sideband: do not read beyond the end of input

<src, n>, but the callee checked src[] as if it were a NUL terminated
buffer.  If src[] had all isspace() bytes in it, we would have made
n negative, and then

 (1) made number of strncasecmp() calls to see if the remaining
     bytes in src[] matched keywords, reading beyond the end of the
     array (this actually happens even if n does not go negative),

     the "you want to use way too much memory" error due to unsigned
     integer overflow.

Fix both issues by making sure we do not go beyond &src[n].

there are merge conflicts error_with_patch() is passed a NULL commit
which causes a segmentation fault when make_patch() tries to look it up.

This commit implements a minimal fix which fixes the crash and allows
the user to successfully commit a conflict resolution with 'git rebase
--continue'. It does not write .git/rebase-merge/patch,
.git/rebase-merge/stopped-sha or update REBASE_HEAD. To sensibly get the
hashes of the merge parents would require refactoring do_merge() to
extract the code that parses the merge parents into a separate function
which error_with_patch() could then use to write the parents into the
stopped-sha file. To create meaningful output make_patch() and 'git
rebase --show-current-patch' would also need to be modified to diff the

sizeof(int*) on some platforms.  Since an enum could be a char or int

knowing the size of a pointer to an enum, so we cannot just forward
declare an enum the way we can a struct.  (Also, modern C++ compilers
apparently define forward declarations of an enum to either be useless

submodule: add more exhaustive up-path testing

The tests added in 63e95beb08 ("submodule: port resolve_relative_url
from shell to C", 2016-04-15) didn't do a good job of testing various
up-path invocations where the up-path would bring us beyond even the
URL in question without emitting an error.

These results look nonsensical, but it's worth exhaustively testing
them before fixing any of this code, so we can see which of these
cases were changed.

2 years agogit-submodule.sh: accept verbose flag in cmd_update to be non-quiet

git-submodule.sh: accept verbose flag in cmd_update to be non-quiet

In a56771a668d (builtin/pull: respect verbosity settings in submodules,
2018-01-25), we made sure to pass on both quiet and verbose flag from
builtin/pull.c to the submodule shell script. However git-submodule doesn't
understand a verbose flag, which results in a bug when invoking

  git pull --recurse-submodules -v [...]

There are a few different approaches to fix this bug:

1) rewrite 'argv_push_verbosity' or its caller in builtin/pull.c to
   cap opt_verbosity at 0. Then 'argv_push_verbosity' would only add
   '-q' if any.

2) Have a flag in 'argv_push_verbosity' that specifies if we allow adding
  -q or -v (or both).

3) Add -v to git-submodule.sh and make it a no-op

(1) seems like a maintenance burden: What if we add code after
the submodule operations or move submodule operations higher up,
then we have altered the opt_verbosity setting further down the line
in builtin/pull.c.

(2) seems like it could work reasonably well without more regressions

(3) seems easiest to implement as well as actually is a feature with the
    last-one-wins rule of passing flags to Git commands.

for_each_*_object: move declarations to object-store.h

The for_each_loose_object() and for_each_packed_object()
functions are meant to be part of a unified interface: they
use the same set of for_each_object_flags, and it's not
inconceivable that we might one day add a single
for_each_object() wrapper around them.

Let's put them together in a single file, so we can avoid
awkwardness like saying "the flags for this function are
over in cache.h". Moving the loose functions to packfile.h
is silly. Moving the packed functions to cache.h works, but
makes the "cache.h is a kitchen sink" problem worse. The
best place is the recently-created object-store.h, since
these are quite obviously related to object storage.

The for_each_*_in_objdir() functions do not use the same
flags, but they are logically part of the same interface as
for_each_loose_object(), and share callback signatures. So
we'll move those, as well, as they also make sense in
object-store.h.

t5310-pack-bitmaps: fix bogus 'pack-objects to file can use bitmap' test

The test 'pack-objects to file can use bitmap' added in 645c432d61
(pack-objects: use reachability bitmap index when generating
non-stdout pack, 2016-09-10) is silently buggy and doesn't check what
it's supposed to.

In 't5310-pack-bitmaps.sh', the 'list_packed_objects' helper function
does what its name implies by running:

  git show-index <"$1" | cut -d' ' -f2

The test in question invokes this function like this:

  list_packed_objects <packa-$packasha1.idx >packa.objects &&
  list_packed_objects <packb-$packbsha1.idx >packb.objects &&
  test_cmp packa.objects packb.objects

Note how these two callsites don't specify the name of the pack index
file as the function's parameter, but redirect the function's standard
input from it.  This triggers an error message from the shell, as it
has no filename to redirect from in the function, but this error is
ignored, because it happens upstream of a pipe.  Consequently, both
invocations produce empty 'pack{a,b}.objects' files, and the
subsequent 'test_cmp' happily finds those two empty files identical.

Fix these two 'list_packed_objects' invocations by specifying the pack
index files as parameters.  Furthermore, eliminate the pipe in that
function by replacing it with an &&-chained pair of commands using an
intermediate file, so a failure of 'git show-index' or the shell
redirection will fail the test.
