2019-06-21env--helper: new undocumented builtin wrapping git_env_*()Libravatar Ævar Arnfjörð Bjarmason1-0/+95
We have many GIT_TEST_* variables that accept a <boolean> because they're implemented in C, and then some that take <non-empty?> because they're implemented at least partially in shellscript. Add a helper that wraps git_env_bool() and git_env_ulong() as the first step in fixing this. This isn't being added as a test-tool mode because some of these are used outside the test suite. Part of what this tool does can be done via a trick with "git config" added in 83d842dc8c ("tests: turn on network daemon tests by default", 2014-02-10) for test_tristate(), i.e.: git -c magic.variable="$1" config --bool magic.variable 2>/dev/null But as subsequent changes will show being able to pass along the default value makes all the difference, and we'll be able to replace test_tristate() itself with that. The --type=bool option will be used by subsequent patches, but not --type=ulong. I figured it was easy enough to add it & test for it so I left it in so we'd have wrappers for both git_env_*() functions, and to have a template to make it obvious how we'd add --type=int etc. if it's needed in the future.
