In fact, this constructor is called in 3 other classes:


It seems that the way to add extra smarts to this constructor is to change it to accept two arguments, the File object and either a TagSpec or a RevisionNumber. It would then map from one to the other in order to populate its internal information. This would have the benefit of maintainin correct internal information, and possibly being able to remove some code.

However, taking a look at the way it is used in DirectoryBranch pretty quickly shows that this would be ineffecient. It would require additional lookups for each file in get_file_branches(), significantly increasing the cost of this method. I suspect that similar situations apply to the other cases, they have already got easy access to the information they need, so doing it in the constructor would just make things slower.

Trading performance for a small amount of perceived elegance seems wasteful, so this bug is being deprioritized until it starts to cause problems.

There's something wrong with the FileBranch

It takes 3 args, but in both places where it's
called one of them is undef. There is no code in
the constructor. The solution is to put some
smarts into the FileBranch constructor, and remove
some code from the places where it's called.
