Temporary files created by ArtifactBuilder persist even without building

[Shitaro]

I encountered an issue while trying to create an Artifact Archive file using the ArtifactBuilder class. When calling ArtifactBuilder.new_archive, an empty file is immediately created locally.

I expected this empty file to be automatically removed if the ArtifactBuilder.build method was not subsequently called. However, the file remains on the system. Even deleting the ArtifactBuilder object does not change this behavior.

Is this the intended behavior, or should this be considered a bug that needs fixing?

Below is the code to reproduce the issue:

from ommx.artifact import ArtifactBuilder

tag = "test"
filename = f"my_instance.ommx.{tag}"
image_name = f"my_instance:{tag}"

builder = ArtifactBuilder.new_archive(filename, image_name)
del(builder)  # Delete the object without calling build()
