It appears to be saying that there used to be a race (involving\n1-second timestamp limitations of filesystems) but now\nthings are done with a slow path fallback for would-race situations so that there is no race in\nany operations any more? If the race is there, the file suggests it isn't a problem\nfor commiting?\n\nI'm just checking because the way I'm planning to migrate is by using a script to\nloop, checking out each snapshot from my existing backup system and commit it into git. I've got\nquite a fast PC with a reasonable amount of memory but using ext3 as filesystem (which\nstill has 1 second timestamp resolution AIUI),\nso it seems entirely plausible that I could get checkouts which alter only a few files\ntaking much, much less than a second. I don't know if any of them also happen to\nhave the same filesize, if they do this pattern seems more likely to meet the condtions of the\n\"race\" than natural, normal git usage, so I want to see if I need to think about this dealing\nwith this issue. My understanding from racy-git.txt is that I don't.\n\nMany thanks for any insight,\n\ncheers, dave tweed\n\n\n\n\n\n\t\t\n___________________________________________________________ \nTry the all-new Yahoo!
