1 zoom: new target profile element literalTransform that holds XSLT
2 (encoded as string) for target. Only if present and non-zero length it is
3 considered present. This takes precedence over transform.
7 z3950_client: mark non-surrogate diagnostics from backend.
9 zoom: a proxy may be specified for HTTP fetch of target profiles.
13 Honor piggyback. Makes some SRU targets behave that insist on
14 maximumRecords > 0, but also increases performance.
18 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
19 file was not update for libdir/metaproxy4 in version 1.3.2.
23 Change location of Metaproxy modules from libdir/metaproxy to
24 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
25 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
27 New facility to dump APDUs from zoom filter. Enabled by
28 <log apdu="true"/> in the zoom filter configuation.
30 zoom filter bug fix: SRU diagnostics received from backend was
31 not properly converted to Bib-1 diagnostics.
33 Package metaproxy depends on libmetaproxy4, same version.
37 zoom: fix a bug WRT passing authentication parameters to backends.
41 Fixes for windows Makefile.
45 Change major version of metaproxy library from 3 to 4. This in turn
46 makes new package names for Debian and RPM.
50 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
53 zoom: configurable element sets for record transforms.
55 zoom: the target profile based transform is specified by element_transform
56 in element torus of of the ZOOM filter configuration ; default value
57 is "pz2". Target profile based retrieval is specified by element_raw
58 in configuration. It will perform same steps, but omit the XSL transform.
59 Default value is "raw".
61 zoom: element set is omitted if not set in profile. But only if pz2
62 transform is in effect. Previously the default element set was to "F".
64 zoom: For non-CF targets database arguments are parsed. User may supply
65 db,user=myuser&password=mypass for non-CF targets. These values override
66 what's given the authentication from the target profile.
68 session_shared: fix reference to freed memory. Would occur if a search
69 response had non-surrogate diagnostics.
73 Route may be given for each port in frontend_net.
77 Documentation for zoom filter. Local target profiles may be specified.
79 Fixes for zoom filter.
83 First version with zoom filter.
87 Filter z3950_client may be configured to always send a close APDU
88 to backend target when connection/session is closed. This will only
89 happen if close APDU is not already sent. Enabled by configuration
90 for z3950_client (force_close).
92 Filter virt_db and multi: relay close APDU.
94 Filter virt_db and multi: relay init size parameters
95 preferredMessageSize and maximumRecordSize.
97 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
101 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
103 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
104 as determined by configure.
106 RPM: Release includes 'indexdata' name. Use indexdata in release name so
107 this package can be distinguished from other vendors.
111 Fix filter multi: relay idAuthentication parameters.
115 Add metaproxy-config for returning compiler flags, libraries.
119 Fix --with-boost=PREFIX .
123 session_shared: fix use of maintenance thread.
125 Introduce 'start' method for filters and routers. It gets called after
126 configure and after fork, but before processing. This changes API -
127 from libmetaproxy2 to libmetaproxy3.
131 session_shared: ensure backend session is closed if init rejected
134 z3950_client: fix NULL ptr reference that could occur if two clients
135 connected concurrently and if max-sockets was in effect.
139 Fix bug 3497 - Metaproxy unstable while stopping.
141 Fix bug 3495 - SEGV in SRU filter.
145 Filter multi throws diagnostic 'Present Out of Range' when
146 appropriate - rather than returning 0 records.
148 Filter virt_db: fix bad result reuse. Could happen if a result
149 was overriden and a backend did not supported named result sets.
153 Filter log: category access logs diagnostics even if searchStatus
154 or presentStatus is 'success'.
158 The SRU to Z39.50 filter does repeated Z39.50 present requests
159 to fetch all records. Needed when a Z39.50 server returns partial
160 results (due to message size limits).
164 Metaproxy now kills all child processes that are spawned by
165 modules (in case of fork, exec).
169 Debian package now installs /etc/metaproxy/metaproxy.xml which
170 includes all XML files /etc/metaproxy/filters-enabled .
171 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
175 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
176 development package to facilitate 3rd party Metaproxy modules.
178 --- 1.0.23 2010/01/04
180 Filter virt_db: Close backend filter session when Init rejected is received
181 from it (in which case it's not really closed yet). This will ensure we don't
182 run out of resources such as FDs in this case.
184 sru_z3950 filter: Accept any database (including those not listed).
186 --- 1.0.22 2009/12/03
188 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
189 later which means YAZ 3.0.47 or later.
191 --- 1.0.20 2009/11/19
193 For filter virt_db, the database is a glob pattern and the virtual
194 database sections are consulted in the order given.
196 --- 1.0.19 2009/07/08
198 For filter multi, the target (for routing) may be given as a glob-pattern.
200 More documentation for filters virt_db and multi.
202 Update schema to allow for no database in sru_z3950 filter.
204 --- 1.0.18 2009/06/30
206 Added limit filter to put sleep (penalty) for heavy use.
208 Filter frontend_net may be configured to limit the number of new connections
209 from same IP to some value (connect-max).
211 Fixed the load_balance filter.
213 --- 1.0.17 2009/06/16
215 Fix path for metaproxy executable for Debian init.d script.
217 --- 1.0.16 2009/06/10
219 SRU to Z39.50 filter honors x-username and x-password. If only
220 x-username is given that translates to open authentication (Z39.50v2). If
221 both x-username and x-password is present that translates to idPass
222 authentication (Z39.50v3).
224 New facility to change current working directory (-w).
226 Update to upstream skeleton of init.d script. Should fix bug #2619.
228 Filter session_shared now caches records (used to only cache connections
231 Filter session_shared now invalidates a Z39.50 session if a server
232 returns -1 hits. This facility was also part of yazproxy and gets around
233 a bug in Voyager-based Z39.50 servers.
235 --- 1.0.15 2008/11/18
237 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
239 --- 1.0.14 2008/06/09
241 Fixed the value of SRU record schema in searchRetrieve response. It was set
242 to a fixed value of "dc" before.
244 Serialize identical SRU requests. This is useful if HTTP client software
245 fires identical requests against metaproxy.
247 Allow Z39.50 target to be specified for SRU requests by using SRU extra
248 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
249 avoid static configuration. This facility is handled by the sru_z3950 module
250 and the z3950_client module.
252 Allow maximum number of sockets to be used for a Z39.50 client by the
253 use of SRU extra parameter x-max-sockets. This facility is handled by the
254 sru_z3950 module and the z3950_client module.
256 --- 1.0.13.1 2008/02/29
258 Simplified check for Boost libraries.
260 --- 1.0.13 2008/02/29
262 First Debian package.
264 The sru_z9350 filter now recognizes SRU parameter z-target as being
265 a ZURL of the form host/database .
267 Mergetype may be specified for filter 'multi'.
269 --- 1.0.12 2007/09/19
271 Fixed problem in Makefile WRT library specifictions. This could produce
272 linker errors (when they should not happen).
274 Fixed bug #1341: MetaProxy returning different results. Problem was that
275 fix-up of record database did not normalize the database name.
277 Documentation updates for Windows compilation.
279 --- 1.0.11 2007/06/14
281 Fixed problem with logfile being truncated.
283 --- 1.0.10 2007/05/23
285 Fixed bug #1136: Access rights not enforced.
287 Extension for log module. The log category 'access' logs more details.
288 New category 'user-access' added which is simlar to 'access' but adds
289 the Z39.50 user as for all entries in a session.
293 Added support for configurable default/force target/vhost for module Z39.50
298 Implemented filter, session_shared, which optimizes usage of Z39.50
299 sessions and result sets.
301 New filter, record_transform, which converts MARC/XML records.
303 New filter, sru_z3950, which converts SRU to Z39.50 packages.
305 New filter, load_balance, in development.
307 New filter, zeerex_xplain.
309 XML framework for config files started.
311 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
312 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
313 XML config files are checked against RNG and XML Schema's.
315 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
316 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
317 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
318 explain record to YAZ CQL-to-PQF text config file.
322 Added 'timeout' setting for filter frontend_net which specifies the number
323 of seconds a session is idle before it is closed. Default timeout is
328 Database name in records returned set for virt_db/multi filters.
330 Filter session_shared now functional.
332 Log filter can be configured to write to a given file using 'filename'
333 element. Also information category can be specified with 'category'. If
334 filename is omitted, the log filter writes to stdout. See etc/config5.xml
339 Fixed compilation on Windows.
343 Added documentation for the hidenavailable option for the multi filter.
347 Fixed bug #573: Hide errors for individual servers. If the element
348 'hideunavailable' is given in the configuration, individual servers
349 being unavailable are hidden (unless all are unavailable).
351 Fixed bug #574: Database names are recognised case-sensitively.
353 Fixed bug #567: Fix up database name in Name-Plus-Record.
355 Fixed bug #568: Update win/makefile for VS 2005.
357 Fixed bug #569: Some options throws unknown exception.
361 More information about virtual hosts. The 'etc' directory is part of the
366 Build instructions for Windows. NMake makefile part of distribution tar.
372 Filters functional: auth_simple, backend_test, frontend_net, http_file,
373 log, multi, query_rewrite, template, virt_db, z3950_client.
375 Filters in development: session_shared.
