why this? It looks like you're removing backspace to navigate backwards 
(which.. is happening, but it should be orthogonal to this)

[tapted, 2016/06/22 03:06:10]

why this change? Cmd+9 to select the last tab works on a Cocoa browser. Ctrl+9
isn't anything.

[themblsha, 2016/06/24 18:22:15]

Because it isn't present in the accelerators_cocoa.mm. Updated to use
kPlatformModifier as well.

[tapted, 2016/06/28 05:19:54]

This isn't a good rationale. How does Cmd+9 work on Cocoa without the mapping?
(is it mapped somewhere else?). Is Cmd+9 actually broken on mac_views_browser?
Does adding this fix it?

I guess this rationale needs to apply to the CL in general, and the bug you've
filed. It's not enough to say "this doesn't match accelerators_cocoa.mm". We
also need to identify that having them not match is causing a problem, and that
mapping them all fixes all the problems.

You need to test all the accelerators you're adding; confirm that they currently
don't work, and that they function correctly after mapping them.

It's possible there's other hidden stuff. Like "this key is intercepted
elsewhere somehow so mapping here doesn't work". We need to verify that the
changes being added are functional and useful, and not just say "make it look
the same as accelerators_cocoa.mm"  (i.e. we don't know whether mimicing
accelerators_cocoa.mm in this way is the correct way to fix the underlying
issues, because we haven't even properly identified what those underlying issues
are).

you can't just add alt here - it will change other platforms. This probably
needs to be #ifdef'd out on Mac so we can add a version with alt in the mac

Chome doesn't allow statics of non-primitive type since it places a destructor
call in the process shutdown path. You can use CR_DEFINE_STATIC_LOCAL instead

I thought there was a compile-time warning for this in the Chromium-Style
plugin? Done.

[tapted, 2016/06/28 05:19:54]

There probably should be :). We detect static initializers on globals with a
script running in the waterfall, which picks them up, but very late. However,
AFAIK, there's nothing for statics local to a function.

The idiomatic way to do this is probably

accelerators.insert(accelerators.begin(), std::begin(kAcceleratorMap),

although I guess assigning an rvalue will just call vector::swap too, but if you
prefer that, it should still be constructed using std::end (and
kAcceleratorMapLength isn't used for anything else so can be deleted)

[tapted, 2016/06/22 03:06:09]

I think we need a "harder" rule here for Mac -- we can't just say it's not
typical since it starts to rely on coincidence with the current set of
accelerators. E.g. we can say

"Alt by itself (or with just shift) is never used on Mac since it's used to
generate non-ASCII characters. Such commands are given Mac-specific bindings as
well, so remove the mappings with Alt, but not those with Command or Control.

then

  const kMask = ui::EF_COMMAND_DOWN | ui::EF_CONTROL_DOWN | ui::EF_ALT_DOWN;
  auto remove_start = remove_if(...[](..) {
    return (m.modifiers & kMask) == ui::EF_ALT_DOWN;
  }

then we should have something like

#if DCHECK_IS_ON()
  // For everything being removed, ensure there's another mapping.
  for (auto it = remove_start; it != accelerators.end(); ++it) {
    auto found = std::find_if(accelerators.start(), remove_start,
        [](const AcceleratorMapping& m) {
          return m.command_id == it->command_id;
        });
    DCHECK(found != accelerators.end());
  }
#endif
  accelerators.erase(..)


I'm undecided about the DCHECK_IS_ON bit - owners might not like it. A test
might be a nicer place for it, but that requires exposing some extra stuff.
Also, there might be some annoying cases that fail, but I think it's worth
trying.
