submodule: stop sanitizing config options
The point of having a whitelist of command-line config
options to pass to submodules was two-fold:
1. It prevented obvious nonsense like using core.worktree
for multiple repos.
2. It could prevent surprise when the user did not mean
for the options to leak to the submodules (e.g.,
http.sslverify=false).
For case 1, the answer is mostly "if it hurts, don't do
that". For case 2, we can note that any such example has a
matching inverted surprise (e.g., a user who meant
http.sslverify=true to apply everywhere, but it didn't).
So this whitelist is probably not giving us any benefit, and
is already creating a hassle as people propose things to put
on it. Let's just drop it entirely.
Note that we still need to keep a special code path for
"prepare the submodule environment", because we still have
to take care to pass through $GIT_CONFIG_PARAMETERS (and
block the rest of the repo-specific environment variables).
We can do this easily from within the submodule shell
script, which lets us drop the submodule--helper option
entirely (and it's OK to do so because as a "--" program, it
is entirely a private implementation detail).

submodule: use prepare_submodule_repo_env consistently
Before
14111fc (git: submodule honor -c credential.* from
command line, 2016-02-29), it was sufficient for code which
spawned a process in a submodule to just set the child
process's "env" field to "local_repo_env" to clear the
environment of any repo-specific variables.
That commit introduced a more complicated procedure, in
which we clear most variables but allow through sanitized
config. For C code, we used that procedure only for cloning,
but not for any of the programs spawned by submodule.c. As a
result, things like "git fetch --recurse-submodules" behave
differently than "git clone --recursive"; the former will
not pass through the sanitized config.
We can fix this by using prepare_submodule_repo_env()
everywhere in submodule.c.

submodule: export sanitized GIT_CONFIG_PARAMETERS
Commit

the environment for a submodule. However, it failed to

We didn't catch this in our initial tests because we checked

git_config_push_parameter: handle empty GIT_CONFIG_PARAMETERS
The "git -c var=value" option stuffs the config value into
$GIT_CONFIG_PARAMETERS, so that sub-processes can see it.
When the config is later read via git_config() or similar,
we parse it back out of that variable. The parsing end is a
little bit picky; it assumes that each entry was generated
with sq_quote_buf(), and that there is no extraneous
whitespace.
On the generating end, we are careful to append to an
existing $GIT_CONFIG_PARAMETERS variable if it exists.
However, our test for "should we add a space separator" is
too liberal: it will add one even if the environment
variable exists but is empty. As a result, you might end up
with:
GIT_CONFIG_PARAMETERS=" 'core.foo=bar'"
which the parser will choke on.
This was hard to trigger in older versions of git, since we
only set the variable when we had something to put into it
(though you could certainly trigger it manually). But since
14111fc (git: submodule honor -c credential.* from command
line, 2016-02-29), the submodule code will unconditionally
put the $GIT_CONFIG_PARAMETERS variable into the environment
of any operation in the submodule, whether it is empty or
not. So any of those operations which themselves use "git
-c" will generate the unparseable value and fail.
We can easily fix it by catching this case on the generating
side. While we're adding a test, let's also check that
multiple layers of "git -c" work, which was previously not
tested at all.

git: submodule honor -c credential.* from command line
Due to the way that the git-submodule code works, it clears all local
git environment variables before entering submodules. This is normally
a good thing since we want to clear settings such as GIT_WORKTREE and
other variables which would affect the operation of submodule commands.
However, GIT_CONFIG_PARAMETERS is special, and we actually do want to
preserve these settings. However, we do not want to preserve all
configuration as many things should be left specific to the parent
project.
Add a git submodule--helper function, sanitize-config, which shall be
used to sanitize GIT_CONFIG_PARAMETERS, removing all key/value pairs
except a small subset that are known to be safe and necessary.
Replace all the calls to clear_local_git_env with a wrapped function
that filters GIT_CONFIG_PARAMETERS using the new helper and then
restores it to the filtered subset after clearing the rest of the

list-objects: pass full pathname to callbacks
When we find a blob at "a/b/c", we currently pass this to
our show_object_fn callbacks as two components: "a/b/" and
"c". Callbacks which want the full value then call
path_name(), which concatenates the two. But this is an
inefficient interface; the path is a strbuf, and we could
simply append "c" to it temporarily, then roll back the
length, without creating a new copy.
So we could improve this by teaching the callsites of
path_name() this trick (and there are only 3). But we can
also notice that no callback actually cares about the
broken-down representation, and simply pass each callback
the full path "a/b/c" as a string. The callback code becomes
even simpler, then, as we do not have to worry about freeing
an allocated buffer, nor rolling back our modification to
the strbuf.
This is theoretically less efficient, as some callbacks
would not bother to format the final path component. But in
practice this is not measurable. Since we use the same
strbuf over and over, our work to grow it is amortized, and
we really only pay to memcpy a few bytes.

list-objects: convert name_path to a strbuf
The "struct name_path" data is examined in only two places:
we generate it in process_tree(), and we convert it to a
single string in path_name(). Everyone else just passes it
through to those functions.
We can further note that process_tree() already keeps a
single strbuf with the leading tree path, for use with
tree_entry_interesting().
Instead of building a separate name_path linked list, let's
just use the one we already build in "base". This reduces
the amount of code (especially tricky code in path_name()
which did not check for integer overflows caused by deep
or large pathnames).
It is also more efficient in some instances. Any time we
were using tree_entry_interesting, we were building up the
strbuf anyway, so this is an immediate and obvious win
there. In cases where we were not, we trade off storing
"pathname/" in a strbuf on the heap for each level of the
path, instead of two pointers and an int on the stack (with
one pointer into the tree object). On a 64-bit system, the
latter is 20 bytes; so if path components are less than that
on average, this has lower peak memory usage. In practice
it probably doesn't matter either way; we are already
holding in memory all of the tree objects leading up to each
pathname, and for normal-depth pathnames, we are only
talking about hundreds of bytes.
This patch leaves "struct name_path" as a thin wrapper
around the strbuf, to avoid disrupting callbacks. We should
fix them, but leaving it out makes this diff easier to view.

We'd like to eventually get rid of name_path entirely in
favor of a single buffer, and dropping this custom printing
code is part of that. As a first step, let's use path_name()
to format the list into a single buffer, and print that.

This usage came in
aa1dbc9 (Update http-push functionality,

either). But we stopped using that function in

storing just the objects themselves.
Moreover, the generation of the name in process_tree() is
buggy. It sticks "name" onto the end of the name_path linked
list, and then passes it down again as it recurses (instead
of "entry.path"). So it's a good thing this was unused, as

get_sha1: don't die() on bogus search strings
The get_sha1() function generally returns an error code
rather than dying, and we sometimes speculatively call it
with something that may be a revision or a pathspec, in
order to see which one it might be.
If it sees a bogus ":/" search string, though, it complains,
without giving the caller the opportunity to recover. We can
demonstrate this in t6133 by looking for ":/*.t", which
should mean "*.t at the root of the tree", but instead dies
because of the invalid regex (the "*" has nothing to operate
on).
We can fix this by returning an error rather than calling
die(). Unfortunately, the tradeoff is that the error message
is slightly worse in cases where we _do_ know we have a rev.
E.g., running "git log ':/*.t' --" before yielded:
fatal: Invalid search pattern: *.t
and now we get only:
fatal: bad revision ':/*.t'
There's not a simple way to fix this short of passing a
"quiet" flag all the way through the get_sha1() stack.

check_filename: tighten dwim-wildcard ambiguity
When specifying both revisions and pathnames, we allow
"<rev> -- <pathspec>" to be spelled without the "--" as long
as it is not ambiguous. The original logic was something
like:
1. Resolve each item with get_sha1(). If successful,
we know it can be a <rev>. Verify that it _isn't_ a
filename, using verify_non_filename(), and complain of
ambiguity otherwise.
2. If get_sha1() didn't succeed, make sure that it _is_
a file, using verify_filename(). If not, complain
that it is neither a <rev> nor a <pathspec>.
Both verify_filename() and verify_non_filename() rely on
check_filename(), which definitely said "yes, this is a
file" or "no, it is not" using lstat().
Commit
28fcc0b (pathspec: avoid the need of "--" when
wildcard is used, 2015-05-02) introduced a convenience
feature: check_filename() will consider anything with
wildcard meta-characters as a possible filename, without
even checking the filesystem.
This works well for case 2. For such a wildcard, we would
previously have died and said "it is neither". Post-
28fcc0b,
we assume it's a pathspec and proceed.
But it makes some instances of case 1 worse. We may have an
extended sha1 expression that contains meta-characters
(e.g., "HEAD^{/foo.*bar}"), and we now complain that it's
also a filename, due to the wildcard characters (even though
that wildcard would not match anything in the filesystem).
One solution would be to actually expand the pathname and
see if it matches anything on the filesystem. But that's
potentially expensive, and we do not have to be so rigorous
for this DWIM magic (if you want rigor, use "--").
Instead, we can just use different rules for cases 1 and 2.
When we know something is a rev, we will complain only if it
meets a much higher standard for "this is also a file";
namely that it actually exists in the filesystem. Case 2
remains the same: we use the looser "it could be a filename"
standard introduced by
28fcc0b.
We can accomplish this by pulling the wildcard logic out of
check_filename() and putting it into verify_filename(). Its
partner verify_non_filename() does not need a change, since
check_filename() goes back to implementing the "higher
standard".
Besides these two callers of check_filename(), there is one
other: git-checkout does a similar DWIM itself. It hits this
code path only after get_sha1() has returned failure, making
it case 2, which gets the special wildcard treatment.
Note that we drop the tests in t2019 in favor of a more
complete set in t6133. t2019 was not the right place for
them (it's about refname ambiguity, not dwim parsing
ambiguity), and the second test explicitly checked for the
opposite result of the case we are fixing here (which didn't
really make any sense; as shown by the test_must_fail in the
test, it would only serve to annoy people).

checkout: reorder check_filename conditional
If we have a "--" flag, we should not be doing DWIM magic
based on whether arguments can be filenames. Reorder the
conditional to avoid the check_filename() call entirely in
this case. The outcome is the same, but the short-circuit
makes the dependency more clear.
