Re: [PATCH v3 0/8] Fix GIT_CEILING_DIRECTORIES that contain symlinks

The log message of the original commit (0454dd93bf) described the
following scenario: a /home partition under which user home directories
are automounted, and setting GIT_CEILING_DIRECTORIES=/home to avoid
hitting /home/.git, /home/.git/objects, and /home/objects (which would
attempt to automount those directories).  I believe that this scenario
would not be slowed down by my patches.

How do you use GIT_CEILING_DIRECTORIES that the proposed changes cause a
slowdown?

Yeah, I was also wondering about that.

Is there another way to accomplish this without the performance hit?
Maybe something that can be solved with configuration?

Without doing the symlink expansion there is no way for git to detect
that GIT_CEILING_DIRECTORIES contains symlinks and is therefore
ineffective.  So the user has no warning about the misconfiguration
(except that git runs slowly).

Perhaps not canonicalize elements on the CEILING list ourselves? If
we make it a user error to put symlinked alias in the variable, and
document it clearly, wouldn't it suffice?

There may be no other choice.  (That, and fix the test suite in another
way to tolerate a $PWD that involves symlinks.)
