Description of proposed changes

To cut down on our Continuous Integration's installation time (~9 min on Windows), let's replace conda with a more efficient installer called mamba! Specifically using mambaforge which is a faster miniconda replacement that defaults to using the conda-forge channel and mamba instead of conda by default.

Continuation of #813 which sped up our Continuous Documentation builds.

Update September 2021: Below shows comparison on Windows - Python 3.9 with a 5min speedup (18m44s -> 13m42s), this is without caching.

Old using conda (18m 44s) New using mamba (13m 42s)

Reminders

  • Run make format and make check to make sure the code follows the style guide.
  • Add tests for new features or tests that would have caught the bug that you're fixing.
  • Add new public functions/methods/classes to doc/api/index.rst.
  • Write detailed docstrings for all functions/methods.
  • If adding new functionality, add an example to docstrings or tutorials.

Slash Commands

You can write slash commands (/command) in the first line of a comment to perform
specific operations. Supported slash commands are:

  • /format: automatically format and lint the code
  • /test-gmt-dev: run full tests on the latest GMT development version

Should we try the cache action?

Sure, feel free to try it out in this branch. I'll be heading out for most of the day.

As you can see, caching (bf1e97d) doesn't help.

See PR #932 for another test. It's clear that fewer packages mean faster speed.

I've reverted the caching step, and configured setup-miniconda to use strict channel priority (conda-forge only, with no packages from default anaconda channel) which speeds up the conda/mamba resolver step (see https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-channels.html#strict-channel-priority). See if this looks ok @seisman.

It looks great. Maybe also update ci_docs.yml, cache_data.yml and even vercel's package.json file.

Ok, updated ci_docs.yml and cache_data.yml to use mamba! I won't update the vercel package.json file because using micromamba didn't seem to give a noticeable speedup last time we tried (ref #813 (review)).

Thanks @seisman, I'll merge this PR on second approval or in ~12 hours, and that should give us some good CI time savings!

Don't forget to remove the python-version: 3.7 line before merging.

* Set strict channel priority to conda-forge only with no
defaults to see if it speeds up resolver. See also
https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-channels.html#strict-channel-priority

* Use mamba on GMT Dev Tests CI build
* Use mamba in CI docs and Cache Data workflows
* Pin gmt dev version to 6.3 on Windows CI
