Closed migrators not removed from conda-smithy's cache

[jakirkham]

When a migrator is closed, conda-smithy still hangs onto the migrator in cache and doesn't remove it. As a result re-rendering locally can leave closed migrators in

One possible fix would be for conda-smithy to recheck its cache contents against the migrator source and remove any that are no longer included upstream

Maybe this would make sense to do as part of this cache refreshing step

conda-smithy/conda_smithy/configure_feedstock.py

Line 2259 in f1456a3

A workaround for this would be to purge the local migrator cache and try again

For my system, this looks like...

rm -rf ~/.cache/conda-smithy/share/conda-forge/migrations

I do a lot of local rerendering, so this bug has caused me a lot of confusion. Is there any way we can prioritize fixing this? It is disorienting when the local rerendering doesn't match the bot's rerendering. I know I can simply delete the local cache, but that is exactly the thing I will forget to remember to do when I am in a hurry.

Also note that deleting ~/.cache/conda-smithy/share/conda-forge/migrations was insufficient to fix the problem for me. I had to delete ~/.cache/conda-smithy/ entirely for conda-smithy to delete the old migration files. For details please see conda-forge/tiledb-feedstock#298 (comment)

PRs welcome. You probably need to delete the folder at

conda-smithy/conda_smithy/configure_feedstock.py

@jakirkham what did you mean to end this sentence with?

When a migrator is closed, conda-smithy still hangs onto the migrator in cache and doesn't remove it. As a result re-rendering locally can leave closed migrators in

In what are the closed migrators left?

I noticed smithy hung in this codepath, which made me create #1972 - not sure if this is related or not.

In what are the closed migrators left?

In the local cache directory, which on Ubuntu is ~/.cache/conda-smithy/share/conda-forge/migrations
