3 z3950_client: mark non-surrogate diagnostics from backend.
5 zoom: a proxy may be specified for HTTP fetch of target profiles.
9 Honor piggyback. Makes some SRU targets behave that insist on
10 maximumRecords > 0, but also increases performance.
14 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The
15 file was not update for libdir/metaproxy4 in version 1.3.2.
19 Change location of Metaproxy modules from libdir/metaproxy to
20 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
21 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
23 New facility to dump APDUs from zoom filter. Enabled by
24 <log apdu="true"/> in the zoom filter configuation.
26 zoom filter bug fix: SRU diagnostics received from backend was
27 not properly converted to Bib-1 diagnostics.
29 Package metaproxy depends on libmetaproxy4, same version.
33 zoom: fix a bug WRT passing authentication parameters to backends.
37 Fixes for windows Makefile.
41 Change major version of metaproxy library from 3 to 4. This in turn
42 makes new package names for Debian and RPM.
46 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
49 zoom: configurable element sets for record transforms.
51 zoom: the target profile based transform is specified by element_transform
52 in element torus of of the ZOOM filter configuration ; default value
53 is "pz2". Target profile based retrieval is specified by element_raw
54 in configuration. It will perform same steps, but omit the XSL transform.
55 Default value is "raw".
57 zoom: element set is omitted if not set in profile. But only if pz2
58 transform is in effect. Previously the default element set was to "F".
60 zoom: For non-CF targets database arguments are parsed. User may supply
61 db,user=myuser&password=mypass for non-CF targets. These values override
62 what's given the authentication from the target profile.
64 session_shared: fix reference to freed memory. Would occur if a search
65 response had non-surrogate diagnostics.
69 Route may be given for each port in frontend_net.
73 Documentation for zoom filter. Local target profiles may be specified.
75 Fixes for zoom filter.
79 First version with zoom filter.
83 Filter z3950_client may be configured to always send a close APDU
84 to backend target when connection/session is closed. This will only
85 happen if close APDU is not already sent. Enabled by configuration
86 for z3950_client (force_close).
88 Filter virt_db and multi: relay close APDU.
90 Filter virt_db and multi: relay init size parameters
91 preferredMessageSize and maximumRecordSize.
93 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
97 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
99 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
100 as determined by configure.
102 RPM: Release includes 'indexdata' name. Use indexdata in release name so
103 this package can be distinguished from other vendors.
107 Fix filter multi: relay idAuthentication parameters.
111 Add metaproxy-config for returning compiler flags, libraries.
115 Fix --with-boost=PREFIX .
119 session_shared: fix use of maintenance thread.
121 Introduce 'start' method for filters and routers. It gets called after
122 configure and after fork, but before processing. This changes API -
123 from libmetaproxy2 to libmetaproxy3.
127 session_shared: ensure backend session is closed if init rejected
130 z3950_client: fix NULL ptr reference that could occur if two clients
131 connected concurrently and if max-sockets was in effect.
135 Fix bug 3497 - Metaproxy unstable while stopping.
137 Fix bug 3495 - SEGV in SRU filter.
141 Filter multi throws diagnostic 'Present Out of Range' when
142 appropriate - rather than returning 0 records.
144 Filter virt_db: fix bad result reuse. Could happen if a result
145 was overriden and a backend did not supported named result sets.
149 Filter log: category access logs diagnostics even if searchStatus
150 or presentStatus is 'success'.
154 The SRU to Z39.50 filter does repeated Z39.50 present requests
155 to fetch all records. Needed when a Z39.50 server returns partial
156 results (due to message size limits).
160 Metaproxy now kills all child processes that are spawned by
161 modules (in case of fork, exec).
165 Debian package now installs /etc/metaproxy/metaproxy.xml which
166 includes all XML files /etc/metaproxy/filters-enabled .
167 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
171 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
172 development package to facilitate 3rd party Metaproxy modules.
174 --- 1.0.23 2010/01/04
176 Filter virt_db: Close backend filter session when Init rejected is received
177 from it (in which case it's not really closed yet). This will ensure we don't
178 run out of resources such as FDs in this case.
180 sru_z3950 filter: Accept any database (including those not listed).
182 --- 1.0.22 2009/12/03
184 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
185 later which means YAZ 3.0.47 or later.
187 --- 1.0.20 2009/11/19
189 For filter virt_db, the database is a glob pattern and the virtual
190 database sections are consulted in the order given.
192 --- 1.0.19 2009/07/08
194 For filter multi, the target (for routing) may be given as a glob-pattern.
196 More documentation for filters virt_db and multi.
198 Update schema to allow for no database in sru_z3950 filter.
200 --- 1.0.18 2009/06/30
202 Added limit filter to put sleep (penalty) for heavy use.
204 Filter frontend_net may be configured to limit the number of new connections
205 from same IP to some value (connect-max).
207 Fixed the load_balance filter.
209 --- 1.0.17 2009/06/16
211 Fix path for metaproxy executable for Debian init.d script.
213 --- 1.0.16 2009/06/10
215 SRU to Z39.50 filter honors x-username and x-password. If only
216 x-username is given that translates to open authentication (Z39.50v2). If
217 both x-username and x-password is present that translates to idPass
218 authentication (Z39.50v3).
220 New facility to change current working directory (-w).
222 Update to upstream skeleton of init.d script. Should fix bug #2619.
224 Filter session_shared now caches records (used to only cache connections
227 Filter session_shared now invalidates a Z39.50 session if a server
228 returns -1 hits. This facility was also part of yazproxy and gets around
229 a bug in Voyager-based Z39.50 servers.
231 --- 1.0.15 2008/11/18
233 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
235 --- 1.0.14 2008/06/09
237 Fixed the value of SRU record schema in searchRetrieve response. It was set
238 to a fixed value of "dc" before.
240 Serialize identical SRU requests. This is useful if HTTP client software
241 fires identical requests against metaproxy.
243 Allow Z39.50 target to be specified for SRU requests by using SRU extra
244 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
245 avoid static configuration. This facility is handled by the sru_z3950 module
246 and the z3950_client module.
248 Allow maximum number of sockets to be used for a Z39.50 client by the
249 use of SRU extra parameter x-max-sockets. This facility is handled by the
250 sru_z3950 module and the z3950_client module.
252 --- 1.0.13.1 2008/02/29
254 Simplified check for Boost libraries.
256 --- 1.0.13 2008/02/29
258 First Debian package.
260 The sru_z9350 filter now recognizes SRU parameter z-target as being
261 a ZURL of the form host/database .
263 Mergetype may be specified for filter 'multi'.
265 --- 1.0.12 2007/09/19
267 Fixed problem in Makefile WRT library specifictions. This could produce
268 linker errors (when they should not happen).
270 Fixed bug #1341: MetaProxy returning different results. Problem was that
271 fix-up of record database did not normalize the database name.
273 Documentation updates for Windows compilation.
275 --- 1.0.11 2007/06/14
277 Fixed problem with logfile being truncated.
279 --- 1.0.10 2007/05/23
281 Fixed bug #1136: Access rights not enforced.
283 Extension for log module. The log category 'access' logs more details.
284 New category 'user-access' added which is simlar to 'access' but adds
285 the Z39.50 user as for all entries in a session.
289 Added support for configurable default/force target/vhost for module Z39.50
294 Implemented filter, session_shared, which optimizes usage of Z39.50
295 sessions and result sets.
297 New filter, record_transform, which converts MARC/XML records.
299 New filter, sru_z3950, which converts SRU to Z39.50 packages.
301 New filter, load_balance, in development.
303 New filter, zeerex_xplain.
305 XML framework for config files started.
307 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
308 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
309 XML config files are checked against RNG and XML Schema's.
311 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
312 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
313 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
314 explain record to YAZ CQL-to-PQF text config file.
318 Added 'timeout' setting for filter frontend_net which specifies the number
319 of seconds a session is idle before it is closed. Default timeout is
324 Database name in records returned set for virt_db/multi filters.
326 Filter session_shared now functional.
328 Log filter can be configured to write to a given file using 'filename'
329 element. Also information category can be specified with 'category'. If
330 filename is omitted, the log filter writes to stdout. See etc/config5.xml
335 Fixed compilation on Windows.
339 Added documentation for the hidenavailable option for the multi filter.
343 Fixed bug #573: Hide errors for individual servers. If the element
344 'hideunavailable' is given in the configuration, individual servers
345 being unavailable are hidden (unless all are unavailable).
347 Fixed bug #574: Database names are recognised case-sensitively.
349 Fixed bug #567: Fix up database name in Name-Plus-Record.
351 Fixed bug #568: Update win/makefile for VS 2005.
353 Fixed bug #569: Some options throws unknown exception.
357 More information about virtual hosts. The 'etc' directory is part of the
362 Build instructions for Windows. NMake makefile part of distribution tar.
368 Filters functional: auth_simple, backend_test, frontend_net, http_file,
369 log, multi, query_rewrite, template, virt_db, z3950_client.
371 Filters in development: session_shared.
