Squirrel can stack overflow when GCing deep structures, leading to crash #7513

SamuXarick · 2019-04-14T21:32:12Z

Version of OpenTTD

1.9.1

Expected result

crash with a dump/not crash

Actual result

OpenTTD closes itself without a dump.

Steps to reproduce

Configure one NoCAB v499 to start.
Set up opcodes to 250000 to speed things up.
Start a 4096x4096 map with high number of towns and industries.
Wait for no more than 30 minutes, for a crash/poof.

debug build x64 gives me this.

SamuXarick · 2019-04-14T22:57:25Z

When trying this with monthly autosaves , it seems to be more prevalent.

SamuXarick · 2019-04-15T00:02:40Z

Crash without autosaving:

Seems AI creates too many and too big arrays (but expected with this map size and the number of towns and industries I guess).

So we need to memory limit squirrel. I started a patch but didn't get too far, perhaps I should revisit.

nielsmh · 2019-04-15T10:10:50Z

Squirrel is a bit annoying in that it doesn't allow using a stateful per-VM memory allocator. You can add some logic to the allocator functions to keep track of the total allocation size of all Squirrel VMs, but that won't help limiting each AI or GS, or detect which one is having the biggest impact.

I explored letting it use a stateful allocator (e.g. arena allocator) and it will involve touching lots of Squirrel internals.

PeterN · 2019-04-15T10:19:18Z

As each VM is run serially, not concurrently, an allocator can be told which VM is currently running. It makes running VMs concurrently unfeasible but I think that is already the case.

JGRennison · 2019-04-15T11:24:35Z

Using recursion for GC marking is problematic even if the total memory allocation is limited.
Data structures like linked lists or unbalanced trees can use up an excessive amount of stack even if their total size is quite modest.
Mark and sweep implementations usually use queues or sets rather than the stack to avoid this.

See also #6322, which is not the same issue, but similar area.

Attached is a bespoke AI that triggers this issue way sooner, usually in the first few days of it running instead of having to wait very long.

When OpenTTD 1.11.0 stable or OpenTTD 2021-04-14 nightly crashes from running the above AI, crash.dmp is generated with a file size of 0 bytes. crash.log and crash.png are not generated.

When OpenTTD jgrpp-0.41.0 crashes from running the above AI, crash.dmp, crash.log, and crash.png are generated as usual: crash-jgrpp-0.41.0.zip
