3 ISO2709/MARC parse most octet aligned records; not just those that
4 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
5 MARC parse more records instead of just dumping as is. YAZ-670
7 ZOOM: proper caching for variations of record schema. YAZ-671
9 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
17 New utility z_get_HTTP_Response_details - an extended version of
20 New utility yaz_url_get_error which returns error message of last
21 failed yaz_url_exec call.
23 yaz-url and url functions: allow max HTTP redirects to be controlled.
25 New functions yaz_file_glob2, yaz_xml_include_glob.
26 These functions takes a flags parameter, which, for now only controls
27 whether to fail inclusion of a non-existing file (without glob
28 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
32 For MARC XML parsing, allow record without leader. A fake/default leader
33 is inserted and a warning is tagged with the record.
35 ICU: fix leak in in icu_iter_get_org_info.
39 ICU: fix bug in icu_iter_get_org_info (un-init variable).
43 Implement z_HTTP_header_remove.
47 ICU: Disallow 0 ptrs for some ICU string utilities.
49 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
50 returns original tokens (before normalization).
52 CCL: avoid z39.58/regex truncation when not needed. Apply only the
53 conversion of those masks, when absolutely necessary.
55 CCL: configurable masking character - @mask. Default masking character
58 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
59 full response anyway, so a Transfer-Encoding header will obstruct the
64 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
65 picking a socket. Problem is that some systems has IPV6 support, but
66 we can't create sockets for them, so we pick AF_UNSPEC first.
68 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
69 use content_len to determine resulting Content-Length in HTTP response
70 and NOT Content-Length supplied in headers by user.
72 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
73 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
75 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
78 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
79 with big endian and unsigned char (by default).
83 Fix yaz-client connect (crash in 4.2.55).
87 Fix proxy/host problem for ZOOM that could occur if unix sockets
90 New Debian package libyaz4-dbg.
92 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
93 differently in tcpip_close.
97 Windows installer of YAZ includes YAZ4J as a component.
99 CQL: allow "extra terms" again, by default. Thus, the CQL parser
100 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
101 and earlier. CQL parser may operate in strict mode where queries
102 not conforming to the standard BNF are rejected (syntax error).
103 Whether the CQL parser operates in strict mode is controlled with
104 cql_parser_strict . Strict mode enabled with option -S for utilities
105 cql2pqf and cql2xcql .
107 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
109 --- 4.2.53 2013/04/10
111 New charset, MARC-8c, which is like MARC-8 but allows control characters
112 0x01 through 0x1F, except ESC to be passed through verbatim.
114 Fix a problem with duplicate sub field character in MARC output. Problem
115 happened only when output was MARC-8 encoded.
117 --- 4.2.52 2013/04/03
119 yaz-ztest: Use hash for fake hit count. Before, random number was used.
120 This is problematic for unit tests using yaz-ztest. This patch also makes
121 a hash for CQL queries. For RPN, any term with a leading digit will be
122 treated as pseudu hit count (to force any particular hit count by a client).
124 yaz-ztest: return unique MARC dummy records. Beyond record offset
125 24, the author surname is patched with offset to make all records
128 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
129 on system wide default (/proc/sys/net/ipv6/bindv6only).
130 @4 binds to IPV4 only. @6 binds to IPV6 only.
132 Update CQL API documentation a bit
134 CQL: don't accept extra terms for queries. Makes the CQL parser
135 stricly conformant to the standard.
137 --- 4.2.51 2013/02/12
139 GFS: scan handler gets extra_args from request and may return extra
140 response data . That's for SRU only.
142 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
144 --- 4.2.50 2013/01/30
146 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
148 OPACXML: sync spelling of availabilityDate in XML to that of Schema
149 opaxxml.xsd. The schema had the correct spelling of this member always.
150 The ASN.1 was mis-spelled and still is (API change) - we are
151 not changing this. However, the OPAC to XML conversion had yet
154 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
157 New function, z_ext_record_oid_nmem, which is similar to
158 z_ext_record_oid but takes NMEM rather than ODR
160 --- 4.2.49 2013/01/18
162 ICU: New conversion element 'join' which joins tokens into one
163 with a custom character given by rule attribute.
165 --- 4.2.48 2013/01/10
167 New GFS search member: present_number. This is a hint to the
168 search handler how many records are going to be fetched immediately
169 following search. There's no guarantee that it's going to be the case,
170 since it depends on hit count (for Z39.50 piggyback) and whether errors
173 Make a few functions static (private). The functions getbyte_stream,
174 ungetbyte_stream and yaz_gets are now private. They were never declared
177 yaz-marcdump: exit(5) for serious decoding errors
179 ISO2709 decoding: be more picky WRT header
181 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
182 was only used as to indicate that next-result-set-position should be
184 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
185 Based on patch from Ashley Sanders.
187 Make some functions static/private in PQF parsing. Those functions were
188 never declared in a public header and so should not be in use by
189 applications based on YAZ.
191 --- 4.2.47 2012/11/23
193 ZOOM: special options to control APDU logging.
194 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
195 logging of APDUs until "saveAPDU" option is set again. If logging is
196 already enabled the effect is that current APDU buffer is cleared.
197 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
198 logging (default behavior on new connection).
199 The APDUs sent/received can be obtained by using
200 Using ZOOM_connection_option_get(c, "APDU") or
201 ZOOM_connection_option_getl(c, "APDU", &l).
203 GFS: relay implementation_version from backend
204 From 3.0.40 and later, implementation_version from backend was
205 not used in init response at all.
207 --- 4.2.46 2012/11/15
209 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
210 mode at all. Probably never did.
212 Make a new version of ztest.pem that, at least, is not expired.
214 --- 4.2.45 2012/11/13
216 Fix description of CCL directive 'case'.
218 More tight checking of form arguments (yaz_uri_to_array). Makes
219 YAZ better at rejecting big and/or bad POSTs.
221 SRU decoding does not report more than up to 10 invalid arguments.
223 rpn2cql: less quotes in generated terms. Semantics unchanged, but
224 it's prettier this way.
226 --- 4.2.44 2012/10/25
228 New utility yaz_decode_init_diag. Defined in proto.h.
230 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
231 given for unix local socket.
232 The COMSTACK string for doing so is:
235 unix:/myfile:tcp:localhost:9999/mybase
236 unix:/myfile:localhost:9999/mybase
237 unix:/myfile:http://fakehost/mybase
239 debian: Use dpkg-buildflags in build process.
241 --- 4.2.43 2012/10/19
243 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
244 global's SRU service uses a recordPosition scheme starting from zero.
245 First record's position should be one
246 according to the standard.
248 --- 4.2.42 2012/10/18
250 Allow more namespaces for SRU. This is to allow, for example, an
251 incorrect namespace returned from server
252 http://services.igi-global.com/sru .
254 Minor fixes for compilation on Windows.
256 --- 4.2.41 2012/10/11
258 daemon: log total number of bad signals from child on stop so that it
259 is more easy to spot problems with child worker processes.
261 retrieval: empty backend name attribute omits element set
262 from being used in retrieval.
264 --- 4.2.40 2012/10/04
266 Implement Solr sort strategy "solr", similar to sru11 sorting.
267 This will implement the correct parameters on Solr requst to do
270 --- 4.2.39 2012/09/28
272 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
275 MARC: Extra/missing indicator handled for MARCXML.
276 The indicator length is given in header and is the same for the
277 whole record. If attributes ind1, ind2 are missing, then content
278 character defaults to blank. Extra indicator attributes (beyond)
279 indicator length are treated as an error.
281 Reformat: delete trailing whitespace
283 --- 4.2.38 2012/09/17
285 MARC: fix non-ASCII characters for leader. This is to ensure we can
286 generate XML in UTF-8.
288 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
289 in one node with structure word.
291 --- 4.2.37 2012/09/04
293 yaz-json-parse: JSON output may be pretty printed by using option
296 Increase default value of max message for Z39.50 Init for GFS, ZOOM
297 and yaz-client. Old value was 1 MB. New value is 64 MB.
299 --- 4.2.36 2012/08/22
301 yaz-client: don't display bogus records from SRU servers. Some SRU servers
302 return more records than given by *maximumRecords*. Skipping those in
305 record_render: simplify buffer return handling and fix at least one bad
306 memory reference, that broke the test_embed_record sometimes.
308 Allow http://user:pass@host notation for yaz_url_exec.
310 zoomsh: allow shell command to be executed. Via the system(3) call.
312 yaz_poll: Allow num_fds == 0
314 yaz-client: fix bad encoding of "itemorder item". The itemorder
315 item <no> - command forgot to use length of encoded Item Request
316 package. Error present since YAZ 3.
318 yaz-ztest: fix bad usage of session handle. Bug was introduced when
319 result sets were saved (271a9c83).
321 SRU recordPacking: guess record packing in response rather than looking
322 at the recordPacking element which, OF COURSE, changed semantics in SRU
325 Decode SRU 2.0 responses. The official namespace for responses, according
326 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
327 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
328 nature.com's server, however, usee namespace
329 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
330 we are now using a glob-expr to match up the namespace. ZOOM C and
331 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
332 I can not find a single real example showing the "real" namespace in
333 the documentation from OASIS. The namespace for requests is different
334 from responses, but this is not added to YAZ yet, when we don't encode
337 --- 4.2.35 2012/06/26
339 zoom/record_render: add support for Base64 decoding fo MARC records
340 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
341 which will decode base64 + ISO2709 marc-8 encoded material from text node
344 --- 4.2.34 2012/06/07
346 Add missing definitions ZOOM_resultset_get_facet_field_by_index
347 and ZOOM_resultset_facets_names.
349 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
352 Change APDU dump printing to avoid long leading blanks. For levels 16
353 or larger the level is shown and the indentation is truncated but
354 recursed with modula 8. This makes it still reasonable easy to read
355 - even for nested BER dumps.
357 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
358 return 0 (incomplete package) in case where the BER package was
359 considered too nested (return value of -2).
361 dumpber: lines of level 15 are not indented further. Two spaces per
362 indentation; indentation 15 or more is indented to a fixed indentation
363 and augmented with a level=<no> indication.
365 zoomsh: increase max size of command+args
367 GFS: No limit in RPN buf size in CQL to RPN conversion.
369 --- 4.2.33 2012/05/09
371 New function for daemon utility, yaz_daemon_stop .
373 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
375 --- 4.2.32 2012/04/25
377 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
378 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
380 --- 4.2.31 2012/04/23
382 YAZ daemon utility relays SIGUSR1 to child process.
384 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
385 would result in en empty database list - which in turn would result in
386 encoding failure for search.
388 Fix reading beyond string in yaz_sort_spec.
390 --- 4.2.30 2012/04/11
392 Add two new SRU diagnostics:
393 236: Access to specified database denied
394 1015: Init/AC: Maximum number of simultaneous sessions for Userid
396 Document the very useful ZOOM-C option "apdulog".
398 CQL to RPN: term may be passed through verbatim. This is enabled with
399 truncation.cql . The assumption being that the term is already CQL.
401 --- 4.2.29 2012/03/20
403 record_conv: leader spec may be given for marc element.
404 The leader spec is given as attribute leaderspec for element marc.
405 For example to convert a MARC21 record from MARC-8 to UTF-8:
406 <marc inputformat="marc" outputformat="marc"
407 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
409 record_conv: allow user-XSLT params. For example:
410 <xslt stylesheet="MARC21slim2DC.xsl">
411 <param name="myparameter" value="myvalue"/>
412 <param name="otherparameter" value="othervalue"/>
415 record_conv: fix error handling for missing marc charsets.
417 CQL: fix extra terms in wrong order.
419 --- 4.2.28 2012/03/06
421 record_conv: modify new API for conversion types. The conversion types
422 may be passed in new functions yaz_record_conv_configure_t and
423 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
425 Avoid mixed statement/variable declare; fixes compilation with Visual
428 --- 4.2.27 2012/02/28
430 Add non-standard SRU diagnostic: 235: "Database does not exist".
431 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
432 Update SRU to Bib-1 diagnostic maps accordingly.
434 CCL: add two new diagnostics for unsupported masking. The new
435 diagnostics are: "Embedded truncation not supported" and
436 "Single charcacter mask not supported".
438 --- 4.2.26 2012/02/23
440 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
442 --- 4.2.25 2012/01/11
444 Build YAZ for Ubuntu Oneiric.
446 CCL: allow parantheses for proximity operands. For example CCL query
447 (a) % (b) is now allowed.
449 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
450 marked dead, rather then being destroyed. If not, the session memory is
451 being free'd before the search/scan handler is finished. Also destroy
452 'request' memory in request_release rather than in various places,
453 which resulted in leaks from time to time.
455 --- 4.2.24 2011/12/21
457 cql_sortby_to_sortkeys: honor sort prefix.
459 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
460 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
461 The rpn2cql family of functions now always returns quoted CQL terms.
463 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
465 --- 4.2.23 2011/12/15
467 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
468 sequence is treated as one. For example, &&a=b&&&c& is identical to
471 --- 4.2.22 2011/12/05
473 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
474 APDUs for a connection to a WRBUF.
476 --- 4.2.21 2011/11/23
478 Fix cql_sortby_to_sortkeys. Completely broken before.
480 Make CCL's @truncation work again.
482 --- 4.2.20 2011/11/09
484 New ZOOM connection setting: tproxy. It's like proxy, but does not
485 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
486 to set resolved address + port for a connection outside ZOOM itself.
488 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
490 --- 4.2.19 2011/11/07
492 Fix uninitialized variable in Solr spell support (could cause SEGV
493 for SRU response decoding).
495 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
496 back-end's addinfo through into the ZOOM response addinfo.
498 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
499 they are separated by a colon and a space rather than simply
502 --- 4.2.18 2011/10/28
504 Add support for Solr spell-checking/suggestions through ZOOM.
505 If a Solr target has been configured correctly for spelling-checking
506 and suggestions, these will now be returned on the ResultSet option
507 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
509 --- 4.2.17 2011/09/28
511 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
512 with a flag whether to substitute escape sequences or not.
514 --- 4.2.16 2011/09/22
516 Fix nmem_strsplit_escape to substitute escape char properly.
518 New option for zoomsh -e , which makes it abort on first error and
519 return process exit code to indicate success/failure.
521 YAZ options utility supports special option -- which makes all it treat
522 all following arguments as non-options.
524 --- 4.2.15 2011/09/16
526 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
527 searched if absolute filename is given.
529 Fix conv_xslt() error-reporting when stylesheet is not found.
530 (The value of fullpath is meaningless in this situation.)
532 --- 4.2.14 2011/09/07
534 Fix problem in CQL sort node creation: un-initialized memory.
536 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
537 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
538 CQL sortby depending on whether Type-1 or CQL is actually sent to the
541 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
542 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
544 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
545 will make it possible to use both single-character mask (#) and wildcard (?)
546 in CCL . Throw diagnostic for left truncation because that is not supported
549 --- 4.2.13 2011/09/01
551 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
552 cases using escapes (\-sequences) and masking.
554 PQF parse fix: A trailing backslash followed by end-of-string (\0)
555 would result in a read one byte beyond string.
557 rpn2ccl may use Z39.50 masking for terms (t=z).
559 ICU check fix. Don't include library -lCrun on Solaris, unless present.
561 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
562 not --cppflags (which seeems like an error in icu-config).
564 --- 4.2.12 2011/08/27 RPM package only
566 cql2ccl: fix conversion of terms: operator characters were not
569 --- 4.2.11 2011/08/25 RPM package only
571 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
572 CCL parser will map both # and ? to their regular expression
573 quivalents (. and .*).
575 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
576 of reserved CQL characters.
578 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
579 is, so that they are passed through.
581 --- 4.2.10 2011/08/24
583 ZOOM SRU mode: more aggressive re-connect.
585 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
586 made available as a utility function, declared in <yaz/logrpn.h>
588 rpn2cql_structure() supports proximity nodes (except that the Type-1
589 proximity node's "exclusion" binary is ignored, as there is no way to
590 express that in CQL). Fixes bug #4564.
594 Fix SEGV that could occur if set command of zoomsh was given without
595 value (2nd argument).
597 Fix SEGV that could occur if unsupported transport was given for
598 COMSTACK - say https (when SSL was unavailable).
600 Build yaz-url on Windows too.
604 New utility to get web content. Header is url.h. A command line tool
605 yaz-url is part of the distribution and packages.
607 Fixes for SSL COMSTACK (when gnutls is in use).
609 New functions yaz_base64{encode,decode}. Header is base64.h.
613 ZOOM C includes HTTP response buffer as additional info if it fails
614 to decode the SRU response.
616 Make wrbuf_json_puts available.
620 zoom: throw diagnostic for invalid value for option "sru". Before a
621 bad SRU request was sent.
623 Adding new utility wrbuf_vp_puts.
625 Add cclxmlconfig.obj to win/makefile. It was missing completely.
629 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
630 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
631 redirect was used at the same time.
633 MARC line mode decoding: be less picky about length given - first
634 5 digits of header that is.
636 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
638 Changes to decoding of SRU records: a record with recordPacking=xml is
639 modified with a new root element <yaz_record> if the recordData contains
640 multiple children elements. This is to make the record XML parseable
643 RPN to Solr conversion: encode special characters.
645 Generic Frontend Server: fix uinitialized member, stepSize.
649 Fix a bug in SRU decoding of records.. The database records stored
650 had un-initialized memory, but it would only be seen with yaz_record_render
651 and type_spec="ext" .
653 Fix a bug in ccl_qual_dup introduced in 4.2.3.
657 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
661 Add new utilities to convert from CQL to CCL . These utilities have
662 prefix cql_to_ccl defined in cql.h.
664 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
665 lead to memory heap corruptions when ICU utilities were in use.
669 Make compilation work without Libxml2.
671 yaz-client: remove redundant blanks in display of searchResult-1 term
676 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
677 resulting CQL node (tree) in a new node CQL_NODE_SORT.
679 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
680 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
681 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
682 Note that the CQL sortby spec is only converted when the GFS is already
683 converting from CQL to RPN (cql2rpn element).
685 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
686 specify whether to collapse delimitors or not. The existing nmem_strsplit
687 do collapse (collapse parameter = 1).
689 Windows installer: For NSIS, set InstallDir depending on x86/x64.
691 Rename internal func yaz_use_attribute_create. While non-static, this
692 function is not declared in a public header.
696 Add -lCrun when linking with ICU on Solaris.
698 More quicks character set conversions for OPAC records.
702 fix problem with record_render: records were converted (character set
703 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
707 SRU: add methods for handling DADS SRU-proxy facets.
709 Separate OPAC record character set for ZOOM_record. yaz_record_render
710 allows a character set given as charset=from/opacfrom,to where 'from' is
711 the character set of a bibliographic record, 'opacfrom' is character set
712 of OPAC record and 'to' is the target character set.
716 yaz-client: show may XML format records. Command show followed by 'format'
717 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
720 src/stemmer.c: Avoid using unnamed union. It is not supported by some
723 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
726 Update yaz.spec to operate on both SLES11 / Centos 5.5.
728 RPM: Release includes 'indexdata' name. Use indexdata in release name so
729 this package can be distinguished from other vendors.
731 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
732 as determined by configure
734 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
736 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
737 returns no error and no record, the present request is considered
738 partial (only a subset of the records could be returned by backend), and
739 so it is appropriate to set Present Status to partial-4.
743 Move yaz-config man pages to section 1.
745 More documentation about Solr.
747 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
748 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
749 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
750 peers on some Linux systems. However, in general that does not work
751 so YAZ can not rely on that to work. Debian changed behavior in this
752 respect from Debian lenny to Debian squeeze (still testing as of Oct
754 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
756 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
760 Fix yaz-config output: echo_source not set correctly by configure.
764 Solr Web Service support for yaz-client and ZOOM.
766 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
768 --- 4.0.12 2010/08/17
770 Z39.50 facet support. Facet specifications are passed for search in
771 other-information with ASN.1 as defined in facet.asn and OID
772 .10.1000.81.5 . Facets are expressed as an Attribute list as known
773 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
774 3 is limit (number of entries to get in response). yaz-ztest returns
775 dummy facets if a client asks for them.
777 --- 4.0.11 2010/07/09
779 CCL fixes: bug 2895 and bug 3539.
781 GR1-display: add comma in display - was removed by mistake in
784 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
786 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
788 --- 4.0.10 2010/06/18
790 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
791 result set from a connection. The result set will be on its own
792 thereafter; no operations on it will perform retrievals from a target.
793 Only cached copies are returned.
795 ZOOM C:fix case for HTTP servers responding with Connection:close.
796 Ensure that if there is a current task it is resumed (like fetching
797 more records in a result set) . Bug #3484.
799 PQF parser: use odr_atoi for Odr_int (not atoi)
801 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
802 values that contain any non-digits are treated as string attributes
803 (previously decoding only checked for leading character ([0-9]). PQF
804 encoding: attribute string values are not surrounded by double-quotes.
808 New utility for managing threads - thread_create.h.
810 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
811 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
812 but YAZ' implementation do.
814 Fixes for yaz_cond-functions on Windows 7.
816 DLL export more symbols.
818 zoomsh: show record do NOT render opac.
820 Remove *.la files from Debian and RPM packages.
824 Debian package libyaz-dev depends on libgnutls-dev again (was
825 removed in YAZ 4.0.6, but due to Libtool it is still needed
826 even though yaz-config do not list libgnutls libs).
828 ZOOM: Use only one WRBUF for returning string results for
829 ZOOM_resultset. Reduces memory usage for ZOOM in general.
831 ZOOM: ZOOM_connection do not use a shared pointer to
832 ZOOM_resultset after ZOOM_resultset is destructed by
833 user. Reverts to YAZ 4.0.4 behavior.
837 record-conv: fix problem with at least one XSL conversion -
838 due to probably incorrect usage of XML XSL documents.
842 Fix yaz-config for static mode and the use of SSL (gnutls).
846 Forward decl timeval struct in mutex.h and gettimeofday.h.
848 yaz-config: fix 'static' mode linking.
852 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
853 are wrappers for pthreads or Windows. For Windows these are put in
854 a separate DLL: yaz_cond4.
856 libyaz.la (whole source) is compiled with thread. If thread support
857 is enabled enabled, all source of YAZ is compiled with treading support.
858 This allows core utilities such as yaz_log to use thread facilities.
859 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
860 thread utilities. This commit moves mutex utilities (mutex.c) from
861 libyaz_server.la to libyaz.la.
863 yaz-json-parse displays leading text until error.
867 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
868 patch from Giannis Kosmas.
870 SRU: no longer URL encode SRU database. The URL for an SRU server is
871 a URL and such is alreeady encoded - at least when given with leading
872 http:// or https://. This reverts behavior to YAZ 3.0.50.
874 Support for new MARC XML notation TurboMARC which like MARCXML is a
875 complete representation of MARC/ISO2709.. This one, however, is more
876 compact and allows for faster processing with XSLT. TurboMARC can be
877 used in the marcdisp.h API, from the yaz-marcdump utility and from
880 yaz-ztest can be configured - via the database - to perform certain
881 delays when it performs operations search, present and single record
882 fetch. This allows testers to make yaz-ztest act as a real or even slow
883 Z39.50 server. Refer to the yaz-ztest man pages for details.
887 wrbuf_destroy allows NULL WRBUF passed to it.
889 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
891 Add ZOOM_connection_close.
893 No fixed size buffers for ZOOM shell - bug #3257.
895 tstodr: make it work on s390 platform.
897 New icu iterator-functions. The new icu_iter-functions makes it possible
898 to use ICU chains from many threads.
900 yaz-client: better syntax check for show command.
904 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
907 New simple local-file XML include facility which allows file glob-patterns.
908 Refer to yaz/xml_include.h.
910 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
913 ZOOM_record_get supports new parameter "format" which makes it format XML
916 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
917 JSONText in ECMA-262) is JSONValue, not JSONObject.
921 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
922 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
924 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
925 POSIX/Unix builds .so with major version 4.
927 Remove old LOG_-defines from log.h. They have been obsolete and
928 undefined by default for the last 5 years.
930 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
932 GFS: Remove socket (int *fd) from search_rr handler. The socket
933 descriptor ptr is a facility that allowed a search handler to supply
934 a socket which would serve as a callback - when search was complete.
935 This facility has now been in use for years.
937 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
938 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
939 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
940 returns 'const char *' rather than 'char *. The returned string is
941 read-only and should not be modified by applications. COMSTACK cs_close is
942 now a void function - it no longer returns int. No applications check for
943 the value and the implementations has always returned 0.
945 ZOOM: use size_t for scan hit counts and str size. Functions
946 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
947 occ (hit count) and len (string length) are now of type size_t pointer
948 rather than int pointer. This is to be able to represent large hit counts
949 and to also just to use the proper type for string length (strlen result).
951 New JSON parser. Refer to include/yaz/json.h .
953 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
954 Used to be int in some cases. Many wrbuf_-functions used to return an int
955 indicating some length.. These return values were never used. And so they
958 ODR: odr_malloc, odr_total now takes size_t for size.
960 clone_z_type: fix leak; occurred for encoding failures.
962 --- 3.0.52 2009/12/03
964 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
965 bug was introduced in 3.0.51.
967 --- 3.0.51 2009/12/02
969 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
971 tcpip comstack: fix leak for getaddrinfo.
973 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
974 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
975 Decoding of SRU "path" database is performed by private function
976 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
977 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
979 yaz-client: honor base command for SRU. Change when database setting
980 is applied for SRU and ensure it is kept when a connection is reset.
981 Change also the way errors are displayed or SRU (decoding of packages).
983 --- 3.0.50 2009/11/02
985 Add support for extra request / response data for SRU codecs and GFS.
986 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
987 for extra data response buffer and length. For the GFS, both request
988 and response data (XML) is carried in extra_args and extra_response_data
989 for the search handler. Patch by Ko van der Sloot.
991 ZOOM: For queries that cannot be converted to the specified rpnCharset,
992 ZOOM now returns a diagnostic on the client-side ('invalid query' /
993 10010). This fixes bug #2113.
995 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
996 cmdfile included a 'quit' command that would result in a memory violation.
998 --- 3.0.49 2009/10/01
1000 Make a number of functions defined in xmlquery.c static. These have
1001 never been declared in a public header file (yaz/xmlquery.h) and was
1002 made public by mistake.
1004 Improve speed of character conversions (iconv utilities). This makes
1005 conversions from MARC-8 faster.
1007 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1008 unless type desired is "raw". This will prevent type "xml" from
1009 returning ISO2709 .. Which obviously can not be XML parsed.
1011 Fix memory leak in ZOOM that would occur if option apdulog was used
1012 on a re-used connection.
1014 Frontend server logs HTTP requests.
1016 Frontend server now sends Z39.50 close when it times out (sesssion has
1017 been idle for too long). Versions 2.0.30 and earlier also sent close.
1018 But due to a mistake this was disabled in all versions after that, i.e.
1019 the server would just close the socket immediately.
1021 yaz-client emits a better message when receiving an unrecognised
1022 userInformationField.
1024 Skip zero-length subfields when decoding ISO2709. This rare case happens
1025 if a record has two FS characters in a sequence. Without this patch
1026 there would be a reference beyond char array in using_code_len fragments
1029 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1031 --- 3.0.48 2009/08/28
1033 The show command offered by the zoomsh command now takes a 3d optional
1034 parameter type which is what is passed to ZOOM_record. If the type
1035 argument is omitted, "render" is used.
1037 RPN to CQL conv may use USE string attributes (bug #2978).
1039 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1041 --- 3.0.47 2009/07/08
1043 Function yaz_xml2query allows a diagnostic element in the PQF XML
1044 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1045 code and additional info respectively.
1047 The BER BOOLEAN is now the integral type Odr_bool which still happens
1048 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1049 typedef'd to Odr_int. This is still an integral 'int', but it may be
1050 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1051 ASN-1 compiler as well as programs has been updated to use the new types.
1053 --- 3.0.46 2009/06/08
1055 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1056 only the bibliographic record was rendered. For type=opac, an OPAC
1057 record is only returned if it is present.
1059 iconv: small fix for encoding of advancegreek.
1061 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1063 yaz-client: option auto_reconnect=on really reconnects.
1065 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1067 server: avoid null ptr ref for for yaz_poll errors.
1069 build: fix RPM build for RHEL 5.3.
1071 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1073 --- 3.0.45 2009/03/31
1075 Fixed bug #2709: TCP connect returns Invalid argument.
1077 Fixed compilation for mingw.
1079 Honor charset for raw records (ZOOM_record_get).
1081 Fixed use of errno for threaded mode that was seen on Solaris 10.
1083 Fixed argument passing with blanks in value for Windows Service.
1085 Disable YAZ' own log rotate by default (no 1 GB limit).
1086 The variable l_max_size which specifies the log file limit is set to 0
1087 (DISABLED): This is due to the fact that YAZ is most often deployed using
1088 logrotate. Also YAZ can not perform log rotate because of unsufficient
1089 permissions (setuid).
1091 --- 3.0.44 2009/02/17
1093 List supported encodings in man page for yaz-iconv.
1095 Fixed missing SSL libs for --libs output
1097 Re-established OID record syntax application-xml. Nobody should use it
1098 but we don't want to change soname because of this symbol being absent.
1100 --- 3.0.42 2009/02/02
1102 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1104 Added member named_result_sets for init handler struct for the GFS. This
1105 allows a server to disable named result sets.
1107 Removed OID record syntax application-xml.
1109 Added support for rule-based transliterator for ICU wrapper of YAZ.
1111 Fixed bug #1902: yaz-icu XML output.
1113 Make YAZ checks Emacs friendly.
1115 BITSTRING value shows value. Bug #2346.
1117 ISO2709 decoding: skip control characters from indicator data.
1119 Omit sort key by default in yaz-icu's output.
1121 Allow combined single char options (again) for YAZ' options function.
1123 Utility yaz-marcdump got option to display YAZ version (-V).
1125 Allow YAZ to use ICU 3.4.
1127 Added new ICU test case which illustrates removal of diacritics.
1129 --- 3.0.41 2008/12/29
1131 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1133 --- 3.0.40 2008/12/29
1135 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1138 Fixed bug #2352: yaz-marcdump crashes for certain record.
1140 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1142 Added support for Danmarc2 to UTF-8 conversion.
1144 Added support for ISO5426 to UTF-8 conversion.
1146 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1147 implementation version.
1149 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1151 --- 3.0.38 2008/11/10
1153 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1154 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1156 ZOOM C now interprets databaseName option for ZOOM connection as path
1159 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1161 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1163 Dummy Libxml2 types no longer defined in headers of YAZ'.
1165 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1168 --- 3.0.36 2008/09/26
1170 Various ODR chapter fixes.
1172 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1174 Added missing source for Windows compilation, mutex.c.
1176 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1178 For SRU connections in ZOOM all records up to "count" are now fetched.
1180 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1181 in Windows due to bad error handling for Libxml2.
1183 Added facility for sending arbitrary records (ASN.1 any) using
1184 ZOOM C's Extended service update. Patch by Sam Reynolds.
1186 New options for ZOOM C's connection, logapdu which makes ZOOM log
1189 --- 3.0.34 2008/06/18
1191 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1193 --- 3.0.32 2008/06/12
1195 Fixed memory violation that could occur when decoding UTF-8. This bug
1196 was only present in 3.0.30 of YAZ.
1198 --- 3.0.30 2008/06/06
1200 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1201 GNU TLS is used by default (if found).
1203 yaz-ztest returns OPAC records if a client asks for OPAC.
1205 Improved speed of MARC-8 encoding.
1207 Added support for lossy and loss-less MARC-8 encoding.
1209 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1211 Added new Windows Service wrapper (sc).
1213 yaz-client's itemorder command may now send a file.
1215 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1217 Added new function yaz_log_xml_errors.
1219 Allow (but warn) unknown XML attributes in MARCXML parsing.
1221 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1223 The UTF-8 to MARC-8 conversion now uses a different set of characters
1224 for Greek symbols. Bug #2120.
1226 --- 3.0.26 2008/02/21
1228 Added yaz_daemon (daemon.h).
1230 Fixed bug #2068: pkg-config trouble
1232 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1234 --- 3.0.24 2008/01/28
1236 Document --with-xml2 option.
1238 Added OPAC XML XSD (etc/opacxml.xsd).
1240 Allow glob mask for name attribute in retrieval element for the
1241 generic frontend server's retrieval facility.
1243 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1244 except POLLIN/POLLOUT.
1246 Fixed error handling in cs_listen. Bug #2037.
1248 --- 3.0.22 2008/01/20
1250 Fixed version in yaz/yaz-version.h.
1252 Fixed bug #2027: Crash when closing connection.
1254 Changed configure so that ICU support is only enabled if only ICU
1255 and Libxml2 is available (because the ICU chain is XML based).
1257 --- 3.0.20 2008/01/15
1259 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1260 is built. Only this DLL depends on the ICU runtime.
1262 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1263 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1265 Changed license of CCL module to 'Revised BSD'. After consultation with
1266 remaining members of the original EUROPAGATE consortium, we are re-issuing
1267 the CCL module without a separate license. The software was developed by
1268 Index Data as part of a research project. The special license was included
1269 to help feed usage information back to the project consortium to support
1270 project evaluation. At this time, the project consortium has long-since
1271 disbanded, and the majority of the original principals have retired. At the
1272 same time, we have significantly modified the software during the following
1273 years, to the point where very practically no original code remains. To
1274 simplify re-use of the software, we have contacted those members of the
1275 consortium who could be reached, and agreed to re-issue the module as a
1276 proper part of the YAZ package.
1278 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1280 CQL closer to being version 1.2 compliant. CQL also allows free-form
1281 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1284 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1285 bug could make Extended services handling crash in the ZOOM layer. This
1286 bug was only present in YAZ 3.0.18.
1288 --- 3.0.18 2007/12/19
1290 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1293 yaz-marcdump reads and writes collection wrapped records.
1295 Handle OPAC for record conversion module.
1297 Fixes for ICU wrapper.
1299 Allow ICU libs to be controlled with --with-icu .
1301 --- 3.0.16 2007/11/12
1303 Added yaz_poll which is a wrapper for select/poll. When poll is available
1304 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1305 sockets to be in use.
1307 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1308 functionality through an XML based configuration (ICU chain). This system
1309 is useful for search facilities such as Pazpar2 and Zebra that needs to
1310 perform tokenization of indexed material. The ICU code in a separate
1311 library libyaz3_icu.a.
1313 Added HTTP tunnel facility for COMSTACK, bug #1752.
1314 This is a facility that allows a Web proxy, such as squid, to tunnel
1315 Z39.50 traffic. This facility is "transparent" to must applications
1316 using YAZ. It's enabled by using pseudo transport connect: followed by
1317 the proxy address, followed by command, then follwed by he regular
1318 "virtual" addresss. For example,
1319 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1321 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1323 --- 3.0.14 2007/09/21
1325 Fixed bad memory reference in ZOOM_record - cuased by member not being
1326 initialized. This was a problem only in YAZ 3.0.12.
1328 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1329 fields were not removed.
1331 Changed the way C code is generated from codetables.xml. Made a MARC-8
1332 conversion trie for each characterSet section rather than codeTable.
1333 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1334 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1336 --- 3.0.12 2007/09/12
1338 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1339 from ZOOM_record_error).
1341 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1343 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1345 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1347 Better SRW-to-Bib-1 diagnostic mapping.
1349 ZOOM C and yaz-client announces SRU version 1.2 by default.
1351 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1354 Fixed in yaz_sru_decode to allow other version than 1.1.
1356 --- 3.0.10 2007/08/22
1358 Added support for SRU scan for ZOOM.
1360 Added support for the use of the older versions or Extended Service
1361 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1362 set to the version , 1=first, 2=second, 3=third. The third version is
1363 what ZOOM C has used so far. And that, obviously, is the default.
1365 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1366 therefore in Zebra and in SimpleServer-based applications). The new
1367 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1368 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1369 which is passed into the back-end search callback function.
1371 Added support for HTTP Basic authentication in clients: the SRU/W
1372 codec encodes the username/password elements of the PDU structure
1373 appropriately, and these may be set using the "user" and "password"
1374 options in ZOOM-C applications (the same options that are used for
1375 Z39.50 authentication).
1377 --- 3.0.8 2007/06/25
1379 Fixed bug #1208: SSL appears to be broken in ZOOM.
1381 Fixed bug #1206: Libxml2 include path weirdness.
1383 Added oid_name_to_dotstring.
1385 Allow elementSetName to be specified for ZOOM C record update.
1387 Allow waitAction to be specified for ZOOM C based for Extended Services.
1389 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1390 syntax OID. Bug introduced in YAZ 3 series.
1392 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1394 --- 3.0.6 2007/06/06
1396 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1397 directory. yaz-client now reads commands from file given by option -f
1398 if specified; then tries to read .yazclientrc in current directory.
1399 Failing that, it reads .yazclientrc from user's home directory.
1401 Added support for correlationInfo Note and ID for Record Update via
1404 Added yaz-client command querycharset which specifies character set for
1405 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1406 (termListAndStartPoint).
1408 Charset ISO5428:1984 is an alias for ISO5428-1984.
1410 Implemented a way to perform scan in a result set using Z39.50. This
1411 is achieved by attaching the result set name in the characterInfo
1412 (type InternationalString) of OtherInformation in the Scan Request PDU.
1413 The result set is identified in the otherinformation by the new OID:
1414 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1415 This allows for scan in result set and faceted search . Zebra did some
1416 of this in the APT term using attribute type 8 and value being result
1417 set. Using the OtherInformation approach for this is cleaner and easier
1418 to work with in proxies and the like. This facility can be used in
1419 yaz-client using new command setscan which takes a result set as first
1420 argument, start position (APT) as second.
1422 Changed decoding of SRU XML packed records to deal with servers that
1423 have recordData with XML data with multiple root nodes. Also make
1424 comparison for recordPacking case insensitive. Again, one server
1425 returns "XML" where others return "xml".
1427 For SRU responses allow Content-Type application/xml as well as text/xml.
1429 --- 3.0.4 2007/05/21
1431 Fixed bug in character set conversion of BER strings. Bug introduced
1434 --- 3.0.2 2007/05/08
1436 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1438 For OID class, use oid_class consistently.
1440 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1443 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1444 character set for bibliographic information interchange". By Giannis Kosmas.
1446 Added documentation on new OID API.
1448 --- 3.0.0 2007/05/02
1450 Changes to generic frontend server interface: added new member
1451 'query_charset' for bend_initrequest structure. A backend init handler
1452 should set this member to its native character set for query terms.
1453 When defined, the frontend server logic will announce this character set
1454 to a client if the negotiationModel bit is set by the client. All server
1455 implementors are encouraged to specify this. If a backend server does not
1456 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1458 Added CCL utility to remove terms (stop words) from resulting RPN
1459 tree. This is handled by functions with prefix ccl_stop_words_ .
1461 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1462 terms in RPN queries.
1464 Clean-up the CCL API. Moved some internal structures from ccl.h to
1465 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1466 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1467 This is replaced by ccl_parser_find_str which takes a string instead.
1469 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1470 libyaz.la is the core of YAZ except the generic frontend server and
1471 does not depend on POSIX threads anymore. libyaz_server.la is the
1472 generic frontend server facilities and uses POSIX thread functionality
1473 if available. The libyaz.la no longer depends on POSIX threads because
1474 the number of global structures is limited. NMEM no longer re-uses blocks
1475 between threads ; it simply free's memory immediately but allocates in
1476 "large" chunks as usual. We don't expect any performance penalties
1477 because of this. The yaz_log system is still using a global log_level so
1478 caution must be taken when modifying it with yaz_log_init_.. +
1479 yaz_log_mask_str. This, however, should not cause any trouble because
1480 these functions are called during initialization of application code
1481 anyway. `yaz-config --libs server` returns libs for server applications;
1482 `yaz-config --libs` returns libs for non-server applications.
1484 New OID database - with public definitions in oid_db.h. Removed old OID
1485 database including the head oid.h and definitions such as enum oid_value
1486 and struct oident. The new OID database uses the same string names as
1487 before but the 'protocol' is gone. There are now only two representations
1488 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1489 converts from string to OID; functions with prefix yaz_oid_to_string
1490 converts the other way.
1492 Change to emit_term() in CQL-to-PQF query translation: when a term has
1493 the /regexp relation modifier, do not process it for leading and
1494 trailing "^" and "*", which have quite different meanings in regular
1497 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1498 write handlers no longer carries a 'last' parameter. This will make
1499 yaz_iconv flush "less" characters. A flush is performed by call to
1500 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1502 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1503 removed, because function yaz_query_to_wrbuf does the same.
1505 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1506 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1508 Deprecated MARC utility functions removed.
1510 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1513 Branch split: YAZ_2_1_55_branch
1515 --- 2.1.54 2007/03/16
1517 Fix to ZOOM-C so that transparent reconnection is properly handled on
1518 connections that are in asynchronous mode.
1520 Fixed compilation on OpenBSD 4.0.
1522 Large strings in GRS-1 records are now properly displayed in yaz-client.
1524 Added character conversion support for "advancegreek"; based on patch from
1527 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1528 sequence is met. Before the error was not set so it would be unknown.
1530 Adjust yaz-marcdump MARC reader so that it skips until record separator
1533 --- 2.1.52 2007/03/07
1535 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1536 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1537 fd_set structure used as a bitmask for the FDs to be selected on.
1539 Using ACX_PTHREAD macro to check for POSIX threads.
1541 Fixed have-vsnprintf check.
1543 --- 2.1.50 2007/02/23
1545 Fixes for configure on BSD. Bug #900.
1547 Added snprintf/vsnprintf wrappers for systems that don't have
1548 limits (heavens forbid).
1550 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1551 created before all previous tasks were completed and removed from the
1552 task queue, the new task could be removed by a mistake.
1554 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1556 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1558 Fixed bug #832: Problem with MARC/charset in yaz-client.
1560 Fixed bug #668: save command line history for yaz-client.
1562 Fixed bug #830: pkg-config support.
1564 --- 2.1.48 2007/01/23
1566 Extended ZOOM result set options with two options that may be read by
1567 a client: resultSetStatus and presentStatus with values as specified for
1569 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1571 Fixed bug #827: Using SSL fails on Debian etch.
1573 Fixed bug #826: Weird looking chars for set of MARC records.
1575 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1576 that is treated as an ItemOrder with itemRequest being an XML document
1577 external. The value of "doc" is the content.
1579 Extended the GFS search facility. New member of bend_search_rr
1580 'estimated_hit_count' signals that hits is known to be an estmate
1581 (higher or lower than real hit count). New member 'partial_resultset'
1582 signals that the search was partial (hit count is lower or equal than
1583 real hit count). For Z39.50, the information is stored in resultSetStatus
1584 member of SearchResponse APDU. For SRU, the information is signalled
1585 via SRU diagnostic 59: "Result set created with valid partial results
1588 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1590 --- 2.1.46 2007/01/13
1592 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1594 Added ZOOM_connection_peek_event.
1596 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1597 the following new functions:
1598 ZOOM_event_nonblock, ZOOM_connection_process,
1599 ZOOM_connection_get_{socket,mask,timeout},
1600 ZOOM_connection_fire_event_{timeout,socket}.
1601 The existing blocking event handler, ZOOM_event, is a wrapper for the
1602 + blocking ZOOM_event_sys_{poll,select}.
1604 Implemented function ccl_xml_config which parses XML version of CCL
1605 configuration (bug #798).
1607 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1609 Added timings utility (yaz/timing.h)
1611 --- 2.1.44 2007/01/03
1613 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1616 Fixed bug #779: Rotation of apdu.log fails.
1618 Fixed for character set conversions:
1619 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1620 Honor G1 set in MARC-8 decoding.
1622 --- 2.1.42 2006/12/17
1624 Fixed bug #775: char conversion does not handle Alternative UTF-8
1627 Implemented function yaz_marc_read_line which parses MARC line format
1628 records. There is a wealth of formats out there. So far, this function
1629 reads line records produced by yaz_marc_write_line.
1631 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1632 more generic and easier to remember(!) options: -i format and -o format
1633 which specifies input format and output format respectively - where
1634 format is one of "marc", "marcxml", "line", "marcxchange".
1636 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1637 does not print anything except warnings for records.
1639 For yaz-marcdump, added support for MARC split into files (-s) with a given
1642 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1643 spec, at http://www.loc.gov/standards/sru/record-update/
1644 This has changed the binary layout of the following structs:
1645 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1646 bend_update_rr . Patch by Ko van der Sloot.
1648 Added GFS utility function bend_assoc_is_alive which returns 1 if
1649 association is still alive (client is connected); 0 otherwise (client
1650 closed connection). This allows busy servers to stop working for
1653 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1654 been a separate piece of software. This version of ziffy has been modified
1655 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1657 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1659 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1660 Client code may now interrogate options such as "init_opt_sort" to
1661 find out whether the server claims to support various options.
1663 --- 2.1.40 2006/11/27
1665 Added utilities yaz_{set,get}_esn to set/get element set name from
1668 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1669 of YAZ and has been so since YAZ 2.1.10.
1671 Implemented ZOOM_record_error which returns error information for
1672 record (surrogate diagnostic).
1674 --- 2.1.38 2006/10/31
1676 Updates for SRU Update by Ko van der Sloot:
1677 1. Changed name from "operation" to "action"
1678 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1679 versions in the code, marked as 'backward compatible'.
1680 3. Added diagnostics for SRU Update.
1682 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1684 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1686 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1688 For GFS, fixed problem with SRU diagnostic 'First record position out of
1689 range' being issued for 0 hits.
1691 zoomtst10 part of Windows Build.
1693 --- 2.1.36 2006/10/13
1695 Implemented yaz_filepath_comp which splits a path into file path
1696 components (required by Zebra 2.0.3+).
1698 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1699 BSD inspired license until now so this should not have any real impact on
1700 anybody. See http://www.opensource.org/licenses/bsd-license.php
1702 Fixed bug #687: Missing log lines.
1704 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1707 Fixed bug #689: SRU diagnostics to be added.
1709 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1710 whether a connection is idle (no more work do do).
1712 --- 2.1.34 2006/10/04
1714 Change type of optval from long to int for invocation of setsockopt with
1715 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1717 Added support for specifying the max log file size for the Generic
1718 Frontend Server. The size is given with option -r.
1720 --- 2.1.32 2006/09/21
1722 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1724 --- 2.1.30 2006/09/17
1726 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1729 Fixed bug in Generic Frontend Server that could cause a server to stop
1730 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1732 For the generic frontend server, the maximum record size is used as maximum
1733 size of incoming packages (SRU + Z39.50). The value until was previously
1734 only used in Z39.50 Init negotiation and, later, in a session controlled
1735 sizes of records returned. This is controlled using -k option. It can be
1736 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1738 --- 2.1.28 2006/09/04
1740 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1743 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1745 New option for yaz-marcdump -lpos=value which allows setting a portion
1746 of MARC header to a certain value.
1748 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1750 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1751 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1753 --- 2.1.26 2006/08/15
1755 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1758 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1760 --- 2.1.24 2006/08/08
1762 Fixed MARC ISO2709 encoding routines to deal with character set
1765 Minor changes to GFS logging. Database included in search request log
1768 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1769 cached/multiple records.
1771 Shared libraries are built by default on Unix+configure.
1773 Changed cql2pqf transformation to use a different evaluation order. The
1774 new order is: always, relation, structure, position, truncation, index
1775 and relationModifier. Old order was: always, relation, relationModifier,
1776 structure, index, position, truncation. Note that the the latter ones
1777 override former ones for identical attributes.. The new scheme means that
1778 it is possible to override any existing attribute with a relationModifier.
1779 And also that it is possible to override everything for the index rule
1780 (except the ones listed in relationModifier). No order is perfect but this
1781 one, we believe, covers more real cases.. The "always" should have been
1782 called "default", since the attributes there can be overridden with all
1785 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1786 compilation phase, but also for yaz-config --cflags output. This allows
1787 us to have public headers with Libxml2 stuff in them . It should also,
1788 eventually, make Libxml2 checks redundant in packages using YAZ, such
1791 --- 2.1.22 2006/06/15
1793 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1794 stored in uri, message and details.. Previously diagnostics were stored
1795 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1796 compatibility.. but he's probably the only one affected, so.
1798 Added support for CCL, compiled on the client side, in ZOOM-C. This
1799 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1800 input; the resulting query objects can be used for for searching with
1801 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1803 YAZ' configure searches for OpenSSL by default.
1805 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1806 SL_CTX_use_certificate_file. See
1807 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1808 for more info. Thanks to Ko van der Sloot.
1810 --- 2.1.20 2006/06/02
1812 Bug #600: SRU GET, POST support for yaz-client. Introduced
1813 command 'sru' which selects method SOAP/GET/POST.
1815 Allow missingValueAction to be specified for the sortspec string -
1816 function yaz_sort_spec. By default, the missing value action is null.
1817 Use ! to specify "abort". Use = followed by stringvalue to specify default
1820 Ensured that Present-handler (if defined) is called in GFS before any call to
1821 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1822 searchRetrieve requests.
1824 Documentation for YAZ is now based on the Docbook XML/XSLT using
1825 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1826 is no longer depending on jade/openjade or docbook-to-man scripts.
1827 PDF is no longer part of the distribution - but can optionally be
1828 made using DSSSL/jadetex or FOP.
1830 Added retrieval handling support in Generic Frontend Server to support
1831 conversion between MARC/XML as well as XSLTtransforms. See
1832 etc/yazgfs.xml for an example.
1834 Added Authentication support to Generic Frontend Server in SRU
1835 mode. Authentication using HTTP Basic is supported, as is the use
1836 of 'x-username' and 'x-password' parameters in the request itself.
1838 Added support for a new character set MARC8s identical to MARC8 except
1839 that it converts combined characters to single Unicode characters in the
1840 Latin-1 range (when possible).
1842 --- 2.1.18 2006/04/24
1844 ASN.1 compiler 0.4: generates brief Doxygen file header for
1845 generated .h/.c files.
1847 Utility yaz_iconv now supports conversion to MARC-8.
1849 New facilities for the MARC module. The reading - and writing of
1850 content are separate methods for the yaz_marc_t handle. The following
1851 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1852 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1853 format). Write functions have prefix yaz_marc_write_.. The existing
1854 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1855 available. Removed support for OAI-MARC and simplexml (not the
1856 simplexml from PHP5).
1858 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1859 to be returned for this connection.
1861 --- 2.1.16 2006/03/31
1863 Allow multiple languages and charsets to be specified with
1864 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1865 negcharset iso-8859-1,utf-8
1867 Translation of proximity nodes from CQL into PQF now works.
1869 Moved to automake 1.8, 1.9.
1871 Added function yaz_log_set_handler which allows a log handler to be
1872 installed. This handler will be called for all log messages. Output
1873 to file is also produced; but that can be disabled by passing NULL
1874 fname to yaz_log_init_file.
1876 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1878 For SRW (including GFS), accept application/soap+xml as content-type
1881 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1882 produces NO stylesheet reference even if a default stylesheet is specified
1885 --- 2.1.14 2006/03/14
1887 Updated Windows package to include yazd.dll + yazd.lib for the
1888 Development component.
1890 If the environment variable YAZ_LOG is set, then it is used as a
1891 string indicating the default level of logging to use if not
1892 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1893 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1894 used as before. So, for example, to omit warnings from YAZ logging,
1895 export YAZ_LOG=-warn
1897 cql_transform() now map structure and other attributes before indexes,
1898 so that index-specific structures and other attributes can override
1899 defaults. So now a combination of mapping specifications such as:
1901 index.dc.date = 1=date-modified 4=5
1902 does the right thing.
1904 cql_transform() now also respects the "always" mapping specification,
1905 which establishes an initial set of attributes to be used for all
1906 terms except where overridden by more specific attributes associated
1907 with the index, relation or modifier.
1909 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1910 which mode to use; one of "post", "get" or "soap" (SRW, default).
1912 Fixes for yaz_iconv routines: changed trie-based character set conversions
1913 to use only non-negative values for bit fields due to Sun's C compiler not
1914 supporting negative values.
1916 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1917 sequences where not read correctly. Fix by Rustam Usmanov.
1919 Updated win/makefile to use options, settings which makes things
1920 compile with VS C 2005.
1922 --- 2.1.12 2006/02/01
1924 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1926 In ZOOM socket code, use select instead of poll on MacOSX.
1928 ZOOM-C now support client-side compilation of CQL into RPN that is
1929 sent to the server, enabling CQL to be used against all Z39.50
1930 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1931 ZOOM_query object, and submit it using ZOOM_connection_search().
1932 The CQL-to-RPN translation uses a configuration file, the name of
1933 which must be specified in the Connection's "cqlfile" option.
1935 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1936 function, which takes as its start-term parameter a ZOOM_query object
1937 (which may have had either CQL or RPN set into it).
1940 --- 2.1.10 2005/11/29
1942 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1943 GFS to support this as well. Backend handler, bend_srw_update, does the
1944 update work. Code contributed by Ko van der Sloot.
1946 Allow retrieval of Search Result-1 information in ZOOM by the use of
1947 options that are attached to a result set. ZOOM documentation updated
1950 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1951 UTF-8 conversion. Patch by Raj Patel.
1953 Added option -m to GFS to control formatting of timestamps in log file.
1955 Added 'exit' as synonym for 'quit' in yaz-client
1957 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1958 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1959 for the new members. Patch by Ko van der Sloot.
1961 Added support for SRU POST. It is supported for content-type
1962 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1964 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1965 Instead make the library libyaz.la multi-threaded. Threading as a whole
1966 can still be disabled by configure option --disable-threads. Previosly,
1967 with older GLIBCs there were problems with MT libs under Apache. This
1968 has now been fixed a long time ago.
1970 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1973 CQL module modified to be case insensitive for relations/indexes/operations.
1975 Fixed bug in CQL transform code: incorrect value relationModifieder
1978 Added 'show all' command for yaz-client which retrieves all results
1981 Added new yaz-client, xmles, which takes a (private) OID and
1982 a document to be sent as an extended service request.
1984 Describe new yaz-client commands wait_response and set_auto_wait.
1986 Increase TCP/IP listener backlog from 3 (which I am guessing was
1987 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1988 that the socket will queue as many incoming connections as it's able
1989 to handle ongoing connections. In other words, it will never now
1990 refuse a connection that it would be able to handle merely because
1991 it's not got around to accepting() enough of the pending connections
1992 yet. This is the behaviour anyway under Linux, where the listen()
1993 argument is ignored; but not under BSD and on systems such as
1994 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1995 YAZ-based servers should now be uniform across operating systems in
1998 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1999 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2000 This allows yaz-marcdump to read large MARC batches (>2 GB).
2002 Modified all YAZ source files - except the source which is auto-generated
2003 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2006 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2007 corresponding to the existing *_setl() function. These allow option
2008 values containing arbitrary valuues.
2010 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2011 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2012 except that it returns an indicator of whether or not the sort
2013 criterion was accepted (0 for OK, -1 for invalid).
2015 --- 2.1.8 2005/06/07
2017 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2018 MARC output rather than returning "new" buffer.
2020 yaz-client warns about unknown init options.
2022 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2024 --- 2.1.6 2005/05/24
2026 Added support for SRW sort in Generic Frontend Server. Patch
2027 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2028 sortKeys - or NULL if none is provided.
2030 Fixed bug #307: It was impossible to specify indefinite/no timeout
2031 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2034 Added support for multiple languages and charsets to be specified in
2035 ZOOM. Each charset/language is separated by a blank. If negotiation is
2036 in effect in init-response, Option
2037 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2038 Code based on patch by Vasiliy Osadchuk.
2040 Fixed bug #306: infinite recursion that occurred when calling
2041 yaz_log_level_init as the first call (before other log level or
2044 Fixed bug in scan handling in front end server: if preferred-Position-In-
2045 Response was non-present, a NULL pointer referece was performed.
2047 --- 2.1.4 2005/04/26
2049 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2050 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2051 now defined for all those error codes. So instead of putting 109 in
2052 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2053 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2055 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2058 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2060 Program yaz-client now exits and produces an error message if multiple
2061 Z39.50 servers are specified on the command line (none or one allowed
2064 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2067 --- 2.1.2 2005/03/16
2069 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2071 Fixed bug #272: Preserve spacing for CCL terms.
2073 --- 2.1.0 2005/03/14
2075 Added support for virtual hosts and multiple backend servers for
2076 the YAZ frontend server. The configution is XML based and
2077 support specificition of CQL to RPN mappings and explain information.
2078 See section "Virtual Hosts" in the YAZ manual.
2080 Extended OPAC display utility. OPAC display utility renders
2081 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2082 to supplement yaz_marc_decode_wrbuf.
2084 Fixed a bug in MARC decoder that could caused it to crash for some
2085 invalid MARC records. More diagnostics and warnings where added in
2086 XML output (warnings, etc are stored in comments).
2088 --- 2.0.34 2005/02/08
2090 Fixes for UNIX domain sockets. Bug #261.
2092 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2094 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2095 Added yaz_marc_subfield_str which defines subfield lead string which is
2096 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2097 yaz_marc_endline_str which defines end of fields string used in
2098 YAZ_MARC_LINE format. Default string is newline.
2100 Experimental support for MarcXChange. This format can be produced
2101 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2102 http://www.bs.dk/standards/MarcXchange.xsd
2104 Added yaz-client commands scansize that sets maximum number of
2105 entries to be returned by scan.
2107 --- 2.0.32 2005/01/11
2109 Added support for SRW scan in yaz-client and Generic Frontend Server.
2111 * Added whereInList member to SRW Scan Term.
2113 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2115 Fixed NMEM system to return aligned blocks on the smallest boundaries
2116 that are suitably aligned for all possible types on the particular
2117 architecture YAZ is being built for.
2119 --- 2.0.30 2005/01/04
2121 Fixed numerious warnings that was issued with newer versions of GCC.
2123 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2124 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2127 Make YAZ Generic Frontend Server slightly faster.
2129 Enhance (and reduce) logging for Generic Frontend Server.
2131 Revert YAZ log system so that it flushes every write operation
2132 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2134 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2135 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2136 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2137 will effectively disable old definitions.
2139 --- 2.0.28 2004/11/09
2141 Added yaz_log_time_format which specifies log format using
2144 Added yaz_log_module_level which returns mask for a module. Value
2145 is non-zero mask a if module is enabled; zero if disabled.
2147 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2148 in include/yaz/cql.h.
2150 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2152 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2154 Fixed bug #172: RPM builds does not enable SSL.
2156 Doxyfile.in part of dist. Doxyfile generated by configure.
2158 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2159 are given and the corresponding component does not exist.
2161 Extend CCL documentation in YAZ reference. Describe r=r.
2163 --- 2.0.26 2004/10/01
2165 Fixed MARC->MARCXML conversion to properly deal with
2166 fields, subfields, indicators having non-ASCII characters.
2168 Fixed MARC->MARCXML conversion so that ASCII control characters
2169 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2172 Added YAZ GFS support for conversion from Z39.50 surrogate
2173 diagnostics to SRW surrogate diagnostics.
2175 Bug fix: YAZ GFS did not return schema in explainResponse.
2177 --- 2.0.25 2004/09/30
2179 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2180 now converts recordSchema to elementSetName as well as schema URI.
2182 Fixed bug in COMSTACK that prevented HTTP request packages from being
2185 --- 2.0.24 2004/09/29
2187 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2188 does not require white-space before and after the dash in a range, e.g.
2189 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2192 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2193 due to new GCC removing "redundant" code.
2195 Added yaz-client commands scanpos and scanstep that sets preferred
2196 position and step-size for scan.
2198 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2200 Added CCL utility ccl_qual_buf which parses one or more CCL
2201 spec lines in a buffer.
2203 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2204 of name and value - ignoring empty lines and comments.
2206 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2208 Added odr_get_element_path which returns current element path for an
2209 ODR handle. This utility is useful in error handling or user-defined
2212 Added ODR_PRINT utility odr_set_stream which is is a more generic
2213 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2214 to a write function and pointer to close function. The close function - if
2215 non-NULL - will be called during odr_destroy.
2217 Fixed bug in CCL parser where truncation char was not removed from
2218 right side when truncation=both was in effect.
2220 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2223 --- 2.0.23 2004/08/11
2225 Fix buffer overrun in CQL parser when dealing with proximity (%).
2227 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2228 to UTF-8/UCS conversion is now only based on codetables.xml.
2230 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2232 --- 2.0.22 2004/08/06
2234 Add support for more "commit changes" in ZOOM (uses Extended Services).
2236 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2239 Yet another small fix for configure of SSL.
2241 --- 2.0.21 2004/05/14
2243 Fix SSL libs for configure when --with-openssl=DIR is given.
2245 --- 2.0.20 2004/05/10
2247 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2249 SSL comstack now uses yaz.pem certificate file on server side
2250 by default. Certificate filename can be configured by calling
2251 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2253 Fix bug regarding multiple calls to ZOOM_connection_connect.
2255 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2257 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2258 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2260 ZOOM now allows inspection of X509 peer certificate for verification.
2261 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2263 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2264 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2265 as "modular" but it simplifies things.
2267 Added cs_get_peer_certificate to that returns peer X509 PEM.
2269 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2270 NULL if SSL is unavailable.
2272 Documentation about MARC decoding tools.
2274 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2276 --- 2.0.19 2004/03/30
2278 Rename CHANGELOG to NEWS to follow GNU style packing.
2280 Fix bug with missing initialization of member in init_diagnostics.
2281 This bug affects threaded version of GFS server.
2283 --- 2.0.18 2004/03/20
2285 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2288 Ensure zlib.dll is packed with Windows install.
2290 --- 2.0.17 2004/03/17
2292 Fix encoding of xsd:string to use text instead of CDATA.
2294 Fix endless loop in CQL parser with unbalanced ".
2296 Use a more compact way to store MARC-8 conversion tables.
2298 --- 2.0.16 2004/03/16 Debian only
2300 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2303 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2308 --- 2.0.15 2004/03/01
2310 Another fix for decoding of XML packed records.
2312 --- 2.0.14 2004/02/25
2314 Fixes for Chunked encoding. White space not ignored after length spec.
2316 Update NS and use default NS for SRW diagnostic elements.
2318 --- 2.0.13 2004/02/23
2320 Implement ZOOM_resultset_cache_reset which resets record cache.
2322 Implement ZOOM_resultset_sort which sorts a result set.
2324 Implement chunked HTTP transfer.
2326 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2328 --- 2.0.12 2004/02/16
2330 Added member 'schema' to bend_explain_rr structure so that backend
2331 can specify explain record identifier. Defaults to Zeerex 2.0.
2333 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2335 --- 2.0.11 2004/02/16
2337 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2340 Added init command for yaz-client which sends "extra" init request.
2342 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2343 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2345 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2347 Make ZOOM error code for "invalid query".
2349 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2351 --- 2.0.10 2004/02/05
2353 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2356 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2358 Added option -p <file> to make Generic Frontend Server to write PID file.
2360 Added option -D to put Generic Frontend Server in background on its own.
2362 Make ZOOM C recognize option "password". If unset, "pass" is used
2363 (for backwards compatibility).
2365 Fixed a bug in Generic Frontend Server that could make it crash if a
2366 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2369 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2370 Must be issued before open, in order to be in effect.
2372 --- 2.0.9-6 2004/01/12 Debian/Windows
2374 Make the SRU server more picky WRT unknown params, etc.
2376 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2378 New YAZ client command, options, that sets Z39.50 options.
2380 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2381 options from a string of tokens (one token for each option bit).
2383 Update SRW diagnostic code messages.
2385 --- 2.0.9-5 2004/01/07 Debian/Windows
2387 Handle user defined stylesheet for SRW/SRU.
2389 --- 2.0.9-4 2004/01/06 Debian/Windows
2391 Fix bug in decoding of Content-Length.
2393 --- 2.0.9-3 2004/01/06 Debian/Windows
2395 Fix a bug with decoding of XML packed records.
2397 --- 2.0.9-2 2004/01/05 Debian only
2399 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2401 Fix bug in SRW/SRU diagnostics decoding.
2403 --- 2.0.9 2004/01/05
2405 Fixed bug in Generic Frontend Server which could drop records exceeding
2406 preferred message size. Reported and fixed by Irina Dijour.
2408 Fixed calculation of package size for structured records in Generic
2409 Frontend Server. Reported and fixed by Irina Dijour.
2411 Fixed namespace for SRW/SRU diagnostics.
2413 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2415 --- 2.0.8 2003/12/22
2417 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2418 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2421 CQL changes to reflect recent changes to the specification:
2422 * Documentation talks about context sets instead of index sets.
2423 * Documentation talks about indexes instead of qualifiers.
2424 * The CQL-to-PQF transformer's configuration file now uses
2425 "index.set.name = <attributes>" instead of the old form
2426 "qualifier.set.name = <attributes>". (Both forms are still
2427 understood but the latter is deprecated.)
2428 * CQL terms with no explicit index specified are now interpreted as
2429 cql.serverChoice instead of srw.serverChoice (which of course
2430 behaves exactly the same.)
2432 --- 2.0.7 2003/12/16
2434 MARC conversion can now generate ISO2709 output in another
2435 character set. yaz-marcdump uses this facility if you invoke it
2438 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2439 functions from there can be used from C++.
2441 --- 2.0.6 2003/12/04
2443 Frontend server now transfers memory from decoded packages to stream
2446 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2447 references to show up.
2449 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2450 the ZOOM Abstract API. The older names for the same options are still
2451 also supported for the benefit of old applications.
2453 ZOOM-C supports "implementationId" and "implementationVersion" options
2454 to go along with "implementationName". These allow the user code to
2455 specify identification strings to be sent to servers.
2456 Add OID for the new ExtLite attribute set.
2458 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2459 as requested/supplid by Ere Maijala <ere@atp.fi>
2461 For generic frontend server, reverse the order of
2462 "toolkit-supplied / application-supplied" strings sent as implementationId,
2463 Name and Version. Also, remove the spaces around the slash. This brings
2464 the GFS in line with the behaviour of ZOOM-C on the client side.
2466 Add function ZOOM_scanset_display_term.
2468 yaz-client shows scan displayTerm if present.
2470 Utility yaz-iconv is now installed by default along with the man page
2473 Extend configure check for OpenSSL to use pkg-config where available (such
2476 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2477 server to specify uid/gid/mask for socket using the format
2478 unix:[user=uid,][group=gid,][umask=mask,]file=path
2479 If file= is omitted the existing format is assumed, e.g.
2481 in which case the mask is 0666 (rw for everybody).
2483 Major restructure of YAZ source. All source in libyaz is in src directory.
2484 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2485 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2487 Added man page for utility yaz-marcdump (used to be called marcdump).
2488 yaz-marcdump is installed by 'make install'.
2490 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2491 of incoming package failed.
2493 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2495 Change prototype of odr_perror: add const to message string.
2497 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2499 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2500 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2501 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2502 DNS lookup. There should not be any compatibility problems with this
2503 assuming that blocking=1 or 0 is used.
2505 Fix bad reference in UNIX comstack in function cs_addrstr.
2507 Fix for compilation on AIX.
2509 The generic front-end server (server/seshigh.c) now supports returning
2510 Init diagnostics to the client in User-information-field, in
2511 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2514 --- 2.0.4 2003/09/04
2516 Allow any CQL relation (not just all,any,exact,scr).
2518 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2519 that features the same UI.
2521 Implemented command update0 in YAZ client which is equivalent to
2522 update but uses old of Ext Update ASN.1.
2524 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2525 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2526 Previously no OID was used for this info.
2528 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2529 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2530 returns 'malformed search term' otherwise.
2532 SortResponse member resultCount now set to NULL in sort handler of
2535 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2538 Add three new utility functions for translating OIDs between various
2539 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2540 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2541 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2542 char *oid_to_dotstring(const int *oid, char *oidbuf);
2543 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2545 Reverted modifications for ES Update definition for z_IU0Update
2546 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2547 is back to YAZ 2.0.2.
2549 String value attributes for CCL parser.
2551 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2552 which their FirstSearch server returns in Init responses, sometimes
2553 carrying useful diagnostic information when Init fails. This has the
2554 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2555 "z39.50/oclcui.asn", where its definition is somewhat different from
2556 what OCLC document on their web-site, as required to interoperate with
2559 Support for anonymous authentication in yaz-client. Use the command
2562 * Fix the OID of the Index Data-local "admin" Extended Service from
2563 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2564 the 1000, which indicates a locally-defined OID, was a mistake.
2566 --- 2.0.3 2003/06/20
2568 Fix CCL directive @case handling so that it affects string match for
2569 both CCL keywords and qualifiers.
2571 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2572 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2573 Decoder has been updated with ASN.1 changes as listed in
2574 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2575 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2576 z_IUUpdate, remains unchanged.
2578 ZOOM_record_get may now return a record in a specific character set.
2579 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2580 "from" is the character set of record as returned by target. "to" is
2581 the character set to be returned. If omitted, "to" is UTF-8.
2583 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2585 New ODR utility, odr_getelement, which returns name of element for
2586 which encoding/decoding failed.
2588 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2589 in cases where a required element was omitted.
2591 Bug fix: some MARC8 sequences were not converted.
2593 New ZOOM option "step" which specifies number of records to be
2594 retrieved in one chunk. Used in conjunction with "start" and "count".
2596 SRW support for yaz-client. Use scheme http: to use it, e.g.
2599 yaz-client no longer does (un)intelligent character set conversions
2600 by default. Can be enabled with charset and marc_charset commands.
2602 xmalloc trace fix for 64-bit systems such as DEC alpha.
2604 Solaris 2.6 compile fix.
2606 New function, cql_strerror() translates SRW error codes, as returned
2607 by cql_transform_error(), into human-readable English strings. Used
2608 in yaz-client diagnostics when appropriate.
2610 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2611 converts it into a type-1 query which is sent to the server. This
2612 makes CQL available for use with all Z-servers, as opposed to the tiny
2613 minority that can handle CQL queries themselves.
2615 --- 2.0.2 2003/04/28
2617 New Debian package layout similar to the Redhat Package layout.
2619 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2620 and search result respectively.
2622 --- 2.0.1 2003/04/25
2624 Redhat package is now several packages: libyaz (runtime libraries),
2625 libyaz-devel (development and documentation, and yaz (utility programs).
2626 Package spec file by Morten Bogeskov.
2628 New member 'schema' in struct bend_fetch_rr which the name of requested
2629 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2630 handler MAY set this to reflect the schema of the returned record.
2632 New member 'display_term' in struct scan_entry. GFS now sets member entries
2633 and allocates scan entries to be filled by user scan handler. In previous
2634 version, entries member was allocated by the scan handler. That still works,
2635 but the GFS will ignore member display_term - assuming it was NOT set by
2636 the handler. The fact that the GFS now allocates the entries both allows
2637 for new members and makes a scan handler easier to write.
2639 Fix CQL lex buffer overflow.
2641 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2642 SRU default recordPacking is string.
2644 SRU protocol support for frontend server.
2646 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2648 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2650 Added scan for the ZOOM shell (zoomsh).
2654 * String Identifers for Schemas (Amendment 5).
2655 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2656 Old definition for schema
2657 Odr_oid *schema; /* OPT */
2662 Z_InternationalString *uri;
2663 #define Z_Schema_oid 1
2664 #define Z_Schema_uri 2
2667 * resultCount parameter to Sort Response (Amendment 1).
2668 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2670 Support for SRW 1.0 over HTTP. This is an optional feature and
2671 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2674 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2675 on the same port. SRW SearchRetrieveRequests are mapped
2676 to bend_init,bend_search,bend_fetch,bend_close.
2678 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2680 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2681 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2683 ZOOM connections are SRW based if schem http is used for hostname
2684 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2685 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2687 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2688 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2689 distance=n, order=true/false, relation=le, prox unit=word. If
2690 n is omitted, distance 1 is used.
2692 Fixed problem with C compiler include path in wrong order.
2694 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2695 on Solaris. Patch from Ko van der Sloot.
2697 New MARC decode API. All new functions operate on a yaz_marc_t
2698 handle. The most important new functions are: yaz_marc_create,
2699 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2700 decode and destroy respectively. Decoder can produce formats
2701 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2702 include/yaz/marcdisp.h.
2704 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2705 to UTF-8, UCS-32, wchar_t or Latin-1.
2707 * Prototypes for yaz_iconv_-functions moved to separate header
2708 include/yaz/yaz-iconv.h.
2710 Make a few private functions 'static' in unix.c. This prevents
2711 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2713 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2714 are set when Init Response is received.
2716 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2717 but returns diagnostic set as well.
2719 New function yaz_strerror which is a portable wrapper for
2720 strerror/strerror_r/GetLastMessage.
2722 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2723 is returned for MARC. If type is "oai", then OAI MARC is returned.
2725 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2728 --- 1.9.2 2002/11/26
2730 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2732 Fix bad race conditions on SIGTERM and terminate gracefully in
2735 Move retrieval (data1) module to Zebra since nobody seems to be
2738 Add GRS-1 render for ZOOM using same format as yaz-client.
2740 --- 1.9.1 2002/10/05
2742 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2744 Fix broken ESpec handling in data1 module.
2746 SGML reader parses comments and makes them part of the data1 tree.
2748 Added several type casts so that YAZ compiles as C++ code.
2750 ZOOM didn't handle PDU encoding failures properly.
2752 Added more Bib-1 diagnostics (approved extensions).
2754 GNU configure: better check for iconv.
2756 More portable use of accept, getpeername. Check for socklen_t. Use
2757 int/size_t if socklen_t is not defined.
2761 PQF parser rejects bad queries - including those with extra
2762 characters in them. PQF parser used to silently ignore that.
2763 Cleaner API for PQF added, which allows you to get detailed
2764 error information for bad queries (see yaz/pquery.h).
2766 Fixed bug in ZOOM_record_get for type "database".
2768 Implemented mini iconv library supporting conversions between
2769 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2771 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2773 --- 1.8.9 2002/08/20
2775 Fixed ZOOM C record cache so that preferredRecordSyntax and
2776 elementSetName is used to check for already fetched records.
2778 --- 1.8.8 2002/08/02
2780 Added three members in bend_initrequest structure to facilitate
2781 character set negotiation.
2783 Fixed a bug in frontend server that could cause indefinite
2784 loops under rare conditions.
2786 Revised character set utilities (charneg.h) so that encoding
2787 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2789 For PQF, directive @term <type> sets term type for Scan/Search.
2790 Here <type> is general, string, numeric, null. The term type
2791 is inherited - just like @attr.
2793 New call odr_set_charset that sets character set conversion for
2794 international-strings on a ODR stream. Prototype is:
2795 int odr_set_charset(ODR o, const char *to, const char *from);
2796 The InternationalString is still represented as C string in YAZ
2797 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2798 won't). On the protocol level, you can use any encoding.
2800 Support for UNIX sockets in ZOOM.
2802 Solaris recv sometimes returns errno == ENOENT. It is treated as
2803 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2805 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2806 both client and server. Code by Morten Bogeskov.
2808 --- 1.8.7 2002/05/22
2810 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2811 that they can be used directly from Visual Basic. You must recompile
2812 your windows APP if you're using ZOOM.
2814 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2815 Commands "lang" and "charset" sets language and character set respectively.
2816 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2817 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2819 Attributes from multiple CCL fields may be OR'ed rather than merged
2820 using directive "@field or". Fields are still merged by default -
2821 equivalent to "@field merge".
2823 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2826 Fixed bug in zget for parameter ExtendedServicesResponse.
2830 --- 1.8.6 2002/03/25
2832 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2834 Client displays USR.1:SearchResult-1 (hits per term).
2836 Additional Search Info for search in Generic Frontend Server.
2838 Fixed CCL parsing of "field=s".
2840 WIN32 installer - using the excellent NSIS software from nullsoft.
2842 Fixed CCL parsing of "field = - <number>".
2844 Added function yaz_marc_decode that decodes MARC for line mode
2845 display or XML (similar to that used by JZKit).
2847 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2848 Z39.50. But ISO/ILL was, however.
2850 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2851 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2853 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2854 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2856 --- 1.8.5 2002/02/03
2858 New YAZ client features: Command completion and new commands:
2859 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2860 Code provided by Jacob Poulsen.
2862 New call oid_trav, that visits all registered OIDs via callback.
2864 Function ZOOM_record_get now returns const char pointer rather than
2865 void pointer. It saves a lot of type casts.
2867 For YAZ client, command "auth" now allows you to set authentication
2868 in IdPass style. It is enabled when three tokens are given - order
2869 is user, group and password.
2871 Fix memory leaks in MARC record handling for ZOOM.
2873 New option for YAZ client, -k <kilobytes> that sets
2874 maximum record size. Similar to -k option for generic frontend
2875 server and yaz-ztest.
2877 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2879 Prefix query parser reports "fail" when bad attribute set is given.
2881 Fix in MARC decoder. Proximity logging. Fix for attribute set
2882 in scan handler for server. Patches by Shigeru Ishida.
2884 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2887 Configure option --with-openssl=<dir> now works when a directory is
2888 specified. Patch provided by Morten Bogeskov.
2890 New option for YAZ client, -u <auth>, that sets authentication.
2892 ZOOM fix: error information was sometimes "missing", since error
2893 was cleared/reset too when it shouldn't.
2895 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2897 --- 1.8.4 2002/01/04
2899 Scan for ZOOM API. New object ZOOM_scanset. New functions
2900 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2901 ZOOM_scanset_destroy.
2903 New ZOOM function, ZOOM_connection_last_event, that returns type
2904 of last event (such as "receive data", "send data", "apdu received",
2907 New ZOOM option, schema, that specifies schema for retrieval.
2909 New CCL feature. Qualifiers can be aliases for one or more
2910 other qualifiers (if more than one is given, OR is used).
2912 ZOOM uses named result sets if target supports it.
2914 Two new YAZ client commands: . (dot, which sources a script of YAZ
2915 client commands), and ! (to execute shell command.). Implemented
2918 Working on Debian packages.
2920 --- 1.8.3 2001/11/19
2922 YAZ client enables named result sets only if target supports it.
2924 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2926 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2927 with key="host" to get same result.
2929 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2930 Function Z3950_resultset_record(s) returns references to records
2931 "owned" by resultset. To become owner use Z3950_record_clone.
2933 Function z_ext_record handles Extended Services. Thanks to
2936 --- 1.8.2 2001/11/12
2938 CCL Parser fix: ignore token comma when dealing with and-lists.
2940 Documentation updates for COMSTACK.
2942 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2943 Changed prototype Z3950_records. For some functions, int parameters
2944 were changed to size_t.
2946 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2949 New MARC decode/display function, marc_display_exl, which properly rejects
2950 non-ISO2709 records. YAZ client uses it.
2952 --- 1.8.1 2001/10/29
2954 Fix bug: local attribute set wasn't set correctly in PQF strings.
2958 * Old Z39.50 codecs no longer supported.
2960 Added ZOOM C binding. See http://zoom.z3950.org/
2962 Renamed states for COMSTACKs to avoid confusion with events.
2964 Implemented cs_look and proper cs_rcvconnect.
2966 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2968 Configure detects POSIX threads on OpenBSD.
2970 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2971 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2973 When error is returned from present handler, non-surrogate diagnostic
2974 is returned in present response (and fetch handler is no longer called).
2976 * Minor adjustments to pquery parser (PQF). Token characters may be
2977 escaped by using backslash (C-style).
2979 PQF parser allows string attribute values to be specified. For @attr,
2980 non-numeric characters after the equal-sign are treated as strings
2981 (e.g. @attr 9=title).
2983 CCL trunction character may be defined (@truncation in file)
2985 * function zget_ExtendedServicesRequest sets waitAction to
2986 waitIfPossible (was wait).
2988 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2991 CCL operator names may be set in field definition files (CCL_bibset).
2992 See ccl/bib1 for an example.
2994 Fixes in ASN.1 compiler for C++ compatibility.
2996 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2997 and "op_or" to avoid conflict with C++.
2999 Fixed problem with GNU readline detection on Redhat 7.0.
3001 Added step-size for Scan backend handler.
3003 Fixed bug that made the frontend server crash when no attribute
3004 set was specified for scan.
3006 Front-end server automatically switches to original working directory
3007 when installed as an NT service. Previously -w had to be specified to
3010 Added extended attributes for retrieval module (data1), so that data1
3011 records carry d1_readXML/SGML attributes. d1_read also supports
3012 null-data rules ( <tag/>)
3014 On UNIX when POSIX threads are available, a separate library libyazthread
3015 is created. Programmers should link with that library and the yaz library
3016 when using threads. The reason for the split was that some applications
3017 on Linux, such as Apache, doesn't work well when using shared objects that
3020 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3021 (or any frontend server) in SSL mode by specifying ssl: followed by
3022 address. Only tested on UNIX.
3024 Added feature for CCL module. Virtual structure s=al or s=ol generates
3025 and-list and or-list respectively instead of phrase search.
3029 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3030 log_mask_str. This was done to avoid name conflicts with other libraries
3031 (such as other PHP extensions).
3033 Added raw OID member for preferred record syntax (request_format_raw)
3034 and returned record syntax (output_format_raw) for backend fetch method.
3036 Config file yaz-config now accepts options so that it returns specific
3037 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3039 Shared library support for UNIX using GNU libtool.
3041 * Modified backend interface. Request/Response struct's replaced by
3042 one read/write C struct. For example bend_fetchrequest and
3043 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3044 Every handler - even search has to be registered in bend_init
3045 handler. This means that the YAZ library no longer refers to
3046 external functions and it makes it possible to make the whole
3047 thing a single DLL/SO.
3049 Added Segment handler for backend server.
3051 Added Zmbol/Zebra administrative functions to YAZ client.
3053 Threaded frontend server on UNIX (when POSIX Threads are available).
3054 Starting the server with option -T enables multi-threading.
3058 Added configure option --enable-comp/disable-comp to control use
3059 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3060 located in sub directory asn.
3062 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3063 in ${exec_prefix}/bin along with the other programs yaz-client and
3066 GNU automake used to maintain makefiles.
3068 Added several OID's.
3070 Changed retrieval module so that we can load records with no abstract
3071 syntax defined. Tagpaths in these records are fully composed of string
3074 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3078 On UNIX, the generated makefile now supports a proper 'make install'.
3079 The prefix can be set via GNU configure to set the install location
3080 (default is /usr/local).
3082 * YAZ programs client and ztest were renamed to yaz-client and
3083 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3084 locations, such as /usr/bin,/usr/local/bin,etc.
3086 * YAZ Header files were moved from include to include/yaz. YAZ Header
3087 files are referred to as include <yaz/log.h> rather than <log.h>.
3088 The YAZ include path (-I ..) is therefore the same as before. Programmers
3089 should update their #include statements or use -Ipath/include/yaz
3090 instead. The main motivation for doing this change is that YAZ header files
3091 can be installed in "standard" locations /usr/include,/usr/local/include
3092 without introducing conflicts, since ALL YAZ header files are stored
3093 in subdirectory yaz (under /usr/include for example).
3095 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3096 rather than project/workspace files. We switched because project files
3097 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3100 Changed name of logging function, logf, to yaz_log, to prevent name
3101 clash with some math-log functions. The YAZ header log.h defines logf
3102 to yaz_log (#define) so there should be no incompatibilities by this
3105 Added bend_start/bend_stop handlers for server. These handler are
3106 called on start/stop of server. For windows they are called whenever
3107 a service is started/stopped.
3109 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3110 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3111 in util/yc.tcl. The auto-generated C code structures are, in a few
3112 cases, incompatible with the old decoders. There are differences in the
3113 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3114 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3115 The preprocessor variable ASN_COMPILED is defined when the compiled
3116 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3117 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3118 wish to use the old encoders/decoders you can specify --disable-yc
3121 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3122 version so that it supports both new - and old version of DB Update
3124 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3125 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3126 change. The name parameter can be set to 0 in which no name is specified
3127 for the construction. The macros odr_implicit and odr_explicit sets name
3128 parameter to zero for the construction involved. New macros
3129 odr_implicit_tag and odr_explicit_tag are similar to the others,
3130 except that a name parameter is added. For programmers' that don't use
3131 ODR they probably only need to change the call to z_APDU and z_External.
3133 Added access control facility by interfacing the TCP wrapper library.
3134 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3135 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3136 name of the daemon and enables the access control as specified in
3137 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3139 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3140 den Dool <H.M.vdnDool@kub.nl>.
3142 Added reference ID parameter to most functions in server API - refer
3143 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3145 Changed name of ccl library to libccl.a (was ccl.a).
3147 Fixed bug in decoder for Explain (Category TargetInfo).
3149 Added support for GNU readline in client. Thanks to Jacob Poulsen
3150 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3152 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3153 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3154 IMPLEMENTATION! This change was made to the development version before
3155 the ZIG decided to retract the amendment. If any users MUST be
3156 compatible with the original Update definition, PLEASE CONTACT US, and
3157 we will include a separate definition corresponding to the old Update
3158 ES. Note that because of the change to the ASN.1 of the
3159 TaskPackageRecordStructure we cannot define a single structure that
3160 will support both versions.
3162 * Added const modifier to buffer parameter for some ODR/BER encoding
3163 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3164 completeWAIS, odr_dumpBER.
3166 Fixed bug in client.c which caused a crash when a scanResponse didn't
3167 contain positionOfTerm.
3169 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3170 * will cause an error in a client if a non-YAZ target sends both a
3171 * list of Scan entries and non-surrogate diagnostics.
3173 Retrieval module enhancements. Tag sets may be typed in the reference
3174 to it. From the .abs-file the "tagset" directive takes a third optional
3175 integer type for the tag set referenced. From a .tag-file the "include"
3176 directive takes a third optional type as well. The old "type" directive
3177 in the tag set itself is still recognized but acts as the default type
3180 Backend interface change. Individual Scan terms returned from bend_scan
3181 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3182 in include/backend.h.
3184 Retrieval module enhancements. Multiple tag sets and attribute sets may
3185 be specified in abstract syntax specs. Revised the error/warning for
3186 logging messages reported by the retrieval module when reading the
3189 Object Identifier system (oid_..) changed. The API is backwards
3190 compatible but the oid-routines now allocates new OID's when needed.
3191 Raw OID's may be specified in oid_getvalbyname.
3193 YAZ now uses GNU configure to generate Makefile(s).
3195 * Minor changes in some of the member names of DeleteResultSetRequest and
3196 DeleteResultSetResponse. See include/proto.h.
3198 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3199 and added member 'languages' in TargetInfo (which was missing).
3201 Changed the way attribute sets are handled in the retrieval
3202 module. These are now cached, just like the abstract syntaxes
3205 Changed YAZ so that it links with compiled ASN.1.
3207 Added Explain-schema definitions and mapping routines. The following
3208 Explain categories have been implemented: AttributeDetails,
3209 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3211 Fixed minor bug in Windows version of Server Library.
3213 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3215 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3217 Added EXTERNAL: UNIverse Resource Report (non-standard).
3219 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3220 ENUMERATED and SET OF.
3222 * Added 'const' to some of the char pointer arguments for the
3223 functions, data1_read_node, data1_getelementbytagname,
3224 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3227 Fixed bug in data1_insert_taggeddata - the last_child member of
3228 parent wasn't initialised.
3230 * Changed data1_read_record and data1_read_node so that the supplied
3231 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3232 doesn't refer to any parts of the "SGML"-buffer.
3234 Fixed bug in server library (Windows version of statserv_remove).
3236 * Changed code so that it compiles as C++. The type definition
3237 of Odr_fun which is a member of Odr_arm was changed. The result is,
3238 that an explicit typecast is needed for the fun pointer when
3239 using Odr_arm - as in:
3240 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3242 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3244 Implemented the new structured date and time definition as approved
3245 by the ZIG. Added schemaId element to the specificTag in Espec-1
3246 (also approved at the last ZIG). Thanks to RVDM.
3248 Added some Object identifiers (RVDM).
3250 Changed the Update Extended Service (RVDM).
3252 Added command "refid" to client which specifies referenceId for
3253 the following requests.
3255 Implemented extended service handling for server. See ztest.c
3256 for an example as well as backend.h. New handlers are registerd
3257 in the Init handler.
3259 * Changed interface for sort in server.
3261 Added new members to statserv_options_block. It allows a server
3262 to read options from another source than just the command line. Thanks
3263 to Charles Woodfield.
3265 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3266 renamed to zboolean. Some C++ compilers complained about the name.
3268 Minor changes to gils.abs. Added index 's' (sort) on title
3269 and date/time-last-modified.
3271 --- 1.4pl2 1998/1/30
3273 Fixed bug in server library regarding inetd mode (-i). This bug
3274 was introduced by release 1.4.
3276 --- 1.4pl1 1998/1/29
3278 Added sort facility in client and backend server interface.
3280 Fixed problem with dependencies in Makefile(s).
3282 Fixed bugs for encoders/decoders of extended services and
3285 Implemented sub-tree feature for schemas. Sub-trees are
3286 referenced in *.abs-files. See explain.abs for an example
3287 of the use of this feature.
3289 Modified bib1.att; local attributes for ANY didn't include
3290 ANY itself (only affects use of the retrieval module).
3292 Fixed bug in plain SGML reader in function data1_read_node:
3293 tags with prefix "var" was incorrectly interpreted as variants.
3295 Added feature "sub-schemas" to enable references to - and definitions
3296 of - group of elements.
3298 * Removed member parent from type data1_element (in data1.h).
3300 Implemented function odr_nullval() that returns the value of
3303 * Removed member num_children from data1_node (in data1.h).
3305 Made NT service interface part of the server library. The
3306 function statserv_main uses the NT service when required and
3307 calls the statserv_start / statserv_close routines.
3309 Routine zget_SearchRequest and zget_PresentRequest fills
3310 resultSetName/Id member with "default" instead of "Default".
3312 Fixed memory leak in server. Request queue member wasn't freed.
3314 Fixed nmem_exit so that memory is freed.
3318 Revised the CCL parser utility to be thread safe.
3320 Added function, oid_ent_to_oid, to replace the function
3321 oid_getoidbyent, which is not thread safe.
3323 * Added nmem_init and nmem_exit to initialize and release
3324 NMEM resources. Function nmem_init should be called once in the
3325 initial thread before NMEM/ODR is used. statserv.c and client.c
3326 have been changed accordingly. The change was necessary to make
3327 NMEM thread safe. The NMEM memory pool is shared amongst threads
3328 in a process. Unix-based applications will still work fine without
3331 Added NT Services interface for the the Z39.50 (statserv) Server.
3332 Refer to the ztest.c source on the usage.
3334 Windows 95/NT port using MSVC5.0. Project files are included in the
3337 * Defined new 'global' handle for the retrieval (data1) system. The
3338 new handled, data1_handle, describes the state of the data1 system.
3339 This handle is passed as first argument to virtually all
3340 data1 related routines. The functions data1_create and data1_destroy
3341 creates and destroys a data1 handle respectively.
3343 Added ODR encode stream member to all backend request structures
3344 init, search, scan etc. This stream should be used to allocate all
3345 memory used for the response when thread safe operation is needed.
3347 Changed the comstack utility, cs_addstr, to be thread safe. The
3348 returned hostname string returned by the function is now part the
3351 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3352 function. The cs_straddr takes a COMSTACK handle as argument, so this
3353 function must be used after cs_create and before bind/connect.
3354 This function is thread safe.
3356 Moved test server to 'ztest' directory - generic server code still
3357 in 'server' directory.
3359 Made prefix query (pquery.c) utility thread safe.
3361 Added new function modifier YAZ_EXPORT to 'export' public DLL
3362 functions when using windows (see include/yconfig.h).
3364 Added definitions to the OID database (util/oid.c) (RVDM).
3366 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3368 Added call to ccl_rpn_delete in client program.
3370 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3371 release of RPN structure.
3373 Added support for C++, headers uses extern "C" for public definitions.
3374 With input from RVDM.
3376 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3377 Thanks to Ronald van der Meer (RVDM).
3379 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3381 Added support for private extensions to the OID database
3382 (oid_setprivateoids()). Thanks to RVDM.
3384 Added optional, physical ANY (key replication)
3386 Fixed null-reference problem in GRS-1 output filter.
3388 Proximity operator added to Prefix Query Format (PQF).
3390 In test client command "base" accepts multiple databases.
3392 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3396 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3398 Smallish bug-fixes in the new encoders/decoders (explain).
3400 Bug fixed in DeleteRequest.
3402 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3404 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3406 Added SOIF syntax (using private OID for now) to retrieval module and client.
3408 Added Update extended service.
3410 Added SearchResult-1 additional info structure.
3412 Added optional CCL (ISO8777) interpreter as separate module. Available
3415 --- 1.2 1996/6/10 (1st anniversary release)
3417 Added Summary record syntax. Lightly tested.
3419 Added OPAC record syntax. Untested.
3421 Added ResourceReport service encoders/decoders. Untested.
3423 Fixed bug in z_Unit - wrong tagging on unitSystem.
3425 Fixed bug in the DiagRecs decoder.
3427 Added options for max PDU size and session timeout to frontend-server.
3429 Added documentation of query-language parsers and other supporting utilities.
3431 [frontend-server] Added Attribute set to the bend_scanrequest API.
3433 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3434 surrogate diagnostics were generated.
3436 [retrieval] Allow multiple local values for attribute.
3438 [retrieval] Allow multiple attributes per element in .abs files. index type.
3440 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3442 --- 1.1pl2 1996/4/10
3444 Minor changes, mostly specific to Zebra's requirements (retrieval)
3448 Repaired bug in frontend server when running multiple listening
3449 endpoints in dynamic mode.
3451 z_External() now won't break if a known, ASN.1 value comes encapsulated
3452 in an octet-string. The value will pass through unmodified in an Odr_oct.
3454 Added a bit of code to the demo client to decode & display
3455 ASN.1-structured records represented in the octet-aligned branch of
3456 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3458 Added z_ext_getentbyref() to the ASN module. Doc updated.
3460 * Completed the SCAN definition in the ASN module. This may break SCAN
3461 code based on older YAZ-versions at compile-time. The fix is easy -
3464 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3465 under the SCAN definition. Remember to initialize this, server-people.
3467 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3468 that this does not extend to ODR and ASN.
3470 Comstack allows insertion of established socket (primarily for
3471 inetd-operation of servers). Doc updated.
3473 Front-end server can now start from the inetd in TCP mode. Doc
3476 --- 1.0pl4 1996/1/24
3480 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3481 the rank and record number.
3483 Adjustments to the frontend server.
3485 Fixed diagnostic BER dumper. It ignored the file argument.
3489 Various changes to retrieval module.
3491 Changed the union discriminators of the protocol files from enums to
3492 ints paired with #defines.
3494 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3497 *Changed operator in the RPN structure to 'roperator', again to avoid a
3500 Fixed problems in Explain decoders/encoders.
3502 --- 1.0pl2 1995/12/6
3504 Memory bug in log module fixed.
3506 --- 1.0pl1 1995/12/5
3508 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3510 Bug in Explain DatabaseInfo module fixed.
3512 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3516 The shift to v1.0 signals that we now consider the *core* functionality
3517 of YAZ reasonably stable (the core being more or less equivalent to
3518 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3519 tested (Explain not at all - though that will happen soonish).
3521 Minor changes to code to support Windows port.
3523 Various minor changes after we're getting to use GRS-1 & co. more.
3525 Added Espec-1 format.
3527 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3528 of the protocol and it cannot be selected when encoding (maps into 'string'
3529 when decoding). Needed to talk to some servers.
3531 Demo client can request simple element set names.
3533 Added Diagnostic Format encoders/decoders.
3535 Added simple Close handling to frontend server (no hooks for resource
3536 reporting yet), and demonstration client.
3538 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3540 --- 1.0b3 1995/08/24
3542 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3543 handled incorrectly when records were requested in the searchResponse. This
3544 will only affect you if you use the frontend-server.
3546 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3547 Test-client will ask for and print GRS1. Ztest will return dummy records
3550 Added Explain encoders/decoders to the service-level API. Untested.
3552 Added Extended Services: Item Order encoders and decoders to the Service-
3553 level API. Untested. We could use a recent copy of the pertinent bits
3554 of the ILL protocol to add those bits.
3556 Added diagnostic format 1 encoders/decoders to the service-level API.
3559 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3560 odr_cons.c, which causes a more correct output.
3562 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3563 was always set to 0 when no records were requested in the searchRequest.
3565 * Added better external-handling. This shouldn't harm old code that
3566 *encodes* externals. It can break code that looks for a
3567 'single-ASN1-type' representation, since those types that are known
3568 are now decoded immediately. Look at the SUTRS sample code in
3569 seshigh.c and client.c. Documentation updated.
3571 Handling of structured records in bend_fetchresponse. Length -1 marks
3572 structured record, type is deduced from format field.
3574 --- 1.0b2 1995/06/27
3575 Fairly quick maintenance release to add SUTRS support.
3577 Fixed handling of SUTRS records in the demonstration client.
3579 * Added format field to the bend_fetchrequest and bend_fetchresponce
3580 structures of the backend API (frontend server). When the record is
3581 returned, the value of the format field is mapped to an OID. The
3582 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3583 of the record. The special value VAL_NONE in the bend_request means
3584 that no specific format was requested by the client. Documentation
3585 updated accordingly. Test server (ztest) will return a fixed dummy
3586 SUTRS record if your client requests SUTRS.
3588 Documentation updated accordingly.
3590 You can now set external libraries and RANLIB support in the top-level
3594 First public release.
