taucmdr.cli.commands.system.fetch.fetch_sources(dest, sources)

Download source archives into a directory, trying each archive’s mirrors in order.

A download that isn’t a readable archive, such as a server’s error page, counts as a failed mirror. The TAU nightly archive changes every day, so it’s downloaded again and stored with today’s date (see complete_nightly_names).

Parameters:

• dest (str) – Directory to download into. It’s created if it doesn’t exist.

• sources (dict) – Archive file names mapped to lists of URLs, as from all_sources.

Returns:

Names of the archives that couldn’t be downloaded from any mirror and weren’t already in dest.

Return type:

list
