3 Fix problem with result sets being removed from a client session
4 if the connection for it was resused by another session. Bug #3489.
6 New iphone UI for Pazpar2 (www/iphone).
10 Fixes for threaded operation.
12 New stylesheets for TurboMARC: tmarc.xsl and opac_turbomarc.xsl.
14 New example services in etc/services in source. In the Debian packages
15 these are located in /etc/pazpar2/services-available
17 Threaded mode operational on Windows. Requires Windows 7 or Windows
20 Default value of setting pz:max_connections is 0 which means that there
21 is no limit on number of connections.
25 Pazpar2 may operate in threaded mode. Enabled by element threads in
26 the configuration. See pazpar2_conf for details.
28 New setting setting: pz:max_connections. Setting pz:max_connections is
29 a limit of number of sockets to a host. When this limit is reached,
30 Pazpar2 will wait up to 5 seconds for a connection to becomes available.
31 The client will be marked Client_Error when it can not be searched
32 (other clients in a session may work). If pz:max_connections is not set
33 for a target, a value of 30 will be used. Note: the pz:max_connections
34 will only work in threaded mode.
36 pz2.js: JSON support for show.
38 Debian package: Enable default service, default.xml, before starting
39 Pazpar2 only if there is no service already in /etc/pazpar2/services-enabled.
43 Debian version depends on on libyaz4. Note that Pazpar2 will still
44 compile from source with YAZ 3.
46 Split services into separate files. The example configuration file
47 pazpar2.cfg.dist now includes a default service default.xml (part of
48 etc). And default.xml includes settings/edu.xml. The default.xml file,
49 not to be confused with settings/defaults.xml, is a template for jsdemo
50 and other services. The Debian package installs /etc/pazpar2/server.xml
51 which is now the main pazpar2 configuration (used to be called pazpar2.cfg).
52 server.xml includes services from /etc/pazpar2/services-enabled/*.xml .
53 The default.xml (from etc) is installed in /etc/pazpar2/services-available
54 and a symlink to it is created from services-enabled. The default.xml
55 service is unnamed and, thus, will be used by jsdemo and test1.
57 New setting pz:negotiation_charset. Patch from Andrei V. Toutoukine. The
58 new setting pz:negotiation_charset specifies character set for Z39.50 Init.
62 Support for additional fields in cf.xsl and pazpar2.conf.dist:
63 publisher, available, due, location (=locallocation), callno
64 (=callnumber), thumburl and score.
66 Describe pz:xslt and the auto setting.
68 Move mergekey definition away from the normalization stylesheets and
69 define a mergekey common for all target types in pazpar2.cfg.
71 Code update: Use the Odr_int type for hit counts. This is part of
72 YAZ 3.0.47 and later and so configure checks for that.
76 Metadata attribute 'skiparticle' also works for ICU based
77 normalization. (was only working for the non-ICU/ASCII before).
79 Command bytarget with argument settings=1 will show settings per
80 target.. This is to be able to verify correct settings and be able to
81 test that they are correct. The database settings array size is now
82 also stored.. Problems with database settings array is that if not
83 careful it will be too small (smaller than dictionary per-service
86 Make record list sorting stable by comparing mergekey for records if
87 relevance/title or other sorting criteria all match. This is merely to
88 ensure that our regressions tests works (reproducible output).
90 Relevance calculation changes: use a different denominator (length) for
91 per-field relevance scoring.. Instead of length of all ranked fields we
92 now use length of individual fields (as if they were individual "free"
93 text fields). This will ensure that documents with a long field with no
94 match (say description) will not "hurt" a title match.
96 Diagnostic member was not set on connection error. Fixed
100 Command search takes two optional parameters, startecs and maxrecs,
101 that specifies the start offset (0, 1, ...) and maximum number of records
102 to fetch for each target.
104 XSLTs + MARC maps are cached within a session so we don't re-parse
105 them over and over again. Even for a session with a single search
106 there's much to be gained because many targets use the same
109 The metadata attribute 'mergekey' now takes one of three values 'no',
110 'required', 'optional' . And the resulting mergekey from metadata
111 is now ordered in the same way as metadata in the service definition.
112 Older Pazpar2 version use the order in which metadata appeared in a
115 The search argument 'filter' now offers a new operator ~ which does a
116 substring match. The = operator works as before: string match for
117 anything but pz:id, or target match for pz:id.
119 New setting pz:recordfilter. The value of this setting takes the
120 form name[~value]. This setting makes Pazpar2 ignore all retrieved
121 records that do not have the metadata element name with value substring
124 Pazpar2 allows YAZ log level to be set (option -v).
128 For WS responses Pazpar2 creates XML header. Exception: raw record.
130 Setting XML files are now stored in etc/settings instead of etc. This
131 reflects the layout with the Debian package layout.
133 Settings may be posted for command=settings. The POSTed settings must
134 have root element 'settings' like regular setting files. In order to be
135 recognized, the POST request must use Content-Type=text/xml.
137 A service may be posted for command=init. This service will be used
138 during the session. The service may have its own target settings,
139 ICU config, timeout, etc. In order to be recognized, the POST request
140 must use Content-Type=text/xml.
142 Timeout values may be given per-service. That's element 'timeout'
143 which takes three attribute values (a subset may be given): 'session',
144 'z3950_operation', 'z3950_session'. Option -T is no longer supported
145 - used to specify session timeout.
147 Option -t tests the Pazpar2 configuration and returns exit code
148 (0=success, non-zero=failure). In previous version of Pazpar2, -t
149 specified local settings.
151 In version 1.2.0 the configuration file - after include processing -
152 was dumped to stdout. Now, the configuration is only dumped to the
153 yaz log file if option -d is given.
157 Configuration may now have multiple server areas. This means that a
158 Pazpar2 instance may listen on multiple ports. Virtual hosting is not
159 yet supported - on a server basis. Configuration may also have multiple
160 services .. That is repeating service elements inside a server. Each
161 has an attribute 'id' which serves as service ID. This ID in turn may
162 be used in a Pazpar2 session, by specifying parameter service=ID for
163 command init. There can be at most one unnamed service inside a server
164 which can be referred to by not specifying an service ID for command
165 init (backwards compatible). In order to partition multiple servers and
166 services a new include directive has been added. This takes an attribute
167 'src' which specifies one or more sub-files. For example to include
168 service files, one might use:
169 <server >.. <include src=/"etc/pazpar2/conf.d/*.xml"/> .. </server>.
170 It is the intention that that completely makes the settings directive
173 Fix problem where the record command would wait forever if there were
174 no targets to wait for (activeclients == 0).
178 One result set is created per session (last search) rather than for
179 each connection which happen to be shared (bug #3009).
181 marc21 stylesheets changed for efficiency.
185 Session timeout may be specified on the command-line as option -T.
187 Pazpar2 may now be operated in a no-merged mode for records.. All records
188 will be considered unique. This mode is enabled if no mergekey is
189 generated by the normalization stylesheet (pz:xslt).
191 Pazpar2 caches original records from each target and the 'record' command
192 with offset returns the original record if 'syntax' and 'esn' are NOT
193 specified. This speeds up retrieval of original records but also means
194 that Pazpar2 uses more memory. The cached records will be freed when the
195 session terminates or a new search is executed.
197 Pazpar2 no longer uses its own ICU wrapper. Instead the ICU wrapper
198 library part of YAZ is used.
200 Added SRU client support.
202 Automatically computes pz:nativesyntax if not provided. Works for XML and
205 --- 1.0.13 2008/11/24
207 Command bytarget returns name of target (if defined).
209 --- 1.0.12 2008/11/04
211 Fixed bug #2021.. location now holds all brief elements.
213 --- 1.0.11 2008/10/15
215 Fixed check for application/x-www-form-urlencoded parameters.
217 --- 1.0.10 2008/10/14
219 Fixes for IE in pz2.js.
221 Fixed bug #2021: non-merged, brief meta data NOT included for command=show.
225 Changed the JS library pz2.js to use POST for long URL (+ params).
227 Added installation instructions for Windows. Note: NT services is
228 NOT available until we make a new release of YAZ.
230 Preserve order of repeated metadata fields (they were reversed before).
232 More MARC21 information extracted for metadata.
236 Fixed bug #1162: HTML entities are not escaped properly.
238 Native Windows port of Pazpar2. Makefile for Visual Studio provided.
242 Marc21 stylesheet updated to reflect multiple full text fields
246 Fixed bug in pz2.js WRT DOMElement attributes on IE.
248 Fixed bug 2100: Database wildcards not working
252 Added support for retrieval of records in binary.
254 Fixed bug 1794: Pazpar2 does not return valid XML.
256 Deal with ICU not returning sortkey (resulted in SEGV before).
260 JavaScript library pzw2.js throws error if WS response (from Pazpar2 or
261 other) is malformed (non-wellformed XML or missing Pazpar2 OK status).
263 Improved diagnostics when Pazpar2 HTTP decoding fails.
265 Pazpar2 requests may be POSTed as using Content-Type
266 application/x-www-form-urlencoded.
268 Pazpar2 honors LF in HTTP headers.
270 Handle targets that handle negative hit counts (should not happen, but it
275 ICU is used for tokenization and normalization of the following: mergekey,
276 sorting, relevance terms.
278 Debian package now enables ICU tokenization and normalization by default.
282 Exposed user setting values (i.e. non-pz: names) to the record systems in two
283 ways: Either as parameters to the normalization stylesheets (which would allow the
284 programmer to postprocess or use the values in any way) or after the normalization
285 step, in which case values are made part of the normalized record (and available for
286 sorting, termlists, display, or other interface-related use.
288 Implemented sorting by year.
290 Option -d dumps records to the current log file instead of stderr.
292 Fixes for compilation on cygwin.
294 Z39.50 client code uses pz:elements. pz:elements was recognized in
295 earlier Pazpar2 versions but it was not used for anything.
297 icu_chain_test is using fgets instead of getline - fixes compilation
300 Loosen the CCL query parsing so that Pazpar2 only returns error if _all_
301 query conversions fail (rather than _any_). This means targets that do
302 not support some fields are ignored in a search.
306 Improved handling of socket timeout for Z39.50 connections.
308 Misc documentation updates and spell fixes.
310 Debian package pazpar2 creates log rotate entry.
312 Debian package pazpar2-apache2 reloads Apache2.
314 jsdemo included in distribution. It illustrates the use of the js/pz2.js
319 First public release.
