1 | 1 | # transaction.py - simple journaling scheme for mercurial |
|
2 | 2 | # |
|
3 | 3 | # This transaction scheme is intended to gracefully handle program |
|
4 | 4 | # errors and interruptions. More serious failures like system crashes |
|
5 | 5 | # can be recovered with an fsck-like tool. As the whole repository is |
|
6 | 6 | # effectively log-structured, this should amount to simply truncating |
|
7 | 7 | # anything that isn't referenced in the changelog. |
