3 SOLR support. Pazpar2 may operate as web service client for SOLR.
7 Fix for show command and block=1 (dead lock). Bug was introduced in
12 New RPM packages: pazpar2, pazpar2-js, pazpar2-doc. These have been
13 tested on CentOS 5.5 only.
17 Fix problem with result sets being removed from a client session
18 if the connection for it was resused by another session. Bug #3489.
20 New iphone UI for Pazpar2 (www/iphone).
24 Fixes for threaded operation.
26 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
28 New example services in etc/services in source. In the Debian packages
29 these are located in /etc/pazpar2/services-available
31 Threaded mode operational on Windows. Requires Windows 7 or Windows
34 Default value of setting pz:max_connections is 0 which means that there
35 is no limit on number of connections.
39 Pazpar2 may operate in threaded mode. Enabled by element threads in
40 the configuration. See pazpar2_conf for details.
42 New setting setting: pz:max_connections. Setting pz:max_connections is
43 a limit of number of sockets to a host. When this limit is reached,
44 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
45 The client will be marked Client_Error when it can not be searched
46 (other clients in a session may work). If pz:max_connections is not set
47 for a target, a value of 30 will be used. Note: the pz:max_connections
48 will only work in threaded mode.
50 pz2.js: JSON support for show.
52 Debian package: Enable default service, default.xml, before starting
53 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
57 Debian version depends on on libyaz4. Note that Pazpar2 will still
58 compile from source with YAZ 3.
60 Split services into separate files. The example configuration file
61 pazpar2.cfg.dist now includes a default service default.xml (part of
62 etc). And default.xml includes settings/edu.xml. The default.xml file,
63 not to be confused with settings/defaults.xml, is a template for jsdemo
64 and other services. The Debian package installs /etc/pazpar2/server.xml
65 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
66 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
67 The default.xml (from etc) is installed in /etc/pazpar2/services-available
68 and a symlink to it is created from services-enabled. The default.xml
69 service is unnamed and, thus, will be used by jsdemo and test1.
71 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
72 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
76 Support for additional fields in cf.xsl and pazpar2.conf.dist:
77 publisher, available, due, location (=locallocation), callno
78 (=callnumber), thumburl and score.
80 Describe pz:xslt and the auto setting.
82 Move mergekey definition away from the normalization stylesheets and
83 define a mergekey common for all target types in pazpar2.cfg.
85 Code update: Use the Odr_int type for hit counts. This is part of
86 YAZ 3.0.47 and later and so configure checks for that.
90 Metadata attribute 'skiparticle' also works for ICU based
91 normalization. (was only working for the non-ICU/ASCII before).
93 Command bytarget with argument settings=1 will show settings per
94 target.. This is to be able to verify correct settings and be able to
95 test that they are correct. The database settings array size is now
96 also stored.. Problems with database settings array is that if not
97 careful it will be too small (smaller than dictionary per-service
100 Make record list sorting stable by comparing mergekey for records if
101 relevance/title or other sorting criteria all match. This is merely to
102 ensure that our regressions tests works (reproducible output).
104 Relevance calculation changes: use a different denominator (length) for
105 per-field relevance scoring.. Instead of length of all ranked fields we
106 now use length of individual fields (as if they were individual "free"
107 text fields). This will ensure that documents with a long field with no
108 match (say description) will not "hurt" a title match.
110 Diagnostic member was not set on connection error. Fixed
114 Command search takes two optional parameters, startecs and maxrecs,
115 that specifies the start offset (0, 1, ...) and maximum number of records
116 to fetch for each target.
118 XSLTs + MARC maps are cached within a session so we don't re-parse
119 them over and over again. Even for a session with a single search
120 there's much to be gained because many targets use the same
123 The metadata attribute 'mergekey' now takes one of three values 'no',
124 'required', 'optional' . And the resulting mergekey from metadata
125 is now ordered in the same way as metadata in the service definition.
126 Older Pazpar2 version use the order in which metadata appeared in a
129 The search argument 'filter' now offers a new operator ~ which does a
130 substring match. The = operator works as before: string match for
131 anything but pz:id, or target match for pz:id.
133 New setting pz:recordfilter. The value of this setting takes the
134 form name[~value]. This setting makes Pazpar2 ignore all retrieved
135 records that do not have the metadata element name with value substring
138 Pazpar2 allows YAZ log level to be set (option -v).
142 For WS responses Pazpar2 creates XML header. Exception: raw record.
144 Setting XML files are now stored in etc/settings instead of etc. This
145 reflects the layout with the Debian package layout.
147 Settings may be posted for command=settings. The POSTed settings must
148 have root element 'settings' like regular setting files. In order to be
149 recognized, the POST request must use Content-Type=text/xml.
151 A service may be posted for command=init. This service will be used
152 during the session. The service may have its own target settings,
153 ICU config, timeout, etc. In order to be recognized, the POST request
154 must use Content-Type=text/xml.
156 Timeout values may be given per-service. That's element 'timeout'
157 which takes three attribute values (a subset may be given): 'session',
158 'z3950_operation', 'z3950_session'. Option -T is no longer supported
159 - used to specify session timeout.
161 Option -t tests the Pazpar2 configuration and returns exit code
162 (0=success, non-zero=failure). In previous version of Pazpar2, -t
163 specified local settings.
165 In version 1.2.0 the configuration file - after include processing -
166 was dumped to stdout. Now, the configuration is only dumped to the
167 yaz log file if option -d is given.
171 Configuration may now have multiple server areas. This means that a
172 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
173 yet supported - on a server basis. Configuration may also have multiple
174 services .. That is repeating service elements inside a server. Each
175 has an attribute 'id' which serves as service ID. This ID in turn may
176 be used in a Pazpar2 session, by specifying parameter service=ID for
177 command init. There can be at most one unnamed service inside a server
178 which can be referred to by not specifying an service ID for command
179 init (backwards compatible). In order to partition multiple servers and
180 services a new include directive has been added. This takes an attribute
181 'src' which specifies one or more sub-files. For example to include
182 service files, one might use:
183 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
184 It is the intention that that completely makes the settings directive
187 Fix problem where the record command would wait forever if there were
188 no targets to wait for (activeclients == 0).
192 One result set is created per session (last search) rather than for
193 each connection which happen to be shared (bug #3009).
195 marc21 stylesheets changed for efficiency.
199 Session timeout may be specified on the command-line as option -T.
201 Pazpar2 may now be operated in a no-merged mode for records.. All records
202 will be considered unique. This mode is enabled if no mergekey is
203 generated by the normalization stylesheet (pz:xslt).
205 Pazpar2 caches original records from each target and the 'record' command
206 with offset returns the original record if 'syntax' and 'esn' are NOT
207 specified. This speeds up retrieval of original records but also means
208 that Pazpar2 uses more memory. The cached records will be freed when the
209 session terminates or a new search is executed.
211 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
212 library part of YAZ is used.
214 Added SRU client support.
216 Automatically computes pz:nativesyntax if not provided. Works for XML and
219 --- 1.0.13 2008/11/24
221 Command bytarget returns name of target (if defined).
223 --- 1.0.12 2008/11/04
225 Fixed bug #2021.. location now holds all brief elements.
227 --- 1.0.11 2008/10/15
229 Fixed check for application/x-www-form-urlencoded parameters.
231 --- 1.0.10 2008/10/14
233 Fixes for IE in pz2.js.
235 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
239 Changed the JS library pz2.js to use POST for long URL (+ params).
241 Added installation instructions for Windows. Note: NT services is
242 NOT available until we make a new release of YAZ.
244 Preserve order of repeated metadata fields (they were reversed before).
246 More MARC21 information extracted for metadata.
250 Fixed bug #1162: HTML entities are not escaped properly.
252 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
256 Marc21 stylesheet updated to reflect multiple full text fields
260 Fixed bug in pz2.js WRT DOMElement attributes on IE.
262 Fixed bug 2100: Database wildcards not working
266 Added support for retrieval of records in binary.
268 Fixed bug 1794: Pazpar2 does not return valid XML.
270 Deal with ICU not returning sortkey (resulted in SEGV before).
274 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
275 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
277 Improved diagnostics when Pazpar2 HTTP decoding fails.
279 Pazpar2 requests may be POSTed as using Content-Type
280 application/x-www-form-urlencoded.
282 Pazpar2 honors LF in HTTP headers.
284 Handle targets that handle negative hit counts (should not happen, but it
289 ICU is used for tokenization and normalization of the following: mergekey,
290 sorting, relevance terms.
292 Debian package now enables ICU tokenization and normalization by default.
296 Exposed user setting values (i.e. non-pz: names) to the record systems in two
297 ways: Either as parameters to the normalization stylesheets (which would allow the
298 programmer to postprocess or use the values in any way) or after the normalization
299 step, in which case values are made part of the normalized record (and available for
300 sorting, termlists, display, or other interface-related use.
302 Implemented sorting by year.
304 Option -d dumps records to the current log file instead of stderr.
306 Fixes for compilation on cygwin.
308 Z39.50 client code uses pz:elements. pz:elements was recognized in
309 earlier Pazpar2 versions but it was not used for anything.
311 icu_chain_test is using fgets instead of getline - fixes compilation
314 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
315 query conversions fail (rather than _any_). This means targets that do
316 not support some fields are ignored in a search.
320 Improved handling of socket timeout for Z39.50 connections.
322 Misc documentation updates and spell fixes.
324 Debian package pazpar2 creates log rotate entry.
326 Debian package pazpar2-apache2 reloads Apache2.
328 jsdemo included in distribution. It illustrates the use of the js/pz2.js
333 First public release.
