我已经看过这篇文章中的答案(libgit2 (fetch & merge & commit)),但我正在努力让Git Pull工作。我没有收到任何错误消息。 Fetch似乎可以工作,但Merge不会发生。执行Git状态显示我的分支落后于1次提交...
On branch Branch_1_1.
Your branch is behind 'origin/Branch_1_1' by 1 commit, and can be fast-forwarded.
(use "git pull" to update your local branch)
nothing to commit, working directory clean
我的代码如下......
static int fetchhead_ref_cb(const char *name, const char *url,
const git_oid *oid, unsigned int is_merge, void *payload)
{
if ( is_merge )
{
strcpy_s( branchToMerge, 100, name );
memcpy( &branchOidToMerge, oid, sizeof( git_oid ) );
}
return 0;
}
void GitPull()
{
git_libgit2_init();
git_repository *repo = NULL;
git_remote *remote;
int error = git_repository_open( &repo, "C:\\work\\GitTestRepos\\Repo1" );
CHECK_FOR_ERROR
error = git_remote_lookup( &remote, repo, "origin" );
CHECK_FOR_ERROR
git_fetch_options options = GIT_FETCH_OPTIONS_INIT;
error = git_remote_fetch( remote, NULL, &options, NULL );
CHECK_FOR_ERROR
git_repository_fetchhead_foreach( repo, fetchhead_ref_cb, NULL );
git_merge_options merge_options = GIT_MERGE_OPTIONS_INIT;
git_checkout_options checkout_options = GIT_CHECKOUT_OPTIONS_INIT;
git_annotated_commit *heads[ 1 ];
git_reference *ref;
error = git_annotated_commit_lookup( &heads[ 0 ], repo, &branchOidToMerge );
CHECK_FOR_ERROR
error = git_merge( repo, (const git_annotated_commit **)heads, 1, &merge_options, &checkout_options );
CHECK_FOR_ERROR
git_annotated_commit_free( heads[ 0 ] );
git_repository_state_cleanup( repo );
git_libgit2_shutdown();
}
我在做什么导致合并不起作用?
答案 0 :(得分:2)
首先,git_checkout_options.checkout_strategy
有一个相当令人惊讶的默认值。它默认为干运行。因此,您可能希望将其更改为GIT_CHECKOUT_SAFE
。
要理解的第二件事是git_merge实际上没有提交合并。它仅为合并设置工作目录和索引。您仍然需要检查冲突并致电git_commit_create
完成合并。
但是,在这种特定情况下,您似乎并不需要合并。您的分支可以快进。调用git_merge_analysis
以确定要执行哪种合并。使用新的提取头快速转发当前分支上的git_reference_set_target
。
