Tags that the WML parser rejects shouldn't be possible to create with Lua,
either. This ensures that a UMC author can't accidentally, or deliberately,
inject such tags into the game state and make saving the game impossible.
Fixes#2375.
Only happened if the player used the buttons in the addon list: the buttons
in the right panel worked fine. The problem was that the addon list caught
the addons_client::user_exit exception separately and didn't rethrow it
when necessary, unlike the addon manager itself.
I decided to simply throw a different exception instead.
Fixes#2312. Turns out constructing a list of matching handlers breaks some undocumented
behavior, namely events being executed in the order they're added (usually the order in
which they appear in the WML). It also broke certain variable substitution by moving variable
interpolation wholly before any event execution, as opposed to between each event.
This commit implements an even simpler method: simply iterating through every registered
handler in order, checking for a name match on each one, and if it passes, immediately
executing the provided function. Cleanup will only occur once the toplevel call to
execute_on_events is completed.
This commit also removes the immediately cleanup upon removing a handler. This should
ensure (I didn't test explicitly, but from other incidental issues I'm sure this is the
case) the size of the main vector doesn't change during iteration.
I also changed the pre-add standardization code to only affect event names without variables.
Variable names are standardized later after variable substitution.
Empty action chains are not allowed, attempting to partially undo an empty
chain causes a fatal error.
This commit fixes some of the breakage reported in #2306, but not all.
I chose 2560x1440 as the size over 1920x1080 simply because when I tried both sizes at compression levels that produced a similar quality result, the difference in filesize was negligible.
The handshake value is 42. The server sends this on startup in response to a zero-length document.
Yes, that means the server replies with The Answer to The Ultimate Question of Life, the Universe, and Everything. It is unspecified whether the client properly interprets The Answer.
The bans were not being immediately written to the file when created or removed.
Note that the file is overwritten directly rather than saved to a temporary and moved into place. This creates a race condition: a crash while writing corrupts the file.
When a banned or connection-limited client attempts to log in, it hangs.
This is because the client does not understand that the server did not finish the handshake. This moves the check to a point just after the handshake has completed (when the server would normally ask for a version number). The client never checked for errors, so added a check.
As players who haven't figured out certain strategies might have too much
trouble beating the third repetition. Also waiting until the fourth
repetition may be too long and have players question what's going on.
Bug was that a troll on 4,21 could move through the avoid area to attack
player at 11,22 which is a likely occurrence. Expanding the avoid area
further seems inappropriate as troll avoidance is more likely to be noticed.
New implementation ensures only player will trigger the wose, maintains
proper look to the player, no longer interferes with trolls attacking, and
simplifies code.
