| 4 | Hi all, |
| 5 | |
| 6 | There is dangerous handling of world file updates throughout portage. The attached patch wraps all world file updates in a write_atomic() function which is designed to prevent interprocess interference and prevent corruption when an 'out of space' error occurs. Brian pointed out that portage_util.writedict() already does a similar routine, but it is designed exclusively to write a dictionary object. |
