1 ICU: New conversion element 'join' which joins tokens into one
2 with a custom character given by rule attribute.
6 New GFS search member: present_number. This is a hint to the
7 search handler how many records are going to be fetched immediately
8 following search. There's no guarantee that it's going to be the case,
9 since it depends on hit count (for Z39.50 piggyback) and whether errors
12 Make a few functions static (private). The functions getbyte_stream,
13 ungetbyte_stream and yaz_gets are now private. They were never declared
16 yaz-marcdump: exit(5) for serious decoding errors
18 ISO2709 decoding: be more picky WRT header
20 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
21 was only used as to indicate that next-result-set-position should be
23 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
24 Based on patch from Ashley Sanders.
26 Make some functions static/private in PQF parsing. Those functions were
27 never declared in a public header and so should not be in use by
28 applications based on YAZ.
32 ZOOM: special options to control APDU logging.
33 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
34 logging of APDUs until "saveAPDU" option is set again. If logging is
35 already enabled the effect is that current APDU buffer is cleared.
36 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
37 logging (default behavior on new connection).
38 The APDUs sent/received can be obtained by using
39 Using ZOOM_connection_option_get(c, "APDU") or
40 ZOOM_connection_option_getl(c, "APDU", &l).
42 GFS: relay implementation_version from backend
43 From 3.0.40 and later, implementation_version from backend was
44 not used in init response at all.
48 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
49 mode at all. Probably never did.
51 Make a new version of ztest.pem that, at least, is not expired.
55 Fix description of CCL directive 'case'.
57 More tight checking of form arguments (yaz_uri_to_array). Makes
58 YAZ better at rejecting big and/or bad POSTs.
60 SRU decoding does not report more than up to 10 invalid arguments.
62 rpn2cql: less quotes in generated terms. Semantics unchanged, but
63 it's prettier this way.
67 New utility yaz_decode_init_diag. Defined in proto.h.
69 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
70 given for unix local socket.
71 The COMSTACK string for doing so is:
74 unix:/myfile:tcp:localhost:9999/mybase
75 unix:/myfile:localhost:9999/mybase
76 unix:/myfile:http://fakehost/mybase
78 debian: Use dpkg-buildflags in build process.
82 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
83 global's SRU service uses a recordPosition scheme starting from zero.
84 First record's position should be one
85 according to the standard.
89 Allow more namespaces for SRU. This is to allow, for example, an
90 incorrect namespace returned from server
91 http://services.igi-global.com/sru .
93 Minor fixes for compilation on Windows.
97 daemon: log total number of bad signals from child on stop so that it
98 is more easy to spot problems with child worker processes.
100 retrieval: empty backend name attribute omits element set
101 from being used in retrieval.
103 --- 4.2.40 2012/10/04
105 Implement Solr sort strategy "solr", similar to sru11 sorting.
106 This will implement the correct parameters on Solr requst to do
109 --- 4.2.39 2012/09/28
111 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
114 MARC: Extra/missing indicator handled for MARCXML.
115 The indicator length is given in header and is the same for the
116 whole record. If attributes ind1, ind2 are missing, then content
117 character defaults to blank. Extra indicator attributes (beyond)
118 indicator length are treated as an error.
120 Reformat: delete trailing whitespace
122 --- 4.2.38 2012/09/17
124 MARC: fix non-ASCII characters for leader. This is to ensure we can
125 generate XML in UTF-8.
127 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
128 in one node with structure word.
130 --- 4.2.37 2012/09/04
132 yaz-json-parse: JSON output may be pretty printed by using option
135 Increase default value of max message for Z39.50 Init for GFS, ZOOM
136 and yaz-client. Old value was 1 MB. New value is 64 MB.
138 --- 4.2.36 2012/08/22
140 yaz-client: don't display bogus records from SRU servers. Some SRU servers
141 return more records than given by *maximumRecords*. Skipping those in
144 record_render: simplify buffer return handling and fix at least one bad
145 memory reference, that broke the test_embed_record sometimes.
147 Allow http://user:pass@host notation for yaz_url_exec.
149 zoomsh: allow shell command to be executed. Via the system(3) call.
151 yaz_poll: Allow num_fds == 0
153 yaz-client: fix bad encoding of "itemorder item". The itemorder
154 item <no> - command forgot to use length of encoded Item Request
155 package. Error present since YAZ 3.
157 yaz-ztest: fix bad usage of session handle. Bug was introduced when
158 result sets were saved (271a9c83).
160 SRU recordPacking: guess record packing in response rather than looking
161 at the recordPacking element which, OF COURSE, changed semantics in SRU
164 Decode SRU 2.0 responses. The official namespace for responses, according
165 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
166 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
167 nature.com's server, however, usee namespace
168 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
169 we are now using a glob-expr to match up the namespace. ZOOM C and
170 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
171 I can not find a single real example showing the "real" namespace in
172 the documentation from OASIS. The namespace for requests is different
173 from responses, but this is not added to YAZ yet, when we don't encode
176 --- 4.2.35 2012/06/26
178 zoom/record_render: add support for Base64 decoding fo MARC records
179 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
180 which will decode base64 + ISO2709 marc-8 encoded material from text node
183 --- 4.2.34 2012/06/07
185 Add missing definitions ZOOM_resultset_get_facet_field_by_index
186 and ZOOM_resultset_facets_names.
188 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
191 Change APDU dump printing to avoid long leading blanks. For levels 16
192 or larger the level is shown and the indentation is truncated but
193 recursed with modula 8. This makes it still reasonable easy to read
194 - even for nested BER dumps.
196 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
197 return 0 (incomplete package) in case where the BER package was
198 considered too nested (return value of -2).
200 dumpber: lines of level 15 are not indented further. Two spaces per
201 indentation; indentation 15 or more is indented to a fixed indentation
202 and augmented with a level=<no> indication.
204 zoomsh: increase max size of command+args
206 GFS: No limit in RPN buf size in CQL to RPN conversion.
208 --- 4.2.33 2012/05/09
210 New function for daemon utility, yaz_daemon_stop .
212 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
214 --- 4.2.32 2012/04/25
216 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
217 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
219 --- 4.2.31 2012/04/23
221 YAZ daemon utility relays SIGUSR1 to child process.
223 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
224 would result in en empty database list - which in turn would result in
225 encoding failure for search.
227 Fix reading beyond string in yaz_sort_spec.
229 --- 4.2.30 2012/04/11
231 Add two new SRU diagnostics:
232 236: Access to specified database denied
233 1015: Init/AC: Maximum number of simultaneous sessions for Userid
235 Document the very useful ZOOM-C option "apdulog".
237 CQL to RPN: term may be passed through verbatim. This is enabled with
238 truncation.cql . The assumption being that the term is already CQL.
240 --- 4.2.29 2012/03/20
242 record_conv: leader spec may be given for marc element.
243 The leader spec is given as attribute leaderspec for element marc.
244 For example to convert a MARC21 record from MARC-8 to UTF-8:
245 <marc inputformat="marc" outputformat="marc"
246 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
248 record_conv: allow user-XSLT params. For example:
249 <xslt stylesheet="MARC21slim2DC.xsl">
250 <param name="myparameter" value="myvalue"/>
251 <param name="otherparameter" value="othervalue"/>
254 record_conv: fix error handling for missing marc charsets.
256 CQL: fix extra terms in wrong order.
258 --- 4.2.28 2012/03/06
260 record_conv: modify new API for conversion types. The conversion types
261 may be passed in new functions yaz_record_conv_configure_t and
262 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
264 Avoid mixed statement/variable declare; fixes compilation with Visual
267 --- 4.2.27 2012/02/28
269 Add non-standard SRU diagnostic: 235: "Database does not exist".
270 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
271 Update SRU to Bib-1 diagnostic maps accordingly.
273 CCL: add two new diagnostics for unsupported masking. The new
274 diagnostics are: "Embedded truncation not supported" and
275 "Single charcacter mask not supported".
277 --- 4.2.26 2012/02/23
279 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
281 --- 4.2.25 2012/01/11
283 Build YAZ for Ubuntu Oneiric.
285 CCL: allow parantheses for proximity operands. For example CCL query
286 (a) % (b) is now allowed.
288 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
289 marked dead, rather then being destroyed. If not, the session memory is
290 being free'd before the search/scan handler is finished. Also destroy
291 'request' memory in request_release rather than in various places,
292 which resulted in leaks from time to time.
294 --- 4.2.24 2011/12/21
296 cql_sortby_to_sortkeys: honor sort prefix.
298 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
299 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
300 The rpn2cql family of functions now always returns quoted CQL terms.
302 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
304 --- 4.2.23 2011/12/15
306 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
307 sequence is treated as one. For example, &&a=b&&&c& is identical to
310 --- 4.2.22 2011/12/05
312 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
313 APDUs for a connection to a WRBUF.
315 --- 4.2.21 2011/11/23
317 Fix cql_sortby_to_sortkeys. Completely broken before.
319 Make CCL's @truncation work again.
321 --- 4.2.20 2011/11/09
323 New ZOOM connection setting: tproxy. It's like proxy, but does not
324 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
325 to set resolved address + port for a connection outside ZOOM itself.
327 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
329 --- 4.2.19 2011/11/07
331 Fix uninitialized variable in Solr spell support (could cause SEGV
332 for SRU response decoding).
334 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
335 back-end's addinfo through into the ZOOM response addinfo.
337 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
338 they are separated by a colon and a space rather than simply
341 --- 4.2.18 2011/10/28
343 Add support for Solr spell-checking/suggestions through ZOOM.
344 If a Solr target has been configured correctly for spelling-checking
345 and suggestions, these will now be returned on the ResultSet option
346 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
348 --- 4.2.17 2011/09/28
350 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
351 with a flag whether to substitute escape sequences or not.
353 --- 4.2.16 2011/09/22
355 Fix nmem_strsplit_escape to substitute escape char properly.
357 New option for zoomsh -e , which makes it abort on first error and
358 return process exit code to indicate success/failure.
360 YAZ options utility supports special option -- which makes all it treat
361 all following arguments as non-options.
363 --- 4.2.15 2011/09/16
365 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
366 searched if absolute filename is given.
368 Fix conv_xslt() error-reporting when stylesheet is not found.
369 (The value of fullpath is meaningless in this situation.)
371 --- 4.2.14 2011/09/07
373 Fix problem in CQL sort node creation: un-initialized memory.
375 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
376 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
377 CQL sortby depending on whether Type-1 or CQL is actually sent to the
380 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
381 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
383 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
384 will make it possible to use both single-character mask (#) and wildcard (?)
385 in CCL . Throw diagnostic for left truncation because that is not supported
388 --- 4.2.13 2011/09/01
390 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
391 cases using escapes (\-sequences) and masking.
393 PQF parse fix: A trailing backslash followed by end-of-string (\0)
394 would result in a read one byte beyond string.
396 rpn2ccl may use Z39.50 masking for terms (t=z).
398 ICU check fix. Don't include library -lCrun on Solaris, unless present.
400 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
401 not --cppflags (which seeems like an error in icu-config).
403 --- 4.2.12 2011/08/27 RPM package only
405 cql2ccl: fix conversion of terms: operator characters were not
408 --- 4.2.11 2011/08/25 RPM package only
410 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
411 CCL parser will map both # and ? to their regular expression
412 quivalents (. and .*).
414 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
415 of reserved CQL characters.
417 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
418 is, so that they are passed through.
420 --- 4.2.10 2011/08/24
422 ZOOM SRU mode: more aggressive re-connect.
424 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
425 made available as a utility function, declared in <yaz/logrpn.h>
427 rpn2cql_structure() supports proximity nodes (except that the Type-1
428 proximity node's "exclusion" binary is ignored, as there is no way to
429 express that in CQL). Fixes bug #4564.
433 Fix SEGV that could occur if set command of zoomsh was given without
434 value (2nd argument).
436 Fix SEGV that could occur if unsupported transport was given for
437 COMSTACK - say https (when SSL was unavailable).
439 Build yaz-url on Windows too.
443 New utility to get web content. Header is url.h. A command line tool
444 yaz-url is part of the distribution and packages.
446 Fixes for SSL COMSTACK (when gnutls is in use).
448 New functions yaz_base64{encode,decode}. Header is base64.h.
452 ZOOM C includes HTTP response buffer as additional info if it fails
453 to decode the SRU response.
455 Make wrbuf_json_puts available.
459 zoom: throw diagnostic for invalid value for option "sru". Before a
460 bad SRU request was sent.
462 Adding new utility wrbuf_vp_puts.
464 Add cclxmlconfig.obj to win/makefile. It was missing completely.
468 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
469 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
470 redirect was used at the same time.
472 MARC line mode decoding: be less picky about length given - first
473 5 digits of header that is.
475 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
477 Changes to decoding of SRU records: a record with recordPacking=xml is
478 modified with a new root element <yaz_record> if the recordData contains
479 multiple children elements. This is to make the record XML parseable
482 RPN to SOLR conversion: encode special characters.
484 Generic Frontend Server: fix uinitialized member, stepSize.
488 Fix a bug in SRU decoding of records.. The database records stored
489 had un-initialized memory, but it would only be seen with yaz_record_render
490 and type_spec="ext" .
492 Fix a bug in ccl_qual_dup introduced in 4.2.3.
496 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
500 Add new utilities to convert from CQL to CCL . These utilities have
501 prefix cql_to_ccl defined in cql.h.
503 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
504 lead to memory heap corruptions when ICU utilities were in use.
508 Make compilation work without Libxml2.
510 yaz-client: remove redundant blanks in display of searchResult-1 term
515 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
516 resulting CQL node (tree) in a new node CQL_NODE_SORT.
518 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
519 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
520 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
521 Note that the CQL sortby spec is only converted when the GFS is already
522 converting from CQL to RPN (cql2rpn element).
524 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
525 specify whether to collapse delimitors or not. The existing nmem_strsplit
526 do collapse (collapse parameter = 1).
528 Windows installer: For NSIS, set InstallDir depending on x86/x64.
530 Rename internal func yaz_use_attribute_create. While non-static, this
531 function is not declared in a public header.
535 Add -lCrun when linking with ICU on Solaris.
537 More quicks character set conversions for OPAC records.
541 fix problem with record_render: records were converted (character set
542 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
546 SRU: add methods for handling DADS SRU-proxy facets.
548 Separate OPAC record character set for ZOOM_record. yaz_record_render
549 allows a character set given as charset=from/opacfrom,to where 'from' is
550 the character set of a bibliographic record, 'opacfrom' is character set
551 of OPAC record and 'to' is the target character set.
555 yaz-client: show may XML format records. Command show followed by 'format'
556 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
559 src/stemmer.c: Avoid using unnamed union. It is not supported by some
562 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
565 Update yaz.spec to operate on both SLES11 / Centos 5.5.
567 RPM: Release includes 'indexdata' name. Use indexdata in release name so
568 this package can be distinguished from other vendors.
570 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
571 as determined by configure
573 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
575 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
576 returns no error and no record, the present request is considered
577 partial (only a subset of the records could be returned by backend), and
578 so it is appropriate to set Present Status to partial-4.
582 Move yaz-config man pages to section 1.
584 More documentation about SOLR.
586 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
587 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
588 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
589 peers on some Linux systems. However, in general that does not work
590 so YAZ can not rely on that to work. Debian changed behavior in this
591 respect from Debian lenny to Debian squeeze (still testing as of Oct
593 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
595 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
599 Fix yaz-config output: echo_source not set correctly by configure.
603 SOLR WebService support for yaz-client and ZOOM.
605 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
607 --- 4.0.12 2010/08/17
609 Z39.50 facet support. Facet specifications are passed for search in
610 other-information with ASN.1 as defined in facet.asn and OID
611 .10.1000.81.5 . Facets are expressed as an Attribute list as known
612 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
613 3 is limit (number of entries to get in response). yaz-ztest returns
614 dummy facets if a client asks for them.
616 --- 4.0.11 2010/07/09
618 CCL fixes: bug 2895 and bug 3539.
620 GR1-display: add comma in display - was removed by mistake in
623 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
625 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
627 --- 4.0.10 2010/06/18
629 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
630 result set from a connection. The result set will be on its own
631 thereafter; no operations on it will perform retrievals from a target.
632 Only cached copies are returned.
634 ZOOM C:fix case for HTTP servers responding with Connection:close.
635 Ensure that if there is a current task it is resumed (like fetching
636 more records in a result set) . Bug #3484.
638 PQF parser: use odr_atoi for Odr_int (not atoi)
640 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
641 values that contain any non-digits are treated as string attributes
642 (previously decoding only checked for leading character ([0-9]). PQF
643 encoding: attribute string values are not surrounded by double-quotes.
647 New utility for managing threads - thread_create.h.
649 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
650 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
651 but YAZ' implementation do.
653 Fixes for yaz_cond-functions on Windows 7.
655 DLL export more symbols.
657 zoomsh: show record do NOT render opac.
659 Remove *.la files from Debian and RPM packages.
663 Debian package libyaz-dev depends on libgnutls-dev again (was
664 removed in YAZ 4.0.6, but due to Libtool it is still needed
665 even though yaz-config do not list libgnutls libs).
667 ZOOM: Use only one WRBUF for returning string results for
668 ZOOM_resultset. Reduces memory usage for ZOOM in general.
670 ZOOM: ZOOM_connection do not use a shared pointer to
671 ZOOM_resultset after ZOOM_resultset is destructed by
672 user. Reverts to YAZ 4.0.4 behavior.
676 record-conv: fix problem with at least one XSL conversion -
677 due to probably incorrect usage of XML XSL documents.
681 Fix yaz-config for static mode and the use of SSL (gnutls).
685 Forward decl timeval struct in mutex.h and gettimeofday.h.
687 yaz-config: fix 'static' mode linking.
691 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
692 are wrappers for pthreads or Windows. For Windows these are put in
693 a separate DLL: yaz_cond4.
695 libyaz.la (whole source) is compiled with thread. If thread support
696 is enabled enabled, all source of YAZ is compiled with treading support.
697 This allows core utilities such as yaz_log to use thread facilities.
698 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
699 thread utilities. This commit moves mutex utilities (mutex.c) from
700 libyaz_server.la to libyaz.la.
702 yaz-json-parse displays leading text until error.
706 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
707 patch from Giannis Kosmas.
709 SRU: no longer URL encode SRU database. The URL for an SRU server is
710 a URL and such is alreeady encoded - at least when given with leading
711 http:// or https://. This reverts behavior to YAZ 3.0.50.
713 Support for new MARC XML notation TurboMARC which like MARCXML is a
714 complete representation of MARC/ISO2709.. This one, however, is more
715 compact and allows for faster processing with XSLT. TurboMARC can be
716 used in the marcdisp.h API, from the yaz-marcdump utility and from
719 yaz-ztest can be configured - via the database - to perform certain
720 delays when it performs operations search, present and single record
721 fetch. This allows testers to make yaz-ztest act as a real or even slow
722 Z39.50 server. Refer to the yaz-ztest man pages for details.
726 wrbuf_destroy allows NULL WRBUF passed to it.
728 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
730 Add ZOOM_connection_close.
732 No fixed size buffers for ZOOM shell - bug #3257.
734 tstodr: make it work on s390 platform.
736 New icu iterator-functions. The new icu_iter-functions makes it possible
737 to use ICU chains from many threads.
739 yaz-client: better syntax check for show command.
743 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
746 New simple local-file XML include facility which allows file glob-patterns.
747 Refer to yaz/xml_include.h.
749 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
752 ZOOM_record_get supports new parameter "format" which makes it format XML
755 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
756 JSONText in ECMA-262) is JSONValue, not JSONObject.
760 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
761 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
763 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
764 POSIX/Unix builds .so with major version 4.
766 Remove old LOG_-defines from log.h. They have been obsolete and
767 undefined by default for the last 5 years.
769 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
771 GFS: Remove socket (int *fd) from search_rr handler. The socket
772 descriptor ptr is a facility that allowed a search handler to supply
773 a socket which would serve as a callback - when search was complete.
774 This facility has now been in use for years.
776 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
777 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
778 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
779 returns 'const char *' rather than 'char *. The returned string is
780 read-only and should not be modified by applications. COMSTACK cs_close is
781 now a void function - it no longer returns int. No applications check for
782 the value and the implementations has always returned 0.
784 ZOOM: use size_t for scan hit counts and str size. Functions
785 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
786 occ (hit count) and len (string length) are now of type size_t pointer
787 rather than int pointer. This is to be able to represent large hit counts
788 and to also just to use the proper type for string length (strlen result).
790 New JSON parser. Refer to include/yaz/json.h .
792 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
793 Used to be int in some cases. Many wrbuf_-functions used to return an int
794 indicating some length.. These return values were never used. And so they
797 ODR: odr_malloc, odr_total now takes size_t for size.
799 clone_z_type: fix leak; occurred for encoding failures.
801 --- 3.0.52 2009/12/03
803 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
804 bug was introduced in 3.0.51.
806 --- 3.0.51 2009/12/02
808 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
810 tcpip comstack: fix leak for getaddrinfo.
812 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
813 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
814 Decoding of SRU "path" database is performed by private function
815 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
816 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
818 yaz-client: honor base command for SRU. Change when database setting
819 is applied for SRU and ensure it is kept when a connection is reset.
820 Change also the way errors are displayed or SRU (decoding of packages).
822 --- 3.0.50 2009/11/02
824 Add support for extra request / response data for SRU codecs and GFS.
825 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
826 for extra data response buffer and length. For the GFS, both request
827 and response data (XML) is carried in extra_args and extra_response_data
828 for the search handler. Patch by Ko van der Sloot.
830 ZOOM: For queries that cannot be converted to the specified rpnCharset,
831 ZOOM now returns a diagnostic on the client-side ('invalid query' /
832 10010). This fixes bug #2113.
834 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
835 cmdfile included a 'quit' command that would result in a memory violation.
837 --- 3.0.49 2009/10/01
839 Make a number of functions defined in xmlquery.c static. These have
840 never been declared in a public header file (yaz/xmlquery.h) and was
841 made public by mistake.
843 Improve speed of character conversions (iconv utilities). This makes
844 conversions from MARC-8 faster.
846 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
847 unless type desired is "raw". This will prevent type "xml" from
848 returning ISO2709 .. Which obviously can not be XML parsed.
850 Fix memory leak in ZOOM that would occur if option apdulog was used
851 on a re-used connection.
853 Frontend server logs HTTP requests.
855 Frontend server now sends Z39.50 close when it times out (sesssion has
856 been idle for too long). Versions 2.0.30 and earlier also sent close.
857 But due to a mistake this was disabled in all versions after that, i.e.
858 the server would just close the socket immediately.
860 yaz-client emits a better message when receiving an unrecognised
861 userInformationField.
863 Skip zero-length subfields when decoding ISO2709. This rare case happens
864 if a record has two FS characters in a sequence. Without this patch
865 there would be a reference beyond char array in using_code_len fragments
868 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
870 --- 3.0.48 2009/08/28
872 The show command offered by the zoomsh command now takes a 3d optional
873 parameter type which is what is passed to ZOOM_record. If the type
874 argument is omitted, "render" is used.
876 RPN to CQL conv may use USE string attributes (bug #2978).
878 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
880 --- 3.0.47 2009/07/08
882 Function yaz_xml2query allows a diagnostic element in the PQF XML
883 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
884 code and additional info respectively.
886 The BER BOOLEAN is now the integral type Odr_bool which still happens
887 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
888 typedef'd to Odr_int. This is still an integral 'int', but it may be
889 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
890 ASN-1 compiler as well as programs has been updated to use the new types.
892 --- 3.0.46 2009/06/08
894 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
895 only the bibliographic record was rendered. For type=opac, an OPAC
896 record is only returned if it is present.
898 iconv: small fix for encoding of advancegreek.
900 yaz-client: avoid double display of SRU/SRW records (bug #2798).
902 yaz-client: option auto_reconnect=on really reconnects.
904 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
906 server: avoid null ptr ref for for yaz_poll errors.
908 build: fix RPM build for RHEL 5.3.
910 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
912 --- 3.0.45 2009/03/31
914 Fixed bug #2709: TCP connect returns Invalid argument.
916 Fixed compilation for mingw.
918 Honor charset for raw records (ZOOM_record_get).
920 Fixed use of errno for threaded mode that was seen on Solaris 10.
922 Fixed argument passing with blanks in value for Windows Service.
924 Disable YAZ' own log rotate by default (no 1 GB limit).
925 The variable l_max_size which specifies the log file limit is set to 0
926 (DISABLED): This is due to the fact that YAZ is most often deployed using
927 logrotate. Also YAZ can not perform log rotate because of unsufficient
928 permissions (setuid).
930 --- 3.0.44 2009/02/17
932 List supported encodings in man page for yaz-iconv.
934 Fixed missing SSL libs for --libs output
936 Re-established OID record syntax application-xml. Nobody should use it
937 but we don't want to change soname because of this symbol being absent.
939 --- 3.0.42 2009/02/02
941 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
943 Added member named_result_sets for init handler struct for the GFS. This
944 allows a server to disable named result sets.
946 Removed OID record syntax application-xml.
948 Added support for rule-based transliterator for ICU wrapper of YAZ.
950 Fixed bug #1902: yaz-icu XML output.
952 Make YAZ checks Emacs friendly.
954 BITSTRING value shows value. Bug #2346.
956 ISO2709 decoding: skip control characters from indicator data.
958 Omit sort key by default in yaz-icu's output.
960 Allow combined single char options (again) for YAZ' options function.
962 Utility yaz-marcdump got option to display YAZ version (-V).
964 Allow YAZ to use ICU 3.4.
966 Added new ICU test case which illustrates removal of diacritics.
968 --- 3.0.41 2008/12/29
970 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
972 --- 3.0.40 2008/12/29
974 For configure, using option --without-xml2 also disables Libxslt/Libexslt
977 Fixed bug #2352: yaz-marcdump crashes for certain record.
979 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
981 Added support for Danmarc2 to UTF-8 conversion.
983 Added support for ISO5426 to UTF-8 conversion.
985 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
986 implementation version.
988 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
990 --- 3.0.38 2008/11/10
992 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
993 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
995 ZOOM C now interprets databaseName option for ZOOM connection as path
998 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1000 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1002 Dummy Libxml2 types no longer defined in headers of YAZ'.
1004 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1007 --- 3.0.36 2008/09/26
1009 Various ODR chapter fixes.
1011 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1013 Added missing source for Windows compilation, mutex.c.
1015 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1017 For SRU connections in ZOOM all records up to "count" are now fetched.
1019 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1020 in Windows due to bad error handling for Libxml2.
1022 Added facility for sending arbitrary records (ASN.1 any) using
1023 ZOOM C's Extended service update. Patch by Sam Reynolds.
1025 New options for ZOOM C's connection, logapdu which makes ZOOM log
1028 --- 3.0.34 2008/06/18
1030 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1032 --- 3.0.32 2008/06/12
1034 Fixed memory violation that could occur when decoding UTF-8. This bug
1035 was only present in 3.0.30 of YAZ.
1037 --- 3.0.30 2008/06/06
1039 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1040 GNU TLS is used by default (if found).
1042 yaz-ztest returns OPAC records if a client asks for OPAC.
1044 Improved speed of MARC-8 encoding.
1046 Added support for lossy and loss-less MARC-8 encoding.
1048 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1050 Added new Windows Service wrapper (sc).
1052 yaz-client's itemorder command may now send a file.
1054 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1056 Added new function yaz_log_xml_errors.
1058 Allow (but warn) unknown XML attributes in MARCXML parsing.
1060 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1062 The UTF-8 to MARC-8 conversion now uses a different set of characters
1063 for Greek symbols. Bug #2120.
1065 --- 3.0.26 2008/02/21
1067 Added yaz_daemon (daemon.h).
1069 Fixed bug #2068: pkg-config trouble
1071 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1073 --- 3.0.24 2008/01/28
1075 Document --with-xml2 option.
1077 Added OPAC XML XSD (etc/opacxml.xsd).
1079 Allow glob mask for name attribute in retrieval element for the
1080 generic frontend server's retrieval facility.
1082 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1083 except POLLIN/POLLOUT.
1085 Fixed error handling in cs_listen. Bug #2037.
1087 --- 3.0.22 2008/01/20
1089 Fixed version in yaz/yaz-version.h.
1091 Fixed bug #2027: Crash when closing connection.
1093 Changed configure so that ICU support is only enabled if only ICU
1094 and Libxml2 is available (because the ICU chain is XML based).
1096 --- 3.0.20 2008/01/15
1098 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1099 is built. Only this DLL depends on the ICU runtime.
1101 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1102 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1104 Changed license of CCL module to 'Revised BSD'. After consultation with
1105 remaining members of the original EUROPAGATE consortium, we are re-issuing
1106 the CCL module without a separate license. The software was developed by
1107 Index Data as part of a research project. The special license was included
1108 to help feed usage information back to the project consortium to support
1109 project evaluation. At this time, the project consortium has long-since
1110 disbanded, and the majority of the original principals have retired. At the
1111 same time, we have significantly modified the software during the following
1112 years, to the point where very practically no original code remains. To
1113 simplify re-use of the software, we have contacted those members of the
1114 consortium who could be reached, and agreed to re-issue the module as a
1115 proper part of the YAZ package.
1117 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1119 CQL closer to being version 1.2 compliant. CQL also allows free-form
1120 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1123 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1124 bug could make Extended services handling crash in the ZOOM layer. This
1125 bug was only present in YAZ 3.0.18.
1127 --- 3.0.18 2007/12/19
1129 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1132 yaz-marcdump reads and writes collection wrapped records.
1134 Handle OPAC for record conversion module.
1136 Fixes for ICU wrapper.
1138 Allow ICU libs to be controlled with --with-icu .
1140 --- 3.0.16 2007/11/12
1142 Added yaz_poll which is a wrapper for select/poll. When poll is available
1143 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1144 sockets to be in use.
1146 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1147 functionality through an XML based configuration (ICU chain). This system
1148 is useful for search facilities such as Pazpar2 and Zebra that needs to
1149 perform tokenization of indexed material. The ICU code in a separate
1150 library libyaz3_icu.a.
1152 Added HTTP tunnel facility for COMSTACK, bug #1752.
1153 This is a facility that allows a Web proxy, such as squid, to tunnel
1154 Z39.50 traffic. This facility is "transparent" to must applications
1155 using YAZ. It's enabled by using pseudo transport connect: followed by
1156 the proxy address, followed by command, then follwed by he regular
1157 "virtual" addresss. For example,
1158 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1160 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1162 --- 3.0.14 2007/09/21
1164 Fixed bad memory reference in ZOOM_record - cuased by member not being
1165 initialized. This was a problem only in YAZ 3.0.12.
1167 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1168 fields were not removed.
1170 Changed the way C code is generated from codetables.xml. Made a MARC-8
1171 conversion trie for each characterSet section rather than codeTable.
1172 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1173 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1175 --- 3.0.12 2007/09/12
1177 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1178 from ZOOM_record_error).
1180 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1182 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1184 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1186 Better SRW-to-Bib-1 diagnostic mapping.
1188 ZOOM C and yaz-client announces SRU version 1.2 by default.
1190 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1193 Fixed in yaz_sru_decode to allow other version than 1.1.
1195 --- 3.0.10 2007/08/22
1197 Added support for SRU scan for ZOOM.
1199 Added support for the use of the older versions or Extended Service
1200 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1201 set to the version , 1=first, 2=second, 3=third. The third version is
1202 what ZOOM C has used so far. And that, obviously, is the default.
1204 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1205 therefore in Zebra and in SimpleServer-based applications). The new
1206 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1207 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1208 which is passed into the back-end search callback function.
1210 Added support for HTTP Basic authentication in clients: the SRU/W
1211 codec encodes the username/password elements of the PDU structure
1212 appropriately, and these may be set using the "user" and "password"
1213 options in ZOOM-C applications (the same options that are used for
1214 Z39.50 authentication).
1216 --- 3.0.8 2007/06/25
1218 Fixed bug #1208: SSL appears to be broken in ZOOM.
1220 Fixed bug #1206: Libxml2 include path weirdness.
1222 Added oid_name_to_dotstring.
1224 Allow elementSetName to be specified for ZOOM C record update.
1226 Allow waitAction to be specified for ZOOM C based for Extended Services.
1228 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1229 syntax OID. Bug introduced in YAZ 3 series.
1231 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1233 --- 3.0.6 2007/06/06
1235 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1236 directory. yaz-client now reads commands from file given by option -f
1237 if specified; then tries to read .yazclientrc in current directory.
1238 Failing that, it reads .yazclientrc from user's home directory.
1240 Added support for correlationInfo Note and ID for Record Update via
1243 Added yaz-client command querycharset which specifies character set for
1244 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1245 (termListAndStartPoint).
1247 Charset ISO5428:1984 is an alias for ISO5428-1984.
1249 Implemented a way to perform scan in a result set using Z39.50. This
1250 is achieved by attaching the result set name in the characterInfo
1251 (type InternationalString) of OtherInformation in the Scan Request PDU.
1252 The result set is identified in the otherinformation by the new OID:
1253 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1254 This allows for scan in result set and faceted search . Zebra did some
1255 of this in the APT term using attribute type 8 and value being result
1256 set. Using the OtherInformation approach for this is cleaner and easier
1257 to work with in proxies and the like. This facility can be used in
1258 yaz-client using new command setscan which takes a result set as first
1259 argument, start position (APT) as second.
1261 Changed decoding of SRU XML packed records to deal with servers that
1262 have recordData with XML data with multiple root nodes. Also make
1263 comparison for recordPacking case insensitive. Again, one server
1264 returns "XML" where others return "xml".
1266 For SRU responses allow Content-Type application/xml as well as text/xml.
1268 --- 3.0.4 2007/05/21
1270 Fixed bug in character set conversion of BER strings. Bug introduced
1273 --- 3.0.2 2007/05/08
1275 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1277 For OID class, use oid_class consistently.
1279 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1282 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1283 character set for bibliographic information interchange". By Giannis Kosmas.
1285 Added documentation on new OID API.
1287 --- 3.0.0 2007/05/02
1289 Changes to generic frontend server interface: added new member
1290 'query_charset' for bend_initrequest structure. A backend init handler
1291 should set this member to its native character set for query terms.
1292 When defined, the frontend server logic will announce this character set
1293 to a client if the negotiationModel bit is set by the client. All server
1294 implementors are encouraged to specify this. If a backend server does not
1295 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1297 Added CCL utility to remove terms (stop words) from resulting RPN
1298 tree. This is handled by functions with prefix ccl_stop_words_ .
1300 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1301 terms in RPN queries.
1303 Clean-up the CCL API. Moved some internal structures from ccl.h to
1304 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1305 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1306 This is replaced by ccl_parser_find_str which takes a string instead.
1308 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1309 libyaz.la is the core of YAZ except the generic frontend server and
1310 does not depend on POSIX threads anymore. libyaz_server.la is the
1311 generic frontend server facilities and uses POSIX thread functionality
1312 if available. The libyaz.la no longer depends on POSIX threads because
1313 the number of global structures is limited. NMEM no longer re-uses blocks
1314 between threads ; it simply free's memory immediately but allocates in
1315 "large" chunks as usual. We don't expect any performance penalties
1316 because of this. The yaz_log system is still using a global log_level so
1317 caution must be taken when modifying it with yaz_log_init_.. +
1318 yaz_log_mask_str. This, however, should not cause any trouble because
1319 these functions are called during initialization of application code
1320 anyway. `yaz-config --libs server` returns libs for server applications;
1321 `yaz-config --libs` returns libs for non-server applications.
1323 New OID database - with public definitions in oid_db.h. Removed old OID
1324 database including the head oid.h and definitions such as enum oid_value
1325 and struct oident. The new OID database uses the same string names as
1326 before but the 'protocol' is gone. There are now only two representations
1327 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1328 converts from string to OID; functions with prefix yaz_oid_to_string
1329 converts the other way.
1331 Change to emit_term() in CQL-to-PQF query translation: when a term has
1332 the /regexp relation modifier, do not process it for leading and
1333 trailing "^" and "*", which have quite different meanings in regular
1336 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1337 write handlers no longer carries a 'last' parameter. This will make
1338 yaz_iconv flush "less" characters. A flush is performed by call to
1339 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1341 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1342 removed, because function yaz_query_to_wrbuf does the same.
1344 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1345 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1347 Deprecated MARC utility functions removed.
1349 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1352 Branch split: YAZ_2_1_55_branch
1354 --- 2.1.54 2007/03/16
1356 Fix to ZOOM-C so that transparent reconnection is properly handled on
1357 connections that are in asynchronous mode.
1359 Fixed compilation on OpenBSD 4.0.
1361 Large strings in GRS-1 records are now properly displayed in yaz-client.
1363 Added character conversion support for "advancegreek"; based on patch from
1366 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1367 sequence is met. Before the error was not set so it would be unknown.
1369 Adjust yaz-marcdump MARC reader so that it skips until record separator
1372 --- 2.1.52 2007/03/07
1374 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1375 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1376 fd_set structure used as a bitmask for the FDs to be selected on.
1378 Using ACX_PTHREAD macro to check for POSIX threads.
1380 Fixed have-vsnprintf check.
1382 --- 2.1.50 2007/02/23
1384 Fixes for configure on BSD. Bug #900.
1386 Added snprintf/vsnprintf wrappers for systems that don't have
1387 limits (heavens forbid).
1389 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1390 created before all previous tasks were completed and removed from the
1391 task queue, the new task could be removed by a mistake.
1393 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1395 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1397 Fixed bug #832: Problem with MARC/charset in yaz-client.
1399 Fixed bug #668: save command line history for yaz-client.
1401 Fixed bug #830: pkg-config support.
1403 --- 2.1.48 2007/01/23
1405 Extended ZOOM result set options with two options that may be read by
1406 a client: resultSetStatus and presentStatus with values as specified for
1408 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1410 Fixed bug #827: Using SSL fails on Debian etch.
1412 Fixed bug #826: Weird looking chars for set of MARC records.
1414 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1415 that is treated as an ItemOrder with itemRequest being an XML document
1416 external. The value of "doc" is the content.
1418 Extended the GFS search facility. New member of bend_search_rr
1419 'estimated_hit_count' signals that hits is known to be an estmate
1420 (higher or lower than real hit count). New member 'partial_resultset'
1421 signals that the search was partial (hit count is lower or equal than
1422 real hit count). For Z39.50, the information is stored in resultSetStatus
1423 member of SearchResponse APDU. For SRU, the information is signalled
1424 via SRU diagnostic 59: "Result set created with valid partial results
1427 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1429 --- 2.1.46 2007/01/13
1431 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1433 Added ZOOM_connection_peek_event.
1435 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1436 the following new functions:
1437 ZOOM_event_nonblock, ZOOM_connection_process,
1438 ZOOM_connection_get_{socket,mask,timeout},
1439 ZOOM_connection_fire_event_{timeout,socket}.
1440 The existing blocking event handler, ZOOM_event, is a wrapper for the
1441 + blocking ZOOM_event_sys_{poll,select}.
1443 Implemented function ccl_xml_config which parses XML version of CCL
1444 configuration (bug #798).
1446 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1448 Added timings utility (yaz/timing.h)
1450 --- 2.1.44 2007/01/03
1452 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1455 Fixed bug #779: Rotation of apdu.log fails.
1457 Fixed for character set conversions:
1458 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1459 Honor G1 set in MARC-8 decoding.
1461 --- 2.1.42 2006/12/17
1463 Fixed bug #775: char conversion does not handle Alternative UTF-8
1466 Implemented function yaz_marc_read_line which parses MARC line format
1467 records. There is a wealth of formats out there. So far, this function
1468 reads line records produced by yaz_marc_write_line.
1470 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1471 more generic and easier to remember(!) options: -i format and -o format
1472 which specifies input format and output format respectively - where
1473 format is one of "marc", "marcxml", "line", "marcxchange".
1475 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1476 does not print anything except warnings for records.
1478 For yaz-marcdump, added support for MARC split into files (-s) with a given
1481 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1482 spec, at http://www.loc.gov/standards/sru/record-update/
1483 This has changed the binary layout of the following structs:
1484 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1485 bend_update_rr . Patch by Ko van der Sloot.
1487 Added GFS utility function bend_assoc_is_alive which returns 1 if
1488 association is still alive (client is connected); 0 otherwise (client
1489 closed connection). This allows busy servers to stop working for
1492 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1493 been a separate piece of software. This version of ziffy has been modified
1494 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1496 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1498 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1499 Client code may now interrogate options such as "init_opt_sort" to
1500 find out whether the server claims to support various options.
1502 --- 2.1.40 2006/11/27
1504 Added utilities yaz_{set,get}_esn to set/get element set name from
1507 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1508 of YAZ and has been so since YAZ 2.1.10.
1510 Implemented ZOOM_record_error which returns error information for
1511 record (surrogate diagnostic).
1513 --- 2.1.38 2006/10/31
1515 Updates for SRU Update by Ko van der Sloot:
1516 1. Changed name from "operation" to "action"
1517 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1518 versions in the code, marked as 'backward compatible'.
1519 3. Added diagnostics for SRU Update.
1521 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1523 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1525 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1527 For GFS, fixed problem with SRU diagnostic 'First record position out of
1528 range' being issued for 0 hits.
1530 zoomtst10 part of Windows Build.
1532 --- 2.1.36 2006/10/13
1534 Implemented yaz_filepath_comp which splits a path into file path
1535 components (required by Zebra 2.0.3+).
1537 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1538 BSD inspired license until now so this should not have any real impact on
1539 anybody. See http://www.opensource.org/licenses/bsd-license.php
1541 Fixed bug #687: Missing log lines.
1543 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1546 Fixed bug #689: SRU diagnostics to be added.
1548 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1549 whether a connection is idle (no more work do do).
1551 --- 2.1.34 2006/10/04
1553 Change type of optval from long to int for invocation of setsockopt with
1554 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1556 Added support for specifying the max log file size for the Generic
1557 Frontend Server. The size is given with option -r.
1559 --- 2.1.32 2006/09/21
1561 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1563 --- 2.1.30 2006/09/17
1565 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1568 Fixed bug in Generic Frontend Server that could cause a server to stop
1569 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1571 For the generic frontend server, the maximum record size is used as maximum
1572 size of incoming packages (SRU + Z39.50). The value until was previously
1573 only used in Z39.50 Init negotiation and, later, in a session controlled
1574 sizes of records returned. This is controlled using -k option. It can be
1575 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1577 --- 2.1.28 2006/09/04
1579 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1582 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1584 New option for yaz-marcdump -lpos=value which allows setting a portion
1585 of MARC header to a certain value.
1587 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1589 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1590 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1592 --- 2.1.26 2006/08/15
1594 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1597 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1599 --- 2.1.24 2006/08/08
1601 Fixed MARC ISO2709 encoding routines to deal with character set
1604 Minor changes to GFS logging. Database included in search request log
1607 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1608 cached/multiple records.
1610 Shared libraries are built by default on Unix+configure.
1612 Changed cql2pqf transformation to use a different evaluation order. The
1613 new order is: always, relation, structure, position, truncation, index
1614 and relationModifier. Old order was: always, relation, relationModifier,
1615 structure, index, position, truncation. Note that the the latter ones
1616 override former ones for identical attributes.. The new scheme means that
1617 it is possible to override any existing attribute with a relationModifier.
1618 And also that it is possible to override everything for the index rule
1619 (except the ones listed in relationModifier). No order is perfect but this
1620 one, we believe, covers more real cases.. The "always" should have been
1621 called "default", since the attributes there can be overridden with all
1624 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1625 compilation phase, but also for yaz-config --cflags output. This allows
1626 us to have public headers with Libxml2 stuff in them . It should also,
1627 eventually, make Libxml2 checks redundant in packages using YAZ, such
1630 --- 2.1.22 2006/06/15
1632 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1633 stored in uri, message and details.. Previously diagnostics were stored
1634 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1635 compatibility.. but he's probably the only one affected, so.
1637 Added support for CCL, compiled on the client side, in ZOOM-C. This
1638 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1639 input; the resulting query objects can be used for for searching with
1640 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1642 YAZ' configure searches for OpenSSL by default.
1644 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1645 SL_CTX_use_certificate_file. See
1646 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1647 for more info. Thanks to Ko van der Sloot.
1649 --- 2.1.20 2006/06/02
1651 Bug #600: SRU GET, POST support for yaz-client. Introduced
1652 command 'sru' which selects method SOAP/GET/POST.
1654 Allow missingValueAction to be specified for the sortspec string -
1655 function yaz_sort_spec. By default, the missing value action is null.
1656 Use ! to specify "abort". Use = followed by stringvalue to specify default
1659 Ensured that Present-handler (if defined) is called in GFS before any call to
1660 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1661 searchRetrieve requests.
1663 Documentation for YAZ is now based on the Docbook XML/XSLT using
1664 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1665 is no longer depending on jade/openjade or docbook-to-man scripts.
1666 PDF is no longer part of the distribution - but can optionally be
1667 made using DSSSL/jadetex or FOP.
1669 Added retrieval handling support in Generic Frontend Server to support
1670 conversion between MARC/XML as well as XSLTtransforms. See
1671 etc/yazgfs.xml for an example.
1673 Added Authentication support to Generic Frontend Server in SRU
1674 mode. Authentication using HTTP Basic is supported, as is the use
1675 of 'x-username' and 'x-password' parameters in the request itself.
1677 Added support for a new character set MARC8s identical to MARC8 except
1678 that it converts combined characters to single Unicode characters in the
1679 Latin-1 range (when possible).
1681 --- 2.1.18 2006/04/24
1683 ASN.1 compiler 0.4: generates brief Doxygen file header for
1684 generated .h/.c files.
1686 Utility yaz_iconv now supports conversion to MARC-8.
1688 New facilities for the MARC module. The reading - and writing of
1689 content are separate methods for the yaz_marc_t handle. The following
1690 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1691 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1692 format). Write functions have prefix yaz_marc_write_.. The existing
1693 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1694 available. Removed support for OAI-MARC and simplexml (not the
1695 simplexml from PHP5).
1697 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1698 to be returned for this connection.
1700 --- 2.1.16 2006/03/31
1702 Allow multiple languages and charsets to be specified with
1703 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1704 negcharset iso-8859-1,utf-8
1706 Translation of proximity nodes from CQL into PQF now works.
1708 Moved to automake 1.8, 1.9.
1710 Added function yaz_log_set_handler which allows a log handler to be
1711 installed. This handler will be called for all log messages. Output
1712 to file is also produced; but that can be disabled by passing NULL
1713 fname to yaz_log_init_file.
1715 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1717 For SRW (including GFS), accept application/soap+xml as content-type
1720 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1721 produces NO stylesheet reference even if a default stylesheet is specified
1724 --- 2.1.14 2006/03/14
1726 Updated Windows package to include yazd.dll + yazd.lib for the
1727 Development component.
1729 If the environment variable YAZ_LOG is set, then it is used as a
1730 string indicating the default level of logging to use if not
1731 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1732 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1733 used as before. So, for example, to omit warnings from YAZ logging,
1734 export YAZ_LOG=-warn
1736 cql_transform() now map structure and other attributes before indexes,
1737 so that index-specific structures and other attributes can override
1738 defaults. So now a combination of mapping specifications such as:
1740 index.dc.date = 1=date-modified 4=5
1741 does the right thing.
1743 cql_transform() now also respects the "always" mapping specification,
1744 which establishes an initial set of attributes to be used for all
1745 terms except where overridden by more specific attributes associated
1746 with the index, relation or modifier.
1748 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1749 which mode to use; one of "post", "get" or "soap" (SRW, default).
1751 Fixes for yaz_iconv routines: changed trie-based character set conversions
1752 to use only non-negative values for bit fields due to Sun's C compiler not
1753 supporting negative values.
1755 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1756 sequences where not read correctly. Fix by Rustam Usmanov.
1758 Updated win/makefile to use options, settings which makes things
1759 compile with VS C 2005.
1761 --- 2.1.12 2006/02/01
1763 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1765 In ZOOM socket code, use select instead of poll on MacOSX.
1767 ZOOM-C now support client-side compilation of CQL into RPN that is
1768 sent to the server, enabling CQL to be used against all Z39.50
1769 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1770 ZOOM_query object, and submit it using ZOOM_connection_search().
1771 The CQL-to-RPN translation uses a configuration file, the name of
1772 which must be specified in the Connection's "cqlfile" option.
1774 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1775 function, which takes as its start-term parameter a ZOOM_query object
1776 (which may have had either CQL or RPN set into it).
1779 --- 2.1.10 2005/11/29
1781 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1782 GFS to support this as well. Backend handler, bend_srw_update, does the
1783 update work. Code contributed by Ko van der Sloot.
1785 Allow retrieval of Search Result-1 information in ZOOM by the use of
1786 options that are attached to a result set. ZOOM documentation updated
1789 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1790 UTF-8 conversion. Patch by Raj Patel.
1792 Added option -m to GFS to control formatting of timestamps in log file.
1794 Added 'exit' as synonym for 'quit' in yaz-client
1796 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1797 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1798 for the new members. Patch by Ko van der Sloot.
1800 Added support for SRU POST. It is supported for content-type
1801 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1803 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1804 Instead make the library libyaz.la multi-threaded. Threading as a whole
1805 can still be disabled by configure option --disable-threads. Previosly,
1806 with older GLIBCs there were problems with MT libs under Apache. This
1807 has now been fixed a long time ago.
1809 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1812 CQL module modified to be case insensitive for relations/indexes/operations.
1814 Fixed bug in CQL transform code: incorrect value relationModifieder
1817 Added 'show all' command for yaz-client which retrieves all results
1820 Added new yaz-client, xmles, which takes a (private) OID and
1821 a document to be sent as an extended service request.
1823 Describe new yaz-client commands wait_response and set_auto_wait.
1825 Increase TCP/IP listener backlog from 3 (which I am guessing was
1826 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1827 that the socket will queue as many incoming connections as it's able
1828 to handle ongoing connections. In other words, it will never now
1829 refuse a connection that it would be able to handle merely because
1830 it's not got around to accepting() enough of the pending connections
1831 yet. This is the behaviour anyway under Linux, where the listen()
1832 argument is ignored; but not under BSD and on systems such as
1833 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1834 YAZ-based servers should now be uniform across operating systems in
1837 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1838 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1839 This allows yaz-marcdump to read large MARC batches (>2 GB).
1841 Modified all YAZ source files - except the source which is auto-generated
1842 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1845 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1846 corresponding to the existing *_setl() function. These allow option
1847 values containing arbitrary valuues.
1849 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1850 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1851 except that it returns an indicator of whether or not the sort
1852 criterion was accepted (0 for OK, -1 for invalid).
1854 --- 2.1.8 2005/06/07
1856 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1857 MARC output rather than returning "new" buffer.
1859 yaz-client warns about unknown init options.
1861 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1863 --- 2.1.6 2005/05/24
1865 Added support for SRW sort in Generic Frontend Server. Patch
1866 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1867 sortKeys - or NULL if none is provided.
1869 Fixed bug #307: It was impossible to specify indefinite/no timeout
1870 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1873 Added support for multiple languages and charsets to be specified in
1874 ZOOM. Each charset/language is separated by a blank. If negotiation is
1875 in effect in init-response, Option
1876 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1877 Code based on patch by Vasiliy Osadchuk.
1879 Fixed bug #306: infinite recursion that occurred when calling
1880 yaz_log_level_init as the first call (before other log level or
1883 Fixed bug in scan handling in front end server: if preferred-Position-In-
1884 Response was non-present, a NULL pointer referece was performed.
1886 --- 2.1.4 2005/04/26
1888 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1889 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1890 now defined for all those error codes. So instead of putting 109 in
1891 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1892 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1894 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1897 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1899 Program yaz-client now exits and produces an error message if multiple
1900 Z39.50 servers are specified on the command line (none or one allowed
1903 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1906 --- 2.1.2 2005/03/16
1908 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1910 Fixed bug #272: Preserve spacing for CCL terms.
1912 --- 2.1.0 2005/03/14
1914 Added support for virtual hosts and multiple backend servers for
1915 the YAZ frontend server. The configution is XML based and
1916 support specificition of CQL to RPN mappings and explain information.
1917 See section "Virtual Hosts" in the YAZ manual.
1919 Extended OPAC display utility. OPAC display utility renders
1920 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1921 to supplement yaz_marc_decode_wrbuf.
1923 Fixed a bug in MARC decoder that could caused it to crash for some
1924 invalid MARC records. More diagnostics and warnings where added in
1925 XML output (warnings, etc are stored in comments).
1927 --- 2.0.34 2005/02/08
1929 Fixes for UNIX domain sockets. Bug #261.
1931 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1933 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1934 Added yaz_marc_subfield_str which defines subfield lead string which is
1935 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1936 yaz_marc_endline_str which defines end of fields string used in
1937 YAZ_MARC_LINE format. Default string is newline.
1939 Experimental support for MarcXChange. This format can be produced
1940 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1941 http://www.bs.dk/standards/MarcXchange.xsd
1943 Added yaz-client commands scansize that sets maximum number of
1944 entries to be returned by scan.
1946 --- 2.0.32 2005/01/11
1948 Added support for SRW scan in yaz-client and Generic Frontend Server.
1950 * Added whereInList member to SRW Scan Term.
1952 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1954 Fixed NMEM system to return aligned blocks on the smallest boundaries
1955 that are suitably aligned for all possible types on the particular
1956 architecture YAZ is being built for.
1958 --- 2.0.30 2005/01/04
1960 Fixed numerious warnings that was issued with newer versions of GCC.
1962 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1963 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1966 Make YAZ Generic Frontend Server slightly faster.
1968 Enhance (and reduce) logging for Generic Frontend Server.
1970 Revert YAZ log system so that it flushes every write operation
1971 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1973 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1974 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1975 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1976 will effectively disable old definitions.
1978 --- 2.0.28 2004/11/09
1980 Added yaz_log_time_format which specifies log format using
1983 Added yaz_log_module_level which returns mask for a module. Value
1984 is non-zero mask a if module is enabled; zero if disabled.
1986 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1987 in include/yaz/cql.h.
1989 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1991 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1993 Fixed bug #172: RPM builds does not enable SSL.
1995 Doxyfile.in part of dist. Doxyfile generated by configure.
1997 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1998 are given and the corresponding component does not exist.
2000 Extend CCL documentation in YAZ reference. Describe r=r.
2002 --- 2.0.26 2004/10/01
2004 Fixed MARC->MARCXML conversion to properly deal with
2005 fields, subfields, indicators having non-ASCII characters.
2007 Fixed MARC->MARCXML conversion so that ASCII control characters
2008 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2011 Added YAZ GFS support for conversion from Z39.50 surrogate
2012 diagnostics to SRW surrogate diagnostics.
2014 Bug fix: YAZ GFS did not return schema in explainResponse.
2016 --- 2.0.25 2004/09/30
2018 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2019 now converts recordSchema to elementSetName as well as schema URI.
2021 Fixed bug in COMSTACK that prevented HTTP request packages from being
2024 --- 2.0.24 2004/09/29
2026 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2027 does not require white-space before and after the dash in a range, e.g.
2028 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2031 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2032 due to new GCC removing "redundant" code.
2034 Added yaz-client commands scanpos and scanstep that sets preferred
2035 position and step-size for scan.
2037 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2039 Added CCL utility ccl_qual_buf which parses one or more CCL
2040 spec lines in a buffer.
2042 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2043 of name and value - ignoring empty lines and comments.
2045 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2047 Added odr_get_element_path which returns current element path for an
2048 ODR handle. This utility is useful in error handling or user-defined
2051 Added ODR_PRINT utility odr_set_stream which is is a more generic
2052 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2053 to a write function and pointer to close function. The close function - if
2054 non-NULL - will be called during odr_destroy.
2056 Fixed bug in CCL parser where truncation char was not removed from
2057 right side when truncation=both was in effect.
2059 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2062 --- 2.0.23 2004/08/11
2064 Fix buffer overrun in CQL parser when dealing with proximity (%).
2066 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2067 to UTF-8/UCS conversion is now only based on codetables.xml.
2069 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2071 --- 2.0.22 2004/08/06
2073 Add support for more "commit changes" in ZOOM (uses Extended Services).
2075 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2078 Yet another small fix for configure of SSL.
2080 --- 2.0.21 2004/05/14
2082 Fix SSL libs for configure when --with-openssl=DIR is given.
2084 --- 2.0.20 2004/05/10
2086 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2088 SSL comstack now uses yaz.pem certificate file on server side
2089 by default. Certificate filename can be configured by calling
2090 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2092 Fix bug regarding multiple calls to ZOOM_connection_connect.
2094 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2096 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2097 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2099 ZOOM now allows inspection of X509 peer certificate for verification.
2100 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2102 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2103 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2104 as "modular" but it simplifies things.
2106 Added cs_get_peer_certificate to that returns peer X509 PEM.
2108 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2109 NULL if SSL is unavailable.
2111 Documentation about MARC decoding tools.
2113 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2115 --- 2.0.19 2004/03/30
2117 Rename CHANGELOG to NEWS to follow GNU style packing.
2119 Fix bug with missing initialization of member in init_diagnostics.
2120 This bug affects threaded version of GFS server.
2122 --- 2.0.18 2004/03/20
2124 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2127 Ensure zlib.dll is packed with Windows install.
2129 --- 2.0.17 2004/03/17
2131 Fix encoding of xsd:string to use text instead of CDATA.
2133 Fix endless loop in CQL parser with unbalanced ".
2135 Use a more compact way to store MARC-8 conversion tables.
2137 --- 2.0.16 2004/03/16 Debian only
2139 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2142 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2147 --- 2.0.15 2004/03/01
2149 Another fix for decoding of XML packed records.
2151 --- 2.0.14 2004/02/25
2153 Fixes for Chunked encoding. White space not ignored after length spec.
2155 Update NS and use default NS for SRW diagnostic elements.
2157 --- 2.0.13 2004/02/23
2159 Implement ZOOM_resultset_cache_reset which resets record cache.
2161 Implement ZOOM_resultset_sort which sorts a result set.
2163 Implement chunked HTTP transfer.
2165 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2167 --- 2.0.12 2004/02/16
2169 Added member 'schema' to bend_explain_rr structure so that backend
2170 can specify explain record identifier. Defaults to Zeerex 2.0.
2172 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2174 --- 2.0.11 2004/02/16
2176 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2179 Added init command for yaz-client which sends "extra" init request.
2181 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2182 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2184 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2186 Make ZOOM error code for "invalid query".
2188 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2190 --- 2.0.10 2004/02/05
2192 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2195 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2197 Added option -p <file> to make Generic Frontend Server to write PID file.
2199 Added option -D to put Generic Frontend Server in background on its own.
2201 Make ZOOM C recognize option "password". If unset, "pass" is used
2202 (for backwards compatibility).
2204 Fixed a bug in Generic Frontend Server that could make it crash if a
2205 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2208 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2209 Must be issued before open, in order to be in effect.
2211 --- 2.0.9-6 2004/01/12 Debian/Windows
2213 Make the SRU server more picky WRT unknown params, etc.
2215 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2217 New YAZ client command, options, that sets Z39.50 options.
2219 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2220 options from a string of tokens (one token for each option bit).
2222 Update SRW diagnostic code messages.
2224 --- 2.0.9-5 2004/01/07 Debian/Windows
2226 Handle user defined stylesheet for SRW/SRU.
2228 --- 2.0.9-4 2004/01/06 Debian/Windows
2230 Fix bug in decoding of Content-Length.
2232 --- 2.0.9-3 2004/01/06 Debian/Windows
2234 Fix a bug with decoding of XML packed records.
2236 --- 2.0.9-2 2004/01/05 Debian only
2238 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2240 Fix bug in SRW/SRU diagnostics decoding.
2242 --- 2.0.9 2004/01/05
2244 Fixed bug in Generic Frontend Server which could drop records exceeding
2245 preferred message size. Reported and fixed by Irina Dijour.
2247 Fixed calculation of package size for structured records in Generic
2248 Frontend Server. Reported and fixed by Irina Dijour.
2250 Fixed namespace for SRW/SRU diagnostics.
2252 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2254 --- 2.0.8 2003/12/22
2256 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2257 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2260 CQL changes to reflect recent changes to the specification:
2261 * Documentation talks about context sets instead of index sets.
2262 * Documentation talks about indexes instead of qualifiers.
2263 * The CQL-to-PQF transformer's configuration file now uses
2264 "index.set.name = <attributes>" instead of the old form
2265 "qualifier.set.name = <attributes>". (Both forms are still
2266 understood but the latter is deprecated.)
2267 * CQL terms with no explicit index specified are now interpreted as
2268 cql.serverChoice instead of srw.serverChoice (which of course
2269 behaves exactly the same.)
2271 --- 2.0.7 2003/12/16
2273 MARC conversion can now generate ISO2709 output in another
2274 character set. yaz-marcdump uses this facility if you invoke it
2277 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2278 functions from there can be used from C++.
2280 --- 2.0.6 2003/12/04
2282 Frontend server now transfers memory from decoded packages to stream
2285 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2286 references to show up.
2288 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2289 the ZOOM Abstract API. The older names for the same options are still
2290 also supported for the benefit of old applications.
2292 ZOOM-C supports "implementationId" and "implementationVersion" options
2293 to go along with "implementationName". These allow the user code to
2294 specify identification strings to be sent to servers.
2295 Add OID for the new ExtLite attribute set.
2297 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2298 as requested/supplid by Ere Maijala <ere@atp.fi>
2300 For generic frontend server, reverse the order of
2301 "toolkit-supplied / application-supplied" strings sent as implementationId,
2302 Name and Version. Also, remove the spaces around the slash. This brings
2303 the GFS in line with the behaviour of ZOOM-C on the client side.
2305 Add function ZOOM_scanset_display_term.
2307 yaz-client shows scan displayTerm if present.
2309 Utility yaz-iconv is now installed by default along with the man page
2312 Extend configure check for OpenSSL to use pkg-config where available (such
2315 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2316 server to specify uid/gid/mask for socket using the format
2317 unix:[user=uid,][group=gid,][umask=mask,]file=path
2318 If file= is omitted the existing format is assumed, e.g.
2320 in which case the mask is 0666 (rw for everybody).
2322 Major restructure of YAZ source. All source in libyaz is in src directory.
2323 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2324 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2326 Added man page for utility yaz-marcdump (used to be called marcdump).
2327 yaz-marcdump is installed by 'make install'.
2329 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2330 of incoming package failed.
2332 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2334 Change prototype of odr_perror: add const to message string.
2336 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2338 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2339 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2340 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2341 DNS lookup. There should not be any compatibility problems with this
2342 assuming that blocking=1 or 0 is used.
2344 Fix bad reference in UNIX comstack in function cs_addrstr.
2346 Fix for compilation on AIX.
2348 The generic front-end server (server/seshigh.c) now supports returning
2349 Init diagnostics to the client in User-information-field, in
2350 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2353 --- 2.0.4 2003/09/04
2355 Allow any CQL relation (not just all,any,exact,scr).
2357 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2358 that features the same UI.
2360 Implemented command update0 in YAZ client which is equivalent to
2361 update but uses old of Ext Update ASN.1.
2363 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2364 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2365 Previously no OID was used for this info.
2367 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2368 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2369 returns 'malformed search term' otherwise.
2371 SortResponse member resultCount now set to NULL in sort handler of
2374 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2377 Add three new utility functions for translating OIDs between various
2378 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2379 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2380 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2381 char *oid_to_dotstring(const int *oid, char *oidbuf);
2382 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2384 Reverted modifications for ES Update definition for z_IU0Update
2385 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2386 is back to YAZ 2.0.2.
2388 String value attributes for CCL parser.
2390 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2391 which their FirstSearch server returns in Init responses, sometimes
2392 carrying useful diagnostic information when Init fails. This has the
2393 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2394 "z39.50/oclcui.asn", where its definition is somewhat different from
2395 what OCLC document on their web-site, as required to interoperate with
2398 Support for anonymous authentication in yaz-client. Use the command
2401 * Fix the OID of the Index Data-local "admin" Extended Service from
2402 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2403 the 1000, which indicates a locally-defined OID, was a mistake.
2405 --- 2.0.3 2003/06/20
2407 Fix CCL directive @case handling so that it affects string match for
2408 both CCL keywords and qualifiers.
2410 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2411 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2412 Decoder has been updated with ASN.1 changes as listed in
2413 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2414 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2415 z_IUUpdate, remains unchanged.
2417 ZOOM_record_get may now return a record in a specific character set.
2418 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2419 "from" is the character set of record as returned by target. "to" is
2420 the character set to be returned. If omitted, "to" is UTF-8.
2422 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2424 New ODR utility, odr_getelement, which returns name of element for
2425 which encoding/decoding failed.
2427 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2428 in cases where a required element was omitted.
2430 Bug fix: some MARC8 sequences were not converted.
2432 New ZOOM option "step" which specifies number of records to be
2433 retrieved in one chunk. Used in conjunction with "start" and "count".
2435 SRW support for yaz-client. Use scheme http: to use it, e.g.
2438 yaz-client no longer does (un)intelligent character set conversions
2439 by default. Can be enabled with charset and marc_charset commands.
2441 xmalloc trace fix for 64-bit systems such as DEC alpha.
2443 Solaris 2.6 compile fix.
2445 New function, cql_strerror() translates SRW error codes, as returned
2446 by cql_transform_error(), into human-readable English strings. Used
2447 in yaz-client diagnostics when appropriate.
2449 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2450 converts it into a type-1 query which is sent to the server. This
2451 makes CQL available for use with all Z-servers, as opposed to the tiny
2452 minority that can handle CQL queries themselves.
2454 --- 2.0.2 2003/04/28
2456 New Debian package layout similar to the Redhat Package layout.
2458 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2459 and search result respectively.
2461 --- 2.0.1 2003/04/25
2463 Redhat package is now several packages: libyaz (runtime libraries),
2464 libyaz-devel (development and documentation, and yaz (utility programs).
2465 Package spec file by Morten Bogeskov.
2467 New member 'schema' in struct bend_fetch_rr which the name of requested
2468 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2469 handler MAY set this to reflect the schema of the returned record.
2471 New member 'display_term' in struct scan_entry. GFS now sets member entries
2472 and allocates scan entries to be filled by user scan handler. In previous
2473 version, entries member was allocated by the scan handler. That still works,
2474 but the GFS will ignore member display_term - assuming it was NOT set by
2475 the handler. The fact that the GFS now allocates the entries both allows
2476 for new members and makes a scan handler easier to write.
2478 Fix CQL lex buffer overflow.
2480 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2481 SRU default recordPacking is string.
2483 SRU protocol support for frontend server.
2485 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2487 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2489 Added scan for the ZOOM shell (zoomsh).
2493 * String Identifers for Schemas (Amendment 5).
2494 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2495 Old definition for schema
2496 Odr_oid *schema; /* OPT */
2501 Z_InternationalString *uri;
2502 #define Z_Schema_oid 1
2503 #define Z_Schema_uri 2
2506 * resultCount parameter to Sort Response (Amendment 1).
2507 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2509 Support for SRW 1.0 over HTTP. This is an optional feature and
2510 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2513 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2514 on the same port. SRW SearchRetrieveRequests are mapped
2515 to bend_init,bend_search,bend_fetch,bend_close.
2517 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2519 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2520 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2522 ZOOM connections are SRW based if schem http is used for hostname
2523 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2524 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2526 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2527 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2528 distance=n, order=true/false, relation=le, prox unit=word. If
2529 n is omitted, distance 1 is used.
2531 Fixed problem with C compiler include path in wrong order.
2533 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2534 on Solaris. Patch from Ko van der Sloot.
2536 New MARC decode API. All new functions operate on a yaz_marc_t
2537 handle. The most important new functions are: yaz_marc_create,
2538 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2539 decode and destroy respectively. Decoder can produce formats
2540 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2541 include/yaz/marcdisp.h.
2543 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2544 to UTF-8, UCS-32, wchar_t or Latin-1.
2546 * Prototypes for yaz_iconv_-functions moved to separate header
2547 include/yaz/yaz-iconv.h.
2549 Make a few private functions 'static' in unix.c. This prevents
2550 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2552 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2553 are set when Init Response is received.
2555 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2556 but returns diagnostic set as well.
2558 New function yaz_strerror which is a portable wrapper for
2559 strerror/strerror_r/GetLastMessage.
2561 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2562 is returned for MARC. If type is "oai", then OAI MARC is returned.
2564 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2567 --- 1.9.2 2002/11/26
2569 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2571 Fix bad race conditions on SIGTERM and terminate gracefully in
2574 Move retrieval (data1) module to Zebra since nobody seems to be
2577 Add GRS-1 render for ZOOM using same format as yaz-client.
2579 --- 1.9.1 2002/10/05
2581 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2583 Fix broken ESpec handling in data1 module.
2585 SGML reader parses comments and makes them part of the data1 tree.
2587 Added several type casts so that YAZ compiles as C++ code.
2589 ZOOM didn't handle PDU encoding failures properly.
2591 Added more Bib-1 diagnostics (approved extensions).
2593 GNU configure: better check for iconv.
2595 More portable use of accept, getpeername. Check for socklen_t. Use
2596 int/size_t if socklen_t is not defined.
2600 PQF parser rejects bad queries - including those with extra
2601 characters in them. PQF parser used to silently ignore that.
2602 Cleaner API for PQF added, which allows you to get detailed
2603 error information for bad queries (see yaz/pquery.h).
2605 Fixed bug in ZOOM_record_get for type "database".
2607 Implemented mini iconv library supporting conversions between
2608 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2610 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2612 --- 1.8.9 2002/08/20
2614 Fixed ZOOM C record cache so that preferredRecordSyntax and
2615 elementSetName is used to check for already fetched records.
2617 --- 1.8.8 2002/08/02
2619 Added three members in bend_initrequest structure to facilitate
2620 character set negotiation.
2622 Fixed a bug in frontend server that could cause indefinite
2623 loops under rare conditions.
2625 Revised character set utilities (charneg.h) so that encoding
2626 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2628 For PQF, directive @term <type> sets term type for Scan/Search.
2629 Here <type> is general, string, numeric, null. The term type
2630 is inherited - just like @attr.
2632 New call odr_set_charset that sets character set conversion for
2633 international-strings on a ODR stream. Prototype is:
2634 int odr_set_charset(ODR o, const char *to, const char *from);
2635 The InternationalString is still represented as C string in YAZ
2636 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2637 won't). On the protocol level, you can use any encoding.
2639 Support for UNIX sockets in ZOOM.
2641 Solaris recv sometimes returns errno == ENOENT. It is treated as
2642 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2644 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2645 both client and server. Code by Morten Bogeskov.
2647 --- 1.8.7 2002/05/22
2649 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2650 that they can be used directly from Visual Basic. You must recompile
2651 your windows APP if you're using ZOOM.
2653 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2654 Commands "lang" and "charset" sets language and character set respectively.
2655 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2656 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2658 Attributes from multiple CCL fields may be OR'ed rather than merged
2659 using directive "@field or". Fields are still merged by default -
2660 equivalent to "@field merge".
2662 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2665 Fixed bug in zget for parameter ExtendedServicesResponse.
2669 --- 1.8.6 2002/03/25
2671 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2673 Client displays USR.1:SearchResult-1 (hits per term).
2675 Additional Search Info for search in Generic Frontend Server.
2677 Fixed CCL parsing of "field=s".
2679 WIN32 installer - using the excellent NSIS software from nullsoft.
2681 Fixed CCL parsing of "field = - <number>".
2683 Added function yaz_marc_decode that decodes MARC for line mode
2684 display or XML (similar to that used by JZKit).
2686 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2687 Z39.50. But ISO/ILL was, however.
2689 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2690 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2692 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2693 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2695 --- 1.8.5 2002/02/03
2697 New YAZ client features: Command completion and new commands:
2698 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2699 Code provided by Jacob Poulsen.
2701 New call oid_trav, that visits all registered OIDs via callback.
2703 Function ZOOM_record_get now returns const char pointer rather than
2704 void pointer. It saves a lot of type casts.
2706 For YAZ client, command "auth" now allows you to set authentication
2707 in IdPass style. It is enabled when three tokens are given - order
2708 is user, group and password.
2710 Fix memory leaks in MARC record handling for ZOOM.
2712 New option for YAZ client, -k <kilobytes> that sets
2713 maximum record size. Similar to -k option for generic frontend
2714 server and yaz-ztest.
2716 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2718 Prefix query parser reports "fail" when bad attribute set is given.
2720 Fix in MARC decoder. Proximity logging. Fix for attribute set
2721 in scan handler for server. Patches by Shigeru Ishida.
2723 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2726 Configure option --with-openssl=<dir> now works when a directory is
2727 specified. Patch provided by Morten Bogeskov.
2729 New option for YAZ client, -u <auth>, that sets authentication.
2731 ZOOM fix: error information was sometimes "missing", since error
2732 was cleared/reset too when it shouldn't.
2734 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2736 --- 1.8.4 2002/01/04
2738 Scan for ZOOM API. New object ZOOM_scanset. New functions
2739 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2740 ZOOM_scanset_destroy.
2742 New ZOOM function, ZOOM_connection_last_event, that returns type
2743 of last event (such as "receive data", "send data", "apdu received",
2746 New ZOOM option, schema, that specifies schema for retrieval.
2748 New CCL feature. Qualifiers can be aliases for one or more
2749 other qualifiers (if more than one is given, OR is used).
2751 ZOOM uses named result sets if target supports it.
2753 Two new YAZ client commands: . (dot, which sources a script of YAZ
2754 client commands), and ! (to execute shell command.). Implemented
2757 Working on Debian packages.
2759 --- 1.8.3 2001/11/19
2761 YAZ client enables named result sets only if target supports it.
2763 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2765 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2766 with key="host" to get same result.
2768 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2769 Function Z3950_resultset_record(s) returns references to records
2770 "owned" by resultset. To become owner use Z3950_record_clone.
2772 Function z_ext_record handles Extended Services. Thanks to
2775 --- 1.8.2 2001/11/12
2777 CCL Parser fix: ignore token comma when dealing with and-lists.
2779 Documentation updates for COMSTACK.
2781 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2782 Changed prototype Z3950_records. For some functions, int parameters
2783 were changed to size_t.
2785 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2788 New MARC decode/display function, marc_display_exl, which properly rejects
2789 non-ISO2709 records. YAZ client uses it.
2791 --- 1.8.1 2001/10/29
2793 Fix bug: local attribute set wasn't set correctly in PQF strings.
2797 * Old Z39.50 codecs no longer supported.
2799 Added ZOOM C binding. See http://zoom.z3950.org/
2801 Renamed states for COMSTACKs to avoid confusion with events.
2803 Implemented cs_look and proper cs_rcvconnect.
2805 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2807 Configure detects POSIX threads on OpenBSD.
2809 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2810 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2812 When error is returned from present handler, non-surrogate diagnostic
2813 is returned in present response (and fetch handler is no longer called).
2815 * Minor adjustments to pquery parser (PQF). Token characters may be
2816 escaped by using backslash (C-style).
2818 PQF parser allows string attribute values to be specified. For @attr,
2819 non-numeric characters after the equal-sign are treated as strings
2820 (e.g. @attr 9=title).
2822 CCL trunction character may be defined (@truncation in file)
2824 * function zget_ExtendedServicesRequest sets waitAction to
2825 waitIfPossible (was wait).
2827 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2830 CCL operator names may be set in field definition files (CCL_bibset).
2831 See ccl/bib1 for an example.
2833 Fixes in ASN.1 compiler for C++ compatibility.
2835 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2836 and "op_or" to avoid conflict with C++.
2838 Fixed problem with GNU readline detection on Redhat 7.0.
2840 Added step-size for Scan backend handler.
2842 Fixed bug that made the frontend server crash when no attribute
2843 set was specified for scan.
2845 Front-end server automatically switches to original working directory
2846 when installed as an NT service. Previously -w had to be specified to
2849 Added extended attributes for retrieval module (data1), so that data1
2850 records carry d1_readXML/SGML attributes. d1_read also supports
2851 null-data rules ( <tag/>)
2853 On UNIX when POSIX threads are available, a separate library libyazthread
2854 is created. Programmers should link with that library and the yaz library
2855 when using threads. The reason for the split was that some applications
2856 on Linux, such as Apache, doesn't work well when using shared objects that
2859 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2860 (or any frontend server) in SSL mode by specifying ssl: followed by
2861 address. Only tested on UNIX.
2863 Added feature for CCL module. Virtual structure s=al or s=ol generates
2864 and-list and or-list respectively instead of phrase search.
2868 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2869 log_mask_str. This was done to avoid name conflicts with other libraries
2870 (such as other PHP extensions).
2872 Added raw OID member for preferred record syntax (request_format_raw)
2873 and returned record syntax (output_format_raw) for backend fetch method.
2875 Config file yaz-config now accepts options so that it returns specific
2876 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2878 Shared library support for UNIX using GNU libtool.
2880 * Modified backend interface. Request/Response struct's replaced by
2881 one read/write C struct. For example bend_fetchrequest and
2882 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2883 Every handler - even search has to be registered in bend_init
2884 handler. This means that the YAZ library no longer refers to
2885 external functions and it makes it possible to make the whole
2886 thing a single DLL/SO.
2888 Added Segment handler for backend server.
2890 Added Zmbol/Zebra administrative functions to YAZ client.
2892 Threaded frontend server on UNIX (when POSIX Threads are available).
2893 Starting the server with option -T enables multi-threading.
2897 Added configure option --enable-comp/disable-comp to control use
2898 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2899 located in sub directory asn.
2901 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2902 in ${exec_prefix}/bin along with the other programs yaz-client and
2905 GNU automake used to maintain makefiles.
2907 Added several OID's.
2909 Changed retrieval module so that we can load records with no abstract
2910 syntax defined. Tagpaths in these records are fully composed of string
2913 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2917 On UNIX, the generated makefile now supports a proper 'make install'.
2918 The prefix can be set via GNU configure to set the install location
2919 (default is /usr/local).
2921 * YAZ programs client and ztest were renamed to yaz-client and
2922 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2923 locations, such as /usr/bin,/usr/local/bin,etc.
2925 * YAZ Header files were moved from include to include/yaz. YAZ Header
2926 files are referred to as include <yaz/log.h> rather than <log.h>.
2927 The YAZ include path (-I ..) is therefore the same as before. Programmers
2928 should update their #include statements or use -Ipath/include/yaz
2929 instead. The main motivation for doing this change is that YAZ header files
2930 can be installed in "standard" locations /usr/include,/usr/local/include
2931 without introducing conflicts, since ALL YAZ header files are stored
2932 in subdirectory yaz (under /usr/include for example).
2934 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2935 rather than project/workspace files. We switched because project files
2936 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2939 Changed name of logging function, logf, to yaz_log, to prevent name
2940 clash with some math-log functions. The YAZ header log.h defines logf
2941 to yaz_log (#define) so there should be no incompatibilities by this
2944 Added bend_start/bend_stop handlers for server. These handler are
2945 called on start/stop of server. For windows they are called whenever
2946 a service is started/stopped.
2948 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2949 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2950 in util/yc.tcl. The auto-generated C code structures are, in a few
2951 cases, incompatible with the old decoders. There are differences in the
2952 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2953 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2954 The preprocessor variable ASN_COMPILED is defined when the compiled
2955 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2956 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2957 wish to use the old encoders/decoders you can specify --disable-yc
2960 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2961 version so that it supports both new - and old version of DB Update
2963 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2964 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2965 change. The name parameter can be set to 0 in which no name is specified
2966 for the construction. The macros odr_implicit and odr_explicit sets name
2967 parameter to zero for the construction involved. New macros
2968 odr_implicit_tag and odr_explicit_tag are similar to the others,
2969 except that a name parameter is added. For programmers' that don't use
2970 ODR they probably only need to change the call to z_APDU and z_External.
2972 Added access control facility by interfacing the TCP wrapper library.
2973 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2974 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2975 name of the daemon and enables the access control as specified in
2976 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2978 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2979 den Dool <H.M.vdnDool@kub.nl>.
2981 Added reference ID parameter to most functions in server API - refer
2982 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2984 Changed name of ccl library to libccl.a (was ccl.a).
2986 Fixed bug in decoder for Explain (Category TargetInfo).
2988 Added support for GNU readline in client. Thanks to Jacob Poulsen
2989 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2991 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2992 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2993 IMPLEMENTATION! This change was made to the development version before
2994 the ZIG decided to retract the amendment. If any users MUST be
2995 compatible with the original Update definition, PLEASE CONTACT US, and
2996 we will include a separate definition corresponding to the old Update
2997 ES. Note that because of the change to the ASN.1 of the
2998 TaskPackageRecordStructure we cannot define a single structure that
2999 will support both versions.
3001 * Added const modifier to buffer parameter for some ODR/BER encoding
3002 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3003 completeWAIS, odr_dumpBER.
3005 Fixed bug in client.c which caused a crash when a scanResponse didn't
3006 contain positionOfTerm.
3008 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3009 * will cause an error in a client if a non-YAZ target sends both a
3010 * list of Scan entries and non-surrogate diagnostics.
3012 Retrieval module enhancements. Tag sets may be typed in the reference
3013 to it. From the .abs-file the "tagset" directive takes a third optional
3014 integer type for the tag set referenced. From a .tag-file the "include"
3015 directive takes a third optional type as well. The old "type" directive
3016 in the tag set itself is still recognized but acts as the default type
3019 Backend interface change. Individual Scan terms returned from bend_scan
3020 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3021 in include/backend.h.
3023 Retrieval module enhancements. Multiple tag sets and attribute sets may
3024 be specified in abstract syntax specs. Revised the error/warning for
3025 logging messages reported by the retrieval module when reading the
3028 Object Identifier system (oid_..) changed. The API is backwards
3029 compatible but the oid-routines now allocates new OID's when needed.
3030 Raw OID's may be specified in oid_getvalbyname.
3032 YAZ now uses GNU configure to generate Makefile(s).
3034 * Minor changes in some of the member names of DeleteResultSetRequest and
3035 DeleteResultSetResponse. See include/proto.h.
3037 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3038 and added member 'languages' in TargetInfo (which was missing).
3040 Changed the way attribute sets are handled in the retrieval
3041 module. These are now cached, just like the abstract syntaxes
3044 Changed YAZ so that it links with compiled ASN.1.
3046 Added Explain-schema definitions and mapping routines. The following
3047 Explain categories have been implemented: AttributeDetails,
3048 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3050 Fixed minor bug in Windows version of Server Library.
3052 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3054 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3056 Added EXTERNAL: UNIverse Resource Report (non-standard).
3058 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3059 ENUMERATED and SET OF.
3061 * Added 'const' to some of the char pointer arguments for the
3062 functions, data1_read_node, data1_getelementbytagname,
3063 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3066 Fixed bug in data1_insert_taggeddata - the last_child member of
3067 parent wasn't initialised.
3069 * Changed data1_read_record and data1_read_node so that the supplied
3070 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3071 doesn't refer to any parts of the "SGML"-buffer.
3073 Fixed bug in server library (Windows version of statserv_remove).
3075 * Changed code so that it compiles as C++. The type definition
3076 of Odr_fun which is a member of Odr_arm was changed. The result is,
3077 that an explicit typecast is needed for the fun pointer when
3078 using Odr_arm - as in:
3079 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3081 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3083 Implemented the new structured date and time definition as approved
3084 by the ZIG. Added schemaId element to the specificTag in Espec-1
3085 (also approved at the last ZIG). Thanks to RVDM.
3087 Added some Object identifiers (RVDM).
3089 Changed the Update Extended Service (RVDM).
3091 Added command "refid" to client which specifies referenceId for
3092 the following requests.
3094 Implemented extended service handling for server. See ztest.c
3095 for an example as well as backend.h. New handlers are registerd
3096 in the Init handler.
3098 * Changed interface for sort in server.
3100 Added new members to statserv_options_block. It allows a server
3101 to read options from another source than just the command line. Thanks
3102 to Charles Woodfield.
3104 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3105 renamed to zboolean. Some C++ compilers complained about the name.
3107 Minor changes to gils.abs. Added index 's' (sort) on title
3108 and date/time-last-modified.
3110 --- 1.4pl2 1998/1/30
3112 Fixed bug in server library regarding inetd mode (-i). This bug
3113 was introduced by release 1.4.
3115 --- 1.4pl1 1998/1/29
3117 Added sort facility in client and backend server interface.
3119 Fixed problem with dependencies in Makefile(s).
3121 Fixed bugs for encoders/decoders of extended services and
3124 Implemented sub-tree feature for schemas. Sub-trees are
3125 referenced in *.abs-files. See explain.abs for an example
3126 of the use of this feature.
3128 Modified bib1.att; local attributes for ANY didn't include
3129 ANY itself (only affects use of the retrieval module).
3131 Fixed bug in plain SGML reader in function data1_read_node:
3132 tags with prefix "var" was incorrectly interpreted as variants.
3134 Added feature "sub-schemas" to enable references to - and definitions
3135 of - group of elements.
3137 * Removed member parent from type data1_element (in data1.h).
3139 Implemented function odr_nullval() that returns the value of
3142 * Removed member num_children from data1_node (in data1.h).
3144 Made NT service interface part of the server library. The
3145 function statserv_main uses the NT service when required and
3146 calls the statserv_start / statserv_close routines.
3148 Routine zget_SearchRequest and zget_PresentRequest fills
3149 resultSetName/Id member with "default" instead of "Default".
3151 Fixed memory leak in server. Request queue member wasn't freed.
3153 Fixed nmem_exit so that memory is freed.
3157 Revised the CCL parser utility to be thread safe.
3159 Added function, oid_ent_to_oid, to replace the function
3160 oid_getoidbyent, which is not thread safe.
3162 * Added nmem_init and nmem_exit to initialize and release
3163 NMEM resources. Function nmem_init should be called once in the
3164 initial thread before NMEM/ODR is used. statserv.c and client.c
3165 have been changed accordingly. The change was necessary to make
3166 NMEM thread safe. The NMEM memory pool is shared amongst threads
3167 in a process. Unix-based applications will still work fine without
3170 Added NT Services interface for the the Z39.50 (statserv) Server.
3171 Refer to the ztest.c source on the usage.
3173 Windows 95/NT port using MSVC5.0. Project files are included in the
3176 * Defined new 'global' handle for the retrieval (data1) system. The
3177 new handled, data1_handle, describes the state of the data1 system.
3178 This handle is passed as first argument to virtually all
3179 data1 related routines. The functions data1_create and data1_destroy
3180 creates and destroys a data1 handle respectively.
3182 Added ODR encode stream member to all backend request structures
3183 init, search, scan etc. This stream should be used to allocate all
3184 memory used for the response when thread safe operation is needed.
3186 Changed the comstack utility, cs_addstr, to be thread safe. The
3187 returned hostname string returned by the function is now part the
3190 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3191 function. The cs_straddr takes a COMSTACK handle as argument, so this
3192 function must be used after cs_create and before bind/connect.
3193 This function is thread safe.
3195 Moved test server to 'ztest' directory - generic server code still
3196 in 'server' directory.
3198 Made prefix query (pquery.c) utility thread safe.
3200 Added new function modifier YAZ_EXPORT to 'export' public DLL
3201 functions when using windows (see include/yconfig.h).
3203 Added definitions to the OID database (util/oid.c) (RVDM).
3205 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3207 Added call to ccl_rpn_delete in client program.
3209 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3210 release of RPN structure.
3212 Added support for C++, headers uses extern "C" for public definitions.
3213 With input from RVDM.
3215 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3216 Thanks to Ronald van der Meer (RVDM).
3218 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3220 Added support for private extensions to the OID database
3221 (oid_setprivateoids()). Thanks to RVDM.
3223 Added optional, physical ANY (key replication)
3225 Fixed null-reference problem in GRS-1 output filter.
3227 Proximity operator added to Prefix Query Format (PQF).
3229 In test client command "base" accepts multiple databases.
3231 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3235 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3237 Smallish bug-fixes in the new encoders/decoders (explain).
3239 Bug fixed in DeleteRequest.
3241 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3243 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3245 Added SOIF syntax (using private OID for now) to retrieval module and client.
3247 Added Update extended service.
3249 Added SearchResult-1 additional info structure.
3251 Added optional CCL (ISO8777) interpreter as separate module. Available
3254 --- 1.2 1996/6/10 (1st anniversary release)
3256 Added Summary record syntax. Lightly tested.
3258 Added OPAC record syntax. Untested.
3260 Added ResourceReport service encoders/decoders. Untested.
3262 Fixed bug in z_Unit - wrong tagging on unitSystem.
3264 Fixed bug in the DiagRecs decoder.
3266 Added options for max PDU size and session timeout to frontend-server.
3268 Added documentation of query-language parsers and other supporting utilities.
3270 [frontend-server] Added Attribute set to the bend_scanrequest API.
3272 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3273 surrogate diagnostics were generated.
3275 [retrieval] Allow multiple local values for attribute.
3277 [retrieval] Allow multiple attributes per element in .abs files. index type.
3279 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3281 --- 1.1pl2 1996/4/10
3283 Minor changes, mostly specific to Zebra's requirements (retrieval)
3287 Repaired bug in frontend server when running multiple listening
3288 endpoints in dynamic mode.
3290 z_External() now won't break if a known, ASN.1 value comes encapsulated
3291 in an octet-string. The value will pass through unmodified in an Odr_oct.
3293 Added a bit of code to the demo client to decode & display
3294 ASN.1-structured records represented in the octet-aligned branch of
3295 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3297 Added z_ext_getentbyref() to the ASN module. Doc updated.
3299 * Completed the SCAN definition in the ASN module. This may break SCAN
3300 code based on older YAZ-versions at compile-time. The fix is easy -
3303 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3304 under the SCAN definition. Remember to initialize this, server-people.
3306 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3307 that this does not extend to ODR and ASN.
3309 Comstack allows insertion of established socket (primarily for
3310 inetd-operation of servers). Doc updated.
3312 Front-end server can now start from the inetd in TCP mode. Doc
3315 --- 1.0pl4 1996/1/24
3319 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3320 the rank and record number.
3322 Adjustments to the frontend server.
3324 Fixed diagnostic BER dumper. It ignored the file argument.
3328 Various changes to retrieval module.
3330 Changed the union discriminators of the protocol files from enums to
3331 ints paired with #defines.
3333 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3336 *Changed operator in the RPN structure to 'roperator', again to avoid a
3339 Fixed problems in Explain decoders/encoders.
3341 --- 1.0pl2 1995/12/6
3343 Memory bug in log module fixed.
3345 --- 1.0pl1 1995/12/5
3347 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3349 Bug in Explain DatabaseInfo module fixed.
3351 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3355 The shift to v1.0 signals that we now consider the *core* functionality
3356 of YAZ reasonably stable (the core being more or less equivalent to
3357 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3358 tested (Explain not at all - though that will happen soonish).
3360 Minor changes to code to support Windows port.
3362 Various minor changes after we're getting to use GRS-1 & co. more.
3364 Added Espec-1 format.
3366 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3367 of the protocol and it cannot be selected when encoding (maps into 'string'
3368 when decoding). Needed to talk to some servers.
3370 Demo client can request simple element set names.
3372 Added Diagnostic Format encoders/decoders.
3374 Added simple Close handling to frontend server (no hooks for resource
3375 reporting yet), and demonstration client.
3377 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3379 --- 1.0b3 1995/08/24
3381 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3382 handled incorrectly when records were requested in the searchResponse. This
3383 will only affect you if you use the frontend-server.
3385 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3386 Test-client will ask for and print GRS1. Ztest will return dummy records
3389 Added Explain encoders/decoders to the service-level API. Untested.
3391 Added Extended Services: Item Order encoders and decoders to the Service-
3392 level API. Untested. We could use a recent copy of the pertinent bits
3393 of the ILL protocol to add those bits.
3395 Added diagnostic format 1 encoders/decoders to the service-level API.
3398 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3399 odr_cons.c, which causes a more correct output.
3401 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3402 was always set to 0 when no records were requested in the searchRequest.
3404 * Added better external-handling. This shouldn't harm old code that
3405 *encodes* externals. It can break code that looks for a
3406 'single-ASN1-type' representation, since those types that are known
3407 are now decoded immediately. Look at the SUTRS sample code in
3408 seshigh.c and client.c. Documentation updated.
3410 Handling of structured records in bend_fetchresponse. Length -1 marks
3411 structured record, type is deduced from format field.
3413 --- 1.0b2 1995/06/27
3414 Fairly quick maintenance release to add SUTRS support.
3416 Fixed handling of SUTRS records in the demonstration client.
3418 * Added format field to the bend_fetchrequest and bend_fetchresponce
3419 structures of the backend API (frontend server). When the record is
3420 returned, the value of the format field is mapped to an OID. The
3421 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3422 of the record. The special value VAL_NONE in the bend_request means
3423 that no specific format was requested by the client. Documentation
3424 updated accordingly. Test server (ztest) will return a fixed dummy
3425 SUTRS record if your client requests SUTRS.
3427 Documentation updated accordingly.
3429 You can now set external libraries and RANLIB support in the top-level
3433 First public release.
