It increases size of struct commit by ~12 bytes (assuming 4byte
allignment), and this is a popular structure. Besides, the three new
fields used by only git-describe, which nobody has in their top-ten
used commands (see "best git practices" thread). If the fields are so
badly needed (and the information can't (really?) be stored somewhere
else), maybe they could be at least compressed when not used:
struct commit_name_info {
unsigned int name_flags;
char name_prio;
char name[FLEX_ARRAY];
};
struct commit {
struct commit_list *parents;
struct tree *tree;
char *buffer;
struct commit_name_info *name_info;
};
BTW, do we still have some bits left in struct object->flags?
To, for example, switch between normal and expanded structure of
second-level object (i.e. commit and commit-with-names).
