There is a race condition when two processes try to write and/or read the same entry at the same time, since each entry consists of two separate files (https://github.com/psf/cachecontrol/issues/324). We therefore have additional logic that makes sure that both files to be present before returning an entry; this fixes the read side of the race condition. For the write side, we assume that the server will only ever return the same data for the same URL, which ought to be the case for files pip is downloading. PyPI does not have a mechanism to swap out a wheel for another wheel, for example. If this assumption is not true, the CacheControl issue will need to be fixed. ع directoryrNcَn•—|€ Jd¦«‚t¦« ¦«||_dS)Nz!Cache directory must not be None.)عsuperع__init__r)عselfrع __class__s €rr zSafeFileCache.__init__2s9ّ€طذ$ذ$ذ&Iر$ش$ذ$ف ‰Œ×زرشذط"ˆŒˆˆrعnamecَک—tj|¦«}t|dd…¦«|gz}tjj|jg|¢RژS)Né)r عencodeعlistعosعpathعjoinr)r!r#عhashedعpartss rع_get_cache_pathzSafeFileCache._get_cache_path7sL€ُ'ش-¨dر3ش3ˆفگVکBکQکB”Zر ش F 8ر+ˆفŒwŒ|کDœNذ3¨Uذ3ذ3ذ3ذ3rعkeycَڑ—| |¦«}|dz}tj |¦«rtj |¦«sdSt ¦«5t|d¦«5}| ¦«cddd¦«cddd¦«S#1swxYwY ddd¦«dS#1swxYwYdS©Nْ.bodyعrb)r-r(r)عexistsrعopenعread)r!r.ع metadata_pathع body_pathعfs rعgetzSafeFileCache.get?sY€à×,ز,¨Sر1ش1ˆ ط!
