Since by default git is installed such that most of the dashed-form
commands are not in a user's default PATH, my thought was that
it would make sense for the test suite to mimick that environment
as much as possible. This could detect regressions in any
installed/tested git script that erroneously assumes the dashed
form commands are in the PATH, not just git-cvsserver.
I can think of ways it could be made smaller, but they seem uglier than
the current patch to me:
1. Perhaps just list the executables for the fake bin directory
separately, but then it is all too easy for the list to get out of sync
with what the final install environment will be.
2. Perhaps strip off the $X's (.exe on windows; currently empty
elsewhere) from the words of the existing variables, in the rule
for building the "fake bin" directory. But generally I'ld rather
not assume that pattern-matching replacement of
$X's will never conflict with a part of a script name.
3. Perhaps just use symlinks or hardlinks instead of a wrapper
script. This might have some promise, except that links are more
likely to fail on windows, and the wrappers generally give you
more flexibility for testing odd scenarios.
4. The test-bin-wrapper.sh script does not actually need to
set environment variables (GIT_EXEC_DIT and templates) for
purposes of this patch. But my thought was that in this form
you could run things straight out of the test-bin directory
to manually try out new code without needing to actually install
a build or mess with the environment variables yourself. It could
also be extended to handle other global wrapper needs
relatively easily, such as valgrind.
Any other ideas?
