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
* Add autoload for TestHelpers.psm1
Test.Helpers.psm1 was renamed to TestHelpers.psm1
* Resolve conflit and rebase Add autoload for TestLanguage.psm1
* Remove unneeded comments from PSD1 files
* Rename test modules
Remove approved verbs (Get-Verb) from module names.
* Enhance ShouldBeErrorId to output exception into pipeline for later analysis
* Remove unneeded comments
* Resolve merge conflict
when automating test execution, some environments don't have a tty which causes
the tests to fail. df is just as good a test as stty as it is also guaranteed to be
present. This change also allows the tests to be run on OSX
This change enables globbing (wildcard expansion) against the file system for native commands like '/bin/ls'. The expansion is only done in the file system. In non-filesystem drives expansion is not done and the pattern is returned unchanged.
Limitations of the fix:
Currently quoting is not honored so for a command like /bin/ls "*.txt", wildcard expansion will still be done. Adding support for bare word detection will come in a future PR. Use --% to suppress wildcard expansion e.g. git add --% *
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.

1. Add autoload for test modules
2. Move TestHostCS.psm1 to 'test\tools\Modules\' folder
3. Remove explicit load TestHostCS.psm1 from test files
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.
* corrected use of PSModulePath casing to be consistent with Windows PowerShell
addresses #3227
* addressing review feedback
make "PSModulePath" into const
fixed some test workarounds due to failures for external reasons that wasn't meant to be checked in
* addressing review feedback

* 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.
* Remove async tests for parser
this is a fix for https://github.com/PowerShell/PowerShell/issues/3069
This removes an attempt to work-around the issue of tests hanging on Travis-CI.
* remove unneeded finally block
* Improve console cmdlets tests
Main improvements refer to tests of the Write-Host cmdlet.
Original tests:
1. Slow because run external processes
2. Don't test colors and -NoNewLine in fact.
1. The original tests is preserved (deleted one as redundant) but marked
by 'Slow' tag. They is preserved because they actually check the output
on the work, not a test console.
2. Add negative color tests. (Code cover grow!)
3. Add tests based on TestHostCS. This test host has been refined so we
can see colors and a new line in output.
4. Add minor fixes for test modules loads.
Also I add support for Information stream. I originally planned to use
it but not actually used. However, I have left this as a useful addition
for future tests.
I wonder that a Write-Host console output is duplicated in Information
Stream - Is it by design? I left a debug print on this matter in the
test code.
* Fix after code review
* Corrections after code review
Suppress import-module warnings
Rename Describes
Add "-Object" test
Add Stream.Information tests with TestHostCS
* Add checks for Streams.Information and add comments
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'
* Stifle progress output in build.psm1 for some operations
Modify test failure presentation to use platform available XML methods
* Add timeout support for returning runtime parsing errors
Some of the language/parser tests have been hanging in a non-reproducable manner which
causes the CI system to invalidate the entire run. This change adds support for timeout
which will fail a test if it runs to long, rather than invalidate the entire run.
current behavior is still supported, and is not done in a new session:
PS> get-runtimeerror -src '1/'
At line:1 char:3
+ 1/
+ ~
You must provide a value expression following the '/' operator.
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : ExpectedValueExpression
Adding a timeout will do the operation in a async powershell session
PS> get-runtimeerror -src '1/' -timeout 5
You must provide a value expression following the '/' operator.
+ CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : ExpectedValueExpression
If the operation takes longer than the supplied timeout, a timeout error will be returned
PS> get-runtimeerror -src 'start-sleep 6' -timeout 2
get-runtimeerror : Operation Timed Out ('start-sleep 6')
At line:1 char:1
+ get-runtimeerror -src 'start-sleep 6' -timeout 2
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [Write-Error], WriteErrorException
+ FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException,Get-RuntimeError
* Modify native linux command tests to skip on Windows and pending on Mac
* remove verbose and progress output from help tests
* Be sure that Feature Counter tests only run on Windows
Also, only call add-type in CounterTestHelperFunctions.ps1 if we're going to actually run the tests
* do not run any get-computerinfo tests on non-windows systems
* suppress progress output from PowerShell Get tests
* remove -quiet from API and CRON Builds
Travis watches output from the build to ensure that it hasn't hung
we need to find a balance between too much output and not enough output.
A run which has too much output is killed because it looks like an error loop
A run which has too little output is killed because it looks like a hang
* Remove commented line in Import-Counter.Tests.ps1
Remove extraneous extra line in PowerShellGet.Tests.ps1
* Change `-as "type"` to `-as [type]` in build.psm1
Alter timeout to 10 seconds to be improve chances of not timing out for runtime parser checks
improve logic for counter tests to also skip for IoT
* use the existing function of SkipCounterTests rather than duplicate the logic in import-counter.tests.ps1
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).
Type completion would behave strangely when there were multiple aliases for a given type (currently only possible with type accelerators).
The fix is to only select the accelerator that matches what the user typed.
Closes#2295
* Refactor 'FindMatchingHandler' to get rid of recursion
Search state can be saved and used throughout the searching process without the recursion.
* Rank the exception types based on how specific they are
* Refactor code to find handler based on the rank of given handlers
When a PS class is defined in a module and the module gets reloaded, the class would still use the SessionState from the old module for execution, and thus it doesn't reflect changes to the module state during the reload. This fix is to make sure we always use the current EngineSessionState for PS class execution.
