3 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
4 global's SRU service uses a recordPosition scheme starting from zero.
5 First record's position should be one
6 according to the standard.
10 Allow more namespaces for SRU. This is to allow, for example, an
11 incorrect namespace returned from server
12 http://services.igi-global.com/sru .
14 Minor fixes for compilation on Windows.
18 daemon: log total number of bad signals from child on stop so that it
19 is more easy to spot problems with child worker processes.
21 retrieval: empty backend name attribute omits element set
22 from being used in retrieval.
26 Implement Solr sort strategy "solr", similar to sru11 sorting.
27 This will implement the correct parameters on Solr requst to do
32 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
35 MARC: Extra/missing indicator handled for MARCXML.
36 The indicator length is given in header and is the same for the
37 whole record. If attributes ind1, ind2 are missing, then content
38 character defaults to blank. Extra indicator attributes (beyond)
39 indicator length are treated as an error.
41 Reformat: delete trailing whitespace
45 MARC: fix non-ASCII characters for leader. This is to ensure we can
46 generate XML in UTF-8.
48 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
49 in one node with structure word.
53 yaz-json-parse: JSON output may be pretty printed by using option
56 Increase default value of max message for Z39.50 Init for GFS, ZOOM
57 and yaz-client. Old value was 1 MB. New value is 64 MB.
61 yaz-client: don't display bogus records from SRU servers. Some SRU servers
62 return more records than given by *maximumRecords*. Skipping those in
65 record_render: simplify buffer return handling and fix at least one bad
66 memory reference, that broke the test_embed_record sometimes.
68 Allow http://user:pass@host notation for yaz_url_exec.
70 zoomsh: allow shell command to be executed. Via the system(3) call.
72 yaz_poll: Allow num_fds == 0
74 yaz-client: fix bad encoding of "itemorder item". The itemorder
75 item <no> - command forgot to use length of encoded Item Request
76 package. Error present since YAZ 3.
78 yaz-ztest: fix bad usage of session handle. Bug was introduced when
79 result sets were saved (271a9c83).
81 SRU recordPacking: guess record packing in response rather than looking
82 at the recordPacking element which, OF COURSE, changed semantics in SRU
85 Decode SRU 2.0 responses. The official namespace for responses, according
86 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
87 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
88 nature.com's server, however, usee namespace
89 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
90 we are now using a glob-expr to match up the namespace. ZOOM C and
91 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
92 I can not find a single real example showing the "real" namespace in
93 the documentation from OASIS. The namespace for requests is different
94 from responses, but this is not added to YAZ yet, when we don't encode
99 zoom/record_render: add support for Base64 decoding fo MARC records
100 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
101 which will decode base64 + ISO2709 marc-8 encoded material from text node
104 --- 4.2.34 2012/06/07
106 Add missing definitions ZOOM_resultset_get_facet_field_by_index
107 and ZOOM_resultset_facets_names.
109 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
112 Change APDU dump printing to avoid long leading blanks. For levels 16
113 or larger the level is shown and the indentation is truncated but
114 recursed with modula 8. This makes it still reasonable easy to read
115 - even for nested BER dumps.
117 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
118 return 0 (incomplete package) in case where the BER package was
119 considered too nested (return value of -2).
121 dumpber: lines of level 15 are not indented further. Two spaces per
122 indentation; indentation 15 or more is indented to a fixed indentation
123 and augmented with a level=<no> indication.
125 zoomsh: increase max size of command+args
127 GFS: No limit in RPN buf size in CQL to RPN conversion.
129 --- 4.2.33 2012/05/09
131 New function for daemon utility, yaz_daemon_stop .
133 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
135 --- 4.2.32 2012/04/25
137 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
138 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
140 --- 4.2.31 2012/04/23
142 YAZ daemon utility relays SIGUSR1 to child process.
144 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
145 would result in en empty database list - which in turn would result in
146 encoding failure for search.
148 Fix reading beyond string in yaz_sort_spec.
150 --- 4.2.30 2012/04/11
152 Add two new SRU diagnostics:
153 236: Access to specified database denied
154 1015: Init/AC: Maximum number of simultaneous sessions for Userid
156 Document the very useful ZOOM-C option "apdulog".
158 CQL to RPN: term may be passed through verbatim. This is enabled with
159 truncation.cql . The assumption being that the term is already CQL.
161 --- 4.2.29 2012/03/20
163 record_conv: leader spec may be given for marc element.
164 The leader spec is given as attribute leaderspec for element marc.
165 For example to convert a MARC21 record from MARC-8 to UTF-8:
166 <marc inputformat="marc" outputformat="marc"
167 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
169 record_conv: allow user-XSLT params. For example:
170 <xslt stylesheet="MARC21slim2DC.xsl">
171 <param name="myparameter" value="myvalue"/>
172 <param name="otherparameter" value="othervalue"/>
175 record_conv: fix error handling for missing marc charsets.
177 CQL: fix extra terms in wrong order.
179 --- 4.2.28 2012/03/06
181 record_conv: modify new API for conversion types. The conversion types
182 may be passed in new functions yaz_record_conv_configure_t and
183 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
185 Avoid mixed statement/variable declare; fixes compilation with Visual
188 --- 4.2.27 2012/02/28
190 Add non-standard SRU diagnostic: 235: "Database does not exist".
191 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
192 Update SRU to Bib-1 diagnostic maps accordingly.
194 CCL: add two new diagnostics for unsupported masking. The new
195 diagnostics are: "Embedded truncation not supported" and
196 "Single charcacter mask not supported".
198 --- 4.2.26 2012/02/23
200 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
202 --- 4.2.25 2012/01/11
204 Build YAZ for Ubuntu Oneiric.
206 CCL: allow parantheses for proximity operands. For example CCL query
207 (a) % (b) is now allowed.
209 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
210 marked dead, rather then being destroyed. If not, the session memory is
211 being free'd before the search/scan handler is finished. Also destroy
212 'request' memory in request_release rather than in various places,
213 which resulted in leaks from time to time.
215 --- 4.2.24 2011/12/21
217 cql_sortby_to_sortkeys: honor sort prefix.
219 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
220 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
221 The rpn2cql family of functions now always returns quoted CQL terms.
223 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
225 --- 4.2.23 2011/12/15
227 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
228 sequence is treated as one. For example, &&a=b&&&c& is identical to
231 --- 4.2.22 2011/12/05
233 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
234 APDUs for a connection to a WRBUF.
236 --- 4.2.21 2011/11/23
238 Fix cql_sortby_to_sortkeys. Completely broken before.
240 Make CCL's @truncation work again.
242 --- 4.2.20 2011/11/09
244 New ZOOM connection setting: tproxy. It's like proxy, but does not
245 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
246 to set resolved address + port for a connection outside ZOOM itself.
248 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
250 --- 4.2.19 2011/11/07
252 Fix uninitialized variable in Solr spell support (could cause SEGV
253 for SRU response decoding).
255 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
256 back-end's addinfo through into the ZOOM response addinfo.
258 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
259 they are separated by a colon and a space rather than simply
262 --- 4.2.18 2011/10/28
264 Add support for Solr spell-checking/suggestions through ZOOM.
265 If a Solr target has been configured correctly for spelling-checking
266 and suggestions, these will now be returned on the ResultSet option
267 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
269 --- 4.2.17 2011/09/28
271 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
272 with a flag whether to substitute escape sequences or not.
274 --- 4.2.16 2011/09/22
276 Fix nmem_strsplit_escape to substitute escape char properly.
278 New option for zoomsh -e , which makes it abort on first error and
279 return process exit code to indicate success/failure.
281 YAZ options utility supports special option -- which makes all it treat
282 all following arguments as non-options.
284 --- 4.2.15 2011/09/16
286 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
287 searched if absolute filename is given.
289 Fix conv_xslt() error-reporting when stylesheet is not found.
290 (The value of fullpath is meaningless in this situation.)
292 --- 4.2.14 2011/09/07
294 Fix problem in CQL sort node creation: un-initialized memory.
296 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
297 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
298 CQL sortby depending on whether Type-1 or CQL is actually sent to the
301 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
302 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
304 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
305 will make it possible to use both single-character mask (#) and wildcard (?)
306 in CCL . Throw diagnostic for left truncation because that is not supported
309 --- 4.2.13 2011/09/01
311 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
312 cases using escapes (\-sequences) and masking.
314 PQF parse fix: A trailing backslash followed by end-of-string (\0)
315 would result in a read one byte beyond string.
317 rpn2ccl may use Z39.50 masking for terms (t=z).
319 ICU check fix. Don't include library -lCrun on Solaris, unless present.
321 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
322 not --cppflags (which seeems like an error in icu-config).
324 --- 4.2.12 2011/08/27 RPM package only
326 cql2ccl: fix conversion of terms: operator characters were not
329 --- 4.2.11 2011/08/25 RPM package only
331 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
332 CCL parser will map both # and ? to their regular expression
333 quivalents (. and .*).
335 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
336 of reserved CQL characters.
338 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
339 is, so that they are passed through.
341 --- 4.2.10 2011/08/24
343 ZOOM SRU mode: more aggressive re-connect.
345 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
346 made available as a utility function, declared in <yaz/logrpn.h>
348 rpn2cql_structure() supports proximity nodes (except that the Type-1
349 proximity node's "exclusion" binary is ignored, as there is no way to
350 express that in CQL). Fixes bug #4564.
354 Fix SEGV that could occur if set command of zoomsh was given without
355 value (2nd argument).
357 Fix SEGV that could occur if unsupported transport was given for
358 COMSTACK - say https (when SSL was unavailable).
360 Build yaz-url on Windows too.
364 New utility to get web content. Header is url.h. A command line tool
365 yaz-url is part of the distribution and packages.
367 Fixes for SSL COMSTACK (when gnutls is in use).
369 New functions yaz_base64{encode,decode}. Header is base64.h.
373 ZOOM C includes HTTP response buffer as additional info if it fails
374 to decode the SRU response.
376 Make wrbuf_json_puts available.
380 zoom: throw diagnostic for invalid value for option "sru". Before a
381 bad SRU request was sent.
383 Adding new utility wrbuf_vp_puts.
385 Add cclxmlconfig.obj to win/makefile. It was missing completely.
389 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
390 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
391 redirect was used at the same time.
393 MARC line mode decoding: be less picky about length given - first
394 5 digits of header that is.
396 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
398 Changes to decoding of SRU records: a record with recordPacking=xml is
399 modified with a new root element <yaz_record> if the recordData contains
400 multiple children elements. This is to make the record XML parseable
403 RPN to SOLR conversion: encode special characters.
405 Generic Frontend Server: fix uinitialized member, stepSize.
409 Fix a bug in SRU decoding of records.. The database records stored
410 had un-initialized memory, but it would only be seen with yaz_record_render
411 and type_spec="ext" .
413 Fix a bug in ccl_qual_dup introduced in 4.2.3.
417 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
421 Add new utilities to convert from CQL to CCL . These utilities have
422 prefix cql_to_ccl defined in cql.h.
424 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
425 lead to memory heap corruptions when ICU utilities were in use.
429 Make compilation work without Libxml2.
431 yaz-client: remove redundant blanks in display of searchResult-1 term
436 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
437 resulting CQL node (tree) in a new node CQL_NODE_SORT.
439 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
440 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
441 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
442 Note that the CQL sortby spec is only converted when the GFS is already
443 converting from CQL to RPN (cql2rpn element).
445 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
446 specify whether to collapse delimitors or not. The existing nmem_strsplit
447 do collapse (collapse parameter = 1).
449 Windows installer: For NSIS, set InstallDir depending on x86/x64.
451 Rename internal func yaz_use_attribute_create. While non-static, this
452 function is not declared in a public header.
456 Add -lCrun when linking with ICU on Solaris.
458 More quicks character set conversions for OPAC records.
462 fix problem with record_render: records were converted (character set
463 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
467 SRU: add methods for handling DADS SRU-proxy facets.
469 Separate OPAC record character set for ZOOM_record. yaz_record_render
470 allows a character set given as charset=from/opacfrom,to where 'from' is
471 the character set of a bibliographic record, 'opacfrom' is character set
472 of OPAC record and 'to' is the target character set.
476 yaz-client: show may XML format records. Command show followed by 'format'
477 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
480 src/stemmer.c: Avoid using unnamed union. It is not supported by some
483 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
486 Update yaz.spec to operate on both SLES11 / Centos 5.5.
488 RPM: Release includes 'indexdata' name. Use indexdata in release name so
489 this package can be distinguished from other vendors.
491 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
492 as determined by configure
494 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
496 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
497 returns no error and no record, the present request is considered
498 partial (only a subset of the records could be returned by backend), and
499 so it is appropriate to set Present Status to partial-4.
503 Move yaz-config man pages to section 1.
505 More documentation about SOLR.
507 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
508 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
509 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
510 peers on some Linux systems. However, in general that does not work
511 so YAZ can not rely on that to work. Debian changed behavior in this
512 respect from Debian lenny to Debian squeeze (still testing as of Oct
514 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
516 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
520 Fix yaz-config output: echo_source not set correctly by configure.
524 SOLR WebService support for yaz-client and ZOOM.
526 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
528 --- 4.0.12 2010/08/17
530 Z39.50 facet support. Facet specifications are passed for search in
531 other-information with ASN.1 as defined in facet.asn and OID
532 .10.1000.81.5 . Facets are expressed as an Attribute list as known
533 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
534 3 is limit (number of entries to get in response). yaz-ztest returns
535 dummy facets if a client asks for them.
537 --- 4.0.11 2010/07/09
539 CCL fixes: bug 2895 and bug 3539.
541 GR1-display: add comma in display - was removed by mistake in
544 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
546 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
548 --- 4.0.10 2010/06/18
550 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
551 result set from a connection. The result set will be on its own
552 thereafter; no operations on it will perform retrievals from a target.
553 Only cached copies are returned.
555 ZOOM C:fix case for HTTP servers responding with Connection:close.
556 Ensure that if there is a current task it is resumed (like fetching
557 more records in a result set) . Bug #3484.
559 PQF parser: use odr_atoi for Odr_int (not atoi)
561 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
562 values that contain any non-digits are treated as string attributes
563 (previously decoding only checked for leading character ([0-9]). PQF
564 encoding: attribute string values are not surrounded by double-quotes.
568 New utility for managing threads - thread_create.h.
570 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
571 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
572 but YAZ' implementation do.
574 Fixes for yaz_cond-functions on Windows 7.
576 DLL export more symbols.
578 zoomsh: show record do NOT render opac.
580 Remove *.la files from Debian and RPM packages.
584 Debian package libyaz-dev depends on libgnutls-dev again (was
585 removed in YAZ 4.0.6, but due to Libtool it is still needed
586 even though yaz-config do not list libgnutls libs).
588 ZOOM: Use only one WRBUF for returning string results for
589 ZOOM_resultset. Reduces memory usage for ZOOM in general.
591 ZOOM: ZOOM_connection do not use a shared pointer to
592 ZOOM_resultset after ZOOM_resultset is destructed by
593 user. Reverts to YAZ 4.0.4 behavior.
597 record-conv: fix problem with at least one XSL conversion -
598 due to probably incorrect usage of XML XSL documents.
602 Fix yaz-config for static mode and the use of SSL (gnutls).
606 Forward decl timeval struct in mutex.h and gettimeofday.h.
608 yaz-config: fix 'static' mode linking.
612 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
613 are wrappers for pthreads or Windows. For Windows these are put in
614 a separate DLL: yaz_cond4.
616 libyaz.la (whole source) is compiled with thread. If thread support
617 is enabled enabled, all source of YAZ is compiled with treading support.
618 This allows core utilities such as yaz_log to use thread facilities.
619 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
620 thread utilities. This commit moves mutex utilities (mutex.c) from
621 libyaz_server.la to libyaz.la.
623 yaz-json-parse displays leading text until error.
627 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
628 patch from Giannis Kosmas.
630 SRU: no longer URL encode SRU database. The URL for an SRU server is
631 a URL and such is alreeady encoded - at least when given with leading
632 http:// or https://. This reverts behavior to YAZ 3.0.50.
634 Support for new MARC XML notation TurboMARC which like MARCXML is a
635 complete representation of MARC/ISO2709.. This one, however, is more
636 compact and allows for faster processing with XSLT. TurboMARC can be
637 used in the marcdisp.h API, from the yaz-marcdump utility and from
640 yaz-ztest can be configured - via the database - to perform certain
641 delays when it performs operations search, present and single record
642 fetch. This allows testers to make yaz-ztest act as a real or even slow
643 Z39.50 server. Refer to the yaz-ztest man pages for details.
647 wrbuf_destroy allows NULL WRBUF passed to it.
649 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
651 Add ZOOM_connection_close.
653 No fixed size buffers for ZOOM shell - bug #3257.
655 tstodr: make it work on s390 platform.
657 New icu iterator-functions. The new icu_iter-functions makes it possible
658 to use ICU chains from many threads.
660 yaz-client: better syntax check for show command.
664 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
667 New simple local-file XML include facility which allows file glob-patterns.
668 Refer to yaz/xml_include.h.
670 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
673 ZOOM_record_get supports new parameter "format" which makes it format XML
676 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
677 JSONText in ECMA-262) is JSONValue, not JSONObject.
681 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
682 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
684 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
685 POSIX/Unix builds .so with major version 4.
687 Remove old LOG_-defines from log.h. They have been obsolete and
688 undefined by default for the last 5 years.
690 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
692 GFS: Remove socket (int *fd) from search_rr handler. The socket
693 descriptor ptr is a facility that allowed a search handler to supply
694 a socket which would serve as a callback - when search was complete.
695 This facility has now been in use for years.
697 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
698 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
699 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
700 returns 'const char *' rather than 'char *. The returned string is
701 read-only and should not be modified by applications. COMSTACK cs_close is
702 now a void function - it no longer returns int. No applications check for
703 the value and the implementations has always returned 0.
705 ZOOM: use size_t for scan hit counts and str size. Functions
706 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
707 occ (hit count) and len (string length) are now of type size_t pointer
708 rather than int pointer. This is to be able to represent large hit counts
709 and to also just to use the proper type for string length (strlen result).
711 New JSON parser. Refer to include/yaz/json.h .
713 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
714 Used to be int in some cases. Many wrbuf_-functions used to return an int
715 indicating some length.. These return values were never used. And so they
718 ODR: odr_malloc, odr_total now takes size_t for size.
720 clone_z_type: fix leak; occurred for encoding failures.
722 --- 3.0.52 2009/12/03
724 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
725 bug was introduced in 3.0.51.
727 --- 3.0.51 2009/12/02
729 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
731 tcpip comstack: fix leak for getaddrinfo.
733 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
734 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
735 Decoding of SRU "path" database is performed by private function
736 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
737 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
739 yaz-client: honor base command for SRU. Change when database setting
740 is applied for SRU and ensure it is kept when a connection is reset.
741 Change also the way errors are displayed or SRU (decoding of packages).
743 --- 3.0.50 2009/11/02
745 Add support for extra request / response data for SRU codecs and GFS.
746 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
747 for extra data response buffer and length. For the GFS, both request
748 and response data (XML) is carried in extra_args and extra_response_data
749 for the search handler. Patch by Ko van der Sloot.
751 ZOOM: For queries that cannot be converted to the specified rpnCharset,
752 ZOOM now returns a diagnostic on the client-side ('invalid query' /
753 10010). This fixes bug #2113.
755 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
756 cmdfile included a 'quit' command that would result in a memory violation.
758 --- 3.0.49 2009/10/01
760 Make a number of functions defined in xmlquery.c static. These have
761 never been declared in a public header file (yaz/xmlquery.h) and was
762 made public by mistake.
764 Improve speed of character conversions (iconv utilities). This makes
765 conversions from MARC-8 faster.
767 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
768 unless type desired is "raw". This will prevent type "xml" from
769 returning ISO2709 .. Which obviously can not be XML parsed.
771 Fix memory leak in ZOOM that would occur if option apdulog was used
772 on a re-used connection.
774 Frontend server logs HTTP requests.
776 Frontend server now sends Z39.50 close when it times out (sesssion has
777 been idle for too long). Versions 2.0.30 and earlier also sent close.
778 But due to a mistake this was disabled in all versions after that, i.e.
779 the server would just close the socket immediately.
781 yaz-client emits a better message when receiving an unrecognised
782 userInformationField.
784 Skip zero-length subfields when decoding ISO2709. This rare case happens
785 if a record has two FS characters in a sequence. Without this patch
786 there would be a reference beyond char array in using_code_len fragments
789 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
791 --- 3.0.48 2009/08/28
793 The show command offered by the zoomsh command now takes a 3d optional
794 parameter type which is what is passed to ZOOM_record. If the type
795 argument is omitted, "render" is used.
797 RPN to CQL conv may use USE string attributes (bug #2978).
799 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
801 --- 3.0.47 2009/07/08
803 Function yaz_xml2query allows a diagnostic element in the PQF XML
804 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
805 code and additional info respectively.
807 The BER BOOLEAN is now the integral type Odr_bool which still happens
808 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
809 typedef'd to Odr_int. This is still an integral 'int', but it may be
810 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
811 ASN-1 compiler as well as programs has been updated to use the new types.
813 --- 3.0.46 2009/06/08
815 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
816 only the bibliographic record was rendered. For type=opac, an OPAC
817 record is only returned if it is present.
819 iconv: small fix for encoding of advancegreek.
821 yaz-client: avoid double display of SRU/SRW records (bug #2798).
823 yaz-client: option auto_reconnect=on really reconnects.
825 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
827 server: avoid null ptr ref for for yaz_poll errors.
829 build: fix RPM build for RHEL 5.3.
831 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
833 --- 3.0.45 2009/03/31
835 Fixed bug #2709: TCP connect returns Invalid argument.
837 Fixed compilation for mingw.
839 Honor charset for raw records (ZOOM_record_get).
841 Fixed use of errno for threaded mode that was seen on Solaris 10.
843 Fixed argument passing with blanks in value for Windows Service.
845 Disable YAZ' own log rotate by default (no 1 GB limit).
846 The variable l_max_size which specifies the log file limit is set to 0
847 (DISABLED): This is due to the fact that YAZ is most often deployed using
848 logrotate. Also YAZ can not perform log rotate because of unsufficient
849 permissions (setuid).
851 --- 3.0.44 2009/02/17
853 List supported encodings in man page for yaz-iconv.
855 Fixed missing SSL libs for --libs output
857 Re-established OID record syntax application-xml. Nobody should use it
858 but we don't want to change soname because of this symbol being absent.
860 --- 3.0.42 2009/02/02
862 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
864 Added member named_result_sets for init handler struct for the GFS. This
865 allows a server to disable named result sets.
867 Removed OID record syntax application-xml.
869 Added support for rule-based transliterator for ICU wrapper of YAZ.
871 Fixed bug #1902: yaz-icu XML output.
873 Make YAZ checks Emacs friendly.
875 BITSTRING value shows value. Bug #2346.
877 ISO2709 decoding: skip control characters from indicator data.
879 Omit sort key by default in yaz-icu's output.
881 Allow combined single char options (again) for YAZ' options function.
883 Utility yaz-marcdump got option to display YAZ version (-V).
885 Allow YAZ to use ICU 3.4.
887 Added new ICU test case which illustrates removal of diacritics.
889 --- 3.0.41 2008/12/29
891 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
893 --- 3.0.40 2008/12/29
895 For configure, using option --without-xml2 also disables Libxslt/Libexslt
898 Fixed bug #2352: yaz-marcdump crashes for certain record.
900 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
902 Added support for Danmarc2 to UTF-8 conversion.
904 Added support for ISO5426 to UTF-8 conversion.
906 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
907 implementation version.
909 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
911 --- 3.0.38 2008/11/10
913 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
914 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
916 ZOOM C now interprets databaseName option for ZOOM connection as path
919 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
921 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
923 Dummy Libxml2 types no longer defined in headers of YAZ'.
925 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
928 --- 3.0.36 2008/09/26
930 Various ODR chapter fixes.
932 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
934 Added missing source for Windows compilation, mutex.c.
936 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
938 For SRU connections in ZOOM all records up to "count" are now fetched.
940 Fixed crash in generic frontend server (and yaz-ztest) which occurred
941 in Windows due to bad error handling for Libxml2.
943 Added facility for sending arbitrary records (ASN.1 any) using
944 ZOOM C's Extended service update. Patch by Sam Reynolds.
946 New options for ZOOM C's connection, logapdu which makes ZOOM log
949 --- 3.0.34 2008/06/18
951 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
953 --- 3.0.32 2008/06/12
955 Fixed memory violation that could occur when decoding UTF-8. This bug
956 was only present in 3.0.30 of YAZ.
958 --- 3.0.30 2008/06/06
960 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
961 GNU TLS is used by default (if found).
963 yaz-ztest returns OPAC records if a client asks for OPAC.
965 Improved speed of MARC-8 encoding.
967 Added support for lossy and loss-less MARC-8 encoding.
969 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
971 Added new Windows Service wrapper (sc).
973 yaz-client's itemorder command may now send a file.
975 Fixed yaz-marcdump to allow the use of NS prefix for record element.
977 Added new function yaz_log_xml_errors.
979 Allow (but warn) unknown XML attributes in MARCXML parsing.
981 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
983 The UTF-8 to MARC-8 conversion now uses a different set of characters
984 for Greek symbols. Bug #2120.
986 --- 3.0.26 2008/02/21
988 Added yaz_daemon (daemon.h).
990 Fixed bug #2068: pkg-config trouble
992 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
994 --- 3.0.24 2008/01/28
996 Document --with-xml2 option.
998 Added OPAC XML XSD (etc/opacxml.xsd).
1000 Allow glob mask for name attribute in retrieval element for the
1001 generic frontend server's retrieval facility.
1003 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1004 except POLLIN/POLLOUT.
1006 Fixed error handling in cs_listen. Bug #2037.
1008 --- 3.0.22 2008/01/20
1010 Fixed version in yaz/yaz-version.h.
1012 Fixed bug #2027: Crash when closing connection.
1014 Changed configure so that ICU support is only enabled if only ICU
1015 and Libxml2 is available (because the ICU chain is XML based).
1017 --- 3.0.20 2008/01/15
1019 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1020 is built. Only this DLL depends on the ICU runtime.
1022 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1023 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1025 Changed license of CCL module to 'Revised BSD'. After consultation with
1026 remaining members of the original EUROPAGATE consortium, we are re-issuing
1027 the CCL module without a separate license. The software was developed by
1028 Index Data as part of a research project. The special license was included
1029 to help feed usage information back to the project consortium to support
1030 project evaluation. At this time, the project consortium has long-since
1031 disbanded, and the majority of the original principals have retired. At the
1032 same time, we have significantly modified the software during the following
1033 years, to the point where very practically no original code remains. To
1034 simplify re-use of the software, we have contacted those members of the
1035 consortium who could be reached, and agreed to re-issue the module as a
1036 proper part of the YAZ package.
1038 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1040 CQL closer to being version 1.2 compliant. CQL also allows free-form
1041 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1044 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1045 bug could make Extended services handling crash in the ZOOM layer. This
1046 bug was only present in YAZ 3.0.18.
1048 --- 3.0.18 2007/12/19
1050 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1053 yaz-marcdump reads and writes collection wrapped records.
1055 Handle OPAC for record conversion module.
1057 Fixes for ICU wrapper.
1059 Allow ICU libs to be controlled with --with-icu .
1061 --- 3.0.16 2007/11/12
1063 Added yaz_poll which is a wrapper for select/poll. When poll is available
1064 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1065 sockets to be in use.
1067 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1068 functionality through an XML based configuration (ICU chain). This system
1069 is useful for search facilities such as Pazpar2 and Zebra that needs to
1070 perform tokenization of indexed material. The ICU code in a separate
1071 library libyaz3_icu.a.
1073 Added HTTP tunnel facility for COMSTACK, bug #1752.
1074 This is a facility that allows a Web proxy, such as squid, to tunnel
1075 Z39.50 traffic. This facility is "transparent" to must applications
1076 using YAZ. It's enabled by using pseudo transport connect: followed by
1077 the proxy address, followed by command, then follwed by he regular
1078 "virtual" addresss. For example,
1079 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1081 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1083 --- 3.0.14 2007/09/21
1085 Fixed bad memory reference in ZOOM_record - cuased by member not being
1086 initialized. This was a problem only in YAZ 3.0.12.
1088 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1089 fields were not removed.
1091 Changed the way C code is generated from codetables.xml. Made a MARC-8
1092 conversion trie for each characterSet section rather than codeTable.
1093 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1094 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1096 --- 3.0.12 2007/09/12
1098 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1099 from ZOOM_record_error).
1101 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1103 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1105 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1107 Better SRW-to-Bib-1 diagnostic mapping.
1109 ZOOM C and yaz-client announces SRU version 1.2 by default.
1111 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1114 Fixed in yaz_sru_decode to allow other version than 1.1.
1116 --- 3.0.10 2007/08/22
1118 Added support for SRU scan for ZOOM.
1120 Added support for the use of the older versions or Extended Service
1121 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1122 set to the version , 1=first, 2=second, 3=third. The third version is
1123 what ZOOM C has used so far. And that, obviously, is the default.
1125 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1126 therefore in Zebra and in SimpleServer-based applications). The new
1127 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1128 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1129 which is passed into the back-end search callback function.
1131 Added support for HTTP Basic authentication in clients: the SRU/W
1132 codec encodes the username/password elements of the PDU structure
1133 appropriately, and these may be set using the "user" and "password"
1134 options in ZOOM-C applications (the same options that are used for
1135 Z39.50 authentication).
1137 --- 3.0.8 2007/06/25
1139 Fixed bug #1208: SSL appears to be broken in ZOOM.
1141 Fixed bug #1206: Libxml2 include path weirdness.
1143 Added oid_name_to_dotstring.
1145 Allow elementSetName to be specified for ZOOM C record update.
1147 Allow waitAction to be specified for ZOOM C based for Extended Services.
1149 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1150 syntax OID. Bug introduced in YAZ 3 series.
1152 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1154 --- 3.0.6 2007/06/06
1156 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1157 directory. yaz-client now reads commands from file given by option -f
1158 if specified; then tries to read .yazclientrc in current directory.
1159 Failing that, it reads .yazclientrc from user's home directory.
1161 Added support for correlationInfo Note and ID for Record Update via
1164 Added yaz-client command querycharset which specifies character set for
1165 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1166 (termListAndStartPoint).
1168 Charset ISO5428:1984 is an alias for ISO5428-1984.
1170 Implemented a way to perform scan in a result set using Z39.50. This
1171 is achieved by attaching the result set name in the characterInfo
1172 (type InternationalString) of OtherInformation in the Scan Request PDU.
1173 The result set is identified in the otherinformation by the new OID:
1174 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1175 This allows for scan in result set and faceted search . Zebra did some
1176 of this in the APT term using attribute type 8 and value being result
1177 set. Using the OtherInformation approach for this is cleaner and easier
1178 to work with in proxies and the like. This facility can be used in
1179 yaz-client using new command setscan which takes a result set as first
1180 argument, start position (APT) as second.
1182 Changed decoding of SRU XML packed records to deal with servers that
1183 have recordData with XML data with multiple root nodes. Also make
1184 comparison for recordPacking case insensitive. Again, one server
1185 returns "XML" where others return "xml".
1187 For SRU responses allow Content-Type application/xml as well as text/xml.
1189 --- 3.0.4 2007/05/21
1191 Fixed bug in character set conversion of BER strings. Bug introduced
1194 --- 3.0.2 2007/05/08
1196 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1198 For OID class, use oid_class consistently.
1200 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1203 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1204 character set for bibliographic information interchange". By Giannis Kosmas.
1206 Added documentation on new OID API.
1208 --- 3.0.0 2007/05/02
1210 Changes to generic frontend server interface: added new member
1211 'query_charset' for bend_initrequest structure. A backend init handler
1212 should set this member to its native character set for query terms.
1213 When defined, the frontend server logic will announce this character set
1214 to a client if the negotiationModel bit is set by the client. All server
1215 implementors are encouraged to specify this. If a backend server does not
1216 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1218 Added CCL utility to remove terms (stop words) from resulting RPN
1219 tree. This is handled by functions with prefix ccl_stop_words_ .
1221 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1222 terms in RPN queries.
1224 Clean-up the CCL API. Moved some internal structures from ccl.h to
1225 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1226 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1227 This is replaced by ccl_parser_find_str which takes a string instead.
1229 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1230 libyaz.la is the core of YAZ except the generic frontend server and
1231 does not depend on POSIX threads anymore. libyaz_server.la is the
1232 generic frontend server facilities and uses POSIX thread functionality
1233 if available. The libyaz.la no longer depends on POSIX threads because
1234 the number of global structures is limited. NMEM no longer re-uses blocks
1235 between threads ; it simply free's memory immediately but allocates in
1236 "large" chunks as usual. We don't expect any performance penalties
1237 because of this. The yaz_log system is still using a global log_level so
1238 caution must be taken when modifying it with yaz_log_init_.. +
1239 yaz_log_mask_str. This, however, should not cause any trouble because
1240 these functions are called during initialization of application code
1241 anyway. `yaz-config --libs server` returns libs for server applications;
1242 `yaz-config --libs` returns libs for non-server applications.
1244 New OID database - with public definitions in oid_db.h. Removed old OID
1245 database including the head oid.h and definitions such as enum oid_value
1246 and struct oident. The new OID database uses the same string names as
1247 before but the 'protocol' is gone. There are now only two representations
1248 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1249 converts from string to OID; functions with prefix yaz_oid_to_string
1250 converts the other way.
1252 Change to emit_term() in CQL-to-PQF query translation: when a term has
1253 the /regexp relation modifier, do not process it for leading and
1254 trailing "^" and "*", which have quite different meanings in regular
1257 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1258 write handlers no longer carries a 'last' parameter. This will make
1259 yaz_iconv flush "less" characters. A flush is performed by call to
1260 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1262 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1263 removed, because function yaz_query_to_wrbuf does the same.
1265 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1266 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1268 Deprecated MARC utility functions removed.
1270 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1273 Branch split: YAZ_2_1_55_branch
1275 --- 2.1.54 2007/03/16
1277 Fix to ZOOM-C so that transparent reconnection is properly handled on
1278 connections that are in asynchronous mode.
1280 Fixed compilation on OpenBSD 4.0.
1282 Large strings in GRS-1 records are now properly displayed in yaz-client.
1284 Added character conversion support for "advancegreek"; based on patch from
1287 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1288 sequence is met. Before the error was not set so it would be unknown.
1290 Adjust yaz-marcdump MARC reader so that it skips until record separator
1293 --- 2.1.52 2007/03/07
1295 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1296 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1297 fd_set structure used as a bitmask for the FDs to be selected on.
1299 Using ACX_PTHREAD macro to check for POSIX threads.
1301 Fixed have-vsnprintf check.
1303 --- 2.1.50 2007/02/23
1305 Fixes for configure on BSD. Bug #900.
1307 Added snprintf/vsnprintf wrappers for systems that don't have
1308 limits (heavens forbid).
1310 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1311 created before all previous tasks were completed and removed from the
1312 task queue, the new task could be removed by a mistake.
1314 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1316 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1318 Fixed bug #832: Problem with MARC/charset in yaz-client.
1320 Fixed bug #668: save command line history for yaz-client.
1322 Fixed bug #830: pkg-config support.
1324 --- 2.1.48 2007/01/23
1326 Extended ZOOM result set options with two options that may be read by
1327 a client: resultSetStatus and presentStatus with values as specified for
1329 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1331 Fixed bug #827: Using SSL fails on Debian etch.
1333 Fixed bug #826: Weird looking chars for set of MARC records.
1335 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1336 that is treated as an ItemOrder with itemRequest being an XML document
1337 external. The value of "doc" is the content.
1339 Extended the GFS search facility. New member of bend_search_rr
1340 'estimated_hit_count' signals that hits is known to be an estmate
1341 (higher or lower than real hit count). New member 'partial_resultset'
1342 signals that the search was partial (hit count is lower or equal than
1343 real hit count). For Z39.50, the information is stored in resultSetStatus
1344 member of SearchResponse APDU. For SRU, the information is signalled
1345 via SRU diagnostic 59: "Result set created with valid partial results
1348 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1350 --- 2.1.46 2007/01/13
1352 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1354 Added ZOOM_connection_peek_event.
1356 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1357 the following new functions:
1358 ZOOM_event_nonblock, ZOOM_connection_process,
1359 ZOOM_connection_get_{socket,mask,timeout},
1360 ZOOM_connection_fire_event_{timeout,socket}.
1361 The existing blocking event handler, ZOOM_event, is a wrapper for the
1362 + blocking ZOOM_event_sys_{poll,select}.
1364 Implemented function ccl_xml_config which parses XML version of CCL
1365 configuration (bug #798).
1367 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1369 Added timings utility (yaz/timing.h)
1371 --- 2.1.44 2007/01/03
1373 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1376 Fixed bug #779: Rotation of apdu.log fails.
1378 Fixed for character set conversions:
1379 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1380 Honor G1 set in MARC-8 decoding.
1382 --- 2.1.42 2006/12/17
1384 Fixed bug #775: char conversion does not handle Alternative UTF-8
1387 Implemented function yaz_marc_read_line which parses MARC line format
1388 records. There is a wealth of formats out there. So far, this function
1389 reads line records produced by yaz_marc_write_line.
1391 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1392 more generic and easier to remember(!) options: -i format and -o format
1393 which specifies input format and output format respectively - where
1394 format is one of "marc", "marcxml", "line", "marcxchange".
1396 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1397 does not print anything except warnings for records.
1399 For yaz-marcdump, added support for MARC split into files (-s) with a given
1402 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1403 spec, at http://www.loc.gov/standards/sru/record-update/
1404 This has changed the binary layout of the following structs:
1405 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1406 bend_update_rr . Patch by Ko van der Sloot.
1408 Added GFS utility function bend_assoc_is_alive which returns 1 if
1409 association is still alive (client is connected); 0 otherwise (client
1410 closed connection). This allows busy servers to stop working for
1413 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1414 been a separate piece of software. This version of ziffy has been modified
1415 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1417 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1419 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1420 Client code may now interrogate options such as "init_opt_sort" to
1421 find out whether the server claims to support various options.
1423 --- 2.1.40 2006/11/27
1425 Added utilities yaz_{set,get}_esn to set/get element set name from
1428 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1429 of YAZ and has been so since YAZ 2.1.10.
1431 Implemented ZOOM_record_error which returns error information for
1432 record (surrogate diagnostic).
1434 --- 2.1.38 2006/10/31
1436 Updates for SRU Update by Ko van der Sloot:
1437 1. Changed name from "operation" to "action"
1438 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1439 versions in the code, marked as 'backward compatible'.
1440 3. Added diagnostics for SRU Update.
1442 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1444 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1446 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1448 For GFS, fixed problem with SRU diagnostic 'First record position out of
1449 range' being issued for 0 hits.
1451 zoomtst10 part of Windows Build.
1453 --- 2.1.36 2006/10/13
1455 Implemented yaz_filepath_comp which splits a path into file path
1456 components (required by Zebra 2.0.3+).
1458 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1459 BSD inspired license until now so this should not have any real impact on
1460 anybody. See http://www.opensource.org/licenses/bsd-license.php
1462 Fixed bug #687: Missing log lines.
1464 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1467 Fixed bug #689: SRU diagnostics to be added.
1469 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1470 whether a connection is idle (no more work do do).
1472 --- 2.1.34 2006/10/04
1474 Change type of optval from long to int for invocation of setsockopt with
1475 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1477 Added support for specifying the max log file size for the Generic
1478 Frontend Server. The size is given with option -r.
1480 --- 2.1.32 2006/09/21
1482 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1484 --- 2.1.30 2006/09/17
1486 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1489 Fixed bug in Generic Frontend Server that could cause a server to stop
1490 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1492 For the generic frontend server, the maximum record size is used as maximum
1493 size of incoming packages (SRU + Z39.50). The value until was previously
1494 only used in Z39.50 Init negotiation and, later, in a session controlled
1495 sizes of records returned. This is controlled using -k option. It can be
1496 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1498 --- 2.1.28 2006/09/04
1500 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1503 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1505 New option for yaz-marcdump -lpos=value which allows setting a portion
1506 of MARC header to a certain value.
1508 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1510 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1511 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1513 --- 2.1.26 2006/08/15
1515 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1518 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1520 --- 2.1.24 2006/08/08
1522 Fixed MARC ISO2709 encoding routines to deal with character set
1525 Minor changes to GFS logging. Database included in search request log
1528 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1529 cached/multiple records.
1531 Shared libraries are built by default on Unix+configure.
1533 Changed cql2pqf transformation to use a different evaluation order. The
1534 new order is: always, relation, structure, position, truncation, index
1535 and relationModifier. Old order was: always, relation, relationModifier,
1536 structure, index, position, truncation. Note that the the latter ones
1537 override former ones for identical attributes.. The new scheme means that
1538 it is possible to override any existing attribute with a relationModifier.
1539 And also that it is possible to override everything for the index rule
1540 (except the ones listed in relationModifier). No order is perfect but this
1541 one, we believe, covers more real cases.. The "always" should have been
1542 called "default", since the attributes there can be overridden with all
1545 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1546 compilation phase, but also for yaz-config --cflags output. This allows
1547 us to have public headers with Libxml2 stuff in them . It should also,
1548 eventually, make Libxml2 checks redundant in packages using YAZ, such
1551 --- 2.1.22 2006/06/15
1553 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1554 stored in uri, message and details.. Previously diagnostics were stored
1555 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1556 compatibility.. but he's probably the only one affected, so.
1558 Added support for CCL, compiled on the client side, in ZOOM-C. This
1559 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1560 input; the resulting query objects can be used for for searching with
1561 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1563 YAZ' configure searches for OpenSSL by default.
1565 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1566 SL_CTX_use_certificate_file. See
1567 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1568 for more info. Thanks to Ko van der Sloot.
1570 --- 2.1.20 2006/06/02
1572 Bug #600: SRU GET, POST support for yaz-client. Introduced
1573 command 'sru' which selects method SOAP/GET/POST.
1575 Allow missingValueAction to be specified for the sortspec string -
1576 function yaz_sort_spec. By default, the missing value action is null.
1577 Use ! to specify "abort". Use = followed by stringvalue to specify default
1580 Ensured that Present-handler (if defined) is called in GFS before any call to
1581 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1582 searchRetrieve requests.
1584 Documentation for YAZ is now based on the Docbook XML/XSLT using
1585 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1586 is no longer depending on jade/openjade or docbook-to-man scripts.
1587 PDF is no longer part of the distribution - but can optionally be
1588 made using DSSSL/jadetex or FOP.
1590 Added retrieval handling support in Generic Frontend Server to support
1591 conversion between MARC/XML as well as XSLTtransforms. See
1592 etc/yazgfs.xml for an example.
1594 Added Authentication support to Generic Frontend Server in SRU
1595 mode. Authentication using HTTP Basic is supported, as is the use
1596 of 'x-username' and 'x-password' parameters in the request itself.
1598 Added support for a new character set MARC8s identical to MARC8 except
1599 that it converts combined characters to single Unicode characters in the
1600 Latin-1 range (when possible).
1602 --- 2.1.18 2006/04/24
1604 ASN.1 compiler 0.4: generates brief Doxygen file header for
1605 generated .h/.c files.
1607 Utility yaz_iconv now supports conversion to MARC-8.
1609 New facilities for the MARC module. The reading - and writing of
1610 content are separate methods for the yaz_marc_t handle. The following
1611 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1612 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1613 format). Write functions have prefix yaz_marc_write_.. The existing
1614 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1615 available. Removed support for OAI-MARC and simplexml (not the
1616 simplexml from PHP5).
1618 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1619 to be returned for this connection.
1621 --- 2.1.16 2006/03/31
1623 Allow multiple languages and charsets to be specified with
1624 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1625 negcharset iso-8859-1,utf-8
1627 Translation of proximity nodes from CQL into PQF now works.
1629 Moved to automake 1.8, 1.9.
1631 Added function yaz_log_set_handler which allows a log handler to be
1632 installed. This handler will be called for all log messages. Output
1633 to file is also produced; but that can be disabled by passing NULL
1634 fname to yaz_log_init_file.
1636 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1638 For SRW (including GFS), accept application/soap+xml as content-type
1641 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1642 produces NO stylesheet reference even if a default stylesheet is specified
1645 --- 2.1.14 2006/03/14
1647 Updated Windows package to include yazd.dll + yazd.lib for the
1648 Development component.
1650 If the environment variable YAZ_LOG is set, then it is used as a
1651 string indicating the default level of logging to use if not
1652 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1653 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1654 used as before. So, for example, to omit warnings from YAZ logging,
1655 export YAZ_LOG=-warn
1657 cql_transform() now map structure and other attributes before indexes,
1658 so that index-specific structures and other attributes can override
1659 defaults. So now a combination of mapping specifications such as:
1661 index.dc.date = 1=date-modified 4=5
1662 does the right thing.
1664 cql_transform() now also respects the "always" mapping specification,
1665 which establishes an initial set of attributes to be used for all
1666 terms except where overridden by more specific attributes associated
1667 with the index, relation or modifier.
1669 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1670 which mode to use; one of "post", "get" or "soap" (SRW, default).
1672 Fixes for yaz_iconv routines: changed trie-based character set conversions
1673 to use only non-negative values for bit fields due to Sun's C compiler not
1674 supporting negative values.
1676 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1677 sequences where not read correctly. Fix by Rustam Usmanov.
1679 Updated win/makefile to use options, settings which makes things
1680 compile with VS C 2005.
1682 --- 2.1.12 2006/02/01
1684 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1686 In ZOOM socket code, use select instead of poll on MacOSX.
1688 ZOOM-C now support client-side compilation of CQL into RPN that is
1689 sent to the server, enabling CQL to be used against all Z39.50
1690 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1691 ZOOM_query object, and submit it using ZOOM_connection_search().
1692 The CQL-to-RPN translation uses a configuration file, the name of
1693 which must be specified in the Connection's "cqlfile" option.
1695 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1696 function, which takes as its start-term parameter a ZOOM_query object
1697 (which may have had either CQL or RPN set into it).
1700 --- 2.1.10 2005/11/29
1702 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1703 GFS to support this as well. Backend handler, bend_srw_update, does the
1704 update work. Code contributed by Ko van der Sloot.
1706 Allow retrieval of Search Result-1 information in ZOOM by the use of
1707 options that are attached to a result set. ZOOM documentation updated
1710 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1711 UTF-8 conversion. Patch by Raj Patel.
1713 Added option -m to GFS to control formatting of timestamps in log file.
1715 Added 'exit' as synonym for 'quit' in yaz-client
1717 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1718 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1719 for the new members. Patch by Ko van der Sloot.
1721 Added support for SRU POST. It is supported for content-type
1722 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1724 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1725 Instead make the library libyaz.la multi-threaded. Threading as a whole
1726 can still be disabled by configure option --disable-threads. Previosly,
1727 with older GLIBCs there were problems with MT libs under Apache. This
1728 has now been fixed a long time ago.
1730 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1733 CQL module modified to be case insensitive for relations/indexes/operations.
1735 Fixed bug in CQL transform code: incorrect value relationModifieder
1738 Added 'show all' command for yaz-client which retrieves all results
1741 Added new yaz-client, xmles, which takes a (private) OID and
1742 a document to be sent as an extended service request.
1744 Describe new yaz-client commands wait_response and set_auto_wait.
1746 Increase TCP/IP listener backlog from 3 (which I am guessing was
1747 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1748 that the socket will queue as many incoming connections as it's able
1749 to handle ongoing connections. In other words, it will never now
1750 refuse a connection that it would be able to handle merely because
1751 it's not got around to accepting() enough of the pending connections
1752 yet. This is the behaviour anyway under Linux, where the listen()
1753 argument is ignored; but not under BSD and on systems such as
1754 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1755 YAZ-based servers should now be uniform across operating systems in
1758 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1759 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1760 This allows yaz-marcdump to read large MARC batches (>2 GB).
1762 Modified all YAZ source files - except the source which is auto-generated
1763 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1766 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1767 corresponding to the existing *_setl() function. These allow option
1768 values containing arbitrary valuues.
1770 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1771 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1772 except that it returns an indicator of whether or not the sort
1773 criterion was accepted (0 for OK, -1 for invalid).
1775 --- 2.1.8 2005/06/07
1777 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1778 MARC output rather than returning "new" buffer.
1780 yaz-client warns about unknown init options.
1782 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1784 --- 2.1.6 2005/05/24
1786 Added support for SRW sort in Generic Frontend Server. Patch
1787 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1788 sortKeys - or NULL if none is provided.
1790 Fixed bug #307: It was impossible to specify indefinite/no timeout
1791 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1794 Added support for multiple languages and charsets to be specified in
1795 ZOOM. Each charset/language is separated by a blank. If negotiation is
1796 in effect in init-response, Option
1797 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1798 Code based on patch by Vasiliy Osadchuk.
1800 Fixed bug #306: infinite recursion that occurred when calling
1801 yaz_log_level_init as the first call (before other log level or
1804 Fixed bug in scan handling in front end server: if preferred-Position-In-
1805 Response was non-present, a NULL pointer referece was performed.
1807 --- 2.1.4 2005/04/26
1809 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1810 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1811 now defined for all those error codes. So instead of putting 109 in
1812 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1813 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1815 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1818 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1820 Program yaz-client now exits and produces an error message if multiple
1821 Z39.50 servers are specified on the command line (none or one allowed
1824 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1827 --- 2.1.2 2005/03/16
1829 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1831 Fixed bug #272: Preserve spacing for CCL terms.
1833 --- 2.1.0 2005/03/14
1835 Added support for virtual hosts and multiple backend servers for
1836 the YAZ frontend server. The configution is XML based and
1837 support specificition of CQL to RPN mappings and explain information.
1838 See section "Virtual Hosts" in the YAZ manual.
1840 Extended OPAC display utility. OPAC display utility renders
1841 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1842 to supplement yaz_marc_decode_wrbuf.
1844 Fixed a bug in MARC decoder that could caused it to crash for some
1845 invalid MARC records. More diagnostics and warnings where added in
1846 XML output (warnings, etc are stored in comments).
1848 --- 2.0.34 2005/02/08
1850 Fixes for UNIX domain sockets. Bug #261.
1852 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1854 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1855 Added yaz_marc_subfield_str which defines subfield lead string which is
1856 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1857 yaz_marc_endline_str which defines end of fields string used in
1858 YAZ_MARC_LINE format. Default string is newline.
1860 Experimental support for MarcXChange. This format can be produced
1861 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1862 http://www.bs.dk/standards/MarcXchange.xsd
1864 Added yaz-client commands scansize that sets maximum number of
1865 entries to be returned by scan.
1867 --- 2.0.32 2005/01/11
1869 Added support for SRW scan in yaz-client and Generic Frontend Server.
1871 * Added whereInList member to SRW Scan Term.
1873 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1875 Fixed NMEM system to return aligned blocks on the smallest boundaries
1876 that are suitably aligned for all possible types on the particular
1877 architecture YAZ is being built for.
1879 --- 2.0.30 2005/01/04
1881 Fixed numerious warnings that was issued with newer versions of GCC.
1883 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1884 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1887 Make YAZ Generic Frontend Server slightly faster.
1889 Enhance (and reduce) logging for Generic Frontend Server.
1891 Revert YAZ log system so that it flushes every write operation
1892 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1894 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1895 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1896 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1897 will effectively disable old definitions.
1899 --- 2.0.28 2004/11/09
1901 Added yaz_log_time_format which specifies log format using
1904 Added yaz_log_module_level which returns mask for a module. Value
1905 is non-zero mask a if module is enabled; zero if disabled.
1907 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1908 in include/yaz/cql.h.
1910 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1912 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1914 Fixed bug #172: RPM builds does not enable SSL.
1916 Doxyfile.in part of dist. Doxyfile generated by configure.
1918 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1919 are given and the corresponding component does not exist.
1921 Extend CCL documentation in YAZ reference. Describe r=r.
1923 --- 2.0.26 2004/10/01
1925 Fixed MARC->MARCXML conversion to properly deal with
1926 fields, subfields, indicators having non-ASCII characters.
1928 Fixed MARC->MARCXML conversion so that ASCII control characters
1929 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1932 Added YAZ GFS support for conversion from Z39.50 surrogate
1933 diagnostics to SRW surrogate diagnostics.
1935 Bug fix: YAZ GFS did not return schema in explainResponse.
1937 --- 2.0.25 2004/09/30
1939 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1940 now converts recordSchema to elementSetName as well as schema URI.
1942 Fixed bug in COMSTACK that prevented HTTP request packages from being
1945 --- 2.0.24 2004/09/29
1947 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1948 does not require white-space before and after the dash in a range, e.g.
1949 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1952 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1953 due to new GCC removing "redundant" code.
1955 Added yaz-client commands scanpos and scanstep that sets preferred
1956 position and step-size for scan.
1958 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1960 Added CCL utility ccl_qual_buf which parses one or more CCL
1961 spec lines in a buffer.
1963 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1964 of name and value - ignoring empty lines and comments.
1966 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1968 Added odr_get_element_path which returns current element path for an
1969 ODR handle. This utility is useful in error handling or user-defined
1972 Added ODR_PRINT utility odr_set_stream which is is a more generic
1973 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1974 to a write function and pointer to close function. The close function - if
1975 non-NULL - will be called during odr_destroy.
1977 Fixed bug in CCL parser where truncation char was not removed from
1978 right side when truncation=both was in effect.
1980 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1983 --- 2.0.23 2004/08/11
1985 Fix buffer overrun in CQL parser when dealing with proximity (%).
1987 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1988 to UTF-8/UCS conversion is now only based on codetables.xml.
1990 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1992 --- 2.0.22 2004/08/06
1994 Add support for more "commit changes" in ZOOM (uses Extended Services).
1996 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1999 Yet another small fix for configure of SSL.
2001 --- 2.0.21 2004/05/14
2003 Fix SSL libs for configure when --with-openssl=DIR is given.
2005 --- 2.0.20 2004/05/10
2007 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2009 SSL comstack now uses yaz.pem certificate file on server side
2010 by default. Certificate filename can be configured by calling
2011 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2013 Fix bug regarding multiple calls to ZOOM_connection_connect.
2015 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2017 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2018 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2020 ZOOM now allows inspection of X509 peer certificate for verification.
2021 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2023 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2024 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2025 as "modular" but it simplifies things.
2027 Added cs_get_peer_certificate to that returns peer X509 PEM.
2029 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2030 NULL if SSL is unavailable.
2032 Documentation about MARC decoding tools.
2034 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2036 --- 2.0.19 2004/03/30
2038 Rename CHANGELOG to NEWS to follow GNU style packing.
2040 Fix bug with missing initialization of member in init_diagnostics.
2041 This bug affects threaded version of GFS server.
2043 --- 2.0.18 2004/03/20
2045 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2048 Ensure zlib.dll is packed with Windows install.
2050 --- 2.0.17 2004/03/17
2052 Fix encoding of xsd:string to use text instead of CDATA.
2054 Fix endless loop in CQL parser with unbalanced ".
2056 Use a more compact way to store MARC-8 conversion tables.
2058 --- 2.0.16 2004/03/16 Debian only
2060 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2063 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2068 --- 2.0.15 2004/03/01
2070 Another fix for decoding of XML packed records.
2072 --- 2.0.14 2004/02/25
2074 Fixes for Chunked encoding. White space not ignored after length spec.
2076 Update NS and use default NS for SRW diagnostic elements.
2078 --- 2.0.13 2004/02/23
2080 Implement ZOOM_resultset_cache_reset which resets record cache.
2082 Implement ZOOM_resultset_sort which sorts a result set.
2084 Implement chunked HTTP transfer.
2086 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2088 --- 2.0.12 2004/02/16
2090 Added member 'schema' to bend_explain_rr structure so that backend
2091 can specify explain record identifier. Defaults to Zeerex 2.0.
2093 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2095 --- 2.0.11 2004/02/16
2097 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2100 Added init command for yaz-client which sends "extra" init request.
2102 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2103 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2105 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2107 Make ZOOM error code for "invalid query".
2109 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2111 --- 2.0.10 2004/02/05
2113 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2116 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2118 Added option -p <file> to make Generic Frontend Server to write PID file.
2120 Added option -D to put Generic Frontend Server in background on its own.
2122 Make ZOOM C recognize option "password". If unset, "pass" is used
2123 (for backwards compatibility).
2125 Fixed a bug in Generic Frontend Server that could make it crash if a
2126 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2129 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2130 Must be issued before open, in order to be in effect.
2132 --- 2.0.9-6 2004/01/12 Debian/Windows
2134 Make the SRU server more picky WRT unknown params, etc.
2136 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2138 New YAZ client command, options, that sets Z39.50 options.
2140 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2141 options from a string of tokens (one token for each option bit).
2143 Update SRW diagnostic code messages.
2145 --- 2.0.9-5 2004/01/07 Debian/Windows
2147 Handle user defined stylesheet for SRW/SRU.
2149 --- 2.0.9-4 2004/01/06 Debian/Windows
2151 Fix bug in decoding of Content-Length.
2153 --- 2.0.9-3 2004/01/06 Debian/Windows
2155 Fix a bug with decoding of XML packed records.
2157 --- 2.0.9-2 2004/01/05 Debian only
2159 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2161 Fix bug in SRW/SRU diagnostics decoding.
2163 --- 2.0.9 2004/01/05
2165 Fixed bug in Generic Frontend Server which could drop records exceeding
2166 preferred message size. Reported and fixed by Irina Dijour.
2168 Fixed calculation of package size for structured records in Generic
2169 Frontend Server. Reported and fixed by Irina Dijour.
2171 Fixed namespace for SRW/SRU diagnostics.
2173 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2175 --- 2.0.8 2003/12/22
2177 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2178 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2181 CQL changes to reflect recent changes to the specification:
2182 * Documentation talks about context sets instead of index sets.
2183 * Documentation talks about indexes instead of qualifiers.
2184 * The CQL-to-PQF transformer's configuration file now uses
2185 "index.set.name = <attributes>" instead of the old form
2186 "qualifier.set.name = <attributes>". (Both forms are still
2187 understood but the latter is deprecated.)
2188 * CQL terms with no explicit index specified are now interpreted as
2189 cql.serverChoice instead of srw.serverChoice (which of course
2190 behaves exactly the same.)
2192 --- 2.0.7 2003/12/16
2194 MARC conversion can now generate ISO2709 output in another
2195 character set. yaz-marcdump uses this facility if you invoke it
2198 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2199 functions from there can be used from C++.
2201 --- 2.0.6 2003/12/04
2203 Frontend server now transfers memory from decoded packages to stream
2206 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2207 references to show up.
2209 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2210 the ZOOM Abstract API. The older names for the same options are still
2211 also supported for the benefit of old applications.
2213 ZOOM-C supports "implementationId" and "implementationVersion" options
2214 to go along with "implementationName". These allow the user code to
2215 specify identification strings to be sent to servers.
2216 Add OID for the new ExtLite attribute set.
2218 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2219 as requested/supplid by Ere Maijala <ere@atp.fi>
2221 For generic frontend server, reverse the order of
2222 "toolkit-supplied / application-supplied" strings sent as implementationId,
2223 Name and Version. Also, remove the spaces around the slash. This brings
2224 the GFS in line with the behaviour of ZOOM-C on the client side.
2226 Add function ZOOM_scanset_display_term.
2228 yaz-client shows scan displayTerm if present.
2230 Utility yaz-iconv is now installed by default along with the man page
2233 Extend configure check for OpenSSL to use pkg-config where available (such
2236 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2237 server to specify uid/gid/mask for socket using the format
2238 unix:[user=uid,][group=gid,][umask=mask,]file=path
2239 If file= is omitted the existing format is assumed, e.g.
2241 in which case the mask is 0666 (rw for everybody).
2243 Major restructure of YAZ source. All source in libyaz is in src directory.
2244 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2245 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2247 Added man page for utility yaz-marcdump (used to be called marcdump).
2248 yaz-marcdump is installed by 'make install'.
2250 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2251 of incoming package failed.
2253 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2255 Change prototype of odr_perror: add const to message string.
2257 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2259 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2260 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2261 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2262 DNS lookup. There should not be any compatibility problems with this
2263 assuming that blocking=1 or 0 is used.
2265 Fix bad reference in UNIX comstack in function cs_addrstr.
2267 Fix for compilation on AIX.
2269 The generic front-end server (server/seshigh.c) now supports returning
2270 Init diagnostics to the client in User-information-field, in
2271 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2274 --- 2.0.4 2003/09/04
2276 Allow any CQL relation (not just all,any,exact,scr).
2278 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2279 that features the same UI.
2281 Implemented command update0 in YAZ client which is equivalent to
2282 update but uses old of Ext Update ASN.1.
2284 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2285 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2286 Previously no OID was used for this info.
2288 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2289 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2290 returns 'malformed search term' otherwise.
2292 SortResponse member resultCount now set to NULL in sort handler of
2295 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2298 Add three new utility functions for translating OIDs between various
2299 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2300 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2301 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2302 char *oid_to_dotstring(const int *oid, char *oidbuf);
2303 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2305 Reverted modifications for ES Update definition for z_IU0Update
2306 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2307 is back to YAZ 2.0.2.
2309 String value attributes for CCL parser.
2311 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2312 which their FirstSearch server returns in Init responses, sometimes
2313 carrying useful diagnostic information when Init fails. This has the
2314 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2315 "z39.50/oclcui.asn", where its definition is somewhat different from
2316 what OCLC document on their web-site, as required to interoperate with
2319 Support for anonymous authentication in yaz-client. Use the command
2322 * Fix the OID of the Index Data-local "admin" Extended Service from
2323 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2324 the 1000, which indicates a locally-defined OID, was a mistake.
2326 --- 2.0.3 2003/06/20
2328 Fix CCL directive @case handling so that it affects string match for
2329 both CCL keywords and qualifiers.
2331 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2332 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2333 Decoder has been updated with ASN.1 changes as listed in
2334 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2335 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2336 z_IUUpdate, remains unchanged.
2338 ZOOM_record_get may now return a record in a specific character set.
2339 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2340 "from" is the character set of record as returned by target. "to" is
2341 the character set to be returned. If omitted, "to" is UTF-8.
2343 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2345 New ODR utility, odr_getelement, which returns name of element for
2346 which encoding/decoding failed.
2348 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2349 in cases where a required element was omitted.
2351 Bug fix: some MARC8 sequences were not converted.
2353 New ZOOM option "step" which specifies number of records to be
2354 retrieved in one chunk. Used in conjunction with "start" and "count".
2356 SRW support for yaz-client. Use scheme http: to use it, e.g.
2359 yaz-client no longer does (un)intelligent character set conversions
2360 by default. Can be enabled with charset and marc_charset commands.
2362 xmalloc trace fix for 64-bit systems such as DEC alpha.
2364 Solaris 2.6 compile fix.
2366 New function, cql_strerror() translates SRW error codes, as returned
2367 by cql_transform_error(), into human-readable English strings. Used
2368 in yaz-client diagnostics when appropriate.
2370 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2371 converts it into a type-1 query which is sent to the server. This
2372 makes CQL available for use with all Z-servers, as opposed to the tiny
2373 minority that can handle CQL queries themselves.
2375 --- 2.0.2 2003/04/28
2377 New Debian package layout similar to the Redhat Package layout.
2379 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2380 and search result respectively.
2382 --- 2.0.1 2003/04/25
2384 Redhat package is now several packages: libyaz (runtime libraries),
2385 libyaz-devel (development and documentation, and yaz (utility programs).
2386 Package spec file by Morten Bogeskov.
2388 New member 'schema' in struct bend_fetch_rr which the name of requested
2389 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2390 handler MAY set this to reflect the schema of the returned record.
2392 New member 'display_term' in struct scan_entry. GFS now sets member entries
2393 and allocates scan entries to be filled by user scan handler. In previous
2394 version, entries member was allocated by the scan handler. That still works,
2395 but the GFS will ignore member display_term - assuming it was NOT set by
2396 the handler. The fact that the GFS now allocates the entries both allows
2397 for new members and makes a scan handler easier to write.
2399 Fix CQL lex buffer overflow.
2401 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2402 SRU default recordPacking is string.
2404 SRU protocol support for frontend server.
2406 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2408 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2410 Added scan for the ZOOM shell (zoomsh).
2414 * String Identifers for Schemas (Amendment 5).
2415 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2416 Old definition for schema
2417 Odr_oid *schema; /* OPT */
2422 Z_InternationalString *uri;
2423 #define Z_Schema_oid 1
2424 #define Z_Schema_uri 2
2427 * resultCount parameter to Sort Response (Amendment 1).
2428 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2430 Support for SRW 1.0 over HTTP. This is an optional feature and
2431 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2434 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2435 on the same port. SRW SearchRetrieveRequests are mapped
2436 to bend_init,bend_search,bend_fetch,bend_close.
2438 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2440 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2441 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2443 ZOOM connections are SRW based if schem http is used for hostname
2444 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2445 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2447 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2448 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2449 distance=n, order=true/false, relation=le, prox unit=word. If
2450 n is omitted, distance 1 is used.
2452 Fixed problem with C compiler include path in wrong order.
2454 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2455 on Solaris. Patch from Ko van der Sloot.
2457 New MARC decode API. All new functions operate on a yaz_marc_t
2458 handle. The most important new functions are: yaz_marc_create,
2459 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2460 decode and destroy respectively. Decoder can produce formats
2461 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2462 include/yaz/marcdisp.h.
2464 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2465 to UTF-8, UCS-32, wchar_t or Latin-1.
2467 * Prototypes for yaz_iconv_-functions moved to separate header
2468 include/yaz/yaz-iconv.h.
2470 Make a few private functions 'static' in unix.c. This prevents
2471 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2473 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2474 are set when Init Response is received.
2476 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2477 but returns diagnostic set as well.
2479 New function yaz_strerror which is a portable wrapper for
2480 strerror/strerror_r/GetLastMessage.
2482 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2483 is returned for MARC. If type is "oai", then OAI MARC is returned.
2485 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2488 --- 1.9.2 2002/11/26
2490 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2492 Fix bad race conditions on SIGTERM and terminate gracefully in
2495 Move retrieval (data1) module to Zebra since nobody seems to be
2498 Add GRS-1 render for ZOOM using same format as yaz-client.
2500 --- 1.9.1 2002/10/05
2502 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2504 Fix broken ESpec handling in data1 module.
2506 SGML reader parses comments and makes them part of the data1 tree.
2508 Added several type casts so that YAZ compiles as C++ code.
2510 ZOOM didn't handle PDU encoding failures properly.
2512 Added more Bib-1 diagnostics (approved extensions).
2514 GNU configure: better check for iconv.
2516 More portable use of accept, getpeername. Check for socklen_t. Use
2517 int/size_t if socklen_t is not defined.
2521 PQF parser rejects bad queries - including those with extra
2522 characters in them. PQF parser used to silently ignore that.
2523 Cleaner API for PQF added, which allows you to get detailed
2524 error information for bad queries (see yaz/pquery.h).
2526 Fixed bug in ZOOM_record_get for type "database".
2528 Implemented mini iconv library supporting conversions between
2529 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2531 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2533 --- 1.8.9 2002/08/20
2535 Fixed ZOOM C record cache so that preferredRecordSyntax and
2536 elementSetName is used to check for already fetched records.
2538 --- 1.8.8 2002/08/02
2540 Added three members in bend_initrequest structure to facilitate
2541 character set negotiation.
2543 Fixed a bug in frontend server that could cause indefinite
2544 loops under rare conditions.
2546 Revised character set utilities (charneg.h) so that encoding
2547 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2549 For PQF, directive @term <type> sets term type for Scan/Search.
2550 Here <type> is general, string, numeric, null. The term type
2551 is inherited - just like @attr.
2553 New call odr_set_charset that sets character set conversion for
2554 international-strings on a ODR stream. Prototype is:
2555 int odr_set_charset(ODR o, const char *to, const char *from);
2556 The InternationalString is still represented as C string in YAZ
2557 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2558 won't). On the protocol level, you can use any encoding.
2560 Support for UNIX sockets in ZOOM.
2562 Solaris recv sometimes returns errno == ENOENT. It is treated as
2563 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2565 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2566 both client and server. Code by Morten Bogeskov.
2568 --- 1.8.7 2002/05/22
2570 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2571 that they can be used directly from Visual Basic. You must recompile
2572 your windows APP if you're using ZOOM.
2574 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2575 Commands "lang" and "charset" sets language and character set respectively.
2576 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2577 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2579 Attributes from multiple CCL fields may be OR'ed rather than merged
2580 using directive "@field or". Fields are still merged by default -
2581 equivalent to "@field merge".
2583 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2586 Fixed bug in zget for parameter ExtendedServicesResponse.
2590 --- 1.8.6 2002/03/25
2592 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2594 Client displays USR.1:SearchResult-1 (hits per term).
2596 Additional Search Info for search in Generic Frontend Server.
2598 Fixed CCL parsing of "field=s".
2600 WIN32 installer - using the excellent NSIS software from nullsoft.
2602 Fixed CCL parsing of "field = - <number>".
2604 Added function yaz_marc_decode that decodes MARC for line mode
2605 display or XML (similar to that used by JZKit).
2607 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2608 Z39.50. But ISO/ILL was, however.
2610 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2611 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2613 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2614 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2616 --- 1.8.5 2002/02/03
2618 New YAZ client features: Command completion and new commands:
2619 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2620 Code provided by Jacob Poulsen.
2622 New call oid_trav, that visits all registered OIDs via callback.
2624 Function ZOOM_record_get now returns const char pointer rather than
2625 void pointer. It saves a lot of type casts.
2627 For YAZ client, command "auth" now allows you to set authentication
2628 in IdPass style. It is enabled when three tokens are given - order
2629 is user, group and password.
2631 Fix memory leaks in MARC record handling for ZOOM.
2633 New option for YAZ client, -k <kilobytes> that sets
2634 maximum record size. Similar to -k option for generic frontend
2635 server and yaz-ztest.
2637 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2639 Prefix query parser reports "fail" when bad attribute set is given.
2641 Fix in MARC decoder. Proximity logging. Fix for attribute set
2642 in scan handler for server. Patches by Shigeru Ishida.
2644 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2647 Configure option --with-openssl=<dir> now works when a directory is
2648 specified. Patch provided by Morten Bogeskov.
2650 New option for YAZ client, -u <auth>, that sets authentication.
2652 ZOOM fix: error information was sometimes "missing", since error
2653 was cleared/reset too when it shouldn't.
2655 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2657 --- 1.8.4 2002/01/04
2659 Scan for ZOOM API. New object ZOOM_scanset. New functions
2660 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2661 ZOOM_scanset_destroy.
2663 New ZOOM function, ZOOM_connection_last_event, that returns type
2664 of last event (such as "receive data", "send data", "apdu received",
2667 New ZOOM option, schema, that specifies schema for retrieval.
2669 New CCL feature. Qualifiers can be aliases for one or more
2670 other qualifiers (if more than one is given, OR is used).
2672 ZOOM uses named result sets if target supports it.
2674 Two new YAZ client commands: . (dot, which sources a script of YAZ
2675 client commands), and ! (to execute shell command.). Implemented
2678 Working on Debian packages.
2680 --- 1.8.3 2001/11/19
2682 YAZ client enables named result sets only if target supports it.
2684 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2686 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2687 with key="host" to get same result.
2689 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2690 Function Z3950_resultset_record(s) returns references to records
2691 "owned" by resultset. To become owner use Z3950_record_clone.
2693 Function z_ext_record handles Extended Services. Thanks to
2696 --- 1.8.2 2001/11/12
2698 CCL Parser fix: ignore token comma when dealing with and-lists.
2700 Documentation updates for COMSTACK.
2702 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2703 Changed prototype Z3950_records. For some functions, int parameters
2704 were changed to size_t.
2706 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2709 New MARC decode/display function, marc_display_exl, which properly rejects
2710 non-ISO2709 records. YAZ client uses it.
2712 --- 1.8.1 2001/10/29
2714 Fix bug: local attribute set wasn't set correctly in PQF strings.
2718 * Old Z39.50 codecs no longer supported.
2720 Added ZOOM C binding. See http://zoom.z3950.org/
2722 Renamed states for COMSTACKs to avoid confusion with events.
2724 Implemented cs_look and proper cs_rcvconnect.
2726 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2728 Configure detects POSIX threads on OpenBSD.
2730 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2731 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2733 When error is returned from present handler, non-surrogate diagnostic
2734 is returned in present response (and fetch handler is no longer called).
2736 * Minor adjustments to pquery parser (PQF). Token characters may be
2737 escaped by using backslash (C-style).
2739 PQF parser allows string attribute values to be specified. For @attr,
2740 non-numeric characters after the equal-sign are treated as strings
2741 (e.g. @attr 9=title).
2743 CCL trunction character may be defined (@truncation in file)
2745 * function zget_ExtendedServicesRequest sets waitAction to
2746 waitIfPossible (was wait).
2748 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2751 CCL operator names may be set in field definition files (CCL_bibset).
2752 See ccl/bib1 for an example.
2754 Fixes in ASN.1 compiler for C++ compatibility.
2756 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2757 and "op_or" to avoid conflict with C++.
2759 Fixed problem with GNU readline detection on Redhat 7.0.
2761 Added step-size for Scan backend handler.
2763 Fixed bug that made the frontend server crash when no attribute
2764 set was specified for scan.
2766 Front-end server automatically switches to original working directory
2767 when installed as an NT service. Previously -w had to be specified to
2770 Added extended attributes for retrieval module (data1), so that data1
2771 records carry d1_readXML/SGML attributes. d1_read also supports
2772 null-data rules ( <tag/>)
2774 On UNIX when POSIX threads are available, a separate library libyazthread
2775 is created. Programmers should link with that library and the yaz library
2776 when using threads. The reason for the split was that some applications
2777 on Linux, such as Apache, doesn't work well when using shared objects that
2780 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2781 (or any frontend server) in SSL mode by specifying ssl: followed by
2782 address. Only tested on UNIX.
2784 Added feature for CCL module. Virtual structure s=al or s=ol generates
2785 and-list and or-list respectively instead of phrase search.
2789 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2790 log_mask_str. This was done to avoid name conflicts with other libraries
2791 (such as other PHP extensions).
2793 Added raw OID member for preferred record syntax (request_format_raw)
2794 and returned record syntax (output_format_raw) for backend fetch method.
2796 Config file yaz-config now accepts options so that it returns specific
2797 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2799 Shared library support for UNIX using GNU libtool.
2801 * Modified backend interface. Request/Response struct's replaced by
2802 one read/write C struct. For example bend_fetchrequest and
2803 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2804 Every handler - even search has to be registered in bend_init
2805 handler. This means that the YAZ library no longer refers to
2806 external functions and it makes it possible to make the whole
2807 thing a single DLL/SO.
2809 Added Segment handler for backend server.
2811 Added Zmbol/Zebra administrative functions to YAZ client.
2813 Threaded frontend server on UNIX (when POSIX Threads are available).
2814 Starting the server with option -T enables multi-threading.
2818 Added configure option --enable-comp/disable-comp to control use
2819 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2820 located in sub directory asn.
2822 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2823 in ${exec_prefix}/bin along with the other programs yaz-client and
2826 GNU automake used to maintain makefiles.
2828 Added several OID's.
2830 Changed retrieval module so that we can load records with no abstract
2831 syntax defined. Tagpaths in these records are fully composed of string
2834 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2838 On UNIX, the generated makefile now supports a proper 'make install'.
2839 The prefix can be set via GNU configure to set the install location
2840 (default is /usr/local).
2842 * YAZ programs client and ztest were renamed to yaz-client and
2843 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2844 locations, such as /usr/bin,/usr/local/bin,etc.
2846 * YAZ Header files were moved from include to include/yaz. YAZ Header
2847 files are referred to as include <yaz/log.h> rather than <log.h>.
2848 The YAZ include path (-I ..) is therefore the same as before. Programmers
2849 should update their #include statements or use -Ipath/include/yaz
2850 instead. The main motivation for doing this change is that YAZ header files
2851 can be installed in "standard" locations /usr/include,/usr/local/include
2852 without introducing conflicts, since ALL YAZ header files are stored
2853 in subdirectory yaz (under /usr/include for example).
2855 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2856 rather than project/workspace files. We switched because project files
2857 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2860 Changed name of logging function, logf, to yaz_log, to prevent name
2861 clash with some math-log functions. The YAZ header log.h defines logf
2862 to yaz_log (#define) so there should be no incompatibilities by this
2865 Added bend_start/bend_stop handlers for server. These handler are
2866 called on start/stop of server. For windows they are called whenever
2867 a service is started/stopped.
2869 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2870 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2871 in util/yc.tcl. The auto-generated C code structures are, in a few
2872 cases, incompatible with the old decoders. There are differences in the
2873 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2874 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2875 The preprocessor variable ASN_COMPILED is defined when the compiled
2876 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2877 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2878 wish to use the old encoders/decoders you can specify --disable-yc
2881 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2882 version so that it supports both new - and old version of DB Update
2884 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2885 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2886 change. The name parameter can be set to 0 in which no name is specified
2887 for the construction. The macros odr_implicit and odr_explicit sets name
2888 parameter to zero for the construction involved. New macros
2889 odr_implicit_tag and odr_explicit_tag are similar to the others,
2890 except that a name parameter is added. For programmers' that don't use
2891 ODR they probably only need to change the call to z_APDU and z_External.
2893 Added access control facility by interfacing the TCP wrapper library.
2894 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2895 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2896 name of the daemon and enables the access control as specified in
2897 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2899 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2900 den Dool <H.M.vdnDool@kub.nl>.
2902 Added reference ID parameter to most functions in server API - refer
2903 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2905 Changed name of ccl library to libccl.a (was ccl.a).
2907 Fixed bug in decoder for Explain (Category TargetInfo).
2909 Added support for GNU readline in client. Thanks to Jacob Poulsen
2910 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2912 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2913 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2914 IMPLEMENTATION! This change was made to the development version before
2915 the ZIG decided to retract the amendment. If any users MUST be
2916 compatible with the original Update definition, PLEASE CONTACT US, and
2917 we will include a separate definition corresponding to the old Update
2918 ES. Note that because of the change to the ASN.1 of the
2919 TaskPackageRecordStructure we cannot define a single structure that
2920 will support both versions.
2922 * Added const modifier to buffer parameter for some ODR/BER encoding
2923 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2924 completeWAIS, odr_dumpBER.
2926 Fixed bug in client.c which caused a crash when a scanResponse didn't
2927 contain positionOfTerm.
2929 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2930 * will cause an error in a client if a non-YAZ target sends both a
2931 * list of Scan entries and non-surrogate diagnostics.
2933 Retrieval module enhancements. Tag sets may be typed in the reference
2934 to it. From the .abs-file the "tagset" directive takes a third optional
2935 integer type for the tag set referenced. From a .tag-file the "include"
2936 directive takes a third optional type as well. The old "type" directive
2937 in the tag set itself is still recognized but acts as the default type
2940 Backend interface change. Individual Scan terms returned from bend_scan
2941 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2942 in include/backend.h.
2944 Retrieval module enhancements. Multiple tag sets and attribute sets may
2945 be specified in abstract syntax specs. Revised the error/warning for
2946 logging messages reported by the retrieval module when reading the
2949 Object Identifier system (oid_..) changed. The API is backwards
2950 compatible but the oid-routines now allocates new OID's when needed.
2951 Raw OID's may be specified in oid_getvalbyname.
2953 YAZ now uses GNU configure to generate Makefile(s).
2955 * Minor changes in some of the member names of DeleteResultSetRequest and
2956 DeleteResultSetResponse. See include/proto.h.
2958 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2959 and added member 'languages' in TargetInfo (which was missing).
2961 Changed the way attribute sets are handled in the retrieval
2962 module. These are now cached, just like the abstract syntaxes
2965 Changed YAZ so that it links with compiled ASN.1.
2967 Added Explain-schema definitions and mapping routines. The following
2968 Explain categories have been implemented: AttributeDetails,
2969 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2971 Fixed minor bug in Windows version of Server Library.
2973 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2975 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2977 Added EXTERNAL: UNIverse Resource Report (non-standard).
2979 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2980 ENUMERATED and SET OF.
2982 * Added 'const' to some of the char pointer arguments for the
2983 functions, data1_read_node, data1_getelementbytagname,
2984 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2987 Fixed bug in data1_insert_taggeddata - the last_child member of
2988 parent wasn't initialised.
2990 * Changed data1_read_record and data1_read_node so that the supplied
2991 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2992 doesn't refer to any parts of the "SGML"-buffer.
2994 Fixed bug in server library (Windows version of statserv_remove).
2996 * Changed code so that it compiles as C++. The type definition
2997 of Odr_fun which is a member of Odr_arm was changed. The result is,
2998 that an explicit typecast is needed for the fun pointer when
2999 using Odr_arm - as in:
3000 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3002 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3004 Implemented the new structured date and time definition as approved
3005 by the ZIG. Added schemaId element to the specificTag in Espec-1
3006 (also approved at the last ZIG). Thanks to RVDM.
3008 Added some Object identifiers (RVDM).
3010 Changed the Update Extended Service (RVDM).
3012 Added command "refid" to client which specifies referenceId for
3013 the following requests.
3015 Implemented extended service handling for server. See ztest.c
3016 for an example as well as backend.h. New handlers are registerd
3017 in the Init handler.
3019 * Changed interface for sort in server.
3021 Added new members to statserv_options_block. It allows a server
3022 to read options from another source than just the command line. Thanks
3023 to Charles Woodfield.
3025 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3026 renamed to zboolean. Some C++ compilers complained about the name.
3028 Minor changes to gils.abs. Added index 's' (sort) on title
3029 and date/time-last-modified.
3031 --- 1.4pl2 1998/1/30
3033 Fixed bug in server library regarding inetd mode (-i). This bug
3034 was introduced by release 1.4.
3036 --- 1.4pl1 1998/1/29
3038 Added sort facility in client and backend server interface.
3040 Fixed problem with dependencies in Makefile(s).
3042 Fixed bugs for encoders/decoders of extended services and
3045 Implemented sub-tree feature for schemas. Sub-trees are
3046 referenced in *.abs-files. See explain.abs for an example
3047 of the use of this feature.
3049 Modified bib1.att; local attributes for ANY didn't include
3050 ANY itself (only affects use of the retrieval module).
3052 Fixed bug in plain SGML reader in function data1_read_node:
3053 tags with prefix "var" was incorrectly interpreted as variants.
3055 Added feature "sub-schemas" to enable references to - and definitions
3056 of - group of elements.
3058 * Removed member parent from type data1_element (in data1.h).
3060 Implemented function odr_nullval() that returns the value of
3063 * Removed member num_children from data1_node (in data1.h).
3065 Made NT service interface part of the server library. The
3066 function statserv_main uses the NT service when required and
3067 calls the statserv_start / statserv_close routines.
3069 Routine zget_SearchRequest and zget_PresentRequest fills
3070 resultSetName/Id member with "default" instead of "Default".
3072 Fixed memory leak in server. Request queue member wasn't freed.
3074 Fixed nmem_exit so that memory is freed.
3078 Revised the CCL parser utility to be thread safe.
3080 Added function, oid_ent_to_oid, to replace the function
3081 oid_getoidbyent, which is not thread safe.
3083 * Added nmem_init and nmem_exit to initialize and release
3084 NMEM resources. Function nmem_init should be called once in the
3085 initial thread before NMEM/ODR is used. statserv.c and client.c
3086 have been changed accordingly. The change was necessary to make
3087 NMEM thread safe. The NMEM memory pool is shared amongst threads
3088 in a process. Unix-based applications will still work fine without
3091 Added NT Services interface for the the Z39.50 (statserv) Server.
3092 Refer to the ztest.c source on the usage.
3094 Windows 95/NT port using MSVC5.0. Project files are included in the
3097 * Defined new 'global' handle for the retrieval (data1) system. The
3098 new handled, data1_handle, describes the state of the data1 system.
3099 This handle is passed as first argument to virtually all
3100 data1 related routines. The functions data1_create and data1_destroy
3101 creates and destroys a data1 handle respectively.
3103 Added ODR encode stream member to all backend request structures
3104 init, search, scan etc. This stream should be used to allocate all
3105 memory used for the response when thread safe operation is needed.
3107 Changed the comstack utility, cs_addstr, to be thread safe. The
3108 returned hostname string returned by the function is now part the
3111 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3112 function. The cs_straddr takes a COMSTACK handle as argument, so this
3113 function must be used after cs_create and before bind/connect.
3114 This function is thread safe.
3116 Moved test server to 'ztest' directory - generic server code still
3117 in 'server' directory.
3119 Made prefix query (pquery.c) utility thread safe.
3121 Added new function modifier YAZ_EXPORT to 'export' public DLL
3122 functions when using windows (see include/yconfig.h).
3124 Added definitions to the OID database (util/oid.c) (RVDM).
3126 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3128 Added call to ccl_rpn_delete in client program.
3130 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3131 release of RPN structure.
3133 Added support for C++, headers uses extern "C" for public definitions.
3134 With input from RVDM.
3136 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3137 Thanks to Ronald van der Meer (RVDM).
3139 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3141 Added support for private extensions to the OID database
3142 (oid_setprivateoids()). Thanks to RVDM.
3144 Added optional, physical ANY (key replication)
3146 Fixed null-reference problem in GRS-1 output filter.
3148 Proximity operator added to Prefix Query Format (PQF).
3150 In test client command "base" accepts multiple databases.
3152 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3156 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3158 Smallish bug-fixes in the new encoders/decoders (explain).
3160 Bug fixed in DeleteRequest.
3162 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3164 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3166 Added SOIF syntax (using private OID for now) to retrieval module and client.
3168 Added Update extended service.
3170 Added SearchResult-1 additional info structure.
3172 Added optional CCL (ISO8777) interpreter as separate module. Available
3175 --- 1.2 1996/6/10 (1st anniversary release)
3177 Added Summary record syntax. Lightly tested.
3179 Added OPAC record syntax. Untested.
3181 Added ResourceReport service encoders/decoders. Untested.
3183 Fixed bug in z_Unit - wrong tagging on unitSystem.
3185 Fixed bug in the DiagRecs decoder.
3187 Added options for max PDU size and session timeout to frontend-server.
3189 Added documentation of query-language parsers and other supporting utilities.
3191 [frontend-server] Added Attribute set to the bend_scanrequest API.
3193 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3194 surrogate diagnostics were generated.
3196 [retrieval] Allow multiple local values for attribute.
3198 [retrieval] Allow multiple attributes per element in .abs files. index type.
3200 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3202 --- 1.1pl2 1996/4/10
3204 Minor changes, mostly specific to Zebra's requirements (retrieval)
3208 Repaired bug in frontend server when running multiple listening
3209 endpoints in dynamic mode.
3211 z_External() now won't break if a known, ASN.1 value comes encapsulated
3212 in an octet-string. The value will pass through unmodified in an Odr_oct.
3214 Added a bit of code to the demo client to decode & display
3215 ASN.1-structured records represented in the octet-aligned branch of
3216 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3218 Added z_ext_getentbyref() to the ASN module. Doc updated.
3220 * Completed the SCAN definition in the ASN module. This may break SCAN
3221 code based on older YAZ-versions at compile-time. The fix is easy -
3224 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3225 under the SCAN definition. Remember to initialize this, server-people.
3227 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3228 that this does not extend to ODR and ASN.
3230 Comstack allows insertion of established socket (primarily for
3231 inetd-operation of servers). Doc updated.
3233 Front-end server can now start from the inetd in TCP mode. Doc
3236 --- 1.0pl4 1996/1/24
3240 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3241 the rank and record number.
3243 Adjustments to the frontend server.
3245 Fixed diagnostic BER dumper. It ignored the file argument.
3249 Various changes to retrieval module.
3251 Changed the union discriminators of the protocol files from enums to
3252 ints paired with #defines.
3254 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3257 *Changed operator in the RPN structure to 'roperator', again to avoid a
3260 Fixed problems in Explain decoders/encoders.
3262 --- 1.0pl2 1995/12/6
3264 Memory bug in log module fixed.
3266 --- 1.0pl1 1995/12/5
3268 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3270 Bug in Explain DatabaseInfo module fixed.
3272 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3276 The shift to v1.0 signals that we now consider the *core* functionality
3277 of YAZ reasonably stable (the core being more or less equivalent to
3278 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3279 tested (Explain not at all - though that will happen soonish).
3281 Minor changes to code to support Windows port.
3283 Various minor changes after we're getting to use GRS-1 & co. more.
3285 Added Espec-1 format.
3287 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3288 of the protocol and it cannot be selected when encoding (maps into 'string'
3289 when decoding). Needed to talk to some servers.
3291 Demo client can request simple element set names.
3293 Added Diagnostic Format encoders/decoders.
3295 Added simple Close handling to frontend server (no hooks for resource
3296 reporting yet), and demonstration client.
3298 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3300 --- 1.0b3 1995/08/24
3302 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3303 handled incorrectly when records were requested in the searchResponse. This
3304 will only affect you if you use the frontend-server.
3306 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3307 Test-client will ask for and print GRS1. Ztest will return dummy records
3310 Added Explain encoders/decoders to the service-level API. Untested.
3312 Added Extended Services: Item Order encoders and decoders to the Service-
3313 level API. Untested. We could use a recent copy of the pertinent bits
3314 of the ILL protocol to add those bits.
3316 Added diagnostic format 1 encoders/decoders to the service-level API.
3319 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3320 odr_cons.c, which causes a more correct output.
3322 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3323 was always set to 0 when no records were requested in the searchRequest.
3325 * Added better external-handling. This shouldn't harm old code that
3326 *encodes* externals. It can break code that looks for a
3327 'single-ASN1-type' representation, since those types that are known
3328 are now decoded immediately. Look at the SUTRS sample code in
3329 seshigh.c and client.c. Documentation updated.
3331 Handling of structured records in bend_fetchresponse. Length -1 marks
3332 structured record, type is deduced from format field.
3334 --- 1.0b2 1995/06/27
3335 Fairly quick maintenance release to add SUTRS support.
3337 Fixed handling of SUTRS records in the demonstration client.
3339 * Added format field to the bend_fetchrequest and bend_fetchresponce
3340 structures of the backend API (frontend server). When the record is
3341 returned, the value of the format field is mapped to an OID. The
3342 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3343 of the record. The special value VAL_NONE in the bend_request means
3344 that no specific format was requested by the client. Documentation
3345 updated accordingly. Test server (ztest) will return a fixed dummy
3346 SUTRS record if your client requests SUTRS.
3348 Documentation updated accordingly.
3350 You can now set external libraries and RANLIB support in the top-level
3354 First public release.
