3 Allow yaz-ztest to return user-defined records (one record per file).
4 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
6 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
7 Use the stream write instead of odr_printf which has a 4K tmp buffer.
9 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
13 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
14 can read and write this format. For record format JSON, yaz-ztest returns
17 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
18 converted to @å , 0xa732 is converted to @Å instead of @a733, @a732 .
22 Improve error reporting for ICU chains YAZ-707
23 Report config element+rule when ICU status is "failure".
25 ZOOM: stop fetching if present response has no records YAZ-710
26 Some targets return less records than their hit count would suggest.
27 This prevents ZOOM from continuing to fetch records if any present
28 response has 0 records in the response.
30 Ensure that GFS calls exit if any listener fails YAZ-710
31 Before, if XML config was in use, it would start the default
36 yaz-ztest: -V shows version (like yaz-client -V)
38 New iconv encoding: danmarc YAZ-692
40 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
42 daemon: only wait for immediate child rather than all children. YAZ-704
44 yaz-client: fix setting of SRU record schema. If scheme was unset, it
45 could lead to invalid memory reference.
49 yaz-ztest returns schema for MARCXML test records. SRU require that
50 recordSchema for records.
52 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
53 instead of non-surrogate diagnostic. This is a per-record failure.
55 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
56 may refer to multiple listeners now. Attribute listenref is a comma separated
59 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
60 option is given for GFS, the dirname of filename (for -f) is used
61 as prefix for options such as cql2rpn, ccl2rpn, etc.
63 Content-Type charset fixes YAZ-701 . Do not inspect charset in
64 Content-Type header for SOAP when decoding SRU. The payload (XML)
65 itself tells what encoding it is. In response, never supply encoding
66 in Content-Type. The response payload (XML) tells what it is (with no
67 encoding in XML it's UTF-8).
69 HTTP decoding: allow blanks in URL paths YAZ-700
73 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
74 and facets. Ensure recordData and recordSchema are always present in
75 record element, because they are required.
77 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
80 Simplify in a lot of places using odr_strdupn.
82 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
86 Increase various buffers in GFS's statserv_options_block
87 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
88 This change makes many type-casts redundant, and, thus simplifies code.
90 Remove last bits of WAIS support.
92 Remove member 'size' from Odr_oct.
94 Slim down the public part of 'struct odr'. Most elements are not part
95 of struct Odr_private.
97 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
98 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
99 In particular facets are supported in both client - and server side.
100 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
101 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
102 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
103 both request/response). This is what a search handler in the GFS
104 will see (regardless of whether operating in SRU mode or Z39.50).
106 Changes to the srw.h (SRU/Solr) definitions include:
107 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
108 (char*), which replace union query and query_type (int). This is because
109 SRU 2.0 supports a queryType parameter. This also means that, to carry
110 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
111 x-pquery=PQFstring (extention parameter). The extension parameter
113 - New element, packing, that has information about SRU
114 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
116 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
118 New element, packing, in Z_SRW_explainRequest.
120 New elements in Z_SRW_scanRequest, queryType and scanClause.
121 These replace query_type and scanClase untion. This is similar to what
124 --- 4.2.69 2013/10/01
126 GFS: log when closing down - at least SIGTERM YAZ-684
127 Also change formatting WRT PID logging a bit.
129 Improve display of MARC records with multi-byte subfield IDs YAZ-695
130 In some rare cases subfield identifiers are multi-byte characters.
131 This will try to deterime length of those and split accordingly.
132 This affects display in line mode as MARCXML/MarcXchange. The encoding
133 of ISO2709 is the same.
135 Change inp argument to const for yaz_read_UTF8_char.
137 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
139 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
141 Better check of marc leader info YAZ-691
142 Problem is that some systems generate MARCXML/MarcXchange with
143 funny headers. These will not work if encoded as ISO2709.
144 Some tests produce new output, due to updated warning messages
146 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
148 yaz-client: display MAB records YAZ-689.
149 Thanks for Heiko Jansen for this patch.
151 New utility z_get_HTTP_Response_server which allows both HTTP server name
152 and HTTP server URL to be given in response.
154 Debian: do not depend on obs tcl8.3.
156 Debian: do not depend on obs libicu36-dev.
158 --- 4.2.68 2013/09/23
160 GFS: pass additionalSearchInfo to search memeber search_input if
161 given. Otherwise pass otherInfo. Request for facets and other search
162 related things will be passed there in future versions of YAZ.
164 New ZOOM setting, authenticationMode, which allows authentication
165 paramters to be encoded in the URL rather than via HTTP Basic auth.
168 rpn2solr: fix nested AND/OR handling. YAZ-685
170 Add comparison routines for some Z-types, such as NamePlusRecord,
171 RPNQuery, Query, RecordComposition and OtherInformation.
173 --- 4.2.67 2013/09/19
175 Don't decode MAB as MARC. Just like we don't attempt to decode
176 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
178 CCL: allow quoted terms for date ranges. YAZ-681
180 Introduce ccl_parser_qual_search. This function makes old function
181 ccl_qual_search, from YAZ 2, available again.
183 Add yaz_facet_list_to_wrbuf. YAZ-683
185 --- 4.2.66 2013/09/11
187 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
188 schema was given for search. YAZ-675
190 Add Solr date range searches. YAZ-621
192 --- 4.2.65 2013/08/22
194 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
196 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
198 ISO2709/MARC parse most octet aligned records; not just those that
199 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
200 MARC parse more records instead of just dumping as is. YAZ-670
202 ZOOM: proper caching for variations of record schema. YAZ-671
204 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
206 --- 4.2.63 2013/07/17
210 --- 4.2.62 2013/07/11
212 New utility z_get_HTTP_Response_details - an extended version of
215 New utility yaz_url_get_error which returns error message of last
216 failed yaz_url_exec call.
218 yaz-url and url functions: allow max HTTP redirects to be controlled.
220 New functions yaz_file_glob2, yaz_xml_include_glob.
221 These functions takes a flags parameter, which, for now only controls
222 whether to fail inclusion of a non-existing file (without glob
223 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
225 --- 4.2.61 2013/06/20
227 For MARC XML parsing, allow record without leader. A fake/default leader
228 is inserted and a warning is tagged with the record.
230 ICU: fix leak in in icu_iter_get_org_info.
232 --- 4.2.60 2013/06/14
234 ICU: fix bug in icu_iter_get_org_info (un-init variable).
236 --- 4.2.59 2013/06/11
238 Implement z_HTTP_header_remove.
240 --- 4.2.58 2013/06/11
242 ICU: Disallow 0 ptrs for some ICU string utilities.
244 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
245 returns original tokens (before normalization).
247 CCL: avoid z39.58/regex truncation when not needed. Apply only the
248 conversion of those masks, when absolutely necessary.
250 CCL: configurable masking character - @mask. Default masking character
253 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
254 full response anyway, so a Transfer-Encoding header will obstruct the
257 --- 4.2.57 2013/05/15
259 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
260 picking a socket. Problem is that some systems has IPV6 support, but
261 we can't create sockets for them, so we pick AF_UNSPEC first.
263 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
264 use content_len to determine resulting Content-Length in HTTP response
265 and NOT Content-Length supplied in headers by user.
267 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
268 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
270 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
273 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
274 with big endian and unsigned char (by default).
276 --- 4.2.56 2013/04/26
278 Fix yaz-client connect (crash in 4.2.55).
280 --- 4.2.55 2013/04/26
282 Fix proxy/host problem for ZOOM that could occur if unix sockets
285 New Debian package libyaz4-dbg.
287 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
288 differently in tcpip_close.
290 --- 4.2.54 2013/04/17
292 Windows installer of YAZ includes YAZ4J as a component.
294 CQL: allow "extra terms" again, by default. Thus, the CQL parser
295 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
296 and earlier. CQL parser may operate in strict mode where queries
297 not conforming to the standard BNF are rejected (syntax error).
298 Whether the CQL parser operates in strict mode is controlled with
299 cql_parser_strict . Strict mode enabled with option -S for utilities
300 cql2pqf and cql2xcql .
302 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
304 --- 4.2.53 2013/04/10
306 New charset, MARC-8c, which is like MARC-8 but allows control characters
307 0x01 through 0x1F, except ESC to be passed through verbatim.
309 Fix a problem with duplicate sub field character in MARC output. Problem
310 happened only when output was MARC-8 encoded.
312 --- 4.2.52 2013/04/03
314 yaz-ztest: Use hash for fake hit count. Before, random number was used.
315 This is problematic for unit tests using yaz-ztest. This patch also makes
316 a hash for CQL queries. For RPN, any term with a leading digit will be
317 treated as pseudu hit count (to force any particular hit count by a client).
319 yaz-ztest: return unique MARC dummy records. Beyond record offset
320 24, the author surname is patched with offset to make all records
323 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
324 on system wide default (/proc/sys/net/ipv6/bindv6only).
325 @4 binds to IPV4 only. @6 binds to IPV6 only.
327 Update CQL API documentation a bit
329 CQL: don't accept extra terms for queries. Makes the CQL parser
330 stricly conformant to the standard.
332 --- 4.2.51 2013/02/12
334 GFS: scan handler gets extra_args from request and may return extra
335 response data . That's for SRU only.
337 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
339 --- 4.2.50 2013/01/30
341 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
343 OPACXML: sync spelling of availabilityDate in XML to that of Schema
344 opaxxml.xsd. The schema had the correct spelling of this member always.
345 The ASN.1 was mis-spelled and still is (API change) - we are
346 not changing this. However, the OPAC to XML conversion had yet
349 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
352 New function, z_ext_record_oid_nmem, which is similar to
353 z_ext_record_oid but takes NMEM rather than ODR
355 --- 4.2.49 2013/01/18
357 ICU: New conversion element 'join' which joins tokens into one
358 with a custom character given by rule attribute.
360 --- 4.2.48 2013/01/10
362 New GFS search member: present_number. This is a hint to the
363 search handler how many records are going to be fetched immediately
364 following search. There's no guarantee that it's going to be the case,
365 since it depends on hit count (for Z39.50 piggyback) and whether errors
368 Make a few functions static (private). The functions getbyte_stream,
369 ungetbyte_stream and yaz_gets are now private. They were never declared
372 yaz-marcdump: exit(5) for serious decoding errors
374 ISO2709 decoding: be more picky WRT header
376 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
377 was only used as to indicate that next-result-set-position should be
379 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
380 Based on patch from Ashley Sanders.
382 Make some functions static/private in PQF parsing. Those functions were
383 never declared in a public header and so should not be in use by
384 applications based on YAZ.
386 --- 4.2.47 2012/11/23
388 ZOOM: special options to control APDU logging.
389 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
390 logging of APDUs until "saveAPDU" option is set again. If logging is
391 already enabled the effect is that current APDU buffer is cleared.
392 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
393 logging (default behavior on new connection).
394 The APDUs sent/received can be obtained by using
395 Using ZOOM_connection_option_get(c, "APDU") or
396 ZOOM_connection_option_getl(c, "APDU", &l).
398 GFS: relay implementation_version from backend
399 From 3.0.40 and later, implementation_version from backend was
400 not used in init response at all.
402 --- 4.2.46 2012/11/15
404 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
405 mode at all. Probably never did.
407 Make a new version of ztest.pem that, at least, is not expired.
409 --- 4.2.45 2012/11/13
411 Fix description of CCL directive 'case'.
413 More tight checking of form arguments (yaz_uri_to_array). Makes
414 YAZ better at rejecting big and/or bad POSTs.
416 SRU decoding does not report more than up to 10 invalid arguments.
418 rpn2cql: less quotes in generated terms. Semantics unchanged, but
419 it's prettier this way.
421 --- 4.2.44 2012/10/25
423 New utility yaz_decode_init_diag. Defined in proto.h.
425 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
426 given for unix local socket.
427 The COMSTACK string for doing so is:
430 unix:/myfile:tcp:localhost:9999/mybase
431 unix:/myfile:localhost:9999/mybase
432 unix:/myfile:http://fakehost/mybase
434 debian: Use dpkg-buildflags in build process.
436 --- 4.2.43 2012/10/19
438 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
439 global's SRU service uses a recordPosition scheme starting from zero.
440 First record's position should be one
441 according to the standard.
443 --- 4.2.42 2012/10/18
445 Allow more namespaces for SRU. This is to allow, for example, an
446 incorrect namespace returned from server
447 http://services.igi-global.com/sru .
449 Minor fixes for compilation on Windows.
451 --- 4.2.41 2012/10/11
453 daemon: log total number of bad signals from child on stop so that it
454 is more easy to spot problems with child worker processes.
456 retrieval: empty backend name attribute omits element set
457 from being used in retrieval.
459 --- 4.2.40 2012/10/04
461 Implement Solr sort strategy "solr", similar to sru11 sorting.
462 This will implement the correct parameters on Solr requst to do
465 --- 4.2.39 2012/09/28
467 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
470 MARC: Extra/missing indicator handled for MARCXML.
471 The indicator length is given in header and is the same for the
472 whole record. If attributes ind1, ind2 are missing, then content
473 character defaults to blank. Extra indicator attributes (beyond)
474 indicator length are treated as an error.
476 Reformat: delete trailing whitespace
478 --- 4.2.38 2012/09/17
480 MARC: fix non-ASCII characters for leader. This is to ensure we can
481 generate XML in UTF-8.
483 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
484 in one node with structure word.
486 --- 4.2.37 2012/09/04
488 yaz-json-parse: JSON output may be pretty printed by using option
491 Increase default value of max message for Z39.50 Init for GFS, ZOOM
492 and yaz-client. Old value was 1 MB. New value is 64 MB.
494 --- 4.2.36 2012/08/22
496 yaz-client: don't display bogus records from SRU servers. Some SRU servers
497 return more records than given by *maximumRecords*. Skipping those in
500 record_render: simplify buffer return handling and fix at least one bad
501 memory reference, that broke the test_embed_record sometimes.
503 Allow http://user:pass@host notation for yaz_url_exec.
505 zoomsh: allow shell command to be executed. Via the system(3) call.
507 yaz_poll: Allow num_fds == 0
509 yaz-client: fix bad encoding of "itemorder item". The itemorder
510 item <no> - command forgot to use length of encoded Item Request
511 package. Error present since YAZ 3.
513 yaz-ztest: fix bad usage of session handle. Bug was introduced when
514 result sets were saved (271a9c83).
516 SRU recordPacking: guess record packing in response rather than looking
517 at the recordPacking element which, OF COURSE, changed semantics in SRU
520 Decode SRU 2.0 responses. The official namespace for responses, according
521 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
522 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
523 nature.com's server, however, usee namespace
524 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
525 we are now using a glob-expr to match up the namespace. ZOOM C and
526 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
527 I can not find a single real example showing the "real" namespace in
528 the documentation from OASIS. The namespace for requests is different
529 from responses, but this is not added to YAZ yet, when we don't encode
532 --- 4.2.35 2012/06/26
534 zoom/record_render: add support for Base64 decoding fo MARC records
535 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
536 which will decode base64 + ISO2709 marc-8 encoded material from text node
539 --- 4.2.34 2012/06/07
541 Add missing definitions ZOOM_resultset_get_facet_field_by_index
542 and ZOOM_resultset_facets_names.
544 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
547 Change APDU dump printing to avoid long leading blanks. For levels 16
548 or larger the level is shown and the indentation is truncated but
549 recursed with modula 8. This makes it still reasonable easy to read
550 - even for nested BER dumps.
552 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
553 return 0 (incomplete package) in case where the BER package was
554 considered too nested (return value of -2).
556 dumpber: lines of level 15 are not indented further. Two spaces per
557 indentation; indentation 15 or more is indented to a fixed indentation
558 and augmented with a level=<no> indication.
560 zoomsh: increase max size of command+args
562 GFS: No limit in RPN buf size in CQL to RPN conversion.
564 --- 4.2.33 2012/05/09
566 New function for daemon utility, yaz_daemon_stop .
568 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
570 --- 4.2.32 2012/04/25
572 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
573 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
575 --- 4.2.31 2012/04/23
577 YAZ daemon utility relays SIGUSR1 to child process.
579 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
580 would result in en empty database list - which in turn would result in
581 encoding failure for search.
583 Fix reading beyond string in yaz_sort_spec.
585 --- 4.2.30 2012/04/11
587 Add two new SRU diagnostics:
588 236: Access to specified database denied
589 1015: Init/AC: Maximum number of simultaneous sessions for Userid
591 Document the very useful ZOOM-C option "apdulog".
593 CQL to RPN: term may be passed through verbatim. This is enabled with
594 truncation.cql . The assumption being that the term is already CQL.
596 --- 4.2.29 2012/03/20
598 record_conv: leader spec may be given for marc element.
599 The leader spec is given as attribute leaderspec for element marc.
600 For example to convert a MARC21 record from MARC-8 to UTF-8:
601 <marc inputformat="marc" outputformat="marc"
602 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
604 record_conv: allow user-XSLT params. For example:
605 <xslt stylesheet="MARC21slim2DC.xsl">
606 <param name="myparameter" value="myvalue"/>
607 <param name="otherparameter" value="othervalue"/>
610 record_conv: fix error handling for missing marc charsets.
612 CQL: fix extra terms in wrong order.
614 --- 4.2.28 2012/03/06
616 record_conv: modify new API for conversion types. The conversion types
617 may be passed in new functions yaz_record_conv_configure_t and
618 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
620 Avoid mixed statement/variable declare; fixes compilation with Visual
623 --- 4.2.27 2012/02/28
625 Add non-standard SRU diagnostic: 235: "Database does not exist".
626 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
627 Update SRU to Bib-1 diagnostic maps accordingly.
629 CCL: add two new diagnostics for unsupported masking. The new
630 diagnostics are: "Embedded truncation not supported" and
631 "Single charcacter mask not supported".
633 --- 4.2.26 2012/02/23
635 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
637 --- 4.2.25 2012/01/11
639 Build YAZ for Ubuntu Oneiric.
641 CCL: allow parantheses for proximity operands. For example CCL query
642 (a) % (b) is now allowed.
644 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
645 marked dead, rather then being destroyed. If not, the session memory is
646 being free'd before the search/scan handler is finished. Also destroy
647 'request' memory in request_release rather than in various places,
648 which resulted in leaks from time to time.
650 --- 4.2.24 2011/12/21
652 cql_sortby_to_sortkeys: honor sort prefix.
654 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
655 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
656 The rpn2cql family of functions now always returns quoted CQL terms.
658 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
660 --- 4.2.23 2011/12/15
662 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
663 sequence is treated as one. For example, &&a=b&&&c& is identical to
666 --- 4.2.22 2011/12/05
668 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
669 APDUs for a connection to a WRBUF.
671 --- 4.2.21 2011/11/23
673 Fix cql_sortby_to_sortkeys. Completely broken before.
675 Make CCL's @truncation work again.
677 --- 4.2.20 2011/11/09
679 New ZOOM connection setting: tproxy. It's like proxy, but does not
680 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
681 to set resolved address + port for a connection outside ZOOM itself.
683 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
685 --- 4.2.19 2011/11/07
687 Fix uninitialized variable in Solr spell support (could cause SEGV
688 for SRU response decoding).
690 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
691 back-end's addinfo through into the ZOOM response addinfo.
693 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
694 they are separated by a colon and a space rather than simply
697 --- 4.2.18 2011/10/28
699 Add support for Solr spell-checking/suggestions through ZOOM.
700 If a Solr target has been configured correctly for spelling-checking
701 and suggestions, these will now be returned on the ResultSet option
702 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
704 --- 4.2.17 2011/09/28
706 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
707 with a flag whether to substitute escape sequences or not.
709 --- 4.2.16 2011/09/22
711 Fix nmem_strsplit_escape to substitute escape char properly.
713 New option for zoomsh -e , which makes it abort on first error and
714 return process exit code to indicate success/failure.
716 YAZ options utility supports special option -- which makes all it treat
717 all following arguments as non-options.
719 --- 4.2.15 2011/09/16
721 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
722 searched if absolute filename is given.
724 Fix conv_xslt() error-reporting when stylesheet is not found.
725 (The value of fullpath is meaningless in this situation.)
727 --- 4.2.14 2011/09/07
729 Fix problem in CQL sort node creation: un-initialized memory.
731 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
732 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
733 CQL sortby depending on whether Type-1 or CQL is actually sent to the
736 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
737 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
739 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
740 will make it possible to use both single-character mask (#) and wildcard (?)
741 in CCL . Throw diagnostic for left truncation because that is not supported
744 --- 4.2.13 2011/09/01
746 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
747 cases using escapes (\-sequences) and masking.
749 PQF parse fix: A trailing backslash followed by end-of-string (\0)
750 would result in a read one byte beyond string.
752 rpn2ccl may use Z39.50 masking for terms (t=z).
754 ICU check fix. Don't include library -lCrun on Solaris, unless present.
756 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
757 not --cppflags (which seeems like an error in icu-config).
759 --- 4.2.12 2011/08/27 RPM package only
761 cql2ccl: fix conversion of terms: operator characters were not
764 --- 4.2.11 2011/08/25 RPM package only
766 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
767 CCL parser will map both # and ? to their regular expression
768 quivalents (. and .*).
770 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
771 of reserved CQL characters.
773 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
774 is, so that they are passed through.
776 --- 4.2.10 2011/08/24
778 ZOOM SRU mode: more aggressive re-connect.
780 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
781 made available as a utility function, declared in <yaz/logrpn.h>
783 rpn2cql_structure() supports proximity nodes (except that the Type-1
784 proximity node's "exclusion" binary is ignored, as there is no way to
785 express that in CQL). Fixes bug #4564.
789 Fix SEGV that could occur if set command of zoomsh was given without
790 value (2nd argument).
792 Fix SEGV that could occur if unsupported transport was given for
793 COMSTACK - say https (when SSL was unavailable).
795 Build yaz-url on Windows too.
799 New utility to get web content. Header is url.h. A command line tool
800 yaz-url is part of the distribution and packages.
802 Fixes for SSL COMSTACK (when gnutls is in use).
804 New functions yaz_base64{encode,decode}. Header is base64.h.
808 ZOOM C includes HTTP response buffer as additional info if it fails
809 to decode the SRU response.
811 Make wrbuf_json_puts available.
815 zoom: throw diagnostic for invalid value for option "sru". Before a
816 bad SRU request was sent.
818 Adding new utility wrbuf_vp_puts.
820 Add cclxmlconfig.obj to win/makefile. It was missing completely.
824 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
825 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
826 redirect was used at the same time.
828 MARC line mode decoding: be less picky about length given - first
829 5 digits of header that is.
831 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
833 Changes to decoding of SRU records: a record with recordPacking=xml is
834 modified with a new root element <yaz_record> if the recordData contains
835 multiple children elements. This is to make the record XML parseable
838 RPN to Solr conversion: encode special characters.
840 Generic Frontend Server: fix uinitialized member, stepSize.
844 Fix a bug in SRU decoding of records.. The database records stored
845 had un-initialized memory, but it would only be seen with yaz_record_render
846 and type_spec="ext" .
848 Fix a bug in ccl_qual_dup introduced in 4.2.3.
852 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
856 Add new utilities to convert from CQL to CCL . These utilities have
857 prefix cql_to_ccl defined in cql.h.
859 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
860 lead to memory heap corruptions when ICU utilities were in use.
864 Make compilation work without Libxml2.
866 yaz-client: remove redundant blanks in display of searchResult-1 term
871 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
872 resulting CQL node (tree) in a new node CQL_NODE_SORT.
874 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
875 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
876 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
877 Note that the CQL sortby spec is only converted when the GFS is already
878 converting from CQL to RPN (cql2rpn element).
880 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
881 specify whether to collapse delimitors or not. The existing nmem_strsplit
882 do collapse (collapse parameter = 1).
884 Windows installer: For NSIS, set InstallDir depending on x86/x64.
886 Rename internal func yaz_use_attribute_create. While non-static, this
887 function is not declared in a public header.
891 Add -lCrun when linking with ICU on Solaris.
893 More quicks character set conversions for OPAC records.
897 fix problem with record_render: records were converted (character set
898 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
902 SRU: add methods for handling DADS SRU-proxy facets.
904 Separate OPAC record character set for ZOOM_record. yaz_record_render
905 allows a character set given as charset=from/opacfrom,to where 'from' is
906 the character set of a bibliographic record, 'opacfrom' is character set
907 of OPAC record and 'to' is the target character set.
911 yaz-client: show may XML format records. Command show followed by 'format'
912 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
915 src/stemmer.c: Avoid using unnamed union. It is not supported by some
918 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
921 Update yaz.spec to operate on both SLES11 / Centos 5.5.
923 RPM: Release includes 'indexdata' name. Use indexdata in release name so
924 this package can be distinguished from other vendors.
926 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
927 as determined by configure
929 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
931 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
932 returns no error and no record, the present request is considered
933 partial (only a subset of the records could be returned by backend), and
934 so it is appropriate to set Present Status to partial-4.
938 Move yaz-config man pages to section 1.
940 More documentation about Solr.
942 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
943 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
944 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
945 peers on some Linux systems. However, in general that does not work
946 so YAZ can not rely on that to work. Debian changed behavior in this
947 respect from Debian lenny to Debian squeeze (still testing as of Oct
949 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
951 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
955 Fix yaz-config output: echo_source not set correctly by configure.
959 Solr Web Service support for yaz-client and ZOOM.
961 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
963 --- 4.0.12 2010/08/17
965 Z39.50 facet support. Facet specifications are passed for search in
966 other-information with ASN.1 as defined in facet.asn and OID
967 .10.1000.81.5 . Facets are expressed as an Attribute list as known
968 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
969 3 is limit (number of entries to get in response). yaz-ztest returns
970 dummy facets if a client asks for them.
972 --- 4.0.11 2010/07/09
974 CCL fixes: bug 2895 and bug 3539.
976 GR1-display: add comma in display - was removed by mistake in
979 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
981 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
983 --- 4.0.10 2010/06/18
985 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
986 result set from a connection. The result set will be on its own
987 thereafter; no operations on it will perform retrievals from a target.
988 Only cached copies are returned.
990 ZOOM C:fix case for HTTP servers responding with Connection:close.
991 Ensure that if there is a current task it is resumed (like fetching
992 more records in a result set) . Bug #3484.
994 PQF parser: use odr_atoi for Odr_int (not atoi)
996 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
997 values that contain any non-digits are treated as string attributes
998 (previously decoding only checked for leading character ([0-9]). PQF
999 encoding: attribute string values are not surrounded by double-quotes.
1001 --- 4.0.9 2010/05/21
1003 New utility for managing threads - thread_create.h.
1005 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1006 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1007 but YAZ' implementation do.
1009 Fixes for yaz_cond-functions on Windows 7.
1011 DLL export more symbols.
1013 zoomsh: show record do NOT render opac.
1015 Remove *.la files from Debian and RPM packages.
1017 --- 4.0.8 2010/05/11
1019 Debian package libyaz-dev depends on libgnutls-dev again (was
1020 removed in YAZ 4.0.6, but due to Libtool it is still needed
1021 even though yaz-config do not list libgnutls libs).
1023 ZOOM: Use only one WRBUF for returning string results for
1024 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1026 ZOOM: ZOOM_connection do not use a shared pointer to
1027 ZOOM_resultset after ZOOM_resultset is destructed by
1028 user. Reverts to YAZ 4.0.4 behavior.
1030 --- 4.0.7 2010/05/04
1032 record-conv: fix problem with at least one XSL conversion -
1033 due to probably incorrect usage of XML XSL documents.
1035 --- 4.0.6 2010/04/29
1037 Fix yaz-config for static mode and the use of SSL (gnutls).
1039 --- 4.0.5 2010/04/29
1041 Forward decl timeval struct in mutex.h and gettimeofday.h.
1043 yaz-config: fix 'static' mode linking.
1045 --- 4.0.4 2010/04/28
1047 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1048 are wrappers for pthreads or Windows. For Windows these are put in
1049 a separate DLL: yaz_cond4.
1051 libyaz.la (whole source) is compiled with thread. If thread support
1052 is enabled enabled, all source of YAZ is compiled with treading support.
1053 This allows core utilities such as yaz_log to use thread facilities.
1054 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1055 thread utilities. This commit moves mutex utilities (mutex.c) from
1056 libyaz_server.la to libyaz.la.
1058 yaz-json-parse displays leading text until error.
1060 --- 4.0.3 2010/04/09
1062 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1063 patch from Giannis Kosmas.
1065 SRU: no longer URL encode SRU database. The URL for an SRU server is
1066 a URL and such is alreeady encoded - at least when given with leading
1067 http:// or https://. This reverts behavior to YAZ 3.0.50.
1069 Support for new MARC XML notation TurboMARC which like MARCXML is a
1070 complete representation of MARC/ISO2709.. This one, however, is more
1071 compact and allows for faster processing with XSLT. TurboMARC can be
1072 used in the marcdisp.h API, from the yaz-marcdump utility and from
1075 yaz-ztest can be configured - via the database - to perform certain
1076 delays when it performs operations search, present and single record
1077 fetch. This allows testers to make yaz-ztest act as a real or even slow
1078 Z39.50 server. Refer to the yaz-ztest man pages for details.
1080 --- 4.0.2 2010/03/09
1082 wrbuf_destroy allows NULL WRBUF passed to it.
1084 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1086 Add ZOOM_connection_close.
1088 No fixed size buffers for ZOOM shell - bug #3257.
1090 tstodr: make it work on s390 platform.
1092 New icu iterator-functions. The new icu_iter-functions makes it possible
1093 to use ICU chains from many threads.
1095 yaz-client: better syntax check for show command.
1097 --- 4.0.1 2010/01/26
1099 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1102 New simple local-file XML include facility which allows file glob-patterns.
1103 Refer to yaz/xml_include.h.
1105 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1108 ZOOM_record_get supports new parameter "format" which makes it format XML
1111 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1112 JSONText in ECMA-262) is JSONValue, not JSONObject.
1114 --- 4.0.0 2010/01/20
1116 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1117 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1119 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1120 POSIX/Unix builds .so with major version 4.
1122 Remove old LOG_-defines from log.h. They have been obsolete and
1123 undefined by default for the last 5 years.
1125 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1127 GFS: Remove socket (int *fd) from search_rr handler. The socket
1128 descriptor ptr is a facility that allowed a search handler to supply
1129 a socket which would serve as a callback - when search was complete.
1130 This facility has now been in use for years.
1132 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1133 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1134 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1135 returns 'const char *' rather than 'char *. The returned string is
1136 read-only and should not be modified by applications. COMSTACK cs_close is
1137 now a void function - it no longer returns int. No applications check for
1138 the value and the implementations has always returned 0.
1140 ZOOM: use size_t for scan hit counts and str size. Functions
1141 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1142 occ (hit count) and len (string length) are now of type size_t pointer
1143 rather than int pointer. This is to be able to represent large hit counts
1144 and to also just to use the proper type for string length (strlen result).
1146 New JSON parser. Refer to include/yaz/json.h .
1148 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1149 Used to be int in some cases. Many wrbuf_-functions used to return an int
1150 indicating some length.. These return values were never used. And so they
1153 ODR: odr_malloc, odr_total now takes size_t for size.
1155 clone_z_type: fix leak; occurred for encoding failures.
1157 --- 3.0.52 2009/12/03
1159 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1160 bug was introduced in 3.0.51.
1162 --- 3.0.51 2009/12/02
1164 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1166 tcpip comstack: fix leak for getaddrinfo.
1168 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1169 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1170 Decoding of SRU "path" database is performed by private function
1171 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1172 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1174 yaz-client: honor base command for SRU. Change when database setting
1175 is applied for SRU and ensure it is kept when a connection is reset.
1176 Change also the way errors are displayed or SRU (decoding of packages).
1178 --- 3.0.50 2009/11/02
1180 Add support for extra request / response data for SRU codecs and GFS.
1181 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1182 for extra data response buffer and length. For the GFS, both request
1183 and response data (XML) is carried in extra_args and extra_response_data
1184 for the search handler. Patch by Ko van der Sloot.
1186 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1187 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1188 10010). This fixes bug #2113.
1190 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1191 cmdfile included a 'quit' command that would result in a memory violation.
1193 --- 3.0.49 2009/10/01
1195 Make a number of functions defined in xmlquery.c static. These have
1196 never been declared in a public header file (yaz/xmlquery.h) and was
1197 made public by mistake.
1199 Improve speed of character conversions (iconv utilities). This makes
1200 conversions from MARC-8 faster.
1202 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1203 unless type desired is "raw". This will prevent type "xml" from
1204 returning ISO2709 .. Which obviously can not be XML parsed.
1206 Fix memory leak in ZOOM that would occur if option apdulog was used
1207 on a re-used connection.
1209 Frontend server logs HTTP requests.
1211 Frontend server now sends Z39.50 close when it times out (sesssion has
1212 been idle for too long). Versions 2.0.30 and earlier also sent close.
1213 But due to a mistake this was disabled in all versions after that, i.e.
1214 the server would just close the socket immediately.
1216 yaz-client emits a better message when receiving an unrecognised
1217 userInformationField.
1219 Skip zero-length subfields when decoding ISO2709. This rare case happens
1220 if a record has two FS characters in a sequence. Without this patch
1221 there would be a reference beyond char array in using_code_len fragments
1224 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1226 --- 3.0.48 2009/08/28
1228 The show command offered by the zoomsh command now takes a 3d optional
1229 parameter type which is what is passed to ZOOM_record. If the type
1230 argument is omitted, "render" is used.
1232 RPN to CQL conv may use USE string attributes (bug #2978).
1234 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1236 --- 3.0.47 2009/07/08
1238 Function yaz_xml2query allows a diagnostic element in the PQF XML
1239 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1240 code and additional info respectively.
1242 The BER BOOLEAN is now the integral type Odr_bool which still happens
1243 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1244 typedef'd to Odr_int. This is still an integral 'int', but it may be
1245 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1246 ASN-1 compiler as well as programs has been updated to use the new types.
1248 --- 3.0.46 2009/06/08
1250 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1251 only the bibliographic record was rendered. For type=opac, an OPAC
1252 record is only returned if it is present.
1254 iconv: small fix for encoding of advancegreek.
1256 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1258 yaz-client: option auto_reconnect=on really reconnects.
1260 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1262 server: avoid null ptr ref for for yaz_poll errors.
1264 build: fix RPM build for RHEL 5.3.
1266 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1268 --- 3.0.45 2009/03/31
1270 Fixed bug #2709: TCP connect returns Invalid argument.
1272 Fixed compilation for mingw.
1274 Honor charset for raw records (ZOOM_record_get).
1276 Fixed use of errno for threaded mode that was seen on Solaris 10.
1278 Fixed argument passing with blanks in value for Windows Service.
1280 Disable YAZ' own log rotate by default (no 1 GB limit).
1281 The variable l_max_size which specifies the log file limit is set to 0
1282 (DISABLED): This is due to the fact that YAZ is most often deployed using
1283 logrotate. Also YAZ can not perform log rotate because of unsufficient
1284 permissions (setuid).
1286 --- 3.0.44 2009/02/17
1288 List supported encodings in man page for yaz-iconv.
1290 Fixed missing SSL libs for --libs output
1292 Re-established OID record syntax application-xml. Nobody should use it
1293 but we don't want to change soname because of this symbol being absent.
1295 --- 3.0.42 2009/02/02
1297 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1299 Added member named_result_sets for init handler struct for the GFS. This
1300 allows a server to disable named result sets.
1302 Removed OID record syntax application-xml.
1304 Added support for rule-based transliterator for ICU wrapper of YAZ.
1306 Fixed bug #1902: yaz-icu XML output.
1308 Make YAZ checks Emacs friendly.
1310 BITSTRING value shows value. Bug #2346.
1312 ISO2709 decoding: skip control characters from indicator data.
1314 Omit sort key by default in yaz-icu's output.
1316 Allow combined single char options (again) for YAZ' options function.
1318 Utility yaz-marcdump got option to display YAZ version (-V).
1320 Allow YAZ to use ICU 3.4.
1322 Added new ICU test case which illustrates removal of diacritics.
1324 --- 3.0.41 2008/12/29
1326 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1328 --- 3.0.40 2008/12/29
1330 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1333 Fixed bug #2352: yaz-marcdump crashes for certain record.
1335 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1337 Added support for Danmarc2 to UTF-8 conversion.
1339 Added support for ISO5426 to UTF-8 conversion.
1341 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1342 implementation version.
1344 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1346 --- 3.0.38 2008/11/10
1348 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1349 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1351 ZOOM C now interprets databaseName option for ZOOM connection as path
1354 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1356 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1358 Dummy Libxml2 types no longer defined in headers of YAZ'.
1360 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1363 --- 3.0.36 2008/09/26
1365 Various ODR chapter fixes.
1367 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1369 Added missing source for Windows compilation, mutex.c.
1371 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1373 For SRU connections in ZOOM all records up to "count" are now fetched.
1375 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1376 in Windows due to bad error handling for Libxml2.
1378 Added facility for sending arbitrary records (ASN.1 any) using
1379 ZOOM C's Extended service update. Patch by Sam Reynolds.
1381 New options for ZOOM C's connection, logapdu which makes ZOOM log
1384 --- 3.0.34 2008/06/18
1386 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1388 --- 3.0.32 2008/06/12
1390 Fixed memory violation that could occur when decoding UTF-8. This bug
1391 was only present in 3.0.30 of YAZ.
1393 --- 3.0.30 2008/06/06
1395 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1396 GNU TLS is used by default (if found).
1398 yaz-ztest returns OPAC records if a client asks for OPAC.
1400 Improved speed of MARC-8 encoding.
1402 Added support for lossy and loss-less MARC-8 encoding.
1404 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1406 Added new Windows Service wrapper (sc).
1408 yaz-client's itemorder command may now send a file.
1410 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1412 Added new function yaz_log_xml_errors.
1414 Allow (but warn) unknown XML attributes in MARCXML parsing.
1416 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1418 The UTF-8 to MARC-8 conversion now uses a different set of characters
1419 for Greek symbols. Bug #2120.
1421 --- 3.0.26 2008/02/21
1423 Added yaz_daemon (daemon.h).
1425 Fixed bug #2068: pkg-config trouble
1427 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1429 --- 3.0.24 2008/01/28
1431 Document --with-xml2 option.
1433 Added OPAC XML XSD (etc/opacxml.xsd).
1435 Allow glob mask for name attribute in retrieval element for the
1436 generic frontend server's retrieval facility.
1438 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1439 except POLLIN/POLLOUT.
1441 Fixed error handling in cs_listen. Bug #2037.
1443 --- 3.0.22 2008/01/20
1445 Fixed version in yaz/yaz-version.h.
1447 Fixed bug #2027: Crash when closing connection.
1449 Changed configure so that ICU support is only enabled if only ICU
1450 and Libxml2 is available (because the ICU chain is XML based).
1452 --- 3.0.20 2008/01/15
1454 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1455 is built. Only this DLL depends on the ICU runtime.
1457 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1458 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1460 Changed license of CCL module to 'Revised BSD'. After consultation with
1461 remaining members of the original EUROPAGATE consortium, we are re-issuing
1462 the CCL module without a separate license. The software was developed by
1463 Index Data as part of a research project. The special license was included
1464 to help feed usage information back to the project consortium to support
1465 project evaluation. At this time, the project consortium has long-since
1466 disbanded, and the majority of the original principals have retired. At the
1467 same time, we have significantly modified the software during the following
1468 years, to the point where very practically no original code remains. To
1469 simplify re-use of the software, we have contacted those members of the
1470 consortium who could be reached, and agreed to re-issue the module as a
1471 proper part of the YAZ package.
1473 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1475 CQL closer to being version 1.2 compliant. CQL also allows free-form
1476 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1479 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1480 bug could make Extended services handling crash in the ZOOM layer. This
1481 bug was only present in YAZ 3.0.18.
1483 --- 3.0.18 2007/12/19
1485 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1488 yaz-marcdump reads and writes collection wrapped records.
1490 Handle OPAC for record conversion module.
1492 Fixes for ICU wrapper.
1494 Allow ICU libs to be controlled with --with-icu .
1496 --- 3.0.16 2007/11/12
1498 Added yaz_poll which is a wrapper for select/poll. When poll is available
1499 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1500 sockets to be in use.
1502 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1503 functionality through an XML based configuration (ICU chain). This system
1504 is useful for search facilities such as Pazpar2 and Zebra that needs to
1505 perform tokenization of indexed material. The ICU code in a separate
1506 library libyaz3_icu.a.
1508 Added HTTP tunnel facility for COMSTACK, bug #1752.
1509 This is a facility that allows a Web proxy, such as squid, to tunnel
1510 Z39.50 traffic. This facility is "transparent" to must applications
1511 using YAZ. It's enabled by using pseudo transport connect: followed by
1512 the proxy address, followed by command, then follwed by he regular
1513 "virtual" addresss. For example,
1514 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1516 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1518 --- 3.0.14 2007/09/21
1520 Fixed bad memory reference in ZOOM_record - cuased by member not being
1521 initialized. This was a problem only in YAZ 3.0.12.
1523 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1524 fields were not removed.
1526 Changed the way C code is generated from codetables.xml. Made a MARC-8
1527 conversion trie for each characterSet section rather than codeTable.
1528 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1529 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1531 --- 3.0.12 2007/09/12
1533 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1534 from ZOOM_record_error).
1536 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1538 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1540 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1542 Better SRW-to-Bib-1 diagnostic mapping.
1544 ZOOM C and yaz-client announces SRU version 1.2 by default.
1546 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1549 Fixed in yaz_sru_decode to allow other version than 1.1.
1551 --- 3.0.10 2007/08/22
1553 Added support for SRU scan for ZOOM.
1555 Added support for the use of the older versions or Extended Service
1556 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1557 set to the version , 1=first, 2=second, 3=third. The third version is
1558 what ZOOM C has used so far. And that, obviously, is the default.
1560 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1561 therefore in Zebra and in SimpleServer-based applications). The new
1562 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1563 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1564 which is passed into the back-end search callback function.
1566 Added support for HTTP Basic authentication in clients: the SRU/W
1567 codec encodes the username/password elements of the PDU structure
1568 appropriately, and these may be set using the "user" and "password"
1569 options in ZOOM-C applications (the same options that are used for
1570 Z39.50 authentication).
1572 --- 3.0.8 2007/06/25
1574 Fixed bug #1208: SSL appears to be broken in ZOOM.
1576 Fixed bug #1206: Libxml2 include path weirdness.
1578 Added oid_name_to_dotstring.
1580 Allow elementSetName to be specified for ZOOM C record update.
1582 Allow waitAction to be specified for ZOOM C based for Extended Services.
1584 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1585 syntax OID. Bug introduced in YAZ 3 series.
1587 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1589 --- 3.0.6 2007/06/06
1591 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1592 directory. yaz-client now reads commands from file given by option -f
1593 if specified; then tries to read .yazclientrc in current directory.
1594 Failing that, it reads .yazclientrc from user's home directory.
1596 Added support for correlationInfo Note and ID for Record Update via
1599 Added yaz-client command querycharset which specifies character set for
1600 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1601 (termListAndStartPoint).
1603 Charset ISO5428:1984 is an alias for ISO5428-1984.
1605 Implemented a way to perform scan in a result set using Z39.50. This
1606 is achieved by attaching the result set name in the characterInfo
1607 (type InternationalString) of OtherInformation in the Scan Request PDU.
1608 The result set is identified in the otherinformation by the new OID:
1609 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1610 This allows for scan in result set and faceted search . Zebra did some
1611 of this in the APT term using attribute type 8 and value being result
1612 set. Using the OtherInformation approach for this is cleaner and easier
1613 to work with in proxies and the like. This facility can be used in
1614 yaz-client using new command setscan which takes a result set as first
1615 argument, start position (APT) as second.
1617 Changed decoding of SRU XML packed records to deal with servers that
1618 have recordData with XML data with multiple root nodes. Also make
1619 comparison for recordPacking case insensitive. Again, one server
1620 returns "XML" where others return "xml".
1622 For SRU responses allow Content-Type application/xml as well as text/xml.
1624 --- 3.0.4 2007/05/21
1626 Fixed bug in character set conversion of BER strings. Bug introduced
1629 --- 3.0.2 2007/05/08
1631 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1633 For OID class, use oid_class consistently.
1635 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1638 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1639 character set for bibliographic information interchange". By Giannis Kosmas.
1641 Added documentation on new OID API.
1643 --- 3.0.0 2007/05/02
1645 Changes to generic frontend server interface: added new member
1646 'query_charset' for bend_initrequest structure. A backend init handler
1647 should set this member to its native character set for query terms.
1648 When defined, the frontend server logic will announce this character set
1649 to a client if the negotiationModel bit is set by the client. All server
1650 implementors are encouraged to specify this. If a backend server does not
1651 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1653 Added CCL utility to remove terms (stop words) from resulting RPN
1654 tree. This is handled by functions with prefix ccl_stop_words_ .
1656 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1657 terms in RPN queries.
1659 Clean-up the CCL API. Moved some internal structures from ccl.h to
1660 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1661 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1662 This is replaced by ccl_parser_find_str which takes a string instead.
1664 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1665 libyaz.la is the core of YAZ except the generic frontend server and
1666 does not depend on POSIX threads anymore. libyaz_server.la is the
1667 generic frontend server facilities and uses POSIX thread functionality
1668 if available. The libyaz.la no longer depends on POSIX threads because
1669 the number of global structures is limited. NMEM no longer re-uses blocks
1670 between threads ; it simply free's memory immediately but allocates in
1671 "large" chunks as usual. We don't expect any performance penalties
1672 because of this. The yaz_log system is still using a global log_level so
1673 caution must be taken when modifying it with yaz_log_init_.. +
1674 yaz_log_mask_str. This, however, should not cause any trouble because
1675 these functions are called during initialization of application code
1676 anyway. `yaz-config --libs server` returns libs for server applications;
1677 `yaz-config --libs` returns libs for non-server applications.
1679 New OID database - with public definitions in oid_db.h. Removed old OID
1680 database including the head oid.h and definitions such as enum oid_value
1681 and struct oident. The new OID database uses the same string names as
1682 before but the 'protocol' is gone. There are now only two representations
1683 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1684 converts from string to OID; functions with prefix yaz_oid_to_string
1685 converts the other way.
1687 Change to emit_term() in CQL-to-PQF query translation: when a term has
1688 the /regexp relation modifier, do not process it for leading and
1689 trailing "^" and "*", which have quite different meanings in regular
1692 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1693 write handlers no longer carries a 'last' parameter. This will make
1694 yaz_iconv flush "less" characters. A flush is performed by call to
1695 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1697 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1698 removed, because function yaz_query_to_wrbuf does the same.
1700 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1701 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1703 Deprecated MARC utility functions removed.
1705 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1708 Branch split: YAZ_2_1_55_branch
1710 --- 2.1.54 2007/03/16
1712 Fix to ZOOM-C so that transparent reconnection is properly handled on
1713 connections that are in asynchronous mode.
1715 Fixed compilation on OpenBSD 4.0.
1717 Large strings in GRS-1 records are now properly displayed in yaz-client.
1719 Added character conversion support for "advancegreek"; based on patch from
1722 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1723 sequence is met. Before the error was not set so it would be unknown.
1725 Adjust yaz-marcdump MARC reader so that it skips until record separator
1728 --- 2.1.52 2007/03/07
1730 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1731 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1732 fd_set structure used as a bitmask for the FDs to be selected on.
1734 Using ACX_PTHREAD macro to check for POSIX threads.
1736 Fixed have-vsnprintf check.
1738 --- 2.1.50 2007/02/23
1740 Fixes for configure on BSD. Bug #900.
1742 Added snprintf/vsnprintf wrappers for systems that don't have
1743 limits (heavens forbid).
1745 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1746 created before all previous tasks were completed and removed from the
1747 task queue, the new task could be removed by a mistake.
1749 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1751 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1753 Fixed bug #832: Problem with MARC/charset in yaz-client.
1755 Fixed bug #668: save command line history for yaz-client.
1757 Fixed bug #830: pkg-config support.
1759 --- 2.1.48 2007/01/23
1761 Extended ZOOM result set options with two options that may be read by
1762 a client: resultSetStatus and presentStatus with values as specified for
1764 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1766 Fixed bug #827: Using SSL fails on Debian etch.
1768 Fixed bug #826: Weird looking chars for set of MARC records.
1770 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1771 that is treated as an ItemOrder with itemRequest being an XML document
1772 external. The value of "doc" is the content.
1774 Extended the GFS search facility. New member of bend_search_rr
1775 'estimated_hit_count' signals that hits is known to be an estmate
1776 (higher or lower than real hit count). New member 'partial_resultset'
1777 signals that the search was partial (hit count is lower or equal than
1778 real hit count). For Z39.50, the information is stored in resultSetStatus
1779 member of SearchResponse APDU. For SRU, the information is signalled
1780 via SRU diagnostic 59: "Result set created with valid partial results
1783 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1785 --- 2.1.46 2007/01/13
1787 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1789 Added ZOOM_connection_peek_event.
1791 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1792 the following new functions:
1793 ZOOM_event_nonblock, ZOOM_connection_process,
1794 ZOOM_connection_get_{socket,mask,timeout},
1795 ZOOM_connection_fire_event_{timeout,socket}.
1796 The existing blocking event handler, ZOOM_event, is a wrapper for the
1797 + blocking ZOOM_event_sys_{poll,select}.
1799 Implemented function ccl_xml_config which parses XML version of CCL
1800 configuration (bug #798).
1802 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1804 Added timings utility (yaz/timing.h)
1806 --- 2.1.44 2007/01/03
1808 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1811 Fixed bug #779: Rotation of apdu.log fails.
1813 Fixed for character set conversions:
1814 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1815 Honor G1 set in MARC-8 decoding.
1817 --- 2.1.42 2006/12/17
1819 Fixed bug #775: char conversion does not handle Alternative UTF-8
1822 Implemented function yaz_marc_read_line which parses MARC line format
1823 records. There is a wealth of formats out there. So far, this function
1824 reads line records produced by yaz_marc_write_line.
1826 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1827 more generic and easier to remember(!) options: -i format and -o format
1828 which specifies input format and output format respectively - where
1829 format is one of "marc", "marcxml", "line", "marcxchange".
1831 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1832 does not print anything except warnings for records.
1834 For yaz-marcdump, added support for MARC split into files (-s) with a given
1837 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1838 spec, at http://www.loc.gov/standards/sru/record-update/
1839 This has changed the binary layout of the following structs:
1840 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1841 bend_update_rr . Patch by Ko van der Sloot.
1843 Added GFS utility function bend_assoc_is_alive which returns 1 if
1844 association is still alive (client is connected); 0 otherwise (client
1845 closed connection). This allows busy servers to stop working for
1848 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1849 been a separate piece of software. This version of ziffy has been modified
1850 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1852 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1854 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1855 Client code may now interrogate options such as "init_opt_sort" to
1856 find out whether the server claims to support various options.
1858 --- 2.1.40 2006/11/27
1860 Added utilities yaz_{set,get}_esn to set/get element set name from
1863 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1864 of YAZ and has been so since YAZ 2.1.10.
1866 Implemented ZOOM_record_error which returns error information for
1867 record (surrogate diagnostic).
1869 --- 2.1.38 2006/10/31
1871 Updates for SRU Update by Ko van der Sloot:
1872 1. Changed name from "operation" to "action"
1873 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1874 versions in the code, marked as 'backward compatible'.
1875 3. Added diagnostics for SRU Update.
1877 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1879 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1881 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1883 For GFS, fixed problem with SRU diagnostic 'First record position out of
1884 range' being issued for 0 hits.
1886 zoomtst10 part of Windows Build.
1888 --- 2.1.36 2006/10/13
1890 Implemented yaz_filepath_comp which splits a path into file path
1891 components (required by Zebra 2.0.3+).
1893 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1894 BSD inspired license until now so this should not have any real impact on
1895 anybody. See http://www.opensource.org/licenses/bsd-license.php
1897 Fixed bug #687: Missing log lines.
1899 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1902 Fixed bug #689: SRU diagnostics to be added.
1904 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1905 whether a connection is idle (no more work do do).
1907 --- 2.1.34 2006/10/04
1909 Change type of optval from long to int for invocation of setsockopt with
1910 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1912 Added support for specifying the max log file size for the Generic
1913 Frontend Server. The size is given with option -r.
1915 --- 2.1.32 2006/09/21
1917 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1919 --- 2.1.30 2006/09/17
1921 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1924 Fixed bug in Generic Frontend Server that could cause a server to stop
1925 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1927 For the generic frontend server, the maximum record size is used as maximum
1928 size of incoming packages (SRU + Z39.50). The value until was previously
1929 only used in Z39.50 Init negotiation and, later, in a session controlled
1930 sizes of records returned. This is controlled using -k option. It can be
1931 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1933 --- 2.1.28 2006/09/04
1935 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1938 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1940 New option for yaz-marcdump -lpos=value which allows setting a portion
1941 of MARC header to a certain value.
1943 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1945 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1946 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1948 --- 2.1.26 2006/08/15
1950 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1953 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1955 --- 2.1.24 2006/08/08
1957 Fixed MARC ISO2709 encoding routines to deal with character set
1960 Minor changes to GFS logging. Database included in search request log
1963 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1964 cached/multiple records.
1966 Shared libraries are built by default on Unix+configure.
1968 Changed cql2pqf transformation to use a different evaluation order. The
1969 new order is: always, relation, structure, position, truncation, index
1970 and relationModifier. Old order was: always, relation, relationModifier,
1971 structure, index, position, truncation. Note that the the latter ones
1972 override former ones for identical attributes.. The new scheme means that
1973 it is possible to override any existing attribute with a relationModifier.
1974 And also that it is possible to override everything for the index rule
1975 (except the ones listed in relationModifier). No order is perfect but this
1976 one, we believe, covers more real cases.. The "always" should have been
1977 called "default", since the attributes there can be overridden with all
1980 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1981 compilation phase, but also for yaz-config --cflags output. This allows
1982 us to have public headers with Libxml2 stuff in them . It should also,
1983 eventually, make Libxml2 checks redundant in packages using YAZ, such
1986 --- 2.1.22 2006/06/15
1988 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1989 stored in uri, message and details.. Previously diagnostics were stored
1990 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1991 compatibility.. but he's probably the only one affected, so.
1993 Added support for CCL, compiled on the client side, in ZOOM-C. This
1994 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1995 input; the resulting query objects can be used for for searching with
1996 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1998 YAZ' configure searches for OpenSSL by default.
2000 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2001 SL_CTX_use_certificate_file. See
2002 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2003 for more info. Thanks to Ko van der Sloot.
2005 --- 2.1.20 2006/06/02
2007 Bug #600: SRU GET, POST support for yaz-client. Introduced
2008 command 'sru' which selects method SOAP/GET/POST.
2010 Allow missingValueAction to be specified for the sortspec string -
2011 function yaz_sort_spec. By default, the missing value action is null.
2012 Use ! to specify "abort". Use = followed by stringvalue to specify default
2015 Ensured that Present-handler (if defined) is called in GFS before any call to
2016 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2017 searchRetrieve requests.
2019 Documentation for YAZ is now based on the Docbook XML/XSLT using
2020 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2021 is no longer depending on jade/openjade or docbook-to-man scripts.
2022 PDF is no longer part of the distribution - but can optionally be
2023 made using DSSSL/jadetex or FOP.
2025 Added retrieval handling support in Generic Frontend Server to support
2026 conversion between MARC/XML as well as XSLTtransforms. See
2027 etc/yazgfs.xml for an example.
2029 Added Authentication support to Generic Frontend Server in SRU
2030 mode. Authentication using HTTP Basic is supported, as is the use
2031 of 'x-username' and 'x-password' parameters in the request itself.
2033 Added support for a new character set MARC8s identical to MARC8 except
2034 that it converts combined characters to single Unicode characters in the
2035 Latin-1 range (when possible).
2037 --- 2.1.18 2006/04/24
2039 ASN.1 compiler 0.4: generates brief Doxygen file header for
2040 generated .h/.c files.
2042 Utility yaz_iconv now supports conversion to MARC-8.
2044 New facilities for the MARC module. The reading - and writing of
2045 content are separate methods for the yaz_marc_t handle. The following
2046 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2047 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2048 format). Write functions have prefix yaz_marc_write_.. The existing
2049 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2050 available. Removed support for OAI-MARC and simplexml (not the
2051 simplexml from PHP5).
2053 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2054 to be returned for this connection.
2056 --- 2.1.16 2006/03/31
2058 Allow multiple languages and charsets to be specified with
2059 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2060 negcharset iso-8859-1,utf-8
2062 Translation of proximity nodes from CQL into PQF now works.
2064 Moved to automake 1.8, 1.9.
2066 Added function yaz_log_set_handler which allows a log handler to be
2067 installed. This handler will be called for all log messages. Output
2068 to file is also produced; but that can be disabled by passing NULL
2069 fname to yaz_log_init_file.
2071 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2073 For SRW (including GFS), accept application/soap+xml as content-type
2076 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2077 produces NO stylesheet reference even if a default stylesheet is specified
2080 --- 2.1.14 2006/03/14
2082 Updated Windows package to include yazd.dll + yazd.lib for the
2083 Development component.
2085 If the environment variable YAZ_LOG is set, then it is used as a
2086 string indicating the default level of logging to use if not
2087 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2088 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2089 used as before. So, for example, to omit warnings from YAZ logging,
2090 export YAZ_LOG=-warn
2092 cql_transform() now map structure and other attributes before indexes,
2093 so that index-specific structures and other attributes can override
2094 defaults. So now a combination of mapping specifications such as:
2096 index.dc.date = 1=date-modified 4=5
2097 does the right thing.
2099 cql_transform() now also respects the "always" mapping specification,
2100 which establishes an initial set of attributes to be used for all
2101 terms except where overridden by more specific attributes associated
2102 with the index, relation or modifier.
2104 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2105 which mode to use; one of "post", "get" or "soap" (SRW, default).
2107 Fixes for yaz_iconv routines: changed trie-based character set conversions
2108 to use only non-negative values for bit fields due to Sun's C compiler not
2109 supporting negative values.
2111 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2112 sequences where not read correctly. Fix by Rustam Usmanov.
2114 Updated win/makefile to use options, settings which makes things
2115 compile with VS C 2005.
2117 --- 2.1.12 2006/02/01
2119 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2121 In ZOOM socket code, use select instead of poll on MacOSX.
2123 ZOOM-C now support client-side compilation of CQL into RPN that is
2124 sent to the server, enabling CQL to be used against all Z39.50
2125 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2126 ZOOM_query object, and submit it using ZOOM_connection_search().
2127 The CQL-to-RPN translation uses a configuration file, the name of
2128 which must be specified in the Connection's "cqlfile" option.
2130 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2131 function, which takes as its start-term parameter a ZOOM_query object
2132 (which may have had either CQL or RPN set into it).
2135 --- 2.1.10 2005/11/29
2137 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2138 GFS to support this as well. Backend handler, bend_srw_update, does the
2139 update work. Code contributed by Ko van der Sloot.
2141 Allow retrieval of Search Result-1 information in ZOOM by the use of
2142 options that are attached to a result set. ZOOM documentation updated
2145 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2146 UTF-8 conversion. Patch by Raj Patel.
2148 Added option -m to GFS to control formatting of timestamps in log file.
2150 Added 'exit' as synonym for 'quit' in yaz-client
2152 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2153 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2154 for the new members. Patch by Ko van der Sloot.
2156 Added support for SRU POST. It is supported for content-type
2157 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2159 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2160 Instead make the library libyaz.la multi-threaded. Threading as a whole
2161 can still be disabled by configure option --disable-threads. Previosly,
2162 with older GLIBCs there were problems with MT libs under Apache. This
2163 has now been fixed a long time ago.
2165 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2168 CQL module modified to be case insensitive for relations/indexes/operations.
2170 Fixed bug in CQL transform code: incorrect value relationModifieder
2173 Added 'show all' command for yaz-client which retrieves all results
2176 Added new yaz-client, xmles, which takes a (private) OID and
2177 a document to be sent as an extended service request.
2179 Describe new yaz-client commands wait_response and set_auto_wait.
2181 Increase TCP/IP listener backlog from 3 (which I am guessing was
2182 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2183 that the socket will queue as many incoming connections as it's able
2184 to handle ongoing connections. In other words, it will never now
2185 refuse a connection that it would be able to handle merely because
2186 it's not got around to accepting() enough of the pending connections
2187 yet. This is the behaviour anyway under Linux, where the listen()
2188 argument is ignored; but not under BSD and on systems such as
2189 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2190 YAZ-based servers should now be uniform across operating systems in
2193 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2194 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2195 This allows yaz-marcdump to read large MARC batches (>2 GB).
2197 Modified all YAZ source files - except the source which is auto-generated
2198 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2201 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2202 corresponding to the existing *_setl() function. These allow option
2203 values containing arbitrary valuues.
2205 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2206 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2207 except that it returns an indicator of whether or not the sort
2208 criterion was accepted (0 for OK, -1 for invalid).
2210 --- 2.1.8 2005/06/07
2212 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2213 MARC output rather than returning "new" buffer.
2215 yaz-client warns about unknown init options.
2217 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2219 --- 2.1.6 2005/05/24
2221 Added support for SRW sort in Generic Frontend Server. Patch
2222 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2223 sortKeys - or NULL if none is provided.
2225 Fixed bug #307: It was impossible to specify indefinite/no timeout
2226 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2229 Added support for multiple languages and charsets to be specified in
2230 ZOOM. Each charset/language is separated by a blank. If negotiation is
2231 in effect in init-response, Option
2232 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2233 Code based on patch by Vasiliy Osadchuk.
2235 Fixed bug #306: infinite recursion that occurred when calling
2236 yaz_log_level_init as the first call (before other log level or
2239 Fixed bug in scan handling in front end server: if preferred-Position-In-
2240 Response was non-present, a NULL pointer referece was performed.
2242 --- 2.1.4 2005/04/26
2244 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2245 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2246 now defined for all those error codes. So instead of putting 109 in
2247 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2248 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2250 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2253 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2255 Program yaz-client now exits and produces an error message if multiple
2256 Z39.50 servers are specified on the command line (none or one allowed
2259 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2262 --- 2.1.2 2005/03/16
2264 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2266 Fixed bug #272: Preserve spacing for CCL terms.
2268 --- 2.1.0 2005/03/14
2270 Added support for virtual hosts and multiple backend servers for
2271 the YAZ frontend server. The configution is XML based and
2272 support specificition of CQL to RPN mappings and explain information.
2273 See section "Virtual Hosts" in the YAZ manual.
2275 Extended OPAC display utility. OPAC display utility renders
2276 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2277 to supplement yaz_marc_decode_wrbuf.
2279 Fixed a bug in MARC decoder that could caused it to crash for some
2280 invalid MARC records. More diagnostics and warnings where added in
2281 XML output (warnings, etc are stored in comments).
2283 --- 2.0.34 2005/02/08
2285 Fixes for UNIX domain sockets. Bug #261.
2287 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2289 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2290 Added yaz_marc_subfield_str which defines subfield lead string which is
2291 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2292 yaz_marc_endline_str which defines end of fields string used in
2293 YAZ_MARC_LINE format. Default string is newline.
2295 Experimental support for MarcXChange. This format can be produced
2296 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2297 http://www.bs.dk/standards/MarcXchange.xsd
2299 Added yaz-client commands scansize that sets maximum number of
2300 entries to be returned by scan.
2302 --- 2.0.32 2005/01/11
2304 Added support for SRW scan in yaz-client and Generic Frontend Server.
2306 * Added whereInList member to SRW Scan Term.
2308 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2310 Fixed NMEM system to return aligned blocks on the smallest boundaries
2311 that are suitably aligned for all possible types on the particular
2312 architecture YAZ is being built for.
2314 --- 2.0.30 2005/01/04
2316 Fixed numerious warnings that was issued with newer versions of GCC.
2318 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2319 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2322 Make YAZ Generic Frontend Server slightly faster.
2324 Enhance (and reduce) logging for Generic Frontend Server.
2326 Revert YAZ log system so that it flushes every write operation
2327 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2329 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2330 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2331 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2332 will effectively disable old definitions.
2334 --- 2.0.28 2004/11/09
2336 Added yaz_log_time_format which specifies log format using
2339 Added yaz_log_module_level which returns mask for a module. Value
2340 is non-zero mask a if module is enabled; zero if disabled.
2342 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2343 in include/yaz/cql.h.
2345 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2347 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2349 Fixed bug #172: RPM builds does not enable SSL.
2351 Doxyfile.in part of dist. Doxyfile generated by configure.
2353 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2354 are given and the corresponding component does not exist.
2356 Extend CCL documentation in YAZ reference. Describe r=r.
2358 --- 2.0.26 2004/10/01
2360 Fixed MARC->MARCXML conversion to properly deal with
2361 fields, subfields, indicators having non-ASCII characters.
2363 Fixed MARC->MARCXML conversion so that ASCII control characters
2364 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2367 Added YAZ GFS support for conversion from Z39.50 surrogate
2368 diagnostics to SRW surrogate diagnostics.
2370 Bug fix: YAZ GFS did not return schema in explainResponse.
2372 --- 2.0.25 2004/09/30
2374 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2375 now converts recordSchema to elementSetName as well as schema URI.
2377 Fixed bug in COMSTACK that prevented HTTP request packages from being
2380 --- 2.0.24 2004/09/29
2382 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2383 does not require white-space before and after the dash in a range, e.g.
2384 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2387 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2388 due to new GCC removing "redundant" code.
2390 Added yaz-client commands scanpos and scanstep that sets preferred
2391 position and step-size for scan.
2393 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2395 Added CCL utility ccl_qual_buf which parses one or more CCL
2396 spec lines in a buffer.
2398 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2399 of name and value - ignoring empty lines and comments.
2401 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2403 Added odr_get_element_path which returns current element path for an
2404 ODR handle. This utility is useful in error handling or user-defined
2407 Added ODR_PRINT utility odr_set_stream which is is a more generic
2408 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2409 to a write function and pointer to close function. The close function - if
2410 non-NULL - will be called during odr_destroy.
2412 Fixed bug in CCL parser where truncation char was not removed from
2413 right side when truncation=both was in effect.
2415 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2418 --- 2.0.23 2004/08/11
2420 Fix buffer overrun in CQL parser when dealing with proximity (%).
2422 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2423 to UTF-8/UCS conversion is now only based on codetables.xml.
2425 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2427 --- 2.0.22 2004/08/06
2429 Add support for more "commit changes" in ZOOM (uses Extended Services).
2431 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2434 Yet another small fix for configure of SSL.
2436 --- 2.0.21 2004/05/14
2438 Fix SSL libs for configure when --with-openssl=DIR is given.
2440 --- 2.0.20 2004/05/10
2442 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2444 SSL comstack now uses yaz.pem certificate file on server side
2445 by default. Certificate filename can be configured by calling
2446 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2448 Fix bug regarding multiple calls to ZOOM_connection_connect.
2450 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2452 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2453 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2455 ZOOM now allows inspection of X509 peer certificate for verification.
2456 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2458 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2459 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2460 as "modular" but it simplifies things.
2462 Added cs_get_peer_certificate to that returns peer X509 PEM.
2464 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2465 NULL if SSL is unavailable.
2467 Documentation about MARC decoding tools.
2469 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2471 --- 2.0.19 2004/03/30
2473 Rename CHANGELOG to NEWS to follow GNU style packing.
2475 Fix bug with missing initialization of member in init_diagnostics.
2476 This bug affects threaded version of GFS server.
2478 --- 2.0.18 2004/03/20
2480 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2483 Ensure zlib.dll is packed with Windows install.
2485 --- 2.0.17 2004/03/17
2487 Fix encoding of xsd:string to use text instead of CDATA.
2489 Fix endless loop in CQL parser with unbalanced ".
2491 Use a more compact way to store MARC-8 conversion tables.
2493 --- 2.0.16 2004/03/16 Debian only
2495 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2498 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2503 --- 2.0.15 2004/03/01
2505 Another fix for decoding of XML packed records.
2507 --- 2.0.14 2004/02/25
2509 Fixes for Chunked encoding. White space not ignored after length spec.
2511 Update NS and use default NS for SRW diagnostic elements.
2513 --- 2.0.13 2004/02/23
2515 Implement ZOOM_resultset_cache_reset which resets record cache.
2517 Implement ZOOM_resultset_sort which sorts a result set.
2519 Implement chunked HTTP transfer.
2521 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2523 --- 2.0.12 2004/02/16
2525 Added member 'schema' to bend_explain_rr structure so that backend
2526 can specify explain record identifier. Defaults to Zeerex 2.0.
2528 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2530 --- 2.0.11 2004/02/16
2532 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2535 Added init command for yaz-client which sends "extra" init request.
2537 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2538 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2540 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2542 Make ZOOM error code for "invalid query".
2544 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2546 --- 2.0.10 2004/02/05
2548 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2551 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2553 Added option -p <file> to make Generic Frontend Server to write PID file.
2555 Added option -D to put Generic Frontend Server in background on its own.
2557 Make ZOOM C recognize option "password". If unset, "pass" is used
2558 (for backwards compatibility).
2560 Fixed a bug in Generic Frontend Server that could make it crash if a
2561 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2564 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2565 Must be issued before open, in order to be in effect.
2567 --- 2.0.9-6 2004/01/12 Debian/Windows
2569 Make the SRU server more picky WRT unknown params, etc.
2571 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2573 New YAZ client command, options, that sets Z39.50 options.
2575 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2576 options from a string of tokens (one token for each option bit).
2578 Update SRW diagnostic code messages.
2580 --- 2.0.9-5 2004/01/07 Debian/Windows
2582 Handle user defined stylesheet for SRW/SRU.
2584 --- 2.0.9-4 2004/01/06 Debian/Windows
2586 Fix bug in decoding of Content-Length.
2588 --- 2.0.9-3 2004/01/06 Debian/Windows
2590 Fix a bug with decoding of XML packed records.
2592 --- 2.0.9-2 2004/01/05 Debian only
2594 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2596 Fix bug in SRW/SRU diagnostics decoding.
2598 --- 2.0.9 2004/01/05
2600 Fixed bug in Generic Frontend Server which could drop records exceeding
2601 preferred message size. Reported and fixed by Irina Dijour.
2603 Fixed calculation of package size for structured records in Generic
2604 Frontend Server. Reported and fixed by Irina Dijour.
2606 Fixed namespace for SRW/SRU diagnostics.
2608 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2610 --- 2.0.8 2003/12/22
2612 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2613 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2616 CQL changes to reflect recent changes to the specification:
2617 * Documentation talks about context sets instead of index sets.
2618 * Documentation talks about indexes instead of qualifiers.
2619 * The CQL-to-PQF transformer's configuration file now uses
2620 "index.set.name = <attributes>" instead of the old form
2621 "qualifier.set.name = <attributes>". (Both forms are still
2622 understood but the latter is deprecated.)
2623 * CQL terms with no explicit index specified are now interpreted as
2624 cql.serverChoice instead of srw.serverChoice (which of course
2625 behaves exactly the same.)
2627 --- 2.0.7 2003/12/16
2629 MARC conversion can now generate ISO2709 output in another
2630 character set. yaz-marcdump uses this facility if you invoke it
2633 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2634 functions from there can be used from C++.
2636 --- 2.0.6 2003/12/04
2638 Frontend server now transfers memory from decoded packages to stream
2641 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2642 references to show up.
2644 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2645 the ZOOM Abstract API. The older names for the same options are still
2646 also supported for the benefit of old applications.
2648 ZOOM-C supports "implementationId" and "implementationVersion" options
2649 to go along with "implementationName". These allow the user code to
2650 specify identification strings to be sent to servers.
2651 Add OID for the new ExtLite attribute set.
2653 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2654 as requested/supplid by Ere Maijala <ere@atp.fi>
2656 For generic frontend server, reverse the order of
2657 "toolkit-supplied / application-supplied" strings sent as implementationId,
2658 Name and Version. Also, remove the spaces around the slash. This brings
2659 the GFS in line with the behaviour of ZOOM-C on the client side.
2661 Add function ZOOM_scanset_display_term.
2663 yaz-client shows scan displayTerm if present.
2665 Utility yaz-iconv is now installed by default along with the man page
2668 Extend configure check for OpenSSL to use pkg-config where available (such
2671 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2672 server to specify uid/gid/mask for socket using the format
2673 unix:[user=uid,][group=gid,][umask=mask,]file=path
2674 If file= is omitted the existing format is assumed, e.g.
2676 in which case the mask is 0666 (rw for everybody).
2678 Major restructure of YAZ source. All source in libyaz is in src directory.
2679 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2680 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2682 Added man page for utility yaz-marcdump (used to be called marcdump).
2683 yaz-marcdump is installed by 'make install'.
2685 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2686 of incoming package failed.
2688 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2690 Change prototype of odr_perror: add const to message string.
2692 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2694 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2695 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2696 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2697 DNS lookup. There should not be any compatibility problems with this
2698 assuming that blocking=1 or 0 is used.
2700 Fix bad reference in UNIX comstack in function cs_addrstr.
2702 Fix for compilation on AIX.
2704 The generic front-end server (server/seshigh.c) now supports returning
2705 Init diagnostics to the client in User-information-field, in
2706 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2709 --- 2.0.4 2003/09/04
2711 Allow any CQL relation (not just all,any,exact,scr).
2713 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2714 that features the same UI.
2716 Implemented command update0 in YAZ client which is equivalent to
2717 update but uses old of Ext Update ASN.1.
2719 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2720 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2721 Previously no OID was used for this info.
2723 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2724 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2725 returns 'malformed search term' otherwise.
2727 SortResponse member resultCount now set to NULL in sort handler of
2730 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2733 Add three new utility functions for translating OIDs between various
2734 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2735 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2736 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2737 char *oid_to_dotstring(const int *oid, char *oidbuf);
2738 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2740 Reverted modifications for ES Update definition for z_IU0Update
2741 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2742 is back to YAZ 2.0.2.
2744 String value attributes for CCL parser.
2746 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2747 which their FirstSearch server returns in Init responses, sometimes
2748 carrying useful diagnostic information when Init fails. This has the
2749 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2750 "z39.50/oclcui.asn", where its definition is somewhat different from
2751 what OCLC document on their web-site, as required to interoperate with
2754 Support for anonymous authentication in yaz-client. Use the command
2757 * Fix the OID of the Index Data-local "admin" Extended Service from
2758 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2759 the 1000, which indicates a locally-defined OID, was a mistake.
2761 --- 2.0.3 2003/06/20
2763 Fix CCL directive @case handling so that it affects string match for
2764 both CCL keywords and qualifiers.
2766 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2767 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2768 Decoder has been updated with ASN.1 changes as listed in
2769 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2770 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2771 z_IUUpdate, remains unchanged.
2773 ZOOM_record_get may now return a record in a specific character set.
2774 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2775 "from" is the character set of record as returned by target. "to" is
2776 the character set to be returned. If omitted, "to" is UTF-8.
2778 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2780 New ODR utility, odr_getelement, which returns name of element for
2781 which encoding/decoding failed.
2783 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2784 in cases where a required element was omitted.
2786 Bug fix: some MARC8 sequences were not converted.
2788 New ZOOM option "step" which specifies number of records to be
2789 retrieved in one chunk. Used in conjunction with "start" and "count".
2791 SRW support for yaz-client. Use scheme http: to use it, e.g.
2794 yaz-client no longer does (un)intelligent character set conversions
2795 by default. Can be enabled with charset and marc_charset commands.
2797 xmalloc trace fix for 64-bit systems such as DEC alpha.
2799 Solaris 2.6 compile fix.
2801 New function, cql_strerror() translates SRW error codes, as returned
2802 by cql_transform_error(), into human-readable English strings. Used
2803 in yaz-client diagnostics when appropriate.
2805 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2806 converts it into a type-1 query which is sent to the server. This
2807 makes CQL available for use with all Z-servers, as opposed to the tiny
2808 minority that can handle CQL queries themselves.
2810 --- 2.0.2 2003/04/28
2812 New Debian package layout similar to the Redhat Package layout.
2814 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2815 and search result respectively.
2817 --- 2.0.1 2003/04/25
2819 Redhat package is now several packages: libyaz (runtime libraries),
2820 libyaz-devel (development and documentation, and yaz (utility programs).
2821 Package spec file by Morten Bogeskov.
2823 New member 'schema' in struct bend_fetch_rr which the name of requested
2824 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2825 handler MAY set this to reflect the schema of the returned record.
2827 New member 'display_term' in struct scan_entry. GFS now sets member entries
2828 and allocates scan entries to be filled by user scan handler. In previous
2829 version, entries member was allocated by the scan handler. That still works,
2830 but the GFS will ignore member display_term - assuming it was NOT set by
2831 the handler. The fact that the GFS now allocates the entries both allows
2832 for new members and makes a scan handler easier to write.
2834 Fix CQL lex buffer overflow.
2836 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2837 SRU default recordPacking is string.
2839 SRU protocol support for frontend server.
2841 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2843 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2845 Added scan for the ZOOM shell (zoomsh).
2849 * String Identifers for Schemas (Amendment 5).
2850 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2851 Old definition for schema
2852 Odr_oid *schema; /* OPT */
2857 Z_InternationalString *uri;
2858 #define Z_Schema_oid 1
2859 #define Z_Schema_uri 2
2862 * resultCount parameter to Sort Response (Amendment 1).
2863 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2865 Support for SRW 1.0 over HTTP. This is an optional feature and
2866 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2869 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2870 on the same port. SRW SearchRetrieveRequests are mapped
2871 to bend_init,bend_search,bend_fetch,bend_close.
2873 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2875 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2876 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2878 ZOOM connections are SRW based if schem http is used for hostname
2879 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2880 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2882 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2883 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2884 distance=n, order=true/false, relation=le, prox unit=word. If
2885 n is omitted, distance 1 is used.
2887 Fixed problem with C compiler include path in wrong order.
2889 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2890 on Solaris. Patch from Ko van der Sloot.
2892 New MARC decode API. All new functions operate on a yaz_marc_t
2893 handle. The most important new functions are: yaz_marc_create,
2894 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2895 decode and destroy respectively. Decoder can produce formats
2896 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2897 include/yaz/marcdisp.h.
2899 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2900 to UTF-8, UCS-32, wchar_t or Latin-1.
2902 * Prototypes for yaz_iconv_-functions moved to separate header
2903 include/yaz/yaz-iconv.h.
2905 Make a few private functions 'static' in unix.c. This prevents
2906 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2908 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2909 are set when Init Response is received.
2911 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2912 but returns diagnostic set as well.
2914 New function yaz_strerror which is a portable wrapper for
2915 strerror/strerror_r/GetLastMessage.
2917 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2918 is returned for MARC. If type is "oai", then OAI MARC is returned.
2920 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2923 --- 1.9.2 2002/11/26
2925 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2927 Fix bad race conditions on SIGTERM and terminate gracefully in
2930 Move retrieval (data1) module to Zebra since nobody seems to be
2933 Add GRS-1 render for ZOOM using same format as yaz-client.
2935 --- 1.9.1 2002/10/05
2937 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2939 Fix broken ESpec handling in data1 module.
2941 SGML reader parses comments and makes them part of the data1 tree.
2943 Added several type casts so that YAZ compiles as C++ code.
2945 ZOOM didn't handle PDU encoding failures properly.
2947 Added more Bib-1 diagnostics (approved extensions).
2949 GNU configure: better check for iconv.
2951 More portable use of accept, getpeername. Check for socklen_t. Use
2952 int/size_t if socklen_t is not defined.
2956 PQF parser rejects bad queries - including those with extra
2957 characters in them. PQF parser used to silently ignore that.
2958 Cleaner API for PQF added, which allows you to get detailed
2959 error information for bad queries (see yaz/pquery.h).
2961 Fixed bug in ZOOM_record_get for type "database".
2963 Implemented mini iconv library supporting conversions between
2964 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2966 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2968 --- 1.8.9 2002/08/20
2970 Fixed ZOOM C record cache so that preferredRecordSyntax and
2971 elementSetName is used to check for already fetched records.
2973 --- 1.8.8 2002/08/02
2975 Added three members in bend_initrequest structure to facilitate
2976 character set negotiation.
2978 Fixed a bug in frontend server that could cause indefinite
2979 loops under rare conditions.
2981 Revised character set utilities (charneg.h) so that encoding
2982 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2984 For PQF, directive @term <type> sets term type for Scan/Search.
2985 Here <type> is general, string, numeric, null. The term type
2986 is inherited - just like @attr.
2988 New call odr_set_charset that sets character set conversion for
2989 international-strings on a ODR stream. Prototype is:
2990 int odr_set_charset(ODR o, const char *to, const char *from);
2991 The InternationalString is still represented as C string in YAZ
2992 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2993 won't). On the protocol level, you can use any encoding.
2995 Support for UNIX sockets in ZOOM.
2997 Solaris recv sometimes returns errno == ENOENT. It is treated as
2998 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3000 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3001 both client and server. Code by Morten Bogeskov.
3003 --- 1.8.7 2002/05/22
3005 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3006 that they can be used directly from Visual Basic. You must recompile
3007 your windows APP if you're using ZOOM.
3009 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3010 Commands "lang" and "charset" sets language and character set respectively.
3011 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3012 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3014 Attributes from multiple CCL fields may be OR'ed rather than merged
3015 using directive "@field or". Fields are still merged by default -
3016 equivalent to "@field merge".
3018 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3021 Fixed bug in zget for parameter ExtendedServicesResponse.
3025 --- 1.8.6 2002/03/25
3027 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3029 Client displays USR.1:SearchResult-1 (hits per term).
3031 Additional Search Info for search in Generic Frontend Server.
3033 Fixed CCL parsing of "field=s".
3035 WIN32 installer - using the excellent NSIS software from nullsoft.
3037 Fixed CCL parsing of "field = - <number>".
3039 Added function yaz_marc_decode that decodes MARC for line mode
3040 display or XML (similar to that used by JZKit).
3042 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3043 Z39.50. But ISO/ILL was, however.
3045 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3046 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).

3051 --- 1.8.5 2002/02/03
3053 New YAZ client features: Command completion and new commands:
3054 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3055 Code provided by Jacob Poulsen.
3057 New call oid_trav, that visits all registered OIDs via callback.
3059 Function ZOOM_record_get now returns const char pointer rather than
3060 void pointer. It saves a lot of type casts.
3062 For YAZ client, command "auth" now allows you to set authentication
3063 in IdPass style. It is enabled when three tokens are given - order
3064 is user, group and password.
3066 Fix memory leaks in MARC record handling for ZOOM.
3068 New option for YAZ client, -k <kilobytes> that sets
3069 maximum record size. Similar to -k option for generic frontend
3070 server and yaz-ztest.
3072 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3074 Prefix query parser reports "fail" when bad attribute set is given.
3076 Fix in MARC decoder. Proximity logging. Fix for attribute set
3077 in scan handler for server. Patches by Shigeru Ishida.
3079 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3082 Configure option --with-openssl=<dir> now works when a directory is
3083 specified. Patch provided by Morten Bogeskov.
3085 New option for YAZ client, -u <auth>, that sets authentication.
3087 ZOOM fix: error information was sometimes "missing", since error
3088 was cleared/reset too when it shouldn't.
3090 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3092 --- 1.8.4 2002/01/04
3094 Scan for ZOOM API. New object ZOOM_scanset. New functions
3095 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3096 ZOOM_scanset_destroy.
3098 New ZOOM function, ZOOM_connection_last_event, that returns type
3099 of last event (such as "receive data", "send data", "apdu received",
3102 New ZOOM option, schema, that specifies schema for retrieval.
3104 New CCL feature. Qualifiers can be aliases for one or more
3105 other qualifiers (if more than one is given, OR is used).
3107 ZOOM uses named result sets if target supports it.
3109 Two new YAZ client commands: . (dot, which sources a script of YAZ
3110 client commands), and ! (to execute shell command.). Implemented
3113 Working on Debian packages.
3115 --- 1.8.3 2001/11/19
3117 YAZ client enables named result sets only if target supports it.
3119 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3121 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3122 with key="host" to get same result.
3124 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3125 Function Z3950_resultset_record(s) returns references to records
3126 "owned" by resultset. To become owner use Z3950_record_clone.
3128 Function z_ext_record handles Extended Services. Thanks to
3131 --- 1.8.2 2001/11/12
3133 CCL Parser fix: ignore token comma when dealing with and-lists.
3135 Documentation updates for COMSTACK.
3137 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3138 Changed prototype Z3950_records. For some functions, int parameters
3139 were changed to size_t.
3141 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3144 New MARC decode/display function, marc_display_exl, which properly rejects
3145 non-ISO2709 records. YAZ client uses it.
3147 --- 1.8.1 2001/10/29
3149 Fix bug: local attribute set wasn't set correctly in PQF strings.
3153 * Old Z39.50 codecs no longer supported.
3155 Added ZOOM C binding. See http://zoom.z3950.org/
3157 Renamed states for COMSTACKs to avoid confusion with events.
3159 Implemented cs_look and proper cs_rcvconnect.
3161 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3163 Configure detects POSIX threads on OpenBSD.
3165 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3166 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3168 When error is returned from present handler, non-surrogate diagnostic
3169 is returned in present response (and fetch handler is no longer called).
3171 * Minor adjustments to pquery parser (PQF). Token characters may be
3172 escaped by using backslash (C-style).
3174 PQF parser allows string attribute values to be specified. For @attr,
3175 non-numeric characters after the equal-sign are treated as strings
3176 (e.g. @attr 9=title).
3178 CCL trunction character may be defined (@truncation in file)
3180 * function zget_ExtendedServicesRequest sets waitAction to
3181 waitIfPossible (was wait).
3183 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3186 CCL operator names may be set in field definition files (CCL_bibset).
3187 See ccl/bib1 for an example.
3189 Fixes in ASN.1 compiler for C++ compatibility.
3191 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3192 and "op_or" to avoid conflict with C++.
3194 Fixed problem with GNU readline detection on Redhat 7.0.
3196 Added step-size for Scan backend handler.
3198 Fixed bug that made the frontend server crash when no attribute
3199 set was specified for scan.
3201 Front-end server automatically switches to original working directory
3202 when installed as an NT service. Previously -w had to be specified to
3205 Added extended attributes for retrieval module (data1), so that data1
3206 records carry d1_readXML/SGML attributes. d1_read also supports
3207 null-data rules ( <tag/>)
3209 On UNIX when POSIX threads are available, a separate library libyazthread
3210 is created. Programmers should link with that library and the yaz library
3211 when using threads. The reason for the split was that some applications
3212 on Linux, such as Apache, doesn't work well when using shared objects that
3215 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3216 (or any frontend server) in SSL mode by specifying ssl: followed by
3217 address. Only tested on UNIX.
3219 Added feature for CCL module. Virtual structure s=al or s=ol generates
3220 and-list and or-list respectively instead of phrase search.
3224 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3225 log_mask_str. This was done to avoid name conflicts with other libraries
3226 (such as other PHP extensions).
3228 Added raw OID member for preferred record syntax (request_format_raw)
3229 and returned record syntax (output_format_raw) for backend fetch method.
3231 Config file yaz-config now accepts options so that it returns specific
3232 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3234 Shared library support for UNIX using GNU libtool.
3236 * Modified backend interface. Request/Response struct's replaced by
3237 one read/write C struct. For example bend_fetchrequest and
3238 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3239 Every handler - even search has to be registered in bend_init
3240 handler. This means that the YAZ library no longer refers to
3241 external functions and it makes it possible to make the whole
3242 thing a single DLL/SO.
3244 Added Segment handler for backend server.
3246 Added Zmbol/Zebra administrative functions to YAZ client.
3248 Threaded frontend server on UNIX (when POSIX Threads are available).
3249 Starting the server with option -T enables multi-threading.
3253 Added configure option --enable-comp/disable-comp to control use
3254 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3255 located in sub directory asn.
3257 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3258 in ${exec_prefix}/bin along with the other programs yaz-client and
3261 GNU automake used to maintain makefiles.
3263 Added several OID's.
3265 Changed retrieval module so that we can load records with no abstract
3266 syntax defined. Tagpaths in these records are fully composed of string
3269 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3273 On UNIX, the generated makefile now supports a proper 'make install'.
3274 The prefix can be set via GNU configure to set the install location
3275 (default is /usr/local).
3277 * YAZ programs client and ztest were renamed to yaz-client and
3278 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3279 locations, such as /usr/bin,/usr/local/bin,etc.
3281 * YAZ Header files were moved from include to include/yaz. YAZ Header
3282 files are referred to as include <yaz/log.h> rather than <log.h>.
3283 The YAZ include path (-I ..) is therefore the same as before. Programmers
3284 should update their #include statements or use -Ipath/include/yaz
3285 instead. The main motivation for doing this change is that YAZ header files
3286 can be installed in "standard" locations /usr/include,/usr/local/include
3287 without introducing conflicts, since ALL YAZ header files are stored
3288 in subdirectory yaz (under /usr/include for example).
3290 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3291 rather than project/workspace files. We switched because project files
3292 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3295 Changed name of logging function, logf, to yaz_log, to prevent name
3296 clash with some math-log functions. The YAZ header log.h defines logf
3297 to yaz_log (#define) so there should be no incompatibilities by this
3300 Added bend_start/bend_stop handlers for server. These handler are
3301 called on start/stop of server. For windows they are called whenever
3302 a service is started/stopped.
3304 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3305 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3306 in util/yc.tcl. The auto-generated C code structures are, in a few
3307 cases, incompatible with the old decoders. There are differences in the
3308 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3309 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3310 The preprocessor variable ASN_COMPILED is defined when the compiled
3311 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3312 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3313 wish to use the old encoders/decoders you can specify --disable-yc
3316 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3317 version so that it supports both new - and old version of DB Update
3319 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3320 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3321 change. The name parameter can be set to 0 in which no name is specified
3322 for the construction. The macros odr_implicit and odr_explicit sets name
3323 parameter to zero for the construction involved. New macros
3324 odr_implicit_tag and odr_explicit_tag are similar to the others,
3325 except that a name parameter is added. For programmers' that don't use
3326 ODR they probably only need to change the call to z_APDU and z_External.
3328 Added access control facility by interfacing the TCP wrapper library.
3329 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3330 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3331 name of the daemon and enables the access control as specified in
3332 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3334 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3335 den Dool <H.M.vdnDool@kub.nl>.
3337 Added reference ID parameter to most functions in server API - refer
3338 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3340 Changed name of ccl library to libccl.a (was ccl.a).
3342 Fixed bug in decoder for Explain (Category TargetInfo).
3344 Added support for GNU readline in client. Thanks to Jacob Poulsen
3345 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3347 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3348 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3349 IMPLEMENTATION! This change was made to the development version before
3350 the ZIG decided to retract the amendment. If any users MUST be
3351 compatible with the original Update definition, PLEASE CONTACT US, and
3352 we will include a separate definition corresponding to the old Update
3353 ES. Note that because of the change to the ASN.1 of the
3354 TaskPackageRecordStructure we cannot define a single structure that
3355 will support both versions.
3357 * Added const modifier to buffer parameter for some ODR/BER encoding
3358 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3359 completeWAIS, odr_dumpBER.
3361 Fixed bug in client.c which caused a crash when a scanResponse didn't
3362 contain positionOfTerm.
3364 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3365 * will cause an error in a client if a non-YAZ target sends both a
3366 * list of Scan entries and non-surrogate diagnostics.
3368 Retrieval module enhancements. Tag sets may be typed in the reference
3369 to it. From the .abs-file the "tagset" directive takes a third optional
3370 integer type for the tag set referenced. From a .tag-file the "include"
3371 directive takes a third optional type as well. The old "type" directive
3372 in the tag set itself is still recognized but acts as the default type
3375 Backend interface change. Individual Scan terms returned from bend_scan
3376 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3377 in include/backend.h.
3379 Retrieval module enhancements. Multiple tag sets and attribute sets may
3380 be specified in abstract syntax specs. Revised the error/warning for
3381 logging messages reported by the retrieval module when reading the
3384 Object Identifier system (oid_..) changed. The API is backwards
3385 compatible but the oid-routines now allocates new OID's when needed.
3386 Raw OID's may be specified in oid_getvalbyname.
3388 YAZ now uses GNU configure to generate Makefile(s).
3390 * Minor changes in some of the member names of DeleteResultSetRequest and
3391 DeleteResultSetResponse. See include/proto.h.
3393 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3394 and added member 'languages' in TargetInfo (which was missing).
3396 Changed the way attribute sets are handled in the retrieval
3397 module. These are now cached, just like the abstract syntaxes
3400 Changed YAZ so that it links with compiled ASN.1.
3402 Added Explain-schema definitions and mapping routines. The following
3403 Explain categories have been implemented: AttributeDetails,
3404 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3406 Fixed minor bug in Windows version of Server Library.
3408 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3410 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3412 Added EXTERNAL: UNIverse Resource Report (non-standard).
3414 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3415 ENUMERATED and SET OF.
3417 * Added 'const' to some of the char pointer arguments for the
3418 functions, data1_read_node, data1_getelementbytagname,
3419 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3422 Fixed bug in data1_insert_taggeddata - the last_child member of
3423 parent wasn't initialised.
3425 * Changed data1_read_record and data1_read_node so that the supplied
3426 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3427 doesn't refer to any parts of the "SGML"-buffer.
3429 Fixed bug in server library (Windows version of statserv_remove).
3431 * Changed code so that it compiles as C++. The type definition
3432 of Odr_fun which is a member of Odr_arm was changed. The result is,
3433 that an explicit typecast is needed for the fun pointer when
3434 using Odr_arm - as in:
3435 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3437 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3439 Implemented the new structured date and time definition as approved
3440 by the ZIG. Added schemaId element to the specificTag in Espec-1
3441 (also approved at the last ZIG). Thanks to RVDM.
3443 Added some Object identifiers (RVDM).
3445 Changed the Update Extended Service (RVDM).
3447 Added command "refid" to client which specifies referenceId for
3448 the following requests.
3450 Implemented extended service handling for server. See ztest.c
3451 for an example as well as backend.h. New handlers are registerd
3452 in the Init handler.
3454 * Changed interface for sort in server.
3456 Added new members to statserv_options_block. It allows a server
3457 to read options from another source than just the command line. Thanks
3458 to Charles Woodfield.
3460 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3461 renamed to zboolean. Some C++ compilers complained about the name.
3463 Minor changes to gils.abs. Added index 's' (sort) on title
3464 and date/time-last-modified.
3466 --- 1.4pl2 1998/1/30
3468 Fixed bug in server library regarding inetd mode (-i). This bug
3469 was introduced by release 1.4.
3471 --- 1.4pl1 1998/1/29
3473 Added sort facility in client and backend server interface.
3475 Fixed problem with dependencies in Makefile(s).
3477 Fixed bugs for encoders/decoders of extended services and
3480 Implemented sub-tree feature for schemas. Sub-trees are
3481 referenced in *.abs-files. See explain.abs for an example
3482 of the use of this feature.
3484 Modified bib1.att; local attributes for ANY didn't include
3485 ANY itself (only affects use of the retrieval module).
3487 Fixed bug in plain SGML reader in function data1_read_node:
3488 tags with prefix "var" was incorrectly interpreted as variants.
3490 Added feature "sub-schemas" to enable references to - and definitions
3491 of - group of elements.
3493 * Removed member parent from type data1_element (in data1.h).
3495 Implemented function odr_nullval() that returns the value of
3498 * Removed member num_children from data1_node (in data1.h).
3500 Made NT service interface part of the server library. The
3501 function statserv_main uses the NT service when required and
3502 calls the statserv_start / statserv_close routines.
3504 Routine zget_SearchRequest and zget_PresentRequest fills
3505 resultSetName/Id member with "default" instead of "Default".
3507 Fixed memory leak in server. Request queue member wasn't freed.
3509 Fixed nmem_exit so that memory is freed.
3513 Revised the CCL parser utility to be thread safe.
3515 Added function, oid_ent_to_oid, to replace the function
3516 oid_getoidbyent, which is not thread safe.
3518 * Added nmem_init and nmem_exit to initialize and release
3519 NMEM resources. Function nmem_init should be called once in the
3520 initial thread before NMEM/ODR is used. statserv.c and client.c
3521 have been changed accordingly. The change was necessary to make
3522 NMEM thread safe. The NMEM memory pool is shared amongst threads
3523 in a process. Unix-based applications will still work fine without
3526 Added NT Services interface for the the Z39.50 (statserv) Server.
3527 Refer to the ztest.c source on the usage.
3529 Windows 95/NT port using MSVC5.0. Project files are included in the
3532 * Defined new 'global' handle for the retrieval (data1) system. The
3533 new handled, data1_handle, describes the state of the data1 system.
3534 This handle is passed as first argument to virtually all
3535 data1 related routines. The functions data1_create and data1_destroy
3536 creates and destroys a data1 handle respectively.
3538 Added ODR encode stream member to all backend request structures
3539 init, search, scan etc. This stream should be used to allocate all
3540 memory used for the response when thread safe operation is needed.
3542 Changed the comstack utility, cs_addstr, to be thread safe. The
3543 returned hostname string returned by the function is now part the
3546 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3547 function. The cs_straddr takes a COMSTACK handle as argument, so this
3548 function must be used after cs_create and before bind/connect.
3549 This function is thread safe.
3551 Moved test server to 'ztest' directory - generic server code still
3552 in 'server' directory.
3554 Made prefix query (pquery.c) utility thread safe.
3556 Added new function modifier YAZ_EXPORT to 'export' public DLL
3557 functions when using windows (see include/yconfig.h).
3559 Added definitions to the OID database (util/oid.c) (RVDM).
3561 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3563 Added call to ccl_rpn_delete in client program.
3565 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3566 release of RPN structure.
3568 Added support for C++, headers uses extern "C" for public definitions.
3569 With input from RVDM.
3571 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3572 Thanks to Ronald van der Meer (RVDM).
3574 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3576 Added support for private extensions to the OID database
3577 (oid_setprivateoids()). Thanks to RVDM.
3579 Added optional, physical ANY (key replication)
3581 Fixed null-reference problem in GRS-1 output filter.
3583 Proximity operator added to Prefix Query Format (PQF).
3585 In test client command "base" accepts multiple databases.
3587 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3591 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3593 Smallish bug-fixes in the new encoders/decoders (explain).
3595 Bug fixed in DeleteRequest.
3597 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3599 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3601 Added SOIF syntax (using private OID for now) to retrieval module and client.
3603 Added Update extended service.
3605 Added SearchResult-1 additional info structure.
3607 Added optional CCL (ISO8777) interpreter as separate module. Available
3610 --- 1.2 1996/6/10 (1st anniversary release)
3612 Added Summary record syntax. Lightly tested.
3614 Added OPAC record syntax. Untested.
3616 Added ResourceReport service encoders/decoders. Untested.
3618 Fixed bug in z_Unit - wrong tagging on unitSystem.
3620 Fixed bug in the DiagRecs decoder.
3622 Added options for max PDU size and session timeout to frontend-server.
3624 Added documentation of query-language parsers and other supporting utilities.
3626 [frontend-server] Added Attribute set to the bend_scanrequest API.
3628 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3629 surrogate diagnostics were generated.
3631 [retrieval] Allow multiple local values for attribute.
3633 [retrieval] Allow multiple attributes per element in .abs files. index type.
3635 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3637 --- 1.1pl2 1996/4/10
3639 Minor changes, mostly specific to Zebra's requirements (retrieval)
3643 Repaired bug in frontend server when running multiple listening
3644 endpoints in dynamic mode.
3646 z_External() now won't break if a known, ASN.1 value comes encapsulated
3647 in an octet-string. The value will pass through unmodified in an Odr_oct.
3649 Added a bit of code to the demo client to decode & display
3650 ASN.1-structured records represented in the octet-aligned branch of
3651 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3653 Added z_ext_getentbyref() to the ASN module. Doc updated.
3655 * Completed the SCAN definition in the ASN module. This may break SCAN
3656 code based on older YAZ-versions at compile-time. The fix is easy -
3659 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3660 under the SCAN definition. Remember to initialize this, server-people.
3662 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3663 that this does not extend to ODR and ASN.
3665 Comstack allows insertion of established socket (primarily for
3666 inetd-operation of servers). Doc updated.
3668 Front-end server can now start from the inetd in TCP mode. Doc
3671 --- 1.0pl4 1996/1/24
3675 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3676 the rank and record number.
3678 Adjustments to the frontend server.
3680 Fixed diagnostic BER dumper. It ignored the file argument.
3684 Various changes to retrieval module.
3686 Changed the union discriminators of the protocol files from enums to
3687 ints paired with #defines.
3689 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3692 *Changed operator in the RPN structure to 'roperator', again to avoid a
3695 Fixed problems in Explain decoders/encoders.
3697 --- 1.0pl2 1995/12/6
3699 Memory bug in log module fixed.
3701 --- 1.0pl1 1995/12/5
3703 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3705 Bug in Explain DatabaseInfo module fixed.
3707 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3711 The shift to v1.0 signals that we now consider the *core* functionality
3712 of YAZ reasonably stable (the core being more or less equivalent to
3713 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3714 tested (Explain not at all - though that will happen soonish).
3716 Minor changes to code to support Windows port.
3718 Various minor changes after we're getting to use GRS-1 & co. more.
3720 Added Espec-1 format.
3722 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3723 of the protocol and it cannot be selected when encoding (maps into 'string'
3724 when decoding). Needed to talk to some servers.
3726 Demo client can request simple element set names.
3728 Added Diagnostic Format encoders/decoders.
3730 Added simple Close handling to frontend server (no hooks for resource
3731 reporting yet), and demonstration client.
3733 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3735 --- 1.0b3 1995/08/24
3737 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3738 handled incorrectly when records were requested in the searchResponse. This
3739 will only affect you if you use the frontend-server.
3741 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3742 Test-client will ask for and print GRS1. Ztest will return dummy records
3745 Added Explain encoders/decoders to the service-level API. Untested.
3747 Added Extended Services: Item Order encoders and decoders to the Service-
3748 level API. Untested. We could use a recent copy of the pertinent bits
3749 of the ILL protocol to add those bits.
3751 Added diagnostic format 1 encoders/decoders to the service-level API.
3754 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3755 odr_cons.c, which causes a more correct output.
3757 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3758 was always set to 0 when no records were requested in the searchRequest.
3760 * Added better external-handling. This shouldn't harm old code that
3761 *encodes* externals. It can break code that looks for a
3762 'single-ASN1-type' representation, since those types that are known
3763 are now decoded immediately. Look at the SUTRS sample code in
3764 seshigh.c and client.c. Documentation updated.
3766 Handling of structured records in bend_fetchresponse. Length -1 marks
3767 structured record, type is deduced from format field.
3769 --- 1.0b2 1995/06/27
3770 Fairly quick maintenance release to add SUTRS support.
3772 Fixed handling of SUTRS records in the demonstration client.
3774 * Added format field to the bend_fetchrequest and bend_fetchresponce
3775 structures of the backend API (frontend server). When the record is
3776 returned, the value of the format field is mapped to an OID. The
3777 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3778 of the record. The special value VAL_NONE in the bend_request means
3779 that no specific format was requested by the client. Documentation
3780 updated accordingly. Test server (ztest) will return a fixed dummy
3781 SUTRS record if your client requests SUTRS.
3783 Documentation updated accordingly.
3785 You can now set external libraries and RANLIB support in the top-level
3789 First public release.
