go.mod: Bump go-winio to v0.6.0
Some minor improvements, but biggest for here is ErrPipeListenerClosed is no longer an errors.New where the string matches the text of the now exported net.ErrClosed in the stdlib, but is just assigned to net.ErrClosed directly. This should allow us to get rid of the string check for "use of closed network connection" here now.. Signed-off-by: Daniel Canter <dcanter@microsoft.com>

For details, visit [Microsoft CLA](https://cla.microsoft.com).

When you submit a pull request, a CLA-bot will automatically determine whether you need to provide a CLA and decorate the PR
|

appropriately (e.g., label, comment). Simply follow the instructions provided by the bot. You will only need to do this once across all repos using our CLA.

You will only need to do this once across all repos using our CLA.
|
||||
|
||||
We also require that contributors sign their commits using git commit -s or git commit --signoff to certify they either authored the work themselves
|
||||
or otherwise have permission to use it in this project. Please see https://developercertificate.org/ for more info, as well as to make sure that you can
|
||||
attest to the rules listed. Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
|
||||
Additionally, the pull request pipeline requires the following steps to be performed before
|
||||
mergining.
|
||||
|
||||
### Code Sign-Off
|
||||
|
||||
We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
|
||||
to certify they either authored the work themselves or otherwise have permission to use it in this project.
|
||||
|
||||
A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
|
||||
|
||||
Please see [the developer certificate](https://developercertificate.org) for more info,
|
||||
as well as to make sure that you can attest to the rules listed.
|
||||
Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
|
||||
|
||||
### Linting
|
||||
|
||||
Code must pass a linting stage, which uses [`golangci-lint`][lint].
|
||||
The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
|
||||
automatically with VSCode by adding the following to your workspace or folder settings:
|
||||
|
||||
```json
|
||||
"go.lintTool": "golangci-lint",
|
||||
"go.lintOnSave": "package",
|
||||
```
|
||||
|
||||
Additional editor [integrations options are also available][lint-ide].
|
||||
|
||||
Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
|
||||
|
||||
```shell
|
||||
# use . or specify a path to only lint a package
|
||||
# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
|
||||
> golangci-lint run ./...
|
||||
```
|
||||
|
||||
### Go Generate
|
||||
|
||||
The pipeline checks that auto-generated code, via `go generate`, are up to date.
|
||||
|
||||
This can be done for the entire repo:
|
||||
|
||||
```shell
|
||||
> go generate ./...
|
||||
```

|

## Security
|
||||
|
||||
Microsoft takes the security of our software products and services seriously, which includes all source code repositories managed through our GitHub organizations, which include [Microsoft](https://github.com/Microsoft), [Azure](https://github.com/Azure), [DotNet](https://github.com/dotnet), [AspNet](https://github.com/aspnet), [Xamarin](https://github.com/xamarin), and [our GitHub organizations](https://opensource.microsoft.com/).
|
||||
|
||||
If you believe you have found a security vulnerability in any Microsoft-owned repository that meets [Microsoft's definition of a security vulnerability](https://aka.ms/opensource/security/definition), please report it to us as described below.
|
||||
|
||||
## Reporting Security Issues
|
||||
|
||||
**Please do not report security vulnerabilities through public GitHub issues.**
|
||||
|
||||
Instead, please report them to the Microsoft Security Response Center (MSRC) at [https://msrc.microsoft.com/create-report](https://aka.ms/opensource/security/create-report).
|
||||
|
||||
If you prefer to submit without logging in, send email to [secure@microsoft.com](mailto:secure@microsoft.com). If possible, encrypt your message with our PGP key; please download it from the [Microsoft Security Response Center PGP Key page](https://aka.ms/opensource/security/pgpkey).
|
||||
|
||||
You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Additional information can be found at [microsoft.com/msrc](https://aka.ms/opensource/security/msrc).
|
||||
|
||||
Please include the requested information listed below (as much as you can provide) to help us better understand the nature and scope of the possible issue:
|
||||
|
||||
* Type of issue (e.g. buffer overflow, SQL injection, cross-site scripting, etc.)
|
||||
* Full paths of source file(s) related to the manifestation of the issue
|
||||
* The location of the affected source code (tag/branch/commit or direct URL)
|
||||
* Any special configuration required to reproduce the issue
|
||||
* Step-by-step instructions to reproduce the issue
|
||||
* Proof-of-concept or exploit code (if possible)
|
||||
* Impact of the issue, including how an attacker might exploit the issue
|
||||
|
||||
This information will help us triage your report more quickly.
|
||||
|
||||
If you are reporting for a bug bounty, more complete reports can contribute to a higher bounty award. Please visit our [Microsoft Bug Bounty Program](https://aka.ms/opensource/security/bounty) page for more details about our active programs.
|
||||
|
||||
## Preferred Languages
|
||||
|
||||
We prefer all communications to be in English.
|
||||
|
||||
## Policy
|
||||
|
||||
Microsoft follows the principle of [Coordinated Vulnerability Disclosure](https://aka.ms/opensource/security/cvd).
