I'm getting the same #1048: Column 'filename' cannot be null running just regular "arc diff". It used to work and then at some point after updates started failing.

Thanks for the link. That's rather conceptual though. And things like overriding upstream landing is a thing that breaks compatibility with underlying SCM by assuming you use arc-feature. A tool specific explanation of the workflow would be great, for understanding the point of why things work the way they do. Though I'd rather the Official Workflow did not prevent other workflows. But I guess I have the power to remove that feature.

@chad: arc-patch requires a diff and pushing a branch is much simpler than creating a diff. Since we seem to be pushed into the direction of an official Phabricator workflow, is that documented somewhere? Phabricator makes assumptions about code structure, versioning and many kinds of things, but are they stated somewhere?

Severely needed. .arcconfig should be able to control where things land without arguments. I also question the choice made in D10058 where branch tracking seems to be used as a indicator of a branch created with arc-feature. Since arc-feature is in no way central to arc use, I think it should not be assumed that it will be used. And regular workflows and GUI tools will use git-branch instead, with tracking.

This is a problem for us too. People push branches to work on it on another machine.

I suppose custom fields could be used but the major issue is in retrieving the information about revisions/commits being on branch X. Documentation is lacking and I couldn't find out how Diffusion populates the Branches field. Any pointers?
