Research direction

Start with the TreeDefinition.Remove("sample/removed") call in the provided reproduction, then inspect how ObjectDatabase.CreateTree(current) processes recursive paths. Run the reproduction on LibGit2Sharp 2.7.2 and verify that the resulting tree does not contain sample/removed or its file.

Written by the indexing model from the issue text.

Description

Reproduction steps

Compile & run

using LibGit2Sharp;

Repository.Init(args[0]);
var repo = new Repository(args[0]);

TreeDefinition current = new();
current.Add("sample/stays/to/a/file", repo.ObjectDatabase.CreateBlob("stays".ToStream()), Mode.NonExecutableFile);
current.Add("sample/removed/to/a/file", repo.ObjectDatabase.CreateBlob("removed".ToStream()), Mode.NonExecutableFile);
current.Remove("sample/removed");

var tree = repo.ObjectDatabase.CreateTree(current);
var sig = new Signature("John Doe", "jd@example.com", DateTimeOffset.UtcNow);
var commit = repo.ObjectDatabase.CreateCommit(sig, sig, "Test", tree, new Commit[] { }, false);
var branch = repo.Branches.Add("main", commit, true);
repo.Refs.UpdateTarget(repo.Refs.Head, branch.Reference);
static class Ext
{
    public static Stream ToStream(this string data)
    {
        MemoryStream stream = new();
        StreamWriter writer = new(stream);
        writer.Write(data);
        writer.Flush();
        stream.Position = 0;
        return stream;
    }
}
