--- 1.3.60 2013/08/21 Fix metaproxy-config --libs to return non-mt over mt libs. The -mt versions do not exist as shared objects and cause linker errors for applications linking with Metaproxy. Problem present in versions 1.3.56 - 1.3.59. MP-475 HTML: clean up char checks. Add ptr to HTML parse spec HTML parser stops eating tag when <-char is met MP-473 rewrite: do not even compare content types, if we don't have any the regex_match caused a segfault if we had no content-type in the headers. MP-471 rewrite: within header=... matches only the header value Used to match the whole header line, but we need to use ^$ anchoring for host-relative regexps, and they need to anchor at the ends of the value. MP-470. rewrite: Ruleset functional MP-469 --- 1.3.59 2013/07/12 session_shared: negotiate init sz parameters. By default, session_shared will honor the paramters given by client. An alternative, but not implemented, algorithm would be to only re-use sessions with same sz parameters. This however, could reduce re-use of sessions a lot. Hence this, simple algorithm instead. The negotiation to a maximum sz values can be enabled by using in configuration. This will make session_shared send those values to backends and use returned init values in negotaition to client before session_shared. session_shared: resolve result-set references. The reference is substitued with the query for old set if database match and query type is Type-1. If not the reference will issue a diagnostic. sort filter: relays RecordComposition including elementSet in use for search. http_client: better diagnostics http_client: disables HTTP redirect handling by default. It can be configured with max-redirects in configuration. --- 1.3.58 2013/06/12 Fix loading of filters cql_rpn and sru_z3950 . Was broken by 1.3.57. --- 1.3.57 2013/06/12 Make RouterChain and RouterXML part of public API (libmetaproxy). http_client: honor X-Metaproxy-Proxy as an alternative to the "proxy" configuration. Allows proxy to be set per HTTP request. sru_z3950: For SRU requests recognize x-client prefixes as a way to ingest "database parameters".. The suffix of x-client- serves as database argument name. Multiple may be given. For example: http://path/db/?operation=searchRetrieve&x-client-user=a&x-client-password=b is turned into Z39.50 database db,user=a&password=b --- 1.3.56 2013/05/27 New filter present_chunk. This filter allows splitting of present requests into smaller chunks. New filter sd_remove, which replaces surrogate diagnostics with SUTRS records. This filter tries to deal with clients that breaks when receiving surrogate diagnostics. new filter http_client. Same role as z3950_client, but just for HTTP. Allows Metaproxy to operate as a HTTP proxy. New filter http_rewrite1, which serves as purpose on how to rewrite HTTP content with Metaproxy. Use libboost-system if available, because newer versions of libboost-threads requires libboost-system. Allow frontend_net to serve SSL/HTTPS, because we can specify a server certificate now. --- 1.3.55 2013/04/10 zoom: Torus setting: authenticationMode which may hold values "basic" and "url". --- 1.3.54 2013/03/27 configure: check for Libxslt support in YAZ and rely on definitions from yaz-config, rather than doing own xslt/xml2 checks. Allow timestamp format for log lines to be given with option -m for metaproxy. Similar to yaz-ztest/GFS option -m. Document log category 'line' for log filter. Solr configuration example in etc/config-solr.xml multi: do not mess with request package. For scan and search, database-names were modified and the request package was left with dangling pointers that caused a log filter to fail (request package inspected after multi was invoked). Documentation: fix id of metaproxy-config ref . Documentation: update for USEMARCON support. --- 1.3.53 2013/01/31 record_transform: allow OPACXML to OPAC conversion zoom: document content-proxy zoom: document db parm content-{user,password}, torus_url. Also in the configuration of frontend_net. By default this report is disabled (same as empty value for ). Fix reload problem in init.d script for RPM/Debian. The '/etc/init.d/metaproxy reload' in some cases would stop but not start metaproxy - effectively stopping the service. Don't display start log message when config testing (-t). zoom: avoid CCL message limit of 1K in ZOOM filter. --- 1.3.36 2012/05/10 metaproxy init script reacts to reload which does graceful stop + start and is used by logrorate script. --- 1.3.35 2012/05/09 Fixes for Windows compilation. Metaproxy daemon reacts to SIGUSR1 in which case it will leave existing sessions running but terminate the monitor process that is used in keepalive mode. Change start log message to 'metaproxy start'. Was 'Metaproxy start' before. Consistent with 'metaproxy stop' message. zoom: document zoom's proxy_timeout z3950_client: fixup addinfo for init response virt_db: return other diagnostic if init is rejected. Diagnostic 236: "Access to specified database denied" is returned, but only if init response from backend does not carry diagnostics already. multi: relays user info for first rejected target. The other-information field for init response for first rejected target is in common init response. This ensures that some backend init diagnostics are returned to the frontend. --- 1.3.34 2012/04/25 frontend_log: extend logging (when message is given in config). --- 1.3.33 2012/04/25 zoom: Fix check for proxy. Use diagnostic 1074 for proxy failures. --- 1.3.32 2012/04/24 sru_z3950 filter passes through incoming Z39.50 requests again. Was not handled by mistake in Metaproxy versions 1.3.29, 1.3.30 and 1.3.31. --- 1.3.31 2012/04/24 zoom: fixes for retry/proxy failover logic. More logging. --- 1.3.30 2012/04/23 zoom: return addinfo="proxy failure" for proxy failures. This also changes the scheme for dealing with proxies a bit. zoom now always do proxy check, even if there's no failover. Fortunately, that's not very expensive. zoom: Init rejected wo diagnostics maps to Bib-1:1014. Bib-1 1014, "Init/AC: Authentication System error", seems pretty generic. We don't know why the init would fail; IP, user, block IP, etc. sru_z3950 filter maps this to SRU diagnostic 3: "Authentication error". zoom: guess if invalid SRU response was an auth failure session_shared: disable session retry by default . Can be enabled by restart="true" in resultset section. --- 1.3.29 2012/04/18 zoom: may read cf-proxy's config settings. This reduces manual configuration of the content proxy server host. The ZOOM module will use the old style session.proxyhost if "server" is given (deprecated) and use the new style proxyhost/session if "config_file" is in use. frontend_net: remove incoming requests that can not be handled Requests in queue for filter frontend_net are removed if client closes connection for the session and request is not yet handled. sru_z3950: serialize requests. This is to ensure that pipelined HTTP requests are handled properly. --- 1.3.28 2012/04/04 New class, wrbuf, that wraps YAZ' WRBUF. --- 1.3.27 2012/03/30 Metaproxy daemon is now running as user "metaproxy". This user is managed by package maintainer scripts. The user information is stored in /etc/metaproxy/metaproxy.user . --- 1.3.26 2012/03/20 New filter, sort, that allows sorting of XML records via Z39.50 retrieval. Filter record_transform: USEMarcon support. For example: Filter multi: empty route pattern uses route as default. That is z3950.indexdata.com may use the shorter notation Filter query_rewrite: use config path to locate XSLT. Filter frontend_net: log statistics. If a custom message element in frontend_net configuration it makes the frontend_net filter produce a log entry whenever an operation is completed. The log is always written using yaz_log with the custom message given, the package ID (session ID) , the time the operation has been active (end-to-end) , the threads currently active/total and the size of the request input/output queues. query_rewrite: charset conversion of query terms. This is an optional feature. Enabled by element in configuration with attribute 'from' and 'to' that specifies from/to encodings. The default 'from' encoding is UTF-8. Filter record_transform: honor piggyback searches. Filter zoom: re-connect when database is reused. Re-connect is necessary if a connection is lost or a timeout occurs. If not, we'll be seeing zero hits, when we shouldn't. --- 1.3.25 2012/02/29 zoom: Change scheme for dealing with content proxy URLs. The module now has its own common XSL transform that is enabled by record_xsl attribute in the configuration. This XSL gets parameter cproxyhost that holds the host for the content proxy session . The genearted-url is created only if urlRecipe is enabled. In previous version default value of urlRecipe was ${md-electronic-url}; it is now empty and disabled by default. Also generated-url no longer includes the content proxy host. Content proxying URLs is supposed to the handle in the record_xsl stylesheet. zoom: new setting timeout that specifies timeout for outgoing Z39.50/SRU connections. Default value is 40 (seconds). zoom: tune CCL to Z39.50 diagnostics mapping. Throw Bib-1: 108 "Malformed query" for syntax errors and related ones; throw Bib-1: 3 "Unsupported search" for everything else. Details from the CCL parser is provided as additional-info. multi: new setting hideerrors that makes multi only relay diagnostics to a client if all backends fail. --- 1.3.24 2012/02/23 zoom: empty ccl_map field-mappings disables CCL map. zoom: fix Explain search that could return error if session was re-used. --- 1.3.23 2012/02/10 zoom: returns Explain records for database IR-Explain---1. The target profile records are converted to Explain records via XSLT. session_shared: make error recovery configurable. Whether a search is restarted on errors or not, is configurable by attribute "restart" in element "resultset" in configuration. session_shared: only relay init for first request. session_shared, for each backend class, now only relays first init request (rather than all). The module only needs to save init response info once. This avoids the need to check for session max. --- 1.3.22 2012/02/02 zoom: fix memory leaks. session_shared: maximum number of sessons is configurable. Default value is 100. Result-sets for backends without named result sets are only re-used if databases is identical for a search. This is under the assumption that performance may suffer for those backends when changing the database for each search. multi: combines diagnostics from all backends. All diagnostics from backends are combined into multiple non-surrogate diagnostics; rather than just one diagnostic from first backend. --- 1.3.21 2011/12/27 zoom: relay realm to cproxy parameter file. Configuration: Allow filter collection element inside route. This makes it possible to include multiple filters at once. zoom: nocproxy also disables urlRecipe. --- 1.3.20 2011/12/21 zoom: return diagnostic if CQL sortby conv fails. Diagnostic Bib-1 214 "Illegal sort relation" is returned. Gets translated to SRU diagnostic 90: "Unsupported direction value". zoom: honor database argument nocproxy. This disables creating a content connector session (for non-CF targets, usually) and also relays nocproxy as database argument to a CF target. --- 1.3.19 2011/12/16 zoom: Multiple proxy hosts may be given for proxy rich database parameter. List is comma separated. http_file: decodes URI paths properly. Does not return 404: not found if no prefix are matches. Instead packages are passed on. --- 1.3.18 2011/12/08 zoom: content-{user,password,proxy} are passed on to content proxy system and takes precedence over user,password,proxy . sru_z3950: SRU extra argument x-log-enable=1 enables a search response with a log element including log material from children filters. At this point, only the zoom filter uses this log facility. It will eventually be used by other filters as well. In particular it might be useful for this feature to track all filters in used during a search. zoom: for x-log-enable=1, APDUs sent by ZOOM C, records as received and queries as they are manipulated are logged. zoom: extend addinfo with native diagnostics. Diagnostics as received by ZOOM C are put into addinfo - including ZOOM, HTTP, SRU and Bib-1 diagnostics. This indicates both a backend diagnostic and the original form. zoom: default urlRecipe value is ${md-electronic-url} zoom: target profile setting sruVersion is recognized. --- 1.3.17 2011/11/17 zoom: log target profile record fetched (AKA Torus). --- 1.3.16 2011/11/17 Change target profile parameter CfSubDb to CfSubDB. --- 1.3.15 2011/11/12 zoom: bug fix: realm was relayed to CF targets by mistake (realm only makes sense to the zoom module itself). --- 1.3.14 2011/11/11 zoom: realm may be given as part of database. --- 1.3.13 2011/10/26 Fix Origin class assigment method; was removd by mistake in 1.3.12. --- 1.3.12 2011/10/26 zoom: database args x-name=value are passed through to backend database. SRU filter: user may specify session ID that is passed to log entries that follows. It is specified by using x-session-id in the SRU arguments. zoom: fix null pointer reference which would occur for bad url parameter inside "torus" or if url was not given. --- 1.3.11 2011/09/09 Fix bug in filter session_shared where sessions would not expire properly (session ttl). This in turn could make the target close the connection before expected and session_shared would return diagnostic 2: system temporarily available. --- 1.3.10 2011/09/09 zoom: new target profile setting: sortmap_field. If sortmap_field is given the field is mapped to the value for the sortmap. Values not matching sortmap_field are passed verbatim. zoom: new target profile setting: sortStrategy. One of: "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or CQL sortby depending on whether RPN or CQL is actually sent to the target. --- 1.3.9 2011/08/25 zoom: urlRecipe result is stored in . zoom: For content proxy authentication is stored in param name "auth", instead of "authentication". --- 1.3.8 2011/08/22 zoom: relay schema in SRU mode. Previously recordSchema was not affected by elementSet. --- 1.3.6 2011/08/22 zoom: new target profile element literalTransform that holds XSLT (encoded as string) for target. Only if present and non-zero length it is considered present. This takes precedence over transform. Don't rely on trang anymore for Git checkout builds. Configuration in etc will only be properly validated if trang is available. From now on only relax NC files are bundled with the source dist. Updates to check for Boost unit test (autoconf stuff). On MacOSX this component was not detected when it should be. --- 1.3.5 2011/08/12 z3950_client: mark non-surrogate diagnostics from backend. zoom: a proxy may be specified for HTTP fetch of target profiles. --- 1.3.4 2011/08/01 Honor piggyback. Makes some SRU targets behave that insist on maximumRecords > 0, but also increases performance. --- 1.3.3 2011/08/01 Fix dlpath in installed metaproxy.xml for RPM/Deb package. The file was not update for libdir/metaproxy4 in version 1.3.2. --- 1.3.2 2011/08/01 Change location of Metaproxy modules from libdir/metaproxy to libdir/metaproxy4. Directory libdir/metaproxy is also owned by libmetaproxy3 and, thus, should not be used by libmetaproxy4. New facility to dump APDUs from zoom filter. Enabled by in the zoom filter configuation. zoom filter bug fix: SRU diagnostics received from backend was not properly converted to Bib-1 diagnostics. Package metaproxy depends on libmetaproxy4, same version. --- 1.3.1 2011/07/28 zoom: fix a bug WRT passing authentication parameters to backends. --- 1.3.0 2011/07/27 Fixes for windows Makefile. --- 1.2.10 2011/07/25 Change major version of metaproxy library from 3 to 4. This in turn makes new package names for Debian and RPM. --- 1.2.9 2011/06/27 zoom: enable marc-8 encoding by default for usmarc and opac (in pz2 transforn mode). zoom: configurable element sets for record transforms. zoom: the target profile based transform is specified by element_transform in element torus of of the ZOOM filter configuration ; default value is "pz2". Target profile based retrieval is specified by element_raw in configuration. It will perform same steps, but omit the XSL transform. Default value is "raw". zoom: element set is omitted if not set in profile. But only if pz2 transform is in effect. Previously the default element set was to "F". zoom: For non-CF targets database arguments are parsed. User may supply db,user=myuser&password=mypass for non-CF targets. These values override what's given the authentication from the target profile. session_shared: fix reference to freed memory. Would occur if a search response had non-surrogate diagnostics. --- 1.2.8 2011/06/22 Route may be given for each port in frontend_net. --- 1.2.7 2011/06/22 Documentation for zoom filter. Local target profiles may be specified. Fixes for zoom filter. --- 1.2.6 2011/06/15 First version with zoom filter. --- 1.2.5 2011/05/06 Filter z3950_client may be configured to always send a close APDU to backend target when connection/session is closed. This will only happen if close APDU is not already sent. Enabled by configuration for z3950_client (force_close). Filter virt_db and multi: relay close APDU. Filter virt_db and multi: relay init size parameters preferredMessageSize and maximumRecordSize. Filter sru_z3950: increase init sz parameters from 1MB to 10 MB. --- 1.2.4 2011/01/27 RPM package for Metaproxy works for both SLES11 and Centos 5.5. metaproxy-config: exec_prefix, libdir, includedir. Use these variables as determined by configure. RPM: Release includes 'indexdata' name. Use indexdata in release name so this package can be distinguished from other vendors. --- 1.2.3 2010/10/04 Fix filter multi: relay idAuthentication parameters. --- 1.2.2 2010/09/15 Add metaproxy-config for returning compiler flags, libraries. --- 1.2.1 2010/08/18 Fix --with-boost=PREFIX . --- 1.2.0 2010/07/09 session_shared: fix use of maintenance thread. Introduce 'start' method for filters and routers. It gets called after configure and after fork, but before processing. This changes API - from libmetaproxy2 to libmetaproxy3. --- 1.1.7 2010/06/30 session_shared: ensure backend session is closed if init rejected is received. z3950_client: fix NULL ptr reference that could occur if two clients connected concurrently and if max-sockets was in effect. --- 1.1.6 2010/06/21 Fix bug 3497 - Metaproxy unstable while stopping. Fix bug 3495 - SEGV in SRU filter. --- 1.1.5 2010/06/15 Filter multi throws diagnostic 'Present Out of Range' when appropriate - rather than returning 0 records. Filter virt_db: fix bad result reuse. Could happen if a result was overriden and a backend did not supported named result sets. --- 1.1.4 2010/05/11 Filter log: category access logs diagnostics even if searchStatus or presentStatus is 'success'. --- 1.1.3 2010/04/21 The SRU to Z39.50 filter does repeated Z39.50 present requests to fetch all records. Needed when a Z39.50 server returns partial results (due to message size limits). --- 1.1.2 2010/03/18 Metaproxy now kills all child processes that are spawned by modules (in case of fork, exec). --- 1.1.1 2010/01/28 Debian package now installs /etc/metaproxy/metaproxy.xml which includes all XML files /etc/metaproxy/filters-enabled . The include facility uses YAZ' yaz_xml_include_simple (YAZ 4.0.1). --- 1.1.0 2010/01/20 Package based on YAZ version 4 and YAZ++ 1.2.0. It now includes a development package to facilitate 3rd party Metaproxy modules. --- 1.0.23 2010/01/04 Filter virt_db: Close backend filter session when Init rejected is received from it (in which case it's not really closed yet). This will ensure we don't run out of resources such as FDs in this case. sru_z3950 filter: Accept any database (including those not listed). --- 1.0.22 2009/12/03 Prepare for 64-bit YAZ. yazproxy will still work with YAZ++ 1.1.4 or later which means YAZ 3.0.47 or later. --- 1.0.20 2009/11/19 For filter virt_db, the database is a glob pattern and the virtual database sections are consulted in the order given. --- 1.0.19 2009/07/08 For filter multi, the target (for routing) may be given as a glob-pattern. More documentation for filters virt_db and multi. Update schema to allow for no database in sru_z3950 filter. --- 1.0.18 2009/06/30 Added limit filter to put sleep (penalty) for heavy use. Filter frontend_net may be configured to limit the number of new connections from same IP to some value (connect-max). Fixed the load_balance filter. --- 1.0.17 2009/06/16 Fix path for metaproxy executable for Debian init.d script. --- 1.0.16 2009/06/10 SRU to Z39.50 filter honors x-username and x-password. If only x-username is given that translates to open authentication (Z39.50v2). If both x-username and x-password is present that translates to idPass authentication (Z39.50v3). New facility to change current working directory (-w). Update to upstream skeleton of init.d script. Should fix bug #2619. Filter session_shared now caches records (used to only cache connections and result sets). Filter session_shared now invalidates a Z39.50 session if a server returns -1 hits. This facility was also part of yazproxy and gets around a bug in Voyager-based Z39.50 servers. --- 1.0.15 2008/11/18 Fixed reference counting bug in Z39.50 client module (could cause SEGV). --- 1.0.14 2008/06/09 Fixed the value of SRU record schema in searchRetrieve response. It was set to a fixed value of "dc" before. Serialize identical SRU requests. This is useful if HTTP client software fires identical requests against metaproxy. Allow Z39.50 target to be specified for SRU requests by using SRU extra parameter x-target. Allows SRU to contact arbitrary Z39.50 targets and avoid static configuration. This facility is handled by the sru_z3950 module and the z3950_client module. Allow maximum number of sockets to be used for a Z39.50 client by the use of SRU extra parameter x-max-sockets. This facility is handled by the sru_z3950 module and the z3950_client module. --- 1.0.13.1 2008/02/29 Simplified check for Boost libraries. --- 1.0.13 2008/02/29 First Debian package. The sru_z9350 filter now recognizes SRU parameter z-target as being a ZURL of the form host/database . Mergetype may be specified for filter 'multi'. --- 1.0.12 2007/09/19 Fixed problem in Makefile WRT library specifictions. This could produce linker errors (when they should not happen). Fixed bug #1341: MetaProxy returning different results. Problem was that fix-up of record database did not normalize the database name. Documentation updates for Windows compilation. --- 1.0.11 2007/06/14 Fixed problem with logfile being truncated. --- 1.0.10 2007/05/23 Fixed bug #1136: Access rights not enforced. Extension for log module. The log category 'access' logs more details. New category 'user-access' added which is simlar to 'access' but adds the Z39.50 user as for all entries in a session. Switched to GPL v2. Added support for configurable default/force target/vhost for module Z39.50 client module. --- 1.0.8 2007/01/25 Implemented filter, session_shared, which optimizes usage of Z39.50 sessions and result sets. New filter, record_transform, which converts MARC/XML records. New filter, sru_z3950, which converts SRU to Z39.50 packages. New filter, load_balance, in development. New filter, zeerex_xplain. XML framework for config files started. Master RelaxNG Compact schema's are found in xml/schema/*.rnc, RelaxNG XML schemas and XML Schema's are generated from RNC syntax. XML config files are checked against RNG and XML Schema's. XSLT transformation framework added in xml/xslt/*.xsl, consisting mainly of LOC Marc21 stylesheets found at http://www.loc.gov/marcxml/xslt. Added stylesheet explain2cqlpqftxt.xsl which transforms a standard SRU ZeeReX explain record to YAZ CQL-to-PQF text config file. --- 1.0.7 2006/11/07 Added 'timeout' setting for filter frontend_net which specifies the number of seconds a session is idle before it is closed. Default timeout is 300 (5 minutes). --- 1.0.6 2006/07/07 Database name in records returned set for virt_db/multi filters. Filter session_shared now functional. Log filter can be configured to write to a given file using 'filename' element. Also information category can be specified with 'category'. If filename is omitted, the log filter writes to stdout. See etc/config5.xml for example. --- 1.0.5 2006/05/16 Fixed compilation on Windows. --- 1.0.4 2006/05/16 Added documentation for the hidenavailable option for the multi filter. --- 1.0.3 2006/05/16 Fixed bug #573: Hide errors for individual servers. If the element 'hideunavailable' is given in the configuration, individual servers being unavailable are hidden (unless all are unavailable). Fixed bug #574: Database names are recognised case-sensitively. Fixed bug #567: Fix up database name in Name-Plus-Record. Fixed bug #568: Update win/makefile for VS 2005. Fixed bug #569: Some options throws unknown exception. --- 1.0.2 2006/04/28 More information about virtual hosts. The 'etc' directory is part of the distribution tar. --- 1.0.1 2006/04/27 Build instructions for Windows. NMake makefile part of distribution tar. --- 1.0.0 2006/04/24 More documentation. Filters functional: auth_simple, backend_test, frontend_net, http_file, log, multi, query_rewrite, template, virt_db, z3950_client. Filters in development: session_shared. Pseudo-filters: template, dl --- 0.9 2006/03/27
