We may want to convert the _INIT macro to use the designated initializers; I had to count the fields twice to make sure I was tweaking the right one. It did not help that I saw, before looking at the current code, that 90efe595c5 added one field at the end to the struct but did not touch _INIT macro at all. That made me guess that max_jobs=0 was due to _missing_ initialization value, leading me to an incorrect fix to append an extra 1 at the end, but that was bogus. The missing initialization left by 90efe595 ("builtin/submodule--helper: factor out submodule updating", 2018-08-03) was silently fixed by f1d15713 ("builtin/submodule--helper: store update_clone information in a struct", 2018-08-03), I think, so replacing the 0 at the end is 1 happens to be the right fix, but with designated initializers, all these confusions are more easily avoided. > builtin/submodule--helper.c | 2 +- > t/t5526-fetch-submodules.sh | 2 ++ > 2 files changed, 3 insertions(+), 1 deletion(-) > > diff --git a/builtin/submodule--helper.c b/builtin/submodule--helper.c > index d38113a31a..1f8a4a9d52 100644 > --- a/builtin/submodule--helper.c > +++ b/builtin/submodule--helper.c > @@ -1551,7 +1551,7 @@ struct submodule_update_clone { > #define SUBMODULE_UPDATE_CLONE_INIT {0, MODULE_LIST_INIT, 0, \ > SUBMODULE_UPDATE_STRATEGY_INIT, 0, 0, -1, STRING_LIST_INIT_DUP, 0, \ > NULL, NULL, NULL, \ > - NULL, 0, 0, 0, NULL, 0, 0, 0} > + NULL, 0, 0, 0, NULL, 0, 0, 1} > > > static void next_submodule_warn_missing(struct submodule_update_clone *suc, > diff --git a/t/t5526-fetch-submodules.sh b/t/t5526-fetch-submodules.sh > index 6c2f9b2ba2..a0317556c6 100755 > --- a/t/t5526-fetch-submodules.sh > +++ b/t/t5526-fetch-submodules.sh > @@ -524,6 +524,8 @@ test_expect_success 'fetching submodules respects parallel settings' ' > git config fetch.recurseSubmodules true && > ( > cd downstream && > + GIT_TRACE=$(pwd)/trace.out git fetch && > + grep "1 tasks" trace.out && > GIT_TRACE=$(pwd)/trace.out git fetch --jobs 7 && > grep "7 tasks" trace.out && > git config submodule.fetchJobs 8 &&
