* Moves spawners and decals to a different init/delete scheme
Rather then fully creating and then immediately deleting these things,
we instead do the bare minimum.
This is faster, if in theory more fragile. We should be safe since any
errors should be caught in compile since this is very close to a
"static" action. It does mean these atoms cannot use signals, etc.
* Potentially saves init time, mostly cleans up a silly pattern
We use sleeps and INVOKE_ASYNC to ensure that handing back turfs doesn't
block a space reservation, but this by nature consumes up to the
threshold and a bit more of whatever working block we were in.
This is silly. Should just be a subsystem, so I made it one, with
support for awaiting its finish if you want to
* Optimizes garbage/proc/Queue slightly
Queue takes about 1.6 seconds to process 26k items right now.
The MASSIVE majority of this time is spent on using \ref
This is because \ref returns a string, and that string requires being
inserted into the global cache of strings we store
What I'm doing is caching the result of ANY \ref on the datum it's
applied to. This ensures previous uses will never decay from the string
tree.
This saves about 0.2 seconds of init
When I changed the syntax of SS13.lua to account for the ability to properly index tables with datums, it turns out that the callbacks created for signal handlers and timeouts had circular references, resulting in hard-deletes.
My first solution was to make it so signal handler and timeout callbacks use weakrefs, which get resolved in lua_state/call_function, but it turns out that, when calling the signal cleanup function, a qdeleted-but-not-yet-garbage-collected datum's weakref resolves to null because datum.gc_collected is set to GC_CURRENTLY_BEING_QDELETED before COMSIG_PARENT_QDELETING gets sent.
To resolve this issue, Potato and Oranges both recommended that I make a snowflake variant of resolve which ignores whether the datum a weakref points to is qdeleted - only that it is null or it's weakref isn't the very weakref resolve was called on. This proc was given a lengthy autodoc comment describing when it should or shouldn't be used, to ensure it is only used in cases similar to the one I needed to create it for (needing to resolve a weakref to a datum in a COMSIG_PARENT_QDELETING handler registered on that very datum).
When trying to run getFlatIcon using lua scripting, I discovered that it was so expensive that, for certain atoms like complex humans, there is no way it will complete within the lua execution limit. While Mothblocks would suggest just raising the execution limit, the idea leaves a bad taste in my mouth due to the possibility of a script causing extreme lag by consistently overrunning the BYOND tick.
I instead elected to make /datum/auxtools_promise sleep once before invoking its assigned proc, thus immediately returning execution to lua, even if the proc being awaited wouldn't sleep. This allows for awaiting extremely expensive non-sleeping procs (like the aforementioned getFlatIcon)
* preparations for self-referential list conversion
* additional changes for the auxlua 1.1.1 update
* fixed a type in `SS13.await`
* bumps auxlua to 1.2.0
* bumps auxlua to 1.2.1
Atomized from #68816, with a little addition. Fixes some dumb formatting issues with the lua editor, adds a "jump to bottom" button when viewing the state log, and paginates the state logs.
This PR fixes this issue by making sure every proc called in the stack of /proc/wrap_lua_print which could sleep is called using INVOKE_ASYNC, and to prevent such problems in the future, marks all the wrappers as SHOULD_NOT_SLEEP(TRUE). I also figured out how to fix the dumb overflowing problem of the lua editor ui.
Due to lag concerns regarding lua states with a large number of global variables (including fields within global tables), I have made it so the global table and state log are hidden by default - they can be shown using a toggle button in the editor ui.
