Greetings,
If your commit modifies an IDL interface (think `[...] interface Foo
{};`), you will now have to either
1) Bump the corresponding interface UUID.
Use e.g. `./mach update-uuids nsISomething` to bump the UUID of
nsISomething and all its descendant interfaces.
or
2) Include 'IGNORE IDL' in the commit message.
Use this only if your changes don't affect IDL binary or source
compatibility[0].
Your push will otherwise be rejected. Note that changes to comments
and changes outside interface blocks are ignored and don't require any
action.
Also keep in mind that whenever you change an interface UUID, you also
need to change the UUIDs of all descendant interfaces. This is not
enforced by the hook so be sure to always use `./mach update-uuids`
instead of manually changing UUIDs.
The hook has been deployed on the following repos:
mozilla-central
integration/b2g-inbound
integration/fx-team
integration/mozilla-inbound
releases/mozilla-aurora
releases/mozilla-beta
releases/mozilla-release
releases/mozilla-esr31
See bug 1128518 for details.
Cheers,
Biru
