1524906 - moz-phab submit CalledProcessError: hg evolve returned non-zero exit status 1

Status: NEW

(Conduit :: moz-phab, defect)

Description

[Chris Peterson [:cpeterson]]

I'm getting an error when trying to moz-phab submit:

CalledProcessError: Command '['hg', '--config', 'ui.username=Chris Peterson <[e-mail]>', '--config', 'extensions.rebase=', '--config', 'extensions.evolve=/Users/chris/.mozbuild/evolve/hgext3rd/evolve', 'rebase', '--source', 'e7befda7fddd4f9284e22366276c993edcf8507a', '--dest', '25c37e24fbccae439b98ff79608d115a1dae2083']' returned non-zero exit status 1

moz-phab appears to swallow the hg output, so i don't know why evolve is failing. I'm running hg version 4.9 (from Homebrew on macOS) and hg evolve version 8.4.0. I ran mach bootstrap today.

I successfully moz-phab submitted changesets for a new bug. The error above was for a changeset (in bug 1511763) that I had rebased on a newer central head and tried to moz-phab submit for a re-review.

After commenting out the evolve extension in my hgrc, I was able to successfully moz-phab submit.

moz-phab appears to swallow the hg output

moz-phab doesn't consume the output of hg rebase, it should be visible on your terminal preceding this error.
are you able to attach the full output to this bug?

if you hit this error again you can run with DEBUG=1 moz-phab submit to dramatically increase the verbosity of output.

Attachment: moz-phab-submit.log

Here is my DEBUG=1 moz-phab submit output.

Looks like hg evolve logs "nothing to rebase" and then returns exit status 1.

btw, this is a local error. Unbeknownst to me, the moz-phab submit was successfully uploading the patches to Phabricator (again and again and again) as I was reproducing the error message. I apologize to the people spammed by my bug mail! :)

self-ni as a reminder to investigate the log.
