Checkout comment not preserved under Emacs 24.5

[plopresti]

When I use "C-c v v" to check in, vc-clearcase used to populate the comment buffer with the checkout comment.

With Emacs 24.5, this comment is being erased and replaced by "Summary: ".

I have traced the behavior. First, the code in vc-clearcase-log-edit-mode runs and inserts the comment correctly (hooray!). But then, vc-log-edit invokes log-edit with the "setup" argument set to t. log-edit reacts by running (erase-buffer) followed by (run-hooks 'log-edit-hook).

I do not understand the logic that vc-log-edit uses to decide when the "setup" argument should be true, so I gave up and added this to my .emacs file:

(defun patlhack ()
;;; body of vc-clearcase-log-edit-mode here
)
(setq log-edit-hook 'patlhack)

Yes this is a huge hack, but it does appear to work around the problem.

I have no idea how to fix this "correctly".

Unfortunately I don't use this package anymore as I don't have access to a ClearCase installation...

However, looking at the code Emacs code, it seems that the setup argument is t when vc-log-fileset is different for the log buffer.

I think your fix, using a hook function is probably the best we can do. I will push a fix and let you know to try it out.
