- Don't start tests with 'test $? = 0' to catch preparation done
outside the test_expect_success block.
- Move writing the bogus patch and the expected output into the
appropriate test_expect_success blocks.
- Use the test_must_fail helper instead of manually checking for
non-zero exit code.
- Use the debug-friendly test_path_is_file helper instead of 'test -f'.
- No space after '>'.

Since 920b691 (clone: refuse to clone if --branch
points to bogus ref) we refuse to clone with option
"-b" if the specified branch does not exist in the
(non-empty) upstream. If the upstream repository is empty,
the branch doesn't exist, either. So refuse the clone too.

This makes reinitializing on a .git file repository work.
This is probably the only case that setup_git_env() (via
set_git_dir()) is called on a .git file. Other cases in
setup_git_dir_gently() and enter_repo() both cover .git file case
explicitly because they need to verify the target repo is valid.

The read_mailmap_buf function reads each line of the mailmap
using strchrnul, like:
const char *end = strchrnul(buf, '\n');
unsigned long linelen = end - buf + 1;
But that's off-by-one when we actually hit the NUL byte; our
line does not have a terminator, and so is only "end - buf"
bytes long. As a result, when we subtract the linelen from
the total len, we end up with (unsigned long)-1 bytes left
in the buffer, and we start reading random junk from memory.
We could fix it with:
unsigned long linelen = end - buf + !!*end;
but let's take a step back for a moment. It's questionable
in the first place for a function that takes a buffer and
length to be using strchrnul. But it works because we only
have one caller (and are only likely to ever have this one),
which is handing us data from read_sha1_file. Which means
that it's always NUL-terminated.
Instead of tightening the assumptions to make the
buffer/length pair work for a caller that doesn't actually
exist, let's let loosen the assumptions to what the real
caller has: a modifiable, NUL-terminated string.
This makes the code simpler and shorter (because we don't
have to correlate strchrnul with the length calculation),
correct (because the code with the off-by-one just goes
away), and more efficient (we can drop the extra allocation
we needed to create NUL-terminated strings for each line,
and just terminate in place).

The 'todo' sheet for interactive rebase shows abbreviated SHA-1's and
then performs its operations upon those shortened values. This can lead
to an abort if the SHA-1 of a reworded or edited commit is no longer
unique within the abbreviated SHA-1 space and a subsequent SHA-1 in the
todo list has the same abbreviated value.
For example:
edit f00dfad first
pick badbeef second
If, after editing, the new SHA-1 of "first" also has prefix badbeef,
then the subsequent 'pick badbeef second' will fail since badbeef is no
longer a unique SHA-1 abbreviation:
error: short SHA1 badbeef is ambiguous.
fatal: Needed a single revision
Invalid commit name: badbeef
Fix this problem by expanding the SHA-1's in the todo list before
performing the operations.

As its very first action, t3404 installs (via set_fake_editor) a
specialized $EDITOR which simplifies automated 'rebase -i' testing. Many
tests rely upon this setting, thus tests which need a different editor
must take extra care upon completion to restore $EDITOR in order to
avoid breaking following tests. This places extra burden upon such tests
and requires that they undesirably have extra knowledge about
surrounding tests. Ease this burden by having each test install the
$EDITOR it requires, rather than relying upon a global setting.

fetch_pack() can remove .git/shallow file when a shallow repository
becomes a full one again. This behavior is triggered incorrectly when
tags are also fetched because fetch_pack() will be called twice. At
the first fetch_pack() call:
- shallow_lock is set up
- alternate_shallow_file points to shallow_lock.filename, which is
"shallow.lock"
- commit_lock_file is called, which sets shallow_lock.filename to "".
alternate_shallow_file also becomes "" because it points to the
same memory.
At the second call, setup_alternate_shallow() is not called and
alternate_shallow_file remains "". It's mistaken as unshallow case and
.git/shallow is removed. The end result is a broken repository.
Fix this by always initializing alternate_shallow_file when
fetch_pack() is called. As an extra measure, check if args->depth > 0
before commit/rollback shallow file.

Checking out 2GB or more through an external filter (see test) fails
on Mac OS X 10.8.4 (12E55) for a 64-bit executable with:
error: read from external filter cat failed
error: cannot feed the input to external filter cat
error: cat died of signal 13
error: external filter cat failed 141
error: external filter cat failed
The reason is that read() immediately returns with EINVAL when asked
to read more than 2GB. According to POSIX [1], if the value of
nbyte passed to read() is greater than SSIZE_MAX, the result is
implementation-defined. The write function has the same restriction
[2]. Since OS X still supports running 32-bit executables, the
32-bit limit (SSIZE_MAX = INT_MAX = 2GB - 1) seems to be also
imposed on 64-bit executables under certain conditions. For write,
the problem has been addressed earlier [6c642a].
Address the problem for read() and write() differently, by limiting
size of IO chunks unconditionally on all platforms in xread() and
xwrite(). Large chunks only cause problems, like causing latencies
when killing the process, even if OS X was not buggy. Doing IO in
reasonably sized smaller chunks should have no negative impact on
performance.
The compat wrapper clipped_write() introduced earlier [6c642a] is
not needed anymore. It will be reverted in a separate commit. The
new test catches read and write problems.
Note that 'git add' exits with 0 even if it prints filtering errors
to stderr. The test, therefore, checks stderr. 'git add' should
probably be changed (sometime in another commit) to exit with
nonzero if filtering fails. The test could then be changed to use
test_must_fail.

Git fails due to a segmentation fault if a submodule path is empty.
Here is an example .gitmodules that will cause a segmentation fault:
[submodule "foo-module"]
path
url = http://host/repo.git
$ git status
Segmentation fault (core dumped)
This is because the parsing of "submodule.*.path" is not prepared to
see a value-less "true" and assumes that the value is always
non-NULL (parsing of "ignore" has the same problem).
Fix it by checking the NULL-ness of value and complain with
config_error_nonbool().

This is an attempt to reproduce a problem reported for a third-party
custom "connect" remote helper. The conjecture is that sometimes
"git fetch" wants to make two connections (one for the primary
transfer with 'follow-tags' option set, and then after noticing that
some tags are not packed because the primary transfer did not have
to send any commit that is pointed by them, another to explicitly
ask for the missing tags), and their "connect" helper is not called
in the second request, breaking the "fetch" as a whole.
Unfortunately this test script does not trigger the alleged failure
and happily passes when talking to upload-pack from git-core (see
patch 5/5 for details).

Some implementations of 'echo' (e.g. dash's built-in) interpret
backslash sequences in their arguments.
This triggered at least one bug: the error message of "rebase -i" was
turning \t in commit messages into actual tabulations. There may be
others.
Using "printf '%s\n'" instead avoids this bad behavior, and is the form
used by the "say" function.

Sub-test 42 of t8001 and t8002 ("blame -L :literal") fails on NetBSD
with the following verbose output:

Author F (expected 4, attributed 3) bad
Author G (expected 1, attributed 1) good
This is not caused by different behaviour of git blame or annotate on
that platform, but by different test input, in turn caused by a sed
command that forgets to add a newline on NetBSD. Here's the diff of the
commit that adds "goodbye" to hello.c, for Linux:
@@ -1,4 +1,5 @@
int main(int argc, const char *argv[])

The following patch gets rid of the extra TAB at the beginning, but
more importantly adds the missing newline at the end in a (hopefully)

The test file that the UTF-16 rejection test looks for is missing, but this went
unnoticed because the test is expected to fail anyway; as a consequence, the

because the test file contains a NUL byte. Fix this by including a sample text
file containing a commit message encoded in UTF-16.

The reflog walking logic (git log -g) replaces the true parent list
with the preceding commit in the reflog. This results in bogus commit
diffs when combined with options such as -p; the diff is against the
reflog predecessor, not the parent of the commit.
Save the true parents on the side, extending the functions from the
previous commit. The diff logic picks them up and uses them to show
the correct diffs.
We do have to be somewhat careful about repeated calling of
save_parents(), since the reflog may list a commit more than once. We
now store (commit_list*)-1 to distinguish the "not saved yet" and
"root commit" cases. This lets us preserve an empty parent list even
if save_parents() is repeatedly called.

When using pathspec filtering in combination with diff-based log
output, parent simplification happens before the diff is computed.
The diff is therefore against the *simplified* parents.
This works okay, arguably by accident, in the normal case:
simplification reduces to one parent as long as the commit is TREESAME
to it. So the simplified parent of any given commit must have the
same tree contents on the filtered paths as its true (unfiltered)
parent.
However, --full-diff breaks this guarantee, and indeed gives pretty
spectacular results when comparing the output of
git log --graph --stat ...
git log --graph --full-diff --stat ...
(--graph internally kicks in parent simplification, much like
--parents).
To fix it, store a copy of the parent list before simplification (in a
slab) whenever --full-diff is in effect. Then use the stored parents
instead of the simplified ones in the commit display code paths. The
latter do not actually check for --full-diff to avoid duplicated code;
they just grab the original parents if save_parents() has not been
called for this revision walk.
For ordinary commits it should be obvious that this is the right thing
to do.
Merge commits are a bit subtle. Observe that with default
simplification, merge simplification is an all-or-nothing decision:
either the merge is TREESAME to one parent and disappears, or it is
different from all parents and the parent list remains intact.
Redundant parents are not pruned, so the existing code also shows them
as a merge.
So if we do show a merge commit, the parent list just consists of the
rewrite result on each parent. Running, e.g., --cc on this in
--full-diff mode is not very useful: if any commits were skipped, some
hunks will disagree with all sides of the merge (with one side,
because commits were skipped; with the others, because they didn't
have those changes in the first place). This triggers --cc showing
these hunks spuriously.
Therefore I believe that even for merge commits it is better to show
the diffs wrt. the original parents.
