http://nagoya.apache.org/bugzilla/show_bug.cgi?id=25778 [PATCH] Minor optimization for ComponentHelper.initDefaultDefinitions Summary: [PATCH] Minor optimization for ComponentHelper.initDefaultDefinitions Product: Ant Version: 1.6.0 Platform: PC OS/Version: Linux Status: NEW Severity: Enhancement Priority: Other Component: Core AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] CPU profiling of repeated runs of small Ant scripts in the NetBeans IDE (which keeps classes loaded in the same VM between runs) showed a noticeable amount of time being spent in ComponentHelper.initDefaultDefinitions, loading defaults.properties (for both tasks and types) from ant.jar and parsing it. This patch caches the result statically in ComponentHelper. I *think* CH.iDD() is only called once per build, from Project.init() on the entry project (not subprojects), so regular command-line usage would not benefit. However any tool that keeps Ant classes loaded in the JVM between builds would benefit. Should be harmless for command-line Ant except for slight additional memory usage to hold the extra two Properties objects. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
