Use the distro module (if available) for guessing the linux distribution.
In case of python < 3.8, use the platform.linux_distribution() fallback if
no distro module is available.
Rationale: platform.linux_distribution() was dropped in python3.8
In case diff3 returns something except 0 or 1, osc errors out because the
variable merge_cmd is not defined. It used to exist, but got removed in the
past and is reintroduced via this commit.
The files are now opened as rb for diffing. In python2 nothing changes.
In python3 the returned diff is bytes now.
The following changes were made:
* commandline.py: The returned diff is now bytes
* get_diff now returs the diff as a bytes-like object
* run_pager writes with sys.stdout.buffer.write if message
is not a string
* for the commit message the returned diff needs to be decoded
now. Otherwise it will just producce garbage. For the commit
message the diff on decoded bytes-objects is ok. (nothing harmfull
can happen here)
* fixed submit_action_diff
* fixed request_interactive_review
if prjconfig meta is empty the class metafile init
fails with
if isinstance(input[0], str):
IndexError: list index out of range
This is because input is an empty list and has no
[0] index.
This can be fixed by changing this line to:
if input and isinstance(input[0], str):
simplified and fixed the __init__ method of the metafile class.
input can be string, bytes-like object, list of strings or list
of bytes-like objects now.
Based on the input now always a list is generated and joined to
a string for writing in the fd. (This is ugly but needed for
compat reasons)
opts.quiet is passed to get_binary_file which is False by default.
So the following if progress_meter is always False unless -q is given.
So it needs to be if not progress_meter.
The content in the todo dict are strings. In python3 the communicate
method expects a bytes-like object not a string.
Solution: Encode every element in todo to a new dict (enc_todo) and
pass this instead of todo
* use cmp_to_key from functools for python 2.7 and higer
* use self written cmp_to_key for python 2.6
* new functions compare und cmp (used in python2 and python3)
* a lot of bytestring handling and decoding
* fix slow rbl based on f.readline(bufsize)
