Dummy driver: Use cp --reflink=auto to copy directories
 2013-11-19 10:16:56 -08:00
Alexander Larsson 242fd4b3ef dummy driver: Use cp --reflink=auto to copy directories 
On systems that supports reflinking (i.e. btrfs) this means the dummy
backend is much faster at copying files and will be sharing file data in
a CoW fashion.

On my (btrfs) system this makes "docker run ubuntu echo hello world" go
from about 3 seconds to about 1 second. Not instant, but clearly better.

cp --reflink=auto is availible since coreutils 7.5 (around 2009), so this
seems pretty ok to rely on.

cp is also better at preserving file metadata than tar, so for instance
it will copy xattrs.

Alexander Larsson 8ed4307f50 Mark archive.TestApplyLayer as skipped 
Instead of just returning we call Skip to log that the test
was skipped.

Alexander Larsson 10f23a94f6 Use dummy driver for volumes 
It makes no sense to use the aufs or devicemapper drivers for volumes.
The aufs one is perhaps not a big problem, but the devicemapper one
certainly is. It will be unnecessarily using a dm
blockdevice-over-loopback with a limited size base FS.

This just hardcodes the driver to be the dummy, perhaps in the future
we can have other drivers that make sense for the volumes.

Alexander Larsson 243843c078 Print devicemapper status details in docker info 
This adds a generic Status call in the Driver api and
implements if for the devicemapper backend.

The status is an array of key/value strings rather than a map so that
we can guarantee some static order of the docker info output.

Alexander Larsson f7238f94e8 Add tests for the changes detection code 
This adds 3 tests:

Verify that ChangesDirs() returns nothing when run on a copy of the
same directory.

Verify that various mutations of a directory get reported with the
right changes.

Verify that ExportChanges() + ApplyLayer() of the above mutation gets
an identical directory.

Unfortunately the last test is disabled because it fails in multiple
ways atm. But I want to get it in so that we can fix it.

Alexander Larsson d69a6a20f0 Use ExportChanges() in runtime.Diff() 
This code was duplicated in two places, one which was unused. This
syncs the code and removes the unused version.

Michael Crosby 4908d7f81d Save driver to container and skip incompat containers 
For people who toggle drivers we want to save the driver used
to create a container so that if the driver changes we can skip
loading the container and it should not show up in docker ps

Alexander Larsson 006e2a600c ApplyLayer() use RemoveAll to handle removing directories 
rmTargetPath can be a directory, so we have to use RemoveAll() or we
will fail to whiteout non-empty directories.
