Verify that a downloaded pack-*.idx file is consistent and valid
as an index file before we rename it into its final destination.
This prevents a corrupt index file from later being treated as a
usable file, confusing readers.
Check that we do not have the pack index file before invoking
fetch_pack_index(); that way, we can do without the has_pack_index()
check in fetch_pack_index().

To ensure we don't leave a corrupt pack file positioned as though
it were a valid pack file, run index-pack on the temporary pack
before we rename it to its final name. If index-pack crashes out
when it discovers file corruption (e.g. GitHub's error HTML at the
end of the file), simply delete the temporary files to cleanup.
By waiting until the pack has been validated before we move it
to its final name, we eliminate a race condition where another
concurrent reader might try to access the pack at the same time
that we are still trying to verify its not corrupt.
Switching from verify-pack to index-pack is a change in behavior,
but it should turn out better for users. The index-pack algorithm
tries to minimize disk seeks, as well as the number of times any
given object is inflated, by organizing its work along delta chains.
The verify-pack logic does not attempt to do this, thrashing the
delta base cache and the filesystem cache.
By recreating the index file locally, we also can automatically
upgrade from a v1 pack table of contents to v2. This makes the
CRC32 data available for use during later repacks, even if the
server didn't have them on hand.

The easiest way to verify a pack index is to open it through the
standard parse_pack_index function, permitting the header check
to happen when the file is mapped. However, the dumb HTTP client
needs to verify a pack index before its moved into its proper file
name within the objects/pack directory, to prevent a corrupt index
from being made available. So permit the caller to specify the
exact path of the index file.
For now we're still using the final destination name within the
sole call site in http.c, but eventually we will start to parse
the temporary path instead.

The dumb HTTP transport should verify an index is completely valid
before trying to use it. That requires checking the header/footer
but also checking the complete content SHA-1. All of this logic is
already in the front half of verify_pack, so pull it out into a new
function that can be reused.

By closing the pack index, a caller can later overwrite the index
with an updated index file, possibly after converting from v1 to
the v2 format. Because p->index_data is NULL after close, on the
next access the index will be opened again and the other members
will be updated with new data.

Most of the time the dumb HTTP transport is run without the verbose
flag set, so we only need the result of sha1_to_hex(sha1) once, to
construct the pack URL. Don't bother with an unnecessary malloc,
copy, free chain of this buffer.
If verbose is set, we'll format the SHA-1 twice now. But this
tiny extra CPU time spent is nothing compared to the slowdown that
is usually imposed by the verbose messages being sent to the tty,
and is entirely trivial compared to the latency involved with the
remote HTTP server sending something as big as a pack file.

The use of git add -u in create_stash isn't always complete. In
particular, if a file has been removed from the index but changed in the
work tree it will not be added to the stash's saved work tree tree
object. When stash then resets the work tree to match HEAD, any changes
will be lost.
To be complete, any work tree file which differs from HEAD needs to be
saved, regardless of whether it still appears in the index or not.
This is achieved with a combination of a diff against HEAD and a call to
update-index with an explicit list of paths that have changed.

Other sections, including the section on core.safecrlf, use the term
"work tree" for the same purpose as the term "the filesystem" is used in

Consider an evil merge of two commits A and B, both of which have a
file 'foo', but the merge result does not have that file.
The combined-diff code learned in 4462731 (combine-diff: do not punt
on removed or added files., 2006-02-06) to concisely show only the
removal, since that is the evil part and the previous contents are
presumably uninteresting.
However, to diagnose an empty merge result, it overloaded the variable
that holds the file's length. This means that the check also triggers
for truncated files. Consequently, such files were not shown in the
diff at all despite the merge being clearly evil.
Fix this by adding a new variable that distinguishes whether the file
was deleted (which is the case 4462731 handled) or truncated. In the
truncated case, we show the full combined diff again, which is rather
spammy but at least does not hide the evilness.

v1.7.0-rc0~18^2 (branch -d: base the "already-merged" safety on the
branch it merges with, 2009-12-29) taught ‘git branch’ a new heuristic
for when it is safe to delete a branch without forcing the issue. It
is safe to delete a branch "topic" without second thought if:
- the branch "topic" is set up to pull from a (remote-tracking,
usually) branch and is fully merged in that "upstream" branch, or
- there is no branch.topic.merge configuration and branch "topic" is
fully merged in the current HEAD.

"git am -3" first tries to apply the patch without any extra trick, and
applies it to a synthesized tree for 3-way merge after the first attempt
fails. "git apply" exits with status 1 for a patch that is well-formed
but is not applicable (and it dies on other errors with non-zereo, non-1
status) and has an optimization to fall back to the 3-way merge only in
the case.
An earlier patch 3ddd170 (am: suppress apply errors when using 3-way,
2009-06-16) squelched diagnostic messages from the first attempt, not to
be shown to the end user. This worked reasonably well if the reason the
first application failed was because the patch was made against a wrong
version.
When the patch is corrupt (e.g. line-wrapped or leading whitespaces got
dropped), however, because the second patch application is not even
attempted, the error message from the first application is never shown
and is forever lost. This message is necessary to locate where the patch
is corrupt and fix it up.
We could fix this issue by reverting 3dd170, or keeping the error message
to somewhere and showing it, but because this is an error codepath, the
easiest is to disable the optimization. The second patch application is
attempted even when the input is corrupt, and it will notice, diagnose,
and stop with an error message.
