This patch only contains the test, I presume this goes on top of https://public-inbox.org/git/20180403222053.23132-1-eddy.petrisor@xxxxxxxxxxxxxx/ which you plan to later submit as one patch including both the change as well as the test. > Currently the test fails, so I am obviously missing something. > Help would be appreciated. > > > 2018-04-04 1:20 GMT+03:00 Eddy Petrișor <eddy.petrisor@xxxxxxxxxxxxxx>: >> From: Eddy Petrișor <eddy.petrisor@xxxxxxxxx> >> >> If a submodule uses a non-default branch and the branch info is versioned, on >> submodule update --recursive --init the correct branch should be checked out. >> >> Signed-off-by: Eddy Petrișor <eddy.petrisor@xxxxxxxxx> >> --- >> t/t7406-submodule-update.sh | 54 +++++++++++++++++++++++++++++++++++++++++++++ >> 1 file changed, 54 insertions(+) >> >> diff --git a/t/t7406-submodule-update.sh b/t/t7406-submodule-update.sh >> index 6f083c4d6..7b65f1dd1 100755 >> --- a/t/t7406-submodule-update.sh >> +++ b/t/t7406-submodule-update.sh >> @@ -259,6 +259,60 @@ test_expect_success 'submodule update --remote should fetch upstream changes wit >> ) >> ' >> >> +test_expect_success 'submodule update --remote --recursive --init should fetch module branch from .gitmodules' ' >> + git clone . super5 && I found adding "test_pause &&" to be a great helper as it will drop you in a shell where you can inspect the repository. >> + git clone super5 submodl2b2 && >> + git clone super5 submodl1b1 && We may want to cleanup after the test is done: test_when_finished "rm submodl2b2" && test_when_finished "rm submodl1b2" && >> + cd submodl2b2 && I'd think the test suite prefers subshells to operate in other dirs instead of direct cd's, just like at the end of the test. For short parts, we make heavy use of the -C option, So for example the code below ( cd super && git submodule update --recursive --init ) && can be written as git -C super submodule update --recursive --init which is shorter. >> + echo linel2b2 > l2b2 && style: The Git test suite prefers to have the redirect adjacent to the file name: echo hello >world >> + git checkout -b b2 && >> + git add l2b2 && >> + test_tick && >> + git commit -m "commit on b2 branch in l2" && >> + git rev-parse --verify HEAD >../expectl2 && So until now we made a commit in a submodule on branch b2 and wrote it out to an expect file. >> + git checkout master && >> + cd ../submodl1b1 && >> + git checkout -b b1 && >> + echo linel1b1 > l1b1 && >> + git add l1b1 && >> + test_tick && >> + git commit -m "commit on b1 branch in l1" && very similar to above, just in another repo instead of making a commit yourself, you may want to use test_commit <name> then you don't need to call echo/add/commit yourself. >> + git submodule add ../submodl2b2 submodl2b2 && >> + git config -f .gitmodules submodule."submodl2b2".branch b2 && >> + git add .gitmodules && >> + test_tick && >> + git commit -m "add l2 module with branch b2 in l1 module in branch b1" && So one submodule is made to be a submodule of the other with a specific branch (b2) >> + git submodule init submodl2b2 && git submodule add ought to have initialized that submodule already, I am not sure we need the explicit init here. >> + git rev-parse --verify HEAD >../expectl1 && >> + git checkout master && We go back to master, which doesn't have the nested submodule? >> + cd ../super5 && >> + echo super_with_2_chained_modules > super5 && >> + git add super5 && >> + test_tick && >> + git commit -m "commit on default branch in super5" && >> + git submodule add ../submodl1b1 submodl1b1 && >> + git config -f .gitmodules submodule."submodl1b1".branch b1 && >> + git add .gitmodules && >> + test_tick && >> + git commit -m "add l1 module with branch b1 in super5" && now we do this again without the nested submodule, just one repo as a submodule? >> + git submodule init submodl1b1 && >> + git clone super5 super && does super exist here already?
