ask for set up workaround to make AOT works #226

Closed guillaume-chervet closed 8 months ago

guillaume-chervet commented 8 months ago

Hi @sakno,

Thank you again for your awesome work !

SlimFaas now work in full Trim mode. But, now when I try to switch to AOT compilation I have an error at runtime (during startup). I would like to compare TRIM mode and AOT, because the lowest RAM usage is my priority.

I have the error bellow at runtime that you say it is linked to deletage constructor in discussion : https://github.com/dotnet/dotNext/discussions/200

Thank you a lot for your help !

There is explanation of why it doesn't work: https://github.com/dotnet/runtime/issues/94977#issuecomment-1818184343. Therefore, it's actually an issue with AOT infrastructure. However, in this case there is a cheap workaround.

sakno commented 8 months ago

This is why this issue considered as enhancement rather than bug.

guillaume-chervet commented 8 months ago

Thank you so much @sakno for your commit !

I can't wait for the next release :)

guillaume-chervet commented 8 months ago

It works very well, thank you so much @sakno

There is a big difference in used RAM once AOT is activated.
