Cleanup Math
Math module clearly doesn't conform to the style guidelines. Does it
make sense to go and clean it entirely or should we do it for the ones
we use, when we use it?

An entire beer for but a two-epsilon change in my vote? That's a pretty

BeerPerVote ratio, I better grab that before the market sees how inflated it

We've been through it before: making massive formatting
changes can:
a) break patches. Biggest reason, not the case here.
But the point is that it sets (grr, continues) a precedent:
what if someone was on vacation and not reading emails,
and we all said, "I'm not touching that module, go ahead
and reformat", and because they were away for the 3-day
period in which the discussion happened, their patches
are totally trashed. And don't say this is a "one time
thing", because if we decide to change some rule later,
some of the current code may be "in violation" of the
new rule, or if we adopt another project, the first step
is always: see if it works first, then worry about
formatting later.
b) screw up svn modification history and IDE support
of showing diffs, which trying to track down who changed
something, it basically suddenly becomes "Robin/Sean
did!" as the answer to every file.
And frankly, I just hate having people (even not-me people!)
running around just autoformatting stuff for the sake of it.
It makes it the opposite of "easy and fun" for me.
But as I said, I really don't feel like giving this a "-1"
followed by a big backing-up-of-all-of-my-points as to
"why", so I'll stick with the tried-and-true
passive-aggressive Apache "-0" as my vote on this,
and leave it at that, not really wanting to discuss it
too much further.

I found, as you will recall, a certain number of surprises in the
collections subset.
You might say that we collectively took out a loan at the credibility
bank by incorporating this stuff, deprecations or no, and might be
well-advised to try to find time to write tests and repair problems
(or remove dubious stuff altogether).

+1 from me as well.
The approach also clearly separates stable, but in future versions no
longer supported code (deprecated) from experimental, but in future
versions better supported code. Should make it easier for the user to
decide which pieces of Mahout to use.

I think that this is fine. Essentially this is a more fine grained approach
to what we have been doing with deprecated.
The real virtue of this is that it promotes visibility of the known good
stuff and thus exerts a good social pressure.
I do think that we need to push for code quality as quickly as is
reasonable, but definitely at the patch level, we should encourage
contributors to post early versions.

Check this out. This looks like a clean way to solve this issue in Mahout as
well. If we annotate each package as public stable, private stable, public
unstable, and so on and so forth, and keep only the stable ones in the
javadoc, Users will find the documentations a lot more readable. Plus
developers can keep adding experimental stuff with bad style as long as it
is not marked visible. We can keep separate quality levels for each
visibility. Mahout will always attract experimental code, so instead of
driving it away and waiting for the quality to go up before committing, we
can annotate it at the least quality level and when it improves, we can
change the annotation along with the improvements.
I can help creating a patch like this, if everyone is onboard

I wasn't here when you all picked up Colt, but I wonder if we want to
pick a middle ground between carrying around @deprecated code that no
one feels like testing and deleting it altogether. Work went into IP
clearance and all that. I'd identifying the things that look furthest

I'd say this:
I'll go for it if you can go through all of JIRA and assure me there are little to no issues open against it that need to be fixed. It's not even necessarily the active ones. Either that or promise to update/fix them once the reformat is done.
I still, however, think it is pointless unless we have a process in place that automatically reformats every commit, as it is bound to be one of those annoying little things that prevents people from contributing b/c they have to have the formatting just right in order to contribute.

This is terrible! I went to sleep on this side of the world and people on
the other side have already bartered votes for beer. For being the reason of
the getting a vote call going by mistake, I object this
reflexive behavior and instead propose for a transitive one.
If we are not going to touch (use, format, delete or make api compatible)
many of these deprecated code. Instead, how about marking stuff as
@deprecated. So that it is clear to new developers reading the code that
those module are not to be examined.

"OK"? It's always ok to *fix* it, I'm just saying it's not terribly helpful
to
"fix" the style errors without fixing the underlying code, and I'm saying
it's
not ok to just remove it because we haven't gotten around to fixing it up

It's better than the "professional" code I've seen in many companies whose
code I've read or had to use. It has rough parts which are untended, just
like
codebases, except there are actually far fewer of these in our codebase, and
in fact ours has the benefit of that code not actually being used right now,
unlike corporate environments where the code gets embedded in some system
which is in use and can *never* be removed, leaving its bugs as little
time-bombs.

hearing objections to even style changes.
What is the game plan you envision then? When is it OK to touch any of this?
Honestly the code quality in this project is not yet professional. Its much
better than a lot of projects. But I participate to make code that is better
than anything a professional organization is capable of.

I agree which is why I am not excited by the task of scrubbing the details
but dont mind if someone else does at all. I already had my way with core
and examples which are more interesting. They're now pretty in line with
checkstyle rules.
Better still in math would be to chuck out the pieces we haven't found a use

The math (Colt) stuff is a special case, and in fact, is one which will lull

I am sympathetic to Jake's point of view in general, but I think that the
math stuff is a bit of a special case.
I have had two patches recently that could have been affected. One was
adding test cases and correcting some of the distribution code (a kind angel
committed that already). Another is beginning of work on stochastic
matrices.
I am happy to rebase any work that I have pending.

Re: Cleanup Math
Posted by Sean Owen <sr...@gmail.com>.
Agree, which is why I'd rather just nail this once rather than dribble it in.
It's reasonable to say you just don't think the formatting and style
stuff matters, but I find it does, indirectly, from a "broken windows
policy" perspective. If your code *looks* a bit uneven and
inconsistent, people have less compunction about checking in more
uneven code (since it already is) and have a general sense that it's
alright to check in stuff that's maybe not as completely baked as
would be ideal -- since it looks like anything goes.
And I don't think we're spending too *much* time thinking about design
and such. So is it so painful to let someone else touch up, on
everyone's behalf, the code base? we really should have been checking
in better code from the get-go.
Turned around... I also don't see the argument against cleaning this
up. Do you have a patch? fine, we can wait until you're ready check
in. This is a real no-skin-off-your-nose change so, ?

Erggg..... once I again I will state that I strongly prefer Grant's
approach.
Do findbugs and formatting "errors" actually cause people physical pain?
Why does this keep coming up?
-jake
ps. no I doubt anyone is working on those files. Doesn't change my
opinion of massive formatting checkins.

Re: Cleanup Math
Posted by Robin Anil <ro...@gmail.com>.
Correct me If I am wrong, I believe there are no conflicts for many of the
following top violators (except the matrix/linalg which Jake may have some
changes). So there shouldn't be a problem with formatting these. Is anyone
working on any of these classes?

Re: Cleanup Math
Posted by Sean Owen <sr...@gmail.com>.
I'd prefer to have a quick big-bang change, if indeed there aren't any
outstanding patches.
(If only to retroactively justify the fact that I just did the same to
core and examples.)
I think this is something we should focus on fixing up now, then going
forward we can actually pay attention to checkstyle warnings.

There are arguments in both directions. In my view, the ideal is:
1) declare a target date.
2) everyone clears the deck of patches.
3) Reformat
Grant's proposal, which goes
1) have a reason to modify some particular bit
2) check in patch
3) check in reformat before someone else starts a patch
is not bad, either.
