The report is an XML document +and is triggered for a specific URL path. This is set by +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
