PR Summary

Fixes #12762

Add an -Options parameter to Invoke-Command and Start-PSSession to pass SSH options

  • Options parameter added to Invoke-Command
  • Options parameter added to Start-PSSession
  • Options parameter added to Enter-PSSession
  • Options parameter added to SSHConnection Hashtable

PR Context

PSRP over SSH uses OpenSSH to connect to remote machines. It would be helpful if we could pass OpenSSH options to cmdlets that support PSRP over SSH.

These changes look good to me, but can you also update the Enter-PSSession command? SSH remoting is supported by Invoke-Command, New-PSSession, and Enter-PSSession.

@PaulHigin @iSazonov Thanks for reviewing this so quickly! WIP is removed. I'll take a look at the docs later this week. Let me know if you need anything else.

Since we get this through public API should we make additional validations?
I mean that Key and Value could contain composite values.

I see your point, right now the Format method will just try to convert whatever is passed in to a string, would we want to handle composite values any other way?

I also could try to add some validation to ensure that we're only passing options that OpenSSH would consider valid, but that would be a lot to maintain as well. Please let me know your thoughts.

This test checks that the parameter is only recognized, but does not verify that it is being applied.

I can definitely add more integration tests, it will take me a few days to get those done though.

@pull-request-quantifier-deprecated

This PR has 54 quantified lines of changes. In general, a change size of upto 200 lines is ideal for the best PR experience!


Quantification details

Label      : Small
Size       : +50 -4
Percentile : 21.6%

Total files changed: 6

Change summary by file extension:
.cs : +45 -4
.ps1 : +5 -0

Change counts above are quantified counts, based on the PullRequestQuantifier customizations.

Why proper sizing of changes matters

Optimal pull request sizes drive a better predictable PR flow as they strike a
balance between between PR complexity and PR review overhead. PRs within the
optimal size (typical small, or medium sized PRs) mean:

  • Fast and predictable releases to production:
    • Optimal size changes are more likely to be reviewed faster with fewer
      iterations.
    • Similarity in low PR complexity drives similar review times.
  • Review quality is likely higher as complexity is lower:
    • Bugs are more likely to be detected.
    • Code inconsistencies are more likely to be detetcted.
  • Knowledge sharing is improved within the participants:
    • Small portions can be assimilated better.
  • Better engineering practices are exercised:
    • Solving big problems by dividing them in well contained, smaller problems.
    • Exercising separation of concerns within the code changes.

What can I do to optimize my changes

  • Use the PullRequestQuantifier to quantify your PR accurately
    • Create a context profile for your repo using the context generator
    • Exclude files that are not necessary to be reviewed or do not increase the review complexity. Example: Autogenerated code, docs, project IDE setting files, binaries, etc. Check out the Excluded section from your prquantifier.yaml context profile.
    • Understand your typical change complexity, drive towards the desired complexity by adjusting the label mapping in your prquantifier.yaml context profile.
    • Only use the labels that matter to you, see context specification to customize your prquantifier.yaml context profile.
  • Change your engineering behaviors
    • For PRs that fall outside of the desired spectrum, review the details and check if:
      • Your PR could be split in smaller, self-contained PRs instead
      • Your PR only solves one particular issue. (For example, don't refactor and code new features in the same PR).

How to interpret the change counts in git diff output

  • One line was added: +1 -0
  • One line was deleted: +0 -1
  • One line was modified: +1 -1 (git diff doesn't know about modified, it will
    interpret that line like one addition plus one deletion)
  • Change percentiles: Change characteristics (addition, deletion, modification)
    of this PR in relation to all other PRs within the repository.
