1 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
2 schema was given for search. YAZ-675
4 Add Solr date range searches. YAZ-621
8 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
10 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
12 ISO2709/MARC parse most octet aligned records; not just those that
13 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
14 MARC parse more records instead of just dumping as is. YAZ-670
16 ZOOM: proper caching for variations of record schema. YAZ-671
18 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
26 New utility z_get_HTTP_Response_details - an extended version of
29 New utility yaz_url_get_error which returns error message of last
30 failed yaz_url_exec call.
32 yaz-url and url functions: allow max HTTP redirects to be controlled.
34 New functions yaz_file_glob2, yaz_xml_include_glob.
35 These functions takes a flags parameter, which, for now only controls
36 whether to fail inclusion of a non-existing file (without glob
37 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
41 For MARC XML parsing, allow record without leader. A fake/default leader
42 is inserted and a warning is tagged with the record.
44 ICU: fix leak in in icu_iter_get_org_info.
48 ICU: fix bug in icu_iter_get_org_info (un-init variable).
52 Implement z_HTTP_header_remove.
56 ICU: Disallow 0 ptrs for some ICU string utilities.
58 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
59 returns original tokens (before normalization).
61 CCL: avoid z39.58/regex truncation when not needed. Apply only the
62 conversion of those masks, when absolutely necessary.
64 CCL: configurable masking character - @mask. Default masking character
67 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
68 full response anyway, so a Transfer-Encoding header will obstruct the
73 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
74 picking a socket. Problem is that some systems has IPV6 support, but
75 we can't create sockets for them, so we pick AF_UNSPEC first.
77 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
78 use content_len to determine resulting Content-Length in HTTP response
79 and NOT Content-Length supplied in headers by user.
81 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
82 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
84 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
87 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
88 with big endian and unsigned char (by default).
92 Fix yaz-client connect (crash in 4.2.55).
96 Fix proxy/host problem for ZOOM that could occur if unix sockets
99 New Debian package libyaz4-dbg.
101 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
102 differently in tcpip_close.
104 --- 4.2.54 2013/04/17
106 Windows installer of YAZ includes YAZ4J as a component.
108 CQL: allow "extra terms" again, by default. Thus, the CQL parser
109 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
110 and earlier. CQL parser may operate in strict mode where queries
111 not conforming to the standard BNF are rejected (syntax error).
112 Whether the CQL parser operates in strict mode is controlled with
113 cql_parser_strict . Strict mode enabled with option -S for utilities
114 cql2pqf and cql2xcql .
116 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
118 --- 4.2.53 2013/04/10
120 New charset, MARC-8c, which is like MARC-8 but allows control characters
121 0x01 through 0x1F, except ESC to be passed through verbatim.
123 Fix a problem with duplicate sub field character in MARC output. Problem
124 happened only when output was MARC-8 encoded.
126 --- 4.2.52 2013/04/03
128 yaz-ztest: Use hash for fake hit count. Before, random number was used.
129 This is problematic for unit tests using yaz-ztest. This patch also makes
130 a hash for CQL queries. For RPN, any term with a leading digit will be
131 treated as pseudu hit count (to force any particular hit count by a client).
133 yaz-ztest: return unique MARC dummy records. Beyond record offset
134 24, the author surname is patched with offset to make all records
137 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
138 on system wide default (/proc/sys/net/ipv6/bindv6only).
139 @4 binds to IPV4 only. @6 binds to IPV6 only.
141 Update CQL API documentation a bit
143 CQL: don't accept extra terms for queries. Makes the CQL parser
144 stricly conformant to the standard.
146 --- 4.2.51 2013/02/12
148 GFS: scan handler gets extra_args from request and may return extra
149 response data . That's for SRU only.
151 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
153 --- 4.2.50 2013/01/30
155 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
157 OPACXML: sync spelling of availabilityDate in XML to that of Schema
158 opaxxml.xsd. The schema had the correct spelling of this member always.
159 The ASN.1 was mis-spelled and still is (API change) - we are
160 not changing this. However, the OPAC to XML conversion had yet
163 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
166 New function, z_ext_record_oid_nmem, which is similar to
167 z_ext_record_oid but takes NMEM rather than ODR
169 --- 4.2.49 2013/01/18
171 ICU: New conversion element 'join' which joins tokens into one
172 with a custom character given by rule attribute.
174 --- 4.2.48 2013/01/10
176 New GFS search member: present_number. This is a hint to the
177 search handler how many records are going to be fetched immediately
178 following search. There's no guarantee that it's going to be the case,
179 since it depends on hit count (for Z39.50 piggyback) and whether errors
182 Make a few functions static (private). The functions getbyte_stream,
183 ungetbyte_stream and yaz_gets are now private. They were never declared
186 yaz-marcdump: exit(5) for serious decoding errors
188 ISO2709 decoding: be more picky WRT header
190 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
191 was only used as to indicate that next-result-set-position should be
193 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
194 Based on patch from Ashley Sanders.
196 Make some functions static/private in PQF parsing. Those functions were
197 never declared in a public header and so should not be in use by
198 applications based on YAZ.
200 --- 4.2.47 2012/11/23
202 ZOOM: special options to control APDU logging.
203 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
204 logging of APDUs until "saveAPDU" option is set again. If logging is
205 already enabled the effect is that current APDU buffer is cleared.
206 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
207 logging (default behavior on new connection).
208 The APDUs sent/received can be obtained by using
209 Using ZOOM_connection_option_get(c, "APDU") or
210 ZOOM_connection_option_getl(c, "APDU", &l).
212 GFS: relay implementation_version from backend
213 From 3.0.40 and later, implementation_version from backend was
214 not used in init response at all.
216 --- 4.2.46 2012/11/15
218 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
219 mode at all. Probably never did.
221 Make a new version of ztest.pem that, at least, is not expired.
223 --- 4.2.45 2012/11/13
225 Fix description of CCL directive 'case'.
227 More tight checking of form arguments (yaz_uri_to_array). Makes
228 YAZ better at rejecting big and/or bad POSTs.
230 SRU decoding does not report more than up to 10 invalid arguments.
232 rpn2cql: less quotes in generated terms. Semantics unchanged, but
233 it's prettier this way.
235 --- 4.2.44 2012/10/25
237 New utility yaz_decode_init_diag. Defined in proto.h.
239 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
240 given for unix local socket.
241 The COMSTACK string for doing so is:
244 unix:/myfile:tcp:localhost:9999/mybase
245 unix:/myfile:localhost:9999/mybase
246 unix:/myfile:http://fakehost/mybase
248 debian: Use dpkg-buildflags in build process.
250 --- 4.2.43 2012/10/19
252 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
253 global's SRU service uses a recordPosition scheme starting from zero.
254 First record's position should be one
255 according to the standard.
257 --- 4.2.42 2012/10/18
259 Allow more namespaces for SRU. This is to allow, for example, an
260 incorrect namespace returned from server
261 http://services.igi-global.com/sru .
263 Minor fixes for compilation on Windows.
265 --- 4.2.41 2012/10/11
267 daemon: log total number of bad signals from child on stop so that it
268 is more easy to spot problems with child worker processes.
270 retrieval: empty backend name attribute omits element set
271 from being used in retrieval.
273 --- 4.2.40 2012/10/04
275 Implement Solr sort strategy "solr", similar to sru11 sorting.
276 This will implement the correct parameters on Solr requst to do
279 --- 4.2.39 2012/09/28
281 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
284 MARC: Extra/missing indicator handled for MARCXML.
285 The indicator length is given in header and is the same for the
286 whole record. If attributes ind1, ind2 are missing, then content
287 character defaults to blank. Extra indicator attributes (beyond)
288 indicator length are treated as an error.
290 Reformat: delete trailing whitespace
292 --- 4.2.38 2012/09/17
294 MARC: fix non-ASCII characters for leader. This is to ensure we can
295 generate XML in UTF-8.
297 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
298 in one node with structure word.
300 --- 4.2.37 2012/09/04
302 yaz-json-parse: JSON output may be pretty printed by using option
305 Increase default value of max message for Z39.50 Init for GFS, ZOOM
306 and yaz-client. Old value was 1 MB. New value is 64 MB.
308 --- 4.2.36 2012/08/22
310 yaz-client: don't display bogus records from SRU servers. Some SRU servers
311 return more records than given by *maximumRecords*. Skipping those in
314 record_render: simplify buffer return handling and fix at least one bad
315 memory reference, that broke the test_embed_record sometimes.
317 Allow http://user:pass@host notation for yaz_url_exec.
319 zoomsh: allow shell command to be executed. Via the system(3) call.
321 yaz_poll: Allow num_fds == 0
323 yaz-client: fix bad encoding of "itemorder item". The itemorder
324 item <no> - command forgot to use length of encoded Item Request
325 package. Error present since YAZ 3.
327 yaz-ztest: fix bad usage of session handle. Bug was introduced when
328 result sets were saved (271a9c83).
330 SRU recordPacking: guess record packing in response rather than looking
331 at the recordPacking element which, OF COURSE, changed semantics in SRU
334 Decode SRU 2.0 responses. The official namespace for responses, according
335 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
336 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
337 nature.com's server, however, usee namespace
338 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
339 we are now using a glob-expr to match up the namespace. ZOOM C and
340 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
341 I can not find a single real example showing the "real" namespace in
342 the documentation from OASIS. The namespace for requests is different
343 from responses, but this is not added to YAZ yet, when we don't encode
346 --- 4.2.35 2012/06/26
348 zoom/record_render: add support for Base64 decoding fo MARC records
349 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
350 which will decode base64 + ISO2709 marc-8 encoded material from text node
353 --- 4.2.34 2012/06/07
355 Add missing definitions ZOOM_resultset_get_facet_field_by_index
356 and ZOOM_resultset_facets_names.
358 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
361 Change APDU dump printing to avoid long leading blanks. For levels 16
362 or larger the level is shown and the indentation is truncated but
363 recursed with modula 8. This makes it still reasonable easy to read
364 - even for nested BER dumps.
366 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
367 return 0 (incomplete package) in case where the BER package was
368 considered too nested (return value of -2).
370 dumpber: lines of level 15 are not indented further. Two spaces per
371 indentation; indentation 15 or more is indented to a fixed indentation
372 and augmented with a level=<no> indication.
374 zoomsh: increase max size of command+args
376 GFS: No limit in RPN buf size in CQL to RPN conversion.
378 --- 4.2.33 2012/05/09
380 New function for daemon utility, yaz_daemon_stop .
382 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
384 --- 4.2.32 2012/04/25
386 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
387 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
389 --- 4.2.31 2012/04/23
391 YAZ daemon utility relays SIGUSR1 to child process.
393 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
394 would result in en empty database list - which in turn would result in
395 encoding failure for search.
397 Fix reading beyond string in yaz_sort_spec.
399 --- 4.2.30 2012/04/11
401 Add two new SRU diagnostics:
402 236: Access to specified database denied
403 1015: Init/AC: Maximum number of simultaneous sessions for Userid
405 Document the very useful ZOOM-C option "apdulog".
407 CQL to RPN: term may be passed through verbatim. This is enabled with
408 truncation.cql . The assumption being that the term is already CQL.
410 --- 4.2.29 2012/03/20
412 record_conv: leader spec may be given for marc element.
413 The leader spec is given as attribute leaderspec for element marc.
414 For example to convert a MARC21 record from MARC-8 to UTF-8:
415 <marc inputformat="marc" outputformat="marc"
416 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
418 record_conv: allow user-XSLT params. For example:
419 <xslt stylesheet="MARC21slim2DC.xsl">
420 <param name="myparameter" value="myvalue"/>
421 <param name="otherparameter" value="othervalue"/>
424 record_conv: fix error handling for missing marc charsets.
426 CQL: fix extra terms in wrong order.
428 --- 4.2.28 2012/03/06
430 record_conv: modify new API for conversion types. The conversion types
431 may be passed in new functions yaz_record_conv_configure_t and
432 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
434 Avoid mixed statement/variable declare; fixes compilation with Visual
437 --- 4.2.27 2012/02/28
439 Add non-standard SRU diagnostic: 235: "Database does not exist".
440 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
441 Update SRU to Bib-1 diagnostic maps accordingly.
443 CCL: add two new diagnostics for unsupported masking. The new
444 diagnostics are: "Embedded truncation not supported" and
445 "Single charcacter mask not supported".
447 --- 4.2.26 2012/02/23
449 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
451 --- 4.2.25 2012/01/11
453 Build YAZ for Ubuntu Oneiric.
455 CCL: allow parantheses for proximity operands. For example CCL query
456 (a) % (b) is now allowed.
458 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
459 marked dead, rather then being destroyed. If not, the session memory is
460 being free'd before the search/scan handler is finished. Also destroy
461 'request' memory in request_release rather than in various places,
462 which resulted in leaks from time to time.
464 --- 4.2.24 2011/12/21
466 cql_sortby_to_sortkeys: honor sort prefix.
468 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
469 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
470 The rpn2cql family of functions now always returns quoted CQL terms.
472 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
474 --- 4.2.23 2011/12/15
476 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
477 sequence is treated as one. For example, &&a=b&&&c& is identical to
480 --- 4.2.22 2011/12/05
482 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
483 APDUs for a connection to a WRBUF.
485 --- 4.2.21 2011/11/23
487 Fix cql_sortby_to_sortkeys. Completely broken before.
489 Make CCL's @truncation work again.
491 --- 4.2.20 2011/11/09
493 New ZOOM connection setting: tproxy. It's like proxy, but does not
494 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
495 to set resolved address + port for a connection outside ZOOM itself.
497 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
499 --- 4.2.19 2011/11/07
501 Fix uninitialized variable in Solr spell support (could cause SEGV
502 for SRU response decoding).
504 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
505 back-end's addinfo through into the ZOOM response addinfo.
507 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
508 they are separated by a colon and a space rather than simply
511 --- 4.2.18 2011/10/28
513 Add support for Solr spell-checking/suggestions through ZOOM.
514 If a Solr target has been configured correctly for spelling-checking
515 and suggestions, these will now be returned on the ResultSet option
516 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
518 --- 4.2.17 2011/09/28
520 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
521 with a flag whether to substitute escape sequences or not.
523 --- 4.2.16 2011/09/22
525 Fix nmem_strsplit_escape to substitute escape char properly.
527 New option for zoomsh -e , which makes it abort on first error and
528 return process exit code to indicate success/failure.
530 YAZ options utility supports special option -- which makes all it treat
531 all following arguments as non-options.
533 --- 4.2.15 2011/09/16
535 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
536 searched if absolute filename is given.
538 Fix conv_xslt() error-reporting when stylesheet is not found.
539 (The value of fullpath is meaningless in this situation.)
541 --- 4.2.14 2011/09/07
543 Fix problem in CQL sort node creation: un-initialized memory.
545 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
546 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
547 CQL sortby depending on whether Type-1 or CQL is actually sent to the
550 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
551 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
553 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
554 will make it possible to use both single-character mask (#) and wildcard (?)
555 in CCL . Throw diagnostic for left truncation because that is not supported
558 --- 4.2.13 2011/09/01
560 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
561 cases using escapes (\-sequences) and masking.
563 PQF parse fix: A trailing backslash followed by end-of-string (\0)
564 would result in a read one byte beyond string.
566 rpn2ccl may use Z39.50 masking for terms (t=z).
568 ICU check fix. Don't include library -lCrun on Solaris, unless present.
570 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
571 not --cppflags (which seeems like an error in icu-config).
573 --- 4.2.12 2011/08/27 RPM package only
575 cql2ccl: fix conversion of terms: operator characters were not
578 --- 4.2.11 2011/08/25 RPM package only
580 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
581 CCL parser will map both # and ? to their regular expression
582 quivalents (. and .*).
584 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
585 of reserved CQL characters.
587 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
588 is, so that they are passed through.
590 --- 4.2.10 2011/08/24
592 ZOOM SRU mode: more aggressive re-connect.
594 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
595 made available as a utility function, declared in <yaz/logrpn.h>
597 rpn2cql_structure() supports proximity nodes (except that the Type-1
598 proximity node's "exclusion" binary is ignored, as there is no way to
599 express that in CQL). Fixes bug #4564.
603 Fix SEGV that could occur if set command of zoomsh was given without
604 value (2nd argument).
606 Fix SEGV that could occur if unsupported transport was given for
607 COMSTACK - say https (when SSL was unavailable).
609 Build yaz-url on Windows too.
613 New utility to get web content. Header is url.h. A command line tool
614 yaz-url is part of the distribution and packages.
616 Fixes for SSL COMSTACK (when gnutls is in use).
618 New functions yaz_base64{encode,decode}. Header is base64.h.
622 ZOOM C includes HTTP response buffer as additional info if it fails
623 to decode the SRU response.
625 Make wrbuf_json_puts available.
629 zoom: throw diagnostic for invalid value for option "sru". Before a
630 bad SRU request was sent.
632 Adding new utility wrbuf_vp_puts.
634 Add cclxmlconfig.obj to win/makefile. It was missing completely.
638 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
639 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
640 redirect was used at the same time.
642 MARC line mode decoding: be less picky about length given - first
643 5 digits of header that is.
645 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
647 Changes to decoding of SRU records: a record with recordPacking=xml is
648 modified with a new root element <yaz_record> if the recordData contains
649 multiple children elements. This is to make the record XML parseable
652 RPN to Solr conversion: encode special characters.
654 Generic Frontend Server: fix uinitialized member, stepSize.
658 Fix a bug in SRU decoding of records.. The database records stored
659 had un-initialized memory, but it would only be seen with yaz_record_render
660 and type_spec="ext" .
662 Fix a bug in ccl_qual_dup introduced in 4.2.3.
666 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
670 Add new utilities to convert from CQL to CCL . These utilities have
671 prefix cql_to_ccl defined in cql.h.
673 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
674 lead to memory heap corruptions when ICU utilities were in use.
678 Make compilation work without Libxml2.
680 yaz-client: remove redundant blanks in display of searchResult-1 term
685 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
686 resulting CQL node (tree) in a new node CQL_NODE_SORT.
688 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
689 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
690 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
691 Note that the CQL sortby spec is only converted when the GFS is already
692 converting from CQL to RPN (cql2rpn element).
694 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
695 specify whether to collapse delimitors or not. The existing nmem_strsplit
696 do collapse (collapse parameter = 1).
698 Windows installer: For NSIS, set InstallDir depending on x86/x64.
700 Rename internal func yaz_use_attribute_create. While non-static, this
701 function is not declared in a public header.
705 Add -lCrun when linking with ICU on Solaris.
707 More quicks character set conversions for OPAC records.
711 fix problem with record_render: records were converted (character set
712 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
716 SRU: add methods for handling DADS SRU-proxy facets.
718 Separate OPAC record character set for ZOOM_record. yaz_record_render
719 allows a character set given as charset=from/opacfrom,to where 'from' is
720 the character set of a bibliographic record, 'opacfrom' is character set
721 of OPAC record and 'to' is the target character set.
725 yaz-client: show may XML format records. Command show followed by 'format'
726 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
729 src/stemmer.c: Avoid using unnamed union. It is not supported by some
732 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
735 Update yaz.spec to operate on both SLES11 / Centos 5.5.
737 RPM: Release includes 'indexdata' name. Use indexdata in release name so
738 this package can be distinguished from other vendors.
740 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
741 as determined by configure
743 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
745 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
746 returns no error and no record, the present request is considered
747 partial (only a subset of the records could be returned by backend), and
748 so it is appropriate to set Present Status to partial-4.
752 Move yaz-config man pages to section 1.
754 More documentation about Solr.
756 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
757 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
758 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
759 peers on some Linux systems. However, in general that does not work
760 so YAZ can not rely on that to work. Debian changed behavior in this
761 respect from Debian lenny to Debian squeeze (still testing as of Oct
763 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
765 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
769 Fix yaz-config output: echo_source not set correctly by configure.
773 Solr Web Service support for yaz-client and ZOOM.
775 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
777 --- 4.0.12 2010/08/17
779 Z39.50 facet support. Facet specifications are passed for search in
780 other-information with ASN.1 as defined in facet.asn and OID
781 .10.1000.81.5 . Facets are expressed as an Attribute list as known
782 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
783 3 is limit (number of entries to get in response). yaz-ztest returns
784 dummy facets if a client asks for them.
786 --- 4.0.11 2010/07/09
788 CCL fixes: bug 2895 and bug 3539.
790 GR1-display: add comma in display - was removed by mistake in
793 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
795 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
797 --- 4.0.10 2010/06/18
799 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
800 result set from a connection. The result set will be on its own
801 thereafter; no operations on it will perform retrievals from a target.
802 Only cached copies are returned.
804 ZOOM C:fix case for HTTP servers responding with Connection:close.
805 Ensure that if there is a current task it is resumed (like fetching
806 more records in a result set) . Bug #3484.
808 PQF parser: use odr_atoi for Odr_int (not atoi)
810 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
811 values that contain any non-digits are treated as string attributes
812 (previously decoding only checked for leading character ([0-9]). PQF
813 encoding: attribute string values are not surrounded by double-quotes.
817 New utility for managing threads - thread_create.h.
819 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
820 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
821 but YAZ' implementation do.
823 Fixes for yaz_cond-functions on Windows 7.
825 DLL export more symbols.
827 zoomsh: show record do NOT render opac.
829 Remove *.la files from Debian and RPM packages.
833 Debian package libyaz-dev depends on libgnutls-dev again (was
834 removed in YAZ 4.0.6, but due to Libtool it is still needed
835 even though yaz-config do not list libgnutls libs).
837 ZOOM: Use only one WRBUF for returning string results for
838 ZOOM_resultset. Reduces memory usage for ZOOM in general.
840 ZOOM: ZOOM_connection do not use a shared pointer to
841 ZOOM_resultset after ZOOM_resultset is destructed by
842 user. Reverts to YAZ 4.0.4 behavior.
846 record-conv: fix problem with at least one XSL conversion -
847 due to probably incorrect usage of XML XSL documents.
851 Fix yaz-config for static mode and the use of SSL (gnutls).
855 Forward decl timeval struct in mutex.h and gettimeofday.h.
857 yaz-config: fix 'static' mode linking.
861 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
862 are wrappers for pthreads or Windows. For Windows these are put in
863 a separate DLL: yaz_cond4.
865 libyaz.la (whole source) is compiled with thread. If thread support
866 is enabled enabled, all source of YAZ is compiled with treading support.
867 This allows core utilities such as yaz_log to use thread facilities.
868 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
869 thread utilities. This commit moves mutex utilities (mutex.c) from
870 libyaz_server.la to libyaz.la.
872 yaz-json-parse displays leading text until error.
876 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
877 patch from Giannis Kosmas.
879 SRU: no longer URL encode SRU database. The URL for an SRU server is
880 a URL and such is alreeady encoded - at least when given with leading
881 http:// or https://. This reverts behavior to YAZ 3.0.50.
883 Support for new MARC XML notation TurboMARC which like MARCXML is a
884 complete representation of MARC/ISO2709.. This one, however, is more
885 compact and allows for faster processing with XSLT. TurboMARC can be
886 used in the marcdisp.h API, from the yaz-marcdump utility and from
889 yaz-ztest can be configured - via the database - to perform certain
890 delays when it performs operations search, present and single record
891 fetch. This allows testers to make yaz-ztest act as a real or even slow
892 Z39.50 server. Refer to the yaz-ztest man pages for details.
896 wrbuf_destroy allows NULL WRBUF passed to it.
898 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
900 Add ZOOM_connection_close.
902 No fixed size buffers for ZOOM shell - bug #3257.
904 tstodr: make it work on s390 platform.
906 New icu iterator-functions. The new icu_iter-functions makes it possible
907 to use ICU chains from many threads.
909 yaz-client: better syntax check for show command.
913 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
916 New simple local-file XML include facility which allows file glob-patterns.
917 Refer to yaz/xml_include.h.
919 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
922 ZOOM_record_get supports new parameter "format" which makes it format XML
925 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
926 JSONText in ECMA-262) is JSONValue, not JSONObject.
930 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
931 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
933 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
934 POSIX/Unix builds .so with major version 4.
936 Remove old LOG_-defines from log.h. They have been obsolete and
937 undefined by default for the last 5 years.
939 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
941 GFS: Remove socket (int *fd) from search_rr handler. The socket
942 descriptor ptr is a facility that allowed a search handler to supply
943 a socket which would serve as a callback - when search was complete.
944 This facility has now been in use for years.
946 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
947 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
948 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
949 returns 'const char *' rather than 'char *. The returned string is
950 read-only and should not be modified by applications. COMSTACK cs_close is
951 now a void function - it no longer returns int. No applications check for
952 the value and the implementations has always returned 0.
954 ZOOM: use size_t for scan hit counts and str size. Functions
955 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
956 occ (hit count) and len (string length) are now of type size_t pointer
957 rather than int pointer. This is to be able to represent large hit counts
958 and to also just to use the proper type for string length (strlen result).
960 New JSON parser. Refer to include/yaz/json.h .
962 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
963 Used to be int in some cases. Many wrbuf_-functions used to return an int
964 indicating some length.. These return values were never used. And so they
967 ODR: odr_malloc, odr_total now takes size_t for size.
969 clone_z_type: fix leak; occurred for encoding failures.
971 --- 3.0.52 2009/12/03
973 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
974 bug was introduced in 3.0.51.
976 --- 3.0.51 2009/12/02
978 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
980 tcpip comstack: fix leak for getaddrinfo.
982 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
983 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
984 Decoding of SRU "path" database is performed by private function
985 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
986 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
988 yaz-client: honor base command for SRU. Change when database setting
989 is applied for SRU and ensure it is kept when a connection is reset.
990 Change also the way errors are displayed or SRU (decoding of packages).
992 --- 3.0.50 2009/11/02
994 Add support for extra request / response data for SRU codecs and GFS.
995 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
996 for extra data response buffer and length. For the GFS, both request
997 and response data (XML) is carried in extra_args and extra_response_data
998 for the search handler. Patch by Ko van der Sloot.
1000 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1001 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1002 10010). This fixes bug #2113.
1004 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1005 cmdfile included a 'quit' command that would result in a memory violation.
1007 --- 3.0.49 2009/10/01
1009 Make a number of functions defined in xmlquery.c static. These have
1010 never been declared in a public header file (yaz/xmlquery.h) and was
1011 made public by mistake.
1013 Improve speed of character conversions (iconv utilities). This makes
1014 conversions from MARC-8 faster.
1016 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1017 unless type desired is "raw". This will prevent type "xml" from
1018 returning ISO2709 .. Which obviously can not be XML parsed.
1020 Fix memory leak in ZOOM that would occur if option apdulog was used
1021 on a re-used connection.
1023 Frontend server logs HTTP requests.
1025 Frontend server now sends Z39.50 close when it times out (sesssion has
1026 been idle for too long). Versions 2.0.30 and earlier also sent close.
1027 But due to a mistake this was disabled in all versions after that, i.e.
1028 the server would just close the socket immediately.
1030 yaz-client emits a better message when receiving an unrecognised
1031 userInformationField.
1033 Skip zero-length subfields when decoding ISO2709. This rare case happens
1034 if a record has two FS characters in a sequence. Without this patch
1035 there would be a reference beyond char array in using_code_len fragments
1038 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1040 --- 3.0.48 2009/08/28
1042 The show command offered by the zoomsh command now takes a 3d optional
1043 parameter type which is what is passed to ZOOM_record. If the type
1044 argument is omitted, "render" is used.
1046 RPN to CQL conv may use USE string attributes (bug #2978).
1048 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1050 --- 3.0.47 2009/07/08
1052 Function yaz_xml2query allows a diagnostic element in the PQF XML
1053 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1054 code and additional info respectively.
1056 The BER BOOLEAN is now the integral type Odr_bool which still happens
1057 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1058 typedef'd to Odr_int. This is still an integral 'int', but it may be
1059 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1060 ASN-1 compiler as well as programs has been updated to use the new types.
1062 --- 3.0.46 2009/06/08
1064 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1065 only the bibliographic record was rendered. For type=opac, an OPAC
1066 record is only returned if it is present.
1068 iconv: small fix for encoding of advancegreek.
1070 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1072 yaz-client: option auto_reconnect=on really reconnects.
1074 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1076 server: avoid null ptr ref for for yaz_poll errors.
1078 build: fix RPM build for RHEL 5.3.
1080 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1082 --- 3.0.45 2009/03/31
1084 Fixed bug #2709: TCP connect returns Invalid argument.
1086 Fixed compilation for mingw.
1088 Honor charset for raw records (ZOOM_record_get).
1090 Fixed use of errno for threaded mode that was seen on Solaris 10.
1092 Fixed argument passing with blanks in value for Windows Service.
1094 Disable YAZ' own log rotate by default (no 1 GB limit).
1095 The variable l_max_size which specifies the log file limit is set to 0
1096 (DISABLED): This is due to the fact that YAZ is most often deployed using
1097 logrotate. Also YAZ can not perform log rotate because of unsufficient
1098 permissions (setuid).
1100 --- 3.0.44 2009/02/17
1102 List supported encodings in man page for yaz-iconv.
1104 Fixed missing SSL libs for --libs output
1106 Re-established OID record syntax application-xml. Nobody should use it
1107 but we don't want to change soname because of this symbol being absent.
1109 --- 3.0.42 2009/02/02
1111 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1113 Added member named_result_sets for init handler struct for the GFS. This
1114 allows a server to disable named result sets.
1116 Removed OID record syntax application-xml.
1118 Added support for rule-based transliterator for ICU wrapper of YAZ.
1120 Fixed bug #1902: yaz-icu XML output.
1122 Make YAZ checks Emacs friendly.
1124 BITSTRING value shows value. Bug #2346.
1126 ISO2709 decoding: skip control characters from indicator data.
1128 Omit sort key by default in yaz-icu's output.
1130 Allow combined single char options (again) for YAZ' options function.
1132 Utility yaz-marcdump got option to display YAZ version (-V).
1134 Allow YAZ to use ICU 3.4.
1136 Added new ICU test case which illustrates removal of diacritics.
1138 --- 3.0.41 2008/12/29
1140 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1142 --- 3.0.40 2008/12/29
1144 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1147 Fixed bug #2352: yaz-marcdump crashes for certain record.
1149 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1151 Added support for Danmarc2 to UTF-8 conversion.
1153 Added support for ISO5426 to UTF-8 conversion.
1155 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1156 implementation version.
1158 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1160 --- 3.0.38 2008/11/10
1162 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1163 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1165 ZOOM C now interprets databaseName option for ZOOM connection as path
1168 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1170 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1172 Dummy Libxml2 types no longer defined in headers of YAZ'.
1174 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1177 --- 3.0.36 2008/09/26
1179 Various ODR chapter fixes.
1181 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1183 Added missing source for Windows compilation, mutex.c.
1185 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1187 For SRU connections in ZOOM all records up to "count" are now fetched.
1189 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1190 in Windows due to bad error handling for Libxml2.
1192 Added facility for sending arbitrary records (ASN.1 any) using
1193 ZOOM C's Extended service update. Patch by Sam Reynolds.
1195 New options for ZOOM C's connection, logapdu which makes ZOOM log
1198 --- 3.0.34 2008/06/18
1200 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1202 --- 3.0.32 2008/06/12
1204 Fixed memory violation that could occur when decoding UTF-8. This bug
1205 was only present in 3.0.30 of YAZ.
1207 --- 3.0.30 2008/06/06
1209 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1210 GNU TLS is used by default (if found).
1212 yaz-ztest returns OPAC records if a client asks for OPAC.
1214 Improved speed of MARC-8 encoding.
1216 Added support for lossy and loss-less MARC-8 encoding.
1218 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1220 Added new Windows Service wrapper (sc).
1222 yaz-client's itemorder command may now send a file.
1224 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1226 Added new function yaz_log_xml_errors.
1228 Allow (but warn) unknown XML attributes in MARCXML parsing.
1230 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1232 The UTF-8 to MARC-8 conversion now uses a different set of characters
1233 for Greek symbols. Bug #2120.
1235 --- 3.0.26 2008/02/21
1237 Added yaz_daemon (daemon.h).
1239 Fixed bug #2068: pkg-config trouble
1241 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1243 --- 3.0.24 2008/01/28
1245 Document --with-xml2 option.
1247 Added OPAC XML XSD (etc/opacxml.xsd).
1249 Allow glob mask for name attribute in retrieval element for the
1250 generic frontend server's retrieval facility.
1252 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1253 except POLLIN/POLLOUT.
1255 Fixed error handling in cs_listen. Bug #2037.
1257 --- 3.0.22 2008/01/20
1259 Fixed version in yaz/yaz-version.h.
1261 Fixed bug #2027: Crash when closing connection.
1263 Changed configure so that ICU support is only enabled if only ICU
1264 and Libxml2 is available (because the ICU chain is XML based).
1266 --- 3.0.20 2008/01/15
1268 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1269 is built. Only this DLL depends on the ICU runtime.
1271 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1272 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1274 Changed license of CCL module to 'Revised BSD'. After consultation with
1275 remaining members of the original EUROPAGATE consortium, we are re-issuing
1276 the CCL module without a separate license. The software was developed by
1277 Index Data as part of a research project. The special license was included
1278 to help feed usage information back to the project consortium to support
1279 project evaluation. At this time, the project consortium has long-since
1280 disbanded, and the majority of the original principals have retired. At the
1281 same time, we have significantly modified the software during the following
1282 years, to the point where very practically no original code remains. To
1283 simplify re-use of the software, we have contacted those members of the
1284 consortium who could be reached, and agreed to re-issue the module as a
1285 proper part of the YAZ package.
1287 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1289 CQL closer to being version 1.2 compliant. CQL also allows free-form
1290 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1293 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1294 bug could make Extended services handling crash in the ZOOM layer. This
1295 bug was only present in YAZ 3.0.18.
1297 --- 3.0.18 2007/12/19
1299 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1302 yaz-marcdump reads and writes collection wrapped records.
1304 Handle OPAC for record conversion module.
1306 Fixes for ICU wrapper.
1308 Allow ICU libs to be controlled with --with-icu .
1310 --- 3.0.16 2007/11/12
1312 Added yaz_poll which is a wrapper for select/poll. When poll is available
1313 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1314 sockets to be in use.
1316 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1317 functionality through an XML based configuration (ICU chain). This system
1318 is useful for search facilities such as Pazpar2 and Zebra that needs to
1319 perform tokenization of indexed material. The ICU code in a separate
1320 library libyaz3_icu.a.
1322 Added HTTP tunnel facility for COMSTACK, bug #1752.
1323 This is a facility that allows a Web proxy, such as squid, to tunnel
1324 Z39.50 traffic. This facility is "transparent" to must applications
1325 using YAZ. It's enabled by using pseudo transport connect: followed by
1326 the proxy address, followed by command, then follwed by he regular
1327 "virtual" addresss. For example,
1328 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1330 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1332 --- 3.0.14 2007/09/21
1334 Fixed bad memory reference in ZOOM_record - cuased by member not being
1335 initialized. This was a problem only in YAZ 3.0.12.
1337 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1338 fields were not removed.
1340 Changed the way C code is generated from codetables.xml. Made a MARC-8
1341 conversion trie for each characterSet section rather than codeTable.
1342 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1343 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1345 --- 3.0.12 2007/09/12
1347 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1348 from ZOOM_record_error).
1350 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1352 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1354 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1356 Better SRW-to-Bib-1 diagnostic mapping.
1358 ZOOM C and yaz-client announces SRU version 1.2 by default.
1360 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1363 Fixed in yaz_sru_decode to allow other version than 1.1.
1365 --- 3.0.10 2007/08/22
1367 Added support for SRU scan for ZOOM.
1369 Added support for the use of the older versions or Extended Service
1370 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1371 set to the version , 1=first, 2=second, 3=third. The third version is
1372 what ZOOM C has used so far. And that, obviously, is the default.
1374 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1375 therefore in Zebra and in SimpleServer-based applications). The new
1376 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1377 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1378 which is passed into the back-end search callback function.
1380 Added support for HTTP Basic authentication in clients: the SRU/W
1381 codec encodes the username/password elements of the PDU structure
1382 appropriately, and these may be set using the "user" and "password"
1383 options in ZOOM-C applications (the same options that are used for
1384 Z39.50 authentication).
1386 --- 3.0.8 2007/06/25
1388 Fixed bug #1208: SSL appears to be broken in ZOOM.
1390 Fixed bug #1206: Libxml2 include path weirdness.
1392 Added oid_name_to_dotstring.
1394 Allow elementSetName to be specified for ZOOM C record update.
1396 Allow waitAction to be specified for ZOOM C based for Extended Services.
1398 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1399 syntax OID. Bug introduced in YAZ 3 series.
1401 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1403 --- 3.0.6 2007/06/06
1405 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1406 directory. yaz-client now reads commands from file given by option -f
1407 if specified; then tries to read .yazclientrc in current directory.
1408 Failing that, it reads .yazclientrc from user's home directory.
1410 Added support for correlationInfo Note and ID for Record Update via
1413 Added yaz-client command querycharset which specifies character set for
1414 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1415 (termListAndStartPoint).
1417 Charset ISO5428:1984 is an alias for ISO5428-1984.
1419 Implemented a way to perform scan in a result set using Z39.50. This
1420 is achieved by attaching the result set name in the characterInfo
1421 (type InternationalString) of OtherInformation in the Scan Request PDU.
1422 The result set is identified in the otherinformation by the new OID:
1423 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1424 This allows for scan in result set and faceted search . Zebra did some
1425 of this in the APT term using attribute type 8 and value being result
1426 set. Using the OtherInformation approach for this is cleaner and easier
1427 to work with in proxies and the like. This facility can be used in
1428 yaz-client using new command setscan which takes a result set as first
1429 argument, start position (APT) as second.
1431 Changed decoding of SRU XML packed records to deal with servers that
1432 have recordData with XML data with multiple root nodes. Also make
1433 comparison for recordPacking case insensitive. Again, one server
1434 returns "XML" where others return "xml".
1436 For SRU responses allow Content-Type application/xml as well as text/xml.
1438 --- 3.0.4 2007/05/21
1440 Fixed bug in character set conversion of BER strings. Bug introduced
1443 --- 3.0.2 2007/05/08
1445 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1447 For OID class, use oid_class consistently.
1449 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1452 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1453 character set for bibliographic information interchange". By Giannis Kosmas.
1455 Added documentation on new OID API.
1457 --- 3.0.0 2007/05/02
1459 Changes to generic frontend server interface: added new member
1460 'query_charset' for bend_initrequest structure. A backend init handler
1461 should set this member to its native character set for query terms.
1462 When defined, the frontend server logic will announce this character set
1463 to a client if the negotiationModel bit is set by the client. All server
1464 implementors are encouraged to specify this. If a backend server does not
1465 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1467 Added CCL utility to remove terms (stop words) from resulting RPN
1468 tree. This is handled by functions with prefix ccl_stop_words_ .
1470 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1471 terms in RPN queries.
1473 Clean-up the CCL API. Moved some internal structures from ccl.h to
1474 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1475 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1476 This is replaced by ccl_parser_find_str which takes a string instead.
1478 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1479 libyaz.la is the core of YAZ except the generic frontend server and
1480 does not depend on POSIX threads anymore. libyaz_server.la is the
1481 generic frontend server facilities and uses POSIX thread functionality
1482 if available. The libyaz.la no longer depends on POSIX threads because
1483 the number of global structures is limited. NMEM no longer re-uses blocks
1484 between threads ; it simply free's memory immediately but allocates in
1485 "large" chunks as usual. We don't expect any performance penalties
1486 because of this. The yaz_log system is still using a global log_level so
1487 caution must be taken when modifying it with yaz_log_init_.. +
1488 yaz_log_mask_str. This, however, should not cause any trouble because
1489 these functions are called during initialization of application code
1490 anyway. `yaz-config --libs server` returns libs for server applications;
1491 `yaz-config --libs` returns libs for non-server applications.
1493 New OID database - with public definitions in oid_db.h. Removed old OID
1494 database including the head oid.h and definitions such as enum oid_value
1495 and struct oident. The new OID database uses the same string names as
1496 before but the 'protocol' is gone. There are now only two representations
1497 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1498 converts from string to OID; functions with prefix yaz_oid_to_string
1499 converts the other way.
1501 Change to emit_term() in CQL-to-PQF query translation: when a term has
1502 the /regexp relation modifier, do not process it for leading and
1503 trailing "^" and "*", which have quite different meanings in regular
1506 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1507 write handlers no longer carries a 'last' parameter. This will make
1508 yaz_iconv flush "less" characters. A flush is performed by call to
1509 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1511 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1512 removed, because function yaz_query_to_wrbuf does the same.
1514 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1515 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1517 Deprecated MARC utility functions removed.
1519 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1522 Branch split: YAZ_2_1_55_branch
1524 --- 2.1.54 2007/03/16
1526 Fix to ZOOM-C so that transparent reconnection is properly handled on
1527 connections that are in asynchronous mode.
1529 Fixed compilation on OpenBSD 4.0.
1531 Large strings in GRS-1 records are now properly displayed in yaz-client.
1533 Added character conversion support for "advancegreek"; based on patch from
1536 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1537 sequence is met. Before the error was not set so it would be unknown.
1539 Adjust yaz-marcdump MARC reader so that it skips until record separator
1542 --- 2.1.52 2007/03/07
1544 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1545 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1546 fd_set structure used as a bitmask for the FDs to be selected on.
1548 Using ACX_PTHREAD macro to check for POSIX threads.
1550 Fixed have-vsnprintf check.
1552 --- 2.1.50 2007/02/23
1554 Fixes for configure on BSD. Bug #900.
1556 Added snprintf/vsnprintf wrappers for systems that don't have
1557 limits (heavens forbid).
1559 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1560 created before all previous tasks were completed and removed from the
1561 task queue, the new task could be removed by a mistake.
1563 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1565 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1567 Fixed bug #832: Problem with MARC/charset in yaz-client.
1569 Fixed bug #668: save command line history for yaz-client.
1571 Fixed bug #830: pkg-config support.
1573 --- 2.1.48 2007/01/23
1575 Extended ZOOM result set options with two options that may be read by
1576 a client: resultSetStatus and presentStatus with values as specified for
1578 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1580 Fixed bug #827: Using SSL fails on Debian etch.
1582 Fixed bug #826: Weird looking chars for set of MARC records.
1584 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1585 that is treated as an ItemOrder with itemRequest being an XML document
1586 external. The value of "doc" is the content.
1588 Extended the GFS search facility. New member of bend_search_rr
1589 'estimated_hit_count' signals that hits is known to be an estmate
1590 (higher or lower than real hit count). New member 'partial_resultset'
1591 signals that the search was partial (hit count is lower or equal than
1592 real hit count). For Z39.50, the information is stored in resultSetStatus
1593 member of SearchResponse APDU. For SRU, the information is signalled
1594 via SRU diagnostic 59: "Result set created with valid partial results
1597 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1599 --- 2.1.46 2007/01/13
1601 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1603 Added ZOOM_connection_peek_event.
1605 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1606 the following new functions:
1607 ZOOM_event_nonblock, ZOOM_connection_process,
1608 ZOOM_connection_get_{socket,mask,timeout},
1609 ZOOM_connection_fire_event_{timeout,socket}.
1610 The existing blocking event handler, ZOOM_event, is a wrapper for the
1611 + blocking ZOOM_event_sys_{poll,select}.
1613 Implemented function ccl_xml_config which parses XML version of CCL
1614 configuration (bug #798).
1616 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1618 Added timings utility (yaz/timing.h)
1620 --- 2.1.44 2007/01/03
1622 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1625 Fixed bug #779: Rotation of apdu.log fails.
1627 Fixed for character set conversions:
1628 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1629 Honor G1 set in MARC-8 decoding.
1631 --- 2.1.42 2006/12/17
1633 Fixed bug #775: char conversion does not handle Alternative UTF-8
1636 Implemented function yaz_marc_read_line which parses MARC line format
1637 records. There is a wealth of formats out there. So far, this function
1638 reads line records produced by yaz_marc_write_line.
1640 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1641 more generic and easier to remember(!) options: -i format and -o format
1642 which specifies input format and output format respectively - where
1643 format is one of "marc", "marcxml", "line", "marcxchange".
1645 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1646 does not print anything except warnings for records.
1648 For yaz-marcdump, added support for MARC split into files (-s) with a given
1651 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1652 spec, at http://www.loc.gov/standards/sru/record-update/
1653 This has changed the binary layout of the following structs:
1654 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1655 bend_update_rr . Patch by Ko van der Sloot.
1657 Added GFS utility function bend_assoc_is_alive which returns 1 if
1658 association is still alive (client is connected); 0 otherwise (client
1659 closed connection). This allows busy servers to stop working for
1662 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1663 been a separate piece of software. This version of ziffy has been modified
1664 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1666 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1668 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1669 Client code may now interrogate options such as "init_opt_sort" to
1670 find out whether the server claims to support various options.
1672 --- 2.1.40 2006/11/27
1674 Added utilities yaz_{set,get}_esn to set/get element set name from
1677 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1678 of YAZ and has been so since YAZ 2.1.10.
1680 Implemented ZOOM_record_error which returns error information for
1681 record (surrogate diagnostic).
1683 --- 2.1.38 2006/10/31
1685 Updates for SRU Update by Ko van der Sloot:
1686 1. Changed name from "operation" to "action"
1687 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1688 versions in the code, marked as 'backward compatible'.
1689 3. Added diagnostics for SRU Update.
1691 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1693 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1695 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1697 For GFS, fixed problem with SRU diagnostic 'First record position out of
1698 range' being issued for 0 hits.
1700 zoomtst10 part of Windows Build.
1702 --- 2.1.36 2006/10/13
1704 Implemented yaz_filepath_comp which splits a path into file path
1705 components (required by Zebra 2.0.3+).
1707 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1708 BSD inspired license until now so this should not have any real impact on
1709 anybody. See http://www.opensource.org/licenses/bsd-license.php
1711 Fixed bug #687: Missing log lines.
1713 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1716 Fixed bug #689: SRU diagnostics to be added.
1718 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1719 whether a connection is idle (no more work do do).
1721 --- 2.1.34 2006/10/04
1723 Change type of optval from long to int for invocation of setsockopt with
1724 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1726 Added support for specifying the max log file size for the Generic
1727 Frontend Server. The size is given with option -r.
1729 --- 2.1.32 2006/09/21
1731 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1733 --- 2.1.30 2006/09/17
1735 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1738 Fixed bug in Generic Frontend Server that could cause a server to stop
1739 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1741 For the generic frontend server, the maximum record size is used as maximum
1742 size of incoming packages (SRU + Z39.50). The value until was previously
1743 only used in Z39.50 Init negotiation and, later, in a session controlled
1744 sizes of records returned. This is controlled using -k option. It can be
1745 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1747 --- 2.1.28 2006/09/04
1749 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1752 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1754 New option for yaz-marcdump -lpos=value which allows setting a portion
1755 of MARC header to a certain value.
1757 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1759 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1760 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1762 --- 2.1.26 2006/08/15
1764 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1767 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1769 --- 2.1.24 2006/08/08
1771 Fixed MARC ISO2709 encoding routines to deal with character set
1774 Minor changes to GFS logging. Database included in search request log
1777 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1778 cached/multiple records.
1780 Shared libraries are built by default on Unix+configure.
1782 Changed cql2pqf transformation to use a different evaluation order. The
1783 new order is: always, relation, structure, position, truncation, index
1784 and relationModifier. Old order was: always, relation, relationModifier,
1785 structure, index, position, truncation. Note that the the latter ones
1786 override former ones for identical attributes.. The new scheme means that
1787 it is possible to override any existing attribute with a relationModifier.
1788 And also that it is possible to override everything for the index rule
1789 (except the ones listed in relationModifier). No order is perfect but this
1790 one, we believe, covers more real cases.. The "always" should have been
1791 called "default", since the attributes there can be overridden with all
1794 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1795 compilation phase, but also for yaz-config --cflags output. This allows
1796 us to have public headers with Libxml2 stuff in them . It should also,
1797 eventually, make Libxml2 checks redundant in packages using YAZ, such
1800 --- 2.1.22 2006/06/15
1802 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1803 stored in uri, message and details.. Previously diagnostics were stored
1804 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1805 compatibility.. but he's probably the only one affected, so.
1807 Added support for CCL, compiled on the client side, in ZOOM-C. This
1808 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1809 input; the resulting query objects can be used for for searching with
1810 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1812 YAZ' configure searches for OpenSSL by default.
1814 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1815 SL_CTX_use_certificate_file. See
1816 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1817 for more info. Thanks to Ko van der Sloot.
1819 --- 2.1.20 2006/06/02
1821 Bug #600: SRU GET, POST support for yaz-client. Introduced
1822 command 'sru' which selects method SOAP/GET/POST.
1824 Allow missingValueAction to be specified for the sortspec string -
1825 function yaz_sort_spec. By default, the missing value action is null.
1826 Use ! to specify "abort". Use = followed by stringvalue to specify default
1829 Ensured that Present-handler (if defined) is called in GFS before any call to
1830 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1831 searchRetrieve requests.
1833 Documentation for YAZ is now based on the Docbook XML/XSLT using
1834 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1835 is no longer depending on jade/openjade or docbook-to-man scripts.
1836 PDF is no longer part of the distribution - but can optionally be
1837 made using DSSSL/jadetex or FOP.
1839 Added retrieval handling support in Generic Frontend Server to support
1840 conversion between MARC/XML as well as XSLTtransforms. See
1841 etc/yazgfs.xml for an example.
1843 Added Authentication support to Generic Frontend Server in SRU
1844 mode. Authentication using HTTP Basic is supported, as is the use
1845 of 'x-username' and 'x-password' parameters in the request itself.
1847 Added support for a new character set MARC8s identical to MARC8 except
1848 that it converts combined characters to single Unicode characters in the
1849 Latin-1 range (when possible).
1851 --- 2.1.18 2006/04/24
1853 ASN.1 compiler 0.4: generates brief Doxygen file header for
1854 generated .h/.c files.
1856 Utility yaz_iconv now supports conversion to MARC-8.
1858 New facilities for the MARC module. The reading - and writing of
1859 content are separate methods for the yaz_marc_t handle. The following
1860 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1861 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1862 format). Write functions have prefix yaz_marc_write_.. The existing
1863 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1864 available. Removed support for OAI-MARC and simplexml (not the
1865 simplexml from PHP5).
1867 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1868 to be returned for this connection.
1870 --- 2.1.16 2006/03/31
1872 Allow multiple languages and charsets to be specified with
1873 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1874 negcharset iso-8859-1,utf-8
1876 Translation of proximity nodes from CQL into PQF now works.
1878 Moved to automake 1.8, 1.9.
1880 Added function yaz_log_set_handler which allows a log handler to be
1881 installed. This handler will be called for all log messages. Output
1882 to file is also produced; but that can be disabled by passing NULL
1883 fname to yaz_log_init_file.
1885 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1887 For SRW (including GFS), accept application/soap+xml as content-type
1890 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1891 produces NO stylesheet reference even if a default stylesheet is specified
1894 --- 2.1.14 2006/03/14
1896 Updated Windows package to include yazd.dll + yazd.lib for the
1897 Development component.
1899 If the environment variable YAZ_LOG is set, then it is used as a
1900 string indicating the default level of logging to use if not
1901 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1902 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1903 used as before. So, for example, to omit warnings from YAZ logging,
1904 export YAZ_LOG=-warn
1906 cql_transform() now map structure and other attributes before indexes,
1907 so that index-specific structures and other attributes can override
1908 defaults. So now a combination of mapping specifications such as:
1910 index.dc.date = 1=date-modified 4=5
1911 does the right thing.
1913 cql_transform() now also respects the "always" mapping specification,
1914 which establishes an initial set of attributes to be used for all
1915 terms except where overridden by more specific attributes associated
1916 with the index, relation or modifier.
1918 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1919 which mode to use; one of "post", "get" or "soap" (SRW, default).
1921 Fixes for yaz_iconv routines: changed trie-based character set conversions
1922 to use only non-negative values for bit fields due to Sun's C compiler not
1923 supporting negative values.
1925 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1926 sequences where not read correctly. Fix by Rustam Usmanov.
1928 Updated win/makefile to use options, settings which makes things
1929 compile with VS C 2005.
1931 --- 2.1.12 2006/02/01
1933 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1935 In ZOOM socket code, use select instead of poll on MacOSX.
1937 ZOOM-C now support client-side compilation of CQL into RPN that is
1938 sent to the server, enabling CQL to be used against all Z39.50
1939 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1940 ZOOM_query object, and submit it using ZOOM_connection_search().
1941 The CQL-to-RPN translation uses a configuration file, the name of
1942 which must be specified in the Connection's "cqlfile" option.
1944 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1945 function, which takes as its start-term parameter a ZOOM_query object
1946 (which may have had either CQL or RPN set into it).
1949 --- 2.1.10 2005/11/29
1951 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1952 GFS to support this as well. Backend handler, bend_srw_update, does the
1953 update work. Code contributed by Ko van der Sloot.
1955 Allow retrieval of Search Result-1 information in ZOOM by the use of
1956 options that are attached to a result set. ZOOM documentation updated
1959 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1960 UTF-8 conversion. Patch by Raj Patel.
1962 Added option -m to GFS to control formatting of timestamps in log file.
1964 Added 'exit' as synonym for 'quit' in yaz-client
1966 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1967 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1968 for the new members. Patch by Ko van der Sloot.
1970 Added support for SRU POST. It is supported for content-type
1971 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1973 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1974 Instead make the library libyaz.la multi-threaded. Threading as a whole
1975 can still be disabled by configure option --disable-threads. Previosly,
1976 with older GLIBCs there were problems with MT libs under Apache. This
1977 has now been fixed a long time ago.
1979 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1982 CQL module modified to be case insensitive for relations/indexes/operations.
1984 Fixed bug in CQL transform code: incorrect value relationModifieder
1987 Added 'show all' command for yaz-client which retrieves all results
1990 Added new yaz-client, xmles, which takes a (private) OID and
1991 a document to be sent as an extended service request.
1993 Describe new yaz-client commands wait_response and set_auto_wait.
1995 Increase TCP/IP listener backlog from 3 (which I am guessing was
1996 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1997 that the socket will queue as many incoming connections as it's able
1998 to handle ongoing connections. In other words, it will never now
1999 refuse a connection that it would be able to handle merely because
2000 it's not got around to accepting() enough of the pending connections
2001 yet. This is the behaviour anyway under Linux, where the listen()
2002 argument is ignored; but not under BSD and on systems such as
2003 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2004 YAZ-based servers should now be uniform across operating systems in
2007 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2008 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2009 This allows yaz-marcdump to read large MARC batches (>2 GB).
2011 Modified all YAZ source files - except the source which is auto-generated
2012 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2015 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2016 corresponding to the existing *_setl() function. These allow option
2017 values containing arbitrary valuues.
2019 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2020 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2021 except that it returns an indicator of whether or not the sort
2022 criterion was accepted (0 for OK, -1 for invalid).
2024 --- 2.1.8 2005/06/07
2026 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2027 MARC output rather than returning "new" buffer.
2029 yaz-client warns about unknown init options.
2031 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2033 --- 2.1.6 2005/05/24
2035 Added support for SRW sort in Generic Frontend Server. Patch
2036 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2037 sortKeys - or NULL if none is provided.
2039 Fixed bug #307: It was impossible to specify indefinite/no timeout
2040 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2043 Added support for multiple languages and charsets to be specified in
2044 ZOOM. Each charset/language is separated by a blank. If negotiation is
2045 in effect in init-response, Option
2046 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2047 Code based on patch by Vasiliy Osadchuk.
2049 Fixed bug #306: infinite recursion that occurred when calling
2050 yaz_log_level_init as the first call (before other log level or
2053 Fixed bug in scan handling in front end server: if preferred-Position-In-
2054 Response was non-present, a NULL pointer referece was performed.
2056 --- 2.1.4 2005/04/26
2058 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2059 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2060 now defined for all those error codes. So instead of putting 109 in
2061 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2062 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2064 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2067 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2069 Program yaz-client now exits and produces an error message if multiple
2070 Z39.50 servers are specified on the command line (none or one allowed
2073 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2076 --- 2.1.2 2005/03/16
2078 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2080 Fixed bug #272: Preserve spacing for CCL terms.
2082 --- 2.1.0 2005/03/14
2084 Added support for virtual hosts and multiple backend servers for
2085 the YAZ frontend server. The configution is XML based and
2086 support specificition of CQL to RPN mappings and explain information.
2087 See section "Virtual Hosts" in the YAZ manual.
2089 Extended OPAC display utility. OPAC display utility renders
2090 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2091 to supplement yaz_marc_decode_wrbuf.
2093 Fixed a bug in MARC decoder that could caused it to crash for some
2094 invalid MARC records. More diagnostics and warnings where added in
2095 XML output (warnings, etc are stored in comments).
2097 --- 2.0.34 2005/02/08
2099 Fixes for UNIX domain sockets. Bug #261.
2101 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2103 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2104 Added yaz_marc_subfield_str which defines subfield lead string which is
2105 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2106 yaz_marc_endline_str which defines end of fields string used in
2107 YAZ_MARC_LINE format. Default string is newline.
2109 Experimental support for MarcXChange. This format can be produced
2110 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2111 http://www.bs.dk/standards/MarcXchange.xsd
2113 Added yaz-client commands scansize that sets maximum number of
2114 entries to be returned by scan.
2116 --- 2.0.32 2005/01/11
2118 Added support for SRW scan in yaz-client and Generic Frontend Server.
2120 * Added whereInList member to SRW Scan Term.
2122 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2124 Fixed NMEM system to return aligned blocks on the smallest boundaries
2125 that are suitably aligned for all possible types on the particular
2126 architecture YAZ is being built for.
2128 --- 2.0.30 2005/01/04
2130 Fixed numerious warnings that was issued with newer versions of GCC.
2132 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2133 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2136 Make YAZ Generic Frontend Server slightly faster.
2138 Enhance (and reduce) logging for Generic Frontend Server.
2140 Revert YAZ log system so that it flushes every write operation
2141 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2143 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2144 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2145 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2146 will effectively disable old definitions.
2148 --- 2.0.28 2004/11/09
2150 Added yaz_log_time_format which specifies log format using
2153 Added yaz_log_module_level which returns mask for a module. Value
2154 is non-zero mask a if module is enabled; zero if disabled.
2156 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2157 in include/yaz/cql.h.
2159 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2161 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2163 Fixed bug #172: RPM builds does not enable SSL.
2165 Doxyfile.in part of dist. Doxyfile generated by configure.
2167 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2168 are given and the corresponding component does not exist.
2170 Extend CCL documentation in YAZ reference. Describe r=r.
2172 --- 2.0.26 2004/10/01
2174 Fixed MARC->MARCXML conversion to properly deal with
2175 fields, subfields, indicators having non-ASCII characters.
2177 Fixed MARC->MARCXML conversion so that ASCII control characters
2178 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2181 Added YAZ GFS support for conversion from Z39.50 surrogate
2182 diagnostics to SRW surrogate diagnostics.
2184 Bug fix: YAZ GFS did not return schema in explainResponse.
2186 --- 2.0.25 2004/09/30
2188 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2189 now converts recordSchema to elementSetName as well as schema URI.
2191 Fixed bug in COMSTACK that prevented HTTP request packages from being
2194 --- 2.0.24 2004/09/29
2196 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2197 does not require white-space before and after the dash in a range, e.g.
2198 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2201 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2202 due to new GCC removing "redundant" code.
2204 Added yaz-client commands scanpos and scanstep that sets preferred
2205 position and step-size for scan.
2207 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2209 Added CCL utility ccl_qual_buf which parses one or more CCL
2210 spec lines in a buffer.
2212 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2213 of name and value - ignoring empty lines and comments.
2215 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2217 Added odr_get_element_path which returns current element path for an
2218 ODR handle. This utility is useful in error handling or user-defined
2221 Added ODR_PRINT utility odr_set_stream which is is a more generic
2222 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2223 to a write function and pointer to close function. The close function - if
2224 non-NULL - will be called during odr_destroy.
2226 Fixed bug in CCL parser where truncation char was not removed from
2227 right side when truncation=both was in effect.
2229 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2232 --- 2.0.23 2004/08/11
2234 Fix buffer overrun in CQL parser when dealing with proximity (%).
2236 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2237 to UTF-8/UCS conversion is now only based on codetables.xml.
2239 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2241 --- 2.0.22 2004/08/06
2243 Add support for more "commit changes" in ZOOM (uses Extended Services).
2245 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2248 Yet another small fix for configure of SSL.
2250 --- 2.0.21 2004/05/14
2252 Fix SSL libs for configure when --with-openssl=DIR is given.
2254 --- 2.0.20 2004/05/10
2256 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2258 SSL comstack now uses yaz.pem certificate file on server side
2259 by default. Certificate filename can be configured by calling
2260 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2262 Fix bug regarding multiple calls to ZOOM_connection_connect.
2264 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2266 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2267 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2269 ZOOM now allows inspection of X509 peer certificate for verification.
2270 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2272 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2273 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2274 as "modular" but it simplifies things.
2276 Added cs_get_peer_certificate to that returns peer X509 PEM.
2278 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2279 NULL if SSL is unavailable.
2281 Documentation about MARC decoding tools.
2283 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2285 --- 2.0.19 2004/03/30
2287 Rename CHANGELOG to NEWS to follow GNU style packing.
2289 Fix bug with missing initialization of member in init_diagnostics.
2290 This bug affects threaded version of GFS server.
2292 --- 2.0.18 2004/03/20
2294 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2297 Ensure zlib.dll is packed with Windows install.
2299 --- 2.0.17 2004/03/17
2301 Fix encoding of xsd:string to use text instead of CDATA.
2303 Fix endless loop in CQL parser with unbalanced ".
2305 Use a more compact way to store MARC-8 conversion tables.
2307 --- 2.0.16 2004/03/16 Debian only
2309 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2312 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2317 --- 2.0.15 2004/03/01
2319 Another fix for decoding of XML packed records.
2321 --- 2.0.14 2004/02/25
2323 Fixes for Chunked encoding. White space not ignored after length spec.
2325 Update NS and use default NS for SRW diagnostic elements.
2327 --- 2.0.13 2004/02/23
2329 Implement ZOOM_resultset_cache_reset which resets record cache.
2331 Implement ZOOM_resultset_sort which sorts a result set.
2333 Implement chunked HTTP transfer.
2335 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2337 --- 2.0.12 2004/02/16
2339 Added member 'schema' to bend_explain_rr structure so that backend
2340 can specify explain record identifier. Defaults to Zeerex 2.0.
2342 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2344 --- 2.0.11 2004/02/16
2346 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2349 Added init command for yaz-client which sends "extra" init request.
2351 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2352 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2354 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2356 Make ZOOM error code for "invalid query".
2358 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2360 --- 2.0.10 2004/02/05
2362 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2365 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2367 Added option -p <file> to make Generic Frontend Server to write PID file.
2369 Added option -D to put Generic Frontend Server in background on its own.
2371 Make ZOOM C recognize option "password". If unset, "pass" is used
2372 (for backwards compatibility).
2374 Fixed a bug in Generic Frontend Server that could make it crash if a
2375 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2378 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2379 Must be issued before open, in order to be in effect.
2381 --- 2.0.9-6 2004/01/12 Debian/Windows
2383 Make the SRU server more picky WRT unknown params, etc.
2385 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2387 New YAZ client command, options, that sets Z39.50 options.
2389 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2390 options from a string of tokens (one token for each option bit).
2392 Update SRW diagnostic code messages.
2394 --- 2.0.9-5 2004/01/07 Debian/Windows
2396 Handle user defined stylesheet for SRW/SRU.
2398 --- 2.0.9-4 2004/01/06 Debian/Windows
2400 Fix bug in decoding of Content-Length.
2402 --- 2.0.9-3 2004/01/06 Debian/Windows
2404 Fix a bug with decoding of XML packed records.
2406 --- 2.0.9-2 2004/01/05 Debian only
2408 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2410 Fix bug in SRW/SRU diagnostics decoding.
2412 --- 2.0.9 2004/01/05
2414 Fixed bug in Generic Frontend Server which could drop records exceeding
2415 preferred message size. Reported and fixed by Irina Dijour.
2417 Fixed calculation of package size for structured records in Generic
2418 Frontend Server. Reported and fixed by Irina Dijour.
2420 Fixed namespace for SRW/SRU diagnostics.
2422 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2424 --- 2.0.8 2003/12/22
2426 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2427 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2430 CQL changes to reflect recent changes to the specification:
2431 * Documentation talks about context sets instead of index sets.
2432 * Documentation talks about indexes instead of qualifiers.
2433 * The CQL-to-PQF transformer's configuration file now uses
2434 "index.set.name = <attributes>" instead of the old form
2435 "qualifier.set.name = <attributes>". (Both forms are still
2436 understood but the latter is deprecated.)
2437 * CQL terms with no explicit index specified are now interpreted as
2438 cql.serverChoice instead of srw.serverChoice (which of course
2439 behaves exactly the same.)
2441 --- 2.0.7 2003/12/16
2443 MARC conversion can now generate ISO2709 output in another
2444 character set. yaz-marcdump uses this facility if you invoke it
2447 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2448 functions from there can be used from C++.
2450 --- 2.0.6 2003/12/04
2452 Frontend server now transfers memory from decoded packages to stream
2455 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2456 references to show up.
2458 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2459 the ZOOM Abstract API. The older names for the same options are still
2460 also supported for the benefit of old applications.
2462 ZOOM-C supports "implementationId" and "implementationVersion" options
2463 to go along with "implementationName". These allow the user code to
2464 specify identification strings to be sent to servers.
2465 Add OID for the new ExtLite attribute set.
2467 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2468 as requested/supplid by Ere Maijala <ere@atp.fi>
2470 For generic frontend server, reverse the order of
2471 "toolkit-supplied / application-supplied" strings sent as implementationId,
2472 Name and Version. Also, remove the spaces around the slash. This brings
2473 the GFS in line with the behaviour of ZOOM-C on the client side.
2475 Add function ZOOM_scanset_display_term.
2477 yaz-client shows scan displayTerm if present.
2479 Utility yaz-iconv is now installed by default along with the man page
2482 Extend configure check for OpenSSL to use pkg-config where available (such
2485 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2486 server to specify uid/gid/mask for socket using the format
2487 unix:[user=uid,][group=gid,][umask=mask,]file=path
2488 If file= is omitted the existing format is assumed, e.g.
2490 in which case the mask is 0666 (rw for everybody).
2492 Major restructure of YAZ source. All source in libyaz is in src directory.
2493 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2494 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2496 Added man page for utility yaz-marcdump (used to be called marcdump).
2497 yaz-marcdump is installed by 'make install'.
2499 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2500 of incoming package failed.
2502 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2504 Change prototype of odr_perror: add const to message string.
2506 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2508 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2509 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2510 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2511 DNS lookup. There should not be any compatibility problems with this
2512 assuming that blocking=1 or 0 is used.
2514 Fix bad reference in UNIX comstack in function cs_addrstr.
2516 Fix for compilation on AIX.
2518 The generic front-end server (server/seshigh.c) now supports returning
2519 Init diagnostics to the client in User-information-field, in
2520 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2523 --- 2.0.4 2003/09/04
2525 Allow any CQL relation (not just all,any,exact,scr).
2527 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2528 that features the same UI.
2530 Implemented command update0 in YAZ client which is equivalent to
2531 update but uses old of Ext Update ASN.1.
2533 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2534 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2535 Previously no OID was used for this info.
2537 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2538 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2539 returns 'malformed search term' otherwise.
2541 SortResponse member resultCount now set to NULL in sort handler of
2544 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2547 Add three new utility functions for translating OIDs between various
2548 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2549 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2550 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2551 char *oid_to_dotstring(const int *oid, char *oidbuf);
2552 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2554 Reverted modifications for ES Update definition for z_IU0Update
2555 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2556 is back to YAZ 2.0.2.
2558 String value attributes for CCL parser.
2560 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2561 which their FirstSearch server returns in Init responses, sometimes
2562 carrying useful diagnostic information when Init fails. This has the
2563 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2564 "z39.50/oclcui.asn", where its definition is somewhat different from
2565 what OCLC document on their web-site, as required to interoperate with
2568 Support for anonymous authentication in yaz-client. Use the command
2571 * Fix the OID of the Index Data-local "admin" Extended Service from
2572 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2573 the 1000, which indicates a locally-defined OID, was a mistake.
2575 --- 2.0.3 2003/06/20
2577 Fix CCL directive @case handling so that it affects string match for
2578 both CCL keywords and qualifiers.
2580 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2581 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2582 Decoder has been updated with ASN.1 changes as listed in
2583 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2584 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2585 z_IUUpdate, remains unchanged.
2587 ZOOM_record_get may now return a record in a specific character set.
2588 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2589 "from" is the character set of record as returned by target. "to" is
2590 the character set to be returned. If omitted, "to" is UTF-8.
2592 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2594 New ODR utility, odr_getelement, which returns name of element for
2595 which encoding/decoding failed.
2597 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2598 in cases where a required element was omitted.
2600 Bug fix: some MARC8 sequences were not converted.
2602 New ZOOM option "step" which specifies number of records to be
2603 retrieved in one chunk. Used in conjunction with "start" and "count".
2605 SRW support for yaz-client. Use scheme http: to use it, e.g.
2608 yaz-client no longer does (un)intelligent character set conversions
2609 by default. Can be enabled with charset and marc_charset commands.
2611 xmalloc trace fix for 64-bit systems such as DEC alpha.
2613 Solaris 2.6 compile fix.
2615 New function, cql_strerror() translates SRW error codes, as returned
2616 by cql_transform_error(), into human-readable English strings. Used
2617 in yaz-client diagnostics when appropriate.
2619 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2620 converts it into a type-1 query which is sent to the server. This
2621 makes CQL available for use with all Z-servers, as opposed to the tiny
2622 minority that can handle CQL queries themselves.
2624 --- 2.0.2 2003/04/28
2626 New Debian package layout similar to the Redhat Package layout.
2628 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2629 and search result respectively.
2631 --- 2.0.1 2003/04/25
2633 Redhat package is now several packages: libyaz (runtime libraries),
2634 libyaz-devel (development and documentation, and yaz (utility programs).
2635 Package spec file by Morten Bogeskov.
2637 New member 'schema' in struct bend_fetch_rr which the name of requested
2638 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2639 handler MAY set this to reflect the schema of the returned record.
2641 New member 'display_term' in struct scan_entry. GFS now sets member entries
2642 and allocates scan entries to be filled by user scan handler. In previous
2643 version, entries member was allocated by the scan handler. That still works,
2644 but the GFS will ignore member display_term - assuming it was NOT set by
2645 the handler. The fact that the GFS now allocates the entries both allows
2646 for new members and makes a scan handler easier to write.
2648 Fix CQL lex buffer overflow.
2650 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2651 SRU default recordPacking is string.
2653 SRU protocol support for frontend server.
2655 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2657 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2659 Added scan for the ZOOM shell (zoomsh).
2663 * String Identifers for Schemas (Amendment 5).
2664 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2665 Old definition for schema
2666 Odr_oid *schema; /* OPT */
2671 Z_InternationalString *uri;
2672 #define Z_Schema_oid 1
2673 #define Z_Schema_uri 2
2676 * resultCount parameter to Sort Response (Amendment 1).
2677 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2679 Support for SRW 1.0 over HTTP. This is an optional feature and
2680 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2683 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2684 on the same port. SRW SearchRetrieveRequests are mapped
2685 to bend_init,bend_search,bend_fetch,bend_close.
2687 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2689 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2690 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2692 ZOOM connections are SRW based if schem http is used for hostname
2693 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2694 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2696 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2697 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2698 distance=n, order=true/false, relation=le, prox unit=word. If
2699 n is omitted, distance 1 is used.
2701 Fixed problem with C compiler include path in wrong order.
2703 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2704 on Solaris. Patch from Ko van der Sloot.
2706 New MARC decode API. All new functions operate on a yaz_marc_t
2707 handle. The most important new functions are: yaz_marc_create,
2708 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2709 decode and destroy respectively. Decoder can produce formats
2710 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2711 include/yaz/marcdisp.h.
2713 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2714 to UTF-8, UCS-32, wchar_t or Latin-1.
2716 * Prototypes for yaz_iconv_-functions moved to separate header
2717 include/yaz/yaz-iconv.h.
2719 Make a few private functions 'static' in unix.c. This prevents
2720 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2722 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2723 are set when Init Response is received.
2725 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2726 but returns diagnostic set as well.
2728 New function yaz_strerror which is a portable wrapper for
2729 strerror/strerror_r/GetLastMessage.
2731 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2732 is returned for MARC. If type is "oai", then OAI MARC is returned.
2734 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2737 --- 1.9.2 2002/11/26
2739 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2741 Fix bad race conditions on SIGTERM and terminate gracefully in
2744 Move retrieval (data1) module to Zebra since nobody seems to be
2747 Add GRS-1 render for ZOOM using same format as yaz-client.
2749 --- 1.9.1 2002/10/05
2751 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2753 Fix broken ESpec handling in data1 module.
2755 SGML reader parses comments and makes them part of the data1 tree.
2757 Added several type casts so that YAZ compiles as C++ code.
2759 ZOOM didn't handle PDU encoding failures properly.
2761 Added more Bib-1 diagnostics (approved extensions).
2763 GNU configure: better check for iconv.
2765 More portable use of accept, getpeername. Check for socklen_t. Use
2766 int/size_t if socklen_t is not defined.
2770 PQF parser rejects bad queries - including those with extra
2771 characters in them. PQF parser used to silently ignore that.
2772 Cleaner API for PQF added, which allows you to get detailed
2773 error information for bad queries (see yaz/pquery.h).
2775 Fixed bug in ZOOM_record_get for type "database".
2777 Implemented mini iconv library supporting conversions between
2778 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2780 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2782 --- 1.8.9 2002/08/20
2784 Fixed ZOOM C record cache so that preferredRecordSyntax and
2785 elementSetName is used to check for already fetched records.
2787 --- 1.8.8 2002/08/02
2789 Added three members in bend_initrequest structure to facilitate
2790 character set negotiation.
2792 Fixed a bug in frontend server that could cause indefinite
2793 loops under rare conditions.
2795 Revised character set utilities (charneg.h) so that encoding
2796 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2798 For PQF, directive @term <type> sets term type for Scan/Search.
2799 Here <type> is general, string, numeric, null. The term type
2800 is inherited - just like @attr.
2802 New call odr_set_charset that sets character set conversion for
2803 international-strings on a ODR stream. Prototype is:
2804 int odr_set_charset(ODR o, const char *to, const char *from);
2805 The InternationalString is still represented as C string in YAZ
2806 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2807 won't). On the protocol level, you can use any encoding.
2809 Support for UNIX sockets in ZOOM.
2811 Solaris recv sometimes returns errno == ENOENT. It is treated as
2812 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2814 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2815 both client and server. Code by Morten Bogeskov.
2817 --- 1.8.7 2002/05/22
2819 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2820 that they can be used directly from Visual Basic. You must recompile
2821 your windows APP if you're using ZOOM.
2823 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2824 Commands "lang" and "charset" sets language and character set respectively.
2825 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2826 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2828 Attributes from multiple CCL fields may be OR'ed rather than merged
2829 using directive "@field or". Fields are still merged by default -
2830 equivalent to "@field merge".
2832 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2835 Fixed bug in zget for parameter ExtendedServicesResponse.
2839 --- 1.8.6 2002/03/25
2841 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2843 Client displays USR.1:SearchResult-1 (hits per term).
2845 Additional Search Info for search in Generic Frontend Server.
2847 Fixed CCL parsing of "field=s".
2849 WIN32 installer - using the excellent NSIS software from nullsoft.
2851 Fixed CCL parsing of "field = - <number>".
2853 Added function yaz_marc_decode that decodes MARC for line mode
2854 display or XML (similar to that used by JZKit).
2856 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2857 Z39.50. But ISO/ILL was, however.
2859 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2860 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2862 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2863 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2865 --- 1.8.5 2002/02/03
2867 New YAZ client features: Command completion and new commands:
2868 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2869 Code provided by Jacob Poulsen.
2871 New call oid_trav, that visits all registered OIDs via callback.
2873 Function ZOOM_record_get now returns const char pointer rather than
2874 void pointer. It saves a lot of type casts.
2876 For YAZ client, command "auth" now allows you to set authentication
2877 in IdPass style. It is enabled when three tokens are given - order
2878 is user, group and password.
2880 Fix memory leaks in MARC record handling for ZOOM.
2882 New option for YAZ client, -k <kilobytes> that sets
2883 maximum record size. Similar to -k option for generic frontend
2884 server and yaz-ztest.
2886 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2888 Prefix query parser reports "fail" when bad attribute set is given.
2890 Fix in MARC decoder. Proximity logging. Fix for attribute set
2891 in scan handler for server. Patches by Shigeru Ishida.
2893 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2896 Configure option --with-openssl=<dir> now works when a directory is
2897 specified. Patch provided by Morten Bogeskov.
2899 New option for YAZ client, -u <auth>, that sets authentication.
2901 ZOOM fix: error information was sometimes "missing", since error
2902 was cleared/reset too when it shouldn't.
2904 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2906 --- 1.8.4 2002/01/04
2908 Scan for ZOOM API. New object ZOOM_scanset. New functions
2909 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2910 ZOOM_scanset_destroy.
2912 New ZOOM function, ZOOM_connection_last_event, that returns type
2913 of last event (such as "receive data", "send data", "apdu received",
2916 New ZOOM option, schema, that specifies schema for retrieval.
2918 New CCL feature. Qualifiers can be aliases for one or more
2919 other qualifiers (if more than one is given, OR is used).
2921 ZOOM uses named result sets if target supports it.
2923 Two new YAZ client commands: . (dot, which sources a script of YAZ
2924 client commands), and ! (to execute shell command.). Implemented
2927 Working on Debian packages.
2929 --- 1.8.3 2001/11/19
2931 YAZ client enables named result sets only if target supports it.
2933 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2935 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2936 with key="host" to get same result.
2938 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2939 Function Z3950_resultset_record(s) returns references to records
2940 "owned" by resultset. To become owner use Z3950_record_clone.
2942 Function z_ext_record handles Extended Services. Thanks to
2945 --- 1.8.2 2001/11/12
2947 CCL Parser fix: ignore token comma when dealing with and-lists.
2949 Documentation updates for COMSTACK.
2951 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2952 Changed prototype Z3950_records. For some functions, int parameters
2953 were changed to size_t.
2955 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2958 New MARC decode/display function, marc_display_exl, which properly rejects
2959 non-ISO2709 records. YAZ client uses it.
2961 --- 1.8.1 2001/10/29
2963 Fix bug: local attribute set wasn't set correctly in PQF strings.
2967 * Old Z39.50 codecs no longer supported.
2969 Added ZOOM C binding. See http://zoom.z3950.org/
2971 Renamed states for COMSTACKs to avoid confusion with events.
2973 Implemented cs_look and proper cs_rcvconnect.
2975 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2977 Configure detects POSIX threads on OpenBSD.
2979 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2980 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2982 When error is returned from present handler, non-surrogate diagnostic
2983 is returned in present response (and fetch handler is no longer called).
2985 * Minor adjustments to pquery parser (PQF). Token characters may be
2986 escaped by using backslash (C-style).
2988 PQF parser allows string attribute values to be specified. For @attr,
2989 non-numeric characters after the equal-sign are treated as strings
2990 (e.g. @attr 9=title).
2992 CCL trunction character may be defined (@truncation in file)
2994 * function zget_ExtendedServicesRequest sets waitAction to
2995 waitIfPossible (was wait).
2997 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3000 CCL operator names may be set in field definition files (CCL_bibset).
3001 See ccl/bib1 for an example.
3003 Fixes in ASN.1 compiler for C++ compatibility.
3005 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3006 and "op_or" to avoid conflict with C++.
3008 Fixed problem with GNU readline detection on Redhat 7.0.
3010 Added step-size for Scan backend handler.
3012 Fixed bug that made the frontend server crash when no attribute
3013 set was specified for scan.
3015 Front-end server automatically switches to original working directory
3016 when installed as an NT service. Previously -w had to be specified to
3019 Added extended attributes for retrieval module (data1), so that data1
3020 records carry d1_readXML/SGML attributes. d1_read also supports
3021 null-data rules ( <tag/>)
3023 On UNIX when POSIX threads are available, a separate library libyazthread
3024 is created. Programmers should link with that library and the yaz library
3025 when using threads. The reason for the split was that some applications
3026 on Linux, such as Apache, doesn't work well when using shared objects that
3029 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3030 (or any frontend server) in SSL mode by specifying ssl: followed by
3031 address. Only tested on UNIX.
3033 Added feature for CCL module. Virtual structure s=al or s=ol generates
3034 and-list and or-list respectively instead of phrase search.
3038 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3039 log_mask_str. This was done to avoid name conflicts with other libraries
3040 (such as other PHP extensions).
3042 Added raw OID member for preferred record syntax (request_format_raw)
3043 and returned record syntax (output_format_raw) for backend fetch method.
3045 Config file yaz-config now accepts options so that it returns specific
3046 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3048 Shared library support for UNIX using GNU libtool.
3050 * Modified backend interface. Request/Response struct's replaced by
3051 one read/write C struct. For example bend_fetchrequest and
3052 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3053 Every handler - even search has to be registered in bend_init
3054 handler. This means that the YAZ library no longer refers to
3055 external functions and it makes it possible to make the whole
3056 thing a single DLL/SO.
3058 Added Segment handler for backend server.
3060 Added Zmbol/Zebra administrative functions to YAZ client.
3062 Threaded frontend server on UNIX (when POSIX Threads are available).
3063 Starting the server with option -T enables multi-threading.
3067 Added configure option --enable-comp/disable-comp to control use
3068 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3069 located in sub directory asn.
3071 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3072 in ${exec_prefix}/bin along with the other programs yaz-client and
3075 GNU automake used to maintain makefiles.
3077 Added several OID's.
3079 Changed retrieval module so that we can load records with no abstract
3080 syntax defined. Tagpaths in these records are fully composed of string
3083 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3087 On UNIX, the generated makefile now supports a proper 'make install'.
3088 The prefix can be set via GNU configure to set the install location
3089 (default is /usr/local).
3091 * YAZ programs client and ztest were renamed to yaz-client and
3092 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3093 locations, such as /usr/bin,/usr/local/bin,etc.
3095 * YAZ Header files were moved from include to include/yaz. YAZ Header
3096 files are referred to as include <yaz/log.h> rather than <log.h>.
3097 The YAZ include path (-I ..) is therefore the same as before. Programmers
3098 should update their #include statements or use -Ipath/include/yaz
3099 instead. The main motivation for doing this change is that YAZ header files
3100 can be installed in "standard" locations /usr/include,/usr/local/include
3101 without introducing conflicts, since ALL YAZ header files are stored
3102 in subdirectory yaz (under /usr/include for example).
3104 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3105 rather than project/workspace files. We switched because project files
3106 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3109 Changed name of logging function, logf, to yaz_log, to prevent name
3110 clash with some math-log functions. The YAZ header log.h defines logf
3111 to yaz_log (#define) so there should be no incompatibilities by this
3114 Added bend_start/bend_stop handlers for server. These handler are
3115 called on start/stop of server. For windows they are called whenever
3116 a service is started/stopped.
3118 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3119 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3120 in util/yc.tcl. The auto-generated C code structures are, in a few
3121 cases, incompatible with the old decoders. There are differences in the
3122 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3123 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3124 The preprocessor variable ASN_COMPILED is defined when the compiled
3125 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3126 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3127 wish to use the old encoders/decoders you can specify --disable-yc
3130 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3131 version so that it supports both new - and old version of DB Update
3133 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3134 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3135 change. The name parameter can be set to 0 in which no name is specified
3136 for the construction. The macros odr_implicit and odr_explicit sets name
3137 parameter to zero for the construction involved. New macros
3138 odr_implicit_tag and odr_explicit_tag are similar to the others,
3139 except that a name parameter is added. For programmers' that don't use
3140 ODR they probably only need to change the call to z_APDU and z_External.
3142 Added access control facility by interfacing the TCP wrapper library.
3143 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3144 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3145 name of the daemon and enables the access control as specified in
3146 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3148 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3149 den Dool <H.M.vdnDool@kub.nl>.
3151 Added reference ID parameter to most functions in server API - refer
3152 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3154 Changed name of ccl library to libccl.a (was ccl.a).
3156 Fixed bug in decoder for Explain (Category TargetInfo).
3158 Added support for GNU readline in client. Thanks to Jacob Poulsen
3159 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3161 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3162 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3163 IMPLEMENTATION! This change was made to the development version before
3164 the ZIG decided to retract the amendment. If any users MUST be
3165 compatible with the original Update definition, PLEASE CONTACT US, and
3166 we will include a separate definition corresponding to the old Update
3167 ES. Note that because of the change to the ASN.1 of the
3168 TaskPackageRecordStructure we cannot define a single structure that
3169 will support both versions.
3171 * Added const modifier to buffer parameter for some ODR/BER encoding
3172 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3173 completeWAIS, odr_dumpBER.
3175 Fixed bug in client.c which caused a crash when a scanResponse didn't
3176 contain positionOfTerm.
3178 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3179 * will cause an error in a client if a non-YAZ target sends both a
3180 * list of Scan entries and non-surrogate diagnostics.
3182 Retrieval module enhancements. Tag sets may be typed in the reference
3183 to it. From the .abs-file the "tagset" directive takes a third optional
3184 integer type for the tag set referenced. From a .tag-file the "include"
3185 directive takes a third optional type as well. The old "type" directive
3186 in the tag set itself is still recognized but acts as the default type
3189 Backend interface change. Individual Scan terms returned from bend_scan
3190 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3191 in include/backend.h.
3193 Retrieval module enhancements. Multiple tag sets and attribute sets may
3194 be specified in abstract syntax specs. Revised the error/warning for
3195 logging messages reported by the retrieval module when reading the
3198 Object Identifier system (oid_..) changed. The API is backwards
3199 compatible but the oid-routines now allocates new OID's when needed.
3200 Raw OID's may be specified in oid_getvalbyname.
3202 YAZ now uses GNU configure to generate Makefile(s).
3204 * Minor changes in some of the member names of DeleteResultSetRequest and
3205 DeleteResultSetResponse. See include/proto.h.
3207 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3208 and added member 'languages' in TargetInfo (which was missing).
3210 Changed the way attribute sets are handled in the retrieval
3211 module. These are now cached, just like the abstract syntaxes
3214 Changed YAZ so that it links with compiled ASN.1.
3216 Added Explain-schema definitions and mapping routines. The following
3217 Explain categories have been implemented: AttributeDetails,
3218 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3220 Fixed minor bug in Windows version of Server Library.
3222 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3224 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3226 Added EXTERNAL: UNIverse Resource Report (non-standard).
3228 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3229 ENUMERATED and SET OF.
3231 * Added 'const' to some of the char pointer arguments for the
3232 functions, data1_read_node, data1_getelementbytagname,
3233 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3236 Fixed bug in data1_insert_taggeddata - the last_child member of
3237 parent wasn't initialised.
3239 * Changed data1_read_record and data1_read_node so that the supplied
3240 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3241 doesn't refer to any parts of the "SGML"-buffer.
3243 Fixed bug in server library (Windows version of statserv_remove).
3245 * Changed code so that it compiles as C++. The type definition
3246 of Odr_fun which is a member of Odr_arm was changed. The result is,
3247 that an explicit typecast is needed for the fun pointer when
3248 using Odr_arm - as in:
3249 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3251 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3253 Implemented the new structured date and time definition as approved
3254 by the ZIG. Added schemaId element to the specificTag in Espec-1
3255 (also approved at the last ZIG). Thanks to RVDM.
3257 Added some Object identifiers (RVDM).
3259 Changed the Update Extended Service (RVDM).
3261 Added command "refid" to client which specifies referenceId for
3262 the following requests.
3264 Implemented extended service handling for server. See ztest.c
3265 for an example as well as backend.h. New handlers are registerd
3266 in the Init handler.
3268 * Changed interface for sort in server.
3270 Added new members to statserv_options_block. It allows a server
3271 to read options from another source than just the command line. Thanks
3272 to Charles Woodfield.
3274 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3275 renamed to zboolean. Some C++ compilers complained about the name.
3277 Minor changes to gils.abs. Added index 's' (sort) on title
3278 and date/time-last-modified.
3280 --- 1.4pl2 1998/1/30
3282 Fixed bug in server library regarding inetd mode (-i). This bug
3283 was introduced by release 1.4.
3285 --- 1.4pl1 1998/1/29
3287 Added sort facility in client and backend server interface.
3289 Fixed problem with dependencies in Makefile(s).
3291 Fixed bugs for encoders/decoders of extended services and
3294 Implemented sub-tree feature for schemas. Sub-trees are
3295 referenced in *.abs-files. See explain.abs for an example
3296 of the use of this feature.
3298 Modified bib1.att; local attributes for ANY didn't include
3299 ANY itself (only affects use of the retrieval module).
3301 Fixed bug in plain SGML reader in function data1_read_node:
3302 tags with prefix "var" was incorrectly interpreted as variants.
3304 Added feature "sub-schemas" to enable references to - and definitions
3305 of - group of elements.
3307 * Removed member parent from type data1_element (in data1.h).
3309 Implemented function odr_nullval() that returns the value of
3312 * Removed member num_children from data1_node (in data1.h).
3314 Made NT service interface part of the server library. The
3315 function statserv_main uses the NT service when required and
3316 calls the statserv_start / statserv_close routines.
3318 Routine zget_SearchRequest and zget_PresentRequest fills
3319 resultSetName/Id member with "default" instead of "Default".
3321 Fixed memory leak in server. Request queue member wasn't freed.
3323 Fixed nmem_exit so that memory is freed.
3327 Revised the CCL parser utility to be thread safe.
3329 Added function, oid_ent_to_oid, to replace the function
3330 oid_getoidbyent, which is not thread safe.
3332 * Added nmem_init and nmem_exit to initialize and release
3333 NMEM resources. Function nmem_init should be called once in the
3334 initial thread before NMEM/ODR is used. statserv.c and client.c
3335 have been changed accordingly. The change was necessary to make
3336 NMEM thread safe. The NMEM memory pool is shared amongst threads
3337 in a process. Unix-based applications will still work fine without
3340 Added NT Services interface for the the Z39.50 (statserv) Server.
3341 Refer to the ztest.c source on the usage.
3343 Windows 95/NT port using MSVC5.0. Project files are included in the
3346 * Defined new 'global' handle for the retrieval (data1) system. The
3347 new handled, data1_handle, describes the state of the data1 system.
3348 This handle is passed as first argument to virtually all
3349 data1 related routines. The functions data1_create and data1_destroy
3350 creates and destroys a data1 handle respectively.
3352 Added ODR encode stream member to all backend request structures
3353 init, search, scan etc. This stream should be used to allocate all
3354 memory used for the response when thread safe operation is needed.
3356 Changed the comstack utility, cs_addstr, to be thread safe. The
3357 returned hostname string returned by the function is now part the
3360 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3361 function. The cs_straddr takes a COMSTACK handle as argument, so this
3362 function must be used after cs_create and before bind/connect.
3363 This function is thread safe.
3365 Moved test server to 'ztest' directory - generic server code still
3366 in 'server' directory.
3368 Made prefix query (pquery.c) utility thread safe.
3370 Added new function modifier YAZ_EXPORT to 'export' public DLL
3371 functions when using windows (see include/yconfig.h).
3373 Added definitions to the OID database (util/oid.c) (RVDM).
3375 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3377 Added call to ccl_rpn_delete in client program.
3379 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3380 release of RPN structure.
3382 Added support for C++, headers uses extern "C" for public definitions.
3383 With input from RVDM.
3385 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3386 Thanks to Ronald van der Meer (RVDM).
3388 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3390 Added support for private extensions to the OID database
3391 (oid_setprivateoids()). Thanks to RVDM.
3393 Added optional, physical ANY (key replication)
3395 Fixed null-reference problem in GRS-1 output filter.
3397 Proximity operator added to Prefix Query Format (PQF).
3399 In test client command "base" accepts multiple databases.
3401 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3405 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3407 Smallish bug-fixes in the new encoders/decoders (explain).
3409 Bug fixed in DeleteRequest.
3411 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3413 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3415 Added SOIF syntax (using private OID for now) to retrieval module and client.
3417 Added Update extended service.
3419 Added SearchResult-1 additional info structure.
3421 Added optional CCL (ISO8777) interpreter as separate module. Available
3424 --- 1.2 1996/6/10 (1st anniversary release)
3426 Added Summary record syntax. Lightly tested.
3428 Added OPAC record syntax. Untested.
3430 Added ResourceReport service encoders/decoders. Untested.
3432 Fixed bug in z_Unit - wrong tagging on unitSystem.
3434 Fixed bug in the DiagRecs decoder.
3436 Added options for max PDU size and session timeout to frontend-server.
3438 Added documentation of query-language parsers and other supporting utilities.
3440 [frontend-server] Added Attribute set to the bend_scanrequest API.
3442 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3443 surrogate diagnostics were generated.
3445 [retrieval] Allow multiple local values for attribute.
3447 [retrieval] Allow multiple attributes per element in .abs files. index type.
3449 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3451 --- 1.1pl2 1996/4/10
3453 Minor changes, mostly specific to Zebra's requirements (retrieval)
3457 Repaired bug in frontend server when running multiple listening
3458 endpoints in dynamic mode.
3460 z_External() now won't break if a known, ASN.1 value comes encapsulated
3461 in an octet-string. The value will pass through unmodified in an Odr_oct.
3463 Added a bit of code to the demo client to decode & display
3464 ASN.1-structured records represented in the octet-aligned branch of
3465 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3467 Added z_ext_getentbyref() to the ASN module. Doc updated.
3469 * Completed the SCAN definition in the ASN module. This may break SCAN
3470 code based on older YAZ-versions at compile-time. The fix is easy -
3473 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3474 under the SCAN definition. Remember to initialize this, server-people.
3476 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3477 that this does not extend to ODR and ASN.
3479 Comstack allows insertion of established socket (primarily for
3480 inetd-operation of servers). Doc updated.
3482 Front-end server can now start from the inetd in TCP mode. Doc
3485 --- 1.0pl4 1996/1/24
3489 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3490 the rank and record number.
3492 Adjustments to the frontend server.
3494 Fixed diagnostic BER dumper. It ignored the file argument.
3498 Various changes to retrieval module.
3500 Changed the union discriminators of the protocol files from enums to
3501 ints paired with #defines.
3503 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3506 *Changed operator in the RPN structure to 'roperator', again to avoid a
3509 Fixed problems in Explain decoders/encoders.
3511 --- 1.0pl2 1995/12/6
3513 Memory bug in log module fixed.
3515 --- 1.0pl1 1995/12/5
3517 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3519 Bug in Explain DatabaseInfo module fixed.
3521 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3525 The shift to v1.0 signals that we now consider the *core* functionality
3526 of YAZ reasonably stable (the core being more or less equivalent to
3527 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3528 tested (Explain not at all - though that will happen soonish).
3530 Minor changes to code to support Windows port.
3532 Various minor changes after we're getting to use GRS-1 & co. more.
3534 Added Espec-1 format.
3536 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3537 of the protocol and it cannot be selected when encoding (maps into 'string'
3538 when decoding). Needed to talk to some servers.
3540 Demo client can request simple element set names.
3542 Added Diagnostic Format encoders/decoders.
3544 Added simple Close handling to frontend server (no hooks for resource
3545 reporting yet), and demonstration client.
3547 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3549 --- 1.0b3 1995/08/24
3551 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3552 handled incorrectly when records were requested in the searchResponse. This
3553 will only affect you if you use the frontend-server.
3555 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3556 Test-client will ask for and print GRS1. Ztest will return dummy records
3559 Added Explain encoders/decoders to the service-level API. Untested.
3561 Added Extended Services: Item Order encoders and decoders to the Service-
3562 level API. Untested. We could use a recent copy of the pertinent bits
3563 of the ILL protocol to add those bits.
3565 Added diagnostic format 1 encoders/decoders to the service-level API.
3568 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3569 odr_cons.c, which causes a more correct output.
3571 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3572 was always set to 0 when no records were requested in the searchRequest.
3574 * Added better external-handling. This shouldn't harm old code that
3575 *encodes* externals. It can break code that looks for a
3576 'single-ASN1-type' representation, since those types that are known
3577 are now decoded immediately. Look at the SUTRS sample code in
3578 seshigh.c and client.c. Documentation updated.
3580 Handling of structured records in bend_fetchresponse. Length -1 marks
3581 structured record, type is deduced from format field.
3583 --- 1.0b2 1995/06/27
3584 Fairly quick maintenance release to add SUTRS support.
3586 Fixed handling of SUTRS records in the demonstration client.
3588 * Added format field to the bend_fetchrequest and bend_fetchresponce
3589 structures of the backend API (frontend server). When the record is
3590 returned, the value of the format field is mapped to an OID. The
3591 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3592 of the record. The special value VAL_NONE in the bend_request means
3593 that no specific format was requested by the client. Documentation
3594 updated accordingly. Test server (ztest) will return a fixed dummy
3595 SUTRS record if your client requests SUTRS.
3597 Documentation updated accordingly.
3599 You can now set external libraries and RANLIB support in the top-level
3603 First public release.
