4 Fix problem with result sets being removed from a client session
5 if the connection for it was resused by another session. Bug #3489.
7 New iphone UI for Pazpar2 (www/iphone).
11 Fixes for threaded operation.
13 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
15 New example services in etc/services in source. In the Debian packages
16 these are located in /etc/pazpar2/services-available
18 Threaded mode operational on Windows. Requires Windows 7 or Windows
21 Default value of setting pz:max_connections is 0 which means that there
22 is no limit on number of connections.
26 Pazpar2 may operate in threaded mode. Enabled by element threads in
27 the configuration. See pazpar2_conf for details.
29 New setting setting: pz:max_connections. Setting pz:max_connections is
30 a limit of number of sockets to a host. When this limit is reached,
31 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
32 The client will be marked Client_Error when it can not be searched
33 (other clients in a session may work). If pz:max_connections is not set
34 for a target, a value of 30 will be used. Note: the pz:max_connections
35 will only work in threaded mode.
37 pz2.js: JSON support for show.
39 Debian package: Enable default service, default.xml, before starting
40 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
44 Debian version depends on on libyaz4. Note that Pazpar2 will still
45 compile from source with YAZ 3.
47 Split services into separate files. The example configuration file
48 pazpar2.cfg.dist now includes a default service default.xml (part of
49 etc). And default.xml includes settings/edu.xml. The default.xml file,
50 not to be confused with settings/defaults.xml, is a template for jsdemo
51 and other services. The Debian package installs /etc/pazpar2/server.xml
52 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
53 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
54 The default.xml (from etc) is installed in /etc/pazpar2/services-available
55 and a symlink to it is created from services-enabled. The default.xml
56 service is unnamed and, thus, will be used by jsdemo and test1.
58 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
59 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
63 Support for additional fields in cf.xsl and pazpar2.conf.dist:
64 publisher, available, due, location (=locallocation), callno
65 (=callnumber), thumburl and score.
67 Describe pz:xslt and the auto setting.
69 Move mergekey definition away from the normalization stylesheets and
70 define a mergekey common for all target types in pazpar2.cfg.
72 Code update: Use the Odr_int type for hit counts. This is part of
73 YAZ 3.0.47 and later and so configure checks for that.
77 Metadata attribute 'skiparticle' also works for ICU based
78 normalization. (was only working for the non-ICU/ASCII before).
80 Command bytarget with argument settings=1 will show settings per
81 target.. This is to be able to verify correct settings and be able to
82 test that they are correct. The database settings array size is now
83 also stored.. Problems with database settings array is that if not
84 careful it will be too small (smaller than dictionary per-service
87 Make record list sorting stable by comparing mergekey for records if
88 relevance/title or other sorting criteria all match. This is merely to
89 ensure that our regressions tests works (reproducible output).
91 Relevance calculation changes: use a different denominator (length) for
92 per-field relevance scoring.. Instead of length of all ranked fields we
93 now use length of individual fields (as if they were individual "free"
94 text fields). This will ensure that documents with a long field with no
95 match (say description) will not "hurt" a title match.
97 Diagnostic member was not set on connection error. Fixed
101 Command search takes two optional parameters, startecs and maxrecs,
102 that specifies the start offset (0, 1, ...) and maximum number of records
103 to fetch for each target.
105 XSLTs + MARC maps are cached within a session so we don't re-parse
106 them over and over again. Even for a session with a single search
107 there's much to be gained because many targets use the same
110 The metadata attribute 'mergekey' now takes one of three values 'no',
111 'required', 'optional' . And the resulting mergekey from metadata
112 is now ordered in the same way as metadata in the service definition.
113 Older Pazpar2 version use the order in which metadata appeared in a
116 The search argument 'filter' now offers a new operator ~ which does a
117 substring match. The = operator works as before: string match for
118 anything but pz:id, or target match for pz:id.
120 New setting pz:recordfilter. The value of this setting takes the
121 form name[~value]. This setting makes Pazpar2 ignore all retrieved
122 records that do not have the metadata element name with value substring
125 Pazpar2 allows YAZ log level to be set (option -v).
129 For WS responses Pazpar2 creates XML header. Exception: raw record.
131 Setting XML files are now stored in etc/settings instead of etc. This
132 reflects the layout with the Debian package layout.
134 Settings may be posted for command=settings. The POSTed settings must
135 have root element 'settings' like regular setting files. In order to be
136 recognized, the POST request must use Content-Type=text/xml.
138 A service may be posted for command=init. This service will be used
139 during the session. The service may have its own target settings,
140 ICU config, timeout, etc. In order to be recognized, the POST request
141 must use Content-Type=text/xml.
143 Timeout values may be given per-service. That's element 'timeout'
144 which takes three attribute values (a subset may be given): 'session',
145 'z3950_operation', 'z3950_session'. Option -T is no longer supported
146 - used to specify session timeout.
148 Option -t tests the Pazpar2 configuration and returns exit code
149 (0=success, non-zero=failure). In previous version of Pazpar2, -t
150 specified local settings.
152 In version 1.2.0 the configuration file - after include processing -
153 was dumped to stdout. Now, the configuration is only dumped to the
154 yaz log file if option -d is given.
158 Configuration may now have multiple server areas. This means that a
159 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
160 yet supported - on a server basis. Configuration may also have multiple
161 services .. That is repeating service elements inside a server. Each
162 has an attribute 'id' which serves as service ID. This ID in turn may
163 be used in a Pazpar2 session, by specifying parameter service=ID for
164 command init. There can be at most one unnamed service inside a server
165 which can be referred to by not specifying an service ID for command
166 init (backwards compatible). In order to partition multiple servers and
167 services a new include directive has been added. This takes an attribute
168 'src' which specifies one or more sub-files. For example to include
169 service files, one might use:
170 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
171 It is the intention that that completely makes the settings directive
174 Fix problem where the record command would wait forever if there were
175 no targets to wait for (activeclients == 0).
179 One result set is created per session (last search) rather than for
180 each connection which happen to be shared (bug #3009).
182 marc21 stylesheets changed for efficiency.
186 Session timeout may be specified on the command-line as option -T.
188 Pazpar2 may now be operated in a no-merged mode for records.. All records
189 will be considered unique. This mode is enabled if no mergekey is
190 generated by the normalization stylesheet (pz:xslt).
192 Pazpar2 caches original records from each target and the 'record' command
193 with offset returns the original record if 'syntax' and 'esn' are NOT
194 specified. This speeds up retrieval of original records but also means
195 that Pazpar2 uses more memory. The cached records will be freed when the
196 session terminates or a new search is executed.
198 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
199 library part of YAZ is used.
201 Added SRU client support.
203 Automatically computes pz:nativesyntax if not provided. Works for XML and
206 --- 1.0.13 2008/11/24
208 Command bytarget returns name of target (if defined).
210 --- 1.0.12 2008/11/04
212 Fixed bug #2021.. location now holds all brief elements.
214 --- 1.0.11 2008/10/15
216 Fixed check for application/x-www-form-urlencoded parameters.
218 --- 1.0.10 2008/10/14
220 Fixes for IE in pz2.js.
222 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
226 Changed the JS library pz2.js to use POST for long URL (+ params).
228 Added installation instructions for Windows. Note: NT services is
229 NOT available until we make a new release of YAZ.
231 Preserve order of repeated metadata fields (they were reversed before).
233 More MARC21 information extracted for metadata.
237 Fixed bug #1162: HTML entities are not escaped properly.
239 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
243 Marc21 stylesheet updated to reflect multiple full text fields
247 Fixed bug in pz2.js WRT DOMElement attributes on IE.
249 Fixed bug 2100: Database wildcards not working
253 Added support for retrieval of records in binary.
255 Fixed bug 1794: Pazpar2 does not return valid XML.
257 Deal with ICU not returning sortkey (resulted in SEGV before).
261 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
262 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
264 Improved diagnostics when Pazpar2 HTTP decoding fails.
266 Pazpar2 requests may be POSTed as using Content-Type
267 application/x-www-form-urlencoded.
269 Pazpar2 honors LF in HTTP headers.
271 Handle targets that handle negative hit counts (should not happen, but it
276 ICU is used for tokenization and normalization of the following: mergekey,
277 sorting, relevance terms.
279 Debian package now enables ICU tokenization and normalization by default.
283 Exposed user setting values (i.e. non-pz: names) to the record systems in two
284 ways: Either as parameters to the normalization stylesheets (which would allow the
285 programmer to postprocess or use the values in any way) or after the normalization
286 step, in which case values are made part of the normalized record (and available for
287 sorting, termlists, display, or other interface-related use.
289 Implemented sorting by year.
291 Option -d dumps records to the current log file instead of stderr.
293 Fixes for compilation on cygwin.
295 Z39.50 client code uses pz:elements. pz:elements was recognized in
296 earlier Pazpar2 versions but it was not used for anything.
298 icu_chain_test is using fgets instead of getline - fixes compilation
301 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
302 query conversions fail (rather than _any_). This means targets that do
303 not support some fields are ignored in a search.
307 Improved handling of socket timeout for Z39.50 connections.
309 Misc documentation updates and spell fixes.
311 Debian package pazpar2 creates log rotate entry.
313 Debian package pazpar2-apache2 reloads Apache2.
315 jsdemo included in distribution. It illustrates the use of the js/pz2.js
320 First public release.
