3 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
4 can read and write this format. For record format JSON, yaz-ztest returns
7 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
8 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
12 Improve error reporting for ICU chains YAZ-707
13 Report config element+rule when ICU status is "failure".
15 ZOOM: stop fetching if present response has no records YAZ-710
16 Some targets return less records than their hit count would suggest.
17 This prevents ZOOM from continuing to fetch records if any present
18 response has 0 records in the response.
20 Ensure that GFS calls exit if any listener fails YAZ-710
21 Before, if XML config was in use, it would start the default
26 yaz-ztest: -V shows version (like yaz-client -V)
28 New iconv encoding: danmarc YAZ-692
30 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
32 daemon: only wait for immediate child rather than all children. YAZ-704
34 yaz-client: fix setting of SRU record schema. If scheme was unset, it
35 could lead to invalid memory reference.
39 yaz-ztest returns schema for MARCXML test records. SRU require that
40 recordSchema for records.
42 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
43 instead of non-surrogate diagnostic. This is a per-record failure.
45 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
46 may refer to multiple listeners now. Attribute listenref is a comma separated
49 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
50 option is given for GFS, the dirname of filename (for -f) is used
51 as prefix for options such as cql2rpn, ccl2rpn, etc.
53 Content-Type charset fixes YAZ-701 . Do not inspect charset in
54 Content-Type header for SOAP when decoding SRU. The payload (XML)
55 itself tells what encoding it is. In response, never supply encoding
56 in Content-Type. The response payload (XML) tells what it is (with no
57 encoding in XML it's UTF-8).
59 HTTP decoding: allow blanks in URL paths YAZ-700
63 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
64 and facets. Ensure recordData and recordSchema are always present in
65 record element, because they are required.
67 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
70 Simplify in a lot of places using odr_strdupn.
72 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
76 Increase various buffers in GFS's statserv_options_block
77 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
78 This change makes many type-casts redundant, and, thus simplifies code.
80 Remove last bits of WAIS support.
82 Remove member 'size' from Odr_oct.
84 Slim down the public part of 'struct odr'. Most elements are not part
85 of struct Odr_private.
87 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
88 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
89 In particular facets are supported in both client - and server side.
90 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
91 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
92 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
93 both request/response). This is what a search handler in the GFS
94 will see (regardless of whether operating in SRU mode or Z39.50).
96 Changes to the srw.h (SRU/Solr) definitions include:
97 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
98 (char*), which replace union query and query_type (int). This is because
99 SRU 2.0 supports a queryType parameter. This also means that, to carry
100 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
101 x-pquery=PQFstring (extention parameter). The extension parameter
103 - New element, packing, that has information about SRU
104 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
106 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
108 New element, packing, in Z_SRW_explainRequest.
110 New elements in Z_SRW_scanRequest, queryType and scanClause.
111 These replace query_type and scanClase untion. This is similar to what
114 --- 4.2.69 2013/10/01
116 GFS: log when closing down - at least SIGTERM YAZ-684
117 Also change formatting WRT PID logging a bit.
119 Improve display of MARC records with multi-byte subfield IDs YAZ-695
120 In some rare cases subfield identifiers are multi-byte characters.
121 This will try to deterime length of those and split accordingly.
122 This affects display in line mode as MARCXML/MarcXchange. The encoding
123 of ISO2709 is the same.
125 Change inp argument to const for yaz_read_UTF8_char.
127 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
129 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
131 Better check of marc leader info YAZ-691
132 Problem is that some systems generate MARCXML/MarcXchange with
133 funny headers. These will not work if encoded as ISO2709.
134 Some tests produce new output, due to updated warning messages
136 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
138 yaz-client: display MAB records YAZ-689.
139 Thanks for Heiko Jansen for this patch.
141 New utility z_get_HTTP_Response_server which allows both HTTP server name
142 and HTTP server URL to be given in response.
144 Debian: do not depend on obs tcl8.3.
146 Debian: do not depend on obs libicu36-dev.
148 --- 4.2.68 2013/09/23
150 GFS: pass additionalSearchInfo to search memeber search_input if
151 given. Otherwise pass otherInfo. Request for facets and other search
152 related things will be passed there in future versions of YAZ.
154 New ZOOM setting, authenticationMode, which allows authentication
155 paramters to be encoded in the URL rather than via HTTP Basic auth.
158 rpn2solr: fix nested AND/OR handling. YAZ-685
160 Add comparison routines for some Z-types, such as NamePlusRecord,
161 RPNQuery, Query, RecordComposition and OtherInformation.
163 --- 4.2.67 2013/09/19
165 Don't decode MAB as MARC. Just like we don't attempt to decode
166 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
168 CCL: allow quoted terms for date ranges. YAZ-681
170 Introduce ccl_parser_qual_search. This function makes old function
171 ccl_qual_search, from YAZ 2, available again.
173 Add yaz_facet_list_to_wrbuf. YAZ-683
175 --- 4.2.66 2013/09/11
177 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
178 schema was given for search. YAZ-675
180 Add Solr date range searches. YAZ-621
182 --- 4.2.65 2013/08/22
184 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
186 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
188 ISO2709/MARC parse most octet aligned records; not just those that
189 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
190 MARC parse more records instead of just dumping as is. YAZ-670
192 ZOOM: proper caching for variations of record schema. YAZ-671
194 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
196 --- 4.2.63 2013/07/17
200 --- 4.2.62 2013/07/11
202 New utility z_get_HTTP_Response_details - an extended version of
205 New utility yaz_url_get_error which returns error message of last
206 failed yaz_url_exec call.
208 yaz-url and url functions: allow max HTTP redirects to be controlled.
210 New functions yaz_file_glob2, yaz_xml_include_glob.
211 These functions takes a flags parameter, which, for now only controls
212 whether to fail inclusion of a non-existing file (without glob
213 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
215 --- 4.2.61 2013/06/20
217 For MARC XML parsing, allow record without leader. A fake/default leader
218 is inserted and a warning is tagged with the record.
220 ICU: fix leak in in icu_iter_get_org_info.
222 --- 4.2.60 2013/06/14
224 ICU: fix bug in icu_iter_get_org_info (un-init variable).
226 --- 4.2.59 2013/06/11
228 Implement z_HTTP_header_remove.
230 --- 4.2.58 2013/06/11
232 ICU: Disallow 0 ptrs for some ICU string utilities.
234 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
235 returns original tokens (before normalization).
237 CCL: avoid z39.58/regex truncation when not needed. Apply only the
238 conversion of those masks, when absolutely necessary.
240 CCL: configurable masking character - @mask. Default masking character
243 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
244 full response anyway, so a Transfer-Encoding header will obstruct the
247 --- 4.2.57 2013/05/15
249 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
250 picking a socket. Problem is that some systems has IPV6 support, but
251 we can't create sockets for them, so we pick AF_UNSPEC first.
253 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
254 use content_len to determine resulting Content-Length in HTTP response
255 and NOT Content-Length supplied in headers by user.
257 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
258 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
260 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
263 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
264 with big endian and unsigned char (by default).
266 --- 4.2.56 2013/04/26
268 Fix yaz-client connect (crash in 4.2.55).
270 --- 4.2.55 2013/04/26
272 Fix proxy/host problem for ZOOM that could occur if unix sockets
275 New Debian package libyaz4-dbg.
277 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
278 differently in tcpip_close.
280 --- 4.2.54 2013/04/17
282 Windows installer of YAZ includes YAZ4J as a component.
284 CQL: allow "extra terms" again, by default. Thus, the CQL parser
285 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
286 and earlier. CQL parser may operate in strict mode where queries
287 not conforming to the standard BNF are rejected (syntax error).
288 Whether the CQL parser operates in strict mode is controlled with
289 cql_parser_strict . Strict mode enabled with option -S for utilities
290 cql2pqf and cql2xcql .
292 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
294 --- 4.2.53 2013/04/10
296 New charset, MARC-8c, which is like MARC-8 but allows control characters
297 0x01 through 0x1F, except ESC to be passed through verbatim.
299 Fix a problem with duplicate sub field character in MARC output. Problem
300 happened only when output was MARC-8 encoded.
302 --- 4.2.52 2013/04/03
304 yaz-ztest: Use hash for fake hit count. Before, random number was used.
305 This is problematic for unit tests using yaz-ztest. This patch also makes
306 a hash for CQL queries. For RPN, any term with a leading digit will be
307 treated as pseudu hit count (to force any particular hit count by a client).
309 yaz-ztest: return unique MARC dummy records. Beyond record offset
310 24, the author surname is patched with offset to make all records
313 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
314 on system wide default (/proc/sys/net/ipv6/bindv6only).
315 @4 binds to IPV4 only. @6 binds to IPV6 only.
317 Update CQL API documentation a bit
319 CQL: don't accept extra terms for queries. Makes the CQL parser
320 stricly conformant to the standard.
322 --- 4.2.51 2013/02/12
324 GFS: scan handler gets extra_args from request and may return extra
325 response data . That's for SRU only.
327 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
329 --- 4.2.50 2013/01/30
331 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
333 OPACXML: sync spelling of availabilityDate in XML to that of Schema
334 opaxxml.xsd. The schema had the correct spelling of this member always.
335 The ASN.1 was mis-spelled and still is (API change) - we are
336 not changing this. However, the OPAC to XML conversion had yet
339 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
342 New function, z_ext_record_oid_nmem, which is similar to
343 z_ext_record_oid but takes NMEM rather than ODR
345 --- 4.2.49 2013/01/18
347 ICU: New conversion element 'join' which joins tokens into one
348 with a custom character given by rule attribute.
350 --- 4.2.48 2013/01/10
352 New GFS search member: present_number. This is a hint to the
353 search handler how many records are going to be fetched immediately
354 following search. There's no guarantee that it's going to be the case,
355 since it depends on hit count (for Z39.50 piggyback) and whether errors
358 Make a few functions static (private). The functions getbyte_stream,
359 ungetbyte_stream and yaz_gets are now private. They were never declared
362 yaz-marcdump: exit(5) for serious decoding errors
364 ISO2709 decoding: be more picky WRT header
366 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
367 was only used as to indicate that next-result-set-position should be
369 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
370 Based on patch from Ashley Sanders.
372 Make some functions static/private in PQF parsing. Those functions were
373 never declared in a public header and so should not be in use by
374 applications based on YAZ.
376 --- 4.2.47 2012/11/23
378 ZOOM: special options to control APDU logging.
379 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
380 logging of APDUs until "saveAPDU" option is set again. If logging is
381 already enabled the effect is that current APDU buffer is cleared.
382 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
383 logging (default behavior on new connection).
384 The APDUs sent/received can be obtained by using
385 Using ZOOM_connection_option_get(c, "APDU") or
386 ZOOM_connection_option_getl(c, "APDU", &l).
388 GFS: relay implementation_version from backend
389 From 3.0.40 and later, implementation_version from backend was
390 not used in init response at all.
392 --- 4.2.46 2012/11/15
394 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
395 mode at all. Probably never did.
397 Make a new version of ztest.pem that, at least, is not expired.
399 --- 4.2.45 2012/11/13
401 Fix description of CCL directive 'case'.
403 More tight checking of form arguments (yaz_uri_to_array). Makes
404 YAZ better at rejecting big and/or bad POSTs.
406 SRU decoding does not report more than up to 10 invalid arguments.
408 rpn2cql: less quotes in generated terms. Semantics unchanged, but
409 it's prettier this way.
411 --- 4.2.44 2012/10/25
413 New utility yaz_decode_init_diag. Defined in proto.h.
415 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
416 given for unix local socket.
417 The COMSTACK string for doing so is:
420 unix:/myfile:tcp:localhost:9999/mybase
421 unix:/myfile:localhost:9999/mybase
422 unix:/myfile:http://fakehost/mybase
424 debian: Use dpkg-buildflags in build process.
426 --- 4.2.43 2012/10/19
428 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
429 global's SRU service uses a recordPosition scheme starting from zero.
430 First record's position should be one
431 according to the standard.
433 --- 4.2.42 2012/10/18
435 Allow more namespaces for SRU. This is to allow, for example, an
436 incorrect namespace returned from server
437 http://services.igi-global.com/sru .
439 Minor fixes for compilation on Windows.
441 --- 4.2.41 2012/10/11
443 daemon: log total number of bad signals from child on stop so that it
444 is more easy to spot problems with child worker processes.
446 retrieval: empty backend name attribute omits element set
447 from being used in retrieval.
449 --- 4.2.40 2012/10/04
451 Implement Solr sort strategy "solr", similar to sru11 sorting.
452 This will implement the correct parameters on Solr requst to do
455 --- 4.2.39 2012/09/28
457 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
460 MARC: Extra/missing indicator handled for MARCXML.
461 The indicator length is given in header and is the same for the
462 whole record. If attributes ind1, ind2 are missing, then content
463 character defaults to blank. Extra indicator attributes (beyond)
464 indicator length are treated as an error.
466 Reformat: delete trailing whitespace
468 --- 4.2.38 2012/09/17
470 MARC: fix non-ASCII characters for leader. This is to ensure we can
471 generate XML in UTF-8.
473 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
474 in one node with structure word.
476 --- 4.2.37 2012/09/04
478 yaz-json-parse: JSON output may be pretty printed by using option
481 Increase default value of max message for Z39.50 Init for GFS, ZOOM
482 and yaz-client. Old value was 1 MB. New value is 64 MB.
484 --- 4.2.36 2012/08/22
486 yaz-client: don't display bogus records from SRU servers. Some SRU servers
487 return more records than given by *maximumRecords*. Skipping those in
490 record_render: simplify buffer return handling and fix at least one bad
491 memory reference, that broke the test_embed_record sometimes.
493 Allow http://user:pass@host notation for yaz_url_exec.
495 zoomsh: allow shell command to be executed. Via the system(3) call.
497 yaz_poll: Allow num_fds == 0
499 yaz-client: fix bad encoding of "itemorder item". The itemorder
500 item <no> - command forgot to use length of encoded Item Request
501 package. Error present since YAZ 3.
503 yaz-ztest: fix bad usage of session handle. Bug was introduced when
504 result sets were saved (271a9c83).
506 SRU recordPacking: guess record packing in response rather than looking
507 at the recordPacking element which, OF COURSE, changed semantics in SRU
510 Decode SRU 2.0 responses. The official namespace for responses, according
511 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
512 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
513 nature.com's server, however, usee namespace
514 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
515 we are now using a glob-expr to match up the namespace. ZOOM C and
516 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
517 I can not find a single real example showing the "real" namespace in
518 the documentation from OASIS. The namespace for requests is different
519 from responses, but this is not added to YAZ yet, when we don't encode
522 --- 4.2.35 2012/06/26
524 zoom/record_render: add support for Base64 decoding fo MARC records
525 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
526 which will decode base64 + ISO2709 marc-8 encoded material from text node
529 --- 4.2.34 2012/06/07
531 Add missing definitions ZOOM_resultset_get_facet_field_by_index
532 and ZOOM_resultset_facets_names.
534 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
537 Change APDU dump printing to avoid long leading blanks. For levels 16
538 or larger the level is shown and the indentation is truncated but
539 recursed with modula 8. This makes it still reasonable easy to read
540 - even for nested BER dumps.
542 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
543 return 0 (incomplete package) in case where the BER package was
544 considered too nested (return value of -2).
546 dumpber: lines of level 15 are not indented further. Two spaces per
547 indentation; indentation 15 or more is indented to a fixed indentation
548 and augmented with a level=<no> indication.
550 zoomsh: increase max size of command+args
552 GFS: No limit in RPN buf size in CQL to RPN conversion.
554 --- 4.2.33 2012/05/09
556 New function for daemon utility, yaz_daemon_stop .
558 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
560 --- 4.2.32 2012/04/25
562 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
563 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
565 --- 4.2.31 2012/04/23
567 YAZ daemon utility relays SIGUSR1 to child process.
569 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
570 would result in en empty database list - which in turn would result in
571 encoding failure for search.
573 Fix reading beyond string in yaz_sort_spec.
575 --- 4.2.30 2012/04/11
577 Add two new SRU diagnostics:
578 236: Access to specified database denied
579 1015: Init/AC: Maximum number of simultaneous sessions for Userid
581 Document the very useful ZOOM-C option "apdulog".
583 CQL to RPN: term may be passed through verbatim. This is enabled with
584 truncation.cql . The assumption being that the term is already CQL.
586 --- 4.2.29 2012/03/20
588 record_conv: leader spec may be given for marc element.
589 The leader spec is given as attribute leaderspec for element marc.
590 For example to convert a MARC21 record from MARC-8 to UTF-8:
591 <marc inputformat="marc" outputformat="marc"
592 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
594 record_conv: allow user-XSLT params. For example:
595 <xslt stylesheet="MARC21slim2DC.xsl">
596 <param name="myparameter" value="myvalue"/>
597 <param name="otherparameter" value="othervalue"/>
600 record_conv: fix error handling for missing marc charsets.
602 CQL: fix extra terms in wrong order.
604 --- 4.2.28 2012/03/06
606 record_conv: modify new API for conversion types. The conversion types
607 may be passed in new functions yaz_record_conv_configure_t and
608 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
610 Avoid mixed statement/variable declare; fixes compilation with Visual
613 --- 4.2.27 2012/02/28
615 Add non-standard SRU diagnostic: 235: "Database does not exist".
616 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
617 Update SRU to Bib-1 diagnostic maps accordingly.
619 CCL: add two new diagnostics for unsupported masking. The new
620 diagnostics are: "Embedded truncation not supported" and
621 "Single charcacter mask not supported".
623 --- 4.2.26 2012/02/23
625 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
627 --- 4.2.25 2012/01/11
629 Build YAZ for Ubuntu Oneiric.
631 CCL: allow parantheses for proximity operands. For example CCL query
632 (a) % (b) is now allowed.
634 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
635 marked dead, rather then being destroyed. If not, the session memory is
636 being free'd before the search/scan handler is finished. Also destroy
637 'request' memory in request_release rather than in various places,
638 which resulted in leaks from time to time.
640 --- 4.2.24 2011/12/21
642 cql_sortby_to_sortkeys: honor sort prefix.
644 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
645 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
646 The rpn2cql family of functions now always returns quoted CQL terms.
648 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
650 --- 4.2.23 2011/12/15
652 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
653 sequence is treated as one. For example, &&a=b&&&c& is identical to
656 --- 4.2.22 2011/12/05
658 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
659 APDUs for a connection to a WRBUF.
661 --- 4.2.21 2011/11/23
663 Fix cql_sortby_to_sortkeys. Completely broken before.
665 Make CCL's @truncation work again.
667 --- 4.2.20 2011/11/09
669 New ZOOM connection setting: tproxy. It's like proxy, but does not
670 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
671 to set resolved address + port for a connection outside ZOOM itself.
673 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
675 --- 4.2.19 2011/11/07
677 Fix uninitialized variable in Solr spell support (could cause SEGV
678 for SRU response decoding).
680 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
681 back-end's addinfo through into the ZOOM response addinfo.
683 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
684 they are separated by a colon and a space rather than simply
687 --- 4.2.18 2011/10/28
689 Add support for Solr spell-checking/suggestions through ZOOM.
690 If a Solr target has been configured correctly for spelling-checking
691 and suggestions, these will now be returned on the ResultSet option
692 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
694 --- 4.2.17 2011/09/28
696 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
697 with a flag whether to substitute escape sequences or not.
699 --- 4.2.16 2011/09/22
701 Fix nmem_strsplit_escape to substitute escape char properly.
703 New option for zoomsh -e , which makes it abort on first error and
704 return process exit code to indicate success/failure.
706 YAZ options utility supports special option -- which makes all it treat
707 all following arguments as non-options.
709 --- 4.2.15 2011/09/16
711 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
712 searched if absolute filename is given.
714 Fix conv_xslt() error-reporting when stylesheet is not found.
715 (The value of fullpath is meaningless in this situation.)
717 --- 4.2.14 2011/09/07
719 Fix problem in CQL sort node creation: un-initialized memory.
721 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
722 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
723 CQL sortby depending on whether Type-1 or CQL is actually sent to the
726 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
727 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
729 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
730 will make it possible to use both single-character mask (#) and wildcard (?)
731 in CCL . Throw diagnostic for left truncation because that is not supported
734 --- 4.2.13 2011/09/01
736 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
737 cases using escapes (\-sequences) and masking.
739 PQF parse fix: A trailing backslash followed by end-of-string (\0)
740 would result in a read one byte beyond string.
742 rpn2ccl may use Z39.50 masking for terms (t=z).
744 ICU check fix. Don't include library -lCrun on Solaris, unless present.
746 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
747 not --cppflags (which seeems like an error in icu-config).
749 --- 4.2.12 2011/08/27 RPM package only
751 cql2ccl: fix conversion of terms: operator characters were not
754 --- 4.2.11 2011/08/25 RPM package only
756 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
757 CCL parser will map both # and ? to their regular expression
758 quivalents (. and .*).
760 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
761 of reserved CQL characters.
763 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
764 is, so that they are passed through.
766 --- 4.2.10 2011/08/24
768 ZOOM SRU mode: more aggressive re-connect.
770 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
771 made available as a utility function, declared in <yaz/logrpn.h>
773 rpn2cql_structure() supports proximity nodes (except that the Type-1
774 proximity node's "exclusion" binary is ignored, as there is no way to
775 express that in CQL). Fixes bug #4564.
779 Fix SEGV that could occur if set command of zoomsh was given without
780 value (2nd argument).
782 Fix SEGV that could occur if unsupported transport was given for
783 COMSTACK - say https (when SSL was unavailable).
785 Build yaz-url on Windows too.
789 New utility to get web content. Header is url.h. A command line tool
790 yaz-url is part of the distribution and packages.
792 Fixes for SSL COMSTACK (when gnutls is in use).
794 New functions yaz_base64{encode,decode}. Header is base64.h.
798 ZOOM C includes HTTP response buffer as additional info if it fails
799 to decode the SRU response.
801 Make wrbuf_json_puts available.
805 zoom: throw diagnostic for invalid value for option "sru". Before a
806 bad SRU request was sent.
808 Adding new utility wrbuf_vp_puts.
810 Add cclxmlconfig.obj to win/makefile. It was missing completely.
814 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
815 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
816 redirect was used at the same time.
818 MARC line mode decoding: be less picky about length given - first
819 5 digits of header that is.
821 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
823 Changes to decoding of SRU records: a record with recordPacking=xml is
824 modified with a new root element <yaz_record> if the recordData contains
825 multiple children elements. This is to make the record XML parseable
828 RPN to Solr conversion: encode special characters.
830 Generic Frontend Server: fix uinitialized member, stepSize.
834 Fix a bug in SRU decoding of records.. The database records stored
835 had un-initialized memory, but it would only be seen with yaz_record_render
836 and type_spec="ext" .
838 Fix a bug in ccl_qual_dup introduced in 4.2.3.
842 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
846 Add new utilities to convert from CQL to CCL . These utilities have
847 prefix cql_to_ccl defined in cql.h.
849 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
850 lead to memory heap corruptions when ICU utilities were in use.
854 Make compilation work without Libxml2.
856 yaz-client: remove redundant blanks in display of searchResult-1 term
861 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
862 resulting CQL node (tree) in a new node CQL_NODE_SORT.
864 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
865 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
866 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
867 Note that the CQL sortby spec is only converted when the GFS is already
868 converting from CQL to RPN (cql2rpn element).
870 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
871 specify whether to collapse delimitors or not. The existing nmem_strsplit
872 do collapse (collapse parameter = 1).
874 Windows installer: For NSIS, set InstallDir depending on x86/x64.
876 Rename internal func yaz_use_attribute_create. While non-static, this
877 function is not declared in a public header.
881 Add -lCrun when linking with ICU on Solaris.
883 More quicks character set conversions for OPAC records.
887 fix problem with record_render: records were converted (character set
888 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
892 SRU: add methods for handling DADS SRU-proxy facets.
894 Separate OPAC record character set for ZOOM_record. yaz_record_render
895 allows a character set given as charset=from/opacfrom,to where 'from' is
896 the character set of a bibliographic record, 'opacfrom' is character set
897 of OPAC record and 'to' is the target character set.
901 yaz-client: show may XML format records. Command show followed by 'format'
902 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
905 src/stemmer.c: Avoid using unnamed union. It is not supported by some
908 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
911 Update yaz.spec to operate on both SLES11 / Centos 5.5.
913 RPM: Release includes 'indexdata' name. Use indexdata in release name so
914 this package can be distinguished from other vendors.
916 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
917 as determined by configure
919 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
921 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
922 returns no error and no record, the present request is considered
923 partial (only a subset of the records could be returned by backend), and
924 so it is appropriate to set Present Status to partial-4.
928 Move yaz-config man pages to section 1.
930 More documentation about Solr.
932 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
933 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
934 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
935 peers on some Linux systems. However, in general that does not work
936 so YAZ can not rely on that to work. Debian changed behavior in this
937 respect from Debian lenny to Debian squeeze (still testing as of Oct
939 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
941 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
945 Fix yaz-config output: echo_source not set correctly by configure.
949 Solr Web Service support for yaz-client and ZOOM.
951 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
953 --- 4.0.12 2010/08/17
955 Z39.50 facet support. Facet specifications are passed for search in
956 other-information with ASN.1 as defined in facet.asn and OID
957 .10.1000.81.5 . Facets are expressed as an Attribute list as known
958 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
959 3 is limit (number of entries to get in response). yaz-ztest returns
960 dummy facets if a client asks for them.
962 --- 4.0.11 2010/07/09
964 CCL fixes: bug 2895 and bug 3539.
966 GR1-display: add comma in display - was removed by mistake in
969 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
971 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
973 --- 4.0.10 2010/06/18
975 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
976 result set from a connection. The result set will be on its own
977 thereafter; no operations on it will perform retrievals from a target.
978 Only cached copies are returned.
980 ZOOM C:fix case for HTTP servers responding with Connection:close.
981 Ensure that if there is a current task it is resumed (like fetching
982 more records in a result set) . Bug #3484.
984 PQF parser: use odr_atoi for Odr_int (not atoi)
986 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
987 values that contain any non-digits are treated as string attributes
988 (previously decoding only checked for leading character ([0-9]). PQF
989 encoding: attribute string values are not surrounded by double-quotes.
993 New utility for managing threads - thread_create.h.
995 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
996 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
997 but YAZ' implementation do.
999 Fixes for yaz_cond-functions on Windows 7.
1001 DLL export more symbols.
1003 zoomsh: show record do NOT render opac.
1005 Remove *.la files from Debian and RPM packages.
1007 --- 4.0.8 2010/05/11
1009 Debian package libyaz-dev depends on libgnutls-dev again (was
1010 removed in YAZ 4.0.6, but due to Libtool it is still needed
1011 even though yaz-config do not list libgnutls libs).
1013 ZOOM: Use only one WRBUF for returning string results for
1014 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1016 ZOOM: ZOOM_connection do not use a shared pointer to
1017 ZOOM_resultset after ZOOM_resultset is destructed by
1018 user. Reverts to YAZ 4.0.4 behavior.
1020 --- 4.0.7 2010/05/04
1022 record-conv: fix problem with at least one XSL conversion -
1023 due to probably incorrect usage of XML XSL documents.
1025 --- 4.0.6 2010/04/29
1027 Fix yaz-config for static mode and the use of SSL (gnutls).
1029 --- 4.0.5 2010/04/29
1031 Forward decl timeval struct in mutex.h and gettimeofday.h.
1033 yaz-config: fix 'static' mode linking.
1035 --- 4.0.4 2010/04/28
1037 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1038 are wrappers for pthreads or Windows. For Windows these are put in
1039 a separate DLL: yaz_cond4.
1041 libyaz.la (whole source) is compiled with thread. If thread support
1042 is enabled enabled, all source of YAZ is compiled with treading support.
1043 This allows core utilities such as yaz_log to use thread facilities.
1044 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1045 thread utilities. This commit moves mutex utilities (mutex.c) from
1046 libyaz_server.la to libyaz.la.
1048 yaz-json-parse displays leading text until error.
1050 --- 4.0.3 2010/04/09
1052 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1053 patch from Giannis Kosmas.
1055 SRU: no longer URL encode SRU database. The URL for an SRU server is
1056 a URL and such is alreeady encoded - at least when given with leading
1057 http:// or https://. This reverts behavior to YAZ 3.0.50.
1059 Support for new MARC XML notation TurboMARC which like MARCXML is a
1060 complete representation of MARC/ISO2709.. This one, however, is more
1061 compact and allows for faster processing with XSLT. TurboMARC can be
1062 used in the marcdisp.h API, from the yaz-marcdump utility and from
1065 yaz-ztest can be configured - via the database - to perform certain
1066 delays when it performs operations search, present and single record
1067 fetch. This allows testers to make yaz-ztest act as a real or even slow
1068 Z39.50 server. Refer to the yaz-ztest man pages for details.
1070 --- 4.0.2 2010/03/09
1072 wrbuf_destroy allows NULL WRBUF passed to it.
1074 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1076 Add ZOOM_connection_close.
1078 No fixed size buffers for ZOOM shell - bug #3257.
1080 tstodr: make it work on s390 platform.
1082 New icu iterator-functions. The new icu_iter-functions makes it possible
1083 to use ICU chains from many threads.
1085 yaz-client: better syntax check for show command.
1087 --- 4.0.1 2010/01/26
1089 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1092 New simple local-file XML include facility which allows file glob-patterns.
1093 Refer to yaz/xml_include.h.
1095 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1098 ZOOM_record_get supports new parameter "format" which makes it format XML
1101 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1102 JSONText in ECMA-262) is JSONValue, not JSONObject.
1104 --- 4.0.0 2010/01/20
1106 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1107 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1109 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1110 POSIX/Unix builds .so with major version 4.
1112 Remove old LOG_-defines from log.h. They have been obsolete and
1113 undefined by default for the last 5 years.
1115 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1117 GFS: Remove socket (int *fd) from search_rr handler. The socket
1118 descriptor ptr is a facility that allowed a search handler to supply
1119 a socket which would serve as a callback - when search was complete.
1120 This facility has now been in use for years.
1122 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1123 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1124 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1125 returns 'const char *' rather than 'char *. The returned string is
1126 read-only and should not be modified by applications. COMSTACK cs_close is
1127 now a void function - it no longer returns int. No applications check for
1128 the value and the implementations has always returned 0.
1130 ZOOM: use size_t for scan hit counts and str size. Functions
1131 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1132 occ (hit count) and len (string length) are now of type size_t pointer
1133 rather than int pointer. This is to be able to represent large hit counts
1134 and to also just to use the proper type for string length (strlen result).
1136 New JSON parser. Refer to include/yaz/json.h .
1138 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1139 Used to be int in some cases. Many wrbuf_-functions used to return an int
1140 indicating some length.. These return values were never used. And so they
1143 ODR: odr_malloc, odr_total now takes size_t for size.
1145 clone_z_type: fix leak; occurred for encoding failures.
1147 --- 3.0.52 2009/12/03
1149 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1150 bug was introduced in 3.0.51.
1152 --- 3.0.51 2009/12/02
1154 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1156 tcpip comstack: fix leak for getaddrinfo.
1158 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1159 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1160 Decoding of SRU "path" database is performed by private function
1161 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1162 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1164 yaz-client: honor base command for SRU. Change when database setting
1165 is applied for SRU and ensure it is kept when a connection is reset.
1166 Change also the way errors are displayed or SRU (decoding of packages).
1168 --- 3.0.50 2009/11/02
1170 Add support for extra request / response data for SRU codecs and GFS.
1171 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1172 for extra data response buffer and length. For the GFS, both request
1173 and response data (XML) is carried in extra_args and extra_response_data
1174 for the search handler. Patch by Ko van der Sloot.
1176 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1177 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1178 10010). This fixes bug #2113.
1180 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1181 cmdfile included a 'quit' command that would result in a memory violation.
1183 --- 3.0.49 2009/10/01
1185 Make a number of functions defined in xmlquery.c static. These have
1186 never been declared in a public header file (yaz/xmlquery.h) and was
1187 made public by mistake.
1189 Improve speed of character conversions (iconv utilities). This makes
1190 conversions from MARC-8 faster.
1192 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1193 unless type desired is "raw". This will prevent type "xml" from
1194 returning ISO2709 .. Which obviously can not be XML parsed.
1196 Fix memory leak in ZOOM that would occur if option apdulog was used
1197 on a re-used connection.
1199 Frontend server logs HTTP requests.
1201 Frontend server now sends Z39.50 close when it times out (sesssion has
1202 been idle for too long). Versions 2.0.30 and earlier also sent close.
1203 But due to a mistake this was disabled in all versions after that, i.e.
1204 the server would just close the socket immediately.
1206 yaz-client emits a better message when receiving an unrecognised
1207 userInformationField.
1209 Skip zero-length subfields when decoding ISO2709. This rare case happens
1210 if a record has two FS characters in a sequence. Without this patch
1211 there would be a reference beyond char array in using_code_len fragments
1214 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1216 --- 3.0.48 2009/08/28
1218 The show command offered by the zoomsh command now takes a 3d optional
1219 parameter type which is what is passed to ZOOM_record. If the type
1220 argument is omitted, "render" is used.
1222 RPN to CQL conv may use USE string attributes (bug #2978).
1224 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1226 --- 3.0.47 2009/07/08
1228 Function yaz_xml2query allows a diagnostic element in the PQF XML
1229 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1230 code and additional info respectively.
1232 The BER BOOLEAN is now the integral type Odr_bool which still happens
1233 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1234 typedef'd to Odr_int. This is still an integral 'int', but it may be
1235 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1236 ASN-1 compiler as well as programs has been updated to use the new types.
1238 --- 3.0.46 2009/06/08
1240 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1241 only the bibliographic record was rendered. For type=opac, an OPAC
1242 record is only returned if it is present.
1244 iconv: small fix for encoding of advancegreek.
1246 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1248 yaz-client: option auto_reconnect=on really reconnects.
1250 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1252 server: avoid null ptr ref for for yaz_poll errors.
1254 build: fix RPM build for RHEL 5.3.
1256 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1258 --- 3.0.45 2009/03/31
1260 Fixed bug #2709: TCP connect returns Invalid argument.
1262 Fixed compilation for mingw.
1264 Honor charset for raw records (ZOOM_record_get).
1266 Fixed use of errno for threaded mode that was seen on Solaris 10.
1268 Fixed argument passing with blanks in value for Windows Service.
1270 Disable YAZ' own log rotate by default (no 1 GB limit).
1271 The variable l_max_size which specifies the log file limit is set to 0
1272 (DISABLED): This is due to the fact that YAZ is most often deployed using
1273 logrotate. Also YAZ can not perform log rotate because of unsufficient
1274 permissions (setuid).
1276 --- 3.0.44 2009/02/17
1278 List supported encodings in man page for yaz-iconv.
1280 Fixed missing SSL libs for --libs output
1282 Re-established OID record syntax application-xml. Nobody should use it
1283 but we don't want to change soname because of this symbol being absent.
1285 --- 3.0.42 2009/02/02
1287 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1289 Added member named_result_sets for init handler struct for the GFS. This
1290 allows a server to disable named result sets.
1292 Removed OID record syntax application-xml.
1294 Added support for rule-based transliterator for ICU wrapper of YAZ.
1296 Fixed bug #1902: yaz-icu XML output.
1298 Make YAZ checks Emacs friendly.
1300 BITSTRING value shows value. Bug #2346.
1302 ISO2709 decoding: skip control characters from indicator data.
1304 Omit sort key by default in yaz-icu's output.
1306 Allow combined single char options (again) for YAZ' options function.
1308 Utility yaz-marcdump got option to display YAZ version (-V).
1310 Allow YAZ to use ICU 3.4.
1312 Added new ICU test case which illustrates removal of diacritics.
1314 --- 3.0.41 2008/12/29
1316 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1318 --- 3.0.40 2008/12/29
1320 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1323 Fixed bug #2352: yaz-marcdump crashes for certain record.
1325 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1327 Added support for Danmarc2 to UTF-8 conversion.
1329 Added support for ISO5426 to UTF-8 conversion.
1331 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1332 implementation version.
1334 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1336 --- 3.0.38 2008/11/10
1338 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1339 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1341 ZOOM C now interprets databaseName option for ZOOM connection as path
1344 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1346 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1348 Dummy Libxml2 types no longer defined in headers of YAZ'.
1350 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1353 --- 3.0.36 2008/09/26
1355 Various ODR chapter fixes.
1357 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1359 Added missing source for Windows compilation, mutex.c.
1361 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1363 For SRU connections in ZOOM all records up to "count" are now fetched.
1365 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1366 in Windows due to bad error handling for Libxml2.
1368 Added facility for sending arbitrary records (ASN.1 any) using
1369 ZOOM C's Extended service update. Patch by Sam Reynolds.
1371 New options for ZOOM C's connection, logapdu which makes ZOOM log
1374 --- 3.0.34 2008/06/18
1376 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1378 --- 3.0.32 2008/06/12
1380 Fixed memory violation that could occur when decoding UTF-8. This bug
1381 was only present in 3.0.30 of YAZ.
1383 --- 3.0.30 2008/06/06
1385 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1386 GNU TLS is used by default (if found).
1388 yaz-ztest returns OPAC records if a client asks for OPAC.
1390 Improved speed of MARC-8 encoding.
1392 Added support for lossy and loss-less MARC-8 encoding.
1394 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1396 Added new Windows Service wrapper (sc).
1398 yaz-client's itemorder command may now send a file.
1400 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1402 Added new function yaz_log_xml_errors.
1404 Allow (but warn) unknown XML attributes in MARCXML parsing.
1406 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1408 The UTF-8 to MARC-8 conversion now uses a different set of characters
1409 for Greek symbols. Bug #2120.
1411 --- 3.0.26 2008/02/21
1413 Added yaz_daemon (daemon.h).
1415 Fixed bug #2068: pkg-config trouble
1417 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1419 --- 3.0.24 2008/01/28
1421 Document --with-xml2 option.
1423 Added OPAC XML XSD (etc/opacxml.xsd).
1425 Allow glob mask for name attribute in retrieval element for the
1426 generic frontend server's retrieval facility.
1428 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1429 except POLLIN/POLLOUT.
1431 Fixed error handling in cs_listen. Bug #2037.
1433 --- 3.0.22 2008/01/20
1435 Fixed version in yaz/yaz-version.h.
1437 Fixed bug #2027: Crash when closing connection.
1439 Changed configure so that ICU support is only enabled if only ICU
1440 and Libxml2 is available (because the ICU chain is XML based).
1442 --- 3.0.20 2008/01/15
1444 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1445 is built. Only this DLL depends on the ICU runtime.
1447 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1448 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1450 Changed license of CCL module to 'Revised BSD'. After consultation with
1451 remaining members of the original EUROPAGATE consortium, we are re-issuing
1452 the CCL module without a separate license. The software was developed by
1453 Index Data as part of a research project. The special license was included
1454 to help feed usage information back to the project consortium to support
1455 project evaluation. At this time, the project consortium has long-since
1456 disbanded, and the majority of the original principals have retired. At the
1457 same time, we have significantly modified the software during the following
1458 years, to the point where very practically no original code remains. To
1459 simplify re-use of the software, we have contacted those members of the
1460 consortium who could be reached, and agreed to re-issue the module as a
1461 proper part of the YAZ package.
1463 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1465 CQL closer to being version 1.2 compliant. CQL also allows free-form
1466 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1469 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1470 bug could make Extended services handling crash in the ZOOM layer. This
1471 bug was only present in YAZ 3.0.18.
1473 --- 3.0.18 2007/12/19
1475 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1478 yaz-marcdump reads and writes collection wrapped records.
1480 Handle OPAC for record conversion module.
1482 Fixes for ICU wrapper.
1484 Allow ICU libs to be controlled with --with-icu .
1486 --- 3.0.16 2007/11/12
1488 Added yaz_poll which is a wrapper for select/poll. When poll is available
1489 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1490 sockets to be in use.
1492 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1493 functionality through an XML based configuration (ICU chain). This system
1494 is useful for search facilities such as Pazpar2 and Zebra that needs to
1495 perform tokenization of indexed material. The ICU code in a separate
1496 library libyaz3_icu.a.
1498 Added HTTP tunnel facility for COMSTACK, bug #1752.
1499 This is a facility that allows a Web proxy, such as squid, to tunnel
1500 Z39.50 traffic. This facility is "transparent" to must applications
1501 using YAZ. It's enabled by using pseudo transport connect: followed by
1502 the proxy address, followed by command, then follwed by he regular
1503 "virtual" addresss. For example,
1504 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1506 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1508 --- 3.0.14 2007/09/21
1510 Fixed bad memory reference in ZOOM_record - cuased by member not being
1511 initialized. This was a problem only in YAZ 3.0.12.
1513 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1514 fields were not removed.
1516 Changed the way C code is generated from codetables.xml. Made a MARC-8
1517 conversion trie for each characterSet section rather than codeTable.
1518 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1519 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1521 --- 3.0.12 2007/09/12
1523 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1524 from ZOOM_record_error).
1526 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1528 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1530 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1532 Better SRW-to-Bib-1 diagnostic mapping.
1534 ZOOM C and yaz-client announces SRU version 1.2 by default.
1536 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1539 Fixed in yaz_sru_decode to allow other version than 1.1.
1541 --- 3.0.10 2007/08/22
1543 Added support for SRU scan for ZOOM.
1545 Added support for the use of the older versions or Extended Service
1546 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1547 set to the version , 1=first, 2=second, 3=third. The third version is
1548 what ZOOM C has used so far. And that, obviously, is the default.
1550 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1551 therefore in Zebra and in SimpleServer-based applications). The new
1552 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1553 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1554 which is passed into the back-end search callback function.
1556 Added support for HTTP Basic authentication in clients: the SRU/W
1557 codec encodes the username/password elements of the PDU structure
1558 appropriately, and these may be set using the "user" and "password"
1559 options in ZOOM-C applications (the same options that are used for
1560 Z39.50 authentication).
1562 --- 3.0.8 2007/06/25
1564 Fixed bug #1208: SSL appears to be broken in ZOOM.
1566 Fixed bug #1206: Libxml2 include path weirdness.
1568 Added oid_name_to_dotstring.
1570 Allow elementSetName to be specified for ZOOM C record update.
1572 Allow waitAction to be specified for ZOOM C based for Extended Services.
1574 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1575 syntax OID. Bug introduced in YAZ 3 series.
1577 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1579 --- 3.0.6 2007/06/06
1581 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1582 directory. yaz-client now reads commands from file given by option -f
1583 if specified; then tries to read .yazclientrc in current directory.
1584 Failing that, it reads .yazclientrc from user's home directory.
1586 Added support for correlationInfo Note and ID for Record Update via
1589 Added yaz-client command querycharset which specifies character set for
1590 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1591 (termListAndStartPoint).
1593 Charset ISO5428:1984 is an alias for ISO5428-1984.
1595 Implemented a way to perform scan in a result set using Z39.50. This
1596 is achieved by attaching the result set name in the characterInfo
1597 (type InternationalString) of OtherInformation in the Scan Request PDU.
1598 The result set is identified in the otherinformation by the new OID:
1599 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1600 This allows for scan in result set and faceted search . Zebra did some
1601 of this in the APT term using attribute type 8 and value being result
1602 set. Using the OtherInformation approach for this is cleaner and easier
1603 to work with in proxies and the like. This facility can be used in
1604 yaz-client using new command setscan which takes a result set as first
1605 argument, start position (APT) as second.
1607 Changed decoding of SRU XML packed records to deal with servers that
1608 have recordData with XML data with multiple root nodes. Also make
1609 comparison for recordPacking case insensitive. Again, one server
1610 returns "XML" where others return "xml".
1612 For SRU responses allow Content-Type application/xml as well as text/xml.
1614 --- 3.0.4 2007/05/21
1616 Fixed bug in character set conversion of BER strings. Bug introduced
1619 --- 3.0.2 2007/05/08
1621 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1623 For OID class, use oid_class consistently.
1625 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1628 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1629 character set for bibliographic information interchange". By Giannis Kosmas.
1631 Added documentation on new OID API.
1633 --- 3.0.0 2007/05/02
1635 Changes to generic frontend server interface: added new member
1636 'query_charset' for bend_initrequest structure. A backend init handler
1637 should set this member to its native character set for query terms.
1638 When defined, the frontend server logic will announce this character set
1639 to a client if the negotiationModel bit is set by the client. All server
1640 implementors are encouraged to specify this. If a backend server does not
1641 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1643 Added CCL utility to remove terms (stop words) from resulting RPN
1644 tree. This is handled by functions with prefix ccl_stop_words_ .
1646 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1647 terms in RPN queries.
1649 Clean-up the CCL API. Moved some internal structures from ccl.h to
1650 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1651 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1652 This is replaced by ccl_parser_find_str which takes a string instead.
1654 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1655 libyaz.la is the core of YAZ except the generic frontend server and
1656 does not depend on POSIX threads anymore. libyaz_server.la is the
1657 generic frontend server facilities and uses POSIX thread functionality
1658 if available. The libyaz.la no longer depends on POSIX threads because
1659 the number of global structures is limited. NMEM no longer re-uses blocks
1660 between threads ; it simply free's memory immediately but allocates in
1661 "large" chunks as usual. We don't expect any performance penalties
1662 because of this. The yaz_log system is still using a global log_level so
1663 caution must be taken when modifying it with yaz_log_init_.. +
1664 yaz_log_mask_str. This, however, should not cause any trouble because
1665 these functions are called during initialization of application code
1666 anyway. `yaz-config --libs server` returns libs for server applications;
1667 `yaz-config --libs` returns libs for non-server applications.
1669 New OID database - with public definitions in oid_db.h. Removed old OID
1670 database including the head oid.h and definitions such as enum oid_value
1671 and struct oident. The new OID database uses the same string names as
1672 before but the 'protocol' is gone. There are now only two representations
1673 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1674 converts from string to OID; functions with prefix yaz_oid_to_string
1675 converts the other way.
1677 Change to emit_term() in CQL-to-PQF query translation: when a term has
1678 the /regexp relation modifier, do not process it for leading and
1679 trailing "^" and "*", which have quite different meanings in regular
1682 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1683 write handlers no longer carries a 'last' parameter. This will make
1684 yaz_iconv flush "less" characters. A flush is performed by call to
1685 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1687 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1688 removed, because function yaz_query_to_wrbuf does the same.
1690 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1691 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1693 Deprecated MARC utility functions removed.
1695 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1698 Branch split: YAZ_2_1_55_branch
1700 --- 2.1.54 2007/03/16
1702 Fix to ZOOM-C so that transparent reconnection is properly handled on
1703 connections that are in asynchronous mode.
1705 Fixed compilation on OpenBSD 4.0.
1707 Large strings in GRS-1 records are now properly displayed in yaz-client.
1709 Added character conversion support for "advancegreek"; based on patch from
1712 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1713 sequence is met. Before the error was not set so it would be unknown.
1715 Adjust yaz-marcdump MARC reader so that it skips until record separator
1718 --- 2.1.52 2007/03/07
1720 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1721 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1722 fd_set structure used as a bitmask for the FDs to be selected on.
1724 Using ACX_PTHREAD macro to check for POSIX threads.
1726 Fixed have-vsnprintf check.
1728 --- 2.1.50 2007/02/23
1730 Fixes for configure on BSD. Bug #900.
1732 Added snprintf/vsnprintf wrappers for systems that don't have
1733 limits (heavens forbid).
1735 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1736 created before all previous tasks were completed and removed from the
1737 task queue, the new task could be removed by a mistake.
1739 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1741 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1743 Fixed bug #832: Problem with MARC/charset in yaz-client.
1745 Fixed bug #668: save command line history for yaz-client.
1747 Fixed bug #830: pkg-config support.
1749 --- 2.1.48 2007/01/23
1751 Extended ZOOM result set options with two options that may be read by
1752 a client: resultSetStatus and presentStatus with values as specified for
1754 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1756 Fixed bug #827: Using SSL fails on Debian etch.
1758 Fixed bug #826: Weird looking chars for set of MARC records.
1760 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1761 that is treated as an ItemOrder with itemRequest being an XML document
1762 external. The value of "doc" is the content.
1764 Extended the GFS search facility. New member of bend_search_rr
1765 'estimated_hit_count' signals that hits is known to be an estmate
1766 (higher or lower than real hit count). New member 'partial_resultset'
1767 signals that the search was partial (hit count is lower or equal than
1768 real hit count). For Z39.50, the information is stored in resultSetStatus
1769 member of SearchResponse APDU. For SRU, the information is signalled
1770 via SRU diagnostic 59: "Result set created with valid partial results
1773 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1775 --- 2.1.46 2007/01/13
1777 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1779 Added ZOOM_connection_peek_event.
1781 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1782 the following new functions:
1783 ZOOM_event_nonblock, ZOOM_connection_process,
1784 ZOOM_connection_get_{socket,mask,timeout},
1785 ZOOM_connection_fire_event_{timeout,socket}.
1786 The existing blocking event handler, ZOOM_event, is a wrapper for the
1787 + blocking ZOOM_event_sys_{poll,select}.
1789 Implemented function ccl_xml_config which parses XML version of CCL
1790 configuration (bug #798).
1792 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1794 Added timings utility (yaz/timing.h)
1796 --- 2.1.44 2007/01/03
1798 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1801 Fixed bug #779: Rotation of apdu.log fails.
1803 Fixed for character set conversions:
1804 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1805 Honor G1 set in MARC-8 decoding.
1807 --- 2.1.42 2006/12/17
1809 Fixed bug #775: char conversion does not handle Alternative UTF-8
1812 Implemented function yaz_marc_read_line which parses MARC line format
1813 records. There is a wealth of formats out there. So far, this function
1814 reads line records produced by yaz_marc_write_line.
1816 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1817 more generic and easier to remember(!) options: -i format and -o format
1818 which specifies input format and output format respectively - where
1819 format is one of "marc", "marcxml", "line", "marcxchange".
1821 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1822 does not print anything except warnings for records.
1824 For yaz-marcdump, added support for MARC split into files (-s) with a given
1827 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1828 spec, at http://www.loc.gov/standards/sru/record-update/
1829 This has changed the binary layout of the following structs:
1830 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1831 bend_update_rr . Patch by Ko van der Sloot.
1833 Added GFS utility function bend_assoc_is_alive which returns 1 if
1834 association is still alive (client is connected); 0 otherwise (client
1835 closed connection). This allows busy servers to stop working for
1838 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1839 been a separate piece of software. This version of ziffy has been modified
1840 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1842 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1844 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1845 Client code may now interrogate options such as "init_opt_sort" to
1846 find out whether the server claims to support various options.
1848 --- 2.1.40 2006/11/27
1850 Added utilities yaz_{set,get}_esn to set/get element set name from
1853 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1854 of YAZ and has been so since YAZ 2.1.10.
1856 Implemented ZOOM_record_error which returns error information for
1857 record (surrogate diagnostic).
1859 --- 2.1.38 2006/10/31
1861 Updates for SRU Update by Ko van der Sloot:
1862 1. Changed name from "operation" to "action"
1863 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1864 versions in the code, marked as 'backward compatible'.
1865 3. Added diagnostics for SRU Update.
1867 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1869 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1871 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1873 For GFS, fixed problem with SRU diagnostic 'First record position out of
1874 range' being issued for 0 hits.
1876 zoomtst10 part of Windows Build.
1878 --- 2.1.36 2006/10/13
1880 Implemented yaz_filepath_comp which splits a path into file path
1881 components (required by Zebra 2.0.3+).
1883 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1884 BSD inspired license until now so this should not have any real impact on
1885 anybody. See http://www.opensource.org/licenses/bsd-license.php
1887 Fixed bug #687: Missing log lines.
1889 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1892 Fixed bug #689: SRU diagnostics to be added.
1894 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1895 whether a connection is idle (no more work do do).
1897 --- 2.1.34 2006/10/04
1899 Change type of optval from long to int for invocation of setsockopt with
1900 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1902 Added support for specifying the max log file size for the Generic
1903 Frontend Server. The size is given with option -r.
1905 --- 2.1.32 2006/09/21
1907 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1909 --- 2.1.30 2006/09/17
1911 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1914 Fixed bug in Generic Frontend Server that could cause a server to stop
1915 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1917 For the generic frontend server, the maximum record size is used as maximum
1918 size of incoming packages (SRU + Z39.50). The value until was previously
1919 only used in Z39.50 Init negotiation and, later, in a session controlled
1920 sizes of records returned. This is controlled using -k option. It can be
1921 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1923 --- 2.1.28 2006/09/04
1925 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1928 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1930 New option for yaz-marcdump -lpos=value which allows setting a portion
1931 of MARC header to a certain value.
1933 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1935 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1936 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1938 --- 2.1.26 2006/08/15
1940 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1943 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1945 --- 2.1.24 2006/08/08
1947 Fixed MARC ISO2709 encoding routines to deal with character set
1950 Minor changes to GFS logging. Database included in search request log
1953 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1954 cached/multiple records.
1956 Shared libraries are built by default on Unix+configure.
1958 Changed cql2pqf transformation to use a different evaluation order. The
1959 new order is: always, relation, structure, position, truncation, index
1960 and relationModifier. Old order was: always, relation, relationModifier,
1961 structure, index, position, truncation. Note that the the latter ones
1962 override former ones for identical attributes.. The new scheme means that
1963 it is possible to override any existing attribute with a relationModifier.
1964 And also that it is possible to override everything for the index rule
1965 (except the ones listed in relationModifier). No order is perfect but this
1966 one, we believe, covers more real cases.. The "always" should have been
1967 called "default", since the attributes there can be overridden with all
1970 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1971 compilation phase, but also for yaz-config --cflags output. This allows
1972 us to have public headers with Libxml2 stuff in them . It should also,
1973 eventually, make Libxml2 checks redundant in packages using YAZ, such
1976 --- 2.1.22 2006/06/15
1978 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1979 stored in uri, message and details.. Previously diagnostics were stored
1980 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1981 compatibility.. but he's probably the only one affected, so.
1983 Added support for CCL, compiled on the client side, in ZOOM-C. This
1984 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1985 input; the resulting query objects can be used for for searching with
1986 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1988 YAZ' configure searches for OpenSSL by default.
1990 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1991 SL_CTX_use_certificate_file. See
1992 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1993 for more info. Thanks to Ko van der Sloot.
1995 --- 2.1.20 2006/06/02
1997 Bug #600: SRU GET, POST support for yaz-client. Introduced
1998 command 'sru' which selects method SOAP/GET/POST.
2000 Allow missingValueAction to be specified for the sortspec string -
2001 function yaz_sort_spec. By default, the missing value action is null.
2002 Use ! to specify "abort". Use = followed by stringvalue to specify default
2005 Ensured that Present-handler (if defined) is called in GFS before any call to
2006 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2007 searchRetrieve requests.
2009 Documentation for YAZ is now based on the Docbook XML/XSLT using
2010 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2011 is no longer depending on jade/openjade or docbook-to-man scripts.
2012 PDF is no longer part of the distribution - but can optionally be
2013 made using DSSSL/jadetex or FOP.
2015 Added retrieval handling support in Generic Frontend Server to support
2016 conversion between MARC/XML as well as XSLTtransforms. See
2017 etc/yazgfs.xml for an example.
2019 Added Authentication support to Generic Frontend Server in SRU
2020 mode. Authentication using HTTP Basic is supported, as is the use
2021 of 'x-username' and 'x-password' parameters in the request itself.
2023 Added support for a new character set MARC8s identical to MARC8 except
2024 that it converts combined characters to single Unicode characters in the
2025 Latin-1 range (when possible).
2027 --- 2.1.18 2006/04/24
2029 ASN.1 compiler 0.4: generates brief Doxygen file header for
2030 generated .h/.c files.
2032 Utility yaz_iconv now supports conversion to MARC-8.
2034 New facilities for the MARC module. The reading - and writing of
2035 content are separate methods for the yaz_marc_t handle. The following
2036 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2037 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2038 format). Write functions have prefix yaz_marc_write_.. The existing
2039 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2040 available. Removed support for OAI-MARC and simplexml (not the
2041 simplexml from PHP5).
2043 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2044 to be returned for this connection.
2046 --- 2.1.16 2006/03/31
2048 Allow multiple languages and charsets to be specified with
2049 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2050 negcharset iso-8859-1,utf-8
2052 Translation of proximity nodes from CQL into PQF now works.
2054 Moved to automake 1.8, 1.9.
2056 Added function yaz_log_set_handler which allows a log handler to be
2057 installed. This handler will be called for all log messages. Output
2058 to file is also produced; but that can be disabled by passing NULL
2059 fname to yaz_log_init_file.
2061 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2063 For SRW (including GFS), accept application/soap+xml as content-type
2066 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2067 produces NO stylesheet reference even if a default stylesheet is specified
2070 --- 2.1.14 2006/03/14
2072 Updated Windows package to include yazd.dll + yazd.lib for the
2073 Development component.
2075 If the environment variable YAZ_LOG is set, then it is used as a
2076 string indicating the default level of logging to use if not
2077 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2078 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2079 used as before. So, for example, to omit warnings from YAZ logging,
2080 export YAZ_LOG=-warn
2082 cql_transform() now map structure and other attributes before indexes,
2083 so that index-specific structures and other attributes can override
2084 defaults. So now a combination of mapping specifications such as:
2086 index.dc.date = 1=date-modified 4=5
2087 does the right thing.
2089 cql_transform() now also respects the "always" mapping specification,
2090 which establishes an initial set of attributes to be used for all
2091 terms except where overridden by more specific attributes associated
2092 with the index, relation or modifier.
2094 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2095 which mode to use; one of "post", "get" or "soap" (SRW, default).
2097 Fixes for yaz_iconv routines: changed trie-based character set conversions
2098 to use only non-negative values for bit fields due to Sun's C compiler not
2099 supporting negative values.
2101 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2102 sequences where not read correctly. Fix by Rustam Usmanov.
2104 Updated win/makefile to use options, settings which makes things
2105 compile with VS C 2005.
2107 --- 2.1.12 2006/02/01
2109 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2111 In ZOOM socket code, use select instead of poll on MacOSX.
2113 ZOOM-C now support client-side compilation of CQL into RPN that is
2114 sent to the server, enabling CQL to be used against all Z39.50
2115 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2116 ZOOM_query object, and submit it using ZOOM_connection_search().
2117 The CQL-to-RPN translation uses a configuration file, the name of
2118 which must be specified in the Connection's "cqlfile" option.
2120 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2121 function, which takes as its start-term parameter a ZOOM_query object
2122 (which may have had either CQL or RPN set into it).
2125 --- 2.1.10 2005/11/29
2127 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2128 GFS to support this as well. Backend handler, bend_srw_update, does the
2129 update work. Code contributed by Ko van der Sloot.
2131 Allow retrieval of Search Result-1 information in ZOOM by the use of
2132 options that are attached to a result set. ZOOM documentation updated
2135 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2136 UTF-8 conversion. Patch by Raj Patel.
2138 Added option -m to GFS to control formatting of timestamps in log file.
2140 Added 'exit' as synonym for 'quit' in yaz-client
2142 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2143 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2144 for the new members. Patch by Ko van der Sloot.
2146 Added support for SRU POST. It is supported for content-type
2147 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2149 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2150 Instead make the library libyaz.la multi-threaded. Threading as a whole
2151 can still be disabled by configure option --disable-threads. Previosly,
2152 with older GLIBCs there were problems with MT libs under Apache. This
2153 has now been fixed a long time ago.
2155 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2158 CQL module modified to be case insensitive for relations/indexes/operations.
2160 Fixed bug in CQL transform code: incorrect value relationModifieder
2163 Added 'show all' command for yaz-client which retrieves all results
2166 Added new yaz-client, xmles, which takes a (private) OID and
2167 a document to be sent as an extended service request.
2169 Describe new yaz-client commands wait_response and set_auto_wait.
2171 Increase TCP/IP listener backlog from 3 (which I am guessing was
2172 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2173 that the socket will queue as many incoming connections as it's able
2174 to handle ongoing connections. In other words, it will never now
2175 refuse a connection that it would be able to handle merely because
2176 it's not got around to accepting() enough of the pending connections
2177 yet. This is the behaviour anyway under Linux, where the listen()
2178 argument is ignored; but not under BSD and on systems such as
2179 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2180 YAZ-based servers should now be uniform across operating systems in
2183 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2184 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2185 This allows yaz-marcdump to read large MARC batches (>2 GB).
2187 Modified all YAZ source files - except the source which is auto-generated
2188 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2191 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2192 corresponding to the existing *_setl() function. These allow option
2193 values containing arbitrary valuues.
2195 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2196 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2197 except that it returns an indicator of whether or not the sort
2198 criterion was accepted (0 for OK, -1 for invalid).
2200 --- 2.1.8 2005/06/07
2202 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2203 MARC output rather than returning "new" buffer.
2205 yaz-client warns about unknown init options.
2207 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2209 --- 2.1.6 2005/05/24
2211 Added support for SRW sort in Generic Frontend Server. Patch
2212 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2213 sortKeys - or NULL if none is provided.
2215 Fixed bug #307: It was impossible to specify indefinite/no timeout
2216 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2219 Added support for multiple languages and charsets to be specified in
2220 ZOOM. Each charset/language is separated by a blank. If negotiation is
2221 in effect in init-response, Option
2222 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2223 Code based on patch by Vasiliy Osadchuk.
2225 Fixed bug #306: infinite recursion that occurred when calling
2226 yaz_log_level_init as the first call (before other log level or
2229 Fixed bug in scan handling in front end server: if preferred-Position-In-
2230 Response was non-present, a NULL pointer referece was performed.
2232 --- 2.1.4 2005/04/26
2234 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2235 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2236 now defined for all those error codes. So instead of putting 109 in
2237 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2238 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2240 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2243 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2245 Program yaz-client now exits and produces an error message if multiple
2246 Z39.50 servers are specified on the command line (none or one allowed
2249 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2252 --- 2.1.2 2005/03/16
2254 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2256 Fixed bug #272: Preserve spacing for CCL terms.
2258 --- 2.1.0 2005/03/14
2260 Added support for virtual hosts and multiple backend servers for
2261 the YAZ frontend server. The configution is XML based and
2262 support specificition of CQL to RPN mappings and explain information.
2263 See section "Virtual Hosts" in the YAZ manual.
2265 Extended OPAC display utility. OPAC display utility renders
2266 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2267 to supplement yaz_marc_decode_wrbuf.
2269 Fixed a bug in MARC decoder that could caused it to crash for some
2270 invalid MARC records. More diagnostics and warnings where added in
2271 XML output (warnings, etc are stored in comments).
2273 --- 2.0.34 2005/02/08
2275 Fixes for UNIX domain sockets. Bug #261.
2277 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2279 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2280 Added yaz_marc_subfield_str which defines subfield lead string which is
2281 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2282 yaz_marc_endline_str which defines end of fields string used in
2283 YAZ_MARC_LINE format. Default string is newline.
2285 Experimental support for MarcXChange. This format can be produced
2286 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2287 http://www.bs.dk/standards/MarcXchange.xsd
2289 Added yaz-client commands scansize that sets maximum number of
2290 entries to be returned by scan.
2292 --- 2.0.32 2005/01/11
2294 Added support for SRW scan in yaz-client and Generic Frontend Server.
2296 * Added whereInList member to SRW Scan Term.
2298 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2300 Fixed NMEM system to return aligned blocks on the smallest boundaries
2301 that are suitably aligned for all possible types on the particular
2302 architecture YAZ is being built for.
2304 --- 2.0.30 2005/01/04
2306 Fixed numerious warnings that was issued with newer versions of GCC.
2308 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2309 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2312 Make YAZ Generic Frontend Server slightly faster.
2314 Enhance (and reduce) logging for Generic Frontend Server.
2316 Revert YAZ log system so that it flushes every write operation
2317 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2319 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2320 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2321 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2322 will effectively disable old definitions.
2324 --- 2.0.28 2004/11/09
2326 Added yaz_log_time_format which specifies log format using
2329 Added yaz_log_module_level which returns mask for a module. Value
2330 is non-zero mask a if module is enabled; zero if disabled.
2332 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2333 in include/yaz/cql.h.
2335 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2337 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2339 Fixed bug #172: RPM builds does not enable SSL.
2341 Doxyfile.in part of dist. Doxyfile generated by configure.
2343 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2344 are given and the corresponding component does not exist.
2346 Extend CCL documentation in YAZ reference. Describe r=r.
2348 --- 2.0.26 2004/10/01
2350 Fixed MARC->MARCXML conversion to properly deal with
2351 fields, subfields, indicators having non-ASCII characters.
2353 Fixed MARC->MARCXML conversion so that ASCII control characters
2354 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2357 Added YAZ GFS support for conversion from Z39.50 surrogate
2358 diagnostics to SRW surrogate diagnostics.
2360 Bug fix: YAZ GFS did not return schema in explainResponse.
2362 --- 2.0.25 2004/09/30
2364 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2365 now converts recordSchema to elementSetName as well as schema URI.
2367 Fixed bug in COMSTACK that prevented HTTP request packages from being
2370 --- 2.0.24 2004/09/29
2372 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2373 does not require white-space before and after the dash in a range, e.g.
2374 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2377 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2378 due to new GCC removing "redundant" code.
2380 Added yaz-client commands scanpos and scanstep that sets preferred
2381 position and step-size for scan.
2383 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2385 Added CCL utility ccl_qual_buf which parses one or more CCL
2386 spec lines in a buffer.
2388 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2389 of name and value - ignoring empty lines and comments.
2391 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2393 Added odr_get_element_path which returns current element path for an
2394 ODR handle. This utility is useful in error handling or user-defined
2397 Added ODR_PRINT utility odr_set_stream which is is a more generic
2398 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2399 to a write function and pointer to close function. The close function - if
2400 non-NULL - will be called during odr_destroy.
2402 Fixed bug in CCL parser where truncation char was not removed from
2403 right side when truncation=both was in effect.
2405 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2408 --- 2.0.23 2004/08/11
2410 Fix buffer overrun in CQL parser when dealing with proximity (%).
2412 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2413 to UTF-8/UCS conversion is now only based on codetables.xml.
2415 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2417 --- 2.0.22 2004/08/06
2419 Add support for more "commit changes" in ZOOM (uses Extended Services).
2421 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2424 Yet another small fix for configure of SSL.
2426 --- 2.0.21 2004/05/14
2428 Fix SSL libs for configure when --with-openssl=DIR is given.
2430 --- 2.0.20 2004/05/10
2432 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2434 SSL comstack now uses yaz.pem certificate file on server side
2435 by default. Certificate filename can be configured by calling
2436 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2438 Fix bug regarding multiple calls to ZOOM_connection_connect.
2440 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2442 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2443 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2445 ZOOM now allows inspection of X509 peer certificate for verification.
2446 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2448 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2449 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2450 as "modular" but it simplifies things.
2452 Added cs_get_peer_certificate to that returns peer X509 PEM.
2454 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2455 NULL if SSL is unavailable.
2457 Documentation about MARC decoding tools.
2459 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2461 --- 2.0.19 2004/03/30
2463 Rename CHANGELOG to NEWS to follow GNU style packing.
2465 Fix bug with missing initialization of member in init_diagnostics.
2466 This bug affects threaded version of GFS server.
2468 --- 2.0.18 2004/03/20
2470 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2473 Ensure zlib.dll is packed with Windows install.
2475 --- 2.0.17 2004/03/17
2477 Fix encoding of xsd:string to use text instead of CDATA.
2479 Fix endless loop in CQL parser with unbalanced ".
2481 Use a more compact way to store MARC-8 conversion tables.
2483 --- 2.0.16 2004/03/16 Debian only
2485 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2488 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2493 --- 2.0.15 2004/03/01
2495 Another fix for decoding of XML packed records.
2497 --- 2.0.14 2004/02/25
2499 Fixes for Chunked encoding. White space not ignored after length spec.
2501 Update NS and use default NS for SRW diagnostic elements.
2503 --- 2.0.13 2004/02/23
2505 Implement ZOOM_resultset_cache_reset which resets record cache.
2507 Implement ZOOM_resultset_sort which sorts a result set.
2509 Implement chunked HTTP transfer.
2511 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2513 --- 2.0.12 2004/02/16
2515 Added member 'schema' to bend_explain_rr structure so that backend
2516 can specify explain record identifier. Defaults to Zeerex 2.0.
2518 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2520 --- 2.0.11 2004/02/16
2522 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2525 Added init command for yaz-client which sends "extra" init request.
2527 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2528 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2530 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2532 Make ZOOM error code for "invalid query".
2534 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2536 --- 2.0.10 2004/02/05
2538 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2541 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2543 Added option -p <file> to make Generic Frontend Server to write PID file.
2545 Added option -D to put Generic Frontend Server in background on its own.
2547 Make ZOOM C recognize option "password". If unset, "pass" is used
2548 (for backwards compatibility).
2550 Fixed a bug in Generic Frontend Server that could make it crash if a
2551 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2554 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2555 Must be issued before open, in order to be in effect.
2557 --- 2.0.9-6 2004/01/12 Debian/Windows
2559 Make the SRU server more picky WRT unknown params, etc.
2561 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2563 New YAZ client command, options, that sets Z39.50 options.
2565 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2566 options from a string of tokens (one token for each option bit).
2568 Update SRW diagnostic code messages.
2570 --- 2.0.9-5 2004/01/07 Debian/Windows
2572 Handle user defined stylesheet for SRW/SRU.
2574 --- 2.0.9-4 2004/01/06 Debian/Windows
2576 Fix bug in decoding of Content-Length.
2578 --- 2.0.9-3 2004/01/06 Debian/Windows
2580 Fix a bug with decoding of XML packed records.
2582 --- 2.0.9-2 2004/01/05 Debian only
2584 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2586 Fix bug in SRW/SRU diagnostics decoding.
2588 --- 2.0.9 2004/01/05
2590 Fixed bug in Generic Frontend Server which could drop records exceeding
2591 preferred message size. Reported and fixed by Irina Dijour.
2593 Fixed calculation of package size for structured records in Generic
2594 Frontend Server. Reported and fixed by Irina Dijour.
2596 Fixed namespace for SRW/SRU diagnostics.
2598 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2600 --- 2.0.8 2003/12/22
2602 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2603 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2606 CQL changes to reflect recent changes to the specification:
2607 * Documentation talks about context sets instead of index sets.
2608 * Documentation talks about indexes instead of qualifiers.
2609 * The CQL-to-PQF transformer's configuration file now uses
2610 "index.set.name = <attributes>" instead of the old form
2611 "qualifier.set.name = <attributes>". (Both forms are still
2612 understood but the latter is deprecated.)
2613 * CQL terms with no explicit index specified are now interpreted as
2614 cql.serverChoice instead of srw.serverChoice (which of course
2615 behaves exactly the same.)
2617 --- 2.0.7 2003/12/16
2619 MARC conversion can now generate ISO2709 output in another
2620 character set. yaz-marcdump uses this facility if you invoke it
2623 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2624 functions from there can be used from C++.
2626 --- 2.0.6 2003/12/04
2628 Frontend server now transfers memory from decoded packages to stream
2631 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2632 references to show up.
2634 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2635 the ZOOM Abstract API. The older names for the same options are still
2636 also supported for the benefit of old applications.
2638 ZOOM-C supports "implementationId" and "implementationVersion" options
2639 to go along with "implementationName". These allow the user code to
2640 specify identification strings to be sent to servers.
2641 Add OID for the new ExtLite attribute set.
2643 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2644 as requested/supplid by Ere Maijala <ere@atp.fi>
2646 For generic frontend server, reverse the order of
2647 "toolkit-supplied / application-supplied" strings sent as implementationId,
2648 Name and Version. Also, remove the spaces around the slash. This brings
2649 the GFS in line with the behaviour of ZOOM-C on the client side.
2651 Add function ZOOM_scanset_display_term.
2653 yaz-client shows scan displayTerm if present.
2655 Utility yaz-iconv is now installed by default along with the man page
2658 Extend configure check for OpenSSL to use pkg-config where available (such
2661 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2662 server to specify uid/gid/mask for socket using the format
2663 unix:[user=uid,][group=gid,][umask=mask,]file=path
2664 If file= is omitted the existing format is assumed, e.g.
2666 in which case the mask is 0666 (rw for everybody).
2668 Major restructure of YAZ source. All source in libyaz is in src directory.
2669 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2670 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2672 Added man page for utility yaz-marcdump (used to be called marcdump).
2673 yaz-marcdump is installed by 'make install'.
2675 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2676 of incoming package failed.
2678 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2680 Change prototype of odr_perror: add const to message string.
2682 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2684 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2685 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2686 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2687 DNS lookup. There should not be any compatibility problems with this
2688 assuming that blocking=1 or 0 is used.
2690 Fix bad reference in UNIX comstack in function cs_addrstr.
2692 Fix for compilation on AIX.
2694 The generic front-end server (server/seshigh.c) now supports returning
2695 Init diagnostics to the client in User-information-field, in
2696 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2699 --- 2.0.4 2003/09/04
2701 Allow any CQL relation (not just all,any,exact,scr).
2703 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2704 that features the same UI.
2706 Implemented command update0 in YAZ client which is equivalent to
2707 update but uses old of Ext Update ASN.1.
2709 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2710 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2711 Previously no OID was used for this info.
2713 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2714 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2715 returns 'malformed search term' otherwise.
2717 SortResponse member resultCount now set to NULL in sort handler of
2720 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2723 Add three new utility functions for translating OIDs between various
2724 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2725 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2726 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2727 char *oid_to_dotstring(const int *oid, char *oidbuf);
2728 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2730 Reverted modifications for ES Update definition for z_IU0Update
2731 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2732 is back to YAZ 2.0.2.
2734 String value attributes for CCL parser.
2736 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2737 which their FirstSearch server returns in Init responses, sometimes
2738 carrying useful diagnostic information when Init fails. This has the
2739 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2740 "z39.50/oclcui.asn", where its definition is somewhat different from
2741 what OCLC document on their web-site, as required to interoperate with
2744 Support for anonymous authentication in yaz-client. Use the command
2747 * Fix the OID of the Index Data-local "admin" Extended Service from
2748 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2749 the 1000, which indicates a locally-defined OID, was a mistake.
2751 --- 2.0.3 2003/06/20
2753 Fix CCL directive @case handling so that it affects string match for
2754 both CCL keywords and qualifiers.
2756 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2757 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2758 Decoder has been updated with ASN.1 changes as listed in
2759 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2760 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2761 z_IUUpdate, remains unchanged.
2763 ZOOM_record_get may now return a record in a specific character set.
2764 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2765 "from" is the character set of record as returned by target. "to" is
2766 the character set to be returned. If omitted, "to" is UTF-8.
2768 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2770 New ODR utility, odr_getelement, which returns name of element for
2771 which encoding/decoding failed.
2773 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2774 in cases where a required element was omitted.
2776 Bug fix: some MARC8 sequences were not converted.
2778 New ZOOM option "step" which specifies number of records to be
2779 retrieved in one chunk. Used in conjunction with "start" and "count".
2781 SRW support for yaz-client. Use scheme http: to use it, e.g.
2784 yaz-client no longer does (un)intelligent character set conversions
2785 by default. Can be enabled with charset and marc_charset commands.
2787 xmalloc trace fix for 64-bit systems such as DEC alpha.
2789 Solaris 2.6 compile fix.
2791 New function, cql_strerror() translates SRW error codes, as returned
2792 by cql_transform_error(), into human-readable English strings. Used
2793 in yaz-client diagnostics when appropriate.
2795 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2796 converts it into a type-1 query which is sent to the server. This
2797 makes CQL available for use with all Z-servers, as opposed to the tiny
2798 minority that can handle CQL queries themselves.
2800 --- 2.0.2 2003/04/28
2802 New Debian package layout similar to the Redhat Package layout.
2804 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2805 and search result respectively.
2807 --- 2.0.1 2003/04/25
2809 Redhat package is now several packages: libyaz (runtime libraries),
2810 libyaz-devel (development and documentation, and yaz (utility programs).
2811 Package spec file by Morten Bogeskov.
2813 New member 'schema' in struct bend_fetch_rr which the name of requested
2814 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2815 handler MAY set this to reflect the schema of the returned record.
2817 New member 'display_term' in struct scan_entry. GFS now sets member entries
2818 and allocates scan entries to be filled by user scan handler. In previous
2819 version, entries member was allocated by the scan handler. That still works,
2820 but the GFS will ignore member display_term - assuming it was NOT set by
2821 the handler. The fact that the GFS now allocates the entries both allows
2822 for new members and makes a scan handler easier to write.
2824 Fix CQL lex buffer overflow.
2826 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2827 SRU default recordPacking is string.
2829 SRU protocol support for frontend server.
2831 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2833 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2835 Added scan for the ZOOM shell (zoomsh).
2839 * String Identifers for Schemas (Amendment 5).
2840 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2841 Old definition for schema
2842 Odr_oid *schema; /* OPT */
2847 Z_InternationalString *uri;
2848 #define Z_Schema_oid 1
2849 #define Z_Schema_uri 2
2852 * resultCount parameter to Sort Response (Amendment 1).
2853 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2855 Support for SRW 1.0 over HTTP. This is an optional feature and
2856 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2859 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2860 on the same port. SRW SearchRetrieveRequests are mapped
2861 to bend_init,bend_search,bend_fetch,bend_close.
2863 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2865 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2866 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2868 ZOOM connections are SRW based if schem http is used for hostname
2869 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2870 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2872 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2873 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2874 distance=n, order=true/false, relation=le, prox unit=word. If
2875 n is omitted, distance 1 is used.
2877 Fixed problem with C compiler include path in wrong order.
2879 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2880 on Solaris. Patch from Ko van der Sloot.
2882 New MARC decode API. All new functions operate on a yaz_marc_t
2883 handle. The most important new functions are: yaz_marc_create,
2884 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2885 decode and destroy respectively. Decoder can produce formats
2886 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2887 include/yaz/marcdisp.h.
2889 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2890 to UTF-8, UCS-32, wchar_t or Latin-1.
2892 * Prototypes for yaz_iconv_-functions moved to separate header
2893 include/yaz/yaz-iconv.h.
2895 Make a few private functions 'static' in unix.c. This prevents
2896 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2898 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2899 are set when Init Response is received.
2901 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2902 but returns diagnostic set as well.
2904 New function yaz_strerror which is a portable wrapper for
2905 strerror/strerror_r/GetLastMessage.
2907 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2908 is returned for MARC. If type is "oai", then OAI MARC is returned.
2910 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2913 --- 1.9.2 2002/11/26
2915 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2917 Fix bad race conditions on SIGTERM and terminate gracefully in
2920 Move retrieval (data1) module to Zebra since nobody seems to be
2923 Add GRS-1 render for ZOOM using same format as yaz-client.
2925 --- 1.9.1 2002/10/05
2927 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2929 Fix broken ESpec handling in data1 module.
2931 SGML reader parses comments and makes them part of the data1 tree.
2933 Added several type casts so that YAZ compiles as C++ code.
2935 ZOOM didn't handle PDU encoding failures properly.
2937 Added more Bib-1 diagnostics (approved extensions).
2939 GNU configure: better check for iconv.
2941 More portable use of accept, getpeername. Check for socklen_t. Use
2942 int/size_t if socklen_t is not defined.
2946 PQF parser rejects bad queries - including those with extra
2947 characters in them. PQF parser used to silently ignore that.
2948 Cleaner API for PQF added, which allows you to get detailed
2949 error information for bad queries (see yaz/pquery.h).
2951 Fixed bug in ZOOM_record_get for type "database".
2953 Implemented mini iconv library supporting conversions between
2954 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2956 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2958 --- 1.8.9 2002/08/20
2960 Fixed ZOOM C record cache so that preferredRecordSyntax and
2961 elementSetName is used to check for already fetched records.
2963 --- 1.8.8 2002/08/02
2965 Added three members in bend_initrequest structure to facilitate
2966 character set negotiation.
2968 Fixed a bug in frontend server that could cause indefinite
2969 loops under rare conditions.
2971 Revised character set utilities (charneg.h) so that encoding
2972 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2974 For PQF, directive @term <type> sets term type for Scan/Search.
2975 Here <type> is general, string, numeric, null. The term type
2976 is inherited - just like @attr.
2978 New call odr_set_charset that sets character set conversion for
2979 international-strings on a ODR stream. Prototype is:
2980 int odr_set_charset(ODR o, const char *to, const char *from);
2981 The InternationalString is still represented as C string in YAZ
2982 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2983 won't). On the protocol level, you can use any encoding.
2985 Support for UNIX sockets in ZOOM.
2987 Solaris recv sometimes returns errno == ENOENT. It is treated as
2988 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2990 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2991 both client and server. Code by Morten Bogeskov.
2993 --- 1.8.7 2002/05/22
2995 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2996 that they can be used directly from Visual Basic. You must recompile
2997 your windows APP if you're using ZOOM.
2999 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3000 Commands "lang" and "charset" sets language and character set respectively.
3001 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3002 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3004 Attributes from multiple CCL fields may be OR'ed rather than merged
3005 using directive "@field or". Fields are still merged by default -
3006 equivalent to "@field merge".
3008 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3011 Fixed bug in zget for parameter ExtendedServicesResponse.
3015 --- 1.8.6 2002/03/25
3017 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3019 Client displays USR.1:SearchResult-1 (hits per term).
3021 Additional Search Info for search in Generic Frontend Server.
3023 Fixed CCL parsing of "field=s".
3025 WIN32 installer - using the excellent NSIS software from nullsoft.
3027 Fixed CCL parsing of "field = - <number>".
3029 Added function yaz_marc_decode that decodes MARC for line mode
3030 display or XML (similar to that used by JZKit).
3032 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3033 Z39.50. But ISO/ILL was, however.
3035 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3036 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3041 --- 1.8.5 2002/02/03
3043 New YAZ client features: Command completion and new commands:
3044 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3045 Code provided by Jacob Poulsen.
3047 New call oid_trav, that visits all registered OIDs via callback.
3049 Function ZOOM_record_get now returns const char pointer rather than
3050 void pointer. It saves a lot of type casts.
3052 For YAZ client, command "auth" now allows you to set authentication
3053 in IdPass style. It is enabled when three tokens are given - order
3054 is user, group and password.
3056 Fix memory leaks in MARC record handling for ZOOM.
3058 New option for YAZ client, -k <kilobytes> that sets
3059 maximum record size. Similar to -k option for generic frontend
3060 server and yaz-ztest.
3062 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3064 Prefix query parser reports "fail" when bad attribute set is given.
3066 Fix in MARC decoder. Proximity logging. Fix for attribute set
3067 in scan handler for server. Patches by Shigeru Ishida.
3069 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3072 Configure option --with-openssl=<dir> now works when a directory is
3073 specified. Patch provided by Morten Bogeskov.
3075 New option for YAZ client, -u <auth>, that sets authentication.
3077 ZOOM fix: error information was sometimes "missing", since error
3078 was cleared/reset too when it shouldn't.
3080 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3082 --- 1.8.4 2002/01/04
3084 Scan for ZOOM API. New object ZOOM_scanset. New functions
3085 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3086 ZOOM_scanset_destroy.
3088 New ZOOM function, ZOOM_connection_last_event, that returns type
3089 of last event (such as "receive data", "send data", "apdu received",
3092 New ZOOM option, schema, that specifies schema for retrieval.
3094 New CCL feature. Qualifiers can be aliases for one or more
3095 other qualifiers (if more than one is given, OR is used).
3097 ZOOM uses named result sets if target supports it.
3099 Two new YAZ client commands: . (dot, which sources a script of YAZ
3100 client commands), and ! (to execute shell command.). Implemented
3103 Working on Debian packages.
3105 --- 1.8.3 2001/11/19
3107 YAZ client enables named result sets only if target supports it.
3109 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3111 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3112 with key="host" to get same result.
3114 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3115 Function Z3950_resultset_record(s) returns references to records
3116 "owned" by resultset. To become owner use Z3950_record_clone.
3118 Function z_ext_record handles Extended Services. Thanks to
3121 --- 1.8.2 2001/11/12
3123 CCL Parser fix: ignore token comma when dealing with and-lists.
3125 Documentation updates for COMSTACK.
3127 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3128 Changed prototype Z3950_records. For some functions, int parameters
3129 were changed to size_t.
3131 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3134 New MARC decode/display function, marc_display_exl, which properly rejects
3135 non-ISO2709 records. YAZ client uses it.
3137 --- 1.8.1 2001/10/29
3139 Fix bug: local attribute set wasn't set correctly in PQF strings.
3143 * Old Z39.50 codecs no longer supported.
3145 Added ZOOM C binding. See http://zoom.z3950.org/
3147 Renamed states for COMSTACKs to avoid confusion with events.
3149 Implemented cs_look and proper cs_rcvconnect.
3151 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3153 Configure detects POSIX threads on OpenBSD.
3155 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3156 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3158 When error is returned from present handler, non-surrogate diagnostic
3159 is returned in present response (and fetch handler is no longer called).
3161 * Minor adjustments to pquery parser (PQF). Token characters may be
3162 escaped by using backslash (C-style).
3164 PQF parser allows string attribute values to be specified. For @attr,
3165 non-numeric characters after the equal-sign are treated as strings
3166 (e.g. @attr 9=title).
3168 CCL trunction character may be defined (@truncation in file)
3170 * function zget_ExtendedServicesRequest sets waitAction to
3171 waitIfPossible (was wait).
3173 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3176 CCL operator names may be set in field definition files (CCL_bibset).
3177 See ccl/bib1 for an example.
3179 Fixes in ASN.1 compiler for C++ compatibility.
3181 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3182 and "op_or" to avoid conflict with C++.
3184 Fixed problem with GNU readline detection on Redhat 7.0.
3186 Added step-size for Scan backend handler.
3188 Fixed bug that made the frontend server crash when no attribute
3189 set was specified for scan.
3191 Front-end server automatically switches to original working directory
3192 when installed as an NT service. Previously -w had to be specified to
3195 Added extended attributes for retrieval module (data1), so that data1
3196 records carry d1_readXML/SGML attributes. d1_read also supports
3197 null-data rules ( <tag/>)
3199 On UNIX when POSIX threads are available, a separate library libyazthread
3200 is created. Programmers should link with that library and the yaz library
3201 when using threads. The reason for the split was that some applications
3202 on Linux, such as Apache, doesn't work well when using shared objects that
3205 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3206 (or any frontend server) in SSL mode by specifying ssl: followed by
3207 address. Only tested on UNIX.
3209 Added feature for CCL module. Virtual structure s=al or s=ol generates
3210 and-list and or-list respectively instead of phrase search.
3214 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3215 log_mask_str. This was done to avoid name conflicts with other libraries
3216 (such as other PHP extensions).
3218 Added raw OID member for preferred record syntax (request_format_raw)
3219 and returned record syntax (output_format_raw) for backend fetch method.
3221 Config file yaz-config now accepts options so that it returns specific
3222 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3224 Shared library support for UNIX using GNU libtool.
3226 * Modified backend interface. Request/Response struct's replaced by
3227 one read/write C struct. For example bend_fetchrequest and
3228 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3229 Every handler - even search has to be registered in bend_init
3230 handler. This means that the YAZ library no longer refers to
3231 external functions and it makes it possible to make the whole
3232 thing a single DLL/SO.
3234 Added Segment handler for backend server.
3236 Added Zmbol/Zebra administrative functions to YAZ client.
3238 Threaded frontend server on UNIX (when POSIX Threads are available).
3239 Starting the server with option -T enables multi-threading.
3243 Added configure option --enable-comp/disable-comp to control use
3244 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3245 located in sub directory asn.
3247 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3248 in ${exec_prefix}/bin along with the other programs yaz-client and
3251 GNU automake used to maintain makefiles.
3253 Added several OID's.
3255 Changed retrieval module so that we can load records with no abstract
3256 syntax defined. Tagpaths in these records are fully composed of string
3259 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3263 On UNIX, the generated makefile now supports a proper 'make install'.
3264 The prefix can be set via GNU configure to set the install location
3265 (default is /usr/local).
3267 * YAZ programs client and ztest were renamed to yaz-client and
3268 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3269 locations, such as /usr/bin,/usr/local/bin,etc.
3271 * YAZ Header files were moved from include to include/yaz. YAZ Header
3272 files are referred to as include <yaz/log.h> rather than <log.h>.
3273 The YAZ include path (-I ..) is therefore the same as before. Programmers
3274 should update their #include statements or use -Ipath/include/yaz
3275 instead. The main motivation for doing this change is that YAZ header files
3276 can be installed in "standard" locations /usr/include,/usr/local/include
3277 without introducing conflicts, since ALL YAZ header files are stored
3278 in subdirectory yaz (under /usr/include for example).
3280 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3281 rather than project/workspace files. We switched because project files
3282 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3285 Changed name of logging function, logf, to yaz_log, to prevent name
3286 clash with some math-log functions. The YAZ header log.h defines logf
3287 to yaz_log (#define) so there should be no incompatibilities by this
3290 Added bend_start/bend_stop handlers for server. These handler are
3291 called on start/stop of server. For windows they are called whenever
3292 a service is started/stopped.
3294 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3295 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3296 in util/yc.tcl. The auto-generated C code structures are, in a few
3297 cases, incompatible with the old decoders. There are differences in the
3298 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3299 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3300 The preprocessor variable ASN_COMPILED is defined when the compiled
3301 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3302 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3303 wish to use the old encoders/decoders you can specify --disable-yc
3306 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3307 version so that it supports both new - and old version of DB Update
3309 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3310 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3311 change. The name parameter can be set to 0 in which no name is specified
3312 for the construction. The macros odr_implicit and odr_explicit sets name
3313 parameter to zero for the construction involved. New macros
3314 odr_implicit_tag and odr_explicit_tag are similar to the others,
3315 except that a name parameter is added. For programmers' that don't use
3316 ODR they probably only need to change the call to z_APDU and z_External.
3318 Added access control facility by interfacing the TCP wrapper library.
3319 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3320 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3321 name of the daemon and enables the access control as specified in
3322 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3324 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3325 den Dool <H.M.vdnDool@kub.nl>.
3327 Added reference ID parameter to most functions in server API - refer
3328 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3330 Changed name of ccl library to libccl.a (was ccl.a).
3332 Fixed bug in decoder for Explain (Category TargetInfo).
3334 Added support for GNU readline in client. Thanks to Jacob Poulsen
3335 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3337 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3338 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3339 IMPLEMENTATION! This change was made to the development version before
3340 the ZIG decided to retract the amendment. If any users MUST be
3341 compatible with the original Update definition, PLEASE CONTACT US, and
3342 we will include a separate definition corresponding to the old Update
3343 ES. Note that because of the change to the ASN.1 of the
3344 TaskPackageRecordStructure we cannot define a single structure that
3345 will support both versions.
3347 * Added const modifier to buffer parameter for some ODR/BER encoding
3348 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3349 completeWAIS, odr_dumpBER.
3351 Fixed bug in client.c which caused a crash when a scanResponse didn't
3352 contain positionOfTerm.
3354 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3355 * will cause an error in a client if a non-YAZ target sends both a
3356 * list of Scan entries and non-surrogate diagnostics.
3358 Retrieval module enhancements. Tag sets may be typed in the reference
3359 to it. From the .abs-file the "tagset" directive takes a third optional
3360 integer type for the tag set referenced. From a .tag-file the "include"
3361 directive takes a third optional type as well. The old "type" directive
3362 in the tag set itself is still recognized but acts as the default type
3365 Backend interface change. Individual Scan terms returned from bend_scan
3366 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3367 in include/backend.h.
3369 Retrieval module enhancements. Multiple tag sets and attribute sets may
3370 be specified in abstract syntax specs. Revised the error/warning for
3371 logging messages reported by the retrieval module when reading the
3374 Object Identifier system (oid_..) changed. The API is backwards
3375 compatible but the oid-routines now allocates new OID's when needed.
3376 Raw OID's may be specified in oid_getvalbyname.
3378 YAZ now uses GNU configure to generate Makefile(s).
3380 * Minor changes in some of the member names of DeleteResultSetRequest and
3381 DeleteResultSetResponse. See include/proto.h.
3383 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3384 and added member 'languages' in TargetInfo (which was missing).
3386 Changed the way attribute sets are handled in the retrieval
3387 module. These are now cached, just like the abstract syntaxes
3390 Changed YAZ so that it links with compiled ASN.1.
3392 Added Explain-schema definitions and mapping routines. The following
3393 Explain categories have been implemented: AttributeDetails,
3394 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3396 Fixed minor bug in Windows version of Server Library.
3398 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3400 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3402 Added EXTERNAL: UNIverse Resource Report (non-standard).
3404 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3405 ENUMERATED and SET OF.
3407 * Added 'const' to some of the char pointer arguments for the
3408 functions, data1_read_node, data1_getelementbytagname,
3409 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3412 Fixed bug in data1_insert_taggeddata - the last_child member of
3413 parent wasn't initialised.
3415 * Changed data1_read_record and data1_read_node so that the supplied
3416 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3417 doesn't refer to any parts of the "SGML"-buffer.
3419 Fixed bug in server library (Windows version of statserv_remove).
3421 * Changed code so that it compiles as C++. The type definition
3422 of Odr_fun which is a member of Odr_arm was changed. The result is,
3423 that an explicit typecast is needed for the fun pointer when
3424 using Odr_arm - as in:
3425 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3427 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3429 Implemented the new structured date and time definition as approved
3430 by the ZIG. Added schemaId element to the specificTag in Espec-1
3431 (also approved at the last ZIG). Thanks to RVDM.
3433 Added some Object identifiers (RVDM).
3435 Changed the Update Extended Service (RVDM).
3437 Added command "refid" to client which specifies referenceId for
3438 the following requests.
3440 Implemented extended service handling for server. See ztest.c
3441 for an example as well as backend.h. New handlers are registerd
3442 in the Init handler.
3444 * Changed interface for sort in server.
3446 Added new members to statserv_options_block. It allows a server
3447 to read options from another source than just the command line. Thanks
3448 to Charles Woodfield.
3450 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3451 renamed to zboolean. Some C++ compilers complained about the name.
3453 Minor changes to gils.abs. Added index 's' (sort) on title
3454 and date/time-last-modified.
3456 --- 1.4pl2 1998/1/30
3458 Fixed bug in server library regarding inetd mode (-i). This bug
3459 was introduced by release 1.4.
3461 --- 1.4pl1 1998/1/29
3463 Added sort facility in client and backend server interface.
3465 Fixed problem with dependencies in Makefile(s).
3467 Fixed bugs for encoders/decoders of extended services and
3470 Implemented sub-tree feature for schemas. Sub-trees are
3471 referenced in *.abs-files. See explain.abs for an example
3472 of the use of this feature.
3474 Modified bib1.att; local attributes for ANY didn't include
3475 ANY itself (only affects use of the retrieval module).
3477 Fixed bug in plain SGML reader in function data1_read_node:
3478 tags with prefix "var" was incorrectly interpreted as variants.
3480 Added feature "sub-schemas" to enable references to - and definitions
3481 of - group of elements.
3483 * Removed member parent from type data1_element (in data1.h).
3485 Implemented function odr_nullval() that returns the value of
3488 * Removed member num_children from data1_node (in data1.h).
3490 Made NT service interface part of the server library. The
3491 function statserv_main uses the NT service when required and
3492 calls the statserv_start / statserv_close routines.
3494 Routine zget_SearchRequest and zget_PresentRequest fills
3495 resultSetName/Id member with "default" instead of "Default".
3497 Fixed memory leak in server. Request queue member wasn't freed.
3499 Fixed nmem_exit so that memory is freed.
3503 Revised the CCL parser utility to be thread safe.
3505 Added function, oid_ent_to_oid, to replace the function
3506 oid_getoidbyent, which is not thread safe.
3508 * Added nmem_init and nmem_exit to initialize and release
3509 NMEM resources. Function nmem_init should be called once in the
3510 initial thread before NMEM/ODR is used. statserv.c and client.c
3511 have been changed accordingly. The change was necessary to make
3512 NMEM thread safe. The NMEM memory pool is shared amongst threads
3513 in a process. Unix-based applications will still work fine without
3516 Added NT Services interface for the the Z39.50 (statserv) Server.
3517 Refer to the ztest.c source on the usage.
3519 Windows 95/NT port using MSVC5.0. Project files are included in the
3522 * Defined new 'global' handle for the retrieval (data1) system. The
3523 new handled, data1_handle, describes the state of the data1 system.
3524 This handle is passed as first argument to virtually all
3525 data1 related routines. The functions data1_create and data1_destroy
3526 creates and destroys a data1 handle respectively.
3528 Added ODR encode stream member to all backend request structures
3529 init, search, scan etc. This stream should be used to allocate all
3530 memory used for the response when thread safe operation is needed.
3532 Changed the comstack utility, cs_addstr, to be thread safe. The
3533 returned hostname string returned by the function is now part the
3536 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3537 function. The cs_straddr takes a COMSTACK handle as argument, so this
3538 function must be used after cs_create and before bind/connect.
3539 This function is thread safe.
3541 Moved test server to 'ztest' directory - generic server code still
3542 in 'server' directory.
3544 Made prefix query (pquery.c) utility thread safe.
3546 Added new function modifier YAZ_EXPORT to 'export' public DLL
3547 functions when using windows (see include/yconfig.h).
3549 Added definitions to the OID database (util/oid.c) (RVDM).
3551 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3553 Added call to ccl_rpn_delete in client program.
3555 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3556 release of RPN structure.
3558 Added support for C++, headers uses extern "C" for public definitions.
3559 With input from RVDM.
3561 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3562 Thanks to Ronald van der Meer (RVDM).
3564 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3566 Added support for private extensions to the OID database
3567 (oid_setprivateoids()). Thanks to RVDM.
3569 Added optional, physical ANY (key replication)
3571 Fixed null-reference problem in GRS-1 output filter.
3573 Proximity operator added to Prefix Query Format (PQF).
3575 In test client command "base" accepts multiple databases.
3577 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3581 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3583 Smallish bug-fixes in the new encoders/decoders (explain).
3585 Bug fixed in DeleteRequest.
3587 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3589 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3591 Added SOIF syntax (using private OID for now) to retrieval module and client.
3593 Added Update extended service.
3595 Added SearchResult-1 additional info structure.
3597 Added optional CCL (ISO8777) interpreter as separate module. Available
3600 --- 1.2 1996/6/10 (1st anniversary release)
3602 Added Summary record syntax. Lightly tested.
3604 Added OPAC record syntax. Untested.
3606 Added ResourceReport service encoders/decoders. Untested.
3608 Fixed bug in z_Unit - wrong tagging on unitSystem.
3610 Fixed bug in the DiagRecs decoder.
3612 Added options for max PDU size and session timeout to frontend-server.
3614 Added documentation of query-language parsers and other supporting utilities.
3616 [frontend-server] Added Attribute set to the bend_scanrequest API.
3618 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3619 surrogate diagnostics were generated.
3621 [retrieval] Allow multiple local values for attribute.
3623 [retrieval] Allow multiple attributes per element in .abs files. index type.
3625 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3627 --- 1.1pl2 1996/4/10
3629 Minor changes, mostly specific to Zebra's requirements (retrieval)
3633 Repaired bug in frontend server when running multiple listening
3634 endpoints in dynamic mode.
3636 z_External() now won't break if a known, ASN.1 value comes encapsulated
3637 in an octet-string. The value will pass through unmodified in an Odr_oct.
3639 Added a bit of code to the demo client to decode & display
3640 ASN.1-structured records represented in the octet-aligned branch of
3641 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3643 Added z_ext_getentbyref() to the ASN module. Doc updated.
3645 * Completed the SCAN definition in the ASN module. This may break SCAN
3646 code based on older YAZ-versions at compile-time. The fix is easy -
3649 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3650 under the SCAN definition. Remember to initialize this, server-people.
3652 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3653 that this does not extend to ODR and ASN.
3655 Comstack allows insertion of established socket (primarily for
3656 inetd-operation of servers). Doc updated.
3658 Front-end server can now start from the inetd in TCP mode. Doc
3661 --- 1.0pl4 1996/1/24
3665 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3666 the rank and record number.
3668 Adjustments to the frontend server.
3670 Fixed diagnostic BER dumper. It ignored the file argument.
3674 Various changes to retrieval module.
3676 Changed the union discriminators of the protocol files from enums to
3677 ints paired with #defines.
3679 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3682 *Changed operator in the RPN structure to 'roperator', again to avoid a
3685 Fixed problems in Explain decoders/encoders.
3687 --- 1.0pl2 1995/12/6
3689 Memory bug in log module fixed.
3691 --- 1.0pl1 1995/12/5
3693 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3695 Bug in Explain DatabaseInfo module fixed.
3697 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3701 The shift to v1.0 signals that we now consider the *core* functionality
3702 of YAZ reasonably stable (the core being more or less equivalent to
3703 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3704 tested (Explain not at all - though that will happen soonish).
3706 Minor changes to code to support Windows port.
3708 Various minor changes after we're getting to use GRS-1 & co. more.
3710 Added Espec-1 format.
3712 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3713 of the protocol and it cannot be selected when encoding (maps into 'string'
3714 when decoding). Needed to talk to some servers.
3716 Demo client can request simple element set names.
3718 Added Diagnostic Format encoders/decoders.
3720 Added simple Close handling to frontend server (no hooks for resource
3721 reporting yet), and demonstration client.
3723 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3725 --- 1.0b3 1995/08/24
3727 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3728 handled incorrectly when records were requested in the searchResponse. This
3729 will only affect you if you use the frontend-server.
3731 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3732 Test-client will ask for and print GRS1. Ztest will return dummy records
3735 Added Explain encoders/decoders to the service-level API. Untested.
3737 Added Extended Services: Item Order encoders and decoders to the Service-
3738 level API. Untested. We could use a recent copy of the pertinent bits
3739 of the ILL protocol to add those bits.
3741 Added diagnostic format 1 encoders/decoders to the service-level API.
3744 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3745 odr_cons.c, which causes a more correct output.
3747 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3748 was always set to 0 when no records were requested in the searchRequest.
3750 * Added better external-handling. This shouldn't harm old code that
3751 *encodes* externals. It can break code that looks for a
3752 'single-ASN1-type' representation, since those types that are known
3753 are now decoded immediately. Look at the SUTRS sample code in
3754 seshigh.c and client.c. Documentation updated.
3756 Handling of structured records in bend_fetchresponse. Length -1 marks
3757 structured record, type is deduced from format field.
3759 --- 1.0b2 1995/06/27
3760 Fairly quick maintenance release to add SUTRS support.
3762 Fixed handling of SUTRS records in the demonstration client.
3764 * Added format field to the bend_fetchrequest and bend_fetchresponce
3765 structures of the backend API (frontend server). When the record is
3766 returned, the value of the format field is mapped to an OID. The
3767 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3768 of the record. The special value VAL_NONE in the bend_request means
3769 that no specific format was requested by the client. Documentation
3770 updated accordingly. Test server (ztest) will return a fixed dummy
3771 SUTRS record if your client requests SUTRS.
3773 Documentation updated accordingly.
3775 You can now set external libraries and RANLIB support in the top-level
3779 First public release.
