profiling: add statprof support for Chrome trace viewer rendering
We synthesize function call begin/end events from snapshots, and
try (configurably) to eliminate "noisy" stack frames.
Example invocation:
hg --config profiling.output=$HOME/Desktop/clone.json \
--config profiling.statformat=chrome \
--profile clone https://www.mercurial-scm.org/repo/hg
#!/usr/bin/env python
#
# A portable replacement for 'seq'
#
# Usage:
# seq STOP [1, STOP] stepping by 1
# seq START STOP [START, STOP] stepping by 1
# seq START STEP STOP [START, STOP] stepping by STEP

import sys
start = 1
if len(sys.argv) > 2:
start = int(sys.argv[1])
step = 1
if len(sys.argv) > 3:
step = int(sys.argv[2])
stop = int(sys.argv[-1]) + 1
for i in xrange(start, stop, step):
print(i)
