The first set of tests in t5300 goes back to 2005, and doesn't use some
of our customary style and tools these days. In preparation for touching
them, let's modernize a few things:
- titles go on the line with test_expect_success, with a hanging
open-quote to start the test body
- test bodies should be indented with tabs
- opening braces for shell blocks in &&-chains go on their own line
- no space between redirect operators and files (">foo", not "> foo")
- avoid doing work outside of test blocks; in this case, we can stick
the setup of ".git2" into the appropriate blocks
- avoid modifying and then cleaning up the environment or current
directory by using subshells and "git -C"
- this test does a curious thing when testing the unpacking: it sets
GIT_OBJECT_DIRECTORY, and then does a "git init" in the _original_
directory, creating a weird mixed situation. Instead, it's much
simpler to just "git init --bare" a new repository to unpack into,
and check the results there. I renamed this "git2" instead of
".git2" to make it more clear it's a separate repo.
- we can observe that the bodies of the no-delta, ref_delta, and
ofs_delta cases are all virtually identical except for the pack
creation, and factor out shared helper functions. I collapsed "do
the unpack" and "check the results of the unpack" into a single
test, since that makes the expected lifetime of the "git2" temporary
directory more clear (that also lets us use test_when_finished to
clean it up). This does make the "-v" output slightly less useful,
but the improvement in reading the actual test code makes it worth
it.
- I dropped the "pwd" calls from some tests. These don't do anything
functional, and I suspect may have been an aid for debugging when
the script was more cavalier about leaving the working directory
changed between tests.
