3 Log ingest failures and record failures:
5 Clean up logging PAZ-942
6 Use session lead in more places. Log hits/records/filtered for each
7 target when fetching is complete. Log hit count when a search
8 (response) is received. Remove some less useful log messages.
10 Fix warning about about missing (internal) stylesheet PAZ-956
12 Report number of filtered records in bytarget PAZ-954
14 Cache XML documents as they appear after normalization. The key
15 for the cache is database+record offset. Cache is removed if query
16 is modified for search. This speeds up re-establishing a result set
17 for databases where new query is same previous query.
21 poll: add assert for number of FDs; abort on poll failure
25 Fix hang for 2nd use of target with unresolved DNS PAZ-949
29 Use poll rather than select for main event loop to overcome limit of
30 1024 file descriptors PAZ-947
32 Override setting with same name (do not append) PAZ-945
36 Separate package: pazpar2-xsl PAZ-932
40 Update OPAC stylesheets for availabilityDate PAZ-943
42 Fix too funny startrecs description
44 Fix broken ~ match if filter contains = PAZ-941
48 Add pz:redis option for ZOOM caching using redis. This is an alternative
49 to memcached. Requires YAZ 5.2.0 to work.
53 Re-ingest native facets PAZ-934
55 Fix medium override for solr-pz2.xsl.
59 Fix URL with leading http:// not working PAZ-933
61 Build packages for Ubuntu Trusty Tahr 14.04 LTS
63 cf.xsl: handle medium override AND md field
67 sortmap relevance always uses increasing=1. PAZ-930
69 solr-pz2.xsl: ensure medium is also applied if Solr record do not
72 Fix leak in getaddrinfo usage for HTTP listener. Not a big deal because
73 this code is only executed once.
75 Fix typos is sortmap documentation.
77 Doc: fix misplaced variablelist tag.
81 Doc: update WRT ICU which is configured for YAZ; not Pazpar2.
82 It's been like that since version 1.1.1 from August 2009.
84 Add support for result-set caching via memcached. See description of
85 pz:memcached. Require that Pazpar2 is using YAZ 5.0.12 or later.
87 Add support for a <metadata> container tag. Patfh from Sven Porst.
89 Add support for XInclude in main configuarion file. Patch from Sven Porst.
91 Add client_{lock,unlock} before call to non_block_events in
92 connection_continue. Problem is that if non_block_events fire records,
93 then we will not unlock client at all. And as a result, a dead-lock
98 Avoid removing slash and other characters for generic metadata that
99 looks like a URL (contains ://). PAZ-915
101 pz2.js: Only use XDR when doing CORS. Favor XHR in all other circumstances.
103 Cluster merge fixes. PAZ-901
105 Set client state to "working" when waiting for DNS resolver. PAZ-907
107 Log when session terminates. PAZ-905
109 Fix LSB/HS conformance for /etc/init.d/pazpar2 PAZ-904
110 Debian: add support for /etc/init.d/pazpar2 status
112 --- 1.6.37 2013/11/18
114 Fix 'Record Missing' for command=show PAZ-903
116 Preserve order of records within cluster PAZ-902
118 testing: use yaz-ztest -V if possible and use YAZ in sibling directory
121 Allow clustered records to be ingested during retrieval. PAZ-900
123 Fix void function error which cannot return a value.
125 --- 1.6.36 2013/11/11
127 SRU pz:authentication="a/b" may end up as x-username=a%2Fb PAZ-899
129 Upgrade to debhelper version 7 PAZ-898
131 Package with libyaz5 PAZ-897
133 Better error message for CCL parse errors PAZ-887
135 --- 1.6.35 2013/09/23
137 New target setting: pz:authentication_mode. PAZ-896
139 pazpar2 PRM: pazpar2 runs as user nobody. PAZ-893
141 Strip #-suffix for ZOOM URLs. PAZ-892
143 --- 1.6.34 2013/08/30
145 Fix issue with hanging show/bytarget. Could happen if new search was
146 fired with filter before show from previous show completed.
148 Add 'date' handling for solr-pz2.xsl.
150 --- 1.6.33 2013/08/13
152 pz:authentication may carry user group password. If pz:authentication
153 has at least one blank in it, that forces Pazpar2 to use idPass Z39.50
154 authentication. Two forms are allowed
157 If no blanks are present, open authentication is in use (as before).
159 Fix {prev,next}recid elements that are returned by record
160 command. These were incorrect in versions 1.6.23 thru 1.6.32.
162 --- 1.6.32 2013/06/14
164 Experimental support for snippets. If argument snippets=1 is given
165 for command record or show, the text will include <match>-tags for
166 those area that matches.
168 Fix memory leak WRT client structures (incorrect inc ref count).
170 Log when a HTTP response is serialized and the time elapsed.
172 New command, service, which returns current service XML in use for
175 --- 1.6.31 2013/05/24
177 Local limit for fields of type "generic" (ie text fields) are
178 now normalized by mergekey rule before comparison takes place.
179 Before, no normalization took place and comparsion was, thus, exact.
181 New facility: dynamic rank , which allows ranking to be changed
182 for an existing result set. The rank can be set for search or
183 show. This overrides the rank for metadata elements (which fields
186 New facility:dynamic mergekey , which allows mergekey to be changed
187 for an existing result set. The mergekey can be set for search or
190 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
191 Also, allow ports to be given as names (not just integers).
192 Fix @-notation on systems that don't support IPV6 sockets.
194 --- 1.6.30 2013/04/26
196 Add MasterKey Connect configuration. Refer to section "non-standard
197 databases" for more information.
199 Allow timeformat for log to be specified with option -m (as Metaproxy
202 New Debian package pazpar2-dbg.
204 Fix NULL ptr reference of se->relevance. If a new search is initiated
205 and a CCL query fails to parse, Pazpar2 could crash.
207 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
208 existed in 1.6.29 only.
210 --- 1.6.29 2013/04/05
212 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
213 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
214 changed by setting "host" attribute for the "listen" element.
216 Change semantics of pz:extendrecs. Allow for repeated fetches .
217 pz:extendrecs is now the number of extra records to fetch (was total
220 --- 1.6.28 2013/03/21
222 Fix hang or memory violation if show occurred before a search. (not that
223 it makes much sense to perform a show before a search).
225 --- 1.6.27 2013/03/08
227 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
230 --- 1.6.26 2013/03/08
232 New pz:metadata attribute, empty="empty-value" for Pazpar2's
233 internal representation. With this attribute, Pazpar2 treates an empty
234 pz:metadata type as having the value for "empty" - if empty.
236 New setting, pz:extendrecs, which triggers extended fetch of records
237 for a database beyond pz:maxrecs for a show command.
239 Fix warning that was falsely issued for "missing limitmap".
241 Log message for Pazpart start/stop changed. Now using same style as
242 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
244 --- 1.6.25 2013/02/07
246 Fix hang of 2nd command=show with esn/syntax given.
248 --- 1.6.24 2013/01/18
250 New merge attribute type: 'first', which takes all metadata fields
251 from first target that returns the particular field.
253 --- 1.6.23 2013/01/02
255 Extend info command with hostname and YAZ SHA1
256 Indent results for both command stat and info.
258 Allow limit on merged content. The new configuration metadata
259 element, limitcluster, configures that a metadata element (name) be used
260 as limit name for search. Applies to the whole service (ie all targets),
261 unlike pz:limitmap which is configured per-target (database).
263 New feature: limitmap local:* matches against all metadata fields.
265 Allow repeated list in limitmap spec . Separated by comma. For
266 example: value="local:title,rpn:@attr 1=4".
268 New element <message> in bytarget response. Holds diagnostic message
269 of code (say 'Unsupported Use Attribute' for Bib-1 114).
271 Improved logging for record ingestion failures.
273 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
274 when YAZ is compiled without ICU support.
276 --- 1.6.22 2012/10/11
278 Requires YAZ-4.2.40 to support native solr support.
280 Fix and improve logic handling whether or not to re-do search on sort
281 order changes. A sort order with change in ascending/descending only
282 whould not trigger a new search, which is required for targets with
283 native sorting capabilities. Each client is now checked if instructions
284 (sortmap) exist for native sorting and only client that does requires
285 it is researched. Other clients is just re-ingesting the records,
286 they already have. The resultset is now cleared if any researching
289 Connection sharing between session has broken since version 1.6.8 with
290 introduction of logic that would minimize searching if pazpar2 could
291 detect this based on same query and limits and partly sort order.
292 This could lead to segementations violations.
294 Added a chapter in the manaul about relevance ranking.
296 --- 1.6.21 2012/09/24
298 Rank tweak: follow=number will increase mult by number if two terms
299 occur next to each other; number-1 if they are one term apart , .. 0
300 if they are number a part (all in order). Default is 0 (following
301 terms has no effect).
303 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
304 value given by lead and l is length from beginning of field where
305 term occurs (l=0 for first term, l=1 for second term, ..). Default
308 Rank tweak: length=strategy. length="linear" if mult is to be divided
309 by length (existing, default behavior), length="log" if mult is to be
310 divided by log2(1+length), length="none" if mult is not to be affected
313 --- 1.6.20 2012/09/21
315 Rank algorithm details may be printed as part of show response in
316 element <relevance_info>.. This is only printed if <rank debug="yes"/>
319 Record as returned by show/record command have a minimal indentation
320 which makes things human-readable.
322 New configuration of default sorting criteria (sort-default) in
323 service definition. If no criteria is defined it will be as before
326 Search command now supports sort parameter just as the show command.
327 If no parameter is give, it will use the service sort-default value.
329 --- 1.6.19 2012/09/18
331 Rank algorithm skips strings that gets normalized to empty string.
332 For example, & and ! could map to the empty string. The weight for
333 those terms is now 0 (as if they were not part of the query).
335 Rank algorithm does not use CCL from limitmap; only from the query
336 parameter (user query).
340 --- 1.6.18 2012/09/17
342 Rank algorithm configurable by 'rank' element inside service. So far
343 only, attribute 'cluster' is recognized. If cluster="yes", multiple
344 records inside a cluster boosts higher than single records. This
345 is default behavior and existing behavior. cluster="no" takes the
346 average score of each record in a cluster.
348 --- 1.6.17 2012/09/05
350 Fix bad re-use of connections (connections with changing proxy should not
353 --- 1.6.16 2012/08/22
355 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
356 resultset and sorting when the sort order is position. However this will be done on
357 every client poll, which will make pazpar2 continuing reset and fetching.
358 It should only be done on FIRST request where the sort order change.
360 Fix an issue on suggestion option: Also disable suggestions on empty string.
362 Clean up in turbo marc stylesheet.
364 Remove the hardcoded size of termlists.
366 --- 1.6.15 2012/06/27
368 New facility: ccldirective may be given in service definition. Allows
369 CCL parsing to be customized a bit, such as defining names of operators
372 New facility: raw record by checksum, rather than offset. The record
373 command optionally takes checksum which identifies certain record from
376 New facility: per field ranking. Rank may be given as M [F N] where
377 M is default rank and N is rank for CCL terms from field F.
379 --- 1.6.14 2012/06/04
381 Fix for IE7/8 in pz.js
383 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
385 Lower log level some places.
387 Remove some invalid test results.
389 --- 1.6.13 2012/05/23
391 Introducing a version=2 parameter for show, termlist and bytarget commands.
392 This enables pazpar2 to return approximation on hit and count count when
393 doing record filtering using the limit parameter on search and a
394 limitmap with a value of "local:"
396 Setting pz:xslt may embed local XSLT as an alternative to referring
398 Value is not CDATA but XML nodes embedded, so escaping is not necessary
399 but a root element *must* be present. For example:
400 <settings target="target="z3950.indexdata.com/marc">
409 Metadata field rank may given by XML internal document (pz:xslt
410 result). If rank is not given, the rank from service description is
413 Metadata field can now configured a default limitmap and facetmap.
414 Setting limitmap to "local:" would work for all kind of targets, but would
415 prob. not be the optimal solution. But at least better than the default behavior
416 of pazpar2 where no filtering is done.
418 A service definition can now also contains <set/> that defines service-wide
419 settings. These will override server-wide sets and will be overridded by
422 New setting, pz:present_chunk, that specifies number of records to fetch
423 at a time. Zero will disable chunkation; will fetch max_records at once.
425 --- 1.6.12 2012/03/14
427 Revert the format change in termlist response, that could break
428 some clients / UIs since they were expecting an (empty) element
429 if no facet values was found.
431 --- 1.6.11 2012/03/07
433 Revert the behavior of returning errors when unable to block
434 on termlist, bytarget and search, when unable to block due to
435 other block. The client will now receive a regular response,
436 but it will be logged in the server. A parameter (report) is
437 added to change behavior to return error response or WARNING
438 status message. Consider this "API" as private, as it is mostly
439 untested and could be changed in future releases.
441 Fix spell error in pz2.js fix in 1.6.10.
443 New Marc2TurboMarc.xsl (contribution from Sven Porst).
444 Can solve the missing marc21.xsl updates in some cases.
446 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
447 substring (contribtion from Sven Porst)
449 marc21.xsl: fix 1-based substring call
451 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
453 Add test_termlist_block to test suite
455 --- 1.6.10 2012/02/23
457 Fix SEGV for invalid PQFs and SRU/SOLR targets
458 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
460 Fix pz2.js: "null object" due to change in in bytarget result XML.
462 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
463 Added this normalization to the other subject-long fields (d6xx),
464 where it was missing.
466 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
467 Still differences around medium and holdings. marc21.xsl is not
468 longer active used by Index Data, and should be considered unsupported.
469 Use tmarc.xsl instead.
473 Fix SEGV that could occur for failed connections.
477 Fix bug for command sort that could return no results for active clients
478 (from previous search). This bug was present in 1.6.6-1.6.7.
480 Fix bug in results that could include results that should have been
481 filtered out. This bug was present in 1.6.6-1.6.7.
485 Fix bug introduced in 1.6.6 where a connection re-use could stall
488 Local filtering may now specify a local metadata field, eg.
489 pz:limitmap:somefield[t]=local:otherfield
493 For search, when limit and or filtering is in place and search
494 is identical to previous search, the result set is re-used and the
495 target is not searched.
497 Limits may work perform local filtering as well, by using "local:"
502 Updated bytarget command to contain a suggestions element with misspelled
503 words and suggestions to these. pz2.js has been updated to deliver this
504 onwards as well. Only target that currently delivers this is the solr
505 client in YAZ 4.2.18.
509 New service definition element, xslt, that allows an embedded stylesheet
510 to be defined. This can be referred to from pz:xslt as an alternative to
513 New pz:sortmap:field setting for specifying hints on how to make
514 a target natively sort on a field. This is used for command=show in
515 conjunction with sort.
517 New pz:url setting for specifying the actual URL for a target. When
518 this is used the target ID is not used as URL anymore and the target ID
519 may be almost any string (not including []).
521 command=termlist without name parameter returns all termlists/facets.
522 Previously if name parameter was omitted, only "subject" was returned.
526 Make termlist sorting stable. Terms with same frequency are now sorted by
527 their display name. This makes a pretty display and improves our
528 regression test because qsort is not a stable sort.
530 New sort parameter value 'position'. The 'position' sorts merged records
531 by their original position from the remote target. This is primarily useful
532 for debugging and may be used for targets that already perform some kind
533 of relevance ranking. Note that sort by default is decreasing; so to get
534 records in their original order sort=position:1 must be used.
538 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
540 Facility to change working directory for pazpar2 daemon. Option -wdir
541 sets working directory to dir. This facility is useful if core dumps
542 must be saved. In this case, the current working directory must be
543 writable by the running user, such as "nobody".
547 New configuration element <icu_chain> for <server>/<service> which
548 allows a named ICU rule (chain) to be defined. The names relevance,
549 sort, mergekey and facet are used for those operations. The definition
550 <icu_chain id="sort" locale="en"> .. </icu_chain>
552 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
553 And so on.. for relevance, mergekey and facet as well. The latter
554 style is deprecated. The facet terms are normalized by the facet
555 rule by default. This may be changed on a metadata field basis by
556 defining the new attribute 'facetrule' for the metadata element.
558 <icu_chain id="myrule" locale="en"> ... </icu_chain>
559 <metadata name="author" termlist="yes" facetrule="myrule"/>
561 Preserve rorder for merged metadata. Fixes issue as reported by Sven
562 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
564 tmarc.xsl: set journal-subpart to 773$ only.
568 Modify the behavior for the limit parameter (first defined in 1.5.7).
569 Mapping of limit searches are now defined by the new configuration item
570 pz:limitmap. Fix a dead-lock problem with the limit parameter.
572 Extend tmarc.xsl to extract 773$g data (OpenURL).
576 ICU default maps remove backquote (`).
578 Command 'search' takes limit parameter (optional). The limit parameter
579 allows a search to be limited one or more facets and the corresponding
580 values. This is for server side filtering.
582 Configure tweak: Use -lm for log(3) if needed
586 Fix a problem with skiparticle sortkey that could be completely
587 ignored (and reduced to "").
589 Fix dependency problem in pazpar2 RPM package (did not require
590 libyaz4 as it should).
594 Fix memory leak that occurred for command=termlist&name=xtargets .
596 Pazpar2 may save HTTP requests. Enabled by option -R.
600 Experimental support for DTIC DADS target. New dads-pz2.xsl.
602 Support for query_syntax (overrides the default for SRU | Z39.50)
604 Support for extraArgs (ZOOM "extraArgs" option) for targets
606 New commands: status-server and status-session
610 Fix for threaded runs: Client now have a copy of the database URL,
611 which can used after the database has been release from the client.
612 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
614 tmarc.xsl: Add journal-title-abbrev and full text.
616 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
618 Fix for cmd=record before search.
620 Session Logging clean up.
622 Fix wrong termlist factor when maxrecs is different from 100.
626 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
627 Term factor is default enabled but can be diseabled by
628 pz:termlist_term_factor=0
632 Add scaling of facet count. Currently always enabled, needs fixing.
633 Allow user-defined info for target suffix. This has no meaning in
634 Pazpar2 except to distinguish targets from each other. The suffix
635 data begins with #. For example z3950.indexdata.com/gils#Mydata
637 Added exact-match recordfilter; format name=value
641 SOLR support. Pazpar2 may operate as web service client for SOLR.
645 Fix for show command and block=1 (dead lock). Bug was introduced in
650 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
651 tested on CentOS 5.5 only.
655 Fix problem with result sets being removed from a client session
656 if the connection for it was resused by another session. Bug #3489.
658 New iphone UI for Pazpar2 (www/iphone).
662 Fixes for threaded operation.
664 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
666 New example services in etc/services in source. In the Debian packages
667 these are located in /etc/pazpar2/services-available
669 Threaded mode operational on Windows. Requires Windows 7 or Windows
672 Default value of setting pz:max_connections is 0 which means that there
673 is no limit on number of connections.
677 Pazpar2 may operate in threaded mode. Enabled by element threads in
678 the configuration. See pazpar2_conf for details.
680 New setting setting: pz:max_connections. Setting pz:max_connections is
681 a limit of number of sockets to a host. When this limit is reached,
682 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
683 The client will be marked Client_Error when it can not be searched
684 (other clients in a session may work). If pz:max_connections is not set
685 for a target, a value of 30 will be used. Note: the pz:max_connections
686 will only work in threaded mode.
688 pz2.js: JSON support for show.
690 Debian package: Enable default service, default.xml, before starting
691 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
695 Debian version depends on on libyaz4. Note that Pazpar2 will still
696 compile from source with YAZ 3.
698 Split services into separate files. The example configuration file
699 pazpar2.cfg.dist now includes a default service default.xml (part of
700 etc). And default.xml includes settings/edu.xml. The default.xml file,
701 not to be confused with settings/defaults.xml, is a template for jsdemo
702 and other services. The Debian package installs /etc/pazpar2/server.xml
703 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
704 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
705 The default.xml (from etc) is installed in /etc/pazpar2/services-available
706 and a symlink to it is created from services-enabled. The default.xml
707 service is unnamed and, thus, will be used by jsdemo and test1.
709 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
710 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
714 Support for additional fields in cf.xsl and pazpar2.conf.dist:
715 publisher, available, due, location (=locallocation), callno
716 (=callnumber), thumburl and score.
718 Describe pz:xslt and the auto setting.
720 Move mergekey definition away from the normalization stylesheets and
721 define a mergekey common for all target types in pazpar2.cfg.
723 Code update: Use the Odr_int type for hit counts. This is part of
724 YAZ 3.0.47 and later and so configure checks for that.
728 Metadata attribute 'skiparticle' also works for ICU based
729 normalization. (was only working for the non-ICU/ASCII before).
731 Command bytarget with argument settings=1 will show settings per
732 target.. This is to be able to verify correct settings and be able to
733 test that they are correct. The database settings array size is now
734 also stored.. Problems with database settings array is that if not
735 careful it will be too small (smaller than dictionary per-service
738 Make record list sorting stable by comparing mergekey for records if
739 relevance/title or other sorting criteria all match. This is merely to
740 ensure that our regressions tests works (reproducible output).
742 Relevance calculation changes: use a different denominator (length) for
743 per-field relevance scoring.. Instead of length of all ranked fields we
744 now use length of individual fields (as if they were individual "free"
745 text fields). This will ensure that documents with a long field with no
746 match (say description) will not "hurt" a title match.
748 Diagnostic member was not set on connection error. Fixed
752 Command search takes two optional parameters, startecs and maxrecs,
753 that specifies the start offset (0, 1, ...) and maximum number of records
754 to fetch for each target.
756 XSLTs + MARC maps are cached within a session so we don't re-parse
757 them over and over again. Even for a session with a single search
758 there's much to be gained because many targets use the same
761 The metadata attribute 'mergekey' now takes one of three values 'no',
762 'required', 'optional' . And the resulting mergekey from metadata
763 is now ordered in the same way as metadata in the service definition.
764 Older Pazpar2 version use the order in which metadata appeared in a
767 The search argument 'filter' now offers a new operator ~ which does a
768 substring match. The = operator works as before: string match for
769 anything but pz:id, or target match for pz:id.
771 New setting pz:recordfilter. The value of this setting takes the
772 form name[~value]. This setting makes Pazpar2 ignore all retrieved
773 records that do not have the metadata element name with value substring
776 Pazpar2 allows YAZ log level to be set (option -v).
780 For WS responses Pazpar2 creates XML header. Exception: raw record.
782 Setting XML files are now stored in etc/settings instead of etc. This
783 reflects the layout with the Debian package layout.
785 Settings may be posted for command=settings. The POSTed settings must
786 have root element 'settings' like regular setting files. In order to be
787 recognized, the POST request must use Content-Type=text/xml.
789 A service may be posted for command=init. This service will be used
790 during the session. The service may have its own target settings,
791 ICU config, timeout, etc. In order to be recognized, the POST request
792 must use Content-Type=text/xml.
794 Timeout values may be given per-service. That's element 'timeout'
795 which takes three attribute values (a subset may be given): 'session',
796 'z3950_operation', 'z3950_session'. Option -T is no longer supported
797 - used to specify session timeout.
799 Option -t tests the Pazpar2 configuration and returns exit code
800 (0=success, non-zero=failure). In previous version of Pazpar2, -t
801 specified local settings.
803 In version 1.2.0 the configuration file - after include processing -
804 was dumped to stdout. Now, the configuration is only dumped to the
805 yaz log file if option -d is given.
809 Configuration may now have multiple server areas. This means that a
810 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
811 yet supported - on a server basis. Configuration may also have multiple
812 services .. That is repeating service elements inside a server. Each
813 has an attribute 'id' which serves as service ID. This ID in turn may
814 be used in a Pazpar2 session, by specifying parameter service=ID for
815 command init. There can be at most one unnamed service inside a server
816 which can be referred to by not specifying an service ID for command
817 init (backwards compatible). In order to partition multiple servers and
818 services a new include directive has been added. This takes an attribute
819 'src' which specifies one or more sub-files. For example to include
820 service files, one might use:
821 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
822 It is the intention that that completely makes the settings directive
825 Fix problem where the record command would wait forever if there were
826 no targets to wait for (activeclients == 0).
830 One result set is created per session (last search) rather than for
831 each connection which happen to be shared (bug #3009).
833 marc21 stylesheets changed for efficiency.
837 Session timeout may be specified on the command-line as option -T.
839 Pazpar2 may now be operated in a no-merged mode for records.. All records
840 will be considered unique. This mode is enabled if no mergekey is
841 generated by the normalization stylesheet (pz:xslt).
843 Pazpar2 caches original records from each target and the 'record' command
844 with offset returns the original record if 'syntax' and 'esn' are NOT
845 specified. This speeds up retrieval of original records but also means
846 that Pazpar2 uses more memory. The cached records will be freed when the
847 session terminates or a new search is executed.
849 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
850 library part of YAZ is used.
852 Added SRU client support.
854 Automatically computes pz:nativesyntax if not provided. Works for XML and

873 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
877 Changed the JS library pz2.js to use POST for long URL (+ params).
879 Added installation instructions for Windows. Note: NT services is
880 NOT available until we make a new release of YAZ.
882 Preserve order of repeated metadata fields (they were reversed before).
884 More MARC21 information extracted for metadata.
888 Fixed bug #1162: HTML entities are not escaped properly.
890 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
894 Marc21 stylesheet updated to reflect multiple full text fields
898 Fixed bug in pz2.js WRT DOMElement attributes on IE.
900 Fixed bug 2100: Database wildcards not working
904 Added support for retrieval of records in binary.
906 Fixed bug 1794: Pazpar2 does not return valid XML.
908 Deal with ICU not returning sortkey (resulted in SEGV before).
912 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
913 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
915 Improved diagnostics when Pazpar2 HTTP decoding fails.
917 Pazpar2 requests may be POSTed as using Content-Type
918 application/x-www-form-urlencoded.
920 Pazpar2 honors LF in HTTP headers.
922 Handle targets that handle negative hit counts (should not happen, but it
927 ICU is used for tokenization and normalization of the following: mergekey,
928 sorting, relevance terms.
930 Debian package now enables ICU tokenization and normalization by default.
934 Exposed user setting values (i.e. non-pz: names) to the record systems in two
935 ways: Either as parameters to the normalization stylesheets (which would allow the
936 programmer to postprocess or use the values in any way) or after the normalization
937 step, in which case values are made part of the normalized record (and available for
938 sorting, termlists, display, or other interface-related use.
940 Implemented sorting by year.
942 Option -d dumps records to the current log file instead of stderr.
944 Fixes for compilation on cygwin.
946 Z39.50 client code uses pz:elements. pz:elements was recognized in
947 earlier Pazpar2 versions but it was not used for anything.
949 icu_chain_test is using fgets instead of getline - fixes compilation
952 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
953 query conversions fail (rather than _any_). This means targets that do
954 not support some fields are ignored in a search.
958 Improved handling of socket timeout for Z39.50 connections.
960 Misc documentation updates and spell fixes.
962 Debian package pazpar2 creates log rotate entry.
964 Debian package pazpar2-apache2 reloads Apache2.
966 jsdemo included in distribution. It illustrates the use of the js/pz2.js
