I would rather we keep "const struct index_state*" if we could. I tried putting "const" back and found that ce_match_stat_basic() calls set_istate_ops(), which writes to "struct index_state". Putting set_istate_ops() in ce_match_stat_basic() may seem convenient, but does not make much sense (why would a match_stat function update index_ops?). I think you could move it out and - read_index calls set_istate_ops - (bonus) discard_index probably should reset "version" field to zero and clear internal_ops - the callers that use index without read_index must call initialize_index() or something, which in turn calls set_istate_ops. initialize_index() may take the preferred index version - do not let update-index modifies version field directly when --index-version is given. Wrap it with set_index_version() or something, so we can do internal conversion from one version to another if needed - remove set_istate_ops in write_index(), we may need internal_ops long before writing. When write_index is called, internal_ops should be already initialized -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
