3 Change target profile parameter CfSubDb to CfSubDB.
7 zoom: bug fix: realm was relayed to CF targets by mistake (realm only
8 makes sense to the zoom module itself).
12 zoom: realm may be given as part of database.
16 Fix Origin class assigment method; was removd by mistake in 1.3.12.
20 zoom: database args x-name=value are passed through to backend database.
22 SRU filter: user may specify session ID that is passed to log entries
23 that follows. It is specified by using x-session-id in the SRU arguments.
25 zoom: fix null pointer reference which would occur for bad url parameter
26 inside "torus" or if url was not given.
29 Fix bug in filter session_shared where sessions would not expire
30 properly (session ttl). This in turn could make the target close the
31 connection before expected and session_shared would return diagnostic
32 2: system temporarily available.
36 zoom: new target profile setting: sortmap_field. If sortmap_field is given
37 the field is mapped to the value for the sortmap. Values not matching
38 sortmap_field are passed verbatim.
40 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
41 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
42 depending on whether RPN or CQL is actually sent to the target.
46 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
48 zoom: For content proxy authentication is stored in param name
49 "auth", instead of "authentication".
53 zoom: relay schema in SRU mode. Previously recordSchema was not affected
58 zoom: new target profile element literalTransform that holds XSLT
59 (encoded as string) for target. Only if present and non-zero length it is
60 considered present. This takes precedence over transform.
62 Don't rely on trang anymore for Git checkout builds. Configuration in etc
63 will only be properly validated if trang is available. From now on only
64 relax NC files are bundled with the source dist.
66 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
67 component was not detected when it should be.
71 z3950_client: mark non-surrogate diagnostics from backend.
73 zoom: a proxy may be specified for HTTP fetch of target profiles.
77 Honor piggyback. Makes some SRU targets behave that insist on
78 maximumRecords > 0, but also increases performance.
82 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
83 file was not update for libdir/metaproxy4 in version 1.3.2.
87 Change location of Metaproxy modules from libdir/metaproxy to
88 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
89 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
91 New facility to dump APDUs from zoom filter. Enabled by
92 <log apdu="true"/> in the zoom filter configuation.
94 zoom filter bug fix: SRU diagnostics received from backend was
95 not properly converted to Bib-1 diagnostics.
97 Package metaproxy depends on libmetaproxy4, same version.
101 zoom: fix a bug WRT passing authentication parameters to backends.
105 Fixes for windows Makefile.
107 --- 1.2.10 2011/07/25
109 Change major version of metaproxy library from 3 to 4. This in turn
110 makes new package names for Debian and RPM.
114 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
117 zoom: configurable element sets for record transforms.
119 zoom: the target profile based transform is specified by element_transform
120 in element torus of of the ZOOM filter configuration ; default value
121 is "pz2". Target profile based retrieval is specified by element_raw
122 in configuration. It will perform same steps, but omit the XSL transform.
123 Default value is "raw".
125 zoom: element set is omitted if not set in profile. But only if pz2
126 transform is in effect. Previously the default element set was to "F".
128 zoom: For non-CF targets database arguments are parsed. User may supply
129 db,user=myuser&password=mypass for non-CF targets. These values override
130 what's given the authentication from the target profile.
132 session_shared: fix reference to freed memory. Would occur if a search
133 response had non-surrogate diagnostics.
137 Route may be given for each port in frontend_net.
141 Documentation for zoom filter. Local target profiles may be specified.
143 Fixes for zoom filter.
147 First version with zoom filter.
151 Filter z3950_client may be configured to always send a close APDU
152 to backend target when connection/session is closed. This will only
153 happen if close APDU is not already sent. Enabled by configuration
154 for z3950_client (force_close).
156 Filter virt_db and multi: relay close APDU.
158 Filter virt_db and multi: relay init size parameters
159 preferredMessageSize and maximumRecordSize.
161 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
165 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
167 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
168 as determined by configure.
170 RPM: Release includes 'indexdata' name. Use indexdata in release name so
171 this package can be distinguished from other vendors.
175 Fix filter multi: relay idAuthentication parameters.
179 Add metaproxy-config for returning compiler flags, libraries.
183 Fix --with-boost=PREFIX .
187 session_shared: fix use of maintenance thread.
189 Introduce 'start' method for filters and routers. It gets called after
190 configure and after fork, but before processing. This changes API -
191 from libmetaproxy2 to libmetaproxy3.
195 session_shared: ensure backend session is closed if init rejected
198 z3950_client: fix NULL ptr reference that could occur if two clients
199 connected concurrently and if max-sockets was in effect.
203 Fix bug 3497 - Metaproxy unstable while stopping.
205 Fix bug 3495 - SEGV in SRU filter.
209 Filter multi throws diagnostic 'Present Out of Range' when
210 appropriate - rather than returning 0 records.
212 Filter virt_db: fix bad result reuse. Could happen if a result
213 was overriden and a backend did not supported named result sets.
217 Filter log: category access logs diagnostics even if searchStatus
218 or presentStatus is 'success'.
222 The SRU to Z39.50 filter does repeated Z39.50 present requests
223 to fetch all records. Needed when a Z39.50 server returns partial
224 results (due to message size limits).
228 Metaproxy now kills all child processes that are spawned by
229 modules (in case of fork, exec).
233 Debian package now installs /etc/metaproxy/metaproxy.xml which
234 includes all XML files /etc/metaproxy/filters-enabled .
235 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
239 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
240 development package to facilitate 3rd party Metaproxy modules.
242 --- 1.0.23 2010/01/04
244 Filter virt_db: Close backend filter session when Init rejected is received
245 from it (in which case it's not really closed yet). This will ensure we don't
246 run out of resources such as FDs in this case.
248 sru_z3950 filter: Accept any database (including those not listed).
250 --- 1.0.22 2009/12/03
252 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
253 later which means YAZ 3.0.47 or later.
255 --- 1.0.20 2009/11/19
257 For filter virt_db, the database is a glob pattern and the virtual
258 database sections are consulted in the order given.
260 --- 1.0.19 2009/07/08
262 For filter multi, the target (for routing) may be given as a glob-pattern.
264 More documentation for filters virt_db and multi.
266 Update schema to allow for no database in sru_z3950 filter.
268 --- 1.0.18 2009/06/30
270 Added limit filter to put sleep (penalty) for heavy use.
272 Filter frontend_net may be configured to limit the number of new connections
273 from same IP to some value (connect-max).
275 Fixed the load_balance filter.
277 --- 1.0.17 2009/06/16
279 Fix path for metaproxy executable for Debian init.d script.
281 --- 1.0.16 2009/06/10
283 SRU to Z39.50 filter honors x-username and x-password. If only
284 x-username is given that translates to open authentication (Z39.50v2). If
285 both x-username and x-password is present that translates to idPass
286 authentication (Z39.50v3).
288 New facility to change current working directory (-w).
290 Update to upstream skeleton of init.d script. Should fix bug #2619.
292 Filter session_shared now caches records (used to only cache connections
295 Filter session_shared now invalidates a Z39.50 session if a server
296 returns -1 hits. This facility was also part of yazproxy and gets around
297 a bug in Voyager-based Z39.50 servers.
299 --- 1.0.15 2008/11/18
301 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
303 --- 1.0.14 2008/06/09
305 Fixed the value of SRU record schema in searchRetrieve response. It was set
306 to a fixed value of "dc" before.
308 Serialize identical SRU requests. This is useful if HTTP client software
309 fires identical requests against metaproxy.
311 Allow Z39.50 target to be specified for SRU requests by using SRU extra
312 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
313 avoid static configuration. This facility is handled by the sru_z3950 module
314 and the z3950_client module.
316 Allow maximum number of sockets to be used for a Z39.50 client by the
317 use of SRU extra parameter x-max-sockets. This facility is handled by the
318 sru_z3950 module and the z3950_client module.
320 --- 1.0.13.1 2008/02/29
322 Simplified check for Boost libraries.
324 --- 1.0.13 2008/02/29
326 First Debian package.
328 The sru_z9350 filter now recognizes SRU parameter z-target as being
329 a ZURL of the form host/database .
331 Mergetype may be specified for filter 'multi'.
333 --- 1.0.12 2007/09/19
335 Fixed problem in Makefile WRT library specifictions. This could produce
336 linker errors (when they should not happen).
338 Fixed bug #1341: MetaProxy returning different results. Problem was that
339 fix-up of record database did not normalize the database name.
341 Documentation updates for Windows compilation.
343 --- 1.0.11 2007/06/14
345 Fixed problem with logfile being truncated.
347 --- 1.0.10 2007/05/23
349 Fixed bug #1136: Access rights not enforced.
351 Extension for log module. The log category 'access' logs more details.
352 New category 'user-access' added which is simlar to 'access' but adds
353 the Z39.50 user as for all entries in a session.
357 Added support for configurable default/force target/vhost for module Z39.50
362 Implemented filter, session_shared, which optimizes usage of Z39.50
363 sessions and result sets.
365 New filter, record_transform, which converts MARC/XML records.
367 New filter, sru_z3950, which converts SRU to Z39.50 packages.
369 New filter, load_balance, in development.
371 New filter, zeerex_xplain.
373 XML framework for config files started.
375 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
376 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
377 XML config files are checked against RNG and XML Schema's.
379 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
380 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
381 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
382 explain record to YAZ CQL-to-PQF text config file.
386 Added 'timeout' setting for filter frontend_net which specifies the number
387 of seconds a session is idle before it is closed. Default timeout is
392 Database name in records returned set for virt_db/multi filters.
394 Filter session_shared now functional.
396 Log filter can be configured to write to a given file using 'filename'
397 element. Also information category can be specified with 'category'. If
398 filename is omitted, the log filter writes to stdout. See etc/config5.xml
403 Fixed compilation on Windows.
407 Added documentation for the hidenavailable option for the multi filter.
411 Fixed bug #573: Hide errors for individual servers. If the element
412 'hideunavailable' is given in the configuration, individual servers
413 being unavailable are hidden (unless all are unavailable).
415 Fixed bug #574: Database names are recognised case-sensitively.
417 Fixed bug #567: Fix up database name in Name-Plus-Record.
419 Fixed bug #568: Update win/makefile for VS 2005.
421 Fixed bug #569: Some options throws unknown exception.
425 More information about virtual hosts. The 'etc' directory is part of the
430 Build instructions for Windows. NMake makefile part of distribution tar.
436 Filters functional: auth_simple, backend_test, frontend_net, http_file,
437 log, multi, query_rewrite, template, virt_db, z3950_client.
439 Filters in development: session_shared.
