t3200: verify "branch --list" sanity when rebasing from detached HEAD
"git branch --list" shows an in-progress rebase as:
* (no branch, rebasing <branch>)
master
...
However, if the rebase is started from a detached HEAD, then there is no
<branch>, and it would attempt to print a NULL pointer. The previous
commit fixed this problem, so add a test to verify that the output is
sane in this situation.

branch --list: print useful info whilst interactive rebasing a detached HEAD
When rebasing interactively (rebase -i), "git branch --list" prints
a line indicating the current branch being rebased. This works well
when the interactive rebase is initiated when a local branch is
checked out.
This doesn't play well when the rebase is initiated on a detached
HEAD. When "git branch --list" tries to print information related
to the interactive rebase in this case it tries to print the name
of a branch using an uninitialized variable and thus tries to
print a "null pointer string". As a consequence, it does not provide
useful information while also inducing undefined behaviour.
So, print the point from which the rebase was started when interactive
rebasing a detached HEAD.

In 36db1eddf9 ("git-svn: add --authors-prog option", 2009-05-14) the path
to authors-prog was made absolute because git-svn changes the current
directory in some situations. This makes sense if the program is part of
the repository but prevents searching via $PATH.
The old behaviour is still retained, but if the file does not exists, then
authors-prog is searched for in $PATH as any other command.

add -p: fix 2.17.0-rc* regression due to moved code
Fix a regression in 88f6ffc1c2 ("add -p: only bind search key if
there's more than one hunk", 2018-02-13) which is present in
2.17.0-rc*, but not 2.16.0.
In Perl, regex variables like $1 always refer to the last regex
match. When the aforementioned change added a new regex match between
the old match and the corresponding code that was expecting $1, the $1
variable would always be undef, since the newly inserted regex match
doesn't have any captures.
As a result the "/" feature to search for a string in a hunk by regex
completely broke, on git.git:
$ perl -pi -e 's/Git/Tig/g' README.md
$ ./git --exec-path=$PWD add -p
[..]
Stage this hunk [y,n,q,a,d,j,J,g,/,s,e,?]? s
Split into 4 hunks.
[...]
Stage this hunk [y,n,q,a,d,j,J,g,/,s,e,?]? /Many
Use of uninitialized value $1 in string eq at /home/avar/g/git/git-add--interactive line 1568, <STDIN> line 1.
search for regex? Many
I.e. the initial "/regex" command wouldn't work, and would always emit
a warning and ask again for a regex, now it works as intended again.

config: move flockfile() closer to unlocked functions
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.

refs: use chdir_notify to update cached relative paths
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.
Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.

The set_git_dir() function returns an error if setenv()
fails, but there are zero callers who pay attention to this
return value. If this ever were to happen, it could cause
confusing results, as sub-processes would see a potentially
stale GIT_DIR (e.g., if it is relative and we chdir()-ed to
the root of the working tree).
We _could_ try to fix each caller, but there's really
nothing useful to do after this failure except die. Let's
just lump setenv() failure into the same category as malloc
failure: things that should never happen and cause us to
abort catastrophically.

upload-pack: disable object filtering when disabled by config
When upload-pack gained partial clone support (v2.17.0-rc0~132^2~12,
2017-12-08), it was guarded by the uploadpack.allowFilter config item
to allow server operators to control when they start supporting it.
That config item didn't go far enough, though: it controls whether the
'filter' capability is advertised, but if a (custom) client ignores
the capability advertisement and passes a filter specification anyway,
the server would handle that despite allowFilter being false.
This is particularly significant if a security bug is discovered in
this new experimental partial clone code. Installations without
uploadpack.allowFilter ought not to be affected since they don't
intend to support partial clone, but they would be swept up into being
vulnerable.
Simplify and limit the attack surface by making uploadpack.allowFilter
disable the feature, not just the advertisement of it.

credential: ignore SIGPIPE when writing to credential helpers
The credential subsystem can trigger SIGPIPE when writing to an
external helper if that helper closes its stdin before reading the
whole input. Normally this is rare, since helpers would need to read
that input to make a decision about how to respond, but:
1. It's reasonable to configure a helper which only handles "get"
while ignoring "store". Such a handler might not read stdin
for "store", thereby rapidly closing stdin upon helper exit.
2. A broken or misbehaving helper might exit immediately. That's an
error, but it's not reasonable for it to take down the parent Git
process with SIGPIPE.
Even with such a helper, seeing this problem should be rare. Getting
SIGPIPE requires the helper racily exiting before we've written the
fairly small credential output.

Attempt to clarify what the SHAttered attack means in practice for

I may have gotten some of the nuances wrong, but as far as I know this

[...]As a result [of SHAttered], SHA-1 cannot be considered

we consider it prudent to move to work towards a NewHash should future
