Provide a mechanism to turn off symlink resolution in ceiling paths
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.

Makefile: avoid infinite loop on configure.ac change
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.

Html documents will be installed to root dir (/) no matter what prefix
is set, if run these commands before `make` and `make install-html`:
$ make configure
$ ./configure --prefix=<PREFIX>
After the installation, all the html documents will copy to rootdir (/),
and:
$ git --html-path
<PREFIX>
$ git help -w something
fatal: '<PREFIX>': not a documentation directory.
This is because the variable "htmldir" points to a undefined variable
"$(docdir)" in file "config.mak.autogen", which is generated by running
`./configure`. By default $(docdir) generated by configure is supposed
be set this way:
but since fc1c5415d69d (Honor configure's htmldir switch, 2013-02-02),
we only set and export htmldir without doing so for PACKAGE_TARNAME
(which is set to 'git' by the configure script).
Add the required two variables "PACKAGE_TARNAME" and "docdir" to file
"config.mak.in" will work this issue around.

Usually we do not pass an empty string to the function hash_name()
because we almost always ask for hash values for a path that is a
candidate to be added to the index. However, check-ignore (and most
likely check-attr, but I didn't check) apparently has a callchain
to ask the hash value for an empty path when it was given a "." from
the top-level directory to ask "Is the path . excluded by default?"
Make sure that hash_name() does not overrun the end of the given
pathname even when it is empty.
Remove a sweep-the-issue-under-the-rug conditional in check-ignore
that avoided to pass an empty string to the callchain while at it.
It is a valid question to ask for check-ignore if the top-level is
set to be ignored by default, even though the answer is most likely
no, if only because there is currently no way to specify such an
entry in the .gitignore file. But it is an unusual thing to ask and
it is not worth optimizing for it by special casing at the top level
of the call chain.

If you run "git log --grep=foo", we will run your regex on
the literal bytes of the commit message. This can provide
confusing results if the commit message is not in the same
encoding as your grep expression (or worse, you have commits
in multiple encodings, in which case your regex would need
to be written to match either encoding). On top of this, we
might also be grepping in the commit's notes, which are
already re-encoded, potentially leading to grepping in a
buffer with mixed encodings concatenated. This is insanity,
but most people never noticed, because their terminal and
their commit encodings all match.
Instead, let's massage the to-be-grepped commit into a
standardized encoding. There is not much point in adding a
flag for "this is the encoding I expect my grep pattern to
match"; the only sane choice is for it to use the log output
encoding. That is presumably what the user's terminal is
using, and it means that the patterns found by the grep will
match the output produced by git.
As a bonus, this fixes a potential segfault in commit_match
when commit->buffer is NULL, as we now build on logmsg_reencode,
which handles reading the commit buffer from disk if
necessary. The segfault can be triggered with:
which arguably does not make any sense (--graph inherently
wants a connected history, and by --no-walk the command line
is telling us to show discrete points in history without
connectivity), and we probably should forbid the
combination, but that is a separate issue.
