When $TMPDIR is within $PWD, pip wheel dies on infinite recursion #7872
During debugging the problem described in #7555 (comment) we ahve realized that simply setting
The target directory itself should be ignored when copying to it.
How to Reproduce
The text was updated successfully, but these errors were encountered:
During a build of extension module within `pip wheel` the source directory is recursively copied in a temporary directory. See pypa#7555 When the temporary directory is inside the source directory (for example by setting `TMPDIR=$PWD/tmp`) this caused an infinite recursion that ended in: [Errno 36] File name too long We prevent that buy never copying the target to the target in _copy_source_tree. Fixes pypa#7872
