🚀 Pull Request

Description

Includes the removal of the GeoAxes monkey patch - closes #5977.

Forced to do this now since we haven't yet got Read the Docs locked down (SciTools/workflows#38), so that's already getting Cartopy v0.24 and therefore failing our CI.

#6171 (comment)

As far as I can tell: ALL collapse benchmarks have become slower. Some have not triggered the threshold. This appears to be a function of how long the benchmark takes - longer benchmarks have changed less, suggesting the regression is an overhead of some sort (the regression itself does not scale).

It's hard to tell but I believe the weighted collapse benchmarks (w_collapsed_by) have also regressed, but not by much.

The aggregated_by benchmarks appear unchanged.

There aren't many changes in the lock files, and I struggle to see how any of the changes could affect collapsing but not aggregating - they both use the same operation under the hood.

SciTools/cartopy#2414 made a minor change that had two effects for Iris:

  • Changed how plot edges might be rendered
  • Changed the aspect ratio of some plots

Did the due diligence on the image tests that had failed and confirmed that there was no evidence of something malfunctioning, just a minor visual change going forward.

As far as I can tell: ALL collapse benchmarks have become slower. Some have not triggered the threshold. This appears to be a function of how long the benchmark takes - longer benchmarks have changed less, suggesting the regression is an overhead of some sort (the regression itself does not scale).

I was hoping to replicate locally, then I could do some scalability testing, but my local results suffer from too much variance to identify these regressions (which itself demonstrates how small they are).

Regardless: the only action we could reasonably take would be to warn users of the regression (we can't fix it if it's in a dependency), but I propose that a regression this small, and one that seemingly does not scale, is not worth warning users about.

(Happy for this to be merged before the latest benchmark run finishes).
