kill-wpull-connections
is a workaround for wpull‘s bug of HTTPS connections getting stuck, slowing down or entirely stopping progress (#407). It works by attaching to the process and shutting down the TCP connections directly using the shutdown
syscall. Although written for use with wpull, it can actually be used for any process.
To kill all TCP connections except those to 127.0.0.1 of a process:
kill-wpull-connections -p $PID
As a convenience option for ArchiveBot pipeline maintainers, to kill the connections of a running ArchiveBot job:
kill-wpull-connections -j $JOBID
If you get an error of
gdb.error: 'shutdown' has unknown return type; cast the call to its declared return type
then add the -c
option before -p
or -j
, e.g. kill-wpull-connections -c -p $PID
.
If you’re running wpull inside a Docker container without ptrace capabilities, you need to run kill-wpull-connections outside of the container (where you do have ptrace cap) but inside the container’s network namespace. One way to do this is:
nsenter --net=$(docker inspect $CONTAINERID | jq -r .[].NetworkSettings.SandboxKey) kill-wpull-connections -p $PID
