Classes

PackageCacheType

This metaclass does basic caching of PackageCache instance objects.

Functions

do_cache_action(prec, cache_action, progress_bar[, ...])

This function gets called from ProgressiveFetchExtract.execute.

do_extract_action(prec, extract_action, progress_bar)

This function gets called after do_cache_action completes.

do_cleanup(actions)

do_reverse(actions)

done_callback(future, actions, progress_bar, exceptions)

rm_fetched(dist)

Checks to see if the requested package is in the cache; and if so, it removes both

execute()

Run each action in self.paired_actions. Each action in cache_actions runs before its corresponding extract_actions.

__hash__()

Return hash(self).

__eq__(other)

Return self==value.

do_cache_action(prec, cache_action, progress_bar, download_total=1.0)

This function gets called from ProgressiveFetchExtract.execute.

do_extract_action(prec, extract_action, progress_bar)

This function gets called after do_cache_action completes.

do_cleanup(actions)
do_reverse(actions)
done_callback(future: concurrent.futures.Future, actions: tuple[CacheUrlAction | ExtractPackageAction, Ellipsis], progress_bar: conda.common.io.ProgressBar, exceptions: list[Exception], finish: bool = False)
rm_fetched(dist)

Checks to see if the requested package is in the cache; and if so, it removes both the package itself and its extracted contents.
