I wonder if you can further reduce an unnecessary duplication in the
two "else if" clauses in the above, and if the result becomes easier
to read and maintain. Perhaps
if (((flags & LOOKUP_LITERALLY)
? unpack_sha1_header_to_strbuf(...)
: unpack_sha1_header(...)) < 0)
status = error(...);
else if ((status = parse_sha1_header_extended(...)) < 0)
status = error(...);
or even
status = 0;
if (flags & LOOKUP_LITERALLY) {
if (unpack_sha1_header_to_strbuf(...) < 0)
status = error(...);
} else {
if (unpack_sha1_header(...) < 0)
status = error(...);
}
if (!status) {
if (status = parse(...)) < 0)
status = error(...);
}
although I think the latter might be a bit harder to read.
