revlog: move the details of revlog "v2" index inside revlog.utils.constants
the revlog module is quite large and this kind of format information would handy
for other module. So let us start to gather this information about the format in
a more appropriate place.
We update various reference to this information to use the new "source of truth"
in the process.

Test that, when an hg push is interrupted and the remote side recieves SIGPIPE, the remote hg is able to successfully roll back the transaction. $ hg init -q remote $ hg clone -e "\"$PYTHON\" \"$TESTDIR/dummyssh\"" -q ssh://user@dummy/`pwd`/remote local $ check_for_abandoned_transaction() { > [ -f $TESTTMP/remote/.hg/store/journal ] && echo "Abandoned transaction!" > } $ pidfile=`pwd`/pidfile $ >$pidfile $ script() { > cat >"$1" > chmod +x "$1" > } 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. $ killable_pipe=`pwd`/killable_pipe.sh $ script $killable_pipe <<EOF > #!/bin/bash > echo \$\$ >> $pidfile > exec cat > EOF $ remotecmd=`pwd`/remotecmd.sh $ script $remotecmd <<EOF > #!/bin/bash > hg "\$@" 1> >($killable_pipe) 2> >($killable_pipe >&2) > EOF In the pretxnchangegroup hook, kill the PIDs recorded above to simulate ssh disconnecting. Then exit nonzero, to force a transaction rollback. $ hook_script=`pwd`/pretxnchangegroup.sh $ script $hook_script <<EOF > #!/bin/bash > for pid in \$(cat $pidfile) ; do > kill \$pid > while kill -0 \$pid 2>/dev/null ; do > sleep 0.1 > done > done > exit 1 > EOF $ cat >remote/.hg/hgrc <<EOF > [hooks] > pretxnchangegroup.break-things=$hook_script > EOF $ cd local $ echo foo > foo ; hg commit -qAm "commit" $ hg push -q -e "\"$PYTHON\" \"$TESTDIR/dummyssh\"" --remotecmd $remotecmd 2>&1 | grep -v $killable_pipe abort: stream ended unexpectedly (got 0 bytes, expected 4) $ check_for_abandoned_transaction [1]
