6.6.6

Changes between 6.6.5 and 6.6.6

This slightly cursed version of Sopel is brought to you by the following happy
coincidences. When this release cycle began:

• 6.6.6 was the next patch version number
• Tax Day (in the U.S.) was just a few weeks off — the perfect release date

As it happens, the v6.6.6 GitHub milestone ended up with 13 closed
issues/PRs in total. We definitely didn't try to plan any of this. Promise.

Module changes

• Potential denial-of-service via repeated long output in the .py and .calc
  commands was mitigated [#1552]
• admin module's .set command no longer throws an exception if missing
  arguments [#1520]
• Fixed admin module's .mode command sending invalid raw line [#1549]
• Tweaked output-formatting code in the meetbot & reddit modules [#1516]
  • The most visible effect of this is that moderators' names will now appear
    green in reddit's output, like on the site, instead of the old brown/purple
• Updated example/test output for .ip command [#1523]

Core changes

• Flood protection delay is now capped at 2 seconds [#1552]
  • The flood delay penalty is calculated using the message length before
    truncation. Very long command output could thus "hang" the bot for many
    minutes at a time, meaning some modules could be used to DoS the bot.
  • Sopel 7 will add configuration for flood protection and perhaps reorganize
    the logic to reduce silly bugs like this. (See: #1518, #1559)
• Fixed a few cases where keyboard interrupt (Control + C) wasn't handled
  correctly [#1534, #1558]
• Fixed invalid MODE command sent during connection phase [#1544]

API changes

• Fixed a regression in testing modules by running them directly [#1529]
• Fixed that bot output methods (say, reply, etc.) would cause errors
  during tests if passed certain keyword arguments [#1538]
