This is a horrible commit: It's a breaking change in a pretty subtle
way, which means it won't be visible while updating. Fortunately I think
the only mod on 1.19.4 is Plethora, but other mods (Mek, Advanced
Peripherals) may be impacted when they update. Sorry!
For some motivation behind the original issue:
The default IArguments implementation (VarargArguments) lazily converts
Lua arguments to Java ones. This is mostly important when passing tables
to Java functions, as we can avoid the conversion entirely if the
function uses IArguments.getTableUnsafe.
However, this lazy conversion breaks down if IArguments is accessed on a
separate thread, as Lua values are not thread-safe. Thus we need to
perform this conversion before the cross-thread sharing occurs.
Now, ideally this would be an implementation detail and entirely
invisible to the user. One approach here would be to only perform this
lazy conversion for methods annotated with @LuaFunction(unsafe=true),
and have it be eager otherwise.
However, the peripheral API gets in the way here, as it means we can no
longer inspect the "actual" method being invoked. And so, alas, this
must leak into the public API.
TLDR: If you're getting weird errors about scope, add an
IArguments.escapes() call before sharing the arguments between threads.
Closes#1384
- Fix several inaccuracies with several files not marking Dan's
authorship. Most of these are new files, where the code was moved from
somewhere else:
- In the public API: IDynamicLuaObject, ILuaAPI, TaskCallbakc,
IDynamicPeripheral, UpgradeBase
- In the ROM: fs, http, require
- Do not mark Dan as an author for entirely new code. This affects
DetailHelpers, DropConsumer, FluidData, InventoryMethods, ItemDetails,
MonitorRenderState, NoTermComputerScreen, Palette, PlatformHelperImpl,
UploadFileMessage, the Terminal tests, and any speaker-related files.
- Relicence many files under the MPL where we have permission to do
so. See #1339 for further details.
Thank you to everyone who has contributed so far! Cannot overstate how
appreciated it is <3.
Trying to play a non-DFPWM (or WAV) file will generate terrible noise,
which in turns generates confused users. Instead, fail to play the audio
file and redirect them to the docs.
- Consult __name in native code too. Closes#1355. This has the added
advantage that unconvertable values (i.e. functions) will now
correctly be reported as their original type, not just nil.
- Fix the error message in cc.expect, so it matches the rest of Lua.
This has been bugging me for years, and I keep forgetting to change
it.
- Several files where @MCJack123 is the exclusive contributor. He has
signed over all contributions to "any OSI-approved license". Thank
you!
- Various the file handle classes: Looking at these again, I don't
think they contain any of the original code.
- Timeouts are now driven by an interrupt system, rather than polling.
While we do not impose memory limits, this should close#1333.
- Update the table library to largely match Lua 5.4:
- Add table.move
- Table methods (with the exception of foreach/foreachi) now use
metamethods (closes#1088).
There's still some remaining quirks (for instance, table.insert
accepts values out-of-bounds), but I think that's fine.
- Cobalt's threaded-coroutine system is gone (load now supports
yielding), so we no longer track coroutine metrics.
- Type errors now use __name. See #1355, though this does not apply to
CC methods (either on the Java or CraftOS side), so is not enough to
resolve it.
See https://github.com/SquidDev/Cobalt/compare/v0.6.0...v0.7.0 for the
full delta.
This adds SPDX license headers to all source code files, following the
REUSE[1] specification. This does not include any asset files (such as
generated JSON files, or textures). While REUSE does support doing so
with ".license" files, for now we define these licences using the
.reuse/dep5 file.

See the discussion in #1352 - Netty uses the system one by default,
so no sense creating our own.
Also make sure we through the HTTP error every time, not just on the
first failure. Otherwise we get cryptic connection dropped errors.
Given an input like f(x), which is both a valid statement and
expression, both parsers would accept the whole input. However, this was
treated the same as both parsers rejecting the input, resulting in a
crash when trying to print the error.
We now return immediately when any parser accepts the input.
Fixes#1354
If someone had a recursive table (created with an IIFE), then we'd throw
an error inside reserialize. We now catch this error and silently drop
the value.
I'm not thrilled by this behaviour - there's an argument we should
return false instead - but it's consistent with what we currently do.
Closes#1337.
Previously it was possible to access all methods of the multishell
redirect by calling term.current(). This is definitely not intended, as
it leaks all sorts of internals to the user.
Also bump illuaminate - the new version is about twice as fast on my
machine.
Woops!
- Fix the REPL not printing values, as exception.try didn't return
values. It did originally, and then I tried to simplify it >_>
- Change repl_exprs to run an expression and program parser in
parallel, rather than handling the parallelism on the grammar side -
that has a few shift/reduce conflicts which result in bad parse
errors.
- Bump Cobalt to 0.6.0. We now track both line and column numbers of
each bytecode instruction, allowing us to map an error to a concrete
position.
- `loadfile` (and similar functions) now use the full path, rather than
the file name. Cobalt truncates this to 30 characters (rather than
the previous 60) so this should be less noisy.
- The shell, edit and Lua REPL now display the corresponding source
code alongside an error.
Note this is incredibly limited right now - it won't cope with errors
which cross coroutine boundaries. Supporting this is on the roadmap,
but requires some careful API design.
- Encode the DFA as a virtual machine (identical to lrgrep) rather than
compiling it to a series of Lua functions. While this is a little
slower and uglier, it's much more space efficient, shaving off 16Kb.
- Minimise the DFA properly. This only shaves off a few states, but
every little helps.
- Run the error handling code from a non-reduced parser stack. This was
incredibly nasty to get right (and positions are still not correctly
handled), but it fixes several broken error messages.
- Move modem recipes out of the usage section.
- Add missing argument names to BinaryWriableHandle.write. Illuaminate
really should catch this, but for now I did a grep and couldn't find
any more instances of this.
- Add several (internal) modules for lexing and parsing Lua code. These
allow us to provide (hopefully) higher quality error messages than
Lua's built-in messages.
- `shell.run`, `edit` and `lua` now use this parser when fed invalid
code. This allows us to provide better syntax errors, while not
having any impact on the happy path.
Note this does not affect any other mechanism for loading code
(`load`, `require`, `dofile`).
There's still a lot of work to do here in improving error message
quality, but hopefully this provides a good starting point.
Just ran[^1] over the codebase. Turns out we'd duplicated one of the
changelog entries entirely - I suspect due to a version merge gone
wrong!
