Testing a clone bundles that involves revlog splitting (issue6811)
==================================================================
$ cat >> $HGRCPATH << EOF
> [format]
> revlog-compression=none
> use-persistent-nodemap=no
> EOF
$ hg init server-revlog-split/
$ cd server-revlog-split

$ echo foo > A
$ hg add A
$ hg commit -m 'initial commit'
IMPORTANT: the revlogs must not be split
$ ls -1 .hg/store/00manifest.*
.hg/store/00manifest.i
$ ls -1 .hg/store/data/_a.*
.hg/store/data/_a.i
do big enough update to split the revlogs
$ $TESTDIR/seq.py 100000 > A
$ mkdir foo
$ cd foo
$ touch `$TESTDIR/seq.py 10000`
$ cd ..
$ hg add -q foo
$ hg commit -m 'split the manifest and one filelog'
IMPORTANT: now the revlogs must be split
$ ls -1 .hg/store/00manifest.*
.hg/store/00manifest.d
.hg/store/00manifest.i
$ ls -1 .hg/store/data/_a.*
.hg/store/data/_a.d
.hg/store/data/_a.i
Add an extra commit on top of that
$ echo foo >> A
$ hg commit -m 'one extra commit'
$ cd ..
Do a bundle that contains the split, but not the update
$ hg bundle --exact --rev '::(default~1)' -R server-revlog-split/ --type gzip-v2 split-test.hg
2 changesets found
$ cat > server-revlog-split/.hg/clonebundles.manifest << EOF

start the necessary server
$ "$PYTHON" $TESTDIR/dumbhttp.py -p $HGPORT1 --pid http.pid
$ cat http.pid >> $DAEMON_PIDS
$ hg -R server-revlog-split serve -d -p $HGPORT --pid-file hg.pid --accesslog access.log
$ cat hg.pid >> $DAEMON_PIDS
Check that clone works fine
===========================
Here, the initial clone will trigger a revlog split (which is a bit clowny it
itself, but whatever). The split revlogs will see additionnal data added to
them in the subsequent pull. This should not be a problem
