[ISSUE]: NotImplementedException in TrunkBased-Workflow

[steven-r]

Prerequisites

• I have written a descriptive issue title
• I have searched issues to ensure it has not already been reported

GitVersion package

GitVersion.Tool

GitVersion version

6.0.0-rc1

Operating system

Linux, Windows

What are you seeing?

When running gitversion on my git repos, I receive a NotImplementedException.

I was using Mainline for the past and I'm trying out the 6.0-RC1 release now.

What is expected?

A valid version description.

Steps to Reproduce

use my repos (it's private, sorry), with the following configuration:

workflow: TrunkBased/v1
patch-version-bump-message: "^(text|fix|perf|refactor|revert|style|test)(\\([\\w\\s-]*\\))?:"

RepositoryFixture Test

No response

Output log or link to your CI build (if appropriate).

[HHobeck]

Please analyze this issue in more detail and simplify your scenario. In advance provide:

• git commands and/or
• an integration test

to reproduce this issue.

Please notice: The NotImplementedException indecates that multiple is-main-branch: true branches have been used with the Mainline version strategy. In version 6.x this is not supported and will be probably implemented in version 7.x:

• [Feature]: Support of multi mainline branches in the Mainline version strategy #4057

[brendankowitz]

When upgrading to 6 I've noticed the same stacktrace from the build server on merge commits, just trying to understand what the right config should be here...
It looks like the solution is to either turn off "is-main-branch" (which seems to give the wrong version) or turn off "track-merge-message" to prevent that codepath in the merge build.

GitVersion/src/GitVersion.Core/VersionCalculation/VersionSearchStrategies/MainlineVersionStrategy.cs

Lines 226 to 242 in a4dde97

	if (item.IsMergeCommit())
	{
	Lazy<IReadOnlyCollection<ICommit>> mergedCommitsInReverseOrderLazy = new(
	() => incrementStrategyFinder.GetMergedCommits(item, 1, Context.Configuration.Ignore).Reverse().ToList()
	);
	if ((configuration.TrackMergeMessage ?? Context.Configuration.TrackMergeMessage) == true
	&& MergeMessage.TryParse(item, Context.Configuration, out var mergeMessage))
	{
	if (mergeMessage.MergedBranch is not null)
	{
	var childConfiguration = Context.Configuration.GetBranchConfiguration(mergeMessage.MergedBranch);
	var childBranchName = mergeMessage.MergedBranch;
	if (childConfiguration.IsMainBranch == true)
	{
	if (configuration.IsMainBranch == true) throw new NotImplementedException();

[peterbomers]

I think this occurs when there is a merge message on te main branch.
The childConfiguration is the same as the current configuration and the exception is thrown.

[daghsentinel]

Tip: I removed regex: main from the main branch definition in GitVersion.yml and this error went away.

[steven-r]

After some digging, cloing the sources and add debug information I can confirm that these are merge requests towards Main coming from PRs. What fixed he problem was to add the malicious merges to the ignore list.

Anyhow, this git "tree" was a result out of working git operations.
Instead of throwing an error/exception, gitversion should ignore those merges to behave like 5.x

[asbjornu]

@steven-r, sure. If you can figure out a way to ignore such commits without breaking any existing tests, we would be happy to accept a pull request.

[HHobeck]

@steven-r Can you please create a minimal example or somehow a visual representation to have a basis for the discussion? Would be very good.

Actually I'm not sure if a merge commit from main is generally a good idea in the TrunkBased workflow. Anyway ignoring the commit is not what I would expect. I would expect at least that it will be handled like a normal commit. What do you think?

[thomhurst]

I've just managed to replicate it.

• I pull main
• Someone else commits and pushes to main
• I commit and push to main, but don't have the latest now
• Git merges latest for me and makes a commit with a message "[Merge remote-tracking branch 'origin/main']
• GitVersion now fails with exception

Git Log output:

[steven-r]

My real use case is a list of dependabot updates on main where there's no rebase in between (as it is not needed in all cases).

I've just managed to replicate it.

• I pull main
• Someone else commits and pushes to main
• I commit and push to main, but don't have the latest now
• Git merges latest for me and makes a commit with a message "[Merge remote-tracking branch 'origin/main']
• GitVersion now fails with exception

[thomhurst]

I've tried ignoring those commits and now I'm getting a brand new error:

Just putting it out there for future reference.
I fixed it by track-merge-message: false as I dont care about commit messages for version manipulation
