From bd05954bfa17f03a7bd4454178ba09786b35e383 Mon Sep 17 00:00:00 2001 From: Yunlong Song Date: Thu, 2 Apr 2015 21:47:19 +0800 Subject: perf data: Support using -f to override perf.data file ownership for 'convert' Enable perf data convert to use perf.data when it is not owned by current user or root. Example: # perf record ls # chown Yunlong.Song:Yunlong.Song perf.data # ls -al perf.data -rw------- 1 Yunlong.Song Yunlong.Song 28260 Apr 2 17:35 perf.data # id uid=0(root) gid=0(root) groups=0(root),64(pkcs11) Before this patch: # perf data convert --to-ctf=./ctf-data/ File perf.data not owned by current user or root (use -f to override) # perf data convert --to-ctf=./ctf-data/ -f Error: unknown switch `f' usage: perf data convert [] -v, --verbose be more verbose -i, --input input file name --to-ctf ... Convert to CTF format After this patch: # perf data convert --to-ctf=./ctf-data/ File perf.data not owned by current user or root (use -f to override) # perf data convert --to-ctf=./ctf-data/ -f # ls ctf-data/ metadata perf_stream_0 As shown above, the -f option really works now.
