-# go-winio
-
-This repository contains utilities for efficiently performing Win32 IO operations in
-Go. Currently, this is focused on accessing named pipes and other file handles, and
-for using named pipes as a net transport.
-
-This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
-to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
-newer operating systems. This is similar to the implementation of network sockets in Go's net
-package.
-

-[opencode@microsoft.com](mailto:opencode@microsoft.com) with any additional
-questions or comments.
-
-Thanks to natefinch for the inspiration for this library. See https://github.com/natefinch/npipe

-
-This is a Go port of the exponential backoff algorithm from [Google's HTTP Client Library for Java][google-http-java-client].
-
-[Exponential backoff][exponential backoff wiki]
-is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
-in order to gradually find an acceptable rate.
-The retries exponentially increase and stop increasing when a certain threshold is met.
-
-## Usage
-
-See https://godoc.org/github.com/cenkalti/backoff#pkg-examples
-
-## Contributing
-
-* I would like to keep this library as small as possible.
-* Please don't send a PR without opening an issue and discussing it first.
-* If proposed change is not a common use case, I will probably not accept it.

-ExponentialBackOff is a backoff implementation that increases the backoff
-period for each retry attempt using a randomization function that grows exponentially.
-
-NextBackOff() is calculated using the following formula:
-
- randomized interval =
-     RetryInterval * (random value in range [1 - RandomizationFactor, 1 + RandomizationFactor])
-
-In other words NextBackOff() will range between the randomization factor
-percentage below and above the retry interval.
-
-For example, given the following parameters:
-
- RetryInterval = 2
- RandomizationFactor = 0.5
- Multiplier = 2
-
-the actual backoff period used in the next retry attempt will range between 1 and 3 seconds,
-multiplied by the exponential, that is, between 2 and 6 seconds.
-
-Note: MaxInterval caps the RetryInterval and not the randomized interval.
-
-If the time elapsed since an ExponentialBackOff instance is created goes past the
-MaxElapsedTime, then the method NextBackOff() starts returning backoff.Stop.
-
-The elapsed time can be reset by calling Reset().
-
-Example: Given the following default arguments, for 10 tries the sequence will be,
-and assuming we go over the MaxElapsedTime on the 10th try:

-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing

-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its

-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,

-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-# Working on the Engine API
-
-The Engine API is an HTTP API used by the command-line client to communicate with the daemon. It can also be used by third-party software to control the daemon.
-
-It consists of various components in this repository:
-
-- `api/swagger.yaml` A Swagger definition of the API.
-- `api/types/` Types shared by both the client and server, representing various objects, options, responses, etc. Most are written manually, but some are automatically generated from the Swagger definition. See [#27919](https://github.com/docker/docker/issues/27919) for progress on this.
-- `cli/` The command-line client.
-- `client/` The Go client used by the command-line client. It can also be used by third-party Go programs.
-- `daemon/` The daemon, which serves the API.
-
-## Swagger definition
-
-The API is defined by the [Swagger](http://swagger.io/specification/) definition in `api/swagger.yaml`. This definition can be used to:
-
-1. Automatically generate documentation.
-2. Automatically generate the Go server and client. (A work-in-progress.)
-3. Provide a machine readable version of the API for introspecting what it can do, automatically generating clients for other languages, etc.
-
-## Updating the API documentation
-
-The API documentation is generated entirely from `api/swagger.yaml`. If you make updates to the API, edit this file to represent the change in the documentation.
-
-The file is split into two main sections:
-
-- `definitions`, which defines re-usable objects used in requests and responses
-- `paths`, which defines the API endpoints (and some inline objects which don't need to be reusable)
-
-To make an edit, first look for the endpoint you want to edit under `paths`, then make the required edits. Endpoints may reference reusable objects with `$ref`, which can be found in the `definitions` section.
-
-There is hopefully enough example material in the file for you to copy a similar pattern from elsewhere in the file (e.g. adding new fields or endpoints), but for the full reference, see the [Swagger specification](https://github.com/docker/docker/issues/27919).
-
-`swagger.yaml` is validated by `hack/validate/swagger` to ensure it is a valid Swagger definition. This is useful when making edits to ensure you are doing the right thing.
-
-## Viewing the API documentation
-
-When you make edits to `swagger.yaml`, you may want to check the generated API documentation to ensure it renders correctly.
-
