Updating patch status
~~~~~~~~~~~~~~~~~~~~~
It may be tempting to help the maintainers and update the state of your
own patches when you post a new version or spot a bug. Please **do not**
do that.
Interfering with the patch status on patchwork will only cause confusion. Leave
it to the maintainer to figure out what is the most recent and current
version that should be applied. If there is any doubt, the maintainer
will reply and ask what should be done.
Contributors and reviewers do not have the permissions to update patch
state directly in patchwork. Patchwork doesn't expose much information
about the history of the state of patches, therefore having multiple
people update the state leads to confusion.
Instead of delegating patchwork permissions netdev uses a simple mail
bot which looks for special commands/lines within the emails sent to
the mailing list. For example to mark a series as Changes Requested
one needs to send the following line anywhere in the email thread::
pw-bot: changes-requested
As a result the bot will set the entire series to Changes Requested.
This may be useful when author discovers a bug in their own series
and wants to prevent it from getting applied.
The use of the bot is entirely optional, if in doubt ignore its existence
completely. Maintainers will classify and update the state of the patches
themselves. No email should ever be sent to the list with the main purpose
of communicating with the bot, the bot commands should be seen as metadata.
The use of the bot is restricted to authors of the patches (the ``From:``
header on patch submission and command must match!), maintainers themselves
and a handful of senior reviewers. Bot records its activity here:
https://patchwork.hopto.org/pw-bot.html
