Just noticed this while writing
https://public-inbox.org/git/[email protected]/ i.e. to
resolve the conflict with my commit-graph segfault fixing series.
This really should be something like:
/* earlier */
#define GRAPH_MAX_VERSION 2
if (!graph_version || graph_version > GRAPH_MAX_VERSION) {
error(_("commit-graph unsupported graph version %X, we support
up to %X"),
graph_version, GRAPH_MAX_VERSION);
Also, I'm confused as to what these patches are based on. Your is doing
"!= 1", but on "master" and ever since 2a2e32bdc5 ("commit-graph:
implement git commit-graph read", 2018-04-10) this has been the macro
"GRAPH_VERSION" instead of "1".
