3 ZOOM: special options to control APDU logging.
4 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
5 logging of APDUs until "saveAPDU" option is set again. If logging is
6 already enabled the effect is that current APDU buffer is cleared.
7 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
8 logging (default behavior on new connection).
9 The APDUs sent/received can be obtained by using
10 Using ZOOM_connection_option_get(c, "APDU") or
11 ZOOM_connection_option_getl(c, "APDU", &l).
13 GFS: relay implementation_version from backend
14 From 3.0.40 and later, implementation_version from backend was
15 not used in init response at all.
19 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
20 mode at all. Probably never did.
22 Make a new version of ztest.pem that, at least, is not expired.
26 Fix description of CCL directive 'case'.
28 More tight checking of form arguments (yaz_uri_to_array). Makes
29 YAZ better at rejecting big and/or bad POSTs.
31 SRU decoding does not report more than up to 10 invalid arguments.
33 rpn2cql: less quotes in generated terms. Semantics unchanged, but
34 it's prettier this way.
38 New utility yaz_decode_init_diag. Defined in proto.h.
40 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
41 given for unix local socket.
42 The COMSTACK string for doing so is:
45 unix:/myfile:tcp:localhost:9999/mybase
46 unix:/myfile:localhost:9999/mybase
47 unix:/myfile:http://fakehost/mybase
49 debian: Use dpkg-buildflags in build process.
53 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
54 global's SRU service uses a recordPosition scheme starting from zero.
55 First record's position should be one
56 according to the standard.
60 Allow more namespaces for SRU. This is to allow, for example, an
61 incorrect namespace returned from server
62 http://services.igi-global.com/sru .
64 Minor fixes for compilation on Windows.
68 daemon: log total number of bad signals from child on stop so that it
69 is more easy to spot problems with child worker processes.
71 retrieval: empty backend name attribute omits element set
72 from being used in retrieval.
76 Implement Solr sort strategy "solr", similar to sru11 sorting.
77 This will implement the correct parameters on Solr requst to do
82 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
85 MARC: Extra/missing indicator handled for MARCXML.
86 The indicator length is given in header and is the same for the
87 whole record. If attributes ind1, ind2 are missing, then content
88 character defaults to blank. Extra indicator attributes (beyond)
89 indicator length are treated as an error.
91 Reformat: delete trailing whitespace
95 MARC: fix non-ASCII characters for leader. This is to ensure we can
96 generate XML in UTF-8.
98 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
99 in one node with structure word.
101 --- 4.2.37 2012/09/04
103 yaz-json-parse: JSON output may be pretty printed by using option
106 Increase default value of max message for Z39.50 Init for GFS, ZOOM
107 and yaz-client. Old value was 1 MB. New value is 64 MB.
109 --- 4.2.36 2012/08/22
111 yaz-client: don't display bogus records from SRU servers. Some SRU servers
112 return more records than given by *maximumRecords*. Skipping those in
115 record_render: simplify buffer return handling and fix at least one bad
116 memory reference, that broke the test_embed_record sometimes.
118 Allow http://user:pass@host notation for yaz_url_exec.
120 zoomsh: allow shell command to be executed. Via the system(3) call.
122 yaz_poll: Allow num_fds == 0
124 yaz-client: fix bad encoding of "itemorder item". The itemorder
125 item <no> - command forgot to use length of encoded Item Request
126 package. Error present since YAZ 3.
128 yaz-ztest: fix bad usage of session handle. Bug was introduced when
129 result sets were saved (271a9c83).
131 SRU recordPacking: guess record packing in response rather than looking
132 at the recordPacking element which, OF COURSE, changed semantics in SRU
135 Decode SRU 2.0 responses. The official namespace for responses, according
136 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
137 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
138 nature.com's server, however, usee namespace
139 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
140 we are now using a glob-expr to match up the namespace. ZOOM C and
141 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
142 I can not find a single real example showing the "real" namespace in
143 the documentation from OASIS. The namespace for requests is different
144 from responses, but this is not added to YAZ yet, when we don't encode
147 --- 4.2.35 2012/06/26
149 zoom/record_render: add support for Base64 decoding fo MARC records
150 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
151 which will decode base64 + ISO2709 marc-8 encoded material from text node
154 --- 4.2.34 2012/06/07
156 Add missing definitions ZOOM_resultset_get_facet_field_by_index
157 and ZOOM_resultset_facets_names.
159 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
162 Change APDU dump printing to avoid long leading blanks. For levels 16
163 or larger the level is shown and the indentation is truncated but
164 recursed with modula 8. This makes it still reasonable easy to read
165 - even for nested BER dumps.
167 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
168 return 0 (incomplete package) in case where the BER package was
169 considered too nested (return value of -2).
171 dumpber: lines of level 15 are not indented further. Two spaces per
172 indentation; indentation 15 or more is indented to a fixed indentation
173 and augmented with a level=<no> indication.
175 zoomsh: increase max size of command+args
177 GFS: No limit in RPN buf size in CQL to RPN conversion.
179 --- 4.2.33 2012/05/09
181 New function for daemon utility, yaz_daemon_stop .
183 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
185 --- 4.2.32 2012/04/25
187 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
188 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
190 --- 4.2.31 2012/04/23
192 YAZ daemon utility relays SIGUSR1 to child process.
194 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
195 would result in en empty database list - which in turn would result in
196 encoding failure for search.
198 Fix reading beyond string in yaz_sort_spec.
200 --- 4.2.30 2012/04/11
202 Add two new SRU diagnostics:
203 236: Access to specified database denied
204 1015: Init/AC: Maximum number of simultaneous sessions for Userid
206 Document the very useful ZOOM-C option "apdulog".
208 CQL to RPN: term may be passed through verbatim. This is enabled with
209 truncation.cql . The assumption being that the term is already CQL.
211 --- 4.2.29 2012/03/20
213 record_conv: leader spec may be given for marc element.
214 The leader spec is given as attribute leaderspec for element marc.
215 For example to convert a MARC21 record from MARC-8 to UTF-8:
216 <marc inputformat="marc" outputformat="marc"
217 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
219 record_conv: allow user-XSLT params. For example:
220 <xslt stylesheet="MARC21slim2DC.xsl">
221 <param name="myparameter" value="myvalue"/>
222 <param name="otherparameter" value="othervalue"/>
225 record_conv: fix error handling for missing marc charsets.
227 CQL: fix extra terms in wrong order.
229 --- 4.2.28 2012/03/06
231 record_conv: modify new API for conversion types. The conversion types
232 may be passed in new functions yaz_record_conv_configure_t and
233 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
235 Avoid mixed statement/variable declare; fixes compilation with Visual
238 --- 4.2.27 2012/02/28
240 Add non-standard SRU diagnostic: 235: "Database does not exist".
241 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
242 Update SRU to Bib-1 diagnostic maps accordingly.
244 CCL: add two new diagnostics for unsupported masking. The new
245 diagnostics are: "Embedded truncation not supported" and
246 "Single charcacter mask not supported".
248 --- 4.2.26 2012/02/23
250 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
252 --- 4.2.25 2012/01/11
254 Build YAZ for Ubuntu Oneiric.
256 CCL: allow parantheses for proximity operands. For example CCL query
257 (a) % (b) is now allowed.
259 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
260 marked dead, rather then being destroyed. If not, the session memory is
261 being free'd before the search/scan handler is finished. Also destroy
262 'request' memory in request_release rather than in various places,
263 which resulted in leaks from time to time.
265 --- 4.2.24 2011/12/21
267 cql_sortby_to_sortkeys: honor sort prefix.
269 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
270 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
271 The rpn2cql family of functions now always returns quoted CQL terms.
273 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
275 --- 4.2.23 2011/12/15
277 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
278 sequence is treated as one. For example, &&a=b&&&c& is identical to
281 --- 4.2.22 2011/12/05
283 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
284 APDUs for a connection to a WRBUF.
286 --- 4.2.21 2011/11/23
288 Fix cql_sortby_to_sortkeys. Completely broken before.
290 Make CCL's @truncation work again.
292 --- 4.2.20 2011/11/09
294 New ZOOM connection setting: tproxy. It's like proxy, but does not
295 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
296 to set resolved address + port for a connection outside ZOOM itself.
298 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
300 --- 4.2.19 2011/11/07
302 Fix uninitialized variable in Solr spell support (could cause SEGV
303 for SRU response decoding).
305 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
306 back-end's addinfo through into the ZOOM response addinfo.
308 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
309 they are separated by a colon and a space rather than simply
312 --- 4.2.18 2011/10/28
314 Add support for Solr spell-checking/suggestions through ZOOM.
315 If a Solr target has been configured correctly for spelling-checking
316 and suggestions, these will now be returned on the ResultSet option
317 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
319 --- 4.2.17 2011/09/28
321 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
322 with a flag whether to substitute escape sequences or not.
324 --- 4.2.16 2011/09/22
326 Fix nmem_strsplit_escape to substitute escape char properly.
328 New option for zoomsh -e , which makes it abort on first error and
329 return process exit code to indicate success/failure.
331 YAZ options utility supports special option -- which makes all it treat
332 all following arguments as non-options.
334 --- 4.2.15 2011/09/16
336 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
337 searched if absolute filename is given.
339 Fix conv_xslt() error-reporting when stylesheet is not found.
340 (The value of fullpath is meaningless in this situation.)
342 --- 4.2.14 2011/09/07
344 Fix problem in CQL sort node creation: un-initialized memory.
346 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
347 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
348 CQL sortby depending on whether Type-1 or CQL is actually sent to the
351 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
352 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
354 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
355 will make it possible to use both single-character mask (#) and wildcard (?)
356 in CCL . Throw diagnostic for left truncation because that is not supported
359 --- 4.2.13 2011/09/01
361 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
362 cases using escapes (\-sequences) and masking.
364 PQF parse fix: A trailing backslash followed by end-of-string (\0)
365 would result in a read one byte beyond string.
367 rpn2ccl may use Z39.50 masking for terms (t=z).
369 ICU check fix. Don't include library -lCrun on Solaris, unless present.
371 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
372 not --cppflags (which seeems like an error in icu-config).
374 --- 4.2.12 2011/08/27 RPM package only
376 cql2ccl: fix conversion of terms: operator characters were not
379 --- 4.2.11 2011/08/25 RPM package only
381 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
382 CCL parser will map both # and ? to their regular expression
383 quivalents (. and .*).
385 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
386 of reserved CQL characters.
388 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
389 is, so that they are passed through.
391 --- 4.2.10 2011/08/24
393 ZOOM SRU mode: more aggressive re-connect.
395 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
396 made available as a utility function, declared in <yaz/logrpn.h>
398 rpn2cql_structure() supports proximity nodes (except that the Type-1
399 proximity node's "exclusion" binary is ignored, as there is no way to
400 express that in CQL). Fixes bug #4564.
404 Fix SEGV that could occur if set command of zoomsh was given without
405 value (2nd argument).
407 Fix SEGV that could occur if unsupported transport was given for
408 COMSTACK - say https (when SSL was unavailable).
410 Build yaz-url on Windows too.
414 New utility to get web content. Header is url.h. A command line tool
415 yaz-url is part of the distribution and packages.
417 Fixes for SSL COMSTACK (when gnutls is in use).
419 New functions yaz_base64{encode,decode}. Header is base64.h.
423 ZOOM C includes HTTP response buffer as additional info if it fails
424 to decode the SRU response.
426 Make wrbuf_json_puts available.
430 zoom: throw diagnostic for invalid value for option "sru". Before a
431 bad SRU request was sent.
433 Adding new utility wrbuf_vp_puts.
435 Add cclxmlconfig.obj to win/makefile. It was missing completely.
439 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
440 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
441 redirect was used at the same time.
443 MARC line mode decoding: be less picky about length given - first
444 5 digits of header that is.
446 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
448 Changes to decoding of SRU records: a record with recordPacking=xml is
449 modified with a new root element <yaz_record> if the recordData contains
450 multiple children elements. This is to make the record XML parseable
453 RPN to SOLR conversion: encode special characters.
455 Generic Frontend Server: fix uinitialized member, stepSize.
459 Fix a bug in SRU decoding of records.. The database records stored
460 had un-initialized memory, but it would only be seen with yaz_record_render
461 and type_spec="ext" .
463 Fix a bug in ccl_qual_dup introduced in 4.2.3.
467 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
471 Add new utilities to convert from CQL to CCL . These utilities have
472 prefix cql_to_ccl defined in cql.h.
474 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
475 lead to memory heap corruptions when ICU utilities were in use.
479 Make compilation work without Libxml2.
481 yaz-client: remove redundant blanks in display of searchResult-1 term
486 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
487 resulting CQL node (tree) in a new node CQL_NODE_SORT.
489 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
490 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
491 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
492 Note that the CQL sortby spec is only converted when the GFS is already
493 converting from CQL to RPN (cql2rpn element).
495 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
496 specify whether to collapse delimitors or not. The existing nmem_strsplit
497 do collapse (collapse parameter = 1).
499 Windows installer: For NSIS, set InstallDir depending on x86/x64.
501 Rename internal func yaz_use_attribute_create. While non-static, this
502 function is not declared in a public header.
506 Add -lCrun when linking with ICU on Solaris.
508 More quicks character set conversions for OPAC records.
512 fix problem with record_render: records were converted (character set
513 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
517 SRU: add methods for handling DADS SRU-proxy facets.
519 Separate OPAC record character set for ZOOM_record. yaz_record_render
520 allows a character set given as charset=from/opacfrom,to where 'from' is
521 the character set of a bibliographic record, 'opacfrom' is character set
522 of OPAC record and 'to' is the target character set.
526 yaz-client: show may XML format records. Command show followed by 'format'
527 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
530 src/stemmer.c: Avoid using unnamed union. It is not supported by some
533 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
536 Update yaz.spec to operate on both SLES11 / Centos 5.5.
538 RPM: Release includes 'indexdata' name. Use indexdata in release name so
539 this package can be distinguished from other vendors.
541 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
542 as determined by configure
544 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
546 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
547 returns no error and no record, the present request is considered
548 partial (only a subset of the records could be returned by backend), and
549 so it is appropriate to set Present Status to partial-4.
553 Move yaz-config man pages to section 1.
555 More documentation about SOLR.
557 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
558 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
559 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
560 peers on some Linux systems. However, in general that does not work
561 so YAZ can not rely on that to work. Debian changed behavior in this
562 respect from Debian lenny to Debian squeeze (still testing as of Oct
564 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
566 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
570 Fix yaz-config output: echo_source not set correctly by configure.
574 SOLR WebService support for yaz-client and ZOOM.
576 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
578 --- 4.0.12 2010/08/17
580 Z39.50 facet support. Facet specifications are passed for search in
581 other-information with ASN.1 as defined in facet.asn and OID
582 .10.1000.81.5 . Facets are expressed as an Attribute list as known
583 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
584 3 is limit (number of entries to get in response). yaz-ztest returns
585 dummy facets if a client asks for them.
587 --- 4.0.11 2010/07/09
589 CCL fixes: bug 2895 and bug 3539.
591 GR1-display: add comma in display - was removed by mistake in
594 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
596 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
598 --- 4.0.10 2010/06/18
600 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
601 result set from a connection. The result set will be on its own
602 thereafter; no operations on it will perform retrievals from a target.
603 Only cached copies are returned.
605 ZOOM C:fix case for HTTP servers responding with Connection:close.
606 Ensure that if there is a current task it is resumed (like fetching
607 more records in a result set) . Bug #3484.
609 PQF parser: use odr_atoi for Odr_int (not atoi)
611 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
612 values that contain any non-digits are treated as string attributes
613 (previously decoding only checked for leading character ([0-9]). PQF
614 encoding: attribute string values are not surrounded by double-quotes.
618 New utility for managing threads - thread_create.h.
620 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
621 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
622 but YAZ' implementation do.
624 Fixes for yaz_cond-functions on Windows 7.
626 DLL export more symbols.
628 zoomsh: show record do NOT render opac.
630 Remove *.la files from Debian and RPM packages.
634 Debian package libyaz-dev depends on libgnutls-dev again (was
635 removed in YAZ 4.0.6, but due to Libtool it is still needed
636 even though yaz-config do not list libgnutls libs).
638 ZOOM: Use only one WRBUF for returning string results for
639 ZOOM_resultset. Reduces memory usage for ZOOM in general.
641 ZOOM: ZOOM_connection do not use a shared pointer to
642 ZOOM_resultset after ZOOM_resultset is destructed by
643 user. Reverts to YAZ 4.0.4 behavior.
647 record-conv: fix problem with at least one XSL conversion -
648 due to probably incorrect usage of XML XSL documents.
652 Fix yaz-config for static mode and the use of SSL (gnutls).
656 Forward decl timeval struct in mutex.h and gettimeofday.h.
658 yaz-config: fix 'static' mode linking.
662 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
663 are wrappers for pthreads or Windows. For Windows these are put in
664 a separate DLL: yaz_cond4.
666 libyaz.la (whole source) is compiled with thread. If thread support
667 is enabled enabled, all source of YAZ is compiled with treading support.
668 This allows core utilities such as yaz_log to use thread facilities.
669 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
670 thread utilities. This commit moves mutex utilities (mutex.c) from
671 libyaz_server.la to libyaz.la.
673 yaz-json-parse displays leading text until error.
677 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
678 patch from Giannis Kosmas.
680 SRU: no longer URL encode SRU database. The URL for an SRU server is
681 a URL and such is alreeady encoded - at least when given with leading
682 http:// or https://. This reverts behavior to YAZ 3.0.50.
684 Support for new MARC XML notation TurboMARC which like MARCXML is a
685 complete representation of MARC/ISO2709.. This one, however, is more
686 compact and allows for faster processing with XSLT. TurboMARC can be
687 used in the marcdisp.h API, from the yaz-marcdump utility and from
690 yaz-ztest can be configured - via the database - to perform certain
691 delays when it performs operations search, present and single record
692 fetch. This allows testers to make yaz-ztest act as a real or even slow
693 Z39.50 server. Refer to the yaz-ztest man pages for details.
697 wrbuf_destroy allows NULL WRBUF passed to it.
699 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
701 Add ZOOM_connection_close.
703 No fixed size buffers for ZOOM shell - bug #3257.
705 tstodr: make it work on s390 platform.
707 New icu iterator-functions. The new icu_iter-functions makes it possible
708 to use ICU chains from many threads.
710 yaz-client: better syntax check for show command.
714 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
717 New simple local-file XML include facility which allows file glob-patterns.
718 Refer to yaz/xml_include.h.
720 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
723 ZOOM_record_get supports new parameter "format" which makes it format XML
726 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
727 JSONText in ECMA-262) is JSONValue, not JSONObject.
731 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
732 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
734 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
735 POSIX/Unix builds .so with major version 4.
737 Remove old LOG_-defines from log.h. They have been obsolete and
738 undefined by default for the last 5 years.
740 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
742 GFS: Remove socket (int *fd) from search_rr handler. The socket
743 descriptor ptr is a facility that allowed a search handler to supply
744 a socket which would serve as a callback - when search was complete.
745 This facility has now been in use for years.
747 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
748 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
749 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
750 returns 'const char *' rather than 'char *. The returned string is
751 read-only and should not be modified by applications. COMSTACK cs_close is
752 now a void function - it no longer returns int. No applications check for
753 the value and the implementations has always returned 0.
755 ZOOM: use size_t for scan hit counts and str size. Functions
756 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
757 occ (hit count) and len (string length) are now of type size_t pointer
758 rather than int pointer. This is to be able to represent large hit counts
759 and to also just to use the proper type for string length (strlen result).
761 New JSON parser. Refer to include/yaz/json.h .
763 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
764 Used to be int in some cases. Many wrbuf_-functions used to return an int
765 indicating some length.. These return values were never used. And so they
768 ODR: odr_malloc, odr_total now takes size_t for size.
770 clone_z_type: fix leak; occurred for encoding failures.
772 --- 3.0.52 2009/12/03
774 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
775 bug was introduced in 3.0.51.
777 --- 3.0.51 2009/12/02
779 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
781 tcpip comstack: fix leak for getaddrinfo.
783 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
784 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
785 Decoding of SRU "path" database is performed by private function
786 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
787 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
789 yaz-client: honor base command for SRU. Change when database setting
790 is applied for SRU and ensure it is kept when a connection is reset.
791 Change also the way errors are displayed or SRU (decoding of packages).
793 --- 3.0.50 2009/11/02
795 Add support for extra request / response data for SRU codecs and GFS.
796 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
797 for extra data response buffer and length. For the GFS, both request
798 and response data (XML) is carried in extra_args and extra_response_data
799 for the search handler. Patch by Ko van der Sloot.
801 ZOOM: For queries that cannot be converted to the specified rpnCharset,
802 ZOOM now returns a diagnostic on the client-side ('invalid query' /
803 10010). This fixes bug #2113.
805 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
806 cmdfile included a 'quit' command that would result in a memory violation.
808 --- 3.0.49 2009/10/01
810 Make a number of functions defined in xmlquery.c static. These have
811 never been declared in a public header file (yaz/xmlquery.h) and was
812 made public by mistake.
814 Improve speed of character conversions (iconv utilities). This makes
815 conversions from MARC-8 faster.
817 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
818 unless type desired is "raw". This will prevent type "xml" from
819 returning ISO2709 .. Which obviously can not be XML parsed.
821 Fix memory leak in ZOOM that would occur if option apdulog was used
822 on a re-used connection.
824 Frontend server logs HTTP requests.
826 Frontend server now sends Z39.50 close when it times out (sesssion has
827 been idle for too long). Versions 2.0.30 and earlier also sent close.
828 But due to a mistake this was disabled in all versions after that, i.e.
829 the server would just close the socket immediately.
831 yaz-client emits a better message when receiving an unrecognised
832 userInformationField.
834 Skip zero-length subfields when decoding ISO2709. This rare case happens
835 if a record has two FS characters in a sequence. Without this patch
836 there would be a reference beyond char array in using_code_len fragments
839 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
841 --- 3.0.48 2009/08/28
843 The show command offered by the zoomsh command now takes a 3d optional
844 parameter type which is what is passed to ZOOM_record. If the type
845 argument is omitted, "render" is used.
847 RPN to CQL conv may use USE string attributes (bug #2978).
849 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
851 --- 3.0.47 2009/07/08
853 Function yaz_xml2query allows a diagnostic element in the PQF XML
854 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
855 code and additional info respectively.
857 The BER BOOLEAN is now the integral type Odr_bool which still happens
858 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
859 typedef'd to Odr_int. This is still an integral 'int', but it may be
860 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
861 ASN-1 compiler as well as programs has been updated to use the new types.
863 --- 3.0.46 2009/06/08
865 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
866 only the bibliographic record was rendered. For type=opac, an OPAC
867 record is only returned if it is present.
869 iconv: small fix for encoding of advancegreek.
871 yaz-client: avoid double display of SRU/SRW records (bug #2798).
873 yaz-client: option auto_reconnect=on really reconnects.
875 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
877 server: avoid null ptr ref for for yaz_poll errors.
879 build: fix RPM build for RHEL 5.3.
881 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
883 --- 3.0.45 2009/03/31
885 Fixed bug #2709: TCP connect returns Invalid argument.
887 Fixed compilation for mingw.
889 Honor charset for raw records (ZOOM_record_get).
891 Fixed use of errno for threaded mode that was seen on Solaris 10.
893 Fixed argument passing with blanks in value for Windows Service.
895 Disable YAZ' own log rotate by default (no 1 GB limit).
896 The variable l_max_size which specifies the log file limit is set to 0
897 (DISABLED): This is due to the fact that YAZ is most often deployed using
898 logrotate. Also YAZ can not perform log rotate because of unsufficient
899 permissions (setuid).
901 --- 3.0.44 2009/02/17
903 List supported encodings in man page for yaz-iconv.
905 Fixed missing SSL libs for --libs output
907 Re-established OID record syntax application-xml. Nobody should use it
908 but we don't want to change soname because of this symbol being absent.
910 --- 3.0.42 2009/02/02
912 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
914 Added member named_result_sets for init handler struct for the GFS. This
915 allows a server to disable named result sets.
917 Removed OID record syntax application-xml.
919 Added support for rule-based transliterator for ICU wrapper of YAZ.
921 Fixed bug #1902: yaz-icu XML output.
923 Make YAZ checks Emacs friendly.
925 BITSTRING value shows value. Bug #2346.
927 ISO2709 decoding: skip control characters from indicator data.
929 Omit sort key by default in yaz-icu's output.
931 Allow combined single char options (again) for YAZ' options function.
933 Utility yaz-marcdump got option to display YAZ version (-V).
935 Allow YAZ to use ICU 3.4.
937 Added new ICU test case which illustrates removal of diacritics.
939 --- 3.0.41 2008/12/29
941 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
943 --- 3.0.40 2008/12/29
945 For configure, using option --without-xml2 also disables Libxslt/Libexslt
948 Fixed bug #2352: yaz-marcdump crashes for certain record.
950 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
952 Added support for Danmarc2 to UTF-8 conversion.
954 Added support for ISO5426 to UTF-8 conversion.
956 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
957 implementation version.
959 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
961 --- 3.0.38 2008/11/10
963 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
964 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
966 ZOOM C now interprets databaseName option for ZOOM connection as path
969 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
971 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
973 Dummy Libxml2 types no longer defined in headers of YAZ'.
975 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
978 --- 3.0.36 2008/09/26
980 Various ODR chapter fixes.
982 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
984 Added missing source for Windows compilation, mutex.c.
986 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
988 For SRU connections in ZOOM all records up to "count" are now fetched.
990 Fixed crash in generic frontend server (and yaz-ztest) which occurred
991 in Windows due to bad error handling for Libxml2.
993 Added facility for sending arbitrary records (ASN.1 any) using
994 ZOOM C's Extended service update. Patch by Sam Reynolds.
996 New options for ZOOM C's connection, logapdu which makes ZOOM log
999 --- 3.0.34 2008/06/18
1001 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1003 --- 3.0.32 2008/06/12
1005 Fixed memory violation that could occur when decoding UTF-8. This bug
1006 was only present in 3.0.30 of YAZ.
1008 --- 3.0.30 2008/06/06
1010 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1011 GNU TLS is used by default (if found).
1013 yaz-ztest returns OPAC records if a client asks for OPAC.
1015 Improved speed of MARC-8 encoding.
1017 Added support for lossy and loss-less MARC-8 encoding.
1019 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1021 Added new Windows Service wrapper (sc).
1023 yaz-client's itemorder command may now send a file.
1025 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1027 Added new function yaz_log_xml_errors.
1029 Allow (but warn) unknown XML attributes in MARCXML parsing.
1031 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1033 The UTF-8 to MARC-8 conversion now uses a different set of characters
1034 for Greek symbols. Bug #2120.
1036 --- 3.0.26 2008/02/21
1038 Added yaz_daemon (daemon.h).
1040 Fixed bug #2068: pkg-config trouble
1042 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1044 --- 3.0.24 2008/01/28
1046 Document --with-xml2 option.
1048 Added OPAC XML XSD (etc/opacxml.xsd).
1050 Allow glob mask for name attribute in retrieval element for the
1051 generic frontend server's retrieval facility.
1053 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1054 except POLLIN/POLLOUT.
1056 Fixed error handling in cs_listen. Bug #2037.
1058 --- 3.0.22 2008/01/20
1060 Fixed version in yaz/yaz-version.h.
1062 Fixed bug #2027: Crash when closing connection.
1064 Changed configure so that ICU support is only enabled if only ICU
1065 and Libxml2 is available (because the ICU chain is XML based).
1067 --- 3.0.20 2008/01/15
1069 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1070 is built. Only this DLL depends on the ICU runtime.
1072 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1073 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1075 Changed license of CCL module to 'Revised BSD'. After consultation with
1076 remaining members of the original EUROPAGATE consortium, we are re-issuing
1077 the CCL module without a separate license. The software was developed by
1078 Index Data as part of a research project. The special license was included
1079 to help feed usage information back to the project consortium to support
1080 project evaluation. At this time, the project consortium has long-since
1081 disbanded, and the majority of the original principals have retired. At the
1082 same time, we have significantly modified the software during the following
1083 years, to the point where very practically no original code remains. To
1084 simplify re-use of the software, we have contacted those members of the
1085 consortium who could be reached, and agreed to re-issue the module as a
1086 proper part of the YAZ package.
1088 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1090 CQL closer to being version 1.2 compliant. CQL also allows free-form
1091 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1094 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1095 bug could make Extended services handling crash in the ZOOM layer. This
1096 bug was only present in YAZ 3.0.18.
1098 --- 3.0.18 2007/12/19
1100 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1103 yaz-marcdump reads and writes collection wrapped records.
1105 Handle OPAC for record conversion module.
1107 Fixes for ICU wrapper.
1109 Allow ICU libs to be controlled with --with-icu .
1111 --- 3.0.16 2007/11/12
1113 Added yaz_poll which is a wrapper for select/poll. When poll is available
1114 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1115 sockets to be in use.
1117 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1118 functionality through an XML based configuration (ICU chain). This system
1119 is useful for search facilities such as Pazpar2 and Zebra that needs to
1120 perform tokenization of indexed material. The ICU code in a separate
1121 library libyaz3_icu.a.
1123 Added HTTP tunnel facility for COMSTACK, bug #1752.
1124 This is a facility that allows a Web proxy, such as squid, to tunnel
1125 Z39.50 traffic. This facility is "transparent" to must applications
1126 using YAZ. It's enabled by using pseudo transport connect: followed by
1127 the proxy address, followed by command, then follwed by he regular
1128 "virtual" addresss. For example,
1129 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
1131 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
1133 --- 3.0.14 2007/09/21
1135 Fixed bad memory reference in ZOOM_record - cuased by member not being
1136 initialized. This was a problem only in YAZ 3.0.12.
1138 Fixed bug in conversion from MARC to XML: Non-XML characters in control
1139 fields were not removed.
1141 Changed the way C code is generated from codetables.xml. Made a MARC-8
1142 conversion trie for each characterSet section rather than codeTable.
1143 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
1144 of codetables.xml from Larry Dixson, LOC. Bug #1464.
1146 --- 3.0.12 2007/09/12
1148 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
1149 from ZOOM_record_error).
1151 ZOOM C function ZOOM_record_get returns record schema for type="schema".
1153 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
1155 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
1157 Better SRW-to-Bib-1 diagnostic mapping.
1159 ZOOM C and yaz-client announces SRU version 1.2 by default.
1161 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
1164 Fixed in yaz_sru_decode to allow other version than 1.1.
1166 --- 3.0.10 2007/08/22
1168 Added support for SRU scan for ZOOM.
1170 Added support for the use of the older versions or Extended Service
1171 Update in ZOOM. To faciliate this, an option "updateVersion" may be
1172 set to the version , 1=first, 2=second, 3=third. The third version is
1173 what ZOOM C has used so far. And that, obviously, is the default.
1175 Added support for CCL queries in Z39.50 queries sent to the GFS (and
1176 therefore in Zebra and in SimpleServer-based applications). The new
1177 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
1178 qualifier file used to transform incoming CCL queries into Type-1 RPN,
1179 which is passed into the back-end search callback function.
1181 Added support for HTTP Basic authentication in clients: the SRU/W
1182 codec encodes the username/password elements of the PDU structure
1183 appropriately, and these may be set using the "user" and "password"
1184 options in ZOOM-C applications (the same options that are used for
1185 Z39.50 authentication).
1187 --- 3.0.8 2007/06/25
1189 Fixed bug #1208: SSL appears to be broken in ZOOM.
1191 Fixed bug #1206: Libxml2 include path weirdness.
1193 Added oid_name_to_dotstring.
1195 Allow elementSetName to be specified for ZOOM C record update.
1197 Allow waitAction to be specified for ZOOM C based for Extended Services.
1199 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
1200 syntax OID. Bug introduced in YAZ 3 series.
1202 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
1204 --- 3.0.6 2007/06/06
1206 Fixed bug #1157: yaz-client does not read .yazclientrc from current
1207 directory. yaz-client now reads commands from file given by option -f
1208 if specified; then tries to read .yazclientrc in current directory.
1209 Failing that, it reads .yazclientrc from user's home directory.
1211 Added support for correlationInfo Note and ID for Record Update via
1214 Added yaz-client command querycharset which specifies character set for
1215 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
1216 (termListAndStartPoint).
1218 Charset ISO5428:1984 is an alias for ISO5428-1984.
1220 Implemented a way to perform scan in a result set using Z39.50. This
1221 is achieved by attaching the result set name in the characterInfo
1222 (type InternationalString) of OtherInformation in the Scan Request PDU.
1223 The result set is identified in the otherinformation by the new OID:
1224 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
1225 This allows for scan in result set and faceted search . Zebra did some
1226 of this in the APT term using attribute type 8 and value being result
1227 set. Using the OtherInformation approach for this is cleaner and easier
1228 to work with in proxies and the like. This facility can be used in
1229 yaz-client using new command setscan which takes a result set as first
1230 argument, start position (APT) as second.
1232 Changed decoding of SRU XML packed records to deal with servers that
1233 have recordData with XML data with multiple root nodes. Also make
1234 comparison for recordPacking case insensitive. Again, one server
1235 returns "XML" where others return "xml".
1237 For SRU responses allow Content-Type application/xml as well as text/xml.
1239 --- 3.0.4 2007/05/21
1241 Fixed bug in character set conversion of BER strings. Bug introduced
1244 --- 3.0.2 2007/05/08
1246 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
1248 For OID class, use oid_class consistently.
1250 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
1253 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
1254 character set for bibliographic information interchange". By Giannis Kosmas.
1256 Added documentation on new OID API.
1258 --- 3.0.0 2007/05/02
1260 Changes to generic frontend server interface: added new member
1261 'query_charset' for bend_initrequest structure. A backend init handler
1262 should set this member to its native character set for query terms.
1263 When defined, the frontend server logic will announce this character set
1264 to a client if the negotiationModel bit is set by the client. All server
1265 implementors are encouraged to specify this. If a backend server does not
1266 specify this a warning is issued using yaz_log(YLOG_WARN,..).
1268 Added CCL utility to remove terms (stop words) from resulting RPN
1269 tree. This is handled by functions with prefix ccl_stop_words_ .
1271 New ZOOM C option, "rpnCharset", which allows client-side conversion of
1272 terms in RPN queries.
1274 Clean-up the CCL API. Moved some internal structures from ccl.h to
1275 private header cclp.h. Changed ccl_parser_create so that a Bibset must
1276 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
1277 This is replaced by ccl_parser_find_str which takes a string instead.
1279 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
1280 libyaz.la is the core of YAZ except the generic frontend server and
1281 does not depend on POSIX threads anymore. libyaz_server.la is the
1282 generic frontend server facilities and uses POSIX thread functionality
1283 if available. The libyaz.la no longer depends on POSIX threads because
1284 the number of global structures is limited. NMEM no longer re-uses blocks
1285 between threads ; it simply free's memory immediately but allocates in
1286 "large" chunks as usual. We don't expect any performance penalties
1287 because of this. The yaz_log system is still using a global log_level so
1288 caution must be taken when modifying it with yaz_log_init_.. +
1289 yaz_log_mask_str. This, however, should not cause any trouble because
1290 these functions are called during initialization of application code
1291 anyway. `yaz-config --libs server` returns libs for server applications;
1292 `yaz-config --libs` returns libs for non-server applications.
1294 New OID database - with public definitions in oid_db.h. Removed old OID
1295 database including the head oid.h and definitions such as enum oid_value
1296 and struct oident. The new OID database uses the same string names as
1297 before but the 'protocol' is gone. There are now only two representations
1298 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
1299 converts from string to OID; functions with prefix yaz_oid_to_string
1300 converts the other way.
1302 Change to emit_term() in CQL-to-PQF query translation: when a term has
1303 the /regexp relation modifier, do not process it for leading and
1304 trailing "^" and "*", which have quite different meanings in regular
1307 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
1308 write handlers no longer carries a 'last' parameter. This will make
1309 yaz_iconv flush "less" characters. A flush is performed by call to
1310 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
1312 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
1313 removed, because function yaz_query_to_wrbuf does the same.
1315 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
1316 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
1318 Deprecated MARC utility functions removed.
1320 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
1323 Branch split: YAZ_2_1_55_branch
1325 --- 2.1.54 2007/03/16
1327 Fix to ZOOM-C so that transparent reconnection is properly handled on
1328 connections that are in asynchronous mode.
1330 Fixed compilation on OpenBSD 4.0.
1332 Large strings in GRS-1 records are now properly displayed in yaz-client.
1334 Added character conversion support for "advancegreek"; based on patch from
1337 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
1338 sequence is met. Before the error was not set so it would be unknown.
1340 Adjust yaz-marcdump MARC reader so that it skips until record separator
1343 --- 2.1.52 2007/03/07
1345 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
1346 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
1347 fd_set structure used as a bitmask for the FDs to be selected on.
1349 Using ACX_PTHREAD macro to check for POSIX threads.
1351 Fixed have-vsnprintf check.
1353 --- 2.1.50 2007/02/23
1355 Fixes for configure on BSD. Bug #900.
1357 Added snprintf/vsnprintf wrappers for systems that don't have
1358 limits (heavens forbid).
1360 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
1361 created before all previous tasks were completed and removed from the
1362 task queue, the new task could be removed by a mistake.
1364 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
1366 Implemented pass-through CQL-to-PQF conversions. Bug #861.
1368 Fixed bug #832: Problem with MARC/charset in yaz-client.
1370 Fixed bug #668: save command line history for yaz-client.
1372 Fixed bug #830: pkg-config support.
1374 --- 2.1.48 2007/01/23
1376 Extended ZOOM result set options with two options that may be read by
1377 a client: resultSetStatus and presentStatus with values as specified for
1379 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
1381 Fixed bug #827: Using SSL fails on Debian etch.
1383 Fixed bug #826: Weird looking chars for set of MARC records.
1385 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
1386 that is treated as an ItemOrder with itemRequest being an XML document
1387 external. The value of "doc" is the content.
1389 Extended the GFS search facility. New member of bend_search_rr
1390 'estimated_hit_count' signals that hits is known to be an estmate
1391 (higher or lower than real hit count). New member 'partial_resultset'
1392 signals that the search was partial (hit count is lower or equal than
1393 real hit count). For Z39.50, the information is stored in resultSetStatus
1394 member of SearchResponse APDU. For SRU, the information is signalled
1395 via SRU diagnostic 59: "Result set created with valid partial results
1398 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
1400 --- 2.1.46 2007/01/13
1402 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
1404 Added ZOOM_connection_peek_event.
1406 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
1407 the following new functions:
1408 ZOOM_event_nonblock, ZOOM_connection_process,
1409 ZOOM_connection_get_{socket,mask,timeout},
1410 ZOOM_connection_fire_event_{timeout,socket}.
1411 The existing blocking event handler, ZOOM_event, is a wrapper for the
1412 + blocking ZOOM_event_sys_{poll,select}.
1414 Implemented function ccl_xml_config which parses XML version of CCL
1415 configuration (bug #798).
1417 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
1419 Added timings utility (yaz/timing.h)
1421 --- 2.1.44 2007/01/03
1423 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
1426 Fixed bug #779: Rotation of apdu.log fails.
1428 Fixed for character set conversions:
1429 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
1430 Honor G1 set in MARC-8 decoding.
1432 --- 2.1.42 2006/12/17
1434 Fixed bug #775: char conversion does not handle Alternative UTF-8
1437 Implemented function yaz_marc_read_line which parses MARC line format
1438 records. There is a wealth of formats out there. So far, this function
1439 reads line records produced by yaz_marc_write_line.
1441 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
1442 more generic and easier to remember(!) options: -i format and -o format
1443 which specifies input format and output format respectively - where
1444 format is one of "marc", "marcxml", "line", "marcxchange".
1446 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
1447 does not print anything except warnings for records.
1449 For yaz-marcdump, added support for MARC split into files (-s) with a given
1452 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
1453 spec, at http://www.loc.gov/standards/sru/record-update/
1454 This has changed the binary layout of the following structs:
1455 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
1456 bend_update_rr . Patch by Ko van der Sloot.
1458 Added GFS utility function bend_assoc_is_alive which returns 1 if
1459 association is still alive (client is connected); 0 otherwise (client
1460 closed connection). This allows busy servers to stop working for
1463 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
1464 been a separate piece of software. This version of ziffy has been modified
1465 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
1467 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
1469 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
1470 Client code may now interrogate options such as "init_opt_sort" to
1471 find out whether the server claims to support various options.
1473 --- 2.1.40 2006/11/27
1475 Added utilities yaz_{set,get}_esn to set/get element set name from
1478 Removed the build of libyazthread.la. The libyaz.so is the threaded version
1479 of YAZ and has been so since YAZ 2.1.10.
1481 Implemented ZOOM_record_error which returns error information for
1482 record (surrogate diagnostic).
1484 --- 2.1.38 2006/10/31
1486 Updates for SRU Update by Ko van der Sloot:
1487 1. Changed name from "operation" to "action"
1488 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
1489 versions in the code, marked as 'backward compatible'.
1490 3. Added diagnostics for SRU Update.
1492 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
1494 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
1496 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
1498 For GFS, fixed problem with SRU diagnostic 'First record position out of
1499 range' being issued for 0 hits.
1501 zoomtst10 part of Windows Build.
1503 --- 2.1.36 2006/10/13
1505 Implemented yaz_filepath_comp which splits a path into file path
1506 components (required by Zebra 2.0.3+).
1508 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
1509 BSD inspired license until now so this should not have any real impact on
1510 anybody. See http://www.opensource.org/licenses/bsd-license.php
1512 Fixed bug #687: Missing log lines.
1514 Fixed bug #678: CQL to PQF translation does not preserve double-quote
1517 Fixed bug #689: SRU diagnostics to be added.
1519 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
1520 whether a connection is idle (no more work do do).
1522 --- 2.1.34 2006/10/04
1524 Change type of optval from long to int for invocation of setsockopt with
1525 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
1527 Added support for specifying the max log file size for the Generic
1528 Frontend Server. The size is given with option -r.
1530 --- 2.1.32 2006/09/21
1532 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
1534 --- 2.1.30 2006/09/17
1536 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
1539 Fixed bug in Generic Frontend Server that could cause a server to stop
1540 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
1542 For the generic frontend server, the maximum record size is used as maximum
1543 size of incoming packages (SRU + Z39.50). The value until was previously
1544 only used in Z39.50 Init negotiation and, later, in a session controlled
1545 sizes of records returned. This is controlled using -k option. It can be
1546 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
1548 --- 2.1.28 2006/09/04
1550 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
1553 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
1555 New option for yaz-marcdump -lpos=value which allows setting a portion
1556 of MARC header to a certain value.
1558 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
1560 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
1561 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
1563 --- 2.1.26 2006/08/15
1565 Fixed problem with SRU mode type (soap, get, post) for yaz-client
1568 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
1570 --- 2.1.24 2006/08/08
1572 Fixed MARC ISO2709 encoding routines to deal with character set
1575 Minor changes to GFS logging. Database included in search request log
1578 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
1579 cached/multiple records.
1581 Shared libraries are built by default on Unix+configure.
1583 Changed cql2pqf transformation to use a different evaluation order. The
1584 new order is: always, relation, structure, position, truncation, index
1585 and relationModifier. Old order was: always, relation, relationModifier,
1586 structure, index, position, truncation. Note that the the latter ones
1587 override former ones for identical attributes.. The new scheme means that
1588 it is possible to override any existing attribute with a relationModifier.
1589 And also that it is possible to override everything for the index rule
1590 (except the ones listed in relationModifier). No order is perfect but this
1591 one, we believe, covers more real cases.. The "always" should have been
1592 called "default", since the attributes there can be overridden with all
1595 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
1596 compilation phase, but also for yaz-config --cflags output. This allows
1597 us to have public headers with Libxml2 stuff in them . It should also,
1598 eventually, make Libxml2 checks redundant in packages using YAZ, such
1601 --- 2.1.22 2006/06/15
1603 Changed SRU update structure bend_update_rr so that SRU diagnostics are
1604 stored in uri, message and details.. Previously diagnostics were stored
1605 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
1606 compatibility.. but he's probably the only one affected, so.
1608 Added support for CCL, compiled on the client side, in ZOOM-C. This
1609 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
1610 input; the resulting query objects can be used for for searching with
1611 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
1613 YAZ' configure searches for OpenSSL by default.
1615 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
1616 SL_CTX_use_certificate_file. See
1617 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
1618 for more info. Thanks to Ko van der Sloot.
1620 --- 2.1.20 2006/06/02
1622 Bug #600: SRU GET, POST support for yaz-client. Introduced
1623 command 'sru' which selects method SOAP/GET/POST.
1625 Allow missingValueAction to be specified for the sortspec string -
1626 function yaz_sort_spec. By default, the missing value action is null.
1627 Use ! to specify "abort". Use = followed by stringvalue to specify default
1630 Ensured that Present-handler (if defined) is called in GFS before any call to
1631 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
1632 searchRetrieve requests.
1634 Documentation for YAZ is now based on the Docbook XML/XSLT using
1635 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
1636 is no longer depending on jade/openjade or docbook-to-man scripts.
1637 PDF is no longer part of the distribution - but can optionally be
1638 made using DSSSL/jadetex or FOP.
1640 Added retrieval handling support in Generic Frontend Server to support
1641 conversion between MARC/XML as well as XSLTtransforms. See
1642 etc/yazgfs.xml for an example.
1644 Added Authentication support to Generic Frontend Server in SRU
1645 mode. Authentication using HTTP Basic is supported, as is the use
1646 of 'x-username' and 'x-password' parameters in the request itself.
1648 Added support for a new character set MARC8s identical to MARC8 except
1649 that it converts combined characters to single Unicode characters in the
1650 Latin-1 range (when possible).
1652 --- 2.1.18 2006/04/24
1654 ASN.1 compiler 0.4: generates brief Doxygen file header for
1655 generated .h/.c files.
1657 Utility yaz_iconv now supports conversion to MARC-8.
1659 New facilities for the MARC module. The reading - and writing of
1660 content are separate methods for the yaz_marc_t handle. The following
1661 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
1662 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
1663 format). Write functions have prefix yaz_marc_write_.. The existing
1664 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
1665 available. Removed support for OAI-MARC and simplexml (not the
1666 simplexml from PHP5).
1668 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
1669 to be returned for this connection.
1671 --- 2.1.16 2006/03/31
1673 Allow multiple languages and charsets to be specified with
1674 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
1675 negcharset iso-8859-1,utf-8
1677 Translation of proximity nodes from CQL into PQF now works.
1679 Moved to automake 1.8, 1.9.
1681 Added function yaz_log_set_handler which allows a log handler to be
1682 installed. This handler will be called for all log messages. Output
1683 to file is also produced; but that can be disabled by passing NULL
1684 fname to yaz_log_init_file.
1686 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
1688 For SRW (including GFS), accept application/soap+xml as content-type
1691 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
1692 produces NO stylesheet reference even if a default stylesheet is specified
1695 --- 2.1.14 2006/03/14
1697 Updated Windows package to include yazd.dll + yazd.lib for the
1698 Development component.
1700 If the environment variable YAZ_LOG is set, then it is used as a
1701 string indicating the default level of logging to use if not
1702 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
1703 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
1704 used as before. So, for example, to omit warnings from YAZ logging,
1705 export YAZ_LOG=-warn
1707 cql_transform() now map structure and other attributes before indexes,
1708 so that index-specific structures and other attributes can override
1709 defaults. So now a combination of mapping specifications such as:
1711 index.dc.date = 1=date-modified 4=5
1712 does the right thing.
1714 cql_transform() now also respects the "always" mapping specification,
1715 which establishes an initial set of attributes to be used for all
1716 terms except where overridden by more specific attributes associated
1717 with the index, relation or modifier.
1719 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
1720 which mode to use; one of "post", "get" or "soap" (SRW, default).
1722 Fixes for yaz_iconv routines: changed trie-based character set conversions
1723 to use only non-negative values for bit fields due to Sun's C compiler not
1724 supporting negative values.
1726 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
1727 sequences where not read correctly. Fix by Rustam Usmanov.
1729 Updated win/makefile to use options, settings which makes things
1730 compile with VS C 2005.
1732 --- 2.1.12 2006/02/01
1734 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
1736 In ZOOM socket code, use select instead of poll on MacOSX.
1738 ZOOM-C now support client-side compilation of CQL into RPN that is
1739 sent to the server, enabling CQL to be used against all Z39.50
1740 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
1741 ZOOM_query object, and submit it using ZOOM_connection_search().
1742 The CQL-to-RPN translation uses a configuration file, the name of
1743 which must be specified in the Connection's "cqlfile" option.
1745 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
1746 function, which takes as its start-term parameter a ZOOM_query object
1747 (which may have had either CQL or RPN set into it).
1750 --- 2.1.10 2005/11/29
1752 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
1753 GFS to support this as well. Backend handler, bend_srw_update, does the
1754 update work. Code contributed by Ko van der Sloot.
1756 Allow retrieval of Search Result-1 information in ZOOM by the use of
1757 options that are attached to a result set. ZOOM documentation updated
1760 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
1761 UTF-8 conversion. Patch by Raj Patel.
1763 Added option -m to GFS to control formatting of timestamps in log file.
1765 Added 'exit' as synonym for 'quit' in yaz-client
1767 Added support for specifying SRW resultSetId + resultSetIdleTime in a
1768 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
1769 for the new members. Patch by Ko van der Sloot.
1771 Added support for SRU POST. It is supported for content-type
1772 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
1774 Do not build the separate Multi-threaded (MT) library libyazthread.la.
1775 Instead make the library libyaz.la multi-threaded. Threading as a whole
1776 can still be disabled by configure option --disable-threads. Previosly,
1777 with older GLIBCs there were problems with MT libs under Apache. This
1778 has now been fixed a long time ago.
1780 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
1783 CQL module modified to be case insensitive for relations/indexes/operations.
1785 Fixed bug in CQL transform code: incorrect value relationModifieder
1788 Added 'show all' command for yaz-client which retrieves all results
1791 Added new yaz-client, xmles, which takes a (private) OID and
1792 a document to be sent as an extended service request.
1794 Describe new yaz-client commands wait_response and set_auto_wait.
1796 Increase TCP/IP listener backlog from 3 (which I am guessing was
1797 copied from the SunOS manual entry way back when) so SOMAXCONN, so
1798 that the socket will queue as many incoming connections as it's able
1799 to handle ongoing connections. In other words, it will never now
1800 refuse a connection that it would be able to handle merely because
1801 it's not got around to accepting() enough of the pending connections
1802 yet. This is the behaviour anyway under Linux, where the listen()
1803 argument is ignored; but not under BSD and on systems such as
1804 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
1805 YAZ-based servers should now be uniform across operating systems in
1808 yaz-marcdump uses 64-bit file access on some systems. This is enabled
1809 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
1810 This allows yaz-marcdump to read large MARC batches (>2 GB).
1812 Modified all YAZ source files - except the source which is auto-generated
1813 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
1816 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
1817 corresponding to the existing *_setl() function. These allow option
1818 values containing arbitrary valuues.
1820 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
1821 ZOOM_resultset_sort() in new applications. Its behaviour is identical
1822 except that it returns an indicator of whether or not the sort
1823 criterion was accepted (0 for OK, -1 for invalid).
1825 --- 2.1.8 2005/06/07
1827 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
1828 MARC output rather than returning "new" buffer.
1830 yaz-client warns about unknown init options.
1832 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
1834 --- 2.1.6 2005/05/24
1836 Added support for SRW sort in Generic Frontend Server. Patch
1837 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
1838 sortKeys - or NULL if none is provided.
1840 Fixed bug #307: It was impossible to specify indefinite/no timeout
1841 for ZOOM_event. Special timeout value -1 now means indefinite timeout
1844 Added support for multiple languages and charsets to be specified in
1845 ZOOM. Each charset/language is separated by a blank. If negotiation is
1846 in effect in init-response, Option
1847 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
1848 Code based on patch by Vasiliy Osadchuk.
1850 Fixed bug #306: infinite recursion that occurred when calling
1851 yaz_log_level_init as the first call (before other log level or
1854 Fixed bug in scan handling in front end server: if preferred-Position-In-
1855 Response was non-present, a NULL pointer referece was performed.
1857 --- 2.1.4 2005/04/26
1859 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
1860 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
1861 now defined for all those error codes. So instead of putting 109 in
1862 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
1863 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
1865 Modified the yaz-marcdump utility to skip garbage bytes between MARC
1868 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
1870 Program yaz-client now exits and produces an error message if multiple
1871 Z39.50 servers are specified on the command line (none or one allowed
1874 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
1877 --- 2.1.2 2005/03/16
1879 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
1881 Fixed bug #272: Preserve spacing for CCL terms.
1883 --- 2.1.0 2005/03/14
1885 Added support for virtual hosts and multiple backend servers for
1886 the YAZ frontend server. The configution is XML based and
1887 support specificition of CQL to RPN mappings and explain information.
1888 See section "Virtual Hosts" in the YAZ manual.
1890 Extended OPAC display utility. OPAC display utility renders
1891 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
1892 to supplement yaz_marc_decode_wrbuf.
1894 Fixed a bug in MARC decoder that could caused it to crash for some
1895 invalid MARC records. More diagnostics and warnings where added in
1896 XML output (warnings, etc are stored in comments).
1898 --- 2.0.34 2005/02/08
1900 Fixes for UNIX domain sockets. Bug #261.
1902 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1904 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1905 Added yaz_marc_subfield_str which defines subfield lead string which is
1906 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1907 yaz_marc_endline_str which defines end of fields string used in
1908 YAZ_MARC_LINE format. Default string is newline.
1910 Experimental support for MarcXChange. This format can be produced
1911 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1912 http://www.bs.dk/standards/MarcXchange.xsd
1914 Added yaz-client commands scansize that sets maximum number of
1915 entries to be returned by scan.
1917 --- 2.0.32 2005/01/11
1919 Added support for SRW scan in yaz-client and Generic Frontend Server.
1921 * Added whereInList member to SRW Scan Term.
1923 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1925 Fixed NMEM system to return aligned blocks on the smallest boundaries
1926 that are suitably aligned for all possible types on the particular
1927 architecture YAZ is being built for.
1929 --- 2.0.30 2005/01/04
1931 Fixed numerious warnings that was issued with newer versions of GCC.
1933 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1934 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1937 Make YAZ Generic Frontend Server slightly faster.
1939 Enhance (and reduce) logging for Generic Frontend Server.
1941 Revert YAZ log system so that it flushes every write operation
1942 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1944 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1945 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1946 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1947 will effectively disable old definitions.
1949 --- 2.0.28 2004/11/09
1951 Added yaz_log_time_format which specifies log format using
1954 Added yaz_log_module_level which returns mask for a module. Value
1955 is non-zero mask a if module is enabled; zero if disabled.
1957 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1958 in include/yaz/cql.h.
1960 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1962 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1964 Fixed bug #172: RPM builds does not enable SSL.
1966 Doxyfile.in part of dist. Doxyfile generated by configure.
1968 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1969 are given and the corresponding component does not exist.
1971 Extend CCL documentation in YAZ reference. Describe r=r.
1973 --- 2.0.26 2004/10/01
1975 Fixed MARC->MARCXML conversion to properly deal with
1976 fields, subfields, indicators having non-ASCII characters.
1978 Fixed MARC->MARCXML conversion so that ASCII control characters
1979 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1982 Added YAZ GFS support for conversion from Z39.50 surrogate
1983 diagnostics to SRW surrogate diagnostics.
1985 Bug fix: YAZ GFS did not return schema in explainResponse.
1987 --- 2.0.25 2004/09/30
1989 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1990 now converts recordSchema to elementSetName as well as schema URI.
1992 Fixed bug in COMSTACK that prevented HTTP request packages from being
1995 --- 2.0.24 2004/09/29
1997 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1998 does not require white-space before and after the dash in a range, e.g.
1999 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2002 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2003 due to new GCC removing "redundant" code.
2005 Added yaz-client commands scanpos and scanstep that sets preferred
2006 position and step-size for scan.
2008 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2010 Added CCL utility ccl_qual_buf which parses one or more CCL
2011 spec lines in a buffer.
2013 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2014 of name and value - ignoring empty lines and comments.
2016 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2018 Added odr_get_element_path which returns current element path for an
2019 ODR handle. This utility is useful in error handling or user-defined
2022 Added ODR_PRINT utility odr_set_stream which is is a more generic
2023 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2024 to a write function and pointer to close function. The close function - if
2025 non-NULL - will be called during odr_destroy.
2027 Fixed bug in CCL parser where truncation char was not removed from
2028 right side when truncation=both was in effect.
2030 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2033 --- 2.0.23 2004/08/11
2035 Fix buffer overrun in CQL parser when dealing with proximity (%).
2037 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2038 to UTF-8/UCS conversion is now only based on codetables.xml.
2040 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2042 --- 2.0.22 2004/08/06
2044 Add support for more "commit changes" in ZOOM (uses Extended Services).
2046 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2049 Yet another small fix for configure of SSL.
2051 --- 2.0.21 2004/05/14
2053 Fix SSL libs for configure when --with-openssl=DIR is given.
2055 --- 2.0.20 2004/05/10
2057 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2059 SSL comstack now uses yaz.pem certificate file on server side
2060 by default. Certificate filename can be configured by calling
2061 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2063 Fix bug regarding multiple calls to ZOOM_connection_connect.
2065 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2067 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2068 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2070 ZOOM now allows inspection of X509 peer certificate for verification.
2071 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2073 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2074 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2075 as "modular" but it simplifies things.
2077 Added cs_get_peer_certificate to that returns peer X509 PEM.
2079 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2080 NULL if SSL is unavailable.
2082 Documentation about MARC decoding tools.
2084 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2086 --- 2.0.19 2004/03/30
2088 Rename CHANGELOG to NEWS to follow GNU style packing.
2090 Fix bug with missing initialization of member in init_diagnostics.
2091 This bug affects threaded version of GFS server.
2093 --- 2.0.18 2004/03/20
2095 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2098 Ensure zlib.dll is packed with Windows install.
2100 --- 2.0.17 2004/03/17
2102 Fix encoding of xsd:string to use text instead of CDATA.
2104 Fix endless loop in CQL parser with unbalanced ".
2106 Use a more compact way to store MARC-8 conversion tables.
2108 --- 2.0.16 2004/03/16 Debian only
2110 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2113 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2118 --- 2.0.15 2004/03/01
2120 Another fix for decoding of XML packed records.
2122 --- 2.0.14 2004/02/25
2124 Fixes for Chunked encoding. White space not ignored after length spec.
2126 Update NS and use default NS for SRW diagnostic elements.
2128 --- 2.0.13 2004/02/23
2130 Implement ZOOM_resultset_cache_reset which resets record cache.
2132 Implement ZOOM_resultset_sort which sorts a result set.
2134 Implement chunked HTTP transfer.
2136 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
2138 --- 2.0.12 2004/02/16
2140 Added member 'schema' to bend_explain_rr structure so that backend
2141 can specify explain record identifier. Defaults to Zeerex 2.0.
2143 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
2145 --- 2.0.11 2004/02/16
2147 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
2150 Added init command for yaz-client which sends "extra" init request.
2152 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
2153 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
2155 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
2157 Make ZOOM error code for "invalid query".
2159 Fixed compilation for SSL which wasn't properly enabled for all platforms.
2161 --- 2.0.10 2004/02/05
2163 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
2166 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
2168 Added option -p <file> to make Generic Frontend Server to write PID file.
2170 Added option -D to put Generic Frontend Server in background on its own.
2172 Make ZOOM C recognize option "password". If unset, "pass" is used
2173 (for backwards compatibility).
2175 Fixed a bug in Generic Frontend Server that could make it crash if a
2176 client sets characterSetNegotation bit, but didn't pass negotiation stuff
2179 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
2180 Must be issued before open, in order to be in effect.
2182 --- 2.0.9-6 2004/01/12 Debian/Windows
2184 Make the SRU server more picky WRT unknown params, etc.
2186 Bug fix: ZOOM scan response didn't return displayTerm - when present.
2188 New YAZ client command, options, that sets Z39.50 options.
2190 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
2191 options from a string of tokens (one token for each option bit).
2193 Update SRW diagnostic code messages.
2195 --- 2.0.9-5 2004/01/07 Debian/Windows
2197 Handle user defined stylesheet for SRW/SRU.
2199 --- 2.0.9-4 2004/01/06 Debian/Windows
2201 Fix bug in decoding of Content-Length.
2203 --- 2.0.9-3 2004/01/06 Debian/Windows
2205 Fix a bug with decoding of XML packed records.
2207 --- 2.0.9-2 2004/01/05 Debian only
2209 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
2211 Fix bug in SRW/SRU diagnostics decoding.
2213 --- 2.0.9 2004/01/05
2215 Fixed bug in Generic Frontend Server which could drop records exceeding
2216 preferred message size. Reported and fixed by Irina Dijour.
2218 Fixed calculation of package size for structured records in Generic
2219 Frontend Server. Reported and fixed by Irina Dijour.
2221 Fixed namespace for SRW/SRU diagnostics.
2223 Fixed SEGV in yaz-client that occured for HTTP connection errors.
2225 --- 2.0.8 2003/12/22
2227 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
2228 this version is incompatible with version 1.0 and older YAZ SRW/SRU
2231 CQL changes to reflect recent changes to the specification:
2232 * Documentation talks about context sets instead of index sets.
2233 * Documentation talks about indexes instead of qualifiers.
2234 * The CQL-to-PQF transformer's configuration file now uses
2235 "index.set.name = <attributes>" instead of the old form
2236 "qualifier.set.name = <attributes>". (Both forms are still
2237 understood but the latter is deprecated.)
2238 * CQL terms with no explicit index specified are now interpreted as
2239 cql.serverChoice instead of srw.serverChoice (which of course
2240 behaves exactly the same.)
2242 --- 2.0.7 2003/12/16
2244 MARC conversion can now generate ISO2709 output in another
2245 character set. yaz-marcdump uses this facility if you invoke it
2248 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
2249 functions from there can be used from C++.
2251 --- 2.0.6 2003/12/04
2253 Frontend server now transfers memory from decoded packages to stream
2256 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
2257 references to show up.
2259 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
2260 the ZOOM Abstract API. The older names for the same options are still
2261 also supported for the benefit of old applications.
2263 ZOOM-C supports "implementationId" and "implementationVersion" options
2264 to go along with "implementationName". These allow the user code to
2265 specify identification strings to be sent to servers.
2266 Add OID for the new ExtLite attribute set.
2268 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
2269 as requested/supplid by Ere Maijala <ere@atp.fi>
2271 For generic frontend server, reverse the order of
2272 "toolkit-supplied / application-supplied" strings sent as implementationId,
2273 Name and Version. Also, remove the spaces around the slash. This brings
2274 the GFS in line with the behaviour of ZOOM-C on the client side.
2276 Add function ZOOM_scanset_display_term.
2278 yaz-client shows scan displayTerm if present.
2280 Utility yaz-iconv is now installed by default along with the man page
2283 Extend configure check for OpenSSL to use pkg-config where available (such
2286 Incorporate patch by Morten Bogeskov which allows a Unix file socket
2287 server to specify uid/gid/mask for socket using the format
2288 unix:[user=uid,][group=gid,][umask=mask,]file=path
2289 If file= is omitted the existing format is assumed, e.g.
2291 in which case the mask is 0666 (rw for everybody).
2293 Major restructure of YAZ source. All source in libyaz is in src directory.
2294 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
2295 util (utility programs such as ASN.1 compiler, yaz-marcdump).
2297 Added man page for utility yaz-marcdump (used to be called marcdump).
2298 yaz-marcdump is installed by 'make install'.
2300 Fixed a memory leak in Generic Frontend Server that occurred when decoding
2301 of incoming package failed.
2303 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
2305 Change prototype of odr_perror: add const to message string.
2307 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
2309 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
2310 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
2311 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
2312 DNS lookup. There should not be any compatibility problems with this
2313 assuming that blocking=1 or 0 is used.
2315 Fix bad reference in UNIX comstack in function cs_addrstr.
2317 Fix for compilation on AIX.
2319 The generic front-end server (server/seshigh.c) now supports returning
2320 Init diagnostics to the client in User-information-field, in
2321 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
2324 --- 2.0.4 2003/09/04
2326 Allow any CQL relation (not just all,any,exact,scr).
2328 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
2329 that features the same UI.
2331 Implemented command update0 in YAZ client which is equivalent to
2332 update but uses old of Ext Update ASN.1.
2334 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
2335 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
2336 Previously no OID was used for this info.
2338 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
2339 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
2340 returns 'malformed search term' otherwise.
2342 SortResponse member resultCount now set to NULL in sort handler of
2345 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
2348 Add three new utility functions for translating OIDs between various
2349 formats -- symbolic name such as "Usmarc", minus-1-terminated int
2350 arrays and dotted strings such as "1.2.840.10003.9.5.1":
2351 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
2352 char *oid_to_dotstring(const int *oid, char *oidbuf);
2353 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
2355 Reverted modifications for ES Update definition for z_IU0Update
2356 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
2357 is back to YAZ 2.0.2.
2359 String value attributes for CCL parser.
2361 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
2362 which their FirstSearch server returns in Init responses, sometimes
2363 carrying useful diagnostic information when Init fails. This has the
2364 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
2365 "z39.50/oclcui.asn", where its definition is somewhat different from
2366 what OCLC document on their web-site, as required to interoperate with
2369 Support for anonymous authentication in yaz-client. Use the command
2372 * Fix the OID of the Index Data-local "admin" Extended Service from
2373 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
2374 the 1000, which indicates a locally-defined OID, was a mistake.
2376 --- 2.0.3 2003/06/20
2378 Fix CCL directive @case handling so that it affects string match for
2379 both CCL keywords and qualifiers.
2381 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
2382 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
2383 Decoder has been updated with ASN.1 changes as listed in
2384 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
2385 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
2386 z_IUUpdate, remains unchanged.
2388 ZOOM_record_get may now return a record in a specific character set.
2389 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
2390 "from" is the character set of record as returned by target. "to" is
2391 the character set to be returned. If omitted, "to" is UTF-8.
2393 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
2395 New ODR utility, odr_getelement, which returns name of element for
2396 which encoding/decoding failed.
2398 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
2399 in cases where a required element was omitted.
2401 Bug fix: some MARC8 sequences were not converted.
2403 New ZOOM option "step" which specifies number of records to be
2404 retrieved in one chunk. Used in conjunction with "start" and "count".
2406 SRW support for yaz-client. Use scheme http: to use it, e.g.
2409 yaz-client no longer does (un)intelligent character set conversions
2410 by default. Can be enabled with charset and marc_charset commands.
2412 xmalloc trace fix for 64-bit systems such as DEC alpha.
2414 Solaris 2.6 compile fix.
2416 New function, cql_strerror() translates SRW error codes, as returned
2417 by cql_transform_error(), into human-readable English strings. Used
2418 in yaz-client diagnostics when appropriate.
2420 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
2421 converts it into a type-1 query which is sent to the server. This
2422 makes CQL available for use with all Z-servers, as opposed to the tiny
2423 minority that can handle CQL queries themselves.
2425 --- 2.0.2 2003/04/28
2427 New Debian package layout similar to the Redhat Package layout.
2429 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
2430 and search result respectively.
2432 --- 2.0.1 2003/04/25
2434 Redhat package is now several packages: libyaz (runtime libraries),
2435 libyaz-devel (development and documentation, and yaz (utility programs).
2436 Package spec file by Morten Bogeskov.
2438 New member 'schema' in struct bend_fetch_rr which the name of requested
2439 schema (SRW/SRU) for record (or NULL if none was given). The fetch
2440 handler MAY set this to reflect the schema of the returned record.
2442 New member 'display_term' in struct scan_entry. GFS now sets member entries
2443 and allocates scan entries to be filled by user scan handler. In previous
2444 version, entries member was allocated by the scan handler. That still works,
2445 but the GFS will ignore member display_term - assuming it was NOT set by
2446 the handler. The fact that the GFS now allocates the entries both allows
2447 for new members and makes a scan handler easier to write.
2449 Fix CQL lex buffer overflow.
2451 SRW/SRU recordPacking. For SRW default recordPacking is string. For
2452 SRU default recordPacking is string.
2454 SRU protocol support for frontend server.
2456 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
2458 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
2460 Added scan for the ZOOM shell (zoomsh).
2464 * String Identifers for Schemas (Amendment 5).
2465 http://lcweb.loc.gov/z3950/agency/amend/am5.html
2466 Old definition for schema
2467 Odr_oid *schema; /* OPT */
2472 Z_InternationalString *uri;
2473 #define Z_Schema_oid 1
2474 #define Z_Schema_uri 2
2477 * resultCount parameter to Sort Response (Amendment 1).
2478 http://lcweb.loc.gov/z3950/agency/amend/am1.html
2480 Support for SRW 1.0 over HTTP. This is an optional feature and
2481 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
2484 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
2485 on the same port. SRW SearchRetrieveRequests are mapped
2486 to bend_init,bend_search,bend_fetch,bend_close.
2488 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
2490 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
2491 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
2493 ZOOM connections are SRW based if schem http is used for hostname
2494 in connect, e.g. z = ZOOM_connection_new("http://myserver");
2495 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
2497 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
2498 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
2499 distance=n, order=true/false, relation=le, prox unit=word. If
2500 n is omitted, distance 1 is used.
2502 Fixed problem with C compiler include path in wrong order.
2504 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
2505 on Solaris. Patch from Ko van der Sloot.
2507 New MARC decode API. All new functions operate on a yaz_marc_t
2508 handle. The most important new functions are: yaz_marc_create,
2509 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
2510 decode and destroy respectively. Decoder can produce formats
2511 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
2512 include/yaz/marcdisp.h.
2514 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
2515 to UTF-8, UCS-32, wchar_t or Latin-1.
2517 * Prototypes for yaz_iconv_-functions moved to separate header
2518 include/yaz/yaz-iconv.h.
2520 Make a few private functions 'static' in unix.c. This prevents
2521 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
2523 For ZOOM connection, the options targetImplementation{Id,Name,Version}
2524 are set when Init Response is received.
2526 New function ZOOM_connection_error_x similar to ZOOM_connection_error
2527 but returns diagnostic set as well.
2529 New function yaz_strerror which is a portable wrapper for
2530 strerror/strerror_r/GetLastMessage.
2532 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
2533 is returned for MARC. If type is "oai", then OAI MARC is returned.
2535 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
2538 --- 1.9.2 2002/11/26
2540 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
2542 Fix bad race conditions on SIGTERM and terminate gracefully in
2545 Move retrieval (data1) module to Zebra since nobody seems to be
2548 Add GRS-1 render for ZOOM using same format as yaz-client.
2550 --- 1.9.1 2002/10/05
2552 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
2554 Fix broken ESpec handling in data1 module.
2556 SGML reader parses comments and makes them part of the data1 tree.
2558 Added several type casts so that YAZ compiles as C++ code.
2560 ZOOM didn't handle PDU encoding failures properly.
2562 Added more Bib-1 diagnostics (approved extensions).
2564 GNU configure: better check for iconv.
2566 More portable use of accept, getpeername. Check for socklen_t. Use
2567 int/size_t if socklen_t is not defined.
2571 PQF parser rejects bad queries - including those with extra
2572 characters in them. PQF parser used to silently ignore that.
2573 Cleaner API for PQF added, which allows you to get detailed
2574 error information for bad queries (see yaz/pquery.h).
2576 Fixed bug in ZOOM_record_get for type "database".
2578 Implemented mini iconv library supporting conversions between
2579 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
2581 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
2583 --- 1.8.9 2002/08/20
2585 Fixed ZOOM C record cache so that preferredRecordSyntax and
2586 elementSetName is used to check for already fetched records.
2588 --- 1.8.8 2002/08/02
2590 Added three members in bend_initrequest structure to facilitate
2591 character set negotiation.
2593 Fixed a bug in frontend server that could cause indefinite
2594 loops under rare conditions.
2596 Revised character set utilities (charneg.h) so that encoding
2597 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
2599 For PQF, directive @term <type> sets term type for Scan/Search.
2600 Here <type> is general, string, numeric, null. The term type
2601 is inherited - just like @attr.
2603 New call odr_set_charset that sets character set conversion for
2604 international-strings on a ODR stream. Prototype is:
2605 int odr_set_charset(ODR o, const char *to, const char *from);
2606 The InternationalString is still represented as C string in YAZ
2607 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
2608 won't). On the protocol level, you can use any encoding.
2610 Support for UNIX sockets in ZOOM.
2612 Solaris recv sometimes returns errno == ENOENT. It is treated as
2613 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
2615 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
2616 both client and server. Code by Morten Bogeskov.
2618 --- 1.8.7 2002/05/22
2620 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
2621 that they can be used directly from Visual Basic. You must recompile
2622 your windows APP if you're using ZOOM.
2624 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
2625 Commands "lang" and "charset" sets language and character set respectively.
2626 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
2627 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
2629 Attributes from multiple CCL fields may be OR'ed rather than merged
2630 using directive "@field or". Fields are still merged by default -
2631 equivalent to "@field merge".
2633 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
2636 Fixed bug in zget for parameter ExtendedServicesResponse.
2640 --- 1.8.6 2002/03/25
2642 Added PQF feature: '@attr type=value' may be written as '@type=value'.
2644 Client displays USR.1:SearchResult-1 (hits per term).
2646 Additional Search Info for search in Generic Frontend Server.
2648 Fixed CCL parsing of "field=s".
2650 WIN32 installer - using the excellent NSIS software from nullsoft.
2652 Fixed CCL parsing of "field = - <number>".
2654 Added function yaz_marc_decode that decodes MARC for line mode
2655 display or XML (similar to that used by JZKit).
2657 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
2658 Z39.50. But ISO/ILL was, however.
2660 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
2661 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
2663 http://lcweb.loc.gov/z3950/agency/amend/am2.html
2664 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
2666 --- 1.8.5 2002/02/03
2668 New YAZ client features: Command completion and new commands:
2669 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
2670 Code provided by Jacob Poulsen.
2672 New call oid_trav, that visits all registered OIDs via callback.
2674 Function ZOOM_record_get now returns const char pointer rather than
2675 void pointer. It saves a lot of type casts.
2677 For YAZ client, command "auth" now allows you to set authentication
2678 in IdPass style. It is enabled when three tokens are given - order
2679 is user, group and password.
2681 Fix memory leaks in MARC record handling for ZOOM.
2683 New option for YAZ client, -k <kilobytes> that sets
2684 maximum record size. Similar to -k option for generic frontend
2685 server and yaz-ztest.
2687 More fixes for scan. Non-zero stepSize handled. OID's fixes.
2689 Prefix query parser reports "fail" when bad attribute set is given.
2691 Fix in MARC decoder. Proximity logging. Fix for attribute set
2692 in scan handler for server. Patches by Shigeru Ishida.
2694 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
2697 Configure option --with-openssl=<dir> now works when a directory is
2698 specified. Patch provided by Morten Bogeskov.
2700 New option for YAZ client, -u <auth>, that sets authentication.
2702 ZOOM fix: error information was sometimes "missing", since error
2703 was cleared/reset too when it shouldn't.
2705 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
2707 --- 1.8.4 2002/01/04
2709 Scan for ZOOM API. New object ZOOM_scanset. New functions
2710 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
2711 ZOOM_scanset_destroy.
2713 New ZOOM function, ZOOM_connection_last_event, that returns type
2714 of last event (such as "receive data", "send data", "apdu received",
2717 New ZOOM option, schema, that specifies schema for retrieval.
2719 New CCL feature. Qualifiers can be aliases for one or more
2720 other qualifiers (if more than one is given, OR is used).
2722 ZOOM uses named result sets if target supports it.
2724 Two new YAZ client commands: . (dot, which sources a script of YAZ
2725 client commands), and ! (to execute shell command.). Implemented
2728 Working on Debian packages.
2730 --- 1.8.3 2001/11/19
2732 YAZ client enables named result sets only if target supports it.
2734 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
2736 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
2737 with key="host" to get same result.
2739 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
2740 Function Z3950_resultset_record(s) returns references to records
2741 "owned" by resultset. To become owner use Z3950_record_clone.
2743 Function z_ext_record handles Extended Services. Thanks to
2746 --- 1.8.2 2001/11/12
2748 CCL Parser fix: ignore token comma when dealing with and-lists.
2750 Documentation updates for COMSTACK.
2752 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
2753 Changed prototype Z3950_records. For some functions, int parameters
2754 were changed to size_t.
2756 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
2759 New MARC decode/display function, marc_display_exl, which properly rejects
2760 non-ISO2709 records. YAZ client uses it.
2762 --- 1.8.1 2001/10/29
2764 Fix bug: local attribute set wasn't set correctly in PQF strings.
2768 * Old Z39.50 codecs no longer supported.
2770 Added ZOOM C binding. See http://zoom.z3950.org/
2772 Renamed states for COMSTACKs to avoid confusion with events.
2774 Implemented cs_look and proper cs_rcvconnect.
2776 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
2778 Configure detects POSIX threads on OpenBSD.
2780 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
2781 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
2783 When error is returned from present handler, non-surrogate diagnostic
2784 is returned in present response (and fetch handler is no longer called).
2786 * Minor adjustments to pquery parser (PQF). Token characters may be
2787 escaped by using backslash (C-style).
2789 PQF parser allows string attribute values to be specified. For @attr,
2790 non-numeric characters after the equal-sign are treated as strings
2791 (e.g. @attr 9=title).
2793 CCL trunction character may be defined (@truncation in file)
2795 * function zget_ExtendedServicesRequest sets waitAction to
2796 waitIfPossible (was wait).
2798 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
2801 CCL operator names may be set in field definition files (CCL_bibset).
2802 See ccl/bib1 for an example.
2804 Fixes in ASN.1 compiler for C++ compatibility.
2806 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
2807 and "op_or" to avoid conflict with C++.
2809 Fixed problem with GNU readline detection on Redhat 7.0.
2811 Added step-size for Scan backend handler.
2813 Fixed bug that made the frontend server crash when no attribute
2814 set was specified for scan.
2816 Front-end server automatically switches to original working directory
2817 when installed as an NT service. Previously -w had to be specified to
2820 Added extended attributes for retrieval module (data1), so that data1
2821 records carry d1_readXML/SGML attributes. d1_read also supports
2822 null-data rules ( <tag/>)
2824 On UNIX when POSIX threads are available, a separate library libyazthread
2825 is created. Programmers should link with that library and the yaz library
2826 when using threads. The reason for the split was that some applications
2827 on Linux, such as Apache, doesn't work well when using shared objects that
2830 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
2831 (or any frontend server) in SSL mode by specifying ssl: followed by
2832 address. Only tested on UNIX.
2834 Added feature for CCL module. Virtual structure s=al or s=ol generates
2835 and-list and or-list respectively instead of phrase search.
2839 * Added prefix "yaz_" for the functions log_init.., log_file.. and
2840 log_mask_str. This was done to avoid name conflicts with other libraries
2841 (such as other PHP extensions).
2843 Added raw OID member for preferred record syntax (request_format_raw)
2844 and returned record syntax (output_format_raw) for backend fetch method.
2846 Config file yaz-config now accepts options so that it returns specific
2847 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
2849 Shared library support for UNIX using GNU libtool.
2851 * Modified backend interface. Request/Response struct's replaced by
2852 one read/write C struct. For example bend_fetchrequest and
2853 bend_fetchresult have been replaced by single bend_fetch_rr struct.
2854 Every handler - even search has to be registered in bend_init
2855 handler. This means that the YAZ library no longer refers to
2856 external functions and it makes it possible to make the whole
2857 thing a single DLL/SO.
2859 Added Segment handler for backend server.
2861 Added Zmbol/Zebra administrative functions to YAZ client.
2863 Threaded frontend server on UNIX (when POSIX Threads are available).
2864 Starting the server with option -T enables multi-threading.
2868 Added configure option --enable-comp/disable-comp to control use
2869 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
2870 located in sub directory asn.
2872 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
2873 in ${exec_prefix}/bin along with the other programs yaz-client and
2876 GNU automake used to maintain makefiles.
2878 Added several OID's.
2880 Changed retrieval module so that we can load records with no abstract
2881 syntax defined. Tagpaths in these records are fully composed of string
2884 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
2888 On UNIX, the generated makefile now supports a proper 'make install'.
2889 The prefix can be set via GNU configure to set the install location
2890 (default is /usr/local).
2892 * YAZ programs client and ztest were renamed to yaz-client and
2893 yaz-ztest to avoid conflicts when users install YAZ in "standard"
2894 locations, such as /usr/bin,/usr/local/bin,etc.
2896 * YAZ Header files were moved from include to include/yaz. YAZ Header
2897 files are referred to as include <yaz/log.h> rather than <log.h>.
2898 The YAZ include path (-I ..) is therefore the same as before. Programmers
2899 should update their #include statements or use -Ipath/include/yaz
2900 instead. The main motivation for doing this change is that YAZ header files
2901 can be installed in "standard" locations /usr/include,/usr/local/include
2902 without introducing conflicts, since ALL YAZ header files are stored
2903 in subdirectory yaz (under /usr/include for example).
2905 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2906 rather than project/workspace files. We switched because project files
2907 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2910 Changed name of logging function, logf, to yaz_log, to prevent name
2911 clash with some math-log functions. The YAZ header log.h defines logf
2912 to yaz_log (#define) so there should be no incompatibilities by this
2915 Added bend_start/bend_stop handlers for server. These handler are
2916 called on start/stop of server. For windows they are called whenever
2917 a service is started/stopped.
2919 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2920 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2921 in util/yc.tcl. The auto-generated C code structures are, in a few
2922 cases, incompatible with the old decoders. There are differences in the
2923 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2924 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2925 The preprocessor variable ASN_COMPILED is defined when the compiled
2926 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2927 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2928 wish to use the old encoders/decoders you can specify --disable-yc
2931 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2932 version so that it supports both new - and old version of DB Update
2934 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2935 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2936 change. The name parameter can be set to 0 in which no name is specified
2937 for the construction. The macros odr_implicit and odr_explicit sets name
2938 parameter to zero for the construction involved. New macros
2939 odr_implicit_tag and odr_explicit_tag are similar to the others,
2940 except that a name parameter is added. For programmers' that don't use
2941 ODR they probably only need to change the call to z_APDU and z_External.
2943 Added access control facility by interfacing the TCP wrapper library.
2944 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2945 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2946 name of the daemon and enables the access control as specified in
2947 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2949 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2950 den Dool <H.M.vdnDool@kub.nl>.
2952 Added reference ID parameter to most functions in server API - refer
2953 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2955 Changed name of ccl library to libccl.a (was ccl.a).
2957 Fixed bug in decoder for Explain (Category TargetInfo).
2959 Added support for GNU readline in client. Thanks to Jacob Poulsen
2960 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2962 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2963 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2964 IMPLEMENTATION! This change was made to the development version before
2965 the ZIG decided to retract the amendment. If any users MUST be
2966 compatible with the original Update definition, PLEASE CONTACT US, and
2967 we will include a separate definition corresponding to the old Update
2968 ES. Note that because of the change to the ASN.1 of the
2969 TaskPackageRecordStructure we cannot define a single structure that
2970 will support both versions.
2972 * Added const modifier to buffer parameter for some ODR/BER encoding
2973 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2974 completeWAIS, odr_dumpBER.
2976 Fixed bug in client.c which caused a crash when a scanResponse didn't
2977 contain positionOfTerm.
2979 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2980 * will cause an error in a client if a non-YAZ target sends both a
2981 * list of Scan entries and non-surrogate diagnostics.
2983 Retrieval module enhancements. Tag sets may be typed in the reference
2984 to it. From the .abs-file the "tagset" directive takes a third optional
2985 integer type for the tag set referenced. From a .tag-file the "include"
2986 directive takes a third optional type as well. The old "type" directive
2987 in the tag set itself is still recognized but acts as the default type
2990 Backend interface change. Individual Scan terms returned from bend_scan
2991 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2992 in include/backend.h.
2994 Retrieval module enhancements. Multiple tag sets and attribute sets may
2995 be specified in abstract syntax specs. Revised the error/warning for
2996 logging messages reported by the retrieval module when reading the
2999 Object Identifier system (oid_..) changed. The API is backwards
3000 compatible but the oid-routines now allocates new OID's when needed.
3001 Raw OID's may be specified in oid_getvalbyname.
3003 YAZ now uses GNU configure to generate Makefile(s).
3005 * Minor changes in some of the member names of DeleteResultSetRequest and
3006 DeleteResultSetResponse. See include/proto.h.
3008 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3009 and added member 'languages' in TargetInfo (which was missing).
3011 Changed the way attribute sets are handled in the retrieval
3012 module. These are now cached, just like the abstract syntaxes
3015 Changed YAZ so that it links with compiled ASN.1.
3017 Added Explain-schema definitions and mapping routines. The following
3018 Explain categories have been implemented: AttributeDetails,
3019 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3021 Fixed minor bug in Windows version of Server Library.
3023 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3025 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3027 Added EXTERNAL: UNIverse Resource Report (non-standard).
3029 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3030 ENUMERATED and SET OF.
3032 * Added 'const' to some of the char pointer arguments for the
3033 functions, data1_read_node, data1_getelementbytagname,
3034 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3037 Fixed bug in data1_insert_taggeddata - the last_child member of
3038 parent wasn't initialised.
3040 * Changed data1_read_record and data1_read_node so that the supplied
3041 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3042 doesn't refer to any parts of the "SGML"-buffer.
3044 Fixed bug in server library (Windows version of statserv_remove).
3046 * Changed code so that it compiles as C++. The type definition
3047 of Odr_fun which is a member of Odr_arm was changed. The result is,
3048 that an explicit typecast is needed for the fun pointer when
3049 using Odr_arm - as in:
3050 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3052 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3054 Implemented the new structured date and time definition as approved
3055 by the ZIG. Added schemaId element to the specificTag in Espec-1
3056 (also approved at the last ZIG). Thanks to RVDM.
3058 Added some Object identifiers (RVDM).
3060 Changed the Update Extended Service (RVDM).
3062 Added command "refid" to client which specifies referenceId for
3063 the following requests.
3065 Implemented extended service handling for server. See ztest.c
3066 for an example as well as backend.h. New handlers are registerd
3067 in the Init handler.
3069 * Changed interface for sort in server.
3071 Added new members to statserv_options_block. It allows a server
3072 to read options from another source than just the command line. Thanks
3073 to Charles Woodfield.
3075 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3076 renamed to zboolean. Some C++ compilers complained about the name.
3078 Minor changes to gils.abs. Added index 's' (sort) on title
3079 and date/time-last-modified.
3081 --- 1.4pl2 1998/1/30
3083 Fixed bug in server library regarding inetd mode (-i). This bug
3084 was introduced by release 1.4.
3086 --- 1.4pl1 1998/1/29
3088 Added sort facility in client and backend server interface.
3090 Fixed problem with dependencies in Makefile(s).
3092 Fixed bugs for encoders/decoders of extended services and
3095 Implemented sub-tree feature for schemas. Sub-trees are
3096 referenced in *.abs-files. See explain.abs for an example
3097 of the use of this feature.
3099 Modified bib1.att; local attributes for ANY didn't include
3100 ANY itself (only affects use of the retrieval module).
3102 Fixed bug in plain SGML reader in function data1_read_node:
3103 tags with prefix "var" was incorrectly interpreted as variants.
3105 Added feature "sub-schemas" to enable references to - and definitions
3106 of - group of elements.
3108 * Removed member parent from type data1_element (in data1.h).
3110 Implemented function odr_nullval() that returns the value of
3113 * Removed member num_children from data1_node (in data1.h).
3115 Made NT service interface part of the server library. The
3116 function statserv_main uses the NT service when required and
3117 calls the statserv_start / statserv_close routines.
3119 Routine zget_SearchRequest and zget_PresentRequest fills
3120 resultSetName/Id member with "default" instead of "Default".
3122 Fixed memory leak in server. Request queue member wasn't freed.
3124 Fixed nmem_exit so that memory is freed.
3128 Revised the CCL parser utility to be thread safe.
3130 Added function, oid_ent_to_oid, to replace the function
3131 oid_getoidbyent, which is not thread safe.
3133 * Added nmem_init and nmem_exit to initialize and release
3134 NMEM resources. Function nmem_init should be called once in the
3135 initial thread before NMEM/ODR is used. statserv.c and client.c
3136 have been changed accordingly. The change was necessary to make
3137 NMEM thread safe. The NMEM memory pool is shared amongst threads
3138 in a process. Unix-based applications will still work fine without
3141 Added NT Services interface for the the Z39.50 (statserv) Server.
3142 Refer to the ztest.c source on the usage.
3144 Windows 95/NT port using MSVC5.0. Project files are included in the
3147 * Defined new 'global' handle for the retrieval (data1) system. The
3148 new handled, data1_handle, describes the state of the data1 system.
3149 This handle is passed as first argument to virtually all
3150 data1 related routines. The functions data1_create and data1_destroy
3151 creates and destroys a data1 handle respectively.
3153 Added ODR encode stream member to all backend request structures
3154 init, search, scan etc. This stream should be used to allocate all
3155 memory used for the response when thread safe operation is needed.
3157 Changed the comstack utility, cs_addstr, to be thread safe. The
3158 returned hostname string returned by the function is now part the
3161 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
3162 function. The cs_straddr takes a COMSTACK handle as argument, so this
3163 function must be used after cs_create and before bind/connect.
3164 This function is thread safe.
3166 Moved test server to 'ztest' directory - generic server code still
3167 in 'server' directory.
3169 Made prefix query (pquery.c) utility thread safe.
3171 Added new function modifier YAZ_EXPORT to 'export' public DLL
3172 functions when using windows (see include/yconfig.h).
3174 Added definitions to the OID database (util/oid.c) (RVDM).
3176 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
3178 Added call to ccl_rpn_delete in client program.
3180 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
3181 release of RPN structure.
3183 Added support for C++, headers uses extern "C" for public definitions.
3184 With input from RVDM.
3186 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
3187 Thanks to Ronald van der Meer (RVDM).
3189 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
3191 Added support for private extensions to the OID database
3192 (oid_setprivateoids()). Thanks to RVDM.
3194 Added optional, physical ANY (key replication)
3196 Fixed null-reference problem in GRS-1 output filter.
3198 Proximity operator added to Prefix Query Format (PQF).
3200 In test client command "base" accepts multiple databases.
3202 Fixed bug in cs_close stack that caused trouble with WINSOCK.
3206 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3208 Smallish bug-fixes in the new encoders/decoders (explain).
3210 Bug fixed in DeleteRequest.
3212 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
3214 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
3216 Added SOIF syntax (using private OID for now) to retrieval module and client.
3218 Added Update extended service.
3220 Added SearchResult-1 additional info structure.
3222 Added optional CCL (ISO8777) interpreter as separate module. Available
3225 --- 1.2 1996/6/10 (1st anniversary release)
3227 Added Summary record syntax. Lightly tested.
3229 Added OPAC record syntax. Untested.
3231 Added ResourceReport service encoders/decoders. Untested.
3233 Fixed bug in z_Unit - wrong tagging on unitSystem.
3235 Fixed bug in the DiagRecs decoder.
3237 Added options for max PDU size and session timeout to frontend-server.
3239 Added documentation of query-language parsers and other supporting utilities.
3241 [frontend-server] Added Attribute set to the bend_scanrequest API.
3243 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
3244 surrogate diagnostics were generated.
3246 [retrieval] Allow multiple local values for attribute.
3248 [retrieval] Allow multiple attributes per element in .abs files. index type.
3250 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
3252 --- 1.1pl2 1996/4/10
3254 Minor changes, mostly specific to Zebra's requirements (retrieval)
3258 Repaired bug in frontend server when running multiple listening
3259 endpoints in dynamic mode.
3261 z_External() now won't break if a known, ASN.1 value comes encapsulated
3262 in an octet-string. The value will pass through unmodified in an Odr_oct.
3264 Added a bit of code to the demo client to decode & display
3265 ASN.1-structured records represented in the octet-aligned branch of
3266 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
3268 Added z_ext_getentbyref() to the ASN module. Doc updated.
3270 * Completed the SCAN definition in the ASN module. This may break SCAN
3271 code based on older YAZ-versions at compile-time. The fix is easy -
3274 * Added 'displayTerm' and OtherInformation to the TermInfo structure
3275 under the SCAN definition. Remember to initialize this, server-people.
3277 Comstack should now support the WAIS protocol in TCP/IP mode. Note
3278 that this does not extend to ODR and ASN.
3280 Comstack allows insertion of established socket (primarily for
3281 inetd-operation of servers). Doc updated.
3283 Front-end server can now start from the inetd in TCP mode. Doc
3286 --- 1.0pl4 1996/1/24
3290 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
3291 the rank and record number.
3293 Adjustments to the frontend server.
3295 Fixed diagnostic BER dumper. It ignored the file argument.
3299 Various changes to retrieval module.
3301 Changed the union discriminators of the protocol files from enums to
3302 ints paired with #defines.
3304 *Changed oident.class to oident.oclass to avoid a reserved word in C++
3307 *Changed operator in the RPN structure to 'roperator', again to avoid a
3310 Fixed problems in Explain decoders/encoders.
3312 --- 1.0pl2 1995/12/6
3314 Memory bug in log module fixed.
3316 --- 1.0pl1 1995/12/5
3318 Occasional malloc() of 0 bytes fixed in d1_espec.c.
3320 Bug in Explain DatabaseInfo module fixed.
3322 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
3326 The shift to v1.0 signals that we now consider the *core* functionality
3327 of YAZ reasonably stable (the core being more or less equivalent to
3328 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
3329 tested (Explain not at all - though that will happen soonish).
3331 Minor changes to code to support Windows port.
3333 Various minor changes after we're getting to use GRS-1 & co. more.
3335 Added Espec-1 format.
3337 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
3338 of the protocol and it cannot be selected when encoding (maps into 'string'
3339 when decoding). Needed to talk to some servers.
3341 Demo client can request simple element set names.
3343 Added Diagnostic Format encoders/decoders.
3345 Added simple Close handling to frontend server (no hooks for resource
3346 reporting yet), and demonstration client.
3348 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
3350 --- 1.0b3 1995/08/24
3352 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
3353 handled incorrectly when records were requested in the searchResponse. This
3354 will only affect you if you use the frontend-server.
3356 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
3357 Test-client will ask for and print GRS1. Ztest will return dummy records
3360 Added Explain encoders/decoders to the service-level API. Untested.
3362 Added Extended Services: Item Order encoders and decoders to the Service-
3363 level API. Untested. We could use a recent copy of the pertinent bits
3364 of the ILL protocol to add those bits.
3366 Added diagnostic format 1 encoders/decoders to the service-level API.
3369 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
3370 odr_cons.c, which causes a more correct output.
3372 Fixed handling of searchRequest in frontend server. NextResultSetPosition
3373 was always set to 0 when no records were requested in the searchRequest.
3375 * Added better external-handling. This shouldn't harm old code that
3376 *encodes* externals. It can break code that looks for a
3377 'single-ASN1-type' representation, since those types that are known
3378 are now decoded immediately. Look at the SUTRS sample code in
3379 seshigh.c and client.c. Documentation updated.
3381 Handling of structured records in bend_fetchresponse. Length -1 marks
3382 structured record, type is deduced from format field.
3384 --- 1.0b2 1995/06/27
3385 Fairly quick maintenance release to add SUTRS support.
3387 Fixed handling of SUTRS records in the demonstration client.
3389 * Added format field to the bend_fetchrequest and bend_fetchresponce
3390 structures of the backend API (frontend server). When the record is
3391 returned, the value of the format field is mapped to an OID. The
3392 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
3393 of the record. The special value VAL_NONE in the bend_request means
3394 that no specific format was requested by the client. Documentation
3395 updated accordingly. Test server (ztest) will return a fixed dummy
3396 SUTRS record if your client requests SUTRS.
3398 Documentation updated accordingly.
3400 You can now set external libraries and RANLIB support in the top-level
3404 First public release.
