[Deadlock] ASImageNode.tintColor

[muukii]

Thank you for the great library.

And I've found a deadlock problem on ASImageNode.tintColor.
Let me issue about this.

I'm using Texture on 37e28300de631f38bb5420972ccc520e4e307d90

[muukii]

Does it relate?
#1617

[muukii]

Investigation Note:

I've tried to back to stable version (6176aa4)
Actuallly, I need above commit hash to support iOS13.
And, this commit hash works very well.

However, the deadlock caused after this PR #1617 merged.

So, maybe the code I wrote has some problems.
I would like to know some ideas or suggestions to avoid deadlocks.

For now, I continue using this hash (6176aa4).
If I get time, I try to investigate this again.

Thanks

@muukii - Can you share what's happening on the other threads? it looks like it might be occurring when trying to ascend the node hierarchy to find a tintColor

[muukii]

@rahul-malik
Thank you for your reply!

Ok! I will share the all of threads tomorrow.
I’ll be in touch!

I got the backtrace from lldb when it's breaking on dead-locking.
Let me know if you need other information!

@rahul-malik

Hi, I'm sorry to hurry.
Is there any progress?

[jparise]

#1732 is the proposed fix for this issue.

[muukii]

@jparise wow, thank you! I'll check!

[ernestmama]

Change is merged

[PatrickSCLin]

a quick question, when would this fixes be shipped with official release build ?
I might have same issue with this problem too, or which branch is stable to use ?
