From 9dcc09bed13aba0dc93d253f18ee2c7da5970c0c Mon Sep 17 00:00:00 2001 From: Toon Claes Date: Tue, 20 Jan 2026 22:47:11 +0100 Subject: [PATCH] last-modified: change default max-depth to 0 By default git-last-modified(1) doesn't recurse into subtrees. So when the pathspec contained a path in a subtree, the command would only print the commit information about the parent tree of the path, like: $ git last-modified -- path/file aaa0aab1bbb2bcc3ccc4ddd5dde6eee7eff8fff9 path Change the default behavior to give commit information about the exact path instead: $ git last-modified -- path/file aaa0aab1bbb2bcc3ccc4ddd5dde6eee7eff8fff9 path/file To achieve this, the default max-depth is changed to 0 and recursive is always enabled. The handling of option '-r' is modified to disable a max-depth, resulting in the behavior of this option to remain unchanged. No existing tests were modified, because there didn't exist any tests covering the example above. But more tests are added to cover this now.
