People: I have these doubts from a while ago, and while a learned a lot about this through Raymond Hettinger, I still have some loose ends. Don't know if there's an official position or it's just developer common sense (which I still don't have), but I didn't find an article/PEP about this. Such paper exists? For now, I'll ask you about a specific issue: there's this bug open about the reindent.py tool, which has an issue about the reindented code file's metadata (more specific: permissions). So I came up with a solution (small patch, three lines), which leaves the reindented file with the same permissions that the original one. My problem is that I can not decide to commit those changes. We're in beta, and don't know if the changes will be tested enough before the final release, in enough platforms (for now, it's tested on Linux, Win2k and MacOS X). And if I don't commit these now, when? Thank you all! . Facundo
