'update-index --refresh' and 'diff-index' (without --cached) don't honor
the core.preloadindex setting yet. Porcelain commands using these (such as
git [svn] rebase) suffer from this, especially on Windows.

Additionally, in builtin/diff.c, don't preload index status if we don't

Commit b81401c taught the post_rpc function to retry the
http request after prompting for credentials. However, it
did not handle two cases:
1. If we have a large request, we do not retry. That's OK,
since we would have sent a probe (with retry) already.
2. If we are gzipping the request, we do not retry. That
was considered OK, because the intended use was for
push (e.g., listing refs is OK, but actually pushing
objects is not), and we never gzip on push.
This patch teaches post_rpc to retry even a gzipped request.
This has two advantages:
1. It is possible to configure a "half-auth" state for
fetching, where the set of refs and their sha1s are
advertised, but one cannot actually fetch objects.
This is not a recommended configuration, as it leaks
some information about what is in the repository (e.g.,
an attacker can try brute-forcing possible content in
your repository and checking whether it matches your
branch sha1). However, it can be slightly more
convenient, since a no-op fetch will not require a
password at all.
2. It future-proofs us should we decide to ever gzip more
requests.

When we gzip the post data for a smart-http rpc request, we
compute the gzip body and its size inside the "use_gzip"
conditional. We keep track of the body after the conditional
ends, but not the size. Let's remember both, which will
enable us to retry failed gzip requests in a future patch.

If you remove a submodule, in order to keep the repository so that
"git checkout" to an older commit in the superproject history can
resurrect the submodule, the real repository will stay in $GIT_DIR
of the superproject. A later "git submodule add $path" to add a
different submodule at the same path will fail. Diagnose this case
a bit better, and if the user really wants to add an unrelated
submodule at the same path, give the "--name" option to give it a
place in $GIT_DIR of the superproject that does not conflict with
the original submodule.

When renaming orig_args to orig_flags in 98dbe63d (submodule: only
preserve flags across recursive status/update invocations) the call site
of the recursive cmd_status was forgotten. At that place orig_args is
still passed into the recursion, which is always empty since then. This
did not break anything because the orig_flags logic is not needed at all
when a function from the submodule script is called with eval, as that
inherits all the variables set by the option parsing done in the first
level of the recursion.
Now that we know that orig_flags and orig_args aren't needed at all,
let's just remove them from cmd_status().

A test in t7404-submodule-foreach purports to test that
the --cached flag is properly noticed by --recursive calls
to the foreach command as it descends into nested
submodules. However, the test really does not perform this
test since the change it looks for is in a top-level
submodule handled by the first invocation of the command.
To properly test for the flag being passed to recursive
invocations, the change must be buried deeper in the
hierarchy.
Move the change one level deeper so it properly verifies
the recursive machinery of the 'git submodule status'
command.

Use string_list_split_in_place() to split the comma-separated
parameters string. This simplifies the code and also fixes a bug: the
old code made calls like
memcmp(p, "lines", p_len)
which needn't work if p_len is different than the length of the
constant string (and could illegally access memory if p_len is larger
than the length of the constant string).
When p_len was less than the length of the constant string, the old
code would have allowed some abbreviations to be accepted (e.g., "cha"
for "changes") but this seems to have been a bug rather than a
feature, because (1) it is not documented; (2) no attempt was made to
handle ambiguous abbreviations, like "c" for "changes" vs
"cumulative".

We currently just look at raw blob data when using "-S" to
pickaxe. This is mostly historical, as pickaxe predates the
textconv feature. If the user has bothered to define a
textconv filter, it is more likely that their search string will be
on the textconv output, as that is what they will see in the
diff (and we do not even provide a mechanism for them to
search for binary needles that contain NUL characters).
This patch teaches "-S" to use textconv, just as we
already do for "-G".
Signed-off-by: Jeff King <peff@peff.net>
If we are given an empty pickaxe needle like "git log -S ''",
it is impossible for us to find anything (because no matter
what the content, the count will always be 0). We currently
check this at the lowest level of contains(). Let's hoist
the logic much earlier to has_changes(), so that it is
simpler to return our answer before loading any blob data.
Signed-off-by: Jeff King <peff@peff.net>
If you use "-G" to grep a diff, we will apply a configured
textconv filter to the data before generating the diff.
However, if the diff is an addition or deletion, we do not
bother running the diff at all, and just look for the token
in the added (or removed) content. This works because we
know that the diff must contain every line of content.
However, while we used the textconv-derived buffers in the
regular diff, we accidentally passed the original unmodified
buffers to regexec when checking the added or removed
content. This could lead to an incorrect answer.
Worse, in some cases we might have a textconv buffer but no
original buffer (e.g., if we pulled the textconv data from
cache, or if we reused a working tree file when generating
it). In that case, we could actually feed NULL to regexec
and segfault.
