* Caching the parent id of the current process
In certain scenarios, like a domain joined machine with an executionpolicy set via GPO, a lot of checks are done for the ExecutionPolicy, and this is in the hot path.
* Caching HasGPScriptParent.
It is expensive to determine if a script was run as a result of applying a group policy. This does not change during the lifetime of a process.
This only affect the scenario when an execution policy has been set by a group policy.

string. If the string was a uri with spaces, ToString() doesn't return the escaped version. The AbsoluteUri property
should be used instead which returns an escaped absolute uri (if valid).
Also renamed TestModuleManfest.ps1 to TestModuleManifest.Tests.ps1 so that it gets picked up correctly as Pester test.
Since HelpInfoUri is just a string, ensure it is a valid absolute uri and escaped correctly whereas before it was just
an opaque string that wasn't validated.
Rather than relying on case-insensitive string compares of source and destination paths, use operating system calls to determine whether two paths refer to the same file. This solves not only the case-insensitivity issue but also allows the cmdlet to operate properly if the destination is a hard or symbolic link to the source.
The Windows side is implemented in C#. The Unix side is implemented partially in native code.
This makes it possibe to write for example
[ValidatePattern('[A-Z]:', ErrorMessage='The Drive should be specified as a single letter followed by a colon, for example "D:"')]
[string] $Drive,
The element being validated is also passed, so {0} can be used in the custom error message
This change moves powershell to .NET Core 2.0. Major changes are:
1. PowerShell assemblies are now targeting `netcoreapp2.0`. We are using `microsoft.netcore.app-2.0.0-preview1-001913-00`, which is from dotnet-core build 4/4/17. We cannot target `netstandard2.0` because the packages `System.Reflection.Emit` and `System.Reflection.Emit.Lightweight`, which are needed for powershell class, cannot be referenced when targeting `netstandard2.0`.
2. Refactor code to remove most CLR stub types and extension types.
3. Update build scripts to enable CI builds. The `-cache` section is specified to depend on `appveyor.yml`, so the cache will be invalidated if `appveyor.yml` is changed.
4. Ship `netcoreapp` reference assemblies with powershell to fix the issues in `Add-Type` (#2764). By default `Add-Type` will reference all those reference assemblies when compiling C# code. If `-ReferenceAssembly` is specified, then we search reference assemblies first, then the framework runtime assemblies, and lastly the loaded assemblies (possibly a third-party one that was already loaded).
5. `dotnet publish` generates executable on Unix platforms, but doesn't set "x" permission and thus it cannot execute. Currently, the "x" permission is set in the build script, `dotnet/cli` issue [#6286](https://github.com/dotnet/cli/issues/6286) is tracking this.
6. Replace the use of some APIs with the ones that take `SecureString`.
7. osx.10.12 is required to update to `netcoreapp2.0` because `dotnet-cli` 2.0.0-preview only works on osx.10.12.
8. Add dependency to `System.ValueTuple` to work around a ambiguous type identity issue in coreclr. The issue is tracked by `dotnet/corefx` [#17797](https://github.com/dotnet/corefx/issues/17797). When moving to newer version of `netcoreapp2.0`, we need to verify if this dependency is still needed.
Now `New-Item` can create a file symlink to a file target or to a non-existent target. It can also create a directory symlink to a directory target on Windows.
- Fix incorrect handling of 'GetCurrentProcess()' API return value in 'IsWow64()' function (MainEntry.cpp)
- Remove unused INVALID_HANDLE_VALUE field from 'ProcessNativeMethods' class (Process.cs)
There are cases like using PowerShell via Puppet where the account being
used does not have a home directory. Updated PowerShell to use a process
specific temporary directory if HOME, CONFIG, CACHE, and DATA directories
are not available. Temporary directory is removed when last runspace
is disposed.
Based on the conclusion in discussion #3248, this PR fix "OEM" and "Default" encoding in powershell.
1. OEM -- We need an internal fix because .Net Core has no "OEM" encoding.
The fix gives the following PowerShell Core behavior on "OEM" encoding:
- on Windows - as Windows PowerShell based on GetOEMCP() and legacy encodings (System.Text.Encoding.CodePages)
- on Unix - the same as default encoding in PowerShell Core
2. Default -- We need internal fix because CoreFX `Encoding.default` for all platforms is UTF8.
Until we complete the `Encoding RFC` we should restore behavior as in Windows PowerShell.
The fix gives the following PowerShell Core behavior on "Default" encoding:
- on Windows - as Windows PowerShell based on GetACP() and legacy encodings (System.Text.Encoding.CodePages)
- on Unix - UTF-8 without BOM (We are expecting that the same will be [in CoreFX](https://github.com/dotnet/coreclr/issues/10643))
* Help was incorrectly returning multiple instances of the same help file if it existed under a culture path and the parent was in the search path as well
* updated test to use generated help file rather than an actual one
* Fixed test to have module in $pshome path and casing of en-US culture
- FullCLR build is disabled in this change.
- FullCLR build related functionalities in `build.psm1` and `AppVeyor.psm1` are disabled. They are not cleaned up from `build.psm1` and `AppVeyor.psm1` yet. We need to adopt .NET Core 2.0 to verify the portable module concept, and if that works well, we will remove the Windows PowerShell source code and clean up our scripts.
- `dnxcore50` and `portable-net5+win8` target framework monikers are removed.
- Dependency on `Microsoft.NETCore.Portable.Compatibility` is removed. It's not necessary, but it may come back when we work on supporting the `portable module`. Its necessity can be reviewed at that time.
- I didn't spend the time to try building powershell in Visual Studio 2017. We should have a separate issue for that. It's tracked by #3400
The `TypeCatalogParser` project is replaced by a MSBuild target to gather the dependency information.
Due to .NET Core SDK issue [#1021](https://github.com/dotnet/sdk/issues/1021), our meta-package project `Microsoft.PowerShell.SDK` starts to generate an empty assembly during the build and that results in an empty assembly `Microsoft.PowerShell.SDK.dll` appear in `publish` folder and in `.deps.json` file. We cannot simply remove the assembly because it's now part of the TPA, and removing it will cause powershell to crash at startup. We have to live with this empty assembly until that .NET Core SDK issue is fixed. It's tracked by #3401.
Our assembly cache contains assemblies that are explicitly loaded by powershell egine, such as via module loading or the assembly entries from InitialSessionState. We should search it before searching all loaded assemblies to give preference to resolve a type against the assemblies contained in the cache, so that in case there is a conflict, we might have a preferred assembly to use for a type resolution.
Changes:
- Search from context.AssemblyCache.Values before search from all loaded assemblies.
- Skip assemblies that we already searched and found no matching type.
- Skip checking PS types kept in the scope and type accelerators when it's not necessary.

XDG profile directory creation can fail for accounts that do not have home directories.
The module analysis was trying to persist it's cache in an XDG profile directory.
The cache is less critical than it once was, so it's reasonable to not cache if there is no good place to do so.
Fixes#3011
Changed hard coded Windows directory separator and resolved path so the slashes are correct.
Throw if resolving file path returns more than one result
Fixes#2610
These changes provide the ability to debug remote running scripts started with the Invoke-Command cmdlet. The design is event based and provides new public events that allow subscribers to be notified when an Invoke-Command remote session is ready for debugging. Since Invoke-Command allows running scripts on multiple targets at once (fan-out) the notification event is raised for each remote session as it becomes ready for debugging. The subscriber to these events will be a script debugger implementation (such as PowerShell console, ISE, or VSCode) and will handle all debugging details such as simultaneously debugging multiple remote sessions at once in separate windows.
But these changes also include an internal implementation which is used by default if host debuggers don't want to handle the debugging details. This internal implementation is what PowerShell console, ISE uses so they can have this new behavior without having to modify their debugger implementations. The internal implementation serializes each remote session of Invoke-Command so that they can be debugged one at a time. The remote session debugger is "pushed" onto the internal debugger stack so that debugging transitions to the remote session. Existing debugging commands work so that the "quit" debugging command will stop the current remote session script from running and allow the next remote session to be debugged. Similarly the "continue" debugging command allows the script to continue running outside step mode and again go to the next remote session for debugging. The "stepout" debugging command steps out of all Invoke-Command remote sessions and lets the script continue to run for each remote session in parallel as they are normally run.
The purpose of Invoke-Command step-in remote debugging is allow seamless debugging of a local script that calls Invoke-Command on remote targets. But there is also a new Invoke-Command "-RemoteDebug" parameter that lets you Invoke-Command on the command line and have it drop directly into the debugger.
An example from the PowerShell command line looks like this:
```
PS C:\> C:\TestICM.ps1
Entering debug mode. Use h or ? for help.
Hit Command breakpoint on 'Invoke-Command'
At C:\TestICM.ps1:2 char:1
+ Invoke-Command -cn $computerName,paulhig-3 -File c:\LinuxScript.ps1
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[DBG]: PS C:\>> list
1: $computerName = "localhost"
2:* Invoke-Command -cn $computerName,paulhig-3 -File c:\LinuxScript.ps1
3: "Test Complete!"
[DBG]: PS C:\>> stepin
At line:1 char:1
+ Write-Output "Running script on Linux!"
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[paulhig-3]:[DBG]: [Process:14072]: [Runspace5]: PS C:\Users\paulhi\Documents>
```
Notice that the debugger "stepin" command transitioned from local script debugging to debugging the remote session on computer "paulhig-3", as can be seen by the change in the debugger prompt.
You can also do this from the command line to drop directly into the debugger
```
Invoke-Command -cn localhost -Script $scriptblock -RemoteDebug
```
These changes also remove an old behavior that was incompatible with this new step-in feature. Previously if a remote session running script hit a break point it would stop in the debugger and go to the "disconnected session" state. This was to allow the user to reconnect using Enter-PSSession and then interactively debug the remote session script. This behavior has been removed and now the user needs to attach a debugger using the newer Debug-Runspace cmdlet.
* Implement -version parameter in console host (address part of https://github.com/PowerShell/PowerShell/issues/1084)
This does not support providing a specific version to run, but
like most other *nix commands, -version will now return the version
of the PowerShell Engine. 'powershell' is prepended to the output to
match other *nix commands. We are using gitcommitid which includes more
info about the build.
When a TypeTable is created it includes the types from type files provided along with references to the type files. When the InitialSessionState (ISS) object processes these types it reads the type files again and ends up with duplicate type entries. PowerShell V5.1 ISS type processing was re-written to improve performance and no longer removes duplicate types, so that this scenario (runspace ISS reuse) results in errors causing a regression.
The fix is to copy only type data when a TypeTable is passed to the ISS.
