[PATCH] Immediately close all file handles

Hanno Schlichting avatarHanno Schlichting created an issue

This is a copy of http://bugs.python.org/setuptools/issue10:

I'm being pessimistic here and ensuring setuptools closes all files immediately when done with them, in particular for Python VMs that don't use reference counting GC.

Those VMs may not GC/close those files until later, and open file handles are particularly bad on Windows (you can't delete a file that's in use).

This is of low priority

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
