This is done so files that will never be writable can be separated from files that are writable but currently locked. :param filename: file to check :raises OSError: as if the file was opened for writing.

The file is renamed to a process-private name before being unlinked, so two processes breaking the same lock cannot delete each other's work (only one rename of a given inode succeeds; the loser gets ``OSError``). After the rename the modification time is re-checked: a value newer than *mtime_before* means a peer recreated the lock between the stale decision and the rename, so we grabbed a live file and must abort, leaving the renamed file in place rather than rolling back (a rollback rename is itself racy — same trade-off as the soft read/write marker break). ``lstat`` is used so a hostile symlink swapped in after the decision is not followed. :param lock_file: path to the lock file to break. :param mtime_before: modification time observed when the lock was judged stale. :raises OSError: if the rename fails (e.g. the file vanished or is not owned in a sticky directory). z.break.N)r ÚgetpidrÚrenameÚlstatrrÚunlink)r#r$Ú break_pathÚ mtime_afters rÚbreak_lock_filer-2s¢€ð"Ð3Ð3¥b¤i¡k¤kÐ3Ð3€J݈O„O×Ò˜:Ñ&Ô&Ð&ðÝ”h˜zÑ*Ô*Ô3ˆ ˆ øÝ ððð؈ˆðøøøà\Ò!Ð!؈݈ÑÔ×ÒÑÔÐÐÐs¼AÁ A$Á#A$)r-r!r)rrr r )rrr r )r#rr$r%r r )Ú __future__rr rrÚerrnorrÚpathlibrrr!r-Ú__all__©r"rúr3s±ðØ"Ð"Ð"Ð"Ð"Ð"à € € € Ø € € € Ø € € € Ø Ð Ð Ð Ð Ð Ð Ð ØÐÐÐÐÐðLðLðLðLð<=ð=ð=ð=ððððð8 ð ð €€€r"
