[issue3178] Incorrect 'hg status' after permissions change when running as a different user

[Mathias De Maré]

New submission from Mathias De Maré <mathias.demare at gmail.com>:

If I change only the permissions of a particular file in my repository, I
can see the change with 'hg status'.

However, if I login as a different user and check with hg status, I can't.

This is because 'checkexec' is executed in dirstate.py. checkexec apparently
creates a file in the current directory and tries to change its permissions
(to check if exec permissions are supported). Of course this fails, because
the other user doesn't have the required access rights.

This seems like an inconsistency, and quite confusing.

To reproduce:

hg init testrepo
cd testrepo
touch foo
hg add foo
hg commit -m "Added foo."
chmod +x foo
hg status
M foo

---

su - otheruser
hg status
