Currently, builds produced by *ceph-build* (as shown in Shaman) use the *default* build flavor. Since last year’s changes, the default build type is *RelWithDebInfo* [1]. In some testing scenarios, a *Debug* build type is useful, mainly to preserve built-in asserts and disable compiler optimizations. See Ceph’s *Build Types* [2]. Until now, the only way to get a Debug build was to use a branch name suffixed with *-debug. With the recent build flavor changes [3], each build now also produces a *debug* flavor. See the latest main builds [4] for an example. You can select the new flavor when scheduling tests using: `--flavor debug` It will also be used in nightly runs alongside the default flavor.
