54709dbdd6 Bug 1523631 - Part 5: Avoid GCC warning when including dictionary types in WebIDL, r=bzbarsky
This warning (as an error) is showing up with this patch due to the new
use of AddEventListenerOptions in ChromeUtilsBinding.h. That header is
included in some codegen units which have this warning enabled, which
revealed the issue.

I believe the warning is spurious in this case, but fixing it doesn't
seem like a big deal. Requesting review from Boris, as he added the
comment 6 years ago.

ef3ad686ee Bug 1512504 - Remove support for MSVC. r=froydnj
Consequently, this removes:
- MOZ_LIBPRIO, which is now always enabled.
- non_msvc_compiler, which is now always true.
- The cl.py wrapper, since it's not used anymore.
- CL_INCLUDES_PREFIX, which was only used for the cl.py wrapper.
- NONASCII, which was only there to ensure CL_INCLUDES_PREFIX still
  worked in non-ASCII cases.

This however keeps a large part of detecting and configuring for MSVC,
because we still do need it for at least headers, libraries, and midl.

e962578670 Bug 1518661 - Part 3: Adjust call-expression positions. r=jimb,jorendorff
When we mark call expressions as breakpoints, we want to make it as likely
as possible that the call has its own unique positon. The existing logic
means that it is more likely that the beginning of a call will align
with the start of an expression statement or other debuggable step point.
By using the property-access location, we're less likely to collide.

Thid also adds a new bytecodes that were missed in the original code that
added this position handling logic.

bc348929b6 Bug 1515582. Remove the separate XBL scope setup. r=bholley
With these changes, XBL just runs in the window scope of whatever document it's
attached to.  Since (outside of tests and "remote XUL") we no longer attach XBL
to web documents, this is fine.  And "remote XUL" already ran without the XBL
scope.

Native anonymous content, which used to be placed in the XBL scope to hide it
from the page, is now placed in the unprivileged junk scope, so it stays hidden
from the page.

dom/xbl/test/test_bug944407.xul is being removed because we are changing the
behavior it's trying to test for.  Since we now always put the XBL in the same
scope as the page, script is enabled for the XBL if and only if it's enabled for
the page.

dom/base/test/test_bug419527.xhtml, dom/events/test/test_bug391568.xhtml,
dom/xbl/test/test_bug1086996.xhtml are being switched to a chrome test because
otherwise the XBL can't see the getAnonymousNodes method.

All the XBL bits are being removed from test_interfaces because we no longer
have a separate XBL scope to test the behavior of.

js/xpconnect/tests/mochitest/test_nac.xhtml is being removed because XBL no
longer has access to NAC unless the page it's attached to does too, so the test
doesn't really make sense.

layout/xul/test/test_bug1197913.xul is being switched to a chrome test because
its XUL elements use bindings that rely on APIs that are not exposed to normal
web content.

layout/reftests/bugs/495385-2f.xhtml is being removed because I can't think of
a sane way to test that in the new world, short of running the reftest as
chrome.  And it doesn't seem worthwhile to look for a way to do that.

dom/xbl/test/test_bug1098628_throw_from_construct.xhtml now needs to
expectUncaughtException(), because the exception is now being thrown in Window
scope.

dom/xbl/test/test_bug1359859.xhtml needs to expectUncaughtException() as needed
and not use XPCNativeWrapper (which it doesn't need to anyway now).

dom/xbl/test/test_bug389322.xhtml, dom/xbl/test/test_bug400705.xhtml,
dom/xbl/test/test_bug401907.xhtml, dom/xbl/test/test_bug403162.xhtml,
dom/xbl/test/test_bug526178.xhtml, dom/xbl/test/test_bug639338.xhtml don't need
to use XPCNativeWrapper anymore.

dom/xbl/test/test_bug821850.html is being removed because it exists only to test XBL scopes.

dom/xbl/test/file_bug950909.xml is being changed to work without a separate XBL
scope (though whether the test still makes sense at that point is a bit questionable).

7e5a37a024 Bug 1521907 part 3. Start using CheckedUnwrapStatic/Dynamic in bindings. r=peterv
The basic idea for the changes around UnwrapObjectInternal and its callers
(UnwrapObject, UNWRAP_OBJECT, etc) is to add a parameter to the guts of the
object-unwrapping code in bindings which can be either a JSContext* or nullptr
(statically typed).  Then we test which type it is and do either a
CheckedUnwrapDynamic or CheckedUnwrapStatic.  Since the type is known at
compile time, there is no actual runtime check; the compiler just emits a call
to the right thing directly (verified by examining the assembly output on
Linux).

The rest of the changes are mostly propagating through that template parameter,
adding static asserts to make sure people don't accidentally pass nullptr while
trying to unwrap to a type that might be a WindowProxy or Location, etc.

There are also some changes to places that were calling CheckedUnwrap directly
to use either the static or dynamic version, as needed.

e930b89c34 Bug 1514594: Part 3 - Change ChromeUtils.import API.
***
Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8

This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:

  ChromeUtils.import("resource://gre/modules/Services.jsm");

is approximately the same as the following, in the new model:

  var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");

Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

c17e30f6b2 Bug 1363208 part 4. Stop using cross-origin Xrays for WindowProxy. r=peterv,jandem
The change to test_bug440572.html is due to a behavior change.  Specifically,
before this change, any IDL-declared property, even one not exposed
cross-origin, would prevent named frames with that name being visible
cross-origin.  The new behavior is that cross-origin-exposed IDL properties
prevent corresponding frame names from being visible, but ones not exposed
cross-origin don't.  This matches the spec and other browsers.

Same thing for the changes to test_bug860494.xul.

The wpt test changes are just adding test coverage for the thing the other
tests caught.

3c5a7b2986 Bug 1517415. We might be trying to JS-wrap a BrowsingContext with a torn-down-enough docshell that we have no window. r=nika
The old code did this check in GetContentWindow, basically.  We _could_ just put
the null-check there, but this seems safer.

58c7fc4d20 Bug 1353867 - Change WindowProxyHolder's native type to BrowsingContext. r=bzbarsky
Make the WindowProxyHolder hold a strong reference to a BrowsingContext, as in the future
we might not have a nsPIDOMWindowOuter (if the document is loaded in a different process).
