To be honest, I the Sage review process seems cumbersome to me.
Following the instructions (
http://www.sagemath.org/doc/developer/
walk_through.html) I cloned a sub directory to hold my newly
implemented gsl probability distributions (binomial and negative
binomial to name only two). These work fine with my system.
Next, I wanted to contribute these new distributions. As there already
exists a patch for the F distribution (
http://trac.sagemath.org/
sage_trac/attachment/ticket/9080/trac_9080-rebased.patch), I wanted to
review this first, but following the instructions for 'Reviewing a
patch' [hg_sage.apply("<full-path-and-filename.patch>") etc.] did not
change anything perceptible. The F distribution still is not
available, and hg_sage.log() produces such a long list that even after
several minutes I became tired of scrolling down. When I check the
files that should be affected by the patch, nothing has changed.
