[PATCH 0/2] bug fix with push --dry-run and submodules

[PATCH 0/2] bug fix with push --dry-run and submodules

[Brandon Williams]

While trying to understand how the recursive pushing of submodules worked I
discovered that when push was instructed to do a dry-run, while also configured
to push unpushed submodules 'on-demand', that the submodule pushes weren't
configured to perform dry-runs, but actually performed the pushes.  This
resulted in the submodules being pushed while leaving the superproject unpushed
which is undesirable behavior for a dry-run.

This series introduces a test to illustrate the bug as well as a patch to
correct this behavior by passing the --dry-run flag to the child processes
which perform the submodule pushes during a dry-run.

This series is based against 'origin/hv/submodule-not-yet-pushed-fix'

[PATCH 1/2] push: --dry-run updates submodules when --recurse-submodules=on-demand

[Brandon Williams]

This patch adds a test to illustrate how push run with --dry-run doesn't
actually perform a dry-run when push is configured to push submodules
on-demand.  Instead all submodules which need to be pushed are actually
pushed to their remotes while any updates for the superproject are
performed as a dry-run.  This is a bug and not the intended behaviour of
a dry-run.

[PATCH 2/2] push: fix --dry-run to not push submodules

[Brandon Williams]

Teach push to respect the --dry-run option when configured to
recursively push submodules 'on-demand'.  This is done by passing the
--dry-run flag to the child process which performs a push for a
submodules when performing a dry-run.

In order to preserve good user experience, the additional check for
unpushed submodules is skipped during a dry-run when
--recurse-submodules=on-demand.  The check is skipped because the submodule
pushes were performed as dry-runs and this check would always fail as the
submodules would still need to be pushed.

This line looks like a clean-up to be done after the test case. You 
should wrap it in test_when_finished, but outside of a sub-shell, which 
looks like it's just one line earlier, before the test_cmp.

Could you please avoid this nested sub-shell? It is fine to cd around 
when you are in a sub-shell.

Broken && chain.

All of the commands above are 'git something' that could become 'git -C 
work something' and then the sub-shell would be unnecessary. I'm not 
sure I would appreciate the verbosity of the result, though. (Perhaps 
aligning the git subcommands after -C foo would help.)

Yes I can reorganize it to avoid the nested sub-shells.  I was just
trying to follow the organization of the other tests in the same file.

I'll play around with it and try to make it look pretty while trying to
avoid sub-shells.  I'm assuming the reason we want to avoid sub-shells is
for performance reasons right?

This patch adds a test to illustrate how push run with --dry-run doesn't

pushed to their remotes while any updates for the superproject are
performed as a dry-run.  This is a bug and not the intended behaviour of
a dry-run.

an interdiff to v1 would be nice :)

Now t5531 is inconsistent in style,
how much time would you estimate to add a commit to refactor
that test to follow the style with excessive use of -C for
all the other tests and avoiding subshells there, too?
(It's mainly Windows that benefits from such a refactoring immediately,
but consistency is a really nice feat for the long term code health
of the Git project)

Apart from one nit (and this refactoring decision/consistency discussion),
the series looks good!

Thanks,
Stefan

That's odd...I didn't mean to add that lone space.

I didn't change to an excessive use of the -C option, but rather
eliminated the nested-subshell and instead cd'ed to the required
directories in the subshell.  Excessive use of -C seemed to greatly
reduce the readability of the test (at least it did to me).

Is that the only glitch in this round?  IOW, is the series OK to be
picked up as long as I treak this out while queuing?

It looks that way.  And I did fix this in my local series.  Let me know
if you would rather I resend the series. Otherwise I think it looks
good.

I do also have a follow on series I'm planning on sending out later to
actually add in a feature which mimics what this bug does (as this
functionality could be desirable in some circumstances) but thought it
best to wait till heiko's and this series were more stable.

OK, queued with trivial fix for now.

Thanks.
