This commit removes the old version checker that used the DBO resource
page and replaces it with a custom checker that uses the "legacy" Spigot
resource API. The Spigot API is much more lightweight and doesn't
require any sort of parsing.
The new version checker uses a simple cache, keeping version checks
fresh for up to one hour, reducing the need to go fishing on every op
login. The cache resets on restarts, though, but this is acceptable.
Note that no attempt has been made to ensure correctness on multiple,
consecutive invocations when the cache is stale. If a cache refresh is
initiated, all update checks invoked before the cache refresh has ended
will behave as if no update is available. This is acceptable, because
update checks are non-essential, the time frame is extremely narrow, and
the most common result of an update check is "no updates available",
since the amount of update checks made is vastly greater than the amount
of updates released.
The whitelisting approach works well for the legacy builds, because the
version landscape doesn't change with those. However, the main build on
the master branch will not run on a server version other than 1.13, so
come 1.14, MobArena will be broken.
This commit fixes this problem by changing to a blacklisting approach
for the main build on the master branch. Checking for versions that the
build *can't* run on brings back MobArena's old resilience to version
changes on the Minecraft side of things.
This commit changes how the ThingParser is used throughout the code base. Instead of blindly filtering out null values, we're now throwing a new InvalidThingInputString exception. This exception is caught in an outer scope that has more context. The exception is then unwrapped and rethrown as a ConfigError with the additional context. In the outermost scope of (re)loading the config-file, the ConfigError is caught and printed, and then (re)loading stops gracefully.
We still need a proper way to handle loads/reloads consistently to get rid of the default command usage message, but this is a good step towards better usability in the face of user errors.
Fixes#478
This commit introduces the PermissionThing and associated parser. The parser determines the value (grant/revoke) of the permission by looking at the first character of the input string - if it is a minus (-) or caret (^), the value is false (revoke), otherwise it is true (grant). To distinguish permissions from other things, the parser requires a prefix of "perm:".
The ability to execute commands by hitting signs is already implemented by other plugins, but by creating built-in support for such signs, it's possible to leverage information about the plugin and its current state. This implementation allows for displaying live information about player counts, waves, etc. on the signs in addition to tying actions to them.
Customizable templates defined in the new signs.yml config-file can be bound to signs during the in-game sign creation, and users can define state-specific templates that change based on whether an arena is completely idle, has players in the lobby, or is running and in full swing.
Sign data is stored in data/signs.data as a YAML-formatted file that shouldn't be modified directly, effectively separating configuration (templates in signs.yml) and data (coordinates and parameters in signs.data).
Closes#385
Changes the "Vault was not found" message in Vault setup to INFO instead of WARNING, because this configuration isn't actually necessarily a warning sign. Parsing a money thing with no economy is, however. MoneyThingParser logs at ERROR level if Vault or an economy plugin isn't found, but a money thing is parsed.
This also swaps out the dependency on mockito-all with mockito-core, which is actually maintained. The purpose of updating is to allow for new Mockito features, such as mocking final methods, which happens due to the test resource org.mockito.plugins.MockMaker.
It turns out that the method reference on MobArena#getEconomy() in ThingManager is a tight enough dependency on Vault's Economy interface that it results in a NoClassDefFoundError if Vault isn't present.
By resorting to a more "naive" approach of resolving the Economy instance from the main plugin class on every parse call in MoneyThingParser, the NoClassDefFoundError is avoided along with the load/enable ordering issue that was fixed with the lazy-fetching in commit 2fcb20b2ae.
This reverts 2fcb20b2ae and partly 4c34a183c7.
Fixes#463
The eager loading results in nothing but nulls because ThingManager (and, by proxy, MoneyThingParser) is instantiated on load, while the Economy provider from Vault is fetched on enable.
The bug was introduced with 4c34a183c7.
This fixes#451
This means that MoneyThingParser now needs to pass along an Economy instance instead of a MobArena instance, which makes the dependency a little more focused and reasonable.
Also adds MoneyThingParser tests.
Swaps out the hard dependecy on ItemStack for class armor, such that the ThingManager - and thus every ThingParser registered within - has a chance at providing "armor" for a class.
To distinguish armor from items, ArenaMasterImpl prepends "armor:" or slot-specific prefixes to these values before passing them to the ThingManager. This makes it possible to distinguish between items and armor on the thing parser end if applicable - it doesn't make sense for money and command parsers, but they will just end up skipping these values.
The ItemStackThingParser is given a bit of an overhaul. It now depends internally on ItemStack parsers, which can be registered via the ThingManager. This allows custom plugins to hook into the ItemStack-specific part of the ItemStackThingParser to avoid having to duplicate code. Plugins that just want to provide ItemStacks can use this parser approach, and plugins that want to provide more abstract Things can use the Thing parser approach.
With CommandThing and its parser, it is now possible to use commands anywhere a thing can be used. Commands are invoked as the console/server, and they support a single variable, the name of the recipient player.
Commands are give-only, meaning they will fail to be "taken" from players, and they cannot be "held" either. The idea of commands as things basically only makes sense in the context of rewards.
