-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Corinna Vinschen on 5/22/2008 5:56 AM: | | While we're talking about coreutils, it would be a good idea to use the | latest Cygwin from CVS when testing coreutils further(*). cp baild out | on me because it used a NULL pathname in calls to futimesat, which I'd | consider a bug in coreutils, but the Linux man page gives away that this | is a GLIBC extension. I fixed that in CVS so futimesat can now do its | job (hopefully) correctly withe NULL pathname as well. | | However, here's a question: Should coreutils really use futimesat at | all when futimes and utimensat are available? Isn't that sort of a | buglet in coreutils?
Hmm. There's some history here. futimesat was the original proposal, then Posix 200x changed their minds and decided to standardize utimensat instead. Gnulib implemented a version prior to glibc, then glibc picked up the prototype that Posix was proposing which conflicted with gnulib (if I recall correctly, it was the addition of a flag parameter). Meanwhile, it IS a bit annoying that Posix 200x decided not to standardize utimensat(fd,NULL,times,flag) as changing the times on fd rather than treating fd as the directory starting point; once you have an open fd, having to refer to the file by name again is potentially racy. I wonder if, in all of the flurry in the Austin Group about changing futimesat to utimensat, that this use case was overlooked. But cygwin should certainly consider providing this as a useful extension, and coreutils should be taught to snoop whether systems with futimesat/utimensat support also honor this extension. - -- Don't work too hard, make some time for fun as well!
