Recent changes to devmapper broke the implicit requirement that UdevWait be called after every call to task.setCookie. Failure to do so results in leaks of semaphores in the LVM code, eventually leading to semaphore exhaustion. Previously this was handled by calling UdevWait in a ubiquitous defer function. While there was initially some concern with deferring the UdevWait function would cause some amount of race possibiliy, the fact that we never return the cookie value or any value used to find it, makes that possibility seem unlikely, so lets go back to that method Signed-off-by: Neil Horman <nhorman@tuxdriver.com> (cherry picked from commit 23dcfec1404411489e23fb9b76fc7096db139d04) Signed-off-by: Victor Vieux <victorvieux@gmail.com>
Docker CE
This repository hosts open source components of Docker Community Edition
(CE) products. The master branch serves to unify the upstream components
on a regular basis. Long-lived release branches host the code that goes
into a product version for the lifetime of the product.
This repository is solely maintained by Docker, Inc.
Unifying upstream sources
The master branch is a combination of components adapted from
different upstream git repos into a unified directory structure using the
moby-components
tool.
You can view the upstream git repos in the components.conf file. Each component is isolated into its own directory under the components directory.
The tool will import each component git history within the appropriate path.
For example, this shows a commit
is imported into the component engine from
moby/moby@a27b4b8
into the components/engine directory.

Updates to master branch
Main development of new features should be directed towards the upstream
git repos. The master branch of this repo will periodically pull in new
changes from upstream to provide a point for integration.
Branching for release
When a release is started for Docker CE, a new branch will be created
from master. Branch names will be YY.MM to represent the time-based
release version of the product, e.g. 17.06.
Adding fixes to release branch
Note: every commit of a fix should affect files only within one component directory.
Fix available upstream
A PR cherry-picking the necessary commits should be created against the release branch. If the the cherry-pick cannot be applied cleanly, the logic of the fix should be ported manually.
No fix yet
First create the PR with the fix for the release branch. Once the fix has been merged, be sure to port the fix to the respective upstream git repo.
Release tags
There will be a git tag for each release candidate (RC) and general availablilty (GA) release. The tag will only point to commits on release branches.
