Log Message:
Activated runtime switches for Mserver and mclient to enable the algebra
back-end
with a default compilation of pathfinder (i.e., with the "milprint_summer"
back-end
the compile-time default).
Mtest.py & mclient provide a "-G"/"--algebra" to use the algebra back-end
instead of the "milprint_summer" back-end (compile-time default).
In an interactive `mclient -lxquery` sessions, commands "\G" & "\g"
are available to enable & disable the algebra back-end, respectively.
(Mserver maintains the state per client session, i.e., after a "\G"
on the mclient console, all subsequent XQueries in the same session
will be compiled with the algebra back-end, until a "\g" is given.)
Starting the server with
`Mserver --dbinit="module(pathfinder);" --set xquery_backend=algebra`
activates the algebra back-end as default for all client sessions.
In that case, only the "\g" command in an interactive `mclient -lxquery`
session allows the user to switch to the "milprint_summer" back-end.
NOTE:
(For the time being?) Neither Mtest.py nor mclient provide a command line switch
to disable the algebra back-end; hence, when pathfinder is compiled with the
algebra back-end as default (`configure --with-default-backend=algebra`),
there is no way to (conveniently) switch to using the "milprint_summer"
back-end,
except from starting the server via
`Mserver --dbinit="module(pathfinder);" --set xquery_backend=milprint_summer`,
running `pf -M` or using the "\g" command in an interactive `mclient -lx`
session.
