3 Change location of Metaproxy modules from libdir/metaproxy to
4 libdir/metaproxy4. Directory libdir/metaproxy is also owned by
5 libmetaproxy3 and, thus, should not be used by libmetaproxy4.
7 New facility to dump APDUs from zoom filter. Enabled by
8 <log apdu="true"/> in the zoom filter configuation.
10 zoom filter bug fix: SRU diagnostics received from backend was
11 not properly converted to Bib-1 diagnostics.
13 Package metaproxy depends on libmetaproxy4, same version.
17 zoom: fix a bug WRT passing authentication parameters to backends.
21 Fixes for windows Makefile.
25 Change major version of metaproxy library from 3 to 4. This in turn
26 makes new package names for Debian and RPM.
30 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2
33 zoom: configurable element sets for record transforms.
35 zoom: the target profile based transform is specified by element_transform
36 in element torus of of the ZOOM filter configuration ; default value
37 is "pz2". Target profile based retrieval is specified by element_raw
38 in configuration. It will perform same steps, but omit the XSL transform.
39 Default value is "raw".
41 zoom: element set is omitted if not set in profile. But only if pz2
42 transform is in effect. Previously the default element set was to "F".
44 zoom: For non-CF targets database arguments are parsed. User may supply
45 db,user=myuser&password=mypass for non-CF targets. These values override
46 what's given the authentication from the target profile.
48 session_shared: fix reference to freed memory. Would occur if a search
49 response had non-surrogate diagnostics.
53 Route may be given for each port in frontend_net.
57 Documentation for zoom filter. Local target profiles may be specified.
59 Fixes for zoom filter.
63 First version with zoom filter.
67 Filter z3950_client may be configured to always send a close APDU
68 to backend target when connection/session is closed. This will only
69 happen if close APDU is not already sent. Enabled by configuration
70 for z3950_client (force_close).
72 Filter virt_db and multi: relay close APDU.
74 Filter virt_db and multi: relay init size parameters
75 preferredMessageSize and maximumRecordSize.
77 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
81 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
83 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
84 as determined by configure.
86 RPM: Release includes 'indexdata' name. Use indexdata in release name so
87 this package can be distinguished from other vendors.
91 Fix filter multi: relay idAuthentication parameters.
95 Add metaproxy-config for returning compiler flags, libraries.
99 Fix --with-boost=PREFIX .
103 session_shared: fix use of maintenance thread.
105 Introduce 'start' method for filters and routers. It gets called after
106 configure and after fork, but before processing. This changes API -
107 from libmetaproxy2 to libmetaproxy3.
111 session_shared: ensure backend session is closed if init rejected
114 z3950_client: fix NULL ptr reference that could occur if two clients
115 connected concurrently and if max-sockets was in effect.
119 Fix bug 3497 - Metaproxy unstable while stopping.
121 Fix bug 3495 - SEGV in SRU filter.
125 Filter multi throws diagnostic 'Present Out of Range' when
126 appropriate - rather than returning 0 records.
128 Filter virt_db: fix bad result reuse. Could happen if a result
129 was overriden and a backend did not supported named result sets.
133 Filter log: category access logs diagnostics even if searchStatus
134 or presentStatus is 'success'.
138 The SRU to Z39.50 filter does repeated Z39.50 present requests
139 to fetch all records. Needed when a Z39.50 server returns partial
140 results (due to message size limits).
144 Metaproxy now kills all child processes that are spawned by
145 modules (in case of fork, exec).
149 Debian package now installs /etc/metaproxy/metaproxy.xml which
150 includes all XML files /etc/metaproxy/filters-enabled .
151 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
155 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
156 development package to facilitate 3rd party Metaproxy modules.
158 --- 1.0.23 2010/01/04
160 Filter virt_db: Close backend filter session when Init rejected is received
161 from it (in which case it's not really closed yet). This will ensure we don't
162 run out of resources such as FDs in this case.
164 sru_z3950 filter: Accept any database (including those not listed).
166 --- 1.0.22 2009/12/03
168 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
169 later which means YAZ 3.0.47 or later.
171 --- 1.0.20 2009/11/19
173 For filter virt_db, the database is a glob pattern and the virtual
174 database sections are consulted in the order given.
176 --- 1.0.19 2009/07/08
178 For filter multi, the target (for routing) may be given as a glob-pattern.
180 More documentation for filters virt_db and multi.
182 Update schema to allow for no database in sru_z3950 filter.
184 --- 1.0.18 2009/06/30
186 Added limit filter to put sleep (penalty) for heavy use.
188 Filter frontend_net may be configured to limit the number of new connections
189 from same IP to some value (connect-max).
191 Fixed the load_balance filter.
193 --- 1.0.17 2009/06/16
195 Fix path for metaproxy executable for Debian init.d script.
197 --- 1.0.16 2009/06/10
199 SRU to Z39.50 filter honors x-username and x-password. If only
200 x-username is given that translates to open authentication (Z39.50v2). If
201 both x-username and x-password is present that translates to idPass
202 authentication (Z39.50v3).
204 New facility to change current working directory (-w).
206 Update to upstream skeleton of init.d script. Should fix bug #2619.
208 Filter session_shared now caches records (used to only cache connections
211 Filter session_shared now invalidates a Z39.50 session if a server
212 returns -1 hits. This facility was also part of yazproxy and gets around
213 a bug in Voyager-based Z39.50 servers.
215 --- 1.0.15 2008/11/18
217 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
219 --- 1.0.14 2008/06/09
221 Fixed the value of SRU record schema in searchRetrieve response. It was set
222 to a fixed value of "dc" before.
224 Serialize identical SRU requests. This is useful if HTTP client software
225 fires identical requests against metaproxy.
227 Allow Z39.50 target to be specified for SRU requests by using SRU extra
228 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
229 avoid static configuration. This facility is handled by the sru_z3950 module
230 and the z3950_client module.
232 Allow maximum number of sockets to be used for a Z39.50 client by the
233 use of SRU extra parameter x-max-sockets. This facility is handled by the
234 sru_z3950 module and the z3950_client module.
236 --- 1.0.13.1 2008/02/29
238 Simplified check for Boost libraries.
240 --- 1.0.13 2008/02/29
242 First Debian package.
244 The sru_z9350 filter now recognizes SRU parameter z-target as being
245 a ZURL of the form host/database .
247 Mergetype may be specified for filter 'multi'.
249 --- 1.0.12 2007/09/19
251 Fixed problem in Makefile WRT library specifictions. This could produce
252 linker errors (when they should not happen).
254 Fixed bug #1341: MetaProxy returning different results. Problem was that
255 fix-up of record database did not normalize the database name.
257 Documentation updates for Windows compilation.
259 --- 1.0.11 2007/06/14
261 Fixed problem with logfile being truncated.
263 --- 1.0.10 2007/05/23
265 Fixed bug #1136: Access rights not enforced.
267 Extension for log module. The log category 'access' logs more details.
268 New category 'user-access' added which is simlar to 'access' but adds
269 the Z39.50 user as for all entries in a session.
273 Added support for configurable default/force target/vhost for module Z39.50
278 Implemented filter, session_shared, which optimizes usage of Z39.50
279 sessions and result sets.
281 New filter, record_transform, which converts MARC/XML records.
283 New filter, sru_z3950, which converts SRU to Z39.50 packages.
285 New filter, load_balance, in development.
287 New filter, zeerex_xplain.
289 XML framework for config files started.
291 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
292 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
293 XML config files are checked against RNG and XML Schema's.
295 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
296 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
297 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
298 explain record to YAZ CQL-to-PQF text config file.
302 Added 'timeout' setting for filter frontend_net which specifies the number
303 of seconds a session is idle before it is closed. Default timeout is
308 Database name in records returned set for virt_db/multi filters.
310 Filter session_shared now functional.
312 Log filter can be configured to write to a given file using 'filename'
313 element. Also information category can be specified with 'category'. If
314 filename is omitted, the log filter writes to stdout. See etc/config5.xml
319 Fixed compilation on Windows.
323 Added documentation for the hidenavailable option for the multi filter.
327 Fixed bug #573: Hide errors for individual servers. If the element
328 'hideunavailable' is given in the configuration, individual servers
329 being unavailable are hidden (unless all are unavailable).
331 Fixed bug #574: Database names are recognised case-sensitively.
333 Fixed bug #567: Fix up database name in Name-Plus-Record.
335 Fixed bug #568: Update win/makefile for VS 2005.
337 Fixed bug #569: Some options throws unknown exception.
341 More information about virtual hosts. The 'etc' directory is part of the
346 Build instructions for Windows. NMake makefile part of distribution tar.
352 Filters functional: auth_simple, backend_test, frontend_net, http_file,
353 log, multi, query_rewrite, template, virt_db, z3950_client.
355 Filters in development: session_shared.
