* All logging is also going into the log file (always), debug output is
mostly/only going into the log file. File logging uses an asynchronously
processed queue now (!).
* Specify an existing directory (e.g. logs) and log files will named
after date + sequence number, changing with every reloading of the
configuration.
* Console and ingame logging remain within the primary thread.
* No extra configurability for customization, yet.
* Not all places have been cleaned up, concerning log levels. target
streams and package naming.
* Work in progress.
Hinting at further changes to unify permission access and caching. Later
permission caching can also be done for moving checks, though checking
for the current thread may be exchanged in favor of config flags.
Generic configuration will allow to set individual timeouts for checks,
check groups and default. There could also be change policies like
"world change only", possibly listening to permission updates, if
feasible.
CheckData / AsyncCheckData are not as simple to unify, if we want to
keep the footprint as low as possible there. There could even be more
implementations to match different policies.
* Always log location of logout if debug is set.
* Also check inconsistent logout if manahattan distance is > 0.
* Only perform "passable check" only if enabled and not dead/sleeping.
* Try to actually set-back.
Since other fixes migth be in focus, some changes are commited
merged/commented out:
* Prepare AxisVelocity to carry positive and negative values.
* Prepare MovingData to use vertical AxisVelocity. Rename hVel.
* Prepare CreativeFly (...), do not count velocity for height limit.
(Most preparations were unfinished, just hinting at the direction.)
AxisVelocity will later represent per-axis velocity accounting for both
directions along an axis.
There have been no changes to the functionality, so it still only
accounts for positive values.
Previously the max. bounds hitting the block edge would not be
considered as colliding, this can now be controlled with a flag.
If the flag is set, you will collide at offsets of 1.0 for either
coordinate (not if the offset is < 1.0).
* Better coverage of block-transitions: One step per axis, dT can be 0.
* Cover one step always, also if no distance is covered.
There might be more false positives, due to newly intoduced bugs, or due
to not all block-transitions being checked (a x + z transition will have
two variations to test extra to the ordinary diagonal path, but only one
is checked).
