This project welcomes contributions and suggestions.
Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that
you have the right to, and actually do, grant us the rights to use your contribution.
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.
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.
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 ./...
```

<!-- BEGIN MICROSOFT SECURITY.MD V0.0.7 BLOCK -->
## 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).

// This package provides utilities for efficiently performing Win32 IO operations in Go.
// Currently, this package is provides support for genreal IO and management of
// - named pipes
// - files
// - [Hyper-V sockets]
//
// This code is similar to Go's [net] package, and uses IO completion ports to avoid
// blocking IO on system threads, allowing Go to reuse the thread to schedule other goroutines.
//
// This limits support to Windows Vista and newer operating systems.
//
// Additionally, this package provides support for:
// - creating and managing GUIDs
// - writing to [ETW]
// - opening and manageing VHDs
// - parsing [Windows Image files]
// - auto-generating Win32 API code

// We use the Windows API GetFinalPathNameByHandle to handle path resolution. GetFinalPathNameByHandle
// returns a resolved path name for a file or directory. The returned path can be in several different
// formats, based on the flags passed. There are several goals behind the design here:
// - Do as little manual path manipulation as possible. Since Windows path formatting can be quite
// complex, we try to just let the Windows APIs handle that for us.
// - Retain as much compatibility with existing Go path functions as we can. In particular, we try to
// ensure paths returned from resolvePath can be passed to EvalSymlinks.
//
// First, we query for the VOLUME_NAME_GUID path of the file. This will return a path in the form
// "\\?\Volume{8a25748f-cf34-4ac6-9ee2-c89400e886db}\dir\file.txt". If the path is a UNC share
// (e.g. "\\server\share\dir\file.txt"), then the VOLUME_NAME_GUID query will fail with ERROR_PATH_NOT_FOUND.
// In this case, we will next try a VOLUME_NAME_DOS query. This query will return a path for a UNC share
// in the form "\\?\UNC\server\share\dir\file.txt". This path will work with most functions, but EvalSymlinks
// fails on it. Therefore, we rewrite the path to the form "\\server\share\dir\file.txt" before returning it.
// This path rewrite may not be valid in all cases (see the notes in the next paragraph), but those should
// be very rare edge cases, and this case wouldn't have worked with EvalSymlinks anyways.
//
// The "\\?\" prefix indicates that no path parsing or normalization should be performed by Windows.
// Instead the path is passed directly to the object manager. The lack of parsing means that "." and ".." are
// interpreted literally and "\"" must be used as a path separator. Additionally, because normalization is
// not done, certain paths can only be represented in this format. For instance, "\\?\C:\foo." (with a trailing .)
// cannot be written as "C:\foo.", because path normalization will remove the trailing ".".
//
// FILE_NAME_NORMALIZED can fail on some UNC paths based on access restrictions.
// Attempt to query with FILE_NAME_NORMALIZED, and then fall back on FILE_NAME_OPENED if access is denied.
//
// Querying for VOLUME_NAME_DOS first instead of VOLUME_NAME_GUID would yield a "nicer looking" path in some cases.
// For instance, it could return "\\?\C:\dir\file.txt" instead of "\\?\Volume{8a25748f-cf34-4ac6-9ee2-c89400e886db}\dir\file.txt".
// However, we query for VOLUME_NAME_GUID first for two reasons:
// - The volume GUID path is more stable. A volume's mount point can change when it is remounted, but its
// volume GUID should not change.
// - If the volume is mounted at a non-drive letter path (e.g. mounted to "C:\mnt"), then VOLUME_NAME_DOS
// will return the mount path. EvalSymlinks fails on a path like this due to a bug.

// Stringer is a tool to automate the creation of methods that satisfy the fmt.Stringer
// interface. Given the name of a (signed or unsigned) integer type T that has constants
// defined, stringer will create a new self-contained Go source file implementing
//
// func (t T) String() string
//
// The file is created in the same package and directory as the package that defines T.
// It has helpful defaults designed for use with go generate.
//
// Stringer works best with constants that are consecutive values such as created using iota,
// but creates good code regardless. In the future it might also provide custom support for
// constant sets that are bit patterns.
//
// For example, given this snippet,
//
// package painkiller
//
// type Pill int
//
// const (
// Placebo Pill = iota
// Aspirin
// Ibuprofen
// Paracetamol
// Acetaminophen = Paracetamol
// )
//
// running this command
//
// stringer -type=Pill
//
// in the same directory will create the file pill_string.go, in package painkiller,
// containing a definition of
//
// func (Pill) String() string
//
// That method will translate the value of a Pill constant to the string representation
// of the respective constant name, so that the call fmt.Print(painkiller.Aspirin) will
// print the string "Aspirin".
//
// Typically this process would be run using go generate, like this:
//
// //go:generate stringer -type=Pill
//
// If multiple constants have the same value, the lexically first matching name will
// be used (in the example, Acetaminophen will print as "Paracetamol").
//
// With no arguments, it processes the package in the current directory.
// Otherwise, the arguments must name a single directory holding a Go package
// or a set of Go source files that represent a single Go package.
//
// The -type flag accepts a comma-separated list of types so a single run can
// generate methods for multiple types. The default output file is t_string.go,
// where t is the lower-cased name of the first type listed. It can be overridden
// with the -output flag.
//
// The -linecomment flag tells stringer to generate the text of any line comment, trimmed
// of leading spaces, instead of the constant name. For instance, if the constants above had a
// Pill prefix, one could write
//
// PillAspirin // Aspirin
//
// to suppress it in the output.

//
// Although it might seem convenient for this package to live alongside
// go/types in the standard library, this would cause version skew
// problems for developer tools that use it, since they must be able to
// consume the outputs of the gc compiler both before and after a Go
// update such as from Go 1.7 to Go 1.8. Because this package lives in
// golang.org/x/tools, sites can update their version of this repo some
// time before the Go 1.8 release and rebuild and redeploy their
// developer tools, which will then be able to consume both Go 1.7 and
// Go 1.8 export data files, so they will work before and after the
// Go update. (See discussion at https://golang.org/issue/15651.)
