Remove code which delete GUID from Progress, Verbose, Debug and Warning messages by iSazonov · Pull Request #18871 · PowerShell/PowerShell

iSazonov · Dec 31, 2022

PR Summary

Since nobody can find where GUID is added to a message we can remove RemoveGuidFromMessage and RemoveIdentifierInfoFromMessage methods and wait feedback. I guess it is not used for years (maybe it was in psworkflows?).
Notice, the methods are perf expensive since process every message by Regex.

As the the pattern is known at compile time, could we use a regular expression source generator?

As the the pattern is known at compile time, could we use a regular expression source generator?

We could. But first I would like to know where we create this prefix. If it's remoting only, it's probably not worth it.

Suggested change

const string pattern = @"^([\d\w]{8}\-[\d\w]{4}\-[\d\w]{4}\-[\d\w]{4}\-[\d\w]{12}:\[.*\]:).*";

const string pattern = @"^[\d\w]{8}\-[\d\w]{4}\-[\d\w]{4}\-[\d\w]{4}\-[\d\w]{12}:\[.*\]:";

Remove the unnecessary capturing group and refactor:

message = message.Substring(matchResult.Length);`

Eh, I don't know that is real format of the messages - perhaps we need the capture group.

It looks like line 548 below uses the capture group. I would suggest replacing [\d\w] with [a-fA-F0-9] as \w is any alphanumeric character.

@SteveL-MSFT I mean line 548 can become message = message.Substring(matchResult.Length);

SteveL-MSFT · Jan 7, 2023

I'm trying to find out why this was originally needed and if it's still needed at all. I was able to find a related methods called GetIdentifierInfo() that extracts the information and it has out parameters for jobInstanceId (the guid), and computerName. So it appears to be related to jobs and remoting. However, I haven't found in the source where it's actually being set.

iSazonov · Jan 7, 2023

I see only AddSourceTagToError and CreateInformationalMessage.
Perhaps @PaulHigin can help.

SteveL-MSFT · Jan 9, 2023

@PaulHigin confirmed that this is used by remoting/jobs to de-multiplex multi-sessions so that alleviates my concern if this is dead code.

Since you're already updating this, perhaps we should change this regex a bit. Replace [\d\w] (which would accept any alphanumeric character making \d redundant anyways) to [a-fA-F0-9] to accept any hex digit.

@PaulHigin Could you please point the code (for error and progress bar too) where we add the GUID? Can there be some GUIDs and should we use capture group?

LGTM

To be honest I don't remember if/where Guids are added to remote information messages, or if they even are anymore. I seem to remember that in some cases they were added but, again, I cannot remember or find those cases in the code base. The RemoteData object contains all session routing information so I don't know why/when an information message would need a guid.

I cannot find too. I guess it is not used for years. I suggest to delete the code (RemoveIdentifierInfoFromMessage and RemoveGuidFromMessage) and wait feedbacks while we are at preview time.

pull-request-quantifier-deprecated · Feb 28, 2023

This PR has 29 quantified lines of changes. In general, a change size of upto 200 lines is ideal for the best PR experience!

Quantification details

Label      : Extra Small
Size       : +0 -29
Percentile : 11.6%

Total files changed: 2

Change summary by file extension:
.cs : +0 -29

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 detected.
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.
