When InitialSessionState initializes it tries to SetLocation to current working directory,
but if the directory name contains PowerShell wildcard characters, it fails and reverts
to $PSHOME.
The change affects Set-Location in that if the path exists (even if containing wildcard characters), just use it. It is a breaking change.
This unifies file encoding across the inbox cmdlets to be UTF-8 without a BOM for all platforms. This is a breaking change as cmdlets on windows have a number of different encodings. This supports better interoperability with tradition Linux shells as we are using the same encoding.
Validate that files are created with UTF-8 encoding without BOM
Update tests to validate Encoding parameter to new type and create new tests for
parameter type validation.
[Breaking Change] The '-Encoding Byte' has been removed from the filesystem provider cmdlets. A new parameter '-AsByteStream' is now added to indicate that a byte stream is required as input, or output will be a stream of bytes.
Code guarded by the following defines is ancient and has never been
used, so removing.

Make `System.Management.Automation references` to package `System.Security.Permissions`, which brings back `SecurityZone` and `System.Security.Policy.Zone`.
On CoreFx, UseShellExecute for Process start is false by default to be cross platform compatible.
In the case of a folder, Process.Start() returns Access Denied as it's not an executable.
On Windows, we can use the ShellExecute path to have explorer open the folder. On Unix, we use `xdg-open` and `open` for Linux and macOS respectively.
- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'ForEach-Object' (alias is '%' or 'foreach')
- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'Where-Object' (alias is '?' or 'where')
- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'Select-Object' (alias is 'select')
- Fix PSScriptAnalyzer warnings of type PSPossibleIncorrectComparisonWithNull. Essentially, $null has to be on the left-hand side when using it for comparison.
- A Test in ParameterBinding.Tests.ps1 needed adapting as this test used to rely on the wrong null comparison
- Replace a subset of tests of kind '($object -eq $null) | Should Be $true' with '$object | Should Be $null'
Add the dynamic parameter `-FollowSymlink` to `Get-ChildItem`.
Add a mechanism for tracking visited directories.
Add native code to get device/inode information on Unix/Windows.
Add warning when refusing to enter an already-visited directory.
Added try/catch within the enumeration loop to allow the enumeration to continue after encountering an error such as an item within the directory being deleted or renamed.
To assist in testing, two new internal test hooks have been added which cause Get-ChildItem to either delete or rename a specific file (file name hard-coded) when encountered during enumeration.
Use the method NativeCommandParameterBinder.NeedQuotes, which is used by powershell native command processor, to check if quotes are needed. If yes, add quotes in the same way as our native command processor.
Also, make 'Invoke-Item' on Linux and OSX able to invoke an executable properly.
Brings the Get-ChildItem more in line with the Unix ls -r and the Windows DIR /S native commands. Like these commands, the cmdlet will display symbolic links to directories found during recursion but will not recurse into them.
Like the Unix ls command---and unlike the Windows DIR /S command--- the cmdlet will recurse into symlinks given on the command line.
* Fix Rename-Item to allow Unix globbing patterns in -Literal paths (#2799)
In the process of normalizing a relative path, PowerShell checks to see
see if the path exists, which it does by invoking
Directory.EnumerateFiles(directory, filename);
On Unix platforms, if the filename contains globbing patterns, such as [ab],
EnumerateFiles (and EnumerateDirectories) will perform the globbing. Using
globbing patterns, a file named 'file[txt].txt' is reported as not existing.
This fix changes the file-existence test on Unix to use a native function
instead of either of the Directory.EnumerateXXX functions.
* Fix for AppVeyor failure
* Changes per code review, and a couple of letter-casing changes.
When 'Remove-Item' is used to remove a symbolic link in Windows, only the link itself is removed. The '-Force' switch is no longer required.
If the directory pointed to by the link has child items, the cmdlet no longer prompts the user to remove the child items---those child items are not removed. The '-Recurse' switch, if given, is ignored.
This brings 'Remove-Item' more in line with the behavior of the 'rm' command on Unix.
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 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.
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))
Our private implementation of FailFast was likely introduced
when each individual application needed it's own code to
get Watson reports. The CLR takes care of this for us now,
so we don't need our implementation.
Our method CheckForSevereException was also introduced in
the early days of the CLR - the exceptions it was checking
for aren't actually raised the CLR anymore, they just FailFast.
I removed them as there is a tiny bit of overhead (in code size)
and also in the generated code, e.g. dynamic sites called the method.
Resolving #2570.
Ignore drive paths in the check. If the input is a drive path,
then "\" is passed as the path to GetDriveQualifiedPath with drive info.
Since, the path here starts with "\", treatAsRelative is set to false
which prevents further formatting of this path.
The check is only valid for PSDrives with root path equals to UNC paths or the paths
in unix.
Resolving #2206
Set-Content fails to create a file for PSDrive path, if the path root
begins with defaultPathSeperatorString (ex: UNC path and paths in Single
rooted filesystems like Unix)
This is verified to work "correctly" on Linux in that it gets the
`perror` for the last set value of errno in native code.
No extra mapping or handling needs to be done on our part.
Keeping the strerror_r implementation in the history for the valuable
implementation of config.h.in in the library.
