If we already have a strbuf, then using write_file_buf is a
little nicer to read (no wondering whether "%s" will eat
your NULs), and it's more efficient (no extra formatting
step).
We don't care about the newline magic of write_file(), as we
have our own multi-line content.

There are several places where we open a file, write some
content from a strbuf, and close it. These can be simplified
with write_file_buf(). As a bonus, many of these did not
catch write problems at close() time.

This gives us compile-time checking of our format strings,
which is a good thing.
I had also hoped it would help with confusing write_file()
and write_file_buf(), since the former's "..." can make it
match the signature of the latter. But given that the buffer
for write_file_buf() is generally not a string literal, the
compiler won't complain unless -Wformat-nonliteral is on,
and that creates a ton of false positives elsewhere in the
code base.
While we're there, let's also give the function a docstring,
which it never had.

There are many callsites which could use write_file, but for
which it is a little awkward because they have a strbuf or
other pointer/len combo. Specifically:
1. write_file() takes a format string, so we have to use
"%s" or "%.*s", which are ugly.
2. Using any form of "%s" does not handle embedded NULs in
the output. That probably doesn't matter for our
call-sites, but it's nicer not to have to worry.
3. It's less efficient; we format into another strbuf
just to do the write. That's probably not measurably
slow for our uses, but it's simply inelegant.
We can fix this by providing a helper to write out the
formatted buffer, and just calling it from write_file().
Note that we don't do the usual "complete with a newline"
that write_file does. If the caller has their own buffer,
there's a reasonable chance they're doing something more
complicated than a single line, and they can call
strbuf_complete_line() themselves.
We could go even further and add strbuf_write_file(), but it
doesn't save much:
- write_file_buf(path, sb.buf, sb.len);
+ strbuf_write_file(&sb, path);
It would also be somewhat asymmetric with strbuf_read_file,
which actually returns errors rather than dying (and the
error handling is most of the benefit of write_file() in the
first place).

This simplifies the code a tiny bit, and provides consistent
error messages with other users of xopen().
While we're here, let's also switch to using O_WRONLY. We
know we're only going to open/write/close the file, so
there's no point in asking for O_RDWR.

There are no callers left of write_file_gently(). Let's drop
it, as it doesn't seem likely for new callers to be added
(since its inception, the only callers who wanted the gentle
form generally just died immediately themselves, and have
since been converted).
While we're there, let's also drop the "int" return from
write_file, as it is never meaningful (in the non-gentle
form, we always either die or return 0).

We use write_file_gently() to do this job currently.
However, if we see an error, we simply complain via
error_errno() and then end up exiting with an error code.
By switching to the non-gentle form, the function will die
for us, with a better error. It is more specific about which
syscall caused the error, and that mentions the
actual filename we're trying to write.
Our exit code for the error case does switch from "1" to
"128", but that's OK; it wasn't a meaningful documented code
(and in fact it was odd that it was a different exit code
than most other error conditions).

write_file() either returns 0 or dies, so there is no point in checking
its return value. The callers of the wrappers write_state_text(),
write_state_count() and write_state_bool() consequently already ignore
their return values. Stop pretending we care and make them void.

Since 9830534 (config --global --edit: create a template
file if needed, 2014-07-25), an edit of the global config
file will try to open() it with O_EXCL, and wants to handle
three cases:
1. We succeeded; the user has no config file, and we
should fill in the default template.
2. We got EEXIST; they have a file already, proceed as usual.
3. We got another error; we should complain.
However, the check for case 1 does "if (fd)", which will
generally _always_ be true (except for the oddball case that
somehow our stdin got closed and opening really did give us
a new descriptor 0).
So in the EEXIST case, we tried to write the default config
anyway! Fortunately, this turns out to be a noop, since we
just end up writing to and closing "-1", which does nothing.
But in case 3, we would fail to notice any other errors, and
just silently continue (given that we don't actually notice
write errors for the template either, it's probably not that
big a deal; we're about to spawn the editor, so it would
notice any problems. But the code is clearly _trying_ to hit
cover this case and failing).
We can fix it easily by using "fd >= 0" for case 1.

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".

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.

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.
