Re: Git 2.8.1 fails test 32 of t7300-clean.sh, breaks profile build

[Jan Keromnes <janx@linux.com>]

Thanks for your replies! I was able to reproduce to failure on Git 2.8.2.

Steps:

# Build Git 2.8.2 and run t/t7300-clean.sh in a Dockerfile based on
ubuntu:14.04.
RUN mkdir /tmp/git \
 && cd /tmp/git \
 && curl https://www.kernel.org/pub/software/scm/git/git-2.8.2.tar.xz | tar xJ \
 && cd git-2.8.2 \
 && make all && cd t && ./t7300-clean.sh -d -i -v -x

Logs:

expecting success:
        rm -fr to_clean possible_sub1 &&
        mkdir to_clean possible_sub1 &&
        test_when_finished "rm -rf possible_sub*" &&
        echo "gitdir: foo" >possible_sub1/.git &&
        >possible_sub1/hello.world &&
        chmod 0 possible_sub1/.git &&
        >to_clean/should_clean.this &&
        git clean -f -d &&
        test_path_is_file possible_sub1/.git &&
        test_path_is_file possible_sub1/hello.world &&
        test_path_is_missing to_clean

+ rm -fr to_clean possible_sub1
+ mkdir to_clean possible_sub1
+ test_when_finished rm -rf possible_sub*
+ test 0 = 0
+ test_cleanup={ rm -rf possible_sub*
                } && (exit "$eval_ret"); eval_ret=$?; :
+ echo gitdir: foo
+
+ chmod 0 possible_sub1/.git
+
+ git clean -f -d

not ok 32 - should avoid cleaning possible submodules
#
#               rm -fr to_clean possible_sub1 &&
#               mkdir to_clean possible_sub1 &&
#               test_when_finished "rm -rf possible_sub*" &&
#               echo "gitdir: foo" >possible_sub1/.git &&
#               >possible_sub1/hello.world &&
#               chmod 0 possible_sub1/.git &&
#               >to_clean/should_clean.this &&
#               git clean -f -d &&
#               test_path_is_file possible_sub1/.git &&
#               test_path_is_file possible_sub1/hello.world &&
#               test_path_is_missing to_clean
#

Judging from the line "Removing possible_sub1/", it looks like Git
2.8.2 removes a possible submodule while executing `git clean -f -d`,
whereas the test expects it not to.

Is it possible to make Git's output even more verbose, so that it
tells why it decides to remove "possible_sub1"? Are you able to
reproduce this test fail on your side?

This prevents doing a full profile build.

Best,
Jan
