Hi,
Attached is a patch to eliminate a FIXME in qp.m. This adds an
extra arg to qp() to specify the maximum number of iterations.
The old hard-coded value of 200 iterations is sometimes insufficient
for convergence.
I originally posted this 3 months ago, but perhaps sent it to the
wrong list. I've update the diff to the current repository version.
I haven't contributed before, so please let me know if there's
something else I should do.
Thanks,
Josh
<qp.diff>
Josh,
I'm unfamiliar with qp(). Is it possible to add some tests that
validate this change?
Ben
I attached a diff of a followon changeset that adds a few tests to
qp.m to exercise the maxit argument.
I actually don't understand qp.m internals so the examples are
pretty contrived.
Also, I have mercurial 1.0.1 and I couldn't figure out how to
generate a single 'export' style patch that included both changesets.
Josh
I don't know if it is possible to export a patch that includes two
changesets. What I tend to do is create a changeset for each, and
import them into a virgin mercurial archive and then produce a
changeset (I hope that makes sense). The only caveat is that the 2nd
Changelog entry may not apply, so I edit the Changelog manually and
then generate a combined changeset.
I expect someone with a better understanding of mercurial will
educate us sometime tomorrow :-)
Regarding the Changelog, you should add the change to the Changelog
file in the scripts directory. Thus the changeset should include
something like what is below ...

Yeah, it'd be great if 'export' somehow took multiple changesets.
In the meantime, are the simple tests I added to qp.m what you were
looking for?
I just made sure the the maxit did something useful and didn't break
the old call signature.
