7 years agofsck: detect trailing garbage in all object types
Jeff King [Fri, 13 Jan 2017 18:00:25 +0000 (13:00 -0500)] 
fsck: detect trailing garbage in all object types

When a loose tree or commit is read by fsck (or any git
program), unpack_sha1_rest() checks whether there is extra
cruft at the end of the object file, after the zlib data.
Blobs that are streamed, however, do not have this check.

For normal git operations, it's not a big deal. We know the
sha1 and size checked out, so we have the object bytes we
wanted.  The trailing garbage doesn't affect what we're
trying to do.

But since the point of fsck is to find corruption or other
problems, it should be more thorough. This patch teaches its
loose-sha1 reader to detect extra bytes after the zlib
stream and complain.

7 years agofsck: parse loose object paths directly
Jeff King [Fri, 13 Jan 2017 17:59:44 +0000 (12:59 -0500)] 
fsck: parse loose object paths directly

When we iterate over the list of loose objects to check, we
get the actual path of each object. But we then throw it
away and pass just the sha1 to fsck_sha1(), which will do a
fresh lookup. Usually it would find the same object, but it
may not if an object exists both as a loose and a packed
object. We may end up checking the packed object twice, and
never look at the loose one.

In practice this isn't too terrible, because if fsck doesn't
complain, it means you have at least one good copy. But
since the point of fsck is to look for corruption, we should
be thorough.

The new read_loose_object() interface can help us get the
data from disk, and then we replace parse_object() with
parse_object_buffer(). As a bonus, our error messages now
mention the path to a corrupted object, which should make it
easier to track down errors when they do happen.

7 years agosha1_file: add read_loose_object() function
Jeff King [Fri, 13 Jan 2017 17:58:16 +0000 (12:58 -0500)] 
sha1_file: add read_loose_object() function

It's surprisingly hard to ask the sha1_file code to open a
_specific_ incarnation of a loose object. Most of the
functions take a sha1, and loop over the various object
types (packed versus loose) and locations (local versus
alternates) at a low level.

However, some tools like fsck need to look at a specific
file. This patch gives them a function they can use to open
the loose object at a given path.

The implementation unfortunately ends up repeating bits of
related functions, but there's not a good way around it
without some major refactoring of the whole sha1_file stack.
We need to mmap the specific file, then partially read the
zlib stream to know whether we're streaming or not, and then
finally either stream it or copy the data to a buffer.

We can do that by assembling some of the more arcane
internal sha1_file functions, but we end up having to
essentially reimplement unpack_sha1_file(), along with the
streaming bits of check_sha1_signature().

Still, most of the ugliness is contained in the new
function, and the interface is clean enough that it may be
reusable (though it seems unlikely anything but git-fsck
would care about opening a specific file).

7 years agot1450: test fsck of packed objects

t1450: test fsck of packed objects

The code paths in fsck for packed and loose objects are
quite different, and it is not immediately obvious that the
packed case behaves well. In particular:

  1. The fsck_loose() function always returns "0" to tell the
     iterator to keep checking more objects. Whereas
     fsck_obj_buffer() (which handles packed objects)
     returns -1. This is OK, because the callback machinery
     for verify_pack() does not stop when it sees a non-zero
     return.

  2. The fsck_loose() function sets the ERROR_OBJECT bit
     when fsck_obj() fails, whereas fsck_obj_buffer() sets it
     only when it sees a corrupt object. This turns out not
     to matter. We don't actually do anything with this bit
     except exit the program with a non-zero code, and that
     is handled already by the non-zero return from the
     function.

So there are no bugs here, but it was certainly confusing to
me. And we do not test either of the properties in t1450
(neither that a non-corruption error will caused a non-zero
exit for a packed object, nor that we keep going after
seeing the first error). Let's test both of those
conditions, so that we'll notice if any of those assumptions
becomes invalid.

sha1_file: fix error message for alternate objects

When we fail to open a corrupt loose object, we report an
error and mention the filename via sha1_file_name().
However, that function will always give us a path in the
local repository, whereas the corrupt object may have come
from an alternate. The result is a very misleading error
message.

Teach the open_sha1_file() and stat_sha1_file() helpers to
pass back the path they found, so that we can report it
correctly.

Note that the pointers we return go to static storage (e.g.,
from sha1_file_name()), which is slightly dangerous.
However, these helpers are static local helpers, and the
names are used for immediately generating error messages.
The simplicity is an acceptable tradeoff for the danger.

t1450: refactor loose-object removal

Commit 90cf590f5 (fsck: optionally show more helpful info

helper, but we already had a remove_object() helper that did
the same thing. Let's combine these into one.

The implementations had a few subtle differences, so I've
tried to take the best of both:

  - the original used "sed", but the newer version avoids
    spawning an extra process

  - the original processed "$*", which was nonsense, as it
    assumed only a single sha1. Use "$1" to make that more
    clear.

  - the newer version ran an extra rev-parse, but it was not
    necessary; it's sole caller already converted the
    argument into a raw sha1

  - the original used "rm -f", whereas the new one uses
    "rm". The latter is better because it may notice a bug
    or other unexpected failure in the test. (The original
    does check that the object exists before we remove it,
    which is good, but that's a subset of the possible
    unexpected conditions).

Jeff King [Sun, 27 Nov 2016 04:31:13 +0000 (23:31 -0500)] 
common-main: stop munging argv[0] path

Since 650c44925 (common-main: call git_extract_argv0_path(),
2016-07-01), the argv[0] that is seen in cmd_main() of
individual programs is always the basename of the
executable, as common-main strips off the full path. This
can produce confusing results for git-daemon, which wants to
re-exec itself.

For instance, if the program was originally run as
"/usr/lib/git/git-daemon", it will try just re-execing
"git-daemon", which will find the first instance in $PATH.
If git's exec-path has not been prepended to $PATH, we may
find the git-daemon from a different version (or no
git-daemon at all).

Normally this isn't a problem. Git commands are run as "git
daemon", the git wrapper puts the exec-path at the front of
$PATH, and argv[0] is already "daemon" anyway. But running
git-daemon via its full exec-path, while not really a
recommended method, did work prior to 650c44925. Let's make
it work again.

The real goal of 650c44925 was not to munge argv[0], but to
reliably set the argv0_path global. The only reason it
munges at all is that one caller, the git.c wrapper,
piggy-backed on that computation to find the command
basename.  Instead, let's leave argv[0] untouched in
common-main, and have git.c do its own basename computation.

While we're at it, let's drop the return value from
git_extract_argv0_path(). It was only ever used in this one
callsite, and its dual purposes is what led to this
confusion in the first place.

Note that by changing the interface, the compiler can
confirm for us that there are no other callers storing the
return value. But the compiler can't tell us whether any of
the cmd_main() functions (besides git.c) were relying on the
basename munging. However, we can observe that prior to
650c44925, no other cmd_main() functions did that munging,
and no new cmd_main() functions have been introduced since

stripspace: respect repository config

The way "git stripspace" reads the configuration was not quite
kosher, in that the code forgot to probe for a possibly existing
repository (note: stripspace is designed to be usable outside the
repository as well).  It read .git/config only when it was run from
the top-level of the working tree by accident.  A recent change
b9605bc4f2 ("config: only read .git/config from configured repos",
2016-09-12) stopped reading the repository-local configuration file
".git/config" unless the repository discovery process is done, so
that .git/config is never read even when run from the top-level,
exposing the old bug more.

When rebasing interactively with a commentChar defined in the
current repository's config, the help text at the bottom of the edit
script potentially used an incorrect comment character. This was not
only funny-looking, but also resulted in tons of warnings like this
one:

alternates: re-allow relative paths from environment

Commit 670c359da (link_alt_odb_entry: handle normalize_path
errors, 2016-10-03) regressed the handling of relative paths
in the GIT_ALTERNATE_OBJECT_DIRECTORIES variable. It's not
entirely clear this was ever meant to work, but it _has_
worked for several years, so this commit restores the
original behavior.

When we get a path in GIT_ALTERNATE_OBJECT_DIRECTORIES, we
add it the path to the list of alternate object directories
as if it were found in objects/info/alternates, but with one
difference: we do not provide the link_alt_odb_entry()
function with a base for relative paths. That function
doesn't turn it into an absolute path, and we end up feeding
the relative path to the strbuf_normalize_path() function.

Most relative paths break out of the top-level directory
(e.g., "../foo.git/objects"), and thus normalizing fails.
Prior to 670c359da, we simply ignored the error, and due to
the way normalize_path_copy() was implemented it happened to
return the original path in this case. We then accessed the
alternate objects using this relative path.

By storing the relative path in the alt_odb list, the path
is relative to wherever we happen to be at the time we do an
object lookup. That means we look from $GIT_DIR in a bare
repository, and from the top of the worktree in a non-bare
repository.

If this were being designed from scratch, it would make
sense to pick a stable location (probably $GIT_DIR, or even
the object directory) and use that as the relative base,
turning the result into an absolute path.  However, given
the history, at this point the minimal fix is to match the
pre-670c359da behavior.

We can do this simply by ignoring the error when we have no
relative base and using the original value (which we now
reliably have, thanks to strbuf_normalize_path()).

That still leaves us with a relative path that foils our
duplicate detection, and may act strangely if we ever
chdir() later in the process. We could solve that by storing
an absolute path based on getcwd(). That may be a good
future direction; for now we'll do just the minimum to fix
the regression.

The new t5615 script demonstrates the fix in its final three
tests. Since we didn't have any tests of the alternates
environment variable at all, it also adds some tests of
absolute paths.
