[0.12.12] [cube] pcall behavior changed

Post by gheift »

When using pcall to catch exceptions, factorio crashes with

Code: Select all

2015-10-21 10:43:20; Factorio 0.12.12 (Build 17122, linux64)
Operating system: Linux
[…]
terminate called after throwing an instance of 'ScriptException'
terminate called recursively

Example code in control.lua:

Code: Select all

local ok, mod = pcall(require, "does_not_exist")
In 0.12.11 this works, in 0.12.12 it does not.

Nothing changed with pcall in 0.12.12. In fact pcall still works perfectly in 0.12.12. I use it in my Landfill mod and it works perfectly (just tested).

Something is wrong with the code you've provided. Can you post a full working script that I can run to reproduce the issues you're having that works in 0.12.11 and doesn't work in 0.12.12?

Edit: from what you've posted that's not the correct syntax for pcall: http://www.lua.org/pil/8.4.html
If you want to get ahold of me I'm almost always on Discord.

I have created a minimal mod, which crashes my 0.12.12, but not my 0.12.11.

control.lua:

Code: Select all

local ok, mod = pcall(require, "does_not_exist")
The output on starting a new game:

Another test case, which crashes the new version:

Code: Select all

local ok, mod = pcall(function()error"foo"end)

I just copy/pasted the call from deflatelua, but it is indeed correct syntax: http://www.lua.org/manual/5.1/manual.html#pdf-pcall

Can't reproduce – I can start a new game with your testcase mod just fine. Can you download a fresh zip of 0.12.12 and test it with that? I suspect the updater might have broken something for you.

Pardon me my intrusion into this technically elevated talk, but is pcall supposed to crash because of this:

Code: Select all

/c pcall(true)
?
This only happens on 0.12.12 (both fresh download and update)
crashlog
I do mods. Modding wiki is friend, it teaches how to mod. Api docs is friend too...
I also update mods, some of them even work.
Recently I did a mod tutorial.

There's definitely something wrong with the Linux release build. We're looking into it.

This particular issue doesn't happen on the Windows release build (which is what I've been testing with).
If you want to get ahold of me I'm almost always on Discord.

Might be unrelated - I got an error posted for RSO when one of files fails to parse.
I can't reproduce it on my windows machine but there was some strange part in there (value was written as 0,4 not 0.4).
Is it possible it's related to this?

Yes. What would normally give a nice "script error" output and exit to the main menu is causing a full crash on the Linux release build.

It's a bit different here. It doesn't error out at all on windows build. It was parsing till now without any errors at all. And it still is for windows build.
It produced syntax error on linux(my assumption) thats visible here:

As far as I can see that code was there from August.

Thanks for the report (and all the ones I marked as duplicate :-) ), these problems should be fixed for 0.12.13.

I changed our build to use link time optimizations, but it looks that the toolchain still has some bugs :-). In this case it caused the 0.12.12 to immediately terminate after an exception was thrown instead of catching it properly.
