Pulled, thanks Arnaldo.
Note that the old dependency related build failure thought to be
fixed in commit 860df5833e46 is back:
make[1]: *** No rule to make target
`/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'. Stop.
'make clean' itself does not work in libtraceevent:
comet:~/tip/tools/lib/traceevent> make clean
make: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'. Stop.
So I had to clean it out manually:
comet:~/tip/tools/lib/traceevent> git ls-files --others | xargs rm
comet:~/tip/tools/lib/traceevent>
and then things build fine.
I also noticed a 'perf trace' bug, after running 'perf trace' it
outputs lines but then gets hung:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
6081 mingo 20 0 18.2g 14g 3544 D 18.6 91.2 0:20.28 perf
and then after half a minute it gets active again, outputting
lines and then segfaulting:
LOST 1 events!
31082 ) = 375
31082 write(fd: 3, buf: 140030569454096, count: 48LOST 1 events!
31082 select(n: 13, inp: 140030569376688, outp: 140030569376656, exp: 0, tvp: 031082 ) = 2
Segmentation fault
It's a 16-way box running:
Linux comet 3.5.4-1.fc17.x86_64 #1 SMP Mon Sep 17 15:03:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Note how much the RSS is, 14 GB of RAM with less of 1 minute
running. The segfault might be related to a failed allocation
not being handled correctly perhaps.
Thanks,
Ingo
