symlinks on ecryptfs cause spurious modifications

[avdd]

Binary package hint: mercurial

when syncing hg repos from or to a filesystem using ecryptfs, the sizes of the symlinks are different causing spurious modification messages.

For example, if /tmp is clear fs and $HOME is ecryptfs:

mkdir /tmp/hgtest
cd /tmp/hgtest
hg init
touch foo
ln -s foo bar
hg add foo bar
hg ci -m 'file and symlink'
hg st
sleep 3 # necessary for bug to manifest
rsync -ra /tmp/hgtest/ ~/hgtest
cd ~/hgtest
hg st

output:

M bar

git also has the same problem, svn and bzr do not

I guess we could skip the size check if it's a symlink. Could you open a bug in upstream's bugtracker ? (mercurial.selenic.com/bts)

It seems I can't do that without creating an account, hence my
report here. I though that was the point of launchpad.

Bug was closed upstream, http://mercurial.selenic.com/bts/issue2042
Best would be if ecryptfs was fixed.
