            Bug ID: 5518
           Summary: blackbox silently drops content if it does not log
                    anything with the repo ui
           Product: Mercurial
           Version: default branch
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: bug
          Priority: wish
         Component: blackbox
          Assignee: bugzilla at mercurial-scm.org
          Reporter: arcppzju+hgbug at gmail.com
                CC: mercurial-devel at mercurial-scm.org

With the following config:

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > blackbox=
  > [blackbox]
  > track = commandexception
  > EOF



And a problematic extension that raises in a command:

  from mercurial import cmdutil
  cmdtable = {}
  command = cmdutil.command(cmdtable)
  @command('crash', [], 'crash')
  def crash(*args):
      raise 1

Blackbox cannot log the exception.

But if the config is changed to "track = command, commandexception", blackbox
can log the exception.
