3 Add missing definitions ZOOM_resultset_get_facet_field_by_index
4 and ZOOM_resultset_facets_names.
6 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
9 Change APDU dump printing to avoid long leading blanks. For levels 16
10 or larger the level is shown and the indentation is truncated but
11 recursed with modula 8. This makes it still reasonable easy to read
12 - even for nested BER dumps.
14 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
15 return 0 (incomplete package) in case where the BER package was
16 considered too nested (return value of -2).
18 dumpber: lines of level 15 are not indented further. Two spaces per
19 indentation; indentation 15 or more is indented to a fixed indentation
20 and augmented with a level=<no> indication.
22 zoomsh: increase max size of command+args
24 GFS: No limit in RPN buf size in CQL to RPN conversion.
28 New function for daemon utility, yaz_daemon_stop .
30 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
34 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
35 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
39 YAZ daemon utility relays SIGUSR1 to child process.
41 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
42 would result in en empty database list - which in turn would result in
43 encoding failure for search.
45 Fix reading beyond string in yaz_sort_spec.
49 Add two new SRU diagnostics:
50 236: Access to specified database denied
51 1015: Init/AC: Maximum number of simultaneous sessions for Userid
53 Document the very useful ZOOM-C option "apdulog".
55 CQL to RPN: term may be passed through verbatim. This is enabled with
56 truncation.cql . The assumption being that the term is already CQL.
60 record_conv: leader spec may be given for marc element.
61 The leader spec is given as attribute leaderspec for element marc.
62 For example to convert a MARC21 record from MARC-8 to UTF-8:
63 <marc inputformat="marc" outputformat="marc"
64 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
66 record_conv: allow user-XSLT params. For example:
67 <xslt stylesheet="MARC21slim2DC.xsl">
68 <param name="myparameter" value="myvalue"/>
69 <param name="otherparameter" value="othervalue"/>
72 record_conv: fix error handling for missing marc charsets.
74 CQL: fix extra terms in wrong order.
78 record_conv: modify new API for conversion types. The conversion types
79 may be passed in new functions yaz_record_conv_configure_t and
80 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
82 Avoid mixed statement/variable declare; fixes compilation with Visual
87 Add non-standard SRU diagnostic: 235: "Database does not exist".
88 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
89 Update SRU to Bib-1 diagnostic maps accordingly.
91 CCL: add two new diagnostics for unsupported masking. The new
92 diagnostics are: "Embedded truncation not supported" and
93 "Single charcacter mask not supported".
97 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
101 Build YAZ for Ubuntu Oneiric.
103 CCL: allow parantheses for proximity operands. For example CCL query
104 (a) % (b) is now allowed.
106 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
107 marked dead, rather then being destroyed. If not, the session memory is
108 being free'd before the search/scan handler is finished. Also destroy
109 'request' memory in request_release rather than in various places,
110 which resulted in leaks from time to time.
112 --- 4.2.24 2011/12/21
114 cql_sortby_to_sortkeys: honor sort prefix.
116 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
117 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
118 The rpn2cql family of functions now always returns quoted CQL terms.
120 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
122 --- 4.2.23 2011/12/15
124 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
125 sequence is treated as one. For example, &&a=b&&&c& is identical to
128 --- 4.2.22 2011/12/05
130 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
131 APDUs for a connection to a WRBUF.
133 --- 4.2.21 2011/11/23
135 Fix cql_sortby_to_sortkeys. Completely broken before.
137 Make CCL's @truncation work again.
139 --- 4.2.20 2011/11/09
141 New ZOOM connection setting: tproxy. It's like proxy, but does not
142 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
143 to set resolved address + port for a connection outside ZOOM itself.
145 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
147 --- 4.2.19 2011/11/07
149 Fix uninitialized variable in Solr spell support (could cause SEGV
150 for SRU response decoding).
152 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
153 back-end's addinfo through into the ZOOM response addinfo.
155 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
156 they are separated by a colon and a space rather than simply
159 --- 4.2.18 2011/10/28
161 Add support for Solr spell-checking/suggestions through ZOOM.
162 If a Solr target has been configured correctly for spelling-checking
163 and suggestions, these will now be returned on the ResultSet option
164 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
166 --- 4.2.17 2011/09/28
168 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
169 with a flag whether to substitute escape sequences or not.
171 --- 4.2.16 2011/09/22
173 Fix nmem_strsplit_escape to substitute escape char properly.
175 New option for zoomsh -e , which makes it abort on first error and
176 return process exit code to indicate success/failure.
178 YAZ options utility supports special option -- which makes all it treat
179 all following arguments as non-options.
181 --- 4.2.15 2011/09/16
183 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
184 searched if absolute filename is given.
186 Fix conv_xslt() error-reporting when stylesheet is not found.
187 (The value of fullpath is meaningless in this situation.)
189 --- 4.2.14 2011/09/07
191 Fix problem in CQL sort node creation: un-initialized memory.
193 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
194 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
195 CQL sortby depending on whether Type-1 or CQL is actually sent to the
198 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
199 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
201 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
202 will make it possible to use both single-character mask (#) and wildcard (?)
203 in CCL . Throw diagnostic for left truncation because that is not supported
206 --- 4.2.13 2011/09/01
208 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
209 cases using escapes (\-sequences) and masking.
211 PQF parse fix: A trailing backslash followed by end-of-string (\0)
212 would result in a read one byte beyond string.
214 rpn2ccl may use Z39.50 masking for terms (t=z).
216 ICU check fix. Don't include library -lCrun on Solaris, unless present.
218 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
219 not --cppflags (which seeems like an error in icu-config).
221 --- 4.2.12 2011/08/27 RPM package only
223 cql2ccl: fix conversion of terms: operator characters were not
226 --- 4.2.11 2011/08/25 RPM package only
228 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
229 CCL parser will map both # and ? to their regular expression
230 quivalents (. and .*).
232 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
233 of reserved CQL characters.
235 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
236 is, so that they are passed through.
238 --- 4.2.10 2011/08/24
240 ZOOM SRU mode: more aggressive re-connect.
242 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
243 made available as a utility function, declared in <yaz/logrpn.h>
245 rpn2cql_structure() supports proximity nodes (except that the Type-1
246 proximity node's "exclusion" binary is ignored, as there is no way to
247 express that in CQL). Fixes bug #4564.
251 Fix SEGV that could occur if set command of zoomsh was given without
252 value (2nd argument).
254 Fix SEGV that could occur if unsupported transport was given for
255 COMSTACK - say https (when SSL was unavailable).
257 Build yaz-url on Windows too.
261 New utility to get web content. Header is url.h. A command line tool
262 yaz-url is part of the distribution and packages.
264 Fixes for SSL COMSTACK (when gnutls is in use).
266 New functions yaz_base64{encode,decode}. Header is base64.h.
270 ZOOM C includes HTTP response buffer as additional info if it fails
271 to decode the SRU response.
273 Make wrbuf_json_puts available.
277 zoom: throw diagnostic for invalid value for option "sru". Before a
278 bad SRU request was sent.
280 Adding new utility wrbuf_vp_puts.
282 Add cclxmlconfig.obj to win/makefile. It was missing completely.
286 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
287 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
288 redirect was used at the same time.
290 MARC line mode decoding: be less picky about length given - first
291 5 digits of header that is.
293 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
295 Changes to decoding of SRU records: a record with recordPacking=xml is
296 modified with a new root element <yaz_record> if the recordData contains
297 multiple children elements. This is to make the record XML parseable
300 RPN to SOLR conversion: encode special characters.
302 Generic Frontend Server: fix uinitialized member, stepSize.
306 Fix a bug in SRU decoding of records.. The database records stored
307 had un-initialized memory, but it would only be seen with yaz_record_render
308 and type_spec="ext" .
310 Fix a bug in ccl_qual_dup introduced in 4.2.3.
314 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
318 Add new utilities to convert from CQL to CCL . These utilities have
319 prefix cql_to_ccl defined in cql.h.
321 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
322 lead to memory heap corruptions when ICU utilities were in use.
326 Make compilation work without Libxml2.
328 yaz-client: remove redundant blanks in display of searchResult-1 term
333 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
334 resulting CQL node (tree) in a new node CQL_NODE_SORT.
336 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
337 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
338 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
339 Note that the CQL sortby spec is only converted when the GFS is already
340 converting from CQL to RPN (cql2rpn element).
342 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
343 specify whether to collapse delimitors or not. The existing nmem_strsplit
344 do collapse (collapse parameter = 1).
346 Windows installer: For NSIS, set InstallDir depending on x86/x64.
348 Rename internal func yaz_use_attribute_create. While non-static, this
349 function is not declared in a public header.
353 Add -lCrun when linking with ICU on Solaris.
355 More quicks character set conversions for OPAC records.
359 fix problem with record_render: records were converted (character set
360 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
364 SRU: add methods for handling DADS SRU-proxy facets.
366 Separate OPAC record character set for ZOOM_record. yaz_record_render
367 allows a character set given as charset=from/opacfrom,to where 'from' is
368 the character set of a bibliographic record, 'opacfrom' is character set
369 of OPAC record and 'to' is the target character set.
373 yaz-client: show may XML format records. Command show followed by 'format'
374 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
377 src/stemmer.c: Avoid using unnamed union. It is not supported by some
380 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
383 Update yaz.spec to operate on both SLES11 / Centos 5.5.
385 RPM: Release includes 'indexdata' name. Use indexdata in release name so
386 this package can be distinguished from other vendors.
388 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
389 as determined by configure
391 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
393 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
394 returns no error and no record, the present request is considered
395 partial (only a subset of the records could be returned by backend), and
396 so it is appropriate to set Present Status to partial-4.
400 Move yaz-config man pages to section 1.
402 More documentation about SOLR.
404 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
405 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
406 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
407 peers on some Linux systems. However, in general that does not work
408 so YAZ can not rely on that to work. Debian changed behavior in this
409 respect from Debian lenny to Debian squeeze (still testing as of Oct
411 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
413 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
417 Fix yaz-config output: echo_source not set correctly by configure.
421 SOLR WebService support for yaz-client and ZOOM.
423 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
425 --- 4.0.12 2010/08/17
427 Z39.50 facet support. Facet specifications are passed for search in
428 other-information with ASN.1 as defined in facet.asn and OID
429 .10.1000.81.5 . Facets are expressed as an Attribute list as known
430 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
431 3 is limit (number of entries to get in response). yaz-ztest returns
432 dummy facets if a client asks for them.
434 --- 4.0.11 2010/07/09
436 CCL fixes: bug 2895 and bug 3539.
438 GR1-display: add comma in display - was removed by mistake in
441 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
443 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
445 --- 4.0.10 2010/06/18
447 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
448 result set from a connection. The result set will be on its own
449 thereafter; no operations on it will perform retrievals from a target.
450 Only cached copies are returned.
452 ZOOM C:fix case for HTTP servers responding with Connection:close.
453 Ensure that if there is a current task it is resumed (like fetching
454 more records in a result set) . Bug #3484.
456 PQF parser: use odr_atoi for Odr_int (not atoi)
458 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
459 values that contain any non-digits are treated as string attributes
460 (previously decoding only checked for leading character ([0-9]). PQF
461 encoding: attribute string values are not surrounded by double-quotes.
465 New utility for managing threads - thread_create.h.
467 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
468 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
469 but YAZ' implementation do.
471 Fixes for yaz_cond-functions on Windows 7.
473 DLL export more symbols.
475 zoomsh: show record do NOT render opac.
477 Remove *.la files from Debian and RPM packages.
481 Debian package libyaz-dev depends on libgnutls-dev again (was
482 removed in YAZ 4.0.6, but due to Libtool it is still needed
483 even though yaz-config do not list libgnutls libs).
485 ZOOM: Use only one WRBUF for returning string results for
486 ZOOM_resultset. Reduces memory usage for ZOOM in general.
488 ZOOM: ZOOM_connection do not use a shared pointer to
489 ZOOM_resultset after ZOOM_resultset is destructed by
490 user. Reverts to YAZ 4.0.4 behavior.
494 record-conv: fix problem with at least one XSL conversion -
495 due to probably incorrect usage of XML XSL documents.
499 Fix yaz-config for static mode and the use of SSL (gnutls).
503 Forward decl timeval struct in mutex.h and gettimeofday.h.
505 yaz-config: fix 'static' mode linking.
509 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
510 are wrappers for pthreads or Windows. For Windows these are put in
511 a separate DLL: yaz_cond4.
513 libyaz.la (whole source) is compiled with thread. If thread support
514 is enabled enabled, all source of YAZ is compiled with treading support.
515 This allows core utilities such as yaz_log to use thread facilities.
516 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
517 thread utilities. This commit moves mutex utilities (mutex.c) from
518 libyaz_server.la to libyaz.la.
520 yaz-json-parse displays leading text until error.
524 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
525 patch from Giannis Kosmas.
527 SRU: no longer URL encode SRU database. The URL for an SRU server is
528 a URL and such is alreeady encoded - at least when given with leading
529 http:// or https://. This reverts behavior to YAZ 3.0.50.
531 Support for new MARC XML notation TurboMARC which like MARCXML is a
532 complete representation of MARC/ISO2709.. This one, however, is more
533 compact and allows for faster processing with XSLT. TurboMARC can be
534 used in the marcdisp.h API, from the yaz-marcdump utility and from
537 yaz-ztest can be configured - via the database - to perform certain
538 delays when it performs operations search, present and single record
539 fetch. This allows testers to make yaz-ztest act as a real or even slow
540 Z39.50 server. Refer to the yaz-ztest man pages for details.
544 wrbuf_destroy allows NULL WRBUF passed to it.
546 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
548 Add ZOOM_connection_close.
550 No fixed size buffers for ZOOM shell - bug #3257.
552 tstodr: make it work on s390 platform.
554 New icu iterator-functions. The new icu_iter-functions makes it possible
555 to use ICU chains from many threads.
557 yaz-client: better syntax check for show command.
561 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
564 New simple local-file XML include facility which allows file glob-patterns.
565 Refer to yaz/xml_include.h.
567 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
570 ZOOM_record_get supports new parameter "format" which makes it format XML
573 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
574 JSONText in ECMA-262) is JSONValue, not JSONObject.
578 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
579 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
581 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
582 POSIX/Unix builds .so with major version 4.
584 Remove old LOG_-defines from log.h. They have been obsolete and
585 undefined by default for the last 5 years.
587 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
589 GFS: Remove socket (int *fd) from search_rr handler. The socket
590 descriptor ptr is a facility that allowed a search handler to supply
591 a socket which would serve as a callback - when search was complete.
592 This facility has now been in use for years.
594 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
595 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
596 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
597 returns 'const char *' rather than 'char *. The returned string is
598 read-only and should not be modified by applications. COMSTACK cs_close is
599 now a void function - it no longer returns int. No applications check for
600 the value and the implementations has always returned 0.
602 ZOOM: use size_t for scan hit counts and str size. Functions
603 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
604 occ (hit count) and len (string length) are now of type size_t pointer
605 rather than int pointer. This is to be able to represent large hit counts
606 and to also just to use the proper type for string length (strlen result).
608 New JSON parser. Refer to include/yaz/json.h .
610 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
611 Used to be int in some cases. Many wrbuf_-functions used to return an int
612 indicating some length.. These return values were never used. And so they
615 ODR: odr_malloc, odr_total now takes size_t for size.
617 clone_z_type: fix leak; occurred for encoding failures.
619 --- 3.0.52 2009/12/03
621 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
622 bug was introduced in 3.0.51.
624 --- 3.0.51 2009/12/02
626 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
628 tcpip comstack: fix leak for getaddrinfo.
630 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
631 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
632 Decoding of SRU "path" database is performed by private function
633 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
634 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
636 yaz-client: honor base command for SRU. Change when database setting
637 is applied for SRU and ensure it is kept when a connection is reset.
638 Change also the way errors are displayed or SRU (decoding of packages).
640 --- 3.0.50 2009/11/02
642 Add support for extra request / response data for SRU codecs and GFS.
643 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
644 for extra data response buffer and length. For the GFS, both request
645 and response data (XML) is carried in extra_args and extra_response_data
646 for the search handler. Patch by Ko van der Sloot.
648 ZOOM: For queries that cannot be converted to the specified rpnCharset,
649 ZOOM now returns a diagnostic on the client-side ('invalid query' /
650 10010). This fixes bug #2113.
652 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
653 cmdfile included a 'quit' command that would result in a memory violation.
655 --- 3.0.49 2009/10/01
657 Make a number of functions defined in xmlquery.c static. These have
658 never been declared in a public header file (yaz/xmlquery.h) and was
659 made public by mistake.
661 Improve speed of character conversions (iconv utilities). This makes
662 conversions from MARC-8 faster.
664 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
665 unless type desired is "raw". This will prevent type "xml" from
666 returning ISO2709 .. Which obviously can not be XML parsed.
668 Fix memory leak in ZOOM that would occur if option apdulog was used
669 on a re-used connection.
671 Frontend server logs HTTP requests.
673 Frontend server now sends Z39.50 close when it times out (sesssion has
674 been idle for too long). Versions 2.0.30 and earlier also sent close.
675 But due to a mistake this was disabled in all versions after that, i.e.
676 the server would just close the socket immediately.
678 yaz-client emits a better message when receiving an unrecognised
679 userInformationField.
681 Skip zero-length subfields when decoding ISO2709. This rare case happens
682 if a record has two FS characters in a sequence. Without this patch
683 there would be a reference beyond char array in using_code_len fragments
686 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
688 --- 3.0.48 2009/08/28
690 The show command offered by the zoomsh command now takes a 3d optional
691 parameter type which is what is passed to ZOOM_record. If the type
692 argument is omitted, "render" is used.
694 RPN to CQL conv may use USE string attributes (bug #2978).
696 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
698 --- 3.0.47 2009/07/08
700 Function yaz_xml2query allows a diagnostic element in the PQF XML
701 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
702 code and additional info respectively.
704 The BER BOOLEAN is now the integral type Odr_bool which still happens
705 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
706 typedef'd to Odr_int. This is still an integral 'int', but it may be
707 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
708 ASN-1 compiler as well as programs has been updated to use the new types.
710 --- 3.0.46 2009/06/08
712 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
713 only the bibliographic record was rendered. For type=opac, an OPAC
714 record is only returned if it is present.
716 iconv: small fix for encoding of advancegreek.
718 yaz-client: avoid double display of SRU/SRW records (bug #2798).
720 yaz-client: option auto_reconnect=on really reconnects.
722 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
724 server: avoid null ptr ref for for yaz_poll errors.
726 build: fix RPM build for RHEL 5.3.
728 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
730 --- 3.0.45 2009/03/31
732 Fixed bug #2709: TCP connect returns Invalid argument.
734 Fixed compilation for mingw.
736 Honor charset for raw records (ZOOM_record_get).
738 Fixed use of errno for threaded mode that was seen on Solaris 10.
740 Fixed argument passing with blanks in value for Windows Service.
742 Disable YAZ' own log rotate by default (no 1 GB limit).
743 The variable l_max_size which specifies the log file limit is set to 0
744 (DISABLED): This is due to the fact that YAZ is most often deployed using
745 logrotate. Also YAZ can not perform log rotate because of unsufficient
746 permissions (setuid).
748 --- 3.0.44 2009/02/17
750 List supported encodings in man page for yaz-iconv.
752 Fixed missing SSL libs for --libs output
754 Re-established OID record syntax application-xml. Nobody should use it
755 but we don't want to change soname because of this symbol being absent.
757 --- 3.0.42 2009/02/02
759 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
761 Added member named_result_sets for init handler struct for the GFS. This
762 allows a server to disable named result sets.
764 Removed OID record syntax application-xml.
766 Added support for rule-based transliterator for ICU wrapper of YAZ.
768 Fixed bug #1902: yaz-icu XML output.
770 Make YAZ checks Emacs friendly.
772 BITSTRING value shows value. Bug #2346.
774 ISO2709 decoding: skip control characters from indicator data.
776 Omit sort key by default in yaz-icu's output.
778 Allow combined single char options (again) for YAZ' options function.
780 Utility yaz-marcdump got option to display YAZ version (-V).
782 Allow YAZ to use ICU 3.4.
784 Added new ICU test case which illustrates removal of diacritics.
786 --- 3.0.41 2008/12/29
788 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
790 --- 3.0.40 2008/12/29
792 For configure, using option --without-xml2 also disables Libxslt/Libexslt
795 Fixed bug #2352: yaz-marcdump crashes for certain record.
797 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
799 Added support for Danmarc2 to UTF-8 conversion.
801 Added support for ISO5426 to UTF-8 conversion.
803 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
804 implementation version.
806 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
808 --- 3.0.38 2008/11/10
810 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
811 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
813 ZOOM C now interprets databaseName option for ZOOM connection as path
816 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
818 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
820 Dummy Libxml2 types no longer defined in headers of YAZ'.
822 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
825 --- 3.0.36 2008/09/26
827 Various ODR chapter fixes.
829 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
831 Added missing source for Windows compilation, mutex.c.
833 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
835 For SRU connections in ZOOM all records up to "count" are now fetched.
837 Fixed crash in generic frontend server (and yaz-ztest) which occurred
838 in Windows due to bad error handling for Libxml2.
840 Added facility for sending arbitrary records (ASN.1 any) using
841 ZOOM C's Extended service update. Patch by Sam Reynolds.
843 New options for ZOOM C's connection, logapdu which makes ZOOM log
846 --- 3.0.34 2008/06/18
848 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
850 --- 3.0.32 2008/06/12
852 Fixed memory violation that could occur when decoding UTF-8. This bug
853 was only present in 3.0.30 of YAZ.
855 --- 3.0.30 2008/06/06
857 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
858 GNU TLS is used by default (if found).
860 yaz-ztest returns OPAC records if a client asks for OPAC.
862 Improved speed of MARC-8 encoding.
864 Added support for lossy and loss-less MARC-8 encoding.
866 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
868 Added new Windows Service wrapper (sc).
870 yaz-client's itemorder command may now send a file.
872 Fixed yaz-marcdump to allow the use of NS prefix for record element.
874 Added new function yaz_log_xml_errors.
876 Allow (but warn) unknown XML attributes in MARCXML parsing.
878 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
880 The UTF-8 to MARC-8 conversion now uses a different set of characters
881 for Greek symbols. Bug #2120.
883 --- 3.0.26 2008/02/21
885 Added yaz_daemon (daemon.h).
887 Fixed bug #2068: pkg-config trouble
889 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
891 --- 3.0.24 2008/01/28
893 Document --with-xml2 option.
895 Added OPAC XML XSD (etc/opacxml.xsd).
897 Allow glob mask for name attribute in retrieval element for the
898 generic frontend server's retrieval facility.
900 Changed yaz_poll_poll to return yaz_poll_except for all returned events
901 except POLLIN/POLLOUT.
903 Fixed error handling in cs_listen. Bug #2037.
905 --- 3.0.22 2008/01/20
907 Fixed version in yaz/yaz-version.h.
909 Fixed bug #2027: Crash when closing connection.
911 Changed configure so that ICU support is only enabled if only ICU
912 and Libxml2 is available (because the ICU chain is XML based).
914 --- 3.0.20 2008/01/15
916 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
917 is built. Only this DLL depends on the ICU runtime.
919 yaz-ziffy is no longer part of YAZ. It is distributed separately by
920 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
922 Changed license of CCL module to 'Revised BSD'. After consultation with
923 remaining members of the original EUROPAGATE consortium, we are re-issuing
924 the CCL module without a separate license. The software was developed by
925 Index Data as part of a research project. The special license was included
926 to help feed usage information back to the project consortium to support
927 project evaluation. At this time, the project consortium has long-since
928 disbanded, and the majority of the original principals have retired. At the
929 same time, we have significantly modified the software during the following
930 years, to the point where very practically no original code remains. To
931 simplify re-use of the software, we have contacted those members of the
932 consortium who could be reached, and agreed to re-issue the module as a
933 proper part of the YAZ package.
935 Tcl scripts uses /usr/bin/tclsh as preferred shell.
937 CQL closer to being version 1.2 compliant. CQL also allows free-form
938 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
941 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
942 bug could make Extended services handling crash in the ZOOM layer. This
943 bug was only present in YAZ 3.0.18.
945 --- 3.0.18 2007/12/19
947 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
950 yaz-marcdump reads and writes collection wrapped records.
952 Handle OPAC for record conversion module.
954 Fixes for ICU wrapper.
956 Allow ICU libs to be controlled with --with-icu .
958 --- 3.0.16 2007/11/12
960 Added yaz_poll which is a wrapper for select/poll. When poll is available
961 and non-buggy, it is used, by yaz_poll . This allows more than 1024
962 sockets to be in use.
964 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
965 functionality through an XML based configuration (ICU chain). This system
966 is useful for search facilities such as Pazpar2 and Zebra that needs to
967 perform tokenization of indexed material. The ICU code in a separate
968 library libyaz3_icu.a.
970 Added HTTP tunnel facility for COMSTACK, bug #1752.
971 This is a facility that allows a Web proxy, such as squid, to tunnel
972 Z39.50 traffic. This facility is "transparent" to must applications
973 using YAZ. It's enabled by using pseudo transport connect: followed by
974 the proxy address, followed by command, then follwed by he regular
975 "virtual" addresss. For example,
976 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
978 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
980 --- 3.0.14 2007/09/21
982 Fixed bad memory reference in ZOOM_record - cuased by member not being
983 initialized. This was a problem only in YAZ 3.0.12.
985 Fixed bug in conversion from MARC to XML: Non-XML characters in control
986 fields were not removed.
988 Changed the way C code is generated from codetables.xml. Made a MARC-8
989 conversion trie for each characterSet section rather than codeTable.
990 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
991 of codetables.xml from Larry Dixson, LOC. Bug #1464.
993 --- 3.0.12 2007/09/12
995 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
996 from ZOOM_record_error).
998 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1000 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1002 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1004 Better SRW-to-Bib-1 diagnostic mapping.
1006 ZOOM C and yaz-client announces SRU version 1.2 by default.
1008 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1011 Fixed in yaz_sru_decode to allow other version than 1.1.
1013 --- 3.0.10 2007/08/22
1015 Added support for SRU scan for ZOOM.
1017 Added support for the use of the older versions or Extended Service
1018 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1019 set to the version , 1=first, 2=second, 3=third. The third version is
1020 what ZOOM C has used so far. And that, obviously, is the default.
1022 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1023 therefore in Zebra and in SimpleServer-based applications). The new
1024 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1025 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1026 which is passed into the back-end search callback function.
1028 Added support for HTTP Basic authentication in clients: the SRU/W
1029 codec encodes the username/password elements of the PDU structure
1030 appropriately, and these may be set using the "user" and "password"
1031 options in ZOOM-C applications (the same options that are used for
1032 Z39.50 authentication).
1034 --- 3.0.8 2007/06/25
1036 Fixed bug #1208: SSL appears to be broken in ZOOM.
1038 Fixed bug #1206: Libxml2 include path weirdness.
1040 Added oid_name_to_dotstring.
1042 Allow elementSetName to be specified for ZOOM C record update.
1044 Allow waitAction to be specified for ZOOM C based for Extended Services.
1046 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1047 syntax OID. Bug introduced in YAZ 3 series.
1049 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1051 --- 3.0.6 2007/06/06
1053 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1054 directory. yaz-client now reads commands from file given by option -f
1055 if specified; then tries to read .yazclientrc in current directory.
1056 Failing that, it reads .yazclientrc from user's home directory.
1058 Added support for correlationInfo Note and ID for Record Update via
1061 Added yaz-client command querycharset which specifies character set for
1062 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1063 (termListAndStartPoint).
1065 Charset ISO5428:1984 is an alias for ISO5428-1984.
1067 Implemented a way to perform scan in a result set using Z39.50. This
1068 is achieved by attaching the result set name in the characterInfo
1069 (type InternationalString) of OtherInformation in the Scan Request PDU.
1070 The result set is identified in the otherinformation by the new OID:
1071 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1072 This allows for scan in result set and faceted search . Zebra did some
1073 of this in the APT term using attribute type 8 and value being result
1074 set. Using the OtherInformation approach for this is cleaner and easier
1075 to work with in proxies and the like. This facility can be used in
1076 yaz-client using new command setscan which takes a result set as first
1077 argument, start position (APT) as second.
1079 Changed decoding of SRU XML packed records to deal with servers that
1080 have recordData with XML data with multiple root nodes. Also make
1081 comparison for recordPacking case insensitive. Again, one server
1082 returns "XML" where others return "xml".
1084 For SRU responses allow Content-Type application/xml as well as text/xml.
1086 --- 3.0.4 2007/05/21
1088 Fixed bug in character set conversion of BER strings. Bug introduced
1091 --- 3.0.2 2007/05/08
1093 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1095 For OID class, use oid_class consistently.
1097 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1100 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1101 character set for bibliographic information interchange". By Giannis Kosmas.
1103 Added documentation on new OID API.
1105 --- 3.0.0 2007/05/02
1107 Changes to generic frontend server interface: added new member
1108 'query_charset' for bend_initrequest structure. A backend init handler
1109 should set this member to its native character set for query terms.
1110 When defined, the frontend server logic will announce this character set
1111 to a client if the negotiationModel bit is set by the client. All server
1112 implementors are encouraged to specify this. If a backend server does not
1113 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1115 Added CCL utility to remove terms (stop words) from resulting RPN
1116 tree. This is handled by functions with prefix ccl_stop_words_ .
1118 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1119 terms in RPN queries.
1121 Clean-up the CCL API. Moved some internal structures from ccl.h to
1122 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1123 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1124 This is replaced by ccl_parser_find_str which takes a string instead.
1126 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1127 libyaz.la is the core of YAZ except the generic frontend server and
1128 does not depend on POSIX threads anymore. libyaz_server.la is the
1129 generic frontend server facilities and uses POSIX thread functionality
1130 if available. The libyaz.la no longer depends on POSIX threads because
1131 the number of global structures is limited. NMEM no longer re-uses blocks
1132 between threads ; it simply free's memory immediately but allocates in
1133 "large" chunks as usual. We don't expect any performance penalties
1134 because of this. The yaz_log system is still using a global log_level so
1135 caution must be taken when modifying it with yaz_log_init_.. +
1136 yaz_log_mask_str. This, however, should not cause any trouble because
1137 these functions are called during initialization of application code
1138 anyway. `yaz-config --libs server` returns libs for server applications;
1139 `yaz-config --libs` returns libs for non-server applications.
1141 New OID database - with public definitions in oid_db.h. Removed old OID
1142 database including the head oid.h and definitions such as enum oid_value
1143 and struct oident. The new OID database uses the same string names as
1144 before but the 'protocol' is gone. There are now only two representations
1145 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1146 converts from string to OID; functions with prefix yaz_oid_to_string
1147 converts the other way.
1149 Change to emit_term() in CQL-to-PQF query translation: when a term has
1150 the /regexp relation modifier, do not process it for leading and
1151 trailing "^" and "*", which have quite different meanings in regular
1154 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1155 write handlers no longer carries a 'last' parameter. This will make
1156 yaz_iconv flush "less" characters. A flush is performed by call to
1157 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1159 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1160 removed, because function yaz_query_to_wrbuf does the same.
1162 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1163 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1165 Deprecated MARC utility functions removed.
1167 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1170 Branch split: YAZ_2_1_55_branch
1172 --- 2.1.54 2007/03/16
1174 Fix to ZOOM-C so that transparent reconnection is properly handled on
1175 connections that are in asynchronous mode.
1177 Fixed compilation on OpenBSD 4.0.
1179 Large strings in GRS-1 records are now properly displayed in yaz-client.
1181 Added character conversion support for "advancegreek"; based on patch from
1184 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1185 sequence is met. Before the error was not set so it would be unknown.
1187 Adjust yaz-marcdump MARC reader so that it skips until record separator
1190 --- 2.1.52 2007/03/07
1192 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1193 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1194 fd_set structure used as a bitmask for the FDs to be selected on.
1196 Using ACX_PTHREAD macro to check for POSIX threads.
1198 Fixed have-vsnprintf check.
1200 --- 2.1.50 2007/02/23
1202 Fixes for configure on BSD. Bug #900.
1204 Added snprintf/vsnprintf wrappers for systems that don't have
1205 limits (heavens forbid).
1207 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1208 created before all previous tasks were completed and removed from the
1209 task queue, the new task could be removed by a mistake.
1211 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1213 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1215 Fixed bug #832: Problem with MARC/charset in yaz-client.
1217 Fixed bug #668: save command line history for yaz-client.
1219 Fixed bug #830: pkg-config support.
1221 --- 2.1.48 2007/01/23
1223 Extended ZOOM result set options with two options that may be read by
1224 a client: resultSetStatus and presentStatus with values as specified for
1226 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1228 Fixed bug #827: Using SSL fails on Debian etch.
1230 Fixed bug #826: Weird looking chars for set of MARC records.
1232 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1233 that is treated as an ItemOrder with itemRequest being an XML document
1234 external. The value of "doc" is the content.
1236 Extended the GFS search facility. New member of bend_search_rr
1237 'estimated_hit_count' signals that hits is known to be an estmate
1238 (higher or lower than real hit count). New member 'partial_resultset'
1239 signals that the search was partial (hit count is lower or equal than
1240 real hit count). For Z39.50, the information is stored in resultSetStatus
1241 member of SearchResponse APDU. For SRU, the information is signalled
1242 via SRU diagnostic 59: "Result set created with valid partial results
1245 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1247 --- 2.1.46 2007/01/13
1249 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1251 Added ZOOM_connection_peek_event.
1253 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1254 the following new functions:
1255 ZOOM_event_nonblock, ZOOM_connection_process,
1256 ZOOM_connection_get_{socket,mask,timeout},
1257 ZOOM_connection_fire_event_{timeout,socket}.
1258 The existing blocking event handler, ZOOM_event, is a wrapper for the
1259 + blocking ZOOM_event_sys_{poll,select}.
1261 Implemented function ccl_xml_config which parses XML version of CCL
1262 configuration (bug #798).
1264 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1266 Added timings utility (yaz/timing.h)
1268 --- 2.1.44 2007/01/03
1270 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1273 Fixed bug #779: Rotation of apdu.log fails.
1275 Fixed for character set conversions:
1276 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1277 Honor G1 set in MARC-8 decoding.
1279 --- 2.1.42 2006/12/17
1281 Fixed bug #775: char conversion does not handle Alternative UTF-8
1284 Implemented function yaz_marc_read_line which parses MARC line format
1285 records. There is a wealth of formats out there. So far, this function
1286 reads line records produced by yaz_marc_write_line.
1288 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1289 more generic and easier to remember(!) options: -i format and -o format
1290 which specifies input format and output format respectively - where
1291 format is one of "marc", "marcxml", "line", "marcxchange".
1293 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1294 does not print anything except warnings for records.
1296 For yaz-marcdump, added support for MARC split into files (-s) with a given
1299 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1300 spec, at http://www.loc.gov/standards/sru/record-update/
1301 This has changed the binary layout of the following structs:
1302 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1303 bend_update_rr . Patch by Ko van der Sloot.
1305 Added GFS utility function bend_assoc_is_alive which returns 1 if
1306 association is still alive (client is connected); 0 otherwise (client
1307 closed connection). This allows busy servers to stop working for
1310 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1311 been a separate piece of software. This version of ziffy has been modified
1312 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1314 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1316 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1317 Client code may now interrogate options such as "init_opt_sort" to
1318 find out whether the server claims to support various options.
1320 --- 2.1.40 2006/11/27
1322 Added utilities yaz_{set,get}_esn to set/get element set name from
1325 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1326 of YAZ and has been so since YAZ 2.1.10.
1328 Implemented ZOOM_record_error which returns error information for
1329 record (surrogate diagnostic).
1331 --- 2.1.38 2006/10/31
1333 Updates for SRU Update by Ko van der Sloot:
1334 1. Changed name from "operation" to "action"
1335 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1336 versions in the code, marked as 'backward compatible'.
1337 3. Added diagnostics for SRU Update.
1339 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1341 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1343 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1345 For GFS, fixed problem with SRU diagnostic 'First record position out of
1346 range' being issued for 0 hits.
1348 zoomtst10 part of Windows Build.
1350 --- 2.1.36 2006/10/13
1352 Implemented yaz_filepath_comp which splits a path into file path
1353 components (required by Zebra 2.0.3+).
1355 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1356 BSD inspired license until now so this should not have any real impact on
1357 anybody. See http://www.opensource.org/licenses/bsd-license.php
1359 Fixed bug #687: Missing log lines.
1361 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1364 Fixed bug #689: SRU diagnostics to be added.
1366 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1367 whether a connection is idle (no more work do do).
1369 --- 2.1.34 2006/10/04
1371 Change type of optval from long to int for invocation of setsockopt with
1372 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1374 Added support for specifying the max log file size for the Generic
1375 Frontend Server. The size is given with option -r.
1377 --- 2.1.32 2006/09/21
1379 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1381 --- 2.1.30 2006/09/17
1383 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1386 Fixed bug in Generic Frontend Server that could cause a server to stop
1387 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1389 For the generic frontend server, the maximum record size is used as maximum
1390 size of incoming packages (SRU + Z39.50). The value until was previously
1391 only used in Z39.50 Init negotiation and, later, in a session controlled
1392 sizes of records returned. This is controlled using -k option. It can be
1393 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1395 --- 2.1.28 2006/09/04
1397 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1400 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1402 New option for yaz-marcdump -lpos=value which allows setting a portion
1403 of MARC header to a certain value.
1405 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1407 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1408 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1410 --- 2.1.26 2006/08/15
1412 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1415 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1417 --- 2.1.24 2006/08/08
1419 Fixed MARC ISO2709 encoding routines to deal with character set
1422 Minor changes to GFS logging. Database included in search request log
1425 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1426 cached/multiple records.
1428 Shared libraries are built by default on Unix+configure.
1430 Changed cql2pqf transformation to use a different evaluation order. The
1431 new order is: always, relation, structure, position, truncation, index
1432 and relationModifier. Old order was: always, relation, relationModifier,
1433 structure, index, position, truncation. Note that the the latter ones
1434 override former ones for identical attributes.. The new scheme means that
1435 it is possible to override any existing attribute with a relationModifier.
1436 And also that it is possible to override everything for the index rule
1437 (except the ones listed in relationModifier). No order is perfect but this
1438 one, we believe, covers more real cases.. The "always" should have been
1439 called "default", since the attributes there can be overridden with all
1442 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1443 compilation phase, but also for yaz-config --cflags output. This allows
1444 us to have public headers with Libxml2 stuff in them . It should also,
1445 eventually, make Libxml2 checks redundant in packages using YAZ, such
1448 --- 2.1.22 2006/06/15
1450 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1451 stored in uri, message and details.. Previously diagnostics were stored
1452 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1453 compatibility.. but he's probably the only one affected, so.
1455 Added support for CCL, compiled on the client side, in ZOOM-C. This
1456 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1457 input; the resulting query objects can be used for for searching with
1458 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1460 YAZ' configure searches for OpenSSL by default.
1462 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1463 SL_CTX_use_certificate_file. See
1464 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1465 for more info. Thanks to Ko van der Sloot.
1467 --- 2.1.20 2006/06/02
1469 Bug #600: SRU GET, POST support for yaz-client. Introduced
1470 command 'sru' which selects method SOAP/GET/POST.
1472 Allow missingValueAction to be specified for the sortspec string -
1473 function yaz_sort_spec. By default, the missing value action is null.
1474 Use ! to specify "abort". Use = followed by stringvalue to specify default
1477 Ensured that Present-handler (if defined) is called in GFS before any call to
1478 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1479 searchRetrieve requests.
1481 Documentation for YAZ is now based on the Docbook XML/XSLT using
1482 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1483 is no longer depending on jade/openjade or docbook-to-man scripts.
1484 PDF is no longer part of the distribution - but can optionally be
1485 made using DSSSL/jadetex or FOP.
1487 Added retrieval handling support in Generic Frontend Server to support
1488 conversion between MARC/XML as well as XSLTtransforms. See
1489 etc/yazgfs.xml for an example.
1491 Added Authentication support to Generic Frontend Server in SRU
1492 mode. Authentication using HTTP Basic is supported, as is the use
1493 of 'x-username' and 'x-password' parameters in the request itself.
1495 Added support for a new character set MARC8s identical to MARC8 except
1496 that it converts combined characters to single Unicode characters in the
1497 Latin-1 range (when possible).
1499 --- 2.1.18 2006/04/24
1501 ASN.1 compiler 0.4: generates brief Doxygen file header for
1502 generated .h/.c files.
1504 Utility yaz_iconv now supports conversion to MARC-8.
1506 New facilities for the MARC module. The reading - and writing of
1507 content are separate methods for the yaz_marc_t handle. The following
1508 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1509 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1510 format). Write functions have prefix yaz_marc_write_.. The existing
1511 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1512 available. Removed support for OAI-MARC and simplexml (not the
1513 simplexml from PHP5).
1515 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1516 to be returned for this connection.
1518 --- 2.1.16 2006/03/31
1520 Allow multiple languages and charsets to be specified with
1521 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1522 negcharset iso-8859-1,utf-8
1524 Translation of proximity nodes from CQL into PQF now works.
1526 Moved to automake 1.8, 1.9.
1528 Added function yaz_log_set_handler which allows a log handler to be
1529 installed. This handler will be called for all log messages. Output
1530 to file is also produced; but that can be disabled by passing NULL
1531 fname to yaz_log_init_file.
1533 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1535 For SRW (including GFS), accept application/soap+xml as content-type
1538 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1539 produces NO stylesheet reference even if a default stylesheet is specified
1542 --- 2.1.14 2006/03/14
1544 Updated Windows package to include yazd.dll + yazd.lib for the
1545 Development component.
1547 If the environment variable YAZ_LOG is set, then it is used as a
1548 string indicating the default level of logging to use if not
1549 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1550 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1551 used as before. So, for example, to omit warnings from YAZ logging,
1552 export YAZ_LOG=-warn
1554 cql_transform() now map structure and other attributes before indexes,
1555 so that index-specific structures and other attributes can override
1556 defaults. So now a combination of mapping specifications such as:
1558 index.dc.date = 1=date-modified 4=5
1559 does the right thing.
1561 cql_transform() now also respects the "always" mapping specification,
1562 which establishes an initial set of attributes to be used for all
1563 terms except where overridden by more specific attributes associated
1564 with the index, relation or modifier.
1566 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1567 which mode to use; one of "post", "get" or "soap" (SRW, default).
1569 Fixes for yaz_iconv routines: changed trie-based character set conversions
1570 to use only non-negative values for bit fields due to Sun's C compiler not
1571 supporting negative values.
1573 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1574 sequences where not read correctly. Fix by Rustam Usmanov.
1576 Updated win/makefile to use options, settings which makes things
1577 compile with VS C 2005.
1579 --- 2.1.12 2006/02/01
1581 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1583 In ZOOM socket code, use select instead of poll on MacOSX.
1585 ZOOM-C now support client-side compilation of CQL into RPN that is
1586 sent to the server, enabling CQL to be used against all Z39.50
1587 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1588 ZOOM_query object, and submit it using ZOOM_connection_search().
1589 The CQL-to-RPN translation uses a configuration file, the name of
1590 which must be specified in the Connection's "cqlfile" option.
1592 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1593 function, which takes as its start-term parameter a ZOOM_query object
1594 (which may have had either CQL or RPN set into it).
1597 --- 2.1.10 2005/11/29
1599 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1600 GFS to support this as well. Backend handler, bend_srw_update, does the
1601 update work. Code contributed by Ko van der Sloot.
1603 Allow retrieval of Search Result-1 information in ZOOM by the use of
1604 options that are attached to a result set. ZOOM documentation updated
1607 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1608 UTF-8 conversion. Patch by Raj Patel.
1610 Added option -m to GFS to control formatting of timestamps in log file.
1612 Added 'exit' as synonym for 'quit' in yaz-client
1614 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1615 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1616 for the new members. Patch by Ko van der Sloot.
1618 Added support for SRU POST. It is supported for content-type
1619 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1621 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1622 Instead make the library libyaz.la multi-threaded. Threading as a whole
1623 can still be disabled by configure option --disable-threads. Previosly,
1624 with older GLIBCs there were problems with MT libs under Apache. This
1625 has now been fixed a long time ago.
1627 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1630 CQL module modified to be case insensitive for relations/indexes/operations.
1632 Fixed bug in CQL transform code: incorrect value relationModifieder
1635 Added 'show all' command for yaz-client which retrieves all results
1638 Added new yaz-client, xmles, which takes a (private) OID and
1639 a document to be sent as an extended service request.
1641 Describe new yaz-client commands wait_response and set_auto_wait.
1643 Increase TCP/IP listener backlog from 3 (which I am guessing was
1644 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1645 that the socket will queue as many incoming connections as it's able
1646 to handle ongoing connections. In other words, it will never now
1647 refuse a connection that it would be able to handle merely because
1648 it's not got around to accepting() enough of the pending connections
1649 yet. This is the behaviour anyway under Linux, where the listen()
1650 argument is ignored; but not under BSD and on systems such as
1651 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1652 YAZ-based servers should now be uniform across operating systems in
1655 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1656 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1657 This allows yaz-marcdump to read large MARC batches (>2 GB).
1659 Modified all YAZ source files - except the source which is auto-generated
1660 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1663 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1664 corresponding to the existing *_setl() function. These allow option
1665 values containing arbitrary valuues.
1667 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1668 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1669 except that it returns an indicator of whether or not the sort
1670 criterion was accepted (0 for OK, -1 for invalid).
1672 --- 2.1.8 2005/06/07
1674 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1675 MARC output rather than returning "new" buffer.
1677 yaz-client warns about unknown init options.
1679 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1681 --- 2.1.6 2005/05/24
1683 Added support for SRW sort in Generic Frontend Server. Patch
1684 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1685 sortKeys - or NULL if none is provided.
1687 Fixed bug #307: It was impossible to specify indefinite/no timeout
1688 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1691 Added support for multiple languages and charsets to be specified in
1692 ZOOM. Each charset/language is separated by a blank. If negotiation is
1693 in effect in init-response, Option
1694 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1695 Code based on patch by Vasiliy Osadchuk.
1697 Fixed bug #306: infinite recursion that occurred when calling
1698 yaz_log_level_init as the first call (before other log level or
1701 Fixed bug in scan handling in front end server: if preferred-Position-In-
1702 Response was non-present, a NULL pointer referece was performed.
1704 --- 2.1.4 2005/04/26
1706 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1707 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1708 now defined for all those error codes. So instead of putting 109 in
1709 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1710 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1712 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1715 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1717 Program yaz-client now exits and produces an error message if multiple
1718 Z39.50 servers are specified on the command line (none or one allowed
1721 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1724 --- 2.1.2 2005/03/16
1726 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1728 Fixed bug #272: Preserve spacing for CCL terms.
1730 --- 2.1.0 2005/03/14
1732 Added support for virtual hosts and multiple backend servers for
1733 the YAZ frontend server. The configution is XML based and
1734 support specificition of CQL to RPN mappings and explain information.
1735 See section "Virtual Hosts" in the YAZ manual.
1737 Extended OPAC display utility. OPAC display utility renders
1738 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1739 to supplement yaz_marc_decode_wrbuf.
1741 Fixed a bug in MARC decoder that could caused it to crash for some
1742 invalid MARC records. More diagnostics and warnings where added in
1743 XML output (warnings, etc are stored in comments).
1745 --- 2.0.34 2005/02/08
1747 Fixes for UNIX domain sockets. Bug #261.
1749 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1751 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1752 Added yaz_marc_subfield_str which defines subfield lead string which is
1753 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1754 yaz_marc_endline_str which defines end of fields string used in
1755 YAZ_MARC_LINE format. Default string is newline.
1757 Experimental support for MarcXChange. This format can be produced
1758 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1759 http://www.bs.dk/standards/MarcXchange.xsd
1761 Added yaz-client commands scansize that sets maximum number of
1762 entries to be returned by scan.
1764 --- 2.0.32 2005/01/11
1766 Added support for SRW scan in yaz-client and Generic Frontend Server.
1768 * Added whereInList member to SRW Scan Term.
1770 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1772 Fixed NMEM system to return aligned blocks on the smallest boundaries
1773 that are suitably aligned for all possible types on the particular
1774 architecture YAZ is being built for.
1776 --- 2.0.30 2005/01/04
1778 Fixed numerious warnings that was issued with newer versions of GCC.
1780 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1781 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1784 Make YAZ Generic Frontend Server slightly faster.
1786 Enhance (and reduce) logging for Generic Frontend Server.
1788 Revert YAZ log system so that it flushes every write operation
1789 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1791 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1792 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1793 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1794 will effectively disable old definitions.
1796 --- 2.0.28 2004/11/09
1798 Added yaz_log_time_format which specifies log format using
1801 Added yaz_log_module_level which returns mask for a module. Value
1802 is non-zero mask a if module is enabled; zero if disabled.
1804 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1805 in include/yaz/cql.h.
1807 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1809 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1811 Fixed bug #172: RPM builds does not enable SSL.
1813 Doxyfile.in part of dist. Doxyfile generated by configure.
1815 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1816 are given and the corresponding component does not exist.
1818 Extend CCL documentation in YAZ reference. Describe r=r.
1820 --- 2.0.26 2004/10/01
1822 Fixed MARC->MARCXML conversion to properly deal with
1823 fields, subfields, indicators having non-ASCII characters.
1825 Fixed MARC->MARCXML conversion so that ASCII control characters
1826 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1829 Added YAZ GFS support for conversion from Z39.50 surrogate
1830 diagnostics to SRW surrogate diagnostics.
1832 Bug fix: YAZ GFS did not return schema in explainResponse.
1834 --- 2.0.25 2004/09/30
1836 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1837 now converts recordSchema to elementSetName as well as schema URI.
1839 Fixed bug in COMSTACK that prevented HTTP request packages from being
1842 --- 2.0.24 2004/09/29
1844 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1845 does not require white-space before and after the dash in a range, e.g.
1846 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1849 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1850 due to new GCC removing "redundant" code.
1852 Added yaz-client commands scanpos and scanstep that sets preferred
1853 position and step-size for scan.
1855 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1857 Added CCL utility ccl_qual_buf which parses one or more CCL
1858 spec lines in a buffer.
1860 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1861 of name and value - ignoring empty lines and comments.
1863 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1865 Added odr_get_element_path which returns current element path for an
1866 ODR handle. This utility is useful in error handling or user-defined
1869 Added ODR_PRINT utility odr_set_stream which is is a more generic
1870 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1871 to a write function and pointer to close function. The close function - if
1872 non-NULL - will be called during odr_destroy.
1874 Fixed bug in CCL parser where truncation char was not removed from
1875 right side when truncation=both was in effect.
1877 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1880 --- 2.0.23 2004/08/11
1882 Fix buffer overrun in CQL parser when dealing with proximity (%).
1884 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1885 to UTF-8/UCS conversion is now only based on codetables.xml.
1887 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1889 --- 2.0.22 2004/08/06
1891 Add support for more "commit changes" in ZOOM (uses Extended Services).
1893 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1896 Yet another small fix for configure of SSL.
1898 --- 2.0.21 2004/05/14
1900 Fix SSL libs for configure when --with-openssl=DIR is given.
1902 --- 2.0.20 2004/05/10
1904 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1906 SSL comstack now uses yaz.pem certificate file on server side
1907 by default. Certificate filename can be configured by calling
1908 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1910 Fix bug regarding multiple calls to ZOOM_connection_connect.
1912 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1914 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1915 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1917 ZOOM now allows inspection of X509 peer certificate for verification.
1918 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1920 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1921 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1922 as "modular" but it simplifies things.
1924 Added cs_get_peer_certificate to that returns peer X509 PEM.
1926 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1927 NULL if SSL is unavailable.
1929 Documentation about MARC decoding tools.
1931 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1933 --- 2.0.19 2004/03/30
1935 Rename CHANGELOG to NEWS to follow GNU style packing.
1937 Fix bug with missing initialization of member in init_diagnostics.
1938 This bug affects threaded version of GFS server.
1940 --- 2.0.18 2004/03/20
1942 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1945 Ensure zlib.dll is packed with Windows install.
1947 --- 2.0.17 2004/03/17
1949 Fix encoding of xsd:string to use text instead of CDATA.
1951 Fix endless loop in CQL parser with unbalanced ".
1953 Use a more compact way to store MARC-8 conversion tables.
1955 --- 2.0.16 2004/03/16 Debian only
1957 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1960 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1965 --- 2.0.15 2004/03/01
1967 Another fix for decoding of XML packed records.
1969 --- 2.0.14 2004/02/25
1971 Fixes for Chunked encoding. White space not ignored after length spec.
1973 Update NS and use default NS for SRW diagnostic elements.
1975 --- 2.0.13 2004/02/23
1977 Implement ZOOM_resultset_cache_reset which resets record cache.
1979 Implement ZOOM_resultset_sort which sorts a result set.
1981 Implement chunked HTTP transfer.
1983 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1985 --- 2.0.12 2004/02/16
1987 Added member 'schema' to bend_explain_rr structure so that backend
1988 can specify explain record identifier. Defaults to Zeerex 2.0.
1990 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1992 --- 2.0.11 2004/02/16
1994 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1997 Added init command for yaz-client which sends "extra" init request.
1999 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2000 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2002 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2004 Make ZOOM error code for "invalid query".
2006 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2008 --- 2.0.10 2004/02/05
2010 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2013 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2015 Added option -p <file> to make Generic Frontend Server to write PID file.
2017 Added option -D to put Generic Frontend Server in background on its own.
2019 Make ZOOM C recognize option "password". If unset, "pass" is used
2020 (for backwards compatibility).
2022 Fixed a bug in Generic Frontend Server that could make it crash if a
2023 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2026 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2027 Must be issued before open, in order to be in effect.
2029 --- 2.0.9-6 2004/01/12 Debian/Windows
2031 Make the SRU server more picky WRT unknown params, etc.
2033 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2035 New YAZ client command, options, that sets Z39.50 options.
2037 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2038 options from a string of tokens (one token for each option bit).
2040 Update SRW diagnostic code messages.
2042 --- 2.0.9-5 2004/01/07 Debian/Windows
2044 Handle user defined stylesheet for SRW/SRU.
2046 --- 2.0.9-4 2004/01/06 Debian/Windows
2048 Fix bug in decoding of Content-Length.
2050 --- 2.0.9-3 2004/01/06 Debian/Windows
2052 Fix a bug with decoding of XML packed records.
2054 --- 2.0.9-2 2004/01/05 Debian only
2056 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2058 Fix bug in SRW/SRU diagnostics decoding.
2060 --- 2.0.9 2004/01/05
2062 Fixed bug in Generic Frontend Server which could drop records exceeding
2063 preferred message size. Reported and fixed by Irina Dijour.
2065 Fixed calculation of package size for structured records in Generic
2066 Frontend Server. Reported and fixed by Irina Dijour.
2068 Fixed namespace for SRW/SRU diagnostics.
2070 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2072 --- 2.0.8 2003/12/22
2074 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2075 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2078 CQL changes to reflect recent changes to the specification:
2079 * Documentation talks about context sets instead of index sets.
2080 * Documentation talks about indexes instead of qualifiers.
2081 * The CQL-to-PQF transformer's configuration file now uses
2082 "index.set.name = <attributes>" instead of the old form
2083 "qualifier.set.name = <attributes>". (Both forms are still
2084 understood but the latter is deprecated.)
2085 * CQL terms with no explicit index specified are now interpreted as
2086 cql.serverChoice instead of srw.serverChoice (which of course
2087 behaves exactly the same.)
2089 --- 2.0.7 2003/12/16
2091 MARC conversion can now generate ISO2709 output in another
2092 character set. yaz-marcdump uses this facility if you invoke it
2095 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2096 functions from there can be used from C++.
2098 --- 2.0.6 2003/12/04
2100 Frontend server now transfers memory from decoded packages to stream
2103 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2104 references to show up.
2106 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2107 the ZOOM Abstract API. The older names for the same options are still
2108 also supported for the benefit of old applications.
2110 ZOOM-C supports "implementationId" and "implementationVersion" options
2111 to go along with "implementationName". These allow the user code to
2112 specify identification strings to be sent to servers.
2113 Add OID for the new ExtLite attribute set.
2115 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2116 as requested/supplid by Ere Maijala <ere@atp.fi>
2118 For generic frontend server, reverse the order of
2119 "toolkit-supplied / application-supplied" strings sent as implementationId,
2120 Name and Version. Also, remove the spaces around the slash. This brings
2121 the GFS in line with the behaviour of ZOOM-C on the client side.
2123 Add function ZOOM_scanset_display_term.
2125 yaz-client shows scan displayTerm if present.
2127 Utility yaz-iconv is now installed by default along with the man page
2130 Extend configure check for OpenSSL to use pkg-config where available (such
2133 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2134 server to specify uid/gid/mask for socket using the format
2135 unix:[user=uid,][group=gid,][umask=mask,]file=path
2136 If file= is omitted the existing format is assumed, e.g.
2138 in which case the mask is 0666 (rw for everybody).
2140 Major restructure of YAZ source. All source in libyaz is in src directory.
2141 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2142 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2144 Added man page for utility yaz-marcdump (used to be called marcdump).
2145 yaz-marcdump is installed by 'make install'.
2147 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2148 of incoming package failed.
2150 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2152 Change prototype of odr_perror: add const to message string.
2154 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2156 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2157 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2158 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2159 DNS lookup. There should not be any compatibility problems with this
2160 assuming that blocking=1 or 0 is used.
2162 Fix bad reference in UNIX comstack in function cs_addrstr.
2164 Fix for compilation on AIX.
2166 The generic front-end server (server/seshigh.c) now supports returning
2167 Init diagnostics to the client in User-information-field, in
2168 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2171 --- 2.0.4 2003/09/04
2173 Allow any CQL relation (not just all,any,exact,scr).
2175 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2176 that features the same UI.
2178 Implemented command update0 in YAZ client which is equivalent to
2179 update but uses old of Ext Update ASN.1.
2181 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2182 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2183 Previously no OID was used for this info.
2185 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2186 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2187 returns 'malformed search term' otherwise.
2189 SortResponse member resultCount now set to NULL in sort handler of
2192 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2195 Add three new utility functions for translating OIDs between various
2196 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2197 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2198 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2199 char *oid_to_dotstring(const int *oid, char *oidbuf);
2200 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2202 Reverted modifications for ES Update definition for z_IU0Update
2203 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2204 is back to YAZ 2.0.2.
2206 String value attributes for CCL parser.
2208 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2209 which their FirstSearch server returns in Init responses, sometimes
2210 carrying useful diagnostic information when Init fails. This has the
2211 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2212 "z39.50/oclcui.asn", where its definition is somewhat different from
2213 what OCLC document on their web-site, as required to interoperate with
2216 Support for anonymous authentication in yaz-client. Use the command
2219 * Fix the OID of the Index Data-local "admin" Extended Service from
2220 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2221 the 1000, which indicates a locally-defined OID, was a mistake.
2223 --- 2.0.3 2003/06/20
2225 Fix CCL directive @case handling so that it affects string match for
2226 both CCL keywords and qualifiers.
2228 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2229 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2230 Decoder has been updated with ASN.1 changes as listed in
2231 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2232 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2233 z_IUUpdate, remains unchanged.
2235 ZOOM_record_get may now return a record in a specific character set.
2236 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2237 "from" is the character set of record as returned by target. "to" is
2238 the character set to be returned. If omitted, "to" is UTF-8.
2240 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2242 New ODR utility, odr_getelement, which returns name of element for
2243 which encoding/decoding failed.
2245 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2246 in cases where a required element was omitted.
2248 Bug fix: some MARC8 sequences were not converted.
2250 New ZOOM option "step" which specifies number of records to be
2251 retrieved in one chunk. Used in conjunction with "start" and "count".
2253 SRW support for yaz-client. Use scheme http: to use it, e.g.
2256 yaz-client no longer does (un)intelligent character set conversions
2257 by default. Can be enabled with charset and marc_charset commands.
2259 xmalloc trace fix for 64-bit systems such as DEC alpha.
2261 Solaris 2.6 compile fix.
2263 New function, cql_strerror() translates SRW error codes, as returned
2264 by cql_transform_error(), into human-readable English strings. Used
2265 in yaz-client diagnostics when appropriate.
2267 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2268 converts it into a type-1 query which is sent to the server. This
2269 makes CQL available for use with all Z-servers, as opposed to the tiny
2270 minority that can handle CQL queries themselves.
2272 --- 2.0.2 2003/04/28
2274 New Debian package layout similar to the Redhat Package layout.
2276 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2277 and search result respectively.
2279 --- 2.0.1 2003/04/25
2281 Redhat package is now several packages: libyaz (runtime libraries),
2282 libyaz-devel (development and documentation, and yaz (utility programs).
2283 Package spec file by Morten Bogeskov.
2285 New member 'schema' in struct bend_fetch_rr which the name of requested
2286 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2287 handler MAY set this to reflect the schema of the returned record.
2289 New member 'display_term' in struct scan_entry. GFS now sets member entries
2290 and allocates scan entries to be filled by user scan handler. In previous
2291 version, entries member was allocated by the scan handler. That still works,
2292 but the GFS will ignore member display_term - assuming it was NOT set by
2293 the handler. The fact that the GFS now allocates the entries both allows
2294 for new members and makes a scan handler easier to write.
2296 Fix CQL lex buffer overflow.
2298 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2299 SRU default recordPacking is string.
2301 SRU protocol support for frontend server.
2303 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2305 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2307 Added scan for the ZOOM shell (zoomsh).
2311 * String Identifers for Schemas (Amendment 5).
2312 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2313 Old definition for schema
2314 Odr_oid *schema; /* OPT */
2319 Z_InternationalString *uri;
2320 #define Z_Schema_oid 1
2321 #define Z_Schema_uri 2
2324 * resultCount parameter to Sort Response (Amendment 1).
2325 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2327 Support for SRW 1.0 over HTTP. This is an optional feature and
2328 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2331 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2332 on the same port. SRW SearchRetrieveRequests are mapped
2333 to bend_init,bend_search,bend_fetch,bend_close.
2335 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2337 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2338 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2340 ZOOM connections are SRW based if schem http is used for hostname
2341 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2342 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2344 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2345 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2346 distance=n, order=true/false, relation=le, prox unit=word. If
2347 n is omitted, distance 1 is used.
2349 Fixed problem with C compiler include path in wrong order.
2351 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2352 on Solaris. Patch from Ko van der Sloot.
2354 New MARC decode API. All new functions operate on a yaz_marc_t
2355 handle. The most important new functions are: yaz_marc_create,
2356 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2357 decode and destroy respectively. Decoder can produce formats
2358 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2359 include/yaz/marcdisp.h.
2361 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2362 to UTF-8, UCS-32, wchar_t or Latin-1.
2364 * Prototypes for yaz_iconv_-functions moved to separate header
2365 include/yaz/yaz-iconv.h.
2367 Make a few private functions 'static' in unix.c. This prevents
2368 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2370 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2371 are set when Init Response is received.
2373 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2374 but returns diagnostic set as well.
2376 New function yaz_strerror which is a portable wrapper for
2377 strerror/strerror_r/GetLastMessage.
2379 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2380 is returned for MARC. If type is "oai", then OAI MARC is returned.
2382 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2385 --- 1.9.2 2002/11/26
2387 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2389 Fix bad race conditions on SIGTERM and terminate gracefully in
2392 Move retrieval (data1) module to Zebra since nobody seems to be
2395 Add GRS-1 render for ZOOM using same format as yaz-client.
2397 --- 1.9.1 2002/10/05
2399 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2401 Fix broken ESpec handling in data1 module.
2403 SGML reader parses comments and makes them part of the data1 tree.
2405 Added several type casts so that YAZ compiles as C++ code.
2407 ZOOM didn't handle PDU encoding failures properly.
2409 Added more Bib-1 diagnostics (approved extensions).
2411 GNU configure: better check for iconv.
2413 More portable use of accept, getpeername. Check for socklen_t. Use
2414 int/size_t if socklen_t is not defined.
2418 PQF parser rejects bad queries - including those with extra
2419 characters in them. PQF parser used to silently ignore that.
2420 Cleaner API for PQF added, which allows you to get detailed
2421 error information for bad queries (see yaz/pquery.h).
2423 Fixed bug in ZOOM_record_get for type "database".
2425 Implemented mini iconv library supporting conversions between
2426 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2428 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2430 --- 1.8.9 2002/08/20
2432 Fixed ZOOM C record cache so that preferredRecordSyntax and
2433 elementSetName is used to check for already fetched records.
2435 --- 1.8.8 2002/08/02
2437 Added three members in bend_initrequest structure to facilitate
2438 character set negotiation.
2440 Fixed a bug in frontend server that could cause indefinite
2441 loops under rare conditions.
2443 Revised character set utilities (charneg.h) so that encoding
2444 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2446 For PQF, directive @term <type> sets term type for Scan/Search.
2447 Here <type> is general, string, numeric, null. The term type
2448 is inherited - just like @attr.
2450 New call odr_set_charset that sets character set conversion for
2451 international-strings on a ODR stream. Prototype is:
2452 int odr_set_charset(ODR o, const char *to, const char *from);
2453 The InternationalString is still represented as C string in YAZ
2454 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2455 won't). On the protocol level, you can use any encoding.
2457 Support for UNIX sockets in ZOOM.
2459 Solaris recv sometimes returns errno == ENOENT. It is treated as
2460 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2462 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2463 both client and server. Code by Morten Bogeskov.
2465 --- 1.8.7 2002/05/22
2467 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2468 that they can be used directly from Visual Basic. You must recompile
2469 your windows APP if you're using ZOOM.
2471 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2472 Commands "lang" and "charset" sets language and character set respectively.
2473 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2474 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2476 Attributes from multiple CCL fields may be OR'ed rather than merged
2477 using directive "@field or". Fields are still merged by default -
2478 equivalent to "@field merge".
2480 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2483 Fixed bug in zget for parameter ExtendedServicesResponse.
2487 --- 1.8.6 2002/03/25
2489 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2491 Client displays USR.1:SearchResult-1 (hits per term).
2493 Additional Search Info for search in Generic Frontend Server.
2495 Fixed CCL parsing of "field=s".
2497 WIN32 installer - using the excellent NSIS software from nullsoft.
2499 Fixed CCL parsing of "field = - <number>".
2501 Added function yaz_marc_decode that decodes MARC for line mode
2502 display or XML (similar to that used by JZKit).
2504 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2505 Z39.50. But ISO/ILL was, however.
2507 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2508 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2513 --- 1.8.5 2002/02/03
2515 New YAZ client features: Command completion and new commands:
2516 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2517 Code provided by Jacob Poulsen.
2519 New call oid_trav, that visits all registered OIDs via callback.
2521 Function ZOOM_record_get now returns const char pointer rather than
2522 void pointer. It saves a lot of type casts.
2524 For YAZ client, command "auth" now allows you to set authentication
2525 in IdPass style. It is enabled when three tokens are given - order
2526 is user, group and password.
2528 Fix memory leaks in MARC record handling for ZOOM.
2530 New option for YAZ client, -k <kilobytes> that sets
2531 maximum record size. Similar to -k option for generic frontend
2532 server and yaz-ztest.
2534 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2536 Prefix query parser reports "fail" when bad attribute set is given.
2538 Fix in MARC decoder. Proximity logging. Fix for attribute set
2539 in scan handler for server. Patches by Shigeru Ishida.
2541 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2544 Configure option --with-openssl=<dir> now works when a directory is
2545 specified. Patch provided by Morten Bogeskov.
2547 New option for YAZ client, -u <auth>, that sets authentication.
2549 ZOOM fix: error information was sometimes "missing", since error
2550 was cleared/reset too when it shouldn't.
2552 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2554 --- 1.8.4 2002/01/04
2556 Scan for ZOOM API. New object ZOOM_scanset. New functions
2557 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2558 ZOOM_scanset_destroy.
2560 New ZOOM function, ZOOM_connection_last_event, that returns type
2561 of last event (such as "receive data", "send data", "apdu received",
2564 New ZOOM option, schema, that specifies schema for retrieval.
2566 New CCL feature. Qualifiers can be aliases for one or more
2567 other qualifiers (if more than one is given, OR is used).
2569 ZOOM uses named result sets if target supports it.
2571 Two new YAZ client commands: . (dot, which sources a script of YAZ
2572 client commands), and ! (to execute shell command.). Implemented
2575 Working on Debian packages.
2577 --- 1.8.3 2001/11/19
2579 YAZ client enables named result sets only if target supports it.
2581 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2583 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2584 with key="host" to get same result.
2586 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2587 Function Z3950_resultset_record(s) returns references to records
2588 "owned" by resultset. To become owner use Z3950_record_clone.
2590 Function z_ext_record handles Extended Services. Thanks to
2593 --- 1.8.2 2001/11/12
2595 CCL Parser fix: ignore token comma when dealing with and-lists.
2597 Documentation updates for COMSTACK.
2599 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2600 Changed prototype Z3950_records. For some functions, int parameters
2601 were changed to size_t.
2603 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2606 New MARC decode/display function, marc_display_exl, which properly rejects
2607 non-ISO2709 records. YAZ client uses it.
2609 --- 1.8.1 2001/10/29
2611 Fix bug: local attribute set wasn't set correctly in PQF strings.
2615 * Old Z39.50 codecs no longer supported.
2617 Added ZOOM C binding. See http://zoom.z3950.org/
2619 Renamed states for COMSTACKs to avoid confusion with events.
2621 Implemented cs_look and proper cs_rcvconnect.
2623 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2625 Configure detects POSIX threads on OpenBSD.
2627 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2628 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2630 When error is returned from present handler, non-surrogate diagnostic
2631 is returned in present response (and fetch handler is no longer called).
2633 * Minor adjustments to pquery parser (PQF). Token characters may be
2634 escaped by using backslash (C-style).
2636 PQF parser allows string attribute values to be specified. For @attr,
2637 non-numeric characters after the equal-sign are treated as strings
2638 (e.g. @attr 9=title).
2640 CCL trunction character may be defined (@truncation in file)
2642 * function zget_ExtendedServicesRequest sets waitAction to
2643 waitIfPossible (was wait).
2645 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2648 CCL operator names may be set in field definition files (CCL_bibset).
2649 See ccl/bib1 for an example.
2651 Fixes in ASN.1 compiler for C++ compatibility.
2653 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2654 and "op_or" to avoid conflict with C++.
2656 Fixed problem with GNU readline detection on Redhat 7.0.
2658 Added step-size for Scan backend handler.
2660 Fixed bug that made the frontend server crash when no attribute
2661 set was specified for scan.
2663 Front-end server automatically switches to original working directory
2664 when installed as an NT service. Previously -w had to be specified to
2667 Added extended attributes for retrieval module (data1), so that data1
2668 records carry d1_readXML/SGML attributes. d1_read also supports
2669 null-data rules ( <tag/>)
2671 On UNIX when POSIX threads are available, a separate library libyazthread
2672 is created. Programmers should link with that library and the yaz library
2673 when using threads. The reason for the split was that some applications
2674 on Linux, such as Apache, doesn't work well when using shared objects that
2677 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2678 (or any frontend server) in SSL mode by specifying ssl: followed by
2679 address. Only tested on UNIX.
2681 Added feature for CCL module. Virtual structure s=al or s=ol generates
2682 and-list and or-list respectively instead of phrase search.
2686 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2687 log_mask_str. This was done to avoid name conflicts with other libraries
2688 (such as other PHP extensions).
2690 Added raw OID member for preferred record syntax (request_format_raw)
2691 and returned record syntax (output_format_raw) for backend fetch method.
2693 Config file yaz-config now accepts options so that it returns specific
2694 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2696 Shared library support for UNIX using GNU libtool.
2698 * Modified backend interface. Request/Response struct's replaced by
2699 one read/write C struct. For example bend_fetchrequest and
2700 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2701 Every handler - even search has to be registered in bend_init
2702 handler. This means that the YAZ library no longer refers to
2703 external functions and it makes it possible to make the whole
2704 thing a single DLL/SO.
2706 Added Segment handler for backend server.
2708 Added Zmbol/Zebra administrative functions to YAZ client.
2710 Threaded frontend server on UNIX (when POSIX Threads are available).
2711 Starting the server with option -T enables multi-threading.
2715 Added configure option --enable-comp/disable-comp to control use
2716 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2717 located in sub directory asn.
2719 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2720 in ${exec_prefix}/bin along with the other programs yaz-client and
2723 GNU automake used to maintain makefiles.
2725 Added several OID's.
2727 Changed retrieval module so that we can load records with no abstract
2728 syntax defined. Tagpaths in these records are fully composed of string
2731 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2735 On UNIX, the generated makefile now supports a proper 'make install'.
2736 The prefix can be set via GNU configure to set the install location
2737 (default is /usr/local).
2739 * YAZ programs client and ztest were renamed to yaz-client and
2740 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2741 locations, such as /usr/bin,/usr/local/bin,etc.
2743 * YAZ Header files were moved from include to include/yaz. YAZ Header
2744 files are referred to as include <yaz/log.h> rather than <log.h>.
2745 The YAZ include path (-I ..) is therefore the same as before. Programmers
2746 should update their #include statements or use -Ipath/include/yaz
2747 instead. The main motivation for doing this change is that YAZ header files
2748 can be installed in "standard" locations /usr/include,/usr/local/include
2749 without introducing conflicts, since ALL YAZ header files are stored
2750 in subdirectory yaz (under /usr/include for example).
2752 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2753 rather than project/workspace files. We switched because project files
2754 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2757 Changed name of logging function, logf, to yaz_log, to prevent name
2758 clash with some math-log functions. The YAZ header log.h defines logf
2759 to yaz_log (#define) so there should be no incompatibilities by this
2762 Added bend_start/bend_stop handlers for server. These handler are
2763 called on start/stop of server. For windows they are called whenever
2764 a service is started/stopped.
2766 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2767 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2768 in util/yc.tcl. The auto-generated C code structures are, in a few
2769 cases, incompatible with the old decoders. There are differences in the
2770 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2771 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2772 The preprocessor variable ASN_COMPILED is defined when the compiled
2773 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2774 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2775 wish to use the old encoders/decoders you can specify --disable-yc
2778 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2779 version so that it supports both new - and old version of DB Update
2781 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2782 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2783 change. The name parameter can be set to 0 in which no name is specified
2784 for the construction. The macros odr_implicit and odr_explicit sets name
2785 parameter to zero for the construction involved. New macros
2786 odr_implicit_tag and odr_explicit_tag are similar to the others,
2787 except that a name parameter is added. For programmers' that don't use
2788 ODR they probably only need to change the call to z_APDU and z_External.
2790 Added access control facility by interfacing the TCP wrapper library.
2791 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2792 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2793 name of the daemon and enables the access control as specified in
2794 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2796 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2797 den Dool <H.M.vdnDool@kub.nl>.
2799 Added reference ID parameter to most functions in server API - refer
2800 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2802 Changed name of ccl library to libccl.a (was ccl.a).
2804 Fixed bug in decoder for Explain (Category TargetInfo).
2806 Added support for GNU readline in client. Thanks to Jacob Poulsen
2807 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2809 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2810 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2811 IMPLEMENTATION! This change was made to the development version before
2812 the ZIG decided to retract the amendment. If any users MUST be
2813 compatible with the original Update definition, PLEASE CONTACT US, and
2814 we will include a separate definition corresponding to the old Update
2815 ES. Note that because of the change to the ASN.1 of the
2816 TaskPackageRecordStructure we cannot define a single structure that
2817 will support both versions.
2819 * Added const modifier to buffer parameter for some ODR/BER encoding
2820 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2821 completeWAIS, odr_dumpBER.
2823 Fixed bug in client.c which caused a crash when a scanResponse didn't
2824 contain positionOfTerm.
2826 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2827 * will cause an error in a client if a non-YAZ target sends both a
2828 * list of Scan entries and non-surrogate diagnostics.
2830 Retrieval module enhancements. Tag sets may be typed in the reference
2831 to it. From the .abs-file the "tagset" directive takes a third optional
2832 integer type for the tag set referenced. From a .tag-file the "include"
2833 directive takes a third optional type as well. The old "type" directive
2834 in the tag set itself is still recognized but acts as the default type
2837 Backend interface change. Individual Scan terms returned from bend_scan
2838 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2839 in include/backend.h.
2841 Retrieval module enhancements. Multiple tag sets and attribute sets may
2842 be specified in abstract syntax specs. Revised the error/warning for
2843 logging messages reported by the retrieval module when reading the
2846 Object Identifier system (oid_..) changed. The API is backwards
2847 compatible but the oid-routines now allocates new OID's when needed.
2848 Raw OID's may be specified in oid_getvalbyname.
2850 YAZ now uses GNU configure to generate Makefile(s).
2852 * Minor changes in some of the member names of DeleteResultSetRequest and
2853 DeleteResultSetResponse. See include/proto.h.
2855 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2856 and added member 'languages' in TargetInfo (which was missing).
2858 Changed the way attribute sets are handled in the retrieval
2859 module. These are now cached, just like the abstract syntaxes
2862 Changed YAZ so that it links with compiled ASN.1.
2864 Added Explain-schema definitions and mapping routines. The following
2865 Explain categories have been implemented: AttributeDetails,
2866 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2868 Fixed minor bug in Windows version of Server Library.
2870 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2872 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2874 Added EXTERNAL: UNIverse Resource Report (non-standard).
2876 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2877 ENUMERATED and SET OF.
2879 * Added 'const' to some of the char pointer arguments for the
2880 functions, data1_read_node, data1_getelementbytagname,
2881 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2884 Fixed bug in data1_insert_taggeddata - the last_child member of
2885 parent wasn't initialised.
2887 * Changed data1_read_record and data1_read_node so that the supplied
2888 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2889 doesn't refer to any parts of the "SGML"-buffer.
2891 Fixed bug in server library (Windows version of statserv_remove).
2893 * Changed code so that it compiles as C++. The type definition
2894 of Odr_fun which is a member of Odr_arm was changed. The result is,
2895 that an explicit typecast is needed for the fun pointer when
2896 using Odr_arm - as in:
2897 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2899 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2901 Implemented the new structured date and time definition as approved
2902 by the ZIG. Added schemaId element to the specificTag in Espec-1
2903 (also approved at the last ZIG). Thanks to RVDM.
2905 Added some Object identifiers (RVDM).
2907 Changed the Update Extended Service (RVDM).
2909 Added command "refid" to client which specifies referenceId for
2910 the following requests.
2912 Implemented extended service handling for server. See ztest.c
2913 for an example as well as backend.h. New handlers are registerd
2914 in the Init handler.
2916 * Changed interface for sort in server.
2918 Added new members to statserv_options_block. It allows a server
2919 to read options from another source than just the command line. Thanks
2920 to Charles Woodfield.
2922 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2923 renamed to zboolean. Some C++ compilers complained about the name.
2925 Minor changes to gils.abs. Added index 's' (sort) on title
2926 and date/time-last-modified.
2928 --- 1.4pl2 1998/1/30
2930 Fixed bug in server library regarding inetd mode (-i). This bug
2931 was introduced by release 1.4.
2933 --- 1.4pl1 1998/1/29
2935 Added sort facility in client and backend server interface.
2937 Fixed problem with dependencies in Makefile(s).
2939 Fixed bugs for encoders/decoders of extended services and
2942 Implemented sub-tree feature for schemas. Sub-trees are
2943 referenced in *.abs-files. See explain.abs for an example
2944 of the use of this feature.
2946 Modified bib1.att; local attributes for ANY didn't include
2947 ANY itself (only affects use of the retrieval module).
2949 Fixed bug in plain SGML reader in function data1_read_node:
2950 tags with prefix "var" was incorrectly interpreted as variants.
2952 Added feature "sub-schemas" to enable references to - and definitions
2953 of - group of elements.
2955 * Removed member parent from type data1_element (in data1.h).
2957 Implemented function odr_nullval() that returns the value of
2960 * Removed member num_children from data1_node (in data1.h).
2962 Made NT service interface part of the server library. The
2963 function statserv_main uses the NT service when required and
2964 calls the statserv_start / statserv_close routines.
2966 Routine zget_SearchRequest and zget_PresentRequest fills
2967 resultSetName/Id member with "default" instead of "Default".
2969 Fixed memory leak in server. Request queue member wasn't freed.
2971 Fixed nmem_exit so that memory is freed.
2975 Revised the CCL parser utility to be thread safe.
2977 Added function, oid_ent_to_oid, to replace the function
2978 oid_getoidbyent, which is not thread safe.
2980 * Added nmem_init and nmem_exit to initialize and release
2981 NMEM resources. Function nmem_init should be called once in the
2982 initial thread before NMEM/ODR is used. statserv.c and client.c
2983 have been changed accordingly. The change was necessary to make
2984 NMEM thread safe. The NMEM memory pool is shared amongst threads
2985 in a process. Unix-based applications will still work fine without
2988 Added NT Services interface for the the Z39.50 (statserv) Server.
2989 Refer to the ztest.c source on the usage.
2991 Windows 95/NT port using MSVC5.0. Project files are included in the
2994 * Defined new 'global' handle for the retrieval (data1) system. The
2995 new handled, data1_handle, describes the state of the data1 system.
2996 This handle is passed as first argument to virtually all
2997 data1 related routines. The functions data1_create and data1_destroy
2998 creates and destroys a data1 handle respectively.
3000 Added ODR encode stream member to all backend request structures
3001 init, search, scan etc. This stream should be used to allocate all
3002 memory used for the response when thread safe operation is needed.
3004 Changed the comstack utility, cs_addstr, to be thread safe. The
3005 returned hostname string returned by the function is now part the
3008 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3009 function. The cs_straddr takes a COMSTACK handle as argument, so this
3010 function must be used after cs_create and before bind/connect.
3011 This function is thread safe.
3013 Moved test server to 'ztest' directory - generic server code still
3014 in 'server' directory.
3016 Made prefix query (pquery.c) utility thread safe.
3018 Added new function modifier YAZ_EXPORT to 'export' public DLL
3019 functions when using windows (see include/yconfig.h).
3021 Added definitions to the OID database (util/oid.c) (RVDM).
3023 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3025 Added call to ccl_rpn_delete in client program.
3027 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3028 release of RPN structure.
3030 Added support for C++, headers uses extern "C" for public definitions.
3031 With input from RVDM.
3033 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3034 Thanks to Ronald van der Meer (RVDM).
3036 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3038 Added support for private extensions to the OID database
3039 (oid_setprivateoids()). Thanks to RVDM.
3041 Added optional, physical ANY (key replication)
3043 Fixed null-reference problem in GRS-1 output filter.
3045 Proximity operator added to Prefix Query Format (PQF).
3047 In test client command "base" accepts multiple databases.
3049 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3053 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3055 Smallish bug-fixes in the new encoders/decoders (explain).
3057 Bug fixed in DeleteRequest.
3059 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3061 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3063 Added SOIF syntax (using private OID for now) to retrieval module and client.
3065 Added Update extended service.
3067 Added SearchResult-1 additional info structure.
3069 Added optional CCL (ISO8777) interpreter as separate module. Available
3072 --- 1.2 1996/6/10 (1st anniversary release)
3074 Added Summary record syntax. Lightly tested.
3076 Added OPAC record syntax. Untested.
3078 Added ResourceReport service encoders/decoders. Untested.
3080 Fixed bug in z_Unit - wrong tagging on unitSystem.
3082 Fixed bug in the DiagRecs decoder.
3084 Added options for max PDU size and session timeout to frontend-server.
3086 Added documentation of query-language parsers and other supporting utilities.
3088 [frontend-server] Added Attribute set to the bend_scanrequest API.
3090 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3091 surrogate diagnostics were generated.
3093 [retrieval] Allow multiple local values for attribute.
3095 [retrieval] Allow multiple attributes per element in .abs files. index type.
3097 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3099 --- 1.1pl2 1996/4/10
3101 Minor changes, mostly specific to Zebra's requirements (retrieval)
3105 Repaired bug in frontend server when running multiple listening
3106 endpoints in dynamic mode.
3108 z_External() now won't break if a known, ASN.1 value comes encapsulated
3109 in an octet-string. The value will pass through unmodified in an Odr_oct.
3111 Added a bit of code to the demo client to decode & display
3112 ASN.1-structured records represented in the octet-aligned branch of
3113 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3115 Added z_ext_getentbyref() to the ASN module. Doc updated.
3117 * Completed the SCAN definition in the ASN module. This may break SCAN
3118 code based on older YAZ-versions at compile-time. The fix is easy -
3121 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3122 under the SCAN definition. Remember to initialize this, server-people.
3124 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3125 that this does not extend to ODR and ASN.
3127 Comstack allows insertion of established socket (primarily for
3128 inetd-operation of servers). Doc updated.
3130 Front-end server can now start from the inetd in TCP mode. Doc
3133 --- 1.0pl4 1996/1/24
3137 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3138 the rank and record number.
3140 Adjustments to the frontend server.
3142 Fixed diagnostic BER dumper. It ignored the file argument.
3146 Various changes to retrieval module.
3148 Changed the union discriminators of the protocol files from enums to
3149 ints paired with #defines.
3151 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3154 *Changed operator in the RPN structure to 'roperator', again to avoid a
3157 Fixed problems in Explain decoders/encoders.
3159 --- 1.0pl2 1995/12/6
3161 Memory bug in log module fixed.
3163 --- 1.0pl1 1995/12/5
3165 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3167 Bug in Explain DatabaseInfo module fixed.
3169 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3173 The shift to v1.0 signals that we now consider the *core* functionality
3174 of YAZ reasonably stable (the core being more or less equivalent to
3175 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3176 tested (Explain not at all - though that will happen soonish).
3178 Minor changes to code to support Windows port.
3180 Various minor changes after we're getting to use GRS-1 & co. more.
3182 Added Espec-1 format.
3184 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3185 of the protocol and it cannot be selected when encoding (maps into 'string'
3186 when decoding). Needed to talk to some servers.
3188 Demo client can request simple element set names.
3190 Added Diagnostic Format encoders/decoders.
3192 Added simple Close handling to frontend server (no hooks for resource
3193 reporting yet), and demonstration client.
3195 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3197 --- 1.0b3 1995/08/24
3199 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3200 handled incorrectly when records were requested in the searchResponse. This
3201 will only affect you if you use the frontend-server.
3203 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3204 Test-client will ask for and print GRS1. Ztest will return dummy records
3207 Added Explain encoders/decoders to the service-level API. Untested.
3209 Added Extended Services: Item Order encoders and decoders to the Service-
3210 level API. Untested. We could use a recent copy of the pertinent bits
3211 of the ILL protocol to add those bits.
3213 Added diagnostic format 1 encoders/decoders to the service-level API.
3216 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3217 odr_cons.c, which causes a more correct output.
3219 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3220 was always set to 0 when no records were requested in the searchRequest.
3222 * Added better external-handling. This shouldn't harm old code that
3223 *encodes* externals. It can break code that looks for a
3224 'single-ASN1-type' representation, since those types that are known
3225 are now decoded immediately. Look at the SUTRS sample code in
3226 seshigh.c and client.c. Documentation updated.
3228 Handling of structured records in bend_fetchresponse. Length -1 marks
3229 structured record, type is deduced from format field.
3231 --- 1.0b2 1995/06/27
3232 Fairly quick maintenance release to add SUTRS support.
3234 Fixed handling of SUTRS records in the demonstration client.
3236 * Added format field to the bend_fetchrequest and bend_fetchresponce
3237 structures of the backend API (frontend server). When the record is
3238 returned, the value of the format field is mapped to an OID. The
3239 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3240 of the record. The special value VAL_NONE in the bend_request means
3241 that no specific format was requested by the client. Documentation
3242 updated accordingly. Test server (ztest) will return a fixed dummy
3243 SUTRS record if your client requests SUTRS.
3245 Documentation updated accordingly.
3247 You can now set external libraries and RANLIB support in the top-level
3251 First public release.
