It looks the recent Python3 change (
WT-4695) triggered the application of a stricter Python formatting standard, which failed the "s_all" verification as below, on one of our development environments.
Please note the problem needs a code compilation to surface. Jenkins pull request test (wiredtiger-pull-request-builds) did not fail, as the "s_all" verification is currently set to execute without a prior compilation step.
We should either fix above errors picked up by the 'stricter' Python formatting standard, or revert to the previous checking standard and coordinate a smoother enabling of the 'stricter' formatting standard.
The Jenkins pull request test needs to be evaluated/enhanced to be able to catch such errors in the future.
