3 Limitmap ccl: deal with quotes and backslash PAZ-999
5 Handle date range from a limit parameter PAZ-997
6 The CCL term is not quoted unless it includes blanks. This will ensure
7 that r=r is handled correctly. This changes behavior a bit. If term
8 should not be converted to @and, then instead of r=r one should use

28 No longer a limit on facets.
30 Pazpar2-js no longer requires Apache2 PAZ-989
31 Package pazpar2-apache2 sets up everything WRT apache and only
32 package which requires it. pazpar2-apache depends on pazpar2-js.
36 Larger string buffer for forward address PAZ-987
37 Fixes buffer overflow that could occur if forward address is IPV6.
39 Updates to Windows NMAKE makefile for Visual Studio 2013.
43 Use YAZ backtrace facility PAZ-983. In case of crashes YAZ log may
44 include more details about the fault. Better install gdb and the
45 debug version of pazpar2 (pazpar2-dbg on Debian/Ubuntu).
47 Per target timeout PAZ-981
48 New setting pz:timeout which overrides z3950_operation timeout
53 Re-introduce journal-subpart PAZ-980
54 Both citation and journal-subpart have same value.
58 Add Ubuntu utopic 14.04 and Ubuntu saucy 13.10 to the list of packages
61 Remove from js/pz2.js the code that translates just two diagnostic
62 codes (1 and 2) into human-readable messages. This is no longer
63 necessary at all, as PazPar2 has been returning the message as well as
64 the code in its responses since December 2012. Fixes PAZ-978.
66 primo xsl produces citation rather than journal-subpart PAZ-972
67 (fix in 1.8.1 was incorrect)

93 Dump main configuration file during start of Pazpar2 PAZ-957
97 Log ingest failures and record failures:
99 Clean up logging PAZ-942
100 Use session lead in more places. Log hits/records/filtered for each
101 target when fetching is complete. Log hit count when a search
102 (response) is received. Remove some less useful log messages.
104 Fix warning about about missing (internal) stylesheet PAZ-956
106 Report number of filtered records in bytarget PAZ-954
108 Cache XML documents as they appear after normalization. The key
109 for the cache is database+record offset. Cache is removed if query
110 is modified for search. This speeds up re-establishing a result set
111 for databases where new query is same previous query.
115 poll: add assert for number of FDs; abort on poll failure

175 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
176 It's been like that since version 1.1.1 from August 2009.
178 Add support for result-set caching via memcached. See description of
179 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
181 Add support for a <metadata> container tag. Patfh from Sven Porst.
183 Add support for XInclude in main configuarion file. Patch from Sven Porst.
185 Add client_{lock,unlock} before call to non_block_events in
186 connection_continue. Problem is that if non_block_events fire records,
187 then we will not unlock client at all. And as a result, a dead-lock

235 Strip #-suffix for ZOOM URLs. PAZ-892
237 --- 1.6.34 2013/08/30
239 Fix issue with hanging show/bytarget. Could happen if new search was
240 fired with filter before show from previous show completed.
242 Add 'date' handling for solr-pz2.xsl.
244 --- 1.6.33 2013/08/13
246 pz:authentication may carry user group password. If pz:authentication
247 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
248 authentication. Two forms are allowed
251 If no blanks are present, open authentication is in use (as before).
253 Fix {prev,next}recid elements that are returned by record
254 command. These were incorrect in versions 1.6.23 thru 1.6.32.
256 --- 1.6.32 2013/06/14
258 Experimental support for snippets. If argument snippets=1 is given
259 for command record or show, the text will include <match>-tags for
260 those area that matches.
262 Fix memory leak WRT client structures (incorrect inc ref count).
264 Log when a HTTP response is serialized and the time elapsed.
266 New command, service, which returns current service XML in use for
269 --- 1.6.31 2013/05/24
271 Local limit for fields of type "generic" (ie text fields) are
272 now normalized by mergekey rule before comparison takes place.
273 Before, no normalization took place and comparsion was, thus, exact.
275 New facility: dynamic rank , which allows ranking to be changed
276 for an existing result set. The rank can be set for search or
277 show. This overrides the rank for metadata elements (which fields
280 New facility:dynamic mergekey , which allows mergekey to be changed
281 for an existing result set. The mergekey can be set for search or
284 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
285 Also, allow ports to be given as names (not just integers).
286 Fix @-notation on systems that don't support IPV6 sockets.
288 --- 1.6.30 2013/04/26
290 Add MasterKey Connect configuration. Refer to section "non-standard
291 databases" for more information.
293 Allow timeformat for log to be specified with option -m (as Metaproxy
296 New Debian package pazpar2-dbg.
298 Fix NULL ptr reference of se->relevance. If a new search is initiated
299 and a CCL query fails to parse, Pazpar2 could crash.
301 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
302 existed in 1.6.29 only.
304 --- 1.6.29 2013/04/05
306 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
307 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
308 changed by setting "host" attribute for the "listen" element.
310 Change semantics of pz:extendrecs. Allow for repeated fetches .
311 pz:extendrecs is now the number of extra records to fetch (was total
314 --- 1.6.28 2013/03/21
316 Fix hang or memory violation if show occurred before a search. (not that
317 it makes much sense to perform a show before a search).
319 --- 1.6.27 2013/03/08
321 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
324 --- 1.6.26 2013/03/08
326 New pz:metadata attribute, empty="empty-value" for Pazpar2's
327 internal representation. With this attribute, Pazpar2 treates an empty
328 pz:metadata type as having the value for "empty" - if empty.
330 New setting, pz:extendrecs, which triggers extended fetch of records
331 for a database beyond pz:maxrecs for a show command.
333 Fix warning that was falsely issued for "missing limitmap".
335 Log message for Pazpart start/stop changed. Now using same style as
336 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
338 --- 1.6.25 2013/02/07
340 Fix hang of 2nd command=show with esn/syntax given.
342 --- 1.6.24 2013/01/18
344 New merge attribute type: 'first', which takes all metadata fields
345 from first target that returns the particular field.
347 --- 1.6.23 2013/01/02
349 Extend info command with hostname and YAZ SHA1
350 Indent results for both command stat and info.
352 Allow limit on merged content. The new configuration metadata
353 element, limitcluster, configures that a metadata element (name) be used
354 as limit name for search. Applies to the whole service (ie all targets),
355 unlike pz:limitmap which is configured per-target (database).
357 New feature: limitmap local:* matches against all metadata fields.
359 Allow repeated list in limitmap spec . Separated by comma. For
360 example: value="local:title,rpn:@attr 1=4".
362 New element <message> in bytarget response. Holds diagnostic message
363 of code (say 'Unsupported Use Attribute' for Bib-1 114).
365 Improved logging for record ingestion failures.
367 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
368 when YAZ is compiled without ICU support.
370 --- 1.6.22 2012/10/11
372 Requires YAZ-4.2.40 to support native solr support.
374 Fix and improve logic handling whether or not to re-do search on sort
375 order changes. A sort order with change in ascending/descending only
376 whould not trigger a new search, which is required for targets with
377 native sorting capabilities. Each client is now checked if instructions
378 (sortmap) exist for native sorting and only client that does requires
379 it is researched. Other clients is just re-ingesting the records,
380 they already have. The resultset is now cleared if any researching
383 Connection sharing between session has broken since version 1.6.8 with
384 introduction of logic that would minimize searching if pazpar2 could
385 detect this based on same query and limits and partly sort order.
386 This could lead to segementations violations.
388 Added a chapter in the manaul about relevance ranking.
390 --- 1.6.21 2012/09/24
392 Rank tweak: follow=number will increase mult by number if two terms
393 occur next to each other; number-1 if they are one term apart , .. 0
394 if they are number a part (all in order). Default is 0 (following
395 terms has no effect).
397 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
398 value given by lead and l is length from beginning of field where
399 term occurs (l=0 for first term, l=1 for second term, ..). Default
402 Rank tweak: length=strategy. length="linear" if mult is to be divided
403 by length (existing, default behavior), length="log" if mult is to be
404 divided by log2(1+length), length="none" if mult is not to be affected
407 --- 1.6.20 2012/09/21
409 Rank algorithm details may be printed as part of show response in
410 element <relevance_info>.. This is only printed if <rank debug="yes"/>
413 Record as returned by show/record command have a minimal indentation
414 which makes things human-readable.
416 New configuration of default sorting criteria (sort-default) in
417 service definition. If no criteria is defined it will be as before
420 Search command now supports sort parameter just as the show command.
421 If no parameter is give, it will use the service sort-default value.
423 --- 1.6.19 2012/09/18
425 Rank algorithm skips strings that gets normalized to empty string.
426 For example, & and ! could map to the empty string. The weight for
427 those terms is now 0 (as if they were not part of the query).
429 Rank algorithm does not use CCL from limitmap; only from the query
430 parameter (user query).
434 --- 1.6.18 2012/09/17
436 Rank algorithm configurable by 'rank' element inside service. So far
437 only, attribute 'cluster' is recognized. If cluster="yes", multiple
438 records inside a cluster boosts higher than single records. This
439 is default behavior and existing behavior. cluster="no" takes the
440 average score of each record in a cluster.
442 --- 1.6.17 2012/09/05
444 Fix bad re-use of connections (connections with changing proxy should not
447 --- 1.6.16 2012/08/22
449 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
450 resultset and sorting when the sort order is position. However this will be done on
451 every client poll, which will make pazpar2 continuing reset and fetching.
452 It should only be done on FIRST request where the sort order change.
454 Fix an issue on suggestion option: Also disable suggestions on empty string.
456 Clean up in turbo marc stylesheet.
458 Remove the hardcoded size of termlists.
460 --- 1.6.15 2012/06/27
462 New facility: ccldirective may be given in service definition. Allows
463 CCL parsing to be customized a bit, such as defining names of operators
466 New facility: raw record by checksum, rather than offset. The record
467 command optionally takes checksum which identifies certain record from
470 New facility: per field ranking. Rank may be given as M [F N] where
471 M is default rank and N is rank for CCL terms from field F.
473 --- 1.6.14 2012/06/04
475 Fix for IE7/8 in pz.js
477 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
479 Lower log level some places.
481 Remove some invalid test results.
483 --- 1.6.13 2012/05/23
485 Introducing a version=2 parameter for show, termlist and bytarget commands.
486 This enables pazpar2 to return approximation on hit and count count when
487 doing record filtering using the limit parameter on search and a
488 limitmap with a value of "local:"
490 Setting pz:xslt may embed local XSLT as an alternative to referring
492 Value is not CDATA but XML nodes embedded, so escaping is not necessary
493 but a root element *must* be present. For example:
494 <settings target="target="z3950.indexdata.com/marc">
503 Metadata field rank may given by XML internal document (pz:xslt
504 result). If rank is not given, the rank from service description is
507 Metadata field can now configured a default limitmap and facetmap.
508 Setting limitmap to "local:" would work for all kind of targets, but would
509 prob. not be the optimal solution. But at least better than the default behavior
510 of pazpar2 where no filtering is done.
512 A service definition can now also contains <set/> that defines service-wide
513 settings. These will override server-wide sets and will be overridded by
516 New setting, pz:present_chunk, that specifies number of records to fetch
517 at a time. Zero will disable chunkation; will fetch max_records at once.
519 --- 1.6.12 2012/03/14
521 Revert the format change in termlist response, that could break
522 some clients / UIs since they were expecting an (empty) element
523 if no facet values was found.
525 --- 1.6.11 2012/03/07
527 Revert the behavior of returning errors when unable to block
528 on termlist, bytarget and search, when unable to block due to
529 other block. The client will now receive a regular response,
530 but it will be logged in the server. A parameter (report) is
531 added to change behavior to return error response or WARNING
532 status message. Consider this "API" as private, as it is mostly
533 untested and could be changed in future releases.
535 Fix spell error in pz2.js fix in 1.6.10.
537 New Marc2TurboMarc.xsl (contribution from Sven Porst).
538 Can solve the missing marc21.xsl updates in some cases.
540 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
541 substring (contribtion from Sven Porst)
543 marc21.xsl: fix 1-based substring call
545 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
547 Add test_termlist_block to test suite
549 --- 1.6.10 2012/02/23
551 Fix SEGV for invalid PQFs and SRU/SOLR targets
552 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
554 Fix pz2.js: "null object" due to change in in bytarget result XML.
556 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
557 Added this normalization to the other subject-long fields (d6xx),
558 where it was missing.
560 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
561 Still differences around medium and holdings. marc21.xsl is not
562 longer active used by Index Data, and should be considered unsupported.
563 Use tmarc.xsl instead.
567 Fix SEGV that could occur for failed connections.
571 Fix bug for command sort that could return no results for active clients
572 (from previous search). This bug was present in 1.6.6-1.6.7.
574 Fix bug in results that could include results that should have been
575 filtered out. This bug was present in 1.6.6-1.6.7.
579 Fix bug introduced in 1.6.6 where a connection re-use could stall
582 Local filtering may now specify a local metadata field, eg.
583 pz:limitmap:somefield[t]=local:otherfield
587 For search, when limit and or filtering is in place and search
588 is identical to previous search, the result set is re-used and the
589 target is not searched.
591 Limits may work perform local filtering as well, by using "local:"
596 Updated bytarget command to contain a suggestions element with misspelled
597 words and suggestions to these. pz2.js has been updated to deliver this
598 onwards as well. Only target that currently delivers this is the solr
599 client in YAZ 4.2.18.
603 New service definition element, xslt, that allows an embedded stylesheet
604 to be defined. This can be referred to from pz:xslt as an alternative to
607 New pz:sortmap:field setting for specifying hints on how to make
608 a target natively sort on a field. This is used for command=show in
609 conjunction with sort.
611 New pz:url setting for specifying the actual URL for a target. When
612 this is used the target ID is not used as URL anymore and the target ID
613 may be almost any string (not including []).
615 command=termlist without name parameter returns all termlists/facets.
616 Previously if name parameter was omitted, only "subject" was returned.
620 Make termlist sorting stable. Terms with same frequency are now sorted by
621 their display name. This makes a pretty display and improves our
622 regression test because qsort is not a stable sort.
624 New sort parameter value 'position'. The 'position' sorts merged records
625 by their original position from the remote target. This is primarily useful
626 for debugging and may be used for targets that already perform some kind
627 of relevance ranking. Note that sort by default is decreasing; so to get
628 records in their original order sort=position:1 must be used.
632 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
634 Facility to change working directory for pazpar2 daemon. Option -wdir
635 sets working directory to dir. This facility is useful if core dumps
636 must be saved. In this case, the current working directory must be
637 writable by the running user, such as "nobody".
641 New configuration element <icu_chain> for <server>/<service> which
642 allows a named ICU rule (chain) to be defined. The names relevance,
643 sort, mergekey and facet are used for those operations. The definition
644 <icu_chain id="sort" locale="en"> .. </icu_chain>
646 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
647 And so on.. for relevance, mergekey and facet as well. The latter
648 style is deprecated. The facet terms are normalized by the facet
649 rule by default. This may be changed on a metadata field basis by
650 defining the new attribute 'facetrule' for the metadata element.
652 <icu_chain id="myrule" locale="en"> ... </icu_chain>
653 <metadata name="author" termlist="yes" facetrule="myrule"/>
655 Preserve rorder for merged metadata. Fixes issue as reported by Sven
656 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
658 tmarc.xsl: set journal-subpart to 773$ only.
662 Modify the behavior for the limit parameter (first defined in 1.5.7).
663 Mapping of limit searches are now defined by the new configuration item
664 pz:limitmap. Fix a dead-lock problem with the limit parameter.
666 Extend tmarc.xsl to extract 773$g data (OpenURL).
670 ICU default maps remove backquote (`).
672 Command 'search' takes limit parameter (optional). The limit parameter
673 allows a search to be limited one or more facets and the corresponding
674 values. This is for server side filtering.
676 Configure tweak: Use -lm for log(3) if needed
680 Fix a problem with skiparticle sortkey that could be completely
681 ignored (and reduced to "").
683 Fix dependency problem in pazpar2 RPM package (did not require
684 libyaz4 as it should).
688 Fix memory leak that occurred for command=termlist&name=xtargets .
690 Pazpar2 may save HTTP requests. Enabled by option -R.
694 Experimental support for DTIC DADS target. New dads-pz2.xsl.
696 Support for query_syntax (overrides the default for SRU | Z39.50)
698 Support for extraArgs (ZOOM "extraArgs" option) for targets
700 New commands: status-server and status-session
704 Fix for threaded runs: Client now have a copy of the database URL,
705 which can used after the database has been release from the client.
706 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
708 tmarc.xsl: Add journal-title-abbrev and full text.
710 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
712 Fix for cmd=record before search.
714 Session Logging clean up.
716 Fix wrong termlist factor when maxrecs is different from 100.
720 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
721 Term factor is default enabled but can be diseabled by
722 pz:termlist_term_factor=0
726 Add scaling of facet count. Currently always enabled, needs fixing.
727 Allow user-defined info for target suffix. This has no meaning in
728 Pazpar2 except to distinguish targets from each other. The suffix
729 data begins with #. For example z3950.indexdata.com/gils#Mydata
731 Added exact-match recordfilter; format name=value
735 SOLR support. Pazpar2 may operate as web service client for SOLR.
739 Fix for show command and block=1 (dead lock). Bug was introduced in
744 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
745 tested on CentOS 5.5 only.
749 Fix problem with result sets being removed from a client session
750 if the connection for it was resused by another session. Bug #3489.
752 New iphone UI for Pazpar2 (www/iphone).
756 Fixes for threaded operation.
758 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
760 New example services in etc/services in source. In the Debian packages
761 these are located in /etc/pazpar2/services-available
763 Threaded mode operational on Windows. Requires Windows 7 or Windows
766 Default value of setting pz:max_connections is 0 which means that there
767 is no limit on number of connections.
771 Pazpar2 may operate in threaded mode. Enabled by element threads in
772 the configuration. See pazpar2_conf for details.
774 New setting setting: pz:max_connections. Setting pz:max_connections is
775 a limit of number of sockets to a host. When this limit is reached,
776 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
777 The client will be marked Client_Error when it can not be searched
778 (other clients in a session may work). If pz:max_connections is not set
779 for a target, a value of 30 will be used. Note: the pz:max_connections
780 will only work in threaded mode.
782 pz2.js: JSON support for show.
784 Debian package: Enable default service, default.xml, before starting
785 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
789 Debian version depends on on libyaz4. Note that Pazpar2 will still
790 compile from source with YAZ 3.
792 Split services into separate files. The example configuration file
793 pazpar2.cfg.dist now includes a default service default.xml (part of
794 etc). And default.xml includes settings/edu.xml. The default.xml file,
795 not to be confused with settings/defaults.xml, is a template for jsdemo
796 and other services. The Debian package installs /etc/pazpar2/server.xml
797 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
798 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
799 The default.xml (from etc) is installed in /etc/pazpar2/services-available
800 and a symlink to it is created from services-enabled. The default.xml
801 service is unnamed and, thus, will be used by jsdemo and test1.
803 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
804 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
808 Support for additional fields in cf.xsl and pazpar2.conf.dist:
809 publisher, available, due, location (=locallocation), callno
810 (=callnumber), thumburl and score.
812 Describe pz:xslt and the auto setting.
814 Move mergekey definition away from the normalization stylesheets and
815 define a mergekey common for all target types in pazpar2.cfg.
817 Code update: Use the Odr_int type for hit counts. This is part of
818 YAZ 3.0.47 and later and so configure checks for that.
822 Metadata attribute 'skiparticle' also works for ICU based
823 normalization. (was only working for the non-ICU/ASCII before).
825 Command bytarget with argument settings=1 will show settings per
826 target.. This is to be able to verify correct settings and be able to
827 test that they are correct. The database settings array size is now
828 also stored.. Problems with database settings array is that if not
829 careful it will be too small (smaller than dictionary per-service
832 Make record list sorting stable by comparing mergekey for records if
833 relevance/title or other sorting criteria all match. This is merely to
834 ensure that our regressions tests works (reproducible output).
836 Relevance calculation changes: use a different denominator (length) for
837 per-field relevance scoring.. Instead of length of all ranked fields we
838 now use length of individual fields (as if they were individual "free"
839 text fields). This will ensure that documents with a long field with no
840 match (say description) will not "hurt" a title match.
842 Diagnostic member was not set on connection error. Fixed
846 Command search takes two optional parameters, startecs and maxrecs,
847 that specifies the start offset (0, 1, ...) and maximum number of records
848 to fetch for each target.
850 XSLTs + MARC maps are cached within a session so we don't re-parse
851 them over and over again. Even for a session with a single search
852 there's much to be gained because many targets use the same
855 The metadata attribute 'mergekey' now takes one of three values 'no',
856 'required', 'optional' . And the resulting mergekey from metadata
857 is now ordered in the same way as metadata in the service definition.
858 Older Pazpar2 version use the order in which metadata appeared in a
861 The search argument 'filter' now offers a new operator ~ which does a
862 substring match. The = operator works as before: string match for
863 anything but pz:id, or target match for pz:id.
865 New setting pz:recordfilter. The value of this setting takes the
866 form name[~value]. This setting makes Pazpar2 ignore all retrieved
867 records that do not have the metadata element name with value substring
870 Pazpar2 allows YAZ log level to be set (option -v).
874 For WS responses Pazpar2 creates XML header. Exception: raw record.
876 Setting XML files are now stored in etc/settings instead of etc. This
877 reflects the layout with the Debian package layout.
879 Settings may be posted for command=settings. The POSTed settings must
880 have root element 'settings' like regular setting files. In order to be
881 recognized, the POST request must use Content-Type=text/xml.
883 A service may be posted for command=init. This service will be used
884 during the session. The service may have its own target settings,
885 ICU config, timeout, etc. In order to be recognized, the POST request
886 must use Content-Type=text/xml.
888 Timeout values may be given per-service. That's element 'timeout'
889 which takes three attribute values (a subset may be given): 'session',
890 'z3950_operation', 'z3950_session'. Option -T is no longer supported
891 - used to specify session timeout.
893 Option -t tests the Pazpar2 configuration and returns exit code
894 (0=success, non-zero=failure). In previous version of Pazpar2, -t
895 specified local settings.
897 In version 1.2.0 the configuration file - after include processing -
898 was dumped to stdout. Now, the configuration is only dumped to the
899 yaz log file if option -d is given.
903 Configuration may now have multiple server areas. This means that a
904 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
905 yet supported - on a server basis. Configuration may also have multiple
906 services .. That is repeating service elements inside a server. Each
907 has an attribute 'id' which serves as service ID. This ID in turn may
908 be used in a Pazpar2 session, by specifying parameter service=ID for
909 command init. There can be at most one unnamed service inside a server
910 which can be referred to by not specifying an service ID for command
911 init (backwards compatible). In order to partition multiple servers and
912 services a new include directive has been added. This takes an attribute
913 'src' which specifies one or more sub-files. For example to include
914 service files, one might use:
915 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
916 It is the intention that that completely makes the settings directive
919 Fix problem where the record command would wait forever if there were
920 no targets to wait for (activeclients == 0).
924 One result set is created per session (last search) rather than for
925 each connection which happen to be shared (bug #3009).
927 marc21 stylesheets changed for efficiency.
931 Session timeout may be specified on the command-line as option -T.
933 Pazpar2 may now be operated in a no-merged mode for records.. All records
934 will be considered unique. This mode is enabled if no mergekey is
935 generated by the normalization stylesheet (pz:xslt).
937 Pazpar2 caches original records from each target and the 'record' command
938 with offset returns the original record if 'syntax' and 'esn' are NOT
939 specified. This speeds up retrieval of original records but also means
940 that Pazpar2 uses more memory. The cached records will be freed when the
941 session terminates or a new search is executed.
943 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
944 library part of YAZ is used.
946 Added SRU client support.
948 Automatically computes pz:nativesyntax if not provided. Works for XML and
951 --- 1.0.13 2008/11/24
953 Command bytarget returns name of target (if defined).
955 --- 1.0.12 2008/11/04
957 Fixed bug #2021.. location now holds all brief elements.
959 --- 1.0.11 2008/10/15
961 Fixed check for application/x-www-form-urlencoded parameters.
963 --- 1.0.10 2008/10/14

967 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
971 Changed the JS library pz2.js to use POST for long URL (+ params).
973 Added installation instructions for Windows. Note: NT services is
974 NOT available until we make a new release of YAZ.
976 Preserve order of repeated metadata fields (they were reversed before).
978 More MARC21 information extracted for metadata.
982 Fixed bug #1162: HTML entities are not escaped properly.
984 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
988 Marc21 stylesheet updated to reflect multiple full text fields
992 Fixed bug in pz2.js WRT DOMElement attributes on IE.
994 Fixed bug 2100: Database wildcards not working
998 Added support for retrieval of records in binary.
1000 Fixed bug 1794: Pazpar2 does not return valid XML.
1002 Deal with ICU not returning sortkey (resulted in SEGV before).
1004 --- 1.0.4 2007/09/28
1006 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
1007 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
1009 Improved diagnostics when Pazpar2 HTTP decoding fails.
1011 Pazpar2 requests may be POSTed as using Content-Type
1012 application/x-www-form-urlencoded.
1014 Pazpar2 honors LF in HTTP headers.
1016 Handle targets that handle negative hit counts (should not happen, but it
1019 --- 1.0.3 2007/09/19
1021 ICU is used for tokenization and normalization of the following: mergekey,
1022 sorting, relevance terms.
1024 Debian package now enables ICU tokenization and normalization by default.
1026 --- 1.0.2 2007/08/22
1028 Exposed user setting values (i.e. non-pz: names) to the record systems in two
1029 ways: Either as parameters to the normalization stylesheets (which would allow the
1030 programmer to postprocess or use the values in any way) or after the normalization
1031 step, in which case values are made part of the normalized record (and available for
1032 sorting, termlists, display, or other interface-related use.
1034 Implemented sorting by year.
1036 Option -d dumps records to the current log file instead of stderr.
1038 Fixes for compilation on cygwin.
1040 Z39.50 client code uses pz:elements. pz:elements was recognized in
1041 earlier Pazpar2 versions but it was not used for anything.
1043 icu_chain_test is using fgets instead of getline - fixes compilation
1046 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
1047 query conversions fail (rather than _any_). This means targets that do
1048 not support some fields are ignored in a search.
1050 --- 1.0.1 2007/07/03
1052 Improved handling of socket timeout for Z39.50 connections.
1054 Misc documentation updates and spell fixes.
1056 Debian package pazpar2 creates log rotate entry.
1058 Debian package pazpar2-apache2 reloads Apache2.
1060 jsdemo included in distribution. It illustrates the use of the js/pz2.js
1063 --- 1.0.0 2007/06/20
