Really? At least "touch" did not originate in Redmond, but in
praised *nix. MS-DOS never had it AFAICT, only DR-DOS.
Anyway, if it is such a threat, then why Python allows to edit
timestamps (modify/access)? Other languages will do as well.
Dunno how "copy" is implemented, but in effect it just writes a new
file and then resets timestamps to those of the old original file,
even if it happens to overwrite an existing file of incidentally the very
same filesize and timestamp.
I won't delve into this any further, we are already far from the
original theme of plain performance, split apart 'cause of my
sidenote about this bug/gy behaviour.
My only point is there are a few reasons/circumstances/uses why
a file might have been modified without the timestamp being
modified as well and even unchanged filesize, and no matter if
these originate in user intent or application error or might generally
be considered a threat they are in this world and it would do no
harm if there were an *option* to stop SVN making performance-
optimizing guesses but just make sure - without deliberately
changing the timestamps of all files to force SVN to check hashes.
Do SVN developers follow this list or is there something like a wish
list?
