After we copy the templates into place, we re-read the
config in case we copied in a default config file. But since
git_config() is backed by a cache these days, it's possible
that the call will not actually touch the filesystem at all;
we need to tell it that something has changed behind the
scenes.
Note that we also need to reset the shared_repository
config. At first glance, it seems like this should probably
just be folded into git_config_clear(). But unfortunately
that is not quite right. The shared repository value may
come from config, _or_ it may have been set manually. So
only the caller who knows whether or not they set it is the
one who can clear it (and indeed, if you _do_ put it into
git_config_clear(), then many tests fail, as we have to
clear the config cache any time we set a new config
variable).
There are three tests here. The first two actually pass
already, though it's largely luck: they just don't happen to
actually read any config before we enter the new repo.
But the third one does fail without this patch; we look at
core.sharedrepository while creating the directory, but need
to make sure the value from the template config overrides
it.

When git_config() runs, it looks in the system, user-wide,
and repo-level config files. It gets the latter by calling
git_pathdup(), which in turn calls get_git_dir(). If we
haven't set up the git repository yet, this may simply
return ".git", and we will look at ".git/config". This
seems like it would be helpful (presumably we haven't set up
the repository yet, so it tries to find it), but it turns
out to be a bad idea for a few reasons:
- it's not sufficient, and therefore hides bugs in a
confusing way. Config will be respected if commands are
run from the top-level of the working tree, but not from
a subdirectory.
- it's not always true that we haven't set up the
repository _yet_; we may not want to do it at all. For
instance, if you run "git init /some/path" from inside
another repository, it should not load config from the
existing repository.
- there might be a path ".git/config", but it is not the
actual repository we would find via setup_git_directory().
This may happen, e.g., if you are storing a git
repository inside another git repository, but have
munged one of the files in such a way that the
inner repository is not valid (e.g., by removing HEAD).
We have at least two bugs of the second type in git-init,
introduced by ae5f677 (lazily load core.sharedrepository,
2016-03-11). It causes init to use git_configset(), which
loads all of the config, including values from the current
repo (if any). This shows up in two ways:
1. If we happen to be in an existing repository directory,
we'll read and respect core.sharedrepository from it,
even though it should have no bearing on the new
repository. A new test in t1301 covers this.
2. Similarly, if we're in an existing repo that sets
core.logallrefupdates, that will cause init to fail to
set it in a newly created repository (because it thinks
that the user's templates already did so). A new test
in t0001 covers this.
We also need to adjust an existing test in t1302, which
gives another example of why this patch is an improvement.
That test creates an embedded repository with a bogus
core.repositoryformatversion of "99". It wants to make sure
that we actually stop at the bogus repo rather than
continuing upward to find the outer repo. So it checks that
"git config core.repositoryformatversion" returns 99. But
that only works because we blindly read ".git/config", even
though we _know_ we're in a repository whose vintage we do
not understand.
After this patch, we avoid reading config from the unknown
vintage repository at all, which is a safer choice. But we
need to tweak the test, since core.repositoryformatversion
will not return 99; it will claim that it could not find the
variable at all.

The t1308 test script uses our test-config helper to read
repository-level config, but never actually sets up the
repository. This works because git_config() blindly reads
".git/config" even if we have not configured a repository.
This means that test-config won't work from a subdirectory,
though since it's just a helper for the test scripts, that's
not a big deal.
More important is that the behavior of git_config() is going
to change, and we want to make sure that t1308 continues to
work. We can just use setup_git_directory(), and not the
gentle form; there's no point in being flexible, as it's
just a helper for the tests.

The pager code is often run early in the git.c startup,
before we have actually found the repository. When we ask
git_config() to look for values like core.pager, it doesn't
know where to find the repo-level config, and will blindly
examine ".git/config" if it exists. That's why t7006 shows
that many pager-related features happen to work from the
top-level of a repository, but not from a subdirectory.
This patch pulls that ".git/config" hack explicitly into the
pager code. There are two reasons for this:
1. We'd like to clean up the git_config() behavior, as
looking at ".git/config" when we do not have a
configured repository is often the wrong thing to do.
But we'd prefer not to break the pager config any worse
than it already is.
2. It's one very tiny step on the road to ultimately
making the pager config work consistently. If we
eventually get an equivalent of setup_git_directory()
that _just_ finds the directory and doesn't chdir() or
set up any global state, we could plug it in here
(instead of blindly looking at ".git/config").

While the cached configset interface is more pleasant to
use, it is not appropriate for "early" config like pager
setup, which must sometimes do tricky things like reading
from ".git/config" even when we have not set up the
repository.
As a preparatory step to handling these cases better, let's
switch back to using the callback interface, which gives us
more control.
Note that this is essentially a revert of 586f414 (pager.c:

In git_pager(), we really only care about getting the value
of core.pager. But to do so, we use the git_default_config()
callback, which loads many other values. Ordinarily it
isn't a big deal to load this config an extra time, as it
simply overwrites the values from the previous run. But it's
a bad idea here, for two reasons:
1. The pager setup may be called very early in the
program, before we have found the git repository. As a
result, we may fail to read the correct repo-level
config file. This is a problem for core.pager, too,
but we should at least try to minimize the pollution to
other configured values.
2. Because we call setup_pager() from git.c, basically
every builtin command _may_ end up reading this config
and getting an implicit git_default_config() setup.
Which doesn't sound like a terrible thing, except that
we don't do it consistently; it triggers only when
stdout is a tty. So if a command forgets to load the
default config itself (but depends on it anyway), it
may appear to work, and then mysteriously fail when the
pager is not in use.
We can improve this by loading _just_ the core.pager config
from git_pager().

This dates back to f67b45f (Introduce trivial new pager.c

implementation used fork(). Later, we ended up sticking the
Windows #ifdefs into this file anyway. And then even later,

If we see an explicit "--no-index", we do not bother calling
setup_git_directory_gently() at all. This means that we may
miss out on reading repo-specific config.
It's arguable whether this is correct or not. If we were
designing from scratch, making "git diff --no-index"
completely ignore the repository makes some sense. But we
are nowhere near scratch, so let's look at the existing
behavior:
1. If you're in the top-level of a repository and run an
explicit "diff --no-index", the config subsystem falls
back to reading ".git/config", and we will respect repo
config.
2. If you're in a subdirectory of a repository, then we
still try to read ".git/config", but it generally
doesn't exist. So "diff --no-index" there does not
respect repo config.
3. If you have $GIT_DIR set in the environment, we read
and respect $GIT_DIR/config,
4. If you run "git diff /tmp/foo /tmp/bar" to get an
implicit no-index, we _do_ run the repository setup,
and set $GIT_DIR (or respect an existing $GIT_DIR
variable). We find the repo config no matter where we
started, and respect it.
So we already respect the repository config in a number of
common cases, and case (2) is the only one that does not.
And at least one of our tests, t4034, depends on case (1)
behaving as it does now (though it is just incidental, not
an explicit test for this behavior).
So let's bring case (2) in line with the others by always
running the repository setup, even with an explicit
"--no-index". We shouldn't need to change anything else, as the
implicit case already handles the prefix.

If we see an explicit "git diff --no-index ../foo ../bar",
then we do not set up the git repository at all (we already
know we are in --no-index mode, so do not have to check "are
we in a repository?"), and hence have no "prefix" within the
repository. A patch generated by this command will have the
filenames "a/../foo" and "b/../bar", no matter which
directory we are in with respect to any repository.
However, in the implicit case, where we notice that the
files are outside the repository, we will have chdir()'d to
the top-level of the repository. We then feed the prefix
back to the diff machinery. As a result, running the same
diff from a subdirectory will result in paths that look like
"a/subdir/../../foo".
Besides being unnecessarily long, this may also be confusing
to the user: they don't care about the subdir or the
repository at all; it's just where they happened to be when
running the command. We should treat this the same as the
explicit --no-index case.
One way to address this would be to chdir() back to the
original path before running our diff. However, that's a bit
hacky, as we would also need to adjust $GIT_DIR, which could
be a relative path from our top-level.
Instead, we can reuse the diff machinery's RELATIVE_NAME
option, which automatically strips off the prefix. Note that
this _also_ restricts the diff to this relative prefix, but
that's OK for our purposes: we queue our own diff pairs
manually, and do not rely on that part of the diff code.

We can invoke no-index mode in two ways: by an explicit
request from the user, or implicitly by noticing that we
have two paths, and at least one is outside the repository.
If the user already told us --no-index, there is no need for
us to do the implicit test at all. However, we currently
do, and downgrade our "explicit" to DIFF_NO_INDEX_IMPLICIT.
This doesn't have any user-visible behavior, though it's not
immediately obvious why. We only trigger the implicit check
when we have exactly two non-option arguments. And the only
code that cares about implicit versus explicit is an error
message that we show when we _don't_ have two non-option
arguments.
However, it's worth fixing anyway. Besides being slightly
more efficient, it makes the code easier to follow, which
will help when we modify it in future patches.

Patch-id does not require a repository because it is just
processing the incoming diff on stdin, but it may look at
git config for keys like patchid.stable.
Even though we do not setup_git_directory(), this works from
the top-level of a repository because we blindly look at
".git/config" in this case. But as the included test

When "hash-object" is run without "-w", we don't need to be
in a git repository at all; we can just hash the object and
write its sha1 to stdout. However, if we _are_ in a git
repository, we would want to know that so we can follow the
normal rules for respecting config, .gitattributes, etc.
This happens to work at the top-level of a git repository
because we blindly read ".git/config", but as the included
test shows, it does not work when you are in a subdirectory.
The solution is to just do a "gentle" setup in this case. We
already take care to use prefix_filename() on any filename
arguments we get (to handle the "-w" case), so we don't need
to do anything extra to handle the side effects of repo
setup.
An alternative would be to specify RUN_SETUP_GENTLY for this
command in git.c, and then die if "-w" is set but we are not
in a repository. However, the error messages generated at
the time of setup_git_directory() are more detailed, so it's
better to find out which mode we are in, and then call the
appropriate function.
