The expectation is to prefetch the stuff required for working with the draft commits which happens to be only revision 5 in this case. $ rm -rf $CACHEDIR/master The tree prefetching code path fetches no trees for revision 5. However, the file prefetching code path fetches 1 file for revision 5 and while doing so, also fetches 3 trees dealing with the tree manifest of the base revision 2. $ hg prefetch fetching tree 'subdir' ddb35f099a648a43a997aef53123bce309c794fd 1 trees fetched over * (glob) 1 files fetched over 1 fetches - (1 misses, 0.00% hit ratio) over * (glob) (?) Prefetching with treemanifest.ondemandfetch=True should fall back to normal fetch is the server doesn't support it. $ rm -rf $CACHEDIR/master $ hg prefetch --config treemanifest.ondemandfetch=True fetching tree 'subdir' ddb35f099a648a43a997aef53123bce309c794fd 1 trees fetched over 0.00s Running prefetch in the master repository should exit gracefully $ cd ../master $ hg prefetch
