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/.iÿÿÿÿcCs;||_d|_||_||_||_|iƒdS(Ni(tftheldttimeoutt releasefntdescR(tselftfileRRR((s!/sys/lib/python/mercurial/lock.pyt__init__ s      cCs>|io&tiddtddƒd|_n|iƒdS(Ns$use lock.release instead of del locktcategoryt stacklevelii(RtwarningstwarntDeprecationWarningtrelease(R((s!/sys/lib/python/mercurial/lock.pyt__del__(s    cCs |i}xy|iƒdSWq tij oi}|djo/tidƒ|djo|d8}q q ntiti|i|i |i ƒ‚q Xq dS(Nii( RttrylockterrortLockHeldttimetsleepterrnot ETIMEDOUTtfilenameRtlocker(RRtinst((s!/sys/lib/python/mercurial/lock.pyR4s     cCs*|io|id7_dSntidjotiƒt_ndtitiƒf}xÆ|ip»y ti ||i ƒd|_Wq`t t fj o‚}|i t ijoB|iƒ}|dj o%tit i|i |i|ƒ‚qq!ti|i |i|i|iƒ‚q`Xq`WdS(Nis%s:%s(RRt_hosttNonetsockett gethostnametostgetpidtutiltmakelockRtOSErrortIOErrorRtEEXISTttestlockRRtEAGAINRtLockUnavailabletstrerrorR(RtlocknametwhyR((s!/sys/lib/python/mercurial/lock.pyRCs$     c Csòti|iƒ}y|iddƒ\}}Wntj o |SnX|tijo|Snyt|ƒ}Wn |SnXti|ƒo|Sny;t|idƒ}|i ƒt i |iƒ|i ƒWnt ij o |SnXdS(soreturn id of locker if lock is valid, else None.
