[PATCH v3 09/17] object-file.c: make parse_loose_header_extended() public

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

 



Make the parse_loose_header_extended() function public and remove the
parse_loose_header() wrapper. The only direct user of it outside of
object-file.c itself was in streaming.c, that caller can simply pass
the required "struct object-info *" instead.

This change is being done in preparation for teaching
read_loose_object() to accept a flag to pass to
parse_loose_header(). It isn't strictly necessary for that change, we
could simply use parse_loose_header_extended() there, but will leave
the API in a better end state.
