Greetings Jose,

Thanks a million for this submission! This is right on time with the U1 service closure, and a great addition to the charm store since its such a major version upgrade.

I'm going to ask that you document the behavior when deploying, and migrating an existing deployment to scale out usage with MySQL, that the file structure in the database is not preserved so users know its single host or multi-host from the git go until a patch is released to fix this behavior.

Otherwise, everything else is great. It passes all my tests.

Thanks for this submission! once the readme update is applied I'll merge this into the charmstore.

Added note on README

All ready!

Hello again Jose,

Prior to merging I wrote this review while I was still actively reviewing a few fringe cases I had not thought of. I did not upgrade from a 4.x to 6.x release, which is an important factor. Presently this will break owncloud for users that have existing deployments.

The upgrade-charm hook has some syntax errors on the find command, -exec blocks need to be terminated with an escaped semicolon like so:

 # Excise old installation data
 find /var/www -mindepth 2 -maxdepth 2 -type d -name 'data'\
  -exec mv {} /var/tmp/ \;

and it should be idempotent. If the upgrade hook fails, and is re run in its current state it will wipe out the backed up data. Since you didn't write this hook I spent a few cycles working over the hook and have some proposed changes, but its not 100%, as the deployment will still break the application in unknown ways.

Could you spend some time looking at upgrading the upgrade-charm hooks as well? This is an area that we need to pay extra special attention to as data integrity of existing deployments must be upheld. Thanks in advance for any cycles you can put into this. If it proves to be too difficult, let me know and i'll build off of the work you have here and attempt the upgrade.

I'm going to mark the review as needs work. When you are ready for another review be sure to click the request another review button and assign charmers. Someone will be along shortly to review your work.

If you have any questions, comments, concerns join us in #juju on irc.freenode.net and/or email the mailing list at <email address hidden>

Thanks again for all the diligent work!

Fixed various upgrade-charm bugs

[José Antonio Rey (jose)]

Hello,

The charm now upgrades fine from the current version in Juju.

The only problem presented is that apps do not migrate with the instance, but have to be activated manually.

[Charles Butler (lazypower)]

Greetings Jose,

Thanks again for your dedication in upgrading the OwnCloud charm. I'm happy to say every upgrade I've tried with this has resulted in a success.

I'm going to +1 this for now, and ask another reviewer take another look in the morning as its pretty late for me. This should go quickly and have your changes acked into the store in no time if no issues are found.

Thanks for being a champion of this effort and producing a great patch to update OwnCloud!

Hardcoded 6.0.2 instead of latest because of bug on -latest md5 hash provided by ownCloud

28. By José Antonio Rey on 2014-04-11

Removed version number from install as it may vary

[José Antonio Rey (jose)]

Hello!

Let me explain those last two revisions:

 * (rev 27) I basically hardcoded -latest into -6.0.2. This is something temporary, because the MD5 hash provided by the ownCloud community for the -latest bzip file is not up to date. Once it is, we should be able to change it back to -latest. At this moment, -latest is the same as -6.0.2, so no problems should be found.

 * (rev 28) This is a trivial change, as the install hook mentioned a 4.x version instead of just saying 'Downloading and validating', which is not up to date (even on the current charm on the charm store). Shouldn't affect the performance of the charm at all.

[Charles Butler (lazypower)]

Jose,

I have merged your changes into the charm store! Thank you so much for this submission, your dedication, and dilligence in creating an improved owncloud experience for our users. This is a welcome addition to the charm store, and again, we thank you!

+If you have been using a standalone instance and want to migrate to a shared
