1 Windows installer of YAZ includes YAZ4J as a component.
3 CQL: allow "extra terms" again, by default. Thus, the CQL parser
4 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
5 and earlier. CQL parser may operate in strict mode where queries
6 not conforming to the standard BNF are rejected (syntax error).
7 Whether the CQL parser operates in strict mode is controlled with
8 cql_parser_strict . Strict mode enabled with option -S for utilities
11 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
15 New charset, MARC-8c, which is like MARC-8 but allows control characters
16 0x01 through 0x1F, except ESC to be passed through verbatim.
18 Fix a problem with duplicate sub field character in MARC output. Problem
19 happened only when output was MARC-8 encoded.
23 yaz-ztest: Use hash for fake hit count. Before, random number was used.
24 This is problematic for unit tests using yaz-ztest. This patch also makes
25 a hash for CQL queries. For RPN, any term with a leading digit will be
26 treated as pseudu hit count (to force any particular hit count by a client).
28 yaz-ztest: return unique MARC dummy records. Beyond record offset
29 24, the author surname is patched with offset to make all records
32 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
33 on system wide default (/proc/sys/net/ipv6/bindv6only).
34 @4 binds to IPV4 only. @6 binds to IPV6 only.
36 Update CQL API documentation a bit
38 CQL: don't accept extra terms for queries. Makes the CQL parser
39 stricly conformant to the standard.
43 GFS: scan handler gets extra_args from request and may return extra
44 response data . That's for SRU only.
46 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
50 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
52 OPACXML: sync spelling of availabilityDate in XML to that of Schema
53 opaxxml.xsd. The schema had the correct spelling of this member always.
54 The ASN.1 was mis-spelled and still is (API change) - we are
55 not changing this. However, the OPAC to XML conversion had yet
58 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
61 New function, z_ext_record_oid_nmem, which is similar to
62 z_ext_record_oid but takes NMEM rather than ODR
66 ICU: New conversion element 'join' which joins tokens into one
67 with a custom character given by rule attribute.
71 New GFS search member: present_number. This is a hint to the
72 search handler how many records are going to be fetched immediately
73 following search. There's no guarantee that it's going to be the case,
74 since it depends on hit count (for Z39.50 piggyback) and whether errors
77 Make a few functions static (private). The functions getbyte_stream,
78 ungetbyte_stream and yaz_gets are now private. They were never declared
81 yaz-marcdump: exit(5) for serious decoding errors
83 ISO2709 decoding: be more picky WRT header
85 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
86 was only used as to indicate that next-result-set-position should be
88 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
89 Based on patch from Ashley Sanders.
91 Make some functions static/private in PQF parsing. Those functions were
92 never declared in a public header and so should not be in use by
93 applications based on YAZ.
97 ZOOM: special options to control APDU logging.
98 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
99 logging of APDUs until "saveAPDU" option is set again. If logging is
100 already enabled the effect is that current APDU buffer is cleared.
101 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
102 logging (default behavior on new connection).
103 The APDUs sent/received can be obtained by using
104 Using ZOOM_connection_option_get(c, "APDU") or
105 ZOOM_connection_option_getl(c, "APDU", &l).
107 GFS: relay implementation_version from backend
108 From 3.0.40 and later, implementation_version from backend was
109 not used in init response at all.
111 --- 4.2.46 2012/11/15
113 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
114 mode at all. Probably never did.
116 Make a new version of ztest.pem that, at least, is not expired.
118 --- 4.2.45 2012/11/13
120 Fix description of CCL directive 'case'.
122 More tight checking of form arguments (yaz_uri_to_array). Makes
123 YAZ better at rejecting big and/or bad POSTs.
125 SRU decoding does not report more than up to 10 invalid arguments.
127 rpn2cql: less quotes in generated terms. Semantics unchanged, but
128 it's prettier this way.
130 --- 4.2.44 2012/10/25
132 New utility yaz_decode_init_diag. Defined in proto.h.
134 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
135 given for unix local socket.
136 The COMSTACK string for doing so is:
139 unix:/myfile:tcp:localhost:9999/mybase
140 unix:/myfile:localhost:9999/mybase
141 unix:/myfile:http://fakehost/mybase
143 debian: Use dpkg-buildflags in build process.
145 --- 4.2.43 2012/10/19
147 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
148 global's SRU service uses a recordPosition scheme starting from zero.
149 First record's position should be one
150 according to the standard.
152 --- 4.2.42 2012/10/18
154 Allow more namespaces for SRU. This is to allow, for example, an
155 incorrect namespace returned from server
156 http://services.igi-global.com/sru .
158 Minor fixes for compilation on Windows.
160 --- 4.2.41 2012/10/11
162 daemon: log total number of bad signals from child on stop so that it
163 is more easy to spot problems with child worker processes.
165 retrieval: empty backend name attribute omits element set
166 from being used in retrieval.
168 --- 4.2.40 2012/10/04
170 Implement Solr sort strategy "solr", similar to sru11 sorting.
171 This will implement the correct parameters on Solr requst to do
174 --- 4.2.39 2012/09/28
176 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
179 MARC: Extra/missing indicator handled for MARCXML.
180 The indicator length is given in header and is the same for the
181 whole record. If attributes ind1, ind2 are missing, then content
182 character defaults to blank. Extra indicator attributes (beyond)
183 indicator length are treated as an error.
185 Reformat: delete trailing whitespace
187 --- 4.2.38 2012/09/17
189 MARC: fix non-ASCII characters for leader. This is to ensure we can
190 generate XML in UTF-8.
192 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
193 in one node with structure word.
195 --- 4.2.37 2012/09/04
197 yaz-json-parse: JSON output may be pretty printed by using option
200 Increase default value of max message for Z39.50 Init for GFS, ZOOM
201 and yaz-client. Old value was 1 MB. New value is 64 MB.
203 --- 4.2.36 2012/08/22
205 yaz-client: don't display bogus records from SRU servers. Some SRU servers
206 return more records than given by *maximumRecords*. Skipping those in
209 record_render: simplify buffer return handling and fix at least one bad
210 memory reference, that broke the test_embed_record sometimes.
212 Allow http://user:pass@host notation for yaz_url_exec.
214 zoomsh: allow shell command to be executed. Via the system(3) call.
216 yaz_poll: Allow num_fds == 0
218 yaz-client: fix bad encoding of "itemorder item". The itemorder
219 item <no> - command forgot to use length of encoded Item Request
220 package. Error present since YAZ 3.
222 yaz-ztest: fix bad usage of session handle. Bug was introduced when
223 result sets were saved (271a9c83).
225 SRU recordPacking: guess record packing in response rather than looking
226 at the recordPacking element which, OF COURSE, changed semantics in SRU
229 Decode SRU 2.0 responses. The official namespace for responses, according
230 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
231 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
232 nature.com's server, however, usee namespace
233 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
234 we are now using a glob-expr to match up the namespace. ZOOM C and
235 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
236 I can not find a single real example showing the "real" namespace in
237 the documentation from OASIS. The namespace for requests is different
238 from responses, but this is not added to YAZ yet, when we don't encode
241 --- 4.2.35 2012/06/26
243 zoom/record_render: add support for Base64 decoding fo MARC records
244 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
245 which will decode base64 + ISO2709 marc-8 encoded material from text node
248 --- 4.2.34 2012/06/07
250 Add missing definitions ZOOM_resultset_get_facet_field_by_index
251 and ZOOM_resultset_facets_names.
253 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
256 Change APDU dump printing to avoid long leading blanks. For levels 16
257 or larger the level is shown and the indentation is truncated but
258 recursed with modula 8. This makes it still reasonable easy to read
259 - even for nested BER dumps.
261 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
262 return 0 (incomplete package) in case where the BER package was
263 considered too nested (return value of -2).
265 dumpber: lines of level 15 are not indented further. Two spaces per
266 indentation; indentation 15 or more is indented to a fixed indentation
267 and augmented with a level=<no> indication.
269 zoomsh: increase max size of command+args
271 GFS: No limit in RPN buf size in CQL to RPN conversion.
273 --- 4.2.33 2012/05/09
275 New function for daemon utility, yaz_daemon_stop .
277 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
279 --- 4.2.32 2012/04/25
281 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
282 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
284 --- 4.2.31 2012/04/23
286 YAZ daemon utility relays SIGUSR1 to child process.
288 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
289 would result in en empty database list - which in turn would result in
290 encoding failure for search.
292 Fix reading beyond string in yaz_sort_spec.
294 --- 4.2.30 2012/04/11
296 Add two new SRU diagnostics:
297 236: Access to specified database denied
298 1015: Init/AC: Maximum number of simultaneous sessions for Userid
300 Document the very useful ZOOM-C option "apdulog".
302 CQL to RPN: term may be passed through verbatim. This is enabled with
303 truncation.cql . The assumption being that the term is already CQL.
305 --- 4.2.29 2012/03/20
307 record_conv: leader spec may be given for marc element.
308 The leader spec is given as attribute leaderspec for element marc.
309 For example to convert a MARC21 record from MARC-8 to UTF-8:
310 <marc inputformat="marc" outputformat="marc"
311 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
313 record_conv: allow user-XSLT params. For example:
314 <xslt stylesheet="MARC21slim2DC.xsl">
315 <param name="myparameter" value="myvalue"/>
316 <param name="otherparameter" value="othervalue"/>
319 record_conv: fix error handling for missing marc charsets.
321 CQL: fix extra terms in wrong order.
323 --- 4.2.28 2012/03/06
325 record_conv: modify new API for conversion types. The conversion types
326 may be passed in new functions yaz_record_conv_configure_t and
327 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
329 Avoid mixed statement/variable declare; fixes compilation with Visual
332 --- 4.2.27 2012/02/28
334 Add non-standard SRU diagnostic: 235: "Database does not exist".
335 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
336 Update SRU to Bib-1 diagnostic maps accordingly.
338 CCL: add two new diagnostics for unsupported masking. The new
339 diagnostics are: "Embedded truncation not supported" and
340 "Single charcacter mask not supported".
342 --- 4.2.26 2012/02/23
344 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
346 --- 4.2.25 2012/01/11
348 Build YAZ for Ubuntu Oneiric.
350 CCL: allow parantheses for proximity operands. For example CCL query
351 (a) % (b) is now allowed.
353 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
354 marked dead, rather then being destroyed. If not, the session memory is
355 being free'd before the search/scan handler is finished. Also destroy
356 'request' memory in request_release rather than in various places,
357 which resulted in leaks from time to time.
359 --- 4.2.24 2011/12/21
361 cql_sortby_to_sortkeys: honor sort prefix.
363 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
364 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
365 The rpn2cql family of functions now always returns quoted CQL terms.
367 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
369 --- 4.2.23 2011/12/15
371 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
372 sequence is treated as one. For example, &&a=b&&&c& is identical to
375 --- 4.2.22 2011/12/05
377 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
378 APDUs for a connection to a WRBUF.
380 --- 4.2.21 2011/11/23
382 Fix cql_sortby_to_sortkeys. Completely broken before.
384 Make CCL's @truncation work again.
386 --- 4.2.20 2011/11/09
388 New ZOOM connection setting: tproxy. It's like proxy, but does not
389 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
390 to set resolved address + port for a connection outside ZOOM itself.
392 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
394 --- 4.2.19 2011/11/07
396 Fix uninitialized variable in Solr spell support (could cause SEGV
397 for SRU response decoding).
399 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
400 back-end's addinfo through into the ZOOM response addinfo.
402 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
403 they are separated by a colon and a space rather than simply
406 --- 4.2.18 2011/10/28
408 Add support for Solr spell-checking/suggestions through ZOOM.
409 If a Solr target has been configured correctly for spelling-checking
410 and suggestions, these will now be returned on the ResultSet option
411 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
413 --- 4.2.17 2011/09/28
415 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
416 with a flag whether to substitute escape sequences or not.
418 --- 4.2.16 2011/09/22
420 Fix nmem_strsplit_escape to substitute escape char properly.
422 New option for zoomsh -e , which makes it abort on first error and
423 return process exit code to indicate success/failure.
425 YAZ options utility supports special option -- which makes all it treat
426 all following arguments as non-options.
428 --- 4.2.15 2011/09/16
430 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
431 searched if absolute filename is given.
433 Fix conv_xslt() error-reporting when stylesheet is not found.
434 (The value of fullpath is meaningless in this situation.)
436 --- 4.2.14 2011/09/07
438 Fix problem in CQL sort node creation: un-initialized memory.
440 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
441 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
442 CQL sortby depending on whether Type-1 or CQL is actually sent to the
445 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
446 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
448 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
449 will make it possible to use both single-character mask (#) and wildcard (?)
450 in CCL . Throw diagnostic for left truncation because that is not supported
453 --- 4.2.13 2011/09/01
455 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
456 cases using escapes (\-sequences) and masking.
458 PQF parse fix: A trailing backslash followed by end-of-string (\0)
459 would result in a read one byte beyond string.
461 rpn2ccl may use Z39.50 masking for terms (t=z).
463 ICU check fix. Don't include library -lCrun on Solaris, unless present.
465 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
466 not --cppflags (which seeems like an error in icu-config).
468 --- 4.2.12 2011/08/27 RPM package only
470 cql2ccl: fix conversion of terms: operator characters were not
473 --- 4.2.11 2011/08/25 RPM package only
475 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
476 CCL parser will map both # and ? to their regular expression
477 quivalents (. and .*).
479 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
480 of reserved CQL characters.
482 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
483 is, so that they are passed through.
485 --- 4.2.10 2011/08/24
487 ZOOM SRU mode: more aggressive re-connect.
489 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
490 made available as a utility function, declared in <yaz/logrpn.h>
492 rpn2cql_structure() supports proximity nodes (except that the Type-1
493 proximity node's "exclusion" binary is ignored, as there is no way to
494 express that in CQL). Fixes bug #4564.
498 Fix SEGV that could occur if set command of zoomsh was given without
499 value (2nd argument).
501 Fix SEGV that could occur if unsupported transport was given for
502 COMSTACK - say https (when SSL was unavailable).
504 Build yaz-url on Windows too.
508 New utility to get web content. Header is url.h. A command line tool
509 yaz-url is part of the distribution and packages.
511 Fixes for SSL COMSTACK (when gnutls is in use).
513 New functions yaz_base64{encode,decode}. Header is base64.h.
517 ZOOM C includes HTTP response buffer as additional info if it fails
518 to decode the SRU response.
520 Make wrbuf_json_puts available.
524 zoom: throw diagnostic for invalid value for option "sru". Before a
525 bad SRU request was sent.
527 Adding new utility wrbuf_vp_puts.
529 Add cclxmlconfig.obj to win/makefile. It was missing completely.
533 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
534 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
535 redirect was used at the same time.
537 MARC line mode decoding: be less picky about length given - first
538 5 digits of header that is.
540 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
542 Changes to decoding of SRU records: a record with recordPacking=xml is
543 modified with a new root element <yaz_record> if the recordData contains
544 multiple children elements. This is to make the record XML parseable
547 RPN to Solr conversion: encode special characters.
549 Generic Frontend Server: fix uinitialized member, stepSize.
553 Fix a bug in SRU decoding of records.. The database records stored
554 had un-initialized memory, but it would only be seen with yaz_record_render
555 and type_spec="ext" .
557 Fix a bug in ccl_qual_dup introduced in 4.2.3.
561 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
565 Add new utilities to convert from CQL to CCL . These utilities have
566 prefix cql_to_ccl defined in cql.h.
568 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
569 lead to memory heap corruptions when ICU utilities were in use.
573 Make compilation work without Libxml2.
575 yaz-client: remove redundant blanks in display of searchResult-1 term
580 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
581 resulting CQL node (tree) in a new node CQL_NODE_SORT.
583 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
584 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
585 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
586 Note that the CQL sortby spec is only converted when the GFS is already
587 converting from CQL to RPN (cql2rpn element).
589 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
590 specify whether to collapse delimitors or not. The existing nmem_strsplit
591 do collapse (collapse parameter = 1).
593 Windows installer: For NSIS, set InstallDir depending on x86/x64.
595 Rename internal func yaz_use_attribute_create. While non-static, this
596 function is not declared in a public header.
600 Add -lCrun when linking with ICU on Solaris.
602 More quicks character set conversions for OPAC records.
606 fix problem with record_render: records were converted (character set
607 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
611 SRU: add methods for handling DADS SRU-proxy facets.
613 Separate OPAC record character set for ZOOM_record. yaz_record_render
614 allows a character set given as charset=from/opacfrom,to where 'from' is
615 the character set of a bibliographic record, 'opacfrom' is character set
616 of OPAC record and 'to' is the target character set.
620 yaz-client: show may XML format records. Command show followed by 'format'
621 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
624 src/stemmer.c: Avoid using unnamed union. It is not supported by some
627 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
630 Update yaz.spec to operate on both SLES11 / Centos 5.5.
632 RPM: Release includes 'indexdata' name. Use indexdata in release name so
633 this package can be distinguished from other vendors.
635 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
636 as determined by configure
638 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
640 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
641 returns no error and no record, the present request is considered
642 partial (only a subset of the records could be returned by backend), and
643 so it is appropriate to set Present Status to partial-4.
647 Move yaz-config man pages to section 1.
649 More documentation about Solr.
651 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
652 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
653 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
654 peers on some Linux systems. However, in general that does not work
655 so YAZ can not rely on that to work. Debian changed behavior in this
656 respect from Debian lenny to Debian squeeze (still testing as of Oct

660 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
664 Fix yaz-config output: echo_source not set correctly by configure.
668 Solr Web Service support for yaz-client and ZOOM.
670 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
672 --- 4.0.12 2010/08/17
674 Z39.50 facet support. Facet specifications are passed for search in
675 other-information with ASN.1 as defined in facet.asn and OID
676 .10.1000.81.5 . Facets are expressed as an Attribute list as known
677 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
678 3 is limit (number of entries to get in response). yaz-ztest returns
679 dummy facets if a client asks for them.
681 --- 4.0.11 2010/07/09
683 CCL fixes: bug 2895 and bug 3539.
685 GR1-display: add comma in display - was removed by mistake in
688 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
690 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
692 --- 4.0.10 2010/06/18
694 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
695 result set from a connection. The result set will be on its own
696 thereafter; no operations on it will perform retrievals from a target.
697 Only cached copies are returned.
699 ZOOM C:fix case for HTTP servers responding with Connection:close.
700 Ensure that if there is a current task it is resumed (like fetching
701 more records in a result set) . Bug #3484.
703 PQF parser: use odr_atoi for Odr_int (not atoi)
705 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
706 values that contain any non-digits are treated as string attributes
707 (previously decoding only checked for leading character ([0-9]). PQF
708 encoding: attribute string values are not surrounded by double-quotes.
712 New utility for managing threads - thread_create.h.
714 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
715 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
716 but YAZ' implementation do.
718 Fixes for yaz_cond-functions on Windows 7.
720 DLL export more symbols.
722 zoomsh: show record do NOT render opac.
724 Remove *.la files from Debian and RPM packages.
728 Debian package libyaz-dev depends on libgnutls-dev again (was
729 removed in YAZ 4.0.6, but due to Libtool it is still needed
730 even though yaz-config do not list libgnutls libs).
732 ZOOM: Use only one WRBUF for returning string results for
733 ZOOM_resultset. Reduces memory usage for ZOOM in general.
735 ZOOM: ZOOM_connection do not use a shared pointer to
736 ZOOM_resultset after ZOOM_resultset is destructed by
737 user. Reverts to YAZ 4.0.4 behavior.
741 record-conv: fix problem with at least one XSL conversion -
742 due to probably incorrect usage of XML XSL documents.
746 Fix yaz-config for static mode and the use of SSL (gnutls).
750 Forward decl timeval struct in mutex.h and gettimeofday.h.
752 yaz-config: fix 'static' mode linking.
756 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
757 are wrappers for pthreads or Windows. For Windows these are put in
758 a separate DLL: yaz_cond4.
760 libyaz.la (whole source) is compiled with thread. If thread support
761 is enabled enabled, all source of YAZ is compiled with treading support.
762 This allows core utilities such as yaz_log to use thread facilities.
763 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
764 thread utilities. This commit moves mutex utilities (mutex.c) from
765 libyaz_server.la to libyaz.la.
767 yaz-json-parse displays leading text until error.
771 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
772 patch from Giannis Kosmas.
774 SRU: no longer URL encode SRU database. The URL for an SRU server is
775 a URL and such is alreeady encoded - at least when given with leading
776 http:// or https://. This reverts behavior to YAZ 3.0.50.
778 Support for new MARC XML notation TurboMARC which like MARCXML is a
779 complete representation of MARC/ISO2709.. This one, however, is more
780 compact and allows for faster processing with XSLT. TurboMARC can be
781 used in the marcdisp.h API, from the yaz-marcdump utility and from
784 yaz-ztest can be configured - via the database - to perform certain
785 delays when it performs operations search, present and single record
786 fetch. This allows testers to make yaz-ztest act as a real or even slow
787 Z39.50 server. Refer to the yaz-ztest man pages for details.
791 wrbuf_destroy allows NULL WRBUF passed to it.
793 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
795 Add ZOOM_connection_close.
797 No fixed size buffers for ZOOM shell - bug #3257.
799 tstodr: make it work on s390 platform.
801 New icu iterator-functions. The new icu_iter-functions makes it possible
802 to use ICU chains from many threads.
804 yaz-client: better syntax check for show command.
808 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
811 New simple local-file XML include facility which allows file glob-patterns.
812 Refer to yaz/xml_include.h.
814 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
817 ZOOM_record_get supports new parameter "format" which makes it format XML
820 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
821 JSONText in ECMA-262) is JSONValue, not JSONObject.
825 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
826 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
828 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
829 POSIX/Unix builds .so with major version 4.
831 Remove old LOG_-defines from log.h. They have been obsolete and
832 undefined by default for the last 5 years.
834 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
836 GFS: Remove socket (int *fd) from search_rr handler. The socket
837 descriptor ptr is a facility that allowed a search handler to supply
838 a socket which would serve as a callback - when search was complete.
839 This facility has now been in use for years.
841 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
842 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
843 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
844 returns 'const char *' rather than 'char *. The returned string is
845 read-only and should not be modified by applications. COMSTACK cs_close is
846 now a void function - it no longer returns int. No applications check for
847 the value and the implementations has always returned 0.
849 ZOOM: use size_t for scan hit counts and str size. Functions
850 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
851 occ (hit count) and len (string length) are now of type size_t pointer
852 rather than int pointer. This is to be able to represent large hit counts
853 and to also just to use the proper type for string length (strlen result).
855 New JSON parser. Refer to include/yaz/json.h .
857 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
858 Used to be int in some cases. Many wrbuf_-functions used to return an int
859 indicating some length.. These return values were never used. And so they
862 ODR: odr_malloc, odr_total now takes size_t for size.
864 clone_z_type: fix leak; occurred for encoding failures.
866 --- 3.0.52 2009/12/03
868 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
869 bug was introduced in 3.0.51.
871 --- 3.0.51 2009/12/02
873 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
875 tcpip comstack: fix leak for getaddrinfo.
877 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
878 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
879 Decoding of SRU "path" database is performed by private function
880 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
881 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
883 yaz-client: honor base command for SRU. Change when database setting
884 is applied for SRU and ensure it is kept when a connection is reset.
885 Change also the way errors are displayed or SRU (decoding of packages).
887 --- 3.0.50 2009/11/02
889 Add support for extra request / response data for SRU codecs and GFS.
890 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
891 for extra data response buffer and length. For the GFS, both request
892 and response data (XML) is carried in extra_args and extra_response_data
893 for the search handler. Patch by Ko van der Sloot.
895 ZOOM: For queries that cannot be converted to the specified rpnCharset,
896 ZOOM now returns a diagnostic on the client-side ('invalid query' /
897 10010). This fixes bug #2113.
899 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
900 cmdfile included a 'quit' command that would result in a memory violation.
902 --- 3.0.49 2009/10/01
904 Make a number of functions defined in xmlquery.c static. These have
905 never been declared in a public header file (yaz/xmlquery.h) and was
906 made public by mistake.
908 Improve speed of character conversions (iconv utilities). This makes
909 conversions from MARC-8 faster.
911 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
912 unless type desired is "raw". This will prevent type "xml" from
913 returning ISO2709 .. Which obviously can not be XML parsed.
915 Fix memory leak in ZOOM that would occur if option apdulog was used
916 on a re-used connection.
918 Frontend server logs HTTP requests.
920 Frontend server now sends Z39.50 close when it times out (sesssion has
921 been idle for too long). Versions 2.0.30 and earlier also sent close.
922 But due to a mistake this was disabled in all versions after that, i.e.
923 the server would just close the socket immediately.
925 yaz-client emits a better message when receiving an unrecognised
926 userInformationField.
928 Skip zero-length subfields when decoding ISO2709. This rare case happens
929 if a record has two FS characters in a sequence. Without this patch
930 there would be a reference beyond char array in using_code_len fragments
933 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
935 --- 3.0.48 2009/08/28
937 The show command offered by the zoomsh command now takes a 3d optional
938 parameter type which is what is passed to ZOOM_record. If the type
939 argument is omitted, "render" is used.
941 RPN to CQL conv may use USE string attributes (bug #2978).
943 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
945 --- 3.0.47 2009/07/08
947 Function yaz_xml2query allows a diagnostic element in the PQF XML
948 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
949 code and additional info respectively.
951 The BER BOOLEAN is now the integral type Odr_bool which still happens
952 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
953 typedef'd to Odr_int. This is still an integral 'int', but it may be
954 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
955 ASN-1 compiler as well as programs has been updated to use the new types.
957 --- 3.0.46 2009/06/08
959 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
960 only the bibliographic record was rendered. For type=opac, an OPAC
961 record is only returned if it is present.
963 iconv: small fix for encoding of advancegreek.
965 yaz-client: avoid double display of SRU/SRW records (bug #2798).
967 yaz-client: option auto_reconnect=on really reconnects.
969 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
971 server: avoid null ptr ref for for yaz_poll errors.
973 build: fix RPM build for RHEL 5.3.
975 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
977 --- 3.0.45 2009/03/31
979 Fixed bug #2709: TCP connect returns Invalid argument.
981 Fixed compilation for mingw.
983 Honor charset for raw records (ZOOM_record_get).
985 Fixed use of errno for threaded mode that was seen on Solaris 10.
987 Fixed argument passing with blanks in value for Windows Service.
989 Disable YAZ' own log rotate by default (no 1 GB limit).
990 The variable l_max_size which specifies the log file limit is set to 0
991 (DISABLED): This is due to the fact that YAZ is most often deployed using
992 logrotate. Also YAZ can not perform log rotate because of unsufficient
993 permissions (setuid).
995 --- 3.0.44 2009/02/17
997 List supported encodings in man page for yaz-iconv.
999 Fixed missing SSL libs for --libs output
1001 Re-established OID record syntax application-xml. Nobody should use it
1002 but we don't want to change soname because of this symbol being absent.
1004 --- 3.0.42 2009/02/02
1006 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1008 Added member named_result_sets for init handler struct for the GFS. This
1009 allows a server to disable named result sets.
1011 Removed OID record syntax application-xml.
1013 Added support for rule-based transliterator for ICU wrapper of YAZ.
1015 Fixed bug #1902: yaz-icu XML output.
1017 Make YAZ checks Emacs friendly.
1019 BITSTRING value shows value. Bug #2346.
1021 ISO2709 decoding: skip control characters from indicator data.
1023 Omit sort key by default in yaz-icu's output.
1025 Allow combined single char options (again) for YAZ' options function.
1027 Utility yaz-marcdump got option to display YAZ version (-V).
1029 Allow YAZ to use ICU 3.4.
1031 Added new ICU test case which illustrates removal of diacritics.
1033 --- 3.0.41 2008/12/29
1035 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1037 --- 3.0.40 2008/12/29
1039 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1042 Fixed bug #2352: yaz-marcdump crashes for certain record.
1044 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1046 Added support for Danmarc2 to UTF-8 conversion.
1048 Added support for ISO5426 to UTF-8 conversion.
1050 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1051 implementation version.
1053 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1055 --- 3.0.38 2008/11/10
1057 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1058 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1060 ZOOM C now interprets databaseName option for ZOOM connection as path
1063 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1065 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1067 Dummy Libxml2 types no longer defined in headers of YAZ'.
1069 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1072 --- 3.0.36 2008/09/26
1074 Various ODR chapter fixes.
1076 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1078 Added missing source for Windows compilation, mutex.c.
1080 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1082 For SRU connections in ZOOM all records up to "count" are now fetched.
1084 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1085 in Windows due to bad error handling for Libxml2.
1087 Added facility for sending arbitrary records (ASN.1 any) using
1088 ZOOM C's Extended service update. Patch by Sam Reynolds.
1090 New options for ZOOM C's connection, logapdu which makes ZOOM log
1093 --- 3.0.34 2008/06/18
1095 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1097 --- 3.0.32 2008/06/12
1099 Fixed memory violation that could occur when decoding UTF-8. This bug
1100 was only present in 3.0.30 of YAZ.
1102 --- 3.0.30 2008/06/06
1104 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1105 GNU TLS is used by default (if found).
1107 yaz-ztest returns OPAC records if a client asks for OPAC.
1109 Improved speed of MARC-8 encoding.
1111 Added support for lossy and loss-less MARC-8 encoding.
1113 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1115 Added new Windows Service wrapper (sc).
1117 yaz-client's itemorder command may now send a file.
1119 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1121 Added new function yaz_log_xml_errors.
1123 Allow (but warn) unknown XML attributes in MARCXML parsing.
1125 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1127 The UTF-8 to MARC-8 conversion now uses a different set of characters
1128 for Greek symbols. Bug #2120.
1130 --- 3.0.26 2008/02/21
1132 Added yaz_daemon (daemon.h).
1134 Fixed bug #2068: pkg-config trouble
1136 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1138 --- 3.0.24 2008/01/28
1140 Document --with-xml2 option.
1142 Added OPAC XML XSD (etc/opacxml.xsd).
1144 Allow glob mask for name attribute in retrieval element for the
1145 generic frontend server's retrieval facility.
1147 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1148 except POLLIN/POLLOUT.
1150 Fixed error handling in cs_listen. Bug #2037.
1152 --- 3.0.22 2008/01/20
1154 Fixed version in yaz/yaz-version.h.
1156 Fixed bug #2027: Crash when closing connection.
1158 Changed configure so that ICU support is only enabled if only ICU
1159 and Libxml2 is available (because the ICU chain is XML based).
1161 --- 3.0.20 2008/01/15
1163 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1164 is built. Only this DLL depends on the ICU runtime.
1166 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1167 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1169 Changed license of CCL module to 'Revised BSD'. After consultation with
1170 remaining members of the original EUROPAGATE consortium, we are re-issuing
1171 the CCL module without a separate license. The software was developed by
1172 Index Data as part of a research project. The special license was included
1173 to help feed usage information back to the project consortium to support
1174 project evaluation. At this time, the project consortium has long-since
1175 disbanded, and the majority of the original principals have retired. At the
1176 same time, we have significantly modified the software during the following
1177 years, to the point where very practically no original code remains. To
1178 simplify re-use of the software, we have contacted those members of the
1179 consortium who could be reached, and agreed to re-issue the module as a
1180 proper part of the YAZ package.
1182 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1184 CQL closer to being version 1.2 compliant. CQL also allows free-form
1185 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1188 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1189 bug could make Extended services handling crash in the ZOOM layer. This
1190 bug was only present in YAZ 3.0.18.
1192 --- 3.0.18 2007/12/19
1194 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1197 yaz-marcdump reads and writes collection wrapped records.
1199 Handle OPAC for record conversion module.
1201 Fixes for ICU wrapper.
1203 Allow ICU libs to be controlled with --with-icu .
1205 --- 3.0.16 2007/11/12
1207 Added yaz_poll which is a wrapper for select/poll. When poll is available
1208 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1209 sockets to be in use.
1211 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1212 functionality through an XML based configuration (ICU chain). This system
1213 is useful for search facilities such as Pazpar2 and Zebra that needs to
1214 perform tokenization of indexed material. The ICU code in a separate
1215 library libyaz3_icu.a.
1217 Added HTTP tunnel facility for COMSTACK, bug #1752.
1218 This is a facility that allows a Web proxy, such as squid, to tunnel
1219 Z39.50 traffic. This facility is "transparent" to must applications
1220 using YAZ. It's enabled by using pseudo transport connect: followed by
1221 the proxy address, followed by command, then follwed by he regular
1222 "virtual" addresss. For example,
1223 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1225 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1227 --- 3.0.14 2007/09/21
1229 Fixed bad memory reference in ZOOM_record - cuased by member not being
1230 initialized. This was a problem only in YAZ 3.0.12.
1232 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1233 fields were not removed.
1235 Changed the way C code is generated from codetables.xml. Made a MARC-8
1236 conversion trie for each characterSet section rather than codeTable.
1237 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1238 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1240 --- 3.0.12 2007/09/12
1242 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1243 from ZOOM_record_error).
1245 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1247 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1249 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1251 Better SRW-to-Bib-1 diagnostic mapping.
1253 ZOOM C and yaz-client announces SRU version 1.2 by default.
1255 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1258 Fixed in yaz_sru_decode to allow other version than 1.1.
1260 --- 3.0.10 2007/08/22
1262 Added support for SRU scan for ZOOM.
1264 Added support for the use of the older versions or Extended Service
1265 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1266 set to the version , 1=first, 2=second, 3=third. The third version is
1267 what ZOOM C has used so far. And that, obviously, is the default.
1269 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1270 therefore in Zebra and in SimpleServer-based applications). The new
1271 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1272 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1273 which is passed into the back-end search callback function.
1275 Added support for HTTP Basic authentication in clients: the SRU/W
1276 codec encodes the username/password elements of the PDU structure
1277 appropriately, and these may be set using the "user" and "password"
1278 options in ZOOM-C applications (the same options that are used for
1279 Z39.50 authentication).
1281 --- 3.0.8 2007/06/25
1283 Fixed bug #1208: SSL appears to be broken in ZOOM.
1285 Fixed bug #1206: Libxml2 include path weirdness.
1287 Added oid_name_to_dotstring.
1289 Allow elementSetName to be specified for ZOOM C record update.
1291 Allow waitAction to be specified for ZOOM C based for Extended Services.
1293 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1294 syntax OID. Bug introduced in YAZ 3 series.
1296 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1298 --- 3.0.6 2007/06/06
1300 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1301 directory. yaz-client now reads commands from file given by option -f
1302 if specified; then tries to read .yazclientrc in current directory.
1303 Failing that, it reads .yazclientrc from user's home directory.
1305 Added support for correlationInfo Note and ID for Record Update via
1308 Added yaz-client command querycharset which specifies character set for
1309 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1310 (termListAndStartPoint).
1312 Charset ISO5428:1984 is an alias for ISO5428-1984.
1314 Implemented a way to perform scan in a result set using Z39.50. This
1315 is achieved by attaching the result set name in the characterInfo
1316 (type InternationalString) of OtherInformation in the Scan Request PDU.
1317 The result set is identified in the otherinformation by the new OID:
1318 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1319 This allows for scan in result set and faceted search . Zebra did some
1320 of this in the APT term using attribute type 8 and value being result
1321 set. Using the OtherInformation approach for this is cleaner and easier
1322 to work with in proxies and the like. This facility can be used in
1323 yaz-client using new command setscan which takes a result set as first
1324 argument, start position (APT) as second.
1326 Changed decoding of SRU XML packed records to deal with servers that
1327 have recordData with XML data with multiple root nodes. Also make
1328 comparison for recordPacking case insensitive. Again, one server
1329 returns "XML" where others return "xml".
1331 For SRU responses allow Content-Type application/xml as well as text/xml.
1333 --- 3.0.4 2007/05/21
1335 Fixed bug in character set conversion of BER strings. Bug introduced
1338 --- 3.0.2 2007/05/08
1340 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1342 For OID class, use oid_class consistently.
1344 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1347 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1348 character set for bibliographic information interchange". By Giannis Kosmas.
1350 Added documentation on new OID API.
1352 --- 3.0.0 2007/05/02
1354 Changes to generic frontend server interface: added new member
1355 'query_charset' for bend_initrequest structure. A backend init handler
1356 should set this member to its native character set for query terms.
1357 When defined, the frontend server logic will announce this character set
1358 to a client if the negotiationModel bit is set by the client. All server
1359 implementors are encouraged to specify this. If a backend server does not
1360 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1362 Added CCL utility to remove terms (stop words) from resulting RPN
1363 tree. This is handled by functions with prefix ccl_stop_words_ .
1365 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1366 terms in RPN queries.
1368 Clean-up the CCL API. Moved some internal structures from ccl.h to
1369 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1370 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1371 This is replaced by ccl_parser_find_str which takes a string instead.
1373 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1374 libyaz.la is the core of YAZ except the generic frontend server and
1375 does not depend on POSIX threads anymore. libyaz_server.la is the
1376 generic frontend server facilities and uses POSIX thread functionality
1377 if available. The libyaz.la no longer depends on POSIX threads because
1378 the number of global structures is limited. NMEM no longer re-uses blocks
1379 between threads ; it simply free's memory immediately but allocates in
1380 "large" chunks as usual. We don't expect any performance penalties
1381 because of this. The yaz_log system is still using a global log_level so
1382 caution must be taken when modifying it with yaz_log_init_.. +
1383 yaz_log_mask_str. This, however, should not cause any trouble because
1384 these functions are called during initialization of application code
1385 anyway. `yaz-config --libs server` returns libs for server applications;
1386 `yaz-config --libs` returns libs for non-server applications.
1388 New OID database - with public definitions in oid_db.h. Removed old OID
1389 database including the head oid.h and definitions such as enum oid_value
1390 and struct oident. The new OID database uses the same string names as
1391 before but the 'protocol' is gone. There are now only two representations
1392 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1393 converts from string to OID; functions with prefix yaz_oid_to_string
1394 converts the other way.
1396 Change to emit_term() in CQL-to-PQF query translation: when a term has
1397 the /regexp relation modifier, do not process it for leading and
1398 trailing "^" and "*", which have quite different meanings in regular
1401 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1402 write handlers no longer carries a 'last' parameter. This will make
1403 yaz_iconv flush "less" characters. A flush is performed by call to
1404 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1406 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1407 removed, because function yaz_query_to_wrbuf does the same.
1409 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1410 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1412 Deprecated MARC utility functions removed.
1414 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1417 Branch split: YAZ_2_1_55_branch
1419 --- 2.1.54 2007/03/16
1421 Fix to ZOOM-C so that transparent reconnection is properly handled on
1422 connections that are in asynchronous mode.
1424 Fixed compilation on OpenBSD 4.0.
1426 Large strings in GRS-1 records are now properly displayed in yaz-client.
1428 Added character conversion support for "advancegreek"; based on patch from
1431 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1432 sequence is met. Before the error was not set so it would be unknown.
1434 Adjust yaz-marcdump MARC reader so that it skips until record separator
1437 --- 2.1.52 2007/03/07
1439 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1440 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1441 fd_set structure used as a bitmask for the FDs to be selected on.
1443 Using ACX_PTHREAD macro to check for POSIX threads.
1445 Fixed have-vsnprintf check.
1447 --- 2.1.50 2007/02/23
1449 Fixes for configure on BSD. Bug #900.
1451 Added snprintf/vsnprintf wrappers for systems that don't have
1452 limits (heavens forbid).
1454 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1455 created before all previous tasks were completed and removed from the
1456 task queue, the new task could be removed by a mistake.
1458 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1460 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1462 Fixed bug #832: Problem with MARC/charset in yaz-client.
1464 Fixed bug #668: save command line history for yaz-client.
1466 Fixed bug #830: pkg-config support.
1468 --- 2.1.48 2007/01/23
1470 Extended ZOOM result set options with two options that may be read by
1471 a client: resultSetStatus and presentStatus with values as specified for
1473 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1475 Fixed bug #827: Using SSL fails on Debian etch.
1477 Fixed bug #826: Weird looking chars for set of MARC records.
1479 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1480 that is treated as an ItemOrder with itemRequest being an XML document
1481 external. The value of "doc" is the content.
1483 Extended the GFS search facility. New member of bend_search_rr
1484 'estimated_hit_count' signals that hits is known to be an estmate
1485 (higher or lower than real hit count). New member 'partial_resultset'
1486 signals that the search was partial (hit count is lower or equal than
1487 real hit count). For Z39.50, the information is stored in resultSetStatus
1488 member of SearchResponse APDU. For SRU, the information is signalled
1489 via SRU diagnostic 59: "Result set created with valid partial results
1492 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1494 --- 2.1.46 2007/01/13
1496 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1498 Added ZOOM_connection_peek_event.
1500 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1501 the following new functions:
1502 ZOOM_event_nonblock, ZOOM_connection_process,
1503 ZOOM_connection_get_{socket,mask,timeout},
1504 ZOOM_connection_fire_event_{timeout,socket}.
1505 The existing blocking event handler, ZOOM_event, is a wrapper for the
1506 + blocking ZOOM_event_sys_{poll,select}.
1508 Implemented function ccl_xml_config which parses XML version of CCL
1509 configuration (bug #798).
1511 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1513 Added timings utility (yaz/timing.h)
1515 --- 2.1.44 2007/01/03
1517 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1520 Fixed bug #779: Rotation of apdu.log fails.
1522 Fixed for character set conversions:
1523 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1524 Honor G1 set in MARC-8 decoding.
1526 --- 2.1.42 2006/12/17
1528 Fixed bug #775: char conversion does not handle Alternative UTF-8
1531 Implemented function yaz_marc_read_line which parses MARC line format
1532 records. There is a wealth of formats out there. So far, this function
1533 reads line records produced by yaz_marc_write_line.
1535 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1536 more generic and easier to remember(!) options: -i format and -o format
1537 which specifies input format and output format respectively - where
1538 format is one of "marc", "marcxml", "line", "marcxchange".
1540 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1541 does not print anything except warnings for records.
1543 For yaz-marcdump, added support for MARC split into files (-s) with a given
1546 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1547 spec, at http://www.loc.gov/standards/sru/record-update/
1548 This has changed the binary layout of the following structs:
1549 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1550 bend_update_rr . Patch by Ko van der Sloot.
1552 Added GFS utility function bend_assoc_is_alive which returns 1 if
1553 association is still alive (client is connected); 0 otherwise (client
1554 closed connection). This allows busy servers to stop working for
1557 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1558 been a separate piece of software. This version of ziffy has been modified
1559 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1561 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1563 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1564 Client code may now interrogate options such as "init_opt_sort" to
1565 find out whether the server claims to support various options.
1567 --- 2.1.40 2006/11/27
1569 Added utilities yaz_{set,get}_esn to set/get element set name from
1572 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1573 of YAZ and has been so since YAZ 2.1.10.
1575 Implemented ZOOM_record_error which returns error information for
1576 record (surrogate diagnostic).
1578 --- 2.1.38 2006/10/31
1580 Updates for SRU Update by Ko van der Sloot:
1581 1. Changed name from "operation" to "action"
1582 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1583 versions in the code, marked as 'backward compatible'.
1584 3. Added diagnostics for SRU Update.
1586 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1588 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1590 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1592 For GFS, fixed problem with SRU diagnostic 'First record position out of
1593 range' being issued for 0 hits.
1595 zoomtst10 part of Windows Build.
1597 --- 2.1.36 2006/10/13
1599 Implemented yaz_filepath_comp which splits a path into file path
1600 components (required by Zebra 2.0.3+).
1602 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1603 BSD inspired license until now so this should not have any real impact on
1604 anybody. See http://www.opensource.org/licenses/bsd-license.php
1606 Fixed bug #687: Missing log lines.
1608 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1611 Fixed bug #689: SRU diagnostics to be added.
1613 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1614 whether a connection is idle (no more work do do).
1616 --- 2.1.34 2006/10/04
1618 Change type of optval from long to int for invocation of setsockopt with
1619 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1621 Added support for specifying the max log file size for the Generic
1622 Frontend Server. The size is given with option -r.
1624 --- 2.1.32 2006/09/21
1626 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1628 --- 2.1.30 2006/09/17
1630 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1633 Fixed bug in Generic Frontend Server that could cause a server to stop
1634 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1636 For the generic frontend server, the maximum record size is used as maximum
1637 size of incoming packages (SRU + Z39.50). The value until was previously
1638 only used in Z39.50 Init negotiation and, later, in a session controlled
1639 sizes of records returned. This is controlled using -k option. It can be
1640 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1642 --- 2.1.28 2006/09/04
1644 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1647 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1649 New option for yaz-marcdump -lpos=value which allows setting a portion
1650 of MARC header to a certain value.
1652 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1654 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1655 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1657 --- 2.1.26 2006/08/15
1659 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1662 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1664 --- 2.1.24 2006/08/08
1666 Fixed MARC ISO2709 encoding routines to deal with character set
1669 Minor changes to GFS logging. Database included in search request log
1672 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1673 cached/multiple records.
1675 Shared libraries are built by default on Unix+configure.
1677 Changed cql2pqf transformation to use a different evaluation order. The
1678 new order is: always, relation, structure, position, truncation, index
1679 and relationModifier. Old order was: always, relation, relationModifier,
1680 structure, index, position, truncation. Note that the the latter ones
1681 override former ones for identical attributes.. The new scheme means that
1682 it is possible to override any existing attribute with a relationModifier.
1683 And also that it is possible to override everything for the index rule
1684 (except the ones listed in relationModifier). No order is perfect but this
1685 one, we believe, covers more real cases.. The "always" should have been
1686 called "default", since the attributes there can be overridden with all
1689 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1690 compilation phase, but also for yaz-config --cflags output. This allows
1691 us to have public headers with Libxml2 stuff in them . It should also,
1692 eventually, make Libxml2 checks redundant in packages using YAZ, such
1695 --- 2.1.22 2006/06/15
1697 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1698 stored in uri, message and details.. Previously diagnostics were stored
1699 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1700 compatibility.. but he's probably the only one affected, so.
1702 Added support for CCL, compiled on the client side, in ZOOM-C. This
1703 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1704 input; the resulting query objects can be used for for searching with
1705 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1707 YAZ' configure searches for OpenSSL by default.
1709 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1710 SL_CTX_use_certificate_file. See
1711 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1712 for more info. Thanks to Ko van der Sloot.
1714 --- 2.1.20 2006/06/02
1716 Bug #600: SRU GET, POST support for yaz-client. Introduced
1717 command 'sru' which selects method SOAP/GET/POST.
1719 Allow missingValueAction to be specified for the sortspec string -
1720 function yaz_sort_spec. By default, the missing value action is null.
1721 Use ! to specify "abort". Use = followed by stringvalue to specify default
1724 Ensured that Present-handler (if defined) is called in GFS before any call to
1725 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1726 searchRetrieve requests.
1728 Documentation for YAZ is now based on the Docbook XML/XSLT using
1729 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1730 is no longer depending on jade/openjade or docbook-to-man scripts.
1731 PDF is no longer part of the distribution - but can optionally be
1732 made using DSSSL/jadetex or FOP.
1734 Added retrieval handling support in Generic Frontend Server to support
1735 conversion between MARC/XML as well as XSLTtransforms. See
1736 etc/yazgfs.xml for an example.
1738 Added Authentication support to Generic Frontend Server in SRU
1739 mode. Authentication using HTTP Basic is supported, as is the use
1740 of 'x-username' and 'x-password' parameters in the request itself.
1742 Added support for a new character set MARC8s identical to MARC8 except
1743 that it converts combined characters to single Unicode characters in the
1744 Latin-1 range (when possible).
1746 --- 2.1.18 2006/04/24
1748 ASN.1 compiler 0.4: generates brief Doxygen file header for
1749 generated .h/.c files.
1751 Utility yaz_iconv now supports conversion to MARC-8.
1753 New facilities for the MARC module. The reading - and writing of
1754 content are separate methods for the yaz_marc_t handle. The following
1755 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1756 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1757 format). Write functions have prefix yaz_marc_write_.. The existing
1758 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1759 available. Removed support for OAI-MARC and simplexml (not the
1760 simplexml from PHP5).
1762 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1763 to be returned for this connection.
1765 --- 2.1.16 2006/03/31
1767 Allow multiple languages and charsets to be specified with
1768 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1769 negcharset iso-8859-1,utf-8
1771 Translation of proximity nodes from CQL into PQF now works.
1773 Moved to automake 1.8, 1.9.
1775 Added function yaz_log_set_handler which allows a log handler to be
1776 installed. This handler will be called for all log messages. Output
1777 to file is also produced; but that can be disabled by passing NULL
1778 fname to yaz_log_init_file.
1780 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1782 For SRW (including GFS), accept application/soap+xml as content-type
1785 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1786 produces NO stylesheet reference even if a default stylesheet is specified
1789 --- 2.1.14 2006/03/14
1791 Updated Windows package to include yazd.dll + yazd.lib for the
1792 Development component.
1794 If the environment variable YAZ_LOG is set, then it is used as a
1795 string indicating the default level of logging to use if not
1796 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1797 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1798 used as before. So, for example, to omit warnings from YAZ logging,
1799 export YAZ_LOG=-warn
1801 cql_transform() now map structure and other attributes before indexes,
1802 so that index-specific structures and other attributes can override
1803 defaults. So now a combination of mapping specifications such as:
1805 index.dc.date = 1=date-modified 4=5
1806 does the right thing.
1808 cql_transform() now also respects the "always" mapping specification,
1809 which establishes an initial set of attributes to be used for all
1810 terms except where overridden by more specific attributes associated
1811 with the index, relation or modifier.
1813 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1814 which mode to use; one of "post", "get" or "soap" (SRW, default).
1816 Fixes for yaz_iconv routines: changed trie-based character set conversions
1817 to use only non-negative values for bit fields due to Sun's C compiler not
1818 supporting negative values.
1820 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1821 sequences where not read correctly. Fix by Rustam Usmanov.
1823 Updated win/makefile to use options, settings which makes things
1824 compile with VS C 2005.
1826 --- 2.1.12 2006/02/01
1828 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1830 In ZOOM socket code, use select instead of poll on MacOSX.
1832 ZOOM-C now support client-side compilation of CQL into RPN that is
1833 sent to the server, enabling CQL to be used against all Z39.50
1834 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1835 ZOOM_query object, and submit it using ZOOM_connection_search().
1836 The CQL-to-RPN translation uses a configuration file, the name of
1837 which must be specified in the Connection's "cqlfile" option.
1839 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1840 function, which takes as its start-term parameter a ZOOM_query object
1841 (which may have had either CQL or RPN set into it).
1844 --- 2.1.10 2005/11/29
1846 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1847 GFS to support this as well. Backend handler, bend_srw_update, does the
1848 update work. Code contributed by Ko van der Sloot.
1850 Allow retrieval of Search Result-1 information in ZOOM by the use of
1851 options that are attached to a result set. ZOOM documentation updated
1854 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1855 UTF-8 conversion. Patch by Raj Patel.
1857 Added option -m to GFS to control formatting of timestamps in log file.
1859 Added 'exit' as synonym for 'quit' in yaz-client
1861 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1862 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1863 for the new members. Patch by Ko van der Sloot.
1865 Added support for SRU POST. It is supported for content-type
1866 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1868 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1869 Instead make the library libyaz.la multi-threaded. Threading as a whole
1870 can still be disabled by configure option --disable-threads. Previosly,
1871 with older GLIBCs there were problems with MT libs under Apache. This
1872 has now been fixed a long time ago.
1874 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1877 CQL module modified to be case insensitive for relations/indexes/operations.
1879 Fixed bug in CQL transform code: incorrect value relationModifieder
1882 Added 'show all' command for yaz-client which retrieves all results
1885 Added new yaz-client, xmles, which takes a (private) OID and
1886 a document to be sent as an extended service request.
1888 Describe new yaz-client commands wait_response and set_auto_wait.
1890 Increase TCP/IP listener backlog from 3 (which I am guessing was
1891 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1892 that the socket will queue as many incoming connections as it's able
1893 to handle ongoing connections. In other words, it will never now
1894 refuse a connection that it would be able to handle merely because
1895 it's not got around to accepting() enough of the pending connections
1896 yet. This is the behaviour anyway under Linux, where the listen()
1897 argument is ignored; but not under BSD and on systems such as
1898 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1899 YAZ-based servers should now be uniform across operating systems in
1902 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1903 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1904 This allows yaz-marcdump to read large MARC batches (>2 GB).
1906 Modified all YAZ source files - except the source which is auto-generated
1907 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1910 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1911 corresponding to the existing *_setl() function. These allow option
1912 values containing arbitrary valuues.
1914 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1915 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1916 except that it returns an indicator of whether or not the sort
1917 criterion was accepted (0 for OK, -1 for invalid).
1919 --- 2.1.8 2005/06/07
1921 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1922 MARC output rather than returning "new" buffer.
1924 yaz-client warns about unknown init options.
1926 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1928 --- 2.1.6 2005/05/24
1930 Added support for SRW sort in Generic Frontend Server. Patch
1931 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1932 sortKeys - or NULL if none is provided.
1934 Fixed bug #307: It was impossible to specify indefinite/no timeout
1935 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1938 Added support for multiple languages and charsets to be specified in
1939 ZOOM. Each charset/language is separated by a blank. If negotiation is
1940 in effect in init-response, Option
1941 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1942 Code based on patch by Vasiliy Osadchuk.
1944 Fixed bug #306: infinite recursion that occurred when calling
1945 yaz_log_level_init as the first call (before other log level or
1948 Fixed bug in scan handling in front end server: if preferred-Position-In-
1949 Response was non-present, a NULL pointer referece was performed.
1951 --- 2.1.4 2005/04/26
1953 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1954 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1955 now defined for all those error codes. So instead of putting 109 in
1956 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1957 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1959 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1962 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1964 Program yaz-client now exits and produces an error message if multiple
1965 Z39.50 servers are specified on the command line (none or one allowed
1968 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1971 --- 2.1.2 2005/03/16
1973 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1975 Fixed bug #272: Preserve spacing for CCL terms.
1977 --- 2.1.0 2005/03/14
1979 Added support for virtual hosts and multiple backend servers for
1980 the YAZ frontend server. The configution is XML based and
1981 support specificition of CQL to RPN mappings and explain information.
1982 See section "Virtual Hosts" in the YAZ manual.
1984 Extended OPAC display utility. OPAC display utility renders
1985 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1986 to supplement yaz_marc_decode_wrbuf.
1988 Fixed a bug in MARC decoder that could caused it to crash for some
1989 invalid MARC records. More diagnostics and warnings where added in
1990 XML output (warnings, etc are stored in comments).
1992 --- 2.0.34 2005/02/08
1994 Fixes for UNIX domain sockets. Bug #261.
1996 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1998 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1999 Added yaz_marc_subfield_str which defines subfield lead string which is
2000 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2001 yaz_marc_endline_str which defines end of fields string used in
2002 YAZ_MARC_LINE format. Default string is newline.
2004 Experimental support for MarcXChange. This format can be produced
2005 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2006 http://www.bs.dk/standards/MarcXchange.xsd
2008 Added yaz-client commands scansize that sets maximum number of
2009 entries to be returned by scan.
2011 --- 2.0.32 2005/01/11
2013 Added support for SRW scan in yaz-client and Generic Frontend Server.
2015 * Added whereInList member to SRW Scan Term.
2017 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2019 Fixed NMEM system to return aligned blocks on the smallest boundaries
2020 that are suitably aligned for all possible types on the particular
2021 architecture YAZ is being built for.
2023 --- 2.0.30 2005/01/04
2025 Fixed numerious warnings that was issued with newer versions of GCC.
2027 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2028 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2031 Make YAZ Generic Frontend Server slightly faster.
2033 Enhance (and reduce) logging for Generic Frontend Server.
2035 Revert YAZ log system so that it flushes every write operation
2036 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2038 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2039 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2040 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2041 will effectively disable old definitions.
2043 --- 2.0.28 2004/11/09
2045 Added yaz_log_time_format which specifies log format using
2048 Added yaz_log_module_level which returns mask for a module. Value
2049 is non-zero mask a if module is enabled; zero if disabled.
2051 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2052 in include/yaz/cql.h.
2054 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2056 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2058 Fixed bug #172: RPM builds does not enable SSL.
2060 Doxyfile.in part of dist. Doxyfile generated by configure.
2062 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2063 are given and the corresponding component does not exist.
2065 Extend CCL documentation in YAZ reference. Describe r=r.
2067 --- 2.0.26 2004/10/01
2069 Fixed MARC->MARCXML conversion to properly deal with
2070 fields, subfields, indicators having non-ASCII characters.
2072 Fixed MARC->MARCXML conversion so that ASCII control characters
2073 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2076 Added YAZ GFS support for conversion from Z39.50 surrogate
2077 diagnostics to SRW surrogate diagnostics.
2079 Bug fix: YAZ GFS did not return schema in explainResponse.
2081 --- 2.0.25 2004/09/30
2083 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2084 now converts recordSchema to elementSetName as well as schema URI.
2086 Fixed bug in COMSTACK that prevented HTTP request packages from being
2089 --- 2.0.24 2004/09/29
2091 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2092 does not require white-space before and after the dash in a range, e.g.
2093 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2096 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2097 due to new GCC removing "redundant" code.
2099 Added yaz-client commands scanpos and scanstep that sets preferred
2100 position and step-size for scan.
2102 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2104 Added CCL utility ccl_qual_buf which parses one or more CCL
2105 spec lines in a buffer.
2107 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2108 of name and value - ignoring empty lines and comments.
2110 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2112 Added odr_get_element_path which returns current element path for an
2113 ODR handle. This utility is useful in error handling or user-defined
2116 Added ODR_PRINT utility odr_set_stream which is is a more generic
2117 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2118 to a write function and pointer to close function. The close function - if
2119 non-NULL - will be called during odr_destroy.
2121 Fixed bug in CCL parser where truncation char was not removed from
2122 right side when truncation=both was in effect.
2124 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2127 --- 2.0.23 2004/08/11
2129 Fix buffer overrun in CQL parser when dealing with proximity (%).
2131 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2132 to UTF-8/UCS conversion is now only based on codetables.xml.
2134 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2136 --- 2.0.22 2004/08/06
2138 Add support for more "commit changes" in ZOOM (uses Extended Services).
2140 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2143 Yet another small fix for configure of SSL.
2145 --- 2.0.21 2004/05/14
2147 Fix SSL libs for configure when --with-openssl=DIR is given.
2149 --- 2.0.20 2004/05/10
2151 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2153 SSL comstack now uses yaz.pem certificate file on server side
2154 by default. Certificate filename can be configured by calling
2155 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2157 Fix bug regarding multiple calls to ZOOM_connection_connect.
2159 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2161 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2162 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2164 ZOOM now allows inspection of X509 peer certificate for verification.
2165 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2167 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2168 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2169 as "modular" but it simplifies things.
2171 Added cs_get_peer_certificate to that returns peer X509 PEM.
2173 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2174 NULL if SSL is unavailable.
2176 Documentation about MARC decoding tools.
2178 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2180 --- 2.0.19 2004/03/30
2182 Rename CHANGELOG to NEWS to follow GNU style packing.
2184 Fix bug with missing initialization of member in init_diagnostics.
2185 This bug affects threaded version of GFS server.
2187 --- 2.0.18 2004/03/20
2189 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2192 Ensure zlib.dll is packed with Windows install.
2194 --- 2.0.17 2004/03/17
2196 Fix encoding of xsd:string to use text instead of CDATA.
2198 Fix endless loop in CQL parser with unbalanced ".
2200 Use a more compact way to store MARC-8 conversion tables.
2202 --- 2.0.16 2004/03/16 Debian only
2204 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2207 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2212 --- 2.0.15 2004/03/01
2214 Another fix for decoding of XML packed records.
2216 --- 2.0.14 2004/02/25
2218 Fixes for Chunked encoding. White space not ignored after length spec.
2220 Update NS and use default NS for SRW diagnostic elements.
2222 --- 2.0.13 2004/02/23
2224 Implement ZOOM_resultset_cache_reset which resets record cache.
2226 Implement ZOOM_resultset_sort which sorts a result set.
2228 Implement chunked HTTP transfer.
2230 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2232 --- 2.0.12 2004/02/16
2234 Added member 'schema' to bend_explain_rr structure so that backend
2235 can specify explain record identifier. Defaults to Zeerex 2.0.
2237 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2239 --- 2.0.11 2004/02/16
2241 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2244 Added init command for yaz-client which sends "extra" init request.
2246 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2247 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2249 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2251 Make ZOOM error code for "invalid query".
2253 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2255 --- 2.0.10 2004/02/05
2257 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2260 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2262 Added option -p <file> to make Generic Frontend Server to write PID file.
2264 Added option -D to put Generic Frontend Server in background on its own.
2266 Make ZOOM C recognize option "password". If unset, "pass" is used
2267 (for backwards compatibility).
2269 Fixed a bug in Generic Frontend Server that could make it crash if a
2270 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2273 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2274 Must be issued before open, in order to be in effect.
2276 --- 2.0.9-6 2004/01/12 Debian/Windows
2278 Make the SRU server more picky WRT unknown params, etc.
2280 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2282 New YAZ client command, options, that sets Z39.50 options.
2284 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2285 options from a string of tokens (one token for each option bit).
2287 Update SRW diagnostic code messages.
2289 --- 2.0.9-5 2004/01/07 Debian/Windows
2291 Handle user defined stylesheet for SRW/SRU.
2293 --- 2.0.9-4 2004/01/06 Debian/Windows
2295 Fix bug in decoding of Content-Length.
2297 --- 2.0.9-3 2004/01/06 Debian/Windows
2299 Fix a bug with decoding of XML packed records.
2301 --- 2.0.9-2 2004/01/05 Debian only
2303 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2305 Fix bug in SRW/SRU diagnostics decoding.
2307 --- 2.0.9 2004/01/05
2309 Fixed bug in Generic Frontend Server which could drop records exceeding
2310 preferred message size. Reported and fixed by Irina Dijour.
2312 Fixed calculation of package size for structured records in Generic
2313 Frontend Server. Reported and fixed by Irina Dijour.
2315 Fixed namespace for SRW/SRU diagnostics.
2317 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2319 --- 2.0.8 2003/12/22
2321 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2322 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2325 CQL changes to reflect recent changes to the specification:
2326 * Documentation talks about context sets instead of index sets.
2327 * Documentation talks about indexes instead of qualifiers.
2328 * The CQL-to-PQF transformer's configuration file now uses
2329 "index.set.name = <attributes>" instead of the old form
2330 "qualifier.set.name = <attributes>". (Both forms are still
2331 understood but the latter is deprecated.)
2332 * CQL terms with no explicit index specified are now interpreted as
2333 cql.serverChoice instead of srw.serverChoice (which of course
2334 behaves exactly the same.)
2336 --- 2.0.7 2003/12/16
2338 MARC conversion can now generate ISO2709 output in another
2339 character set. yaz-marcdump uses this facility if you invoke it
2342 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2343 functions from there can be used from C++.
2345 --- 2.0.6 2003/12/04
2347 Frontend server now transfers memory from decoded packages to stream
2350 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2351 references to show up.
2353 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2354 the ZOOM Abstract API. The older names for the same options are still
2355 also supported for the benefit of old applications.
2357 ZOOM-C supports "implementationId" and "implementationVersion" options
2358 to go along with "implementationName". These allow the user code to
2359 specify identification strings to be sent to servers.
2360 Add OID for the new ExtLite attribute set.
2362 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2363 as requested/supplid by Ere Maijala <ere@atp.fi>
2365 For generic frontend server, reverse the order of
2366 "toolkit-supplied / application-supplied" strings sent as implementationId,
2367 Name and Version. Also, remove the spaces around the slash. This brings
2368 the GFS in line with the behaviour of ZOOM-C on the client side.
2370 Add function ZOOM_scanset_display_term.
2372 yaz-client shows scan displayTerm if present.
2374 Utility yaz-iconv is now installed by default along with the man page
2377 Extend configure check for OpenSSL to use pkg-config where available (such
2380 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2381 server to specify uid/gid/mask for socket using the format
2382 unix:[user=uid,][group=gid,][umask=mask,]file=path
2383 If file= is omitted the existing format is assumed, e.g.
2385 in which case the mask is 0666 (rw for everybody).
2387 Major restructure of YAZ source. All source in libyaz is in src directory.
2388 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2389 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2391 Added man page for utility yaz-marcdump (used to be called marcdump).
2392 yaz-marcdump is installed by 'make install'.
2394 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2395 of incoming package failed.
2397 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2399 Change prototype of odr_perror: add const to message string.
2401 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2403 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2404 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2405 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2406 DNS lookup. There should not be any compatibility problems with this
2407 assuming that blocking=1 or 0 is used.
2409 Fix bad reference in UNIX comstack in function cs_addrstr.
2411 Fix for compilation on AIX.
2413 The generic front-end server (server/seshigh.c) now supports returning
2414 Init diagnostics to the client in User-information-field, in
2415 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2418 --- 2.0.4 2003/09/04
2420 Allow any CQL relation (not just all,any,exact,scr).
2422 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2423 that features the same UI.
2425 Implemented command update0 in YAZ client which is equivalent to
2426 update but uses old of Ext Update ASN.1.
2428 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2429 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2430 Previously no OID was used for this info.
2432 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2433 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2434 returns 'malformed search term' otherwise.
2436 SortResponse member resultCount now set to NULL in sort handler of
2439 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2442 Add three new utility functions for translating OIDs between various
2443 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2444 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2445 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2446 char *oid_to_dotstring(const int *oid, char *oidbuf);
2447 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2449 Reverted modifications for ES Update definition for z_IU0Update
2450 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2451 is back to YAZ 2.0.2.
2453 String value attributes for CCL parser.
2455 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2456 which their FirstSearch server returns in Init responses, sometimes
2457 carrying useful diagnostic information when Init fails. This has the
2458 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2459 "z39.50/oclcui.asn", where its definition is somewhat different from
2460 what OCLC document on their web-site, as required to interoperate with
2463 Support for anonymous authentication in yaz-client. Use the command
2466 * Fix the OID of the Index Data-local "admin" Extended Service from
2467 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2468 the 1000, which indicates a locally-defined OID, was a mistake.
2470 --- 2.0.3 2003/06/20
2472 Fix CCL directive @case handling so that it affects string match for
2473 both CCL keywords and qualifiers.
2475 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2476 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2477 Decoder has been updated with ASN.1 changes as listed in
2478 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2479 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2480 z_IUUpdate, remains unchanged.
2482 ZOOM_record_get may now return a record in a specific character set.
2483 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2484 "from" is the character set of record as returned by target. "to" is
2485 the character set to be returned. If omitted, "to" is UTF-8.
2487 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2489 New ODR utility, odr_getelement, which returns name of element for
2490 which encoding/decoding failed.
2492 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2493 in cases where a required element was omitted.
2495 Bug fix: some MARC8 sequences were not converted.
2497 New ZOOM option "step" which specifies number of records to be
2498 retrieved in one chunk. Used in conjunction with "start" and "count".
2500 SRW support for yaz-client. Use scheme http: to use it, e.g.
2503 yaz-client no longer does (un)intelligent character set conversions
2504 by default. Can be enabled with charset and marc_charset commands.
2506 xmalloc trace fix for 64-bit systems such as DEC alpha.
2508 Solaris 2.6 compile fix.
2510 New function, cql_strerror() translates SRW error codes, as returned
2511 by cql_transform_error(), into human-readable English strings. Used
2512 in yaz-client diagnostics when appropriate.
2514 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2515 converts it into a type-1 query which is sent to the server. This
2516 makes CQL available for use with all Z-servers, as opposed to the tiny
2517 minority that can handle CQL queries themselves.
2519 --- 2.0.2 2003/04/28
2521 New Debian package layout similar to the Redhat Package layout.
2523 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2524 and search result respectively.
2526 --- 2.0.1 2003/04/25
2528 Redhat package is now several packages: libyaz (runtime libraries),
2529 libyaz-devel (development and documentation, and yaz (utility programs).
2530 Package spec file by Morten Bogeskov.
2532 New member 'schema' in struct bend_fetch_rr which the name of requested
2533 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2534 handler MAY set this to reflect the schema of the returned record.
2536 New member 'display_term' in struct scan_entry. GFS now sets member entries
2537 and allocates scan entries to be filled by user scan handler. In previous
2538 version, entries member was allocated by the scan handler. That still works,
2539 but the GFS will ignore member display_term - assuming it was NOT set by
2540 the handler. The fact that the GFS now allocates the entries both allows
2541 for new members and makes a scan handler easier to write.
2543 Fix CQL lex buffer overflow.
2545 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2546 SRU default recordPacking is string.
2548 SRU protocol support for frontend server.
2550 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2552 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2554 Added scan for the ZOOM shell (zoomsh).
2558 * String Identifers for Schemas (Amendment 5).
2559 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2560 Old definition for schema
2561 Odr_oid *schema; /* OPT */
2566 Z_InternationalString *uri;
2567 #define Z_Schema_oid 1
2568 #define Z_Schema_uri 2
2571 * resultCount parameter to Sort Response (Amendment 1).
2572 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2574 Support for SRW 1.0 over HTTP. This is an optional feature and
2575 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2578 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2579 on the same port. SRW SearchRetrieveRequests are mapped
2580 to bend_init,bend_search,bend_fetch,bend_close.
2582 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2584 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2585 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2587 ZOOM connections are SRW based if schem http is used for hostname
2588 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2589 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2591 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2592 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2593 distance=n, order=true/false, relation=le, prox unit=word. If
2594 n is omitted, distance 1 is used.
2596 Fixed problem with C compiler include path in wrong order.
2598 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2599 on Solaris. Patch from Ko van der Sloot.
2601 New MARC decode API. All new functions operate on a yaz_marc_t
2602 handle. The most important new functions are: yaz_marc_create,
2603 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2604 decode and destroy respectively. Decoder can produce formats
2605 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2606 include/yaz/marcdisp.h.
2608 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2609 to UTF-8, UCS-32, wchar_t or Latin-1.
2611 * Prototypes for yaz_iconv_-functions moved to separate header
2612 include/yaz/yaz-iconv.h.
2614 Make a few private functions 'static' in unix.c. This prevents
2615 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2617 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2618 are set when Init Response is received.
2620 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2621 but returns diagnostic set as well.
2623 New function yaz_strerror which is a portable wrapper for
2624 strerror/strerror_r/GetLastMessage.
2626 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2627 is returned for MARC. If type is "oai", then OAI MARC is returned.
2629 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2632 --- 1.9.2 2002/11/26
2634 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2636 Fix bad race conditions on SIGTERM and terminate gracefully in
2639 Move retrieval (data1) module to Zebra since nobody seems to be
2642 Add GRS-1 render for ZOOM using same format as yaz-client.
2644 --- 1.9.1 2002/10/05
2646 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2648 Fix broken ESpec handling in data1 module.
2650 SGML reader parses comments and makes them part of the data1 tree.
2652 Added several type casts so that YAZ compiles as C++ code.
2654 ZOOM didn't handle PDU encoding failures properly.
2656 Added more Bib-1 diagnostics (approved extensions).
2658 GNU configure: better check for iconv.
2660 More portable use of accept, getpeername. Check for socklen_t. Use
2661 int/size_t if socklen_t is not defined.
2665 PQF parser rejects bad queries - including those with extra
2666 characters in them. PQF parser used to silently ignore that.
2667 Cleaner API for PQF added, which allows you to get detailed
2668 error information for bad queries (see yaz/pquery.h).
2670 Fixed bug in ZOOM_record_get for type "database".
2672 Implemented mini iconv library supporting conversions between
2673 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2675 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2677 --- 1.8.9 2002/08/20
2679 Fixed ZOOM C record cache so that preferredRecordSyntax and
2680 elementSetName is used to check for already fetched records.
2682 --- 1.8.8 2002/08/02
2684 Added three members in bend_initrequest structure to facilitate
2685 character set negotiation.
2687 Fixed a bug in frontend server that could cause indefinite
2688 loops under rare conditions.
2690 Revised character set utilities (charneg.h) so that encoding
2691 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2693 For PQF, directive @term <type> sets term type for Scan/Search.
2694 Here <type> is general, string, numeric, null. The term type
2695 is inherited - just like @attr.
2697 New call odr_set_charset that sets character set conversion for
2698 international-strings on a ODR stream. Prototype is:
2699 int odr_set_charset(ODR o, const char *to, const char *from);
2700 The InternationalString is still represented as C string in YAZ
2701 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2702 won't). On the protocol level, you can use any encoding.
2704 Support for UNIX sockets in ZOOM.
2706 Solaris recv sometimes returns errno == ENOENT. It is treated as
2707 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2709 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2710 both client and server. Code by Morten Bogeskov.
2712 --- 1.8.7 2002/05/22
2714 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2715 that they can be used directly from Visual Basic. You must recompile
2716 your windows APP if you're using ZOOM.
2718 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2719 Commands "lang" and "charset" sets language and character set respectively.
2720 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2721 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2723 Attributes from multiple CCL fields may be OR'ed rather than merged
2724 using directive "@field or". Fields are still merged by default -
2725 equivalent to "@field merge".
2727 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2730 Fixed bug in zget for parameter ExtendedServicesResponse.
2734 --- 1.8.6 2002/03/25
2736 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2738 Client displays USR.1:SearchResult-1 (hits per term).
2740 Additional Search Info for search in Generic Frontend Server.
2742 Fixed CCL parsing of "field=s".
2744 WIN32 installer - using the excellent NSIS software from nullsoft.
2746 Fixed CCL parsing of "field = - <number>".
2748 Added function yaz_marc_decode that decodes MARC for line mode
2749 display or XML (similar to that used by JZKit).
2751 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2752 Z39.50. But ISO/ILL was, however.
2754 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2755 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2757 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2758 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2760 --- 1.8.5 2002/02/03
2762 New YAZ client features: Command completion and new commands:
2763 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2764 Code provided by Jacob Poulsen.
2766 New call oid_trav, that visits all registered OIDs via callback.
2768 Function ZOOM_record_get now returns const char pointer rather than
2769 void pointer. It saves a lot of type casts.
2771 For YAZ client, command "auth" now allows you to set authentication
2772 in IdPass style. It is enabled when three tokens are given - order
2773 is user, group and password.
2775 Fix memory leaks in MARC record handling for ZOOM.
2777 New option for YAZ client, -k <kilobytes> that sets
2778 maximum record size. Similar to -k option for generic frontend
2779 server and yaz-ztest.
2781 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2783 Prefix query parser reports "fail" when bad attribute set is given.
2785 Fix in MARC decoder. Proximity logging. Fix for attribute set
2786 in scan handler for server. Patches by Shigeru Ishida.
2788 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2791 Configure option --with-openssl=<dir> now works when a directory is
2792 specified. Patch provided by Morten Bogeskov.
2794 New option for YAZ client, -u <auth>, that sets authentication.
2796 ZOOM fix: error information was sometimes "missing", since error
2797 was cleared/reset too when it shouldn't.
2799 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2801 --- 1.8.4 2002/01/04
2803 Scan for ZOOM API. New object ZOOM_scanset. New functions
2804 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2805 ZOOM_scanset_destroy.
2807 New ZOOM function, ZOOM_connection_last_event, that returns type
2808 of last event (such as "receive data", "send data", "apdu received",
2811 New ZOOM option, schema, that specifies schema for retrieval.
2813 New CCL feature. Qualifiers can be aliases for one or more
2814 other qualifiers (if more than one is given, OR is used).
2816 ZOOM uses named result sets if target supports it.
2818 Two new YAZ client commands: . (dot, which sources a script of YAZ
2819 client commands), and ! (to execute shell command.). Implemented
2822 Working on Debian packages.
2824 --- 1.8.3 2001/11/19
2826 YAZ client enables named result sets only if target supports it.
2828 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2830 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2831 with key="host" to get same result.
2833 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2834 Function Z3950_resultset_record(s) returns references to records
2835 "owned" by resultset. To become owner use Z3950_record_clone.
2837 Function z_ext_record handles Extended Services. Thanks to
2840 --- 1.8.2 2001/11/12
2842 CCL Parser fix: ignore token comma when dealing with and-lists.
2844 Documentation updates for COMSTACK.
2846 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2847 Changed prototype Z3950_records. For some functions, int parameters
2848 were changed to size_t.
2850 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2853 New MARC decode/display function, marc_display_exl, which properly rejects
2854 non-ISO2709 records. YAZ client uses it.
2856 --- 1.8.1 2001/10/29
2858 Fix bug: local attribute set wasn't set correctly in PQF strings.
2862 * Old Z39.50 codecs no longer supported.
2864 Added ZOOM C binding. See http://zoom.z3950.org/
2866 Renamed states for COMSTACKs to avoid confusion with events.
2868 Implemented cs_look and proper cs_rcvconnect.
2870 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2872 Configure detects POSIX threads on OpenBSD.
2874 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2875 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2877 When error is returned from present handler, non-surrogate diagnostic
2878 is returned in present response (and fetch handler is no longer called).
2880 * Minor adjustments to pquery parser (PQF). Token characters may be
2881 escaped by using backslash (C-style).
2883 PQF parser allows string attribute values to be specified. For @attr,
2884 non-numeric characters after the equal-sign are treated as strings
2885 (e.g. @attr 9=title).
2887 CCL trunction character may be defined (@truncation in file)
2889 * function zget_ExtendedServicesRequest sets waitAction to
2890 waitIfPossible (was wait).
2892 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2895 CCL operator names may be set in field definition files (CCL_bibset).
2896 See ccl/bib1 for an example.
2898 Fixes in ASN.1 compiler for C++ compatibility.
2900 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2901 and "op_or" to avoid conflict with C++.
2903 Fixed problem with GNU readline detection on Redhat 7.0.
2905 Added step-size for Scan backend handler.
2907 Fixed bug that made the frontend server crash when no attribute
2908 set was specified for scan.
2910 Front-end server automatically switches to original working directory
2911 when installed as an NT service. Previously -w had to be specified to
2914 Added extended attributes for retrieval module (data1), so that data1
2915 records carry d1_readXML/SGML attributes. d1_read also supports
2916 null-data rules ( <tag/>)
2918 On UNIX when POSIX threads are available, a separate library libyazthread
2919 is created. Programmers should link with that library and the yaz library
2920 when using threads. The reason for the split was that some applications
2921 on Linux, such as Apache, doesn't work well when using shared objects that
2924 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2925 (or any frontend server) in SSL mode by specifying ssl: followed by
2926 address. Only tested on UNIX.
2928 Added feature for CCL module. Virtual structure s=al or s=ol generates
2929 and-list and or-list respectively instead of phrase search.
2933 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2934 log_mask_str. This was done to avoid name conflicts with other libraries
2935 (such as other PHP extensions).
2937 Added raw OID member for preferred record syntax (request_format_raw)
2938 and returned record syntax (output_format_raw) for backend fetch method.
2940 Config file yaz-config now accepts options so that it returns specific
2941 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2943 Shared library support for UNIX using GNU libtool.
2945 * Modified backend interface. Request/Response struct's replaced by
2946 one read/write C struct. For example bend_fetchrequest and
2947 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2948 Every handler - even search has to be registered in bend_init
2949 handler. This means that the YAZ library no longer refers to
2950 external functions and it makes it possible to make the whole
2951 thing a single DLL/SO.
2953 Added Segment handler for backend server.
2955 Added Zmbol/Zebra administrative functions to YAZ client.
2957 Threaded frontend server on UNIX (when POSIX Threads are available).
2958 Starting the server with option -T enables multi-threading.
2962 Added configure option --enable-comp/disable-comp to control use
2963 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2964 located in sub directory asn.
2966 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2967 in ${exec_prefix}/bin along with the other programs yaz-client and
2970 GNU automake used to maintain makefiles.
2972 Added several OID's.
2974 Changed retrieval module so that we can load records with no abstract
2975 syntax defined. Tagpaths in these records are fully composed of string
2978 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2982 On UNIX, the generated makefile now supports a proper 'make install'.
2983 The prefix can be set via GNU configure to set the install location
2984 (default is /usr/local).
2986 * YAZ programs client and ztest were renamed to yaz-client and
2987 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2988 locations, such as /usr/bin,/usr/local/bin,etc.
2990 * YAZ Header files were moved from include to include/yaz. YAZ Header
2991 files are referred to as include <yaz/log.h> rather than <log.h>.
2992 The YAZ include path (-I ..) is therefore the same as before. Programmers
2993 should update their #include statements or use -Ipath/include/yaz
2994 instead. The main motivation for doing this change is that YAZ header files
2995 can be installed in "standard" locations /usr/include,/usr/local/include
2996 without introducing conflicts, since ALL YAZ header files are stored
2997 in subdirectory yaz (under /usr/include for example).
2999 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3000 rather than project/workspace files. We switched because project files
3001 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3004 Changed name of logging function, logf, to yaz_log, to prevent name
3005 clash with some math-log functions. The YAZ header log.h defines logf
3006 to yaz_log (#define) so there should be no incompatibilities by this
3009 Added bend_start/bend_stop handlers for server. These handler are
3010 called on start/stop of server. For windows they are called whenever
3011 a service is started/stopped.
3013 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3014 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3015 in util/yc.tcl. The auto-generated C code structures are, in a few
3016 cases, incompatible with the old decoders. There are differences in the
3017 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3018 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3019 The preprocessor variable ASN_COMPILED is defined when the compiled
3020 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3021 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3022 wish to use the old encoders/decoders you can specify --disable-yc
3025 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3026 version so that it supports both new - and old version of DB Update
3028 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3029 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3030 change. The name parameter can be set to 0 in which no name is specified
3031 for the construction. The macros odr_implicit and odr_explicit sets name
3032 parameter to zero for the construction involved. New macros
3033 odr_implicit_tag and odr_explicit_tag are similar to the others,
3034 except that a name parameter is added. For programmers' that don't use
3035 ODR they probably only need to change the call to z_APDU and z_External.
3037 Added access control facility by interfacing the TCP wrapper library.
3038 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3039 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3040 name of the daemon and enables the access control as specified in
3041 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3043 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3044 den Dool <H.M.vdnDool@kub.nl>.
3046 Added reference ID parameter to most functions in server API - refer
3047 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3049 Changed name of ccl library to libccl.a (was ccl.a).
3051 Fixed bug in decoder for Explain (Category TargetInfo).
3053 Added support for GNU readline in client. Thanks to Jacob Poulsen
3054 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3056 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3057 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3058 IMPLEMENTATION! This change was made to the development version before
3059 the ZIG decided to retract the amendment. If any users MUST be
3060 compatible with the original Update definition, PLEASE CONTACT US, and
3061 we will include a separate definition corresponding to the old Update
3062 ES. Note that because of the change to the ASN.1 of the
3063 TaskPackageRecordStructure we cannot define a single structure that
3064 will support both versions.
3066 * Added const modifier to buffer parameter for some ODR/BER encoding
3067 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3068 completeWAIS, odr_dumpBER.
3070 Fixed bug in client.c which caused a crash when a scanResponse didn't
3071 contain positionOfTerm.
3073 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3074 * will cause an error in a client if a non-YAZ target sends both a
3075 * list of Scan entries and non-surrogate diagnostics.
3077 Retrieval module enhancements. Tag sets may be typed in the reference
3078 to it. From the .abs-file the "tagset" directive takes a third optional
3079 integer type for the tag set referenced. From a .tag-file the "include"
3080 directive takes a third optional type as well. The old "type" directive
3081 in the tag set itself is still recognized but acts as the default type
3084 Backend interface change. Individual Scan terms returned from bend_scan
3085 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3086 in include/backend.h.
3088 Retrieval module enhancements. Multiple tag sets and attribute sets may
3089 be specified in abstract syntax specs. Revised the error/warning for
3090 logging messages reported by the retrieval module when reading the
3093 Object Identifier system (oid_..) changed. The API is backwards
3094 compatible but the oid-routines now allocates new OID's when needed.
3095 Raw OID's may be specified in oid_getvalbyname.
3097 YAZ now uses GNU configure to generate Makefile(s).
3099 * Minor changes in some of the member names of DeleteResultSetRequest and
3100 DeleteResultSetResponse. See include/proto.h.
3102 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3103 and added member 'languages' in TargetInfo (which was missing).
3105 Changed the way attribute sets are handled in the retrieval
3106 module. These are now cached, just like the abstract syntaxes
3109 Changed YAZ so that it links with compiled ASN.1.
3111 Added Explain-schema definitions and mapping routines. The following
3112 Explain categories have been implemented: AttributeDetails,
3113 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3115 Fixed minor bug in Windows version of Server Library.
3117 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3119 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3121 Added EXTERNAL: UNIverse Resource Report (non-standard).
3123 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3124 ENUMERATED and SET OF.
3126 * Added 'const' to some of the char pointer arguments for the
3127 functions, data1_read_node, data1_getelementbytagname,
3128 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3131 Fixed bug in data1_insert_taggeddata - the last_child member of
3132 parent wasn't initialised.
3134 * Changed data1_read_record and data1_read_node so that the supplied
3135 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3136 doesn't refer to any parts of the "SGML"-buffer.
3138 Fixed bug in server library (Windows version of statserv_remove).
3140 * Changed code so that it compiles as C++. The type definition
3141 of Odr_fun which is a member of Odr_arm was changed. The result is,
3142 that an explicit typecast is needed for the fun pointer when
3143 using Odr_arm - as in:
3144 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3146 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3148 Implemented the new structured date and time definition as approved
3149 by the ZIG. Added schemaId element to the specificTag in Espec-1
3150 (also approved at the last ZIG). Thanks to RVDM.
3152 Added some Object identifiers (RVDM).
3154 Changed the Update Extended Service (RVDM).
3156 Added command "refid" to client which specifies referenceId for
3157 the following requests.
3159 Implemented extended service handling for server. See ztest.c
3160 for an example as well as backend.h. New handlers are registerd
3161 in the Init handler.
3163 * Changed interface for sort in server.
3165 Added new members to statserv_options_block. It allows a server
3166 to read options from another source than just the command line. Thanks
3167 to Charles Woodfield.
3169 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3170 renamed to zboolean. Some C++ compilers complained about the name.
3172 Minor changes to gils.abs. Added index 's' (sort) on title
3173 and date/time-last-modified.
3175 --- 1.4pl2 1998/1/30
3177 Fixed bug in server library regarding inetd mode (-i). This bug
3178 was introduced by release 1.4.
3180 --- 1.4pl1 1998/1/29
3182 Added sort facility in client and backend server interface.
3184 Fixed problem with dependencies in Makefile(s).
3186 Fixed bugs for encoders/decoders of extended services and
3189 Implemented sub-tree feature for schemas. Sub-trees are
3190 referenced in *.abs-files. See explain.abs for an example
3191 of the use of this feature.
3193 Modified bib1.att; local attributes for ANY didn't include
3194 ANY itself (only affects use of the retrieval module).
3196 Fixed bug in plain SGML reader in function data1_read_node:
3197 tags with prefix "var" was incorrectly interpreted as variants.
3199 Added feature "sub-schemas" to enable references to - and definitions
3200 of - group of elements.
3202 * Removed member parent from type data1_element (in data1.h).
3204 Implemented function odr_nullval() that returns the value of
3207 * Removed member num_children from data1_node (in data1.h).
3209 Made NT service interface part of the server library. The
3210 function statserv_main uses the NT service when required and
3211 calls the statserv_start / statserv_close routines.
3213 Routine zget_SearchRequest and zget_PresentRequest fills
3214 resultSetName/Id member with "default" instead of "Default".
3216 Fixed memory leak in server. Request queue member wasn't freed.
3218 Fixed nmem_exit so that memory is freed.
3222 Revised the CCL parser utility to be thread safe.
3224 Added function, oid_ent_to_oid, to replace the function
3225 oid_getoidbyent, which is not thread safe.
3227 * Added nmem_init and nmem_exit to initialize and release
3228 NMEM resources. Function nmem_init should be called once in the
3229 initial thread before NMEM/ODR is used. statserv.c and client.c
3230 have been changed accordingly. The change was necessary to make
3231 NMEM thread safe. The NMEM memory pool is shared amongst threads
3232 in a process. Unix-based applications will still work fine without
3235 Added NT Services interface for the the Z39.50 (statserv) Server.
3236 Refer to the ztest.c source on the usage.
3238 Windows 95/NT port using MSVC5.0. Project files are included in the
3241 * Defined new 'global' handle for the retrieval (data1) system. The
3242 new handled, data1_handle, describes the state of the data1 system.
3243 This handle is passed as first argument to virtually all
3244 data1 related routines. The functions data1_create and data1_destroy
3245 creates and destroys a data1 handle respectively.
3247 Added ODR encode stream member to all backend request structures
3248 init, search, scan etc. This stream should be used to allocate all
3249 memory used for the response when thread safe operation is needed.
3251 Changed the comstack utility, cs_addstr, to be thread safe. The
3252 returned hostname string returned by the function is now part the
3255 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3256 function. The cs_straddr takes a COMSTACK handle as argument, so this
3257 function must be used after cs_create and before bind/connect.
3258 This function is thread safe.
3260 Moved test server to 'ztest' directory - generic server code still
3261 in 'server' directory.
3263 Made prefix query (pquery.c) utility thread safe.
3265 Added new function modifier YAZ_EXPORT to 'export' public DLL
3266 functions when using windows (see include/yconfig.h).
3268 Added definitions to the OID database (util/oid.c) (RVDM).
3270 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3272 Added call to ccl_rpn_delete in client program.
3274 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3275 release of RPN structure.
3277 Added support for C++, headers uses extern "C" for public definitions.
3278 With input from RVDM.
3280 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3281 Thanks to Ronald van der Meer (RVDM).
3283 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3285 Added support for private extensions to the OID database
3286 (oid_setprivateoids()). Thanks to RVDM.
3288 Added optional, physical ANY (key replication)
3290 Fixed null-reference problem in GRS-1 output filter.
3292 Proximity operator added to Prefix Query Format (PQF).
3294 In test client command "base" accepts multiple databases.
3296 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3300 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3302 Smallish bug-fixes in the new encoders/decoders (explain).
3304 Bug fixed in DeleteRequest.
3306 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3308 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3310 Added SOIF syntax (using private OID for now) to retrieval module and client.
3312 Added Update extended service.
3314 Added SearchResult-1 additional info structure.
3316 Added optional CCL (ISO8777) interpreter as separate module. Available
3319 --- 1.2 1996/6/10 (1st anniversary release)
3321 Added Summary record syntax. Lightly tested.
3323 Added OPAC record syntax. Untested.
3325 Added ResourceReport service encoders/decoders. Untested.
3327 Fixed bug in z_Unit - wrong tagging on unitSystem.
3329 Fixed bug in the DiagRecs decoder.
3331 Added options for max PDU size and session timeout to frontend-server.
3333 Added documentation of query-language parsers and other supporting utilities.
3335 [frontend-server] Added Attribute set to the bend_scanrequest API.
3337 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3338 surrogate diagnostics were generated.
3340 [retrieval] Allow multiple local values for attribute.
3342 [retrieval] Allow multiple attributes per element in .abs files. index type.
3344 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3346 --- 1.1pl2 1996/4/10
3348 Minor changes, mostly specific to Zebra's requirements (retrieval)
3352 Repaired bug in frontend server when running multiple listening
3353 endpoints in dynamic mode.
3355 z_External() now won't break if a known, ASN.1 value comes encapsulated
3356 in an octet-string. The value will pass through unmodified in an Odr_oct.
3358 Added a bit of code to the demo client to decode & display
3359 ASN.1-structured records represented in the octet-aligned branch of
3360 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3362 Added z_ext_getentbyref() to the ASN module. Doc updated.
3364 * Completed the SCAN definition in the ASN module. This may break SCAN
3365 code based on older YAZ-versions at compile-time. The fix is easy -
3368 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3369 under the SCAN definition. Remember to initialize this, server-people.
3371 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3372 that this does not extend to ODR and ASN.
3374 Comstack allows insertion of established socket (primarily for
3375 inetd-operation of servers). Doc updated.
3377 Front-end server can now start from the inetd in TCP mode. Doc
3380 --- 1.0pl4 1996/1/24
3384 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3385 the rank and record number.
3387 Adjustments to the frontend server.
3389 Fixed diagnostic BER dumper. It ignored the file argument.
3393 Various changes to retrieval module.
3395 Changed the union discriminators of the protocol files from enums to
3396 ints paired with #defines.
3398 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3401 *Changed operator in the RPN structure to 'roperator', again to avoid a
3404 Fixed problems in Explain decoders/encoders.
3406 --- 1.0pl2 1995/12/6
3408 Memory bug in log module fixed.
3410 --- 1.0pl1 1995/12/5
3412 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3414 Bug in Explain DatabaseInfo module fixed.
3416 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3420 The shift to v1.0 signals that we now consider the *core* functionality
3421 of YAZ reasonably stable (the core being more or less equivalent to
3422 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3423 tested (Explain not at all - though that will happen soonish).
3425 Minor changes to code to support Windows port.
3427 Various minor changes after we're getting to use GRS-1 & co. more.
3429 Added Espec-1 format.
3431 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3432 of the protocol and it cannot be selected when encoding (maps into 'string'
3433 when decoding). Needed to talk to some servers.
3435 Demo client can request simple element set names.
3437 Added Diagnostic Format encoders/decoders.
3439 Added simple Close handling to frontend server (no hooks for resource
3440 reporting yet), and demonstration client.
3442 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3444 --- 1.0b3 1995/08/24
3446 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3447 handled incorrectly when records were requested in the searchResponse. This
3448 will only affect you if you use the frontend-server.
3450 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3451 Test-client will ask for and print GRS1. Ztest will return dummy records
3454 Added Explain encoders/decoders to the service-level API. Untested.
3456 Added Extended Services: Item Order encoders and decoders to the Service-
3457 level API. Untested. We could use a recent copy of the pertinent bits
3458 of the ILL protocol to add those bits.
3460 Added diagnostic format 1 encoders/decoders to the service-level API.
3463 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3464 odr_cons.c, which causes a more correct output.
3466 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3467 was always set to 0 when no records were requested in the searchRequest.
3469 * Added better external-handling. This shouldn't harm old code that
3470 *encodes* externals. It can break code that looks for a
3471 'single-ASN1-type' representation, since those types that are known
3472 are now decoded immediately. Look at the SUTRS sample code in
3473 seshigh.c and client.c. Documentation updated.
3475 Handling of structured records in bend_fetchresponse. Length -1 marks
3476 structured record, type is deduced from format field.
3478 --- 1.0b2 1995/06/27
3479 Fairly quick maintenance release to add SUTRS support.
3481 Fixed handling of SUTRS records in the demonstration client.
3483 * Added format field to the bend_fetchrequest and bend_fetchresponce
3484 structures of the backend API (frontend server). When the record is
3485 returned, the value of the format field is mapped to an OID. The
3486 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3487 of the record. The special value VAL_NONE in the bend_request means
3488 that no specific format was requested by the client. Documentation
3489 updated accordingly. Test server (ztest) will return a fixed dummy
3490 SUTRS record if your client requests SUTRS.
3492 Documentation updated accordingly.
3494 You can now set external libraries and RANLIB support in the top-level
3498 First public release.
