Commit 1b77d83cab 'setup_git_directory_gently_1(): resolve symlinks
in ceiling paths' changed the setup code to resolve symlinks in the
entries in GIT_CEILING_DIRECTORIES. Because those entries are
compared textually to the symlink-resolved current directory, an
entry in GIT_CEILING_DIRECTORIES that contained a symlink would have
no effect. It was known that this could cause performance problems
if the symlink resolution *itself* touched slow filesystems, but it
was thought that such use cases would be unlikely. The intention of
the earlier change was to deal with a case when the user has this:
GIT_CEILING_DIRECTORIES=/home/gitster
but in reality, /home/gitster is a symbolic link to somewhere else,
e.g. /net/machine/home4/gitster. A textual comparison between the
specified value /home/gitster and the location getcwd(3) returns
would not help us, but readlink("/home/gitster") would still be
fast.
After this change was released, Anders Kaseorg <andersk@mit.edu>
reported:
> [...] my computer has been acting so slow when I’m not connected to
> the network. I put various network filesystem paths in
> $GIT_CEILING_DIRECTORIES, such as
> /afs/athena.mit.edu/user/a/n/andersk (to avoid hitting its parents
> /afs/athena.mit.edu, /afs/athena.mit.edu/user/a, and
> /afs/athena.mit.edu/user/a/n which all live in different AFS
> volumes). Now when I’m not connected to the network, every
> invocation of Git, including the __git_ps1 in my shell prompt, waits
> for AFS to timeout.
To allow users to work around this problem, give them a mechanism to
turn off symlink resolution in GIT_CEILING_DIRECTORIES entries. All
the entries that follow an empty entry will not be checked for symbolic
links and used literally in comparison. E.g. with these:
GIT_CEILING_DIRECTORIES=:/foo/bar:/xyzzy or
GIT_CEILING_DIRECTORIES=/foo/bar::/xyzzy
we will not readlink("/xyzzy") because it comes after an empty entry.
With the former (but not with the latter), "/foo/bar" comes after an
empty entry, and we will not readlink it, either.

If you are using autoconf and change the configure.ac, the
Makefile will notice that config.status is older than
configure.ac, and will attempt to rebuild and re-run the
configure script to pick up your changes. The first step in
doing so is to run "make configure". Unfortunately, this
tries to include config.mak.autogen, which depends on
config.status, which depends on configure.ac; so we must
rebuild config.status. Which leads to us running "make
configure", and so on.
It's easy to demonstrate with:
make configure
./configure
touch configure.ac
make
We can break this cycle by not re-invoking make to build
"configure", and instead just putting its rules inline into
our config.status rebuild procedure. We can avoid a copy by
factoring the rules into a make variable.

Some implementations of strftime(3) lack support for "%z". Also
there is no need for %s in git-cvsimport as the supplied time is

When passed a local time that was on the boundary of a DST change,
get_tz_offset returned a GMT offset that was incorrect (off by one
hour). This is because the time was converted to GMT and then back to
a time stamp via timelocal() which cannot disambiguate boundary cases
as noted in its documentation.
Modify this algorithm, using an approach suggested in
http://article.gmane.org/gmane.comp.version-control.git/213871
to first convert the timestamp in question to two broken down forms
with localtime() and gmtime(), and then compute what timestamps
these two broken down forms would represent in GMT (i.e. a timezone
that does not have DST issues) by applying timegm() on them. The
difference between the resulting timestamps is the timezone offset.
This avoids the ambigious conversion and allows a correct time to be
returned on every occassion.
