Dynamic (DLR) objects work in some places today, but not others. This change expands that support to ForEach-Object, Where-Object and the family of cmdlets that use 'MshExpression' (Select-Object, etc.).
This change addresses both wildcard and non-wildcard cases. In wildcard cases, it uses the existing support of generating PSDynamicMember objects for names returned by GetDynamicMemberNames.
In non-wildcard cases, a dynamic property access is attempted whether or not the name shows up in GetDynamicMemberNames, but a truly "blind" access is only attempted if we see that the base object is an IDMOP. If the dynamic access fails, you'll get the same or a similar error experience as before ("The property 'Blarg' cannot be found", or no error at all, depending on the cmdlet and the strict mode setting).
The included test coverage includes a stub for the.ForEach operator--once people are happy with this change, I can continue by adding support there.
This change should allegedly also have positive perf impact, though in actual perf testing, although it does seem ever-so-slightly faster, I found it difficult to measure much difference at all.
Convert ShouldBeErrorId to Should -Throw -ErrorId in PowerShell tests.
Get rid of try { } catch { } formula to assert that errors were thrown.
Small fixes in tests to obey the new Pester -Parameter syntax.
Fix Select-Object.Tests.ps1 which might fail for Unix OS.
In the test, the processes which name matches i* are selected and it checks if there is non zero number of these processes. The test assumes that there is always at least one process, probably `init` - idle, but on Unix idle process does not have the name and hence the test might fail
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
There are mainly 2 changes:
1. When '-ExcludeProperty' is specified but '-Property' is not, use "*" as the default value for '-Property'.
2. Allow 'Select-Object -Property noexist-name' to return a PSObject with property noexist-name, unless noexist-name itself contains wildcards.
This restructuring moves tests to a directory name which matches the module
in which the cmdlet resides which should improve the discoverability of a
specific test.
For tests which are not about cmdlets in a module, new directories have been
created to make those tests easier to find as well
