由于没有使用libgit2 as far as I can tell在磁盘上使用文件来创建提交的复制粘贴示例,我认为我应该添加一个。
不要忘记libgit2目前处于全面开发阶段(2013年3月),因此请查看官方文档和源代码,因为每天都会添加新功能:
答案 0 :(得分:2)
bool addGitCommit (
git_repository * repo, git_signature * sign,
const char * content, int content_sz,
const char * message )
{
int rc; /* return code for git_ functions */
git_oid oid_blob; /* the SHA1 for our blob in the tree */
git_oid oid_tree; /* the SHA1 for our tree in the commit */
git_oid oid_commit; /* the SHA1 for our initial commit */
git_blob * blob; /* our blob in the tree */
git_tree * tree_cmt; /* our tree in the commit */
git_treebuilder * tree_bld; /* tree builder */
bool b = false;
/* create a blob from our buffer */
rc = git_blob_create_frombuffer(
&oid_blob,
repo,
content,
content_sz );
if ( rc == 0 ) { /* blob created */
rc = git_blob_lookup( &blob, repo, &oid_blob );
if ( rc == 0 ) { /* blob created and found */
rc = git_treebuilder_create( &tree_bld, NULL );
if ( rc == 0 ) { /* a new tree builder created */
rc = git_treebuilder_insert(
NULL,
tree_bld,
"name-of-the-file.txt",
&oid_blob,
GIT_FILEMODE_BLOB );
if ( rc == 0 ) { /* blob inserted in tree */
rc = git_treebuilder_write(
&oid_tree,
repo,
tree_bld );
if ( rc == 0 ) { /* the tree was written to the database */
rc = git_tree_lookup(
&tree_cmt, repo, &oid_tree );
if ( rc == 0 ) { /*we've got the tree pointer */
rc = git_commit_create(
&oid_commit, repo, "HEAD",
sign, sign, /* same author and commiter */
NULL, /* default UTF-8 encoding */
message,
tree_cmt, 0, NULL );
if ( rc == 0 ) {
b = true;
}
git_tree_free( tree_cmt );
}
}
}
git_treebuilder_free( tree_bld );
}
git_blob_free( blob );
}
}
return b;
}
存储库来自git_repository_init()
或git_repository_open()
。
签名来自git_signature_now()
或git_signature_new()
。
该函数更新当前分支的HEAD。
如果在执行该功能后执行git status
,您会注意到文件name-of-the-file.txt
显示为已删除。这是因为该函数不会创建实际文件,只会创建git数据库中的条目。
另外,请注意git_commit_create()
的最后一个论点。 0和NULL表示这是第一个(根)提交。对于所有其他应该至少应该指定父提交,可以使用git_commit_lookup()
获得。
<小时/> 我只是在学习这些东西。如果您了解更多,请改进此答案。
