3 daemon: log total number of bad signals from child on stop so that it
4 is more easy to spot problems with child worker processes.
6 retrieval: empty backend name attribute omits element set
7 from being used in retrieval.
11 Implement Solr sort strategy "solr", similar to sru11 sorting.
12 This will implement the correct parameters on Solr requst to do
17 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
20 MARC: Extra/missing indicator handled for MARCXML.
21 The indicator length is given in header and is the same for the
22 whole record. If attributes ind1, ind2 are missing, then content
23 character defaults to blank. Extra indicator attributes (beyond)
24 indicator length are treated as an error.
26 Reformat: delete trailing whitespace
30 MARC: fix non-ASCII characters for leader. This is to ensure we can
31 generate XML in UTF-8.
33 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
34 in one node with structure word.
38 yaz-json-parse: JSON output may be pretty printed by using option
41 Increase default value of max message for Z39.50 Init for GFS, ZOOM
42 and yaz-client. Old value was 1 MB. New value is 64 MB.
46 yaz-client: don't display bogus records from SRU servers. Some SRU servers
47 return more records than given by *maximumRecords*. Skipping those in
50 record_render: simplify buffer return handling and fix at least one bad
51 memory reference, that broke the test_embed_record sometimes.
53 Allow http://user:pass@host notation for yaz_url_exec.
55 zoomsh: allow shell command to be executed. Via the system(3) call.
57 yaz_poll: Allow num_fds == 0
59 yaz-client: fix bad encoding of "itemorder item". The itemorder
60 item <no> - command forgot to use length of encoded Item Request
61 package. Error present since YAZ 3.
63 yaz-ztest: fix bad usage of session handle. Bug was introduced when
64 result sets were saved (271a9c83).
66 SRU recordPacking: guess record packing in response rather than looking
67 at the recordPacking element which, OF COURSE, changed semantics in SRU
70 Decode SRU 2.0 responses. The official namespace for responses, according
71 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
72 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
73 nature.com's server, however, usee namespace
74 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
75 we are now using a glob-expr to match up the namespace. ZOOM C and
76 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
77 I can not find a single real example showing the "real" namespace in
78 the documentation from OASIS. The namespace for requests is different
79 from responses, but this is not added to YAZ yet, when we don't encode
84 zoom/record_render: add support for Base64 decoding fo MARC records
85 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
86 which will decode base64 + ISO2709 marc-8 encoded material from text node
91 Add missing definitions ZOOM_resultset_get_facet_field_by_index
92 and ZOOM_resultset_facets_names.
94 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
97 Change APDU dump printing to avoid long leading blanks. For levels 16
98 or larger the level is shown and the indentation is truncated but
99 recursed with modula 8. This makes it still reasonable easy to read
100 - even for nested BER dumps.
102 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
103 return 0 (incomplete package) in case where the BER package was
104 considered too nested (return value of -2).
106 dumpber: lines of level 15 are not indented further. Two spaces per
107 indentation; indentation 15 or more is indented to a fixed indentation
108 and augmented with a level=<no> indication.
110 zoomsh: increase max size of command+args
112 GFS: No limit in RPN buf size in CQL to RPN conversion.
114 --- 4.2.33 2012/05/09
116 New function for daemon utility, yaz_daemon_stop .
118 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
120 --- 4.2.32 2012/04/25
122 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
123 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
125 --- 4.2.31 2012/04/23
127 YAZ daemon utility relays SIGUSR1 to child process.
129 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
130 would result in en empty database list - which in turn would result in
131 encoding failure for search.
133 Fix reading beyond string in yaz_sort_spec.
135 --- 4.2.30 2012/04/11
137 Add two new SRU diagnostics:
138 236: Access to specified database denied
139 1015: Init/AC: Maximum number of simultaneous sessions for Userid
141 Document the very useful ZOOM-C option "apdulog".
143 CQL to RPN: term may be passed through verbatim. This is enabled with
144 truncation.cql . The assumption being that the term is already CQL.
146 --- 4.2.29 2012/03/20
148 record_conv: leader spec may be given for marc element.
149 The leader spec is given as attribute leaderspec for element marc.
150 For example to convert a MARC21 record from MARC-8 to UTF-8:
151 <marc inputformat="marc" outputformat="marc"
152 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
154 record_conv: allow user-XSLT params. For example:
155 <xslt stylesheet="MARC21slim2DC.xsl">
156 <param name="myparameter" value="myvalue"/>
157 <param name="otherparameter" value="othervalue"/>
160 record_conv: fix error handling for missing marc charsets.
162 CQL: fix extra terms in wrong order.
164 --- 4.2.28 2012/03/06
166 record_conv: modify new API for conversion types. The conversion types
167 may be passed in new functions yaz_record_conv_configure_t and
168 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
170 Avoid mixed statement/variable declare; fixes compilation with Visual
173 --- 4.2.27 2012/02/28
175 Add non-standard SRU diagnostic: 235: "Database does not exist".
176 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
177 Update SRU to Bib-1 diagnostic maps accordingly.
179 CCL: add two new diagnostics for unsupported masking. The new
180 diagnostics are: "Embedded truncation not supported" and
181 "Single charcacter mask not supported".
183 --- 4.2.26 2012/02/23
185 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
187 --- 4.2.25 2012/01/11
189 Build YAZ for Ubuntu Oneiric.
191 CCL: allow parantheses for proximity operands. For example CCL query
192 (a) % (b) is now allowed.
194 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
195 marked dead, rather then being destroyed. If not, the session memory is
196 being free'd before the search/scan handler is finished. Also destroy
197 'request' memory in request_release rather than in various places,
198 which resulted in leaks from time to time.
200 --- 4.2.24 2011/12/21
202 cql_sortby_to_sortkeys: honor sort prefix.
204 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
205 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
206 The rpn2cql family of functions now always returns quoted CQL terms.
208 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
210 --- 4.2.23 2011/12/15
212 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
213 sequence is treated as one. For example, &&a=b&&&c& is identical to
216 --- 4.2.22 2011/12/05
218 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
219 APDUs for a connection to a WRBUF.
221 --- 4.2.21 2011/11/23
223 Fix cql_sortby_to_sortkeys. Completely broken before.
225 Make CCL's @truncation work again.
227 --- 4.2.20 2011/11/09
229 New ZOOM connection setting: tproxy. It's like proxy, but does not
230 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
231 to set resolved address + port for a connection outside ZOOM itself.
233 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
235 --- 4.2.19 2011/11/07
237 Fix uninitialized variable in Solr spell support (could cause SEGV
238 for SRU response decoding).
240 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
241 back-end's addinfo through into the ZOOM response addinfo.
243 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
244 they are separated by a colon and a space rather than simply
247 --- 4.2.18 2011/10/28
249 Add support for Solr spell-checking/suggestions through ZOOM.
250 If a Solr target has been configured correctly for spelling-checking
251 and suggestions, these will now be returned on the ResultSet option
252 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
254 --- 4.2.17 2011/09/28
256 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
257 with a flag whether to substitute escape sequences or not.
259 --- 4.2.16 2011/09/22
261 Fix nmem_strsplit_escape to substitute escape char properly.
263 New option for zoomsh -e , which makes it abort on first error and
264 return process exit code to indicate success/failure.
266 YAZ options utility supports special option -- which makes all it treat
267 all following arguments as non-options.
269 --- 4.2.15 2011/09/16
271 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
272 searched if absolute filename is given.
274 Fix conv_xslt() error-reporting when stylesheet is not found.
275 (The value of fullpath is meaningless in this situation.)
277 --- 4.2.14 2011/09/07
279 Fix problem in CQL sort node creation: un-initialized memory.
281 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
282 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
283 CQL sortby depending on whether Type-1 or CQL is actually sent to the
286 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
287 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
289 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
290 will make it possible to use both single-character mask (#) and wildcard (?)
291 in CCL . Throw diagnostic for left truncation because that is not supported
294 --- 4.2.13 2011/09/01
296 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
297 cases using escapes (\-sequences) and masking.
299 PQF parse fix: A trailing backslash followed by end-of-string (\0)
300 would result in a read one byte beyond string.
302 rpn2ccl may use Z39.50 masking for terms (t=z).
304 ICU check fix. Don't include library -lCrun on Solaris, unless present.
306 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
307 not --cppflags (which seeems like an error in icu-config).
309 --- 4.2.12 2011/08/27 RPM package only
311 cql2ccl: fix conversion of terms: operator characters were not
314 --- 4.2.11 2011/08/25 RPM package only
316 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
317 CCL parser will map both # and ? to their regular expression
318 quivalents (. and .*).
320 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
321 of reserved CQL characters.
323 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
324 is, so that they are passed through.
326 --- 4.2.10 2011/08/24
328 ZOOM SRU mode: more aggressive re-connect.
330 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
331 made available as a utility function, declared in <yaz/logrpn.h>
333 rpn2cql_structure() supports proximity nodes (except that the Type-1
334 proximity node's "exclusion" binary is ignored, as there is no way to
335 express that in CQL). Fixes bug #4564.
339 Fix SEGV that could occur if set command of zoomsh was given without
340 value (2nd argument).
342 Fix SEGV that could occur if unsupported transport was given for
343 COMSTACK - say https (when SSL was unavailable).
345 Build yaz-url on Windows too.
349 New utility to get web content. Header is url.h. A command line tool
350 yaz-url is part of the distribution and packages.
352 Fixes for SSL COMSTACK (when gnutls is in use).
354 New functions yaz_base64{encode,decode}. Header is base64.h.
358 ZOOM C includes HTTP response buffer as additional info if it fails
359 to decode the SRU response.
361 Make wrbuf_json_puts available.
365 zoom: throw diagnostic for invalid value for option "sru". Before a
366 bad SRU request was sent.
368 Adding new utility wrbuf_vp_puts.
370 Add cclxmlconfig.obj to win/makefile. It was missing completely.
374 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
375 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
376 redirect was used at the same time.
378 MARC line mode decoding: be less picky about length given - first
379 5 digits of header that is.
381 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
383 Changes to decoding of SRU records: a record with recordPacking=xml is
384 modified with a new root element <yaz_record> if the recordData contains
385 multiple children elements. This is to make the record XML parseable
388 RPN to SOLR conversion: encode special characters.
390 Generic Frontend Server: fix uinitialized member, stepSize.
394 Fix a bug in SRU decoding of records.. The database records stored
395 had un-initialized memory, but it would only be seen with yaz_record_render
396 and type_spec="ext" .
398 Fix a bug in ccl_qual_dup introduced in 4.2.3.
402 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
406 Add new utilities to convert from CQL to CCL . These utilities have
407 prefix cql_to_ccl defined in cql.h.
409 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
410 lead to memory heap corruptions when ICU utilities were in use.
414 Make compilation work without Libxml2.
416 yaz-client: remove redundant blanks in display of searchResult-1 term
421 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
422 resulting CQL node (tree) in a new node CQL_NODE_SORT.
424 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
425 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
426 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
427 Note that the CQL sortby spec is only converted when the GFS is already
428 converting from CQL to RPN (cql2rpn element).
430 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
431 specify whether to collapse delimitors or not. The existing nmem_strsplit
432 do collapse (collapse parameter = 1).
434 Windows installer: For NSIS, set InstallDir depending on x86/x64.
436 Rename internal func yaz_use_attribute_create. While non-static, this
437 function is not declared in a public header.
441 Add -lCrun when linking with ICU on Solaris.
443 More quicks character set conversions for OPAC records.
447 fix problem with record_render: records were converted (character set
448 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
452 SRU: add methods for handling DADS SRU-proxy facets.
454 Separate OPAC record character set for ZOOM_record. yaz_record_render
455 allows a character set given as charset=from/opacfrom,to where 'from' is
456 the character set of a bibliographic record, 'opacfrom' is character set
457 of OPAC record and 'to' is the target character set.
461 yaz-client: show may XML format records. Command show followed by 'format'
462 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
465 src/stemmer.c: Avoid using unnamed union. It is not supported by some
468 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
471 Update yaz.spec to operate on both SLES11 / Centos 5.5.
473 RPM: Release includes 'indexdata' name. Use indexdata in release name so
474 this package can be distinguished from other vendors.
476 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
477 as determined by configure
479 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
481 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
482 returns no error and no record, the present request is considered
483 partial (only a subset of the records could be returned by backend), and
484 so it is appropriate to set Present Status to partial-4.
488 Move yaz-config man pages to section 1.
490 More documentation about SOLR.
492 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
493 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
494 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
495 peers on some Linux systems. However, in general that does not work
496 so YAZ can not rely on that to work. Debian changed behavior in this
497 respect from Debian lenny to Debian squeeze (still testing as of Oct
499 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
501 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
505 Fix yaz-config output: echo_source not set correctly by configure.
509 SOLR WebService support for yaz-client and ZOOM.
511 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
513 --- 4.0.12 2010/08/17
515 Z39.50 facet support. Facet specifications are passed for search in
516 other-information with ASN.1 as defined in facet.asn and OID
517 .10.1000.81.5 . Facets are expressed as an Attribute list as known
518 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
519 3 is limit (number of entries to get in response). yaz-ztest returns
520 dummy facets if a client asks for them.
522 --- 4.0.11 2010/07/09
524 CCL fixes: bug 2895 and bug 3539.
526 GR1-display: add comma in display - was removed by mistake in
529 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
531 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
533 --- 4.0.10 2010/06/18
535 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
536 result set from a connection. The result set will be on its own
537 thereafter; no operations on it will perform retrievals from a target.
538 Only cached copies are returned.
540 ZOOM C:fix case for HTTP servers responding with Connection:close.
541 Ensure that if there is a current task it is resumed (like fetching
542 more records in a result set) . Bug #3484.
544 PQF parser: use odr_atoi for Odr_int (not atoi)
546 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
547 values that contain any non-digits are treated as string attributes
548 (previously decoding only checked for leading character ([0-9]). PQF
549 encoding: attribute string values are not surrounded by double-quotes.
553 New utility for managing threads - thread_create.h.
555 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
556 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
557 but YAZ' implementation do.
559 Fixes for yaz_cond-functions on Windows 7.
561 DLL export more symbols.
563 zoomsh: show record do NOT render opac.
565 Remove *.la files from Debian and RPM packages.
569 Debian package libyaz-dev depends on libgnutls-dev again (was
570 removed in YAZ 4.0.6, but due to Libtool it is still needed
571 even though yaz-config do not list libgnutls libs).
573 ZOOM: Use only one WRBUF for returning string results for
574 ZOOM_resultset. Reduces memory usage for ZOOM in general.
576 ZOOM: ZOOM_connection do not use a shared pointer to
577 ZOOM_resultset after ZOOM_resultset is destructed by
578 user. Reverts to YAZ 4.0.4 behavior.
582 record-conv: fix problem with at least one XSL conversion -
583 due to probably incorrect usage of XML XSL documents.
587 Fix yaz-config for static mode and the use of SSL (gnutls).
591 Forward decl timeval struct in mutex.h and gettimeofday.h.
593 yaz-config: fix 'static' mode linking.
597 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
598 are wrappers for pthreads or Windows. For Windows these are put in
599 a separate DLL: yaz_cond4.
601 libyaz.la (whole source) is compiled with thread. If thread support
602 is enabled enabled, all source of YAZ is compiled with treading support.
603 This allows core utilities such as yaz_log to use thread facilities.
604 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
605 thread utilities. This commit moves mutex utilities (mutex.c) from
606 libyaz_server.la to libyaz.la.
608 yaz-json-parse displays leading text until error.
612 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
613 patch from Giannis Kosmas.
615 SRU: no longer URL encode SRU database. The URL for an SRU server is
616 a URL and such is alreeady encoded - at least when given with leading
617 http:// or https://. This reverts behavior to YAZ 3.0.50.
619 Support for new MARC XML notation TurboMARC which like MARCXML is a
620 complete representation of MARC/ISO2709.. This one, however, is more
621 compact and allows for faster processing with XSLT. TurboMARC can be
622 used in the marcdisp.h API, from the yaz-marcdump utility and from
625 yaz-ztest can be configured - via the database - to perform certain
626 delays when it performs operations search, present and single record
627 fetch. This allows testers to make yaz-ztest act as a real or even slow
628 Z39.50 server. Refer to the yaz-ztest man pages for details.
632 wrbuf_destroy allows NULL WRBUF passed to it.
634 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
636 Add ZOOM_connection_close.
638 No fixed size buffers for ZOOM shell - bug #3257.
640 tstodr: make it work on s390 platform.
642 New icu iterator-functions. The new icu_iter-functions makes it possible
643 to use ICU chains from many threads.
645 yaz-client: better syntax check for show command.
649 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
652 New simple local-file XML include facility which allows file glob-patterns.
653 Refer to yaz/xml_include.h.
655 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
658 ZOOM_record_get supports new parameter "format" which makes it format XML
661 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
662 JSONText in ECMA-262) is JSONValue, not JSONObject.
666 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
667 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
669 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
670 POSIX/Unix builds .so with major version 4.
672 Remove old LOG_-defines from log.h. They have been obsolete and
673 undefined by default for the last 5 years.
675 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
677 GFS: Remove socket (int *fd) from search_rr handler. The socket
678 descriptor ptr is a facility that allowed a search handler to supply
679 a socket which would serve as a callback - when search was complete.
680 This facility has now been in use for years.
682 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
683 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
684 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
685 returns 'const char *' rather than 'char *. The returned string is
686 read-only and should not be modified by applications. COMSTACK cs_close is
687 now a void function - it no longer returns int. No applications check for
688 the value and the implementations has always returned 0.
690 ZOOM: use size_t for scan hit counts and str size. Functions
691 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
692 occ (hit count) and len (string length) are now of type size_t pointer
693 rather than int pointer. This is to be able to represent large hit counts
694 and to also just to use the proper type for string length (strlen result).
696 New JSON parser. Refer to include/yaz/json.h .
698 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
699 Used to be int in some cases. Many wrbuf_-functions used to return an int
700 indicating some length.. These return values were never used. And so they
703 ODR: odr_malloc, odr_total now takes size_t for size.
705 clone_z_type: fix leak; occurred for encoding failures.
707 --- 3.0.52 2009/12/03
709 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
710 bug was introduced in 3.0.51.
712 --- 3.0.51 2009/12/02
714 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
716 tcpip comstack: fix leak for getaddrinfo.
718 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
719 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
720 Decoding of SRU "path" database is performed by private function
721 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
722 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
724 yaz-client: honor base command for SRU. Change when database setting
725 is applied for SRU and ensure it is kept when a connection is reset.
726 Change also the way errors are displayed or SRU (decoding of packages).
728 --- 3.0.50 2009/11/02
730 Add support for extra request / response data for SRU codecs and GFS.
731 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
732 for extra data response buffer and length. For the GFS, both request
733 and response data (XML) is carried in extra_args and extra_response_data
734 for the search handler. Patch by Ko van der Sloot.
736 ZOOM: For queries that cannot be converted to the specified rpnCharset,
737 ZOOM now returns a diagnostic on the client-side ('invalid query' /
738 10010). This fixes bug #2113.
740 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
741 cmdfile included a 'quit' command that would result in a memory violation.
743 --- 3.0.49 2009/10/01
745 Make a number of functions defined in xmlquery.c static. These have
746 never been declared in a public header file (yaz/xmlquery.h) and was
747 made public by mistake.
749 Improve speed of character conversions (iconv utilities). This makes
750 conversions from MARC-8 faster.
752 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
753 unless type desired is "raw". This will prevent type "xml" from
754 returning ISO2709 .. Which obviously can not be XML parsed.
756 Fix memory leak in ZOOM that would occur if option apdulog was used
757 on a re-used connection.
759 Frontend server logs HTTP requests.
761 Frontend server now sends Z39.50 close when it times out (sesssion has
762 been idle for too long). Versions 2.0.30 and earlier also sent close.
763 But due to a mistake this was disabled in all versions after that, i.e.
764 the server would just close the socket immediately.
766 yaz-client emits a better message when receiving an unrecognised
767 userInformationField.
769 Skip zero-length subfields when decoding ISO2709. This rare case happens
770 if a record has two FS characters in a sequence. Without this patch
771 there would be a reference beyond char array in using_code_len fragments
774 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
776 --- 3.0.48 2009/08/28
778 The show command offered by the zoomsh command now takes a 3d optional
779 parameter type which is what is passed to ZOOM_record. If the type
780 argument is omitted, "render" is used.
782 RPN to CQL conv may use USE string attributes (bug #2978).
784 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
786 --- 3.0.47 2009/07/08
788 Function yaz_xml2query allows a diagnostic element in the PQF XML
789 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
790 code and additional info respectively.
792 The BER BOOLEAN is now the integral type Odr_bool which still happens
793 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
794 typedef'd to Odr_int. This is still an integral 'int', but it may be
795 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
796 ASN-1 compiler as well as programs has been updated to use the new types.
798 --- 3.0.46 2009/06/08
800 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
801 only the bibliographic record was rendered. For type=opac, an OPAC
802 record is only returned if it is present.
804 iconv: small fix for encoding of advancegreek.
806 yaz-client: avoid double display of SRU/SRW records (bug #2798).
808 yaz-client: option auto_reconnect=on really reconnects.
810 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
812 server: avoid null ptr ref for for yaz_poll errors.
814 build: fix RPM build for RHEL 5.3.
816 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
818 --- 3.0.45 2009/03/31
820 Fixed bug #2709: TCP connect returns Invalid argument.
822 Fixed compilation for mingw.
824 Honor charset for raw records (ZOOM_record_get).
826 Fixed use of errno for threaded mode that was seen on Solaris 10.
828 Fixed argument passing with blanks in value for Windows Service.
830 Disable YAZ' own log rotate by default (no 1 GB limit).
831 The variable l_max_size which specifies the log file limit is set to 0
832 (DISABLED): This is due to the fact that YAZ is most often deployed using
833 logrotate. Also YAZ can not perform log rotate because of unsufficient
834 permissions (setuid).
836 --- 3.0.44 2009/02/17
838 List supported encodings in man page for yaz-iconv.
840 Fixed missing SSL libs for --libs output
842 Re-established OID record syntax application-xml. Nobody should use it
843 but we don't want to change soname because of this symbol being absent.
845 --- 3.0.42 2009/02/02
847 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
849 Added member named_result_sets for init handler struct for the GFS. This
850 allows a server to disable named result sets.
852 Removed OID record syntax application-xml.
854 Added support for rule-based transliterator for ICU wrapper of YAZ.
856 Fixed bug #1902: yaz-icu XML output.
858 Make YAZ checks Emacs friendly.
860 BITSTRING value shows value. Bug #2346.
862 ISO2709 decoding: skip control characters from indicator data.
864 Omit sort key by default in yaz-icu's output.
866 Allow combined single char options (again) for YAZ' options function.
868 Utility yaz-marcdump got option to display YAZ version (-V).
870 Allow YAZ to use ICU 3.4.
872 Added new ICU test case which illustrates removal of diacritics.
874 --- 3.0.41 2008/12/29
876 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
878 --- 3.0.40 2008/12/29
880 For configure, using option --without-xml2 also disables Libxslt/Libexslt
883 Fixed bug #2352: yaz-marcdump crashes for certain record.
885 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
887 Added support for Danmarc2 to UTF-8 conversion.
889 Added support for ISO5426 to UTF-8 conversion.
891 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
892 implementation version.
894 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
896 --- 3.0.38 2008/11/10
898 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
899 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
901 ZOOM C now interprets databaseName option for ZOOM connection as path
904 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
906 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
908 Dummy Libxml2 types no longer defined in headers of YAZ'.
910 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
913 --- 3.0.36 2008/09/26
915 Various ODR chapter fixes.
917 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
919 Added missing source for Windows compilation, mutex.c.
921 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
923 For SRU connections in ZOOM all records up to "count" are now fetched.
925 Fixed crash in generic frontend server (and yaz-ztest) which occurred
926 in Windows due to bad error handling for Libxml2.
928 Added facility for sending arbitrary records (ASN.1 any) using
929 ZOOM C's Extended service update. Patch by Sam Reynolds.
931 New options for ZOOM C's connection, logapdu which makes ZOOM log
934 --- 3.0.34 2008/06/18
936 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
938 --- 3.0.32 2008/06/12
940 Fixed memory violation that could occur when decoding UTF-8. This bug
941 was only present in 3.0.30 of YAZ.
943 --- 3.0.30 2008/06/06
945 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
946 GNU TLS is used by default (if found).
948 yaz-ztest returns OPAC records if a client asks for OPAC.
950 Improved speed of MARC-8 encoding.
952 Added support for lossy and loss-less MARC-8 encoding.
954 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
956 Added new Windows Service wrapper (sc).
958 yaz-client's itemorder command may now send a file.
960 Fixed yaz-marcdump to allow the use of NS prefix for record element.
962 Added new function yaz_log_xml_errors.
964 Allow (but warn) unknown XML attributes in MARCXML parsing.
966 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
968 The UTF-8 to MARC-8 conversion now uses a different set of characters
969 for Greek symbols. Bug #2120.
971 --- 3.0.26 2008/02/21
973 Added yaz_daemon (daemon.h).
975 Fixed bug #2068: pkg-config trouble
977 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
979 --- 3.0.24 2008/01/28
981 Document --with-xml2 option.
983 Added OPAC XML XSD (etc/opacxml.xsd).
985 Allow glob mask for name attribute in retrieval element for the
986 generic frontend server's retrieval facility.
988 Changed yaz_poll_poll to return yaz_poll_except for all returned events
989 except POLLIN/POLLOUT.
991 Fixed error handling in cs_listen. Bug #2037.
993 --- 3.0.22 2008/01/20
995 Fixed version in yaz/yaz-version.h.
997 Fixed bug #2027: Crash when closing connection.
999 Changed configure so that ICU support is only enabled if only ICU
1000 and Libxml2 is available (because the ICU chain is XML based).
1002 --- 3.0.20 2008/01/15
1004 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1005 is built. Only this DLL depends on the ICU runtime.
1007 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1008 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1010 Changed license of CCL module to 'Revised BSD'. After consultation with
1011 remaining members of the original EUROPAGATE consortium, we are re-issuing
1012 the CCL module without a separate license. The software was developed by
1013 Index Data as part of a research project. The special license was included
1014 to help feed usage information back to the project consortium to support
1015 project evaluation. At this time, the project consortium has long-since
1016 disbanded, and the majority of the original principals have retired. At the
1017 same time, we have significantly modified the software during the following
1018 years, to the point where very practically no original code remains. To
1019 simplify re-use of the software, we have contacted those members of the
1020 consortium who could be reached, and agreed to re-issue the module as a
1021 proper part of the YAZ package.
1023 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1025 CQL closer to being version 1.2 compliant. CQL also allows free-form
1026 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1029 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1030 bug could make Extended services handling crash in the ZOOM layer. This
1031 bug was only present in YAZ 3.0.18.
1033 --- 3.0.18 2007/12/19
1035 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1038 yaz-marcdump reads and writes collection wrapped records.
1040 Handle OPAC for record conversion module.
1042 Fixes for ICU wrapper.
1044 Allow ICU libs to be controlled with --with-icu .
1046 --- 3.0.16 2007/11/12
1048 Added yaz_poll which is a wrapper for select/poll. When poll is available
1049 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1050 sockets to be in use.
1052 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1053 functionality through an XML based configuration (ICU chain). This system
1054 is useful for search facilities such as Pazpar2 and Zebra that needs to
1055 perform tokenization of indexed material. The ICU code in a separate
1056 library libyaz3_icu.a.
1058 Added HTTP tunnel facility for COMSTACK, bug #1752.
1059 This is a facility that allows a Web proxy, such as squid, to tunnel
1060 Z39.50 traffic. This facility is "transparent" to must applications
1061 using YAZ. It's enabled by using pseudo transport connect: followed by
1062 the proxy address, followed by command, then follwed by he regular
1063 "virtual" addresss. For example,
1064 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1066 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1068 --- 3.0.14 2007/09/21
1070 Fixed bad memory reference in ZOOM_record - cuased by member not being
1071 initialized. This was a problem only in YAZ 3.0.12.
1073 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1074 fields were not removed.
1076 Changed the way C code is generated from codetables.xml. Made a MARC-8
1077 conversion trie for each characterSet section rather than codeTable.
1078 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1079 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1081 --- 3.0.12 2007/09/12
1083 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1084 from ZOOM_record_error).
1086 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1088 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1090 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1092 Better SRW-to-Bib-1 diagnostic mapping.
1094 ZOOM C and yaz-client announces SRU version 1.2 by default.
1096 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1099 Fixed in yaz_sru_decode to allow other version than 1.1.
1101 --- 3.0.10 2007/08/22
1103 Added support for SRU scan for ZOOM.
1105 Added support for the use of the older versions or Extended Service
1106 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1107 set to the version , 1=first, 2=second, 3=third. The third version is
1108 what ZOOM C has used so far. And that, obviously, is the default.
1110 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1111 therefore in Zebra and in SimpleServer-based applications). The new
1112 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1113 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1114 which is passed into the back-end search callback function.
1116 Added support for HTTP Basic authentication in clients: the SRU/W
1117 codec encodes the username/password elements of the PDU structure
1118 appropriately, and these may be set using the "user" and "password"
1119 options in ZOOM-C applications (the same options that are used for
1120 Z39.50 authentication).
1122 --- 3.0.8 2007/06/25
1124 Fixed bug #1208: SSL appears to be broken in ZOOM.
1126 Fixed bug #1206: Libxml2 include path weirdness.
1128 Added oid_name_to_dotstring.
1130 Allow elementSetName to be specified for ZOOM C record update.
1132 Allow waitAction to be specified for ZOOM C based for Extended Services.
1134 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1135 syntax OID. Bug introduced in YAZ 3 series.
1137 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1139 --- 3.0.6 2007/06/06
1141 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1142 directory. yaz-client now reads commands from file given by option -f
1143 if specified; then tries to read .yazclientrc in current directory.
1144 Failing that, it reads .yazclientrc from user's home directory.
1146 Added support for correlationInfo Note and ID for Record Update via
1149 Added yaz-client command querycharset which specifies character set for
1150 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1151 (termListAndStartPoint).
1153 Charset ISO5428:1984 is an alias for ISO5428-1984.
1155 Implemented a way to perform scan in a result set using Z39.50. This
1156 is achieved by attaching the result set name in the characterInfo
1157 (type InternationalString) of OtherInformation in the Scan Request PDU.
1158 The result set is identified in the otherinformation by the new OID:
1159 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1160 This allows for scan in result set and faceted search . Zebra did some
1161 of this in the APT term using attribute type 8 and value being result
1162 set. Using the OtherInformation approach for this is cleaner and easier
1163 to work with in proxies and the like. This facility can be used in
1164 yaz-client using new command setscan which takes a result set as first
1165 argument, start position (APT) as second.
1167 Changed decoding of SRU XML packed records to deal with servers that
1168 have recordData with XML data with multiple root nodes. Also make
1169 comparison for recordPacking case insensitive. Again, one server
1170 returns "XML" where others return "xml".
1172 For SRU responses allow Content-Type application/xml as well as text/xml.
1174 --- 3.0.4 2007/05/21
1176 Fixed bug in character set conversion of BER strings. Bug introduced
1179 --- 3.0.2 2007/05/08
1181 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1183 For OID class, use oid_class consistently.
1185 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1188 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1189 character set for bibliographic information interchange". By Giannis Kosmas.
1191 Added documentation on new OID API.
1193 --- 3.0.0 2007/05/02
1195 Changes to generic frontend server interface: added new member
1196 'query_charset' for bend_initrequest structure. A backend init handler
1197 should set this member to its native character set for query terms.
1198 When defined, the frontend server logic will announce this character set
1199 to a client if the negotiationModel bit is set by the client. All server
1200 implementors are encouraged to specify this. If a backend server does not
1201 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1203 Added CCL utility to remove terms (stop words) from resulting RPN
1204 tree. This is handled by functions with prefix ccl_stop_words_ .
1206 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1207 terms in RPN queries.
1209 Clean-up the CCL API. Moved some internal structures from ccl.h to
1210 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1211 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1212 This is replaced by ccl_parser_find_str which takes a string instead.
1214 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1215 libyaz.la is the core of YAZ except the generic frontend server and
1216 does not depend on POSIX threads anymore. libyaz_server.la is the
1217 generic frontend server facilities and uses POSIX thread functionality
1218 if available. The libyaz.la no longer depends on POSIX threads because
1219 the number of global structures is limited. NMEM no longer re-uses blocks
1220 between threads ; it simply free's memory immediately but allocates in
1221 "large" chunks as usual. We don't expect any performance penalties
1222 because of this. The yaz_log system is still using a global log_level so
1223 caution must be taken when modifying it with yaz_log_init_.. +
1224 yaz_log_mask_str. This, however, should not cause any trouble because
1225 these functions are called during initialization of application code
1226 anyway. `yaz-config --libs server` returns libs for server applications;
1227 `yaz-config --libs` returns libs for non-server applications.
1229 New OID database - with public definitions in oid_db.h. Removed old OID
1230 database including the head oid.h and definitions such as enum oid_value
1231 and struct oident. The new OID database uses the same string names as
1232 before but the 'protocol' is gone. There are now only two representations
1233 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1234 converts from string to OID; functions with prefix yaz_oid_to_string
1235 converts the other way.
1237 Change to emit_term() in CQL-to-PQF query translation: when a term has
1238 the /regexp relation modifier, do not process it for leading and
1239 trailing "^" and "*", which have quite different meanings in regular
1242 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1243 write handlers no longer carries a 'last' parameter. This will make
1244 yaz_iconv flush "less" characters. A flush is performed by call to
1245 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1247 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1248 removed, because function yaz_query_to_wrbuf does the same.
1250 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1251 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1253 Deprecated MARC utility functions removed.
1255 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1258 Branch split: YAZ_2_1_55_branch
1260 --- 2.1.54 2007/03/16
1262 Fix to ZOOM-C so that transparent reconnection is properly handled on
1263 connections that are in asynchronous mode.
1265 Fixed compilation on OpenBSD 4.0.
1267 Large strings in GRS-1 records are now properly displayed in yaz-client.
1269 Added character conversion support for "advancegreek"; based on patch from
1272 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1273 sequence is met. Before the error was not set so it would be unknown.
1275 Adjust yaz-marcdump MARC reader so that it skips until record separator
1278 --- 2.1.52 2007/03/07
1280 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1281 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1282 fd_set structure used as a bitmask for the FDs to be selected on.
1284 Using ACX_PTHREAD macro to check for POSIX threads.
1286 Fixed have-vsnprintf check.
1288 --- 2.1.50 2007/02/23
1290 Fixes for configure on BSD. Bug #900.
1292 Added snprintf/vsnprintf wrappers for systems that don't have
1293 limits (heavens forbid).
1295 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1296 created before all previous tasks were completed and removed from the
1297 task queue, the new task could be removed by a mistake.
1299 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1301 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1303 Fixed bug #832: Problem with MARC/charset in yaz-client.
1305 Fixed bug #668: save command line history for yaz-client.
1307 Fixed bug #830: pkg-config support.
1309 --- 2.1.48 2007/01/23
1311 Extended ZOOM result set options with two options that may be read by
1312 a client: resultSetStatus and presentStatus with values as specified for
1314 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1316 Fixed bug #827: Using SSL fails on Debian etch.
1318 Fixed bug #826: Weird looking chars for set of MARC records.
1320 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1321 that is treated as an ItemOrder with itemRequest being an XML document
1322 external. The value of "doc" is the content.
1324 Extended the GFS search facility. New member of bend_search_rr
1325 'estimated_hit_count' signals that hits is known to be an estmate
1326 (higher or lower than real hit count). New member 'partial_resultset'
1327 signals that the search was partial (hit count is lower or equal than
1328 real hit count). For Z39.50, the information is stored in resultSetStatus
1329 member of SearchResponse APDU. For SRU, the information is signalled
1330 via SRU diagnostic 59: "Result set created with valid partial results
1333 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1335 --- 2.1.46 2007/01/13
1337 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1339 Added ZOOM_connection_peek_event.
1341 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1342 the following new functions:
1343 ZOOM_event_nonblock, ZOOM_connection_process,
1344 ZOOM_connection_get_{socket,mask,timeout},
1345 ZOOM_connection_fire_event_{timeout,socket}.
1346 The existing blocking event handler, ZOOM_event, is a wrapper for the
1347 + blocking ZOOM_event_sys_{poll,select}.
1349 Implemented function ccl_xml_config which parses XML version of CCL
1350 configuration (bug #798).
1352 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1354 Added timings utility (yaz/timing.h)
1356 --- 2.1.44 2007/01/03
1358 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1361 Fixed bug #779: Rotation of apdu.log fails.
1363 Fixed for character set conversions:
1364 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1365 Honor G1 set in MARC-8 decoding.
1367 --- 2.1.42 2006/12/17
1369 Fixed bug #775: char conversion does not handle Alternative UTF-8
1372 Implemented function yaz_marc_read_line which parses MARC line format
1373 records. There is a wealth of formats out there. So far, this function
1374 reads line records produced by yaz_marc_write_line.
1376 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1377 more generic and easier to remember(!) options: -i format and -o format
1378 which specifies input format and output format respectively - where
1379 format is one of "marc", "marcxml", "line", "marcxchange".
1381 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1382 does not print anything except warnings for records.
1384 For yaz-marcdump, added support for MARC split into files (-s) with a given
1387 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1388 spec, at http://www.loc.gov/standards/sru/record-update/
1389 This has changed the binary layout of the following structs:
1390 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1391 bend_update_rr . Patch by Ko van der Sloot.
1393 Added GFS utility function bend_assoc_is_alive which returns 1 if
1394 association is still alive (client is connected); 0 otherwise (client
1395 closed connection). This allows busy servers to stop working for
1398 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1399 been a separate piece of software. This version of ziffy has been modified
1400 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1402 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1404 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1405 Client code may now interrogate options such as "init_opt_sort" to
1406 find out whether the server claims to support various options.
1408 --- 2.1.40 2006/11/27
1410 Added utilities yaz_{set,get}_esn to set/get element set name from
1413 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1414 of YAZ and has been so since YAZ 2.1.10.
1416 Implemented ZOOM_record_error which returns error information for
1417 record (surrogate diagnostic).
1419 --- 2.1.38 2006/10/31
1421 Updates for SRU Update by Ko van der Sloot:
1422 1. Changed name from "operation" to "action"
1423 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1424 versions in the code, marked as 'backward compatible'.
1425 3. Added diagnostics for SRU Update.
1427 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1429 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1431 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1433 For GFS, fixed problem with SRU diagnostic 'First record position out of
1434 range' being issued for 0 hits.
1436 zoomtst10 part of Windows Build.
1438 --- 2.1.36 2006/10/13
1440 Implemented yaz_filepath_comp which splits a path into file path
1441 components (required by Zebra 2.0.3+).
1443 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1444 BSD inspired license until now so this should not have any real impact on
1445 anybody. See http://www.opensource.org/licenses/bsd-license.php
1447 Fixed bug #687: Missing log lines.
1449 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1452 Fixed bug #689: SRU diagnostics to be added.
1454 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1455 whether a connection is idle (no more work do do).
1457 --- 2.1.34 2006/10/04
1459 Change type of optval from long to int for invocation of setsockopt with
1460 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1462 Added support for specifying the max log file size for the Generic
1463 Frontend Server. The size is given with option -r.
1465 --- 2.1.32 2006/09/21
1467 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1469 --- 2.1.30 2006/09/17
1471 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1474 Fixed bug in Generic Frontend Server that could cause a server to stop
1475 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1477 For the generic frontend server, the maximum record size is used as maximum
1478 size of incoming packages (SRU + Z39.50). The value until was previously
1479 only used in Z39.50 Init negotiation and, later, in a session controlled
1480 sizes of records returned. This is controlled using -k option. It can be
1481 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1483 --- 2.1.28 2006/09/04
1485 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1488 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1490 New option for yaz-marcdump -lpos=value which allows setting a portion
1491 of MARC header to a certain value.
1493 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1495 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1496 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1498 --- 2.1.26 2006/08/15
1500 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1503 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1505 --- 2.1.24 2006/08/08
1507 Fixed MARC ISO2709 encoding routines to deal with character set
1510 Minor changes to GFS logging. Database included in search request log
1513 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1514 cached/multiple records.
1516 Shared libraries are built by default on Unix+configure.
1518 Changed cql2pqf transformation to use a different evaluation order. The
1519 new order is: always, relation, structure, position, truncation, index
1520 and relationModifier. Old order was: always, relation, relationModifier,
1521 structure, index, position, truncation. Note that the the latter ones
1522 override former ones for identical attributes.. The new scheme means that
1523 it is possible to override any existing attribute with a relationModifier.
1524 And also that it is possible to override everything for the index rule
1525 (except the ones listed in relationModifier). No order is perfect but this
1526 one, we believe, covers more real cases.. The "always" should have been
1527 called "default", since the attributes there can be overridden with all
1530 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1531 compilation phase, but also for yaz-config --cflags output. This allows
1532 us to have public headers with Libxml2 stuff in them . It should also,
1533 eventually, make Libxml2 checks redundant in packages using YAZ, such
1536 --- 2.1.22 2006/06/15
1538 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1539 stored in uri, message and details.. Previously diagnostics were stored
1540 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1541 compatibility.. but he's probably the only one affected, so.
1543 Added support for CCL, compiled on the client side, in ZOOM-C. This
1544 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1545 input; the resulting query objects can be used for for searching with
1546 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1548 YAZ' configure searches for OpenSSL by default.
1550 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1551 SL_CTX_use_certificate_file. See
1552 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1553 for more info. Thanks to Ko van der Sloot.
1555 --- 2.1.20 2006/06/02
1557 Bug #600: SRU GET, POST support for yaz-client. Introduced
1558 command 'sru' which selects method SOAP/GET/POST.
1560 Allow missingValueAction to be specified for the sortspec string -
1561 function yaz_sort_spec. By default, the missing value action is null.
1562 Use ! to specify "abort". Use = followed by stringvalue to specify default
1565 Ensured that Present-handler (if defined) is called in GFS before any call to
1566 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1567 searchRetrieve requests.
1569 Documentation for YAZ is now based on the Docbook XML/XSLT using
1570 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1571 is no longer depending on jade/openjade or docbook-to-man scripts.
1572 PDF is no longer part of the distribution - but can optionally be
1573 made using DSSSL/jadetex or FOP.
1575 Added retrieval handling support in Generic Frontend Server to support
1576 conversion between MARC/XML as well as XSLTtransforms. See
1577 etc/yazgfs.xml for an example.
1579 Added Authentication support to Generic Frontend Server in SRU
1580 mode. Authentication using HTTP Basic is supported, as is the use
1581 of 'x-username' and 'x-password' parameters in the request itself.
1583 Added support for a new character set MARC8s identical to MARC8 except
1584 that it converts combined characters to single Unicode characters in the
1585 Latin-1 range (when possible).
1587 --- 2.1.18 2006/04/24
1589 ASN.1 compiler 0.4: generates brief Doxygen file header for
1590 generated .h/.c files.
1592 Utility yaz_iconv now supports conversion to MARC-8.
1594 New facilities for the MARC module. The reading - and writing of
1595 content are separate methods for the yaz_marc_t handle. The following
1596 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1597 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1598 format). Write functions have prefix yaz_marc_write_.. The existing
1599 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1600 available. Removed support for OAI-MARC and simplexml (not the
1601 simplexml from PHP5).
1603 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1604 to be returned for this connection.
1606 --- 2.1.16 2006/03/31
1608 Allow multiple languages and charsets to be specified with
1609 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1610 negcharset iso-8859-1,utf-8
1612 Translation of proximity nodes from CQL into PQF now works.
1614 Moved to automake 1.8, 1.9.
1616 Added function yaz_log_set_handler which allows a log handler to be
1617 installed. This handler will be called for all log messages. Output
1618 to file is also produced; but that can be disabled by passing NULL
1619 fname to yaz_log_init_file.
1621 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1623 For SRW (including GFS), accept application/soap+xml as content-type
1626 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1627 produces NO stylesheet reference even if a default stylesheet is specified
1630 --- 2.1.14 2006/03/14
1632 Updated Windows package to include yazd.dll + yazd.lib for the
1633 Development component.
1635 If the environment variable YAZ_LOG is set, then it is used as a
1636 string indicating the default level of logging to use if not
1637 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1638 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1639 used as before. So, for example, to omit warnings from YAZ logging,
1640 export YAZ_LOG=-warn
1642 cql_transform() now map structure and other attributes before indexes,
1643 so that index-specific structures and other attributes can override
1644 defaults. So now a combination of mapping specifications such as:
1646 index.dc.date = 1=date-modified 4=5
1647 does the right thing.
1649 cql_transform() now also respects the "always" mapping specification,
1650 which establishes an initial set of attributes to be used for all
1651 terms except where overridden by more specific attributes associated
1652 with the index, relation or modifier.
1654 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1655 which mode to use; one of "post", "get" or "soap" (SRW, default).
1657 Fixes for yaz_iconv routines: changed trie-based character set conversions
1658 to use only non-negative values for bit fields due to Sun's C compiler not
1659 supporting negative values.
1661 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1662 sequences where not read correctly. Fix by Rustam Usmanov.
1664 Updated win/makefile to use options, settings which makes things
1665 compile with VS C 2005.
1667 --- 2.1.12 2006/02/01
1669 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1671 In ZOOM socket code, use select instead of poll on MacOSX.
1673 ZOOM-C now support client-side compilation of CQL into RPN that is
1674 sent to the server, enabling CQL to be used against all Z39.50
1675 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1676 ZOOM_query object, and submit it using ZOOM_connection_search().
1677 The CQL-to-RPN translation uses a configuration file, the name of
1678 which must be specified in the Connection's "cqlfile" option.
1680 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1681 function, which takes as its start-term parameter a ZOOM_query object
1682 (which may have had either CQL or RPN set into it).
1685 --- 2.1.10 2005/11/29
1687 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1688 GFS to support this as well. Backend handler, bend_srw_update, does the
1689 update work. Code contributed by Ko van der Sloot.
1691 Allow retrieval of Search Result-1 information in ZOOM by the use of
1692 options that are attached to a result set. ZOOM documentation updated
1695 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1696 UTF-8 conversion. Patch by Raj Patel.
1698 Added option -m to GFS to control formatting of timestamps in log file.
1700 Added 'exit' as synonym for 'quit' in yaz-client
1702 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1703 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1704 for the new members. Patch by Ko van der Sloot.
1706 Added support for SRU POST. It is supported for content-type
1707 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1709 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1710 Instead make the library libyaz.la multi-threaded. Threading as a whole
1711 can still be disabled by configure option --disable-threads. Previosly,
1712 with older GLIBCs there were problems with MT libs under Apache. This
1713 has now been fixed a long time ago.
1715 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1718 CQL module modified to be case insensitive for relations/indexes/operations.
1720 Fixed bug in CQL transform code: incorrect value relationModifieder
1723 Added 'show all' command for yaz-client which retrieves all results
1726 Added new yaz-client, xmles, which takes a (private) OID and
1727 a document to be sent as an extended service request.
1729 Describe new yaz-client commands wait_response and set_auto_wait.
1731 Increase TCP/IP listener backlog from 3 (which I am guessing was
1732 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1733 that the socket will queue as many incoming connections as it's able
1734 to handle ongoing connections. In other words, it will never now
1735 refuse a connection that it would be able to handle merely because
1736 it's not got around to accepting() enough of the pending connections
1737 yet. This is the behaviour anyway under Linux, where the listen()
1738 argument is ignored; but not under BSD and on systems such as
1739 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1740 YAZ-based servers should now be uniform across operating systems in
1743 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1744 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1745 This allows yaz-marcdump to read large MARC batches (>2 GB).
1747 Modified all YAZ source files - except the source which is auto-generated
1748 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1751 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1752 corresponding to the existing *_setl() function. These allow option
1753 values containing arbitrary valuues.
1755 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1756 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1757 except that it returns an indicator of whether or not the sort
1758 criterion was accepted (0 for OK, -1 for invalid).
1760 --- 2.1.8 2005/06/07
1762 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1763 MARC output rather than returning "new" buffer.
1765 yaz-client warns about unknown init options.
1767 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1769 --- 2.1.6 2005/05/24
1771 Added support for SRW sort in Generic Frontend Server. Patch
1772 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1773 sortKeys - or NULL if none is provided.
1775 Fixed bug #307: It was impossible to specify indefinite/no timeout
1776 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1779 Added support for multiple languages and charsets to be specified in
1780 ZOOM. Each charset/language is separated by a blank. If negotiation is
1781 in effect in init-response, Option
1782 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1783 Code based on patch by Vasiliy Osadchuk.
1785 Fixed bug #306: infinite recursion that occurred when calling
1786 yaz_log_level_init as the first call (before other log level or
1789 Fixed bug in scan handling in front end server: if preferred-Position-In-
1790 Response was non-present, a NULL pointer referece was performed.
1792 --- 2.1.4 2005/04/26
1794 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1795 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1796 now defined for all those error codes. So instead of putting 109 in
1797 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1798 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1800 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1803 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1805 Program yaz-client now exits and produces an error message if multiple
1806 Z39.50 servers are specified on the command line (none or one allowed
1809 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1812 --- 2.1.2 2005/03/16
1814 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1816 Fixed bug #272: Preserve spacing for CCL terms.
1818 --- 2.1.0 2005/03/14
1820 Added support for virtual hosts and multiple backend servers for
1821 the YAZ frontend server. The configution is XML based and
1822 support specificition of CQL to RPN mappings and explain information.
1823 See section "Virtual Hosts" in the YAZ manual.
1825 Extended OPAC display utility. OPAC display utility renders
1826 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1827 to supplement yaz_marc_decode_wrbuf.
1829 Fixed a bug in MARC decoder that could caused it to crash for some
1830 invalid MARC records. More diagnostics and warnings where added in
1831 XML output (warnings, etc are stored in comments).
1833 --- 2.0.34 2005/02/08
1835 Fixes for UNIX domain sockets. Bug #261.
1837 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1839 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1840 Added yaz_marc_subfield_str which defines subfield lead string which is
1841 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1842 yaz_marc_endline_str which defines end of fields string used in
1843 YAZ_MARC_LINE format. Default string is newline.
1845 Experimental support for MarcXChange. This format can be produced
1846 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1847 http://www.bs.dk/standards/MarcXchange.xsd
1849 Added yaz-client commands scansize that sets maximum number of
1850 entries to be returned by scan.
1852 --- 2.0.32 2005/01/11
1854 Added support for SRW scan in yaz-client and Generic Frontend Server.
1856 * Added whereInList member to SRW Scan Term.
1858 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1860 Fixed NMEM system to return aligned blocks on the smallest boundaries
1861 that are suitably aligned for all possible types on the particular
1862 architecture YAZ is being built for.
1864 --- 2.0.30 2005/01/04
1866 Fixed numerious warnings that was issued with newer versions of GCC.
1868 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1869 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1872 Make YAZ Generic Frontend Server slightly faster.
1874 Enhance (and reduce) logging for Generic Frontend Server.
1876 Revert YAZ log system so that it flushes every write operation
1877 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1879 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1880 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1881 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1882 will effectively disable old definitions.
1884 --- 2.0.28 2004/11/09
1886 Added yaz_log_time_format which specifies log format using
1889 Added yaz_log_module_level which returns mask for a module. Value
1890 is non-zero mask a if module is enabled; zero if disabled.
1892 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1893 in include/yaz/cql.h.
1895 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1897 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1899 Fixed bug #172: RPM builds does not enable SSL.
1901 Doxyfile.in part of dist. Doxyfile generated by configure.
1903 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1904 are given and the corresponding component does not exist.
1906 Extend CCL documentation in YAZ reference. Describe r=r.
1908 --- 2.0.26 2004/10/01
1910 Fixed MARC->MARCXML conversion to properly deal with
1911 fields, subfields, indicators having non-ASCII characters.
1913 Fixed MARC->MARCXML conversion so that ASCII control characters
1914 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1917 Added YAZ GFS support for conversion from Z39.50 surrogate
1918 diagnostics to SRW surrogate diagnostics.
1920 Bug fix: YAZ GFS did not return schema in explainResponse.
1922 --- 2.0.25 2004/09/30
1924 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1925 now converts recordSchema to elementSetName as well as schema URI.
1927 Fixed bug in COMSTACK that prevented HTTP request packages from being
1930 --- 2.0.24 2004/09/29
1932 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1933 does not require white-space before and after the dash in a range, e.g.
1934 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1937 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1938 due to new GCC removing "redundant" code.
1940 Added yaz-client commands scanpos and scanstep that sets preferred
1941 position and step-size for scan.
1943 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1945 Added CCL utility ccl_qual_buf which parses one or more CCL
1946 spec lines in a buffer.
1948 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1949 of name and value - ignoring empty lines and comments.
1951 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1953 Added odr_get_element_path which returns current element path for an
1954 ODR handle. This utility is useful in error handling or user-defined
1957 Added ODR_PRINT utility odr_set_stream which is is a more generic
1958 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1959 to a write function and pointer to close function. The close function - if
1960 non-NULL - will be called during odr_destroy.
1962 Fixed bug in CCL parser where truncation char was not removed from
1963 right side when truncation=both was in effect.
1965 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1968 --- 2.0.23 2004/08/11
1970 Fix buffer overrun in CQL parser when dealing with proximity (%).
1972 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1973 to UTF-8/UCS conversion is now only based on codetables.xml.
1975 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1977 --- 2.0.22 2004/08/06
1979 Add support for more "commit changes" in ZOOM (uses Extended Services).
1981 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1984 Yet another small fix for configure of SSL.
1986 --- 2.0.21 2004/05/14
1988 Fix SSL libs for configure when --with-openssl=DIR is given.
1990 --- 2.0.20 2004/05/10
1992 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1994 SSL comstack now uses yaz.pem certificate file on server side
1995 by default. Certificate filename can be configured by calling
1996 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1998 Fix bug regarding multiple calls to ZOOM_connection_connect.
2000 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2002 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2003 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2005 ZOOM now allows inspection of X509 peer certificate for verification.
2006 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2008 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2009 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2010 as "modular" but it simplifies things.
2012 Added cs_get_peer_certificate to that returns peer X509 PEM.
2014 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2015 NULL if SSL is unavailable.
2017 Documentation about MARC decoding tools.
2019 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2021 --- 2.0.19 2004/03/30
2023 Rename CHANGELOG to NEWS to follow GNU style packing.
2025 Fix bug with missing initialization of member in init_diagnostics.
2026 This bug affects threaded version of GFS server.
2028 --- 2.0.18 2004/03/20
2030 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2033 Ensure zlib.dll is packed with Windows install.
2035 --- 2.0.17 2004/03/17
2037 Fix encoding of xsd:string to use text instead of CDATA.
2039 Fix endless loop in CQL parser with unbalanced ".
2041 Use a more compact way to store MARC-8 conversion tables.
2043 --- 2.0.16 2004/03/16 Debian only
2045 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2048 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2053 --- 2.0.15 2004/03/01
2055 Another fix for decoding of XML packed records.
2057 --- 2.0.14 2004/02/25
2059 Fixes for Chunked encoding. White space not ignored after length spec.
2061 Update NS and use default NS for SRW diagnostic elements.
2063 --- 2.0.13 2004/02/23
2065 Implement ZOOM_resultset_cache_reset which resets record cache.
2067 Implement ZOOM_resultset_sort which sorts a result set.
2069 Implement chunked HTTP transfer.
2071 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2073 --- 2.0.12 2004/02/16
2075 Added member 'schema' to bend_explain_rr structure so that backend
2076 can specify explain record identifier. Defaults to Zeerex 2.0.
2078 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2080 --- 2.0.11 2004/02/16
2082 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2085 Added init command for yaz-client which sends "extra" init request.
2087 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2088 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2090 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2092 Make ZOOM error code for "invalid query".
2094 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2096 --- 2.0.10 2004/02/05
2098 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2101 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2103 Added option -p <file> to make Generic Frontend Server to write PID file.
2105 Added option -D to put Generic Frontend Server in background on its own.
2107 Make ZOOM C recognize option "password". If unset, "pass" is used
2108 (for backwards compatibility).
2110 Fixed a bug in Generic Frontend Server that could make it crash if a
2111 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2114 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2115 Must be issued before open, in order to be in effect.
2117 --- 2.0.9-6 2004/01/12 Debian/Windows
2119 Make the SRU server more picky WRT unknown params, etc.
2121 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2123 New YAZ client command, options, that sets Z39.50 options.
2125 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2126 options from a string of tokens (one token for each option bit).
2128 Update SRW diagnostic code messages.
2130 --- 2.0.9-5 2004/01/07 Debian/Windows
2132 Handle user defined stylesheet for SRW/SRU.
2134 --- 2.0.9-4 2004/01/06 Debian/Windows
2136 Fix bug in decoding of Content-Length.
2138 --- 2.0.9-3 2004/01/06 Debian/Windows
2140 Fix a bug with decoding of XML packed records.
2142 --- 2.0.9-2 2004/01/05 Debian only
2144 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2146 Fix bug in SRW/SRU diagnostics decoding.
2148 --- 2.0.9 2004/01/05
2150 Fixed bug in Generic Frontend Server which could drop records exceeding
2151 preferred message size. Reported and fixed by Irina Dijour.
2153 Fixed calculation of package size for structured records in Generic
2154 Frontend Server. Reported and fixed by Irina Dijour.
2156 Fixed namespace for SRW/SRU diagnostics.
2158 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2160 --- 2.0.8 2003/12/22
2162 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2163 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2166 CQL changes to reflect recent changes to the specification:
2167 * Documentation talks about context sets instead of index sets.
2168 * Documentation talks about indexes instead of qualifiers.
2169 * The CQL-to-PQF transformer's configuration file now uses
2170 "index.set.name = <attributes>" instead of the old form
2171 "qualifier.set.name = <attributes>". (Both forms are still
2172 understood but the latter is deprecated.)
2173 * CQL terms with no explicit index specified are now interpreted as
2174 cql.serverChoice instead of srw.serverChoice (which of course
2175 behaves exactly the same.)
2177 --- 2.0.7 2003/12/16
2179 MARC conversion can now generate ISO2709 output in another
2180 character set. yaz-marcdump uses this facility if you invoke it
2183 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2184 functions from there can be used from C++.
2186 --- 2.0.6 2003/12/04
2188 Frontend server now transfers memory from decoded packages to stream
2191 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2192 references to show up.
2194 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2195 the ZOOM Abstract API. The older names for the same options are still
2196 also supported for the benefit of old applications.
2198 ZOOM-C supports "implementationId" and "implementationVersion" options
2199 to go along with "implementationName". These allow the user code to
2200 specify identification strings to be sent to servers.
2201 Add OID for the new ExtLite attribute set.
2203 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2204 as requested/supplid by Ere Maijala <ere@atp.fi>
2206 For generic frontend server, reverse the order of
2207 "toolkit-supplied / application-supplied" strings sent as implementationId,
2208 Name and Version. Also, remove the spaces around the slash. This brings
2209 the GFS in line with the behaviour of ZOOM-C on the client side.
2211 Add function ZOOM_scanset_display_term.
2213 yaz-client shows scan displayTerm if present.
2215 Utility yaz-iconv is now installed by default along with the man page
2218 Extend configure check for OpenSSL to use pkg-config where available (such
2221 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2222 server to specify uid/gid/mask for socket using the format
2223 unix:[user=uid,][group=gid,][umask=mask,]file=path
2224 If file= is omitted the existing format is assumed, e.g.
2226 in which case the mask is 0666 (rw for everybody).
2228 Major restructure of YAZ source. All source in libyaz is in src directory.
2229 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2230 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2232 Added man page for utility yaz-marcdump (used to be called marcdump).
2233 yaz-marcdump is installed by 'make install'.
2235 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2236 of incoming package failed.
2238 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2240 Change prototype of odr_perror: add const to message string.
2242 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2244 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2245 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2246 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2247 DNS lookup. There should not be any compatibility problems with this
2248 assuming that blocking=1 or 0 is used.
2250 Fix bad reference in UNIX comstack in function cs_addrstr.
2252 Fix for compilation on AIX.
2254 The generic front-end server (server/seshigh.c) now supports returning
2255 Init diagnostics to the client in User-information-field, in
2256 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2259 --- 2.0.4 2003/09/04
2261 Allow any CQL relation (not just all,any,exact,scr).
2263 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2264 that features the same UI.
2266 Implemented command update0 in YAZ client which is equivalent to
2267 update but uses old of Ext Update ASN.1.
2269 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2270 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2271 Previously no OID was used for this info.
2273 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2274 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2275 returns 'malformed search term' otherwise.
2277 SortResponse member resultCount now set to NULL in sort handler of
2280 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2283 Add three new utility functions for translating OIDs between various
2284 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2285 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2286 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2287 char *oid_to_dotstring(const int *oid, char *oidbuf);
2288 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2290 Reverted modifications for ES Update definition for z_IU0Update
2291 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2292 is back to YAZ 2.0.2.
2294 String value attributes for CCL parser.
2296 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2297 which their FirstSearch server returns in Init responses, sometimes
2298 carrying useful diagnostic information when Init fails. This has the
2299 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2300 "z39.50/oclcui.asn", where its definition is somewhat different from
2301 what OCLC document on their web-site, as required to interoperate with
2304 Support for anonymous authentication in yaz-client. Use the command
2307 * Fix the OID of the Index Data-local "admin" Extended Service from
2308 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2309 the 1000, which indicates a locally-defined OID, was a mistake.
2311 --- 2.0.3 2003/06/20
2313 Fix CCL directive @case handling so that it affects string match for
2314 both CCL keywords and qualifiers.
2316 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2317 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2318 Decoder has been updated with ASN.1 changes as listed in
2319 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2320 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2321 z_IUUpdate, remains unchanged.
2323 ZOOM_record_get may now return a record in a specific character set.
2324 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2325 "from" is the character set of record as returned by target. "to" is
2326 the character set to be returned. If omitted, "to" is UTF-8.
2328 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2330 New ODR utility, odr_getelement, which returns name of element for
2331 which encoding/decoding failed.
2333 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2334 in cases where a required element was omitted.
2336 Bug fix: some MARC8 sequences were not converted.
2338 New ZOOM option "step" which specifies number of records to be
2339 retrieved in one chunk. Used in conjunction with "start" and "count".
2341 SRW support for yaz-client. Use scheme http: to use it, e.g.
2344 yaz-client no longer does (un)intelligent character set conversions
2345 by default. Can be enabled with charset and marc_charset commands.
2347 xmalloc trace fix for 64-bit systems such as DEC alpha.
2349 Solaris 2.6 compile fix.
2351 New function, cql_strerror() translates SRW error codes, as returned
2352 by cql_transform_error(), into human-readable English strings. Used
2353 in yaz-client diagnostics when appropriate.
2355 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2356 converts it into a type-1 query which is sent to the server. This
2357 makes CQL available for use with all Z-servers, as opposed to the tiny
2358 minority that can handle CQL queries themselves.
2360 --- 2.0.2 2003/04/28
2362 New Debian package layout similar to the Redhat Package layout.
2364 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2365 and search result respectively.
2367 --- 2.0.1 2003/04/25
2369 Redhat package is now several packages: libyaz (runtime libraries),
2370 libyaz-devel (development and documentation, and yaz (utility programs).
2371 Package spec file by Morten Bogeskov.
2373 New member 'schema' in struct bend_fetch_rr which the name of requested
2374 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2375 handler MAY set this to reflect the schema of the returned record.
2377 New member 'display_term' in struct scan_entry. GFS now sets member entries
2378 and allocates scan entries to be filled by user scan handler. In previous
2379 version, entries member was allocated by the scan handler. That still works,
2380 but the GFS will ignore member display_term - assuming it was NOT set by
2381 the handler. The fact that the GFS now allocates the entries both allows
2382 for new members and makes a scan handler easier to write.
2384 Fix CQL lex buffer overflow.
2386 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2387 SRU default recordPacking is string.
2389 SRU protocol support for frontend server.
2391 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2393 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2395 Added scan for the ZOOM shell (zoomsh).
2399 * String Identifers for Schemas (Amendment 5).
2400 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2401 Old definition for schema
2402 Odr_oid *schema; /* OPT */
2407 Z_InternationalString *uri;
2408 #define Z_Schema_oid 1
2409 #define Z_Schema_uri 2
2412 * resultCount parameter to Sort Response (Amendment 1).
2413 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2415 Support for SRW 1.0 over HTTP. This is an optional feature and
2416 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2419 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2420 on the same port. SRW SearchRetrieveRequests are mapped
2421 to bend_init,bend_search,bend_fetch,bend_close.
2423 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2425 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2426 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2428 ZOOM connections are SRW based if schem http is used for hostname
2429 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2430 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2432 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2433 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2434 distance=n, order=true/false, relation=le, prox unit=word. If
2435 n is omitted, distance 1 is used.
2437 Fixed problem with C compiler include path in wrong order.
2439 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2440 on Solaris. Patch from Ko van der Sloot.
2442 New MARC decode API. All new functions operate on a yaz_marc_t
2443 handle. The most important new functions are: yaz_marc_create,
2444 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2445 decode and destroy respectively. Decoder can produce formats
2446 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2447 include/yaz/marcdisp.h.
2449 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2450 to UTF-8, UCS-32, wchar_t or Latin-1.
2452 * Prototypes for yaz_iconv_-functions moved to separate header
2453 include/yaz/yaz-iconv.h.
2455 Make a few private functions 'static' in unix.c. This prevents
2456 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2458 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2459 are set when Init Response is received.
2461 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2462 but returns diagnostic set as well.
2464 New function yaz_strerror which is a portable wrapper for
2465 strerror/strerror_r/GetLastMessage.
2467 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2468 is returned for MARC. If type is "oai", then OAI MARC is returned.
2470 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2473 --- 1.9.2 2002/11/26
2475 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2477 Fix bad race conditions on SIGTERM and terminate gracefully in
2480 Move retrieval (data1) module to Zebra since nobody seems to be
2483 Add GRS-1 render for ZOOM using same format as yaz-client.
2485 --- 1.9.1 2002/10/05
2487 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2489 Fix broken ESpec handling in data1 module.
2491 SGML reader parses comments and makes them part of the data1 tree.
2493 Added several type casts so that YAZ compiles as C++ code.
2495 ZOOM didn't handle PDU encoding failures properly.
2497 Added more Bib-1 diagnostics (approved extensions).
2499 GNU configure: better check for iconv.
2501 More portable use of accept, getpeername. Check for socklen_t. Use
2502 int/size_t if socklen_t is not defined.
2506 PQF parser rejects bad queries - including those with extra
2507 characters in them. PQF parser used to silently ignore that.
2508 Cleaner API for PQF added, which allows you to get detailed
2509 error information for bad queries (see yaz/pquery.h).
2511 Fixed bug in ZOOM_record_get for type "database".
2513 Implemented mini iconv library supporting conversions between
2514 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2516 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2518 --- 1.8.9 2002/08/20
2520 Fixed ZOOM C record cache so that preferredRecordSyntax and
2521 elementSetName is used to check for already fetched records.
2523 --- 1.8.8 2002/08/02
2525 Added three members in bend_initrequest structure to facilitate
2526 character set negotiation.
2528 Fixed a bug in frontend server that could cause indefinite
2529 loops under rare conditions.
2531 Revised character set utilities (charneg.h) so that encoding
2532 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2534 For PQF, directive @term <type> sets term type for Scan/Search.
2535 Here <type> is general, string, numeric, null. The term type
2536 is inherited - just like @attr.
2538 New call odr_set_charset that sets character set conversion for
2539 international-strings on a ODR stream. Prototype is:
2540 int odr_set_charset(ODR o, const char *to, const char *from);
2541 The InternationalString is still represented as C string in YAZ
2542 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2543 won't). On the protocol level, you can use any encoding.
2545 Support for UNIX sockets in ZOOM.
2547 Solaris recv sometimes returns errno == ENOENT. It is treated as
2548 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2550 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2551 both client and server. Code by Morten Bogeskov.
2553 --- 1.8.7 2002/05/22
2555 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2556 that they can be used directly from Visual Basic. You must recompile
2557 your windows APP if you're using ZOOM.
2559 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2560 Commands "lang" and "charset" sets language and character set respectively.
2561 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2562 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2564 Attributes from multiple CCL fields may be OR'ed rather than merged
2565 using directive "@field or". Fields are still merged by default -
2566 equivalent to "@field merge".
2568 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2571 Fixed bug in zget for parameter ExtendedServicesResponse.
2575 --- 1.8.6 2002/03/25
2577 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2579 Client displays USR.1:SearchResult-1 (hits per term).
2581 Additional Search Info for search in Generic Frontend Server.
2583 Fixed CCL parsing of "field=s".
2585 WIN32 installer - using the excellent NSIS software from nullsoft.
2587 Fixed CCL parsing of "field = - <number>".
2589 Added function yaz_marc_decode that decodes MARC for line mode
2590 display or XML (similar to that used by JZKit).
2592 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2593 Z39.50. But ISO/ILL was, however.
2595 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2596 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

2599 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2601 --- 1.8.5 2002/02/03
2603 New YAZ client features: Command completion and new commands:
2604 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2605 Code provided by Jacob Poulsen.
2607 New call oid_trav, that visits all registered OIDs via callback.
2609 Function ZOOM_record_get now returns const char pointer rather than
2610 void pointer. It saves a lot of type casts.
2612 For YAZ client, command "auth" now allows you to set authentication
2613 in IdPass style. It is enabled when three tokens are given - order
2614 is user, group and password.
2616 Fix memory leaks in MARC record handling for ZOOM.
2618 New option for YAZ client, -k <kilobytes> that sets
2619 maximum record size. Similar to -k option for generic frontend
2620 server and yaz-ztest.
2622 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2624 Prefix query parser reports "fail" when bad attribute set is given.
2626 Fix in MARC decoder. Proximity logging. Fix for attribute set
2627 in scan handler for server. Patches by Shigeru Ishida.
2629 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2632 Configure option --with-openssl=<dir> now works when a directory is
2633 specified. Patch provided by Morten Bogeskov.
2635 New option for YAZ client, -u <auth>, that sets authentication.
2637 ZOOM fix: error information was sometimes "missing", since error
2638 was cleared/reset too when it shouldn't.
2640 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2642 --- 1.8.4 2002/01/04
2644 Scan for ZOOM API. New object ZOOM_scanset. New functions
2645 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2646 ZOOM_scanset_destroy.
2648 New ZOOM function, ZOOM_connection_last_event, that returns type
2649 of last event (such as "receive data", "send data", "apdu received",
2652 New ZOOM option, schema, that specifies schema for retrieval.
2654 New CCL feature. Qualifiers can be aliases for one or more
2655 other qualifiers (if more than one is given, OR is used).
2657 ZOOM uses named result sets if target supports it.
2659 Two new YAZ client commands: . (dot, which sources a script of YAZ
2660 client commands), and ! (to execute shell command.). Implemented
2663 Working on Debian packages.
2665 --- 1.8.3 2001/11/19
2667 YAZ client enables named result sets only if target supports it.
2669 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2671 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2672 with key="host" to get same result.
2674 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2675 Function Z3950_resultset_record(s) returns references to records
2676 "owned" by resultset. To become owner use Z3950_record_clone.
2678 Function z_ext_record handles Extended Services. Thanks to
2681 --- 1.8.2 2001/11/12
2683 CCL Parser fix: ignore token comma when dealing with and-lists.
2685 Documentation updates for COMSTACK.
2687 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2688 Changed prototype Z3950_records. For some functions, int parameters
2689 were changed to size_t.
2691 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2694 New MARC decode/display function, marc_display_exl, which properly rejects
2695 non-ISO2709 records. YAZ client uses it.
2697 --- 1.8.1 2001/10/29
2699 Fix bug: local attribute set wasn't set correctly in PQF strings.
2703 * Old Z39.50 codecs no longer supported.
2705 Added ZOOM C binding. See http://zoom.z3950.org/
2707 Renamed states for COMSTACKs to avoid confusion with events.
2709 Implemented cs_look and proper cs_rcvconnect.
2711 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2713 Configure detects POSIX threads on OpenBSD.
2715 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2716 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2718 When error is returned from present handler, non-surrogate diagnostic
2719 is returned in present response (and fetch handler is no longer called).
2721 * Minor adjustments to pquery parser (PQF). Token characters may be
2722 escaped by using backslash (C-style).
2724 PQF parser allows string attribute values to be specified. For @attr,
2725 non-numeric characters after the equal-sign are treated as strings
2726 (e.g. @attr 9=title).
2728 CCL trunction character may be defined (@truncation in file)
2730 * function zget_ExtendedServicesRequest sets waitAction to
2731 waitIfPossible (was wait).
2733 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2736 CCL operator names may be set in field definition files (CCL_bibset).
2737 See ccl/bib1 for an example.
2739 Fixes in ASN.1 compiler for C++ compatibility.
2741 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2742 and "op_or" to avoid conflict with C++.
2744 Fixed problem with GNU readline detection on Redhat 7.0.
2746 Added step-size for Scan backend handler.
2748 Fixed bug that made the frontend server crash when no attribute
2749 set was specified for scan.
2751 Front-end server automatically switches to original working directory
2752 when installed as an NT service. Previously -w had to be specified to
2755 Added extended attributes for retrieval module (data1), so that data1
2756 records carry d1_readXML/SGML attributes. d1_read also supports
2757 null-data rules ( <tag/>)
2759 On UNIX when POSIX threads are available, a separate library libyazthread
2760 is created. Programmers should link with that library and the yaz library
2761 when using threads. The reason for the split was that some applications
2762 on Linux, such as Apache, doesn't work well when using shared objects that
2765 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2766 (or any frontend server) in SSL mode by specifying ssl: followed by
2767 address. Only tested on UNIX.
2769 Added feature for CCL module. Virtual structure s=al or s=ol generates
2770 and-list and or-list respectively instead of phrase search.
2774 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2775 log_mask_str. This was done to avoid name conflicts with other libraries
2776 (such as other PHP extensions).
2778 Added raw OID member for preferred record syntax (request_format_raw)
2779 and returned record syntax (output_format_raw) for backend fetch method.
2781 Config file yaz-config now accepts options so that it returns specific
2782 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2784 Shared library support for UNIX using GNU libtool.
2786 * Modified backend interface. Request/Response struct's replaced by
2787 one read/write C struct. For example bend_fetchrequest and
2788 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2789 Every handler - even search has to be registered in bend_init
2790 handler. This means that the YAZ library no longer refers to
2791 external functions and it makes it possible to make the whole
2792 thing a single DLL/SO.
2794 Added Segment handler for backend server.
2796 Added Zmbol/Zebra administrative functions to YAZ client.
2798 Threaded frontend server on UNIX (when POSIX Threads are available).
2799 Starting the server with option -T enables multi-threading.
2803 Added configure option --enable-comp/disable-comp to control use
2804 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2805 located in sub directory asn.
2807 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2808 in ${exec_prefix}/bin along with the other programs yaz-client and
2811 GNU automake used to maintain makefiles.
2813 Added several OID's.
2815 Changed retrieval module so that we can load records with no abstract
2816 syntax defined. Tagpaths in these records are fully composed of string
2819 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2823 On UNIX, the generated makefile now supports a proper 'make install'.
2824 The prefix can be set via GNU configure to set the install location
2825 (default is /usr/local).
2827 * YAZ programs client and ztest were renamed to yaz-client and
2828 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2829 locations, such as /usr/bin,/usr/local/bin,etc.
2831 * YAZ Header files were moved from include to include/yaz. YAZ Header
2832 files are referred to as include <yaz/log.h> rather than <log.h>.
2833 The YAZ include path (-I ..) is therefore the same as before. Programmers
2834 should update their #include statements or use -Ipath/include/yaz
2835 instead. The main motivation for doing this change is that YAZ header files
2836 can be installed in "standard" locations /usr/include,/usr/local/include
2837 without introducing conflicts, since ALL YAZ header files are stored
2838 in subdirectory yaz (under /usr/include for example).
2840 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2841 rather than project/workspace files. We switched because project files
2842 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2845 Changed name of logging function, logf, to yaz_log, to prevent name
2846 clash with some math-log functions. The YAZ header log.h defines logf
2847 to yaz_log (#define) so there should be no incompatibilities by this
2850 Added bend_start/bend_stop handlers for server. These handler are
2851 called on start/stop of server. For windows they are called whenever
2852 a service is started/stopped.
2854 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2855 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2856 in util/yc.tcl. The auto-generated C code structures are, in a few
2857 cases, incompatible with the old decoders. There are differences in the
2858 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2859 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2860 The preprocessor variable ASN_COMPILED is defined when the compiled
2861 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2862 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2863 wish to use the old encoders/decoders you can specify --disable-yc
2866 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2867 version so that it supports both new - and old version of DB Update
2869 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2870 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2871 change. The name parameter can be set to 0 in which no name is specified
2872 for the construction. The macros odr_implicit and odr_explicit sets name
2873 parameter to zero for the construction involved. New macros
2874 odr_implicit_tag and odr_explicit_tag are similar to the others,
2875 except that a name parameter is added. For programmers' that don't use
2876 ODR they probably only need to change the call to z_APDU and z_External.
2878 Added access control facility by interfacing the TCP wrapper library.
2879 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2880 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2881 name of the daemon and enables the access control as specified in
2882 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2884 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2885 den Dool <H.M.vdnDool@kub.nl>.
2887 Added reference ID parameter to most functions in server API - refer
2888 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2890 Changed name of ccl library to libccl.a (was ccl.a).
2892 Fixed bug in decoder for Explain (Category TargetInfo).
2894 Added support for GNU readline in client. Thanks to Jacob Poulsen
2895 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2897 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2898 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2899 IMPLEMENTATION! This change was made to the development version before
2900 the ZIG decided to retract the amendment. If any users MUST be
2901 compatible with the original Update definition, PLEASE CONTACT US, and
2902 we will include a separate definition corresponding to the old Update
2903 ES. Note that because of the change to the ASN.1 of the
2904 TaskPackageRecordStructure we cannot define a single structure that
2905 will support both versions.
2907 * Added const modifier to buffer parameter for some ODR/BER encoding
2908 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2909 completeWAIS, odr_dumpBER.
2911 Fixed bug in client.c which caused a crash when a scanResponse didn't
2912 contain positionOfTerm.
2914 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2915 * will cause an error in a client if a non-YAZ target sends both a
2916 * list of Scan entries and non-surrogate diagnostics.
2918 Retrieval module enhancements. Tag sets may be typed in the reference
2919 to it. From the .abs-file the "tagset" directive takes a third optional
2920 integer type for the tag set referenced. From a .tag-file the "include"
2921 directive takes a third optional type as well. The old "type" directive
2922 in the tag set itself is still recognized but acts as the default type
2925 Backend interface change. Individual Scan terms returned from bend_scan
2926 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2927 in include/backend.h.
2929 Retrieval module enhancements. Multiple tag sets and attribute sets may
2930 be specified in abstract syntax specs. Revised the error/warning for
2931 logging messages reported by the retrieval module when reading the
2934 Object Identifier system (oid_..) changed. The API is backwards
2935 compatible but the oid-routines now allocates new OID's when needed.
2936 Raw OID's may be specified in oid_getvalbyname.
2938 YAZ now uses GNU configure to generate Makefile(s).
2940 * Minor changes in some of the member names of DeleteResultSetRequest and
2941 DeleteResultSetResponse. See include/proto.h.
2943 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2944 and added member 'languages' in TargetInfo (which was missing).
2946 Changed the way attribute sets are handled in the retrieval
2947 module. These are now cached, just like the abstract syntaxes
2950 Changed YAZ so that it links with compiled ASN.1.
2952 Added Explain-schema definitions and mapping routines. The following
2953 Explain categories have been implemented: AttributeDetails,
2954 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2956 Fixed minor bug in Windows version of Server Library.
2958 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2960 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2962 Added EXTERNAL: UNIverse Resource Report (non-standard).
2964 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2965 ENUMERATED and SET OF.
2967 * Added 'const' to some of the char pointer arguments for the
2968 functions, data1_read_node, data1_getelementbytagname,
2969 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2972 Fixed bug in data1_insert_taggeddata - the last_child member of
2973 parent wasn't initialised.
2975 * Changed data1_read_record and data1_read_node so that the supplied
2976 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2977 doesn't refer to any parts of the "SGML"-buffer.
2979 Fixed bug in server library (Windows version of statserv_remove).
2981 * Changed code so that it compiles as C++. The type definition
2982 of Odr_fun which is a member of Odr_arm was changed. The result is,
2983 that an explicit typecast is needed for the fun pointer when
2984 using Odr_arm - as in:
2985 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2987 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2989 Implemented the new structured date and time definition as approved
2990 by the ZIG. Added schemaId element to the specificTag in Espec-1
2991 (also approved at the last ZIG). Thanks to RVDM.
2993 Added some Object identifiers (RVDM).
2995 Changed the Update Extended Service (RVDM).
2997 Added command "refid" to client which specifies referenceId for
2998 the following requests.
3000 Implemented extended service handling for server. See ztest.c
3001 for an example as well as backend.h. New handlers are registerd
3002 in the Init handler.
3004 * Changed interface for sort in server.
3006 Added new members to statserv_options_block. It allows a server
3007 to read options from another source than just the command line. Thanks
3008 to Charles Woodfield.
3010 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3011 renamed to zboolean. Some C++ compilers complained about the name.
3013 Minor changes to gils.abs. Added index 's' (sort) on title
3014 and date/time-last-modified.
3016 --- 1.4pl2 1998/1/30
3018 Fixed bug in server library regarding inetd mode (-i). This bug
3019 was introduced by release 1.4.
3021 --- 1.4pl1 1998/1/29
3023 Added sort facility in client and backend server interface.
3025 Fixed problem with dependencies in Makefile(s).
3027 Fixed bugs for encoders/decoders of extended services and
3030 Implemented sub-tree feature for schemas. Sub-trees are
3031 referenced in *.abs-files. See explain.abs for an example
3032 of the use of this feature.
3034 Modified bib1.att; local attributes for ANY didn't include
3035 ANY itself (only affects use of the retrieval module).
3037 Fixed bug in plain SGML reader in function data1_read_node:
3038 tags with prefix "var" was incorrectly interpreted as variants.
3040 Added feature "sub-schemas" to enable references to - and definitions
3041 of - group of elements.
3043 * Removed member parent from type data1_element (in data1.h).
3045 Implemented function odr_nullval() that returns the value of
3048 * Removed member num_children from data1_node (in data1.h).
3050 Made NT service interface part of the server library. The
3051 function statserv_main uses the NT service when required and
3052 calls the statserv_start / statserv_close routines.
3054 Routine zget_SearchRequest and zget_PresentRequest fills
3055 resultSetName/Id member with "default" instead of "Default".
3057 Fixed memory leak in server. Request queue member wasn't freed.
3059 Fixed nmem_exit so that memory is freed.
3063 Revised the CCL parser utility to be thread safe.
3065 Added function, oid_ent_to_oid, to replace the function
3066 oid_getoidbyent, which is not thread safe.
3068 * Added nmem_init and nmem_exit to initialize and release
3069 NMEM resources. Function nmem_init should be called once in the
3070 initial thread before NMEM/ODR is used. statserv.c and client.c
3071 have been changed accordingly. The change was necessary to make
3072 NMEM thread safe. The NMEM memory pool is shared amongst threads
3073 in a process. Unix-based applications will still work fine without
3076 Added NT Services interface for the the Z39.50 (statserv) Server.
3077 Refer to the ztest.c source on the usage.
3079 Windows 95/NT port using MSVC5.0. Project files are included in the
3082 * Defined new 'global' handle for the retrieval (data1) system. The
3083 new handled, data1_handle, describes the state of the data1 system.
3084 This handle is passed as first argument to virtually all
3085 data1 related routines. The functions data1_create and data1_destroy
3086 creates and destroys a data1 handle respectively.
3088 Added ODR encode stream member to all backend request structures
3089 init, search, scan etc. This stream should be used to allocate all
3090 memory used for the response when thread safe operation is needed.
3092 Changed the comstack utility, cs_addstr, to be thread safe. The
3093 returned hostname string returned by the function is now part the
3096 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3097 function. The cs_straddr takes a COMSTACK handle as argument, so this
3098 function must be used after cs_create and before bind/connect.
3099 This function is thread safe.
3101 Moved test server to 'ztest' directory - generic server code still
3102 in 'server' directory.
3104 Made prefix query (pquery.c) utility thread safe.
3106 Added new function modifier YAZ_EXPORT to 'export' public DLL
3107 functions when using windows (see include/yconfig.h).
3109 Added definitions to the OID database (util/oid.c) (RVDM).
3111 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3113 Added call to ccl_rpn_delete in client program.
3115 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3116 release of RPN structure.
3118 Added support for C++, headers uses extern "C" for public definitions.
3119 With input from RVDM.
3121 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3122 Thanks to Ronald van der Meer (RVDM).
3124 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3126 Added support for private extensions to the OID database
3127 (oid_setprivateoids()). Thanks to RVDM.
3129 Added optional, physical ANY (key replication)
3131 Fixed null-reference problem in GRS-1 output filter.
3133 Proximity operator added to Prefix Query Format (PQF).
3135 In test client command "base" accepts multiple databases.
3137 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3141 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3143 Smallish bug-fixes in the new encoders/decoders (explain).
3145 Bug fixed in DeleteRequest.
3147 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3149 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3151 Added SOIF syntax (using private OID for now) to retrieval module and client.
3153 Added Update extended service.
3155 Added SearchResult-1 additional info structure.
3157 Added optional CCL (ISO8777) interpreter as separate module. Available
3160 --- 1.2 1996/6/10 (1st anniversary release)
3162 Added Summary record syntax. Lightly tested.
3164 Added OPAC record syntax. Untested.
3166 Added ResourceReport service encoders/decoders. Untested.
3168 Fixed bug in z_Unit - wrong tagging on unitSystem.
3170 Fixed bug in the DiagRecs decoder.
3172 Added options for max PDU size and session timeout to frontend-server.
3174 Added documentation of query-language parsers and other supporting utilities.
3176 [frontend-server] Added Attribute set to the bend_scanrequest API.
3178 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3179 surrogate diagnostics were generated.
3181 [retrieval] Allow multiple local values for attribute.
3183 [retrieval] Allow multiple attributes per element in .abs files. index type.
3185 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3187 --- 1.1pl2 1996/4/10
3189 Minor changes, mostly specific to Zebra's requirements (retrieval)
3193 Repaired bug in frontend server when running multiple listening
3194 endpoints in dynamic mode.
3196 z_External() now won't break if a known, ASN.1 value comes encapsulated
3197 in an octet-string. The value will pass through unmodified in an Odr_oct.
3199 Added a bit of code to the demo client to decode & display
3200 ASN.1-structured records represented in the octet-aligned branch of
3201 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3203 Added z_ext_getentbyref() to the ASN module. Doc updated.
3205 * Completed the SCAN definition in the ASN module. This may break SCAN
3206 code based on older YAZ-versions at compile-time. The fix is easy -
3209 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3210 under the SCAN definition. Remember to initialize this, server-people.
3212 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3213 that this does not extend to ODR and ASN.
3215 Comstack allows insertion of established socket (primarily for
3216 inetd-operation of servers). Doc updated.
3218 Front-end server can now start from the inetd in TCP mode. Doc
3221 --- 1.0pl4 1996/1/24
3225 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3226 the rank and record number.
3228 Adjustments to the frontend server.
3230 Fixed diagnostic BER dumper. It ignored the file argument.
3234 Various changes to retrieval module.
3236 Changed the union discriminators of the protocol files from enums to
3237 ints paired with #defines.
3239 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3242 *Changed operator in the RPN structure to 'roperator', again to avoid a
3245 Fixed problems in Explain decoders/encoders.
3247 --- 1.0pl2 1995/12/6
3249 Memory bug in log module fixed.
3251 --- 1.0pl1 1995/12/5
3253 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3255 Bug in Explain DatabaseInfo module fixed.
3257 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3261 The shift to v1.0 signals that we now consider the *core* functionality
3262 of YAZ reasonably stable (the core being more or less equivalent to
3263 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3264 tested (Explain not at all - though that will happen soonish).
3266 Minor changes to code to support Windows port.
3268 Various minor changes after we're getting to use GRS-1 & co. more.
3270 Added Espec-1 format.
3272 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3273 of the protocol and it cannot be selected when encoding (maps into 'string'
3274 when decoding). Needed to talk to some servers.
3276 Demo client can request simple element set names.
3278 Added Diagnostic Format encoders/decoders.
3280 Added simple Close handling to frontend server (no hooks for resource
3281 reporting yet), and demonstration client.
3283 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3285 --- 1.0b3 1995/08/24
3287 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3288 handled incorrectly when records were requested in the searchResponse. This
3289 will only affect you if you use the frontend-server.
3291 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3292 Test-client will ask for and print GRS1. Ztest will return dummy records
3295 Added Explain encoders/decoders to the service-level API. Untested.
3297 Added Extended Services: Item Order encoders and decoders to the Service-
3298 level API. Untested. We could use a recent copy of the pertinent bits
3299 of the ILL protocol to add those bits.
3301 Added diagnostic format 1 encoders/decoders to the service-level API.
3304 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3305 odr_cons.c, which causes a more correct output.
3307 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3308 was always set to 0 when no records were requested in the searchRequest.
3310 * Added better external-handling. This shouldn't harm old code that
3311 *encodes* externals. It can break code that looks for a
3312 'single-ASN1-type' representation, since those types that are known
3313 are now decoded immediately. Look at the SUTRS sample code in
3314 seshigh.c and client.c. Documentation updated.
3316 Handling of structured records in bend_fetchresponse. Length -1 marks
3317 structured record, type is deduced from format field.
3319 --- 1.0b2 1995/06/27
3320 Fairly quick maintenance release to add SUTRS support.
3322 Fixed handling of SUTRS records in the demonstration client.
3324 * Added format field to the bend_fetchrequest and bend_fetchresponce
3325 structures of the backend API (frontend server). When the record is
3326 returned, the value of the format field is mapped to an OID. The
3327 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3328 of the record. The special value VAL_NONE in the bend_request means
3329 that no specific format was requested by the client. Documentation
3330 updated accordingly. Test server (ztest) will return a fixed dummy
3331 SUTRS record if your client requests SUTRS.
3333 Documentation updated accordingly.
3335 You can now set external libraries and RANLIB support in the top-level
3339 First public release.
