[New-bugs-announce] [issue10824] urandom should not block

[Michal Čihař]

New submission from Michal Čihař <michal at cihar.com>:

Currently if /dev/urandom does not provide any data, unradom() call is just stuck infinitely waiting for data.

I actually faced this issue when /dev/urandom was empty regular file (due to bug in pbuilder, but I don't think it matters how it did happen) and urandom() call just hang. I think it would be much saner in such case to throw an error and let user know that something it wrong than waiting infinitely.
