This commit adds a transfer manager which deduplicates and schedules transfers, and also an upload manager and download manager that build on top of the transfer manager to provide high-level interfaces for uploads and downloads. The push and pull code is modified to use these building blocks. Some benefits of the changes: - Simplification of push/pull code - Pushes can upload layers concurrently - Failed downloads and uploads are retried after backoff delays - Cancellation is supported, but individual transfers will only be cancelled if all pushes or pulls using them are cancelled. - The distribution code is decoupled from Docker Engine packages and API conventions (i.e. streamformatter), which will make it easier to split out. This commit also includes unit tests for the new distribution/xfer package. The tests cover 87.8% of the statements in the package. Signed-off-by: Aaron Lehmann <aaron.lehmann@docker.com> |

pkg/ is a collection of utility packages used by the Docker project without being specific to its internals.
Utility packages are kept separate from the docker core codebase to keep it as small and concise as possible. If some utilities grow larger and their APIs stabilize, they may be moved to their own repository under the Docker organization, to facilitate re-use by other projects. However that is not the priority.
The directory pkg
is named after the same directory in the camlistore project. Since Brad is a core
Go maintainer, we thought it made sense to copy his methods for organizing Go code :) Thanks Brad!
Because utility packages are small and neatly separated from the rest of the codebase, they are a good place to start for aspiring maintainers and contributors. Get in touch if you want to help maintain them!
