Dear,
I am Maifee Ul Asad. I have been studying Git's codebase for a while
now. And there is something I noticed about clone functionality.
Whenever I run a clone operation it creates five independent
processes. Now the only way to cancel this cloning operation is
through CLI, press CTRL+C or a relevant command based on different OS.
I have only checked in Windows.
But, when I am creating a wrapper, or I have some existing wrapper for
Git, and I want to add functionality to cancel the cloning process, it
can not be done so easily. Then I have to create a process and pass a
signal interrupt via stdin of that process and cancel it.
I think it would be way cool and lot cleaner if we could create a
parent process and add these processes as children to that parent
process. In this case, we can simply use kill to terminate that parent
process.
Till now I was only able to identify these operations, and I am pretty
helpful they I have identified the correct functions:
- perform the fetch operation
- perform the receive-pack operation
- perform the indexing operation
- perform the pack-objects operation
- perform the update-ref operation
Now we can simply wrap these with a fork (yes, we have to think about
NT not having a fork; and cygwin and other libraries may add tons of
load here) call. But here is my proposed pseudo code:
```
fork a new process
if (fork failed):
log and exit
else if (fork is successful):
perform the fetch operation
perform the receive-pack operation
perform the indexing operation
perform the pack-objects operation
perform the update-ref operation
else:
wait for the child processes to finish
```
I think it would be a great improvement. And, I am really excited
about the discussion we are going to have on this.
Regards
Maifee Ul Asad
