3 zooom: relay schema in SRU mode. Previously recordSchema was not affected
8 zoom: new target profile element literalTransform that holds XSLT
9 (encoded as string) for target. Only if present and non-zero length it is
10 considered present. This takes precedence over transform.
12 Don't rely on trang anymore for Git checkout builds. Configuration in etc
13 will only be properly validated if trang is available. From now on only
14 relax NC files are bundled with the source dist.
16 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
17 component was not detected when it should be.
21 z3950_client: mark non-surrogate diagnostics from backend.
23 zoom: a proxy may be specified for HTTP fetch of target profiles.
27 Honor piggyback. Makes some SRU targets behave that insist on
28 maximumRecords > 0, but also increases performance.
32 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
33 file was not update for libdir/metaproxy4 in version 1.3.2.
37 Change location of Metaproxy modules from libdir/metaproxy to
38 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
39 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
41 New facility to dump APDUs from zoom filter. Enabled by
42 <log apdu="true"/> in the zoom filter configuation.
44 zoom filter bug fix: SRU diagnostics received from backend was
45 not properly converted to Bib-1 diagnostics.
47 Package metaproxy depends on libmetaproxy4, same version.
51 zoom: fix a bug WRT passing authentication parameters to backends.
55 Fixes for windows Makefile.
59 Change major version of metaproxy library from 3 to 4. This in turn
60 makes new package names for Debian and RPM.
64 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
67 zoom: configurable element sets for record transforms.
69 zoom: the target profile based transform is specified by element_transform
70 in element torus of of the ZOOM filter configuration ; default value
71 is "pz2". Target profile based retrieval is specified by element_raw
72 in configuration. It will perform same steps, but omit the XSL transform.
73 Default value is "raw".
75 zoom: element set is omitted if not set in profile. But only if pz2
76 transform is in effect. Previously the default element set was to "F".
78 zoom: For non-CF targets database arguments are parsed. User may supply
79 db,user=myuser&password=mypass for non-CF targets. These values override
80 what's given the authentication from the target profile.
82 session_shared: fix reference to freed memory. Would occur if a search
83 response had non-surrogate diagnostics.
87 Route may be given for each port in frontend_net.
91 Documentation for zoom filter. Local target profiles may be specified.
93 Fixes for zoom filter.
97 First version with zoom filter.
101 Filter z3950_client may be configured to always send a close APDU
102 to backend target when connection/session is closed. This will only
103 happen if close APDU is not already sent. Enabled by configuration
104 for z3950_client (force_close).
106 Filter virt_db and multi: relay close APDU.
108 Filter virt_db and multi: relay init size parameters
109 preferredMessageSize and maximumRecordSize.
111 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
115 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
117 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
118 as determined by configure.
120 RPM: Release includes 'indexdata' name. Use indexdata in release name so
121 this package can be distinguished from other vendors.
125 Fix filter multi: relay idAuthentication parameters.
129 Add metaproxy-config for returning compiler flags, libraries.
133 Fix --with-boost=PREFIX .
137 session_shared: fix use of maintenance thread.
139 Introduce 'start' method for filters and routers. It gets called after
140 configure and after fork, but before processing. This changes API -
141 from libmetaproxy2 to libmetaproxy3.
145 session_shared: ensure backend session is closed if init rejected
148 z3950_client: fix NULL ptr reference that could occur if two clients
149 connected concurrently and if max-sockets was in effect.
153 Fix bug 3497 - Metaproxy unstable while stopping.
155 Fix bug 3495 - SEGV in SRU filter.
159 Filter multi throws diagnostic 'Present Out of Range' when
160 appropriate - rather than returning 0 records.
162 Filter virt_db: fix bad result reuse. Could happen if a result
163 was overriden and a backend did not supported named result sets.
167 Filter log: category access logs diagnostics even if searchStatus
168 or presentStatus is 'success'.
172 The SRU to Z39.50 filter does repeated Z39.50 present requests
173 to fetch all records. Needed when a Z39.50 server returns partial
174 results (due to message size limits).
178 Metaproxy now kills all child processes that are spawned by
179 modules (in case of fork, exec).
183 Debian package now installs /etc/metaproxy/metaproxy.xml which
184 includes all XML files /etc/metaproxy/filters-enabled .
185 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
189 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
190 development package to facilitate 3rd party Metaproxy modules.
192 --- 1.0.23 2010/01/04
194 Filter virt_db: Close backend filter session when Init rejected is received
195 from it (in which case it's not really closed yet). This will ensure we don't
196 run out of resources such as FDs in this case.
198 sru_z3950 filter: Accept any database (including those not listed).
200 --- 1.0.22 2009/12/03
202 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
203 later which means YAZ 3.0.47 or later.
205 --- 1.0.20 2009/11/19
207 For filter virt_db, the database is a glob pattern and the virtual
208 database sections are consulted in the order given.
210 --- 1.0.19 2009/07/08
212 For filter multi, the target (for routing) may be given as a glob-pattern.
214 More documentation for filters virt_db and multi.
216 Update schema to allow for no database in sru_z3950 filter.
218 --- 1.0.18 2009/06/30
220 Added limit filter to put sleep (penalty) for heavy use.
222 Filter frontend_net may be configured to limit the number of new connections
223 from same IP to some value (connect-max).
225 Fixed the load_balance filter.
227 --- 1.0.17 2009/06/16
229 Fix path for metaproxy executable for Debian init.d script.
231 --- 1.0.16 2009/06/10
233 SRU to Z39.50 filter honors x-username and x-password. If only
234 x-username is given that translates to open authentication (Z39.50v2). If
235 both x-username and x-password is present that translates to idPass
236 authentication (Z39.50v3).
238 New facility to change current working directory (-w).
240 Update to upstream skeleton of init.d script. Should fix bug #2619.
242 Filter session_shared now caches records (used to only cache connections
245 Filter session_shared now invalidates a Z39.50 session if a server
246 returns -1 hits. This facility was also part of yazproxy and gets around
247 a bug in Voyager-based Z39.50 servers.
249 --- 1.0.15 2008/11/18
251 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
253 --- 1.0.14 2008/06/09
255 Fixed the value of SRU record schema in searchRetrieve response. It was set
256 to a fixed value of "dc" before.
258 Serialize identical SRU requests. This is useful if HTTP client software
259 fires identical requests against metaproxy.
261 Allow Z39.50 target to be specified for SRU requests by using SRU extra
262 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
263 avoid static configuration. This facility is handled by the sru_z3950 module
264 and the z3950_client module.
266 Allow maximum number of sockets to be used for a Z39.50 client by the
267 use of SRU extra parameter x-max-sockets. This facility is handled by the
268 sru_z3950 module and the z3950_client module.
270 --- 1.0.13.1 2008/02/29
272 Simplified check for Boost libraries.
274 --- 1.0.13 2008/02/29
276 First Debian package.
278 The sru_z9350 filter now recognizes SRU parameter z-target as being
279 a ZURL of the form host/database .
281 Mergetype may be specified for filter 'multi'.
283 --- 1.0.12 2007/09/19
285 Fixed problem in Makefile WRT library specifictions. This could produce
286 linker errors (when they should not happen).
288 Fixed bug #1341: MetaProxy returning different results. Problem was that
289 fix-up of record database did not normalize the database name.
291 Documentation updates for Windows compilation.
293 --- 1.0.11 2007/06/14
295 Fixed problem with logfile being truncated.
297 --- 1.0.10 2007/05/23
299 Fixed bug #1136: Access rights not enforced.
301 Extension for log module. The log category 'access' logs more details.
302 New category 'user-access' added which is simlar to 'access' but adds
303 the Z39.50 user as for all entries in a session.
307 Added support for configurable default/force target/vhost for module Z39.50
312 Implemented filter, session_shared, which optimizes usage of Z39.50
313 sessions and result sets.
315 New filter, record_transform, which converts MARC/XML records.
317 New filter, sru_z3950, which converts SRU to Z39.50 packages.
319 New filter, load_balance, in development.
321 New filter, zeerex_xplain.
323 XML framework for config files started.
325 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
326 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
327 XML config files are checked against RNG and XML Schema's.
329 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
330 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
331 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
332 explain record to YAZ CQL-to-PQF text config file.
336 Added 'timeout' setting for filter frontend_net which specifies the number
337 of seconds a session is idle before it is closed. Default timeout is
342 Database name in records returned set for virt_db/multi filters.
344 Filter session_shared now functional.
346 Log filter can be configured to write to a given file using 'filename'
347 element. Also information category can be specified with 'category'. If
348 filename is omitted, the log filter writes to stdout. See etc/config5.xml
353 Fixed compilation on Windows.
357 Added documentation for the hidenavailable option for the multi filter.
361 Fixed bug #573: Hide errors for individual servers. If the element
362 'hideunavailable' is given in the configuration, individual servers
363 being unavailable are hidden (unless all are unavailable).
365 Fixed bug #574: Database names are recognised case-sensitively.
367 Fixed bug #567: Fix up database name in Name-Plus-Record.
369 Fixed bug #568: Update win/makefile for VS 2005.
371 Fixed bug #569: Some options throws unknown exception.
375 More information about virtual hosts. The 'etc' directory is part of the
380 Build instructions for Windows. NMake makefile part of distribution tar.
386 Filters functional: auth_simple, backend_test, frontend_net, http_file,
387 log, multi, query_rewrite, template, virt_db, z3950_client.
389 Filters in development: session_shared.
391 Pseudo-filters: template, dl
