[PATCH 4/4] tests: get rid of $_x05 from the test suite

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Remove the last users of the $_x05 variable from the tests. It turns
out that all of these tests can be rewritten unambiguously to simply
use [0-9a-f]* instead.

In the case of the tree matching we're relying on there being a <TAB>
after the SHA (but a space between the modes and type), then in some
of the other tests here that an abbreviated SHA is at the start of the
line, etc.
