5 years agocheck_stream_sha1(): handle input underflow
Jeff King [Tue, 30 Oct 2018 23:23:12 +0000 (19:23 -0400)] 
check_stream_sha1(): handle input underflow

This commit fixes an infinite loop when fscking large
truncated loose objects.

The check_stream_sha1() function takes an mmap'd loose
object buffer and streams 4k of output at a time, checking
its sha1. The loop quits when we've output enough bytes (we
know the size from the object header), or when zlib tells us
anything except Z_OK or Z_BUF_ERROR.

The latter is expected because zlib may run out of room in
our 4k buffer, and that is how it tells us to process the
output and loop again.

But Z_BUF_ERROR also covers another case: one in which zlib
cannot make forward progress because it needs more _input_.
This should never happen in this loop, because though we're
streaming the output, we have the entire deflated input
available in the mmap'd buffer. But since we don't check
this case, we'll just loop infinitely if we do see a
truncated object, thinking that zlib is asking for more
output space.

It's tempting to fix this by checking stream->avail_in as
part of the loop condition (and quitting if all of our bytes
have been consumed). But that assumes that once zlib has
consumed the input, there is nothing left to do.  That's not
necessarily the case: it may have read our input into its
internal state, but still have bytes to output.

Instead, let's continue on Z_BUF_ERROR only when we see the
case we're expecting: the previous round filled our output
buffer completely. If it didn't (and we still saw
Z_BUF_ERROR), we know something is wrong and should break
out of the loop.

The bug comes from commit f6371f9210 (sha1_file: add
read_loose_object() function, 2017-01-13), which
reimplemented some of the existing loose object functions.
So it's worth checking if this bug was inherited from any of
those. The answers seems to be no. The two obvious
candidates are both OK:

  1. unpack_sha1_rest(); this doesn't need to loop on
     Z_BUF_ERROR at all, since it allocates the expected
     output buffer in advance (which we can't do since we're
     explicitly streaming here)

  2. check_object_signature(); the streaming path relies on
     the istream interface, which uses read_istream_loose()
     for this case. That function uses a similar "is our
     output buffer full" check with Z_BUF_ERROR (which is
     where I stole it from for this patch!)

t1450: check large blob in trailing-garbage test

Commit cce044df7f (fsck: detect trailing garbage in all
object types, 2017-01-13) added two tests of trailing
garbage in a loose object file: one with a commit and one
with a blob. The point of having two is that blobs would
follow a different code path that streamed the contents,
instead of loading it into a buffer as usual.

At the time, merely being a blob was enough to trigger the
streaming code path. But since 7ac4f3a007 (fsck: actually
fsck blob data, 2018-05-02), we now only stream blobs that
are actually large. So since then, the streaming code path
is not tested at all for this case.

We can restore the original intent of the test by tweaking
core.bigFileThreshold to make our small blob seem large.
There's no easy way to externally verify that we followed
the streaming code path, but I did check before/after using
a temporary debug statement.

mingw: fix isatty() after dup2()

Since a9b8a09c3c30 (mingw: replace isatty() hack, 2016-12-22), we handle
isatty() by special-casing the stdin/stdout/stderr file descriptors,
caching the return value. However, we missed the case where dup2()
overrides the respective file descriptor.

That poses a problem e.g. where the `show` builtin asks for a pager very
early, the `setup_pager()` function sets the pager depending on the
return value of `isatty()` and then redirects stdout. Subsequently,
`cmd_log_init_finish()` calls `setup_pager()` *again*. What should
happen now is that `isatty()` reports that stdout is *not* a TTY and
consequently stdout should be left alone.

mingw: reencode environment variables on the fly (UTF-16 <-> UTF-8)

On Windows, the authoritative environment is encoded in UTF-16. In Git
for Windows, we convert that to UTF-8 (because UTF-16 is *such* a
foreign idea to Git that its source code is unprepared for it).

Previously, out of performance concerns, we converted the entire
environment to UTF-8 in one fell swoop at the beginning, and upon
putenv() and run_command() converted it back.

Having a private copy of the environment comes with its own perils: when
a library used by Git's source code tries to modify the environment, it
does not really work (in Git for Windows' case, libcurl, see
https://github.com/git-for-windows/git/compare/bcad1e6d58^...bcad1e6d58^2
for a glimpse of the issues).

Hence, it makes our environment handling substantially more robust if we
switch to on-the-fly-conversion in `getenv()`/`putenv()` calls. Based
on an initial version in the MSVC context by Jeff Hostetler, this patch
makes it so.

Surprisingly, this has a *positive* effect on speed: at the time when
the current code was written, we tested the performance, and there were
*so many* `getenv()` calls that it seemed better to convert everything
in one go. In the meantime, though, Git has obviously been cleaned up a
bit with regards to `getenv()` calls so that the Git processes spawned
by the test suite use an average of only 40 `getenv()`/`putenv()` calls
over the process lifetime.

Speaking of the entire test suite: the total time spent in the
re-encoding in the current code takes about 32.4 seconds (out of 113
minutes runtime), whereas the code introduced in this patch takes only
about 8.2 seconds in total. Not much, but it proves that we need not be
concerned about the performance impact introduced by this patch.

was added warning against adding any subsequent tests, but since
4614043c8f ("index-pack: use streaming interface for collision test on
large blobs", 2012-05-24) the comment has drifted away from the code,
mentioning two test, when we actually have three.

Instead of having this warning let's just create a new .git directory
specifically for these tests.

As an aside, it would be interesting to instrument the test suite to
run a "git fsck" at the very end (in "test_done"). That would have
errored before this change, and may find other issues #leftoverbits.

5 years agosequencer: break out of loop explicitly
Martin Ågren [Tue, 30 Oct 2018 08:09:37 +0000 (09:09 +0100)] 
sequencer: break out of loop explicitly

It came up in review [1, 2] that this non-idiomatic loop is a bit tricky.
When we find a space, we set `len = i`, which gives us the answer we are
looking for, but which also breaks out of the loop.

It turns out that this loop can confuse compilers as well. My copy of
gcc 7.3.0 realizes that we are essentially evaluating `(len + 1) < len`
and warns that the behavior is undefined if `len` is `INT_MAX`. (Because
the assignment `len = i` is guaranteed to decrease `len`, such undefined
behavior is not actually possible.)

Rewrite the loop to a more idiomatic variant which doesn't muck with
`len` in the loop body. That should help compilers and human readers
figure out what is going on here. But do note that we need to update
`len` since it is not only used just after this loop (where we could
have used `i` directly), but also later in this function.

While at it, reduce the scope of `i`.
