Description

Race condition between the main thread and a thread used by CADisplayLinkTicker
CADisplayLinkTicker invokes Quartz.CATransaction.commi()t which is deciding to do an auto layout while not on the main thread, in the main thread we are adding/removing ContentViews (Note class in our code) to an AbsoluteLayout

Have you solved this problem? I have very similar one. StackTrace points to the SkiaSharp surface.canvas.DrawPath(path, Paint); in method bound to the event PaintSurface. The crash occurs randomly but about 30-90seconds after the startup.

EDIT: downgrade to 1.59.0 solved it

Reproduction project, this is an iOS-only issue, also it only happens on physical devices we used an iPhone 8 (MQ6G2VC/A) version 11.2.6

For us it takes 1 to 5 minutes for the app to crash.

Thanks.

Annoying thanks, this is almost certainly due to the off thread update to CALayer (which is allowed normally). We'll probably need to provide a mechanism to disable that wholesale for users like yourself.

* [msbuild] use portable pdb files (xamarin#4201)

Currently, on the first build of a "Hello World" Xamarin.Forms app,
you will see this in the build log:

    ConvertDebuggingFiles
        Parameters
            Files
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\FormsViewGroup.pdb
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\Xamarin.Forms.Platform.Android.pdb
        OutputItems
            _ConvertedDebuggingFiles
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\FormsViewGroup.dll
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\Xamarin.Forms.Platform.Android.dll

The logging is a little weird here, but this `ConvertDebuggingFiles`
MSBuild task takes about 100ms on my machine.

What is it doing?

The Mono debugger can support two types of debugging files:
- `mdb` files
- "portable" `pdb` files

If Xamarin.Android's build finds a "non-portable" `pdb` file, we have
to run it through this task to convert to an `mdb` file... This gives
us proper stacktraces for `FormsViewGroup.dll` and
`Xamarin.Forms.Platform.Android.dll`.

You can change the type of debugging symbols in your project with the
`DebugType` setting, which has these options:
- Blank or `None`: don't generate symbols. (Although Xamarin.Android
  has funny behavior here, see:
  xamarin/xamarin-android#2282)
- `Full` generates an `mdb` file, this is a Windows-proprietary format
  for debug builds
- `PdbOnly` generates a "non-portable" `pdb` file, a
  Windows-proprietary format for release builds
- `Portable` generates a "portable" pdb file, which is the new
  standard that works for debug and release builds. New SDK-style
  MSBuild projects use this option by default.

These values are not case sensitive, I have mostly seen them lower
case in newer projects.

So what does Xamarin.Forms need to do?

Use `<DebugType>portable</DebugType>` in any Android class library or
app project. Other platforms, this is optional, not as much benefit. I
have heard that `DebugType=portable` might cause a problem on UWP.

* Xamarin.Forms will ship "portable" `pdbs` in its NuGet package for
  `FormsViewGroup.dll` and `Xamarin.Forms.*.Android.dll`. Developers
  won't pay the 100ms on initial build.
* Initial build times for `Xamarin.Forms.sln` will be slightly better
  for development, although I didn't measure the difference here.

regression.
This changes Trim() the input, to be fully backward compatible.

* [GTK] Fix several memory leaks in the GTK backend (xamarin#4112)

* [GTK] Don't recreate master or detail if it didn't change

* [GTK] Fix several memory leaks using the Destroy pattern

Gtk objects must be disposed using the Destroy function that will
automatically iterate over the children and destroy them too:
https://developer.gnome.org/gtk2/stable/GtkWidget.html#gtk-widget-destroy

The gtk-sharp bindings discourage the use of Dispose and don't even call
the base class, leaving it without effect:
https://github.com/mono/gtk-sharp/blob/gtk-sharp-2-12-branch/gtk/Object.custom#L98

In the Controls, that inherits directly from native Gtk objects, the
overrides of the Dispose function are changed to override the Destroy
function.  In the Renderers, that inherit from VisualElementRenderer,
the Destroy funtion is called in the dispose implementation so
subclasses only have to override Dispose (bool disposing) as they do
now.

updates and handled with more fairness.

* Update from origin (#8)

* [C] VisibilityConverter Trims input (#3581)

For CSS purposes, the VisibilityConverter was added, and actually
replaced the `Boolean.Parse(str)` call for parsing Visibility.
`Boolean.Parse()` trims input, and the converter was not, so this was a
regression.
This changes Trim() the input, to be fully backward compatible.

* [A] do not draw gradient for empty CornerRadius (#3786)

Drawing CornerRadius (introduce by #1998) when the CornerRadii are
actually 0 causes scaling artifacts on API < 25.

This fixes the regression when no CornerRadius is set. Expect blurry
border scaling with CornerRadius not empty and API < 25

* Update from origin (#9)

* [C] VisibilityConverter Trims input (#3581)

For CSS purposes, the VisibilityConverter was added, and actually
replaced the `Boolean.Parse(str)` call for parsing Visibility.
`Boolean.Parse()` trims input, and the converter was not, so this was a
regression.
This changes Trim() the input, to be fully backward compatible.

The logging is a little weird here, but this `ConvertDebuggingFiles`
MSBuild task takes about 100ms on my machine.

What is it doing?

The Mono debugger can support two types of debugging files:
- `mdb` files
- "portable" `pdb` files

If Xamarin.Android's build finds a "non-portable" `pdb` file, we have
to run it through this task to convert to an `mdb` file... This gives
us proper stacktraces for `FormsViewGroup.dll` and
`Xamarin.Forms.Platform.Android.dll`.

You can change the type of debugging symbols in your project with the
`DebugType` setting, which has these options:
- Blank or `None`: don't generate symbols. (Although Xamarin.Android
  has funny behavior here, see:
  https://github.com/xamarin/xamarin-android/issues/2282)
- `Full` generates an `mdb` file, this is a Windows-proprietary format
  for debug builds
- `PdbOnly` generates a "non-portable" `pdb` file, a
  Windows-proprietary format for release builds
- `Portable` generates a "portable" pdb file, which is the new
  standard that works for debug and release builds. New SDK-style
  MSBuild projects use this option by default.

These values are not case sensitive, I have mostly seen them lower
case in newer projects.

So what does Xamarin.Forms need to do?

Use `<DebugType>portable</DebugType>` in any Android class library or
app project. Other platforms, this is optional, not as much benefit. I
have heard that `DebugType=portable` might cause a problem on UWP.

* Xamarin.Forms will ship "portable" `pdbs` in its NuGet package for
  `FormsViewGroup.dll` and `Xamarin.Forms.*.Android.dll`. Developers
  won't pay the 100ms on initial build.
* Initial build times for `Xamarin.Forms.sln` will be slightly better
  for development, although I didn't measure the difference here.

* [XamlC] fix the argument match check for events (#4134)

Well, it looks like the order of arguments of InheritOrImplements was
reversed... a totally fine and normal Friday so far

- fixes #4130

* Add UI Test. Add instructions. Move to correct namespace (#4170) fixes #2251

* Add uitest for 2794 (#4110) fixes #2293

* Fix PropagateEvent value properly on Cells (#4191)

* bump gitinfo

* [Core, iOS, MacOS, Android, UWP, WPF] ListView hide scroll view scroll bars (#3897) fixes #3843

* Update from origin (#8)

* [C] VisibilityConverter Trims input (#3581)

For CSS purposes, the VisibilityConverter was added, and actually
replaced the `Boolean.Parse(str)` call for parsing Visibility.
`Boolean.Parse()` trims input, and the converter was not, so this was a
regression.
This changes Trim() the input, to be fully backward compatible.

- fixes #3554

* [C] avoid AmbiguousMatchexception in Bindings (#4216) fixes #4215

if a type defines multiple op_implicit from the same type to different
ones, trying to retrieve it with GetMethod() throws an
AmbiguousMatchException. If this happens, we have to do the resolution
ourself.

* Update from origin (#8)

* [C] VisibilityConverter Trims input (#3581)

For CSS purposes, the VisibilityConverter was added, and actually
replaced the `Boolean.Parse(str)` call for parsing Visibility.
`Boolean.Parse()` trims input, and the converter was not, so this was a
regression.
This changes Trim() the input, to be fully backward compatible.

* [msbuild] use portable pdb files (#4201)

Currently, on the first build of a "Hello World" Xamarin.Forms app,
you will see this in the build log:

    ConvertDebuggingFiles
        Parameters
            Files
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\FormsViewGroup.pdb
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\Xamarin.Forms.Platform.Android.pdb
        OutputItems
            _ConvertedDebuggingFiles
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\FormsViewGroup.dll
                C:\Users\myuser\.nuget\packages\xamarin.forms\3.1.0.697729\lib\MonoAndroid10\Xamarin.Forms.Platform.Android.dll

The logging is a little weird here, but this `ConvertDebuggingFiles`
MSBuild task takes about 100ms on my machine.

What is it doing?

The Mono debugger can support two types of debugging files:
- `mdb` files
- "portable" `pdb` files

If Xamarin.Android's build finds a "non-portable" `pdb` file, we have
to run it through this task to convert to an `mdb` file... This gives
us proper stacktraces for `FormsViewGroup.dll` and
`Xamarin.Forms.Platform.Android.dll`.

You can change the type of debugging symbols in your project with the
`DebugType` setting, which has these options:
- Blank or `None`: don't generate symbols. (Although Xamarin.Android
  has funny behavior here, see:
  https://github.com/xamarin/xamarin-android/issues/2282)
- `Full` generates an `mdb` file, this is a Windows-proprietary format
  for debug builds
- `PdbOnly` generates a "non-portable" `pdb` file, a
  Windows-proprietary format for release builds
- `Portable` generates a "portable" pdb file, which is the new
  standard that works for debug and release builds. New SDK-style
  MSBuild projects use this option by default.

These values are not case sensitive, I have mostly seen them lower
case in newer projects.

So what does Xamarin.Forms need to do?

Use `<DebugType>portable</DebugType>` in any Android class library or
app project. Other platforms, this is optional, not as much benefit. I
have heard that `DebugType=portable` might cause a problem on UWP.

* Xamarin.Forms will ship "portable" `pdbs` in its NuGet package for
  `FormsViewGroup.dll` and `Xamarin.Forms.*.Android.dll`. Developers
  won't pay the 100ms on initial build.
* Initial build times for `Xamarin.Forms.sln` will be slightly better
  for development, although I didn't measure the difference here.

* [C] VisibilityConverter Trims input (#3581)

For CSS purposes, the VisibilityConverter was added, and actually
replaced the `Boolean.Parse(str)` call for parsing Visibility.
`Boolean.Parse()` trims input, and the converter was not, so this was a
regression.
This changes Trim() the input, to be fully backward compatible.

regression.
This changes Trim() the input, to be fully backward compatible.
