[PATCH v11 07/12] reftable: clarify how empty tables should be written

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Han-Wen Nienhuys <hanwen@xxxxxxxxxx>

The format allows for some ambiguity, as a lone footer also starts
with a valid file header. However, the current JGit code will barf on
this. This commit codifies this behavior into the standard.
