New issue 2700: slow warmup running Firefox taskgraph generation https://bitbucket.org/pypy/pypy/issues/2700/slow-warmup-running-firefox-taskgraph
Chris AtLee: To reproduce: - clone https://hg.mozilla.org/mozilla-central revision 2e4bef09de27 - download https://queue.taskcluster.net/v1/task/dcvqqnj4RkaJGACao955TA/runs/0/artifacts/public/parameters.yml - run `time pypy ./mach taskgraph target -p parameters.yml > /dev/null` this takes about 20s on my system next, modify taskcluster/mach_commands.py so that we duplicate the call to show_taskgraph: ``` diff --git a/taskcluster/mach_commands.py b/taskcluster/mach_commands.py --- a/taskcluster/mach_commands.py +++ b/taskcluster/mach_commands.py @@ -79,16 +79,17 @@ class MachCommands(MachCommandBase): @ShowTaskGraphSubCommand('taskgraph', 'full', description="Show the full taskgraph") def taskgraph_full(self, **options): return self.show_taskgraph('full_task_graph', options) @ShowTaskGraphSubCommand('taskgraph', 'target', description="Show the target task set") def taskgraph_target(self, **options): + self.show_taskgraph('target_task_set', options) return self.show_taskgraph('target_task_set', options) @ShowTaskGraphSubCommand('taskgraph', 'target-graph', description="Show the target taskgraph") def taskgraph_target_taskgraph(self, **options): return self.show_taskgraph('target_task_graph', options) @ShowTaskGraphSubCommand('taskgraph', 'optimized', ``` re-run `mach taskgraph`. This time is takes about 34 seconds. I think this means that the second pass only takes 14 seconds to run. _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
