[PATCH 03/10] fetch tests: use "local", &&-chaining, style etc.

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

 



Make use of &&-chaining, the "local" keyword, the more idiomatic "test
-z" over comparison against "" etc. in the
"test_configured_prune_type()" function.

Let's also move the wrapper function to below the function itself. In
e1790f9245f (fetch tests: fetch <url> <spec> as well as fetch
[<remote>], 2018-02-09) placed in there to minimize the diff
size. While it's not incorrect to define these in this order (this
isn't C), it's less confusing this way.
