From 789b3effec89e6f336726de109eb8be9dc60b7a5 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 23 Mar 2017 17:07:11 +0100 Subject: [PATCH] sequencer: make commit options more extensible So far every time we need to tweak the behaviour of run_git_commit() we have been adding a "int" parameter to it. As the function gains parameters and different callsites having different needs, this is becoming a maintenance burden. When a new knob needs to be added to address a specific need for a single callsite, all the other callsites need to add a "no, I do not want anything special with respect to the new knob" argument. Consolidate the existing four parameters into a flag word to make it more maintainable, as we will be adding a new one to the mix soon.
