RFR: Fix SCCache closing races
by Aleksey Shipilev 05 Sep '24

05 Sep '24

I have been scratching my head why Leyden builds crash with multiple iterations of `HelloStream` example. The crashes are of various shapes, but they have a similar clue: it happens when we touch `SCCache` when it was already closed: `hs_err` shows we have called `before_exit`, `gdb` shows `SCCache::_cache` is already `nullptr`, but the crashes are in compiler code that accesses `SCCache`. Looking at `SCCache` closing code, I found two major bugs: 1. For cache writer side, we piggyback on `Compile_lock` to abitrate the access to maybe-closing cache. That does not work: in `ciEnv::register_method`, we already have `SCEntry*` in our hands, and once we acquire the `Compile_lock`, the whole `SCCache` might be gone, `SCEntry*` points to garbage, and we SEGV. This one is easy to solve: check that cache is still on, under the lock. 2. For cache reader side, we have a `reading_nmethod` counter, which is supposed to track how many nmethod readers are currently active. Unfortunately, this is still racy: nothing prevents new nmethod readers to appear _"after"_ we closed the cache. So those nmethod readers can access the cache in invalid state. There is also piggybacking on `Compilation_lock`, which AFAICS is for WhiteBox paths! So this is not great. I replaced the whole thing with carefully tracking the nmethod reader counts, and making sure we have the phasing right. Eliminating `Compilation_lock` wait improves performance and variance on short workloads as well.
