Before IPocketAccess.getEntity would return the entity which last held
fthis computer, even if not holding it any more. As
ba823bae13 describes, this caused
pocket.equip/pocket.unequip to dupe items.
We move the validation from the PocketAPI into the main IPocketAccess
implementation, to ensure this issue does not occur elsewhere. Note, we
require a separate method, as this is no longer thread-safe.
We also now return ok, err instead of throwing an exception, in order to
be consistent with the turtle functions. See dan200/ComputerCraft#328.
- Share the ILuaContext across all method calls, as well as shifting it
into an anonymous class.
- Move the load/loadstring prefixing into bios.lua
- Be less militant in prefixing chunk names:
- load will no longer do any auto-prefixing.
- loadstring will not prefix when there no chunk name is supplied.
Before we would do `"=" .. supplied_program`, which made no sense.
For instance, `pastebin run https://pastebin.com/LYAxmSby` will now
extract the code and download appropriately. Also add an error message
when we received something which is not a valid pastebin code.
See #134.
Before it was not actually selected until the task had yielded for the
first time. If a computer did not yield (or took a while to do so),
nothing would actually show up.
We now generate a table and concatinate the elements together. This has
several benefits:
- We no longer emit emit trailing spaces, which caused issues on 1.13's
command system.
- We no longer need the error level variable, nor have the weird
recursion system - it's just easier to understand.
This replaces the existing IMount openFor* method with openChannelFor*
ones, which return an appropriate byte channel instead.
As channels are not correctly closed when GCed, we introduce a
FileSystemWrapper. We store a weak reference to this, and when it is
GCed or the file closed, we will remove it from our "open file" set and
ensure any underlying buffers are closed.
While this change may seem a little odd, it does introduce some
benefits:
- We can replace JarMount with a more general FileSystemMount. This
does assume a read-only file system, but could technically be used
for other sources.
- Add support for seekable (binary) handles. We can now look for
instances of SeekableByteChannel and dynamically add it. This works
for all binary filesystem and HTTP streams.
- Rewrite the io library to more accurately emulate PUC Lua's
implementation. We do not correctly implement some elements (most
noticably "*n", but it's a definite improvement.
This crash can be triggered remotely by specially constructed rednet messages, making this a bit of a problem, as any repeaters can be remotely crashed.
- Make window.reposition's argument validation a little more strict.
Previously it would accept `window.reposition(x, y, width)` (no
height argument), just not act upon it.
- Use select instead of table.unpack within `pastebin run`.
- Use `parallel.waitForAny` instead of `waitForAll` within the dance
program.
- Pipe the entire help file into `textutils.pagedPrint`, rather than
doing it line by line.
- Remove bytecode loading disabling from bios.lua. This never worked
correctly, and serves little purpose as LuaJ is not vulnerable to
such exploits.
This implements an argument format similar to LuaReqeust, as described
in dan200/ComputerCraft#515. The Lua argument checking code is a little
verbose and repetitive, but I'm not sure how to avoid that - we should
look into improving it in the future.
Closes#21
- fixed circumflex typo: you can now cîrcûmflêx on all your friends
- added comment making it clearer that the following lines are intended for backwards compatibility.
