From 79b3b48170aed5d975b8e664eb85b2a99ca578f6 Mon Sep 17 00:00:00 2001 From: Kali Kaneko Date: Sun, 9 Aug 2015 14:02:56 -0400 Subject: [feat] update profile-sync script, add plop profiling Updating the profile-sync script to the latest deferred-based sync. - Added a couple of options to have finer control about what output to get. - Add support for the plop profiler https://pypi.python.org/pypi/plop/ - To get meaningful plop profiles, make sure to disable the system stats collection, like this:: ./profile-sync.py --no-stats --plop -b /tmp/syncdata/ -p sikret user@provider A good practice for this is having a pre-seeded soledad account (currently you have to do that through the wizard, a cli will be very nice to have in the coming future) with a known amount of data (for instance, sending some mails with known payload weight). It is VERY IMPORTANT that you *NEVER* process the data in this account (ie, do not ever log in with a mail client, for instance, since that will alter the original documents). In order to have comparable results, you should always run this sync script in similar conditions. Ideally, on a machine with runlevel 1. Also, make sure of deleting the contents in the folder if you are not using a temporal dir. --- scripts/profiling/sync/profile-sync.py | 84 ++++++++++++++++++++++++++----- scripts/profiling/sync/run_plop_server.sh | 2 + scripts/profiling/util.py | 2 +- 3 files changed, 75 insertions(+), 13 deletions(-) mode change 100644 => 100755 scripts/profiling/sync/profile-sync.py create mode 100755 scripts/profiling/sync/run_plop_server.sh (limited to 'scripts') diff --git a/scripts/profiling/sync/profile-sync.py b/scripts/profiling/sync/profile-sync.py old mode 100644 new mode 100755 index fdd5b5a6..6c8d249e --- a/scripts/profiling/sync/profile-sync.py +++ b/scripts/profiling/sync/profile-sync.py @@ -1,13 +1,16 @@ -#!/usr/bin/python - +#!/usr/bin/env python import argparse +import commands +import getpass import logging +import tempfile +from datetime import datetime +from twisted.internet import reactor from util import StatsLogger, ValidateUserHandle -from client_side_db import get_soledad_instance -#from plot import plot +from client_side_db import _get_soledad_instance, _get_soledad_info # create a logger @@ -15,6 +18,15 @@ logger = logging.getLogger(__name__) LOG_FORMAT = '%(asctime)s %(message)s' logging.basicConfig(format=LOG_FORMAT, level=logging.INFO) +GITVER = commands.getoutput('git describe') + + +def get_and_run_plop_collector(): + from plop.collector import Collector + collector = Collector() + collector.start() + return collector + # main program @@ -33,6 +45,16 @@ if __name__ == '__main__': parser.add_argument( '-l', dest='logfile', required=False, default='/tmp/profile.log', help='the file to which write the log') + parser.add_argument( + '--no-stats', dest='do_stats', action='store_false', + help='skip system stats') + parser.add_argument( + '--plot', dest='do_plot', action='store_true', + help='do a graphical plot') + parser.add_argument( + '--plop', dest='do_plop', action='store_true', + help='run sync script under plop profiler') + parser.set_defaults(do_stats=True, do_plot=False, do_plop=False) args = parser.parse_args() # get the password @@ -47,16 +69,54 @@ if __name__ == '__main__': basedir = tempfile.mkdtemp() logger.info('Using %s as base directory.' % basedir) + uuid, server_url, cert_file, token = \ + _get_soledad_info( + args.username, args.provider, passphrase, basedir) # get the soledad instance - s = get_soledad_instance( - args.username, args.provider, passphrase, basedir) + s = _get_soledad_instance( + uuid, passphrase, basedir, server_url, cert_file, token) + for i in xrange(10): + # XXX Profile this with more realistic payloads s.create_doc({}) - sl = StatsLogger( - "soledad-sync", args.logfile, procs=["python"], interval=0.001) - sl.start() - s.sync() - sl.stop() + def start_sync(): + if args.do_stats: + sl = StatsLogger( + "soledad-sync", args.logfile, procs=["python"], interval=0.001) + sl.start() + else: + sl = None + + if args.do_plop: + plop_collector = get_and_run_plop_collector() + else: + plop_collector = None + + t0 = datetime.now() + d = s.sync() + d.addCallback(onSyncDone, sl, t0, plop_collector) + + def onSyncDone(sync_result, sl, t0, plop_collector): + print "GOT SYNC RESULT: ", sync_result + t1 = datetime.now() + if sl: + sl.stop() + if plop_collector: + from plop.collector import PlopFormatter + formatter = PlopFormatter() + plop_collector.stop() + # XXX mkdir profiles dir if not exist + with open('profiles/plop-sync-%s' % GITVER, 'w') as f: + f.write(formatter.format(plop_collector)) + + delta = (t1 - t0).total_seconds() + print "[+] Sync took %s seconds." % delta + reactor.stop() + + if args.do_plot: + from plot import plot + plot(args.logfile) - #plot(args.logfile) + reactor.callWhenRunning(start_sync) + reactor.run() diff --git a/scripts/profiling/sync/run_plop_server.sh b/scripts/profiling/sync/run_plop_server.sh new file mode 100755 index 00000000..7b905c3d --- /dev/null +++ b/scripts/profiling/sync/run_plop_server.sh @@ -0,0 +1,2 @@ +#!/bin/sh +python -m plop.viewer --datadir=profiles diff --git a/scripts/profiling/util.py b/scripts/profiling/util.py index adf1de8c..e7e2ef9a 100644 --- a/scripts/profiling/util.py +++ b/scripts/profiling/util.py @@ -46,7 +46,7 @@ class StatsLogger(threading.Thread): stats = [] stats.append("%f" % (now - self._start)) # elapsed time stats.append("%f" % psutil.cpu_percent()) # total cpu - stats.append("%f" % psutil.phymem_usage().percent) # total memory + stats.append("%f" % psutil.virtual_memory().percent) # total memory return ' '.join(stats) def _make_proc_stats(self): -- cgit v1.2.3
