I'll have to admit that most of my git usage is via git-svn, so I mostly deal with linear history and some branching, but no real merges in a git sense. This is what I whipped up the other night: http://yhbt.net/git-set-file-times -----------------------------------8<----------------------------------------- #!/usr/bin/perl -w use strict; # sets mtime and atime of files to the latest commit time in git # # This is useful for serving static content (managed by git) # from a cluster of identically configured HTTP servers. HTTP # clients and content delivery networks can get consistent # Last-Modified headers no matter which HTTP server in the # cluster they hit. This should improve caching behavior. # # This does not take into account merges, but if you're updating # every machine in the cluster from the same commit (A) to the # same commit (B), the mtimes will be _consistent_ across all # machines if not necesarily accurate. # # THIS IS NOT INTENDED TO OPTIMIZE BUILD SYSTEMS SUCH AS 'make' # YOU HAVE BEEN WARNED! my %ls = (); my $commit_time; $/ = "\0"; open FH, 'git ls-files -z|' or die $!; while (<FH>) { chomp; $ls{$_} = $_; } close FH; $/ = "\n"; open FH, "git log -r --name-only --no-color --pretty=raw -z @ARGV |" or die $!; while (<FH>) { chomp; if (/^committer .*?
