Subject: [PATCH v3 0/3] sparse-checkout: fix segfault on malformed patterns
Date: Wed, 15 Dec 2021 13:46:05 +0000 [thread overview]
Message-ID: <pull.1069.v3.git.1639575968.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1069.v2.git.1639149490.gitgitgadget@gmail.com>
This series fixes some issues with parsing sparse-checkout patterns when
core.sparseCheckoutCone is enabled but the sparse-checkout file itself
contains patterns that don't match the cone mode format.
The first patch fixes a segfault first reported in [1]. The other two
patches are from an earlier submission [2] that never got picked up and I
lost track of. There was another patch involving 'git sparse-checkout init
--cone' that isn't necessary, especially with Elijah doing some work in that
space right now.

commit in v2

* Added Elijah's review.

@@ Commit message
there is additional logic that attempts to remove the line from the hashset
and free the data. This leads to a segfault in the 'git sparse-checkout
list' command because it iterates over the contents of the hashset, which is
- no invalid.
+ now invalid.
The fix here is to stop trying to remove from the hashset. Better to leave
bad data in the sparse-checkout matching logic (with a warning) than to
