commit 2a6c5c9ee3dcb5ca1336a56e2739c24f9d25faa3
Author: Yuki Shiino <yukishiino@chromium.org>
Date: Fri Oct 27 16:22:27 2017

v8binding: Generalize NativeValueTraits<V8CallbackFunction>.

Since all generated callback functions now inherit from
CallbackFunctionBase, we can generalize the specialization of
NativeValueTraits<T> where T is a subclass of CallbackFunctionBase,
and we're no longer in need of generated NativeValueTraits for
callback functions.

commit fb2f0e511b626db083b8ff576fa720d809a0828a

Date: Fri Nov 10 15:21:37 2017

v8binding: Fixes optional vs nullable at callback interface/function.

For callback interface and callback function, this patch fixes
misunderstanding/misuse of info[index] (which supports out-of-range
indexing) and difference between 'optional' and 'nullable'.

You do not need to pass in any argument if it's 'optional', however,
it's mandatory to pass in an argument if it's just 'nullable'.
The number of arguments must be checked in case of 'nullable'.

v8binding: Renovates "invoke" steps of callback function.

This patch implements "invoke" steps of Web IDL from scratch
discarding most part of the existing implementation.  The steps
include (roughly speaking) a step of push a backup incumbent
realm.

Add support of Maybe<void> as a template specialization.

Blink wants to use Maybe<T> as a return type of (author) callback
functions, where T can be type void.  So, this patch adds support
of Maybe<void>.

v8binding: Makes callback functions return v8::Maybe.

Makes callback functions return v8::Maybe so that the
call sites handle an exception if any.

Also this patch renames |call| function to |Invoke|.

For convenience, if the return type of IDL callback
function is void, the bindings code generator defines
|InvokeAndReportException| that captures and swallows
an exception if any.

If the return type of IDL callback function is not
void, the call sites must check the return value.
|InvokeAndReportException| is not defined in non-void
case.

v8binding: Stops using the copyable ver of v8::Persistent.

I learnt that v8::Persistent provides two variations of copying.
One actually copies, and the other actually shares the underlying
slot.

This patch changes CallbackFunctionBase::Persistent from the
"share" version to the "copy" (= make another independent slot)
version.

commit 37f11fd71e75bc3110215c11e03a00556be4845a
Author: Yuki Shiino <yukishiino@chromium.org>
Date: Thu Feb 22 11:47:18 2018

v8binding: Implements v8::Persistent version of CallbackFunctionBase.

CallbackFunctionBase and its subclasses retain the underlying
v8::Function by using wrapper-tracing. However, wrapper-tracing is
not always the best way to make the v8::Function alive.

This patch implements V8PersistentCallbackFunction<T> that retains
the v8::Function with using v8::Persistent so that it doesn't
require wrapper-tracing.  As a natural consequence,
V8PersistentCallbackFunction<T> works very well with WrapPersistent
unlike CallbackFunctionBase doesn't.

Note that CallbackFunctionBase::Persistent was a persistent handle
in terms of both of Blink GC and V8 GC, which is totally different
from that V8PersistentCallbackFunction<T> is only a v8::Persistent
and not a blink::Persistent.  This difference should reduce the
chance of memory leak caused by Oilpan reference cycles.

I also have a plan to remove WrapPersistentCallbackFunction entirely
and WrapPersistent for CallbackFunctionBase and its subclasses in
order to prevent misuse of WrapPersistent.

v8binding: Re-implements V8PersistentCallbackFunction.

Following https://crrev.com/c/928783 , refactors
V8PersistentCallbackFunction<T>.

Major improvements:

- V8PersistentCallbackFunction<T> is no longer a subclass of
  T.  There will be no unintentional conversion between
  wrapper-tracing version and v8::Persistent version.

- WrapPersistent(T*) = delete;
  where T is wrapper-tracing versions of callback functions.
  There will be no misuse of WrapPersistent for wrapper-
  tracing versions.
