Michael Osipov closed VELTOOLS-157. ----------------------------------- > Race condition when instantiating tools > --------------------------------------- > > Key: VELTOOLS-157 > URL: https://issues.apache.org/jira/browse/VELTOOLS-157 > Project: Velocity Tools > Issue Type: Bug > Components: GenericTools, Misc > Affects Versions: 2.0 > Environment: Linux/Tomcat > Reporter: Colin Leroy > Assignee: Claude Brisson > Priority: Minor > Fix For: 3.0 > > Attachments: fix_tool_instantiation_race.patch > > > Hello, > Since Velocity tools are lazy-loaded when necessary only, there's a (wide) > race condition problem during tools instantiation. > Until the tool has been constructed, configure()'d and init()'d, it is not > accessible in the toolbox cache and every invocation of the tool triggers a > new Construct(), configure() and init(). > The problem is unavoidable with any tool for which initialization takes a few > seconds on a heavy enough traffic - for example my Lucene-based search tool > gets typically instantiated two or three times on my production servers, and > can get instantiated dozens of time on an artificially generated load (siege > for example). > The following patch fixes that. > I hope it's good enough to get incorporated, if not, I'm willing to put more > work in it. > Thanks for your help ! -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@velocity.apache.org For additional commands, e-mail: dev-h...@velocity.apache.org
