Test stream-clone raced by a revlog-split | ||||
========================================= | ||||
Test stream-clone where the file is split right after the lock section is done | ||||
Start the server | ||||
$ hg serve -R server \ | ||||
> -p $HGPORT1 -d --error errors.log --pid-file=hg.pid \ | ||||
> --config extensions.stream_steps="$RUNTESTDIR/testlib/ext-stream-clone-steps.py" | ||||
$ cat hg.pid >> $DAEMON_PIDS | ||||
Start a client doing a streaming clone | ||||
$ (hg clone -q --stream -U http://localhost:$HGPORT1 clone-while-split > client.log 2>&1; touch "$HG_TEST_STREAM_WALKED_FILE_3") & | ||||
Wait for the server to be done collecting data | ||||
$ $RUNTESTDIR/testlib/wait-on-file 10 $HG_TEST_STREAM_WALKED_FILE_1 | ||||
trigger a split | ||||
$ dd if=/dev/zero of=server/$file bs=1k count=128 > /dev/null 2>&1 | ||||
$ hg -R server ci -m "triggering a split" --config ui.timeout.warn=-1 | ||||
unlock the stream generation | ||||
$ touch $HG_TEST_STREAM_WALKED_FILE_2 | ||||
wait for the client to be done cloning. | ||||
$ $RUNTESTDIR/testlib/wait-on-file 10 $HG_TEST_STREAM_WALKED_FILE_3 | ||||
Check everything is fine | ||||
