Subject: [PATCH v8 11/15] bugreport: collect list of populated hooks
Date: Wed, 19 Feb 2020 17:58:54 -0800
Message-ID: <20200220015858.181086-12-emilyshaffer@google.com> (raw)
In-Reply-To: <20200220015858.181086-1-emilyshaffer@google.com>

Occasionally a failure a user is seeing may be related to a specific
hook which is being run, perhaps without the user realizing. While the
contents of hooks can be sensitive - containing user data or process
information specific to the user's organization - simply knowing that a
hook is being run at a certain stage can help us to understand whether
something is going wrong.

Without a definitive list of hook names within the code, we compile our
own list from the documentation. This is likely prone to bitrot. To
reduce the amount of code humans need to read, we turn the list into a
string_list and iterate over it (as we are calling the same find_hook
operation on each string). However, since bugreport should primarily be
called by the user, the performance loss from massaging the string
seems acceptable.
