|
|
// On MS Windows QProcess creates sub-processes which inherit all
|
|
// inheritable handles, and handles on Windows are inheritable by
|
|
// default. This can cause the lifetime of objects to be unexpectedly
|
|
// extended, which in turn can cause unexpected errors. The motivation
|
|
// for this class was implementing log file rotation using the Boost
|
|
// log library. The current log file's handle gets inherited by any
|
|
// long running sub-process started by QProcess and that causes a
|
|
// sharing violation when attempting to rename the log file on
|
|
// rotation, even though the log library closes the current log file
|
|
// before trying to rename it.
