My Git Dev Blog - Week 13

Here's the link to the blog: <https://atharvaraykar.me/gitnotes/week13>

Since it's a short one, I'll share the text here as well:

1 Week 13: Preparing for the wrap up
====================================

2 Project Progress
==================

This week's update will be relatively short, partly because I will be out of town and juggling multiple things this week, and also because I am saving up for the larger final report ;-)

This week I re-rolled my [run-update-procedure] patch. I was tempted to also send out my series that [converts the rest of submodule update] to C, but it is quite a big series, and it doesn't help that we are already at the release week for Git. I felt I should be a little more patient, and wait for run-update-procedure to get picked up first rather than send a storm of all these related series at once, at a time of release rush.

In other news, my attempt to making submodule a fully C builtin is shaping up well. Here's a brief of how the transition will work:

- We have a switch called submodule.useBuiltin (as well as GIT_TEST_SUBMODULE_USE_BUILTIN as an environment variable for the test suite) which defaults to false. When set to true, we use the builtins that are purely in C.

- If the switch is set to true, but the user requests a command that has not been converted yet, it falls back to using the old shell starting point. This allows us to test the newly ported builtins with the switch set to true, while still passing the test suite as a whole.

I expect this transition to be rather brief, because the commands are already implemented, all we need to do is manage the flag parsing. As of now [I have already ported the submodule status command] to a pure C builtin. I am open to taking comments on this approach, feel free to leave them on the GitHub web interface, or on the list.

Have a great weekend!
