- Move the "world directory" getter out of the proxy - we can just use
Forge's code here.
- Remove the server proxies, as both were empty. We don't tend to
register any dedicated-server specific code, so I think we can leave
them out.
- 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 will hopefully make it easier to track down various issues which
might otherwise go unnoticed or provide little information.
The main areas modified are those that external APIs may provide values
for or interact with: various providers and ILuaObject/IPeripheral
implementations. However, we do also log in a couple of other places
which indicate a problem with this, or another, mod.
