Non-cooperating processes or incorrectly written scripts can ignore Mercurial's locking scheme and stomp all over the repository, so don't do that. Typically used via localrepository.lock() to lock the repository store (.hg/store/) or localrepository.wlock() to lock everything else under .hg/.i����cCs;||_d|_||_||_||_|i�dS(Ni(tftheldttimeoutt releasefntdescR(tselftfileRRR((s./mercurial/lock.pyt__init__ s cCs>|io&tiddtdd�d|_n|i�dS(Ns$use lock.release instead of del locktcategoryt stacklevelii(RtwarningstwarntDeprecationWarningtrelease(R((s./mercurial/lock.pyt__del__(s cCs�|i}x�y|i�dSWqtij oi}|djo/tid�|djo|d8}qqntiti|i|i |i ��qXqdS(Nii(RttrylockterrortLockHeldttimetsleepterrnot ETIMEDOUTtfilenameRtlocker(RRtinst((s./mercurial/lock.pyR4s cCs*|io|id7_dSntidjoti�t_ndtiti�f}x�|ip�y ti ||i �d|_Wq`ttfj o�}|i t ijoB|i�}|dj o%tit i|i |i|��qq!ti|i |i|i|i��q`Xq`WdS(Nis%s:%s(RRt_hosttNonetsockettgethostnametostgetpidtutiltmakelockRtOSErrortIOErrorRtEEXISTttestlockRRtEAGAINRtLockUnavailabletstrerrorR(RtlocknametwhyR((s./mercurial/lock.pyRCs$ cCs�ti|i�}y|idd�\}}Wntj o|SnX|tijo|Snyt|�}Wn|SnXti|�o|Sny;t|id�}|i �t i|i�|i�Wnt ij o|SnXdS(soreturn id of locker if lock is valid, else None.
