Subject: bug#30215: Visiting files from zip archives should not modify directory time
Date: Mon, 22 Jan 2018 23:52:48 +0200 [thread overview]
Message-ID: <87mv157e8f.fsf@mail.linkov.net> (raw)
Visiting a file from zip archive changes the modification time of
its directory. It's possible to prevent directory time modification
by setting ‘buffer-file-truename’ later after the extractor prepares
the file in its buffer:
diff --git a/lisp/arc-mode.el b/lisp/arc-mode.el
index adb3669..d6add45 100644
--- a/lisp/arc-mode.el
+++ b/lisp/arc-mode.el
