如何使用 libgit2sharp 获取文件 changed/removed/added？

Question

我有两个日期 - 从和到。我必须找到在该日期差异之间在存储库中更改的文件并列出它。这是一个相关的问题，它得到了树之间的差异。。

Answer 1

所以假设您正在尝试复制：

git log --reverse --since "11/10/2015" --until="11/15/2015" --format="%cD %s"

一旦您有了提交列表，ICommitLog，通过所有回购 Commits，过滤的分支列表等。您可以通过 Linq 进行过滤。

所以创建你的提交列表：

var repo = new Repository ("/Users/sushi/code/playscript/mono");
var filter = new CommitFilter {
    SortBy = CommitSortStrategies.Time | CommitSortStrategies.Reverse,
};
var commits = repo.Commits.QueryBy(filter);

现在使用 ICommitLog commits 对象，对提交对象应用 Linq 过滤器。在这种情况下，我使用提交者的日期并过滤从今天起 2 到 7 天的提交，但请记住还有一个 Author 日期：

var since = new DateTimeOffset(DateTime.Now.AddDays(-7));
var until = new DateTimeOffset(DateTime.Now.AddDays(-2));
var filteredCommitLog = commitLog.Where(c => c.Committer.When > since && c.Committer.When < until);
foreach (Commit commit in filteredCommitLog)
{
    Console.WriteLine("{0} : {1}", commit.Committer.When.ToLocalTime(), commit.MessageShort);
}

结果：

11/15/2015 5:32:36 AM -08:00 : [runtime] Fix Thread.CurrentThread in non-root appdomains by setting the tls slot in start_wrapper, otherwise Thread.CurrentThread would create a new Thread object so there would be two. Fixes #35828.
11/15/2015 12:00:30 AM -08:00 : Fix a warning.
....
11/10/2015 6:41:09 AM -08:00 : Merge pull request #2214 from kumpera/fix_enum_get_get_hashcode
11/10/2015 6:07:50 AM -08:00 : [Mono.Posix] Update incorrect test

更新：

我完全错过了这个答案的一部分，修改后的文件列表...:-/（需要更多咖啡）

git log --name-status --reverse --since "11/10/2015" --until="11/15/2015" --format="%cD %s"

变为：

    var since = new DateTimeOffset(DateTime.Now.AddDays(-7));
    var until = new DateTimeOffset(DateTime.Now.AddDays(-2));
    var filteredCommitLog = commitLog.Where(c => c.Committer.When > since && c.Committer.When < until);
    foreach (Commit commit in filteredCommitLog)
    {
        Console.WriteLine("{0} : {1}", commit.Committer.When.ToLocalTime(), commit.MessageShort);
        foreach (var parent in commit.Parents) {
            foreach (TreeEntryChanges change in repo.Diff.Compare<TreeChanges>(parent.Tree, commit.Tree)) {
                Console.WriteLine ("\t{0} :\t{1}", change.Status, change.OldPath);
            }
        }
    }

输出示例：

11/11/2015 8:09:41 AM -08:00 : Crashing test in mono_class_init() from a MonoGenericClass.

    Modified :  acceptance-tests/Makefile.am
    Modified :  acceptance-tests/SUBMODULES.json
    Modified :  acceptance-tests/versions.mk

要跳过日志并仅获取过滤后的提交列表中的文件列表：

 git log --name-status --since "11/10/2015" --until="11/15/2015" --format=""

变为：

foreach (TreeEntryChanges change in repo.Diff.Compare<TreeChanges>(filteredCommitLog.First().Tree, filteredCommitLog.Last().Tree)) {
    Console.WriteLine ("\t{0}\t:\t{1}", change.Status, change.OldPath);
}

示例输出：

Modified    :   acceptance-tests/SUBMODULES.json
Modified    :   external/referencesource

Answer 2

后来我确实采用了不同的方法来解决这个问题。

using(var repo = new Repository("c:\_Temp\Repo"))
{
 List<string> shalist = new List<string>();
 foreach(Commit c in repo.Commits)
 {
  DateTime since = DateTime.Parse("10/29/2015 12:00:00 AM");
  DateTime untill= c.Author.When.Date;

  if(untill >= since)
   {
     shalist.Add(c.sha.Tostring());
   }
  }

  Tree cmTree1 = repo.Lookup<Commit>(shalist.First()).Tree;  
  Tree cmTree2 = repo.Lookup<Commit>(shalist.Last()).Tree;

  var patch = repo.Diff.Compare<patch>(cmTree1, cmTree2);

  foreach(var ptc in patch)
  {
   Console.WriteLine(ptc.Path);
  }     
}

这将显示在 since - untill
