This approximately exists now via T11968.

This is somewhat implemented by D21315, which is headed to master soon. See also T13546 and T12876.

Thanks! I didn't know it could be done from the web UI.

You can open the revision in the web UI and "Request Review". You can use arc diff --browse ... to open the web UI automatically.

We just found a real issue with this, different from what I mentioned above: We had an issue with our CI machine, and to fix it we needed to make a diff. But as the CI machine is not working, the diff won't build, which means we can't accept the diff that will solve the issue.

Is there a way to disable this option via a config in the server or a CLI parameter?

I'm planning to support this in the arc experimental branch, although initial support won't be optimized. We can look at ControlPath and/or adding batching to the protocol layer to improve performance once it works.

Any update on when this is going to reach stable? We're ~16 weeks past the earlier estimate...

The complexity of handling this makes adding a "the whole repository is caught up, deal with it" from T4453#13 sort of step more attractive. This would be far easier to motivate if we had more stuff that suffered from similar issues, though.

You will soon be able to give builds different "Hold Drafts" behaviors. See T13258.

I do have a real-life example where the prose diff engine rendered a suboptimal diff. I was able to fix it by changing the maximum length of the edit distance matrix from 128 to 256.

A specific subcase here is when the binding to an Almanac host has been disabled. We should possibly test this during Interface construction, treat it as a failure, then recover from it.

I think this has failed to collect any compelling use cases in several years and don't plan to pursue it.

@bgamari Did you ever find a solution?

@epriestley, can you confirm that the above patch should disable the draft state? I have applied it to GHC's Phabricator deployment yet we are still seeing Differentials opened in draft state.

GHC recently upgraded its Phabricator installation and has been rather unpleasantly affected by this feature. We have multi-hour CI jobs, which often queue to a day or so of builds. Making contributors wait this long before receiving feedback is turning out to be rather problematic.

See Planning.

Is there someone working on this feature?

I'm going to roll this forward into T13069, which discusses remaining work for "mail stamps".

No.

@epriestley Are there any more concrete plans for this "nonblocking" builds? That is something we would like to utilise for one of our projects. Actually quite important as waiting for builds there is slowing us down quite a bit now.
