3 Experimental support for snippets. If argument snippets=1 is given
4 for command record or show, the text will include <match>-tags for
5 those area that matches.
7 Fix memory leak WRT client structures (incorrect inc ref count).
9 Log when a HTTP response is serialized and the time elapsed.
11 New command, service, which returns current service XML in use for
16 Local limit for fields of type "generic" (ie text fields) are
17 now normalized by mergekey rule before comparison takes place.
18 Before, no normalization took place and comparsion was, thus, exact.
20 New facility: dynamic rank , which allows ranking to be changed
21 for an existing result set. The rank can be set for search or
22 show. This overrides the rank for metadata elements (which fields
25 New facility:dynamic mergekey , which allows mergekey to be changed
26 for an existing result set. The mergekey can be set for search or
29 HTTP server: host=@ listens on IPV6 and IPV4 if possible.
30 Also, allow ports to be given as names (not just integers).
31 Fix @-notation on systems that don't support IPV6 sockets.
35 Add MasterKey Connect configuration. Refer to section "non-standard
36 databases" for more information.
38 Allow timeformat for log to be specified with option -m (as Metaproxy
41 New Debian package pazpar2-dbg.
43 Fix NULL ptr reference of se->relevance. If a new search is initiated
44 and a CCL query fails to parse, Pazpar2 could crash.
46 Fix problem with host/port mangling in Pazpar2 HTTP server. Problem
47 existed in 1.6.29 only.
51 IPV6 updates. Allow IPv6 addresses for database hosts and IPv6 address
52 for HTTP server. By default the HTTP server uses IPv4 only, but that can be
53 changed by setting "host" attribute for the "listen" element.
55 Change semantics of pz:extendrecs. Allow for repeated fetches .
56 pz:extendrecs is now the number of extra records to fetch (was total
61 Fix hang or memory violation if show occurred before a search. (not that
62 it makes much sense to perform a show before a search).
66 pz2.js: Element_parseChildNodes concatenates all Text/CDATA nodes, instead
71 New pz:metadata attribute, empty="empty-value" for Pazpar2's
72 internal representation. With this attribute, Pazpar2 treates an empty
73 pz:metadata type as having the value for "empty" - if empty.
75 New setting, pz:extendrecs, which triggers extended fetch of records
76 for a database beyond pz:maxrecs for a show command.
78 Fix warning that was falsely issued for "missing limitmap".
80 Log message for Pazpart start/stop changed. Now using same style as
81 Metaproxy, ie Pazpar2 start SHA1 / Pazpar2 stop .
85 Fix hang of 2nd command=show with esn/syntax given.
89 New merge attribute type: 'first', which takes all metadata fields
90 from first target that returns the particular field.
94 Extend info command with hostname and YAZ SHA1
95 Indent results for both command stat and info.
97 Allow limit on merged content. The new configuration metadata
98 element, limitcluster, configures that a metadata element (name) be used
99 as limit name for search. Applies to the whole service (ie all targets),
100 unlike pz:limitmap which is configured per-target (database).
102 New feature: limitmap local:* matches against all metadata fields.
104 Allow repeated list in limitmap spec . Separated by comma. For
105 example: value="local:title,rpn:@attr 1=4".
107 New element <message> in bytarget response. Holds diagnostic message
108 of code (say 'Unsupported Use Attribute' for Bib-1 114).
110 Improved logging for record ingestion failures.
112 Avoid using struct icu_chain in non-YAZ_HAVE_ICU mode. In the rare case,
113 when YAZ is compiled without ICU support.
115 --- 1.6.22 2012/10/11
117 Requires YAZ-4.2.40 to support native solr support.
119 Fix and improve logic handling whether or not to re-do search on sort
120 order changes. A sort order with change in ascending/descending only
121 whould not trigger a new search, which is required for targets with
122 native sorting capabilities. Each client is now checked if instructions
123 (sortmap) exist for native sorting and only client that does requires
124 it is researched. Other clients is just re-ingesting the records,
125 they already have. The resultset is now cleared if any researching
128 Connection sharing between session has broken since version 1.6.8 with
129 introduction of logic that would minimize searching if pazpar2 could
130 detect this based on same query and limits and partly sort order.
131 This could lead to segementations violations.
133 Added a chapter in the manaul about relevance ranking.
135 --- 1.6.21 2012/09/24
137 Rank tweak: follow=number will increase mult by number if two terms
138 occur next to each other; number-1 if they are one term apart , .. 0
139 if they are number a part (all in order). Default is 0 (following
140 terms has no effect).
142 Rank tweak: lead=k will divide mult by 1 + log2(1+k*l) where k is
143 value given by lead and l is length from beginning of field where
144 term occurs (l=0 for first term, l=1 for second term, ..). Default
147 Rank tweak: length=strategy. length="linear" if mult is to be divided
148 by length (existing, default behavior), length="log" if mult is to be
149 divided by log2(1+length), length="none" if mult is not to be affected
152 --- 1.6.20 2012/09/21
154 Rank algorithm details may be printed as part of show response in
155 element <relevance_info>.. This is only printed if <rank debug="yes"/>
158 Record as returned by show/record command have a minimal indentation
159 which makes things human-readable.
161 New configuration of default sorting criteria (sort-default) in
162 service definition. If no criteria is defined it will be as before
165 Search command now supports sort parameter just as the show command.
166 If no parameter is give, it will use the service sort-default value.
168 --- 1.6.19 2012/09/18
170 Rank algorithm skips strings that gets normalized to empty string.
171 For example, & and ! could map to the empty string. The weight for
172 those terms is now 0 (as if they were not part of the query).
174 Rank algorithm does not use CCL from limitmap; only from the query
175 parameter (user query).
179 --- 1.6.18 2012/09/17
181 Rank algorithm configurable by 'rank' element inside service. So far
182 only, attribute 'cluster' is recognized. If cluster="yes", multiple
183 records inside a cluster boosts higher than single records. This
184 is default behavior and existing behavior. cluster="no" takes the
185 average score of each record in a cluster.
187 --- 1.6.17 2012/09/05
189 Fix bad re-use of connections (connections with changing proxy should not
192 --- 1.6.16 2012/08/22
194 Fix a bug introduce in 1.6.15 around the position sorting. It resetted the
195 resultset and sorting when the sort order is position. However this will be done on
196 every client poll, which will make pazpar2 continuing reset and fetching.
197 It should only be done on FIRST request where the sort order change.
199 Fix an issue on suggestion option: Also disable suggestions on empty string.
201 Clean up in turbo marc stylesheet.
203 Remove the hardcoded size of termlists.
205 --- 1.6.15 2012/06/27
207 New facility: ccldirective may be given in service definition. Allows
208 CCL parsing to be customized a bit, such as defining names of operators
211 New facility: raw record by checksum, rather than offset. The record
212 command optionally takes checksum which identifies certain record from
215 New facility: per field ranking. Rank may be given as M [F N] where
216 M is default rank and N is rank for CCL terms from field F.
218 --- 1.6.14 2012/06/04
220 Fix for IE7/8 in pz.js
222 Applied patch from Giannis Kosmas on keepAlive, which also adds keepAlive to init response.
224 Lower log level some places.
226 Remove some invalid test results.
228 --- 1.6.13 2012/05/23
230 Introducing a version=2 parameter for show, termlist and bytarget commands.
231 This enables pazpar2 to return approximation on hit and count count when
232 doing record filtering using the limit parameter on search and a
233 limitmap with a value of "local:"
235 Setting pz:xslt may embed local XSLT as an alternative to referring
237 Value is not CDATA but XML nodes embedded, so escaping is not necessary
238 but a root element *must* be present. For example:
239 <settings target="target="z3950.indexdata.com/marc">
248 Metadata field rank may given by XML internal document (pz:xslt
249 result). If rank is not given, the rank from service description is
252 Metadata field can now configured a default limitmap and facetmap.
253 Setting limitmap to "local:" would work for all kind of targets, but would
254 prob. not be the optimal solution. But at least better than the default behavior
255 of pazpar2 where no filtering is done.
257 A service definition can now also contains <set/> that defines service-wide
258 settings. These will override server-wide sets and will be overridded by
261 New setting, pz:present_chunk, that specifies number of records to fetch
262 at a time. Zero will disable chunkation; will fetch max_records at once.
264 --- 1.6.12 2012/03/14
266 Revert the format change in termlist response, that could break
267 some clients / UIs since they were expecting an (empty) element
268 if no facet values was found.
270 --- 1.6.11 2012/03/07
272 Revert the behavior of returning errors when unable to block
273 on termlist, bytarget and search, when unable to block due to
274 other block. The client will now receive a regular response,
275 but it will be logged in the server. A parameter (report) is
276 added to change behavior to return error response or WARNING
277 status message. Consider this "API" as private, as it is mostly
278 untested and could be changed in future releases.
280 Fix spell error in pz2.js fix in 1.6.10.
282 New Marc2TurboMarc.xsl (contribution from Sven Porst).
283 Can solve the missing marc21.xsl updates in some cases.
285 tmarc.xsl: Simplify the 6xx to subject-long and fix 1-based
286 substring (contribtion from Sven Porst)
288 marc21.xsl: fix 1-based substring call
290 tmarc.xsl and marc21.xsl: use 856$a as last option for electronic-text.
292 Add test_termlist_block to test suite
294 --- 1.6.10 2012/02/23
296 Fix SEGV for invalid PQFs and SRU/SOLR targets
297 Also refactor a bit the code that converts from PQF to SRU/SOLR queries.
299 Fix pz2.js: "null object" due to change in in bytarget result XML.
301 Fixes in tmarc.xsl: Subject-long shorten for extra commas only.
302 Added this normalization to the other subject-long fields (d6xx),
303 where it was missing.
305 Fixes in marc21.xsl: Updated with most of the new tmarc.xsl.
306 Still differences around medium and holdings. marc21.xsl is not
307 longer active used by Index Data, and should be considered unsupported.
308 Use tmarc.xsl instead.
312 Fix SEGV that could occur for failed connections.
316 Fix bug for command sort that could return no results for active clients
317 (from previous search). This bug was present in 1.6.6-1.6.7.
319 Fix bug in results that could include results that should have been
320 filtered out. This bug was present in 1.6.6-1.6.7.
324 Fix bug introduced in 1.6.6 where a connection re-use could stall
327 Local filtering may now specify a local metadata field, eg.
328 pz:limitmap:somefield[t]=local:otherfield
332 For search, when limit and or filtering is in place and search
333 is identical to previous search, the result set is re-used and the
334 target is not searched.
336 Limits may work perform local filtering as well, by using "local:"
341 Updated bytarget command to contain a suggestions element with misspelled
342 words and suggestions to these. pz2.js has been updated to deliver this
343 onwards as well. Only target that currently delivers this is the solr
344 client in YAZ 4.2.18.
348 New service definition element, xslt, that allows an embedded stylesheet
349 to be defined. This can be referred to from pz:xslt as an alternative to
352 New pz:sortmap:field setting for specifying hints on how to make
353 a target natively sort on a field. This is used for command=show in
354 conjunction with sort.
356 New pz:url setting for specifying the actual URL for a target. When
357 this is used the target ID is not used as URL anymore and the target ID
358 may be almost any string (not including []).
360 command=termlist without name parameter returns all termlists/facets.
361 Previously if name parameter was omitted, only "subject" was returned.
365 Make termlist sorting stable. Terms with same frequency are now sorted by
366 their display name. This makes a pretty display and improves our
367 regression test because qsort is not a stable sort.
369 New sort parameter value 'position'. The 'position' sorts merged records
370 by their original position from the remote target. This is primarily useful
371 for debugging and may be used for targets that already perform some kind
372 of relevance ranking. Note that sort by default is decreasing; so to get
373 records in their original order sort=position:1 must be used.
377 tmarc.xsl: yet another 773$g fix. Was broken in 1.6.1 as well.
379 Facility to change working directory for pazpar2 daemon. Option -wdir
380 sets working directory to dir. This facility is useful if core dumps
381 must be saved. In this case, the current working directory must be
382 writable by the running user, such as "nobody".
386 New configuration element <icu_chain> for <server>/<service> which
387 allows a named ICU rule (chain) to be defined. The names relevance,
388 sort, mergekey and facet are used for those operations. The definition
389 <icu_chain id="sort" locale="en"> .. </icu_chain>
391 <sort> <icu_chain locale="en> ... </icu_chain> </sort>
392 And so on.. for relevance, mergekey and facet as well. The latter
393 style is deprecated. The facet terms are normalized by the facet
394 rule by default. This may be changed on a metadata field basis by
395 defining the new attribute 'facetrule' for the metadata element.
397 <icu_chain id="myrule" locale="en"> ... </icu_chain>
398 <metadata name="author" termlist="yes" facetrule="myrule"/>
400 Preserve rorder for merged metadata. Fixes issue as reported by Sven
401 Porst: http://lists.indexdata.dk/pipermail/yazlist/2011-July/003230.html
403 tmarc.xsl: set journal-subpart to 773$ only.
407 Modify the behavior for the limit parameter (first defined in 1.5.7).
408 Mapping of limit searches are now defined by the new configuration item
409 pz:limitmap. Fix a dead-lock problem with the limit parameter.
411 Extend tmarc.xsl to extract 773$g data (OpenURL).
415 ICU default maps remove backquote (`).
417 Command 'search' takes limit parameter (optional). The limit parameter
418 allows a search to be limited one or more facets and the corresponding
419 values. This is for server side filtering.
421 Configure tweak: Use -lm for log(3) if needed
425 Fix a problem with skiparticle sortkey that could be completely
426 ignored (and reduced to "").
428 Fix dependency problem in pazpar2 RPM package (did not require
429 libyaz4 as it should).
433 Fix memory leak that occurred for command=termlist&name=xtargets .
435 Pazpar2 may save HTTP requests. Enabled by option -R.
439 Experimental support for DTIC DADS target. New dads-pz2.xsl.
441 Support for query_syntax (overrides the default for SRU | Z39.50)
443 Support for extraArgs (ZOOM "extraArgs" option) for targets
445 New commands: status-server and status-session
449 Fix for threaded runs: Client now have a copy of the database URL,
450 which can used after the database has been release from the client.
451 This makes the logging in the connection idle timeout of the client nicer (no NOURL) and should be thread-safe.
453 tmarc.xsl: Add journal-title-abbrev and full text.
455 cf.xsl: new fields: isbn, issn, journaltitle, volume, issue
457 Fix for cmd=record before search.
459 Session Logging clean up.
461 Fix wrong termlist factor when maxrecs is different from 100.
465 Fix missing pz:termlist_term_factor in settings.c messed up pz:preferred.
466 Term factor is default enabled but can be diseabled by
467 pz:termlist_term_factor=0
471 Add scaling of facet count. Currently always enabled, needs fixing.
472 Allow user-defined info for target suffix. This has no meaning in
473 Pazpar2 except to distinguish targets from each other. The suffix
474 data begins with #. For example z3950.indexdata.com/gils#Mydata
476 Added exact-match recordfilter; format name=value
480 SOLR support. Pazpar2 may operate as web service client for SOLR.
484 Fix for show command and block=1 (dead lock). Bug was introduced in
489 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
490 tested on CentOS 5.5 only.
494 Fix problem with result sets being removed from a client session
495 if the connection for it was resused by another session. Bug #3489.
497 New iphone UI for Pazpar2 (www/iphone).
501 Fixes for threaded operation.
503 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
505 New example services in etc/services in source. In the Debian packages
506 these are located in /etc/pazpar2/services-available
508 Threaded mode operational on Windows. Requires Windows 7 or Windows
511 Default value of setting pz:max_connections is 0 which means that there
512 is no limit on number of connections.
516 Pazpar2 may operate in threaded mode. Enabled by element threads in
517 the configuration. See pazpar2_conf for details.
519 New setting setting: pz:max_connections. Setting pz:max_connections is
520 a limit of number of sockets to a host. When this limit is reached,
521 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
522 The client will be marked Client_Error when it can not be searched
523 (other clients in a session may work). If pz:max_connections is not set
524 for a target, a value of 30 will be used. Note: the pz:max_connections
525 will only work in threaded mode.
527 pz2.js: JSON support for show.
529 Debian package: Enable default service, default.xml, before starting
530 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
534 Debian version depends on on libyaz4. Note that Pazpar2 will still
535 compile from source with YAZ 3.
537 Split services into separate files. The example configuration file
538 pazpar2.cfg.dist now includes a default service default.xml (part of
539 etc). And default.xml includes settings/edu.xml. The default.xml file,
540 not to be confused with settings/defaults.xml, is a template for jsdemo
541 and other services. The Debian package installs /etc/pazpar2/server.xml
542 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
543 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
544 The default.xml (from etc) is installed in /etc/pazpar2/services-available
545 and a symlink to it is created from services-enabled. The default.xml
546 service is unnamed and, thus, will be used by jsdemo and test1.
548 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
549 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
553 Support for additional fields in cf.xsl and pazpar2.conf.dist:
554 publisher, available, due, location (=locallocation), callno
555 (=callnumber), thumburl and score.
557 Describe pz:xslt and the auto setting.
559 Move mergekey definition away from the normalization stylesheets and
560 define a mergekey common for all target types in pazpar2.cfg.
562 Code update: Use the Odr_int type for hit counts. This is part of
563 YAZ 3.0.47 and later and so configure checks for that.
567 Metadata attribute 'skiparticle' also works for ICU based
568 normalization. (was only working for the non-ICU/ASCII before).
570 Command bytarget with argument settings=1 will show settings per
571 target.. This is to be able to verify correct settings and be able to
572 test that they are correct. The database settings array size is now
573 also stored.. Problems with database settings array is that if not
574 careful it will be too small (smaller than dictionary per-service
577 Make record list sorting stable by comparing mergekey for records if
578 relevance/title or other sorting criteria all match. This is merely to
579 ensure that our regressions tests works (reproducible output).
581 Relevance calculation changes: use a different denominator (length) for
582 per-field relevance scoring.. Instead of length of all ranked fields we
583 now use length of individual fields (as if they were individual "free"
584 text fields). This will ensure that documents with a long field with no
585 match (say description) will not "hurt" a title match.
587 Diagnostic member was not set on connection error. Fixed
591 Command search takes two optional parameters, startecs and maxrecs,
592 that specifies the start offset (0, 1, ...) and maximum number of records
593 to fetch for each target.
595 XSLTs + MARC maps are cached within a session so we don't re-parse
596 them over and over again. Even for a session with a single search
597 there's much to be gained because many targets use the same
600 The metadata attribute 'mergekey' now takes one of three values 'no',
601 'required', 'optional' . And the resulting mergekey from metadata
602 is now ordered in the same way as metadata in the service definition.
603 Older Pazpar2 version use the order in which metadata appeared in a
606 The search argument 'filter' now offers a new operator ~ which does a
607 substring match. The = operator works as before: string match for
608 anything but pz:id, or target match for pz:id.
610 New setting pz:recordfilter. The value of this setting takes the
611 form name[~value]. This setting makes Pazpar2 ignore all retrieved
612 records that do not have the metadata element name with value substring
615 Pazpar2 allows YAZ log level to be set (option -v).
619 For WS responses Pazpar2 creates XML header. Exception: raw record.
621 Setting XML files are now stored in etc/settings instead of etc. This
622 reflects the layout with the Debian package layout.
624 Settings may be posted for command=settings. The POSTed settings must
625 have root element 'settings' like regular setting files. In order to be
626 recognized, the POST request must use Content-Type=text/xml.
628 A service may be posted for command=init. This service will be used
629 during the session. The service may have its own target settings,
630 ICU config, timeout, etc. In order to be recognized, the POST request
631 must use Content-Type=text/xml.
633 Timeout values may be given per-service. That's element 'timeout'
634 which takes three attribute values (a subset may be given): 'session',
635 'z3950_operation', 'z3950_session'. Option -T is no longer supported
636 - used to specify session timeout.
638 Option -t tests the Pazpar2 configuration and returns exit code
639 (0=success, non-zero=failure). In previous version of Pazpar2, -t
640 specified local settings.
642 In version 1.2.0 the configuration file - after include processing -
643 was dumped to stdout. Now, the configuration is only dumped to the
644 yaz log file if option -d is given.
648 Configuration may now have multiple server areas. This means that a
649 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
650 yet supported - on a server basis. Configuration may also have multiple
651 services .. That is repeating service elements inside a server. Each
652 has an attribute 'id' which serves as service ID. This ID in turn may
653 be used in a Pazpar2 session, by specifying parameter service=ID for
654 command init. There can be at most one unnamed service inside a server
655 which can be referred to by not specifying an service ID for command
656 init (backwards compatible). In order to partition multiple servers and
657 services a new include directive has been added. This takes an attribute
658 'src' which specifies one or more sub-files. For example to include
659 service files, one might use:
660 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
661 It is the intention that that completely makes the settings directive
664 Fix problem where the record command would wait forever if there were
665 no targets to wait for (activeclients == 0).
669 One result set is created per session (last search) rather than for
670 each connection which happen to be shared (bug #3009).
672 marc21 stylesheets changed for efficiency.
676 Session timeout may be specified on the command-line as option -T.
678 Pazpar2 may now be operated in a no-merged mode for records.. All records
679 will be considered unique. This mode is enabled if no mergekey is
680 generated by the normalization stylesheet (pz:xslt).
682 Pazpar2 caches original records from each target and the 'record' command
683 with offset returns the original record if 'syntax' and 'esn' are NOT
684 specified. This speeds up retrieval of original records but also means
685 that Pazpar2 uses more memory. The cached records will be freed when the
686 session terminates or a new search is executed.
688 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
689 library part of YAZ is used.
691 Added SRU client support.
693 Automatically computes pz:nativesyntax if not provided. Works for XML and
696 --- 1.0.13 2008/11/24
698 Command bytarget returns name of target (if defined).
700 --- 1.0.12 2008/11/04
702 Fixed bug #2021.. location now holds all brief elements.
704 --- 1.0.11 2008/10/15
706 Fixed check for application/x-www-form-urlencoded parameters.
708 --- 1.0.10 2008/10/14

745 Fixed bug 1794: Pazpar2 does not return valid XML.
747 Deal with ICU not returning sortkey (resulted in SEGV before).
751 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
752 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
754 Improved diagnostics when Pazpar2 HTTP decoding fails.

757 application/x-www-form-urlencoded.

766 ICU is used for tokenization and normalization of the following: mergekey,
767 sorting, relevance terms.
769 Debian package now enables ICU tokenization and normalization by default.
773 Exposed user setting values (i.e. non-pz: names) to the record systems in two
774 ways: Either as parameters to the normalization stylesheets (which would allow the
775 programmer to postprocess or use the values in any way) or after the normalization
776 step, in which case values are made part of the normalized record (and available for
777 sorting, termlists, display, or other interface-related use.
779 Implemented sorting by year.
781 Option -d dumps records to the current log file instead of stderr.
783 Fixes for compilation on cygwin.

788 icu_chain_test is using fgets instead of getline - fixes compilation
791 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
