Fix a crash during patching when MySQL support isn't available.
Review Request #12070 — Created Feb. 21, 2022 and submitted
Django Evolution 2.1.3 introduced a patch for modern versions of
mysqlclient
on Django < 2.0. The patch tried to handle the situation
wheremysqlclient
wasn't installed, but it didn't catch the right
exception.This change adds a more broad exception handler, and also exception
handlers in the patch loader, one wrappingneeds_patch()
and one
wrappingapply_patch()
. This will help us avoid other unforeseen
issues in the future.
Ran all unit tests without
mysqlclient
installed.
