tsr 0.3.0 release notes

Welcome to tsr 0.3.0!

These release notes cover the new features and backwards incompatible changes you’ll want to be aware of when upgrading from tsuru 0.2.x or older versions.

What’s new in tsr 0.3.0

Support Docker 0.7.x and other improvements

• Support all Docker storages.

The default value is 60 seconds.

Other improvements and bugfixes

• Api handler that returns information about all deploys.

Backwards incompatible changes

tsuru 0.3.0 handles quota in a brand new way. Users upgrading from 0.2.x need to run a migration script in the database. There are two scripts available: one for installations with quota enabled and other for installations without quota.

The easiest script is recommended for environments where quota is disabled, you’ll need to run just a couple of commands in MongoDB:

% mongo tsuru
MongoDB shell version: x.x.x
connecting to: tsuru
> db.users.update({}, {$set: {quota: {limit: -1}}});
> db.apps.update({}, {$set: {quota: {limit: -1}}});

In environments where quota is enabled, the script is longer, but still simple:

db.quota.find().forEach(function(quota) {
    if(quota.owner.indexOf("@") > -1) {
        db.users.update({email: quota.owner}, {$set: {quota: {limit: quota.limit, inuse: quota.items.length}}});
    } else {
        db.apps.update({name: quota.owner}, {$set: {quota: {limit: quota.limit, inuse: quota.items.length}}});
    }
});

db.apps.update({quota: null}, {$set: {quota: {limit: -1}}}); db.users.update({quota: null}, {$set: {quota: {limit: -1}}}); db.quota.remove()

The best way to run it is saving it to a file and invoke MongoDB with the file parameter:

% mongo tsuru <filename.js>
