Hey everyone, Bug 1201190 (https://bugzilla.mozilla.org/show_bug.cgi?id=1201190) just landed on inbound, which means that we now have access to the new annotation MOZ_RAII. This is a static-analysis annotation, intended to be placed on RAII guards. It will cause the static analysis to cause compilation to fail if the class is allocated anywhere other than in an automatic variable - this includes temporaries, unlike MOZ_STACK_CLASS, which also allows allocating the type in a temporary.
This new analysis fills the role of the much more verbose MOZ_GUARD_OBJECT annotations, which perform runtime analysis to prevent temporary allocations. Unfortunately, as we currently only run static analysis on Linux and Mac OS X, you should still use MOZ_GUARD_OBJECT (In addition to MOZ_RAII - which is more likely to catch errors, as it checks at build time and is more thorough) if the class might be used from windows-specific code. To mark a class as MOZ_RAII, simply `#include "mfbt/Attributes.h"`, and then change the class declaration to `class MOZ_RAII FooGuard`. If you're adding any new RAII guards, please use MOZ_RAII! Thanks :D _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
