I use Debian (testing), Postgres 9.4,
and Web2py 2.14.6 (with current trunk is problem the same)
I use such command (assigned to an alias) for long time to start my
application
python web2py.py -K codex2020 -X $@
Today I received strange behaviour, errors like
web2py.scheduler TICKER: error assigning tasks
or such something (with no effect if I have deleted scheduler_* tables and
their databases/ metadata earlier)
starting scheduler for "codex2020"...
Currently running 1 scheduler processes

HINT: You will need to rewrite or cast the expression.
Then I decided then if I run without $@, all will start well:
python web2py.py -K codex2020 -X
After testing of everything I went back to:
python web2py.py -K codex2020 -X $@
or
python web2py.py -K codex2020 -X "$@"
and I have now no more the previous problem. All works well.
Has somebody any idea about the reason of problems
and can you explain me the difference between $@ and "$@". Which one is
more safe to use? Is there a difference?
Thanks...
