3 Filter z3950_client may be configured to always send a close APDU
4 to backend target when connection/session is closed. This will only
5 happen if close APDU is not already sent. Enabled by configuration
6 for z3950_client (force_close).
8 Filter virt_db and multi relays close APDU.
10 Filter virt_db and multi: relay init size parameters
11 preferredMessageSize and maximumRecordSize.
13 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
17 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
19 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
20 as determined by configure.
22 RPM: Release includes 'indexdata' name. Use indexdata in release name so
23 this package can be distinguished from other vendors.
27 Fix filter multi: relay idAuthentication parameters.
31 Add metaproxy-config for returning compiler flags, libraries.
35 Fix --with-boost=PREFIX .
39 session_shared: fix use of maintenance thread.
41 Introduce 'start' method for filters and routers. It gets called after
42 configure and after fork, but before processing. This changes API -
43 from libmetaproxy2 to libmetaproxy3.
47 session_shared: ensure backend session is closed if init rejected
50 z3950_client: fix NULL ptr reference that could occur if two clients
51 connected concurrently and if max-sockets was in effect.
55 Fix bug 3497 - Metaproxy unstable while stopping.
57 Fix bug 3495 - SEGV in SRU filter.
61 Filter multi throws diagnostic 'Present Out of Range' when
62 appropriate - rather than returning 0 records.
64 Filter virt_db: fix bad result reuse. Could happen if a result
65 was overriden and a backend did not supported named result sets.
69 Filter log: category access logs diagnostics even if searchStatus
70 or presentStatus is 'success'.
74 The SRU to Z39.50 filter does repeated Z39.50 present requests
75 to fetch all records. Needed when a Z39.50 server returns partial
76 results (due to message size limits).
80 Metaproxy now kills all child processes that are spawned by
81 modules (in case of fork, exec).
85 Debian package now installs /etc/metaproxy/metaproxy.xml which
86 includes all XML files /etc/metaproxy/filters-enabled .
87 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
91 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
92 development package to facilitate 3rd party Metaproxy modules.
96 Filter virt_db: Close backend filter session when Init rejected is received
97 from it (in which case it's not really closed yet). This will ensure we don't
98 run out of resources such as FDs in this case.
100 sru_z3950 filter: Accept any database (including those not listed).
102 --- 1.0.22 2009/12/03
104 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
105 later which means YAZ 3.0.47 or later.
107 --- 1.0.20 2009/11/19
109 For filter virt_db, the database is a glob pattern and the virtual
110 database sections are consulted in the order given.
112 --- 1.0.19 2009/07/08
114 For filter multi, the target (for routing) may be given as a glob-pattern.
116 More documentation for filters virt_db and multi.
118 Update schema to allow for no database in sru_z3950 filter.
120 --- 1.0.18 2009/06/30
122 Added limit filter to put sleep (penalty) for heavy use.
124 Filter frontend_net may be configured to limit the number of new connections
125 from same IP to some value (connect-max).
127 Fixed the load_balance filter.
129 --- 1.0.17 2009/06/16
131 Fix path for metaproxy executable for Debian init.d script.
133 --- 1.0.16 2009/06/10
135 SRU to Z39.50 filter honors x-username and x-password. If only
136 x-username is given that translates to open authentication (Z39.50v2). If
137 both x-username and x-password is present that translates to idPass
138 authentication (Z39.50v3).
140 New facility to change current working directory (-w).
142 Update to upstream skeleton of init.d script. Should fix bug #2619.
144 Filter session_shared now caches records (used to only cache connections
147 Filter session_shared now invalidates a Z39.50 session if a server
148 returns -1 hits. This facility was also part of yazproxy and gets around
149 a bug in Voyager-based Z39.50 servers.
151 --- 1.0.15 2008/11/18
153 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
155 --- 1.0.14 2008/06/09
157 Fixed the value of SRU record schema in searchRetrieve response. It was set
158 to a fixed value of "dc" before.
160 Serialize identical SRU requests. This is useful if HTTP client software
161 fires identical requests against metaproxy.
163 Allow Z39.50 target to be specified for SRU requests by using SRU extra
164 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
165 avoid static configuration. This facility is handled by the sru_z3950 module
166 and the z3950_client module.
168 Allow maximum number of sockets to be used for a Z39.50 client by the
169 use of SRU extra parameter x-max-sockets. This facility is handled by the
170 sru_z3950 module and the z3950_client module.
172 --- 1.0.13.1 2008/02/29
174 Simplified check for Boost libraries.
176 --- 1.0.13 2008/02/29
178 First Debian package.
180 The sru_z9350 filter now recognizes SRU parameter z-target as being
181 a ZURL of the form host/database .
183 Mergetype may be specified for filter 'multi'.
185 --- 1.0.12 2007/09/19
187 Fixed problem in Makefile WRT library specifictions. This could produce
188 linker errors (when they should not happen).
190 Fixed bug #1341: MetaProxy returning different results. Problem was that
191 fix-up of record database did not normalize the database name.
193 Documentation updates for Windows compilation.
195 --- 1.0.11 2007/06/14
197 Fixed problem with logfile being truncated.
199 --- 1.0.10 2007/05/23
201 Fixed bug #1136: Access rights not enforced.
203 Extension for log module. The log category 'access' logs more details.
204 New category 'user-access' added which is simlar to 'access' but adds
205 the Z39.50 user as for all entries in a session.
209 Added support for configurable default/force target/vhost for module Z39.50
214 Implemented filter, session_shared, which optimizes usage of Z39.50
215 sessions and result sets.
217 New filter, record_transform, which converts MARC/XML records.
219 New filter, sru_z3950, which converts SRU to Z39.50 packages.
221 New filter, load_balance, in development.
223 New filter, zeerex_xplain.
225 XML framework for config files started.
227 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
228 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
229 XML config files are checked against RNG and XML Schema's.
231 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
232 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
233 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
234 explain record to YAZ CQL-to-PQF text config file.
238 Added 'timeout' setting for filter frontend_net which specifies the number
239 of seconds a session is idle before it is closed. Default timeout is
244 Database name in records returned set for virt_db/multi filters.
246 Filter session_shared now functional.
248 Log filter can be configured to write to a given file using 'filename'
249 element. Also information category can be specified with 'category'. If
250 filename is omitted, the log filter writes to stdout. See etc/config5.xml
255 Fixed compilation on Windows.
259 Added documentation for the hidenavailable option for the multi filter.
263 Fixed bug #573: Hide errors for individual servers. If the element
264 'hideunavailable' is given in the configuration, individual servers
265 being unavailable are hidden (unless all are unavailable).
267 Fixed bug #574: Database names are recognised case-sensitively.
269 Fixed bug #567: Fix up database name in Name-Plus-Record.
271 Fixed bug #568: Update win/makefile for VS 2005.
273 Fixed bug #569: Some options throws unknown exception.
277 More information about virtual hosts. The 'etc' directory is part of the
282 Build instructions for Windows. NMake makefile part of distribution tar.
288 Filters functional: auth_simple, backend_test, frontend_net, http_file,
289 log, multi, query_rewrite, template, virt_db, z3950_client.
291 Filters in development: session_shared.
293 Pseudo-filters: template, dl
