From: Tassilo Horn <tsdh <at> gnu.org> To: bug-gnu-emacs <at> gnu.org Subject: 31.0.50; Dired misses or double-processes files when auto-revert-mode is enabled Date: Fri, 17 Jan 2025 08:42:42 +0100I have a directory test/ with files foobar.N for N in 0 to 99 and do: emacs -Q test M-x auto-revert-mode RET % m .* RET ; mark all files Z ; compress them all Z ; uncompress them all again Z ; again and again... ... I always wait until the (un)compress operations are all done before pressing Z again. But even though, at some Z you will notice that your directory doesn't contain only gz or only non-gz files but a mix of both! It seems the reason is that auto-revert-mode at some point reverts the buffer at random points in time while dired is still (un)compressing and that changes the order of files so that it either misses files or processes some files twice. It also seems it is more likely to catch the error when the files take some time to (un)compress, so I filled them with head -c 1000000 /dev/urandom | strings i.e., random but long enough content. I've had that issue just half an hour ago with a directory containing similar gzipped large logfiles. There, the error hit me so hard that I basically had an infloop where the same files seemed to be uncompressed and then compressed over and over again, with just a single "mark all" and dired-do-compress operation.
