Not only do debuggers catch the expected SIGSEGV by default, I'm not
sure there's a working way to configure either gdb or lldb not to. This
commit uses an OS X-specific mechanism to add an exception handler that
runs before the default one.
It isn't easily accessible with sigaction or Mach exceptions (well,
requires an additional system call in the latter), and isn't necessary.
(and get rid of the enum, because it's only used once, and the comments
are more expressive than enum names)
It tried to cast incoming pointers to native ones. The values are
required to be null anyway, so it doesn't really matter, but it fixes a
warning at least.
MSVC insisted on using a copy assignment where a move was intended and
ought to be used. This would have been caught, because the class in
question inherits from NonCopyable, which declares a move assignment
operator, which is supposed to delete the implicitly declared copy
assignment operator, but of course MSVC didn't do that either, causing a
class that should have been safe to be unsafe.
(Intertwined enough that's it's easier to do in one patch.)
(1) /dev/es did not support state save, which could cause crashes and
incorrect behavior after loading.
(2) NANDContentLoader tried to read all of a title's contents into
memory when it was first opened. Two issues:
- If any contents were missing, it bailed out. However, with DLC,
only some of the contents may be downloaded, as determined by the
permission bits in the ticket. Instead, return an appropriate error
when a content is accessed that doesn't exist on the filesystem
(don't bother checking the permission bits though).
- Everything was loaded into memory - even if it consisted of 3 GB of
songs, which caused Dolphin to lag out for quite a while (and would
fail on 32-bit). Instead, open content on demand.
The code was hitting undefined behavior, causing crashes when starting a Wii
game with Dolphin compiled with gcc >= 4.8.
Might introduce some slight change in the Wiimote activation logic.
Fixes issue 6526.
