hashcpy with null_sha1 as the source is equivalent to hashclr. In
addition to being simpler, using hashclr may give the compiler a chance
to optimize better. Convert instances of hashcpy with the source
argument of null_sha1 to hashclr.
This transformation was implemented using the following semantic patch:
@@
expression E1;
@@
-hashcpy(E1, null_sha1);
+hashclr(E1);

Coccinelle (http://coccinelle.lip6.fr/) is a program which performs
mechanical transformations on C programs using semantic patches. These
semantic patches can be used to implement automatic refactoring and
maintenance tasks.
Add a set of basic semantic patches to convert common patterns related
to the struct object_id transformation, as well as a README.

This function works just like sha1_to_hex_r, except that it takes a

reports that a change to add a new "function" with common ending
with the existing one at the end of the file is shown like this:
def foo
do_foo_stuff()
+ common_ending()
+end
+
+def bar
+ do_bar_stuff()
+
common_ending()
end
when the new heuristic is in use. In reality, the change is to add
the blank line before "def bar" and everything below, which is what
the code without the new heuristic shows.
Disable the heuristics by default, and resurrect the documentation
for the option and the configuration variables, while clearly
marking the feature as still experimental.

When we run scripted Porcelains, "git" potty has set up the $PATH by
prepending $GIT_EXEC_PATH, the path given by "git --exec-path=$there
$cmd", etc. already. Because of this, scripted Porcelains can
dot-source shell script library like git-sh-setup with simple dot
without specifying any path.
t2300 however dot-sources git-sh-setup without adjusting $PATH like
the real "git" potty does. This has not been a problem so far, but
once git-sh-setup wants to rely on the $PATH adjustment, just like
any scripted Porcelains already do, it would become one. It cannot
for example dot-source another shell library without specifying the
full path to it by prefixing $(git --exec-path).

In t5500::check_prot_host_port_path(), diagport is not a variable
used elsewhere and the function is not recursively called so this
can simply lose the "local", which may not be supported by shell
(besides, the function liberally clobbers other variables without
making them "local").
t7403::reset_submodule_urls() overrides the "root" variable used
in the test framework for no good reason; its use is not about
temporarily relocating where the test repositories are created.
This assignment can be made not to clobber the variable by moving
them into the subshells it already uses. Its value is always
$TRASH_DIRECTORY, so we could use it instead there, and this
function that is called only once and its two subshells may not be
necessary (instead, the caller can use "git -C $there config" and
set a value that is derived from $TRASH_DIRECTORY), but this is a
minimum fix that is needed to lose "local".

In 48308681 (2016-02-29, git submodule update: have a dedicated helper
for cloning), the helper communicated errors back only via exit code,
and dance with printing '#unmatched' in case of error was left to
git-submodule.sh as it uses the output of the helper and pipes it into
shell commands. This change makes the helper consistent by never
printing '#unmatched' in the helper but always handling these piping
issues in the actual shell script.

This does not change the behavior, but allows the user to tweak
DEVELOPER_CFLAGS on the command-line or in a config.mak* file if
needed.
This also makes the code somewhat cleaner as it follows the pattern
<initialisation of variables>
<include statements>
<actual build logic>
by specifying which flags to activate in the first part, and actually
activating them in the last one.

The one-shot environment variable syntax:
FOO=BAR some-program
is unportable when some-program is actually a shell
function, like test_must_fail (on some shells FOO remains
set after the function returns, and on others it does not).
We sometimes get around this by using env, like:
test_must_fail env FOO=BAR some-program
But that only works because test_must_fail's arguments are
themselves a command which can be run. You can't run:
env FOO=BAR test_must_fail some-program
because env does not know about our shell functions. So
there is no equivalent for test_commit, for example, and one
must resort to:
(
FOO=BAR
export FOO
test_commit
)
which is a bit verbose. Let's add a version of "env" that
works _inside_ the shell, by creating a subshell, exporting
variables from its argument list, and running the command.
Its use is demonstrated on a currently-unportable case in
t4014.

Running tests with '-x' option to trace the individual command
executions is a useful way to debug test scripts, but some tests
that capture the standard error stream and check what the command
said can be broken with the trace output mixed in. When running
our tests under "bash", however, we can redirect the trace output
to another file descriptor to keep the standard error of programs
being tested intact.

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag. It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."
* js/name-rev-use-oldest-ref:
name-rev: include taggerdate in considering the best name

Interactive rebase uses 'git cherry-pick' and 'git merge' to replay
commits. Both invoke the 'rerere' machinery when they fail due to merge
conflicts. Note that all code paths with these two commands also invoke
the shell function die_with_patch when the commands fail.
Since commit 629716d2 ("rerere: do use multiple variants") the second
operation of the rerere machinery can be observed by a duplicated
message "Recorded preimage for 'file'". This second operation records
the same preimage as the first one and, hence, only wastes cycles.
Remove the 'git rerere' invocation from die_with_patch.
Shell function die_with_patch can be called after the failure of
"git commit", too, which also calls into the rerere machinery, but it
does so only after a successful commit to record the resolution.
Therefore, it is wrong to call 'git rerere' from die_with_patch after
"git commit" fails.
