tests: make test-worker.t pass on py2 I broke the py2 version in https://phab.mercurial-scm.org/D9287 because the `WorkerError.__bytes__()` (or `.__str__()`?) output was different in py2 compared to py3. Part of the problem was that I didn't propagate the status code that was passed in to the superclass so it could get printed. This patch fixes that. I don't know how it worked on py3 before this patch... I also added the usual `__bytes__ = _tobytes` override for good measure. It doesn't seem to be needed for tests to pass, though.

Checking the size/permissions/file-type of files stored in the
dirstate after an update where the files are changed concurrently
outside of hg's control.

  $ hg init repo
  $ cd repo
  $ echo a > a
  $ hg commit -qAm _
  $ echo aa > a
  $ hg commit -m _

  $ hg debugdirstate --no-dates
  n 644          3 (set  |unset)               a (re)

  $ cat >> $TESTTMP/dirstaterace.py << EOF
  > from mercurial import (
  >     extensions,
  >     merge,
  > )
  > def extsetup(ui):
  >     extensions.wrapfunction(merge, 'applyupdates', wrap)
  > def wrap(orig, *args, **kwargs):
  >     res = orig(*args, **kwargs)
  >     with open("a", "w"):
  >         pass # just truncate the file
  >     return res
  > EOF

Do an update where file 'a' is changed between hg writing it to disk
and hg writing the dirstate. The dirstate is correct nonetheless, and
so hg status correctly shows a as clean.

  $ hg up -r 0 --config extensions.race=$TESTTMP/dirstaterace.py
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ echo a > a; hg status; hg diff
