[PATCH] Add test-script for git-tag

[PATCH] Add test-script for git-tag

[Carlos Rica]

These tests are useful to develop the C version for git-tag.sh,
ensuring that the future builtin-tag.c will not break previous
behaviour.

The tests are focused on listing, verifying, deleting and creating
tags, checking always that the correct status value is returned
and everything remains as expected.

In order to verify and create signed tags, a PGP key was also
added, being created this way: gpg --homedir t/t7003 --gen-key
Type DSA and Elgamal, size 2048 bits, no expiration date.
Name and email: C O Mitter <committer@example.com>
No password given, to enable non-interactive operation.

[PATCH] Add test-script for git-tag

[Johannes Schindelin]

From: Carlos Rica <jasampler@gmail.com>

These tests are useful to develop the C version for git-tag.sh,
ensuring that the future builtin-tag.c will not break previous
behaviour.

The tests are focused on listing, verifying, deleting and creating
tags, checking always that the correct status value is returned
and everything remains as expected.

In order to verify and create signed tags, a PGP key was also
added, being created this way: gpg --homedir t/t7003 --gen-key
Type DSA and Elgamal, size 2048 bits, no expiration date.
Name and email: C O Mitter <committer@example.com>
No password given, to enable non-interactive operation.

Signed-off-by: Carlos Rica <jasampler@gmail.com>

	Gmail had a problem with one line. Thus the resend.

It would be better if you _always_ quoted "$1" for my eyes, as
it would let my brain coast over it without thinking.  This does
not matter in practice as we do not allow metacharacters nor
whitespaces in tagnames, but that comes _after_ having to think
about it.

A recent patch made it not to exit with non-zero, but I think
that is probably a bug we might want to fix.

Additional test would be to see git-tag -l "my*" should succeed,
and git-tag -l "my.*" should fail, as the pattern should match
with fnmatch() not regexp().

While it is logically correct to string error conditions with ||
and test inside expect-failure (you are saying "it is a failure
if any of these succeeds"), it needs a bit of brain-twisting to
get what is going on.  But I think this is a valid way to use
expect-failure.

Somehow, "now" gets quite irritating.

I know that there is no such file as 1.1X in the working tree,
but I would feel better if the test protected the ? from the
shell, as in "git tag -l 1.1\? >actual".

I think testing the type directly is more to the point, as in

	test $(git-cat-file -t non-annotated-tag) = commit &&
        test $(git-rev-parse non-annotated-tag) = $(git-rev-parse HEAD)

I would write that as "sed -e '/BEGIN PGP/q'", shorter and more
to the point.

Maybe -0700 deserves a comment --- test_tick always gives time
in that timezone.

You probably would want to also test annotated tags on non
commits (i.e. trees, blobs and tags).

Huh? get_tag_header stores into "expect" file without saying
anything itself, and you redirect that nothingless to the same
file?

> +touch emptyfile

Maybe it's just me being old-fashioned, but I prefer creation of
an empty file be done with:

	: >emptyfile
or just

	>emptyfile

and avoid using "touch".  Some broken systems did not create a
new file with "touch non-existing-file" (I think it was old AIX).

This is just me being curious, but I wonder if this test is safe
to run on an otherwise idle server without moving parts and
keyboard (i.e. lack of sufficient entropy).  I think you made a
prudent choice of not generating a test key in the test script,
by the way.

> +test_expect_success 'verifying a signed tag should succeed' \

Forging the tag at this point and make sure it does not verify
would also be interesting, as in:

	forged=$(git cat-file tag signed-tag |
		sed -e "s/signed-tag/forged-tag/" |
		git mktag) &&
	git tag forged-tag $forged &&
        if git-tag -v forged-tag
        then
        	echo Oops
		false
	else
        	: happy
	fi

Is it necessary to ship random_seed, or is it created as needed
during the test?

[PATCH] Add test-script for git-tag

[Carlos Rica]

These tests are useful to develop the C version for git-tag.sh,
ensuring that the future builtin-tag.c will not break previous
behaviour.

The tests are focused on listing, verifying, deleting and creating
tags, checking always that the correct status value is returned
and everything remains as expected.

In order to verify and create signed tags, a PGP key was also
added, being created this way: gpg --homedir t/t7004 --gen-key
Type DSA and Elgamal, size 2048 bits, no expiration date.
Name and email: C O Mitter <committer@example.com>
No password given, to enable non-interactive operation.

   This patch has the changes that Junio suggested in:
   http://article.gmane.org/gmane.comp.version-control.git/50286

   Since random_seed would be regenerated by gpg when running
   these tests, it is included, to prevent the tests from
   stalling on entropy-weak machines.
