- Subject: [PATCH 1/2] Prevent infinite recursion with pip wheel with $TMPDIR in
|
| |
- $PWD
|
| |
-
|
| |
- During a build of extension module within `pip wheel` the source directory is
|
| |
- recursively copied in a temporary directory.
|
| |
-
|
| |
- See https://github.com/pypa/pip/issues/7555
|
| |
-
|
| |
- When the temporary directory is inside the source directory
|
| |
- (for example by setting `TMPDIR=$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 https://github.com/pypa/pip/issues/7872
