server-info: drop objdirlen pointer arithmetic

When writing objects/info/packs, we use the basename of each pack
(i.e., just the "pack-1234abcd.pack" part). We compute that manually by
adding "objdirlen + 6" to the name.

This _should_ work consistently, as we do not include non-local packs,
meaning everything should be in $objdir/pack/. Before f13d7db4af
(server-info.c: use pack_local like everybody else., 2005-12-05), this
was definitely true, since we computed "local" based on comparing the
objdir string.  Since then, we're relying on the code on packfile.c to
match our expectations of p->pack_name and p->local.

I think our expectations do still hold today, but we can be a bit more
defensive by just using pack_basename() to get the base. That
future-proofs us, and should hopefully be more obviously safe to
somebody reading the code.

We keep an array of struct pointers, with each one representing a single
packfile. But for some reason there is a nr_alloc parameter inside each
struct, which has never been used.

This is probably cruft left over from development, where we might have
wanted a nr_alloc to dynamically grow the list. But as it turns out, we
do not dynamically grow the list at all, but rather count up the total
number of packs and use that as a maximum size. So while we're thinking
of this, let's add an assert() that documents (and checks!) that our
allocation and fill loops stay in sync.

happens if we see a long line.

This also lets us drop our custom code to trim the newline.

Probably nobody actually cares about the 1000-char limit (after all, the

When we're writing out a new objects/info/packs file, we read back the

starting with "P", we expect "P pack-1234..." and blindly jump to "line

nothing else, we'd jump past the end of the buffer and start reading
arbitrary memory.

This shouldn't be a big attack vector, as the files are local to the

remote copies of the file for dumb-http fetches, but using a totally
different parser!).

Let's instead use skip_prefix() here, which avoids pointer arithmetic
altogether. Note that this converts our switch statement to an if/else
chain, making it slightly more verbose. But it will also make it easier

http: simplify parsing of remote objects/info/packs

We can use skip_prefix() and parse_oid_hex() to continuously increment
our pointer, rather than dealing with magic numbers. This also fixes a
few small shortcomings:

  - if we see a line with the right prefix, suffix, and length, i.e.
    matching /P pack-.{40}.pack\n/, we'll interpret the middle part as
    hex without checking if it could be parsed. This could lead to us
    looking at uninitialized garbage in the hash array. In practice this
    means we'll just make a garbage request to the server which will
    fail, though it's interesting that a malicious server could convince
    us to leak 40 bytes of uninitialized stack to them.

5 years agopackfile: fix pack basename computation
Jeff King [Fri, 5 Apr 2019 18:06:22 +0000 (14:06 -0400)] 
packfile: fix pack basename computation

When we have a multi-pack-index that covers many packfiles, we try to
avoid opening the .idx for those packfiles. To do that we feed the pack
name to midx_contains_pack(). But that function wants to see only the
basename, which we compute using strrchr() to find the final slash. But
that leaves an extra "/" at the start of our string.

We can fix this by incrementing the pointer. That also raises the
question of what to do when the name does not have a '/' at all. This
should generally not happen (we always find files in "pack/"), but it
doesn't hurt to be defensive here.

Let's wrap all of that up in a helper function and make it publicly
available, since a later patch will need to use it, too.

The tests don't notice because there's nothing about opening those .idx
files that would cause us to give incorrect output. It's just a little
slower. The new test checks this case by corrupting the covered .idx,
and then making sure we don't complain about it.

We also have to tweak t5570, which intentionally corrupts a .idx file
and expects us to notice it. When run with GIT_TEST_MULTI_PACK_INDEX,
this will fail since we now will (correctly) not bother opening the .idx
at all. We can fix that by unconditionally dropping any midx that's
there, which ensures we'll have to read the .idx.

midx: check both pack and index names for containment

A midx file (and the struct we parse from it) contains a list of all of
the covered packfiles, mentioned by their ".idx" names (e.g.,
"pack-1234.idx", etc). And thus calls to midx_contains_pack() expect
callers to provide the idx name.

This works for most of the calls, but the one in open_packed_git_1()
tries to feed a packed_git->pack_name, which is the ".pack" name,
meaning we'll never find a match (even if the pack is covered by the
midx).

We can fix this by converting the ".pack" to ".idx" in the caller.
However, that requires allocating a new string. Instead, let's make
midx_contains_pack() a bit friendlier, and allow it take _either_ the
.pack or .idx variant.

All cleverness in the matching code is credited to René. Bugs are mine.

There's no test here, because while this does fix _a_ bug, it's masked
by another bug in that same caller. That will be covered (with a test)
in the next patch.

pack-revindex: open index if necessary

We can't create a pack revindex if we haven't actually looked at the
index. Normally we would never get as far as creating a revindex without
having already been looking in the pack, so this code never bothered to
double-check that pack->index_data had been loaded.

But with the new multi-pack-index feature, many code paths might not
load the individual pack .idx at all (they'd find objects via the midx
and then open the .pack, but not its index).

This can't yet be triggered in practice, because a bug in the midx code
means we accidentally open up the individual .idx files anyway. But in
preparation for fixing that, let's have the revindex code check that
everything it needs has been loaded.

In most cases this will just be a quick noop. But note that this does
introduce a possibility of error (if we have to open the index and it's

tests: disallow the use of abbreviated options (by default)

Git's command-line parsers support uniquely abbreviated options, e.g.
`git init --ba` would automatically expand `--ba` to `--bare`.

This is a very convenient feature in every day life for Git users, in
particular when tab completion is not available.

However, it is not a good idea to rely on that in Git's test suite, as
something that is a unique abbreviation of a command line option today
might no longer be a unique abbreviation tomorrow.

For example, if a future contribution added a new mode
`git init --babyproofing` and a previously-introduced test case used the
fact that `git init --ba` expanded to `git init --bare`, that future
contribution would now have to touch seemingly unrelated tests just to
keep the test suite from failing.

So let's disallow abbreviated options in the test suite by default.

Note: for ease of implementation, this patch really only touches the
`parse-options` machinery: more and more hand-rolled option parsers are
converted to use that internal API, and more and more scripts are
converted to built-ins (naturally using the parse-options API, too), so
in practice this catches most issues, and is definitely the biggest bang
for the buck.
