Thanks @robinsherwood for report.

we used to package the tmp/ folder but seems not the case since 2.10.0 or so -

Tasks

• add back tmp folder with .gitkeep file
• add unit test to make sure the tmp/ folder is there in Piwik

I've pushed the folder back, which permissions was it supposed to be, 755?

In my active running install it is 755

• I'm not sure now what it should be but it's important to set same permission as it was before it was removed
• let's add an automated test that will detect in case the folder is missing in the future

The test was added in the commit already.

I've downloaded Piwik 2.9.0 and the permissions are 755, so I'll apply those permissions.

Turns out that git doesn't store permissions, so it's now just like it was before.

@mnapoli could you add a unit test to verify the tmp/ folder is in git? i'm afraid otherwise we may delete it again without noticing.

Ok I see now that the test exists already in 2f524cc 👍

yes that's what I said in the comment above ;)
