How to get changelog between HEAD and most recent tag? about git-changelog-plugin

[tomasbjerre]

It can now give you the most recent tag matching a semantic version.

You can construct a changelog between that tag and HEAD.

[webminster]

Is there any way to not use semantic versioning for this request? I'm building an AMI build pipeline that I'd like to use something else (like the release date) as version. But I'd have to look back to either the most recent tag, or most recent tag named "release" or something.

[tomasbjerre]

If you just want the most recent tag, perhaps this works? https://gist.github.com/rponte/fdc0724dd984088606b0

[webminster]

Am not having luck with 3.19 and getting tags. Is there a trick to what it's looking for?

I pushed a tag to the remote:
commit 069953e545e417cf89f5478dfcd5599e43e07500 (tag: 2022-02-11, tag: 1.0.0)
Author: Alan Sparks [email protected]
Date: Thu Feb 10 15:18:49 2022 -0700

Added this to a pipeline step:
def highestVersion = getHighestSemanticVersion()
currentVersion = highestVersion.findTag().orElse("")
println(" Git tag:" + currentVersion.toString())

But the printed value is empty.

Also had to add script approvals for se.bjurr.gitchangelog.internal.semantic.SemanticVersion findTag and for orElse().

Are you sure Jenkins is fetching the tags?

This is why I like to use the command line tool:
https://github.com/tomasbjerre/git-changelog-command-line#example---semantic-versioning-from-conventional-commits

Easier to fiddle with locally.

[webminster]

I'm seeing this in the Jenkins build log, I thought --tags would be including the tags. I was wanting to avoid installing NPM stuff on the server just for debugging...

11:04:40 > git fetch --tags --progress --prune -- [email protected]:CCoE/chglog.git +refs/heads/master:refs/remotes/origin/master # timeout=10
11:04:40 Checking out Revision 026ea085cf74bf

[tomasbjerre]

I ment you can use the command line locally. It uses the same code.

[webminster]

So, I'm a little lost. If I run "git tag", I get:
$ git tag
1.0.0
2022-02-11
release

If I run your utility, I get:
$ npx git-changelog-command-line --print-highest-version-tag
Exception in thread "main" java.util.NoSuchElementException: No value present
at java.base/java.util.Optional.get(Optional.java:148)
at se.bjurr.gitchangelog.main.Main.main(Main.java:746)

I see 1.0.0 there on the remote. Is the code looking for a tag format in particular?
-Alan

EDIT: I see - the tag has to be of format: vx.x.x.

[tomasbjerre]

Do you have just a few commits in the repo? A shallow clone maby? Is the tag on the first commit in the repo?
I actually found a bug here, perhaps same as you are experiencing.

[webminster]

I still can't figure out how to get what I need here. It's not making sense to me.

I have a branch, with a git log including:

Upgrade to Packer 1.7

`

So I've tried all the combinations of commits and refs I can think of, and the command line version keeps adding way more than between the HEAD and the tag or commit I'm trying to stop at (tag: 20220413, commit 56065b331d9fe444e71f215ec075e5036b8980cc):

It's even stranger to me that it picks it's own place in the log to stop, that 3/4 date isn't the first commit.
Is there a bug here? Is there no way to get the changes between HEAD and the most recent tag ref?
-Alan

[tomasbjerre]

It would be easier to understand your use case if you supplied a graph like:
git log --oneline --graph

[tomasbjerre]

The full graph, as in previous comment, and also the template being used would help understand this.

I made a test in this repo:

git clone [email protected]:tomasbjerre/git-changelog-lib.git
git checkout ba9d565

git log --oneline --graph 
* ba9d565 (HEAD) More settings can be set from command line
* 3950c64 [Gradle Release Plugin] - new version commit:  '1.1-SNAPSHOT'.
* 01484ce (tag: 1.0) [Gradle Release Plugin] - pre tag commit:  '1.0'.
* 83a8a7b Doc
* 5c54861 Test

OK, let me give something concrete. Maybe you can correct my understanding.

I have a git history like:

What I'm trying to do is get a changelog between the HEAD and to the tagged (20220413, commit 56065b331d9fe444e71f215ec075e5036b8980cc) on that branch. but I seem to keep going back farther, to commit 7897ca98ea38b16feb40d36cf70e61861580a55e.

Am I being stupid because there's a merge in there?
-Alan

[tomasbjerre]

This is intended. 7897ca9 is in the parents of HEAD and not in the parents of 20220413.

[tomasbjerre]

Perhaps this helps:
