Test that, when an hg push is interrupted and the remote side receives SIGPIPE,
|
|
|
the remote hg is able to successfully roll back the transaction.
|
|
|
|
|
|
$ hg init -q remote
|
|
|
$ hg clone -e "\"$PYTHON\" \"$RUNTESTDIR/dummyssh\"" -q ssh://user@dummy/`pwd`/remote local
|
|
|
$ SIGPIPE_REMOTE_DEBUG_FILE="$TESTTMP/DEBUGFILE"
|
|
|
$ SYNCFILE1="$TESTTMP/SYNCFILE1"
|
|
|
$ SYNCFILE2="$TESTTMP/SYNCFILE2"
|
|
|
$ export SIGPIPE_REMOTE_DEBUG_FILE
|
|
|
$ export SYNCFILE1
|
|
|
$ export SYNCFILE2
|
|
|
$ PYTHONUNBUFFERED=1
|
|
|
$ export PYTHONUNBUFFERED
|
|
|
|
|
|
On the remote end, run hg, piping stdout and stderr through processes that we
|
|
|
know the PIDs of. We will later kill these to simulate an ssh client
|
|
|
disconnecting.
|
|
|
|
|
|
$ remotecmd="$RUNTESTDIR/testlib/sigpipe-remote.py"
|
|
|
|
|
|
In the pretxnchangegroup hook, kill the PIDs recorded above to simulate ssh
|
|
|
disconnecting. Then exit nonzero, to force a transaction rollback.
