Hi,

I have gone through commit.c, builtin/commit.c and api-config.txt but one
thing I cannot find is which functions handle writing config file to disk
after adding a new variable,value pair(for example git config my.option
true) . It is also marked TODO on the api-config.txt file. Can somebody help
me , I just want the starting function and will trace the function calls
after that.

Regards,
Tanay Abhra.

Try starting in cmd_config (in builtin/config.c), the main entry point
for running "git config", and you should be able to trace it from there.

The main logic ends up in the git_config_set_* functions.
