1 New utility z_get_HTTP_Response_details - an extended version of
4 New utility yaz_url_get_error which returns error message of last
5 failed yaz_url_exec call.
7 yaz-url and url functions: allow max HTTP redirects to be controlled.
9 New functions yaz_file_glob2, yaz_xml_include_glob.
10 These functions takes a flags parameter, which, for now only controls
11 whether to fail inclusion of a non-existing file (without glob
12 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
16 For MARC XML parsing, allow record without leader. A fake/default leader
17 is inserted and a warning is tagged with the record.
19 ICU: fix leak in in icu_iter_get_org_info.
23 ICU: fix bug in icu_iter_get_org_info (un-init variable).
27 Implement z_HTTP_header_remove.
31 ICU: Disallow 0 ptrs for some ICU string utilities.
33 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
34 returns original tokens (before normalization).
36 CCL: avoid z39.58/regex truncation when not needed. Apply only the
37 conversion of those masks, when absolutely necessary.
39 CCL: configurable masking character - @mask. Default masking character
42 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
43 full response anyway, so a Transfer-Encoding header will obstruct the
48 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
49 picking a socket. Problem is that some systems has IPV6 support, but
50 we can't create sockets for them, so we pick AF_UNSPEC first.
52 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
53 use content_len to determine resulting Content-Length in HTTP response
54 and NOT Content-Length supplied in headers by user.
56 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
57 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
59 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
62 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
63 with big endian and unsigned char (by default).
67 Fix yaz-client connect (crash in 4.2.55).
71 Fix proxy/host problem for ZOOM that could occur if unix sockets
74 New Debian package libyaz4-dbg.
76 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
77 differently in tcpip_close.
81 Windows installer of YAZ includes YAZ4J as a component.
83 CQL: allow "extra terms" again, by default. Thus, the CQL parser
84 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
85 and earlier. CQL parser may operate in strict mode where queries
86 not conforming to the standard BNF are rejected (syntax error).
87 Whether the CQL parser operates in strict mode is controlled with
88 cql_parser_strict . Strict mode enabled with option -S for utilities
89 cql2pqf and cql2xcql .
91 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
95 New charset, MARC-8c, which is like MARC-8 but allows control characters
96 0x01 through 0x1F, except ESC to be passed through verbatim.
98 Fix a problem with duplicate sub field character in MARC output. Problem
99 happened only when output was MARC-8 encoded.
101 --- 4.2.52 2013/04/03
103 yaz-ztest: Use hash for fake hit count. Before, random number was used.
104 This is problematic for unit tests using yaz-ztest. This patch also makes
105 a hash for CQL queries. For RPN, any term with a leading digit will be
106 treated as pseudu hit count (to force any particular hit count by a client).
108 yaz-ztest: return unique MARC dummy records. Beyond record offset
109 24, the author surname is patched with offset to make all records
112 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
113 on system wide default (/proc/sys/net/ipv6/bindv6only).
114 @4 binds to IPV4 only. @6 binds to IPV6 only.
116 Update CQL API documentation a bit
118 CQL: don't accept extra terms for queries. Makes the CQL parser
119 stricly conformant to the standard.
121 --- 4.2.51 2013/02/12
123 GFS: scan handler gets extra_args from request and may return extra
124 response data . That's for SRU only.
126 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
128 --- 4.2.50 2013/01/30
130 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
132 OPACXML: sync spelling of availabilityDate in XML to that of Schema
133 opaxxml.xsd. The schema had the correct spelling of this member always.
134 The ASN.1 was mis-spelled and still is (API change) - we are
135 not changing this. However, the OPAC to XML conversion had yet
138 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
141 New function, z_ext_record_oid_nmem, which is similar to
142 z_ext_record_oid but takes NMEM rather than ODR
144 --- 4.2.49 2013/01/18
146 ICU: New conversion element 'join' which joins tokens into one
147 with a custom character given by rule attribute.
149 --- 4.2.48 2013/01/10
151 New GFS search member: present_number. This is a hint to the
152 search handler how many records are going to be fetched immediately
153 following search. There's no guarantee that it's going to be the case,
154 since it depends on hit count (for Z39.50 piggyback) and whether errors
157 Make a few functions static (private). The functions getbyte_stream,
158 ungetbyte_stream and yaz_gets are now private. They were never declared
161 yaz-marcdump: exit(5) for serious decoding errors
163 ISO2709 decoding: be more picky WRT header
165 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
166 was only used as to indicate that next-result-set-position should be
168 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
169 Based on patch from Ashley Sanders.
171 Make some functions static/private in PQF parsing. Those functions were
172 never declared in a public header and so should not be in use by
173 applications based on YAZ.
175 --- 4.2.47 2012/11/23
177 ZOOM: special options to control APDU logging.
178 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
179 logging of APDUs until "saveAPDU" option is set again. If logging is
180 already enabled the effect is that current APDU buffer is cleared.
181 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
182 logging (default behavior on new connection).
183 The APDUs sent/received can be obtained by using
184 Using ZOOM_connection_option_get(c, "APDU") or
185 ZOOM_connection_option_getl(c, "APDU", &l).
187 GFS: relay implementation_version from backend
188 From 3.0.40 and later, implementation_version from backend was
189 not used in init response at all.
191 --- 4.2.46 2012/11/15
193 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
194 mode at all. Probably never did.
196 Make a new version of ztest.pem that, at least, is not expired.
198 --- 4.2.45 2012/11/13
200 Fix description of CCL directive 'case'.
202 More tight checking of form arguments (yaz_uri_to_array). Makes
203 YAZ better at rejecting big and/or bad POSTs.
205 SRU decoding does not report more than up to 10 invalid arguments.
207 rpn2cql: less quotes in generated terms. Semantics unchanged, but
208 it's prettier this way.
210 --- 4.2.44 2012/10/25
212 New utility yaz_decode_init_diag. Defined in proto.h.
214 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
215 given for unix local socket.
216 The COMSTACK string for doing so is:
219 unix:/myfile:tcp:localhost:9999/mybase
220 unix:/myfile:localhost:9999/mybase
221 unix:/myfile:http://fakehost/mybase
223 debian: Use dpkg-buildflags in build process.
225 --- 4.2.43 2012/10/19
227 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
228 global's SRU service uses a recordPosition scheme starting from zero.
229 First record's position should be one
230 according to the standard.
232 --- 4.2.42 2012/10/18
234 Allow more namespaces for SRU. This is to allow, for example, an
235 incorrect namespace returned from server
236 http://services.igi-global.com/sru .
238 Minor fixes for compilation on Windows.
240 --- 4.2.41 2012/10/11
242 daemon: log total number of bad signals from child on stop so that it
243 is more easy to spot problems with child worker processes.
245 retrieval: empty backend name attribute omits element set
246 from being used in retrieval.
248 --- 4.2.40 2012/10/04
250 Implement Solr sort strategy "solr", similar to sru11 sorting.
251 This will implement the correct parameters on Solr requst to do
254 --- 4.2.39 2012/09/28
256 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
259 MARC: Extra/missing indicator handled for MARCXML.
260 The indicator length is given in header and is the same for the
261 whole record. If attributes ind1, ind2 are missing, then content
262 character defaults to blank. Extra indicator attributes (beyond)
263 indicator length are treated as an error.
265 Reformat: delete trailing whitespace
267 --- 4.2.38 2012/09/17
269 MARC: fix non-ASCII characters for leader. This is to ensure we can
270 generate XML in UTF-8.
272 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
273 in one node with structure word.
275 --- 4.2.37 2012/09/04
277 yaz-json-parse: JSON output may be pretty printed by using option
280 Increase default value of max message for Z39.50 Init for GFS, ZOOM
281 and yaz-client. Old value was 1 MB. New value is 64 MB.
283 --- 4.2.36 2012/08/22
285 yaz-client: don't display bogus records from SRU servers. Some SRU servers
286 return more records than given by *maximumRecords*. Skipping those in
289 record_render: simplify buffer return handling and fix at least one bad
290 memory reference, that broke the test_embed_record sometimes.
292 Allow http://user:pass@host notation for yaz_url_exec.
294 zoomsh: allow shell command to be executed. Via the system(3) call.
296 yaz_poll: Allow num_fds == 0
298 yaz-client: fix bad encoding of "itemorder item". The itemorder
299 item <no> - command forgot to use length of encoded Item Request
300 package. Error present since YAZ 3.
302 yaz-ztest: fix bad usage of session handle. Bug was introduced when
303 result sets were saved (271a9c83).
305 SRU recordPacking: guess record packing in response rather than looking
306 at the recordPacking element which, OF COURSE, changed semantics in SRU
309 Decode SRU 2.0 responses. The official namespace for responses, according
310 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
311 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
312 nature.com's server, however, usee namespace
313 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
314 we are now using a glob-expr to match up the namespace. ZOOM C and
315 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
316 I can not find a single real example showing the "real" namespace in
317 the documentation from OASIS. The namespace for requests is different
318 from responses, but this is not added to YAZ yet, when we don't encode
321 --- 4.2.35 2012/06/26
323 zoom/record_render: add support for Base64 decoding fo MARC records
324 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
325 which will decode base64 + ISO2709 marc-8 encoded material from text node
328 --- 4.2.34 2012/06/07
330 Add missing definitions ZOOM_resultset_get_facet_field_by_index
331 and ZOOM_resultset_facets_names.
333 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
336 Change APDU dump printing to avoid long leading blanks. For levels 16
337 or larger the level is shown and the indentation is truncated but
338 recursed with modula 8. This makes it still reasonable easy to read
339 - even for nested BER dumps.
341 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
342 return 0 (incomplete package) in case where the BER package was
343 considered too nested (return value of -2).
345 dumpber: lines of level 15 are not indented further. Two spaces per
346 indentation; indentation 15 or more is indented to a fixed indentation
347 and augmented with a level=<no> indication.
349 zoomsh: increase max size of command+args
351 GFS: No limit in RPN buf size in CQL to RPN conversion.
353 --- 4.2.33 2012/05/09
355 New function for daemon utility, yaz_daemon_stop .
357 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
359 --- 4.2.32 2012/04/25
361 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
362 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
364 --- 4.2.31 2012/04/23
366 YAZ daemon utility relays SIGUSR1 to child process.
368 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
369 would result in en empty database list - which in turn would result in
370 encoding failure for search.
372 Fix reading beyond string in yaz_sort_spec.
374 --- 4.2.30 2012/04/11
376 Add two new SRU diagnostics:
377 236: Access to specified database denied
378 1015: Init/AC: Maximum number of simultaneous sessions for Userid
380 Document the very useful ZOOM-C option "apdulog".
382 CQL to RPN: term may be passed through verbatim. This is enabled with
383 truncation.cql . The assumption being that the term is already CQL.
385 --- 4.2.29 2012/03/20
387 record_conv: leader spec may be given for marc element.
388 The leader spec is given as attribute leaderspec for element marc.
389 For example to convert a MARC21 record from MARC-8 to UTF-8:
390 <marc inputformat="marc" outputformat="marc"
391 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
393 record_conv: allow user-XSLT params. For example:
394 <xslt stylesheet="MARC21slim2DC.xsl">
395 <param name="myparameter" value="myvalue"/>
396 <param name="otherparameter" value="othervalue"/>
399 record_conv: fix error handling for missing marc charsets.
401 CQL: fix extra terms in wrong order.
403 --- 4.2.28 2012/03/06
405 record_conv: modify new API for conversion types. The conversion types
406 may be passed in new functions yaz_record_conv_configure_t and
407 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
409 Avoid mixed statement/variable declare; fixes compilation with Visual
412 --- 4.2.27 2012/02/28
414 Add non-standard SRU diagnostic: 235: "Database does not exist".
415 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
416 Update SRU to Bib-1 diagnostic maps accordingly.
418 CCL: add two new diagnostics for unsupported masking. The new
419 diagnostics are: "Embedded truncation not supported" and
420 "Single charcacter mask not supported".
422 --- 4.2.26 2012/02/23
424 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
426 --- 4.2.25 2012/01/11
428 Build YAZ for Ubuntu Oneiric.
430 CCL: allow parantheses for proximity operands. For example CCL query
431 (a) % (b) is now allowed.
433 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
434 marked dead, rather then being destroyed. If not, the session memory is
435 being free'd before the search/scan handler is finished. Also destroy
436 'request' memory in request_release rather than in various places,
437 which resulted in leaks from time to time.
439 --- 4.2.24 2011/12/21
441 cql_sortby_to_sortkeys: honor sort prefix.
443 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
444 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
445 The rpn2cql family of functions now always returns quoted CQL terms.
447 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
449 --- 4.2.23 2011/12/15
451 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
452 sequence is treated as one. For example, &&a=b&&&c& is identical to
455 --- 4.2.22 2011/12/05
457 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
458 APDUs for a connection to a WRBUF.
460 --- 4.2.21 2011/11/23
462 Fix cql_sortby_to_sortkeys. Completely broken before.
464 Make CCL's @truncation work again.
466 --- 4.2.20 2011/11/09
468 New ZOOM connection setting: tproxy. It's like proxy, but does not
469 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
470 to set resolved address + port for a connection outside ZOOM itself.
472 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
474 --- 4.2.19 2011/11/07
476 Fix uninitialized variable in Solr spell support (could cause SEGV
477 for SRU response decoding).
479 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
480 back-end's addinfo through into the ZOOM response addinfo.
482 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
483 they are separated by a colon and a space rather than simply
486 --- 4.2.18 2011/10/28
488 Add support for Solr spell-checking/suggestions through ZOOM.
489 If a Solr target has been configured correctly for spelling-checking
490 and suggestions, these will now be returned on the ResultSet option
491 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
493 --- 4.2.17 2011/09/28
495 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
496 with a flag whether to substitute escape sequences or not.
498 --- 4.2.16 2011/09/22
500 Fix nmem_strsplit_escape to substitute escape char properly.
502 New option for zoomsh -e , which makes it abort on first error and
503 return process exit code to indicate success/failure.
505 YAZ options utility supports special option -- which makes all it treat
506 all following arguments as non-options.
508 --- 4.2.15 2011/09/16
510 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
511 searched if absolute filename is given.
513 Fix conv_xslt() error-reporting when stylesheet is not found.
514 (The value of fullpath is meaningless in this situation.)
516 --- 4.2.14 2011/09/07
518 Fix problem in CQL sort node creation: un-initialized memory.
520 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
521 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
522 CQL sortby depending on whether Type-1 or CQL is actually sent to the
525 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
526 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
528 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
529 will make it possible to use both single-character mask (#) and wildcard (?)
530 in CCL . Throw diagnostic for left truncation because that is not supported
533 --- 4.2.13 2011/09/01
535 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
536 cases using escapes (\-sequences) and masking.
538 PQF parse fix: A trailing backslash followed by end-of-string (\0)
539 would result in a read one byte beyond string.
541 rpn2ccl may use Z39.50 masking for terms (t=z).
543 ICU check fix. Don't include library -lCrun on Solaris, unless present.
545 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
546 not --cppflags (which seeems like an error in icu-config).
548 --- 4.2.12 2011/08/27 RPM package only
550 cql2ccl: fix conversion of terms: operator characters were not
553 --- 4.2.11 2011/08/25 RPM package only
555 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
556 CCL parser will map both # and ? to their regular expression
557 quivalents (. and .*).
559 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
560 of reserved CQL characters.
562 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
563 is, so that they are passed through.
565 --- 4.2.10 2011/08/24
567 ZOOM SRU mode: more aggressive re-connect.
569 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
570 made available as a utility function, declared in <yaz/logrpn.h>
572 rpn2cql_structure() supports proximity nodes (except that the Type-1
573 proximity node's "exclusion" binary is ignored, as there is no way to
574 express that in CQL). Fixes bug #4564.
578 Fix SEGV that could occur if set command of zoomsh was given without
579 value (2nd argument).
581 Fix SEGV that could occur if unsupported transport was given for
582 COMSTACK - say https (when SSL was unavailable).
584 Build yaz-url on Windows too.
588 New utility to get web content. Header is url.h. A command line tool
589 yaz-url is part of the distribution and packages.
591 Fixes for SSL COMSTACK (when gnutls is in use).
593 New functions yaz_base64{encode,decode}. Header is base64.h.
597 ZOOM C includes HTTP response buffer as additional info if it fails
598 to decode the SRU response.
600 Make wrbuf_json_puts available.
604 zoom: throw diagnostic for invalid value for option "sru". Before a
605 bad SRU request was sent.
607 Adding new utility wrbuf_vp_puts.
609 Add cclxmlconfig.obj to win/makefile. It was missing completely.
613 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
614 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
615 redirect was used at the same time.
617 MARC line mode decoding: be less picky about length given - first
618 5 digits of header that is.
620 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
622 Changes to decoding of SRU records: a record with recordPacking=xml is
623 modified with a new root element <yaz_record> if the recordData contains
624 multiple children elements. This is to make the record XML parseable
627 RPN to Solr conversion: encode special characters.
629 Generic Frontend Server: fix uinitialized member, stepSize.
633 Fix a bug in SRU decoding of records.. The database records stored
634 had un-initialized memory, but it would only be seen with yaz_record_render
635 and type_spec="ext" .
637 Fix a bug in ccl_qual_dup introduced in 4.2.3.
641 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
645 Add new utilities to convert from CQL to CCL . These utilities have
646 prefix cql_to_ccl defined in cql.h.
648 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
649 lead to memory heap corruptions when ICU utilities were in use.
653 Make compilation work without Libxml2.
655 yaz-client: remove redundant blanks in display of searchResult-1 term
660 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
661 resulting CQL node (tree) in a new node CQL_NODE_SORT.
663 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
664 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
665 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
666 Note that the CQL sortby spec is only converted when the GFS is already
667 converting from CQL to RPN (cql2rpn element).
669 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
670 specify whether to collapse delimitors or not. The existing nmem_strsplit
671 do collapse (collapse parameter = 1).
673 Windows installer: For NSIS, set InstallDir depending on x86/x64.
675 Rename internal func yaz_use_attribute_create. While non-static, this
676 function is not declared in a public header.
680 Add -lCrun when linking with ICU on Solaris.
682 More quicks character set conversions for OPAC records.
686 fix problem with record_render: records were converted (character set
687 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
691 SRU: add methods for handling DADS SRU-proxy facets.
693 Separate OPAC record character set for ZOOM_record. yaz_record_render
694 allows a character set given as charset=from/opacfrom,to where 'from' is
695 the character set of a bibliographic record, 'opacfrom' is character set
696 of OPAC record and 'to' is the target character set.
700 yaz-client: show may XML format records. Command show followed by 'format'
701 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
704 src/stemmer.c: Avoid using unnamed union. It is not supported by some
707 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
710 Update yaz.spec to operate on both SLES11 / Centos 5.5.
712 RPM: Release includes 'indexdata' name. Use indexdata in release name so
713 this package can be distinguished from other vendors.
715 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
716 as determined by configure
718 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
720 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
721 returns no error and no record, the present request is considered
722 partial (only a subset of the records could be returned by backend), and
723 so it is appropriate to set Present Status to partial-4.
727 Move yaz-config man pages to section 1.
729 More documentation about Solr.
731 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
732 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
733 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
734 peers on some Linux systems. However, in general that does not work
735 so YAZ can not rely on that to work. Debian changed behavior in this
736 respect from Debian lenny to Debian squeeze (still testing as of Oct
738 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
740 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
744 Fix yaz-config output: echo_source not set correctly by configure.
748 Solr Web Service support for yaz-client and ZOOM.
750 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
752 --- 4.0.12 2010/08/17
754 Z39.50 facet support. Facet specifications are passed for search in
755 other-information with ASN.1 as defined in facet.asn and OID
756 .10.1000.81.5 . Facets are expressed as an Attribute list as known
757 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
758 3 is limit (number of entries to get in response). yaz-ztest returns
759 dummy facets if a client asks for them.
761 --- 4.0.11 2010/07/09
763 CCL fixes: bug 2895 and bug 3539.
765 GR1-display: add comma in display - was removed by mistake in
768 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
770 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
772 --- 4.0.10 2010/06/18
774 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
775 result set from a connection. The result set will be on its own
776 thereafter; no operations on it will perform retrievals from a target.
777 Only cached copies are returned.
779 ZOOM C:fix case for HTTP servers responding with Connection:close.
780 Ensure that if there is a current task it is resumed (like fetching
781 more records in a result set) . Bug #3484.
783 PQF parser: use odr_atoi for Odr_int (not atoi)
785 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
786 values that contain any non-digits are treated as string attributes
787 (previously decoding only checked for leading character ([0-9]). PQF
788 encoding: attribute string values are not surrounded by double-quotes.
792 New utility for managing threads - thread_create.h.
794 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
795 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
796 but YAZ' implementation do.
798 Fixes for yaz_cond-functions on Windows 7.
800 DLL export more symbols.
802 zoomsh: show record do NOT render opac.
804 Remove *.la files from Debian and RPM packages.
808 Debian package libyaz-dev depends on libgnutls-dev again (was
809 removed in YAZ 4.0.6, but due to Libtool it is still needed
810 even though yaz-config do not list libgnutls libs).
812 ZOOM: Use only one WRBUF for returning string results for
813 ZOOM_resultset. Reduces memory usage for ZOOM in general.
815 ZOOM: ZOOM_connection do not use a shared pointer to
816 ZOOM_resultset after ZOOM_resultset is destructed by
817 user. Reverts to YAZ 4.0.4 behavior.
821 record-conv: fix problem with at least one XSL conversion -
822 due to probably incorrect usage of XML XSL documents.
826 Fix yaz-config for static mode and the use of SSL (gnutls).
830 Forward decl timeval struct in mutex.h and gettimeofday.h.
832 yaz-config: fix 'static' mode linking.
836 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
837 are wrappers for pthreads or Windows. For Windows these are put in
838 a separate DLL: yaz_cond4.
840 libyaz.la (whole source) is compiled with thread. If thread support
841 is enabled enabled, all source of YAZ is compiled with treading support.
842 This allows core utilities such as yaz_log to use thread facilities.
843 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
844 thread utilities. This commit moves mutex utilities (mutex.c) from
845 libyaz_server.la to libyaz.la.
847 yaz-json-parse displays leading text until error.
851 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
852 patch from Giannis Kosmas.
854 SRU: no longer URL encode SRU database. The URL for an SRU server is
855 a URL and such is alreeady encoded - at least when given with leading
856 http:// or https://. This reverts behavior to YAZ 3.0.50.
858 Support for new MARC XML notation TurboMARC which like MARCXML is a
859 complete representation of MARC/ISO2709.. This one, however, is more
860 compact and allows for faster processing with XSLT. TurboMARC can be
861 used in the marcdisp.h API, from the yaz-marcdump utility and from
864 yaz-ztest can be configured - via the database - to perform certain
865 delays when it performs operations search, present and single record
866 fetch. This allows testers to make yaz-ztest act as a real or even slow
867 Z39.50 server. Refer to the yaz-ztest man pages for details.
871 wrbuf_destroy allows NULL WRBUF passed to it.
873 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
875 Add ZOOM_connection_close.
877 No fixed size buffers for ZOOM shell - bug #3257.
879 tstodr: make it work on s390 platform.
881 New icu iterator-functions. The new icu_iter-functions makes it possible
882 to use ICU chains from many threads.
884 yaz-client: better syntax check for show command.
888 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
891 New simple local-file XML include facility which allows file glob-patterns.
892 Refer to yaz/xml_include.h.
894 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
897 ZOOM_record_get supports new parameter "format" which makes it format XML
900 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
901 JSONText in ECMA-262) is JSONValue, not JSONObject.
905 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
906 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
908 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
909 POSIX/Unix builds .so with major version 4.
911 Remove old LOG_-defines from log.h. They have been obsolete and
912 undefined by default for the last 5 years.
914 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
916 GFS: Remove socket (int *fd) from search_rr handler. The socket
917 descriptor ptr is a facility that allowed a search handler to supply
918 a socket which would serve as a callback - when search was complete.
919 This facility has now been in use for years.
921 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
922 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
923 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
924 returns 'const char *' rather than 'char *. The returned string is
925 read-only and should not be modified by applications. COMSTACK cs_close is
926 now a void function - it no longer returns int. No applications check for
927 the value and the implementations has always returned 0.
929 ZOOM: use size_t for scan hit counts and str size. Functions
930 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
931 occ (hit count) and len (string length) are now of type size_t pointer
932 rather than int pointer. This is to be able to represent large hit counts
933 and to also just to use the proper type for string length (strlen result).
935 New JSON parser. Refer to include/yaz/json.h .
937 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
938 Used to be int in some cases. Many wrbuf_-functions used to return an int
939 indicating some length.. These return values were never used. And so they
942 ODR: odr_malloc, odr_total now takes size_t for size.
944 clone_z_type: fix leak; occurred for encoding failures.
946 --- 3.0.52 2009/12/03
948 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
949 bug was introduced in 3.0.51.
951 --- 3.0.51 2009/12/02
953 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
955 tcpip comstack: fix leak for getaddrinfo.
957 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
958 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
959 Decoding of SRU "path" database is performed by private function
960 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
961 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
963 yaz-client: honor base command for SRU. Change when database setting
964 is applied for SRU and ensure it is kept when a connection is reset.
965 Change also the way errors are displayed or SRU (decoding of packages).
967 --- 3.0.50 2009/11/02
969 Add support for extra request / response data for SRU codecs and GFS.
970 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
971 for extra data response buffer and length. For the GFS, both request
972 and response data (XML) is carried in extra_args and extra_response_data
973 for the search handler. Patch by Ko van der Sloot.
975 ZOOM: For queries that cannot be converted to the specified rpnCharset,
976 ZOOM now returns a diagnostic on the client-side ('invalid query' /
977 10010). This fixes bug #2113.
979 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
980 cmdfile included a 'quit' command that would result in a memory violation.
982 --- 3.0.49 2009/10/01
984 Make a number of functions defined in xmlquery.c static. These have
985 never been declared in a public header file (yaz/xmlquery.h) and was
986 made public by mistake.
988 Improve speed of character conversions (iconv utilities). This makes
989 conversions from MARC-8 faster.
991 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
992 unless type desired is "raw". This will prevent type "xml" from
993 returning ISO2709 .. Which obviously can not be XML parsed.
995 Fix memory leak in ZOOM that would occur if option apdulog was used
996 on a re-used connection.
998 Frontend server logs HTTP requests.
1000 Frontend server now sends Z39.50 close when it times out (sesssion has
1001 been idle for too long). Versions 2.0.30 and earlier also sent close.
1002 But due to a mistake this was disabled in all versions after that, i.e.
1003 the server would just close the socket immediately.
1005 yaz-client emits a better message when receiving an unrecognised
1006 userInformationField.
1008 Skip zero-length subfields when decoding ISO2709. This rare case happens
1009 if a record has two FS characters in a sequence. Without this patch
1010 there would be a reference beyond char array in using_code_len fragments
1013 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1015 --- 3.0.48 2009/08/28
1017 The show command offered by the zoomsh command now takes a 3d optional
1018 parameter type which is what is passed to ZOOM_record. If the type
1019 argument is omitted, "render" is used.
1021 RPN to CQL conv may use USE string attributes (bug #2978).
1023 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1025 --- 3.0.47 2009/07/08
1027 Function yaz_xml2query allows a diagnostic element in the PQF XML
1028 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1029 code and additional info respectively.
1031 The BER BOOLEAN is now the integral type Odr_bool which still happens
1032 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1033 typedef'd to Odr_int. This is still an integral 'int', but it may be
1034 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1035 ASN-1 compiler as well as programs has been updated to use the new types.
1037 --- 3.0.46 2009/06/08
1039 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1040 only the bibliographic record was rendered. For type=opac, an OPAC
1041 record is only returned if it is present.
1043 iconv: small fix for encoding of advancegreek.
1045 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1047 yaz-client: option auto_reconnect=on really reconnects.
1049 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1051 server: avoid null ptr ref for for yaz_poll errors.
1053 build: fix RPM build for RHEL 5.3.
1055 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1057 --- 3.0.45 2009/03/31
1059 Fixed bug #2709: TCP connect returns Invalid argument.
1061 Fixed compilation for mingw.
1063 Honor charset for raw records (ZOOM_record_get).
1065 Fixed use of errno for threaded mode that was seen on Solaris 10.
1067 Fixed argument passing with blanks in value for Windows Service.
1069 Disable YAZ' own log rotate by default (no 1 GB limit).
1070 The variable l_max_size which specifies the log file limit is set to 0
1071 (DISABLED): This is due to the fact that YAZ is most often deployed using
1072 logrotate. Also YAZ can not perform log rotate because of unsufficient
1073 permissions (setuid).
1075 --- 3.0.44 2009/02/17
1077 List supported encodings in man page for yaz-iconv.
1079 Fixed missing SSL libs for --libs output
1081 Re-established OID record syntax application-xml. Nobody should use it
1082 but we don't want to change soname because of this symbol being absent.
1084 --- 3.0.42 2009/02/02
1086 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1088 Added member named_result_sets for init handler struct for the GFS. This
1089 allows a server to disable named result sets.
1091 Removed OID record syntax application-xml.
1093 Added support for rule-based transliterator for ICU wrapper of YAZ.
1095 Fixed bug #1902: yaz-icu XML output.
1097 Make YAZ checks Emacs friendly.
1099 BITSTRING value shows value. Bug #2346.
1101 ISO2709 decoding: skip control characters from indicator data.
1103 Omit sort key by default in yaz-icu's output.
1105 Allow combined single char options (again) for YAZ' options function.
1107 Utility yaz-marcdump got option to display YAZ version (-V).
1109 Allow YAZ to use ICU 3.4.
1111 Added new ICU test case which illustrates removal of diacritics.
1113 --- 3.0.41 2008/12/29
1115 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1117 --- 3.0.40 2008/12/29
1119 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1122 Fixed bug #2352: yaz-marcdump crashes for certain record.
1124 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1126 Added support for Danmarc2 to UTF-8 conversion.
1128 Added support for ISO5426 to UTF-8 conversion.
1130 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1131 implementation version.
1133 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1135 --- 3.0.38 2008/11/10
1137 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1138 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1140 ZOOM C now interprets databaseName option for ZOOM connection as path
1143 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1145 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1147 Dummy Libxml2 types no longer defined in headers of YAZ'.
1149 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1152 --- 3.0.36 2008/09/26
1154 Various ODR chapter fixes.
1156 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1158 Added missing source for Windows compilation, mutex.c.
1160 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1162 For SRU connections in ZOOM all records up to "count" are now fetched.
1164 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1165 in Windows due to bad error handling for Libxml2.
1167 Added facility for sending arbitrary records (ASN.1 any) using
1168 ZOOM C's Extended service update. Patch by Sam Reynolds.
1170 New options for ZOOM C's connection, logapdu which makes ZOOM log
1173 --- 3.0.34 2008/06/18
1175 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1177 --- 3.0.32 2008/06/12
1179 Fixed memory violation that could occur when decoding UTF-8. This bug
1180 was only present in 3.0.30 of YAZ.
1182 --- 3.0.30 2008/06/06
1184 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1185 GNU TLS is used by default (if found).
1187 yaz-ztest returns OPAC records if a client asks for OPAC.
1189 Improved speed of MARC-8 encoding.
1191 Added support for lossy and loss-less MARC-8 encoding.
1193 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1195 Added new Windows Service wrapper (sc).
1197 yaz-client's itemorder command may now send a file.
1199 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1201 Added new function yaz_log_xml_errors.
1203 Allow (but warn) unknown XML attributes in MARCXML parsing.
1205 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1207 The UTF-8 to MARC-8 conversion now uses a different set of characters
1208 for Greek symbols. Bug #2120.
1210 --- 3.0.26 2008/02/21
1212 Added yaz_daemon (daemon.h).
1214 Fixed bug #2068: pkg-config trouble
1216 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1218 --- 3.0.24 2008/01/28
1220 Document --with-xml2 option.
1222 Added OPAC XML XSD (etc/opacxml.xsd).
1224 Allow glob mask for name attribute in retrieval element for the
1225 generic frontend server's retrieval facility.
1227 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1228 except POLLIN/POLLOUT.
1230 Fixed error handling in cs_listen. Bug #2037.
1232 --- 3.0.22 2008/01/20
1234 Fixed version in yaz/yaz-version.h.
1236 Fixed bug #2027: Crash when closing connection.
1238 Changed configure so that ICU support is only enabled if only ICU
1239 and Libxml2 is available (because the ICU chain is XML based).
1241 --- 3.0.20 2008/01/15
1243 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1244 is built. Only this DLL depends on the ICU runtime.
1246 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1247 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1249 Changed license of CCL module to 'Revised BSD'. After consultation with
1250 remaining members of the original EUROPAGATE consortium, we are re-issuing
1251 the CCL module without a separate license. The software was developed by
1252 Index Data as part of a research project. The special license was included
1253 to help feed usage information back to the project consortium to support
1254 project evaluation. At this time, the project consortium has long-since
1255 disbanded, and the majority of the original principals have retired. At the
1256 same time, we have significantly modified the software during the following
1257 years, to the point where very practically no original code remains. To
1258 simplify re-use of the software, we have contacted those members of the
1259 consortium who could be reached, and agreed to re-issue the module as a
1260 proper part of the YAZ package.
1262 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1264 CQL closer to being version 1.2 compliant. CQL also allows free-form
1265 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1268 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1269 bug could make Extended services handling crash in the ZOOM layer. This
1270 bug was only present in YAZ 3.0.18.
1272 --- 3.0.18 2007/12/19
1274 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1277 yaz-marcdump reads and writes collection wrapped records.
1279 Handle OPAC for record conversion module.
1281 Fixes for ICU wrapper.
1283 Allow ICU libs to be controlled with --with-icu .
1285 --- 3.0.16 2007/11/12
1287 Added yaz_poll which is a wrapper for select/poll. When poll is available
1288 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1289 sockets to be in use.
1291 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1292 functionality through an XML based configuration (ICU chain). This system
1293 is useful for search facilities such as Pazpar2 and Zebra that needs to
1294 perform tokenization of indexed material. The ICU code in a separate
1295 library libyaz3_icu.a.
1297 Added HTTP tunnel facility for COMSTACK, bug #1752.
1298 This is a facility that allows a Web proxy, such as squid, to tunnel
1299 Z39.50 traffic. This facility is "transparent" to must applications
1300 using YAZ. It's enabled by using pseudo transport connect: followed by
1301 the proxy address, followed by command, then follwed by he regular
1302 "virtual" addresss. For example,
1303 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1305 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1307 --- 3.0.14 2007/09/21
1309 Fixed bad memory reference in ZOOM_record - cuased by member not being
1310 initialized. This was a problem only in YAZ 3.0.12.
1312 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1313 fields were not removed.
1315 Changed the way C code is generated from codetables.xml. Made a MARC-8
1316 conversion trie for each characterSet section rather than codeTable.
1317 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1318 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1320 --- 3.0.12 2007/09/12
1322 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1323 from ZOOM_record_error).
1325 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1327 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1329 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1331 Better SRW-to-Bib-1 diagnostic mapping.
1333 ZOOM C and yaz-client announces SRU version 1.2 by default.
1335 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1338 Fixed in yaz_sru_decode to allow other version than 1.1.
1340 --- 3.0.10 2007/08/22
1342 Added support for SRU scan for ZOOM.
1344 Added support for the use of the older versions or Extended Service
1345 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1346 set to the version , 1=first, 2=second, 3=third. The third version is
1347 what ZOOM C has used so far. And that, obviously, is the default.
1349 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1350 therefore in Zebra and in SimpleServer-based applications). The new
1351 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1352 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1353 which is passed into the back-end search callback function.
1355 Added support for HTTP Basic authentication in clients: the SRU/W
1356 codec encodes the username/password elements of the PDU structure
1357 appropriately, and these may be set using the "user" and "password"
1358 options in ZOOM-C applications (the same options that are used for
1359 Z39.50 authentication).
1361 --- 3.0.8 2007/06/25
1363 Fixed bug #1208: SSL appears to be broken in ZOOM.
1365 Fixed bug #1206: Libxml2 include path weirdness.
1367 Added oid_name_to_dotstring.
1369 Allow elementSetName to be specified for ZOOM C record update.
1371 Allow waitAction to be specified for ZOOM C based for Extended Services.
1373 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1374 syntax OID. Bug introduced in YAZ 3 series.
1376 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1378 --- 3.0.6 2007/06/06
1380 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1381 directory. yaz-client now reads commands from file given by option -f
1382 if specified; then tries to read .yazclientrc in current directory.
1383 Failing that, it reads .yazclientrc from user's home directory.
1385 Added support for correlationInfo Note and ID for Record Update via
1388 Added yaz-client command querycharset which specifies character set for
1389 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1390 (termListAndStartPoint).
1392 Charset ISO5428:1984 is an alias for ISO5428-1984.
1394 Implemented a way to perform scan in a result set using Z39.50. This
1395 is achieved by attaching the result set name in the characterInfo
1396 (type InternationalString) of OtherInformation in the Scan Request PDU.
1397 The result set is identified in the otherinformation by the new OID:
1398 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1399 This allows for scan in result set and faceted search . Zebra did some
1400 of this in the APT term using attribute type 8 and value being result
1401 set. Using the OtherInformation approach for this is cleaner and easier
1402 to work with in proxies and the like. This facility can be used in
1403 yaz-client using new command setscan which takes a result set as first
1404 argument, start position (APT) as second.
1406 Changed decoding of SRU XML packed records to deal with servers that
1407 have recordData with XML data with multiple root nodes. Also make
1408 comparison for recordPacking case insensitive. Again, one server
1409 returns "XML" where others return "xml".
1411 For SRU responses allow Content-Type application/xml as well as text/xml.
1413 --- 3.0.4 2007/05/21
1415 Fixed bug in character set conversion of BER strings. Bug introduced
1418 --- 3.0.2 2007/05/08
1420 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1422 For OID class, use oid_class consistently.
1424 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1427 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1428 character set for bibliographic information interchange". By Giannis Kosmas.
1430 Added documentation on new OID API.
1432 --- 3.0.0 2007/05/02
1434 Changes to generic frontend server interface: added new member
1435 'query_charset' for bend_initrequest structure. A backend init handler
1436 should set this member to its native character set for query terms.
1437 When defined, the frontend server logic will announce this character set
1438 to a client if the negotiationModel bit is set by the client. All server
1439 implementors are encouraged to specify this. If a backend server does not
1440 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1442 Added CCL utility to remove terms (stop words) from resulting RPN
1443 tree. This is handled by functions with prefix ccl_stop_words_ .
1445 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1446 terms in RPN queries.
1448 Clean-up the CCL API. Moved some internal structures from ccl.h to
1449 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1450 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1451 This is replaced by ccl_parser_find_str which takes a string instead.
1453 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1454 libyaz.la is the core of YAZ except the generic frontend server and
1455 does not depend on POSIX threads anymore. libyaz_server.la is the
1456 generic frontend server facilities and uses POSIX thread functionality
1457 if available. The libyaz.la no longer depends on POSIX threads because
1458 the number of global structures is limited. NMEM no longer re-uses blocks
1459 between threads ; it simply free's memory immediately but allocates in
1460 "large" chunks as usual. We don't expect any performance penalties
1461 because of this. The yaz_log system is still using a global log_level so
1462 caution must be taken when modifying it with yaz_log_init_.. +
1463 yaz_log_mask_str. This, however, should not cause any trouble because
1464 these functions are called during initialization of application code
1465 anyway. `yaz-config --libs server` returns libs for server applications;
1466 `yaz-config --libs` returns libs for non-server applications.
1468 New OID database - with public definitions in oid_db.h. Removed old OID
1469 database including the head oid.h and definitions such as enum oid_value
1470 and struct oident. The new OID database uses the same string names as
1471 before but the 'protocol' is gone. There are now only two representations
1472 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1473 converts from string to OID; functions with prefix yaz_oid_to_string
1474 converts the other way.
1476 Change to emit_term() in CQL-to-PQF query translation: when a term has
1477 the /regexp relation modifier, do not process it for leading and
1478 trailing "^" and "*", which have quite different meanings in regular
1481 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1482 write handlers no longer carries a 'last' parameter. This will make
1483 yaz_iconv flush "less" characters. A flush is performed by call to
1484 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1486 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1487 removed, because function yaz_query_to_wrbuf does the same.
1489 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1490 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1492 Deprecated MARC utility functions removed.
1494 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1497 Branch split: YAZ_2_1_55_branch
1499 --- 2.1.54 2007/03/16
1501 Fix to ZOOM-C so that transparent reconnection is properly handled on
1502 connections that are in asynchronous mode.
1504 Fixed compilation on OpenBSD 4.0.
1506 Large strings in GRS-1 records are now properly displayed in yaz-client.
1508 Added character conversion support for "advancegreek"; based on patch from
1511 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1512 sequence is met. Before the error was not set so it would be unknown.
1514 Adjust yaz-marcdump MARC reader so that it skips until record separator
1517 --- 2.1.52 2007/03/07
1519 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1520 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1521 fd_set structure used as a bitmask for the FDs to be selected on.
1523 Using ACX_PTHREAD macro to check for POSIX threads.
1525 Fixed have-vsnprintf check.
1527 --- 2.1.50 2007/02/23
1529 Fixes for configure on BSD. Bug #900.
1531 Added snprintf/vsnprintf wrappers for systems that don't have
1532 limits (heavens forbid).
1534 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1535 created before all previous tasks were completed and removed from the
1536 task queue, the new task could be removed by a mistake.
1538 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1540 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1542 Fixed bug #832: Problem with MARC/charset in yaz-client.
1544 Fixed bug #668: save command line history for yaz-client.
1546 Fixed bug #830: pkg-config support.
1548 --- 2.1.48 2007/01/23
1550 Extended ZOOM result set options with two options that may be read by
1551 a client: resultSetStatus and presentStatus with values as specified for
1553 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1555 Fixed bug #827: Using SSL fails on Debian etch.
1557 Fixed bug #826: Weird looking chars for set of MARC records.
1559 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1560 that is treated as an ItemOrder with itemRequest being an XML document
1561 external. The value of "doc" is the content.
1563 Extended the GFS search facility. New member of bend_search_rr
1564 'estimated_hit_count' signals that hits is known to be an estmate
1565 (higher or lower than real hit count). New member 'partial_resultset'
1566 signals that the search was partial (hit count is lower or equal than
1567 real hit count). For Z39.50, the information is stored in resultSetStatus
1568 member of SearchResponse APDU. For SRU, the information is signalled
1569 via SRU diagnostic 59: "Result set created with valid partial results
1572 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1574 --- 2.1.46 2007/01/13
1576 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1578 Added ZOOM_connection_peek_event.
1580 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1581 the following new functions:
1582 ZOOM_event_nonblock, ZOOM_connection_process,
1583 ZOOM_connection_get_{socket,mask,timeout},
1584 ZOOM_connection_fire_event_{timeout,socket}.
1585 The existing blocking event handler, ZOOM_event, is a wrapper for the
1586 + blocking ZOOM_event_sys_{poll,select}.
1588 Implemented function ccl_xml_config which parses XML version of CCL
1589 configuration (bug #798).
1591 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1593 Added timings utility (yaz/timing.h)
1595 --- 2.1.44 2007/01/03
1597 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1600 Fixed bug #779: Rotation of apdu.log fails.
1602 Fixed for character set conversions:
1603 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1604 Honor G1 set in MARC-8 decoding.
1606 --- 2.1.42 2006/12/17
1608 Fixed bug #775: char conversion does not handle Alternative UTF-8
1611 Implemented function yaz_marc_read_line which parses MARC line format
1612 records. There is a wealth of formats out there. So far, this function
1613 reads line records produced by yaz_marc_write_line.
1615 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1616 more generic and easier to remember(!) options: -i format and -o format
1617 which specifies input format and output format respectively - where
1618 format is one of "marc", "marcxml", "line", "marcxchange".
1620 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1621 does not print anything except warnings for records.
1623 For yaz-marcdump, added support for MARC split into files (-s) with a given
1626 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1627 spec, at http://www.loc.gov/standards/sru/record-update/
1628 This has changed the binary layout of the following structs:
1629 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1630 bend_update_rr . Patch by Ko van der Sloot.
1632 Added GFS utility function bend_assoc_is_alive which returns 1 if
1633 association is still alive (client is connected); 0 otherwise (client
1634 closed connection). This allows busy servers to stop working for
1637 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1638 been a separate piece of software. This version of ziffy has been modified
1639 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1641 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1643 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1644 Client code may now interrogate options such as "init_opt_sort" to
1645 find out whether the server claims to support various options.
1647 --- 2.1.40 2006/11/27
1649 Added utilities yaz_{set,get}_esn to set/get element set name from
1652 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1653 of YAZ and has been so since YAZ 2.1.10.
1655 Implemented ZOOM_record_error which returns error information for
1656 record (surrogate diagnostic).
1658 --- 2.1.38 2006/10/31
1660 Updates for SRU Update by Ko van der Sloot:
1661 1. Changed name from "operation" to "action"
1662 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1663 versions in the code, marked as 'backward compatible'.
1664 3. Added diagnostics for SRU Update.
1666 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1668 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1670 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1672 For GFS, fixed problem with SRU diagnostic 'First record position out of
1673 range' being issued for 0 hits.
1675 zoomtst10 part of Windows Build.
1677 --- 2.1.36 2006/10/13
1679 Implemented yaz_filepath_comp which splits a path into file path
1680 components (required by Zebra 2.0.3+).
1682 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1683 BSD inspired license until now so this should not have any real impact on
1684 anybody. See http://www.opensource.org/licenses/bsd-license.php
1686 Fixed bug #687: Missing log lines.
1688 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1691 Fixed bug #689: SRU diagnostics to be added.
1693 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1694 whether a connection is idle (no more work do do).
1696 --- 2.1.34 2006/10/04
1698 Change type of optval from long to int for invocation of setsockopt with
1699 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1701 Added support for specifying the max log file size for the Generic
1702 Frontend Server. The size is given with option -r.
1704 --- 2.1.32 2006/09/21
1706 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1708 --- 2.1.30 2006/09/17
1710 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1713 Fixed bug in Generic Frontend Server that could cause a server to stop
1714 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1716 For the generic frontend server, the maximum record size is used as maximum
1717 size of incoming packages (SRU + Z39.50). The value until was previously
1718 only used in Z39.50 Init negotiation and, later, in a session controlled
1719 sizes of records returned. This is controlled using -k option. It can be
1720 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1722 --- 2.1.28 2006/09/04
1724 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1727 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1729 New option for yaz-marcdump -lpos=value which allows setting a portion
1730 of MARC header to a certain value.
1732 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1734 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1735 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1737 --- 2.1.26 2006/08/15
1739 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1742 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1744 --- 2.1.24 2006/08/08
1746 Fixed MARC ISO2709 encoding routines to deal with character set
1749 Minor changes to GFS logging. Database included in search request log
1752 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1753 cached/multiple records.
1755 Shared libraries are built by default on Unix+configure.
1757 Changed cql2pqf transformation to use a different evaluation order. The
1758 new order is: always, relation, structure, position, truncation, index
1759 and relationModifier. Old order was: always, relation, relationModifier,
1760 structure, index, position, truncation. Note that the the latter ones
1761 override former ones for identical attributes.. The new scheme means that
1762 it is possible to override any existing attribute with a relationModifier.
1763 And also that it is possible to override everything for the index rule
1764 (except the ones listed in relationModifier). No order is perfect but this
1765 one, we believe, covers more real cases.. The "always" should have been
1766 called "default", since the attributes there can be overridden with all
1769 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1770 compilation phase, but also for yaz-config --cflags output. This allows
1771 us to have public headers with Libxml2 stuff in them . It should also,
1772 eventually, make Libxml2 checks redundant in packages using YAZ, such
1775 --- 2.1.22 2006/06/15
1777 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1778 stored in uri, message and details.. Previously diagnostics were stored
1779 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1780 compatibility.. but he's probably the only one affected, so.
1782 Added support for CCL, compiled on the client side, in ZOOM-C. This
1783 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1784 input; the resulting query objects can be used for for searching with
1785 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1787 YAZ' configure searches for OpenSSL by default.
1789 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1790 SL_CTX_use_certificate_file. See
1791 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1792 for more info. Thanks to Ko van der Sloot.
1794 --- 2.1.20 2006/06/02
1796 Bug #600: SRU GET, POST support for yaz-client. Introduced
1797 command 'sru' which selects method SOAP/GET/POST.
1799 Allow missingValueAction to be specified for the sortspec string -
1800 function yaz_sort_spec. By default, the missing value action is null.
1801 Use ! to specify "abort". Use = followed by stringvalue to specify default
1804 Ensured that Present-handler (if defined) is called in GFS before any call to
1805 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1806 searchRetrieve requests.
1808 Documentation for YAZ is now based on the Docbook XML/XSLT using
1809 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1810 is no longer depending on jade/openjade or docbook-to-man scripts.
1811 PDF is no longer part of the distribution - but can optionally be
1812 made using DSSSL/jadetex or FOP.
1814 Added retrieval handling support in Generic Frontend Server to support
1815 conversion between MARC/XML as well as XSLTtransforms. See
1816 etc/yazgfs.xml for an example.
1818 Added Authentication support to Generic Frontend Server in SRU
1819 mode. Authentication using HTTP Basic is supported, as is the use
1820 of 'x-username' and 'x-password' parameters in the request itself.
1822 Added support for a new character set MARC8s identical to MARC8 except
1823 that it converts combined characters to single Unicode characters in the
1824 Latin-1 range (when possible).
1826 --- 2.1.18 2006/04/24
1828 ASN.1 compiler 0.4: generates brief Doxygen file header for
1829 generated .h/.c files.
1831 Utility yaz_iconv now supports conversion to MARC-8.
1833 New facilities for the MARC module. The reading - and writing of
1834 content are separate methods for the yaz_marc_t handle. The following
1835 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1836 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1837 format). Write functions have prefix yaz_marc_write_.. The existing
1838 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1839 available. Removed support for OAI-MARC and simplexml (not the
1840 simplexml from PHP5).
1842 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1843 to be returned for this connection.
1845 --- 2.1.16 2006/03/31
1847 Allow multiple languages and charsets to be specified with
1848 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1849 negcharset iso-8859-1,utf-8
1851 Translation of proximity nodes from CQL into PQF now works.
1853 Moved to automake 1.8, 1.9.
1855 Added function yaz_log_set_handler which allows a log handler to be
1856 installed. This handler will be called for all log messages. Output
1857 to file is also produced; but that can be disabled by passing NULL
1858 fname to yaz_log_init_file.
1860 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1862 For SRW (including GFS), accept application/soap+xml as content-type
1865 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1866 produces NO stylesheet reference even if a default stylesheet is specified
1869 --- 2.1.14 2006/03/14
1871 Updated Windows package to include yazd.dll + yazd.lib for the
1872 Development component.
1874 If the environment variable YAZ_LOG is set, then it is used as a
1875 string indicating the default level of logging to use if not
1876 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1877 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1878 used as before. So, for example, to omit warnings from YAZ logging,
1879 export YAZ_LOG=-warn
1881 cql_transform() now map structure and other attributes before indexes,
1882 so that index-specific structures and other attributes can override
1883 defaults. So now a combination of mapping specifications such as:
1885 index.dc.date = 1=date-modified 4=5
1886 does the right thing.
1888 cql_transform() now also respects the "always" mapping specification,
1889 which establishes an initial set of attributes to be used for all
1890 terms except where overridden by more specific attributes associated
1891 with the index, relation or modifier.
1893 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1894 which mode to use; one of "post", "get" or "soap" (SRW, default).
1896 Fixes for yaz_iconv routines: changed trie-based character set conversions
1897 to use only non-negative values for bit fields due to Sun's C compiler not
1898 supporting negative values.
1900 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1901 sequences where not read correctly. Fix by Rustam Usmanov.
1903 Updated win/makefile to use options, settings which makes things
1904 compile with VS C 2005.
1906 --- 2.1.12 2006/02/01
1908 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1910 In ZOOM socket code, use select instead of poll on MacOSX.
1912 ZOOM-C now support client-side compilation of CQL into RPN that is
1913 sent to the server, enabling CQL to be used against all Z39.50
1914 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1915 ZOOM_query object, and submit it using ZOOM_connection_search().
1916 The CQL-to-RPN translation uses a configuration file, the name of
1917 which must be specified in the Connection's "cqlfile" option.
1919 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1920 function, which takes as its start-term parameter a ZOOM_query object
1921 (which may have had either CQL or RPN set into it).
1924 --- 2.1.10 2005/11/29
1926 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1927 GFS to support this as well. Backend handler, bend_srw_update, does the
1928 update work. Code contributed by Ko van der Sloot.
1930 Allow retrieval of Search Result-1 information in ZOOM by the use of
1931 options that are attached to a result set. ZOOM documentation updated
1934 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1935 UTF-8 conversion. Patch by Raj Patel.
1937 Added option -m to GFS to control formatting of timestamps in log file.
1939 Added 'exit' as synonym for 'quit' in yaz-client
1941 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1942 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1943 for the new members. Patch by Ko van der Sloot.
1945 Added support for SRU POST. It is supported for content-type
1946 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1948 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1949 Instead make the library libyaz.la multi-threaded. Threading as a whole
1950 can still be disabled by configure option --disable-threads. Previosly,
1951 with older GLIBCs there were problems with MT libs under Apache. This
1952 has now been fixed a long time ago.
1954 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1957 CQL module modified to be case insensitive for relations/indexes/operations.
1959 Fixed bug in CQL transform code: incorrect value relationModifieder
1962 Added 'show all' command for yaz-client which retrieves all results
1965 Added new yaz-client, xmles, which takes a (private) OID and
1966 a document to be sent as an extended service request.
1968 Describe new yaz-client commands wait_response and set_auto_wait.
1970 Increase TCP/IP listener backlog from 3 (which I am guessing was
1971 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1972 that the socket will queue as many incoming connections as it's able
1973 to handle ongoing connections. In other words, it will never now
1974 refuse a connection that it would be able to handle merely because
1975 it's not got around to accepting() enough of the pending connections
1976 yet. This is the behaviour anyway under Linux, where the listen()
1977 argument is ignored; but not under BSD and on systems such as
1978 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1979 YAZ-based servers should now be uniform across operating systems in
1982 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1983 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1984 This allows yaz-marcdump to read large MARC batches (>2 GB).
1986 Modified all YAZ source files - except the source which is auto-generated
1987 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1990 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1991 corresponding to the existing *_setl() function. These allow option
1992 values containing arbitrary valuues.
1994 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1995 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1996 except that it returns an indicator of whether or not the sort
1997 criterion was accepted (0 for OK, -1 for invalid).
1999 --- 2.1.8 2005/06/07
2001 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2002 MARC output rather than returning "new" buffer.
2004 yaz-client warns about unknown init options.
2006 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2008 --- 2.1.6 2005/05/24
2010 Added support for SRW sort in Generic Frontend Server. Patch
2011 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2012 sortKeys - or NULL if none is provided.
2014 Fixed bug #307: It was impossible to specify indefinite/no timeout
2015 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2018 Added support for multiple languages and charsets to be specified in
2019 ZOOM. Each charset/language is separated by a blank. If negotiation is
2020 in effect in init-response, Option
2021 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2022 Code based on patch by Vasiliy Osadchuk.
2024 Fixed bug #306: infinite recursion that occurred when calling
2025 yaz_log_level_init as the first call (before other log level or
2028 Fixed bug in scan handling in front end server: if preferred-Position-In-
2029 Response was non-present, a NULL pointer referece was performed.
2031 --- 2.1.4 2005/04/26
2033 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2034 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2035 now defined for all those error codes. So instead of putting 109 in
2036 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2037 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2039 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2042 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2044 Program yaz-client now exits and produces an error message if multiple
2045 Z39.50 servers are specified on the command line (none or one allowed
2048 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2051 --- 2.1.2 2005/03/16
2053 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2055 Fixed bug #272: Preserve spacing for CCL terms.
2057 --- 2.1.0 2005/03/14
2059 Added support for virtual hosts and multiple backend servers for
2060 the YAZ frontend server. The configution is XML based and
2061 support specificition of CQL to RPN mappings and explain information.
2062 See section "Virtual Hosts" in the YAZ manual.
2064 Extended OPAC display utility. OPAC display utility renders
2065 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2066 to supplement yaz_marc_decode_wrbuf.
2068 Fixed a bug in MARC decoder that could caused it to crash for some
2069 invalid MARC records. More diagnostics and warnings where added in
2070 XML output (warnings, etc are stored in comments).
2072 --- 2.0.34 2005/02/08
2074 Fixes for UNIX domain sockets. Bug #261.
2076 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2078 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2079 Added yaz_marc_subfield_str which defines subfield lead string which is
2080 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2081 yaz_marc_endline_str which defines end of fields string used in
2082 YAZ_MARC_LINE format. Default string is newline.
2084 Experimental support for MarcXChange. This format can be produced
2085 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2086 http://www.bs.dk/standards/MarcXchange.xsd
2088 Added yaz-client commands scansize that sets maximum number of
2089 entries to be returned by scan.
2091 --- 2.0.32 2005/01/11
2093 Added support for SRW scan in yaz-client and Generic Frontend Server.
2095 * Added whereInList member to SRW Scan Term.
2097 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2099 Fixed NMEM system to return aligned blocks on the smallest boundaries
2100 that are suitably aligned for all possible types on the particular
2101 architecture YAZ is being built for.
2103 --- 2.0.30 2005/01/04
2105 Fixed numerious warnings that was issued with newer versions of GCC.
2107 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2108 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2111 Make YAZ Generic Frontend Server slightly faster.
2113 Enhance (and reduce) logging for Generic Frontend Server.
2115 Revert YAZ log system so that it flushes every write operation
2116 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2118 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2119 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2120 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2121 will effectively disable old definitions.
2123 --- 2.0.28 2004/11/09
2125 Added yaz_log_time_format which specifies log format using
2128 Added yaz_log_module_level which returns mask for a module. Value
2129 is non-zero mask a if module is enabled; zero if disabled.
2131 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2132 in include/yaz/cql.h.
2134 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2136 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2138 Fixed bug #172: RPM builds does not enable SSL.
2140 Doxyfile.in part of dist. Doxyfile generated by configure.
2142 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2143 are given and the corresponding component does not exist.
2145 Extend CCL documentation in YAZ reference. Describe r=r.
2147 --- 2.0.26 2004/10/01
2149 Fixed MARC->MARCXML conversion to properly deal with
2150 fields, subfields, indicators having non-ASCII characters.
2152 Fixed MARC->MARCXML conversion so that ASCII control characters
2153 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2156 Added YAZ GFS support for conversion from Z39.50 surrogate
2157 diagnostics to SRW surrogate diagnostics.
2159 Bug fix: YAZ GFS did not return schema in explainResponse.
2161 --- 2.0.25 2004/09/30
2163 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2164 now converts recordSchema to elementSetName as well as schema URI.
2166 Fixed bug in COMSTACK that prevented HTTP request packages from being
2169 --- 2.0.24 2004/09/29
2171 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2172 does not require white-space before and after the dash in a range, e.g.
2173 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2176 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2177 due to new GCC removing "redundant" code.
2179 Added yaz-client commands scanpos and scanstep that sets preferred
2180 position and step-size for scan.
2182 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2184 Added CCL utility ccl_qual_buf which parses one or more CCL
2185 spec lines in a buffer.
2187 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2188 of name and value - ignoring empty lines and comments.
2190 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2192 Added odr_get_element_path which returns current element path for an
2193 ODR handle. This utility is useful in error handling or user-defined
2196 Added ODR_PRINT utility odr_set_stream which is is a more generic
2197 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2198 to a write function and pointer to close function. The close function - if
2199 non-NULL - will be called during odr_destroy.
2201 Fixed bug in CCL parser where truncation char was not removed from
2202 right side when truncation=both was in effect.
2204 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2207 --- 2.0.23 2004/08/11
2209 Fix buffer overrun in CQL parser when dealing with proximity (%).
2211 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2212 to UTF-8/UCS conversion is now only based on codetables.xml.
2214 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2216 --- 2.0.22 2004/08/06
2218 Add support for more "commit changes" in ZOOM (uses Extended Services).
2220 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2223 Yet another small fix for configure of SSL.
2225 --- 2.0.21 2004/05/14
2227 Fix SSL libs for configure when --with-openssl=DIR is given.
2229 --- 2.0.20 2004/05/10
2231 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2233 SSL comstack now uses yaz.pem certificate file on server side
2234 by default. Certificate filename can be configured by calling
2235 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2237 Fix bug regarding multiple calls to ZOOM_connection_connect.
2239 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2241 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2242 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2244 ZOOM now allows inspection of X509 peer certificate for verification.
2245 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2247 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2248 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2249 as "modular" but it simplifies things.
2251 Added cs_get_peer_certificate to that returns peer X509 PEM.
2253 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2254 NULL if SSL is unavailable.
2256 Documentation about MARC decoding tools.
2258 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2260 --- 2.0.19 2004/03/30
2262 Rename CHANGELOG to NEWS to follow GNU style packing.
2264 Fix bug with missing initialization of member in init_diagnostics.
2265 This bug affects threaded version of GFS server.
2267 --- 2.0.18 2004/03/20
2269 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2272 Ensure zlib.dll is packed with Windows install.
2274 --- 2.0.17 2004/03/17
2276 Fix encoding of xsd:string to use text instead of CDATA.
2278 Fix endless loop in CQL parser with unbalanced ".
2280 Use a more compact way to store MARC-8 conversion tables.
2282 --- 2.0.16 2004/03/16 Debian only
2284 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2287 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2292 --- 2.0.15 2004/03/01
2294 Another fix for decoding of XML packed records.
2296 --- 2.0.14 2004/02/25
2298 Fixes for Chunked encoding. White space not ignored after length spec.
2300 Update NS and use default NS for SRW diagnostic elements.
2302 --- 2.0.13 2004/02/23
2304 Implement ZOOM_resultset_cache_reset which resets record cache.
2306 Implement ZOOM_resultset_sort which sorts a result set.
2308 Implement chunked HTTP transfer.
2310 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2312 --- 2.0.12 2004/02/16
2314 Added member 'schema' to bend_explain_rr structure so that backend
2315 can specify explain record identifier. Defaults to Zeerex 2.0.
2317 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2319 --- 2.0.11 2004/02/16
2321 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2324 Added init command for yaz-client which sends "extra" init request.
2326 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2327 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2329 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2331 Make ZOOM error code for "invalid query".
2333 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2335 --- 2.0.10 2004/02/05
2337 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2340 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2342 Added option -p <file> to make Generic Frontend Server to write PID file.
2344 Added option -D to put Generic Frontend Server in background on its own.
2346 Make ZOOM C recognize option "password". If unset, "pass" is used
2347 (for backwards compatibility).
2349 Fixed a bug in Generic Frontend Server that could make it crash if a
2350 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2353 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2354 Must be issued before open, in order to be in effect.
2356 --- 2.0.9-6 2004/01/12 Debian/Windows
2358 Make the SRU server more picky WRT unknown params, etc.
2360 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2362 New YAZ client command, options, that sets Z39.50 options.
2364 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2365 options from a string of tokens (one token for each option bit).
2367 Update SRW diagnostic code messages.
2369 --- 2.0.9-5 2004/01/07 Debian/Windows
2371 Handle user defined stylesheet for SRW/SRU.
2373 --- 2.0.9-4 2004/01/06 Debian/Windows
2375 Fix bug in decoding of Content-Length.
2377 --- 2.0.9-3 2004/01/06 Debian/Windows
2379 Fix a bug with decoding of XML packed records.
2381 --- 2.0.9-2 2004/01/05 Debian only
2383 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2385 Fix bug in SRW/SRU diagnostics decoding.
2387 --- 2.0.9 2004/01/05
2389 Fixed bug in Generic Frontend Server which could drop records exceeding
2390 preferred message size. Reported and fixed by Irina Dijour.
2392 Fixed calculation of package size for structured records in Generic
2393 Frontend Server. Reported and fixed by Irina Dijour.
2395 Fixed namespace for SRW/SRU diagnostics.
2397 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2399 --- 2.0.8 2003/12/22
2401 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2402 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2405 CQL changes to reflect recent changes to the specification:
2406 * Documentation talks about context sets instead of index sets.
2407 * Documentation talks about indexes instead of qualifiers.
2408 * The CQL-to-PQF transformer's configuration file now uses
2409 "index.set.name = <attributes>" instead of the old form
2410 "qualifier.set.name = <attributes>". (Both forms are still
2411 understood but the latter is deprecated.)
2412 * CQL terms with no explicit index specified are now interpreted as
2413 cql.serverChoice instead of srw.serverChoice (which of course
2414 behaves exactly the same.)
2416 --- 2.0.7 2003/12/16
2418 MARC conversion can now generate ISO2709 output in another
2419 character set. yaz-marcdump uses this facility if you invoke it
2422 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2423 functions from there can be used from C++.
2425 --- 2.0.6 2003/12/04
2427 Frontend server now transfers memory from decoded packages to stream
2430 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2431 references to show up.
2433 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2434 the ZOOM Abstract API. The older names for the same options are still
2435 also supported for the benefit of old applications.
2437 ZOOM-C supports "implementationId" and "implementationVersion" options
2438 to go along with "implementationName". These allow the user code to
2439 specify identification strings to be sent to servers.
2440 Add OID for the new ExtLite attribute set.
2442 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2443 as requested/supplid by Ere Maijala <ere@atp.fi>
2445 For generic frontend server, reverse the order of
2446 "toolkit-supplied / application-supplied" strings sent as implementationId,
2447 Name and Version. Also, remove the spaces around the slash. This brings
2448 the GFS in line with the behaviour of ZOOM-C on the client side.
2450 Add function ZOOM_scanset_display_term.
2452 yaz-client shows scan displayTerm if present.
2454 Utility yaz-iconv is now installed by default along with the man page
2457 Extend configure check for OpenSSL to use pkg-config where available (such
2460 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2461 server to specify uid/gid/mask for socket using the format
2462 unix:[user=uid,][group=gid,][umask=mask,]file=path
2463 If file= is omitted the existing format is assumed, e.g.
2465 in which case the mask is 0666 (rw for everybody).
2467 Major restructure of YAZ source. All source in libyaz is in src directory.
2468 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2469 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2471 Added man page for utility yaz-marcdump (used to be called marcdump).
2472 yaz-marcdump is installed by 'make install'.
2474 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2475 of incoming package failed.
2477 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2479 Change prototype of odr_perror: add const to message string.
2481 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2483 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2484 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2485 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2486 DNS lookup. There should not be any compatibility problems with this
2487 assuming that blocking=1 or 0 is used.
2489 Fix bad reference in UNIX comstack in function cs_addrstr.
2491 Fix for compilation on AIX.
2493 The generic front-end server (server/seshigh.c) now supports returning
2494 Init diagnostics to the client in User-information-field, in
2495 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2498 --- 2.0.4 2003/09/04
2500 Allow any CQL relation (not just all,any,exact,scr).
2502 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2503 that features the same UI.
2505 Implemented command update0 in YAZ client which is equivalent to
2506 update but uses old of Ext Update ASN.1.
2508 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2509 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2510 Previously no OID was used for this info.
2512 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2513 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2514 returns 'malformed search term' otherwise.
2516 SortResponse member resultCount now set to NULL in sort handler of
2519 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2522 Add three new utility functions for translating OIDs between various
2523 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2524 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2525 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2526 char *oid_to_dotstring(const int *oid, char *oidbuf);
2527 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2529 Reverted modifications for ES Update definition for z_IU0Update
2530 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2531 is back to YAZ 2.0.2.
2533 String value attributes for CCL parser.
2535 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2536 which their FirstSearch server returns in Init responses, sometimes
2537 carrying useful diagnostic information when Init fails. This has the
2538 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2539 "z39.50/oclcui.asn", where its definition is somewhat different from
2540 what OCLC document on their web-site, as required to interoperate with
2543 Support for anonymous authentication in yaz-client. Use the command
2546 * Fix the OID of the Index Data-local "admin" Extended Service from
2547 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2548 the 1000, which indicates a locally-defined OID, was a mistake.
2550 --- 2.0.3 2003/06/20
2552 Fix CCL directive @case handling so that it affects string match for
2553 both CCL keywords and qualifiers.
2555 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2556 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2557 Decoder has been updated with ASN.1 changes as listed in
2558 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2559 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2560 z_IUUpdate, remains unchanged.
2562 ZOOM_record_get may now return a record in a specific character set.
2563 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2564 "from" is the character set of record as returned by target. "to" is
2565 the character set to be returned. If omitted, "to" is UTF-8.
2567 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2569 New ODR utility, odr_getelement, which returns name of element for
2570 which encoding/decoding failed.
2572 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2573 in cases where a required element was omitted.
2575 Bug fix: some MARC8 sequences were not converted.
2577 New ZOOM option "step" which specifies number of records to be
2578 retrieved in one chunk. Used in conjunction with "start" and "count".
2580 SRW support for yaz-client. Use scheme http: to use it, e.g.
2583 yaz-client no longer does (un)intelligent character set conversions
2584 by default. Can be enabled with charset and marc_charset commands.
2586 xmalloc trace fix for 64-bit systems such as DEC alpha.
2588 Solaris 2.6 compile fix.
2590 New function, cql_strerror() translates SRW error codes, as returned
2591 by cql_transform_error(), into human-readable English strings. Used
2592 in yaz-client diagnostics when appropriate.
2594 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2595 converts it into a type-1 query which is sent to the server. This
2596 makes CQL available for use with all Z-servers, as opposed to the tiny
2597 minority that can handle CQL queries themselves.
2599 --- 2.0.2 2003/04/28
2601 New Debian package layout similar to the Redhat Package layout.
2603 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2604 and search result respectively.
2606 --- 2.0.1 2003/04/25
2608 Redhat package is now several packages: libyaz (runtime libraries),
2609 libyaz-devel (development and documentation, and yaz (utility programs).
2610 Package spec file by Morten Bogeskov.
2612 New member 'schema' in struct bend_fetch_rr which the name of requested
2613 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2614 handler MAY set this to reflect the schema of the returned record.
2616 New member 'display_term' in struct scan_entry. GFS now sets member entries
2617 and allocates scan entries to be filled by user scan handler. In previous
2618 version, entries member was allocated by the scan handler. That still works,
2619 but the GFS will ignore member display_term - assuming it was NOT set by
2620 the handler. The fact that the GFS now allocates the entries both allows
2621 for new members and makes a scan handler easier to write.
2623 Fix CQL lex buffer overflow.
2625 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2626 SRU default recordPacking is string.
2628 SRU protocol support for frontend server.
2630 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2632 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2634 Added scan for the ZOOM shell (zoomsh).
2638 * String Identifers for Schemas (Amendment 5).
2639 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2640 Old definition for schema
2641 Odr_oid *schema; /* OPT */
2646 Z_InternationalString *uri;
2647 #define Z_Schema_oid 1
2648 #define Z_Schema_uri 2
2651 * resultCount parameter to Sort Response (Amendment 1).
2652 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2654 Support for SRW 1.0 over HTTP. This is an optional feature and
2655 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2658 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2659 on the same port. SRW SearchRetrieveRequests are mapped
2660 to bend_init,bend_search,bend_fetch,bend_close.
2662 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2664 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2665 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2667 ZOOM connections are SRW based if schem http is used for hostname
2668 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2669 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2671 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2672 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2673 distance=n, order=true/false, relation=le, prox unit=word. If
2674 n is omitted, distance 1 is used.
2676 Fixed problem with C compiler include path in wrong order.
2678 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2679 on Solaris. Patch from Ko van der Sloot.
2681 New MARC decode API. All new functions operate on a yaz_marc_t
2682 handle. The most important new functions are: yaz_marc_create,
2683 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2684 decode and destroy respectively. Decoder can produce formats
2685 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2686 include/yaz/marcdisp.h.
2688 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2689 to UTF-8, UCS-32, wchar_t or Latin-1.
2691 * Prototypes for yaz_iconv_-functions moved to separate header
2692 include/yaz/yaz-iconv.h.
2694 Make a few private functions 'static' in unix.c. This prevents
2695 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2697 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2698 are set when Init Response is received.
2700 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2701 but returns diagnostic set as well.
2703 New function yaz_strerror which is a portable wrapper for
2704 strerror/strerror_r/GetLastMessage.
2706 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2707 is returned for MARC. If type is "oai", then OAI MARC is returned.
2709 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2712 --- 1.9.2 2002/11/26
2714 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2716 Fix bad race conditions on SIGTERM and terminate gracefully in
2719 Move retrieval (data1) module to Zebra since nobody seems to be
2722 Add GRS-1 render for ZOOM using same format as yaz-client.
2724 --- 1.9.1 2002/10/05
2726 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2728 Fix broken ESpec handling in data1 module.
2730 SGML reader parses comments and makes them part of the data1 tree.
2732 Added several type casts so that YAZ compiles as C++ code.
2734 ZOOM didn't handle PDU encoding failures properly.
2736 Added more Bib-1 diagnostics (approved extensions).
2738 GNU configure: better check for iconv.
2740 More portable use of accept, getpeername. Check for socklen_t. Use
2741 int/size_t if socklen_t is not defined.
2745 PQF parser rejects bad queries - including those with extra
2746 characters in them. PQF parser used to silently ignore that.
2747 Cleaner API for PQF added, which allows you to get detailed
2748 error information for bad queries (see yaz/pquery.h).
2750 Fixed bug in ZOOM_record_get for type "database".
2752 Implemented mini iconv library supporting conversions between
2753 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2755 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2757 --- 1.8.9 2002/08/20
2759 Fixed ZOOM C record cache so that preferredRecordSyntax and
2760 elementSetName is used to check for already fetched records.
2762 --- 1.8.8 2002/08/02
2764 Added three members in bend_initrequest structure to facilitate
2765 character set negotiation.
2767 Fixed a bug in frontend server that could cause indefinite
2768 loops under rare conditions.
2770 Revised character set utilities (charneg.h) so that encoding
2771 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2773 For PQF, directive @term <type> sets term type for Scan/Search.
2774 Here <type> is general, string, numeric, null. The term type
2775 is inherited - just like @attr.
2777 New call odr_set_charset that sets character set conversion for
2778 international-strings on a ODR stream. Prototype is:
2779 int odr_set_charset(ODR o, const char *to, const char *from);
2780 The InternationalString is still represented as C string in YAZ
2781 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2782 won't). On the protocol level, you can use any encoding.
2784 Support for UNIX sockets in ZOOM.
2786 Solaris recv sometimes returns errno == ENOENT. It is treated as
2787 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2789 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2790 both client and server. Code by Morten Bogeskov.
2792 --- 1.8.7 2002/05/22
2794 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2795 that they can be used directly from Visual Basic. You must recompile
2796 your windows APP if you're using ZOOM.
2798 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2799 Commands "lang" and "charset" sets language and character set respectively.
2800 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2801 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2803 Attributes from multiple CCL fields may be OR'ed rather than merged
2804 using directive "@field or". Fields are still merged by default -
2805 equivalent to "@field merge".
2807 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2810 Fixed bug in zget for parameter ExtendedServicesResponse.
2814 --- 1.8.6 2002/03/25
2816 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2818 Client displays USR.1:SearchResult-1 (hits per term).
2820 Additional Search Info for search in Generic Frontend Server.
2822 Fixed CCL parsing of "field=s".
2824 WIN32 installer - using the excellent NSIS software from nullsoft.
2826 Fixed CCL parsing of "field = - <number>".
2828 Added function yaz_marc_decode that decodes MARC for line mode
2829 display or XML (similar to that used by JZKit).
2831 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2832 Z39.50. But ISO/ILL was, however.
2834 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2835 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2837 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2838 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2840 --- 1.8.5 2002/02/03
2842 New YAZ client features: Command completion and new commands:
2843 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2844 Code provided by Jacob Poulsen.
2846 New call oid_trav, that visits all registered OIDs via callback.
2848 Function ZOOM_record_get now returns const char pointer rather than
2849 void pointer. It saves a lot of type casts.
2851 For YAZ client, command "auth" now allows you to set authentication
2852 in IdPass style. It is enabled when three tokens are given - order
2853 is user, group and password.
2855 Fix memory leaks in MARC record handling for ZOOM.
2857 New option for YAZ client, -k <kilobytes> that sets
2858 maximum record size. Similar to -k option for generic frontend
2859 server and yaz-ztest.
2861 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2863 Prefix query parser reports "fail" when bad attribute set is given.
2865 Fix in MARC decoder. Proximity logging. Fix for attribute set
2866 in scan handler for server. Patches by Shigeru Ishida.
2868 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2871 Configure option --with-openssl=<dir> now works when a directory is
2872 specified. Patch provided by Morten Bogeskov.
2874 New option for YAZ client, -u <auth>, that sets authentication.
2876 ZOOM fix: error information was sometimes "missing", since error
2877 was cleared/reset too when it shouldn't.
2879 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2881 --- 1.8.4 2002/01/04
2883 Scan for ZOOM API. New object ZOOM_scanset. New functions
2884 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2885 ZOOM_scanset_destroy.
2887 New ZOOM function, ZOOM_connection_last_event, that returns type
2888 of last event (such as "receive data", "send data", "apdu received",
2891 New ZOOM option, schema, that specifies schema for retrieval.
2893 New CCL feature. Qualifiers can be aliases for one or more
2894 other qualifiers (if more than one is given, OR is used).
2896 ZOOM uses named result sets if target supports it.
2898 Two new YAZ client commands: . (dot, which sources a script of YAZ
2899 client commands), and ! (to execute shell command.). Implemented
2902 Working on Debian packages.
2904 --- 1.8.3 2001/11/19
2906 YAZ client enables named result sets only if target supports it.
2908 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2910 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2911 with key="host" to get same result.
2913 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2914 Function Z3950_resultset_record(s) returns references to records
2915 "owned" by resultset. To become owner use Z3950_record_clone.
2917 Function z_ext_record handles Extended Services. Thanks to
2920 --- 1.8.2 2001/11/12
2922 CCL Parser fix: ignore token comma when dealing with and-lists.
2924 Documentation updates for COMSTACK.
2926 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2927 Changed prototype Z3950_records. For some functions, int parameters
2928 were changed to size_t.
2930 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2933 New MARC decode/display function, marc_display_exl, which properly rejects
2934 non-ISO2709 records. YAZ client uses it.
2936 --- 1.8.1 2001/10/29
2938 Fix bug: local attribute set wasn't set correctly in PQF strings.
2942 * Old Z39.50 codecs no longer supported.
2944 Added ZOOM C binding. See http://zoom.z3950.org/
2946 Renamed states for COMSTACKs to avoid confusion with events.
2948 Implemented cs_look and proper cs_rcvconnect.
2950 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2952 Configure detects POSIX threads on OpenBSD.
2954 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2955 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2957 When error is returned from present handler, non-surrogate diagnostic
2958 is returned in present response (and fetch handler is no longer called).
2960 * Minor adjustments to pquery parser (PQF). Token characters may be
2961 escaped by using backslash (C-style).
2963 PQF parser allows string attribute values to be specified. For @attr,
2964 non-numeric characters after the equal-sign are treated as strings
2965 (e.g. @attr 9=title).
2967 CCL trunction character may be defined (@truncation in file)
2969 * function zget_ExtendedServicesRequest sets waitAction to
2970 waitIfPossible (was wait).
2972 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2975 CCL operator names may be set in field definition files (CCL_bibset).
2976 See ccl/bib1 for an example.
2978 Fixes in ASN.1 compiler for C++ compatibility.
2980 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2981 and "op_or" to avoid conflict with C++.
2983 Fixed problem with GNU readline detection on Redhat 7.0.
2985 Added step-size for Scan backend handler.
2987 Fixed bug that made the frontend server crash when no attribute
2988 set was specified for scan.
2990 Front-end server automatically switches to original working directory
2991 when installed as an NT service. Previously -w had to be specified to
2994 Added extended attributes for retrieval module (data1), so that data1
2995 records carry d1_readXML/SGML attributes. d1_read also supports
2996 null-data rules ( <tag/>)
2998 On UNIX when POSIX threads are available, a separate library libyazthread
2999 is created. Programmers should link with that library and the yaz library
3000 when using threads. The reason for the split was that some applications
3001 on Linux, such as Apache, doesn't work well when using shared objects that
3004 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3005 (or any frontend server) in SSL mode by specifying ssl: followed by
3006 address. Only tested on UNIX.
3008 Added feature for CCL module. Virtual structure s=al or s=ol generates
3009 and-list and or-list respectively instead of phrase search.
3013 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3014 log_mask_str. This was done to avoid name conflicts with other libraries
3015 (such as other PHP extensions).
3017 Added raw OID member for preferred record syntax (request_format_raw)
3018 and returned record syntax (output_format_raw) for backend fetch method.
3020 Config file yaz-config now accepts options so that it returns specific
3021 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3023 Shared library support for UNIX using GNU libtool.
3025 * Modified backend interface. Request/Response struct's replaced by
3026 one read/write C struct. For example bend_fetchrequest and
3027 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3028 Every handler - even search has to be registered in bend_init
3029 handler. This means that the YAZ library no longer refers to
3030 external functions and it makes it possible to make the whole
3031 thing a single DLL/SO.
3033 Added Segment handler for backend server.
3035 Added Zmbol/Zebra administrative functions to YAZ client.
3037 Threaded frontend server on UNIX (when POSIX Threads are available).
3038 Starting the server with option -T enables multi-threading.
3042 Added configure option --enable-comp/disable-comp to control use
3043 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3044 located in sub directory asn.
3046 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3047 in ${exec_prefix}/bin along with the other programs yaz-client and
3050 GNU automake used to maintain makefiles.
3052 Added several OID's.
3054 Changed retrieval module so that we can load records with no abstract
3055 syntax defined. Tagpaths in these records are fully composed of string
3058 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3062 On UNIX, the generated makefile now supports a proper 'make install'.
3063 The prefix can be set via GNU configure to set the install location
3064 (default is /usr/local).
3066 * YAZ programs client and ztest were renamed to yaz-client and
3067 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3068 locations, such as /usr/bin,/usr/local/bin,etc.
3070 * YAZ Header files were moved from include to include/yaz. YAZ Header
3071 files are referred to as include <yaz/log.h> rather than <log.h>.
3072 The YAZ include path (-I ..) is therefore the same as before. Programmers
3073 should update their #include statements or use -Ipath/include/yaz
3074 instead. The main motivation for doing this change is that YAZ header files
3075 can be installed in "standard" locations /usr/include,/usr/local/include
3076 without introducing conflicts, since ALL YAZ header files are stored
3077 in subdirectory yaz (under /usr/include for example).
3079 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3080 rather than project/workspace files. We switched because project files
3081 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3084 Changed name of logging function, logf, to yaz_log, to prevent name
3085 clash with some math-log functions. The YAZ header log.h defines logf
3086 to yaz_log (#define) so there should be no incompatibilities by this
3089 Added bend_start/bend_stop handlers for server. These handler are
3090 called on start/stop of server. For windows they are called whenever
3091 a service is started/stopped.
3093 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3094 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3095 in util/yc.tcl. The auto-generated C code structures are, in a few
3096 cases, incompatible with the old decoders. There are differences in the
3097 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3098 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3099 The preprocessor variable ASN_COMPILED is defined when the compiled
3100 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3101 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3102 wish to use the old encoders/decoders you can specify --disable-yc
3105 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3106 version so that it supports both new - and old version of DB Update
3108 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3109 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3110 change. The name parameter can be set to 0 in which no name is specified
3111 for the construction. The macros odr_implicit and odr_explicit sets name
3112 parameter to zero for the construction involved. New macros
3113 odr_implicit_tag and odr_explicit_tag are similar to the others,
3114 except that a name parameter is added. For programmers' that don't use
3115 ODR they probably only need to change the call to z_APDU and z_External.
3117 Added access control facility by interfacing the TCP wrapper library.
3118 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3119 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3120 name of the daemon and enables the access control as specified in
3121 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3123 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3124 den Dool <H.M.vdnDool@kub.nl>.
3126 Added reference ID parameter to most functions in server API - refer
3127 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3129 Changed name of ccl library to libccl.a (was ccl.a).
3131 Fixed bug in decoder for Explain (Category TargetInfo).
3133 Added support for GNU readline in client. Thanks to Jacob Poulsen
3134 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3136 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3137 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3138 IMPLEMENTATION! This change was made to the development version before
3139 the ZIG decided to retract the amendment. If any users MUST be
3140 compatible with the original Update definition, PLEASE CONTACT US, and
3141 we will include a separate definition corresponding to the old Update
3142 ES. Note that because of the change to the ASN.1 of the
3143 TaskPackageRecordStructure we cannot define a single structure that
3144 will support both versions.
3146 * Added const modifier to buffer parameter for some ODR/BER encoding
3147 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3148 completeWAIS, odr_dumpBER.
3150 Fixed bug in client.c which caused a crash when a scanResponse didn't
3151 contain positionOfTerm.
3153 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3154 * will cause an error in a client if a non-YAZ target sends both a
3155 * list of Scan entries and non-surrogate diagnostics.
3157 Retrieval module enhancements. Tag sets may be typed in the reference
3158 to it. From the .abs-file the "tagset" directive takes a third optional
3159 integer type for the tag set referenced. From a .tag-file the "include"
3160 directive takes a third optional type as well. The old "type" directive
3161 in the tag set itself is still recognized but acts as the default type
3164 Backend interface change. Individual Scan terms returned from bend_scan
3165 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3166 in include/backend.h.
3168 Retrieval module enhancements. Multiple tag sets and attribute sets may
3169 be specified in abstract syntax specs. Revised the error/warning for
3170 logging messages reported by the retrieval module when reading the
3173 Object Identifier system (oid_..) changed. The API is backwards
3174 compatible but the oid-routines now allocates new OID's when needed.
3175 Raw OID's may be specified in oid_getvalbyname.
3177 YAZ now uses GNU configure to generate Makefile(s).
3179 * Minor changes in some of the member names of DeleteResultSetRequest and
3180 DeleteResultSetResponse. See include/proto.h.
3182 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3183 and added member 'languages' in TargetInfo (which was missing).
3185 Changed the way attribute sets are handled in the retrieval
3186 module. These are now cached, just like the abstract syntaxes
3189 Changed YAZ so that it links with compiled ASN.1.
3191 Added Explain-schema definitions and mapping routines. The following
3192 Explain categories have been implemented: AttributeDetails,
3193 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3195 Fixed minor bug in Windows version of Server Library.
3197 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3199 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3201 Added EXTERNAL: UNIverse Resource Report (non-standard).
3203 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3204 ENUMERATED and SET OF.
3206 * Added 'const' to some of the char pointer arguments for the
3207 functions, data1_read_node, data1_getelementbytagname,
3208 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3211 Fixed bug in data1_insert_taggeddata - the last_child member of
3212 parent wasn't initialised.
3214 * Changed data1_read_record and data1_read_node so that the supplied
3215 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3216 doesn't refer to any parts of the "SGML"-buffer.
3218 Fixed bug in server library (Windows version of statserv_remove).
3220 * Changed code so that it compiles as C++. The type definition
3221 of Odr_fun which is a member of Odr_arm was changed. The result is,
3222 that an explicit typecast is needed for the fun pointer when
3223 using Odr_arm - as in:
3224 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3226 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3228 Implemented the new structured date and time definition as approved
3229 by the ZIG. Added schemaId element to the specificTag in Espec-1
3230 (also approved at the last ZIG). Thanks to RVDM.
3232 Added some Object identifiers (RVDM).
3234 Changed the Update Extended Service (RVDM).
3236 Added command "refid" to client which specifies referenceId for
3237 the following requests.
3239 Implemented extended service handling for server. See ztest.c
3240 for an example as well as backend.h. New handlers are registerd
3241 in the Init handler.
3243 * Changed interface for sort in server.
3245 Added new members to statserv_options_block. It allows a server
3246 to read options from another source than just the command line. Thanks
3247 to Charles Woodfield.
3249 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3250 renamed to zboolean. Some C++ compilers complained about the name.
3252 Minor changes to gils.abs. Added index 's' (sort) on title
3253 and date/time-last-modified.
3255 --- 1.4pl2 1998/1/30
3257 Fixed bug in server library regarding inetd mode (-i). This bug
3258 was introduced by release 1.4.
3260 --- 1.4pl1 1998/1/29
3262 Added sort facility in client and backend server interface.
3264 Fixed problem with dependencies in Makefile(s).
3266 Fixed bugs for encoders/decoders of extended services and
3269 Implemented sub-tree feature for schemas. Sub-trees are
3270 referenced in *.abs-files. See explain.abs for an example
3271 of the use of this feature.
3273 Modified bib1.att; local attributes for ANY didn't include
3274 ANY itself (only affects use of the retrieval module).
3276 Fixed bug in plain SGML reader in function data1_read_node:
3277 tags with prefix "var" was incorrectly interpreted as variants.
3279 Added feature "sub-schemas" to enable references to - and definitions
3280 of - group of elements.
3282 * Removed member parent from type data1_element (in data1.h).
3284 Implemented function odr_nullval() that returns the value of
3287 * Removed member num_children from data1_node (in data1.h).
3289 Made NT service interface part of the server library. The
3290 function statserv_main uses the NT service when required and
3291 calls the statserv_start / statserv_close routines.
3293 Routine zget_SearchRequest and zget_PresentRequest fills
3294 resultSetName/Id member with "default" instead of "Default".
3296 Fixed memory leak in server. Request queue member wasn't freed.
3298 Fixed nmem_exit so that memory is freed.
3302 Revised the CCL parser utility to be thread safe.
3304 Added function, oid_ent_to_oid, to replace the function
3305 oid_getoidbyent, which is not thread safe.
3307 * Added nmem_init and nmem_exit to initialize and release
3308 NMEM resources. Function nmem_init should be called once in the
3309 initial thread before NMEM/ODR is used. statserv.c and client.c
3310 have been changed accordingly. The change was necessary to make
3311 NMEM thread safe. The NMEM memory pool is shared amongst threads
3312 in a process. Unix-based applications will still work fine without
3315 Added NT Services interface for the the Z39.50 (statserv) Server.
3316 Refer to the ztest.c source on the usage.
3318 Windows 95/NT port using MSVC5.0. Project files are included in the
3321 * Defined new 'global' handle for the retrieval (data1) system. The
3322 new handled, data1_handle, describes the state of the data1 system.
3323 This handle is passed as first argument to virtually all
3324 data1 related routines. The functions data1_create and data1_destroy
3325 creates and destroys a data1 handle respectively.
3327 Added ODR encode stream member to all backend request structures
3328 init, search, scan etc. This stream should be used to allocate all
3329 memory used for the response when thread safe operation is needed.
3331 Changed the comstack utility, cs_addstr, to be thread safe. The
3332 returned hostname string returned by the function is now part the
3335 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3336 function. The cs_straddr takes a COMSTACK handle as argument, so this
3337 function must be used after cs_create and before bind/connect.
3338 This function is thread safe.
3340 Moved test server to 'ztest' directory - generic server code still
3341 in 'server' directory.
3343 Made prefix query (pquery.c) utility thread safe.
3345 Added new function modifier YAZ_EXPORT to 'export' public DLL
3346 functions when using windows (see include/yconfig.h).
3348 Added definitions to the OID database (util/oid.c) (RVDM).
3350 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3352 Added call to ccl_rpn_delete in client program.
3354 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3355 release of RPN structure.
3357 Added support for C++, headers uses extern "C" for public definitions.
3358 With input from RVDM.
3360 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3361 Thanks to Ronald van der Meer (RVDM).
3363 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3365 Added support for private extensions to the OID database
3366 (oid_setprivateoids()). Thanks to RVDM.
3368 Added optional, physical ANY (key replication)
3370 Fixed null-reference problem in GRS-1 output filter.
3372 Proximity operator added to Prefix Query Format (PQF).
3374 In test client command "base" accepts multiple databases.
3376 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3380 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3382 Smallish bug-fixes in the new encoders/decoders (explain).
3384 Bug fixed in DeleteRequest.
3386 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3388 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3390 Added SOIF syntax (using private OID for now) to retrieval module and client.
3392 Added Update extended service.
3394 Added SearchResult-1 additional info structure.
3396 Added optional CCL (ISO8777) interpreter as separate module. Available
3399 --- 1.2 1996/6/10 (1st anniversary release)
3401 Added Summary record syntax. Lightly tested.
3403 Added OPAC record syntax. Untested.
3405 Added ResourceReport service encoders/decoders. Untested.
3407 Fixed bug in z_Unit - wrong tagging on unitSystem.
3409 Fixed bug in the DiagRecs decoder.
3411 Added options for max PDU size and session timeout to frontend-server.
3413 Added documentation of query-language parsers and other supporting utilities.
3415 [frontend-server] Added Attribute set to the bend_scanrequest API.
3417 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3418 surrogate diagnostics were generated.
3420 [retrieval] Allow multiple local values for attribute.
3422 [retrieval] Allow multiple attributes per element in .abs files. index type.
3424 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3426 --- 1.1pl2 1996/4/10
3428 Minor changes, mostly specific to Zebra's requirements (retrieval)
3432 Repaired bug in frontend server when running multiple listening
3433 endpoints in dynamic mode.
3435 z_External() now won't break if a known, ASN.1 value comes encapsulated
3436 in an octet-string. The value will pass through unmodified in an Odr_oct.
3438 Added a bit of code to the demo client to decode & display
3439 ASN.1-structured records represented in the octet-aligned branch of
3440 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3442 Added z_ext_getentbyref() to the ASN module. Doc updated.
3444 * Completed the SCAN definition in the ASN module. This may break SCAN
3445 code based on older YAZ-versions at compile-time. The fix is easy -
3448 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3449 under the SCAN definition. Remember to initialize this, server-people.
3451 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3452 that this does not extend to ODR and ASN.
3454 Comstack allows insertion of established socket (primarily for
3455 inetd-operation of servers). Doc updated.
3457 Front-end server can now start from the inetd in TCP mode. Doc
3460 --- 1.0pl4 1996/1/24
3464 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3465 the rank and record number.
3467 Adjustments to the frontend server.
3469 Fixed diagnostic BER dumper. It ignored the file argument.
3473 Various changes to retrieval module.
3475 Changed the union discriminators of the protocol files from enums to
3476 ints paired with #defines.
3478 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3481 *Changed operator in the RPN structure to 'roperator', again to avoid a
3484 Fixed problems in Explain decoders/encoders.
3486 --- 1.0pl2 1995/12/6
3488 Memory bug in log module fixed.
3490 --- 1.0pl1 1995/12/5
3492 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3494 Bug in Explain DatabaseInfo module fixed.
3496 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3500 The shift to v1.0 signals that we now consider the *core* functionality
3501 of YAZ reasonably stable (the core being more or less equivalent to
3502 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3503 tested (Explain not at all - though that will happen soonish).
3505 Minor changes to code to support Windows port.
3507 Various minor changes after we're getting to use GRS-1 & co. more.
3509 Added Espec-1 format.
3511 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3512 of the protocol and it cannot be selected when encoding (maps into 'string'
3513 when decoding). Needed to talk to some servers.
3515 Demo client can request simple element set names.
3517 Added Diagnostic Format encoders/decoders.
3519 Added simple Close handling to frontend server (no hooks for resource
3520 reporting yet), and demonstration client.
3522 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3524 --- 1.0b3 1995/08/24
3526 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3527 handled incorrectly when records were requested in the searchResponse. This
3528 will only affect you if you use the frontend-server.
3530 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3531 Test-client will ask for and print GRS1. Ztest will return dummy records
3534 Added Explain encoders/decoders to the service-level API. Untested.
3536 Added Extended Services: Item Order encoders and decoders to the Service-
3537 level API. Untested. We could use a recent copy of the pertinent bits
3538 of the ILL protocol to add those bits.
3540 Added diagnostic format 1 encoders/decoders to the service-level API.
3543 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3544 odr_cons.c, which causes a more correct output.
3546 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3547 was always set to 0 when no records were requested in the searchRequest.
3549 * Added better external-handling. This shouldn't harm old code that
3550 *encodes* externals. It can break code that looks for a
3551 'single-ASN1-type' representation, since those types that are known
3552 are now decoded immediately. Look at the SUTRS sample code in
3553 seshigh.c and client.c. Documentation updated.
3555 Handling of structured records in bend_fetchresponse. Length -1 marks
3556 structured record, type is deduced from format field.
3558 --- 1.0b2 1995/06/27
3559 Fairly quick maintenance release to add SUTRS support.
3561 Fixed handling of SUTRS records in the demonstration client.
3563 * Added format field to the bend_fetchrequest and bend_fetchresponce
3564 structures of the backend API (frontend server). When the record is
3565 returned, the value of the format field is mapped to an OID. The
3566 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3567 of the record. The special value VAL_NONE in the bend_request means
3568 that no specific format was requested by the client. Documentation
3569 updated accordingly. Test server (ztest) will return a fixed dummy
3570 SUTRS record if your client requests SUTRS.
3572 Documentation updated accordingly.
3574 You can now set external libraries and RANLIB support in the top-level
3578 First public release.
