* Enable FD_CLOEXEC for lock fd.Zac Medico2013-01-031-1/+10

* locks.py: fix _close_fds docstringv2.2.0_alpha96Zac Medico2012-03-271-1/+0

* Close fewer file descriptors for fork / no exec.Zac Medico2012-03-271-1/+22
| | | | This will fix bug #374335.

* hardlink_lockfile: preserve existing permissionsZac Medico2011-12-141-2/+6
|
* lockfile: deprecate file object or fd parametersZac Medico2011-12-131-1/+11
| | | | | | | Support for file object or integer file descriptor parameters is deprecated due to ambiguity in whether or not it's safe to close the file descriptor, making it prone to "Bad file descriptor" errors or file descriptor leaks.
* hardlink_lockfile: optimize away most link callsZac Medico2011-12-131-30/+41
| | | | | | If fstat shows more than one hardlink, then it's extremely unlikely that the following link call will result in a lock, so optimize away the wasteful link call and sleep or raise TryAgain.
* hardlink_is_mine: return False, never NoneZac Medico2011-12-131-1/+2
|
* locks.py: fix hardlink locks for bug #394195Zac Medico2011-12-131-55/+126
| | | | | | This updates the hardlink locking code to support the non-blocking, lockfile(wantnewlockfile=False), and lockfile(file_object) behaviors which are used by portage code.
* locks.py: make hardlink lock files hiddenZac Medico2011-12-131-4/+6
| | | | | This is for consistency with the behavior for normal lock files, since commit ce44ea3e914098a52bc0d1d995e71661659e77ca (bug #142369).
* locks.py: use flock with PyPy for issue 747Zac Medico2011-12-011-0/+5

* lockfile: use hasattr() instead of dir()Zac Medico2011-06-091-1/+1

| | | | | quiet mode. This is one less import triggered by ebuild-ipc.py, which should be as lightweight as possible.
* Move portage.locks imports to the top of the file.Zac Medico2010-09-031-4/+4
|
* Ensure SystemExit is never caught.Zac Medico2010-08-261-0/+2

* Add some more info to the 'Cannot chown a lockfile' message, sinceZac Medico2010-08-151-1/+5

If flags contains os.O_NONBLOCK then lock() will raise portage.exception.TryAgain instead of blocking.
