I finally solved that issue:
Now all events occuring at watched pathes are checked whether they refer
to a temporary file. If this is true, they are ignored.
A temporary file is defined as:
- - either ends or starts with "#"
- - is a hidden file (starts with ".")
- - is a backup file (ends with "~" or ".bkp")
- - consits only of digits (yes ViM does such crazy stuff)
And to reduce the reload-calls even more: All events that trigger a
reload in a specific time frame (at the moment: 2 seconds) are taken as

this is still a todo.

Catapult now seems quite reliable. Some functionality still has to be
- - different API versions (*)
- - central library (for use flags, central administration etc) (*)
- - allow the server to be stopped from outside. this is esp. important
when installing a new version - the old version running should then stop
and the new one should start ;)
- - extended API ... if there are no more API requests I will take the API
as version 0 and all future extensions will be API v1.
(*): not a blocker: so if this cannot be done in time, it can be delayed
@araujo: How are the chances that catapult can get into tree in some
weeks? - Would you (proxy-)maintain it?
If yes, the next portato version (which will come in like 3 to 4 weeks I
hope) would only use catapult as backend (except of course another major
This would allow me, to focus on maintaining the catapult backend and
not having to deal with two things. (For example the update_world needs
