I want to merge my develop in my master branch with LibGit2Sharp, but I can't find any examples on the GitHub wiki of LibGit2Sharp.
How can I do that?
Code snippet:
using (var repo = new Repository(repoDirectory))
{
var masterBranch = repo.Branches["master"];
var developBranch = repo.Branches["develop"];
Commands.Checkout(repo, masterBranch);
// merge dev in master
// tag master
Commands.Checkout(repo, developBranch);
// merge master in dev
}
I found a solution, I'm not sure if it could be done in another way, but I works.
using (var repo = new Repository(repoDirectory))
{
var masterBranch = repo.Branches["master"];
var developBranch = repo.Branches["develop"];
var merger = new Signature(AuthorName, AuthorEmail, DateTime.Now);
Commands.Checkout(repo, masterBranch);
repo.Merge(developBranch, merger, new MergeOptions());
repo.ApplyTag("v0.1");
Commands.Checkout(repo, developBranch);
repo.Merge(masterBranch, merger, new MergeOptions());
}

I am writing a program that manipulates a git repo using the LibGit2Sharp library. One of the operations that I need to perform is a rebase to incorporate changes made to the master into a branch. How do I perform a git rebase master command using LibGit2Sharp? I haven't been able to find any examples of this.
What about something like
using(var repo = new Repository("path"))
{
var id = new Identity("name", "email");
var opt = new RebaseOptions();
var rebaseResult = repo.Rebase.Start(
featureBranch,
masterBranch,
null,
id,
opt);
}
The following is based on dontbyteme but will do a git pull --rebase:
using var gitRepo = new LibGit2Sharp.Repository(r.Path);
var remote = r.Network.Remotes["origin"];
var refSpecs = remote.FetchRefSpecs.Select(x => x.Specification);
Commands.Fetch(r, remote.Name, refSpecs, new FetchOptions { Prune = true }, string.Empty);
var id = new Identity("name", "email");
var opt = new RebaseOptions();
var rebaseResult = gitRepo.Rebase.Start(
branch: gitRepo.Head,
upstream: gitRepo.Head.TrackedBranch,
onto: null,
id,
opt
);
I'm using filter with QueryBy to get the commits that I'm interested in.
// Set the filter
CommitFilter filter = null;
filter = new CommitFilter()
{
IncludeReachableFrom = "85494c32921c136cc3381fc14a3a20e08012c514",
ExcludeReachableFrom = "63c8cb9ed585c0f3b79b6e2efc067e254910f875"
};
// Get the commits
repo.Commits.QueryBy(filter)
The QueryBy will not return the 63c8cb9ed585c0f3b79b6e2efc067e254910f875 commit, it will return the commits between the two.
Is there a way to have the 63c8cb9ed585c0f3b79b6e2efc067e254910f875 commit included as well ?
Maybe there another way available that I can use to get to the previous 63c8cb9ed585c0f3b79b6e2efc067e254910f875 from the commit that came after 63c8cb9ed585c0f3b79b6e2efc067e254910f875 and is returned by the query ?
You can use parents of the Commit as list of commit pointers for your ExcludeReachableFrom filter.
Example:
var filter = new CommitFilter
{
IncludeReachableFrom = "824201fcb8d4fa79b0aafa7c5aea86643cdd118a",
ExcludeReachableFrom = repo.Lookup<Commit>("bcd85da0e287a3b404d12f8b666888962f692076").Parents
};
var commits = repo.Commits.QueryBy(filter);
foreach (var commit in commits)
{
Console.WriteLine($"{commit.Sha}");
}
Output:
824201fcb8d4fa79b0aafa7c5aea86643cdd118a

I want to retrieve commits from master first parent only using libgit2sharp, the equivalent command line statement is
git log --first-parent master --oneline
I know of the CommitFilter that I can use with QueryBy, like this
repo.Commits.QueryBy(new CommitFilter() { FirstParentOnly = true })
I'm getting commits on the branch that I'm currently on if I'm not on master. Can I limit the commit results to master, even when I'm on a different branch ?
I believe you are looking for the IncludeReachableFrom in the CommitFilter.
You might want to also use ExcludeReachableFrom at the same time to remove the commits from the branch that you are currently on...
using (var repo = new Repository("/Users/sushi/code/redux/playscript"))
{
var commitLog = repo.Commits.QueryBy(new CommitFilter() { FirstParentOnly = true, IncludeReachableFrom = "master" });
foreach (var commit in commitLog)
{
Console.WriteLine($"{commit.Sha}");
Console.ReadKey();
}
}
I'm trying to figure out how to get the commit log for a sub directory. According to this thread, it should work fine in libgit2sharp.
For testing I'm using a small repo, https://github.com/ornatwork/nugetpackages.git that has 8 total entries for the whole repository.
I cloned it locally in root c:/nugetpackages, from that folder I can do.
git log -- devbox
on the command line and I will get two commit entries for the /devbox sub directory as expected.
Sample Xunit test code to do the same using libgit2sharp
[Fact]
public void testSub()
{
// Extract the git commit history
using (var repo = new Repository(#"C:\nugetpackages"))
{
Trace.WriteLine("repo count=" + repo.Commits.Count());
// absolute path
IEnumerable<LogEntry> history = repo.Commits.QueryBy(#"C:\nugetpackages\devbox");
Trace.WriteLine("subdir count=" + history.Count());
}
}
I'm expecting count of 8 and 2, but this is what I get.
repo count=8
subdir count=0
What am I missing ?
Use a relative path from the repository's base diretory:
using (var repo = new Repository(#"/Users/sushi/code/sushi/Xamarin.Forms.Renderer.Tests"))
{
D.WriteLine("repo count=" + repo.Commits.Count());
IEnumerable<LogEntry> history = repo.Commits.QueryBy(#"AlarmSO");
D.WriteLine("subdir count=" + history.Count());
}
ref: FileHistoryFixture.cs
Update:
Follow up, is there a way to combine subdir with a filter, for example. CommitFilter filter = new CommitFilter(); filter.FirstParentOnly = true;
Not sure if this is what you are looking for... if not please in a new question, thanks.
using (var repo = new Repository(#"/Users/sushi/code/sushi/RealmJson"))
{
var subDir = "media";
var commits = repo.Commits.QueryBy(new CommitFilter { FirstParentOnly = true }).Where(
(Commit c) => c.Tree.Any(
(TreeEntry te) => te.Path.StartsWith(subDir, StringComparison.Ordinal)));
foreach (var commit in commits)
{
D.WriteLine($"{commit.Sha} : {commit.MessageShort}");
}
}
I'm currently trying to update my local repository from a remote one.
This works as long as I don't have any local changes in my files.
using (var r = new LibGit2Sharp.Repository(repo))
{
var options = new MergeOptions
{
MergeFileFavor = MergeFileFavor.Theirs,
};
var result = r.Network.Pull(localSignature, new PullOptions { MergeOptions = options });
}
I found that answer before: StackOverflow.
However, while trying this with the above code, it's just marking my repo as "Up2Date" (status of the result) instead of actually merging my local changes with the remote updates.
How can I actually achieve this?
