Build-Parallel writes only to Output stream about invoke-build

With another commit pushed to this branch, we also support InformationVariable and this makes "logging" of information more useful.

We may choose what to use, InformationAction or InformationVariable or both

• InformationAction just causes the records to be "printed".
• InformationVariable tells where to keep them for the analysis with full meta information preserved.

Build-Parallel @(
    @{File='.build.ps1'; Task='Test'; Verbose=$true; InformationAction='Continue'; InformationVariable='InformationVariable'}
)
$InformationVariable | Select-Object Tags, MessageData | Out-String

produces

When could it be released?

Pretty soon, hopefully today or tomorrow. I am catching up at work after the holiday...

v5.10.4

[nightroman]

I would say it is expected, by design. Can we improve? Let me think about this, when I am back from my holiday 😁

[nightroman]

We may partially support some streams like Verbose and Information (Host
is included to Information). As a result, records are not lost, good. But we
cannot write them in the same order as they were written. All we can do is to
propagate record batches to the caller, one after another, e.g. verbose records
first, then information records.

Thus, in a sample similar to yours the call

Build-Parallel @(
    @{File='.build.ps1'; Task='Test'; Verbose=$true; InformationAction='Continue'}
)

produces

Start (1/1) C:\ROM\z\_230513_0649-ib212\.build.ps1
Build (1/1) C:\ROM\z\_230513_0649-ib212\.build.ps1:
VERBOSE: Write-Verbose

Task /Test
Write-Output

Build succeeded. 1 tasks, 0 errors, 0 warnings 00:00:00.1530057

Here is the branch with these changes https://github.com/nightroman/Invoke-Build/tree/work-212.
You may take Build-Parallel.ps1 from it and replace your current for local testing.

Hi Roman,

Thanks for the quick reply! I've tested it, and the usage of InformationVariable looks like a proper place for having those log entries.
