Resolves: #999
This code adds a context field for the Indicator that can be used for download_file.
This has to be integrated with the
Indicator
to synchronize the output, otherwise it leads to corruption/racey output sinceProgressIndicator.auto
writes from a second thread.Based on that requirement I opted to use a class field to store this context, as otherwise almost every function involved in dependency resolution got an
indicator
argument to feed it todownload_file
. This felt extremely noisy, and also hit some circular imports.
