[PATCH 4/5] Keep '*' in pattern refspecs

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

 



In order to do anything more capable with refspecs, the first step is
to keep the entire input. Additionally, validate patterns by checking
for the ref matching the rules for a pattern as given by
check_ref_format(). This requires a slight change to make it require
the '*' to be at the beginning of a path component.
