Look, I originally had this split into several commits, but lots of
other cleanups got mixed in. I then backported some of the cleanups to
1.12, did other tidy ups there, and eventually the web of merges was
unreadable.
Yes, this is a horrible mess, but it's still nicer than it was. Anyway,
changes:
- Flatten everything. For instance, there are now three instances of
BlockComputer, two BlockTurtle, ItemPocketComputer. There's also no
more BlockPeripheral (thank heavens) - there's separate block classes
for each peripheral type.
- Remove pretty much all legacy code. As we're breaking world
compatibility anyway, we can remove all the code to load worlds from
1.4 days.
- The command system is largely rewriten to take advantage of 1.13's
new system. It's very fancy!
- WidgetTerminal now uses Minecraft's "GUI listener" system.
- BREAKING CHANGE: All the codes in keys.lua are different, due to the
move to LWJGL 3. Hopefully this won't have too much of an impact.
I don't want to map to the old key codes on the Java side, as there
always ends up being small but slight inconsistencies. IMO it's
better to make a clean break - people should be using keys rather
than hard coding the constants anyway.
- commands.list now allows fetching sub-commands. The ROM has already
been updated to allow fancy usage such as commands.time.set("noon").
- Turtles, modems and cables can be waterlogged.
- Some performance improvements to JEI recipe resolver
- Use a shared map for upgrade items, meaning we only need one map
lookup.
- Cache the basic upgrade recipes.
- Use the MC version within project rather than version name.
- Turtle and pocket computers provide a "creator mod id" based on their
upgrade(s).
We track which mod was active when the upgrade was registered, and
use that to determine the owner. Technically we could use the
RegistryLocation ID, but this is not always correct (such as
Plethora's vanilla modules).
- We show all upgraded turtles/pocket computers in JEI now, rather than
just CC ones.
- We provide a custom IRecipeRegistryPlugin for upgrades, which
provides custom usage/recipes for any upgrade or upgraded item. We
also hide our generated turtle/pocket computer recipes in order to
prevent duplicates.
This allows wireless modems (advanced and normal) to be used in
multiparts. There's a very limited set of uses for this (mostly allows
using Chisel and Bits with them), but it's very simple to do.
I'd like to look into MCMP support for wired modems/cables in the
future, but this will be somewhat harder due to their pre-existing
multiblock structure.
Similarly, might be fun to look into CBMP compatibility.
- Restrict what items can be inserted into printers. They're now closer
to brewing stands or furnaces: nothing can go in the output slot,
only ink in the ink slot, and only paper in the paper slot.
- Fix build.gradle using the wrong version
- Trim the width of tables to fit when displaying on the client. Closes
#45. Note, our solution isn't perfect, as it will wordwrap too, but
it's adaquate for now.
- Reword elements of the README, mostly changing the elements about
vanilla ComputerCraft.
- Change versioning scheme: we'll now do 1.x.y, with 1.81.0 being the
next version.
- Include MC version in the file name
- Stop bundling javadoc with the jar. We'll look into hosting this on
squiddev.cc if really needed.
- Remove the LuaJ license from the root - we no longer bundle the
sources, so it's not needed here.
I realise this change looks a little dodgey on its own, so see #113 for
the full rationale.
- Run optipng on all our images. This has very little effect on most of
them (as they're all so small anyway), but has resulted in a 50%
reduction in some cases.
- Run Proguard on our shadowed dependencies (Cobalt).
- Minify our JSON files, stripping all whitespace. This is mostly
useful for FML's annotation cache, as that's a massive file, but
still a semi-useful optimisation to make.
This has helped reduce the jar by about 110kb, which isn't much but
still feels somewhat worth it.
The latest version of Cobalt has several major changes, which I'm
looking forward to taking advantage of in the coming months:
- The Lua interpreter has been split up from the actual LuaClosure
instance. It now runs multiple functions within one loop, handling
pushing/popping and resuming method calls correctly.
This means we have a theoretically infinite call depth, as we're no
longer bounded by Java's stack size. In reality, this is limited to
32767 (Short.MAX_VALUE), as that's a mostly equivalent to the limits
PUC Lua exposes.
- The stack is no longer unwound in the event of errors. This both
simplifies error handling (not that CC:T needs to care about that)
but also means one can call debug.traceback on a now-dead coroutine
(which is more useful for debugging than using xpcall).
- Most significantly, coroutines are no longer each run on a dedicated
thread. Instead, yielding or resuming throws an exception to unwind
the Java stack and switches to a different coroutine.
In order to preserve compatability with CC's assumption about LuaJ's
threading model (namely that yielding blocks the thread), we also
provide a yieldBlock method (which CC:T consumes). This suspends the
current thread and switches execution to a new thread (see
SquidDev/Cobalt@b5ddf164f1 for more
details). While this does mean we need to use more than 1 thread,
it's still /substantially/ less than would otherwise be needed.
We've been running these changes on SwitchCraft for a few days now and
haven't seen any issues. One nice thing to observe is that the number of
CC thread has gone down from ~1.9k to ~100 (of those, ~70 are dedicated
to running coroutines). Similarly, the server has gone from generating
~15k threads over its lifetime, to ~3k. While this is still a lot, it's
a substantial improvement.
- Keep track of the number of created and destroyed coroutines for each
computer.
- Run coroutines with a thread pool executor, which will keep stale
threads around for 60 seconds. This substantially reduces the
pressure from short-lived coroutines.
- Update to the latest Cobalt version.
- Bump MinecraftForge version so we don't crash on load. Oh boy, all
the deprecation warnings.
- Inject IBundledEmitter and IBundledReceiver capabilities onto all
TileGenerics.
- Register a IBundledRedstoneProvider instance for IBundledEmitter.
This is a preliminary for updating to 1.13, as many of the name changes
apply to both. This will make it harder to remain consistent with
actual CC, though that will be less of a consideration when 1.13 hits.
- Add additional maven metadata and strip dependencies
- Shift ICommand registration into the proxy, to avoid class loading
issues. This is probably rather temperamental, but classloading
always is.
- Ensure pocket computers and turtles are distinguished by upgrades and
computer family.
- Ensure disks are distinguished by colour.
- Hide treasure disks from the list
- Convert most recipes to JSON
- Add JSON factories for impostor and turtle recipes.
- Several mappings changes
- Migrate to Forge's new registry system
Updated the source code to the version shipped as the 1.80pr0 alpha
release. Also removed some unnecessary files from the LuaJ subfolder
which were bulking up the repository.
