All touched Python scripts already assume and require UTF8, so manually
specifying encoding or decoding for functions in the subprocess module
is redundant to just using text=True, which exists since Python 3.7
Historically, the headers have been bumped some time after a file has
been touched. Do it now to avoid having to touch them again in the
future for that reason.
-BEGIN VERIFY SCRIPT-
sed -i --regexp-extended 's;( 20[0-2][0-9])(-20[0-2][0-9])? The Bitcoin Core developers;\1-present The Bitcoin Core developers;g' $( git show --pretty="" --name-only HEAD~0 )
-END VERIFY SCRIPT-
The encoding arg is confusing, because it is not applied consistently
for all IO.
Also, it is useless, as the majority of files are ASCII encoded, which
are fine to encode and decode with any mode.
Moreover, UTF-8 is already required for most scripts to work properly,
so setting the encoding twice is redundant.
So remove the encoding from most IO. It would be fine to remove from all
IO, however I kept it for two files:
* contrib/asmap/asmap-tool.py: This specifically looks for utf-8
encoding errors, so it makes sense to sepecify the utf-8 encoding
explicitly.
* test/functional/test_framework/test_node.py: Reading the debug log in
text mode specifically counts the utf-8 characters (not bytes), so it
makes sense to specify the utf-8 encoding explicitly.
Instead of having gpg.sh check against the trusted keys for a valid
signature, do it inside of verify-commits itself.
This also allows us to use the same trusted-keys throughout the
verify-commits.py check rather than it possibly being modified during
the clean merge check.
Removing the 'universal_newlines' and 'encoding' args from the subprocess.check_outputs fuction. 'universal_newlines' is supported in 3.4, but 'encoding' is not. Without specifying 'encoding' it will make a guess at encoding, which can break things on BSD systems. We must handle encoding/decoding ourselves until we can use Python 3.6
