提交git（gitolite）仓库提交文件权限（没有更多的trac访问）

设置umask /默认umask没有效果，因为gitolite有它自己的设置。

在〜/ .gitolite.rc

$ REPO_UMASK = 0027;

设置为你喜欢:)

Git只跟踪文件名和这些文件的数据。 它不跟踪文件系统元数据（ownreship，permissions，…）。

如果您希望所有文件具有相同的权限，则umask可以成为有效的解决scheme。

我现在用Git跟踪多台服务器上的系统文件。 我需要一种跟踪权限和数据更改的方法。 我写了一个Ruby脚本来捕获文件权限/所有权并将其放入一个文件中。 这个文件现在可以通过git来跟踪。 每当需要恢复元数据时，我都会使用另一个读取文件并恢复权限的Ruby脚本。

3年来，我经常使用这些脚本，他们没有让我失望。

他们来了：

脚本：save-fs-permissions

#!/usr/bin/ruby RM = "/bin/rm" SORT = "/usr/bin/sort" TMP = "/tmp/save_fs_permissions_#{Time.now.to_i}_#{rand * 899 + 100}" require 'find' IGNORE = [".git"] def numeric2human(m) return sprintf("%c%c%c%c%c%c%c%c%c", (m & 0400 == 0 ? ?- : ?r), (m & 0200 == 0 ? ?- : ?w), (m & 0100 == 0 ? (m & 04000 == 0 ? ?- : ?S) : (m & 04000 == 0 ? ?x : ?s)), (m & 0040 == 0 ? ?- : ?r), (m & 0020 == 0 ? ?- : ?w), (m & 0010 == 0 ? (m & 02000 == 0 ? ?- : ?S) : (m & 02000 == 0 ? ?x : ?s)), (m & 0004 == 0 ? ?- : ?r), (m & 0002 == 0 ? ?- : ?w), (m & 0001 == 0 ? (m & 01000 == 0 ? ?- : ?T) : (m & 01000 == 0 ? ?x : ?t))) end File.open(TMP, "w") do |permissions_file| # TODO: Instead of the current dir, find the .git dir, which could be # the same or outside of the current dir Find.find(".") do |path| next if IGNORE.collect {|ig| !!(path[2..-1] =~ /\A#{ig}/)}.include? true next if File.symlink?(path) stat = File.lstat(path) type = stat.ftype[0..0].sub('f', '-') # Single character for the file type # But a "-" istead of "f" owner_id = stat.uid group_id = stat.gid rules = "#{type}#{numeric2human(stat.mode)}" permissions_file.puts "#{path} #{rules} #{owner_id} #{group_id}" end end `#{SORT} #{TMP} > ./fs-permissions` `#{RM} #{TMP}` 

• 上面的脚本sholud在你的Git工作目录（GIT_WORK_TREE）的根目录下执行。 fs权限，所有者和组ID将被存储在GIT_WORK_TREE目录根目录下的文件fs-permissions中。

脚本：restore-fs-permissions
