Historically CC has supported two modes when working with file handles
(and HTTP requests):
- Text mode, which reads/write using UTF-8.
- Binary mode, which reads/writes the raw bytes.
However, this can be confusing at times. CC/Lua doesn't actually support
unicode, so any characters beyond the 0.255 range were replaced with
'?'. This meant that most of the time you were better off just using
binary mode.
This commit unifies text and binary mode - we now /always/ read the raw
bytes of the file, rather than converting to/from UTF-8. Binary mode now
only specifies whether handle.read() returns a number (and .write(123)
writes a byte rather than coercing to a string).
- Refactor the entire handle hierarchy. We now have an AbstractMount
base class, which has the concrete implementation of all methods. The
public-facing classes then re-export these methods by annotating
them with @LuaFunction.
These implementations are based on the
Binary{Readable,Writable}Handle classes. The Encoded{..}Handle
versions are now entirely removed.
- As we no longer need to use BufferedReader/BufferedWriter, we can
remove quite a lot of logic in Filesystem to handle wrapping
closeable objects.
- Add a new WritableMount.openFile method, which generalises
openForWrite/openForAppend to accept OpenOptions. This allows us to
support update mode (r+, w+) in fs.open.
- fs.open now uses the new handle types, and supports update (r+, w+)
mode.
- http.request now uses the new readable handle type. We no longer
encode the request body to UTF-8, nor decode the response from UTF-8.
- Websockets now return text frame's contents directly, rather than
converting it from UTF-8. Sending text frames now attempts to treat
the passed string as UTF-8, rather than treating it as latin1.
Wow, some of this is /old/. All the Maps.newHashMap stuff dates back to
Java 6, so must originally be CCTweaks code?!
We're unlikely to drop our Guava dependency (we use too much other
stuff), but we should make the most of the stdlib where possible.
- Add a new WebsocketClient interface, which WebsocketHandle uses for
sending messages and closing. This reduces coupling between Websocket
and WebsocketHandle, which is nice, though admitedly only use for
copy-cat :).
- WebsocketHandle now uses Websocket(Client).isClosed(), rather than
tracking the closed state itself - this makes the class mostly a thin
Lua wrapper over the client, which is nice.
- Convert Options into a record.
- Clarify the behaviour of ws.close() and the websocket_closed event.
Our previous test was incorrect as it called WebsocketHandle.close
(rather than WebsocketHandle.doClose), which had slightly different
semantics in whether the event is queued.
In this case, we use Lua's tostring(x) semantics (well, modulo
metamethods), instead of Java's Object.toString(x) call. This ensures
that values are formatted (mostly) consistently between Lua and Java
methods.
- Add IArguments.getStringCoerced, which uses Lua's tostring semantics.
- Add a Coerced<T> wrapper type, which says to use the .getXCoerced
methods. I'm not thrilled about this interface - there's definitely
an argument for using annotations - but this is probably more
consistent for now.
- Convert existing methods to use this call.
Closes#1445
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.
