15.2: Reporting Bugs
Bug reports help make Gri more reliable and useful for all users, so
please report any bugs you find. The scheme will be familiar to you, if
you've participated in open-source work before.
Visit the bug-tracking part of the Source Forge Gri development site, at
to see whether your bug has already been reported. You may find that it
has been reported and fixed already in a new version, in which case you
should archive your existing Gri version and upgrade. If the bug has
been reported and not fixed, then you may still wish to add a
supplemental bug report, so the author knows that this bug is of concern
to you as well as the others. (Plus, reporting it this way ensures that
you'll receive an email when the bug is fixed.)
Debugging is made easier if the problem is reduced in scope.
Therefore, please reduce your application and your data to the
simplest case that produces the error.
If you know how, please try to find the bug yourself. After all, Gri
is open-source for a reason! The procedure is described in the next
section (see Killing Bugs).
