| 26 | help="Run a glibc test COMMAND on the remote machine HOST, via ssh, |
| 27 | preserving the current working directory, and respecting quoting. |
| 28 | |
| 29 | If the '--ssh SSH' flag is present, use SSH as the SSH command, |
| 30 | instead of ordinary 'ssh'. |
| 31 | |
| 32 | If the '--timeoutfactor FACTOR' flag is present, set TIMEOUTFACTOR on |
| 33 | the remote machine to the specified FACTOR. |
| 34 | |
| 35 | To use this to run glibc tests, invoke the tests as follows: |
| 36 | |
| 37 | $ make test-wrapper='ABSPATH/cross-test-ssh.sh HOST' tests |
| 38 | |
| 39 | where ABSPATH is the absolute path to this script, and HOST is the |
| 40 | name of the machine to connect to via ssh. |
| 41 | |
| 42 | If you need to connect to the test machine as a different user, you |
| 43 | may specify that just as you would to SSH: |
| 44 | |
| 45 | $ make test-wrapper='ABSPATH/cross-test-ssh.sh USER@HOST' tests |
| 46 | |
| 47 | Naturally, the remote user must have an appropriate public key, and |
| 48 | you will want to ensure that SSH does not prompt interactively for a |
| 49 | password on each connection. |
| 50 | |
| 51 | HOST and the build machines (on which 'make check' is being run) must |
| 52 | share a filesystem; all files needed by the tests must be visible at |
| 53 | the same paths on both machines. |
| 54 | |
| 55 | ${progname} runs COMMAND in the same directory on the HOST that |
| 56 | ${progname} itself is run in on the build machine. |
| 57 | |
| 58 | The command and arguments are passed to the remote host in a way that |
| 59 | avoids any further shell substitution or expansion, on the assumption |
| 60 | that the shell on the build machine has already done them |
| 61 | appropriately." |
