admin-verify: pass p1 down to the dirstate function

This was forgotten and can break with certain kinds of corruption.

Test stream cloning while a revlog split happens

  $ hg init server
  $ cd server
  $ file="some-file"
  $ printf '%20d' '1' > $file
  $ hg commit -Aqma
  $ printf '%1024d' '1' > $file
  $ hg commit -Aqmb
  $ printf '%20d' '1' > $file

check the revlog is inline

  $ f -s .hg/store/data/some-file*

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 --debug --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
