commit 58de565988160edec1fc5f0fbc2a794a765bce6f
Author: George Kadianakis <desnacked at riseup.net>
Date: Thu Feb 28 12:09:10 2019 +0200
Call practracker as part of check-local.
- Introduce 'make check-best-practices'.
- Fix up Tor topdir etc to work with the way 'make check-local' gets called.
- Make practracker less likely to print useless stuff.

-Tor code best-practices tracker
+Best-practices tracker for Tor source code.
Go through the various .c files and collect metrics about them. If the metrics
violate some of our best practices and they are not found in the optional
-exceptions file ("./exceptions.txt"), then log a problem about them.
-
-The exceptions file is meant to be initialized with the current state of the
-source code as follows: ./practracker.py > ./exceptions.txt
+exceptions file, then log a problem about them.
We currently do metrics about file size, function size and number of includes.
-TODO:
- - How is this tool supposed to be used? How should the exception file work?
- How should the UI work? Does it need special exit codes?
- - Fix the function_length function so that practracker_tests.py passes.
+practracker.py should be run with its second argument pointing to the Tor
+top-level source directory like this:
+ $ python3 ./scripts/maint/practracker/practracker.py .
+
+The exceptions file is meant to be initialized once with the current state of
+the source code and then get saved in the repository for ever after:
+ $ python3 ./scripts/maint/practracker/practracker.py . > ./scripts/maint/practracker/exceptions.txt
