New submission from Vaclav Bartos <bar...@cesnet.cz>:
When `syslog.openlog()` is called without parameters (or `syslog.syslog()` is
called directly), the `ident` parameter should be set to "sys.argv[0] with
leading path components stripped" (citation from docs).
I suppose this means that when sys.argv[0] is "/some/path/to/script", the ident
should be set to "script" (this is the behavior in Python 2.7)
However, in Python 3.x, it gets set to "/script", i.e. the last slash is
included in the string. I suppose this is not intended, it is just a "one-off"
error in parsing the string.
The fix is trivial, see the linked GitHub PR.
To reproduce the bug:
$ python3
>>> import sys
>>> import syslog
>>> sys.argv[0] = "/some/path/to/script"
>>> syslog.syslog("TEST MESSAGE")
>>>
$ tail -n 1 /var/log/messages
Oct 3 11:11:46 localhost /script: TEST MESSAGE
