Subject: Sync tests: test on_member_join

Should PUT user's data or POST it if the user doesn't exist.
ResponseCodeError should be re-raised if status code isn't a 404.
A helper method was added to reduce code redundancy between the 2 tests.

Subject: Tests: fix unawaited error for MockAPIClient

This error is due to the use of an actual instance of APIClient as the
spec for the mock. recreate() is called in __init__ which in turn
creates a task for the _create_session coroutine.

The approach to the solution is to use the type for the spec rather than
and instance, thus avoiding any call of __init__. However, without an
instance, instance attributes will not be included in the spec.
Therefore, they are defined as class attributes on the actual APIClient
class definition and given default values.

Alternatively, a subclass of APIClient could have been made in the
tests.helpers module to define those class attributes. However, it
seems easier to maintain if the attributes are in the original class
definition.

Subject: Use mixin-composition not inheritance for LoggingTestCase

We used inheritence to add additional logging assertion methods to unittest's TestCase class. However, with the introduction of the new IsolatedAsyncioTestCase this extension strategy means we'd have to create multiple child classes to be able to use the extended functionality in all of the TestCase variants.

Since that leads to undesirable code reuse and an inheritance relationship is not at all needed, I've switched to a mixin-composition based approach that allows the user to extend the functionality of any TestCase variant with a mixin where needed.

Subject: Use IsolatedAsyncioTestCase instead of async_test

Since we upgraded to Python 3.8, we can now use the new IsolatedAsyncioTestCase test class to use coroutine-based test methods instead of our own, custom async_test decorator. I have changed the base class for all of our test classes that use coroutine-based test methods and removed the now obsolete decorator from our helpers.

Subject: Remove lingering pytest test_time.py file

I forgot to remove one pytest test file during the migration from pytest to unittest. Since we have sinced added a unittest version of the same file, I've now removed the lingering pytest file.

Subject: Use unittest's AsyncMock instead of our AsyncMock

Python 3.8 introduced an `unittest.mock.AsyncMock` class that can be used to mock coroutines and other types of asynchronous operations like async iterators and async context managers. As we were using our custom, but limited, AsyncMock, I have replaced our mock with unittest's AsyncMock.

Since Python 3.8 also introduces a different way of automatically detecting which attributes should be mocked with an AsyncMock, I've changed our CustomMockMixin to use this new method as well. Together with a couple other small changes, this means that our Custom Mocks now use a lazy method of detecting coroutine attributes, which significantly speeds up the test suite.

Subject: Fix test_time test and ensure coverage

One of the test_time methods did not actually assert the exception message it was trying to detect as the assertion statement was contained within the context manager handling the exception. I've moved it out of the context so it actually runs.

I've also added a few `praga: no cover` comments for parts that were artifically lowering coverage of the test suite.

Subject: Use realistic mixin implementation

Instead of using the mixin class bare, I've now included into a class tha subclasses unittest.TestCase as that's how it's going to be used "in the wild".

The test suite for the new role/member syncers used the "old"-style test suite with the helpers implemented for Python 3.7. I have migrated it to use the new Python 3.8 asyncio test helpers.

Autospec supports using AsyncMocks in 3.8 so there's no need to rely on
a subclass of CustomMockMixin for the async mocks.

Subject: Use MagicMock as return value for _get_diff mock

The `_get_diff` method of TestSyncer class is mocked using an AsyncMock object. By default, when an AsyncMock object is called **and awaited**, it returns a child mock of the same time (another AsyncMock) according to the "the child is a like the parent" principle. This means that the _get_diff method will return an AsyncMock unless a different return_value is explicitly provided.

Because of that "child is like parent" behavior, this will happen in lines 194-196 of bot.cogs.sync.syncers (annotations added by me):

```
// `diff` will be a child AsyncMock as "child is like parent"
diff = await self._get_diff(guild)

// `diff._asdict` will be an AsyncMock as "child is like parent" and,
// after being called, it will return an unawaited coroutine object
// we assign the name `diff_dict`:
diff_dict = diff._asdict()

// `diff_dict` is still an unawaited coroutine object meaning that it
// doesn't have an `items()` method:
totals = {k: len(v) for k, v in diff_dict.items() if v is not None}
```

Original, unannotated: https://github.com/python-discord/bot/blob/c81a4d401ea434e98b0a1ece51d3d10f1a3ad226/bot/cogs/sync/syncers.py#L194-L196

This will lead to the following exception when running the tests:

```py
======================================================================
ERROR: test_sync_confirmation_context_redirect (tests.bot.cogs.sync.test_base.SyncerSyncTests) (ctx=None, author=<MockMember name='mock.user' spec_set='Member' id='140583452034864'>, message=None)
If ctx is given, a new message should be sent and author should be ctx's author.
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/sebastiaan/pydis/repositories/bot/tests/bot/cogs/sync/test_base.py", line 348, in test_sync_confirmation_context_redirect
    await self.syncer.sync(guild, ctx)
  File "/home/sebastiaan/pydis/repositories/bot/bot/cogs/sync/syncers.py", line 196, in sync
    totals = {k: len(v) for k, v in diff_dict.items() if v is not None}
AttributeError: 'coroutine' object has no attribute 'items'
```

The solution is to assign an explicit return value so the parent mock doesn't "guess" and return an object of its own type. I previously did that by providing a specific `_Diff` object as the return value, but I should have gone with a `MagicMock` to signify that it's not an important return value; it's just something that needs to support/mimic the API we use on it. So that's what this commit adds.

Subject: Migrate snekbox tests to Python 3.8's unittest

I've migrated the `tests/test_snekbox.py` file to use the new Python 3.8-style unittests instead of our old style using our custom Async mocks.

In particular, I had to make a few changes:

- Mocking the async post() context manager correctly

Since `ClientSession.post` returns an async context manager when called, we need to make sure to assign the return value to the __aenter__ method of whatever `post()` returns, not of `post` itself (i.e.. when it's not called).

- Use the new AsyncMock assert methods `assert_awaited_once` and `assert_awaited_once_with`

Objects of the new `unittest.mock.AsyncMock` class have special methods to assert what they were called with that also assert that specific coroutine object was awaited. This means we test two things in one: Whether or not it was called with the right arguments and whether or not the returned coroutine object was then awaited.

- Patch `functools.partial` as `partial` objects are compared by identity

When you create two partial functions of the same function, you'll end up with two different `partial` objects. Since `partial` objects are compared by identity, you can't compare a `partial` created in a test method to that created in the callable you're trying to test. They will always compare as `False`. Since we're not interested in actually creating `partial` objects, I've just patched `functools.partial` in the namespace of the module we're testing to make sure we can compare them.

 ### Mocking coroutines
 
-By default, the `unittest.mock.Mock` and `unittest.mock.MagicMock` classes cannot mock coroutines, since the `__call__` method they provide is synchronous.

 ### Special mocks for some `discord.py` types
 
 To quote Ned Batchelder, Mock objects are "automatic chameleons". This means that they will happily allow the access to any attribute or method and provide a mocked value in return. One downside to this is that if the code you are testing gets the name of the attribute wrong, your mock object will not complain and the test may still pass.
 
-In order to avoid that, we have defined a number of Mock types in [`helpers.py`](/tests/helpers.py) that follow the specifications of the actual Discord types they are mocking. This means that trying to access an attribute or method on a mocked object that does not exist on the equivalent `discord.py` object will result in an `AttributeError`. In addition, these mocks have some sensible defaults and **pass `isinstance` checks for the types they are mocking**.

 ### Test coverage is a starting point
 
-Having test coverage is a good starting point for unit testing: If a part of your code was not covered by a test, we know that we have not tested it properly.

Subject: Cog tests: add a function to get all commands

For tests, ideally creating instances of cogs should be avoided to avoid
extra code execution. This function was copied over from discord.py
because their function is not a static method, though it still works as
one. It was probably just a design decision on their part to not make it
static.

The first assert - `asyncio_mock.create_task.assert_called_once_with`

`send` on `alert_channel` was not tested properly because of a typo
 and a missing assert in the method call.

Subject: Set unsilence permissions to inherit instead of true

The "unsilence" action of the silence/hush command used `send_messages=True` when unsilencing a hushed channel. This had the side effect of also enabling send messages permissions for those with the Muted rule, as an explicit True permission apparently overwrites an explicit False permission, even if the latter was set for a higher top-role.

The solution is to revert back to the `Inherit` permission by assigning `None`. This is what we normally use when Developers are allowed to send messages to a channel.

Subject: Replace `in_channel` decorator by `in_whitelisted_context`

The `in_channel` decorator that served as a factory for `in_channel` checks was replaced by the broaded `in_whitelisted_context` decorator. This means that we can now whitelist commands using channel IDs, category IDs, and/or role IDs. The whitelists will be applied in an "OR" fashion, meaning that as soon as some part of the context happens to be whitelisted, the `predicate` check the decorator produces will return `True`.

To reflect that this is now a broader decorator that checks for a whitelisted *context* (as opposed to just whitelisted channels), the exception the predicate raises has been changed to `InWhitelistedContextCheckFailure` to reflect the broader scope of the decorator.

I've updated all the commands that used the previous version, `in_channel`, to use the replacement.

Subject: Add tests for `in_whitelisted_context` decorator

I have added tests for the new `in_whitelisted_context` decorator. They work by calling the decorator with different kwargs to generate a specific predicate callable. That callable is then called to assess if it comes to the right conclusion.

From b20bb7471b8d1d01f217f0620f8597bf1bae4456 Mon Sep 17 00:00:00 2001

Subject: Simplify `in_whitelisted_context` decorator API

The API of the `in_whitelisted_context` decorator was a bit clunky:

- The long parameter names frequently required multiline decorators

- Despite `#bot-commands` being the defacto default, it needed to be passed

- The name of the function, `in_whitelisted_context` is fairly long in itself

To shorten the call length of the decorator, the parameter names were shortened by dropping the `whitelisted_` prefix. This means that the parameter names are now just `channels`, `categories`, and `roles`. This already means that all current usages of the decorator are reduced to one line.

In addition, `#bot-commands` has now been made the default redirect channel for the decorator. This means that if no `redirect` was passed, users will be redirected to `bot-commands` to use the command. If needed, `None` (or any falsey value) can be passed to disable redirection. Passing another channel id will trigger that channel to be used as the redirection target instead of bot-commands.

Finally, the name of the decorator was shortened to `in_whitelist`, which already communicates what it is supposed to do.

Subject: Add DMChannel tests for in_whitelist decorator

The `in_whitelist` decorator should not fail when a decorated command was called in a DMChannel; it should simply conclude that the user is not allowed to use the command. I've added a test case that uses a DMChannel context with User, not Member, objects.

In addition, I've opted to display a test case description in the `subTest`: Simply printing the actual arguments and context is messy and does not actually show you the information you'd like. This description is enough to figure out which test is failing and what the gist of the test is.

Subject: Fix exception message assertions in converter tests

The `msg` arg is for displaying a message when the assertion fails. To
match against the exception's message, `assertRaisesRegex` must be used.
Since all of the messages are meant to be interpreted literally rather
than as regex, `re.escape` is used.

It also has the consequence of shortening the length of the invocation,

Subject: Fix autospec decorator when used with multiple attributes

The original approach of messing with the `attribute_name` didn't work
for reasons I won't discuss here (would require knowledge of patcher
internals). The new approach doesn't use patch.multiple but mimics it by
applying multiple patch decorators to the function. As a consequence,
this can no longer be used as a context manager.

Subject: Test `is_maybe_token` returns False for missing parts

In practice, this won't ever happen since the regex wouldn't match
strings with missing parts. However, the function does check it so may
as well test it. It's not necessarily bound to always use inputs from
the regex either I suppose.

Subject: Use `send_help` to invoke command help

After the refactoring of the help command, we need to use the built-in
method of calling the help command: `Context.send_help`. As an argument,
the qualified name (a string containing the full command path, including
parents) of the command can be passed.

Examples:

- await ctx.send_help("reminders edit")

This would send a help embed with information on `!reminders edit` to
the Context.

- await ctx.send_help(ctx.command.qualified_name)

This would extract the qualified name of the command, which is the full
command path, and send a help embed to Context.

- await ctx.send_help()

This will send the main "root" help embed to the Context.

Subject: Use `Command`-object for `send_help`

As @mathsman5133 pointed out, it's better to use the `Command`-instance
we typically already have in the current context than to rely on parsing
the qualified name again.

The invocation is now done as: `await ctx.send_help(ctx.command)`

Subject: Improve aiohttp context manager mocking in snekbox tests

I'm not sure how it even managed to work before. It was calling the
`post` coroutine (without specifying a URL) and then changing
`__aenter__`. Now, a separate mock is created for the context manager
and the `post` simply returns that mocked context manager.

Subject: Fix unawaited coro warning when instantiating Bot for MockBot's spec

The fix is to mock the loop and pass it to the Bot. It will then set
it as `self.loop` rather than trying to get an event loop from asyncio.
The `create_task` patch has been moved to this loop mock rather than
being done in MockBot to ensure that it applies to anything calling it
when instantiating the Bot.

Subject: Properly mock the redis pool in MockBot

Because some of the redis pool/connection methods return futures rather
than being coroutines, the redis pool had to be mocked using the
CustomMockMixin so it could take advantage of `additional_spec_asyncs`
to use AsyncMocks for these future-returning methods.

Subject: Finish .set and .get, and add tests.

The .set and .get will accept ints, floats, and strings. These will be
converted into "typestrings", which is basically just a simple format
that's been invented for this object.

For example, an int looks like `b"i|2423"`. Note how it is still stored
as a bytestring (like everything in Redis), but because of this prefix
we are able to coerce it into the type we want on the way out of the db.

Subject: DRY approach to typestring prefix resolution

Thanks to @kwzrd for this idea, basically we're making a constant with
the typestring prefixes and iterating that in all our converters.

These converter functions will also now raise TypeErrors if we try
to convert something that isn't in this constants list.

I've also added a new test that tests this functionality.

Subject: Remove redis session mock from MockBot

It's not feasible to mock it because all the commands return futures
rather than being coroutines, so they cannot automatically be turned
into AsyncMocks. Furthermore, no code should ever use the redis session
directly besides RedisCache. Since the tests for RedisCache already use
fakeredis, there's no use in trying to mock redis in MockBot.

Subject: Make .items return ItemsView instead of AsyncIter

There really was no compelling reason why this method should return an
AsyncIterator or than that `async for items in cache.items()` has nice
readability, but there were a few concerns. One is a concern about race
conditions raised by @SebastiaanZ, and @MarkKoz raised a concern that it
was misleading to have an AsyncIterator that only "pretended" to be
lazy.

To address these concerns, I've refactored it to return a regular
ItemsView instead.

I also improved the docstring, and fixed the relevant tests.

Subject: Add .increment and .decrement methods.

Sometimes, we just want to store a counter in the cache. In this case,
it is convenient to have a single method that will allow us to increment
or decrement this counter.

These methods allow you to decrement or increment floats and integers by
an specified amount. By default, it'll increment or decrement by 1.

Since this involves several API requests, we create an asyncio.Lock so
that we don't end up with race conditions.

Subject: Add support for Union type annotations for constants

Note that `Optional[x]` is just an alias for `Union[None, x]` so this
effectively supports `Optional` too.

This was especially troublesome because the redis password must be
unset/None in order to avoid authentication, but the test would complain
that `None` isn't a `str`. Setting to an empty string would pass the
test but then make redis authenticate and fail.

This is a simple validation that only check the type of the collection.
It does not validate the types inside the collection because that has
proven to be quite complex.

Subject: Fix valid token regex test

It was broken due to the addition of groups. Rather than returning the
full match, `findall` returns groups if any exist. The test was
comparing a tuple of groups to the token string, which was of course
failing. Now `fullmatch` is used cause it's simpler - just check for
`None` and don't worry about iterating matches to search.

Subject: Fix multiple match text for token regex

It has to account for the addition of groups. It's easiest to compare
the entire string so `finditer` is used to return re.Match objects;
the tuples of `findall` would be cumbersome. Also threw in a change
to use `assertCountEqual` cause the order doesn't really matter.

Subject: Add a test for RuntimeErrors.

This just tests that the various RuntimeErrors are reachable - that
includes the error about not having a bot instance, the one about not
being a class attribute, and the one about not having instantiated the
class.

This test addresses a concern raised by @MarkKoz in a review.

I've decided not to test that actual contents of these RuntimeErrors,
because I believe that sort of testing is a bit too brittle. It
shouldn't break a test just to change the content of an error string.

Subject: Refactor the in_whitelist deco to a check.

We're moving the actual predicate into the `utils.checks` folder, just
like we're doing with most of the other decorators. This is to allow us
the flexibility to use it as a pure check, not only as a decorator.

This commit doesn't actually change any functionality, just moves it
around.

Subject: Refactor .increment and add lock test.

The way we were doing the asyncio.Lock() stuff for increment was
slightly problematic. @aeros has adviced us that it's better to just
initialize the lock as None in __init__, and then initialize it inside
the first coroutine that uses it instead. This ensures that the correct
loop gets attached to the lock, so we don't end up getting errors like
this one:

RuntimeError: got Future <Future pending> attached to a different loop

This happens because the lock and the actual calling coroutines aren't
on the same loop. When creating a new test, test_increment_lock, we
discovered that we needed a small refactor here and also in the test
class to make this new test pass.

So, now we're creating a DummyCog for every test method, and this will
ensure the loop streams never cross. Cause we all know we must never
cross the streams.

Subject: Floats are no longer permitted as RedisCache keys.

Also added a test for this.

This is the DRYest approach I could find. It's a little ugly, but I
think it's probably good enough.

From f66a63501fe1ef8fb5390dfbe42ae9f95ea2bc28 Mon Sep 17 00:00:00 2001
From: Leon Sandøy <leon.sandoy@conmodo.com>
Date: Thu, 28 May 2020 01:29:34 +0200
Subject: Add custom exceptions for each error state.

The bot can get into trouble in three distinct ways:
- It has no Bot instance
- It has no namespace
- It has no parent instance.

These happen only if you're using it wrong. To make the test more
precise, and to add a little bit more readability (RuntimeError could be
anything!), we'll introduce some custom exceptions for these three
states.

This addresses a review comment by @aeros.

Subject: Adjust find_token_in_message tests for the recent cog changes

It now supports the changes that switched to finditer, added match
groups, and added the Token NamedTuple. It also accounts for the
is_maybe_token function being removed.

For the sake of simplicity, call assertions on is_valid_user_id and
is_valid_timestamp were not made.

Subject: Incidents tests: set up base class for `Incidents`

For cleanliness, I've decided to make a separate class for each method.
Since most tests will want to have an `Incident` instance ready, they
can inherit the `setUp` from `TestIncidents`, which does not make any
assertions on its own.

Subject: Incidents tests: write tests for `process_event`

This also breaks the helpers import statement into a vertical list,
as the amount of imports has grown too much. I still believe that
this is a preferred alternative to accessing the helpers via module
namespace, as we use them a lot, and the added visual noise would
be annoying to read - their names are already descriptive enough.

Subject: Incidents: try-except Signal creation

Suggested by Mark during review. This follows the "ask for forgiveness
rather than permission" paradigm, ends up being less code to read, and
may be seen as more logical / safer.

The `ALLOWED_EMOJI` set was renamed to `ALL_SIGNALS` as this now better
communicates the set's purpose.

Tests adjusted as appropriate.

Subject: Incidents: implement `make_username` helper

The justification is to incorporate the `actioned_by` name into the
username in some way, and so the logical thing to do is to abstract
this process into a helper so that it can easily be adjusted in the
future. For now, I've chosen to separate the names by a pipe.

Discord webhook username cannot exceed 80 characters in length, and
so we cap it at this length by default. This is seen as more of an
edge-case, but it should be accounted for, as we're not joining two
names. The `max_length` param is configurable primarily for testing
purposes, it probably should never be passed explicitly.

This commit also provides two tests for the function.

Subject: Incidents: revert latest 2 commits

Decision was made to use embeds to archive incidents instead of
webhooking the raw message. As such, we're reverting the branch
to a state from which the adjustments will be easier to make.

Reverted commits:
* a8d179d9b04f54b20c5e870bcfa85c78c42c8dca
* 6fa8caed037b247a7c194f58a4635de7dae21fd2

This applies the previously defined `make_embed` function.

As the `archive` function is now simpler, I decided to reduce the
amount of whitespace ~ it's a lot more compact now.

Tests are adjusted as appropriate.

Subject: Incidents: archive incident attachments

There is no handling of file types as explained in the `archive`
docstring. Testing indicates that relaying incidents with e.g. a text
file attachment is simply a noop in the Discord GUI.

If there is at least one attachment, we always only relay the one
at index 0, as it is believed the user-sent messages can only contain
one attachment at maximum.

This also adds an extra test asserting the behaviour when an incident
with an attachment is archived. The existing test for `archive` is
adjusted to assume no attachments.

Joe helped me conceive & test this.

+        cannot be displayed (e.g. a text file), it's invisible in the embed, with no error.

         not all information was relayed, return False. This signals that the original

Subject: Fix DuckPond tests now that send_webhook is gone.

to be a method of the DuckPond cog, other tests simply were no longer
applicable, and have been removed.

Subject: Incidents: link `proxy_url` if attachment fails to download

Suggested by Mark during review. If the download fails, we fallback
on showing an informative message, which will link the attachment
cdn link.

The attachment-handling logic was moved from the `archive` coroutine
into `make_embed`, which now also returns the file, if available.
In the end, this appears to be the smoothest approach.

called if an exception is raised in setUp.

Subject: Restructure bot.filter_list_cache.

This is an optimization designed to eliminate all the list
comprehensions we were doing inside antimalware and filtering. The cache
is now structured so that the content is the key and the metadata is the
value.

From b224d46d68699ece3382cd333df7ede9e9a62e02 Mon Sep 17 00:00:00 2001
From: MarkKoz <KozlovMark@gmail.com>
Date: Wed, 12 Aug 2020 14:31:56 -0700
Subject: Restructure tests and fix broken tests

The cog tests structure should mirror the structure of the cogs folder.
Fix some import/patch paths which broke due to the restructure.

Subject: Rename "cogs" directory to "exts"

The directory contains modules, which are extensions. It only indirectly
contains cogs through the extensions. Therefore, a technically more
accurate name is "extensions", or "exts" when abbreviated. Furthermore,
"exts" is consistent with SeasonalBot.

Subject: Tests: optionally prevent autospec helper from passing mocks

Not everything that's decorated needs the mocks that are patched. Being
required to add the args to the test function anyway is annoying. It's
especially bad if trying to decorate an entire test suite, as every
test would need the args.

Move the definition to a separate module to keep things cleaner.

Subject: Silence tests: fix mock for _init_task

An `AsyncMock` fails because it returns a coroutine which may only be
awaited once. However, an `asyncio.Future` is perfect because it is
easy to create and can be awaited repeatedly, just like the actual
`asyncio.Task` that is being mocked.

Subject: Silence tests: add a test for default overwrites on cache miss

Use a False for `add_reactions` in the mock overwrite rather than None
to be sure the default (also None) is actually set for it.

Fix channels set by `_init_cog` not being mocked properly.

The module is imported anyway to keep imports short and clean. Using it
in patch targets is shorter and allows for the two imports from the
module to be removed.

Subject: Silence tests: remove _reschedule patch for cog tests

They don't do anything because they patch the class rather than the
instance. It's too late for patching the instance to work since the
`setUp` fixture, which instantiates the cog, executes before the patches
do. Patching `setUp` would work (and its done in the other test cases),
but some tests in this case will need the unpatched function too.
Patching it doesn't serve much benefit to most tests anyway, so it's
not worth the effort trying to make them work where they aren't needed.

Subject: Sync: remove confirmation

The confirmation was intended to be a safe guard against cache issues
that would cause a huge number of roles/users to deleted after syncing.
With `wait_until_guild_available`, such cache issue shouldn't arise.
Therefore, this feature is obsolete.

Resolve #1075

Subject: Use async-rediscache package for our redis caches

I've migrated our redis caches over to the async-rediscache package that
we've recently released (https://git.pydis.com/async-rediscache). The
main functionality remains the same, although the package handles some
things, like getting the active session, differently internally.

The main changes you'll note for our bot are:

- We create a RedisSession instance and ensure that it connects before
  we even create a Bot instance in `__main__.py`.

- We are now actually using a connection pool instead of a single
  connection.

- Our Bot subclass now has a new required kwarg: `redis_session`.

- Bool values are now properly converted to and from typestrings.

In addition, I've made sure that our MockBot passes a MagicMock for the
new `redis_session` kwarg when creating a Bot instance for the spec_set.

From de4a8d960f9f845467efb470e17a0e9685df1bdc Mon Sep 17 00:00:00 2001
From: Sebastiaan Zeeff <sebastiaan.zeeff@gmail.com>

Subject: Remove vestigial RedisCache class definition

As we're now using the `async-rediscache` package, it's no longer
necessary to keep the `RedisCache` defined in `bot.utils.redis_cache`
around.

I've removed the file containing it and the tests written for it.

-    A simplified interface for a Redis connection.
-
-    We implement several convenient methods that are fairly similar to have a dict
-    behaves, and should be familiar to Python users. The biggest difference is that
-    all the public methods in this class are coroutines, and must be awaited.
-
-    Because of limitations in Redis, this cache will only accept strings and integers for keys,
-    and strings, integers, floats and booleans for values.
-
-    Please note that this class MUST be created as a class attribute, and that that class
-    must also contain an attribute with an instance of our Bot. See `__get__` and `__set_name__`
-    for more information about how this works.
-

-
-    class SomeCog(Cog):
-        # To initialize a valid RedisCache, just add it as a class attribute here.
-        # Do not add it to the __init__ method or anywhere else, it MUST be a class
-        # attribute. Do not pass any parameters.
-        cache = RedisCache()

-

-            # we access self.cache through an _instance_ of this class.
-            #
-            # For example, attempting to use SomeCog.cache will _not_ work,
-            # you _must_ instantiate the class first and use that instance.
-            #
-            # Now we can store some stuff in the cache just by doing this.
-            # This data will persist through restarts!

Subject: Remove unit tests for duck pond

I've removed the unit tests for duckpond in concordance with the new
policy for writing unit tests for the bot The tests were unnecessarily
complicated, difficult to maintain, and slowed development.

Subject: Silence: remove _mod_log_channel attribute

It's only used as an argument to `SilenceNotifier`, so it doesn't need
to be an instance attribute.

Subject: Silence: require only 1 permission to be False for a manual unsilence

Previously, both sending messages and adding reactions had to be false
in order for the manual unsilence failure message to be sent. Because
staff may only set one of these manually, the message should be sent
if at least one of the permissions is set.
