Cleanup #if CORECLR code

PowerShell 6.0 will be exclusively built on top of CoreCLR, so we are removing a large amount of code that's built only for FullCLR. To read more about this, check out this blog post.

6.0.0-beta.4 - 2017-07-12

Windows PowerShell backwards compatibility

In the beta.4 release, we've introduced a change to add the Windows PowerShell PSModulePath to the default PSModulePath in PowerShell Core on Windows. (#4132)

Along with the introduction of .NET Standard 2.0 in 6.0.0-beta.1 and a GAC probing fix in 6.0.0-beta.3, this change will enable a large number of your existing Windows PowerShell modules/scripts to "just work" inside of PowerShell Core on Windows. (Note: We have also fixed the CDXML modules on Windows that were regressed in 6.0.0-beta.2 as part of #4144).

So that we can further enable this backwards compatibility, we ask that you tell us more about what modules or scripts do and don't work in Issue #4062. This feedback will also help us determine if PSModulePath should include the Windows PowerShell values by default in the long run.

For more information on this, we invite you to read this blog post explaining PowerShell Core and .NET Standard in more detail.

Engine updates and fixes

  • Add Windows PowerShell PSModulePath by default on Windows. (#4132)
  • Move PowerShell to 2.0.0-preview3-25426-01 and using the .NET CLI version 2.0.0-preview2-006502. (#4144)
  • Performance improvement in PSReadline by minimizing writing ANSI escape sequences. (#4110)
  • Implement Unicode escape parsing so that users can use Unicode characters as arguments, strings or variable names. (#3958) (Thanks to @rkeithhill!)
  • Script names or full paths can have commas. (#4136) (Thanks to @TimCurwick!)
  • Added semver as a type accelerator for System.Management.Automation.SemanticVersion. (#4142) (Thanks to @oising!)
  • Close eventLogSession and EventLogReader to unlock an ETL log. (#4034) (Thanks to @iSazonov!)

General cmdlet updates and fixes

  • Move-Item cmdlet honors -Include, -Exclude, and -Filter parameters. (#3878)
  • Add a parameter to Get-ChildItem called -FollowSymlink that traverses symlinks on demand, with checks for link loops. (#4020)
  • Change New-ModuleManifest encoding to UTF8NoBOM on non-Windows platforms. (#3940)
  • Get-AuthenticodeSignature cmdlets can now get file signature timestamp. (#4061)
  • Add tab completion for Export-Counter -FileFormat parameter. (#3856)
  • Fixed Import-Module on non-Windows platforms so that users can import modules with NestedModules and RootModules. (#4010)
  • Close FileStream opened by Get-FileHash. (#4175) (Thanks to @rkeithhill!)

Remoting

  • Fixed PowerShell not responding when the SSH client abruptly terminates. (#4123)

Documentation

  • Added recommended settings for VS Code. (#4054) (Thanks to @iSazonov!)

6.0.0-beta.3 - 2017-06-20

Breaking changes

  • Remove the BuildVersion property from $PSVersionTable. This property was strongly tied to the Windows build version. Instead, we recommend that you use GitCommitId to retrieve the exact build version of PowerShell Core. (#3877) (Thanks to @iSazonov!)
  • Change positional parameter for powershell.exe from -Command to -File. This fixes the usage of #! (aka as a shebang) in PowerShell scripts that are being executed from non-PowerShell shells on non-Windows platforms. This also means that you can now do things like powershell foo.ps1 or powershell fooScript without specifying -File. However, this change now requires that you explicitly specify -c or -Command when trying to do things like powershell.exe Get-Command. (#4019)
  • Remove ClrVersion property from $PSVersionTable. (This property is largely irrelevant for .NET Core, and was only preserved in .NET Core for specific legacy purposes that are inapplicable to PowerShell.) (#4027)

Engine updates and fixes

  • Add support to probe and load assemblies from GAC on Windows platform. This means that you can now load Windows PowerShell modules with assembly dependencies which reside in the GAC. If you're interested in running your traditional Windows PowerShell scripts and cmdlets using the power of .NET Standard 2.0, try adding your Windows PowerShell module directories to your PowerShell Core $PSModulePath. (E.g. $env:PSModulePath += ';C:\Program Files\WindowsPowerShell\Modules;C:\WINDOWS\system32\WindowsPowerShell\v1.0\Modules') Even if the module isn't owned by the PowerShell Team, please tell us what works and what doesn't by leaving a comment in issue #4062! (#3981)
  • Enhance type inference in tab completion based on runtime variable values. (#2744) (Thanks to @powercode!) This enables tab completion in situations like:
$p = Get-Process
$p | Foreach-Object Prio<tab>
  • Add GitCommitId to PowerShell Core banner. Now you don't have to run $PSVersionTable as soon as you start PowerShell to get the version! (#3916) (Thanks to @iSazonov!)
  • Fix a bug in tab completion to make native.exe --<tab> call into native completer. (#3633) (Thanks to @powercode!)
  • Fix PowerShell Core to allow use of long paths that are more than 260 characters. (#3960)
  • Fix ConsoleHost to honour NoEcho on Unix platforms. (#3801)
  • Fix transcription to not stop when a Runspace is closed during the transcription. (#3896)

General cmdlet updates and fixes

  • Enable Send-MailMessage in PowerShell Core. (#3869)
  • Fix Get-Help to support case insensitive pattern matching on Unix platforms. (#3852)
  • Fix tab completion on Get-Help for about_* topics. (#4014)
  • Fix PSReadline to work in Windows Server Core container image. (#3937)
  • Fix Import-Module to honour ScriptsToProcess when -Version is specified. (#3897)
  • Strip authorization header on redirects with web cmdlets. (#3885)
  • Start-Sleep: add the alias ms to the parameter -Milliseconds. (#4039) (Thanks to @Tadas!)

Developer experience

  • Make hosting PowerShell Core in your own .NET applications much easier by refactoring PowerShell Core to use the default CoreCLR loader. (#3903)
  • Update Add-Type to support CSharpVersion7. (#3933) (Thanks to @iSazonov)

6.0.0-beta.2 - 2017-06-01

Support backgrounding of pipelines with ampersand (&) (#3360)

  • 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 standard *-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-Item $foo $bar & just works.
  • The job is also run in the current directory instead of the user's home directory.
  • For more information about PowerShell jobs, see about_Jobs.

Engine updates and fixes

  • Crossgen more of the .NET Core assemblies to improve PowerShell Core startup time. (#3787)
  • Enable comparison between a SemanticVersion instance and a Version instance that is constructed only with Major and Minor version values. This will fix some cases where PowerShell Core was failing to import older Windows PowerShell modules. (#3793) (Thanks to @mklement0!)

General cmdlet updates and fixes

  • Support Link header pagination in web cmdlets (#3828)
    • For Invoke-WebRequest, when the response includes a Link header we create a RelationLink property as a Dictionary representing the URLs and rel attributes and ensure the URLs are absolute to make it easier for the developer to use.
    • For Invoke-RestMethod, when the response includes a Link header we expose a -FollowRelLink switch to automatically follow next rel links until they no longer exist or once we hit the optional -MaximumFollowRelLink parameter value.
  • Update Get-ChildItem to be more in line with the way that the *nix ls -R and the Windows DIR /S native commands handle symbolic links to directories during a recursive search. Now, Get-ChildItem returns the symbolic links it encountered during the search, but it won't search the directories those links target. (#3780)
  • Fix Get-ChildItem to continue enumeration after throwing an error in the middle of a set of items. This fixes some issues where inaccessible directories or files would halt execution of Get-ChildItem. (#3806)
  • Fix ConvertFrom-Json to deserialize an array of strings from the pipeline that together construct a complete JSON string. This fixes some cases where newlines would break JSON parsing. (#3823)
  • Enable Get-TimeZone for macOS/Linux. (#3735)
  • Change to not expose unsupported aliases and cmdlets on macOS/Linux. (#3595) (Thanks to @iSazonov!)
  • Fix Invoke-Item to accept a file path that includes spaces on macOS/Linux. (#3850)
  • Fix an issue where PSReadline was not rendering multi-line prompts correctly on macOS/Linux. (#3867)
  • Fix an issue where PSReadline was not working on Nano Server. (#3815)

6.0.0-beta.1 - 2017-05-08

Move to .NET Core 2.0 (.NET Standard 2.0 support)

PowerShell Core has moved to using .NET Core 2.0 so that we can leverage all the benefits of .NET Standard 2.0. (#3556) To learn more about .NET Standard 2.0, there's some great starter content on Youtube, on the .NET blog, and on GitHub. We'll also have more content soon in our repository documentation (which will eventually make its way to official documentation). In a nutshell, .NET Standard 2.0 allows us to have universal, portable modules between Windows PowerShell (which uses the full .NET Framework) and PowerShell Core (which uses .NET Core). Many modules and cmdlets that didn't work in the past may now work on .NET Core, so import your favorite modules and tell us what does and doesn't work in our GitHub Issues!

Telemetry

  • For the first beta of PowerShell Core 6.0, telemetry has been to the console host to report two values (#3620):
    • the OS platform ($PSVersionTable.OSDescription)
    • the exact version of PowerShell ($PSVersionTable.GitCommitId)

If you want to opt-out of this telemetry, simply delete $PSHome\DELETE_ME_TO_DISABLE_CONSOLEHOST_TELEMETRY. Even before the first run of Powershell, deleting this file will bypass all telemetry. In the future, we plan on also enabling a configuration value for whatever is approved as part of RFC0015. We also plan on exposing this telemetry data (as well as whatever insights we leverage from the telemetry) in our community dashboard.

If you have any questions or comments about our telemetry, please file an issue.

Engine updates and fixes

  • Add support for native command globbing on Unix platforms. (#3643)
    • This means you can now use wildcards with native binaries/commands (e.g. ls *.txt).
  • Fix PowerShell Core to find help content from $PSHome instead of the Windows PowerShell base directory. (#3528)
    • This should fix issues where about_* topics couldn't be found on Unix platforms.
  • Add the OS entry to $PSVersionTable. (#3654)
  • Arrange the display of $PSVersionTable entries in the following way: (#3562) (Thanks to @iSazonov!)
    • PSVersion
    • PSEdition
    • alphabetical order for rest entries based on the keys
  • Make PowerShell Core more resilient when being used with an account that doesn't have some key environment variables. (#3437)
  • Update PowerShell Core to accept the -i switch to indicate an interactive shell. (#3558)
    • This will help when using PowerShell as a default shell on Unix platforms.
  • Relax the PowerShell SemanticVersion constructors to not require 'minor' and 'patch' portions of a semantic version name. (#3696)
  • Improve performance to security checks when group policies are in effect for ExecutionPolicy. (#2588) (Thanks to @powercode)
  • Fix code in PowerShell to use IntPtr(-1) for INVALID_HANDLE_VALUE instead of IntPtr.Zero. (#3544) (Thanks to @0xfeeddeadbeef)

General cmdlet updates and fixes

  • Change the default encoding and OEM encoding used in PowerShell Core to be compatible with Windows PowerShell. (#3467) (Thanks to @iSazonov!)
  • Fix a bug in Import-Module to avoid incorrect cyclic dependency detection. (#3594)
  • Fix New-ModuleManifest to correctly check if a URI string is well formed. (#3631)

Filesystem-specific updates and fixes

  • Use operating system calls to determine whether two paths refer to the same file in file system operations. (#3441)
    • This will fix issues where case-sensitive file paths were being treated as case-insensitive on Unix platforms.
  • Fix New-Item to allow creating symbolic links to file/directory targets and even a non-existent target. (#3509)
  • Change the behavior of Remove-Item on a symbolic link to only removing the link itself. (#3637)
  • Use better error message when New-Item fails to create a symbolic link because the specified link path points to an existing item. (#3703)
  • Change Get-ChildItem to list the content of a link to a directory on Unix platforms. (#3697)
  • Fix Rename-Item to allow Unix globbing patterns in paths. (#3661)

Interactive fixes

  • Add Hashtable tab completion for -Property of Select-Object. (#3625) (Thanks to @powercode)
  • Fix tab completion with @{<tab> to avoid crash in PSReadline. (#3626) (Thanks to @powercode)
  • Use <id> - <name> as ToolTip and ListItemText when tab completing process ID. (#3664) (Thanks to @powercode)

Remoting fixes

  • Update PowerShell SSH remoting to handle multi-line error messages from OpenSSH client. (#3612)
  • Add -Port parameter to New-PSSession to create PowerShell SSH remote sessions on non-standard (non-22) ports. (#3499) (Thanks to @Lee303)

API Updates

  • Add the public property ValidRootDrives to ValidateDriveAttribute to make it easy to discover the attribute state via ParameterMetadata or PSVariable objects. (#3510) (Thanks to @indented-automation!)
  • Improve error messages for ValidateCountAttribute. (#3656) (Thanks to @iSazonov)
  • Update ValidatePatternAttribute, ValidateSetAttribute and ValidateScriptAttribute to allow users to more easily specify customized error messages. (#2728) (Thanks to @powercode)

6.0.0-alpha.18 - 2017-04-05

Progress Bar

We made a number of fixes to the progress bar rendering and the ProgressRecord object that improved cmdlet performance and fixed some rendering bugs on non-Windows platforms.

  • Fix a bug that caused the progress bar to drift on Unix platforms. (#3289)
  • Improve the performance of writing progress records. (#2822) (Thanks to @iSazonov!)
  • Fix the progress bar rendering on Unix platforms. (#3362) (#3453)
  • Reuse ProgressRecord in Web Cmdlets to reduce the GC overhead. (#3411) (Thanks to @iSazonov!)

Cmdlet updates

  • Use ShellExecute with Start-Process, Invoke-Item, and Get-Help -Online so that those cmdlets use standard shell associations to open a file/URI. This means you Get-Help -Online will always use your default browser, and Start-Process/Invoke-Item can open any file or path with a handler. (Note: there are still some problems with STA threads.) (#3281, partially fixes #2969)
  • Add -Extension and -LeafBase switches to Split-Path so that you can split paths between the filename extension and the rest of the filename. (#2721) (Thanks to @powercode!)
  • Implement Format-Hex in C# along with some behavioral changes to multiple parameters and the pipeline. (#3320) (Thanks to @MiaRomero!)
  • Add -NoProxy to web cmdlets so that they ignore the system-wide proxy setting. (#3447) (Thanks to @TheFlyingCorpse!)
  • Fix Out-Default -Transcript to properly revert out of the TranscribeOnly state, so that further output can be displayed on Console. (#3436) (Thanks to @PetSerAl!)
  • Fix Get-Help to not return multiple instances of the same help file. (#3410)

Interactive fixes

  • Enable argument auto-completion for -ExcludeProperty and -ExpandProperty of Select-Object. (#3443) (Thanks to @iSazonov!)

Cross-platform fixes

  • Ignore the -ExecutionPolicy switch when running PowerShell on non-Windows platforms because script signing is not currently supported. (#3481)
  • Standardize the casing of the PSModulePath environment variable. (#3255)

JEA fixes

  • Fix the JEA transcription to include the endpoint configuration name in the transcript header. (#2890)
