lib,src: support values > 4GB in heap statistics #10186
Conversation
Forgot to mention, I didn't add a test because I don't think I can make it reliable. It only works on 64 bits architectures and even there preallocating too much address space might lead to a run-in with the OOM killer. |

We were transporting the heap statistics as uint32 values to JS land but those wrap around for values > 4 GB. Use 64 bits floats instead, those should last us a while.

Hi, This is a crucial fix for us. When is this going to make it into an LTS release? Thank you! Tamas |
@tamasmahr Unfortunately, this first has to live in a v7.x release for two weeks before it will be included in an LTS release, so it might still take a bit. :/ |

It seems this is still not implemented or half-implemented/tested. Record Allocation Timeline inside inspector can't be displayed properly because if this or something related to this fix. |

Thank you. I have noticed, that CPU profiling is not working as well. I these issues are related or i should open new issue? |
