[PATCH v3 0/4] MR1635: jscript: Implement a Garbage Collector to deal with circular references.
by Gabriel Ivăncescu Dec. 5, 2022

Dec. 5, 2022

Implement a basic GC based on the mark-and-sweep algorithm, without requiring manually specifying "roots", which vastly simplifies the management. For now, it is triggered every 30 seconds since it last finished, on a new object initialization. Better heuristics could be used in the future. The comments in the code should hopefully understand the high level logic of this approach without boilerplate details. I've tested it on FFXIV launcher (along with other patches from Proton to have it work) and it stops the massive memory leak successfully by itself, so at least it does its job properly. The last patch in the MR is just an optimization for a *very* common case. For artificial testing, one could use something like: ```javascript function leak() { var a = {}, b = {}; a.b = b; b.a = a; } ``` which creates a circular ref and will leak when the function returns. It also introduces and makes use of a "heap_stack", which prevents stack overflows on long chains. -- v3: jscript: Create the source function's 'prototype' prop object on demand. jscript: Run the garbage collector every 30 seconds on a new object jscript: Implement CollectGarbage(). jscript: Implement a Garbage Collector to deal with circular references. https://gitlab.winehq.org/wine/wine/-/merge_requests/1635

[PATCH 0/1] MR1685: wine.inf: Register winprint print processor.
by Piotr Caban (＠piotr) Dec. 5, 2022

Dec. 5, 2022

I'm not sure what's the best way of registering print processor. The alternative is to register winprint in winspool when driver is added. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1685
