Brett Cannon 58f5680462 Issue #18810: Be optimistic with stat calls when seeing if a directory ... exists when checking for a package. Before there was an isdir check and then various isfile checks for possible __init__ files when looking for a package. This change drops the isdir check by leaning on the assumption that a directory will not contain something named after the module being imported which is not a directory. If the module is a package then it saves a stat call. If there is nothing in the directory with the potential package name it also saves a stat call. Only if there is something in the directory named the same thing as the potential package will the number of stat calls increase (due to more wasteful __init__ checks). Semantically there is no change as the isdir check moved down so that namespace packages continue to have no chance of accidentally collecting non-existent directories.		2013-10-18 13:24:13 -04:00
