3 Fix bug in filter session_shared where sessions would not expire
4 properly (session ttl). This in turn could make the target close the
5 connection before expected and session_shared would return diagnostic
6 2: system temporarily available.
10 zoom: new target profile setting: sortmap_field. If sortmap_field is given
11 the field is mapped to the value for the sortmap. Values not matching
12 sortmap_field are passed verbatim.
14 zoom: new target profile setting: sortStrategy. One of: "z3950", "type7",
15 "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby
16 depending on whether RPN or CQL is actually sent to the target.
20 zoom: urlRecipe result is stored in <pz:metadata type="generated-url">.
22 zoom: For content proxy authentication is stored in param name
23 "auth", instead of "authentication".
27 zoom: relay schema in SRU mode. Previously recordSchema was not affected
32 zoom: new target profile element literalTransform that holds XSLT
33 (encoded as string) for target. Only if present and non-zero length it is
34 considered present. This takes precedence over transform.
36 Don't rely on trang anymore for Git checkout builds. Configuration in etc
37 will only be properly validated if trang is available. From now on only
38 relax NC files are bundled with the source dist.
40 Updates to check for Boost unit test (autoconf stuff). On MacOSX this
41 component was not detected when it should be.
45 z3950_client: mark non-surrogate diagnostics from backend.
47 zoom: a proxy may be specified for HTTP fetch of target profiles.
51 Honor piggyback. Makes some SRU targets behave that insist on
52 maximumRecords > 0, but also increases performance.
56 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
57 file was not update for libdir/metaproxy4 in version 1.3.2.
61 Change location of Metaproxy modules from libdir/metaproxy to
62 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
63 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
65 New facility to dump APDUs from zoom filter. Enabled by
66 <log apdu="true"/> in the zoom filter configuation.
68 zoom filter bug fix: SRU diagnostics received from backend was
69 not properly converted to Bib-1 diagnostics.
71 Package metaproxy depends on libmetaproxy4, same version.
75 zoom: fix a bug WRT passing authentication parameters to backends.
79 Fixes for windows Makefile.
83 Change major version of metaproxy library from 3 to 4. This in turn
84 makes new package names for Debian and RPM.
88 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
91 zoom: configurable element sets for record transforms.
93 zoom: the target profile based transform is specified by element_transform
94 in element torus of of the ZOOM filter configuration ; default value
95 is "pz2". Target profile based retrieval is specified by element_raw
96 in configuration. It will perform same steps, but omit the XSL transform.
97 Default value is "raw".
99 zoom: element set is omitted if not set in profile. But only if pz2
100 transform is in effect. Previously the default element set was to "F".
102 zoom: For non-CF targets database arguments are parsed. User may supply
103 db,user=myuser&password=mypass for non-CF targets. These values override
104 what's given the authentication from the target profile.
106 session_shared: fix reference to freed memory. Would occur if a search
107 response had non-surrogate diagnostics.
111 Route may be given for each port in frontend_net.
115 Documentation for zoom filter. Local target profiles may be specified.
117 Fixes for zoom filter.
121 First version with zoom filter.
125 Filter z3950_client may be configured to always send a close APDU
126 to backend target when connection/session is closed. This will only
127 happen if close APDU is not already sent. Enabled by configuration
128 for z3950_client (force_close).
130 Filter virt_db and multi: relay close APDU.
132 Filter virt_db and multi: relay init size parameters
133 preferredMessageSize and maximumRecordSize.
135 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
139 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
141 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
142 as determined by configure.
144 RPM: Release includes 'indexdata' name. Use indexdata in release name so
145 this package can be distinguished from other vendors.
149 Fix filter multi: relay idAuthentication parameters.
153 Add metaproxy-config for returning compiler flags, libraries.
157 Fix --with-boost=PREFIX .
161 session_shared: fix use of maintenance thread.
163 Introduce 'start' method for filters and routers. It gets called after
164 configure and after fork, but before processing. This changes API -
165 from libmetaproxy2 to libmetaproxy3.
169 session_shared: ensure backend session is closed if init rejected
172 z3950_client: fix NULL ptr reference that could occur if two clients
173 connected concurrently and if max-sockets was in effect.
177 Fix bug 3497 - Metaproxy unstable while stopping.
179 Fix bug 3495 - SEGV in SRU filter.
183 Filter multi throws diagnostic 'Present Out of Range' when
184 appropriate - rather than returning 0 records.
186 Filter virt_db: fix bad result reuse. Could happen if a result
187 was overriden and a backend did not supported named result sets.
191 Filter log: category access logs diagnostics even if searchStatus
192 or presentStatus is 'success'.
196 The SRU to Z39.50 filter does repeated Z39.50 present requests
197 to fetch all records. Needed when a Z39.50 server returns partial
198 results (due to message size limits).
202 Metaproxy now kills all child processes that are spawned by
203 modules (in case of fork, exec).
207 Debian package now installs /etc/metaproxy/metaproxy.xml which
208 includes all XML files /etc/metaproxy/filters-enabled .
209 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
213 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
214 development package to facilitate 3rd party Metaproxy modules.
216 --- 1.0.23 2010/01/04
218 Filter virt_db: Close backend filter session when Init rejected is received
219 from it (in which case it's not really closed yet). This will ensure we don't
220 run out of resources such as FDs in this case.
222 sru_z3950 filter: Accept any database (including those not listed).
224 --- 1.0.22 2009/12/03
226 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
227 later which means YAZ 3.0.47 or later.
229 --- 1.0.20 2009/11/19
231 For filter virt_db, the database is a glob pattern and the virtual
232 database sections are consulted in the order given.
234 --- 1.0.19 2009/07/08
236 For filter multi, the target (for routing) may be given as a glob-pattern.
238 More documentation for filters virt_db and multi.
240 Update schema to allow for no database in sru_z3950 filter.
242 --- 1.0.18 2009/06/30
244 Added limit filter to put sleep (penalty) for heavy use.
246 Filter frontend_net may be configured to limit the number of new connections
247 from same IP to some value (connect-max).
249 Fixed the load_balance filter.
251 --- 1.0.17 2009/06/16
253 Fix path for metaproxy executable for Debian init.d script.
255 --- 1.0.16 2009/06/10
257 SRU to Z39.50 filter honors x-username and x-password. If only
258 x-username is given that translates to open authentication (Z39.50v2). If
259 both x-username and x-password is present that translates to idPass
260 authentication (Z39.50v3).
262 New facility to change current working directory (-w).
264 Update to upstream skeleton of init.d script. Should fix bug #2619.
266 Filter session_shared now caches records (used to only cache connections
269 Filter session_shared now invalidates a Z39.50 session if a server
270 returns -1 hits. This facility was also part of yazproxy and gets around
271 a bug in Voyager-based Z39.50 servers.
273 --- 1.0.15 2008/11/18
275 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
277 --- 1.0.14 2008/06/09
279 Fixed the value of SRU record schema in searchRetrieve response. It was set
280 to a fixed value of "dc" before.
282 Serialize identical SRU requests. This is useful if HTTP client software
283 fires identical requests against metaproxy.
285 Allow Z39.50 target to be specified for SRU requests by using SRU extra
286 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
287 avoid static configuration. This facility is handled by the sru_z3950 module
288 and the z3950_client module.
290 Allow maximum number of sockets to be used for a Z39.50 client by the
291 use of SRU extra parameter x-max-sockets. This facility is handled by the
292 sru_z3950 module and the z3950_client module.
294 --- 1.0.13.1 2008/02/29
296 Simplified check for Boost libraries.
298 --- 1.0.13 2008/02/29
300 First Debian package.
302 The sru_z9350 filter now recognizes SRU parameter z-target as being
303 a ZURL of the form host/database .
305 Mergetype may be specified for filter 'multi'.
307 --- 1.0.12 2007/09/19
309 Fixed problem in Makefile WRT library specifictions. This could produce
310 linker errors (when they should not happen).
312 Fixed bug #1341: MetaProxy returning different results. Problem was that
313 fix-up of record database did not normalize the database name.
315 Documentation updates for Windows compilation.
317 --- 1.0.11 2007/06/14
319 Fixed problem with logfile being truncated.
321 --- 1.0.10 2007/05/23
323 Fixed bug #1136: Access rights not enforced.
325 Extension for log module. The log category 'access' logs more details.
326 New category 'user-access' added which is simlar to 'access' but adds
327 the Z39.50 user as for all entries in a session.
331 Added support for configurable default/force target/vhost for module Z39.50
336 Implemented filter, session_shared, which optimizes usage of Z39.50
337 sessions and result sets.
339 New filter, record_transform, which converts MARC/XML records.
341 New filter, sru_z3950, which converts SRU to Z39.50 packages.
343 New filter, load_balance, in development.
345 New filter, zeerex_xplain.
347 XML framework for config files started.
349 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
350 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
351 XML config files are checked against RNG and XML Schema's.
353 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
354 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
355 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
356 explain record to YAZ CQL-to-PQF text config file.
360 Added 'timeout' setting for filter frontend_net which specifies the number
361 of seconds a session is idle before it is closed. Default timeout is
366 Database name in records returned set for virt_db/multi filters.
368 Filter session_shared now functional.
370 Log filter can be configured to write to a given file using 'filename'
371 element. Also information category can be specified with 'category'. If
372 filename is omitted, the log filter writes to stdout. See etc/config5.xml
377 Fixed compilation on Windows.
381 Added documentation for the hidenavailable option for the multi filter.
385 Fixed bug #573: Hide errors for individual servers. If the element
386 'hideunavailable' is given in the configuration, individual servers
387 being unavailable are hidden (unless all are unavailable).
389 Fixed bug #574: Database names are recognised case-sensitively.
391 Fixed bug #567: Fix up database name in Name-Plus-Record.
393 Fixed bug #568: Update win/makefile for VS 2005.
395 Fixed bug #569: Some options throws unknown exception.
399 More information about virtual hosts. The 'etc' directory is part of the
404 Build instructions for Windows. NMake makefile part of distribution tar.
410 Filters functional: auth_simple, backend_test, frontend_net, http_file,
411 log, multi, query_rewrite, template, virt_db, z3950_client.
413 Filters in development: session_shared.
