Subject: bug#61256: master; Function `vc-find-revision-no-save' leaks buffers in case of errors
Date: Fri, 03 Feb 2023 17:24:45 +0100 [thread overview]
Message-ID: <871512d8f5344d0db2e8d9f28105ce25@vodafonemail.de> (raw)
I haven't actually a test case for this issue but found it by
re-indenting function `vc-find-revision-no-save'. When doing so you
will notice that the following sexps (indented as in the original code)
are actually both UNWINDFORMS:
(setq failed nil)
(when (and failed (unless buffer (get-file-buffer filename)))
(with-current-buffer (get-file-buffer filename)
(set-buffer-modified-p nil))
(kill-buffer (get-file-buffer filename)))
Meaning that the failure-handling `when' will never be eval'ed. I guess
this is a copy-and-paste error and the (setq failed nil) should be
rather placed in the preceeding (with-current-buffer ...).
Probably not a big deal but not hard to fix, either...
