New submission from Terry J. Reedy:
On my Win10-64 machine, test_winreg hangs, impervious to ^C. I have to close
Command Prompt. (With IDLE I can run just test_winreg and then Restart Shell.)
This happened with repository builds last Friday and today, and with installed
3.6.2rc1. But I believe I ran the entire test suite (to successful completion)
not too many days before.
The culprit is
def test_dynamic_key(self):
# Issue2810, when the value is dynamically generated, these
# raise "WindowsError: More data is available" in 2.6 and 3.1
try:
EnumValue(HKEY_PERFORMANCE_DATA, 0)
except OSError as e:
if e.errno in (errno.EPERM, errno.EACCES):
self.skipTest("access denied to registry key "
"(are you running in a non-interactive session?)")
raise
QueryValueEx(HKEY_PERFORMANCE_DATA, "")
Commenting out the whole function or both the EnumValue and QueryValueEx calls
(replacing the former with pass) is required to allow the test to run (and
pass).
I have no idea why behavior on my machine is different from buildbots. If the
problem is with my registry, could the test be more robust? Having to kill my
console session, and lose history, after running the test suite, is unpleasant.
