Because nsAString is nicer to work with than char16_t*. The patch relatedly
changes nsIEmbeddingSiteWindow::title and nsIWindowMediator::updateWindowTitle
as well.
This is similar like the previous patch, but for the 8-bit string variants.
Also, it changes assignment to Adopt() in GetCString() and GetDefaultCString()
to avoid an extra copy.
This patch replaces four functions of the name AssignWithConversion which
are essentially wrappers around CopyASCIItoUTF16 and LossyCopyUTF16toASCII
with direct calls to the latter two functions. The replaced functions are:
void nsCString::AssignWithConversion( const nsAString& aData )
void nsString::AssignWithConversion( const nsACString& aData )
void nsTString_CharT::AssignWithConversion(
const incompatible_char_type* aData,
int32_t aLength = -1);
The last of the three exists inside the double-included nsTString* world and
so describes two functions, giving four in total.
This has two advantages:
* it removes code
* at the call points, it makes clear (from the replacement name) which
conversion is being carried out. The generic name "AssignWithConversion"
doesn't make that obvious -- one had to infer it from the types.
The patch also removes two commented out lines from
editor/composer/nsComposerCommands.cpp, that appear to be related. They are
at top level, where they would never have compiled. They look like
leftovers from some previous change.
This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.
This function is arguably nicer than calling NS_ProcessNextEvent
manually, is slightly more efficient, and will enable better auditing
for NS_ProcessNextEvent when we do Quantum DOM scheduling changes.
This patch making the nsXULWindow::ForceRoundedDimensions() will only be called
when this window is a window which has a primary content when fingerprinting
resistance is enabled.
This will fix the problem that dialog windows are incorrectly resized after
fingerprinting resistance is enabled.

Other browsers do not support any of these (IIRC), telemetry reports
essentially zero usage, and supporting them is contrary to the DOM spec.
Notes on specific events:
CommandEvent and SimpleGestureEvent: These are not supposed to be
web-exposed APIs, so I hid the interfaces from web content too
(necessary to avoid test_all_synthetic_events.html failures).
DataContainerEvent: This was a non-standard substitute for CustomEvent
that seemed to have only one user, so I removed it entirely and switched
the user (MozillaFileLogger.js) to CustomEvent.
ScrollAreaEvent: This is entirely non-standard, but we apparently expose
it deliberately to web content, so I didn't see any reason to remove it
from createEvent.
SimpleGestureEvent and XULCommandEvent: Can still be created from
createEvent(), but not by content.
TimeEvent: This is still in because it has no constructor, so there's no
other way to create it. Ideally we'd update the SMIL spec to add a
constructor. I did remove TimeEvents.

This patch replaces the usage of sNextTabParent pointer to store the next
PBrowser parent actor to be used by the next frame loader with the
following information:
* In the case where the content JS has requested a new tab, the ID of the
next TabParent will be stored on the <xul:browser> element.
* In the case where the content JS has requested a new window, the ID of
the next TabParent will be stored on the created nsXULWindow.
clang's -Wcomma warning warns about suspicious use of the comma operator such as calling a function for side effects within an expression. Check NS_SUCCEEDED() to use HasMoreElement() in an expression and confirm that it actually returned a legitimate out parameter.

This patch makes the size of inner windows will be automatically rounded for
either window.open() with window features or setting window size through
innerWidth/Height and outerWidth/Height when fingerprinting resistance is
enabled. If the given value is greater the maximum available rounded size, then
it will be set to the maximum value. Otherwise, the size will be set to the
nearest upper 200x100.
This patch also adds one helper function in nsContentUtils for calculating the
rounded window dimensions.

The machinery for suppressing the displayport during live resizes
was using the Observer service. However, in the case of multiple
browser windows, this meant that all the open browser windows would
have their displayport suppressed if *any* of the browser windows
was being resized. This was mostly ok, as the displayport suppression
would be turned off once the resize ended. However, the code to
kick off a repaint with the unsuppressed displayport would only get
triggered on one of the windows (whichever happened to process the
unsuppress message last).
This patch stops using the Observer service for the implementation
machinery, and instead locates the active TabParent of the relevant
nsWindow, and invokes the displayport suppression directly on that.
This fixes the repainting bug and also avoids unnecessarily
broadcasting the suppression/unsuppression notification to windows
that don't neccessarily need it.

This patch makes GetBounds(), GetScreenBounds() and GetClientBounds() more
obviously infallible, like existing functions such as GetNaturalBounds() and
GetClientSize(). This results in clearer behaviour in nsCocoaWindow.mm if
Objective C exceptions occur. Along the way, the patch removes some useless
failure checks for these functions.
The patch also removes the NS_IMETHOD from GetRestoredBounds and makes that
function MOZ_MUST_USE.
This will make sure that window.scrollbars correctly reflects the respective
chrome flags in e10s mode.
We also update nsXULWindow::SetContentScrollbarVisibility() to the new
nsContentUtils helper. That code is responsible for doing this work in the
single process case.
