In 0b294c0abf (make deleting a missing ref more quiet, 2008-07-08), we
added a test to verify that deleting an already-deleted ref does not
show an error.
Our test simply looks for the substring 'error' in the output of the
`git push`, which might look innocuous on the face of it.
Suppose, however, that you are a big fan of whales. Or even better: your
IT administrator has a whale of a time picking cute user names, e.g.
referring to you (due to your like of India Pale Ales) as "one of the
cuter rorquals" (see https://en.wikipedia.org/wiki/Rorqual to learn a
thing or two about rorquals) and hence your home directory becomes
/home/cuterrorqual. If you now run t5404, it fails! Why? Because the
test calls `git push origin :b3` which outputs:
To /home/cuterrorqual/git/t/trash directory.t5404-tracking-branches/.
- [deleted] b3
Note how there is no error displayed in that output? But of course
"error" is a substring of "cuterrorqual". And so that `grep error
output` finds something.
This bug was not, actually, caught having "error" as a substring of the
user name but while working in a worktree called "colorize-push-errors",
whose name was part of that output, too, suggesting that not even
testing for the *word* `error` via `git grep -w error output` would fix
the underlying issue.
This patch chooses instead to look for the prefix "error:" at the
beginning of the line, so that there can be no ambiguity that any catch
was indeed a message generated by Git's `error_builtin()` function.

Commit 260d408e32 (config: use getc_unlocked when reading
from file, 2015-04-16) taught git_config_from_file() to lock
the filehandle so that we could safely use the faster
unlocked functions to access the handle.
However, it split the logic into two places:
1. The master lock/unlock happens in git_config_from_file().
2. The decision to use the unlocked functions happens in
do_config_from_file().
That means that if anybody calls the latter function, they
will accidentally use the unlocked functions without holding
the lock. And indeed, git_config_from_stdin() does so.
In practice, this hasn't been a problem since this code
isn't generally multi-threaded (and even if some Git program
happened to have another thread running, it's unlikely to be
reading from stdin). But it's a good practice to make sure
we're always holding the lock before using the unlocked
functions.

Commit f57f37e2e1 (files-backend: remove the use of
git_path(), 2017-03-26) introduced a regression when a
relative $GIT_DIR is used in a working tree:
- when we initialize the ref backend, we make a copy of
get_git_dir(), which may be relative
- later, we may call setup_work_tree() and chdir to the
root of the working tree
- further calls to the ref code will use the stored git
directory, but relative paths will now point to the
wrong place
The new test in t1501 demonstrates one such instance (the
bug causes us to write the ref update to the nonsense
"relative/relative/.git").
Since setup_work_tree() now uses chdir_notify, we can just
ask it update our relative paths when necessary.

When we change to the top of the working tree, we manually
re-adjust $GIT_DIR and call set_git_dir() again, in order to
update any relative git-dir we'd compute earlier.
Instead of the work-tree code having to know to call the
git-dir code, let's use the new chdir_notify interface.
There are two spots that need updating, with a few
subtleties in each:
1. the set_git_dir() code needs to chdir_notify_register()
so it can be told when to update its path.
Technically we could push this down into repo_set_gitdir(),
so that even repository structs besides the_repository
could benefit from this. But that opens up a lot of
complications:
- we'd still need to touch set_git_dir(), because it
does some other setup (like setting $GIT_DIR in the
environment)
- submodules using other repository structs get
cleaned up, which means we'd need to remove them
from the chdir_notify list
- it's unlikely to fix any bugs, since we shouldn't
generally chdir() in the middle of working on a
submodule
2. setup_work_tree now needs to call chdir_notify(), and
can lose its manual set_git_dir() call.
Note that at first glance it looks like this undoes the
absolute-to-relative optimization added by 044bbbcb63
(Make git_dir a path relative to work_tree in
setup_work_tree(), 2008-06-19). But for the most part
that optimization was just _undoing_ the
relative-to-absolute conversion which the function was
doing earlier (and which is now gone).
It is true that if you already have an absolute git_dir
that the setup_work_tree() function will no longer make
it relative as a side effect. But:
- we generally do have relative git-dir's due to the
way the discovery code works
- if we really care about making git-dir's relative
when possible, then we should be relativizing them
earlier (e.g., when we see an absolute $GIT_DIR we
could turn it relative, whether we are going to
chdir into a worktree or not). That would cover all
cases, including ones that 044bbbcb63 did not.

If one part of the code does a permanent chdir(), then this
invalidates any relative paths that may be held by other
parts of the code. For example, setup_work_tree() moves us
to the top of the working tree, which may invalidate a
previously stored relative gitdir.
We've hacked around this case by teaching setup_work_tree()
to re-run set_git_dir() with an adjusted path, but this
stomps all over the idea of module boundaries.
setup_work_tree() shouldn't have to know all of the places
that need to be fed an adjusted path. And indeed, there's at
least one other place (the refs code) which needs adjusting.
Let's provide an API to let code that stores relative paths
"subscribe" to updates to the current working directory.
This means that callers of chdir() don't need to know about
all subscribers ahead of time; they can simply consult a
dynamically built list.
Note that our helper function to reparent relative paths
uses the simple remove_leading_path(). We could in theory
use the much smarter relative_path(), but that led to some
problems as described in 41894ae3a3 (Use simpler
relative_path when set_git_dir, 2013-10-14). Since we're
aiming to replace the setup_work_tree() code here, let's
follow its lead.
