1 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2 SL_CTX_use_certificate_file. See
3 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
4 for more info. Thanks to Ko van der Sloot.
8 Bug #600: SRU GET, POST support for yaz-client. Introduced
9 command 'sru' which selects method SOAP/GET/POST.
11 Allow missingValueAction to be specified for the sortspec string -
12 function yaz_sort_spec. By default, the missing value action is null.
13 Use ! to specify "abort". Use = followed by stringvalue to specify default
16 Ensured that Present-handler (if defined) is called in GFS before any call to
17 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
18 searchRetrieve requests.
20 Documentation for YAZ is now based on the Docbook XML/XSLT using
21 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
22 is no longer depending on jade/openjade or docbook-to-man scripts.
23 PDF is no longer part of the distribution - but can optionally be
24 made using DSSSL/jadetex or FOP.
26 Added retrieval handling support in Generic Frontend Server to support
27 conversion between MARC/XML as well as XSLTtransforms. See
28 etc/yazgfs.xml for an example.
30 Added Authentication support to Generic Frontend Server in SRU
31 mode. Authentication using HTTP Basic is supported, as is the use
32 of 'x-username' and 'x-password' parameters in the request itself.
34 Added support for a new character set MARC8s identical to MARC8 except
35 that it converts combined characters to single Unicode characters in the
36 Latin-1 range (when possible).
40 ASN.1 compiler 0.4: generates brief Doxygen file header for
41 generated .h/.c files.
43 Utility yaz_iconv now supports conversion to MARC-8.
45 New facilities for the MARC module. The reading - and writing of
46 content are separate methods for the yaz_marc_t handle. The following
47 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
48 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
49 format). Write functions have prefix yaz_marc_write_.. The existing
50 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
51 available. Removed support for OAI-MARC and simplexml (not the
54 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
55 to be returned for this connection.
59 Allow multiple languages and charsets to be specified with
60 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
61 negcharset iso-8859-1,utf-8
63 Translation of proximity nodes from CQL into PQF now works.
65 Moved to automake 1.8, 1.9.
67 Added function yaz_log_set_handler which allows a log handler to be
68 installed. This handler will be called for all log messages. Output
69 to file is also produced; but that can be disabled by passing NULL
70 fname to yaz_log_init_file.
72 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
74 For SRW (including GFS), accept application/soap+xml as content-type
77 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
78 produces NO stylesheet reference even if a default stylesheet is specified
83 Updated Windows package to include yazd.dll + yazd.lib for the
84 Development component.
86 If the environment variable YAZ_LOG is set, then it is used as a
87 string indicating the default level of logging to use if not
88 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
89 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
90 used as before. So, for example, to omit warnings from YAZ logging,
93 cql_transform() now map structure and other attributes before indexes,
94 so that index-specific structures and other attributes can override
95 defaults. So now a combination of mapping specifications such as:
97 index.dc.date = 1=date-modified 4=5
100 cql_transform() now also respects the "always" mapping specification,
101 which establishes an initial set of attributes to be used for all
102 terms except where overridden by more specific attributes associated
103 with the index, relation or modifier.
105 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
106 which mode to use; one of "post", "get" or "soap" (SRW, default).
108 Fixes for yaz_iconv routines: changed trie-based character set conversions
109 to use only non-negative values for bit fields due to Sun's C compiler not
110 supporting negative values.
112 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
113 sequences where not read correctly. Fix by Rustam Usmanov.
115 Updated win/makefile to use options, settings which makes things
116 compile with VS C 2005.
118 --- 2.1.12 2006/02/01
120 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
122 In ZOOM socket code, use select instead of poll on MacOSX.
124 ZOOM-C now support client-side compilation of CQL into RPN that is
125 sent to the server, enabling CQL to be used against all Z39.50
126 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
127 ZOOM_query object, and submit it using ZOOM_connection_search().
128 The CQL-to-RPN translation uses a configuration file, the name of
129 which must be specified in the Connection's "cqlfile" option.
131 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
132 function, which takes as its start-term parameter a ZOOM_query object
133 (which may have had either CQL or RPN set into it).
136 --- 2.1.10 2005/11/29
138 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
139 GFS to support this as well. Backend handler, bend_srw_update, does the
140 update work. Code contributed by Ko van der Sloot.
142 Allow retrieval of Search Result-1 information in ZOOM by the use of
143 options that are attached to a result set. ZOOM documentation updated
146 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
147 UTF-8 conversion. Patch by Raj Patel.
149 Added option -m to GFS to control formatting of timestamps in log file.
151 Added 'exit' as synonym for 'quit' in yaz-client
153 Added support for specifying SRW resultSetId + resultSetIdleTime in a
154 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
155 for the new members. Patch by Ko van der Sloot.
157 Added support for SRU POST. It is supported for content-type
158 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
160 Do not build the separate Multi-threaded (MT) library libyazthread.la.
161 Instead make the library libyaz.la multi-threaded. Threading as a whole
162 can still be disabled by configure option --disable-threads. Previosly,
163 with older GLIBCs there were problems with MT libs under Apache. This
164 has now been fixed a long time ago.
166 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
169 CQL module modified to be case insensitive for relations/indexes/operations.
171 Fixed bug in CQL transform code: incorrect value relationModifieder
174 Added 'show all' command for yaz-client which retrieves all results
177 Added new yaz-client, xmles, which takes a (private) OID and
178 a document to be sent as an extended service request.
180 Describe new yaz-client commands wait_response and set_auto_wait.
182 Increase TCP/IP listener backlog from 3 (which I am guessing was
183 copied from the SunOS manual entry way back when) so SOMAXCONN, so
184 that the socket will queue as many incoming connections as it's able
185 to handle ongoing connections. In other words, it will never now
186 refuse a connection that it would be able to handle merely because
187 it's not got around to accepting() enough of the pending connections
188 yet. This is the behaviour anyway under Linux, where the listen()
189 argument is ignored; but not under BSD and on systems such as
190 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
191 YAZ-based servers should now be uniform across operating systems in
194 yaz-marcdump uses 64-bit file access on some systems. This is enabled
195 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
196 This allows yaz-marcdump to read large MARC batches (>2 GB).
198 Modified all YAZ source files - except the source which is auto-generated
199 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
202 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
203 corresponding to the existing *_setl() function. These allow option
204 values containing arbitrary valuues.
206 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
207 ZOOM_resultset_sort() in new applications. Its behaviour is identical
208 except that it returns an indicator of whether or not the sort
209 criterion was accepted (0 for OK, -1 for invalid).
213 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
214 MARC output rather than returning "new" buffer.
216 yaz-client warns about unknown init options.
218 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
222 Added support for SRW sort in Generic Frontend Server. Patch
223 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
224 sortKeys - or NULL if none is provided.
226 Fixed bug #307: It was impossible to specify indefinite/no timeout
227 for ZOOM_event. Special timeout value -1 now means indefinite timeout
230 Added support for multiple languages and charsets to be specified in
231 ZOOM. Each charset/language is separated by a blank. If negotiation is
232 in effect in init-response, Option
233 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
234 Code based on patch by Vasiliy Osadchuk.
236 Fixed bug #306: infinite recursion that occurred when calling
237 yaz_log_level_init as the first call (before other log level or
240 Fixed bug in scan handling in front end server: if preferred-Position-In-
241 Response was non-present, a NULL pointer referece was performed.
245 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
246 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
247 now defined for all those error codes. So instead of putting 109 in
248 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
249 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
251 Modified the yaz-marcdump utility to skip garbage bytes between MARC
254 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
256 Program yaz-client now exits and produces an error message if multiple
257 Z39.50 servers are specified on the command line (none or one allowed
260 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
265 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
267 Fixed bug #272: Preserve spacing for CCL terms.
271 Added support for virtual hosts and multiple backend servers for
272 the YAZ frontend server. The configution is XML based and
273 support specificition of CQL to RPN mappings and explain information.
274 See section "Virtual Hosts" in the YAZ manual.
276 Extended OPAC display utility. OPAC display utility renders
277 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
278 to supplement yaz_marc_decode_wrbuf.
280 Fixed a bug in MARC decoder that could caused it to crash for some
281 invalid MARC records. More diagnostics and warnings where added in
282 XML output (warnings, etc are stored in comments).
284 --- 2.0.34 2005/02/08
286 Fixes for UNIX domain sockets. Bug #261.
288 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
290 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
291 Added yaz_marc_subfield_str which defines subfield lead string which is
292 used in YAZ_MARC_LINE format. Default string is blank+$. Added
293 yaz_marc_endline_str which defines end of fields string used in
294 YAZ_MARC_LINE format. Default string is newline.
296 Experimental support for MarcXChange. This format can be produced
297 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
298 http://www.bs.dk/standards/MarcXchange.xsd
300 Added yaz-client commands scansize that sets maximum number of
301 entries to be returned by scan.
303 --- 2.0.32 2005/01/11
305 Added support for SRW scan in yaz-client and Generic Frontend Server.
307 * Added whereInList member to SRW Scan Term.
309 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
311 Fixed NMEM system to return aligned blocks on the smallest boundaries
312 that are suitably aligned for all possible types on the particular
313 architecture YAZ is being built for.
315 --- 2.0.30 2005/01/04
317 Fixed numerious warnings that was issued with newer versions of GCC.
319 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
320 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
323 Make YAZ Generic Frontend Server slightly faster.
325 Enhance (and reduce) logging for Generic Frontend Server.
327 Revert YAZ log system so that it flushes every write operation
328 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
330 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
331 instead of LOG_, due to name clash with syslog(3). LOG_ are still
332 present. New applications should define YAZ_USE_NEW_LOG=1 - this
333 will effectively disable old definitions.
335 --- 2.0.28 2004/11/09
337 Added yaz_log_time_format which specifies log format using
340 Added yaz_log_module_level which returns mask for a module. Value
341 is non-zero mask a if module is enabled; zero if disabled.
343 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
344 in include/yaz/cql.h.
346 Fixed bug #176: Dont throw diagnostics on empty SRU args.
348 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
350 Fixed bug #172: RPM builds does not enable SSL.
352 Doxyfile.in part of dist. Doxyfile generated by configure.
354 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
355 are given and the corresponding component does not exist.
357 Extend CCL documentation in YAZ reference. Describe r=r.
359 --- 2.0.26 2004/10/01
361 Fixed MARC->MARCXML conversion to properly deal with
362 fields, subfields, indicators having non-ASCII characters.
364 Fixed MARC->MARCXML conversion so that ASCII control characters
365 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
368 Added YAZ GFS support for conversion from Z39.50 surrogate
369 diagnostics to SRW surrogate diagnostics.
371 Bug fix: YAZ GFS did not return schema in explainResponse.
373 --- 2.0.25 2004/09/30
375 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
376 now converts recordSchema to elementSetName as well as schema URI.
378 Fixed bug in COMSTACK that prevented HTTP request packages from being
381 --- 2.0.24 2004/09/29
383 Added CCL facility r=r "range" which is similar to r=o "ordered" but
384 does not require white-space before and after the dash in a range, e.g.
385 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
388 Fixed a few AC_TRY_LINK configure tests that did not operate properly
389 due to new GCC removing "redundant" code.
391 Added yaz-client commands scanpos and scanstep that sets preferred
392 position and step-size for scan.
394 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
396 Added CCL utility ccl_qual_buf which parses one or more CCL
397 spec lines in a buffer.
399 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
400 of name and value - ignoring empty lines and comments.
402 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
404 Added odr_get_element_path which returns current element path for an
405 ODR handle. This utility is useful in error handling or user-defined
408 Added ODR_PRINT utility odr_set_stream which is is a more generic
409 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
410 to a write function and pointer to close function. The close function - if
411 non-NULL - will be called during odr_destroy.
413 Fixed bug in CCL parser where truncation char was not removed from
414 right side when truncation=both was in effect.
416 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
419 --- 2.0.23 2004/08/11
421 Fix buffer overrun in CQL parser when dealing with proximity (%).
423 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
424 to UTF-8/UCS conversion is now only based on codetables.xml.
426 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
428 --- 2.0.22 2004/08/06
430 Add support for more "commit changes" in ZOOM (uses Extended Services).
432 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
435 Yet another small fix for configure of SSL.
437 --- 2.0.21 2004/05/14
439 Fix SSL libs for configure when --with-openssl=DIR is given.
441 --- 2.0.20 2004/05/10
443 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
445 SSL comstack now uses yaz.pem certificate file on server side
446 by default. Certificate filename can be configured by calling
447 comstack function cs_set_ssl_certificate_file before cs_bind is used.
449 Fix bug regarding multiple calls to ZOOM_connection_connect.
451 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
453 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
454 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
456 ZOOM now allows inspection of X509 peer certificate for verification.
457 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
459 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
460 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
461 as "modular" but it simplifies things.
463 Added cs_get_peer_certificate to that returns peer X509 PEM.
465 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
466 NULL if SSL is unavailable.
468 Documentation about MARC decoding tools.
470 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
472 --- 2.0.19 2004/03/30
474 Rename CHANGELOG to NEWS to follow GNU style packing.
476 Fix bug with missing initialization of member in init_diagnostics.
477 This bug affects threaded version of GFS server.
479 --- 2.0.18 2004/03/20
481 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
484 Ensure zlib.dll is packed with Windows install.
486 --- 2.0.17 2004/03/17
488 Fix encoding of xsd:string to use text instead of CDATA.
490 Fix endless loop in CQL parser with unbalanced ".
492 Use a more compact way to store MARC-8 conversion tables.
494 --- 2.0.16 2004/03/16 Debian only
496 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
499 Update CQL parser to use new CQL 1.1 modifiers for booleans and
504 --- 2.0.15 2004/03/01
506 Another fix for decoding of XML packed records.
508 --- 2.0.14 2004/02/25
510 Fixes for Chunked encoding. White space not ignored after length spec.
512 Update NS and use default NS for SRW diagnostic elements.
514 --- 2.0.13 2004/02/23
516 Implement ZOOM_resultset_cache_reset which resets record cache.
518 Implement ZOOM_resultset_sort which sorts a result set.
520 Implement chunked HTTP transfer.
522 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
524 --- 2.0.12 2004/02/16
526 Added member 'schema' to bend_explain_rr structure so that backend
527 can specify explain record identifier. Defaults to Zeerex 2.0.
529 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
531 --- 2.0.11 2004/02/16
533 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
536 Added init command for yaz-client which sends "extra" init request.
538 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
539 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
541 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
543 Make ZOOM error code for "invalid query".
545 Fixed compilation for SSL which wasn't properly enabled for all platforms.
547 --- 2.0.10 2004/02/05
549 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
552 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
554 Added option -p <file> to make Generic Frontend Server to write PID file.
556 Added option -D to put Generic Frontend Server in background on its own.
558 Make ZOOM C recognize option "password". If unset, "pass" is used
559 (for backwards compatibility).
561 Fixed a bug in Generic Frontend Server that could make it crash if a
562 client sets characterSetNegotation bit, but didn't pass negotiation stuff
565 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
566 Must be issued before open, in order to be in effect.
568 --- 2.0.9-6 2004/01/12 Debian/Windows
570 Make the SRU server more picky WRT unknown params, etc.
572 Bug fix: ZOOM scan response didn't return displayTerm - when present.
574 New YAZ client command, options, that sets Z39.50 options.
576 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
577 options from a string of tokens (one token for each option bit).
579 Update SRW diagnostic code messages.
581 --- 2.0.9-5 2004/01/07 Debian/Windows
583 Handle user defined stylesheet for SRW/SRU.
585 --- 2.0.9-4 2004/01/06 Debian/Windows
587 Fix bug in decoding of Content-Length.
589 --- 2.0.9-3 2004/01/06 Debian/Windows
591 Fix a bug with decoding of XML packed records.
593 --- 2.0.9-2 2004/01/05 Debian only
595 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
597 Fix bug in SRW/SRU diagnostics decoding.
601 Fixed bug in Generic Frontend Server which could drop records exceeding
602 preferred message size. Reported and fixed by Irina Dijour.
604 Fixed calculation of package size for structured records in Generic
605 Frontend Server. Reported and fixed by Irina Dijour.
607 Fixed namespace for SRW/SRU diagnostics.
609 Fixed SEGV in yaz-client that occured for HTTP connection errors.
613 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
614 this version is incompatible with version 1.0 and older YAZ SRW/SRU
617 CQL changes to reflect recent changes to the specification:
618 * Documentation talks about context sets instead of index sets.
619 * Documentation talks about indexes instead of qualifiers.
620 * The CQL-to-PQF transformer's configuration file now uses
621 "index.set.name = <attributes>" instead of the old form
622 "qualifier.set.name = <attributes>". (Both forms are still
623 understood but the latter is deprecated.)
624 * CQL terms with no explicit index specified are now interpreted as
625 cql.serverChoice instead of srw.serverChoice (which of course
626 behaves exactly the same.)
630 MARC conversion can now generate ISO2709 output in another
631 character set. yaz-marcdump uses this facility if you invoke it
634 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
635 functions from there can be used from C++.
639 Frontend server now transfers memory from decoded packages to stream
642 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
643 references to show up.
645 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
646 the ZOOM Abstract API. The older names for the same options are still
647 also supported for the benefit of old applications.
649 ZOOM-C supports "implementationId" and "implementationVersion" options
650 to go along with "implementationName". These allow the user code to
651 specify identification strings to be sent to servers.
652 Add OID for the new ExtLite attribute set.
654 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
655 as requested/supplid by Ere Maijala <ere@atp.fi>
657 For generic frontend server, reverse the order of
658 "toolkit-supplied / application-supplied" strings sent as implementationId,
659 Name and Version. Also, remove the spaces around the slash. This brings
660 the GFS in line with the behaviour of ZOOM-C on the client side.
662 Add function ZOOM_scanset_display_term.
664 yaz-client shows scan displayTerm if present.
666 Utility yaz-iconv is now installed by default along with the man page
669 Extend configure check for OpenSSL to use pkg-config where available (such
672 Incorporate patch by Morten Bogeskov which allows a Unix file socket
673 server to specify uid/gid/mask for socket using the format
674 unix:[user=uid,][group=gid,][umask=mask,]file=path
675 If file= is omitted the existing format is assumed, e.g.
677 in which case the mask is 0666 (rw for everybody).
679 Major restructure of YAZ source. All source in libyaz is in src directory.
680 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
681 util (utility programs such as ASN.1 compiler, yaz-marcdump).
683 Added man page for utility yaz-marcdump (used to be called marcdump).
684 yaz-marcdump is installed by 'make install'.
686 Fixed a memory leak in Generic Frontend Server that occurred when decoding
687 of incoming package failed.
689 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
691 Change prototype of odr_perror: add const to message string.
693 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
695 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
696 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
697 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
698 DNS lookup. There should not be any compatibility problems with this
699 assuming that blocking=1 or 0 is used.
701 Fix bad reference in UNIX comstack in function cs_addrstr.
703 Fix for compilation on AIX.
705 The generic front-end server (server/seshigh.c) now supports returning
706 Init diagnostics to the client in User-information-field, in
707 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
712 Allow any CQL relation (not just all,any,exact,scr).
714 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
715 that features the same UI.
717 Implemented command update0 in YAZ client which is equivalent to
718 update but uses old of Ext Update ASN.1.
720 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
721 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
722 Previously no OID was used for this info.
724 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
725 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
726 returns 'malformed search term' otherwise.
728 SortResponse member resultCount now set to NULL in sort handler of
731 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
734 Add three new utility functions for translating OIDs between various
735 formats -- symbolic name such as "Usmarc", minus-1-terminated int
736 arrays and dotted strings such as "1.2.840.10003.9.5.1":
737 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
738 char *oid_to_dotstring(const int *oid, char *oidbuf);
739 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
741 Reverted modifications for ES Update definition for z_IU0Update
742 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
743 is back to YAZ 2.0.2.
745 String value attributes for CCL parser.
747 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
748 which their FirstSearch server returns in Init responses, sometimes
749 carrying useful diagnostic information when Init fails. This has the
750 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
751 "z39.50/oclcui.asn", where its definition is somewhat different from
752 what OCLC document on their web-site, as required to interoperate with
755 Support for anonymous authentication in yaz-client. Use the command
758 * Fix the OID of the Index Data-local "admin" Extended Service from
759 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
760 the 1000, which indicates a locally-defined OID, was a mistake.
764 Fix CCL directive @case handling so that it affects string match for
765 both CCL keywords and qualifiers.
767 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
768 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
769 Decoder has been updated with ASN.1 changes as listed in
770 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
771 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
772 z_IUUpdate, remains unchanged.
774 ZOOM_record_get may now return a record in a specific character set.
775 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
776 "from" is the character set of record as returned by target. "to" is
777 the character set to be returned. If omitted, "to" is UTF-8.
779 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
781 New ODR utility, odr_getelement, which returns name of element for
782 which encoding/decoding failed.
784 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
785 in cases where a required element was omitted.
787 Bug fix: some MARC8 sequences were not converted.
789 New ZOOM option "step" which specifies number of records to be
790 retrieved in one chunk. Used in conjunction with "start" and "count".
792 SRW support for yaz-client. Use scheme http: to use it, e.g.
795 yaz-client no longer does (un)intelligent character set conversions
796 by default. Can be enabled with charset and marc_charset commands.
798 xmalloc trace fix for 64-bit systems such as DEC alpha.
800 Solaris 2.6 compile fix.
802 New function, cql_strerror() translates SRW error codes, as returned
803 by cql_transform_error(), into human-readable English strings. Used
804 in yaz-client diagnostics when appropriate.
806 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
807 converts it into a type-1 query which is sent to the server. This
808 makes CQL available for use with all Z-servers, as opposed to the tiny
809 minority that can handle CQL queries themselves.
813 New Debian package layout similar to the Redhat Package layout.
815 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
816 and search result respectively.
820 Redhat package is now several packages: libyaz (runtime libraries),
821 libyaz-devel (development and documentation, and yaz (utility programs).
822 Package spec file by Morten Bøgeskov.
824 New member 'schema' in struct bend_fetch_rr which the name of requested
825 schema (SRW/SRU) for record (or NULL if none was given). The fetch
826 handler MAY set this to reflect the schema of the returned record.
828 New member 'display_term' in struct scan_entry. GFS now sets member entries
829 and allocates scan entries to be filled by user scan handler. In previous
830 version, entries member was allocated by the scan handler. That still works,
831 but the GFS will ignore member display_term - assuming it was NOT set by
832 the handler. The fact that the GFS now allocates the entries both allows
833 for new members and makes a scan handler easier to write.
835 Fix CQL lex buffer overflow.
837 SRW/SRU recordPacking. For SRW default recordPacking is string. For
838 SRU default recordPacking is string.
840 SRU protocol support for frontend server.
842 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
844 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
846 Added scan for the ZOOM shell (zoomsh).
850 * String Identifers for Schemas (Amendment 5).
851 http://lcweb.loc.gov/z3950/agency/amend/am5.html
852 Old definition for schema
853 Odr_oid *schema; /* OPT */
858 Z_InternationalString *uri;
859 #define Z_Schema_oid 1
860 #define Z_Schema_uri 2
863 * resultCount parameter to Sort Response (Amendment 1).
864 http://lcweb.loc.gov/z3950/agency/amend/am1.html
866 Support for SRW 1.0 over HTTP. This is an optional feature and
867 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
870 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
871 on the same port. SRW SearchRetrieveRequests are mapped
872 to bend_init,bend_search,bend_fetch,bend_close.
874 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
876 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
877 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
879 ZOOM connections are SRW based if schem http is used for hostname
880 in connect, e.g. z = ZOOM_connection_new("http://myserver");
881 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
883 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
884 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
885 distance=n, order=true/false, relation=le, prox unit=word. If
886 n is omitted, distance 1 is used.
888 Fixed problem with C compiler include path in wrong order.
890 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
891 on Solaris. Patch from Ko van der Sloot.
893 New MARC decode API. All new functions operate on a yaz_marc_t
894 handle. The most important new functions are: yaz_marc_create,
895 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
896 decode and destroy respectively. Decoder can produce formats
897 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
898 include/yaz/marcdisp.h.
900 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
901 to UTF-8, UCS-32, wchar_t or Latin-1.
903 * Prototypes for yaz_iconv_-functions moved to separate header
904 include/yaz/yaz-iconv.h.
906 Make a few private functions 'static' in unix.c. This prevents
907 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
909 For ZOOM connection, the options targetImplementation{Id,Name,Version}
910 are set when Init Response is received.
912 New function ZOOM_connection_error_x similar to ZOOM_connection_error
913 but returns diagnostic set as well.
915 New function yaz_strerror which is a portable wrapper for
916 strerror/strerror_r/GetLastMessage.
918 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
919 is returned for MARC. If type is "oai", then OAI MARC is returned.
921 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
926 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
928 Fix bad race conditions on SIGTERM and terminate gracefully in
931 Move retrieval (data1) module to Zebra since nobody seems to be
934 Add GRS-1 render for ZOOM using same format as yaz-client.
938 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
940 Fix broken ESpec handling in data1 module.
942 SGML reader parses comments and makes them part of the data1 tree.
944 Added several type casts so that YAZ compiles as C++ code.
946 ZOOM didn't handle PDU encoding failures properly.
948 Added more Bib-1 diagnostics (approved extensions).
950 GNU configure: better check for iconv.
952 More portable use of accept, getpeername. Check for socklen_t. Use
953 int/size_t if socklen_t is not defined.
957 PQF parser rejects bad queries - including those with extra
958 characters in them. PQF parser used to silently ignore that.
959 Cleaner API for PQF added, which allows you to get detailed
960 error information for bad queries (see yaz/pquery.h).
962 Fixed bug in ZOOM_record_get for type "database".
964 Implemented mini iconv library supporting conversions between
965 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
967 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
971 Fixed ZOOM C record cache so that preferredRecordSyntax and
972 elementSetName is used to check for already fetched records.
976 Added three members in bend_initrequest structure to facilitate
977 character set negotiation.
979 Fixed a bug in frontend server that could cause indefinite
980 loops under rare conditions.
982 Revised character set utilities (charneg.h) so that encoding
983 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
985 For PQF, directive @term <type> sets term type for Scan/Search.
986 Here <type> is general, string, numeric, null. The term type
987 is inherited - just like @attr.
989 New call odr_set_charset that sets character set conversion for
990 international-strings on a ODR stream. Prototype is:
991 int odr_set_charset(ODR o, const char *to, const char *from);
992 The InternationalString is still represented as C string in YAZ
993 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
994 won't). On the protocol level, you can use any encoding.
996 Support for UNIX sockets in ZOOM.
998 Solaris recv sometimes returns errno == ENOENT. It is treated as
999 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1001 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1002 both client and server. Code by Morten Bøgeskov.
1004 --- 1.8.7 2002/05/22
1006 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1007 that they can be used directly from Visual Basic. You must recompile
1008 your windows APP if you're using ZOOM.
1010 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1011 Commands "lang" and "charset" sets language and character set respectively.
1012 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1013 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1015 Attributes from multiple CCL fields may be OR'ed rather than merged
1016 using directive "@field or". Fields are still merged by default -
1017 equivalent to "@field merge".
1019 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1022 Fixed bug in zget for parameter ExtendedServicesResponse.
1026 --- 1.8.6 2002/03/25
1028 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1030 Client displays USR.1:SearchResult-1 (hits per term).
1032 Additional Search Info for search in Generic Frontend Server.
1034 Fixed CCL parsing of "field=s".
1036 WIN32 installer - using the excellent NSIS software from nullsoft.
1038 Fixed CCL parsing of "field = - <number>".
1040 Added function yaz_marc_decode that decodes MARC for line mode
1041 display or XML (similar to that used by JZKit).
1043 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1044 Z39.50. But ISO/ILL was, however.
1046 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1047 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1049 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1050 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1052 --- 1.8.5 2002/02/03
1054 New YAZ client features: Command completion and new commands:
1055 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1056 Code provided by Jacob Poulsen.
1058 New call oid_trav, that visits all registered OIDs via callback.
1060 Function ZOOM_record_get now returns const char pointer rather than
1061 void pointer. It saves a lot of type casts.
1063 For YAZ client, command "auth" now allows you to set authentication
1064 in IdPass style. It is enabled when three tokens are given - order
1065 is user, group and password.
1067 Fix memory leaks in MARC record handling for ZOOM.
1069 New option for YAZ client, -k <kilobytes> that sets
1070 maximum record size. Similar to -k option for generic frontend
1071 server and yaz-ztest.
1073 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1075 Prefix query parser reports "fail" when bad attribute set is given.
1077 Fix in MARC decoder. Proximity logging. Fix for attribute set
1078 in scan handler for server. Patches by Shigeru Ishida.
1080 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1083 Configure option --with-openssl=<dir> now works when a directory is
1084 specified. Patch provided by Morten Bøgeskov.
1086 New option for YAZ client, -u <auth>, that sets authentication.
1088 ZOOM fix: error information was sometimes "missing", since error
1089 was cleared/reset too when it shouldn't.
1091 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1093 --- 1.8.4 2002/01/04
1095 Scan for ZOOM API. New object ZOOM_scanset. New functions
1096 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1097 ZOOM_scanset_destroy.
1099 New ZOOM function, ZOOM_connection_last_event, that returns type
1100 of last event (such as "receive data", "send data", "apdu received",
1103 New ZOOM option, schema, that specifies schema for retrieval.
1105 New CCL feature. Qualifiers can be aliases for one or more
1106 other qualifiers (if more than one is given, OR is used).
1108 ZOOM uses named result sets if target supports it.
1110 Two new YAZ client commands: . (dot, which sources a script of YAZ
1111 client commands), and ! (to execute shell command.). Implemented
1114 Working on Debian packages.
1116 --- 1.8.3 2001/11/19
1118 YAZ client enables named result sets only if target supports it.
1120 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1122 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1123 with key="host" to get same result.
1125 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1126 Function Z3950_resultset_record(s) returns references to records
1127 "owned" by resultset. To become owner use Z3950_record_clone.
1129 Function z_ext_record handles Extended Services. Thanks to
1132 --- 1.8.2 2001/11/12
1134 CCL Parser fix: ignore token comma when dealing with and-lists.
1136 Documentation updates for COMSTACK.
1138 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1139 Changed prototype Z3950_records. For some functions, int parameters
1140 were changed to size_t.
1142 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1145 New MARC decode/display function, marc_display_exl, which properly rejects
1146 non-ISO2709 records. YAZ client uses it.
1148 --- 1.8.1 2001/10/29
1150 Fix bug: local attribute set wasn't set correctly in PQF strings.
1154 * Old Z39.50 codecs no longer supported.
1156 Added ZOOM C binding. See http://zoom.z3950.org/
1158 Renamed states for COMSTACKs to avoid confusion with events.
1160 Implemented cs_look and proper cs_rcvconnect.
1162 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1164 Configure detects POSIX threads on OpenBSD.
1166 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1167 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1169 When error is returned from present handler, non-surrogate diagnostic
1170 is returned in present response (and fetch handler is no longer called).
1172 * Minor adjustments to pquery parser (PQF). Token characters may be
1173 escaped by using backslash (C-style).
1175 PQF parser allows string attribute values to be specified. For @attr,
1176 non-numeric characters after the equal-sign are treated as strings
1177 (e.g. @attr 9=title).
1179 CCL trunction character may be defined (@truncation in file)
1181 * function zget_ExtendedServicesRequest sets waitAction to
1182 waitIfPossible (was wait).
1184 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1187 CCL operator names may be set in field definition files (CCL_bibset).
1188 See ccl/bib1 for an example.
1190 Fixes in ASN.1 compiler for C++ compatibility.
1192 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1193 and "op_or" to avoid conflict with C++.
1195 Fixed problem with GNU readline detection on Redhat 7.0.
1197 Added step-size for Scan backend handler.
1199 Fixed bug that made the frontend server crash when no attribute
1200 set was specified for scan.
1202 Front-end server automatically switches to original working directory
1203 when installed as an NT service. Previously -w had to be specified to
1206 Added extended attributes for retrieval module (data1), so that data1
1207 records carry d1_readXML/SGML attributes. d1_read also supports
1208 null-data rules ( <tag/>)
1210 On UNIX when POSIX threads are available, a separate library libyazthread
1211 is created. Programmers should link with that library and the yaz library
1212 when using threads. The reason for the split was that some applications
1213 on Linux, such as Apache, doesn't work well when using shared objects that
1216 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1217 (or any frontend server) in SSL mode by specifying ssl: followed by
1218 address. Only tested on UNIX.
1220 Added feature for CCL module. Virtual structure s=al or s=ol generates
1221 and-list and or-list respectively instead of phrase search.
1225 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1226 log_mask_str. This was done to avoid name conflicts with other libraries
1227 (such as other PHP extensions).
1229 Added raw OID member for preferred record syntax (request_format_raw)
1230 and returned record syntax (output_format_raw) for backend fetch method.
1232 Config file yaz-config now accepts options so that it returns specific
1233 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1235 Shared library support for UNIX using GNU libtool.
1237 * Modified backend interface. Request/Response struct's replaced by
1238 one read/write C struct. For example bend_fetchrequest and
1239 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1240 Every handler - even search has to be registered in bend_init
1241 handler. This means that the YAZ library no longer refers to
1242 external functions and it makes it possible to make the whole
1243 thing a single DLL/SO.
1245 Added Segment handler for backend server.
1247 Added Zmbol/Zebra administrative functions to YAZ client.
1249 Threaded frontend server on UNIX (when POSIX Threads are available).
1250 Starting the server with option -T enables multi-threading.
1254 Added configure option --enable-comp/disable-comp to control use
1255 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1256 located in sub directory asn.
1258 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1259 in ${exec_prefix}/bin along with the other programs yaz-client and
1262 GNU automake used to maintain makefiles.
1264 Added several OID's.
1266 Changed retrieval module so that we can load records with no abstract
1267 syntax defined. Tagpaths in these records are fully composed of string
1270 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1274 On UNIX, the generated makefile now supports a proper 'make install'.
1275 The prefix can be set via GNU configure to set the install location
1276 (default is /usr/local).
1278 * YAZ programs client and ztest were renamed to yaz-client and
1279 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1280 locations, such as /usr/bin,/usr/local/bin,etc.
1282 * YAZ Header files were moved from include to include/yaz. YAZ Header
1283 files are referred to as include <yaz/log.h> rather than <log.h>.
1284 The YAZ include path (-I ..) is therefore the same as before. Programmers
1285 should update their #include statements or use -Ipath/include/yaz
1286 instead. The main motivation for doing this change is that YAZ header files
1287 can be installed in "standard" locations /usr/include,/usr/local/include
1288 without introducing conflicts, since ALL YAZ header files are stored
1289 in subdirectory yaz (under /usr/include for example).
1291 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1292 rather than project/workspace files. We switched because project files
1293 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1296 Changed name of logging function, logf, to yaz_log, to prevent name
1297 clash with some math-log functions. The YAZ header log.h defines logf
1298 to yaz_log (#define) so there should be no incompatibilities by this
1301 Added bend_start/bend_stop handlers for server. These handler are
1302 called on start/stop of server. For windows they are called whenever
1303 a service is started/stopped.
1305 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1306 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1307 in util/yc.tcl. The auto-generated C code structures are, in a few
1308 cases, incompatible with the old decoders. There are differences in the
1309 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1310 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1311 The preprocessor variable ASN_COMPILED is defined when the compiled
1312 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1313 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1314 wish to use the old encoders/decoders you can specify --disable-yc
1317 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1318 version so that it supports both new - and old version of DB Update
1320 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1321 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1322 change. The name parameter can be set to 0 in which no name is specified
1323 for the construction. The macros odr_implicit and odr_explicit sets name
1324 parameter to zero for the construction involved. New macros
1325 odr_implicit_tag and odr_explicit_tag are similar to the others,
1326 except that a name parameter is added. For programmers' that don't use
1327 ODR they probably only need to change the call to z_APDU and z_External.
1329 Added access control facility by interfacing the TCP wrapper library.
1330 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1331 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1332 name of the daemon and enables the access control as specified in
1333 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1335 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1336 den Dool <H.M.vdnDool@kub.nl>.
1338 Added reference ID parameter to most functions in server API - refer
1339 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1341 Changed name of ccl library to libccl.a (was ccl.a).
1343 Fixed bug in decoder for Explain (Category TargetInfo).
1345 Added support for GNU readline in client. Thanks to Jacob Poulsen
1346 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1348 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1349 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1350 IMPLEMENTATION! This change was made to the development version before
1351 the ZIG decided to retract the amendment. If any users MUST be
1352 compatible with the original Update definition, PLEASE CONTACT US, and
1353 we will include a separate definition corresponding to the old Update
1354 ES. Note that because of the change to the ASN.1 of the
1355 TaskPackageRecordStructure we cannot define a single structure that
1356 will support both versions.
1358 * Added const modifier to buffer parameter for some ODR/BER encoding
1359 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1360 completeWAIS, odr_dumpBER.
1362 Fixed bug in client.c which caused a crash when a scanResponse didn't
1363 contain positionOfTerm.
1365 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1366 * will cause an error in a client if a non-YAZ target sends both a
1367 * list of Scan entries and non-surrogate diagnostics.
1369 Retrieval module enhancements. Tag sets may be typed in the reference
1370 to it. From the .abs-file the "tagset" directive takes a third optional
1371 integer type for the tag set referenced. From a .tag-file the "include"
1372 directive takes a third optional type as well. The old "type" directive
1373 in the tag set itself is still recognized but acts as the default type
1376 Backend interface change. Individual Scan terms returned from bend_scan
1377 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1378 in include/backend.h.
1380 Retrieval module enhancements. Multiple tag sets and attribute sets may
1381 be specified in abstract syntax specs. Revised the error/warning for
1382 logging messages reported by the retrieval module when reading the
1385 Object Identifier system (oid_..) changed. The API is backwards
1386 compatible but the oid-routines now allocates new OID's when needed.
1387 Raw OID's may be specified in oid_getvalbyname.
1389 YAZ now uses GNU configure to generate Makefile(s).
1391 * Minor changes in some of the member names of DeleteResultSetRequest and
1392 DeleteResultSetResponse. See include/proto.h.
1394 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1395 and added member 'languages' in TargetInfo (which was missing).
1397 Changed the way attribute sets are handled in the retrieval
1398 module. These are now cached, just like the abstract syntaxes
1401 Changed YAZ so that it links with compiled ASN.1.
1403 Added Explain-schema definitions and mapping routines. The following
1404 Explain categories have been implemented: AttributeDetails,
1405 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1407 Fixed minor bug in Windows version of Server Library.
1409 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1411 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1413 Added EXTERNAL: UNIverse Resource Report (non-standard).
1415 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1416 ENUMERATED and SET OF.
1418 * Added 'const' to some of the char pointer arguments for the
1419 functions, data1_read_node, data1_getelementbytagname,
1420 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1423 Fixed bug in data1_insert_taggeddata - the last_child member of
1424 parent wasn't initialised.
1426 * Changed data1_read_record and data1_read_node so that the supplied
1427 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1428 doesn't refer to any parts of the "SGML"-buffer.
1430 Fixed bug in server library (Windows version of statserv_remove).
1432 * Changed code so that it compiles as C++. The type definition
1433 of Odr_fun which is a member of Odr_arm was changed. The result is,
1434 that an explicit typecast is needed for the fun pointer when
1435 using Odr_arm - as in:
1436 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1438 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1440 Implemented the new structured date and time definition as approved
1441 by the ZIG. Added schemaId element to the specificTag in Espec-1
1442 (also approved at the last ZIG). Thanks to RVDM.
1444 Added some Object identifiers (RVDM).
1446 Changed the Update Extended Service (RVDM).
1448 Added command "refid" to client which specifies referenceId for
1449 the following requests.
1451 Implemented extended service handling for server. See ztest.c
1452 for an example as well as backend.h. New handlers are registerd
1453 in the Init handler.
1455 * Changed interface for sort in server.
1457 Added new members to statserv_options_block. It allows a server
1458 to read options from another source than just the command line. Thanks
1459 to Charles Woodfield.
1461 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1462 renamed to zboolean. Some C++ compilers complained about the name.
1464 Minor changes to gils.abs. Added index 's' (sort) on title
1465 and date/time-last-modified.
1467 --- 1.4pl2 1998/1/30
1469 Fixed bug in server library regarding inetd mode (-i). This bug
1470 was introduced by release 1.4.
1472 --- 1.4pl1 1998/1/29
1474 Added sort facility in client and backend server interface.
1476 Fixed problem with dependencies in Makefile(s).
1478 Fixed bugs for encoders/decoders of extended services and
1481 Implemented sub-tree feature for schemas. Sub-trees are
1482 referenced in *.abs-files. See explain.abs for an example
1483 of the use of this feature.
1485 Modified bib1.att; local attributes for ANY didn't include
1486 ANY itself (only affects use of the retrieval module).
1488 Fixed bug in plain SGML reader in function data1_read_node:
1489 tags with prefix "var" was incorrectly interpreted as variants.
1491 Added feature "sub-schemas" to enable references to - and definitions
1492 of - group of elements.
1494 * Removed member parent from type data1_element (in data1.h).
1496 Implemented function odr_nullval() that returns the value of
1499 * Removed member num_children from data1_node (in data1.h).
1501 Made NT service interface part of the server library. The
1502 function statserv_main uses the NT service when required and
1503 calls the statserv_start / statserv_close routines.
1505 Routine zget_SearchRequest and zget_PresentRequest fills
1506 resultSetName/Id member with "default" instead of "Default".
1508 Fixed memory leak in server. Request queue member wasn't freed.
1510 Fixed nmem_exit so that memory is freed.
1514 Revised the CCL parser utility to be thread safe.
1516 Added function, oid_ent_to_oid, to replace the function
1517 oid_getoidbyent, which is not thread safe.
1519 * Added nmem_init and nmem_exit to initialize and release
1520 NMEM resources. Function nmem_init should be called once in the
1521 initial thread before NMEM/ODR is used. statserv.c and client.c
1522 have been changed accordingly. The change was necessary to make
1523 NMEM thread safe. The NMEM memory pool is shared amongst threads
1524 in a process. Unix-based applications will still work fine without
1527 Added NT Services interface for the the Z39.50 (statserv) Server.
1528 Refer to the ztest.c source on the usage.
1530 Windows 95/NT port using MSVC5.0. Project files are included in the
1533 * Defined new 'global' handle for the retrieval (data1) system. The
1534 new handled, data1_handle, describes the state of the data1 system.
1535 This handle is passed as first argument to virtually all
1536 data1 related routines. The functions data1_create and data1_destroy
1537 creates and destroys a data1 handle respectively.
1539 Added ODR encode stream member to all backend request structures
1540 init, search, scan etc. This stream should be used to allocate all
1541 memory used for the response when thread safe operation is needed.
1543 Changed the comstack utility, cs_addstr, to be thread safe. The
1544 returned hostname string returned by the function is now part the
1547 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1548 function. The cs_straddr takes a COMSTACK handle as argument, so this
1549 function must be used after cs_create and before bind/connect.
1550 This function is thread safe.
1552 Moved test server to 'ztest' directory - generic server code still
1553 in 'server' directory.
1555 Made prefix query (pquery.c) utility thread safe.
1557 Added new function modifier YAZ_EXPORT to 'export' public DLL
1558 functions when using windows (see include/yconfig.h).
1560 Added definitions to the OID database (util/oid.c) (RVDM).
1562 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1564 Added call to ccl_rpn_delete in client program.
1566 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1567 release of RPN structure.
1569 Added support for C++, headers uses extern "C" for public definitions.
1570 With input from RVDM.
1572 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1573 Thanks to Ronald van der Meer (RVDM).
1575 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1577 Added support for private extensions to the OID database
1578 (oid_setprivateoids()). Thanks to RVDM.
1580 Added optional, physical ANY (key replication)
1582 Fixed null-reference problem in GRS-1 output filter.
1584 Proximity operator added to Prefix Query Format (PQF).
1586 In test client command "base" accepts multiple databases.
1588 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1592 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1594 Smallish bug-fixes in the new encoders/decoders (explain).
1596 Bug fixed in DeleteRequest.
1598 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1600 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1602 Added SOIF syntax (using private OID for now) to retrieval module and client.
1604 Added Update extended service.
1606 Added SearchResult-1 additional info structure.
1608 Added optional CCL (ISO8777) interpreter as separate module. Available
1611 --- 1.2 1996/6/10 (1st anniversary release)
1613 Added Summary record syntax. Lightly tested.
1615 Added OPAC record syntax. Untested.
1617 Added ResourceReport service encoders/decoders. Untested.
1619 Fixed bug in z_Unit - wrong tagging on unitSystem.
1621 Fixed bug in the DiagRecs decoder.
1623 Added options for max PDU size and session timeout to frontend-server.
1625 Added documentation of query-language parsers and other supporting utilities.
1627 [frontend-server] Added Attribute set to the bend_scanrequest API.
1629 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1630 surrogate diagnostics were generated.
1632 [retrieval] Allow multiple local values for attribute.
1634 [retrieval] Allow multiple attributes per element in .abs files. index type.
1636 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1638 --- 1.1pl2 1996/4/10
1640 Minor changes, mostly specific to Zebra's requirements (retrieval)
1644 Repaired bug in frontend server when running multiple listening
1645 endpoints in dynamic mode.
1647 z_External() now won't break if a known, ASN.1 value comes encapsulated
1648 in an octet-string. The value will pass through unmodified in an Odr_oct.
1650 Added a bit of code to the demo client to decode & display
1651 ASN.1-structured records represented in the octet-aligned branch of
1652 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1654 Added z_ext_getentbyref() to the ASN module. Doc updated.
1656 * Completed the SCAN definition in the ASN module. This may break SCAN
1657 code based on older YAZ-versions at compile-time. The fix is easy -
1660 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1661 under the SCAN definition. Remember to initialize this, server-people.
1663 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1664 that this does not extend to ODR and ASN.
1666 Comstack allows insertion of established socket (primarily for
1667 inetd-operation of servers). Doc updated.
1669 Front-end server can now start from the inetd in TCP mode. Doc
1672 --- 1.0pl4 1996/1/24
1676 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1677 the rank and record number.
1679 Adjustments to the frontend server.
1681 Fixed diagnostic BER dumper. It ignored the file argument.
1685 Various changes to retrieval module.
1687 Changed the union discriminators of the protocol files from enums to
1688 ints paired with #defines.
1690 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1693 *Changed operator in the RPN structure to 'roperator', again to avoid a
1696 Fixed problems in Explain decoders/encoders.
1698 --- 1.0pl2 1995/12/6
1700 Memory bug in log module fixed.
1702 --- 1.0pl1 1995/12/5
1704 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1706 Bug in Explain DatabaseInfo module fixed.
1708 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1712 The shift to v1.0 signals that we now consider the *core* functionality
1713 of YAZ reasonably stable (the core being more or less equivalent to
1714 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1715 tested (Explain not at all - though that will happen soonish).
1717 Minor changes to code to support Windows port.
1719 Various minor changes after we're getting to use GRS-1 & co. more.
1721 Added Espec-1 format.
1723 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1724 of the protocol and it cannot be selected when encoding (maps into 'string'
1725 when decoding). Needed to talk to some servers.
1727 Demo client can request simple element set names.
1729 Added Diagnostic Format encoders/decoders.
1731 Added simple Close handling to frontend server (no hooks for resource
1732 reporting yet), and demonstration client.
1734 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1736 --- 1.0b3 1995/08/24
1738 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1739 handled incorrectly when records were requested in the searchResponse. This
1740 will only affect you if you use the frontend-server.
1742 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1743 Test-client will ask for and print GRS1. Ztest will return dummy records
1746 Added Explain encoders/decoders to the service-level API. Untested.
1748 Added Extended Services: Item Order encoders and decoders to the Service-
1749 level API. Untested. We could use a recent copy of the pertinent bits
1750 of the ILL protocol to add those bits.
1752 Added diagnostic format 1 encoders/decoders to the service-level API.
1755 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1756 odr_cons.c, which causes a more correct output.
1758 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1759 was always set to 0 when no records were requested in the searchRequest.
1761 * Added better external-handling. This shouldn't harm old code that
1762 *encodes* externals. It can break code that looks for a
1763 'single-ASN1-type' representation, since those types that are known
1764 are now decoded immediately. Look at the SUTRS sample code in
1765 seshigh.c and client.c. Documentation updated.
1767 Handling of structured records in bend_fetchresponse. Length -1 marks
1768 structured record, type is deduced from format field.
1770 --- 1.0b2 1995/06/27
1771 Fairly quick maintenance release to add SUTRS support.
1773 Fixed handling of SUTRS records in the demonstration client.
1775 * Added format field to the bend_fetchrequest and bend_fetchresponce
1776 structures of the backend API (frontend server). When the record is
1777 returned, the value of the format field is mapped to an OID. The
1778 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1779 of the record. The special value VAL_NONE in the bend_request means
1780 that no specific format was requested by the client. Documentation
1781 updated accordingly. Test server (ztest) will return a fixed dummy
1782 SUTRS record if your client requests SUTRS.
1784 Documentation updated accordingly.
1786 You can now set external libraries and RANLIB support in the top-level
1790 First public release.
