btw, same error happens when using make deb
from the 1.2 tag.
I'm using ubuntu artful 17.10 (but inside an Xorg session)
from autorandr.
I frankly don't quite understand how this can happen. Python emits this error message if the name of an environment variable contains a =
, but the way autorandr is programmed it should never try to do that.
Could you please add to autorandr.py
, after line 909,
for environ_entry in open(environ_file).read().split("\0"):
a new line
print(repr(environ_entry))
and check whether the journald log contains a suspicious entry (with a nonprintable character or multiple =
's or something like that) before the error message?
from autorandr.
Weird, I cannot reproduce this anymore. Everything works fine, besides a segault in the logs (#90).
from autorandr.
Ok, just drop a note if the bug resurfaces - closing this for now :-)
(Btw, issues with parts of this code are always semi-random, because whether they surface depends on which processes have which PIDs on your system.)
from autorandr.
Oh, there is one thing you could still try. Please run this as root and check whether it prints something:
#!/usr/bin/env python
# encoding: utf-8
import os
for directory in os.listdir("/proc"):
directory = os.path.join("/proc/", directory)
if not os.path.isdir(directory):
continue
environ_file = os.path.join(directory, "environ")
if not os.path.isfile(environ_file):
continue
process_environ = {}
for environ_entry in open(environ_file).read().split("\0"):
if "=" in environ_entry:
name, value = environ_entry.split("=", 1)
process_environ[name] = value
try:
os.environ.clear()
os.environ.update(process_environ)
except:
print(process_environ)
break
The script tries to extract the environment of all processes and update it's own environment accordingly - hopefully, this'll fail for some process.

@phillipberndt I ran it as root multiple times and it prints env variables without failure.
from autorandr.
If it prints something that's a sign of failure :) Could you share the output please?
from autorandr.
@phillipberndt : sorry, too many private env variables in the output that I don't want to share/scrape out.
from autorandr.
Fair enough. It'd suffice to extract the one, single variable which leads to the failure:
#!/usr/bin/env python
# encoding: utf-8
import os
import sys
for directory in os.listdir("/proc"):
directory = os.path.join("/proc/", directory)
if not os.path.isdir(directory):
continue
environ_file = os.path.join(directory, "environ")
if not os.path.isfile(environ_file):
continue
for environ_entry in open(environ_file).read().split("\0"):
if "=" in environ_entry:
name, value = environ_entry.split("=", 1)
try:
os.environ.clear()
os.environ.update({name: value})
except:
print(repr({name: value}))
sys.exit(0)
from autorandr.
ok, here's the output:

Looks like something from LS_COLORS
- and then it might possibly be split?! (since it tends to be very long)
@varac
You can adjust the script above to print(directory)
, which should be the PID and from there figure out what process it is.

@blueyed Thanks for your PR & the help!
@varac Thanks for the debug info! The only way I can explain myself how this happens is that the process generating the LS_COLORS
variable inserts a null-byte after one of the file extensions. I.e. ..:*.foo\0=33:*.yuv=..
. Since null-bytes separate environment variables, that's a bug, but indeed a case autorandr should handle.
