Subject: [PATCH] uninstall -v: remove Tracebacks
|
|
|
f65af0 |
|
|
|
f65af0 |
ipa-server-install --uninstall -v -U prints Traceback in its log file.
|
|
|
f65af0 |
This issue happens because it calls subprocess.Popen with close_fds=True
|
|
|
f65af0 |
(which closes all file descriptors in the child process)
|
|
|
f65af0 |
but it is trying to use the file logger in the child process
|
|
|
f65af0 |
(preexec_fn is called in the child just before the child is executed).
|
|
|
f65af0 |
The fix is using the logger only in the parent process.
