3 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
6 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
8 New option for yaz-marcdump -lpos=value which allows setting a portion
9 of MARC header to a certain value.
11 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
13 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
14 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
18 Fixed problem with SRU mode type (soap, get, post) for yaz-client
21 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
25 Fixed MARC ISO2709 encoding routines to deal with character set
28 Minor changes to GFS logging. Database included in search request log
31 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
32 cached/multiple records.
34 Shared libraries are built by default on Unix+configure.
36 Changed cql2pqf transformation to use a different evaluation order. The
37 new order is: always, relation, structure, position, truncation, index
38 and relationModifier. Old order was: always, relation, relationModifier,
39 structure, index, position, truncation. Note that the the latter ones
40 override former ones for identical attributes.. The new scheme means that
41 it is possible to override any existing attribute with a relationModifier.
42 And also that it is possible to override everything for the index rule
43 (except the ones listed in relationModifier). No order is perfect but this
44 one, we believe, covers more real cases.. The "always" should have been
45 called "default", since the attributes there can be overridden with all
48 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
49 compilation phase, but also for yaz-config --cflags output. This allows
50 us to have public headers with Libxml2 stuff in them . It should also,
51 eventually, make Libxml2 checks redundant in packages using YAZ, such
56 Changed SRU update structure bend_update_rr so that SRU diagnostics are
57 stored in uri, message and details.. Previously diagnostics were stored
58 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
59 compatibility.. but he's probably the only one affected, so.
61 Added support for CCL, compiled on the client side, in ZOOM-C. This
62 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
63 input; the resulting query objects can be used for for searching with
64 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
66 YAZ' configure searches for OpenSSL by default.
68 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
69 SL_CTX_use_certificate_file. See
70 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
71 for more info. Thanks to Ko van der Sloot.
75 Bug #600: SRU GET, POST support for yaz-client. Introduced
76 command 'sru' which selects method SOAP/GET/POST.
78 Allow missingValueAction to be specified for the sortspec string -
79 function yaz_sort_spec. By default, the missing value action is null.
80 Use ! to specify "abort". Use = followed by stringvalue to specify default
83 Ensured that Present-handler (if defined) is called in GFS before any call to
84 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
85 searchRetrieve requests.
87 Documentation for YAZ is now based on the Docbook XML/XSLT using
88 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
89 is no longer depending on jade/openjade or docbook-to-man scripts.
90 PDF is no longer part of the distribution - but can optionally be
91 made using DSSSL/jadetex or FOP.
93 Added retrieval handling support in Generic Frontend Server to support
94 conversion between MARC/XML as well as XSLTtransforms. See
95 etc/yazgfs.xml for an example.
97 Added Authentication support to Generic Frontend Server in SRU
98 mode. Authentication using HTTP Basic is supported, as is the use
99 of 'x-username' and 'x-password' parameters in the request itself.
101 Added support for a new character set MARC8s identical to MARC8 except
102 that it converts combined characters to single Unicode characters in the
103 Latin-1 range (when possible).
105 --- 2.1.18 2006/04/24
107 ASN.1 compiler 0.4: generates brief Doxygen file header for
108 generated .h/.c files.
110 Utility yaz_iconv now supports conversion to MARC-8.
112 New facilities for the MARC module. The reading - and writing of
113 content are separate methods for the yaz_marc_t handle. The following
114 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
115 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
116 format). Write functions have prefix yaz_marc_write_.. The existing
117 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
118 available. Removed support for OAI-MARC and simplexml (not the
119 simplexml from PHP5).
121 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
122 to be returned for this connection.
124 --- 2.1.16 2006/03/31
126 Allow multiple languages and charsets to be specified with
127 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
128 negcharset iso-8859-1,utf-8
130 Translation of proximity nodes from CQL into PQF now works.
132 Moved to automake 1.8, 1.9.
134 Added function yaz_log_set_handler which allows a log handler to be
135 installed. This handler will be called for all log messages. Output
136 to file is also produced; but that can be disabled by passing NULL
137 fname to yaz_log_init_file.
139 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
141 For SRW (including GFS), accept application/soap+xml as content-type
144 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
145 produces NO stylesheet reference even if a default stylesheet is specified
148 --- 2.1.14 2006/03/14
150 Updated Windows package to include yazd.dll + yazd.lib for the
151 Development component.
153 If the environment variable YAZ_LOG is set, then it is used as a
154 string indicating the default level of logging to use if not
155 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
156 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
157 used as before. So, for example, to omit warnings from YAZ logging,
160 cql_transform() now map structure and other attributes before indexes,
161 so that index-specific structures and other attributes can override
162 defaults. So now a combination of mapping specifications such as:
164 index.dc.date = 1=date-modified 4=5
165 does the right thing.
167 cql_transform() now also respects the "always" mapping specification,
168 which establishes an initial set of attributes to be used for all
169 terms except where overridden by more specific attributes associated
170 with the index, relation or modifier.
172 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
173 which mode to use; one of "post", "get" or "soap" (SRW, default).
175 Fixes for yaz_iconv routines: changed trie-based character set conversions
176 to use only non-negative values for bit fields due to Sun's C compiler not
177 supporting negative values.
179 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
180 sequences where not read correctly. Fix by Rustam Usmanov.
182 Updated win/makefile to use options, settings which makes things
183 compile with VS C 2005.
185 --- 2.1.12 2006/02/01
187 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
189 In ZOOM socket code, use select instead of poll on MacOSX.
191 ZOOM-C now support client-side compilation of CQL into RPN that is
192 sent to the server, enabling CQL to be used against all Z39.50
193 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
194 ZOOM_query object, and submit it using ZOOM_connection_search().
195 The CQL-to-RPN translation uses a configuration file, the name of
196 which must be specified in the Connection's "cqlfile" option.
198 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
199 function, which takes as its start-term parameter a ZOOM_query object
200 (which may have had either CQL or RPN set into it).
203 --- 2.1.10 2005/11/29
205 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
206 GFS to support this as well. Backend handler, bend_srw_update, does the
207 update work. Code contributed by Ko van der Sloot.
209 Allow retrieval of Search Result-1 information in ZOOM by the use of
210 options that are attached to a result set. ZOOM documentation updated
213 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
214 UTF-8 conversion. Patch by Raj Patel.
216 Added option -m to GFS to control formatting of timestamps in log file.
218 Added 'exit' as synonym for 'quit' in yaz-client
220 Added support for specifying SRW resultSetId + resultSetIdleTime in a
221 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
222 for the new members. Patch by Ko van der Sloot.
224 Added support for SRU POST. It is supported for content-type
225 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
227 Do not build the separate Multi-threaded (MT) library libyazthread.la.
228 Instead make the library libyaz.la multi-threaded. Threading as a whole
229 can still be disabled by configure option --disable-threads. Previosly,
230 with older GLIBCs there were problems with MT libs under Apache. This
231 has now been fixed a long time ago.
233 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
236 CQL module modified to be case insensitive for relations/indexes/operations.
238 Fixed bug in CQL transform code: incorrect value relationModifieder
241 Added 'show all' command for yaz-client which retrieves all results
244 Added new yaz-client, xmles, which takes a (private) OID and
245 a document to be sent as an extended service request.
247 Describe new yaz-client commands wait_response and set_auto_wait.
249 Increase TCP/IP listener backlog from 3 (which I am guessing was
250 copied from the SunOS manual entry way back when) so SOMAXCONN, so
251 that the socket will queue as many incoming connections as it's able
252 to handle ongoing connections. In other words, it will never now
253 refuse a connection that it would be able to handle merely because
254 it's not got around to accepting() enough of the pending connections
255 yet. This is the behaviour anyway under Linux, where the listen()
256 argument is ignored; but not under BSD and on systems such as
257 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
258 YAZ-based servers should now be uniform across operating systems in
261 yaz-marcdump uses 64-bit file access on some systems. This is enabled
262 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
263 This allows yaz-marcdump to read large MARC batches (>2 GB).
265 Modified all YAZ source files - except the source which is auto-generated
266 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
269 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
270 corresponding to the existing *_setl() function. These allow option
271 values containing arbitrary valuues.
273 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
274 ZOOM_resultset_sort() in new applications. Its behaviour is identical
275 except that it returns an indicator of whether or not the sort
276 criterion was accepted (0 for OK, -1 for invalid).
280 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
281 MARC output rather than returning "new" buffer.
283 yaz-client warns about unknown init options.
285 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
289 Added support for SRW sort in Generic Frontend Server. Patch
290 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
291 sortKeys - or NULL if none is provided.
293 Fixed bug #307: It was impossible to specify indefinite/no timeout
294 for ZOOM_event. Special timeout value -1 now means indefinite timeout
297 Added support for multiple languages and charsets to be specified in
298 ZOOM. Each charset/language is separated by a blank. If negotiation is
299 in effect in init-response, Option
300 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
301 Code based on patch by Vasiliy Osadchuk.
303 Fixed bug #306: infinite recursion that occurred when calling
304 yaz_log_level_init as the first call (before other log level or
307 Fixed bug in scan handling in front end server: if preferred-Position-In-
308 Response was non-present, a NULL pointer referece was performed.
312 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
313 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
314 now defined for all those error codes. So instead of putting 109 in
315 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
316 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
318 Modified the yaz-marcdump utility to skip garbage bytes between MARC
321 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
323 Program yaz-client now exits and produces an error message if multiple
324 Z39.50 servers are specified on the command line (none or one allowed
327 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
332 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
334 Fixed bug #272: Preserve spacing for CCL terms.
338 Added support for virtual hosts and multiple backend servers for
339 the YAZ frontend server. The configution is XML based and
340 support specificition of CQL to RPN mappings and explain information.
341 See section "Virtual Hosts" in the YAZ manual.
343 Extended OPAC display utility. OPAC display utility renders
344 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
345 to supplement yaz_marc_decode_wrbuf.
347 Fixed a bug in MARC decoder that could caused it to crash for some
348 invalid MARC records. More diagnostics and warnings where added in
349 XML output (warnings, etc are stored in comments).
351 --- 2.0.34 2005/02/08
353 Fixes for UNIX domain sockets. Bug #261.
355 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
357 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
358 Added yaz_marc_subfield_str which defines subfield lead string which is
359 used in YAZ_MARC_LINE format. Default string is blank+$. Added
360 yaz_marc_endline_str which defines end of fields string used in
361 YAZ_MARC_LINE format. Default string is newline.
363 Experimental support for MarcXChange. This format can be produced
364 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
365 http://www.bs.dk/standards/MarcXchange.xsd
367 Added yaz-client commands scansize that sets maximum number of
368 entries to be returned by scan.
370 --- 2.0.32 2005/01/11
372 Added support for SRW scan in yaz-client and Generic Frontend Server.
374 * Added whereInList member to SRW Scan Term.
376 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
378 Fixed NMEM system to return aligned blocks on the smallest boundaries
379 that are suitably aligned for all possible types on the particular
380 architecture YAZ is being built for.
382 --- 2.0.30 2005/01/04
384 Fixed numerious warnings that was issued with newer versions of GCC.
386 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
387 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
390 Make YAZ Generic Frontend Server slightly faster.
392 Enhance (and reduce) logging for Generic Frontend Server.
394 Revert YAZ log system so that it flushes every write operation
395 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
397 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
398 instead of LOG_, due to name clash with syslog(3). LOG_ are still
399 present. New applications should define YAZ_USE_NEW_LOG=1 - this
400 will effectively disable old definitions.
402 --- 2.0.28 2004/11/09
404 Added yaz_log_time_format which specifies log format using
407 Added yaz_log_module_level which returns mask for a module. Value
408 is non-zero mask a if module is enabled; zero if disabled.
410 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
411 in include/yaz/cql.h.
413 Fixed bug #176: Dont throw diagnostics on empty SRU args.
415 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
417 Fixed bug #172: RPM builds does not enable SSL.
419 Doxyfile.in part of dist. Doxyfile generated by configure.
421 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
422 are given and the corresponding component does not exist.
424 Extend CCL documentation in YAZ reference. Describe r=r.
426 --- 2.0.26 2004/10/01
428 Fixed MARC->MARCXML conversion to properly deal with
429 fields, subfields, indicators having non-ASCII characters.
431 Fixed MARC->MARCXML conversion so that ASCII control characters
432 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
435 Added YAZ GFS support for conversion from Z39.50 surrogate
436 diagnostics to SRW surrogate diagnostics.
438 Bug fix: YAZ GFS did not return schema in explainResponse.
440 --- 2.0.25 2004/09/30
442 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
443 now converts recordSchema to elementSetName as well as schema URI.
445 Fixed bug in COMSTACK that prevented HTTP request packages from being
448 --- 2.0.24 2004/09/29
450 Added CCL facility r=r "range" which is similar to r=o "ordered" but
451 does not require white-space before and after the dash in a range, e.g.
452 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
455 Fixed a few AC_TRY_LINK configure tests that did not operate properly
456 due to new GCC removing "redundant" code.
458 Added yaz-client commands scanpos and scanstep that sets preferred
459 position and step-size for scan.
461 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
463 Added CCL utility ccl_qual_buf which parses one or more CCL
464 spec lines in a buffer.
466 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
467 of name and value - ignoring empty lines and comments.
469 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
471 Added odr_get_element_path which returns current element path for an
472 ODR handle. This utility is useful in error handling or user-defined
475 Added ODR_PRINT utility odr_set_stream which is is a more generic
476 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
477 to a write function and pointer to close function. The close function - if
478 non-NULL - will be called during odr_destroy.
480 Fixed bug in CCL parser where truncation char was not removed from
481 right side when truncation=both was in effect.
483 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
486 --- 2.0.23 2004/08/11
488 Fix buffer overrun in CQL parser when dealing with proximity (%).
490 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
491 to UTF-8/UCS conversion is now only based on codetables.xml.
493 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
495 --- 2.0.22 2004/08/06
497 Add support for more "commit changes" in ZOOM (uses Extended Services).
499 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
502 Yet another small fix for configure of SSL.
504 --- 2.0.21 2004/05/14
506 Fix SSL libs for configure when --with-openssl=DIR is given.
508 --- 2.0.20 2004/05/10
510 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
512 SSL comstack now uses yaz.pem certificate file on server side
513 by default. Certificate filename can be configured by calling
514 comstack function cs_set_ssl_certificate_file before cs_bind is used.
516 Fix bug regarding multiple calls to ZOOM_connection_connect.
518 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
520 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
521 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
523 ZOOM now allows inspection of X509 peer certificate for verification.
524 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
526 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
527 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
528 as "modular" but it simplifies things.
530 Added cs_get_peer_certificate to that returns peer X509 PEM.
532 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
533 NULL if SSL is unavailable.
535 Documentation about MARC decoding tools.
537 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
539 --- 2.0.19 2004/03/30
541 Rename CHANGELOG to NEWS to follow GNU style packing.
543 Fix bug with missing initialization of member in init_diagnostics.
544 This bug affects threaded version of GFS server.
546 --- 2.0.18 2004/03/20
548 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
551 Ensure zlib.dll is packed with Windows install.
553 --- 2.0.17 2004/03/17
555 Fix encoding of xsd:string to use text instead of CDATA.
557 Fix endless loop in CQL parser with unbalanced ".
559 Use a more compact way to store MARC-8 conversion tables.
561 --- 2.0.16 2004/03/16 Debian only
563 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
566 Update CQL parser to use new CQL 1.1 modifiers for booleans and
571 --- 2.0.15 2004/03/01
573 Another fix for decoding of XML packed records.
575 --- 2.0.14 2004/02/25
577 Fixes for Chunked encoding. White space not ignored after length spec.
579 Update NS and use default NS for SRW diagnostic elements.
581 --- 2.0.13 2004/02/23
583 Implement ZOOM_resultset_cache_reset which resets record cache.
585 Implement ZOOM_resultset_sort which sorts a result set.
587 Implement chunked HTTP transfer.
589 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
591 --- 2.0.12 2004/02/16
593 Added member 'schema' to bend_explain_rr structure so that backend
594 can specify explain record identifier. Defaults to Zeerex 2.0.
596 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
598 --- 2.0.11 2004/02/16
600 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
603 Added init command for yaz-client which sends "extra" init request.
605 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
606 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
608 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
610 Make ZOOM error code for "invalid query".
612 Fixed compilation for SSL which wasn't properly enabled for all platforms.
614 --- 2.0.10 2004/02/05
616 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
619 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
621 Added option -p <file> to make Generic Frontend Server to write PID file.
623 Added option -D to put Generic Frontend Server in background on its own.
625 Make ZOOM C recognize option "password". If unset, "pass" is used
626 (for backwards compatibility).
628 Fixed a bug in Generic Frontend Server that could make it crash if a
629 client sets characterSetNegotation bit, but didn't pass negotiation stuff
632 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
633 Must be issued before open, in order to be in effect.
635 --- 2.0.9-6 2004/01/12 Debian/Windows
637 Make the SRU server more picky WRT unknown params, etc.
639 Bug fix: ZOOM scan response didn't return displayTerm - when present.
641 New YAZ client command, options, that sets Z39.50 options.
643 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
644 options from a string of tokens (one token for each option bit).
646 Update SRW diagnostic code messages.
648 --- 2.0.9-5 2004/01/07 Debian/Windows
650 Handle user defined stylesheet for SRW/SRU.
652 --- 2.0.9-4 2004/01/06 Debian/Windows
654 Fix bug in decoding of Content-Length.
656 --- 2.0.9-3 2004/01/06 Debian/Windows
658 Fix a bug with decoding of XML packed records.
660 --- 2.0.9-2 2004/01/05 Debian only
662 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
664 Fix bug in SRW/SRU diagnostics decoding.
668 Fixed bug in Generic Frontend Server which could drop records exceeding
669 preferred message size. Reported and fixed by Irina Dijour.
671 Fixed calculation of package size for structured records in Generic
672 Frontend Server. Reported and fixed by Irina Dijour.
674 Fixed namespace for SRW/SRU diagnostics.
676 Fixed SEGV in yaz-client that occured for HTTP connection errors.
680 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
681 this version is incompatible with version 1.0 and older YAZ SRW/SRU
684 CQL changes to reflect recent changes to the specification:
685 * Documentation talks about context sets instead of index sets.
686 * Documentation talks about indexes instead of qualifiers.
687 * The CQL-to-PQF transformer's configuration file now uses
688 "index.set.name = <attributes>" instead of the old form
689 "qualifier.set.name = <attributes>". (Both forms are still
690 understood but the latter is deprecated.)
691 * CQL terms with no explicit index specified are now interpreted as
692 cql.serverChoice instead of srw.serverChoice (which of course
693 behaves exactly the same.)
697 MARC conversion can now generate ISO2709 output in another
698 character set. yaz-marcdump uses this facility if you invoke it
701 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
702 functions from there can be used from C++.
706 Frontend server now transfers memory from decoded packages to stream
709 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
710 references to show up.
712 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
713 the ZOOM Abstract API. The older names for the same options are still
714 also supported for the benefit of old applications.
716 ZOOM-C supports "implementationId" and "implementationVersion" options
717 to go along with "implementationName". These allow the user code to
718 specify identification strings to be sent to servers.
719 Add OID for the new ExtLite attribute set.
721 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
722 as requested/supplid by Ere Maijala <ere@atp.fi>
724 For generic frontend server, reverse the order of
725 "toolkit-supplied / application-supplied" strings sent as implementationId,
726 Name and Version. Also, remove the spaces around the slash. This brings
727 the GFS in line with the behaviour of ZOOM-C on the client side.
729 Add function ZOOM_scanset_display_term.
731 yaz-client shows scan displayTerm if present.
733 Utility yaz-iconv is now installed by default along with the man page
736 Extend configure check for OpenSSL to use pkg-config where available (such
739 Incorporate patch by Morten Bogeskov which allows a Unix file socket
740 server to specify uid/gid/mask for socket using the format
741 unix:[user=uid,][group=gid,][umask=mask,]file=path
742 If file= is omitted the existing format is assumed, e.g.
744 in which case the mask is 0666 (rw for everybody).
746 Major restructure of YAZ source. All source in libyaz is in src directory.
747 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
748 util (utility programs such as ASN.1 compiler, yaz-marcdump).
750 Added man page for utility yaz-marcdump (used to be called marcdump).
751 yaz-marcdump is installed by 'make install'.
753 Fixed a memory leak in Generic Frontend Server that occurred when decoding
754 of incoming package failed.
756 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
758 Change prototype of odr_perror: add const to message string.
760 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
762 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
763 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
764 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
765 DNS lookup. There should not be any compatibility problems with this
766 assuming that blocking=1 or 0 is used.
768 Fix bad reference in UNIX comstack in function cs_addrstr.
770 Fix for compilation on AIX.
772 The generic front-end server (server/seshigh.c) now supports returning
773 Init diagnostics to the client in User-information-field, in
774 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
779 Allow any CQL relation (not just all,any,exact,scr).
781 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
782 that features the same UI.
784 Implemented command update0 in YAZ client which is equivalent to
785 update but uses old of Ext Update ASN.1.
787 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
788 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
789 Previously no OID was used for this info.
791 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
792 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
793 returns 'malformed search term' otherwise.
795 SortResponse member resultCount now set to NULL in sort handler of
798 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
801 Add three new utility functions for translating OIDs between various
802 formats -- symbolic name such as "Usmarc", minus-1-terminated int
803 arrays and dotted strings such as "1.2.840.10003.9.5.1":
804 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
805 char *oid_to_dotstring(const int *oid, char *oidbuf);
806 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
808 Reverted modifications for ES Update definition for z_IU0Update
809 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
810 is back to YAZ 2.0.2.
812 String value attributes for CCL parser.
814 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
815 which their FirstSearch server returns in Init responses, sometimes
816 carrying useful diagnostic information when Init fails. This has the
817 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
818 "z39.50/oclcui.asn", where its definition is somewhat different from
819 what OCLC document on their web-site, as required to interoperate with
822 Support for anonymous authentication in yaz-client. Use the command
825 * Fix the OID of the Index Data-local "admin" Extended Service from
826 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
827 the 1000, which indicates a locally-defined OID, was a mistake.
831 Fix CCL directive @case handling so that it affects string match for
832 both CCL keywords and qualifiers.
834 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
835 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
836 Decoder has been updated with ASN.1 changes as listed in
837 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
838 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
839 z_IUUpdate, remains unchanged.
841 ZOOM_record_get may now return a record in a specific character set.
842 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
843 "from" is the character set of record as returned by target. "to" is
844 the character set to be returned. If omitted, "to" is UTF-8.
846 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
848 New ODR utility, odr_getelement, which returns name of element for
849 which encoding/decoding failed.
851 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
852 in cases where a required element was omitted.
854 Bug fix: some MARC8 sequences were not converted.
856 New ZOOM option "step" which specifies number of records to be
857 retrieved in one chunk. Used in conjunction with "start" and "count".
859 SRW support for yaz-client. Use scheme http: to use it, e.g.
862 yaz-client no longer does (un)intelligent character set conversions
863 by default. Can be enabled with charset and marc_charset commands.
865 xmalloc trace fix for 64-bit systems such as DEC alpha.
867 Solaris 2.6 compile fix.
869 New function, cql_strerror() translates SRW error codes, as returned
870 by cql_transform_error(), into human-readable English strings. Used
871 in yaz-client diagnostics when appropriate.
873 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
874 converts it into a type-1 query which is sent to the server. This
875 makes CQL available for use with all Z-servers, as opposed to the tiny
876 minority that can handle CQL queries themselves.
880 New Debian package layout similar to the Redhat Package layout.
882 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
883 and search result respectively.
887 Redhat package is now several packages: libyaz (runtime libraries),
888 libyaz-devel (development and documentation, and yaz (utility programs).
889 Package spec file by Morten Bøgeskov.
891 New member 'schema' in struct bend_fetch_rr which the name of requested
892 schema (SRW/SRU) for record (or NULL if none was given). The fetch
893 handler MAY set this to reflect the schema of the returned record.
895 New member 'display_term' in struct scan_entry. GFS now sets member entries
896 and allocates scan entries to be filled by user scan handler. In previous
897 version, entries member was allocated by the scan handler. That still works,
898 but the GFS will ignore member display_term - assuming it was NOT set by
899 the handler. The fact that the GFS now allocates the entries both allows
900 for new members and makes a scan handler easier to write.
902 Fix CQL lex buffer overflow.
904 SRW/SRU recordPacking. For SRW default recordPacking is string. For
905 SRU default recordPacking is string.
907 SRU protocol support for frontend server.
909 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
911 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
913 Added scan for the ZOOM shell (zoomsh).
917 * String Identifers for Schemas (Amendment 5).
918 http://lcweb.loc.gov/z3950/agency/amend/am5.html
919 Old definition for schema
920 Odr_oid *schema; /* OPT */
925 Z_InternationalString *uri;
926 #define Z_Schema_oid 1
927 #define Z_Schema_uri 2
930 * resultCount parameter to Sort Response (Amendment 1).
931 http://lcweb.loc.gov/z3950/agency/amend/am1.html
933 Support for SRW 1.0 over HTTP. This is an optional feature and
934 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
937 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
938 on the same port. SRW SearchRetrieveRequests are mapped
939 to bend_init,bend_search,bend_fetch,bend_close.
941 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
943 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
944 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
946 ZOOM connections are SRW based if schem http is used for hostname
947 in connect, e.g. z = ZOOM_connection_new("http://myserver");
948 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
950 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
951 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
952 distance=n, order=true/false, relation=le, prox unit=word. If
953 n is omitted, distance 1 is used.
955 Fixed problem with C compiler include path in wrong order.
957 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
958 on Solaris. Patch from Ko van der Sloot.
960 New MARC decode API. All new functions operate on a yaz_marc_t
961 handle. The most important new functions are: yaz_marc_create,
962 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
963 decode and destroy respectively. Decoder can produce formats
964 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
965 include/yaz/marcdisp.h.
967 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
968 to UTF-8, UCS-32, wchar_t or Latin-1.
970 * Prototypes for yaz_iconv_-functions moved to separate header
971 include/yaz/yaz-iconv.h.
973 Make a few private functions 'static' in unix.c. This prevents
974 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
976 For ZOOM connection, the options targetImplementation{Id,Name,Version}
977 are set when Init Response is received.
979 New function ZOOM_connection_error_x similar to ZOOM_connection_error
980 but returns diagnostic set as well.
982 New function yaz_strerror which is a portable wrapper for
983 strerror/strerror_r/GetLastMessage.
985 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
986 is returned for MARC. If type is "oai", then OAI MARC is returned.
988 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
993 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
995 Fix bad race conditions on SIGTERM and terminate gracefully in
998 Move retrieval (data1) module to Zebra since nobody seems to be
1001 Add GRS-1 render for ZOOM using same format as yaz-client.
1003 --- 1.9.1 2002/10/05
1005 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1007 Fix broken ESpec handling in data1 module.
1009 SGML reader parses comments and makes them part of the data1 tree.
1011 Added several type casts so that YAZ compiles as C++ code.
1013 ZOOM didn't handle PDU encoding failures properly.
1015 Added more Bib-1 diagnostics (approved extensions).
1017 GNU configure: better check for iconv.
1019 More portable use of accept, getpeername. Check for socklen_t. Use
1020 int/size_t if socklen_t is not defined.
1024 PQF parser rejects bad queries - including those with extra
1025 characters in them. PQF parser used to silently ignore that.
1026 Cleaner API for PQF added, which allows you to get detailed
1027 error information for bad queries (see yaz/pquery.h).
1029 Fixed bug in ZOOM_record_get for type "database".
1031 Implemented mini iconv library supporting conversions between
1032 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1034 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1036 --- 1.8.9 2002/08/20
1038 Fixed ZOOM C record cache so that preferredRecordSyntax and
1039 elementSetName is used to check for already fetched records.
1041 --- 1.8.8 2002/08/02
1043 Added three members in bend_initrequest structure to facilitate
1044 character set negotiation.
1046 Fixed a bug in frontend server that could cause indefinite
1047 loops under rare conditions.
1049 Revised character set utilities (charneg.h) so that encoding
1050 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1052 For PQF, directive @term <type> sets term type for Scan/Search.
1053 Here <type> is general, string, numeric, null. The term type
1054 is inherited - just like @attr.
1056 New call odr_set_charset that sets character set conversion for
1057 international-strings on a ODR stream. Prototype is:
1058 int odr_set_charset(ODR o, const char *to, const char *from);
1059 The InternationalString is still represented as C string in YAZ
1060 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1061 won't). On the protocol level, you can use any encoding.
1063 Support for UNIX sockets in ZOOM.
1065 Solaris recv sometimes returns errno == ENOENT. It is treated as
1066 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1068 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1069 both client and server. Code by Morten Bøgeskov.
1071 --- 1.8.7 2002/05/22
1073 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1074 that they can be used directly from Visual Basic. You must recompile
1075 your windows APP if you're using ZOOM.
1077 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1078 Commands "lang" and "charset" sets language and character set respectively.
1079 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1080 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1082 Attributes from multiple CCL fields may be OR'ed rather than merged
1083 using directive "@field or". Fields are still merged by default -
1084 equivalent to "@field merge".
1086 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1089 Fixed bug in zget for parameter ExtendedServicesResponse.
1093 --- 1.8.6 2002/03/25
1095 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1097 Client displays USR.1:SearchResult-1 (hits per term).
1099 Additional Search Info for search in Generic Frontend Server.
1101 Fixed CCL parsing of "field=s".
1103 WIN32 installer - using the excellent NSIS software from nullsoft.
1105 Fixed CCL parsing of "field = - <number>".
1107 Added function yaz_marc_decode that decodes MARC for line mode
1108 display or XML (similar to that used by JZKit).
1110 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1111 Z39.50. But ISO/ILL was, however.
1113 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1114 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1116 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1117 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1119 --- 1.8.5 2002/02/03
1121 New YAZ client features: Command completion and new commands:
1122 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1123 Code provided by Jacob Poulsen.
1125 New call oid_trav, that visits all registered OIDs via callback.
1127 Function ZOOM_record_get now returns const char pointer rather than
1128 void pointer. It saves a lot of type casts.
1130 For YAZ client, command "auth" now allows you to set authentication
1131 in IdPass style. It is enabled when three tokens are given - order
1132 is user, group and password.
1134 Fix memory leaks in MARC record handling for ZOOM.
1136 New option for YAZ client, -k <kilobytes> that sets
1137 maximum record size. Similar to -k option for generic frontend
1138 server and yaz-ztest.
1140 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1142 Prefix query parser reports "fail" when bad attribute set is given.
1144 Fix in MARC decoder. Proximity logging. Fix for attribute set
1145 in scan handler for server. Patches by Shigeru Ishida.
1147 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1150 Configure option --with-openssl=<dir> now works when a directory is
1151 specified. Patch provided by Morten Bøgeskov.
1153 New option for YAZ client, -u <auth>, that sets authentication.
1155 ZOOM fix: error information was sometimes "missing", since error
1156 was cleared/reset too when it shouldn't.
1158 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1160 --- 1.8.4 2002/01/04
1162 Scan for ZOOM API. New object ZOOM_scanset. New functions
1163 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1164 ZOOM_scanset_destroy.
1166 New ZOOM function, ZOOM_connection_last_event, that returns type
1167 of last event (such as "receive data", "send data", "apdu received",
1170 New ZOOM option, schema, that specifies schema for retrieval.
1172 New CCL feature. Qualifiers can be aliases for one or more
1173 other qualifiers (if more than one is given, OR is used).
1175 ZOOM uses named result sets if target supports it.
1177 Two new YAZ client commands: . (dot, which sources a script of YAZ
1178 client commands), and ! (to execute shell command.). Implemented
1181 Working on Debian packages.
1183 --- 1.8.3 2001/11/19
1185 YAZ client enables named result sets only if target supports it.
1187 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1189 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1190 with key="host" to get same result.
1192 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1193 Function Z3950_resultset_record(s) returns references to records
1194 "owned" by resultset. To become owner use Z3950_record_clone.
1196 Function z_ext_record handles Extended Services. Thanks to
1199 --- 1.8.2 2001/11/12
1201 CCL Parser fix: ignore token comma when dealing with and-lists.
1203 Documentation updates for COMSTACK.
1205 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1206 Changed prototype Z3950_records. For some functions, int parameters
1207 were changed to size_t.
1209 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1212 New MARC decode/display function, marc_display_exl, which properly rejects
1213 non-ISO2709 records. YAZ client uses it.
1215 --- 1.8.1 2001/10/29
1217 Fix bug: local attribute set wasn't set correctly in PQF strings.
1221 * Old Z39.50 codecs no longer supported.
1223 Added ZOOM C binding. See http://zoom.z3950.org/
1225 Renamed states for COMSTACKs to avoid confusion with events.
1227 Implemented cs_look and proper cs_rcvconnect.
1229 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1231 Configure detects POSIX threads on OpenBSD.
1233 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1234 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1236 When error is returned from present handler, non-surrogate diagnostic
1237 is returned in present response (and fetch handler is no longer called).
1239 * Minor adjustments to pquery parser (PQF). Token characters may be
1240 escaped by using backslash (C-style).
1242 PQF parser allows string attribute values to be specified. For @attr,
1243 non-numeric characters after the equal-sign are treated as strings
1244 (e.g. @attr 9=title).
1246 CCL trunction character may be defined (@truncation in file)
1248 * function zget_ExtendedServicesRequest sets waitAction to
1249 waitIfPossible (was wait).
1251 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1254 CCL operator names may be set in field definition files (CCL_bibset).
1255 See ccl/bib1 for an example.
1257 Fixes in ASN.1 compiler for C++ compatibility.
1259 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1260 and "op_or" to avoid conflict with C++.
1262 Fixed problem with GNU readline detection on Redhat 7.0.
1264 Added step-size for Scan backend handler.
1266 Fixed bug that made the frontend server crash when no attribute
1267 set was specified for scan.
1269 Front-end server automatically switches to original working directory
1270 when installed as an NT service. Previously -w had to be specified to
1273 Added extended attributes for retrieval module (data1), so that data1
1274 records carry d1_readXML/SGML attributes. d1_read also supports
1275 null-data rules ( <tag/>)
1277 On UNIX when POSIX threads are available, a separate library libyazthread
1278 is created. Programmers should link with that library and the yaz library
1279 when using threads. The reason for the split was that some applications
1280 on Linux, such as Apache, doesn't work well when using shared objects that
1283 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1284 (or any frontend server) in SSL mode by specifying ssl: followed by
1285 address. Only tested on UNIX.
1287 Added feature for CCL module. Virtual structure s=al or s=ol generates
1288 and-list and or-list respectively instead of phrase search.
1292 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1293 log_mask_str. This was done to avoid name conflicts with other libraries
1294 (such as other PHP extensions).
1296 Added raw OID member for preferred record syntax (request_format_raw)
1297 and returned record syntax (output_format_raw) for backend fetch method.
1299 Config file yaz-config now accepts options so that it returns specific
1300 compile settings, etc. Thanks to Morten Bøgeskov <morten@bogeskov.dk>
1302 Shared library support for UNIX using GNU libtool.
1304 * Modified backend interface. Request/Response struct's replaced by
1305 one read/write C struct. For example bend_fetchrequest and
1306 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1307 Every handler - even search has to be registered in bend_init
1308 handler. This means that the YAZ library no longer refers to
1309 external functions and it makes it possible to make the whole
1310 thing a single DLL/SO.
1312 Added Segment handler for backend server.
1314 Added Zmbol/Zebra administrative functions to YAZ client.
1316 Threaded frontend server on UNIX (when POSIX Threads are available).
1317 Starting the server with option -T enables multi-threading.
1321 Added configure option --enable-comp/disable-comp to control use
1322 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1323 located in sub directory asn.
1325 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1326 in ${exec_prefix}/bin along with the other programs yaz-client and
1329 GNU automake used to maintain makefiles.
1331 Added several OID's.
1333 Changed retrieval module so that we can load records with no abstract
1334 syntax defined. Tagpaths in these records are fully composed of string
1337 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1341 On UNIX, the generated makefile now supports a proper 'make install'.
1342 The prefix can be set via GNU configure to set the install location
1343 (default is /usr/local).
1345 * YAZ programs client and ztest were renamed to yaz-client and
1346 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1347 locations, such as /usr/bin,/usr/local/bin,etc.
1349 * YAZ Header files were moved from include to include/yaz. YAZ Header
1350 files are referred to as include <yaz/log.h> rather than <log.h>.
1351 The YAZ include path (-I ..) is therefore the same as before. Programmers
1352 should update their #include statements or use -Ipath/include/yaz
1353 instead. The main motivation for doing this change is that YAZ header files
1354 can be installed in "standard" locations /usr/include,/usr/local/include
1355 without introducing conflicts, since ALL YAZ header files are stored
1356 in subdirectory yaz (under /usr/include for example).
1358 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
1359 rather than project/workspace files. We switched because project files
1360 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
1363 Changed name of logging function, logf, to yaz_log, to prevent name
1364 clash with some math-log functions. The YAZ header log.h defines logf
1365 to yaz_log (#define) so there should be no incompatibilities by this
1368 Added bend_start/bend_stop handlers for server. These handler are
1369 called on start/stop of server. For windows they are called whenever
1370 a service is started/stopped.
1372 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
1373 a fairly small ASN.1 compiler written in Tcl. The compiler is located
1374 in util/yc.tcl. The auto-generated C code structures are, in a few
1375 cases, incompatible with the old decoders. There are differences in the
1376 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
1377 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
1378 The preprocessor variable ASN_COMPILED is defined when the compiled
1379 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
1380 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
1381 wish to use the old encoders/decoders you can specify --disable-yc
1384 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
1385 version so that it supports both new - and old version of DB Update
1387 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
1388 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
1389 change. The name parameter can be set to 0 in which no name is specified
1390 for the construction. The macros odr_implicit and odr_explicit sets name
1391 parameter to zero for the construction involved. New macros
1392 odr_implicit_tag and odr_explicit_tag are similar to the others,
1393 except that a name parameter is added. For programmers' that don't use
1394 ODR they probably only need to change the call to z_APDU and z_External.
1396 Added access control facility by interfacing the TCP wrapper library.
1397 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
1398 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
1399 name of the daemon and enables the access control as specified in
1400 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
1402 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
1403 den Dool <H.M.vdnDool@kub.nl>.
1405 Added reference ID parameter to most functions in server API - refer
1406 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
1408 Changed name of ccl library to libccl.a (was ccl.a).
1410 Fixed bug in decoder for Explain (Category TargetInfo).
1412 Added support for GNU readline in client. Thanks to Jacob Poulsen
1413 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
1415 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
1416 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
1417 IMPLEMENTATION! This change was made to the development version before
1418 the ZIG decided to retract the amendment. If any users MUST be
1419 compatible with the original Update definition, PLEASE CONTACT US, and
1420 we will include a separate definition corresponding to the old Update
1421 ES. Note that because of the change to the ASN.1 of the
1422 TaskPackageRecordStructure we cannot define a single structure that
1423 will support both versions.
1425 * Added const modifier to buffer parameter for some ODR/BER encoding
1426 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
1427 completeWAIS, odr_dumpBER.
1429 Fixed bug in client.c which caused a crash when a scanResponse didn't
1430 contain positionOfTerm.
1432 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
1433 * will cause an error in a client if a non-YAZ target sends both a
1434 * list of Scan entries and non-surrogate diagnostics.
1436 Retrieval module enhancements. Tag sets may be typed in the reference
1437 to it. From the .abs-file the "tagset" directive takes a third optional
1438 integer type for the tag set referenced. From a .tag-file the "include"
1439 directive takes a third optional type as well. The old "type" directive
1440 in the tag set itself is still recognized but acts as the default type
1443 Backend interface change. Individual Scan terms returned from bend_scan
1444 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
1445 in include/backend.h.
1447 Retrieval module enhancements. Multiple tag sets and attribute sets may
1448 be specified in abstract syntax specs. Revised the error/warning for
1449 logging messages reported by the retrieval module when reading the
1452 Object Identifier system (oid_..) changed. The API is backwards
1453 compatible but the oid-routines now allocates new OID's when needed.
1454 Raw OID's may be specified in oid_getvalbyname.
1456 YAZ now uses GNU configure to generate Makefile(s).
1458 * Minor changes in some of the member names of DeleteResultSetRequest and
1459 DeleteResultSetResponse. See include/proto.h.
1461 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
1462 and added member 'languages' in TargetInfo (which was missing).
1464 Changed the way attribute sets are handled in the retrieval
1465 module. These are now cached, just like the abstract syntaxes
1468 Changed YAZ so that it links with compiled ASN.1.
1470 Added Explain-schema definitions and mapping routines. The following
1471 Explain categories have been implemented: AttributeDetails,
1472 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
1474 Fixed minor bug in Windows version of Server Library.
1476 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
1478 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
1480 Added EXTERNAL: UNIverse Resource Report (non-standard).
1482 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
1483 ENUMERATED and SET OF.
1485 * Added 'const' to some of the char pointer arguments for the
1486 functions, data1_read_node, data1_getelementbytagname,
1487 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
1490 Fixed bug in data1_insert_taggeddata - the last_child member of
1491 parent wasn't initialised.
1493 * Changed data1_read_record and data1_read_node so that the supplied
1494 "SGML"-buffer is read-only. In particular the resulting data1 - tree
1495 doesn't refer to any parts of the "SGML"-buffer.
1497 Fixed bug in server library (Windows version of statserv_remove).
1499 * Changed code so that it compiles as C++. The type definition
1500 of Odr_fun which is a member of Odr_arm was changed. The result is,
1501 that an explicit typecast is needed for the fun pointer when
1502 using Odr_arm - as in:
1503 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
1505 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
1507 Implemented the new structured date and time definition as approved
1508 by the ZIG. Added schemaId element to the specificTag in Espec-1
1509 (also approved at the last ZIG). Thanks to RVDM.
1511 Added some Object identifiers (RVDM).
1513 Changed the Update Extended Service (RVDM).
1515 Added command "refid" to client which specifies referenceId for
1516 the following requests.
1518 Implemented extended service handling for server. See ztest.c
1519 for an example as well as backend.h. New handlers are registerd
1520 in the Init handler.
1522 * Changed interface for sort in server.
1524 Added new members to statserv_options_block. It allows a server
1525 to read options from another source than just the command line. Thanks
1526 to Charles Woodfield.
1528 * Changed definition of Z_Triple in file prt-grs.h - member boolean
1529 renamed to zboolean. Some C++ compilers complained about the name.
1531 Minor changes to gils.abs. Added index 's' (sort) on title
1532 and date/time-last-modified.
1534 --- 1.4pl2 1998/1/30
1536 Fixed bug in server library regarding inetd mode (-i). This bug
1537 was introduced by release 1.4.
1539 --- 1.4pl1 1998/1/29
1541 Added sort facility in client and backend server interface.
1543 Fixed problem with dependencies in Makefile(s).
1545 Fixed bugs for encoders/decoders of extended services and
1548 Implemented sub-tree feature for schemas. Sub-trees are
1549 referenced in *.abs-files. See explain.abs for an example
1550 of the use of this feature.
1552 Modified bib1.att; local attributes for ANY didn't include
1553 ANY itself (only affects use of the retrieval module).
1555 Fixed bug in plain SGML reader in function data1_read_node:
1556 tags with prefix "var" was incorrectly interpreted as variants.
1558 Added feature "sub-schemas" to enable references to - and definitions
1559 of - group of elements.
1561 * Removed member parent from type data1_element (in data1.h).
1563 Implemented function odr_nullval() that returns the value of
1566 * Removed member num_children from data1_node (in data1.h).
1568 Made NT service interface part of the server library. The
1569 function statserv_main uses the NT service when required and
1570 calls the statserv_start / statserv_close routines.
1572 Routine zget_SearchRequest and zget_PresentRequest fills
1573 resultSetName/Id member with "default" instead of "Default".
1575 Fixed memory leak in server. Request queue member wasn't freed.
1577 Fixed nmem_exit so that memory is freed.
1581 Revised the CCL parser utility to be thread safe.
1583 Added function, oid_ent_to_oid, to replace the function
1584 oid_getoidbyent, which is not thread safe.
1586 * Added nmem_init and nmem_exit to initialize and release
1587 NMEM resources. Function nmem_init should be called once in the
1588 initial thread before NMEM/ODR is used. statserv.c and client.c
1589 have been changed accordingly. The change was necessary to make
1590 NMEM thread safe. The NMEM memory pool is shared amongst threads
1591 in a process. Unix-based applications will still work fine without
1594 Added NT Services interface for the the Z39.50 (statserv) Server.
1595 Refer to the ztest.c source on the usage.
1597 Windows 95/NT port using MSVC5.0. Project files are included in the
1600 * Defined new 'global' handle for the retrieval (data1) system. The
1601 new handled, data1_handle, describes the state of the data1 system.
1602 This handle is passed as first argument to virtually all
1603 data1 related routines. The functions data1_create and data1_destroy
1604 creates and destroys a data1 handle respectively.
1606 Added ODR encode stream member to all backend request structures
1607 init, search, scan etc. This stream should be used to allocate all
1608 memory used for the response when thread safe operation is needed.
1610 Changed the comstack utility, cs_addstr, to be thread safe. The
1611 returned hostname string returned by the function is now part the
1614 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
1615 function. The cs_straddr takes a COMSTACK handle as argument, so this
1616 function must be used after cs_create and before bind/connect.
1617 This function is thread safe.
1619 Moved test server to 'ztest' directory - generic server code still
1620 in 'server' directory.
1622 Made prefix query (pquery.c) utility thread safe.
1624 Added new function modifier YAZ_EXPORT to 'export' public DLL
1625 functions when using windows (see include/yconfig.h).
1627 Added definitions to the OID database (util/oid.c) (RVDM).
1629 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
1631 Added call to ccl_rpn_delete in client program.
1633 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
1634 release of RPN structure.
1636 Added support for C++, headers uses extern "C" for public definitions.
1637 With input from RVDM.
1639 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
1640 Thanks to Ronald van der Meer (RVDM).
1642 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
1644 Added support for private extensions to the OID database
1645 (oid_setprivateoids()). Thanks to RVDM.
1647 Added optional, physical ANY (key replication)
1649 Fixed null-reference problem in GRS-1 output filter.
1651 Proximity operator added to Prefix Query Format (PQF).
1653 In test client command "base" accepts multiple databases.
1655 Fixed bug in cs_close stack that caused trouble with WINSOCK.
1659 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1661 Smallish bug-fixes in the new encoders/decoders (explain).
1663 Bug fixed in DeleteRequest.
1665 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
1667 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
1669 Added SOIF syntax (using private OID for now) to retrieval module and client.
1671 Added Update extended service.
1673 Added SearchResult-1 additional info structure.
1675 Added optional CCL (ISO8777) interpreter as separate module. Available
1678 --- 1.2 1996/6/10 (1st anniversary release)
1680 Added Summary record syntax. Lightly tested.
1682 Added OPAC record syntax. Untested.
1684 Added ResourceReport service encoders/decoders. Untested.
1686 Fixed bug in z_Unit - wrong tagging on unitSystem.
1688 Fixed bug in the DiagRecs decoder.
1690 Added options for max PDU size and session timeout to frontend-server.
1692 Added documentation of query-language parsers and other supporting utilities.
1694 [frontend-server] Added Attribute set to the bend_scanrequest API.
1696 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
1697 surrogate diagnostics were generated.
1699 [retrieval] Allow multiple local values for attribute.
1701 [retrieval] Allow multiple attributes per element in .abs files. index type.
1703 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
1705 --- 1.1pl2 1996/4/10
1707 Minor changes, mostly specific to Zebra's requirements (retrieval)
1711 Repaired bug in frontend server when running multiple listening
1712 endpoints in dynamic mode.
1714 z_External() now won't break if a known, ASN.1 value comes encapsulated
1715 in an octet-string. The value will pass through unmodified in an Odr_oct.
1717 Added a bit of code to the demo client to decode & display
1718 ASN.1-structured records represented in the octet-aligned branch of
1719 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
1721 Added z_ext_getentbyref() to the ASN module. Doc updated.
1723 * Completed the SCAN definition in the ASN module. This may break SCAN
1724 code based on older YAZ-versions at compile-time. The fix is easy -
1727 * Added 'displayTerm' and OtherInformation to the TermInfo structure
1728 under the SCAN definition. Remember to initialize this, server-people.
1730 Comstack should now support the WAIS protocol in TCP/IP mode. Note
1731 that this does not extend to ODR and ASN.
1733 Comstack allows insertion of established socket (primarily for
1734 inetd-operation of servers). Doc updated.
1736 Front-end server can now start from the inetd in TCP mode. Doc
1739 --- 1.0pl4 1996/1/24
1743 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
1744 the rank and record number.
1746 Adjustments to the frontend server.
1748 Fixed diagnostic BER dumper. It ignored the file argument.
1752 Various changes to retrieval module.
1754 Changed the union discriminators of the protocol files from enums to
1755 ints paired with #defines.
1757 *Changed oident.class to oident.oclass to avoid a reserved word in C++
1760 *Changed operator in the RPN structure to 'roperator', again to avoid a
1763 Fixed problems in Explain decoders/encoders.
1765 --- 1.0pl2 1995/12/6
1767 Memory bug in log module fixed.
1769 --- 1.0pl1 1995/12/5
1771 Occasional malloc() of 0 bytes fixed in d1_espec.c.
1773 Bug in Explain DatabaseInfo module fixed.
1775 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
1779 The shift to v1.0 signals that we now consider the *core* functionality
1780 of YAZ reasonably stable (the core being more or less equivalent to
1781 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
1782 tested (Explain not at all - though that will happen soonish).
1784 Minor changes to code to support Windows port.
1786 Various minor changes after we're getting to use GRS-1 & co. more.
1788 Added Espec-1 format.
1790 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
1791 of the protocol and it cannot be selected when encoding (maps into 'string'
1792 when decoding). Needed to talk to some servers.
1794 Demo client can request simple element set names.
1796 Added Diagnostic Format encoders/decoders.
1798 Added simple Close handling to frontend server (no hooks for resource
1799 reporting yet), and demonstration client.
1801 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
1803 --- 1.0b3 1995/08/24
1805 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
1806 handled incorrectly when records were requested in the searchResponse. This
1807 will only affect you if you use the frontend-server.
1809 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
1810 Test-client will ask for and print GRS1. Ztest will return dummy records
1813 Added Explain encoders/decoders to the service-level API. Untested.
1815 Added Extended Services: Item Order encoders and decoders to the Service-
1816 level API. Untested. We could use a recent copy of the pertinent bits
1817 of the ILL protocol to add those bits.
1819 Added diagnostic format 1 encoders/decoders to the service-level API.
1822 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
1823 odr_cons.c, which causes a more correct output.
1825 Fixed handling of searchRequest in frontend server. NextResultSetPosition
1826 was always set to 0 when no records were requested in the searchRequest.
1828 * Added better external-handling. This shouldn't harm old code that
1829 *encodes* externals. It can break code that looks for a
1830 'single-ASN1-type' representation, since those types that are known
1831 are now decoded immediately. Look at the SUTRS sample code in
1832 seshigh.c and client.c. Documentation updated.
1834 Handling of structured records in bend_fetchresponse. Length -1 marks
1835 structured record, type is deduced from format field.
1837 --- 1.0b2 1995/06/27
1838 Fairly quick maintenance release to add SUTRS support.
1840 Fixed handling of SUTRS records in the demonstration client.
1842 * Added format field to the bend_fetchrequest and bend_fetchresponce
1843 structures of the backend API (frontend server). When the record is
1844 returned, the value of the format field is mapped to an OID. The
1845 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
1846 of the record. The special value VAL_NONE in the bend_request means
1847 that no specific format was requested by the client. Documentation
1848 updated accordingly. Test server (ztest) will return a fixed dummy
1849 SUTRS record if your client requests SUTRS.
1851 Documentation updated accordingly.
1853 You can now set external libraries and RANLIB support in the top-level
1857 First public release.
