Just trying to reduce the amount of temporary objects created on the
heap to resolve this OutOfMemory issue with AppFuse, and with the 1.6.5
source, I can reduce memory consumption by putting a guard around when
Strings are created for logging eg:
log("Copying "+fromFile+" to "+toFile, verbosity)
becomes
StringBuffer sb = new StringBuffer("Copying ").append(fromFile).append("
to ");
... (code elided)
//not the same behaviour, but need to try and see : don't log unless
user wants debug output
if (verbosity >= Project.MSG_DEBUG) {
log(sb.append(toFile).toString(), verbosity);
}
This helps as the strings aren't created at all unless the verbosity is
set to DEBUG, however, in Ant 1.7, even with this change, there is an
OutOfMemory error. Basically some of the 1.7 tasks are consuming much
more memory than the 1.6.5 codebase.
In general though, the logging mechanism is always going to create a lot
of temporary cruft as it stands, and this is perhaps one area where
there could be some refactoring?
