When we replaced the old shell script based interactive rebase in
commmit 18633e1a22 ("rebase -i: use the rebase--helper builtin",
2017-02-09) we introduced a regression of functionality in that the
GIT_DIR would be sent to the environment of the exec command as-is.
This generally meant that it would be passed as "GIT_DIR=.git", which
causes problems for any exec command that wants to run git commands in
a subdirectory.
This isn't a very large regression, since it is not that likely that the
exec command will run a git command, and even less likely that it will
need to do so in a subdir. This regression was discovered by a build
system which uses git-describe to find the current version of the build
system, and happened to do so from the src/ sub directory of the
project.
Fix this by passing in the absolute path of the git directory into the
child environment.

Since dc39e09942 (files_ref_store: use a transaction to update packed
refs, 2017-09-08), failure to lock a reference has been handled
incorrectly by `files_transaction_prepare()`. If
`lock_ref_for_update()` fails in the lock-acquisition loop of that
function, it sets `ret` then breaks out of that loop. Prior to
dc39e09942, that was OK, because the only thing following the loop was
the cleanup code. But dc39e09942 added another blurb of code between
the loop and the cleanup. That blurb sometimes resets `ret` to zero,
making the cleanup code think that the locking was successful.
Specifically, whenever
* One or more reference deletions have been processed successfully in
the lock-acquisition loop. (Processing the first such reference
causes a packed-ref transaction to be initialized.)
* Then `lock_ref_for_update()` fails for a subsequent reference. Such
a failure can happen for a number of reasons, such as the old SHA-1
not being correct, lock contention, etc. This causes a `break` out
of the lock-acquisition loop.
* The `packed-refs` lock is acquired successfully and
`ref_transaction_prepare()` succeeds for the packed-ref transaction.
This has the effect of resetting `ret` back to 0, and making the
cleanup code think that lock acquisition was successful.
In that case, any reference updates that were processed prior to
breaking out of the loop would be carried out (loose and packed), but
the reference that couldn't be locked and any subsequent references
would silently be ignored.
This can easily cause data loss if, for example, the user was trying
to push a new name for an existing branch while deleting the old name.
After the push, the branch could be left unreachable, and could even
subsequently be garbage-collected.
This problem was noticed in the context of deleting one reference and
creating another in a single transaction, when the two references D/F
conflict with each other, like
git update-ref --stdin <<EOF
delete refs/foo
create refs/foo/bar HEAD
EOF
This triggers the above bug because the deletion is processed
successfully for `refs/foo`, then the D/F conflict causes
`lock_ref_for_update()` to fail when `refs/foo/bar` is processed. In
this case the transaction *should* fail, but instead it causes
`refs/foo` to be deleted without creating `refs/foo`. This could
easily result in data loss.
The fix is simple: instead of just breaking out of the loop, jump
directly to the cleanup code. This fixes some tests in t1404 that were
added in the previous commit.

It is currently not allowed, in a single transaction, to add one
reference and delete another reference if the two reference names D/F
conflict with each other (e.g., like `refs/foo/bar` and `refs/foo`).
The reason is that the code would need to take locks
$GIT_DIR/refs/foo.lock
$GIT_DIR/refs/foo/bar.lock
But the latter lock couldn't coexist with the loose reference file
$GIT_DIR/refs/foo
, because `$GIT_DIR/refs/foo` cannot be both a directory and a file at
the same time (hence the name "D/F conflict).
Add a bunch of tests that we cleanly reject such transactions.
In fact, many of the new tests currently fail. They will be fixed in
the next commit along with an explanation.

It's possible for resolve_ref_unsafe() to return NULL (e.g.,
if we are reading and the ref does not exist), in which case
we'll pass NULL to printf. On glibc systems this produces
"(null)", but on others it may segfault.
The tests don't expect any such case, but if we ever did
trigger this, we would prefer to cleanly fail the test with
unexpected input rather than segfault. Let's manually
replace NULL with "(null)". The exact value doesn't matter,
as it won't match any possible ref the caller could expect
(and anyway, the exit code of the program will tell whether
"ref" is valid or not).

The code for handling whitespace with --color-moved
represents partial strings as a pair of pointers. There are
two possible conventions for the end pointer:
1. It points to the byte right after the end of the
string.
2. It points to the final byte of the string.
But we seem to use both conventions in the code:
a. we assign the initial pointers from the NUL-terminated
string using (1)
b. we eat trailing whitespace by checking the second
pointer for isspace(), which needs (2)
c. the next_byte() function checks for end-of-string with
"if (cp > endp)", which is (2)
d. in next_byte() we skip past internal whitespace with
"while (cp < end)", which is (1)
This creates fewer bugs than you might think, because there
are some subtle interactions. Because of (a) and (c), we
always return the NUL-terminator from next_byte(). But all
of the callers of next_byte() happen to handle that
gracefully.
Because of the mismatch between (d) and (c), next_byte()
could accidentally return a whitespace character right at
endp. But because of the interaction of (a) and (b), we fail
to actually chomp trailing whitespace, meaning our endp
_always_ points to a NUL, canceling out the problem.
But that does leave (b) as a real bug: when ignoring
whitespace only at the end-of-line, we don't correctly trim
it, and fail to match up lines.
We can fix the whole thing by moving consistently to one
convention. Since convention (1) is idiomatic in our code
base, we'll pick that one.
The existing "-w" and "-b" tests continue to pass, and a new
"--ignore-space-at-eol" shows off the breakage we're fixing.

Commit fa5ba2c1dd (diff: fix infinite loop with

test to make sure that "--color-moved -b" doesn't run
forever, but the test in question doesn't actually have any
moved lines in it.
Let's scrap that test and add a variant of the existing
"--color-moved -w" test, but this time we'll check that we
find the move with whitespace changes, but not arbitrary
whitespace additions.

We test that lines with whitespace changes are not found by
"--color-moved" by default, but are found if "-w" is added.
Let's add one more twist: a line that has non-whitespace
changes should not be marked as a pure move.
This is perhaps an obvious case for us to get right (and we
do), but as we add more whitespace tests, they will form a
pattern of "make sure this case is a move and this other
case is not".
Note that we have to add a line to our moved block, since
having a too-small block doesn't trigger the "moved"
heuristics. And we also add a line of context to ensure
that there's more context lines than moved lines (so the
diff shows us moving the lines up, rather than moving the
context down).
