From 3c426eccc29e38301774e90adeea336642826b0c Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Mon, 16 Jul 2018 23:53:21 -0700 Subject: [PATCH] gc: improve handling of errors reading gc.log A collection of minor error handling fixes: - use an error message in lower case, following the usual style - quote filenames in error messages to make them easier to read and to decrease translation load by matching other 'stat' error messages - check for and report errors from 'read', too - avoid being confused by a gc.log larger than INT_MAX bytes Noticed by code inspection.
