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.
