17 Log ingest failures and record failures:
19 Clean up logging PAZ-942
20 Use session lead in more places. Log hits/records/filtered for each
21 target when fetching is complete. Log hit count when a search

24 Fix warning about about missing (internal) stylesheet PAZ-956
26 Report number of filtered records in bytarget PAZ-954
28 Cache XML documents as they appear after normalization. The key
29 for the cache is database+record offset. Cache is removed if query
30 is modified for search. This speeds up re-establishing a result set
31 for databases where new query is same previous query.

87 this code is only executed once.
89 Fix typos is sortmap documentation.
91 Doc: fix misplaced variablelist tag.
95 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
96 It's been like that since version 1.1.1 from August 2009.
98 Add support for result-set caching via memcached. See description of
99 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
101 Add support for a <metadata> container tag. Patfh from Sven Porst.
103 Add support for XInclude in main configuarion file. Patch from Sven Porst.
105 Add client_{lock,unlock} before call to non_block_events in
106 connection_continue. Problem is that if non_block_events fire records,
107 then we will not unlock client at all. And as a result, a dead-lock

159 Fix issue with hanging show/bytarget. Could happen if new search was
160 fired with filter before show from previous show completed.
162 Add 'date' handling for solr-pz2.xsl.
164 --- 1.6.33 2013/08/13
166 pz:authentication may carry user group password. If pz:authentication
167 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
168 authentication. Two forms are allowed
171 If no blanks are present, open authentication is in use (as before).
173 Fix {prev,next}recid elements that are returned by record
174 command. These were incorrect in versions 1.6.23 thru 1.6.32.
176 --- 1.6.32 2013/06/14
178 Experimental support for snippets. If argument snippets=1 is given
179 for command record or show, the text will include <match>-tags for
180 those area that matches.
182 Fix memory leak WRT client structures (incorrect inc ref count).
184 Log when a HTTP response is serialized and the time elapsed.
186 New command, service, which returns current service XML in use for
189 --- 1.6.31 2013/05/24
191 Local limit for fields of type "generic" (ie text fields) are
192 now normalized by mergekey rule before comparison takes place.
193 Before, no normalization took place and comparsion was, thus, exact.
195 New facility: dynamic rank , which allows ranking to be changed
196 for an existing result set. The rank can be set for search or
197 show. This overrides the rank for metadata elements (which fields
200 New facility:dynamic mergekey , which allows mergekey to be changed
201 for an existing result set. The mergekey can be set for search or
204 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
205 Also, allow ports to be given as names (not just integers).
206 Fix @-notation on systems that don't support IPV6 sockets.
208 --- 1.6.30 2013/04/26
210 Add MasterKey Connect configuration. Refer to section "non-standard
211 databases" for more information.
213 Allow timeformat for log to be specified with option -m (as Metaproxy
216 New Debian package pazpar2-dbg.
218 Fix NULL ptr reference of se->relevance. If a new search is initiated
219 and a CCL query fails to parse, Pazpar2 could crash.
221 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
222 existed in 1.6.29 only.
224 --- 1.6.29 2013/04/05
226 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
227 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
228 changed by setting "host" attribute for the "listen" element.
230 Change semantics of pz:extendrecs. Allow for repeated fetches .
231 pz:extendrecs is now the number of extra records to fetch (was total
234 --- 1.6.28 2013/03/21
236 Fix hang or memory violation if show occurred before a search. (not that
237 it makes much sense to perform a show before a search).
239 --- 1.6.27 2013/03/08
241 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
244 --- 1.6.26 2013/03/08
246 New pz:metadata attribute, empty="empty-value" for Pazpar2's
247 internal representation. With this attribute, Pazpar2 treates an empty
248 pz:metadata type as having the value for "empty" - if empty.
250 New setting, pz:extendrecs, which triggers extended fetch of records
251 for a database beyond pz:maxrecs for a show command.
253 Fix warning that was falsely issued for "missing limitmap".
255 Log message for Pazpart start/stop changed. Now using same style as
256 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
258 --- 1.6.25 2013/02/07
260 Fix hang of 2nd command=show with esn/syntax given.
262 --- 1.6.24 2013/01/18
264 New merge attribute type: 'first', which takes all metadata fields
265 from first target that returns the particular field.
267 --- 1.6.23 2013/01/02
269 Extend info command with hostname and YAZ SHA1
270 Indent results for both command stat and info.
272 Allow limit on merged content. The new configuration metadata
273 element, limitcluster, configures that a metadata element (name) be used
274 as limit name for search. Applies to the whole service (ie all targets),
275 unlike pz:limitmap which is configured per-target (database).
277 New feature: limitmap local:* matches against all metadata fields.
279 Allow repeated list in limitmap spec . Separated by comma. For
280 example: value="local:title,rpn:@attr 1=4".
282 New element <message> in bytarget response. Holds diagnostic message
283 of code (say 'Unsupported Use Attribute' for Bib-1 114).
285 Improved logging for record ingestion failures.
287 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
288 when YAZ is compiled without ICU support.
290 --- 1.6.22 2012/10/11
292 Requires YAZ-4.2.40 to support native solr support.
294 Fix and improve logic handling whether or not to re-do search on sort
295 order changes. A sort order with change in ascending/descending only
296 whould not trigger a new search, which is required for targets with
297 native sorting capabilities. Each client is now checked if instructions
298 (sortmap) exist for native sorting and only client that does requires
299 it is researched. Other clients is just re-ingesting the records,
300 they already have. The resultset is now cleared if any researching
303 Connection sharing between session has broken since version 1.6.8 with
304 introduction of logic that would minimize searching if pazpar2 could
305 detect this based on same query and limits and partly sort order.
306 This could lead to segementations violations.
308 Added a chapter in the manaul about relevance ranking.
310 --- 1.6.21 2012/09/24
312 Rank tweak: follow=number will increase mult by number if two terms
313 occur next to each other; number-1 if they are one term apart , .. 0
314 if they are number a part (all in order). Default is 0 (following
315 terms has no effect).
317 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
318 value given by lead and l is length from beginning of field where
319 term occurs (l=0 for first term, l=1 for second term, ..). Default
322 Rank tweak: length=strategy. length="linear" if mult is to be divided
323 by length (existing, default behavior), length="log" if mult is to be
324 divided by log2(1+length), length="none" if mult is not to be affected
327 --- 1.6.20 2012/09/21
329 Rank algorithm details may be printed as part of show response in
330 element <relevance_info>.. This is only printed if <rank debug="yes"/>
333 Record as returned by show/record command have a minimal indentation
334 which makes things human-readable.
336 New configuration of default sorting criteria (sort-default) in
337 service definition. If no criteria is defined it will be as before
340 Search command now supports sort parameter just as the show command.
341 If no parameter is give, it will use the service sort-default value.
343 --- 1.6.19 2012/09/18
345 Rank algorithm skips strings that gets normalized to empty string.
346 For example, & and ! could map to the empty string. The weight for
347 those terms is now 0 (as if they were not part of the query).
349 Rank algorithm does not use CCL from limitmap; only from the query
350 parameter (user query).
354 --- 1.6.18 2012/09/17
356 Rank algorithm configurable by 'rank' element inside service. So far
357 only, attribute 'cluster' is recognized. If cluster="yes", multiple
358 records inside a cluster boosts higher than single records. This
359 is default behavior and existing behavior. cluster="no" takes the
360 average score of each record in a cluster.
362 --- 1.6.17 2012/09/05
364 Fix bad re-use of connections (connections with changing proxy should not
367 --- 1.6.16 2012/08/22
369 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
370 resultset and sorting when the sort order is position. However this will be done on
371 every client poll, which will make pazpar2 continuing reset and fetching.
372 It should only be done on FIRST request where the sort order change.
374 Fix an issue on suggestion option: Also disable suggestions on empty string.
376 Clean up in turbo marc stylesheet.
378 Remove the hardcoded size of termlists.
380 --- 1.6.15 2012/06/27
382 New facility: ccldirective may be given in service definition. Allows
383 CCL parsing to be customized a bit, such as defining names of operators
386 New facility: raw record by checksum, rather than offset. The record
387 command optionally takes checksum which identifies certain record from
390 New facility: per field ranking. Rank may be given as M [F N] where
391 M is default rank and N is rank for CCL terms from field F.
393 --- 1.6.14 2012/06/04
395 Fix for IE7/8 in pz.js
397 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
399 Lower log level some places.
401 Remove some invalid test results.
403 --- 1.6.13 2012/05/23
405 Introducing a version=2 parameter for show, termlist and bytarget commands.
406 This enables pazpar2 to return approximation on hit and count count when
407 doing record filtering using the limit parameter on search and a
408 limitmap with a value of "local:"
410 Setting pz:xslt may embed local XSLT as an alternative to referring
412 Value is not CDATA but XML nodes embedded, so escaping is not necessary
413 but a root element *must* be present. For example:
414 <settings target="target="z3950.indexdata.com/marc">
423 Metadata field rank may given by XML internal document (pz:xslt
424 result). If rank is not given, the rank from service description is
427 Metadata field can now configured a default limitmap and facetmap.
428 Setting limitmap to "local:" would work for all kind of targets, but would
429 prob. not be the optimal solution. But at least better than the default behavior
430 of pazpar2 where no filtering is done.
432 A service definition can now also contains <set/> that defines service-wide
433 settings. These will override server-wide sets and will be overridded by
436 New setting, pz:present_chunk, that specifies number of records to fetch
437 at a time. Zero will disable chunkation; will fetch max_records at once.
439 --- 1.6.12 2012/03/14
441 Revert the format change in termlist response, that could break
442 some clients / UIs since they were expecting an (empty) element
443 if no facet values was found.
445 --- 1.6.11 2012/03/07
447 Revert the behavior of returning errors when unable to block
448 on termlist, bytarget and search, when unable to block due to
449 other block. The client will now receive a regular response,
450 but it will be logged in the server. A parameter (report) is
451 added to change behavior to return error response or WARNING
452 status message. Consider this "API" as private, as it is mostly
453 untested and could be changed in future releases.
455 Fix spell error in pz2.js fix in 1.6.10.
457 New Marc2TurboMarc.xsl (contribution from Sven Porst).
458 Can solve the missing marc21.xsl updates in some cases.
460 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
461 substring (contribtion from Sven Porst)
463 marc21.xsl: fix 1-based substring call
465 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
467 Add test_termlist_block to test suite
469 --- 1.6.10 2012/02/23
471 Fix SEGV for invalid PQFs and SRU/SOLR targets
472 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
474 Fix pz2.js: "null object" due to change in in bytarget result XML.
476 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
477 Added this normalization to the other subject-long fields (d6xx),
478 where it was missing.
480 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
481 Still differences around medium and holdings. marc21.xsl is not
482 longer active used by Index Data, and should be considered unsupported.
483 Use tmarc.xsl instead.
487 Fix SEGV that could occur for failed connections.
491 Fix bug for command sort that could return no results for active clients
492 (from previous search). This bug was present in 1.6.6-1.6.7.
494 Fix bug in results that could include results that should have been
495 filtered out. This bug was present in 1.6.6-1.6.7.
499 Fix bug introduced in 1.6.6 where a connection re-use could stall
502 Local filtering may now specify a local metadata field, eg.
503 pz:limitmap:somefield[t]=local:otherfield
507 For search, when limit and or filtering is in place and search
508 is identical to previous search, the result set is re-used and the
509 target is not searched.
511 Limits may work perform local filtering as well, by using "local:"
516 Updated bytarget command to contain a suggestions element with misspelled
517 words and suggestions to these. pz2.js has been updated to deliver this
518 onwards as well. Only target that currently delivers this is the solr
519 client in YAZ 4.2.18.
523 New service definition element, xslt, that allows an embedded stylesheet
524 to be defined. This can be referred to from pz:xslt as an alternative to
527 New pz:sortmap:field setting for specifying hints on how to make
528 a target natively sort on a field. This is used for command=show in
529 conjunction with sort.
531 New pz:url setting for specifying the actual URL for a target. When
532 this is used the target ID is not used as URL anymore and the target ID
533 may be almost any string (not including []).
535 command=termlist without name parameter returns all termlists/facets.
536 Previously if name parameter was omitted, only "subject" was returned.
540 Make termlist sorting stable. Terms with same frequency are now sorted by
541 their display name. This makes a pretty display and improves our
542 regression test because qsort is not a stable sort.
544 New sort parameter value 'position'. The 'position' sorts merged records
545 by their original position from the remote target. This is primarily useful
546 for debugging and may be used for targets that already perform some kind
547 of relevance ranking. Note that sort by default is decreasing; so to get
548 records in their original order sort=position:1 must be used.
552 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
554 Facility to change working directory for pazpar2 daemon. Option -wdir
555 sets working directory to dir. This facility is useful if core dumps
556 must be saved. In this case, the current working directory must be
557 writable by the running user, such as "nobody".
561 New configuration element <icu_chain> for <server>/<service> which
562 allows a named ICU rule (chain) to be defined. The names relevance,
563 sort, mergekey and facet are used for those operations. The definition
564 <icu_chain id="sort" locale="en"> .. </icu_chain>
566 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
567 And so on.. for relevance, mergekey and facet as well. The latter
568 style is deprecated. The facet terms are normalized by the facet
569 rule by default. This may be changed on a metadata field basis by
570 defining the new attribute 'facetrule' for the metadata element.
572 <icu_chain id="myrule" locale="en"> ... </icu_chain>
573 <metadata name="author" termlist="yes" facetrule="myrule"/>
575 Preserve rorder for merged metadata. Fixes issue as reported by Sven
576 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
578 tmarc.xsl: set journal-subpart to 773$ only.
582 Modify the behavior for the limit parameter (first defined in 1.5.7).
583 Mapping of limit searches are now defined by the new configuration item
584 pz:limitmap. Fix a dead-lock problem with the limit parameter.
586 Extend tmarc.xsl to extract 773$g data (OpenURL).
590 ICU default maps remove backquote (`).
592 Command 'search' takes limit parameter (optional). The limit parameter
593 allows a search to be limited one or more facets and the corresponding
594 values. This is for server side filtering.
596 Configure tweak: Use -lm for log(3) if needed
600 Fix a problem with skiparticle sortkey that could be completely
601 ignored (and reduced to "").
603 Fix dependency problem in pazpar2 RPM package (did not require
604 libyaz4 as it should).
608 Fix memory leak that occurred for command=termlist&name=xtargets .
610 Pazpar2 may save HTTP requests. Enabled by option -R.
614 Experimental support for DTIC DADS target. New dads-pz2.xsl.
616 Support for query_syntax (overrides the default for SRU | Z39.50)
618 Support for extraArgs (ZOOM "extraArgs" option) for targets
620 New commands: status-server and status-session
624 Fix for threaded runs: Client now have a copy of the database URL,
625 which can used after the database has been release from the client.
626 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
628 tmarc.xsl: Add journal-title-abbrev and full text.
630 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
632 Fix for cmd=record before search.
634 Session Logging clean up.
636 Fix wrong termlist factor when maxrecs is different from 100.
640 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
641 Term factor is default enabled but can be diseabled by
642 pz:termlist_term_factor=0
646 Add scaling of facet count. Currently always enabled, needs fixing.
647 Allow user-defined info for target suffix. This has no meaning in
648 Pazpar2 except to distinguish targets from each other. The suffix
649 data begins with #. For example z3950.indexdata.com/gils#Mydata
651 Added exact-match recordfilter; format name=value
655 SOLR support. Pazpar2 may operate as web service client for SOLR.
659 Fix for show command and block=1 (dead lock). Bug was introduced in
664 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
665 tested on CentOS 5.5 only.
669 Fix problem with result sets being removed from a client session
670 if the connection for it was resused by another session. Bug #3489.
672 New iphone UI for Pazpar2 (www/iphone).
676 Fixes for threaded operation.
678 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
680 New example services in etc/services in source. In the Debian packages
681 these are located in /etc/pazpar2/services-available
683 Threaded mode operational on Windows. Requires Windows 7 or Windows
686 Default value of setting pz:max_connections is 0 which means that there
687 is no limit on number of connections.
691 Pazpar2 may operate in threaded mode. Enabled by element threads in
692 the configuration. See pazpar2_conf for details.
694 New setting setting: pz:max_connections. Setting pz:max_connections is
695 a limit of number of sockets to a host. When this limit is reached,
696 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
697 The client will be marked Client_Error when it can not be searched
698 (other clients in a session may work). If pz:max_connections is not set
699 for a target, a value of 30 will be used. Note: the pz:max_connections
700 will only work in threaded mode.
702 pz2.js: JSON support for show.
704 Debian package: Enable default service, default.xml, before starting
705 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
709 Debian version depends on on libyaz4. Note that Pazpar2 will still
710 compile from source with YAZ 3.
712 Split services into separate files. The example configuration file
713 pazpar2.cfg.dist now includes a default service default.xml (part of
714 etc). And default.xml includes settings/edu.xml. The default.xml file,
715 not to be confused with settings/defaults.xml, is a template for jsdemo
716 and other services. The Debian package installs /etc/pazpar2/server.xml
717 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
718 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
719 The default.xml (from etc) is installed in /etc/pazpar2/services-available
720 and a symlink to it is created from services-enabled. The default.xml
721 service is unnamed and, thus, will be used by jsdemo and test1.
723 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
724 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
728 Support for additional fields in cf.xsl and pazpar2.conf.dist:
729 publisher, available, due, location (=locallocation), callno
730 (=callnumber), thumburl and score.
732 Describe pz:xslt and the auto setting.
734 Move mergekey definition away from the normalization stylesheets and
735 define a mergekey common for all target types in pazpar2.cfg.
737 Code update: Use the Odr_int type for hit counts. This is part of
738 YAZ 3.0.47 and later and so configure checks for that.
742 Metadata attribute 'skiparticle' also works for ICU based
743 normalization. (was only working for the non-ICU/ASCII before).
745 Command bytarget with argument settings=1 will show settings per
746 target.. This is to be able to verify correct settings and be able to
747 test that they are correct. The database settings array size is now
748 also stored.. Problems with database settings array is that if not
749 careful it will be too small (smaller than dictionary per-service
752 Make record list sorting stable by comparing mergekey for records if
753 relevance/title or other sorting criteria all match. This is merely to
754 ensure that our regressions tests works (reproducible output).
756 Relevance calculation changes: use a different denominator (length) for
757 per-field relevance scoring.. Instead of length of all ranked fields we
758 now use length of individual fields (as if they were individual "free"
759 text fields). This will ensure that documents with a long field with no
760 match (say description) will not "hurt" a title match.
762 Diagnostic member was not set on connection error. Fixed
766 Command search takes two optional parameters, startecs and maxrecs,
767 that specifies the start offset (0, 1, ...) and maximum number of records
768 to fetch for each target.
770 XSLTs + MARC maps are cached within a session so we don't re-parse
771 them over and over again. Even for a session with a single search
772 there's much to be gained because many targets use the same
775 The metadata attribute 'mergekey' now takes one of three values 'no',
776 'required', 'optional' . And the resulting mergekey from metadata
777 is now ordered in the same way as metadata in the service definition.
778 Older Pazpar2 version use the order in which metadata appeared in a
781 The search argument 'filter' now offers a new operator ~ which does a
782 substring match. The = operator works as before: string match for
783 anything but pz:id, or target match for pz:id.
785 New setting pz:recordfilter. The value of this setting takes the
786 form name[~value]. This setting makes Pazpar2 ignore all retrieved
787 records that do not have the metadata element name with value substring
790 Pazpar2 allows YAZ log level to be set (option -v).
794 For WS responses Pazpar2 creates XML header. Exception: raw record.
796 Setting XML files are now stored in etc/settings instead of etc. This
797 reflects the layout with the Debian package layout.
799 Settings may be posted for command=settings. The POSTed settings must
800 have root element 'settings' like regular setting files. In order to be
801 recognized, the POST request must use Content-Type=text/xml.
803 A service may be posted for command=init. This service will be used
804 during the session. The service may have its own target settings,
805 ICU config, timeout, etc. In order to be recognized, the POST request
806 must use Content-Type=text/xml.
808 Timeout values may be given per-service. That's element 'timeout'
809 which takes three attribute values (a subset may be given): 'session',
810 'z3950_operation', 'z3950_session'. Option -T is no longer supported
811 - used to specify session timeout.
813 Option -t tests the Pazpar2 configuration and returns exit code
814 (0=success, non-zero=failure). In previous version of Pazpar2, -t
815 specified local settings.
817 In version 1.2.0 the configuration file - after include processing -
818 was dumped to stdout. Now, the configuration is only dumped to the
819 yaz log file if option -d is given.
823 Configuration may now have multiple server areas. This means that a
824 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
825 yet supported - on a server basis. Configuration may also have multiple
826 services .. That is repeating service elements inside a server. Each
827 has an attribute 'id' which serves as service ID. This ID in turn may
828 be used in a Pazpar2 session, by specifying parameter service=ID for
829 command init. There can be at most one unnamed service inside a server
830 which can be referred to by not specifying an service ID for command
831 init (backwards compatible). In order to partition multiple servers and
832 services a new include directive has been added. This takes an attribute
833 'src' which specifies one or more sub-files. For example to include
834 service files, one might use:
835 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
836 It is the intention that that completely makes the settings directive
839 Fix problem where the record command would wait forever if there were
840 no targets to wait for (activeclients == 0).
844 One result set is created per session (last search) rather than for
845 each connection which happen to be shared (bug #3009).
847 marc21 stylesheets changed for efficiency.
851 Session timeout may be specified on the command-line as option -T.
853 Pazpar2 may now be operated in a no-merged mode for records.. All records
854 will be considered unique. This mode is enabled if no mergekey is
855 generated by the normalization stylesheet (pz:xslt).
857 Pazpar2 caches original records from each target and the 'record' command
858 with offset returns the original record if 'syntax' and 'esn' are NOT
859 specified. This speeds up retrieval of original records but also means
860 that Pazpar2 uses more memory. The cached records will be freed when the
861 session terminates or a new search is executed.
863 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
864 library part of YAZ is used.
866 Added SRU client support.
868 Automatically computes pz:nativesyntax if not provided. Works for XML and
871 --- 1.0.13 2008/11/24
873 Command bytarget returns name of target (if defined).
875 --- 1.0.12 2008/11/04
877 Fixed bug #2021.. location now holds all brief elements.
879 --- 1.0.11 2008/10/15
881 Fixed check for application/x-www-form-urlencoded parameters.
883 --- 1.0.10 2008/10/14
885 Fixes for IE in pz2.js.
887 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
891 Changed the JS library pz2.js to use POST for long URL (+ params).
893 Added installation instructions for Windows. Note: NT services is
894 NOT available until we make a new release of YAZ.
896 Preserve order of repeated metadata fields (they were reversed before).
898 More MARC21 information extracted for metadata.
902 Fixed bug #1162: HTML entities are not escaped properly.
904 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
908 Marc21 stylesheet updated to reflect multiple full text fields
912 Fixed bug in pz2.js WRT DOMElement attributes on IE.
914 Fixed bug 2100: Database wildcards not working
918 Added support for retrieval of records in binary.
920 Fixed bug 1794: Pazpar2 does not return valid XML.
922 Deal with ICU not returning sortkey (resulted in SEGV before).
926 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
927 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
929 Improved diagnostics when Pazpar2 HTTP decoding fails.
931 Pazpar2 requests may be POSTed as using Content-Type
932 application/x-www-form-urlencoded.
934 Pazpar2 honors LF in HTTP headers.
936 Handle targets that handle negative hit counts (should not happen, but it
941 ICU is used for tokenization and normalization of the following: mergekey,
942 sorting, relevance terms.
944 Debian package now enables ICU tokenization and normalization by default.
948 Exposed user setting values (i.e. non-pz: names) to the record systems in two
949 ways: Either as parameters to the normalization stylesheets (which would allow the
950 programmer to postprocess or use the values in any way) or after the normalization
951 step, in which case values are made part of the normalized record (and available for
952 sorting, termlists, display, or other interface-related use.
954 Implemented sorting by year.
956 Option -d dumps records to the current log file instead of stderr.
958 Fixes for compilation on cygwin.
960 Z39.50 client code uses pz:elements. pz:elements was recognized in
961 earlier Pazpar2 versions but it was not used for anything.
963 icu_chain_test is using fgets instead of getline - fixes compilation
966 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
967 query conversions fail (rather than _any_). This means targets that do
968 not support some fields are ignored in a search.
972 Improved handling of socket timeout for Z39.50 connections.
974 Misc documentation updates and spell fixes.
976 Debian package pazpar2 creates log rotate entry.
978 Debian package pazpar2-apache2 reloads Apache2.
980 jsdemo included in distribution. It illustrates the use of the js/pz2.js
985 First public release.
