This makes the download process use a temporary file and atomic file replacements on success. Allows existing files to be re-downloaded, which was not possible before. On the contrary, it will re-download files even if they didn't change. Signed-off-by: Tom Wieczorek <twieczorek@mirantis.com>
Returns a context that times out after a specified period of inactivity. It provides a "keep alive" mechanism to reset the timeout based on recent activity, ensuring that the context will remain valid for as long as there is activity. Signed-off-by: Tom Wieczorek <twieczorek@mirantis.com>
Moves the private implementation from the integration tests into the regular code base. This adapter is useful from time to time. Signed-off-by: Tom Wieczorek <twieczorek@mirantis.com>
Cancel downloads whenever there's no data flowing for a certain amount of time. Use k0scontext.WithInactivityTimeout for that. Signed-off-by: Tom Wieczorek <twieczorek@mirantis.com>
This will ensure that the download will fail at some point, even if the remote server is artificially slow. Signed-off-by: Tom Wieczorek <twieczorek@mirantis.com>

Description
Cancel downloads whenever there's no data flowing for a certain amount of time. Add a very long overall timeout for Autopilot downloads. This will ensure that the download will fail at some point, even if the remote server is artificially slow.
Add
k0scontext.WithInactivityTimeout, which returns a context that times out after a specified period of inactivity. It provides a "keep alive" mechanism to reset the timeout based on recent activity, ensuring that the context will remain valid for as long as there is activity. This is used to implement the cancellation of stale downloads.Move the private
