- Extract of a mail to wx-users to give the context of the problem we are
- trying to solve here:
-
- MC> If I run the command:
- MC> find . -name "*.h" -exec grep linux {} \;
- MC> in the exec sample synchronously from the 'Capture command output'
- MC> menu, wxExecute never returns. I have to xkill it. Has anyone
- MC> else encountered this?
-
- Yes, I can reproduce it too.
-
- I even think I understand why it happens: before launching the external
- command we set up a pipe with a valid file descriptor on the reading side
- when the output is redirected. So the subprocess happily writes to it ...
- until the pipe buffer (which is usually quite big on Unix, I think the
- default is 4Mb) is full. Then the writing process stops and waits until we
- read some data from the pipe to be able to continue writing to it but we
- never do it because we wait until it terminates to start reading and so we
- have a classical deadlock.
-
- Here is the fix: we now read the output as soon as it appears into a temp
- buffer (wxStreamTempBuffer object) and later just stuff it back into the
- stream when the process terminates. See supporting code in wxExecute()
- itself as well.
