From: Taylor Blau Date: Wed, 17 Jul 2024 21:12:19 GMT Subject: [PATCH v2 08/19] midx: teach `bsearch_midx()` about incremental MIDXs Message-ID: <38bd45bd24436d3404b089dff5c3d85f4026da97.1721250704.git.me@ttaylorr.com> In-Reply-To: Now that the special cases callers of `bsearch_midx()` have been dealt with, teach `bsearch_midx()` to handle incremental MIDX chains. The incremental MIDX-aware version of `bsearch_midx()` works by repeatedly searching for a given OID in each layer along the `->base_midx` pointer, stopping either when an exact match is found, or the end of the chain is reached.
