Thread: [HACKERS] Compiler warning
I am seeing this compiler warning in the 9.4 branch: 9.4: basebackup.c:1284:6: warning: variable 'wait_result' set but not used [-Wunused-but-set-variable] This is on Debian Jessie with gcc version 4.9.2. It is from this commit: commit f6508827afe76b2c3735a9ce073620e708d60c79Author: Magnus Hagander <magnus@hagander.net>Date: Mon Dec 19 10:11:04 2016+0100 Fix base backup rate limiting in presence of slow i/o When source i/o on disk was too slow compared to therate limiting specified, the system could end up with a negative value for sleep that it never got out of, whichcaused rate limiting to effectively be turned off.
