It may hide the immediate issue, but I am afraid Jonathan's patch does not fix anything fundamental. If you do this:
git checkout next
make
git checkout master ;# without 'make clean'
make && cd t && sh ./t9902-*.shthen the completion machinery will see the leftover git-check-ignore at the top of the working tree (which is the $GIT_EXEC_PATH) and the test that expects "check" to expand only to "checkout" will fail, because 'master' does not have exclusion definition for check-ignore, even though it knows check-attr, check-ref-format and checkout-index are to be excluded as "plumbing".
So if you come up with a brilliant idea to add "git cherry-pack" command and did this:
git checkout -b tb/cherry-pack
edit Makefile builtin/cherry-pack.c builtin.h git.c ...
git add builtin/cherry-pack.c
make test
git commit -a -m "cherry-pack: new command"
git checkout master ;# without 'make clean'
make && cd t && sh ./t9902-*.shthe test will break exactly the same way.
If we really wanted to exclude random build artifacts that the current checkout did not build, you have to do one of these things:
(1) at the beginning of t9902, "rm -fr" a temporary location,
install the built product with a custom DESTDIR set to that
temporary location that we now know is empty, and point
GIT_EXEC_PATH to the libexec/git-core directory in that
temporary location, so that "git help -a" run in the completion
script will find _only_ the executable we would install; or (2) instead of being inclusive, collecting all executable in
GIT_EXEC_PATH that happens to be named "git-", add a mode to
"git help" that lists those that we know to be standard
commands that the users may want to complete from the command
line.An outline to do (2) would look like this patch, but I didn't check other consumers of command-list.txt, so this may be breaking them in unplanned ways.
