3 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
6 MARC: Extra/missing indicator handled for MARCXML.
7 The indicator length is given in header and is the same for the
8 whole record. If attributes ind1, ind2 are missing, then content
9 character defaults to blank. Extra indicator attributes (beyond)
10 indicator length are treated as an error.
12 Reformat: delete trailing whitespace
16 MARC: fix non-ASCII characters for leader. This is to ensure we can
17 generate XML in UTF-8.
19 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
20 in one node with structure word.
24 yaz-json-parse: JSON output may be pretty printed by using option
27 Increase default value of max message for Z39.50 Init for GFS, ZOOM
28 and yaz-client. Old value was 1 MB. New value is 64 MB.
32 yaz-client: don't display bogus records from SRU servers. Some SRU servers
33 return more records than given by *maximumRecords*. Skipping those in
36 record_render: simplify buffer return handling and fix at least one bad
37 memory reference, that broke the test_embed_record sometimes.
39 Allow http://user:pass@host notation for yaz_url_exec.
41 zoomsh: allow shell command to be executed. Via the system(3) call.
43 yaz_poll: Allow num_fds == 0
45 yaz-client: fix bad encoding of "itemorder item". The itemorder
46 item <no> - command forgot to use length of encoded Item Request
47 package. Error present since YAZ 3.
49 yaz-ztest: fix bad usage of session handle. Bug was introduced when
50 result sets were saved (271a9c83).
52 SRU recordPacking: guess record packing in response rather than looking
53 at the recordPacking element which, OF COURSE, changed semantics in SRU
56 Decode SRU 2.0 responses. The official namespace for responses, according
57 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
58 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
59 nature.com's server, however, usee namespace
60 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
61 we are now using a glob-expr to match up the namespace. ZOOM C and
62 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
63 I can not find a single real example showing the "real" namespace in
64 the documentation from OASIS. The namespace for requests is different
65 from responses, but this is not added to YAZ yet, when we don't encode
70 zoom/record_render: add support for Base64 decoding fo MARC records
71 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
72 which will decode base64 + ISO2709 marc-8 encoded material from text node
77 Add missing definitions ZOOM_resultset_get_facet_field_by_index
78 and ZOOM_resultset_facets_names.
80 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
83 Change APDU dump printing to avoid long leading blanks. For levels 16
84 or larger the level is shown and the indentation is truncated but
85 recursed with modula 8. This makes it still reasonable easy to read
86 - even for nested BER dumps.
88 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
89 return 0 (incomplete package) in case where the BER package was
90 considered too nested (return value of -2).
92 dumpber: lines of level 15 are not indented further. Two spaces per
93 indentation; indentation 15 or more is indented to a fixed indentation
94 and augmented with a level=<no> indication.
96 zoomsh: increase max size of command+args
98 GFS: No limit in RPN buf size in CQL to RPN conversion.
100 --- 4.2.33 2012/05/09
102 New function for daemon utility, yaz_daemon_stop .
104 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
106 --- 4.2.32 2012/04/25
108 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
109 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
111 --- 4.2.31 2012/04/23
113 YAZ daemon utility relays SIGUSR1 to child process.
115 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
116 would result in en empty database list - which in turn would result in
117 encoding failure for search.
119 Fix reading beyond string in yaz_sort_spec.
121 --- 4.2.30 2012/04/11
123 Add two new SRU diagnostics:
124 236: Access to specified database denied
125 1015: Init/AC: Maximum number of simultaneous sessions for Userid
127 Document the very useful ZOOM-C option "apdulog".
129 CQL to RPN: term may be passed through verbatim. This is enabled with
130 truncation.cql . The assumption being that the term is already CQL.
132 --- 4.2.29 2012/03/20
134 record_conv: leader spec may be given for marc element.
135 The leader spec is given as attribute leaderspec for element marc.
136 For example to convert a MARC21 record from MARC-8 to UTF-8:
137 <marc inputformat="marc" outputformat="marc"
138 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
140 record_conv: allow user-XSLT params. For example:
141 <xslt stylesheet="MARC21slim2DC.xsl">
142 <param name="myparameter" value="myvalue"/>
143 <param name="otherparameter" value="othervalue"/>
146 record_conv: fix error handling for missing marc charsets.
148 CQL: fix extra terms in wrong order.
150 --- 4.2.28 2012/03/06
152 record_conv: modify new API for conversion types. The conversion types
153 may be passed in new functions yaz_record_conv_configure_t and
154 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
156 Avoid mixed statement/variable declare; fixes compilation with Visual
159 --- 4.2.27 2012/02/28
161 Add non-standard SRU diagnostic: 235: "Database does not exist".
162 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
163 Update SRU to Bib-1 diagnostic maps accordingly.
165 CCL: add two new diagnostics for unsupported masking. The new
166 diagnostics are: "Embedded truncation not supported" and
167 "Single charcacter mask not supported".
169 --- 4.2.26 2012/02/23
171 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
173 --- 4.2.25 2012/01/11
175 Build YAZ for Ubuntu Oneiric.
177 CCL: allow parantheses for proximity operands. For example CCL query
178 (a) % (b) is now allowed.
180 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
181 marked dead, rather then being destroyed. If not, the session memory is
182 being free'd before the search/scan handler is finished. Also destroy
183 'request' memory in request_release rather than in various places,
184 which resulted in leaks from time to time.
186 --- 4.2.24 2011/12/21
188 cql_sortby_to_sortkeys: honor sort prefix.
190 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
191 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
192 The rpn2cql family of functions now always returns quoted CQL terms.
194 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
196 --- 4.2.23 2011/12/15
198 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
199 sequence is treated as one. For example, &&a=b&&&c& is identical to
202 --- 4.2.22 2011/12/05
204 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
205 APDUs for a connection to a WRBUF.
207 --- 4.2.21 2011/11/23
209 Fix cql_sortby_to_sortkeys. Completely broken before.
211 Make CCL's @truncation work again.
213 --- 4.2.20 2011/11/09
215 New ZOOM connection setting: tproxy. It's like proxy, but does not
216 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
217 to set resolved address + port for a connection outside ZOOM itself.
219 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
221 --- 4.2.19 2011/11/07
223 Fix uninitialized variable in Solr spell support (could cause SEGV
224 for SRU response decoding).
226 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
227 back-end's addinfo through into the ZOOM response addinfo.
229 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
230 they are separated by a colon and a space rather than simply
233 --- 4.2.18 2011/10/28
235 Add support for Solr spell-checking/suggestions through ZOOM.
236 If a Solr target has been configured correctly for spelling-checking
237 and suggestions, these will now be returned on the ResultSet option
238 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
240 --- 4.2.17 2011/09/28
242 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
243 with a flag whether to substitute escape sequences or not.
245 --- 4.2.16 2011/09/22
247 Fix nmem_strsplit_escape to substitute escape char properly.
249 New option for zoomsh -e , which makes it abort on first error and
250 return process exit code to indicate success/failure.
252 YAZ options utility supports special option -- which makes all it treat
253 all following arguments as non-options.
255 --- 4.2.15 2011/09/16
257 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
258 searched if absolute filename is given.
260 Fix conv_xslt() error-reporting when stylesheet is not found.
261 (The value of fullpath is meaningless in this situation.)
263 --- 4.2.14 2011/09/07
265 Fix problem in CQL sort node creation: un-initialized memory.
267 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
268 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
269 CQL sortby depending on whether Type-1 or CQL is actually sent to the
272 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
273 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
275 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
276 will make it possible to use both single-character mask (#) and wildcard (?)
277 in CCL . Throw diagnostic for left truncation because that is not supported
280 --- 4.2.13 2011/09/01
282 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
283 cases using escapes (\-sequences) and masking.
285 PQF parse fix: A trailing backslash followed by end-of-string (\0)
286 would result in a read one byte beyond string.
288 rpn2ccl may use Z39.50 masking for terms (t=z).
290 ICU check fix. Don't include library -lCrun on Solaris, unless present.
292 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
293 not --cppflags (which seeems like an error in icu-config).
295 --- 4.2.12 2011/08/27 RPM package only
297 cql2ccl: fix conversion of terms: operator characters were not
300 --- 4.2.11 2011/08/25 RPM package only
302 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
303 CCL parser will map both # and ? to their regular expression
304 quivalents (. and .*).
306 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
307 of reserved CQL characters.
309 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
310 is, so that they are passed through.
312 --- 4.2.10 2011/08/24
314 ZOOM SRU mode: more aggressive re-connect.
316 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
317 made available as a utility function, declared in <yaz/logrpn.h>
319 rpn2cql_structure() supports proximity nodes (except that the Type-1
320 proximity node's "exclusion" binary is ignored, as there is no way to
321 express that in CQL). Fixes bug #4564.
325 Fix SEGV that could occur if set command of zoomsh was given without
326 value (2nd argument).
328 Fix SEGV that could occur if unsupported transport was given for
329 COMSTACK - say https (when SSL was unavailable).
331 Build yaz-url on Windows too.
335 New utility to get web content. Header is url.h. A command line tool
336 yaz-url is part of the distribution and packages.
338 Fixes for SSL COMSTACK (when gnutls is in use).
340 New functions yaz_base64{encode,decode}. Header is base64.h.
344 ZOOM C includes HTTP response buffer as additional info if it fails
345 to decode the SRU response.
347 Make wrbuf_json_puts available.
351 zoom: throw diagnostic for invalid value for option "sru". Before a
352 bad SRU request was sent.
354 Adding new utility wrbuf_vp_puts.
356 Add cclxmlconfig.obj to win/makefile. It was missing completely.
360 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
361 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
362 redirect was used at the same time.
364 MARC line mode decoding: be less picky about length given - first
365 5 digits of header that is.
367 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
369 Changes to decoding of SRU records: a record with recordPacking=xml is
370 modified with a new root element <yaz_record> if the recordData contains
371 multiple children elements. This is to make the record XML parseable
374 RPN to SOLR conversion: encode special characters.
376 Generic Frontend Server: fix uinitialized member, stepSize.
380 Fix a bug in SRU decoding of records.. The database records stored
381 had un-initialized memory, but it would only be seen with yaz_record_render
382 and type_spec="ext" .
384 Fix a bug in ccl_qual_dup introduced in 4.2.3.
388 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
392 Add new utilities to convert from CQL to CCL . These utilities have
393 prefix cql_to_ccl defined in cql.h.
395 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
396 lead to memory heap corruptions when ICU utilities were in use.
400 Make compilation work without Libxml2.
402 yaz-client: remove redundant blanks in display of searchResult-1 term
407 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
408 resulting CQL node (tree) in a new node CQL_NODE_SORT.
410 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
411 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
412 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
413 Note that the CQL sortby spec is only converted when the GFS is already
414 converting from CQL to RPN (cql2rpn element).
416 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
417 specify whether to collapse delimitors or not. The existing nmem_strsplit
418 do collapse (collapse parameter = 1).
420 Windows installer: For NSIS, set InstallDir depending on x86/x64.
422 Rename internal func yaz_use_attribute_create. While non-static, this
423 function is not declared in a public header.
427 Add -lCrun when linking with ICU on Solaris.
429 More quicks character set conversions for OPAC records.
433 fix problem with record_render: records were converted (character set
434 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
438 SRU: add methods for handling DADS SRU-proxy facets.
440 Separate OPAC record character set for ZOOM_record. yaz_record_render
441 allows a character set given as charset=from/opacfrom,to where 'from' is
442 the character set of a bibliographic record, 'opacfrom' is character set
443 of OPAC record and 'to' is the target character set.
447 yaz-client: show may XML format records. Command show followed by 'format'
448 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
451 src/stemmer.c: Avoid using unnamed union. It is not supported by some
454 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
457 Update yaz.spec to operate on both SLES11 / Centos 5.5.
459 RPM: Release includes 'indexdata' name. Use indexdata in release name so
460 this package can be distinguished from other vendors.
462 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
463 as determined by configure
465 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
467 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
468 returns no error and no record, the present request is considered
469 partial (only a subset of the records could be returned by backend), and
470 so it is appropriate to set Present Status to partial-4.
474 Move yaz-config man pages to section 1.
476 More documentation about SOLR.
478 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
479 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
480 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
481 peers on some Linux systems. However, in general that does not work
482 so YAZ can not rely on that to work. Debian changed behavior in this
483 respect from Debian lenny to Debian squeeze (still testing as of Oct
485 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
487 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
491 Fix yaz-config output: echo_source not set correctly by configure.
495 SOLR WebService support for yaz-client and ZOOM.
497 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
499 --- 4.0.12 2010/08/17
501 Z39.50 facet support. Facet specifications are passed for search in
502 other-information with ASN.1 as defined in facet.asn and OID
503 .10.1000.81.5 . Facets are expressed as an Attribute list as known
504 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
505 3 is limit (number of entries to get in response). yaz-ztest returns
506 dummy facets if a client asks for them.
508 --- 4.0.11 2010/07/09
510 CCL fixes: bug 2895 and bug 3539.
512 GR1-display: add comma in display - was removed by mistake in
515 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
517 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
519 --- 4.0.10 2010/06/18
521 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
522 result set from a connection. The result set will be on its own
523 thereafter; no operations on it will perform retrievals from a target.
524 Only cached copies are returned.
526 ZOOM C:fix case for HTTP servers responding with Connection:close.
527 Ensure that if there is a current task it is resumed (like fetching
528 more records in a result set) . Bug #3484.
530 PQF parser: use odr_atoi for Odr_int (not atoi)
532 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
533 values that contain any non-digits are treated as string attributes
534 (previously decoding only checked for leading character ([0-9]). PQF
535 encoding: attribute string values are not surrounded by double-quotes.
539 New utility for managing threads - thread_create.h.
541 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
542 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
543 but YAZ' implementation do.
545 Fixes for yaz_cond-functions on Windows 7.
547 DLL export more symbols.
549 zoomsh: show record do NOT render opac.
551 Remove *.la files from Debian and RPM packages.
555 Debian package libyaz-dev depends on libgnutls-dev again (was
556 removed in YAZ 4.0.6, but due to Libtool it is still needed
557 even though yaz-config do not list libgnutls libs).
559 ZOOM: Use only one WRBUF for returning string results for
560 ZOOM_resultset. Reduces memory usage for ZOOM in general.
562 ZOOM: ZOOM_connection do not use a shared pointer to
563 ZOOM_resultset after ZOOM_resultset is destructed by
564 user. Reverts to YAZ 4.0.4 behavior.
568 record-conv: fix problem with at least one XSL conversion -
569 due to probably incorrect usage of XML XSL documents.
573 Fix yaz-config for static mode and the use of SSL (gnutls).
577 Forward decl timeval struct in mutex.h and gettimeofday.h.
579 yaz-config: fix 'static' mode linking.
583 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
584 are wrappers for pthreads or Windows. For Windows these are put in
585 a separate DLL: yaz_cond4.
587 libyaz.la (whole source) is compiled with thread. If thread support
588 is enabled enabled, all source of YAZ is compiled with treading support.
589 This allows core utilities such as yaz_log to use thread facilities.
590 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
591 thread utilities. This commit moves mutex utilities (mutex.c) from
592 libyaz_server.la to libyaz.la.
594 yaz-json-parse displays leading text until error.
598 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
599 patch from Giannis Kosmas.
601 SRU: no longer URL encode SRU database. The URL for an SRU server is
602 a URL and such is alreeady encoded - at least when given with leading
603 http:// or https://. This reverts behavior to YAZ 3.0.50.
605 Support for new MARC XML notation TurboMARC which like MARCXML is a
606 complete representation of MARC/ISO2709.. This one, however, is more
607 compact and allows for faster processing with XSLT. TurboMARC can be
608 used in the marcdisp.h API, from the yaz-marcdump utility and from
611 yaz-ztest can be configured - via the database - to perform certain
612 delays when it performs operations search, present and single record
613 fetch. This allows testers to make yaz-ztest act as a real or even slow
614 Z39.50 server. Refer to the yaz-ztest man pages for details.
618 wrbuf_destroy allows NULL WRBUF passed to it.
620 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
622 Add ZOOM_connection_close.
624 No fixed size buffers for ZOOM shell - bug #3257.
626 tstodr: make it work on s390 platform.
628 New icu iterator-functions. The new icu_iter-functions makes it possible
629 to use ICU chains from many threads.
631 yaz-client: better syntax check for show command.
635 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
638 New simple local-file XML include facility which allows file glob-patterns.
639 Refer to yaz/xml_include.h.
641 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
644 ZOOM_record_get supports new parameter "format" which makes it format XML
647 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
648 JSONText in ECMA-262) is JSONValue, not JSONObject.
652 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
653 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
655 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
656 POSIX/Unix builds .so with major version 4.
658 Remove old LOG_-defines from log.h. They have been obsolete and
659 undefined by default for the last 5 years.
661 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
663 GFS: Remove socket (int *fd) from search_rr handler. The socket
664 descriptor ptr is a facility that allowed a search handler to supply
665 a socket which would serve as a callback - when search was complete.
666 This facility has now been in use for years.
668 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
669 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
670 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
671 returns 'const char *' rather than 'char *. The returned string is
672 read-only and should not be modified by applications. COMSTACK cs_close is
673 now a void function - it no longer returns int. No applications check for
674 the value and the implementations has always returned 0.
676 ZOOM: use size_t for scan hit counts and str size. Functions
677 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
678 occ (hit count) and len (string length) are now of type size_t pointer
679 rather than int pointer. This is to be able to represent large hit counts
680 and to also just to use the proper type for string length (strlen result).
682 New JSON parser. Refer to include/yaz/json.h .
684 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
685 Used to be int in some cases. Many wrbuf_-functions used to return an int
686 indicating some length.. These return values were never used. And so they
689 ODR: odr_malloc, odr_total now takes size_t for size.
691 clone_z_type: fix leak; occurred for encoding failures.
693 --- 3.0.52 2009/12/03
695 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
696 bug was introduced in 3.0.51.
698 --- 3.0.51 2009/12/02
700 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
702 tcpip comstack: fix leak for getaddrinfo.
704 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
705 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
706 Decoding of SRU "path" database is performed by private function
707 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
708 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
710 yaz-client: honor base command for SRU. Change when database setting
711 is applied for SRU and ensure it is kept when a connection is reset.
712 Change also the way errors are displayed or SRU (decoding of packages).
714 --- 3.0.50 2009/11/02
716 Add support for extra request / response data for SRU codecs and GFS.
717 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
718 for extra data response buffer and length. For the GFS, both request
719 and response data (XML) is carried in extra_args and extra_response_data
720 for the search handler. Patch by Ko van der Sloot.
722 ZOOM: For queries that cannot be converted to the specified rpnCharset,
723 ZOOM now returns a diagnostic on the client-side ('invalid query' /
724 10010). This fixes bug #2113.
726 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
727 cmdfile included a 'quit' command that would result in a memory violation.
729 --- 3.0.49 2009/10/01
731 Make a number of functions defined in xmlquery.c static. These have
732 never been declared in a public header file (yaz/xmlquery.h) and was
733 made public by mistake.
735 Improve speed of character conversions (iconv utilities). This makes
736 conversions from MARC-8 faster.
738 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
739 unless type desired is "raw". This will prevent type "xml" from
740 returning ISO2709 .. Which obviously can not be XML parsed.
742 Fix memory leak in ZOOM that would occur if option apdulog was used
743 on a re-used connection.
745 Frontend server logs HTTP requests.
747 Frontend server now sends Z39.50 close when it times out (sesssion has
748 been idle for too long). Versions 2.0.30 and earlier also sent close.
749 But due to a mistake this was disabled in all versions after that, i.e.
750 the server would just close the socket immediately.
752 yaz-client emits a better message when receiving an unrecognised
753 userInformationField.
755 Skip zero-length subfields when decoding ISO2709. This rare case happens
756 if a record has two FS characters in a sequence. Without this patch
757 there would be a reference beyond char array in using_code_len fragments
760 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
762 --- 3.0.48 2009/08/28
764 The show command offered by the zoomsh command now takes a 3d optional
765 parameter type which is what is passed to ZOOM_record. If the type
766 argument is omitted, "render" is used.
768 RPN to CQL conv may use USE string attributes (bug #2978).
770 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
772 --- 3.0.47 2009/07/08
774 Function yaz_xml2query allows a diagnostic element in the PQF XML
775 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
776 code and additional info respectively.
778 The BER BOOLEAN is now the integral type Odr_bool which still happens
779 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
780 typedef'd to Odr_int. This is still an integral 'int', but it may be
781 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
782 ASN-1 compiler as well as programs has been updated to use the new types.
784 --- 3.0.46 2009/06/08
786 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
787 only the bibliographic record was rendered. For type=opac, an OPAC
788 record is only returned if it is present.
790 iconv: small fix for encoding of advancegreek.
792 yaz-client: avoid double display of SRU/SRW records (bug #2798).
794 yaz-client: option auto_reconnect=on really reconnects.
796 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
798 server: avoid null ptr ref for for yaz_poll errors.
800 build: fix RPM build for RHEL 5.3.
802 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
804 --- 3.0.45 2009/03/31
806 Fixed bug #2709: TCP connect returns Invalid argument.
808 Fixed compilation for mingw.
810 Honor charset for raw records (ZOOM_record_get).
812 Fixed use of errno for threaded mode that was seen on Solaris 10.
814 Fixed argument passing with blanks in value for Windows Service.
816 Disable YAZ' own log rotate by default (no 1 GB limit).
817 The variable l_max_size which specifies the log file limit is set to 0
818 (DISABLED): This is due to the fact that YAZ is most often deployed using
819 logrotate. Also YAZ can not perform log rotate because of unsufficient
820 permissions (setuid).
822 --- 3.0.44 2009/02/17
824 List supported encodings in man page for yaz-iconv.
826 Fixed missing SSL libs for --libs output
828 Re-established OID record syntax application-xml. Nobody should use it
829 but we don't want to change soname because of this symbol being absent.
831 --- 3.0.42 2009/02/02
833 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
835 Added member named_result_sets for init handler struct for the GFS. This
836 allows a server to disable named result sets.
838 Removed OID record syntax application-xml.
840 Added support for rule-based transliterator for ICU wrapper of YAZ.
842 Fixed bug #1902: yaz-icu XML output.
844 Make YAZ checks Emacs friendly.
846 BITSTRING value shows value. Bug #2346.
848 ISO2709 decoding: skip control characters from indicator data.
850 Omit sort key by default in yaz-icu's output.
852 Allow combined single char options (again) for YAZ' options function.
854 Utility yaz-marcdump got option to display YAZ version (-V).
856 Allow YAZ to use ICU 3.4.
858 Added new ICU test case which illustrates removal of diacritics.
860 --- 3.0.41 2008/12/29
862 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
864 --- 3.0.40 2008/12/29
866 For configure, using option --without-xml2 also disables Libxslt/Libexslt
869 Fixed bug #2352: yaz-marcdump crashes for certain record.
871 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
873 Added support for Danmarc2 to UTF-8 conversion.
875 Added support for ISO5426 to UTF-8 conversion.
877 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
878 implementation version.
880 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
882 --- 3.0.38 2008/11/10
884 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
885 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
887 ZOOM C now interprets databaseName option for ZOOM connection as path
890 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
892 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
894 Dummy Libxml2 types no longer defined in headers of YAZ'.
896 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
899 --- 3.0.36 2008/09/26
901 Various ODR chapter fixes.
903 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
905 Added missing source for Windows compilation, mutex.c.
907 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
909 For SRU connections in ZOOM all records up to "count" are now fetched.
911 Fixed crash in generic frontend server (and yaz-ztest) which occurred
912 in Windows due to bad error handling for Libxml2.
914 Added facility for sending arbitrary records (ASN.1 any) using
915 ZOOM C's Extended service update. Patch by Sam Reynolds.
917 New options for ZOOM C's connection, logapdu which makes ZOOM log
920 --- 3.0.34 2008/06/18
922 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
924 --- 3.0.32 2008/06/12
926 Fixed memory violation that could occur when decoding UTF-8. This bug
927 was only present in 3.0.30 of YAZ.
929 --- 3.0.30 2008/06/06
931 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
932 GNU TLS is used by default (if found).
934 yaz-ztest returns OPAC records if a client asks for OPAC.
936 Improved speed of MARC-8 encoding.
938 Added support for lossy and loss-less MARC-8 encoding.
940 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
942 Added new Windows Service wrapper (sc).
944 yaz-client's itemorder command may now send a file.
946 Fixed yaz-marcdump to allow the use of NS prefix for record element.
948 Added new function yaz_log_xml_errors.
950 Allow (but warn) unknown XML attributes in MARCXML parsing.
952 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
954 The UTF-8 to MARC-8 conversion now uses a different set of characters
955 for Greek symbols. Bug #2120.
957 --- 3.0.26 2008/02/21
959 Added yaz_daemon (daemon.h).
961 Fixed bug #2068: pkg-config trouble
963 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
965 --- 3.0.24 2008/01/28
967 Document --with-xml2 option.
969 Added OPAC XML XSD (etc/opacxml.xsd).
971 Allow glob mask for name attribute in retrieval element for the
972 generic frontend server's retrieval facility.
974 Changed yaz_poll_poll to return yaz_poll_except for all returned events
975 except POLLIN/POLLOUT.
977 Fixed error handling in cs_listen. Bug #2037.
979 --- 3.0.22 2008/01/20
981 Fixed version in yaz/yaz-version.h.
983 Fixed bug #2027: Crash when closing connection.
985 Changed configure so that ICU support is only enabled if only ICU
986 and Libxml2 is available (because the ICU chain is XML based).
988 --- 3.0.20 2008/01/15
990 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
991 is built. Only this DLL depends on the ICU runtime.
993 yaz-ziffy is no longer part of YAZ. It is distributed separately by
994 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
996 Changed license of CCL module to 'Revised BSD'. After consultation with
997 remaining members of the original EUROPAGATE consortium, we are re-issuing
998 the CCL module without a separate license. The software was developed by
999 Index Data as part of a research project. The special license was included
1000 to help feed usage information back to the project consortium to support
1001 project evaluation. At this time, the project consortium has long-since
1002 disbanded, and the majority of the original principals have retired. At the
1003 same time, we have significantly modified the software during the following
1004 years, to the point where very practically no original code remains. To
1005 simplify re-use of the software, we have contacted those members of the
1006 consortium who could be reached, and agreed to re-issue the module as a
1007 proper part of the YAZ package.
1009 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1011 CQL closer to being version 1.2 compliant. CQL also allows free-form
1012 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1015 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1016 bug could make Extended services handling crash in the ZOOM layer. This
1017 bug was only present in YAZ 3.0.18.
1019 --- 3.0.18 2007/12/19
1021 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1024 yaz-marcdump reads and writes collection wrapped records.
1026 Handle OPAC for record conversion module.
1028 Fixes for ICU wrapper.
1030 Allow ICU libs to be controlled with --with-icu .
1032 --- 3.0.16 2007/11/12
1034 Added yaz_poll which is a wrapper for select/poll. When poll is available
1035 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1036 sockets to be in use.
1038 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1039 functionality through an XML based configuration (ICU chain). This system
1040 is useful for search facilities such as Pazpar2 and Zebra that needs to
1041 perform tokenization of indexed material. The ICU code in a separate
1042 library libyaz3_icu.a.
1044 Added HTTP tunnel facility for COMSTACK, bug #1752.
1045 This is a facility that allows a Web proxy, such as squid, to tunnel
1046 Z39.50 traffic. This facility is "transparent" to must applications
1047 using YAZ. It's enabled by using pseudo transport connect: followed by
1048 the proxy address, followed by command, then follwed by he regular
1049 "virtual" addresss. For example,
1050 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1052 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1054 --- 3.0.14 2007/09/21
1056 Fixed bad memory reference in ZOOM_record - cuased by member not being
1057 initialized. This was a problem only in YAZ 3.0.12.
1059 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1060 fields were not removed.
1062 Changed the way C code is generated from codetables.xml. Made a MARC-8
1063 conversion trie for each characterSet section rather than codeTable.
1064 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1065 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1067 --- 3.0.12 2007/09/12
1069 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1070 from ZOOM_record_error).
1072 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1074 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1076 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1078 Better SRW-to-Bib-1 diagnostic mapping.
1080 ZOOM C and yaz-client announces SRU version 1.2 by default.
1082 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1085 Fixed in yaz_sru_decode to allow other version than 1.1.
1087 --- 3.0.10 2007/08/22
1089 Added support for SRU scan for ZOOM.
1091 Added support for the use of the older versions or Extended Service
1092 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1093 set to the version , 1=first, 2=second, 3=third. The third version is
1094 what ZOOM C has used so far. And that, obviously, is the default.
1096 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1097 therefore in Zebra and in SimpleServer-based applications). The new
1098 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1099 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1100 which is passed into the back-end search callback function.
1102 Added support for HTTP Basic authentication in clients: the SRU/W
1103 codec encodes the username/password elements of the PDU structure
1104 appropriately, and these may be set using the "user" and "password"
1105 options in ZOOM-C applications (the same options that are used for
1106 Z39.50 authentication).
1108 --- 3.0.8 2007/06/25
1110 Fixed bug #1208: SSL appears to be broken in ZOOM.
1112 Fixed bug #1206: Libxml2 include path weirdness.
1114 Added oid_name_to_dotstring.
1116 Allow elementSetName to be specified for ZOOM C record update.
1118 Allow waitAction to be specified for ZOOM C based for Extended Services.
1120 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1121 syntax OID. Bug introduced in YAZ 3 series.
1123 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1125 --- 3.0.6 2007/06/06
1127 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1128 directory. yaz-client now reads commands from file given by option -f
1129 if specified; then tries to read .yazclientrc in current directory.
1130 Failing that, it reads .yazclientrc from user's home directory.
1132 Added support for correlationInfo Note and ID for Record Update via
1135 Added yaz-client command querycharset which specifies character set for
1136 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1137 (termListAndStartPoint).
1139 Charset ISO5428:1984 is an alias for ISO5428-1984.
1141 Implemented a way to perform scan in a result set using Z39.50. This
1142 is achieved by attaching the result set name in the characterInfo
1143 (type InternationalString) of OtherInformation in the Scan Request PDU.
1144 The result set is identified in the otherinformation by the new OID:
1145 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1146 This allows for scan in result set and faceted search . Zebra did some
1147 of this in the APT term using attribute type 8 and value being result
1148 set. Using the OtherInformation approach for this is cleaner and easier
1149 to work with in proxies and the like. This facility can be used in
1150 yaz-client using new command setscan which takes a result set as first
1151 argument, start position (APT) as second.
1153 Changed decoding of SRU XML packed records to deal with servers that
1154 have recordData with XML data with multiple root nodes. Also make
1155 comparison for recordPacking case insensitive. Again, one server
1156 returns "XML" where others return "xml".
1158 For SRU responses allow Content-Type application/xml as well as text/xml.
1160 --- 3.0.4 2007/05/21
1162 Fixed bug in character set conversion of BER strings. Bug introduced
1165 --- 3.0.2 2007/05/08
1167 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1169 For OID class, use oid_class consistently.
1171 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1174 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1175 character set for bibliographic information interchange". By Giannis Kosmas.
1177 Added documentation on new OID API.
1179 --- 3.0.0 2007/05/02
1181 Changes to generic frontend server interface: added new member
1182 'query_charset' for bend_initrequest structure. A backend init handler
1183 should set this member to its native character set for query terms.
1184 When defined, the frontend server logic will announce this character set
1185 to a client if the negotiationModel bit is set by the client. All server
1186 implementors are encouraged to specify this. If a backend server does not
1187 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1189 Added CCL utility to remove terms (stop words) from resulting RPN
1190 tree. This is handled by functions with prefix ccl_stop_words_ .
1192 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1193 terms in RPN queries.
1195 Clean-up the CCL API. Moved some internal structures from ccl.h to
1196 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1197 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1198 This is replaced by ccl_parser_find_str which takes a string instead.
1200 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1201 libyaz.la is the core of YAZ except the generic frontend server and
1202 does not depend on POSIX threads anymore. libyaz_server.la is the
1203 generic frontend server facilities and uses POSIX thread functionality
1204 if available. The libyaz.la no longer depends on POSIX threads because
1205 the number of global structures is limited. NMEM no longer re-uses blocks
1206 between threads ; it simply free's memory immediately but allocates in
1207 "large" chunks as usual. We don't expect any performance penalties
1208 because of this. The yaz_log system is still using a global log_level so
1209 caution must be taken when modifying it with yaz_log_init_.. +
1210 yaz_log_mask_str. This, however, should not cause any trouble because
1211 these functions are called during initialization of application code
1212 anyway. `yaz-config --libs server` returns libs for server applications;
1213 `yaz-config --libs` returns libs for non-server applications.
1215 New OID database - with public definitions in oid_db.h. Removed old OID
1216 database including the head oid.h and definitions such as enum oid_value
1217 and struct oident. The new OID database uses the same string names as
1218 before but the 'protocol' is gone. There are now only two representations
1219 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1220 converts from string to OID; functions with prefix yaz_oid_to_string
1221 converts the other way.
1223 Change to emit_term() in CQL-to-PQF query translation: when a term has
1224 the /regexp relation modifier, do not process it for leading and
1225 trailing "^" and "*", which have quite different meanings in regular
1228 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1229 write handlers no longer carries a 'last' parameter. This will make
1230 yaz_iconv flush "less" characters. A flush is performed by call to
1231 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1233 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1234 removed, because function yaz_query_to_wrbuf does the same.
1236 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1237 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1239 Deprecated MARC utility functions removed.
1241 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1244 Branch split: YAZ_2_1_55_branch
1246 --- 2.1.54 2007/03/16
1248 Fix to ZOOM-C so that transparent reconnection is properly handled on
1249 connections that are in asynchronous mode.
1251 Fixed compilation on OpenBSD 4.0.
1253 Large strings in GRS-1 records are now properly displayed in yaz-client.
1255 Added character conversion support for "advancegreek"; based on patch from
1258 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1259 sequence is met. Before the error was not set so it would be unknown.
1261 Adjust yaz-marcdump MARC reader so that it skips until record separator
1264 --- 2.1.52 2007/03/07
1266 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1267 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1268 fd_set structure used as a bitmask for the FDs to be selected on.
1270 Using ACX_PTHREAD macro to check for POSIX threads.
1272 Fixed have-vsnprintf check.
1274 --- 2.1.50 2007/02/23
1276 Fixes for configure on BSD. Bug #900.
1278 Added snprintf/vsnprintf wrappers for systems that don't have
1279 limits (heavens forbid).
1281 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1282 created before all previous tasks were completed and removed from the
1283 task queue, the new task could be removed by a mistake.
1285 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1287 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1289 Fixed bug #832: Problem with MARC/charset in yaz-client.
1291 Fixed bug #668: save command line history for yaz-client.
1293 Fixed bug #830: pkg-config support.
1295 --- 2.1.48 2007/01/23
1297 Extended ZOOM result set options with two options that may be read by
1298 a client: resultSetStatus and presentStatus with values as specified for
1300 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1302 Fixed bug #827: Using SSL fails on Debian etch.
1304 Fixed bug #826: Weird looking chars for set of MARC records.
1306 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1307 that is treated as an ItemOrder with itemRequest being an XML document
1308 external. The value of "doc" is the content.
1310 Extended the GFS search facility. New member of bend_search_rr
1311 'estimated_hit_count' signals that hits is known to be an estmate
1312 (higher or lower than real hit count). New member 'partial_resultset'
1313 signals that the search was partial (hit count is lower or equal than
1314 real hit count). For Z39.50, the information is stored in resultSetStatus
1315 member of SearchResponse APDU. For SRU, the information is signalled
1316 via SRU diagnostic 59: "Result set created with valid partial results
1319 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1321 --- 2.1.46 2007/01/13
1323 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1325 Added ZOOM_connection_peek_event.
1327 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1328 the following new functions:
1329 ZOOM_event_nonblock, ZOOM_connection_process,
1330 ZOOM_connection_get_{socket,mask,timeout},
1331 ZOOM_connection_fire_event_{timeout,socket}.
1332 The existing blocking event handler, ZOOM_event, is a wrapper for the
1333 + blocking ZOOM_event_sys_{poll,select}.
1335 Implemented function ccl_xml_config which parses XML version of CCL
1336 configuration (bug #798).
1338 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1340 Added timings utility (yaz/timing.h)
1342 --- 2.1.44 2007/01/03
1344 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1347 Fixed bug #779: Rotation of apdu.log fails.
1349 Fixed for character set conversions:
1350 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1351 Honor G1 set in MARC-8 decoding.
1353 --- 2.1.42 2006/12/17
1355 Fixed bug #775: char conversion does not handle Alternative UTF-8
1358 Implemented function yaz_marc_read_line which parses MARC line format
1359 records. There is a wealth of formats out there. So far, this function
1360 reads line records produced by yaz_marc_write_line.
1362 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1363 more generic and easier to remember(!) options: -i format and -o format
1364 which specifies input format and output format respectively - where
1365 format is one of "marc", "marcxml", "line", "marcxchange".
1367 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1368 does not print anything except warnings for records.
1370 For yaz-marcdump, added support for MARC split into files (-s) with a given
1373 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1374 spec, at http://www.loc.gov/standards/sru/record-update/
1375 This has changed the binary layout of the following structs:
1376 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1377 bend_update_rr . Patch by Ko van der Sloot.
1379 Added GFS utility function bend_assoc_is_alive which returns 1 if
1380 association is still alive (client is connected); 0 otherwise (client
1381 closed connection). This allows busy servers to stop working for
1384 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1385 been a separate piece of software. This version of ziffy has been modified
1386 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1388 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1390 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1391 Client code may now interrogate options such as "init_opt_sort" to
1392 find out whether the server claims to support various options.
1394 --- 2.1.40 2006/11/27
1396 Added utilities yaz_{set,get}_esn to set/get element set name from
1399 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1400 of YAZ and has been so since YAZ 2.1.10.
1402 Implemented ZOOM_record_error which returns error information for
1403 record (surrogate diagnostic).
1405 --- 2.1.38 2006/10/31
1407 Updates for SRU Update by Ko van der Sloot:
1408 1. Changed name from "operation" to "action"
1409 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1410 versions in the code, marked as 'backward compatible'.
1411 3. Added diagnostics for SRU Update.
1413 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1415 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1417 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1419 For GFS, fixed problem with SRU diagnostic 'First record position out of
1420 range' being issued for 0 hits.
1422 zoomtst10 part of Windows Build.
1424 --- 2.1.36 2006/10/13
1426 Implemented yaz_filepath_comp which splits a path into file path
1427 components (required by Zebra 2.0.3+).
1429 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1430 BSD inspired license until now so this should not have any real impact on
1431 anybody. See http://www.opensource.org/licenses/bsd-license.php
1433 Fixed bug #687: Missing log lines.
1435 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1438 Fixed bug #689: SRU diagnostics to be added.
1440 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1441 whether a connection is idle (no more work do do).
1443 --- 2.1.34 2006/10/04
1445 Change type of optval from long to int for invocation of setsockopt with
1446 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1448 Added support for specifying the max log file size for the Generic
1449 Frontend Server. The size is given with option -r.
1451 --- 2.1.32 2006/09/21
1453 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1455 --- 2.1.30 2006/09/17
1457 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1460 Fixed bug in Generic Frontend Server that could cause a server to stop
1461 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1463 For the generic frontend server, the maximum record size is used as maximum
1464 size of incoming packages (SRU + Z39.50). The value until was previously
1465 only used in Z39.50 Init negotiation and, later, in a session controlled
1466 sizes of records returned. This is controlled using -k option. It can be
1467 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1469 --- 2.1.28 2006/09/04
1471 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1474 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1476 New option for yaz-marcdump -lpos=value which allows setting a portion
1477 of MARC header to a certain value.
1479 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1481 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1482 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1484 --- 2.1.26 2006/08/15
1486 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1489 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1491 --- 2.1.24 2006/08/08
1493 Fixed MARC ISO2709 encoding routines to deal with character set
1496 Minor changes to GFS logging. Database included in search request log
1499 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1500 cached/multiple records.
1502 Shared libraries are built by default on Unix+configure.
1504 Changed cql2pqf transformation to use a different evaluation order. The
1505 new order is: always, relation, structure, position, truncation, index
1506 and relationModifier. Old order was: always, relation, relationModifier,
1507 structure, index, position, truncation. Note that the the latter ones
1508 override former ones for identical attributes.. The new scheme means that
1509 it is possible to override any existing attribute with a relationModifier.
1510 And also that it is possible to override everything for the index rule
1511 (except the ones listed in relationModifier). No order is perfect but this
1512 one, we believe, covers more real cases.. The "always" should have been
1513 called "default", since the attributes there can be overridden with all
1516 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1517 compilation phase, but also for yaz-config --cflags output. This allows
1518 us to have public headers with Libxml2 stuff in them . It should also,
1519 eventually, make Libxml2 checks redundant in packages using YAZ, such
1522 --- 2.1.22 2006/06/15
1524 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1525 stored in uri, message and details.. Previously diagnostics were stored
1526 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1527 compatibility.. but he's probably the only one affected, so.
1529 Added support for CCL, compiled on the client side, in ZOOM-C. This
1530 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1531 input; the resulting query objects can be used for for searching with
1532 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1534 YAZ' configure searches for OpenSSL by default.
1536 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1537 SL_CTX_use_certificate_file. See
1538 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1539 for more info. Thanks to Ko van der Sloot.
1541 --- 2.1.20 2006/06/02
1543 Bug #600: SRU GET, POST support for yaz-client. Introduced
1544 command 'sru' which selects method SOAP/GET/POST.
1546 Allow missingValueAction to be specified for the sortspec string -
1547 function yaz_sort_spec. By default, the missing value action is null.
1548 Use ! to specify "abort". Use = followed by stringvalue to specify default
1551 Ensured that Present-handler (if defined) is called in GFS before any call to
1552 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1553 searchRetrieve requests.
1555 Documentation for YAZ is now based on the Docbook XML/XSLT using
1556 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1557 is no longer depending on jade/openjade or docbook-to-man scripts.
1558 PDF is no longer part of the distribution - but can optionally be
1559 made using DSSSL/jadetex or FOP.
1561 Added retrieval handling support in Generic Frontend Server to support
1562 conversion between MARC/XML as well as XSLTtransforms. See
1563 etc/yazgfs.xml for an example.
1565 Added Authentication support to Generic Frontend Server in SRU
1566 mode. Authentication using HTTP Basic is supported, as is the use
1567 of 'x-username' and 'x-password' parameters in the request itself.
1569 Added support for a new character set MARC8s identical to MARC8 except
1570 that it converts combined characters to single Unicode characters in the
1571 Latin-1 range (when possible).
1573 --- 2.1.18 2006/04/24
1575 ASN.1 compiler 0.4: generates brief Doxygen file header for
1576 generated .h/.c files.
1578 Utility yaz_iconv now supports conversion to MARC-8.
1580 New facilities for the MARC module. The reading - and writing of
1581 content are separate methods for the yaz_marc_t handle. The following
1582 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1583 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1584 format). Write functions have prefix yaz_marc_write_.. The existing
1585 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1586 available. Removed support for OAI-MARC and simplexml (not the
1587 simplexml from PHP5).
1589 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1590 to be returned for this connection.
1592 --- 2.1.16 2006/03/31
1594 Allow multiple languages and charsets to be specified with
1595 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1596 negcharset iso-8859-1,utf-8
1598 Translation of proximity nodes from CQL into PQF now works.
1600 Moved to automake 1.8, 1.9.
1602 Added function yaz_log_set_handler which allows a log handler to be
1603 installed. This handler will be called for all log messages. Output
1604 to file is also produced; but that can be disabled by passing NULL
1605 fname to yaz_log_init_file.
1607 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1609 For SRW (including GFS), accept application/soap+xml as content-type
1612 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1613 produces NO stylesheet reference even if a default stylesheet is specified
1616 --- 2.1.14 2006/03/14
1618 Updated Windows package to include yazd.dll + yazd.lib for the
1619 Development component.
1621 If the environment variable YAZ_LOG is set, then it is used as a
1622 string indicating the default level of logging to use if not
1623 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1624 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1625 used as before. So, for example, to omit warnings from YAZ logging,
1626 export YAZ_LOG=-warn
1628 cql_transform() now map structure and other attributes before indexes,
1629 so that index-specific structures and other attributes can override
1630 defaults. So now a combination of mapping specifications such as:
1632 index.dc.date = 1=date-modified 4=5
1633 does the right thing.
1635 cql_transform() now also respects the "always" mapping specification,
1636 which establishes an initial set of attributes to be used for all
1637 terms except where overridden by more specific attributes associated
1638 with the index, relation or modifier.
1640 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1641 which mode to use; one of "post", "get" or "soap" (SRW, default).
1643 Fixes for yaz_iconv routines: changed trie-based character set conversions
1644 to use only non-negative values for bit fields due to Sun's C compiler not
1645 supporting negative values.
1647 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1648 sequences where not read correctly. Fix by Rustam Usmanov.
1650 Updated win/makefile to use options, settings which makes things
1651 compile with VS C 2005.
1653 --- 2.1.12 2006/02/01
1655 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1657 In ZOOM socket code, use select instead of poll on MacOSX.
1659 ZOOM-C now support client-side compilation of CQL into RPN that is
1660 sent to the server, enabling CQL to be used against all Z39.50
1661 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1662 ZOOM_query object, and submit it using ZOOM_connection_search().
1663 The CQL-to-RPN translation uses a configuration file, the name of
1664 which must be specified in the Connection's "cqlfile" option.
1666 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1667 function, which takes as its start-term parameter a ZOOM_query object
1668 (which may have had either CQL or RPN set into it).
1671 --- 2.1.10 2005/11/29
1673 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1674 GFS to support this as well. Backend handler, bend_srw_update, does the
1675 update work. Code contributed by Ko van der Sloot.
1677 Allow retrieval of Search Result-1 information in ZOOM by the use of
1678 options that are attached to a result set. ZOOM documentation updated
1681 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1682 UTF-8 conversion. Patch by Raj Patel.
1684 Added option -m to GFS to control formatting of timestamps in log file.
1686 Added 'exit' as synonym for 'quit' in yaz-client
1688 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1689 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1690 for the new members. Patch by Ko van der Sloot.
1692 Added support for SRU POST. It is supported for content-type
1693 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1695 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1696 Instead make the library libyaz.la multi-threaded. Threading as a whole
1697 can still be disabled by configure option --disable-threads. Previosly,
1698 with older GLIBCs there were problems with MT libs under Apache. This
1699 has now been fixed a long time ago.
1701 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1704 CQL module modified to be case insensitive for relations/indexes/operations.
1706 Fixed bug in CQL transform code: incorrect value relationModifieder
1709 Added 'show all' command for yaz-client which retrieves all results
1712 Added new yaz-client, xmles, which takes a (private) OID and
1713 a document to be sent as an extended service request.
1715 Describe new yaz-client commands wait_response and set_auto_wait.
1717 Increase TCP/IP listener backlog from 3 (which I am guessing was
1718 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1719 that the socket will queue as many incoming connections as it's able
1720 to handle ongoing connections. In other words, it will never now
1721 refuse a connection that it would be able to handle merely because
1722 it's not got around to accepting() enough of the pending connections
1723 yet. This is the behaviour anyway under Linux, where the listen()
1724 argument is ignored; but not under BSD and on systems such as
1725 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1726 YAZ-based servers should now be uniform across operating systems in
1729 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1730 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1731 This allows yaz-marcdump to read large MARC batches (>2 GB).
1733 Modified all YAZ source files - except the source which is auto-generated
1734 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1737 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1738 corresponding to the existing *_setl() function. These allow option
1739 values containing arbitrary valuues.
1741 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1742 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1743 except that it returns an indicator of whether or not the sort
1744 criterion was accepted (0 for OK, -1 for invalid).
1746 --- 2.1.8 2005/06/07
1748 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1749 MARC output rather than returning "new" buffer.
1751 yaz-client warns about unknown init options.
1753 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1755 --- 2.1.6 2005/05/24
1757 Added support for SRW sort in Generic Frontend Server. Patch
1758 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1759 sortKeys - or NULL if none is provided.
1761 Fixed bug #307: It was impossible to specify indefinite/no timeout
1762 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1765 Added support for multiple languages and charsets to be specified in
1766 ZOOM. Each charset/language is separated by a blank. If negotiation is
1767 in effect in init-response, Option
1768 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1769 Code based on patch by Vasiliy Osadchuk.
1771 Fixed bug #306: infinite recursion that occurred when calling
1772 yaz_log_level_init as the first call (before other log level or
1775 Fixed bug in scan handling in front end server: if preferred-Position-In-
1776 Response was non-present, a NULL pointer referece was performed.
1778 --- 2.1.4 2005/04/26
1780 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1781 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1782 now defined for all those error codes. So instead of putting 109 in
1783 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1784 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1786 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1789 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1791 Program yaz-client now exits and produces an error message if multiple
1792 Z39.50 servers are specified on the command line (none or one allowed
1795 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1798 --- 2.1.2 2005/03/16
1800 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1802 Fixed bug #272: Preserve spacing for CCL terms.
1804 --- 2.1.0 2005/03/14
1806 Added support for virtual hosts and multiple backend servers for
1807 the YAZ frontend server. The configution is XML based and
1808 support specificition of CQL to RPN mappings and explain information.
1809 See section "Virtual Hosts" in the YAZ manual.
1811 Extended OPAC display utility. OPAC display utility renders
1812 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1813 to supplement yaz_marc_decode_wrbuf.
1815 Fixed a bug in MARC decoder that could caused it to crash for some
1816 invalid MARC records. More diagnostics and warnings where added in
1817 XML output (warnings, etc are stored in comments).
1819 --- 2.0.34 2005/02/08
1821 Fixes for UNIX domain sockets. Bug #261.
1823 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1825 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1826 Added yaz_marc_subfield_str which defines subfield lead string which is
1827 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1828 yaz_marc_endline_str which defines end of fields string used in
1829 YAZ_MARC_LINE format. Default string is newline.
1831 Experimental support for MarcXChange. This format can be produced
1832 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1833 http://www.bs.dk/standards/MarcXchange.xsd
1835 Added yaz-client commands scansize that sets maximum number of
1836 entries to be returned by scan.
1838 --- 2.0.32 2005/01/11
1840 Added support for SRW scan in yaz-client and Generic Frontend Server.
1842 * Added whereInList member to SRW Scan Term.
1844 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1846 Fixed NMEM system to return aligned blocks on the smallest boundaries
1847 that are suitably aligned for all possible types on the particular
1848 architecture YAZ is being built for.
1850 --- 2.0.30 2005/01/04
1852 Fixed numerious warnings that was issued with newer versions of GCC.
1854 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1855 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1858 Make YAZ Generic Frontend Server slightly faster.
1860 Enhance (and reduce) logging for Generic Frontend Server.
1862 Revert YAZ log system so that it flushes every write operation
1863 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1865 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1866 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1867 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1868 will effectively disable old definitions.
1870 --- 2.0.28 2004/11/09
1872 Added yaz_log_time_format which specifies log format using
1875 Added yaz_log_module_level which returns mask for a module. Value
1876 is non-zero mask a if module is enabled; zero if disabled.
1878 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1879 in include/yaz/cql.h.
1881 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1883 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1885 Fixed bug #172: RPM builds does not enable SSL.
1887 Doxyfile.in part of dist. Doxyfile generated by configure.
1889 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1890 are given and the corresponding component does not exist.
1892 Extend CCL documentation in YAZ reference. Describe r=r.
1894 --- 2.0.26 2004/10/01
1896 Fixed MARC->MARCXML conversion to properly deal with
1897 fields, subfields, indicators having non-ASCII characters.
1899 Fixed MARC->MARCXML conversion so that ASCII control characters
1900 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1903 Added YAZ GFS support for conversion from Z39.50 surrogate
1904 diagnostics to SRW surrogate diagnostics.
1906 Bug fix: YAZ GFS did not return schema in explainResponse.
1908 --- 2.0.25 2004/09/30
1910 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1911 now converts recordSchema to elementSetName as well as schema URI.
1913 Fixed bug in COMSTACK that prevented HTTP request packages from being
1916 --- 2.0.24 2004/09/29
1918 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1919 does not require white-space before and after the dash in a range, e.g.
1920 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1923 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1924 due to new GCC removing "redundant" code.
1926 Added yaz-client commands scanpos and scanstep that sets preferred
1927 position and step-size for scan.
1929 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1931 Added CCL utility ccl_qual_buf which parses one or more CCL
1932 spec lines in a buffer.
1934 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1935 of name and value - ignoring empty lines and comments.
1937 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1939 Added odr_get_element_path which returns current element path for an
1940 ODR handle. This utility is useful in error handling or user-defined
1943 Added ODR_PRINT utility odr_set_stream which is is a more generic
1944 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1945 to a write function and pointer to close function. The close function - if
1946 non-NULL - will be called during odr_destroy.
1948 Fixed bug in CCL parser where truncation char was not removed from
1949 right side when truncation=both was in effect.
1951 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1954 --- 2.0.23 2004/08/11
1956 Fix buffer overrun in CQL parser when dealing with proximity (%).
1958 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1959 to UTF-8/UCS conversion is now only based on codetables.xml.
1961 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1963 --- 2.0.22 2004/08/06
1965 Add support for more "commit changes" in ZOOM (uses Extended Services).
1967 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1970 Yet another small fix for configure of SSL.
1972 --- 2.0.21 2004/05/14
1974 Fix SSL libs for configure when --with-openssl=DIR is given.
1976 --- 2.0.20 2004/05/10
1978 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1980 SSL comstack now uses yaz.pem certificate file on server side
1981 by default. Certificate filename can be configured by calling
1982 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1984 Fix bug regarding multiple calls to ZOOM_connection_connect.
1986 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1988 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1989 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1991 ZOOM now allows inspection of X509 peer certificate for verification.
1992 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1994 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1995 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1996 as "modular" but it simplifies things.
1998 Added cs_get_peer_certificate to that returns peer X509 PEM.
2000 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2001 NULL if SSL is unavailable.
2003 Documentation about MARC decoding tools.
2005 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2007 --- 2.0.19 2004/03/30
2009 Rename CHANGELOG to NEWS to follow GNU style packing.
2011 Fix bug with missing initialization of member in init_diagnostics.
2012 This bug affects threaded version of GFS server.
2014 --- 2.0.18 2004/03/20
2016 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2019 Ensure zlib.dll is packed with Windows install.
2021 --- 2.0.17 2004/03/17
2023 Fix encoding of xsd:string to use text instead of CDATA.
2025 Fix endless loop in CQL parser with unbalanced ".
2027 Use a more compact way to store MARC-8 conversion tables.
2029 --- 2.0.16 2004/03/16 Debian only
2031 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2034 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2039 --- 2.0.15 2004/03/01
2041 Another fix for decoding of XML packed records.
2043 --- 2.0.14 2004/02/25
2045 Fixes for Chunked encoding. White space not ignored after length spec.
2047 Update NS and use default NS for SRW diagnostic elements.
2049 --- 2.0.13 2004/02/23
2051 Implement ZOOM_resultset_cache_reset which resets record cache.
2053 Implement ZOOM_resultset_sort which sorts a result set.
2055 Implement chunked HTTP transfer.
2057 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2059 --- 2.0.12 2004/02/16
2061 Added member 'schema' to bend_explain_rr structure so that backend
2062 can specify explain record identifier. Defaults to Zeerex 2.0.
2064 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2066 --- 2.0.11 2004/02/16
2068 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2071 Added init command for yaz-client which sends "extra" init request.
2073 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2074 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2076 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2078 Make ZOOM error code for "invalid query".
2080 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2082 --- 2.0.10 2004/02/05
2084 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2087 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2089 Added option -p <file> to make Generic Frontend Server to write PID file.
2091 Added option -D to put Generic Frontend Server in background on its own.
2093 Make ZOOM C recognize option "password". If unset, "pass" is used
2094 (for backwards compatibility).
2096 Fixed a bug in Generic Frontend Server that could make it crash if a
2097 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2100 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2101 Must be issued before open, in order to be in effect.
2103 --- 2.0.9-6 2004/01/12 Debian/Windows
2105 Make the SRU server more picky WRT unknown params, etc.
2107 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2109 New YAZ client command, options, that sets Z39.50 options.
2111 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2112 options from a string of tokens (one token for each option bit).
2114 Update SRW diagnostic code messages.
2116 --- 2.0.9-5 2004/01/07 Debian/Windows
2118 Handle user defined stylesheet for SRW/SRU.
2120 --- 2.0.9-4 2004/01/06 Debian/Windows
2122 Fix bug in decoding of Content-Length.
2124 --- 2.0.9-3 2004/01/06 Debian/Windows
2126 Fix a bug with decoding of XML packed records.
2128 --- 2.0.9-2 2004/01/05 Debian only
2130 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2132 Fix bug in SRW/SRU diagnostics decoding.
2134 --- 2.0.9 2004/01/05
2136 Fixed bug in Generic Frontend Server which could drop records exceeding
2137 preferred message size. Reported and fixed by Irina Dijour.
2139 Fixed calculation of package size for structured records in Generic
2140 Frontend Server. Reported and fixed by Irina Dijour.
2142 Fixed namespace for SRW/SRU diagnostics.
2144 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2146 --- 2.0.8 2003/12/22
2148 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2149 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2152 CQL changes to reflect recent changes to the specification:
2153 * Documentation talks about context sets instead of index sets.
2154 * Documentation talks about indexes instead of qualifiers.
2155 * The CQL-to-PQF transformer's configuration file now uses
2156 "index.set.name = <attributes>" instead of the old form
2157 "qualifier.set.name = <attributes>". (Both forms are still
2158 understood but the latter is deprecated.)
2159 * CQL terms with no explicit index specified are now interpreted as
2160 cql.serverChoice instead of srw.serverChoice (which of course
2161 behaves exactly the same.)
2163 --- 2.0.7 2003/12/16
2165 MARC conversion can now generate ISO2709 output in another
2166 character set. yaz-marcdump uses this facility if you invoke it
2169 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2170 functions from there can be used from C++.
2172 --- 2.0.6 2003/12/04
2174 Frontend server now transfers memory from decoded packages to stream
2177 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2178 references to show up.
2180 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2181 the ZOOM Abstract API. The older names for the same options are still
2182 also supported for the benefit of old applications.
2184 ZOOM-C supports "implementationId" and "implementationVersion" options
2185 to go along with "implementationName". These allow the user code to
2186 specify identification strings to be sent to servers.
2187 Add OID for the new ExtLite attribute set.
2189 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2190 as requested/supplid by Ere Maijala <ere@atp.fi>
2192 For generic frontend server, reverse the order of
2193 "toolkit-supplied / application-supplied" strings sent as implementationId,
2194 Name and Version. Also, remove the spaces around the slash. This brings
2195 the GFS in line with the behaviour of ZOOM-C on the client side.
2197 Add function ZOOM_scanset_display_term.
2199 yaz-client shows scan displayTerm if present.
2201 Utility yaz-iconv is now installed by default along with the man page
2204 Extend configure check for OpenSSL to use pkg-config where available (such
2207 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2208 server to specify uid/gid/mask for socket using the format
2209 unix:[user=uid,][group=gid,][umask=mask,]file=path
2210 If file= is omitted the existing format is assumed, e.g.
2212 in which case the mask is 0666 (rw for everybody).
2214 Major restructure of YAZ source. All source in libyaz is in src directory.
2215 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2216 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2218 Added man page for utility yaz-marcdump (used to be called marcdump).
2219 yaz-marcdump is installed by 'make install'.
2221 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2222 of incoming package failed.
2224 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2226 Change prototype of odr_perror: add const to message string.
2228 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2230 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2231 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2232 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2233 DNS lookup. There should not be any compatibility problems with this
2234 assuming that blocking=1 or 0 is used.
2236 Fix bad reference in UNIX comstack in function cs_addrstr.
2238 Fix for compilation on AIX.
2240 The generic front-end server (server/seshigh.c) now supports returning
2241 Init diagnostics to the client in User-information-field, in
2242 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2245 --- 2.0.4 2003/09/04
2247 Allow any CQL relation (not just all,any,exact,scr).
2249 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2250 that features the same UI.
2252 Implemented command update0 in YAZ client which is equivalent to
2253 update but uses old of Ext Update ASN.1.
2255 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2256 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2257 Previously no OID was used for this info.
2259 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2260 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2261 returns 'malformed search term' otherwise.
2263 SortResponse member resultCount now set to NULL in sort handler of
2266 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2269 Add three new utility functions for translating OIDs between various
2270 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2271 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2272 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2273 char *oid_to_dotstring(const int *oid, char *oidbuf);
2274 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2276 Reverted modifications for ES Update definition for z_IU0Update
2277 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2278 is back to YAZ 2.0.2.
2280 String value attributes for CCL parser.
2282 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2283 which their FirstSearch server returns in Init responses, sometimes
2284 carrying useful diagnostic information when Init fails. This has the
2285 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2286 "z39.50/oclcui.asn", where its definition is somewhat different from
2287 what OCLC document on their web-site, as required to interoperate with
2290 Support for anonymous authentication in yaz-client. Use the command
2293 * Fix the OID of the Index Data-local "admin" Extended Service from
2294 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2295 the 1000, which indicates a locally-defined OID, was a mistake.
2297 --- 2.0.3 2003/06/20
2299 Fix CCL directive @case handling so that it affects string match for
2300 both CCL keywords and qualifiers.
2302 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2303 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2304 Decoder has been updated with ASN.1 changes as listed in
2305 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2306 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2307 z_IUUpdate, remains unchanged.
2309 ZOOM_record_get may now return a record in a specific character set.
2310 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2311 "from" is the character set of record as returned by target. "to" is
2312 the character set to be returned. If omitted, "to" is UTF-8.
2314 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2316 New ODR utility, odr_getelement, which returns name of element for
2317 which encoding/decoding failed.
2319 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2320 in cases where a required element was omitted.
2322 Bug fix: some MARC8 sequences were not converted.
2324 New ZOOM option "step" which specifies number of records to be
2325 retrieved in one chunk. Used in conjunction with "start" and "count".
2327 SRW support for yaz-client. Use scheme http: to use it, e.g.
2330 yaz-client no longer does (un)intelligent character set conversions
2331 by default. Can be enabled with charset and marc_charset commands.
2333 xmalloc trace fix for 64-bit systems such as DEC alpha.
2335 Solaris 2.6 compile fix.
2337 New function, cql_strerror() translates SRW error codes, as returned
2338 by cql_transform_error(), into human-readable English strings. Used
2339 in yaz-client diagnostics when appropriate.
2341 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2342 converts it into a type-1 query which is sent to the server. This
2343 makes CQL available for use with all Z-servers, as opposed to the tiny
2344 minority that can handle CQL queries themselves.
2346 --- 2.0.2 2003/04/28
2348 New Debian package layout similar to the Redhat Package layout.
2350 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2351 and search result respectively.
2353 --- 2.0.1 2003/04/25
2355 Redhat package is now several packages: libyaz (runtime libraries),
2356 libyaz-devel (development and documentation, and yaz (utility programs).
2357 Package spec file by Morten Bogeskov.
2359 New member 'schema' in struct bend_fetch_rr which the name of requested
2360 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2361 handler MAY set this to reflect the schema of the returned record.
2363 New member 'display_term' in struct scan_entry. GFS now sets member entries
2364 and allocates scan entries to be filled by user scan handler. In previous
2365 version, entries member was allocated by the scan handler. That still works,
2366 but the GFS will ignore member display_term - assuming it was NOT set by
2367 the handler. The fact that the GFS now allocates the entries both allows
2368 for new members and makes a scan handler easier to write.
2370 Fix CQL lex buffer overflow.
2372 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2373 SRU default recordPacking is string.
2375 SRU protocol support for frontend server.
2377 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2379 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2381 Added scan for the ZOOM shell (zoomsh).
2385 * String Identifers for Schemas (Amendment 5).
2386 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2387 Old definition for schema
2388 Odr_oid *schema; /* OPT */
2393 Z_InternationalString *uri;
2394 #define Z_Schema_oid 1
2395 #define Z_Schema_uri 2
2398 * resultCount parameter to Sort Response (Amendment 1).
2399 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2401 Support for SRW 1.0 over HTTP. This is an optional feature and
2402 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2405 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2406 on the same port. SRW SearchRetrieveRequests are mapped
2407 to bend_init,bend_search,bend_fetch,bend_close.
2409 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2411 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2412 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2414 ZOOM connections are SRW based if schem http is used for hostname
2415 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2416 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2418 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2419 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2420 distance=n, order=true/false, relation=le, prox unit=word. If
2421 n is omitted, distance 1 is used.
2423 Fixed problem with C compiler include path in wrong order.
2425 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2426 on Solaris. Patch from Ko van der Sloot.
2428 New MARC decode API. All new functions operate on a yaz_marc_t
2429 handle. The most important new functions are: yaz_marc_create,
2430 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2431 decode and destroy respectively. Decoder can produce formats
2432 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2433 include/yaz/marcdisp.h.
2435 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2436 to UTF-8, UCS-32, wchar_t or Latin-1.
2438 * Prototypes for yaz_iconv_-functions moved to separate header
2439 include/yaz/yaz-iconv.h.
2441 Make a few private functions 'static' in unix.c. This prevents
2442 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2444 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2445 are set when Init Response is received.
2447 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2448 but returns diagnostic set as well.
2450 New function yaz_strerror which is a portable wrapper for
2451 strerror/strerror_r/GetLastMessage.
2453 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2454 is returned for MARC. If type is "oai", then OAI MARC is returned.
2456 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2459 --- 1.9.2 2002/11/26
2461 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2463 Fix bad race conditions on SIGTERM and terminate gracefully in
2466 Move retrieval (data1) module to Zebra since nobody seems to be
2469 Add GRS-1 render for ZOOM using same format as yaz-client.
2471 --- 1.9.1 2002/10/05
2473 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2475 Fix broken ESpec handling in data1 module.
2477 SGML reader parses comments and makes them part of the data1 tree.
2479 Added several type casts so that YAZ compiles as C++ code.
2481 ZOOM didn't handle PDU encoding failures properly.
2483 Added more Bib-1 diagnostics (approved extensions).
2485 GNU configure: better check for iconv.
2487 More portable use of accept, getpeername. Check for socklen_t. Use
2488 int/size_t if socklen_t is not defined.
2492 PQF parser rejects bad queries - including those with extra
2493 characters in them. PQF parser used to silently ignore that.
2494 Cleaner API for PQF added, which allows you to get detailed
2495 error information for bad queries (see yaz/pquery.h).
2497 Fixed bug in ZOOM_record_get for type "database".
2499 Implemented mini iconv library supporting conversions between
2500 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2502 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2504 --- 1.8.9 2002/08/20
2506 Fixed ZOOM C record cache so that preferredRecordSyntax and
2507 elementSetName is used to check for already fetched records.
2509 --- 1.8.8 2002/08/02
2511 Added three members in bend_initrequest structure to facilitate
2512 character set negotiation.
2514 Fixed a bug in frontend server that could cause indefinite
2515 loops under rare conditions.
2517 Revised character set utilities (charneg.h) so that encoding
2518 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2520 For PQF, directive @term <type> sets term type for Scan/Search.
2521 Here <type> is general, string, numeric, null. The term type
2522 is inherited - just like @attr.
2524 New call odr_set_charset that sets character set conversion for
2525 international-strings on a ODR stream. Prototype is:
2526 int odr_set_charset(ODR o, const char *to, const char *from);
2527 The InternationalString is still represented as C string in YAZ
2528 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2529 won't). On the protocol level, you can use any encoding.
2531 Support for UNIX sockets in ZOOM.
2533 Solaris recv sometimes returns errno == ENOENT. It is treated as
2534 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2536 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2537 both client and server. Code by Morten Bogeskov.
2539 --- 1.8.7 2002/05/22
2541 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2542 that they can be used directly from Visual Basic. You must recompile
2543 your windows APP if you're using ZOOM.
2545 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2546 Commands "lang" and "charset" sets language and character set respectively.
2547 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2548 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2550 Attributes from multiple CCL fields may be OR'ed rather than merged
2551 using directive "@field or". Fields are still merged by default -
2552 equivalent to "@field merge".
2554 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2557 Fixed bug in zget for parameter ExtendedServicesResponse.
2561 --- 1.8.6 2002/03/25
2563 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2565 Client displays USR.1:SearchResult-1 (hits per term).
2567 Additional Search Info for search in Generic Frontend Server.
2569 Fixed CCL parsing of "field=s".
2571 WIN32 installer - using the excellent NSIS software from nullsoft.
2573 Fixed CCL parsing of "field = - <number>".
2575 Added function yaz_marc_decode that decodes MARC for line mode
2576 display or XML (similar to that used by JZKit).
2578 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2579 Z39.50. But ISO/ILL was, however.
2581 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2582 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2584 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2585 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2587 --- 1.8.5 2002/02/03
2589 New YAZ client features: Command completion and new commands:
2590 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2591 Code provided by Jacob Poulsen.
2593 New call oid_trav, that visits all registered OIDs via callback.
2595 Function ZOOM_record_get now returns const char pointer rather than
2596 void pointer. It saves a lot of type casts.
2598 For YAZ client, command "auth" now allows you to set authentication
2599 in IdPass style. It is enabled when three tokens are given - order
2600 is user, group and password.
2602 Fix memory leaks in MARC record handling for ZOOM.
2604 New option for YAZ client, -k <kilobytes> that sets
2605 maximum record size. Similar to -k option for generic frontend
2606 server and yaz-ztest.
2608 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2610 Prefix query parser reports "fail" when bad attribute set is given.
2612 Fix in MARC decoder. Proximity logging. Fix for attribute set
2613 in scan handler for server. Patches by Shigeru Ishida.
2615 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2618 Configure option --with-openssl=<dir> now works when a directory is
2619 specified. Patch provided by Morten Bogeskov.
2621 New option for YAZ client, -u <auth>, that sets authentication.
2623 ZOOM fix: error information was sometimes "missing", since error
2624 was cleared/reset too when it shouldn't.
2626 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2628 --- 1.8.4 2002/01/04
2630 Scan for ZOOM API. New object ZOOM_scanset. New functions
2631 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2632 ZOOM_scanset_destroy.
2634 New ZOOM function, ZOOM_connection_last_event, that returns type
2635 of last event (such as "receive data", "send data", "apdu received",
2638 New ZOOM option, schema, that specifies schema for retrieval.
2640 New CCL feature. Qualifiers can be aliases for one or more
2641 other qualifiers (if more than one is given, OR is used).
2643 ZOOM uses named result sets if target supports it.
2645 Two new YAZ client commands: . (dot, which sources a script of YAZ
2646 client commands), and ! (to execute shell command.). Implemented
2649 Working on Debian packages.
2651 --- 1.8.3 2001/11/19
2653 YAZ client enables named result sets only if target supports it.
2655 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2657 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2658 with key="host" to get same result.
2660 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2661 Function Z3950_resultset_record(s) returns references to records
2662 "owned" by resultset. To become owner use Z3950_record_clone.
2664 Function z_ext_record handles Extended Services. Thanks to
2667 --- 1.8.2 2001/11/12
2669 CCL Parser fix: ignore token comma when dealing with and-lists.
2671 Documentation updates for COMSTACK.
2673 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2674 Changed prototype Z3950_records. For some functions, int parameters
2675 were changed to size_t.
2677 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2680 New MARC decode/display function, marc_display_exl, which properly rejects
2681 non-ISO2709 records. YAZ client uses it.
2683 --- 1.8.1 2001/10/29
2685 Fix bug: local attribute set wasn't set correctly in PQF strings.
2689 * Old Z39.50 codecs no longer supported.
2691 Added ZOOM C binding. See http://zoom.z3950.org/
2693 Renamed states for COMSTACKs to avoid confusion with events.
2695 Implemented cs_look and proper cs_rcvconnect.
2697 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2699 Configure detects POSIX threads on OpenBSD.
2701 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2702 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2704 When error is returned from present handler, non-surrogate diagnostic
2705 is returned in present response (and fetch handler is no longer called).
2707 * Minor adjustments to pquery parser (PQF). Token characters may be
2708 escaped by using backslash (C-style).
2710 PQF parser allows string attribute values to be specified. For @attr,
2711 non-numeric characters after the equal-sign are treated as strings
2712 (e.g. @attr 9=title).
2714 CCL trunction character may be defined (@truncation in file)
2716 * function zget_ExtendedServicesRequest sets waitAction to
2717 waitIfPossible (was wait).
2719 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2722 CCL operator names may be set in field definition files (CCL_bibset).
2723 See ccl/bib1 for an example.
2725 Fixes in ASN.1 compiler for C++ compatibility.
2727 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2728 and "op_or" to avoid conflict with C++.
2730 Fixed problem with GNU readline detection on Redhat 7.0.
2732 Added step-size for Scan backend handler.
2734 Fixed bug that made the frontend server crash when no attribute
2735 set was specified for scan.
2737 Front-end server automatically switches to original working directory
2738 when installed as an NT service. Previously -w had to be specified to
2741 Added extended attributes for retrieval module (data1), so that data1
2742 records carry d1_readXML/SGML attributes. d1_read also supports
2743 null-data rules ( <tag/>)
2745 On UNIX when POSIX threads are available, a separate library libyazthread
2746 is created. Programmers should link with that library and the yaz library
2747 when using threads. The reason for the split was that some applications
2748 on Linux, such as Apache, doesn't work well when using shared objects that
2751 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2752 (or any frontend server) in SSL mode by specifying ssl: followed by
2753 address. Only tested on UNIX.
2755 Added feature for CCL module. Virtual structure s=al or s=ol generates
2756 and-list and or-list respectively instead of phrase search.
2760 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2761 log_mask_str. This was done to avoid name conflicts with other libraries
2762 (such as other PHP extensions).
2764 Added raw OID member for preferred record syntax (request_format_raw)
2765 and returned record syntax (output_format_raw) for backend fetch method.
2767 Config file yaz-config now accepts options so that it returns specific
2768 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2770 Shared library support for UNIX using GNU libtool.
2772 * Modified backend interface. Request/Response struct's replaced by
2773 one read/write C struct. For example bend_fetchrequest and
2774 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2775 Every handler - even search has to be registered in bend_init
2776 handler. This means that the YAZ library no longer refers to
2777 external functions and it makes it possible to make the whole
2778 thing a single DLL/SO.
2780 Added Segment handler for backend server.
2782 Added Zmbol/Zebra administrative functions to YAZ client.
2784 Threaded frontend server on UNIX (when POSIX Threads are available).
2785 Starting the server with option -T enables multi-threading.
2789 Added configure option --enable-comp/disable-comp to control use
2790 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2791 located in sub directory asn.
2793 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2794 in ${exec_prefix}/bin along with the other programs yaz-client and
2797 GNU automake used to maintain makefiles.
2799 Added several OID's.
2801 Changed retrieval module so that we can load records with no abstract
2802 syntax defined. Tagpaths in these records are fully composed of string
2805 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2809 On UNIX, the generated makefile now supports a proper 'make install'.
2810 The prefix can be set via GNU configure to set the install location
2811 (default is /usr/local).
2813 * YAZ programs client and ztest were renamed to yaz-client and
2814 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2815 locations, such as /usr/bin,/usr/local/bin,etc.
2817 * YAZ Header files were moved from include to include/yaz. YAZ Header
2818 files are referred to as include <yaz/log.h> rather than <log.h>.
2819 The YAZ include path (-I ..) is therefore the same as before. Programmers
2820 should update their #include statements or use -Ipath/include/yaz
2821 instead. The main motivation for doing this change is that YAZ header files
2822 can be installed in "standard" locations /usr/include,/usr/local/include
2823 without introducing conflicts, since ALL YAZ header files are stored
2824 in subdirectory yaz (under /usr/include for example).
2826 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2827 rather than project/workspace files. We switched because project files
2828 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2831 Changed name of logging function, logf, to yaz_log, to prevent name
2832 clash with some math-log functions. The YAZ header log.h defines logf
2833 to yaz_log (#define) so there should be no incompatibilities by this
2836 Added bend_start/bend_stop handlers for server. These handler are
2837 called on start/stop of server. For windows they are called whenever
2838 a service is started/stopped.
2840 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2841 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2842 in util/yc.tcl. The auto-generated C code structures are, in a few
2843 cases, incompatible with the old decoders. There are differences in the
2844 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2845 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2846 The preprocessor variable ASN_COMPILED is defined when the compiled
2847 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2848 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2849 wish to use the old encoders/decoders you can specify --disable-yc
2852 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2853 version so that it supports both new - and old version of DB Update
2855 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2856 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2857 change. The name parameter can be set to 0 in which no name is specified
2858 for the construction. The macros odr_implicit and odr_explicit sets name
2859 parameter to zero for the construction involved. New macros
2860 odr_implicit_tag and odr_explicit_tag are similar to the others,
2861 except that a name parameter is added. For programmers' that don't use
2862 ODR they probably only need to change the call to z_APDU and z_External.
2864 Added access control facility by interfacing the TCP wrapper library.
2865 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2866 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2867 name of the daemon and enables the access control as specified in
2868 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2870 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2871 den Dool <H.M.vdnDool@kub.nl>.
2873 Added reference ID parameter to most functions in server API - refer
2874 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2876 Changed name of ccl library to libccl.a (was ccl.a).
2878 Fixed bug in decoder for Explain (Category TargetInfo).
2880 Added support for GNU readline in client. Thanks to Jacob Poulsen
2881 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2883 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2884 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2885 IMPLEMENTATION! This change was made to the development version before
2886 the ZIG decided to retract the amendment. If any users MUST be
2887 compatible with the original Update definition, PLEASE CONTACT US, and
2888 we will include a separate definition corresponding to the old Update
2889 ES. Note that because of the change to the ASN.1 of the
2890 TaskPackageRecordStructure we cannot define a single structure that
2891 will support both versions.
2893 * Added const modifier to buffer parameter for some ODR/BER encoding
2894 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2895 completeWAIS, odr_dumpBER.
2897 Fixed bug in client.c which caused a crash when a scanResponse didn't
2898 contain positionOfTerm.
2900 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2901 * will cause an error in a client if a non-YAZ target sends both a
2902 * list of Scan entries and non-surrogate diagnostics.
2904 Retrieval module enhancements. Tag sets may be typed in the reference
2905 to it. From the .abs-file the "tagset" directive takes a third optional
2906 integer type for the tag set referenced. From a .tag-file the "include"
2907 directive takes a third optional type as well. The old "type" directive
2908 in the tag set itself is still recognized but acts as the default type
2911 Backend interface change. Individual Scan terms returned from bend_scan
2912 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2913 in include/backend.h.
2915 Retrieval module enhancements. Multiple tag sets and attribute sets may
2916 be specified in abstract syntax specs. Revised the error/warning for
2917 logging messages reported by the retrieval module when reading the
2920 Object Identifier system (oid_..) changed. The API is backwards
2921 compatible but the oid-routines now allocates new OID's when needed.
2922 Raw OID's may be specified in oid_getvalbyname.
2924 YAZ now uses GNU configure to generate Makefile(s).
2926 * Minor changes in some of the member names of DeleteResultSetRequest and
2927 DeleteResultSetResponse. See include/proto.h.
2929 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2930 and added member 'languages' in TargetInfo (which was missing).
2932 Changed the way attribute sets are handled in the retrieval
2933 module. These are now cached, just like the abstract syntaxes
2936 Changed YAZ so that it links with compiled ASN.1.
2938 Added Explain-schema definitions and mapping routines. The following
2939 Explain categories have been implemented: AttributeDetails,
2940 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2942 Fixed minor bug in Windows version of Server Library.
2944 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2946 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2948 Added EXTERNAL: UNIverse Resource Report (non-standard).
2950 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2951 ENUMERATED and SET OF.
2953 * Added 'const' to some of the char pointer arguments for the
2954 functions, data1_read_node, data1_getelementbytagname,
2955 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2958 Fixed bug in data1_insert_taggeddata - the last_child member of
2959 parent wasn't initialised.
2961 * Changed data1_read_record and data1_read_node so that the supplied
2962 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2963 doesn't refer to any parts of the "SGML"-buffer.
2965 Fixed bug in server library (Windows version of statserv_remove).
2967 * Changed code so that it compiles as C++. The type definition
2968 of Odr_fun which is a member of Odr_arm was changed. The result is,
2969 that an explicit typecast is needed for the fun pointer when
2970 using Odr_arm - as in:
2971 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2973 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2975 Implemented the new structured date and time definition as approved
2976 by the ZIG. Added schemaId element to the specificTag in Espec-1
2977 (also approved at the last ZIG). Thanks to RVDM.
2979 Added some Object identifiers (RVDM).
2981 Changed the Update Extended Service (RVDM).
2983 Added command "refid" to client which specifies referenceId for
2984 the following requests.
2986 Implemented extended service handling for server. See ztest.c
2987 for an example as well as backend.h. New handlers are registerd
2988 in the Init handler.
2990 * Changed interface for sort in server.
2992 Added new members to statserv_options_block. It allows a server
2993 to read options from another source than just the command line. Thanks
2994 to Charles Woodfield.
2996 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2997 renamed to zboolean. Some C++ compilers complained about the name.
2999 Minor changes to gils.abs. Added index 's' (sort) on title
3000 and date/time-last-modified.
3002 --- 1.4pl2 1998/1/30
3004 Fixed bug in server library regarding inetd mode (-i). This bug
3005 was introduced by release 1.4.
3007 --- 1.4pl1 1998/1/29
3009 Added sort facility in client and backend server interface.
3011 Fixed problem with dependencies in Makefile(s).
3013 Fixed bugs for encoders/decoders of extended services and
3016 Implemented sub-tree feature for schemas. Sub-trees are
3017 referenced in *.abs-files. See explain.abs for an example
3018 of the use of this feature.
3020 Modified bib1.att; local attributes for ANY didn't include
3021 ANY itself (only affects use of the retrieval module).
3023 Fixed bug in plain SGML reader in function data1_read_node:
3024 tags with prefix "var" was incorrectly interpreted as variants.
3026 Added feature "sub-schemas" to enable references to - and definitions
3027 of - group of elements.
3029 * Removed member parent from type data1_element (in data1.h).
3031 Implemented function odr_nullval() that returns the value of
3034 * Removed member num_children from data1_node (in data1.h).
3036 Made NT service interface part of the server library. The
3037 function statserv_main uses the NT service when required and
3038 calls the statserv_start / statserv_close routines.
3040 Routine zget_SearchRequest and zget_PresentRequest fills
3041 resultSetName/Id member with "default" instead of "Default".
3043 Fixed memory leak in server. Request queue member wasn't freed.
3045 Fixed nmem_exit so that memory is freed.
3049 Revised the CCL parser utility to be thread safe.
3051 Added function, oid_ent_to_oid, to replace the function
3052 oid_getoidbyent, which is not thread safe.
3054 * Added nmem_init and nmem_exit to initialize and release
3055 NMEM resources. Function nmem_init should be called once in the
3056 initial thread before NMEM/ODR is used. statserv.c and client.c
3057 have been changed accordingly. The change was necessary to make
3058 NMEM thread safe. The NMEM memory pool is shared amongst threads
3059 in a process. Unix-based applications will still work fine without
3062 Added NT Services interface for the the Z39.50 (statserv) Server.
3063 Refer to the ztest.c source on the usage.
3065 Windows 95/NT port using MSVC5.0. Project files are included in the
3068 * Defined new 'global' handle for the retrieval (data1) system. The
3069 new handled, data1_handle, describes the state of the data1 system.
3070 This handle is passed as first argument to virtually all
3071 data1 related routines. The functions data1_create and data1_destroy
3072 creates and destroys a data1 handle respectively.
3074 Added ODR encode stream member to all backend request structures
3075 init, search, scan etc. This stream should be used to allocate all
3076 memory used for the response when thread safe operation is needed.
3078 Changed the comstack utility, cs_addstr, to be thread safe. The
3079 returned hostname string returned by the function is now part the
3082 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3083 function. The cs_straddr takes a COMSTACK handle as argument, so this
3084 function must be used after cs_create and before bind/connect.
3085 This function is thread safe.
3087 Moved test server to 'ztest' directory - generic server code still
3088 in 'server' directory.
3090 Made prefix query (pquery.c) utility thread safe.
3092 Added new function modifier YAZ_EXPORT to 'export' public DLL
3093 functions when using windows (see include/yconfig.h).
3095 Added definitions to the OID database (util/oid.c) (RVDM).
3097 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3099 Added call to ccl_rpn_delete in client program.
3101 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3102 release of RPN structure.
3104 Added support for C++, headers uses extern "C" for public definitions.
3105 With input from RVDM.
3107 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3108 Thanks to Ronald van der Meer (RVDM).
3110 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3112 Added support for private extensions to the OID database
3113 (oid_setprivateoids()). Thanks to RVDM.
3115 Added optional, physical ANY (key replication)
3117 Fixed null-reference problem in GRS-1 output filter.
3119 Proximity operator added to Prefix Query Format (PQF).
3121 In test client command "base" accepts multiple databases.
3123 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3127 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3129 Smallish bug-fixes in the new encoders/decoders (explain).
3131 Bug fixed in DeleteRequest.
3133 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3135 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3137 Added SOIF syntax (using private OID for now) to retrieval module and client.
3139 Added Update extended service.
3141 Added SearchResult-1 additional info structure.
3143 Added optional CCL (ISO8777) interpreter as separate module. Available
3146 --- 1.2 1996/6/10 (1st anniversary release)
3148 Added Summary record syntax. Lightly tested.
3150 Added OPAC record syntax. Untested.
3152 Added ResourceReport service encoders/decoders. Untested.
3154 Fixed bug in z_Unit - wrong tagging on unitSystem.
3156 Fixed bug in the DiagRecs decoder.
3158 Added options for max PDU size and session timeout to frontend-server.
3160 Added documentation of query-language parsers and other supporting utilities.
3162 [frontend-server] Added Attribute set to the bend_scanrequest API.
3164 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3165 surrogate diagnostics were generated.
3167 [retrieval] Allow multiple local values for attribute.
3169 [retrieval] Allow multiple attributes per element in .abs files. index type.
3171 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3173 --- 1.1pl2 1996/4/10
3175 Minor changes, mostly specific to Zebra's requirements (retrieval)
3179 Repaired bug in frontend server when running multiple listening
3180 endpoints in dynamic mode.
3182 z_External() now won't break if a known, ASN.1 value comes encapsulated
3183 in an octet-string. The value will pass through unmodified in an Odr_oct.
3185 Added a bit of code to the demo client to decode & display
3186 ASN.1-structured records represented in the octet-aligned branch of
3187 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3189 Added z_ext_getentbyref() to the ASN module. Doc updated.
3191 * Completed the SCAN definition in the ASN module. This may break SCAN
3192 code based on older YAZ-versions at compile-time. The fix is easy -
3195 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3196 under the SCAN definition. Remember to initialize this, server-people.
3198 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3199 that this does not extend to ODR and ASN.
3201 Comstack allows insertion of established socket (primarily for
3202 inetd-operation of servers). Doc updated.
3204 Front-end server can now start from the inetd in TCP mode. Doc
3207 --- 1.0pl4 1996/1/24
3211 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3212 the rank and record number.
3214 Adjustments to the frontend server.
3216 Fixed diagnostic BER dumper. It ignored the file argument.
3220 Various changes to retrieval module.
3222 Changed the union discriminators of the protocol files from enums to
3223 ints paired with #defines.
3225 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3228 *Changed operator in the RPN structure to 'roperator', again to avoid a
3231 Fixed problems in Explain decoders/encoders.
3233 --- 1.0pl2 1995/12/6
3235 Memory bug in log module fixed.
3237 --- 1.0pl1 1995/12/5
3239 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3241 Bug in Explain DatabaseInfo module fixed.
3243 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3247 The shift to v1.0 signals that we now consider the *core* functionality
3248 of YAZ reasonably stable (the core being more or less equivalent to
3249 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3250 tested (Explain not at all - though that will happen soonish).
3252 Minor changes to code to support Windows port.
3254 Various minor changes after we're getting to use GRS-1 & co. more.
3256 Added Espec-1 format.
3258 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3259 of the protocol and it cannot be selected when encoding (maps into 'string'
3260 when decoding). Needed to talk to some servers.
3262 Demo client can request simple element set names.
3264 Added Diagnostic Format encoders/decoders.
3266 Added simple Close handling to frontend server (no hooks for resource
3267 reporting yet), and demonstration client.
3269 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3271 --- 1.0b3 1995/08/24
3273 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3274 handled incorrectly when records were requested in the searchResponse. This
3275 will only affect you if you use the frontend-server.
3277 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3278 Test-client will ask for and print GRS1. Ztest will return dummy records
3281 Added Explain encoders/decoders to the service-level API. Untested.
3283 Added Extended Services: Item Order encoders and decoders to the Service-
3284 level API. Untested. We could use a recent copy of the pertinent bits
3285 of the ILL protocol to add those bits.
3287 Added diagnostic format 1 encoders/decoders to the service-level API.
3290 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3291 odr_cons.c, which causes a more correct output.
3293 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3294 was always set to 0 when no records were requested in the searchRequest.
3296 * Added better external-handling. This shouldn't harm old code that
3297 *encodes* externals. It can break code that looks for a
3298 'single-ASN1-type' representation, since those types that are known
3299 are now decoded immediately. Look at the SUTRS sample code in
3300 seshigh.c and client.c. Documentation updated.
3302 Handling of structured records in bend_fetchresponse. Length -1 marks
3303 structured record, type is deduced from format field.
3305 --- 1.0b2 1995/06/27
3306 Fairly quick maintenance release to add SUTRS support.
3308 Fixed handling of SUTRS records in the demonstration client.
3310 * Added format field to the bend_fetchrequest and bend_fetchresponce
3311 structures of the backend API (frontend server). When the record is
3312 returned, the value of the format field is mapped to an OID. The
3313 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3314 of the record. The special value VAL_NONE in the bend_request means
3315 that no specific format was requested by the client. Documentation
3316 updated accordingly. Test server (ztest) will return a fixed dummy
3317 SUTRS record if your client requests SUTRS.
3319 Documentation updated accordingly.
3321 You can now set external libraries and RANLIB support in the top-level
3325 First public release.
