The last bugsweep was performed by thomie in the fall of 2014.
In the tradition of the Ubuntu 5-a-day,
the GHC Bug Sweep is a scheme in a similar vein. The
main aim is simple: we want to make sure that no ticket is
forgotten. So, what we plan to do is to look at every ticket in the
database in sequence, starting from the oldest, and try to make some
progress on the ticket. In this way we'll ensure that we keep the
amount of cruft in the ticket database down to a minimum, keep the database healthy, and keep everything moving.
The bug sweep is a way that virtually anyone can contribute to GHC, in
as small or large a way as you like. Whenever you have a spare minute
or two, claim a ticket and look at it (see below for how to claim a
ticket). You don't necessarily have to fix the bug or implement the
feature: all you have to do is make some progress on the ticket.
Here are some things to check:
Check for duplicates (Google search with "site:gitlab.haskell.org" may be
better than GitLab's search)
Tidy up the description: add markup if necessary, link to related information and/or other tickets
Check that the ticket is categorised correctly, including
the title is a good summary of the bug
platform/OS are correct
component is correct
it is on the correct milestone (developers only)
the "difficulty" is a reasonable estimate (developers only)
If the ticket has a patch
(developers only) review the patch
if it looks ready to go, add a comment to the ticket to say so.
Check that the bug hasn't already been fixed.
Set the new "Type of Failure" field
If the bug has some reproduction instructions, try them out with a recent GHC and see if the bug still happens. If the results are different, update the ticket to include that information.
Note: you don't have to do all of the things on the list. Doing any of them is good. The main thing is that every ticket gets at least looked at.
For many tickets there may be nothing to do: if so, just proceed to the next ticket. You might not be
able to reproduce the bug (because you don't have access to the right
platform, for instance). In that case just add a comment to the
ticket to note that the bug needs to be reproduced with an up to date
GHC, and hopefully someone else will pick it up.
