[pacman-dev] [PATCH] alpm: Fix SIGINT handling re: aborting download
Upon receiving SIGINT a flag is set to abort the (curl) download.
However, since it was never reset/initialized, if a front-end doesn't
actually exit on SIGINT, and later tries any operation that needs to
perform a new download, said download would always get aborted right
away due to the flag not having been reset.

Variable dload_interrupted is used both to abort a download because
SIGINT was caught, and when a file limit is reached. But raising SIGINT
is only meant to happen in the first case.

I think set_handle_opts is the wrong place to reset it since it is in fact not a handle option. Let's put it right before the signal handlers are registered to keep signal-related things together.
/* the curl_easy handle is initialized with the alpm handle, so we only need * to reset the handle's parameters for each time it's used. */ curl_easy_reset(curl); -- 2.19.0
