[BUG]: GitVersion (in Azure Devops) calculating wrong version when building a tag

[arnoschuring-miele]

Prerequisites

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

GitVersion package

AzureDevops task

GitVersion version

5.12.0

Operating system

Linux

What are you seeing?

When building on a tag in Azure Devops, GitVersion is generating a new pre-release version rather than using the already-placed tag. This seems entirely similar to #2074 and #2456.

The current config is quite minimal:

commit-date-format: yyyyMMdd
mode: Mainline
tag-prefix: '[vV]_'

I cannot run this locally to get more info, because a) when I do a git checkout of the tag locally, it generates the correct version number, and b) it seems to completely ignore any -verbosity argument specified.

I suspect this line (from the log) is the problem:

Detected forward merge [..] ; rewinding mainline to previous commit

And that may be because we merged the same branch twice:

*   dc43f3b (HEAD, tag: v_0.1.2, origin/main, main)
|\
| * 9e67e70 (origin/feature/1648-snip-branch-name, feature/1648-snip-branch-name)
* | 0ec823e
|\|
| * 7648056
| * 0daea29
| * f31a425
| * f83209c
| * 1c3ef10

|/
* a102d74

What is expected?

GitVersion should generate a version number that matches exactly the already-placed tag v_0.1.2 (as it does locally)

Steps to Reproduce

I have not been able to reproduce this locally, even with the exact git checkout procedure that ADO is using:

git init
git remote add origin $devops_repo_url
git fetch origin --tags
git fetch origin +dc43f3be8e9f7d955998e0554fdfb4286bfbdfee
git checkout --progress --force dc43f3be8e9f7d955998e0554fdfb4286bfbdfee
../gitversion.exe -verbosity diagnostic -config ../deployment-automation/config/gitversion.yaml

I believe this is fixed in v6. Can you upgrade and try it out?

[arnoschuring-miele]

It doesn't seem fixed, as GitVersion still generates a prerelease version. I had to change mode: Mainline to workflow: TrunkBased/v1 but I did not make any other changes to the config file. I'm not sure if that is correct, but I still see this line in the output logs:

INFO [04/30/24 13:09:20:46] TrunkBasedVersionStrategy: Force version increment '0.1.2' +semver 'Patch' with label 'tags-v_0-1-2' based on commit 'dc43f3b'.

and I don't think it should add any +semver here because commit dc43f3b is exactly the commit where tag v_0.1.2 points to.

This is the full output from a v6 run:

@HHobeck, is it expected behavior that tagged commits aren't picked up with the TrunkBased workflow?

[davidkeaveny]

If it's any help, I'm seeing the same issue when using GitVersion 5.10.3 on GitHub Actions. If I create a release in GitHub and tag it as e.g. 0.0.0-beta+7 and run dotnet-gitversion locally, then the pre-release tag is correctly generated as beta+7, but when my GitHub action executes, the pre-release tag is calculated as tags-0-0-1-beta-7.1

[HHobeck]

@HHobeck, is it expected behavior that tagged commits aren't picked up with the TrunkBased workflow?

To answer your question: Yes of course the TrunkBased workflow (which uses the Mainline version stratgey) considers tags. Anyway I think it has nothing to do with the used strategy. If you see the log output then you see the following:

Branch from build environment: refs/tags/v_0.1.2

That means the current branch is of name tags/v_0.1.2. Because we have no branch configuration with name tags the algorithm uses the unknown branch configuration.

  unknown:
    increment: Patch
    regex: (?<BranchName>.+)
    prevent-increment:
      when-current-commit-tagged: false
    source-branches:
    - main
    pre-release-weight: 30000

[asbjornu]

@HHobeck as I suspected. So it is the repository normalization that is causing this problem, which I thought was fixed. Oh well.

[HHobeck]

@HHobeck as I suspected. So it is the repository normalization that is causing this problem, which I thought was fixed. Oh well.

The normalization process is something I have not touched. I have a common understanding what this module does but don't know the overall design. I think the behavior having a branch with name e.g. tags/1.0.0 is also something I have seen with azure devops as well.

Maybe it is by design and we need to change the configuration and add a tags branch configuration? Or let me ask the question different: Which branch would you use in the normalization process when starting the artefact creation by selecting just a tag? Maybe this discussion goes in the same direction: #3907

[arnoschuring-miele]

Note that this is only an issue in Mainline mode. If I change my configuration to mode: ContinuousDelivery, the tag gets used correctly (even with the weird refs/heads/tags/ local branch):

Note that this is only an issue in Mainline mode. If I change my configuration to mode: ContinuousDelivery, the tag gets used correctly (even with the weird refs/heads/tags/ local branch):

@arnoschuring-miele: In the log output you see the following line:

Branch from build environment: refs/tags/v_0.1.3

That means independent of wish mode you are using there is no configuration for tags in the configuration present. Maybe I need to say that I have no idea why it is not working with the Mainline mode. Anyway I want to point out that the Mainline mode is deprecated and will be removed in version 6.x. The equivalent mechanism will be the Mainline version strategy (which has been developed completely new with a different code base).

[asbjornu]

As I wrote in #4183 (reply in thread):

It seems like this is related to #2074, #2456, and #4015. I think what GitVersion needs to do is a ref-check of the checked out commit SHA, and if a tag is found matching the branch name, follow the logic as if it was a tagged commit on the main branch.

[DSpirit]

I ran into the same issue using GitVersion 6.0.2 and Azure DevOps.
Currently I'm trying to get release branches running in ContinuousDeployment mode and thus, had the necessity for tagging the release branches.

Unfortunately the tagged branches produced semantic versions as follows:

{
  "AssemblySemFileVer": "25.4.2.0",
  "AssemblySemVer": "25.4.2.0",
  "BranchName": "tags/25.4.0",
  "BuildMetaData": 0,
  "CommitDate": "2024-09-08",
  ...
  "FullSemVer": "25.4.2-tags-25-4-0.1+0"
}

For now, I've just managed to workaround adding a tag branch as follows:

tags: 
  mode: ContinuousDeployment
  regex: tags?[/-]\d+\.\d+\.\d+ 
  source-branches: ['main','release','hotfix']  
  increment: none

Using this change, tags are receiving a semantic version as desired:

{
  "AssemblySemFileVer": "25.7.0.0",
  "AssemblySemVer": "25.7.0.0",
  "BranchName": "tags/25.7.0",
  "BuildMetaData": null,
  "CommitDate": "2024-09-08",
  ...
  "FullSemVer": "25.7.0"
}

Nevertheless, this is not optimal as it doesn't take tagPrefixes etc. into account.
