has been updated with ASN.1 changes as listed in
923 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
924 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
925 z_IUUpdate, remains unchanged.
927 ZOOM_record_get may now return a record in a specific character set.
928 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
929 "from" is the character set of record as returned by target. "to" is
930 the character set to be returned. If omitted, "to" is UTF-8.
932 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
934 New ODR utility, odr_getelement, which returns name of element for
935 which encoding/decoding failed.
937 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
938 in cases where a required element was omitted.
940 Bug fix: some MARC8 sequences were not converted.
942 New ZOOM option "step" which specifies number of records to be
943 retrieved in one chunk. Used in conjunction with "start" and "count".
945 SRW support for yaz-client. Use scheme http: to use it, e.g.
948 yaz-client no longer does (un)intelligent character set conversions
949 by default. Can be enabled with charset and marc_charset commands.
951 xmalloc trace fix for 64-bit systems such as DEC alpha.
953 Solaris 2.6 compile fix.
955 New function, cql_strerror() translates SRW error codes, as returned
956 by cql_transform_error(), into human-readable English strings. Used
957 in yaz-client diagnostics when appropriate.
959 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
960 converts it into a type-1 query which is sent to the server. This
961 makes CQL available for use with all Z-servers, as opposed to the tiny
962 minority that can handle CQL queries themselves.
966 New Debian package layout similar to the Redhat Package layout.
968 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
969 and search result respectively.
973 Redhat package is now several packages: libyaz (runtime libraries),
974 libyaz-devel (development and documentation, and yaz (utility programs).
975 Package spec file by Morten Bøgeskov.
977 New member 'schema' in struct bend_fetch_rr which the name of requested
978 schema (SRW/SRU) for record (or NULL if none was given). The fetch
979 handler MAY set this to reflect the schema of the returned record.
981 New member 'display_term' in struct scan_entry. GFS now sets member entries
982 and allocates scan entries to be filled by user scan handler. In previous
983 version, entries member was allocated by the scan handler. That still works,
984 but the GFS will ignore member display_term - assuming it was NOT set by
985 the handler. The fact that the GFS now allocates the entries both allows
986 for new members and makes a scan handler easier to write.
988 Fix CQL lex buffer overflow.
990 SRW/SRU recordPacking. For SRW default recordPacking is string. For
991 SRU default recordPacking is string.
993 SRU protocol support for frontend server.
995 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
997 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
999 Added scan for the ZOOM shell (zoomsh).
1003 * String Identifers for Schemas (Amendment 5).
1004 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1005 Old definition for schema
1006 Odr_oid *schema; /* OPT */
1011 Z_InternationalString *uri;
1012 #define Z_Schema_oid 1
1013 #define Z_Schema_uri 2
1016 * resultCount parameter to Sort Response (Amendment 1).
1017 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1019 Support for SRW 1.0 over HTTP. This is an optional feature and
1020 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1023 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1024 on the same port. SRW SearchRetrieveRequests are mapped
1025 to bend_init,bend_search,bend_fetch,bend_close.
1027 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1029 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1030 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1032 ZOOM connections are SRW based if schem http is used for hostname
1033 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1034 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1036 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1037 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1038 distance=n, order=true/false, relation=le, prox unit=word. If
1039 n is omitted, distance 1 is used.
1041 Fixed problem with C compiler include path in wrong order.
1043 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1044 on Solaris. Patch from Ko van der Sloot.
1046 New MARC decode API. All new functions operate on a yaz_marc_t
1047 handle. The most important new functions are: yaz_marc_create,
1048 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1049 decode and destroy respectively. Decoder can produce formats
1050 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1051 include/yaz/marcdisp.h.
1053 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1054 to UTF-8, UCS-32, wchar_t or Latin-1.
1056 * Prototypes for yaz_iconv_-functions moved to separate header
1057 include/yaz/yaz-iconv.h.
1059 Make a few private functions 'static' in unix.c. This prevents
1060 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1062 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1063 are set when Init Response is received.
1065 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1066 but returns diagnostic set as well.
1068 New function yaz_strerror which is a portable wrapper for
1069 strerror/strerror_r/GetLastMessage.
1071 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1072 is returned for MARC. If type is "oai", then OAI MARC is returned.
1074 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1077 --- 1.9.2 2002/11/26
1079 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1081 Fix bad race conditions on SIGTERM and terminate gracefully in
1084 Move retrieval (data1) module to Zebra since nobody seems to be
1087 Add GRS-1 render for ZOOM using same format as yaz-client.
1089 --- 1.9.1 2002/10/05
1091 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1093 Fix broken ESpec handling in data1 module.
1095 SGML reader parses comments and makes them part of the data1 tree.
1097 Added several type casts so that YAZ compiles as C++ code.
1099 ZOOM didn't handle PDU encoding failures properly.
1101 Added more Bib-1 diagnostics (approved extensions).
1103 GNU configure: better check for iconv.
1105 More portable use of accept, getpeername. Check for socklen_t. Use
1106 int/size_t if socklen_t is not defined.
1110 PQF parser rejects bad queries - including those with extra
1111 characters in them. PQF parser used to silently ignore that.
1112 Cleaner API for PQF added, which allows you to get detailed
1113 error information for bad queries (see yaz/pquery.h).
1115 Fixed bug in ZOOM_record_get for type "database".
1117 Implemented mini iconv library supporting conversions between
1118 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1120 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1122 --- 1.8.9 2002/08/20
1124 Fixed ZOOM C record cache so that preferredRecordSyntax and
1125 elementSetName is used to check for already fetched records.
1127 --- 1.8.8 2002/08/02
1129 Added three members in bend_initrequest structure to facilitate
1130 character set negotiation.
1132 Fixed a bug in frontend server that could cause indefinite
1133 loops under rare conditions.
1135 Revised character set utilities (charneg.h) so that encoding
1136 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1138 For PQF, directive @term <type> sets term type for Scan/Search.
1139 Here <type> is general, string, numeric, null. The term type
1140 is inherited - just like @attr.
1142 New call odr_set_charset that sets character set conversion for
1143 international-strings on a ODR stream. Prototype is:
1144 int odr_set_charset(ODR o, const char *to, const char *from);
1145 The InternationalString is still represented as C string in YAZ
1146 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1147 won't). On the protocol level, you can use any encoding.
1149 Support for UNIX sockets in ZOOM.
1151 Solaris recv sometimes returns errno == ENOENT. It is treated as
1152 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1154 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1155 both client and server. Code by Morten Bøgeskov.
1157 --- 1.8.7 2002/05/22
1159 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1160 that they can be used directly from Visual Basic. You must recompile
1161 your windows APP if you're using ZOOM.
1163 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1164 Commands "lang" and "charset" sets language and character set respectively.
1165 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1166 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1168 Attributes from multiple CCL fields may be OR'ed rather than merged
1169 using directive "@field or". Fields are still merged by default -
1170 equivalent to "@field merge".
1172 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1175 Fixed bug in zget for parameter ExtendedServicesResponse.
1179 --- 1.8.6 2002/03/25
1181 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1183 Client displays USR.1:SearchResult-1 (hits per term).
1185 Additional Search Info for search in Generic Frontend Server.
1187 Fixed CCL parsing of "field=s".
1189 WIN32 installer - using the excellent NSIS software from nullsoft.
1191 Fixed CCL parsing of "field = - <number>".
1193 Added function yaz_marc_decode that decodes MARC for line mode
1194 display or XML (similar to that used by JZKit).
1196 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1197 Z39.50. But ISO/ILL was, however.
1199 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1200 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1202 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1203 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1205 --- 1.8.5 2002/02/03
1207 New YAZ client features: Command completion and new commands:
1208 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1209 Code provided by Jacob Poulsen.
1211 New call oid_trav, that visits all registered OIDs via callback.
1213 Function ZOOM_record_get now returns const char pointer rather than
1214 void pointer. It saves a lot of type casts.
1216 For YAZ client, command "auth" now allows you to set authentication
1217 in IdPass style. It is enabled when three tokens are given - order
1218 is user, group and password.
1220 Fix memory leaks in MARC record handling for ZOOM.
1222 New option for YAZ client, -k <kilobytes> that sets
1223 maximum record size. Similar to -k option for generic frontend
1224 server and yaz-ztest.
1226 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1228 Prefix query parser reports "fail" when bad attribute set is given.
1230 Fix in MARC decoder. Proximity logging. Fix for attribute set
1231 in scan handler for server. Patches by Shigeru Ishida.
1233 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1236 Configure option --with-openssl=<dir> now works when a directory is
1237 specified. Patch provided by Morten Bøgeskov.
1239 New option for YAZ client, -u <auth>, that sets authentication.
1241 ZOOM fix: error information was sometimes "missing", since error
1242 was cleared/reset too when it shouldn't.
1244 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1246 --- 1.8.4 2002/01/04
1248 Scan for ZOOM API. New object ZOOM_scanset. New functions
1249 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1250 ZOOM_scanset_destroy.
1252 New ZOOM function, ZOOM_connection_last_event, that returns type
1253 of last event (such as "receive data", "send data", "apdu received",
1256 New ZOOM option, schema, that specifies schema for retrieval.
1258 New CCL feature. Qualifiers can be aliases for one or more
1259 other qualifiers (if more than one is given, OR is used).
1261 ZOOM uses named result sets if target supports it.
1263 Two new YAZ client commands: . (dot, which sources a script of YAZ
1264 client commands), and ! (to execute shell command.). Implemented
1267 Working on Debian packages.
1269 --- 1.8.3 2001/11/19
1271 YAZ client enables named result sets only if target supports it.
1273 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1275 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1276 with key="host" to get same result.
1278 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1279 Function Z3950_resultset_record(s) returns references to records
1280 "owned" by resultset. To become owner use Z3950_record_clone.
1282 Function z_ext_record handles Extended Services. Thanks to
1285 --- 1.8.2 2001/11/12
1287 CCL Parser fix: ignore token comma when dealing with and-lists.
1289 Documentation updates for COMSTACK.
1291 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1292 Changed prototype Z3950_records. For some functions, int parameters
1293 were changed to size_t.
1295 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1298 New MARC decode/display function, marc_display_exl, which properly rejects
1299 non-ISO2709 records. YAZ client uses it.
1301 --- 1.8.1 2001/10/29
1303 Fix bug: local attribute set wasn't set correctly in PQF strings.
1307 * Old Z39.50 codecs no longer supported.
1309 Added ZOOM C binding. See http://zoom.z3950.org/
1311 Renamed states for COMSTACKs to avoid confusion with events.
1313 Implemented cs_look and proper cs_rcvconnect.
1315 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1317 Configure detects POSIX threads on OpenBSD.
1319 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1320 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1322 When error is returned from present handler, non-surrogate diagnostic
1323 is returned in present response (and fetch handler is no longer called).
1325 * Minor adjustments to pquery parser (PQF). Token characters may be
1326 escaped by using backslash (C-style).
1328 PQF parser allows string attribute values to be specified. For @attr,
1329 non-numeric characters after the equal-sign are treated as strings
1330 (e.g. @attr 9=title).
1332 CCL trunction character may be defined (@truncation in file)
1334 * function zget_ExtendedServicesRequest sets waitAction to
1335 waitIfPossible (was wait).
1337 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1340 CCL operator names may be set in field definition files (CCL_bibset).
1341 See ccl/bib1 for an example.
1343 Fixes in ASN.1 compiler for C++ compatibility.
1345 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1346 and "op_or" to avoid conflict with C++.
1348 Fixed problem with GNU readline detection on Redhat 7.0.
1350 Added step-size for Scan backend handler.
1352 Fixed bug that made the frontend server crash when no attribute
1353 set was specified for scan.
1355 Front-end server automatically switches to original working directory
1356 when installed as an NT service. Previously -w had to be specified to
1359 Added extended attributes for retrieval module (data1), so that data1
1360 records carry d1_readXML/SGML attributes. d1_read also supports
1361 null-data rules ( <tag/>)
1363 On UNIX when POSIX threads are available, a separate library libyazthread
1364 is created. Programmers should link with that library and the yaz library
1365 when using threads. The reason for the split was that some applications
1366 on Linux, such as Apache, doesn't work well when using shared objects that
1369 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1370 (or any frontend server) in SSL mode by specifying ssl: followed by
1371 address. Only tested on UNIX.
1373 Added feature for CCL module. Virtual structure s=al or s=ol generates
1374 and-list and or-list respectively instead of phrase search.
1378 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1379 log_mask_str. This was done to avoid name conflicts with other libraries
1380 (such as other PHP extensions).
1382 Added raw OID member for preferred record syntax (request_format_raw)
1383 and returned record syntax (output_format_raw) for backend fetch method.
1385 Config file yaz-config now accepts options so that it returns specific
1386 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1388 Shared library support for UNIX using GNU libtool.
1390 * Modified backend interface. Request/Response struct's replaced by
1391 one read/write C struct. For example bend_fetchrequest and
1392 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1393 Every handler - even search has to be registered in bend_init
1394 handler. This means that the YAZ library no longer refers to
1395 external functions and it makes it possible to make the whole
1396 thing a single DLL/SO.
1398 Added Segment handler for backend server.
1400 Added Zmbol/Zebra administrative functions to YAZ client.
1402 Threaded frontend server on UNIX (when POSIX Threads are available).
1403 Starting the server with option -T enables multi-threading.
1407 Added configure option --enable-comp/disable-comp to control use
1408 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1409 located in sub directory asn.
1411 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1412 in ${exec_prefix}/bin along with the other programs yaz-client and
1415 GNU automake used to maintain makefiles.
1417 Added several OID's.
1419 Changed retrieval module so that we can load records with no abstract
1420 syntax defined. Tagpaths in these records are fully composed of string
1423 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1427 On UNIX, the generated makefile now supports a proper 'make install'.
1428 The prefix can be set via GNU configure to set the install location
1429 (default is /usr/local).
1431 * YAZ programs client and ztest were renamed to yaz-client and
1432 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1433 locations, such as /usr/bin,/usr/local/bin,etc.
1435 * YAZ Header files were moved from include to include/yaz. YAZ Header
1436 files are referred to as include <yaz/log.h> rather than <log.h>.
1437 The YAZ include path (-I ..) is therefore the same as before. Programmers
1438 should update their #include statements or use -Ipath/include/yaz
1439 instead. The main motivation for doing this change is that YAZ header files
1440 can be installed in "standard" locations /usr/include,/usr/local/include
1441 without introducing conflicts, since ALL YAZ header files are stored
1442 in subdirectory yaz (under /usr/include for example).
1444 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1445 rather than project/workspace files. We switched because project files
1446 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1449 Changed name of logging function, logf, to yaz_log, to prevent name
1450 clash with some math-log functions. The YAZ header log.h defines logf
1451 to yaz_log (#define) so there should be no incompatibilities by this
1454 Added bend_start/bend_stop handlers for server. These handler are
1455 called on start/stop of server. For windows they are called whenever
1456 a service is started/stopped.
1458 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1459 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1460 in util/yc.tcl. The auto-generated C code structures are, in a few
1461 cases, incompatible with the old decoders. There are differences in the
1462 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1463 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1464 The preprocessor variable ASN_COMPILED is defined when the compiled
1465 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1466 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1467 wish to use the old encoders/decoders you can specify --disable-yc
1470 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1471 version so that it supports both new - and old version of DB Update
1473 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1474 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1475 change. The name parameter can be set to 0 in which no name is specified
1476 for the construction. The macros odr_implicit and odr_explicit sets name
1477 parameter to zero for the construction involved. New macros
1478 odr_implicit_tag and odr_explicit_tag are similar to the others,
1479 except that a name parameter is added. For programmers' that don't use
1480 ODR they probably only need to change the call to z_APDU and z_External.
1482 Added access control facility by interfacing the TCP wrapper library.
1483 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1484 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1485 name of the daemon and enables the access control as specified in
1486 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1488 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1489 den Dool <H.M.vdnDool@kub.nl>.
1491 Added reference ID parameter to most functions in server API - refer
1492 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1494 Changed name of ccl library to libccl.a (was ccl.a).
1496 Fixed bug in decoder for Explain (Category TargetInfo).
1498 Added support for GNU readline in client. Thanks to Jacob Poulsen
1499 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1501 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1502 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1503 IMPLEMENTATION! This change was made to the development version before
1504 the ZIG decided to retract the amendment. If any users MUST be
1505 compatible with the original Update definition, PLEASE CONTACT US, and
1506 we will include a separate definition corresponding to the old Update
1507 ES. Note that because of the change to the ASN.1 of the
1508 TaskPackageRecordStructure we cannot define a single structure that
1509 will support both versions.
1511 * Added const modifier to buffer parameter for some ODR/BER encoding
1512 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1513 completeWAIS, odr_dumpBER.
1515 Fixed bug in client.c which caused a crash when a scanResponse didn't
1516 contain positionOfTerm.
1518 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1519 * will cause an error in a client if a non-YAZ target sends both a
1520 * list of Scan entries and non-surrogate diagnostics.
1522 Retrieval module enhancements. Tag sets may be typed in the reference
1523 to it. From the .abs-file the "tagset" directive takes a third optional
1524 integer type for the tag set referenced. From a .tag-file the "include"
1525 directive takes a third optional type as well. The old "type" directive
1526 in the tag set itself is still recognized but acts as the default type
1529 Backend interface change. Individual Scan terms returned from bend_scan
1530 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1531 in include/backend.h.
1533 Retrieval module enhancements. Multiple tag sets and attribute sets may
1534 be specified in abstract syntax specs. Revised the error/warning for
1535 logging messages reported by the retrieval module when reading the
1538 Object Identifier system (oid_..) changed. The API is backwards
1539 compatible but the oid-routines now allocates new OID's when needed.
1540 Raw OID's may be specified in oid_getvalbyname.
1542 YAZ now uses GNU configure to generate Makefile(s).
1544 * Minor changes in some of the member names of DeleteResultSetRequest and
1545 DeleteResultSetResponse. See include/proto.h.
1547 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1548 and added member 'languages' in TargetInfo (which was missing).
1550 Changed the way attribute sets are handled in the retrieval
1551 module. These are now cached, just like the abstract syntaxes
1554 Changed YAZ so that it links with compiled ASN.1.
1556 Added Explain-schema definitions and mapping routines. The following
1557 Explain categories have been implemented: AttributeDetails,
1558 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1560 Fixed minor bug in Windows version of Server Library.
1562 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1564 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1566 Added EXTERNAL: UNIverse Resource Report (non-standard).
1568 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1569 ENUMERATED and SET OF.
1571 * Added 'const' to some of the char pointer arguments for the
1572 functions, data1_read_node, data1_getelementbytagname,
1573 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1576 Fixed bug in data1_insert_taggeddata - the last_child member of
1577 parent wasn't initialised.
1579 * Changed data1_read_record and data1_read_node so that the supplied
1580 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1581 doesn't refer to any parts of the "SGML"-buffer.
1583 Fixed bug in server library (Windows version of statserv_remove).
1585 * Changed code so that it compiles as C++. The type definition
1586 of Odr_fun which is a member of Odr_arm was changed. The result is,
1587 that an explicit typecast is needed for the fun pointer when
1588 using Odr_arm - as in:
1589 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1591 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1593 Implemented the new structured date and time definition as approved
1594 by the ZIG. Added schemaId element to the specificTag in Espec-1
1595 (also approved at the last ZIG). Thanks to RVDM.
1597 Added some Object identifiers (RVDM).
1599 Changed the Update Extended Service (RVDM).
1601 Added command "refid" to client which specifies referenceId for
1602 the following requests.
1604 Implemented extended service handling for server. See ztest.c
1605 for an example as well as backend.h. New handlers are registerd
1606 in the Init handler.
1608 * Changed interface for sort in server.
1610 Added new members to statserv_options_block. It allows a server
1611 to read options from another source than just the command line. Thanks
1612 to Charles Woodfield.
1614 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1615 renamed to zboolean. Some C++ compilers complained about the name.
1617 Minor changes to gils.abs. Added index 's' (sort) on title
1618 and date/time-last-modified.
1620 --- 1.4pl2 1998/1/30
1622 Fixed bug in server library regarding inetd mode (-i). This bug
1623 was introduced by release 1.4.
1625 --- 1.4pl1 1998/1/29
1627 Added sort facility in client and backend server interface.
1629 Fixed problem with dependencies in Makefile(s).
1631 Fixed bugs for encoders/decoders of extended services and
1634 Implemented sub-tree feature for schemas. Sub-trees are
1635 referenced in *.abs-files. See explain.abs for an example
1636 of the use of this feature.
1638 Modified bib1.att; local attributes for ANY didn't include
1639 ANY itself (only affects use of the retrieval module).
1641 Fixed bug in plain SGML reader in function data1_read_node:
1642 tags with prefix "var" was incorrectly interpreted as variants.
1644 Added feature "sub-schemas" to enable references to - and definitions
1645 of - group of elements.
1647 * Removed member parent from type data1_element (in data1.h).
1649 Implemented function odr_nullval() that returns the value of
1652 * Removed member num_children from data1_node (in data1.h).
1654 Made NT service interface part of the server library. The
1655 function statserv_main uses the NT service when required and
1656 calls the statserv_start / statserv_close routines.
1658 Routine zget_SearchRequest and zget_PresentRequest fills
1659 resultSetName/Id member with "default" instead of "Default".
1661 Fixed memory leak in server. Request queue member wasn't freed.
1663 Fixed nmem_exit so that memory is freed.
1667 Revised the CCL parser utility to be thread safe.
1669 Added function, oid_ent_to_oid, to replace the function
1670 oid_getoidbyent, which is not thread safe.
1672 * Added nmem_init and nmem_exit to initialize and release
1673 NMEM resources. Function nmem_init should be called once in the
1674 initial thread before NMEM/ODR is used. statserv.c and client.c
1675 have been changed accordingly. The change was necessary to make
1676 NMEM thread safe. The NMEM memory pool is shared amongst threads
1677 in a process. Unix-based applications will still work fine without
1680 Added NT Services interface for the the Z39.50 (statserv) Server.
1681 Refer to the ztest.c source on the usage.
1683 Windows 95/NT port using MSVC5.0. Project files are included in the
1686 * Defined new 'global' handle for the retrieval (data1) system. The
1687 new handled, data1_handle, describes the state of the data1 system.
1688 This handle is passed as first argument to virtually all
1689 data1 related routines. The functions data1_create and data1_destroy
1690 creates and destroys a data1 handle respectively.
1692 Added ODR encode stream member to all backend request structures
1693 init, search, scan etc. This stream should be used to allocate all
1694 memory used for the response when thread safe operation is needed.
1696 Changed the comstack utility, cs_addstr, to be thread safe. The
1697 returned hostname string returned by the function is now part the
1700 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1701 function. The cs_straddr takes a COMSTACK handle as argument, so this
1702 function must be used after cs_create and before bind/connect.
1703 This function is thread safe.
1705 Moved test server to 'ztest' directory - generic server code still
1706 in 'server' directory.
1708 Made prefix query (pquery.c) utility thread safe.
1710 Added new function modifier YAZ_EXPORT to 'export' public DLL
1711 functions when using windows (see include/yconfig.h).
1713 Added definitions to the OID database (util/oid.c) (RVDM).
1715 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1717 Added call to ccl_rpn_delete in client program.
1719 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1720 release of RPN structure.
1722 Added support for C++, headers uses extern "C" for public definitions.
1723 With input from RVDM.
1725 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1726 Thanks to Ronald van der Meer (RVDM).
1728 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1730 Added support for private extensions to the OID database
1731 (oid_setprivateoids()). Thanks to RVDM.
1733 Added optional, physical ANY (key replication)
1735 Fixed null-reference problem in GRS-1 output filter.
1737 Proximity operator added to Prefix Query Format (PQF).
1739 In test client command "base" accepts multiple databases.
1741 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1745 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1747 Smallish bug-fixes in the new encoders/decoders (explain).
1749 Bug fixed in DeleteRequest.
1751 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1753 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1755 Added SOIF syntax (using private OID for now) to retrieval module and client.
1757 Added Update extended service.
1759 Added SearchResult-1 additional info structure.
1761 Added optional CCL (ISO8777) interpreter as separate module. Available
1764 --- 1.2 1996/6/10 (1st anniversary release)
1766 Added Summary record syntax. Lightly tested.
1768 Added OPAC record syntax. Untested.
1770 Added ResourceReport service encoders/decoders. Untested.
1772 Fixed bug in z_Unit - wrong tagging on unitSystem.
1774 Fixed bug in the DiagRecs decoder.
1776 Added options for max PDU size and session timeout to frontend-server.
1778 Added documentation of query-language parsers and other supporting utilities.
1780 [frontend-server] Added Attribute set to the bend_scanrequest API.
1782 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1783 surrogate diagnostics were generated.
1785 [retrieval] Allow multiple local values for attribute.
1787 [retrieval] Allow multiple attributes per element in .abs files. index type.
1789 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1791 --- 1.1pl2 1996/4/10
1793 Minor changes, mostly specific to Zebra's requirements (retrieval)
1797 Repaired bug in frontend server when running multiple listening
1798 endpoints in dynamic mode.
1800 z_External() now won't break if a known, ASN.1 value comes encapsulated
1801 in an octet-string. The value will pass through unmodified in an Odr_oct.
1803 Added a bit of code to the demo client to decode & display
1804 ASN.1-structured records represented in the octet-aligned branch of
1805 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1807 Added z_ext_getentbyref() to the ASN module. Doc updated.
1809 * Completed the SCAN definition in the ASN module. This may break SCAN
1810 code based on older YAZ-versions at compile-time. The fix is easy -
1813 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1814 under the SCAN definition. Remember to initialize this, server-people.
1816 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1817 that this does not extend to ODR and ASN.
1819 Comstack allows insertion of established socket (primarily for
1820 inetd-operation of servers). Doc updated.
1822 Front-end server can now start from the inetd in TCP mode. Doc
1825 --- 1.0pl4 1996/1/24
1829 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1830 the rank and record number.
1832 Adjustments to the frontend server.
1834 Fixed diagnostic BER dumper. It ignored the file argument.
1838 Various changes to retrieval module.
1840 Changed the union discriminators of the protocol files from enums to
1841 ints paired with #defines.
1843 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1846 *Changed operator in the RPN structure to 'roperator', again to avoid a
1849 Fixed problems in Explain decoders/encoders.
1851 --- 1.0pl2 1995/12/6
1853 Memory bug in log module fixed.
1855 --- 1.0pl1 1995/12/5
1857 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1859 Bug in Explain DatabaseInfo module fixed.
1861 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1865 The shift to v1.0 signals that we now consider the *core* functionality
1866 of YAZ reasonably stable (the core being more or less equivalent to
1867 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1868 tested (Explain not at all - though that will happen soonish).
1870 Minor changes to code to support Windows port.
1872 Various minor changes after we're getting to use GRS-1 & co. more.
1874 Added Espec-1 format.
1876 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1877 of the protocol and it cannot be selected when encoding (maps into 'string'
1878 when decoding). Needed to talk to some servers.
1880 Demo client can request simple element set names.
1882 Added Diagnostic Format encoders/decoders.
1884 Added simple Close handling to frontend server (no hooks for resource
1885 reporting yet), and demonstration client.
1887 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1889 --- 1.0b3 1995/08/24
1891 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1892 handled incorrectly when records were requested in the searchResponse. This
1893 will only affect you if you use the frontend-server.
1895 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1896 Test-client will ask for and print GRS1. Ztest will return dummy records
1899 Added Explain encoders/decoders to the service-level API. Untested.
1901 Added Extended Services: Item Order encoders and decoders to the Service-
1902 level API. Untested. We could use a recent copy of the pertinent bits
1903 of the ILL protocol to add those bits.
1905 Added diagnostic format 1 encoders/decoders to the service-level API.
1908 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1909 odr_cons.c, which causes a more correct output.
1911 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1912 was always set to 0 when no records were requested in the searchRequest.
1914 * Added better external-handling. This shouldn't harm old code that
1915 *encodes* externals. It can break code that looks for a
1916 'single-ASN1-type' representation, since those types that are known
1917 are now decoded immediately. Look at the SUTRS sample code in
1918 seshigh.c and client.c. Documentation updated.
1920 Handling of structured records in bend_fetchresponse. Length -1 marks
1921 structured record, type is deduced from format field.
1923 --- 1.0b2 1995/06/27
1924 Fairly quick maintenance release to add SUTRS support.
1926 Fixed handling of SUTRS records in the demonstration client.
1928 * Added format field to the bend_fetchrequest and bend_fetchresponce
1929 structures of the backend API (frontend server). When the record is
1930 returned, the value of the format field is mapped to an OID. The
1931 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1932 of the record. The special value VAL_NONE in the bend_request means
1933 that no specific format was requested by the client. Documentation
1934 updated accordingly. Test server (ztest) will return a fixed dummy
1935 SUTRS record if your client requests SUTRS.
1937 Documentation updated accordingly.
1939 You can now set external libraries and RANLIB support in the top-level
1943 First public release.
