Question

我删除文件：用户git_remove_bypath和git_index_write

我使用索引来提交，而不是通过删除的文件来提交文件，但是通过删除的文件也可以提交成功。

int commit(void *repository, const char *file_name[], const unsigned int file, const char *message, void *payload)
{
    int error = -1;
    git_signature *signature = NULL;
    /*git git;  identify of any object*/
    /*git commit_id; identify of any object*/
    void* index = NULL;
    void* tree = NULL;

    do  /* try catch */
    {
        const char *path = git_repository_path((git_repository*)repository);
         /*get signature*/
        error = git_signature_default(&signature, (git_repository*)repository);
         /*get repository head*/
        error = git_repository_head(&ref_head,(git_repository*)repository);
        if (error == GIT_OK)
        {
            error = git_commit_lookup(&parent_commit, (git_repository*)repository, git_reference_target(ref_head));

        }
        else if (error != -9)
        {
            break;
        }
         /*get repository index*/
        error = git_repository_index((git_index**)&index, (git_repository*)repository);

        for(int i = 0; i < Count; ++i)
        {
             /*get statue*/
            error = git_status_file(&flags, (git_repository *)repository, file_name[i]);
            if(-3 == error || -5 == error)
            {
                continue;
            }

            if( GIT_STATUS_INDEX_DELETED & flags || GIT_STATUS_WT_DELETED & flags )
            {
                 /*remove file*/
                error = git_index_remove_bypath((git_index *)index, file_name[i]);  
            }
            else
            {
                 /*add file*/
                error = git_index_add_bypath((git_index *)index, file_name[i]);
            }
            /*write disk*/
            error = git_index_write((git_index*)index);    

        }

        /* Get the index and write it to a tree */
        error = git_index_write_tree(&git, (git_index*)index);
        /* lookup tree */
        error = git_tree_lookup((git_tree**)&tree, (git_repository *)repository, &git);

        /* Do the commit*/
        error = git_commit_create(&commit_id, (git_repository*)repository, "HEAD", signature, signature, NULL,
message, (git_tree *)tree, 1, parents);  
    }while(0);

 }

Answer 1

1. Delete file 1.txt
git_remove_bypath(index, "1.txt")
git_index_write(index)

2. git status
On branch master
   Changes to be committed:
   deleted:   1.txt
Changes not staged for commit:
   modified:  2.txt

3.only want to commit modified file 2.txt

git_index_add_bypath(index, "2.txt");  // just commit 2.txt,don't selected 1.txt. 
git_index_write(index);
git_index_write_tree(&git_oid, index);
git_tree_lookup(&git_tree, repo, &gitoid);
git_commit_create(&commit_oid, repo, "HEAD",signature, signature, NULL, message, git_tree, 1, parents_commit);

4. git status 
on branch master
nothing to commit, working tree clean

Question:
Why the deleted file is also committed? How can I only commit "2.txt" without commit "1.txt"?
Just like tortoise git, delete the file by menu command, after that user can only commit the modified file("2.txt")

为什么在libgit2中使用commit命令时，默认情况下会提交删除的文件？
