Based on standard practices, we need to have a copyright and license notice at the top of each source file. Removed existing copyrights and updated/added copyright notices for .h, .cpp, .cs, .ps1, and .psm1 files.
Updated module manifests for consistency to have Author = "PowerShell" and Company = "Microsoft Corporation". Removed multiple line breaks.
Separate PR coming to update contribution document for new source files: #6140
Manually reviewed each change.
Fix#6073
Underpinnings to make calling of Extension methods /Linq easier from PowerShell.
Enables the following that previously had to be done via reflection.
class M {
[int] Twice([int] $value) { return 2 * $value }
[int] DoubleSum([int[]] $values) {
return [Linq.Enumerable]::Sum($values, [M]::Twice)
}
}
Each PSMethod is created as with a unique type for the combinations of method signatures in the MethodInfos it represents.
PSMethod<T> where T is a MethodGroup<>, potentially recursive in the last template argument.
This way, we can determine by just looking at the type of a PSMethod if there exists a conversion from the PSMethod to a delegate.
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.
- Rename powershell.exe to pwsh.exe
- Fixe appveyor.psm1
- Update MSI to include 'pwsh' in path and app paths
- Revert change for hyper-v powershell direct
- Update names in packaging.psm1.
- Fix check for SxS
- Add 'ArgumentCompletionsAttribute' to support argument completion for parameters that cannot have a ValidateSetAttribute.
- Use 'ArgumentCompletionsAttribute' for the '-Format' parameter of 'Get-Date' to enable useful argument compeltions.
When handling file redirection for CommandExpression, we don't call 'DoComplete' on the underlying PipelineProcessor of the FileRedirection object, and thus the EndProcessing method is not called on Out-File, which causes different behaviors between <expr> > out.txt and <expr> | Out-File out.txt.
The fix is to make sure 'DoComplete' is called after the stream output has been written to the redirection pipe.
Also fix another issue
This PR also fixes an issue that could mess up restoring the original pipes. Here is the repro:
PS> 1 *> b.txt > a.txt; 123
Cannot perform operation because object "PipelineProcessor" has already been disposed
The root cause is that we don't always restore pipes in the correct order. Please see the code changes in Compiler.cs for more details.
Fix#4812
- 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'
Implements support for backgrounding pipelines with &. Putting & at the end of a pipeline will cause the pipeline
to be run as a PowerShell job. When a pipeline is backgrounded a job object is returned. Once the pipeline is
running as a job, all of the normal job cmdlets can be used to manage the job. Variables (ignoring process-specific
variables) used in the pipeline are automatically copied to the job so
copy $foo $bar &
just works. The job is also run in the current directory instead of the user's home directory as is the case with Start-Job.Implement

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.
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.
* Fix GetType() bad pattern and related issues in tests
$var.GetType() can raise an exception in tests so we should check $var
before make the call. A large part of the tests does not make this
check.
I start with searching ".GetType()" but discovered many related issues
in tests (reduntant and unneeded tests, "throw" bad pattens, bugs,
formattings (sorry!) and so on) - I had to fix them too.
* Fix after code review
* Second wave of migration GetType() -> BeOfType
Removed 'GetType().Name' patterns.
Interactive hosts expect an `IncompleteParseException` to signal that more input is expected.
When detecting errors, the parser can report 2 positions:
* where the error should be reported
* where the error was detected
Typically these are the same, so most error reporting methods have a single parameter.
For missing braces, the pattern is supposed to be to report the error after the opening brace, but the error is typically detected at the end of the file.
There were a few places where we were not consistent in reporting such errors, this PR corrects those places.
Native argument completers were not invoked when the argument was a single dash.
The fix is to treat unbound command parameters as command arguments for the purposes of parameter/argument completion.
* Make small optimization in parser tests
* Add Clear() for common command
Remove commands from AfterEach
* Refactoring test 'functions are resolved before cmdlets'
The tokenizer did multiple scans the script line to get tokens. Before
the fix the tokenizer on the first pass examined that string as
double-quoted (Expandable) string not as here string, figured the
average double quotation mark as a closing and then starting with the
single quotation mark continued processing the line as single-quoted
string which had no closing single quotation mark.
The fix is to stop the first scan pass after getting '=' (assume
assignment-expression '$a=' for next pass).
People use Out-Null despite much faster alternatives:
$null = Do-Stuff
[void] = Do-Stuff
Do-Stuff > $null
This change makes Out-Null work in roughly the same say as the above.
The optimization is to detect that we're calling the built-in Out-Null
cmdlet when invoking a pipeline from script (the change won't have any
effect in the PowerShell api). If we detect Out-Null, we rewrite the
pipe to look similar to `Do-Stuff > $null`.
1. Added parameterbinding test
2. Added ShouldBeErrorID function in helper file
3. Removed ShouldBeErrorID function from other test modules
4. Update New-TestHost to be able to run on full CLR
5. updated file map.json
