Slowdown in ant task execution in 1.8.1 (specifically chmod) on Unix
Hi all,
Just wondering if anyone has experienced a bug I just opened:
https://issues.apache.org/bugzilla/show_bug.cgi?id=49384
As the bug states, the fix for
https://issues.apache.org/bugzilla/show_bug.cgi?id=48746
adds about 400ms of latency on my system for ant tasks that exec
external processes.
For example, chmoding about 100 files takes 41+ seconds vs taking 1
second before.
Reverting the fix for 48746 seems to resolve the performance issue,
although I'm sure it'll probably reintroduce the problem reported in
that bug (I've never noticed it myself though).
Thanks,
Andy

Antoine,
Thanks for the update. I didn't see the change in SVN, which is why I
checked. Should it be in already or am I reading SVN wrong?
http://svn.apache.org/viewvc/ant/core/trunk/src/main/org/apache/tools/ant/taskdefs/PumpStreamHandler.java?diff_format=h&view=log&pathrev=947339
