Package: diffoscope
Version: 30
Hangs on device files:
$ sudo mknod device-a c 5 1
$ sudo mknod device-b c 5 1
$ ./diffoscope.py --debug device-a device-b
DEBUG compare files <<class
'diffoscope.comparators.binary.FilesystemFile'> device-a None> and
<<class 'diffoscope.comparators.binary.FilesystemFile'> device-b
None>
DEBUG <<class 'diffoscope.comparators.binary.FilesystemFile'>
device-a device-a> has_same_content <<class
'diffoscope.comparators.binary.FilesystemFile'> device-b device-b>
5, 1 is /dev/console. This simply hangs in a read(2) call which never
returns. If you use "7 1" (ie. /dev/full) diffoscope will attempt to
read the entire file with predictable results.
A quick glance of the code suggests that we attempt to compare the
contents of the file *before* specialising, but even if I make a special
exception for device files here I seem to push the error elsewhere.
