The current logic makes it hard to see what gets put onto
the command line in which cases. Pulling out a helper
function lets us see that we have two sets of file data, and
the second set either uses the original name, or the "other"
renamed/copy name.

Whether we have diff_filespecs to give to the diff command
or not, we always are going to run the program and pass it
the pathname. Let's pull that duplicated part out of the
conditional to make it more obvious.

This fflush was added in d5535ec (Use run_command() to spawn
external diff programs instead of fork/exec., 2007-10-19),
because flushing buffers before forking is a good habit.
But later, 7d0b18a (Add output flushing before fork(),
2008-08-04) added it to the generic run-command interface,
meaning that our flush here is redundant.

When the external diff reports an error, we try to clean up
and die. However, we can make this process a bit simpler:
1. We do not need to bother freeing memory, since we are
about to exit. Nor do we need to clean up our
tempfiles, since the atexit() handler will do it for
us. So we can die as soon as we see the error.
3. We can just call die() rather than fprintf/exit. This
does technically change our exit code, but the exit
code of "1" is not meaningful here. In fact, it is
probably wrong, since "1" from diff usually means
"completed successfully, but there were differences".
And while we're there, we can mark the error message for
translation, and drop the full stop at the end to make it
more like our other messages.

We currently use static buffers and a static array for
formatting the environment passed to the external diff.
There's nothing wrong in the code, but it is much easier to
verify that it is correct if we use a dynamic argv_array.

We currently generate the command-line for the external
command using a fixed-length array of size 10. But if there
is a rename, we actually need 11 elements (10 items, plus a
NULL), and end up writing a random NULL onto the stack.
Rather than bump the limit, let's just use an argv_array, which
makes this sort of error impossible.

We need to consider that a remote-tracking branch may match more than
one rhs of a fetch refspec. In such a case, it is not enough to stop at
the first match but look at all of the matches in order to determine
whether a head is stale.
To this goal, introduce a variant of query_refspecs which returns all of
the matching refspecs and loop over those answers to check for
staleness.

When a remote has multiple fetch refspecs and these overlap in the
target namespace, fetch may prune a remote-tracking branch which still
exists in the remote. The test uses a popular form of this, by putting
pull requests as stored in a popular hosting platform alongside "real"
remote-tracking branches.
The fetch command makes a decision of whether to prune based
on the first matching refspec, which in this case is insufficient, as it
covers the pull request names. This pair of refspecs does work as
expected if the more "specific" refspec is the first in the list.

One of the tests in t4212 checks our behavior when we feed
gmtime a date so far in the future that it gives up and
returns NULL. Some implementations, like AIX, may actually
just provide us a bogus result instead.
It's not worth it for us to come up with heuristics that
guess whether the return value is sensible or not. On good
platforms where gmtime reports the problem to us with NULL,
we will print the epoch value. On bad platforms, we will
print garbage. But our test should be written for the
lowest common denominator so that it passes everywhere.

Most gmtime implementations return a NULL value when they
encounter an error (and this behavior is specified by ANSI C
and POSIX). FreeBSD's implementation, however, will simply
leave the "struct tm" untouched. Let's also recognize this
and convert it to a NULL (with this patch, t4212 should pass
on FreeBSD).

diff_opt_parse() returns the number of options parsed, or often
returns error() which is defined to return -1. Yes, return value of
0 is "I did not process that option at all", which should cause the
caller to say that, but negative return should not be forgotten.
This bug caused "diff --no-index" to infinitely show the same error
message because the returned value was used to decrement the loop
control variable, e.g.
$ git diff --no-index --color=words a b
error: option `color' expects "always", "auto", or "never"
error: option `color' expects "always", "auto", or "never"
...
Instead, make it act like so:
$ git diff --no-index --color=words a b
error: option `color' expects "always", "auto", or "never"
fatal: invalid diff option/value: --color=words

"git status --branch --porcelain" displays the status of the branch

Use hardcoded strings when --porcelain is used, but keep the gettext
translation for "git status --short" which is essentially the same, but
meant to be read by a human.

When commit a88c915 (mv: move submodules using a gitfile, 2013-07-30)
added the submodule_gitfile array, it was not added to the block that
enlarges the arrays when we are moving a directory so that we do not
have to worry about it being a directory when we perform the actual
move. After this, the loop continues over the enlarged set of sources.
Since we assume that submodule_gitfile has size argc, if any of the
items in the source directory are submodules we are guaranteed to write
beyond the end of submodule_gitfile.
Fix this by realloc'ing submodule_gitfile at the same time as the other
arrays.

| | | | | | | |
When lib-terminal.sh is sourced by a test script, we
immediately set up the TTY prerequisite. We do so inside a
test_expect_success, because that nicely isolates any
generated output.
However, this early test can interfere with a script that
later wants to skip all tests (e.g., t5541 then goes on to
set up the httpd server, and wants to skip_all if that
fails). TAP output doesn't let us skip everything after we
have already run at least one test.
We could fix this by reordering the inclusion of
lib-terminal.sh in t5541 to go after the httpd setup. That
solves this case, but we might eventually hit a case with
circular dependencies, where either lib-*.sh include might
want to skip_all after the other has run a test. So
instead, let's just remove the ordering constraint entirely
by doing the setup inside a test_lazy_prereq construct,
rather than in a regular test. We never cared about the
test outcome anyway (it was written to always succeed).
Note that in addition to setting up the prerequisite, the
current test also defines test_terminal. Since we can't
affect the environment from a lazy_prereq, we have to hoist
that out. We previously depended on it _not_ being defined
when the TTY prereq isn't set as a way to ensure that tests
properly declare their dependency on TTY. However, we still
cover the case (see the in-code comment for details).

In some places we "echo" a string that comes from a commit log
message, which may have a backslash sequence that is interpreted by
the command (POSIX.1 allows this), most notably "dash"'s built-in
'echo'.
A commit message which contains the string '\n' (or ends with the
string '\c') may result in a garbage line in the todo list of an
interactive rebase which causes the rebase to fail.
To reproduce the behavior (with dash as /bin/sh):
mkdir test && cd test && git init
echo 1 >foo && git add foo
git commit -m"this commit message ends with '\n'"
echo 2 >foo && git commit -a --fixup HEAD
git rebase -i --autosquash --root
Now the editor opens with garbage in line 3 which has to be
removed or the rebase fails.
