[PATCH] cache-tree: use index state repository in trace2 calls

From: Jayesh Daga via GitGitGadget <gitgitgadget@gmail.com>
Date: Mar 31, 2026, 10:02 UTC
Message-ID: <pull.2259.git.git.1774951373588.gitgitgadget@gmail.com>

From: Jayesh Daga <jayeshdaga99@gmail.com>

trace2 calls in cache-tree.c use the global 'the_repository', even though cache_tree_update() has access to an explicit repository pointer via 'istate->repo'.

Using the global repository can result in incorrect trace2 output when multiple repository instances are in use, as events may be attributed to the wrong repository.

Use 'istate->repo' in cache_tree_update() to ensure correct repository attribution.

Other call sites are left unchanged as they do not have access to a repository instance.

    cache-tree: use index state repository in trace2 calls
    
    trace2 calls in cache-tree.c use the global 'the_repository', even
    though cache_tree_update() has access to an explicit repository pointer
    via 'istate->repo'.
    
    Using the global repository can result in incorrect trace2 output when
    multiple repository instances are in use, as events may be attributed to
    the wrong repository.
    
    Use 'istate->repo' instead in these call sites to ensure correct
    repository attribution.
