The left and right base directories were pointed to the buf field of
two strbufs, which were subject to change.
A contrived test case shows the problem where a file with a long enough
name to force the strbuf to grow is up-to-date (hence the code path is
used where the work tree's version of the file is reused), and then a
file that is not up-to-date needs to be written (hence the code path is
used where checkout_entry() uses the previously recorded base_dir that
is invalid by now).
Let's just copy the base_dir strings for use with checkout_entry(),
never touch them until the end, and release them then. This is an easily
verifiable fix (as opposed to the next-obvious alternative: to re-set
base_dir after every loop iteration).

This happens, because we do not properly initialize the environment
in which the diff is run in the submodule. That means we inherit the
environment from the main process, which sets environment variables.
(Apparently we do set environment variables which we do not set
when not in a submodules, i.e. the .git directory is linked)
This commit, just like fd47ae6a5b (diff: teach diff to display
submodule difference with an inline diff, 2016-08-31) introduces bad
test code (i.e. hard coded hash values), which will be cleanup up in
a later patch.

When we notice that we have a local copy of an incoming
object, we compare the two objects to make sure we haven't
found a collision. Before we get to the actual object
bytes, though, we compare the type and size from
sha1_object_info().
If our local object is corrupted, then the type will be
OBJ_BAD, which obviously will not match the incoming type,
and we'll report "SHA1 COLLISION FOUND" (with capital
letters and everything). This is confusing, as the problem
is not a collision but rather local corruption. We should
report that instead (just like we do if reading the rest of
the object content fails a few lines later).
Note that we _could_ just ignore the error and mark it as a
non-collision. That would let you "git fetch" to replace a
corrupted object. But it's not a very reliable method for
repairing a repository. The earlier want/have negotiation
tries to get the other side to omit objects we already have,
and it would not realize that we are "missing" this
corrupted object. So we're better off complaining loudly
when we see corruption, and letting the user take more
drastic measures to repair (like making a full clone
elsewhere and copying the pack into place).
Note that the test sets transfer.unpackLimit in the
receiving repository so that we use index-pack (which is
what does the collision check). Normally for such a small
push we'd use unpack-objects, which would simply try to
write the loose object, and discard the new one when we see
that there's already an old one.

When sha1_loose_object_info() finds that a loose object file
cannot be stat(2)ed or mmap(2)ed, it returns -1 to signal an
error to the caller. However, if it found that the loose
object file is corrupt and the object data cannot be used
from it, it stuffs OBJ_BAD into "type" field of the
object_info, but returns zero (i.e., success), which can
confuse callers.
This is due to 052fe5eac (sha1_loose_object_info: make type
lookup optional, 2013-07-12), which switched the return to a
strict success/error, rather than returning the type (but
botched the return).
Callers of regular sha1_object_info() don't notice the
difference, as that function returns the type (which is
OBJ_BAD in this case). However, direct callers of
sha1_object_info_extended() see the function return success,
but without setting any meaningful values in the object_info
struct, leading them to access potentially uninitialized
memory.
The easiest way to see the bug is via "cat-file -s", which
will happily ignore the corruption and report whatever
value happened to be in the "size" variable.

Suppose I have a superproject 'super', with two submodules 'super/sub'
and 'super/sub1'. 'super/sub' itself contains a submodule
'super/sub/subsub'. Now suppose I run, from within 'super':
echo hi >sub/subsub/stray-file
echo hi >sub1/stray-file
Currently we get would see the following output in git-status:
git status --short
m sub
? sub1
With this patch applied, the untracked file in the nested submodule is
displayed as an untracked file on the 'super' level as well.
git status --short
? sub
? sub1
This doesn't change the output of 'git status --porcelain=1' for nested
submodules, because its output is always ' M' for either untracked files
or local modifications no matter the nesting level of the submodule.
'git status --porcelain=2' is affected by this change in a nested
submodule, though. Without this patch it would report the direct submodule
as modified and having no untracked files. With this patch it would report
untracked files. Chalk this up as a bug fix.
This bug fix also affects the default output (non-short, non-porcelain)
of git-status, which is not tested here.

If I add an untracked file to a submodule or modify a tracked file,
currently "git status --short" treats the change in the same way as
changes to the current HEAD of the submodule:
$ git clone --quiet --recurse-submodules https://gerrit.googlesource.com/gerrit
$ echo hello >gerrit/plugins/replication/stray-file
$ sed -i -e 's/.*//' gerrit/plugins/replication/.mailmap
$ git -C gerrit status --short
M plugins/replication
This is by analogy with ordinary files, where "M" represents a change
that has not been added yet to the index. But this change cannot be
added to the index without entering the submodule, "git add"-ing it,
and running "git commit", so the analogy is counterproductive.
Introduce new status letters " ?" and " m" for this. These are similar
to the existing "??" and " M" but mean that the submodule (not the
parent project) has new untracked files and modified files, respectively.
The user can use "git add" and "git commit" from within the submodule to
add them.
Changes to the submodule's HEAD commit can be recorded in the index with
a plain "git add -u" and are shown with " M", like today.
To avoid excessive clutter, show at most one of " ?", " m", and " M" for
the submodule. They represent increasing levels of change --- the last
one that applies is shown (e.g., " m" if there are both modified files
and untracked files in the submodule, or " M" if the submodule's HEAD
has been modified and it has untracked files).
While making these changes, we need to make sure to not break porcelain
level 1, which shares code with "status --short". We only change
"git status --short".
Non-short "git status" and "git status --porcelain=2" already handle
these cases by showing more detail:
$ git -C gerrit status --porcelain=2
1 .M S.MU 160000 160000 160000 305c864db28eb0c77c8499bc04c87de3f849cf3c 305c864db28eb0c77c8499bc04c87de3f849cf3c plugins/replication
$ git -C gerrit status
[...]
modified: plugins/replication (modified content, untracked content)
Scripts caring about these distinctions should use --porcelain=2.

Converting that part of the interactive rebase to C code introduced the

Let's fix this.
Note: the flag is called `VERIFY_MSG` instead of the more intuitive
