So this only allows to delete expired things and setting the latest
when writing a new graph. Would we ever envision a user to produce
a new graph (e.g. via obtaining a graph that they got from a server) and
then manually rerouting the latest to that new graph file without writing
that graph file in the same process? The same for expired.
I guess these operations are just available via editing the
latest or deleting files manually, which slightly contradicts
e.g. "git update-ref", which in olden times was just a fancy way
of rewriting the refs file manually. (though it claims to be less
prone to errors as it takes lock files)
I imagine these alternatives for placing a new, latest commit graph file
would want Git to handle rewriting the "graph-latest" file. Given such a
use case, we could consider extending the 'commit-graph' interface, but
I don't want to plan for it now.
extern char *get_graph_latest_filename(const char *obj_dir);
+extern char *get_graph_latest_contents(const char *obj_dir);
Did

ever make it into tree? (It is sort of new, but I feel we'd want to
strive for consistency in the code base, eventually.)
Thank you for the reminder. I've removed the externs from 'commit-graph.h'.
Should I also remove the externs from other methods I introduce even
though their surrounding definitions include 'extern'?
Thanks,
