3 First version with zoom filter.
7 Filter z3950_client may be configured to always send a close APDU
8 to backend target when connection/session is closed. This will only
9 happen if close APDU is not already sent. Enabled by configuration
10 for z3950_client (force_close).
12 Filter virt_db and multi: relay close APDU.
14 Filter virt_db and multi: relay init size parameters
15 preferredMessageSize and maximumRecordSize.
17 Filter sru_z3950: increase init sz parameters from 1MB to 10 MB.
21 RPM package for Metaproxy works for both SLES11 and Centos 5.5.
23 metaproxy-config: exec_prefix, libdir, includedir. Use these variables
24 as determined by configure.
26 RPM: Release includes 'indexdata' name. Use indexdata in release name so
27 this package can be distinguished from other vendors.
31 Fix filter multi: relay idAuthentication parameters.
35 Add metaproxy-config for returning compiler flags, libraries.
39 Fix --with-boost=PREFIX .
43 session_shared: fix use of maintenance thread.
45 Introduce 'start' method for filters and routers. It gets called after
46 configure and after fork, but before processing. This changes API -
47 from libmetaproxy2 to libmetaproxy3.
51 session_shared: ensure backend session is closed if init rejected
54 z3950_client: fix NULL ptr reference that could occur if two clients
55 connected concurrently and if max-sockets was in effect.
59 Fix bug 3497 - Metaproxy unstable while stopping.
61 Fix bug 3495 - SEGV in SRU filter.
65 Filter multi throws diagnostic 'Present Out of Range' when
66 appropriate - rather than returning 0 records.
68 Filter virt_db: fix bad result reuse. Could happen if a result
69 was overriden and a backend did not supported named result sets.
73 Filter log: category access logs diagnostics even if searchStatus
74 or presentStatus is 'success'.
78 The SRU to Z39.50 filter does repeated Z39.50 present requests
79 to fetch all records. Needed when a Z39.50 server returns partial
80 results (due to message size limits).
84 Metaproxy now kills all child processes that are spawned by
85 modules (in case of fork, exec).
89 Debian package now installs /etc/metaproxy/metaproxy.xml which
90 includes all XML files /etc/metaproxy/filters-enabled .
91 The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1).
95 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a
96 development package to facilitate 3rd party Metaproxy modules.
100 Filter virt_db: Close backend filter session when Init rejected is received
101 from it (in which case it's not really closed yet). This will ensure we don't
102 run out of resources such as FDs in this case.
104 sru_z3950 filter: Accept any database (including those not listed).
106 --- 1.0.22 2009/12/03
108 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
109 later which means YAZ 3.0.47 or later.
111 --- 1.0.20 2009/11/19
113 For filter virt_db, the database is a glob pattern and the virtual
114 database sections are consulted in the order given.
116 --- 1.0.19 2009/07/08
118 For filter multi, the target (for routing) may be given as a glob-pattern.
120 More documentation for filters virt_db and multi.
122 Update schema to allow for no database in sru_z3950 filter.
124 --- 1.0.18 2009/06/30
126 Added limit filter to put sleep (penalty) for heavy use.
128 Filter frontend_net may be configured to limit the number of new connections
129 from same IP to some value (connect-max).
131 Fixed the load_balance filter.
133 --- 1.0.17 2009/06/16
135 Fix path for metaproxy executable for Debian init.d script.
137 --- 1.0.16 2009/06/10
139 SRU to Z39.50 filter honors x-username and x-password. If only
140 x-username is given that translates to open authentication (Z39.50v2). If
141 both x-username and x-password is present that translates to idPass
142 authentication (Z39.50v3).
144 New facility to change current working directory (-w).
146 Update to upstream skeleton of init.d script. Should fix bug #2619.
148 Filter session_shared now caches records (used to only cache connections
151 Filter session_shared now invalidates a Z39.50 session if a server
152 returns -1 hits. This facility was also part of yazproxy and gets around
153 a bug in Voyager-based Z39.50 servers.
155 --- 1.0.15 2008/11/18
157 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
159 --- 1.0.14 2008/06/09
161 Fixed the value of SRU record schema in searchRetrieve response. It was set
162 to a fixed value of "dc" before.
164 Serialize identical SRU requests. This is useful if HTTP client software
165 fires identical requests against metaproxy.
167 Allow Z39.50 target to be specified for SRU requests by using SRU extra
168 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
169 avoid static configuration. This facility is handled by the sru_z3950 module
170 and the z3950_client module.
172 Allow maximum number of sockets to be used for a Z39.50 client by the
173 use of SRU extra parameter x-max-sockets. This facility is handled by the
174 sru_z3950 module and the z3950_client module.
176 --- 1.0.13.1 2008/02/29
178 Simplified check for Boost libraries.
180 --- 1.0.13 2008/02/29
182 First Debian package.
184 The sru_z9350 filter now recognizes SRU parameter z-target as being
185 a ZURL of the form host/database .
187 Mergetype may be specified for filter 'multi'.
189 --- 1.0.12 2007/09/19
191 Fixed problem in Makefile WRT library specifictions. This could produce
192 linker errors (when they should not happen).
194 Fixed bug #1341: MetaProxy returning different results. Problem was that
195 fix-up of record database did not normalize the database name.
197 Documentation updates for Windows compilation.
199 --- 1.0.11 2007/06/14
201 Fixed problem with logfile being truncated.
203 --- 1.0.10 2007/05/23
205 Fixed bug #1136: Access rights not enforced.
207 Extension for log module. The log category 'access' logs more details.
208 New category 'user-access' added which is simlar to 'access' but adds
209 the Z39.50 user as for all entries in a session.
213 Added support for configurable default/force target/vhost for module Z39.50
218 Implemented filter, session_shared, which optimizes usage of Z39.50
219 sessions and result sets.
221 New filter, record_transform, which converts MARC/XML records.
223 New filter, sru_z3950, which converts SRU to Z39.50 packages.
225 New filter, load_balance, in development.
227 New filter, zeerex_xplain.
229 XML framework for config files started.
231 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
232 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
233 XML config files are checked against RNG and XML Schema's.
235 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
236 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
237 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
238 explain record to YAZ CQL-to-PQF text config file.
242 Added 'timeout' setting for filter frontend_net which specifies the number
243 of seconds a session is idle before it is closed. Default timeout is
248 Database name in records returned set for virt_db/multi filters.
250 Filter session_shared now functional.
252 Log filter can be configured to write to a given file using 'filename'
253 element. Also information category can be specified with 'category'. If
254 filename is omitted, the log filter writes to stdout. See etc/config5.xml
259 Fixed compilation on Windows.
263 Added documentation for the hidenavailable option for the multi filter.
267 Fixed bug #573: Hide errors for individual servers. If the element
268 'hideunavailable' is given in the configuration, individual servers
269 being unavailable are hidden (unless all are unavailable).
271 Fixed bug #574: Database names are recognised case-sensitively.
273 Fixed bug #567: Fix up database name in Name-Plus-Record.
275 Fixed bug #568: Update win/makefile for VS 2005.
277 Fixed bug #569: Some options throws unknown exception.
281 More information about virtual hosts. The 'etc' directory is part of the
286 Build instructions for Windows. NMake makefile part of distribution tar.
292 Filters functional: auth_simple, backend_test, frontend_net, http_file,
293 log, multi, query_rewrite, template, virt_db, z3950_client.
295 Filters in development: session_shared.
297 Pseudo-filters: template, dl
