When we added generic end-of-options support in 51b4594b40
(parse-options: allow --end-of-options as a synonym for "--",
2019-08-06), we made them true synonyms. They both stop option parsing,
and they are both returned in the resulting argv if the KEEP_DASHDASH
flag is used.
The hope was that this would work for all callers:
- most generic callers would not pass KEEP_DASHDASH, and so would just
do the right thing (stop parsing there) without needing to know
anything more.
- callers with KEEP_DASHDASH were generally going to rely on
setup_revisions(), which knew to handle --end-of-options specially
But that turned out miss quite a few cases that pass KEEP_DASHDASH but
do their own manual parsing. For example, "git reset", "git checkout",
and so on want pass KEEP_DASHDASH so they can support:
git reset $revs -- $paths
but of course aren't going to actually do a traversal, so they don't
call setup_revisions(). And those cases currently get confused by
--end-of-options being left in place, like:
$ git reset --end-of-options HEAD
fatal: option '--end-of-options' must come before non-option arguments
We could teach each of these callers to handle the leftover option
explicitly. But let's try to be a bit more clever and see if we can
solve it centrally in parse-options.c.
The bogus assumption here is that KEEP_DASHDASH tells us the caller
wants to see --end-of-options in the result. But really, the callers
which need to know that --end-of-options was reached are those that may
potentially parse more options from argv. In other words, those that
pass the KEEP_UNKNOWN_OPT flag.
If such a caller is aware of --end-of-options (e.g., because they call
setup_revisions() with the result), then this will continue to do the
right thing, treating anything after --end-of-options as a non-option.
And if the caller is not aware of --end-of-options, they are better off
keeping it intact, because either:
1. They are just passing the options along to somebody else anyway, in
which case that somebody would need to know about the
--end-of-options marker.
2. They are going to parse the remainder themselves, at which point
choking on --end-of-options is much better than having it silently
removed. The point is to avoid option injection from untrusted
command line arguments, and bailing is better than quietly treating
the untrusted argument as an option.
This fixes bugs with --end-of-options across several commands, but I've
focused on two in particular here:
- t7102 confirms that "git reset --end-of-options --foo" now works.
This checks two things. One, that we no longer barf on
"--end-of-options" itself (which previously we did, even if the rev
was something vanilla like "HEAD" instead of "--foo"). And two, that
we correctly treat "--foo" as a revision rather than an option.
This fix applies to any other cases which pass KEEP_DASHDASH but not
KEEP_UNKNOWN_OPT, like "git checkout", "git check-attr", "git grep",
etc, which would previously choke on "--end-of-options".
- t9350 shows the opposite case: fast-export passed KEEP_UNKNOWN_OPT
but not KEEP_DASHDASH, but then passed the result on to
setup_revisions(). So it never saw --end-of-options, and would
erroneously parse "fast-export --end-of-options --foo" as having a
"--foo" option. This is now fixed.
Note that this does shut the door for callers which want to know if we
hit end-of-options, but don't otherwise need to keep unknown opts. The
obvious thing here is feeding it to the DWIM verify_filename()
machinery. And indeed, this is a problem even for commands which do
understand --end-of-options already. For example, without this patch,
you get:
$ git log --end-of-options --foo
fatal: option '--foo' must come before non-option arguments
because we refuse to accept "--foo" as a filename (because it starts
with a dash) even though we could know that we saw end-of-options. The
verify_filename() function simply doesn't accept this extra information.
So that is the status quo, and this patch doubles down further on that.
Commands like "git reset" have the same problem, but they won't even
know that parse-options saw --end-of-options! So even if we fixed
verify_filename(), they wouldn't have anything to pass to it.
But in practice I don't think this is a big deal. If you are being
careful enough to use --end-of-options, then you should also be using
"--" to disambiguate and avoid the DWIM behavior in the first place. In
other words, doing:
git log --end-of-options --this-is-a-rev -- --this-is-a-path
works correctly, and will continue to do so. And likewise, with this
patch now:
git reset --end-of-options --this-is-a-rev -- --this-is-a-path
will work, as well.
