| Title: Use of index and the "racy git" problem |
| Author: Junio C Hamano |
| Abstract: In order to speed up comparison between files in |
| the work tree and index entries, git compares current |
| lstat(2) information with saved lstat(2) information from |
| whenever it updated the corresponding index entry. A very |
| quick update that does not change file size could therefore |
| make git incorrectly think files in the working tree are |
| unmodified even though they actually are modified. This is |
| called the "racy git" problem (discovered by Pasky), and |
| the entries that would appear clean when they ought not to |
| be because of this problem are called "racily clean". |
| . |
| This document explains how git avoids that problem. |
