The compiler will crash for really large Objective-J files as the array with code segments will hit this limit.
The solution is to append the array segment by segment.
This new warning adds a lot of warnings in the Cappuccino frameworks. I have turned off
the warning in the Jakefiles when compiling most of the Cappuccino frameworks. But it is
on as default for any user projects.
So there is also a new feature to turn off/on warnings as a compiler flag.
These flags are (all flags are on as default):
-Wunused-but-set-variable Warning when a local variable is never read.
-Wshadow-ivar Warning when a local variable is shadowing an instance variable for the class.
-Wcreate-global-inside-function-or-method Warning when creating a global variable inside a function or method.
-Wunknown-class-or-global Warning when a class or global variable is not known.
-Wunknown-ivar-type Warning when the type for an instance variable is not known.
To turn off a flag add a 'no-' prefix. Example: -Wno-unused-but-set-variable
For an example how to use it in a Jakefile please look at the Jakefiles in this commit.
An example:
var array = @[ @{@"Name": @"1"},
@{@"Name": @"2", @"approveTime": @"Now"}
];
var predicate = [CPPredicate predicateWithFormat:@"approveTime != nil"];
CPLog(@"result: %@", [array filteredArrayUsingPredicate:predicate]); // result: <empty array>
If I run this in Cappuccino I get an empty array
If I run it in Cocoa on a Mac I get:
result: (
{
Name = 2;
approveTime = Now;
}
Calculations of the visible rect can be a heavy operation as it depends of the superviews
visible rect. They have to be transformed and intersected together to create the result.
This calculation is a recursive operation that travels up the view hierarchy all the way
to the top.
Updating the tracking areas is also a recursive operation. But it travels down the view hierarchy
instead. It will calculate the new tracking area using the visible rect for the current view. For
each view it updates it will get the visible rect that has to travel all the way up the view
hierarchy to calculate it by transform and intersect them together. This results in that the visible
rect will be calculated for each view multible times. This makes it a very slow operation, specially
for deeper view hierarchies.
This fix will send along the visible rect for the superview when traveling down the
view hierarchy. This means that the visible rect does not need to travel up the view hierarchy
to be calculated. It will just need transform and intersect the provided rect for its superview
with the one from itself.
This makes updating views much faster when they need layout. This will make resizing browser window and changing split views sizes much smoother.
The effectiveAppearance is inherited from the superview. The superviews appearance is passed along as it is recomputed down the view hierarchy.
Also the current appearance is saved on each view to make it possible to only change the theme states when the appearance is changed.
This speed improvement is very notable when resizing a browser window of altering the size of split views.
The fix uses a variable on the window to control when to update the tracking areas.
If the view is not connected to a window the tracking areas will not be updated as they will
be when added to a window.
This pull request adds a kvoValueForKey: method used by _CPKVOForwardingObserver for getting values.
The default action is to just return the valueForKey value.
Override this method if you want any other behavior.
It can be used to just return nil if you are implementing a lazy load behavior on a class.
It can allow a combined binding to observe this object without trigger any lazy loading.
The default was to make the first window in the most background layer the key window if nothing else was used.
This does not work well if there is a modal window that should have all the attention.
This solution will first choose the modal window if in modal mode. If not the old variant is used.
