- Don't treat turtles/pocket computers with no upgrades as an "any"
turtle. Otherwise getting the recipe of a crafty turtle shows the
recipe of a normal turtle too.
- Fix "get usage" of upgrade items not returning their recipes.
- Fix NPEs inside JEI (closes#719)
- Add remaining docs for the turtle API
- Add documentation for the fluid storage peripheral.
- Enforce undocumented warning for most modules (only io and window
remaining).
"Finish" in quotes, because these are clearly a long way from perfect.
I'm bad at writing docs, OK!
Fixes#701 (well, hopefully). Our BlockModelProvider is created when
running other mods' data generators (thought not run), which causes
issues as none of the models are considered as "existing files".
This is definitely going to break the build (it shouldn't, but these
things always do). Anyway...
- Use the new Java toolchain support, rather than requiring the user to
install multiple Java versions.
- Bump versions of several plugins.
We're sadly stuck on Gradle <7 for now, as they drop the old
maven-publish plugin, which drops SCP support.
We send monitor updates when a player starts watching a chunk. However,
the block/tile data has not been sent when this event is fired, and so
the packet is entirely ignored.
Instead, we now queue a "send this" task, which is then dispatched on
the next tick end.
I have memories of this working on 1.12, so either something changed in
an update or I'm a complete idiot. Both are possible.
Fixes#687
The replacement is objectively worse. However, it supports Git
worktrees, which sadly jgit does not.
We really need to rewrite the build script to make it lazy so we're not
executing these commands every time.
More importantly, `./gradlew check' actually runs the in-game tests,
which makes the CI steps look a little more sensible again.
Somewhat depressing that one of the longest files (15th) in CC:T is the
build script.
This probably fails "responsible disclosure", but it's not an RCE and
frankly the whole bug is utterly hilarious so here we are...
It's possible to open a file on a disk drive and continue to read/write
to them after the disk has been removed:
local disk = peripheral.find("drive")
local input = fs.open(fs.combine(disk.getMountPath(), "stream"), "rb")
local output = fs.open(fs.combine(disk.getMountPath(), "stream"), "wb")
disk.ejectDisk()
-- input/output can still be interacted with.
This is pretty amusing, as now it allows us to move the disk somewhere
else and repeat - we've now got a private tunnel which two computers can
use to communicate.
Fixing this is intuitively quite simple - just close any open files
belonging to this mount. However, this is where things get messy thanks
to the wonderful joy of how CC's streams are handled.
As things stand, the filesystem effectively does the following flow::
- There is a function `open : String -> Channel' (file modes are
irrelevant here).
- Once a file is opened, we transform it into some <T extends
Closeable>. This is, for instance, a BufferedReader.
- We generate a "token" (i.e. FileSystemWrapper<T>), which we generate
a week reference to and map it to a tuple of our Channel and T. If
this token is ever garbage collected (someone forgot to call close()
on a file), then we close our T and Channel.
- This token and T are returned to the calling function, which then
constructs a Lua object.
The problem here is that if we close the underlying Channel+T before the
Lua object calls .close(), then it won't know the underlying channel is
closed, and you get some pretty ugly errors (e.g. "Stream Closed"). So
we've moved the "is open" state into the FileSystemWrapper<T>.
The whole system is incredibly complex at this point, and I'd really
like to clean it up. Ideally we could treat the HandleGeneric as the
token instead - this way we could potentially also clean up
FileSystemWrapperMount.
BBut something to play with in the future, and not when it's 10:30pm.

All this wall of text, and this isn't the only bug I've found with disks
today :/.
Name a more iconic duo than @SquidDev and over-engineered test
frameworks.
This uses Minecraft's test core[1] plus a home-grown framework to run
tests against computers in-world.
The general idea is:
- Build a structure in game.
- Save the structure to a file. This will be spawned in every time the
test is run.
- Write some code which asserts the structure behaves in a particular
way. This is done in Kotlin (shock, horror), as coroutines give us a
nice way to run asynchronous code while still running on the main
thread.
As with all my testing efforts, I still haven't actually written any
tests! It'd be good to go through some of the historic ones and write
some tests though. Turtle block placing and computer redstone
interactions are probably a good place to start.

ForgeGradle (probably sensibly) yells at me about doing this. However:
- There's a reasonable number of mods doing this, which establishes
some optimistic precedent.
- The licence update in Aug 2020 now allows you to use them for
"development purposes". I guess source code counts??
- I'm fairly sure this is also compatible with the CCPL - there's an
exception for Minecraft code.
The main motivation for this is to make the Fabric port a little
easier. Hopefully folks (maybe me in the future, we'll see) will no
longer have to deal with mapping hell when merging - only mod loader
hell.
