From eb22c1b46b85f7fac8467f991890d50853e4ca4d Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Tue, 26 Nov 2024 07:42:59 +0100 Subject: reftable/stack: add mechanism to notify callers on reload Reftable stacks are reloaded in two cases: - When calling `reftable_stack_reload()`, if the stat-cache tells us that the stack has been modified. - When committing a reftable addition. While callers can figure out the second case, they do not have a mechanism to figure out whether `reftable_stack_reload()` led to an actual reload of the on-disk data. All they can do is thus to assume that data is always being reloaded in that case. Improve the situation by introducing a new `on_reload()` callback to the reftable options. If provided, the function will be invoked every time the stack has indeed been reloaded. This allows callers to invalidate data that depends on the current stack data.
