incorrect extension on resource upload

[Jay R. Wren]

Just trying out the new resources feature and this surprised me when upgrading a charm:

$ juju upgrade-charm crap --resource one=ugh-error.log --resource two=TODO
Added charm "cs:~evarlast/thing-1" to the model.
ERROR PUT https://10.0.5.23:17070/model/cc9dc4ee-2332-4d3b-8adc-576e02855ab1/services/crap/resources
/one?pendingid=c7d0751f-2d8f-4483-83d2-875b853feade: incorrect extension on resource upload "ugh-err
or.log", expected ""

Apparently it doesn't like the filename "ugh-error.log" but if I use a file with name without extension it succeeds.

$ juju version
2.0-beta7-xenial-amd64

same tools version. (2.0-beta7.1)

built today from master commit 1b5c7104af94ab143820a917bf8ef8434582bd29

The filename suffix of the uploaded file must match the suffix of the filename in the charm metadata. Presumably that field in the charm metadata was set to a name without a file extension.

So while the behavior is as designed (intended as a sanity check in lieu of full mime-type inspection, for better or worse), the error message is not very clear. Would something like the following have been more helpful?

    ERROR PUT https://10.0.5.23:17070/model/cc9dc4ee-2332-4d3b-8adc-576e02855ab1/services/crap/resources
/one?pendingid=c7d0751f-2d8f-4483-83d2-875b853feade: filename extension on resource upload "ugh-err
or.log" does not match filename in resource definition in charm metadata (expected "")

Also, I was going to ask what we could do to improve the docs, but it looks like the docs don't yet mention resources. :( I've opened a separate bug for that (https://github.com/juju/docs/issues/1079).

...and if you think something else is afoot, please post the charm's metadata (at least the resources part) here. Thanks!

[Jay R. Wren (evarlast)]

Ah! I had no idea that there was such a restriction.

Yes, I think the different error message would have made things more clear.

Thanks.

Thanks for verifying, Jay.

We'll work on improving the error message.

We will also look at adding an extra sentence to the help text of the CLI (attach, deploy, upgrade-charm) that explicitly states the requirement on the filename suffix.
