Azure Devops Git - Get version by date

Question

Recently I moved from TFVC to Git Version control. Up until now I have been getting the file items for a specific date using TfvcVersionDescriptor date type like this:

var version = new TfvcVersionDescriptor { VersionType = TfvcVersionType.Date, Version = date };

Is there any way to achieve this using GitHttpClient? I need to generate some trend analysis and getting the list of files for a specific date is very important. If there is no functionality to retrieve by date, is there a work around for this?

Answer 1

Use GitHttpClient.GetCommitsAsync with a GitQueryCommitsCriteria object similar to

GitQueryCommitsCriteria searchCriteria = new GitQueryCommitsCriteria()
{
    FromDate = new DateTime(2019, 2, 2).ToString(),
    ToDate = DateTime.Now.ToString(),
    ItemVersion = new GitVersionDescriptor()
    {
        Version = "master",
        VersionType = GitVersionType.Branch
    }
};
var commits = await client.GetCommitsAsync(repo.Id, searchCriteria);

It will return a List<GitCommitRef> with GitCommitRef.CommitId (SHA-1) to identify the commit.

And then use GitHttpClient.GetItemsAsync or another variation with

new GitVersionDescriptor()
{
    VersionType = GitVersionType.Commit,
    Version = commitId // value from above
};

to get the files.
