With the latest master, 2221a6757161af1905925c405aded9ff470f70d5, "make 
test" now fails; last successful "make test" was mid-week sometime with 
master d25430. This is on a laptop running Suse 9.3.

Trivial question: have you got cvs and cvsps installed?

Can you please try ./t9600 --verbose? Presumably cvsimport is generating
some kind of error message to tell us what's going on.

Unfortunately you attached the interesting part, so I cannot quote it 
here.  Seems that your cvsps does not understand the "-A" option.  So it 
looks like it is too old.

Yes, the changelog indicates that -A was added in 2.1, and he is running
2.0rc1.

We can do something like this, though it feels a bit hack-ish and will
need updated for new cvsps versions (a less lazy or more clever shell
coder than me could do a nice >= version comparator).

t9600: require cvsps 2.1 to perform tests

git-cvsimport won't run at all with less than cvsps 2.1, because it
lacks the -A flag. But there's no point in preventing people who have an
old cvsps from running the full testsuite.

FWIW, the idiom to provide informative messages in test cases is

	say 'skipping cvsimport tests, cvs not found'

This gives a distinguishing color, too.

Ah, I adapted the test from t9400, which uses expect_success. Thanks for
the tip.

It would be Tested-by: in a stricter sense of the word but thanks for
testing.

Jeff, would you want to further amend the patch to use "say" as Hannes
suggested to make it look nicer?

git-cvsimport won't run at all with less than cvsps 2.1, because it
lacks the -A flag. But there's no point in preventing people who have an
old cvsps from running the full testsuite.

I wonder if it is better to grep for ' [-A] ' instead, like:

cvsps_supports_A=$(cvsps -h 2>&1 | sed -ne '/\[-A\]/p')
case "$cvsps_supports_A" in
'')
	say 'skipping cvsimport tests, lacking cvsps that supports -A option'
	test_done
        exit
esac

```

I am not too opposed to that, but I felt that checking the version was a
little bit more future proof. I.e., I have no idea if it is only -A that
we need, but I know that 2.1 works and prior to 2.1 doesn't.

You are right about "we may be depending on what 2.1 has other than
-A".  Will apply as-is.

Thanks, both.

The primary reason I asked about '\[-A\]' was what will happen if
somebody uses 2.2.

Yes, it would be nice to be able to easily check >2.1. GNU expr seems to
handle this ok:

  $ expr 2.2 '>' 2.1
  1
  $ expr 2.0 '>' 2.1
  0

but POSIX seems to mention only integers and string comparison (though
if all are of the form "x.y", string comparison works). I have no idea
how portable this is.

Yeah, but it is the same thing -- we know 2.1 works, we do not know if
2.2 will break things for us ;-)

We'll worry about it when somebody with 2.2 complains.
