Re: [Duplicity-talk] Support for AWS S3 "Infrequent Access" Storage Option

[John]

Kenneth & Aaron, 

Thanks for your replies!

For the patch, manpage has been amended, blueprint filed: https://blueprints.launchpad.net/duplicity/+spec/aws-s3-std-ia-class, and merge proposed: https://code.launchpad.net/~mnjul/duplicity/s3-infreq-access/+merge/274037

For testing, I have tested my branch against both python2.6 and 2.7. Most are good except for linting & pep8 errors that don't involve my modifications. I have opened up another thread ("Unit test errors -- what to do?") for it.

I hope everything sounds good so far. Please definitely tell me if there's anything else I can do on my side for the patch.

My best,

John

Hi John,

Great to have another person keen to contribute!

To add to Kenneth's email, there isn't too much written guidance, but please make sure you've read README-REPO:
http://bazaar.launchpad.net/~duplicity-team/duplicity/0.7-series/view/head:/README-REPO
and please make sure all tests pass before you propose a merge.

Kind regards,

Aaron

Yes, file a bug report / enhancement request and tie the merge request to it.

Just propose the merge and it should happen fairly quickly.  I've already looked at the code (fairly simple) and have only one request.  Please update the man page as well so others will know about the additional option.

Thanks Edgar! The new value turned out to be STANDARD_IA as documented in AWS [1].

I have made a small patch for duplicity commandline to accept the new storage class: http://bazaar.launchpad.net/~mnjul/duplicity/s3-infreq-access/revision/1131 and I'd like to contribute back into duplicity if that's at all possible.

As such, could anyone point me to guidelines/rules for contributing back to the official repository?

I'm looking for project-specific rules like:

1. If I should file a bug first and link my branch/commit message to that bug, and/or

2. If I should just propose a merge through launchpad, and if so, who shall I ask for review? Is there a predefined set of review types?

Much appreciated!

- John

i guess that they introduced a new storage class value. see how it is done for rrs
