From 7835ee75cdffbce925246cbacc83e8b4a932a681 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Mon, 10 Mar 2025 08:13:23 +0100 Subject: environment: move access to "core.bigFileThreshold" into repo settings The "core.bigFileThreshold" setting is stored in a global variable and populated via `git_default_core_config()`. This may cause issues in the case where one is handling multiple different repositories in a single process with different values for that config key, as we may or may not see the correct value in that case. Furthermore, global state blocks our path towards libification. Refactor the code so that we instead store the value in `struct repo_settings`, where the value is computed as-needed and cached. Note that this change requires us to adapt one test in t1050 that verifies that we die when parsing an invalid "core.bigFileThreshold" value. The exercised Git command doesn't use the value at all, and thus it won't hit the new code path that parses the value. This is addressed by using git-hash-object(1) instead, which does read the value.
