Sorry I missed this before. As you said, in Johannes's version the ceiling directories are the last directories we look in, whereas in my implementation, they are the first directories we do not look in. I made this choice because it makes more sense for me to set my ceiling to "/home", rather than "/home/dreiss", so it will work even if I am in another user's homedir. There is also a difference in how they handle the case where the cwd is a ceiling directory, but I think it is worth sorting out the first issue first. --David Johannes Sixt wrote: > Johannes Schindelin schrieb: >> Hi, >> >> On Fri, 16 May 2008, Johannes Sixt wrote: >> >>> Johannes Schindelin schrieb: >>>> +'GIT_CEILING_DIRECTORIES':: >>>> + If set (to a colon delimited list of absolute directories), Git >>>> + will refuse to look for the .git/ directory further when hitting >>>> + one of those directories (otherwise it would traverse the parent >>>> + directories until hitting the root directory). >>> Hmm. >>> >>> Looking at the current implementation, this should be written as: >>> >>> If set to a colon delimited list of absolute directories, >>> and the current directory is in or below one of them, then >>> these are the top-most directories in which Git will look for >>> a .git/ directory (otherwise it would traverse the parent >>> directories until hitting the root directory). >> >> According to the test case >> >> GIT_CEILING_DIRECTORIES="$CWD/X:$CWD/subdir" && >> export GIT_CEILING_DIRECTORIES && >> (cd subdir && test_must_fail git rev-parse --git-dir) >> >> this is not the case.
