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 .

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.

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
