help="Run a glibc test COMMAND on the remote machine HOST, via ssh,
|
|
passing environment variables, preserving the current working directory,
|
|
and respecting quoting.
|
|
|
|
If the '--ssh SSH' flag is present, use SSH as the SSH command,
|
|
instead of ordinary 'ssh'.
|
|
|
|
To use this to run glibc tests, invoke the tests as follows:
|
|
|
|
$ make test-wrapper='ABSPATH/cross-test-ssh.sh HOST' tests
|
|
|
|
where ABSPATH is the absolute path to this script, and HOST is the
|
|
name of the machine to connect to via ssh.
|
|
|
|
If you need to connect to the test machine as a different user, you
|
|
may specify that just as you would to SSH:
|
|
|
|
$ make test-wrapper='ABSPATH/cross-test-ssh.sh USER@HOST' tests
|
|
|
|
Naturally, the remote user must have an appropriate public key, and
|
|
you will want to ensure that SSH does not prompt interactively for a
|
|
password on each connection.
|
|
|
|
HOST and the build machines (on which 'make check' is being run) must
|
|
share a filesystem; all files needed by the tests must be visible at
|
|
the same paths on both machines.
|
|
|
|
${progname} runs COMMAND in the same directory on the HOST that
|
|
${progname} itself is run in on the build machine.
|
|
|
|
The command and arguments are passed to the remote host in a way that
|
|
avoids any further shell substitution or expansion, on the assumption
|
|
that the shell on the build machine has already done them
|
|
appropriately.
|
|
|
|
${progname} propagates the values all environment variables through to
|
|
the remote target, except the following:
|
|
${env_blacklist}"
