Sergey Vlasov, Andy Parkins and Alex Riesen all pointed out that it is possible for a single invocation of receive-pack to be given more refs than the OS might allow us to pass as command line parameters to a single hook invocation. We don't want to break these up into multiple invocations (like xargs might do) as that makes it impossible for the pre-receive hook to verify multiple related ref updates occur at the same time, and it makes it harder for post-receive to send out a single batch notification. Instead we pass the reference data on a pipe connected to the hook's stdin, supplying one ref per line to the hook. This way a single hook invocation can obtain an infinite amount of ref data, without bumping into any operating system limits. Signed-off-by: Shawn O.
