Also move mods/ to data/mods/
This makes PS more monorepo-like. The intent is to further separate
the sim and the server code, but without fully committing to splitting
the repository itself.
We now support `./pokemon-showdown start` in addition to
`./pokemon-showdown`. I'm not clear which I want to be the default
yet.
Useful for local testing, ignores matchmaking conditions like "can't
match same player twice in a row" and "can't match same IP", to make
it easier to test ladder stuff.
Process Manager is now lib/process-manager.js
It's been entirely rewritten to reflect what I think a process manager
API should look like.
In particular, there are now two Process Managers, QueryProcessManager
and StreamProcessManager.
Pass QueryProcessManager a pure-ish query function (sync or async) that
takes a JSON value and returns a JSON value, and PM.query() will
execute that function in a subprocess, and return a Promise for its
return value.
StreamProcessManager is the same idea: Pass it a function to create an
ObjectReadWriteStream, and PM.createStream() will create a stream in a
subprocess and return a stream connected to it.
The new FS module is an abstraction layer over the built-in fs module.
The main reason it exists is because I need an abstraction layer I can
disable writing from. But that'll be in another commit.
Currently, mine is better because:
- paths are always relative to PS's base directory
- Promises (seriously wtf Node Core what are you thinking)
- PS-style API: FS("foo.txt").write("bar") for easier argument order
- mkdirp
This also increases the minimum supported Node version from v6.0 to
v7.7, because we now use async/await. Sorry for the inconvenience!
This also drops the mock-fs-require-fix dependency
mock-fs-require-fix was always kind of a huge hack. It's no longer
necessary, with an FS API that does everything it used to.
This removes a lot of other hacks from test/main.js, which is nice.
- The before hook in test/main.js has no reason to be handled
asynchronously when nothing it handles is async
- test/simulator/index.js has no reason to exist when mocha.opts
already handles finding files to test
This enables battles in tests to reset their RNG to what it originally
was when they were created. A number of tests do this already by
breaking encapsulating and modifying the prng variable directly. This
should fix that.
We also remove createBattleWithPRNG and min/maxSeed properties.
Firstly, the tests that were still using the maxSeed property were
setting it to Battle.seed which has no effect since the PRNG class does
not look at this property any more - so these were no-ops.
After removing this property from tests, maxRollSeed was never used, so
I removed it and renamed minRollSeed to DEFAULT_ROLL_SEED (since it's
constant).
The places that were still using minRollSeed also were no-ops or were
using createBattleWithPRNG. Since every single instance was actually
just using the same code, I removed createBattleWithPRNG and made
createBattle default to giving you a seed with DEFAULT_ROLL_SEED and
removed the minRollSeed property too.
This makes tests much simpler and reduces the usage surface of
TestTools; now, you must define your *own* seed if you're making a PRNG
for a test, or you use one that TestTools gives you; you may not use a
public property that TestTools gives you.
We also remove the code that removes a listener in the Battle Engine.
This was rendered obsolete by f6a7c4b (see more info [in the discussion
on github][disc]

This removes the 'deterministic test' tools by preventing action at a
distance (namely, preventing the modification of the `init` method in
`Battle` during tests). This action at a distance is incredibly
confusing.
All this action at a distance did was discard any parameters that were
passed to `Battle` that weren't the first three (which was probably a
mistake by the original author) and also hard code `this.seed` and
`this.startingSeed` in `Battle`.
This functionality has now been moved to the `PRNG` class, so instead
users should pass a `PRNG` to `Battle` as the 5th constructor argument.
Users can also pass one as the third argument to `common.createBattle`
or use `common.createBattleWithPRNG` with the PRNG as the first
argument.
The PRNG is just an encapsulation of the pseudo-random algorithm in a
class. It is stateful, so make sure to take a `clone()` of the PRNG if
you want to re-use it.
simulator.js doesn't actually contain the simulator, but is really just
an implementation of battles in the RoomGame interface.
Renames:
`Simulator.Battle` -> `Rooms.RoomBattle`
`Simulator.BattlePlayer` -> `Rooms.RoomBattlePlayer`
`Simulator.SimulatorManager` -> `Rooms.SimulatorManager`
`Simulator.SimulatorProcess` -> `Rooms.SimulatorProcess`
`Simulator.create` -> no longer exists, use `new Rooms.RoomBattle(...)`
Now that nodejs/node#3072 is mostly fixed, we can finally start using
Node 4+ features.
This refactor:
- uses arrow functions where appropriate
Note that arrow functions still aren't used in Mocha, where `this`
is sometimes meaningful.
This also removes the need for .bind() nearly everywhere, as well
as the `self = this` trick.
- refactors Validator and Connection into ES6 classes
- no longer uses Array#forEach for iterating arrays
We strongly prefer for (let i = 0; i < arr.length; i++) because of
performance reasons. Most forEaches have been replaced with for..of,
though, which is 5x slower than the long-form loop but 2x faster
than forEach, which is good enough outside of most inner loops.
The only exception is tournaments, which is due for a more invasive
refactor soon anyway.
Previously, include('./sockets.js') and include('./app.js') would
automatically spawn listener processes.
Now, you have to actually use .listen() to spawn listener processes.
This makes the testing framework simpler, since it no longer needs an
ugly hack to suppress spawning socket processes, and also makes it
easier for the ./pokemon-showdown "binary" to pass a port to app.js.
./pokemon-showdown will now also install dependencies if necessary.
