Matthieu Brouillard commented on SCM-885:
-----------------------------------------
With the patch it is clear that calling GitChangeLogCommand#createCommandLine()
with a null startVersion will not result anymore in issuing the git log command
`..EndVersion` and thus will not result anymore in being interpreted by
`HEAD..EndVersion`.
But still, the ones who will want to retrieve the log between HEAD and
EndVersion will be able to do so by explicitly use "HEAD" as the start version.
Additionaly the ones, like me, expecting to be able to query the log between
the initial commit (unknown/null startVersion) of a repository and a given
commit (even HEAD) can do it.
Instead of changing the interpretation like the patch does perhaps that you
prefer a new API to allow to query from the origin(first commit). This way the
enhancement will be backward compatible (even if non intuitive IMHO).
The use case for me is that we have a maven-plugin (that delegates to maven-scm
API) to compute between two calls what has changed in term of commits on a
project. But the first time we query the log we have no initial commit (thus
starVersion null) and we want the log between the inital commit and HEAD.
> GitChangeLogCommand is wrong when only endVersion is set

> Invoking execution of a GitChangeLogCommand where only the end revision has
> been set produces a wrong out.
> +Actual result:+
> {{git whatchanged --date=iso ..END_REVISION_SHA1 -- PROJECT_PATH}}
> +Expected result:+ only the end revison SHA1 is used without the two dots
> {{git whatchanged --date=iso END_REVISION_SHA1 -- PROJECT_PATH}}
