OK, so let's get this out of the way, there's some actual changes mixed
in here too. I'm really sorry:
- Turtles can now not be renamed with unnamed item tags (previously it
would clear the name, this seemed a little unideal).
- commands.getBlock(s)Data will also include NBT.
Now, onto the horror story which is these inspection changes:
- Make a lot of methods static
- Typo fixes
- Make utility classes final + private constructor
- Lots of reformatting (ifs -> ternary, invert control flow, etc...)
- ???
- Profit!
I'm so going to regret this - can pretty much guarantee this is going to
break something.
- Move all HTTP tasks to a unified "MonitoredResource" model. This
provides a uniform way of tracking object's lifetimes and disposing
of them when complete.
- Rewrite HTTP requests to use Netty instead of standard Java. This
offers several advantages:
- We have access to more HTTP verbs (mostly PATCH).
- We can now do http -> https redirects.
- We no longer need to spawn in a new thread for each HTTP request.
While we do need to run some tasks off-thread in order to resolve
IPs, it's generally a much shorter task, and so is less likely to
inflate the thread pool.
- Introduce several limits for the http API:
- There's a limit on how many HTTP requests and websockets may exist
at the same time. If the limit is reached, additional ones will be
queued up until pending requests have finished.
- HTTP requests may upload a maximum of 4Mib and download a maximum
of 16Mib (configurable).
- .getResponseCode now returns the status text, as well as the status
code.
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.
- Move the encoding/decoding from the Filesystem implementation to the
individual handles.
- Move each handle into an core.apis.handles package from the main fs
API.
- Move the HTTP response to inherit from these handles.
- Allow binary handles' read function to accept a number, specifying
how many characters to read - these will be returned as a Lua string.
- Add readAll to binary handles
- Allow binary handles' write function to accept a string which is
decoded into the individual bytes.
- Add "binary" argument to http.request and friends in order to return
a binary handle.
- Ensure file handles are open when reading from/writing to them.
- Return the error message when opening a file fails.
