From 65acfeacaa6e50c92a6ac18dc08356026a99b3f3 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 30 Sep 2016 17:19:35 -0700 Subject: abbrev: add FALLBACK_DEFAULT_ABBREV to prepare for auto sizing We'll be introducing a new way to decide the default abbreviation length by initialising DEFAULT_ABBREV to -1 to signal the first call to "find unique abbreviation" codepath to compute a reasonable value based on the number of objects we have to avoid collisions. We have long relied on DEFAULT_ABBREV being a positive concrete value that is used as the abbreviation length when no extra configuration or command line option has overridden it. Some codepaths wants to use such a positive concrete default value even before making their first request to actually trigger the computation for the auto sized default. Introduce FALLBACK_DEFAULT_ABBREV and use it to the code that attempts to align the report from "git fetch". For now, this macro is also used to initialize the default_abbrev variable, but the auto-sizing code will use -1 and then use the value of FALLBACK_DEFAULT_ABBREV as the starting point of auto-sizing.
