3 Changed SRU update structure bend_update_rr so that SRU diagnostics are
4 stored in uri, message and details.. Previously diagnostics were stored
5 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
6 compatibility.. but he's probably the only one affected, so.
8 Added support for CCL, compiled on the client side, in ZOOM-C. This
9 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
10 input; the resulting query objects can be used for for searching with
11 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
13 YAZ' configure searches for OpenSSL by default.
15 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
16 SL_CTX_use_certificate_file. See
17 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
18 for more info. Thanks to Ko van der Sloot.
22 Bug #600: SRU GET, POST support for yaz-client. Introduced
23 command 'sru' which selects method SOAP/GET/POST.
25 Allow missingValueAction to be specified for the sortspec string -
26 function yaz_sort_spec. By default, the missing value action is null.
27 Use ! to specify "abort". Use = followed by stringvalue to specify default
30 Ensured that Present-handler (if defined) is called in GFS before any call to
31 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
32 searchRetrieve requests.
34 Documentation for YAZ is now based on the Docbook XML/XSLT using
35 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
36 is no longer depending on jade/openjade or docbook-to-man scripts.
37 PDF is no longer part of the distribution - but can optionally be
38 made using DSSSL/jadetex or FOP.
40 Added retrieval handling support in Generic Frontend Server to support
41 conversion between MARC/XML as well as XSLTtransforms. See
42 etc/yazgfs.xml for an example.
44 Added Authentication support to Generic Frontend Server in SRU
45 mode. Authentication using HTTP Basic is supported, as is the use
46 of 'x-username' and 'x-password' parameters in the request itself.
48 Added support for a new character set MARC8s identical to MARC8 except
49 that it converts combined characters to single Unicode characters in the
50 Latin-1 range (when possible).
54 ASN.1 compiler 0.4: generates brief Doxygen file header for
55 generated .h/.c files.
57 Utility yaz_iconv now supports conversion to MARC-8.
59 New facilities for the MARC module. The reading - and writing of
60 content are separate methods for the yaz_marc_t handle. The following
61 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
62 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
63 format). Write functions have prefix yaz_marc_write_.. The existing
64 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
65 available. Removed support for OAI-MARC and simplexml (not the
68 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
69 to be returned for this connection.
73 Allow multiple languages and charsets to be specified with
74 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
75 negcharset iso-8859-1,utf-8
77 Translation of proximity nodes from CQL into PQF now works.
79 Moved to automake 1.8, 1.9.
81 Added function yaz_log_set_handler which allows a log handler to be
82 installed. This handler will be called for all log messages. Output
83 to file is also produced; but that can be disabled by passing NULL
84 fname to yaz_log_init_file.
86 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
88 For SRW (including GFS), accept application/soap+xml as content-type
91 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
92 produces NO stylesheet reference even if a default stylesheet is specified
97 Updated Windows package to include yazd.dll + yazd.lib for the
98 Development component.
100 If the environment variable YAZ_LOG is set, then it is used as a
101 string indicating the default level of logging to use if not
102 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
103 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
104 used as before. So, for example, to omit warnings from YAZ logging,
107 cql_transform() now map structure and other attributes before indexes,
108 so that index-specific structures and other attributes can override
109 defaults. So now a combination of mapping specifications such as:
111 index.dc.date = 1=date-modified 4=5
112 does the right thing.
114 cql_transform() now also respects the "always" mapping specification,
115 which establishes an initial set of attributes to be used for all
116 terms except where overridden by more specific attributes associated
117 with the index, relation or modifier.
119 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
120 which mode to use; one of "post", "get" or "soap" (SRW, default).
122 Fixes for yaz_iconv routines: changed trie-based character set conversions
123 to use only non-negative values for bit fields due to Sun's C compiler not
124 supporting negative values.
126 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
127 sequences where not read correctly. Fix by Rustam Usmanov.
129 Updated win/makefile to use options, settings which makes things
130 compile with VS C 2005.
132 --- 2.1.12 2006/02/01
134 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
136 In ZOOM socket code, use select instead of poll on MacOSX.
138 ZOOM-C now support client-side compilation of CQL into RPN that is
139 sent to the server, enabling CQL to be used against all Z39.50
140 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
141 ZOOM_query object, and submit it using ZOOM_connection_search().
142 The CQL-to-RPN translation uses a configuration file, the name of
143 which must be specified in the Connection's "cqlfile" option.
145 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
146 function, which takes as its start-term parameter a ZOOM_query object
147 (which may have had either CQL or RPN set into it).
150 --- 2.1.10 2005/11/29
152 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
153 GFS to support this as well. Backend handler, bend_srw_update, does the
154 update work. Code contributed by Ko van der Sloot.
156 Allow retrieval of Search Result-1 information in ZOOM by the use of
157 options that are attached to a result set. ZOOM documentation updated
160 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
161 UTF-8 conversion. Patch by Raj Patel.
163 Added option -m to GFS to control formatting of timestamps in log file.
165 Added 'exit' as synonym for 'quit' in yaz-client
167 Added support for specifying SRW resultSetId + resultSetIdleTime in a
168 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
169 for the new members. Patch by Ko van der Sloot.
171 Added support for SRU POST. It is supported for content-type
172 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
174 Do not build the separate Multi-threaded (MT) library libyazthread.la.
175 Instead make the library libyaz.la multi-threaded. Threading as a whole
176 can still be disabled by configure option --disable-threads. Previosly,
177 with older GLIBCs there were problems with MT libs under Apache. This
178 has now been fixed a long time ago.
180 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
183 CQL module modified to be case insensitive for relations/indexes/operations.
185 Fixed bug in CQL transform code: incorrect value relationModifieder
188 Added 'show all' command for yaz-client which retrieves all results
191 Added new yaz-client, xmles, which takes a (private) OID and
192 a document to be sent as an extended service request.
194 Describe new yaz-client commands wait_response and set_auto_wait.
196 Increase TCP/IP listener backlog from 3 (which I am guessing was
197 copied from the SunOS manual entry way back when) so SOMAXCONN, so
198 that the socket will queue as many incoming connections as it's able
199 to handle ongoing connections. In other words, it will never now
200 refuse a connection that it would be able to handle merely because
201 it's not got around to accepting() enough of the pending connections
202 yet. This is the behaviour anyway under Linux, where the listen()
203 argument is ignored; but not under BSD and on systems such as
204 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
205 YAZ-based servers should now be uniform across operating systems in
208 yaz-marcdump uses 64-bit file access on some systems. This is enabled
209 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
210 This allows yaz-marcdump to read large MARC batches (>2 GB).
212 Modified all YAZ source files - except the source which is auto-generated
213 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
216 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
217 corresponding to the existing *_setl() function. These allow option
218 values containing arbitrary valuues.
220 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
221 ZOOM_resultset_sort() in new applications. Its behaviour is identical
222 except that it returns an indicator of whether or not the sort
223 criterion was accepted (0 for OK, -1 for invalid).
227 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
228 MARC output rather than returning "new" buffer.
230 yaz-client warns about unknown init options.
232 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
236 Added support for SRW sort in Generic Frontend Server. Patch
237 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
238 sortKeys - or NULL if none is provided.
240 Fixed bug #307: It was impossible to specify indefinite/no timeout
241 for ZOOM_event. Special timeout value -1 now means indefinite timeout
244 Added support for multiple languages and charsets to be specified in
245 ZOOM. Each charset/language is separated by a blank. If negotiation is
246 in effect in init-response, Option
247 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
248 Code based on patch by Vasiliy Osadchuk.
250 Fixed bug #306: infinite recursion that occurred when calling
251 yaz_log_level_init as the first call (before other log level or
254 Fixed bug in scan handling in front end server: if preferred-Position-In-
255 Response was non-present, a NULL pointer referece was performed.
259 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
260 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
261 now defined for all those error codes. So instead of putting 109 in
262 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
263 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
265 Modified the yaz-marcdump utility to skip garbage bytes between MARC
268 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
270 Program yaz-client now exits and produces an error message if multiple
271 Z39.50 servers are specified on the command line (none or one allowed
274 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
279 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
281 Fixed bug #272: Preserve spacing for CCL terms.
285 Added support for virtual hosts and multiple backend servers for
286 the YAZ frontend server. The configution is XML based and
287 support specificition of CQL to RPN mappings and explain information.
288 See section "Virtual Hosts" in the YAZ manual.
290 Extended OPAC display utility. OPAC display utility renders
291 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
292 to supplement yaz_marc_decode_wrbuf.
294 Fixed a bug in MARC decoder that could caused it to crash for some
295 invalid MARC records. More diagnostics and warnings where added in
296 XML output (warnings, etc are stored in comments).
298 --- 2.0.34 2005/02/08
300 Fixes for UNIX domain sockets. Bug #261.
302 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
304 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
305 Added yaz_marc_subfield_str which defines subfield lead string which is
306 used in YAZ_MARC_LINE format. Default string is blank+$. Added
307 yaz_marc_endline_str which defines end of fields string used in
308 YAZ_MARC_LINE format. Default string is newline.
310 Experimental support for MarcXChange. This format can be produced
311 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
312 http://www.bs.dk/standards/MarcXchange.xsd
314 Added yaz-client commands scansize that sets maximum number of
315 entries to be returned by scan.
317 --- 2.0.32 2005/01/11
319 Added support for SRW scan in yaz-client and Generic Frontend Server.
321 * Added whereInList member to SRW Scan Term.
323 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
325 Fixed NMEM system to return aligned blocks on the smallest boundaries
326 that are suitably aligned for all possible types on the particular
327 architecture YAZ is being built for.
329 --- 2.0.30 2005/01/04
331 Fixed numerious warnings that was issued with newer versions of GCC.
333 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
334 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
337 Make YAZ Generic Frontend Server slightly faster.
339 Enhance (and reduce) logging for Generic Frontend Server.
341 Revert YAZ log system so that it flushes every write operation
342 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
344 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
345 instead of LOG_, due to name clash with syslog(3). LOG_ are still
346 present. New applications should define YAZ_USE_NEW_LOG=1 - this
347 will effectively disable old definitions.
349 --- 2.0.28 2004/11/09
351 Added yaz_log_time_format which specifies log format using
354 Added yaz_log_module_level which returns mask for a module. Value
355 is non-zero mask a if module is enabled; zero if disabled.
357 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
358 in include/yaz/cql.h.
360 Fixed bug #176: Dont throw diagnostics on empty SRU args.
362 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
364 Fixed bug #172: RPM builds does not enable SSL.
366 Doxyfile.in part of dist. Doxyfile generated by configure.
368 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
369 are given and the corresponding component does not exist.
371 Extend CCL documentation in YAZ reference. Describe r=r.
373 --- 2.0.26 2004/10/01
375 Fixed MARC->MARCXML conversion to properly deal with
376 fields, subfields, indicators having non-ASCII characters.
378 Fixed MARC->MARCXML conversion so that ASCII control characters
379 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
382 Added YAZ GFS support for conversion from Z39.50 surrogate
383 diagnostics to SRW surrogate diagnostics.
385 Bug fix: YAZ GFS did not return schema in explainResponse.
387 --- 2.0.25 2004/09/30
389 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
390 now converts recordSchema to elementSetName as well as schema URI.
392 Fixed bug in COMSTACK that prevented HTTP request packages from being
395 --- 2.0.24 2004/09/29
397 Added CCL facility r=r "range" which is similar to r=o "ordered" but
398 does not require white-space before and after the dash in a range, e.g.
399 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
402 Fixed a few AC_TRY_LINK configure tests that did not operate properly
403 due to new GCC removing "redundant" code.
405 Added yaz-client commands scanpos and scanstep that sets preferred
406 position and step-size for scan.
408 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
410 Added CCL utility ccl_qual_buf which parses one or more CCL
411 spec lines in a buffer.
413 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
414 of name and value - ignoring empty lines and comments.
416 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
418 Added odr_get_element_path which returns current element path for an
419 ODR handle. This utility is useful in error handling or user-defined
422 Added ODR_PRINT utility odr_set_stream which is is a more generic
423 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
424 to a write function and pointer to close function. The close function - if
425 non-NULL - will be called during odr_destroy.
427 Fixed bug in CCL parser where truncation char was not removed from
428 right side when truncation=both was in effect.
430 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
433 --- 2.0.23 2004/08/11
435 Fix buffer overrun in CQL parser when dealing with proximity (%).
437 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
438 to UTF-8/UCS conversion is now only based on codetables.xml.
440 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
442 --- 2.0.22 2004/08/06
444 Add support for more "commit changes" in ZOOM (uses Extended Services).
446 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
449 Yet another small fix for configure of SSL.
451 --- 2.0.21 2004/05/14
453 Fix SSL libs for configure when --with-openssl=DIR is given.
455 --- 2.0.20 2004/05/10
457 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
459 SSL comstack now uses yaz.pem certificate file on server side
460 by default. Certificate filename can be configured by calling
461 comstack function cs_set_ssl_certificate_file before cs_bind is used.
463 Fix bug regarding multiple calls to ZOOM_connection_connect.
465 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
467 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
468 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
470 ZOOM now allows inspection of X509 peer certificate for verification.
471 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
473 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
474 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
475 as "modular" but it simplifies things.
477 Added cs_get_peer_certificate to that returns peer X509 PEM.
479 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
480 NULL if SSL is unavailable.
482 Documentation about MARC decoding tools.
484 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
486 --- 2.0.19 2004/03/30
488 Rename CHANGELOG to NEWS to follow GNU style packing.
490 Fix bug with missing initialization of member in init_diagnostics.
491 This bug affects threaded version of GFS server.
493 --- 2.0.18 2004/03/20
495 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
498 Ensure zlib.dll is packed with Windows install.
500 --- 2.0.17 2004/03/17
502 Fix encoding of xsd:string to use text instead of CDATA.
504 Fix endless loop in CQL parser with unbalanced ".
506 Use a more compact way to store MARC-8 conversion tables.
508 --- 2.0.16 2004/03/16 Debian only
510 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
513 Update CQL parser to use new CQL 1.1 modifiers for booleans and
518 --- 2.0.15 2004/03/01
520 Another fix for decoding of XML packed records.
522 --- 2.0.14 2004/02/25
524 Fixes for Chunked encoding. White space not ignored after length spec.
526 Update NS and use default NS for SRW diagnostic elements.
528 --- 2.0.13 2004/02/23
530 Implement ZOOM_resultset_cache_reset which resets record cache.
532 Implement ZOOM_resultset_sort which sorts a result set.
534 Implement chunked HTTP transfer.
536 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
538 --- 2.0.12 2004/02/16
540 Added member 'schema' to bend_explain_rr structure so that backend
541 can specify explain record identifier. Defaults to Zeerex 2.0.
543 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
545 --- 2.0.11 2004/02/16
547 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
550 Added init command for yaz-client which sends "extra" init request.
552 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
553 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
555 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
557 Make ZOOM error code for "invalid query".
559 Fixed compilation for SSL which wasn't properly enabled for all platforms.
561 --- 2.0.10 2004/02/05
563 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
566 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
568 Added option -p <file> to make Generic Frontend Server to write PID file.
570 Added option -D to put Generic Frontend Server in background on its own.
572 Make ZOOM C recognize option "password". If unset, "pass" is used
573 (for backwards compatibility).
575 Fixed a bug in Generic Frontend Server that could make it crash if a
576 client sets characterSetNegotation bit, but didn't pass negotiation stuff
579 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
580 Must be issued before open, in order to be in effect.
582 --- 2.0.9-6 2004/01/12 Debian/Windows
584 Make the SRU server more picky WRT unknown params, etc.
586 Bug fix: ZOOM scan response didn't return displayTerm - when present.
588 New YAZ client command, options, that sets Z39.50 options.
590 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
591 options from a string of tokens (one token for each option bit).
593 Update SRW diagnostic code messages.
595 --- 2.0.9-5 2004/01/07 Debian/Windows
597 Handle user defined stylesheet for SRW/SRU.
599 --- 2.0.9-4 2004/01/06 Debian/Windows
601 Fix bug in decoding of Content-Length.
603 --- 2.0.9-3 2004/01/06 Debian/Windows
605 Fix a bug with decoding of XML packed records.
607 --- 2.0.9-2 2004/01/05 Debian only
609 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
611 Fix bug in SRW/SRU diagnostics decoding.
615 Fixed bug in Generic Frontend Server which could drop records exceeding
616 preferred message size. Reported and fixed by Irina Dijour.
618 Fixed calculation of package size for structured records in Generic
619 Frontend Server. Reported and fixed by Irina Dijour.
621 Fixed namespace for SRW/SRU diagnostics.
623 Fixed SEGV in yaz-client that occured for HTTP connection errors.
627 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
628 this version is incompatible with version 1.0 and older YAZ SRW/SRU
631 CQL changes to reflect recent changes to the specification:
632 * Documentation talks about context sets instead of index sets.
633 * Documentation talks about indexes instead of qualifiers.
634 * The CQL-to-PQF transformer's configuration file now uses
635 "index.set.name = <attributes>" instead of the old form
636 "qualifier.set.name = <attributes>". (Both forms are still
637 understood but the latter is deprecated.)
638 * CQL terms with no explicit index specified are now interpreted as
639 cql.serverChoice instead of srw.serverChoice (which of course
640 behaves exactly the same.)
644 MARC conversion can now generate ISO2709 output in another
645 character set. yaz-marcdump uses this facility if you invoke it
648 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
649 functions from there can be used from C++.
653 Frontend server now transfers memory from decoded packages to stream
656 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
657 references to show up.
659 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
660 the ZOOM Abstract API. The older names for the same options are still
661 also supported for the benefit of old applications.
663 ZOOM-C supports "implementationId" and "implementationVersion" options
664 to go along with "implementationName". These allow the user code to
665 specify identification strings to be sent to servers.
666 Add OID for the new ExtLite attribute set.
668 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
669 as requested/supplid by Ere Maijala <ere@atp.fi>
671 For generic frontend server, reverse the order of
672 "toolkit-supplied / application-supplied" strings sent as implementationId,
673 Name and Version. Also, remove the spaces around the slash. This brings
674 the GFS in line with the behaviour of ZOOM-C on the client side.
676 Add function ZOOM_scanset_display_term.
678 yaz-client shows scan displayTerm if present.
680 Utility yaz-iconv is now installed by default along with the man page
683 Extend configure check for OpenSSL to use pkg-config where available (such
686 Incorporate patch by Morten Bogeskov which allows a Unix file socket
687 server to specify uid/gid/mask for socket using the format
688 unix:[user=uid,][group=gid,][umask=mask,]file=path
689 If file= is omitted the existing format is assumed, e.g.
691 in which case the mask is 0666 (rw for everybody).
693 Major restructure of YAZ source. All source in libyaz is in src directory.
694 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
695 util (utility programs such as ASN.1 compiler, yaz-marcdump).
697 Added man page for utility yaz-marcdump (used to be called marcdump).
698 yaz-marcdump is installed by 'make install'.
700 Fixed a memory leak in Generic Frontend Server that occurred when decoding
701 of incoming package failed.
703 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
705 Change prototype of odr_perror: add const to message string.
707 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
709 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
710 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
711 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
712 DNS lookup. There should not be any compatibility problems with this
713 assuming that blocking=1 or 0 is used.
715 Fix bad reference in UNIX comstack in function cs_addrstr.
717 Fix for compilation on AIX.
719 The generic front-end server (server/seshigh.c) now supports returning
720 Init diagnostics to the client in User-information-field, in
721 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
726 Allow any CQL relation (not just all,any,exact,scr).
728 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
729 that features the same UI.
731 Implemented command update0 in YAZ client which is equivalent to
732 update but uses old of Ext Update ASN.1.
734 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
735 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
736 Previously no OID was used for this info.
738 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
739 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
740 returns 'malformed search term' otherwise.
742 SortResponse member resultCount now set to NULL in sort handler of
745 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
748 Add three new utility functions for translating OIDs between various
749 formats -- symbolic name such as "Usmarc", minus-1-terminated int
750 arrays and dotted strings such as "1.2.840.10003.9.5.1":
751 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
752 char *oid_to_dotstring(const int *oid, char *oidbuf);
753 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
755 Reverted modifications for ES Update definition for z_IU0Update
756 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
757 is back to YAZ 2.0.2.
759 String value attributes for CCL parser.
761 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
762 which their FirstSearch server returns in Init responses, sometimes
763 carrying useful diagnostic information when Init fails. This has the
764 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
765 "z39.50/oclcui.asn", where its definition is somewhat different from
766 what OCLC document on their web-site, as required to interoperate with
769 Support for anonymous authentication in yaz-client. Use the command
772 * Fix the OID of the Index Data-local "admin" Extended Service from
773 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
774 the 1000, which indicates a locally-defined OID, was a mistake.
778 Fix CCL directive @case handling so that it affects string match for
779 both CCL keywords and qualifiers.
781 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
782 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
783 Decoder has been updated with ASN.1 changes as listed in
784 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
785 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
786 z_IUUpdate, remains unchanged.
788 ZOOM_record_get may now return a record in a specific character set.
789 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
790 "from" is the character set of record as returned by target. "to" is
791 the character set to be returned. If omitted, "to" is UTF-8.
793 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
795 New ODR utility, odr_getelement, which returns name of element for
796 which encoding/decoding failed.
798 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
799 in cases where a required element was omitted.
801 Bug fix: some MARC8 sequences were not converted.
803 New ZOOM option "step" which specifies number of records to be
804 retrieved in one chunk. Used in conjunction with "start" and "count".
806 SRW support for yaz-client. Use scheme http: to use it, e.g.
809 yaz-client no longer does (un)intelligent character set conversions
810 by default. Can be enabled with charset and marc_charset commands.
812 xmalloc trace fix for 64-bit systems such as DEC alpha.
814 Solaris 2.6 compile fix.
816 New function, cql_strerror() translates SRW error codes, as returned
817 by cql_transform_error(), into human-readable English strings. Used
818 in yaz-client diagnostics when appropriate.
820 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
821 converts it into a type-1 query which is sent to the server. This
822 makes CQL available for use with all Z-servers, as opposed to the tiny
823 minority that can handle CQL queries themselves.
827 New Debian package layout similar to the Redhat Package layout.
829 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
830 and search result respectively.
834 Redhat package is now several packages: libyaz (runtime libraries),
835 libyaz-devel (development and documentation, and yaz (utility programs).
836 Package spec file by Morten Bøgeskov.
838 New member 'schema' in struct bend_fetch_rr which the name of requested
839 schema (SRW/SRU) for record (or NULL if none was given). The fetch
840 handler MAY set this to reflect the schema of the returned record.
842 New member 'display_term' in struct scan_entry. GFS now sets member entries
843 and allocates scan entries to be filled by user scan handler. In previous
844 version, entries member was allocated by the scan handler. That still works,
845 but the GFS will ignore member display_term - assuming it was NOT set by
846 the handler. The fact that the GFS now allocates the entries both allows
847 for new members and makes a scan handler easier to write.
849 Fix CQL lex buffer overflow.
851 SRW/SRU recordPacking. For SRW default recordPacking is string. For
852 SRU default recordPacking is string.
854 SRU protocol support for frontend server.
856 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
858 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
860 Added scan for the ZOOM shell (zoomsh).
864 * String Identifers for Schemas (Amendment 5).
865 http://lcweb.loc.gov/z3950/agency/amend/am5.html
866 Old definition for schema
867 Odr_oid *schema; /* OPT */
872 Z_InternationalString *uri;
873 #define Z_Schema_oid 1
874 #define Z_Schema_uri 2
877 * resultCount parameter to Sort Response (Amendment 1).
878 http://lcweb.loc.gov/z3950/agency/amend/am1.html
880 Support for SRW 1.0 over HTTP. This is an optional feature and
881 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
884 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
885 on the same port. SRW SearchRetrieveRequests are mapped
886 to bend_init,bend_search,bend_fetch,bend_close.
888 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
890 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
891 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
893 ZOOM connections are SRW based if schem http is used for hostname
894 in connect, e.g. z = ZOOM_connection_new("http://myserver");
895 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
897 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
898 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
899 distance=n, order=true/false, relation=le, prox unit=word. If
900 n is omitted, distance 1 is used.
902 Fixed problem with C compiler include path in wrong order.
904 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
905 on Solaris. Patch from Ko van der Sloot.
907 New MARC decode API. All new functions operate on a yaz_marc_t
908 handle. The most important new functions are: yaz_marc_create,
909 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
910 decode and destroy respectively. Decoder can produce formats
911 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
912 include/yaz/marcdisp.h.
914 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
915 to UTF-8, UCS-32, wchar_t or Latin-1.
917 * Prototypes for yaz_iconv_-functions moved to separate header
918 include/yaz/yaz-iconv.h.
920 Make a few private functions 'static' in unix.c. This prevents
921 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
923 For ZOOM connection, the options targetImplementation{Id,Name,Version}
924 are set when Init Response is received.
926 New function ZOOM_connection_error_x similar to ZOOM_connection_error
927 but returns diagnostic set as well.
929 New function yaz_strerror which is a portable wrapper for
930 strerror/strerror_r/GetLastMessage.
932 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
933 is returned for MARC. If type is "oai", then OAI MARC is returned.
935 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
940 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
942 Fix bad race conditions on SIGTERM and terminate gracefully in
945 Move retrieval (data1) module to Zebra since nobody seems to be
948 Add GRS-1 render for ZOOM using same format as yaz-client.
952 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
954 Fix broken ESpec handling in data1 module.
956 SGML reader parses comments and makes them part of the data1 tree.
958 Added several type casts so that YAZ compiles as C++ code.
960 ZOOM didn't handle PDU encoding failures properly.
962 Added more Bib-1 diagnostics (approved extensions).
964 GNU configure: better check for iconv.
966 More portable use of accept, getpeername. Check for socklen_t. Use
967 int/size_t if socklen_t is not defined.
971 PQF parser rejects bad queries - including those with extra
972 characters in them. PQF parser used to silently ignore that.
973 Cleaner API for PQF added, which allows you to get detailed
974 error information for bad queries (see yaz/pquery.h).
976 Fixed bug in ZOOM_record_get for type "database".
978 Implemented mini iconv library supporting conversions between
979 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
981 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
985 Fixed ZOOM C record cache so that preferredRecordSyntax and
986 elementSetName is used to check for already fetched records.
990 Added three members in bend_initrequest structure to facilitate
991 character set negotiation.
993 Fixed a bug in frontend server that could cause indefinite
994 loops under rare conditions.
996 Revised character set utilities (charneg.h) so that encoding
997 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
999 For PQF, directive @term <type> sets term type for Scan/Search.
1000 Here <type> is general, string, numeric, null. The term type
1001 is inherited - just like @attr.
1003 New call odr_set_charset that sets character set conversion for
1004 international-strings on a ODR stream. Prototype is:
1005 int odr_set_charset(ODR o, const char *to, const char *from);
1006 The InternationalString is still represented as C string in YAZ
1007 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1008 won't). On the protocol level, you can use any encoding.
1010 Support for UNIX sockets in ZOOM.
1012 Solaris recv sometimes returns errno == ENOENT. It is treated as
1013 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1015 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1016 both client and server. Code by Morten Bøgeskov.
1018 --- 1.8.7 2002/05/22
1020 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1021 that they can be used directly from Visual Basic. You must recompile
1022 your windows APP if you're using ZOOM.
1024 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1025 Commands "lang" and "charset" sets language and character set respectively.
1026 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1027 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1029 Attributes from multiple CCL fields may be OR'ed rather than merged
1030 using directive "@field or". Fields are still merged by default -
1031 equivalent to "@field merge".
1033 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1036 Fixed bug in zget for parameter ExtendedServicesResponse.
1040 --- 1.8.6 2002/03/25
1042 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1044 Client displays USR.1:SearchResult-1 (hits per term).
1046 Additional Search Info for search in Generic Frontend Server.
1048 Fixed CCL parsing of "field=s".
1050 WIN32 installer - using the excellent NSIS software from nullsoft.
1052 Fixed CCL parsing of "field = - <number>".
1054 Added function yaz_marc_decode that decodes MARC for line mode
1055 display or XML (similar to that used by JZKit).
1057 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1058 Z39.50. But ISO/ILL was, however.
1060 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1061 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1063 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1064 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1066 --- 1.8.5 2002/02/03
1068 New YAZ client features: Command completion and new commands:
1069 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1070 Code provided by Jacob Poulsen.
1072 New call oid_trav, that visits all registered OIDs via callback.
1074 Function ZOOM_record_get now returns const char pointer rather than
1075 void pointer. It saves a lot of type casts.
1077 For YAZ client, command "auth" now allows you to set authentication
1078 in IdPass style. It is enabled when three tokens are given - order
1079 is user, group and password.
1081 Fix memory leaks in MARC record handling for ZOOM.
1083 New option for YAZ client, -k <kilobytes> that sets
1084 maximum record size. Similar to -k option for generic frontend
1085 server and yaz-ztest.
1087 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1089 Prefix query parser reports "fail" when bad attribute set is given.
1091 Fix in MARC decoder. Proximity logging. Fix for attribute set
1092 in scan handler for server. Patches by Shigeru Ishida.
1094 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1097 Configure option --with-openssl=<dir> now works when a directory is
1098 specified. Patch provided by Morten Bøgeskov.
1100 New option for YAZ client, -u <auth>, that sets authentication.
1102 ZOOM fix: error information was sometimes "missing", since error
1103 was cleared/reset too when it shouldn't.
1105 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1107 --- 1.8.4 2002/01/04
1109 Scan for ZOOM API. New object ZOOM_scanset. New functions
1110 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1111 ZOOM_scanset_destroy.
1113 New ZOOM function, ZOOM_connection_last_event, that returns type
1114 of last event (such as "receive data", "send data", "apdu received",
1117 New ZOOM option, schema, that specifies schema for retrieval.
1119 New CCL feature. Qualifiers can be aliases for one or more
1120 other qualifiers (if more than one is given, OR is used).
1122 ZOOM uses named result sets if target supports it.
1124 Two new YAZ client commands: . (dot, which sources a script of YAZ
1125 client commands), and ! (to execute shell command.). Implemented
1128 Working on Debian packages.
1130 --- 1.8.3 2001/11/19
1132 YAZ client enables named result sets only if target supports it.
1134 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1136 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1137 with key="host" to get same result.
1139 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1140 Function Z3950_resultset_record(s) returns references to records
1141 "owned" by resultset. To become owner use Z3950_record_clone.
1143 Function z_ext_record handles Extended Services. Thanks to
1146 --- 1.8.2 2001/11/12
1148 CCL Parser fix: ignore token comma when dealing with and-lists.
1150 Documentation updates for COMSTACK.
1152 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1153 Changed prototype Z3950_records. For some functions, int parameters
1154 were changed to size_t.
1156 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1159 New MARC decode/display function, marc_display_exl, which properly rejects
1160 non-ISO2709 records. YAZ client uses it.
1162 --- 1.8.1 2001/10/29
1164 Fix bug: local attribute set wasn't set correctly in PQF strings.
1168 * Old Z39.50 codecs no longer supported.
1170 Added ZOOM C binding. See http://zoom.z3950.org/
1172 Renamed states for COMSTACKs to avoid confusion with events.
1174 Implemented cs_look and proper cs_rcvconnect.
1176 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1178 Configure detects POSIX threads on OpenBSD.
1180 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1181 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1183 When error is returned from present handler, non-surrogate diagnostic
1184 is returned in present response (and fetch handler is no longer called).
1186 * Minor adjustments to pquery parser (PQF). Token characters may be
1187 escaped by using backslash (C-style).
1189 PQF parser allows string attribute values to be specified. For @attr,
1190 non-numeric characters after the equal-sign are treated as strings
1191 (e.g. @attr 9=title).
1193 CCL trunction character may be defined (@truncation in file)
1195 * function zget_ExtendedServicesRequest sets waitAction to
1196 waitIfPossible (was wait).
1198 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1201 CCL operator names may be set in field definition files (CCL_bibset).
1202 See ccl/bib1 for an example.
1204 Fixes in ASN.1 compiler for C++ compatibility.
1206 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1207 and "op_or" to avoid conflict with C++.
1209 Fixed problem with GNU readline detection on Redhat 7.0.
1211 Added step-size for Scan backend handler.
1213 Fixed bug that made the frontend server crash when no attribute
1214 set was specified for scan.
1216 Front-end server automatically switches to original working directory
1217 when installed as an NT service. Previously -w had to be specified to
1220 Added extended attributes for retrieval module (data1), so that data1
1221 records carry d1_readXML/SGML attributes. d1_read also supports
1222 null-data rules ( <tag/>)
1224 On UNIX when POSIX threads are available, a separate library libyazthread
1225 is created. Programmers should link with that library and the yaz library
1226 when using threads. The reason for the split was that some applications
1227 on Linux, such as Apache, doesn't work well when using shared objects that
1230 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1231 (or any frontend server) in SSL mode by specifying ssl: followed by
1232 address. Only tested on UNIX.
1234 Added feature for CCL module. Virtual structure s=al or s=ol generates
1235 and-list and or-list respectively instead of phrase search.
1239 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1240 log_mask_str. This was done to avoid name conflicts with other libraries
1241 (such as other PHP extensions).
1243 Added raw OID member for preferred record syntax (request_format_raw)
1244 and returned record syntax (output_format_raw) for backend fetch method.
1246 Config file yaz-config now accepts options so that it returns specific
1247 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1249 Shared library support for UNIX using GNU libtool.
1251 * Modified backend interface. Request/Response struct's replaced by
1252 one read/write C struct. For example bend_fetchrequest and
1253 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1254 Every handler - even search has to be registered in bend_init
1255 handler. This means that the YAZ library no longer refers to
1256 external functions and it makes it possible to make the whole
1257 thing a single DLL/SO.
1259 Added Segment handler for backend server.
1261 Added Zmbol/Zebra administrative functions to YAZ client.
1263 Threaded frontend server on UNIX (when POSIX Threads are available).
1264 Starting the server with option -T enables multi-threading.
1268 Added configure option --enable-comp/disable-comp to control use
1269 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1270 located in sub directory asn.
1272 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1273 in ${exec_prefix}/bin along with the other programs yaz-client and
1276 GNU automake used to maintain makefiles.
1278 Added several OID's.
1280 Changed retrieval module so that we can load records with no abstract
1281 syntax defined. Tagpaths in these records are fully composed of string
1284 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1288 On UNIX, the generated makefile now supports a proper 'make install'.
1289 The prefix can be set via GNU configure to set the install location
1290 (default is /usr/local).
1292 * YAZ programs client and ztest were renamed to yaz-client and
1293 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1294 locations, such as /usr/bin,/usr/local/bin,etc.
1296 * YAZ Header files were moved from include to include/yaz. YAZ Header
1297 files are referred to as include <yaz/log.h> rather than <log.h>.
1298 The YAZ include path (-I ..) is therefore the same as before. Programmers
1299 should update their #include statements or use -Ipath/include/yaz
1300 instead. The main motivation for doing this change is that YAZ header files
1301 can be installed in "standard" locations /usr/include,/usr/local/include
1302 without introducing conflicts, since ALL YAZ header files are stored
1303 in subdirectory yaz (under /usr/include for example).
1305 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1306 rather than project/workspace files. We switched because project files
1307 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1310 Changed name of logging function, logf, to yaz_log, to prevent name
1311 clash with some math-log functions. The YAZ header log.h defines logf
1312 to yaz_log (#define) so there should be no incompatibilities by this
1315 Added bend_start/bend_stop handlers for server. These handler are
1316 called on start/stop of server. For windows they are called whenever
1317 a service is started/stopped.
1319 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1320 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1321 in util/yc.tcl. The auto-generated C code structures are, in a few
1322 cases, incompatible with the old decoders. There are differences in the
1323 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1324 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1325 The preprocessor variable ASN_COMPILED is defined when the compiled
1326 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1327 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1328 wish to use the old encoders/decoders you can specify --disable-yc
1331 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1332 version so that it supports both new - and old version of DB Update
1334 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1335 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1336 change. The name parameter can be set to 0 in which no name is specified
1337 for the construction. The macros odr_implicit and odr_explicit sets name
1338 parameter to zero for the construction involved. New macros
1339 odr_implicit_tag and odr_explicit_tag are similar to the others,
1340 except that a name parameter is added. For programmers' that don't use
1341 ODR they probably only need to change the call to z_APDU and z_External.
1343 Added access control facility by interfacing the TCP wrapper library.
1344 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1345 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1346 name of the daemon and enables the access control as specified in
1347 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1349 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1350 den Dool <H.M.vdnDool@kub.nl>.
1352 Added reference ID parameter to most functions in server API - refer
1353 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1355 Changed name of ccl library to libccl.a (was ccl.a).
1357 Fixed bug in decoder for Explain (Category TargetInfo).
1359 Added support for GNU readline in client. Thanks to Jacob Poulsen
1360 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1362 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1363 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1364 IMPLEMENTATION! This change was made to the development version before
1365 the ZIG decided to retract the amendment. If any users MUST be
1366 compatible with the original Update definition, PLEASE CONTACT US, and
1367 we will include a separate definition corresponding to the old Update
1368 ES. Note that because of the change to the ASN.1 of the
1369 TaskPackageRecordStructure we cannot define a single structure that
1370 will support both versions.
1372 * Added const modifier to buffer parameter for some ODR/BER encoding
1373 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1374 completeWAIS, odr_dumpBER.
1376 Fixed bug in client.c which caused a crash when a scanResponse didn't
1377 contain positionOfTerm.
1379 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1380 * will cause an error in a client if a non-YAZ target sends both a
1381 * list of Scan entries and non-surrogate diagnostics.
1383 Retrieval module enhancements. Tag sets may be typed in the reference
1384 to it. From the .abs-file the "tagset" directive takes a third optional
1385 integer type for the tag set referenced. From a .tag-file the "include"
1386 directive takes a third optional type as well. The old "type" directive
1387 in the tag set itself is still recognized but acts as the default type
1390 Backend interface change. Individual Scan terms returned from bend_scan
1391 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1392 in include/backend.h.
1394 Retrieval module enhancements. Multiple tag sets and attribute sets may
1395 be specified in abstract syntax specs. Revised the error/warning for
1396 logging messages reported by the retrieval module when reading the
1399 Object Identifier system (oid_..) changed. The API is backwards
1400 compatible but the oid-routines now allocates new OID's when needed.
1401 Raw OID's may be specified in oid_getvalbyname.
1403 YAZ now uses GNU configure to generate Makefile(s).
1405 * Minor changes in some of the member names of DeleteResultSetRequest and
1406 DeleteResultSetResponse. See include/proto.h.
1408 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1409 and added member 'languages' in TargetInfo (which was missing).
1411 Changed the way attribute sets are handled in the retrieval
1412 module. These are now cached, just like the abstract syntaxes
1415 Changed YAZ so that it links with compiled ASN.1.
1417 Added Explain-schema definitions and mapping routines. The following
1418 Explain categories have been implemented: AttributeDetails,
1419 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1421 Fixed minor bug in Windows version of Server Library.
1423 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1425 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1427 Added EXTERNAL: UNIverse Resource Report (non-standard).
1429 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1430 ENUMERATED and SET OF.
1432 * Added 'const' to some of the char pointer arguments for the
1433 functions, data1_read_node, data1_getelementbytagname,
1434 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1437 Fixed bug in data1_insert_taggeddata - the last_child member of
1438 parent wasn't initialised.
1440 * Changed data1_read_record and data1_read_node so that the supplied
1441 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1442 doesn't refer to any parts of the "SGML"-buffer.
1444 Fixed bug in server library (Windows version of statserv_remove).
1446 * Changed code so that it compiles as C++. The type definition
1447 of Odr_fun which is a member of Odr_arm was changed. The result is,
1448 that an explicit typecast is needed for the fun pointer when
1449 using Odr_arm - as in:
1450 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1452 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1454 Implemented the new structured date and time definition as approved
1455 by the ZIG. Added schemaId element to the specificTag in Espec-1
1456 (also approved at the last ZIG). Thanks to RVDM.
1458 Added some Object identifiers (RVDM).
1460 Changed the Update Extended Service (RVDM).
1462 Added command "refid" to client which specifies referenceId for
1463 the following requests.
1465 Implemented extended service handling for server. See ztest.c
1466 for an example as well as backend.h. New handlers are registerd
1467 in the Init handler.
1469 * Changed interface for sort in server.
1471 Added new members to statserv_options_block. It allows a server
1472 to read options from another source than just the command line. Thanks
1473 to Charles Woodfield.
1475 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1476 renamed to zboolean. Some C++ compilers complained about the name.
1478 Minor changes to gils.abs. Added index 's' (sort) on title
1479 and date/time-last-modified.
1481 --- 1.4pl2 1998/1/30
1483 Fixed bug in server library regarding inetd mode (-i). This bug
1484 was introduced by release 1.4.
1486 --- 1.4pl1 1998/1/29
1488 Added sort facility in client and backend server interface.
1490 Fixed problem with dependencies in Makefile(s).
1492 Fixed bugs for encoders/decoders of extended services and
1495 Implemented sub-tree feature for schemas. Sub-trees are
1496 referenced in *.abs-files. See explain.abs for an example
1497 of the use of this feature.
1499 Modified bib1.att; local attributes for ANY didn't include
1500 ANY itself (only affects use of the retrieval module).
1502 Fixed bug in plain SGML reader in function data1_read_node:
1503 tags with prefix "var" was incorrectly interpreted as variants.
1505 Added feature "sub-schemas" to enable references to - and definitions
1506 of - group of elements.
1508 * Removed member parent from type data1_element (in data1.h).
1510 Implemented function odr_nullval() that returns the value of
1513 * Removed member num_children from data1_node (in data1.h).
1515 Made NT service interface part of the server library. The
1516 function statserv_main uses the NT service when required and
1517 calls the statserv_start / statserv_close routines.
1519 Routine zget_SearchRequest and zget_PresentRequest fills
1520 resultSetName/Id member with "default" instead of "Default".
1522 Fixed memory leak in server. Request queue member wasn't freed.
1524 Fixed nmem_exit so that memory is freed.
1528 Revised the CCL parser utility to be thread safe.
1530 Added function, oid_ent_to_oid, to replace the function
1531 oid_getoidbyent, which is not thread safe.
1533 * Added nmem_init and nmem_exit to initialize and release
1534 NMEM resources. Function nmem_init should be called once in the
1535 initial thread before NMEM/ODR is used. statserv.c and client.c
1536 have been changed accordingly. The change was necessary to make
1537 NMEM thread safe. The NMEM memory pool is shared amongst threads
1538 in a process. Unix-based applications will still work fine without
1541 Added NT Services interface for the the Z39.50 (statserv) Server.
1542 Refer to the ztest.c source on the usage.
1544 Windows 95/NT port using MSVC5.0. Project files are included in the
1547 * Defined new 'global' handle for the retrieval (data1) system. The
1548 new handled, data1_handle, describes the state of the data1 system.
1549 This handle is passed as first argument to virtually all
1550 data1 related routines. The functions data1_create and data1_destroy
1551 creates and destroys a data1 handle respectively.
1553 Added ODR encode stream member to all backend request structures
1554 init, search, scan etc. This stream should be used to allocate all
1555 memory used for the response when thread safe operation is needed.
1557 Changed the comstack utility, cs_addstr, to be thread safe. The
1558 returned hostname string returned by the function is now part the
1561 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1562 function. The cs_straddr takes a COMSTACK handle as argument, so this
1563 function must be used after cs_create and before bind/connect.
1564 This function is thread safe.
1566 Moved test server to 'ztest' directory - generic server code still
1567 in 'server' directory.
1569 Made prefix query (pquery.c) utility thread safe.
1571 Added new function modifier YAZ_EXPORT to 'export' public DLL
1572 functions when using windows (see include/yconfig.h).
1574 Added definitions to the OID database (util/oid.c) (RVDM).
1576 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1578 Added call to ccl_rpn_delete in client program.
1580 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1581 release of RPN structure.
1583 Added support for C++, headers uses extern "C" for public definitions.
1584 With input from RVDM.
1586 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1587 Thanks to Ronald van der Meer (RVDM).
1589 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1591 Added support for private extensions to the OID database
1592 (oid_setprivateoids()). Thanks to RVDM.
1594 Added optional, physical ANY (key replication)
1596 Fixed null-reference problem in GRS-1 output filter.
1598 Proximity operator added to Prefix Query Format (PQF).
1600 In test client command "base" accepts multiple databases.
1602 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1606 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1608 Smallish bug-fixes in the new encoders/decoders (explain).
1610 Bug fixed in DeleteRequest.
1612 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1614 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1616 Added SOIF syntax (using private OID for now) to retrieval module and client.
1618 Added Update extended service.
1620 Added SearchResult-1 additional info structure.
1622 Added optional CCL (ISO8777) interpreter as separate module. Available
1625 --- 1.2 1996/6/10 (1st anniversary release)
1627 Added Summary record syntax. Lightly tested.
1629 Added OPAC record syntax. Untested.
1631 Added ResourceReport service encoders/decoders. Untested.
1633 Fixed bug in z_Unit - wrong tagging on unitSystem.
1635 Fixed bug in the DiagRecs decoder.
1637 Added options for max PDU size and session timeout to frontend-server.
1639 Added documentation of query-language parsers and other supporting utilities.
1641 [frontend-server] Added Attribute set to the bend_scanrequest API.
1643 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1644 surrogate diagnostics were generated.
1646 [retrieval] Allow multiple local values for attribute.
1648 [retrieval] Allow multiple attributes per element in .abs files. index type.
1650 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1652 --- 1.1pl2 1996/4/10
1654 Minor changes, mostly specific to Zebra's requirements (retrieval)
1658 Repaired bug in frontend server when running multiple listening
1659 endpoints in dynamic mode.
1661 z_External() now won't break if a known, ASN.1 value comes encapsulated
1662 in an octet-string. The value will pass through unmodified in an Odr_oct.
1664 Added a bit of code to the demo client to decode & display
1665 ASN.1-structured records represented in the octet-aligned branch of
1666 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1668 Added z_ext_getentbyref() to the ASN module. Doc updated.
1670 * Completed the SCAN definition in the ASN module. This may break SCAN
1671 code based on older YAZ-versions at compile-time. The fix is easy -
1674 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1675 under the SCAN definition. Remember to initialize this, server-people.
1677 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1678 that this does not extend to ODR and ASN.
1680 Comstack allows insertion of established socket (primarily for
1681 inetd-operation of servers). Doc updated.
1683 Front-end server can now start from the inetd in TCP mode. Doc
1686 --- 1.0pl4 1996/1/24
1690 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1691 the rank and record number.
1693 Adjustments to the frontend server.
1695 Fixed diagnostic BER dumper. It ignored the file argument.
1699 Various changes to retrieval module.
1701 Changed the union discriminators of the protocol files from enums to
1702 ints paired with #defines.
1704 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1707 *Changed operator in the RPN structure to 'roperator', again to avoid a
1710 Fixed problems in Explain decoders/encoders.
1712 --- 1.0pl2 1995/12/6
1714 Memory bug in log module fixed.
1716 --- 1.0pl1 1995/12/5
1718 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1720 Bug in Explain DatabaseInfo module fixed.
1722 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1726 The shift to v1.0 signals that we now consider the *core* functionality
1727 of YAZ reasonably stable (the core being more or less equivalent to
1728 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1729 tested (Explain not at all - though that will happen soonish).
1731 Minor changes to code to support Windows port.
1733 Various minor changes after we're getting to use GRS-1 & co. more.
1735 Added Espec-1 format.
1737 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1738 of the protocol and it cannot be selected when encoding (maps into 'string'
1739 when decoding). Needed to talk to some servers.
1741 Demo client can request simple element set names.
1743 Added Diagnostic Format encoders/decoders.
1745 Added simple Close handling to frontend server (no hooks for resource
1746 reporting yet), and demonstration client.
1748 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1750 --- 1.0b3 1995/08/24
1752 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1753 handled incorrectly when records were requested in the searchResponse. This
1754 will only affect you if you use the frontend-server.
1756 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1757 Test-client will ask for and print GRS1. Ztest will return dummy records
1760 Added Explain encoders/decoders to the service-level API. Untested.
1762 Added Extended Services: Item Order encoders and decoders to the Service-
1763 level API. Untested. We could use a recent copy of the pertinent bits
1764 of the ILL protocol to add those bits.
1766 Added diagnostic format 1 encoders/decoders to the service-level API.
1769 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1770 odr_cons.c, which causes a more correct output.
1772 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1773 was always set to 0 when no records were requested in the searchRequest.
1775 * Added better external-handling. This shouldn't harm old code that
1776 *encodes* externals. It can break code that looks for a
1777 'single-ASN1-type' representation, since those types that are known
1778 are now decoded immediately. Look at the SUTRS sample code in
1779 seshigh.c and client.c. Documentation updated.
1781 Handling of structured records in bend_fetchresponse. Length -1 marks
1782 structured record, type is deduced from format field.
1784 --- 1.0b2 1995/06/27
1785 Fairly quick maintenance release to add SUTRS support.
1787 Fixed handling of SUTRS records in the demonstration client.
1789 * Added format field to the bend_fetchrequest and bend_fetchresponce
1790 structures of the backend API (frontend server). When the record is
1791 returned, the value of the format field is mapped to an OID. The
1792 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1793 of the record. The special value VAL_NONE in the bend_request means
1794 that no specific format was requested by the client. Documentation
1795 updated accordingly. Test server (ztest) will return a fixed dummy
1796 SUTRS record if your client requests SUTRS.
1798 Documentation updated accordingly.
1800 You can now set external libraries and RANLIB support in the top-level
1804 First public release.
