maximum recursion depth exceeded in dispatch.py/util.py

[Dominik Psenner]

Hi list,

I'm moving this from thg-dev to this list since Steve B. believes this bug
is unrelated to thg.

To summarize what we've found out so far:

After several days working with the thg-workbench, mercurial decided to run
into an infinite recursion between mercurial/util.py:385 and
mercurial/dispatch.py:345 using Mercurial-1.9+10-e9264b45237d.

During the past days all worked just fine. I've seen no errors with the
commands push, pull, rebase, mq, incoming, outgoing or others that are not
wanted behaviour. But after some time thg-workbench gets into a state where
it is no longer able to push changes and this gets caught in the console
output:

Exception RuntimeError: 'maximum recursion depth exceeded while calling a
Python object' in <type 'exceptions.AttributeError'> ignore
Traceback (most recent call last):

AttributeError: 'cmdalias' object has no attribute 'shell'

Since it works just fine for days and thg-workbench works just fine when I
start a new process, it should be something cached at runtime.

Steve asked me for my aliases since they are the prime cause for the
symptom. This is what I've defined:

[alias]
latest = log --limit 5
push = push --new-branch
diff = diff -a

But still it is unclear to me why these aliases work fine for several days.
Any Ideas?

Greetings,
D.
