Adds a tier 2 optimizer pass that converts the micro-ops for loading globals and builtins to constants.
This should have two benefits:

  • The resulting code is faster
  • It will enable further optimizations thanks to better constant and type propagation.

Benchmarking and stats show a ~1% speedup, but it is the stats that are interesting.

The tier 2 stats show that we have replaced 3 billion guards with 1.2 cheaper guards, and that allLOAD_GLOBAL_MODULE andLOAD_GLOBAL_BUILTINS have been replaced with inline constants.

There are some changes to the tier 1 stats, whichI think are a result of not optimizing when the global/builtin keys version doesn't match, so we avoid poor optimization. This drops us back into tier 1 for later re-optimization to tier 2, hopefully when the set of global variables has stabilized.
This shows up in the tier 1 stats and optimization attempts.
What this suggests is that we should be de-optimizing faster in tier 1 in this case, as once the keys version has changed it will never go back to the original value. But that's for another PR.

Hey@carljm, could you review the changes to the dict watcher here please? I've never seen that code before (sorry).

This looks pretty good, I mostly have suggestions for clarifying comments and a few style nits.

The dict watchers changes look good to me! Nice to see this in use.

The JIT tests are failing. We should probably force enable uops and hammer the test suite.

Maybe I'm just misunderstanding, but shouldn't this be>? As in, if we've modified builtins too many times, we invalidate everything?

Also, what is the purpose of excludingPyDict_EVENT_CLONED here?

Every time the builtins changes any executors that depend on it not changing must be invalidated.
So we invalidate the executor(s) every time it the builtins changes.
Upon reaching the threshold we no longer perform those optimizations, so the executors no longer depend on the builtins not changing, and we no longer need to invalidate.

Also, what is the purpose of excluding PyDict_EVENT_CLONED here?

Cloning doesn't modify the dict, so we don't care about it.

@carljm OOI, why does Cinder care about dict cloning?

PyDict_EVENT_CLONED is probably a bad name, because grammatically it implies the subject dict was cloned. What it actually means is that the subject dict was empty, and another dict was clonedinto it, via e.g..update(). So it does represent a change in the subject dict; all dict watcher events do.

I think it is probably irrelevant here, since it is (at least in practice) impossible(?) for builtins or module globals to be empty when code is running.

And I don't think Cinder cares about it in practice either, for that same reason, it was just for completeness in the dict watcher implementation, since all changes to a dict should be notified by dict watchers.

}

if (PyDict_Watch(interp->rare_events.builtins_dict_watcher_id,interp->builtins)!=0) {
interp->dict_state.watchers[0]=&builtins_dict_watcher;

Since the first two slots are "reserved", it might be clearer to have#defines for these slots. e.g.BUILTINS_DICT_WATCHER_ID for 0 here.

What is the rationale for bypassingPyDict_AddWatcher here and special-casing? Just a small amount of startup performance? Here, consistency and encapsulating management of thedict_state.watchers array might be better maintenance-wise.

It keeps things simpler if we are guaranteed to have IDs. Otherwise we need to worry about what happens if we can't add either or both of the watchers.

Confirmed locally that the same failures happen with tier two (not just the JIT).

⚠️⚠️⚠️ Buildbot failure⚠️⚠️⚠️

Hi! The buildbotAMD64 Ubuntu NoGIL Refleaks 3.x has failed when building commit0e71a29.

What do you need to do:

  1. Don't panic.
  2. Checkthe buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/1226/builds/1106) and take a look at the build logs.
  4. Check if the failure is related to this commit (0e71a29) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:
