Creates a `fixedBuffer` type that is used to encapsulate functionality for reading/writing from the underlying byte slices. Uses lazily-loaded set of sync.Pools for storing buffers that are no longer needed so they can be re-used. ``` benchmark old ns/op new ns/op delta BenchmarkBytesPipeWrite-8 138469 48985 -64.62% BenchmarkBytesPipeRead-8 130922 56601 -56.77% benchmark old allocs new allocs delta BenchmarkBytesPipeWrite-8 18 8 -55.56% BenchmarkBytesPipeRead-8 0 0 +0.00% benchmark old bytes new bytes delta BenchmarkBytesPipeWrite-8 66903 1649 -97.54% BenchmarkBytesPipeRead-8 0 1 +Inf% ``` Signed-off-by: Brian Goff <cpuguy83@gmail.com> Upstream-commit: 9a25b1d942da88439ec04797ff6f1c33c3b5562d Component: engine
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!
