Subject: POE::Wheel::Run not exiting "cleanly" from the child
Download (untitled) / with headers
text/plain 1.4k
Hello, I was trying to install POE::Component::SmokeBox on my winxp laptop and it failed a few tests. Digging around more, I found out that the bug actually is in PWR! Attached is a simple testcase that shows this bug. This bug is present on linux and windows. I haven't tested other platforms but I have a good feeling they'll exhibit the same bug. In a nutshell, the PWR child doesn't "cleanly" exit the child if there are any errors before+during the exec. If you have DIE blocks/objects/POE running/etc they will get run in the child! This definitely could have repercussions if the child executed some code it shouldn't have. I've made progress trying to patch this bug and have talked with the win32 people ( jdb++ ) and will be working on this over time. This ticket is left here as a reminder for us all until it's 100% fixed. After talking with Rocco/Philip/others in #poe@irc we decided the right course of action would be to do: 1. Patch PWR to behave properly 2. Patch PWR to warn LOUDLY, I mean LOUDLY if the exec failed on win32 that your process is leaking memory 3. Patch PWR to add docs about this issue 4. Submit a perlbug saying "POSIX::_exit(0) should behave properly on win32" 5. Once 5.14.0 ( or any other release comes out fixing this ) we can have the docs in PWR updated so users on win32 know they should upgrade perls if they execute invalid binaries all day long :) 6. profit? Please keep an eye on this ticket and update it if any changes happen. Thanks! -- ~Apocalypse

POE svn r2875 contains the fix+docs+test for this issue. However, the leak issue still remains. Leaving this ticket as stalled... -- ~Apocalypse
Blame has been successfully passed to a deficiency in POSIX::_exit() on MSWin32.
