Hello, I'm trying to help on Cassandra

[Jérémy SEVELLEC]

Hello everyone,

Let me present me : I'm Jeremy. I'm French and author of cassandra-unit. I
trying to help on Cassandra.


I'm looking at the
CASSANDRA-2961
 which is about gossip and dead states removal. I'm trying to understand how
unit tests are done about gossip. For now, I've just find some unit test
into org.apache.cassandra.gms but there is not a lot of things.

how did you usually make your gossip tests?

Regards,

I definitely think this is the right move.

Either would be good, but I have a preference for GitHub (easier workflow).

Unfortunately, Gossip falls into the category of "usually we have to
test it manually."

You might be able to do something using ccm [1] and the recently added
JMX hooks for Gossip [2], as in this script: [3].  But again, if you
decide to test manually you won't be alone. :)

Looks like it.  The opinions on irc were positive, too.

No strong feelings here.

ok it's a bit surprising but it is also true that doing this kind of gossip
test with unit tests should not be obvious...

CCM is indeed very useful and works well. I wanted to be sure not to
miss anything with unit test :-)

Generally I prefer Github too, but the branding is better on Apache
Extras.  I almost want to say that Google's issue tracker is better
too, but maybe not.

I guess if we're fair about it, the ability to choose between Git,
Mercurial, and Subversion is probably a "feature" as well. :)

I was planning to, (later this morning or early afternoon), but if
you'd rather take it,  you're welcome to it. :)

Also, welcome back.

I agree that apache extras makes better sense sense it's Branded (tm) and
has git.

I wouldn't want to mess up you carefully planned planning :) I'm glad
to leave you this
one as I've not look too carefully of what went in it.
