Make the copy_or_link_directory function no longer skip hidden
directories. This function, used to copy .git/objects, currently skips
all hidden directories but not hidden files, which is an odd behaviour.
The reason for that could be unintentional: probably the intention was
to skip '.' and '..' only but it ended up accidentally skipping all
directories starting with '.'. Besides being more natural, the new
behaviour is more permissive to the user.
Also adjust tests to reflect this behaviour change.

There is currently an odd behaviour when locally cloning a repository
with symlinks at .git/objects: using --no-hardlinks all symlinks are
dereferenced but without it, Git will try to hardlink the files with the
link() function, which has an OS-specific behaviour on symlinks. On OSX
and NetBSD, it creates a hardlink to the file pointed by the symlink
whilst on GNU/Linux, it creates a hardlink to the symlink itself.
On Manjaro GNU/Linux:
$ touch a
$ ln -s a b
$ link b c
$ ls -li a b c
155 [...] a
156 [...] b -> a
156 [...] c -> a
But on NetBSD:
$ ls -li a b c
2609160 [...] a
2609164 [...] b -> a
2609160 [...] c
It's not good to have the result of a local clone to be OS-dependent and
besides that, the current behaviour on GNU/Linux may result in broken
symlinks. So let's standardize this by making the hardlinks always point
to dereferenced paths, instead of the symlinks themselves. Also, add
tests for symlinked files at .git/objects/.
Note: Git won't create symlinks at .git/objects itself, but it's better
to handle this case and be friendly with users who manually create them.

Add tests for what happens when we perform a local clone on a repo
containing odd files at .git/object directory, such as symlinks to other
dirs, or unknown files.
I'm bending over backwards here to avoid a SHA-1 dependency. See [1]
for an earlier and simpler version that hardcoded SHA-1s.
This behavior has been the same for a *long* time, but hasn't been
tested for.
There's a good post-hoc argument to be made for copying over unknown
things, e.g. I'd like a git version that doesn't know about the
commit-graph to copy it under "clone --local" so a newer git version
can make use of it.
In follow-up commits we'll look at changing some of this behavior, but
for now, let's just assert it as-is so we'll notice what we'll change
later.

Rename bunch of tests on "git clone" for better organization.
* sb/clone-t57-t56:
clone tests: rename t57* => t56*
|
|
When trying to find a good spot for testing clone with submodules, I
got confused where to add a new test file. There are both tests in t560*
as well as t57* both testing the clone command. t/README claims the
second digit is to indicate the command, which is inconsistent to the
current naming structure.
Rename all t57* tests to be in t56* to follow the pattern of the digits
as laid out in t/README.
It would have been less work to rename t56* => t57* because there are less
files, but the tests in t56* look more basic and I assumed the higher the
last digits the more complicated niche details are tested, so with the patch
now it looks more in order to me.
