Make DEBUG macro accept variable number of arguments, thus removing the need to wrap the format string and its arguments into parens on invocation.
Nack.
Please do us a favor and split this into two patches, one that makes the change to the macro definition and one that bulk-updates the existing messages. Having a 2.2MB patch file with a few small changes buried in it somewhere is very difficult to review. I'm not confident I can locate the real changes amidst the find-replace noise.
I would not want to consider such a patch in any case. The churn is just too extraordinarily big and I do not see enough value to warrant it.
The patch is so immense that is it impossible to review, so we would have to make a leap of faith in assuming every single change did not introduce errors.
I'll try to reduce the amount of faith required. Maybe try a semantic patch [1], or do some metrics on the code and the changes.
I am not against 'simplifying' the debug macro if possible, but then it should probably be done in a backwards compatible way and debug statements changed in time, just like we did when we switched from mere numbers to error type definitions.
For example we could call the new macro DBG, an start using it in place of DEBUG in new code. DEBUG would be just a wrapper around DBG that maintains the old interface.
I would advise against that. This will hurt maintainability, and I think having two ways to specify debug level is harmful as well. This is how software rot happens. It is better to have a way to verify that such changes don't break anything (tests?) and do a change globally, or not change anything at all.
However, this is of course entirely up to you and I won't push this further as I'm only doing it for a sport, while waiting for Beaker job queue to unclog.
Sincerely, Nick
