* [commands] Redesign extension exception flow.Rapptz2019-03-192-21/+115
| | | | | | | | | | | | | | | | Instead of raising a whole variety of exceptions, they are now wrapped into ExtensionError derived classes. * ExtensionAlreadyLoaded * Raised when an extension is already loaded in Bot.load_extension * ExtensionNotLoaded * Raised when an extension is not loaded, e.g. Bot.unload_extension * NoEntryPointError * Raised when an extension does not have a `setup` function. * ExtensionFailed * Raised when an extension's `setup` function fails. * ExtensionNotFound * Raised when an extension's module import fails.
* [commands] Add Bot.reload_extension for atomic loading.Rapptz2019-03-191-43/+106

* [commands] Walk through MRO for Cog derived classes.Rapptz2019-03-171-23/+37
| | | | | | | This should support cog subclasses in a relatively consistent way in terms of expectations. Hopefully nothing is broken. Fixes #1950
* [commands] Make Bot.cogs and Bot.extensions read-only mappings.Rapptz2019-03-171-12/+23
| | | | | This also has the side effect of effectively documenting them for public use.
* Fix pagination of huge command help messages (> ~2,000 chars)slice2019-03-161-2/+12
| | | | | | | | | | Previously, calls to add_line in add_command_formatting of default help commands would fail if the command's help message would overflow the current page. This would also result in silent failure as the RuntimeError raised from add_line is never caught. This patch adds behavior that adds lines individually should it raise, which guarantees safe pagination as long as every line is smaller than the maximum page size, which is highly unlikely.

* [commands] Separate view parsing errors from BadArgument.Rapptz2019-03-122-6/+60
| | | | | | | | This causes them to be raised from a new exception named ArgumentParsingError with 3 children for ease with i18n. This is technically a breaking change since it no longer derives from BadArgument, though catching UserInputError will prevent this change from affecting the user.

* [commands] Update stale parent references in subcommands.Rapptz2019-02-231-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug was kind of a long one to figure out, as per #1918 documents the issue had to do with subcommands but the actual adventure in finding this one was a long one. The first problem was that Command.cog was for some reason None, which indicated that a copy was happening somewhere along the way. After some fiddling I discovered that due to the copies of `Cog.__cog_commands__` the groups pointed to out-dated versions that got overriden by the new copies. The first attempt at fixing this was straightforward -- just remove the subcommand from the parent and replace it with the newer reference that we just received. However, this ended up not working due to a strange mystery where the subcommand being invoked was neither the original copy nor the new copy residing in `Cog.__cog_commands__`. Some more investigation later pointed out to me that a copy occurs during the `Group.copy` stage which calls `Command.copy` for all its subcommands. After spotting this out I had realised where the discrepancy comes from. As it turns out, the subcommand copy that was being invoked was actually a stale one created from `Group.copy`. The question remained, how come that one was being called? The problem stemmed from the fact that when the subcommand was copied, the parent reference pointed to the old parent. Since the old parent was the one that was getting the new reference, it went practically untouched. This is because the calling code fetches the child from the parent and the old parent is nowhere in the call chain. To fix this issue we needed to update the parent reference, and in order to do that a temporary lookup table is required pointing to the latest copies that we have made. Thus ends a 3.5 hour bug hunting adventure.
