Arcanist could query version information via Conduit
Closed, WontfixPublic
Actions

Description

Developers can be lazy and/or just not care about running an up-to-date version of Arcanist. OTOH our Phabricator install is usually pretty-much up-to-date.

Whenever devs email me with errors they are having with Arcanist, my number one advice is to tell them to update. It would be useful if arc could perform a conduit call to query if some feature is available in a newer version. This obviously won't work for all features, but seems feasible for:

  • Does a linter exist?
  • Does a linter code exist?
  • Does a command exist?

Actually, if this seems reasonable then I should be able to work on it.

These things seem kind of rare/weird/dependent on external things? Maybe I'm just not imagining the kinds of issues users are running into.

If we did something dead simple like:

  • When an exception occurs, check if arcanist/ is on master, a valid Git repo, and behind origin/master.
  • If it is, print out an additional message, after the existing "run with --trace for a full trace", like:
IMPORTANT: Your copy of arcanist is out of date. Run arc upgrade to update it. Updating often resolves problems.

Would that get us like 20% of the way there or like 80%?

I guess maybe that would get us half-way there. As in, it would allow us to say that upgrading might solve the problem, whereas a Conduit call could allow us to say whether upgrading would solve the problem. Just not sure if its worth the effort.
