http://issues.apache.org/bugzilla/show_bug.cgi?id=41603 ------- Additional Comments From [EMAIL PROTECTED] 2007-02-14 07:14 ------- I dont know what we will do about this. I believe we could (a) link it to the other bug about script thread safety and (b) check how other script langauges behave. What I will do right now is highlight that parallel is an exceedingly dangerous thing to do. the only 95% safe activity you can do in it is run external stuff using <parallel> or <exec>. It is not meant to be a way to speed up ant. there is a small hint of this in the docs, but I have added a big warning to the front that states more clearly, "play games with parallel and you get to debug the thread safety of the classes you use" <p><b>Warning:</b> While the Ant core is believed to be thread safe, no such guarantees are made about tasks, which are not tested for thread safety during ant's test process. Third party tasks may or may not be thread safe, and some of Ant's core tasks, such as <javac> are definitely not re-entrant. This is because they use libraries that are not designed to be used in a multithreaded environment. </p> <p> The primary use case for <parallel> is to run external programs such as an application server, and the JUnit or TestNG test suites at the same time. Anyone trying to run large Ant task sequences in parallel, such as javadoc and javac at the same time, is implicitly taking on the task of identifying and fixing all concurrency bugs in Ant and its tasks. </p> -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
