3 Filter virt_db: Close backend filter session when Init rejected is received
4 from it (in which case it's not really closed yet). This will ensure we don't
5 run out of resources such as FDs in this case.
7 sru_z3950 filter: Accept any database (including those not listed).
11 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or
12 later which means YAZ 3.0.47 or later.
16 For filter virt_db, the database is a glob pattern and the virtual
17 database sections are consulted in the order given.
21 For filter multi, the target (for routing) may be given as a glob-pattern.
23 More documentation for filters virt_db and multi.
25 Update schema to allow for no database in sru_z3950 filter.
29 Added limit filter to put sleep (penalty) for heavy use.
31 Filter frontend_net may be configured to limit the number of new connections
32 from same IP to some value (connect-max).
34 Fixed the load_balance filter.
38 Fix path for metaproxy executable for Debian init.d script.
42 SRU to Z39.50 filter honors x-username and x-password. If only
43 x-username is given that translates to open authentication (Z39.50v2). If
44 both x-username and x-password is present that translates to idPass
45 authentication (Z39.50v3).
47 New facility to change current working directory (-w).
49 Update to upstream skeleton of init.d script. Should fix bug #2619.
51 Filter session_shared now caches records (used to only cache connections
54 Filter session_shared now invalidates a Z39.50 session if a server
55 returns -1 hits. This facility was also part of yazproxy and gets around
56 a bug in Voyager-based Z39.50 servers.
60 Fixed reference counting bug in Z39.50 client module (could cause SEGV).
64 Fixed the value of SRU record schema in searchRetrieve response. It was set
65 to a fixed value of "dc" before.
67 Serialize identical SRU requests. This is useful if HTTP client software
68 fires identical requests against metaproxy.
70 Allow Z39.50 target to be specified for SRU requests by using SRU extra
71 parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and
72 avoid static configuration. This facility is handled by the sru_z3950 module
73 and the z3950_client module.
75 Allow maximum number of sockets to be used for a Z39.50 client by the
76 use of SRU extra parameter x-max-sockets. This facility is handled by the
77 sru_z3950 module and the z3950_client module.
79 --- 1.0.13.1 2008/02/29
81 Simplified check for Boost libraries.
87 The sru_z9350 filter now recognizes SRU parameter z-target as being
88 a ZURL of the form host/database .
90 Mergetype may be specified for filter 'multi'.
94 Fixed problem in Makefile WRT library specifictions. This could produce
95 linker errors (when they should not happen).
97 Fixed bug #1341: MetaProxy returning different results. Problem was that
98 fix-up of record database did not normalize the database name.
100 Documentation updates for Windows compilation.
102 --- 1.0.11 2007/06/14
104 Fixed problem with logfile being truncated.
106 --- 1.0.10 2007/05/23
108 Fixed bug #1136: Access rights not enforced.
110 Extension for log module. The log category 'access' logs more details.
111 New category 'user-access' added which is simlar to 'access' but adds
112 the Z39.50 user as for all entries in a session.
116 Added support for configurable default/force target/vhost for module Z39.50
121 Implemented filter, session_shared, which optimizes usage of Z39.50
122 sessions and result sets.
124 New filter, record_transform, which converts MARC/XML records.
126 New filter, sru_z3950, which converts SRU to Z39.50 packages.
128 New filter, load_balance, in development.
130 New filter, zeerex_xplain.
132 XML framework for config files started.
134 Master RelaxNG Compact schema's are found in xml/schema/*.rnc,
135 RelaxNG XML schemas and XML Schema's are generated from RNC syntax.
136 XML config files are checked against RNG and XML Schema's.
138 XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of
139 LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt.
140 Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX
141 explain record to YAZ CQL-to-PQF text config file.
145 Added 'timeout' setting for filter frontend_net which specifies the number
146 of seconds a session is idle before it is closed. Default timeout is
151 Database name in records returned set for virt_db/multi filters.
153 Filter session_shared now functional.
155 Log filter can be configured to write to a given file using 'filename'
156 element. Also information category can be specified with 'category'. If
157 filename is omitted, the log filter writes to stdout. See etc/config5.xml
162 Fixed compilation on Windows.
166 Added documentation for the hidenavailable option for the multi filter.
170 Fixed bug #573: Hide errors for individual servers. If the element
171 'hideunavailable' is given in the configuration, individual servers
172 being unavailable are hidden (unless all are unavailable).
174 Fixed bug #574: Database names are recognised case-sensitively.
176 Fixed bug #567: Fix up database name in Name-Plus-Record.
178 Fixed bug #568: Update win/makefile for VS 2005.
180 Fixed bug #569: Some options throws unknown exception.
184 More information about virtual hosts. The 'etc' directory is part of the
189 Build instructions for Windows. NMake makefile part of distribution tar.
195 Filters functional: auth_simple, backend_test, frontend_net, http_file,
196 log, multi, query_rewrite, template, virt_db, z3950_client.
198 Filters in development: session_shared.
200 Pseudo-filters: template, dl
