difference between start-commit and pre-commit hooks

[Glenn R Heard Jr <gh...@zoominternet.net>]

Is there a big difference in checking the user credentials in the
start-commit versus the pre-commit hooks? I noticed in the hook templates
that a form of auth check is done in both hooks. Currently I do mine in the
pre-commit hook.

The only difference is when the user is booted out.

If the user is rejected by the start-commit hook, then nothing  
happens in the repository at all.

If the user is booted by the pre-commit hook, then the user has  
already built a transaction tree in the repository, and it's only one  
step away from becoming a revision.  If pre-commit fails, then the  
whole repository transaction is aborted.
