Subject: [PATCH] automatic: Check availability of config file
|
||
|
|
||
|
Upstream commit: 13ecc3921fb1566c2af7b80d5cb515d8fc4e5ec9
|
||
|
RHEL issue: https://issues.redhat.com/browse/RHEL-49743
|
||
|
|
||
|
If a configuration file is explicitly specified on the command line,
|
||
|
ensure that it exists and is readable. If the file is not found, notify
|
||
|
the user immediately and terminate the process.
|
||
|
|
||
|
This resolves issues where users may run dnf-automatic with unrecognized
|
||
|
positional arguments, such as `dnf-automatic install`.
|
||
|
|
||
|
The most natural approach to handle a non-existing config file would be
|
||
|
by catching the exception thrown by the `read()` method of the
|
||
|
`libdnf.conf.ConfigParser` class. Unfortunately, the Python bindings
|
||
|
override the `read()` method at the SWIG level, causing it to suppress any
|
||
|
potentially raised IOError.
|
||
|

def ConfigParser__newRead(self, filenames):
|
||
|
parsedFNames = []
|
||
|
try:
|
||
|
if isinstance(filenames, str) or isinstance(filenames, unicode):

parsedFNames.append(fname)

except IOError:

|
pass
|

|
except Exception as e:

|
raise RuntimeError("Parsing file '%s' failed: %s" % (fname, str(e)))
