I'm trying to figure out how I'd implement the equivalent of git status using libgit2sharp. All of the collections on Index (Modified, Staged, Unstaged) all throw NotImplementedException. When there are files in the index, it seems like they are always in the "NotModified" state.

Am I missing something or is the functionality not there yet?

Is there any way to update the working directory to a specific commit id or branch name? Basically the equivalent of "git checkout {branch name}" or "git checkout {somesha1}",

Currently there doesn't seem to be a way to do a pull, or even a separate fetch-merge operation. Will be nice, and quite useful, to have this...

One thing I find a bit quirky is that if your repo is in c:\foo, then you have to pass "c:\foo.git" when creating a Repository. Would it make sense to add some smart to the Repository ctor to handle both cases? The .git folder is sort of a git implementation detail that the API consumer should not have to deal with.

The logic would all be in LibGit2Sharp and not affect LibGit2. Could be as simple as saying that if the passed in folder contains a .git folder, then use that instead. And if it's that simple, I'll sign up to do it :)

Hardcoded paths containing the file seperators are considered bad!
The PathSeperator on Windows and Unix differ and since there is already functionality in the .NET framework itself solving this problem -> we should be utilizing that functionality to make it platform independent.

Hardcoded paths containing \ are so yesterday :P
The kewl libs nowadays use Path.Combine.

Hey guys, does libgit2sharp have any way to create commits?

Hi everyone,

I think you have a bug in your Index.Unstage() implementation.

The Unstage method will call Index.RestorePotentialPreviousVersionOf() which will call AddToIndex().

I think this is not what you want.

Regards.

I've successfully created a Repository:

UriAgility gitUri = UriAgility.Parse("~/App_Data/SCommunity/wikiRepo/.git");
if (!gitUri.FileInfo.Directory.Exists)
Repository.Init(gitUri.FileInfo.DirectoryName);

using (var repo = new Repository(gitUri.PhysicalPath))
{
HttpContext.Current.Response.Write(string.Format("Working directory: {0}
", repo.Info.WorkingDirectory));
HttpContext.Current.Response.Write(string.Format("Repository path: {0}
", repo.Info.Path));

...
What do I put here to Add file to the repository?
What do I do to get the file once it is in?
How do I get the diff between versions?
...
}

Tests used to pass on Windows against Mono 2.10 and .net 3.5.

Since commit 52de337d, they no longer pass against Mono 2.10. A DllNotFound-like exception is raised.

Some documentation:

• MSDN Loadlibrary
• Mono on "Interop with Native Libs"

In the constructor of Repository, commits, branches, refs and tags are all loaded. In my case it makes LibGit2Sharp 4x slower than GitSharp. Please consider apply lazy loading everywhere to load data only needed. e.g.

    public ReferenceCollection Refs
    {
        get 
        {
                if (refs==null) refs = new ReferenceCollection(this); 
                return refs; 
        }
    }

Listed below is the test case.

    [TestMethod()]
    public void RefsTest()
    {
        var tempFolder = ".......";

        Stopwatch w = new Stopwatch();
        w.Start();

        for (int i = 0; i < 5000; i++)
        {
            var repository = new LibGit2Sharp.Repository(tempFolder);

            foreach (var r in repository.Refs)
            {
                var k = r.CanonicalName;
            }
            repository.Dispose();
        }

        w.Stop();
        Console.WriteLine("Time elapsed: {0}", w.Elapsed);
    }

Thanks,

Hi @ALL,

lets say we have the following workflow:

1. Adding a file to the repository
2. Commit
3. The file will be deleted in the working copy (not with Index.Remove())
4. How to get the repository in sync with the current working copy?

If you call Index.Remove() on an already deleted file you will get an exception.

I made some changes but my changes will result in some failing tests afterwards... So... How to remove an already deleted file?

[Update]
The above mentioned changes can be seen here

Hi ! Unit tests are failing on x64 system. Switching to x86 resolves this issue.

This would help ensuring that LF line endings are being committed into the repository without compelling the contributors to change their local configuration.

@projectkudu relies on git log --all to page through the commits. A very first draft implementation is available with PR #61.

Notable new usages are covered there:

• CanEnumerateCommitsFromMixedStartingPoints
• CanEnumerateCommitsFromATag
• CanEnumerateAllCommits

I'd like to make this feature available for the next release (v0.5). However in order to be as complete as possible I'd like some feedback about how should the feature react when dealing with the following:

• A reference which points to an objectId/Sha which doesn't exist in the repository
• A tag which points to a tree or a blob

@davidfowl, @davidebbo, @tclem, @xpaulbettsx, @henon Should this throw? Should this be detected as a weirdo use case and silently ignored? Can you think of other strange configurations that should be dealt with?

This is a cross post from http://stackoverflow.com/questions/6313203/unable-to-load-dll-git2-dll-the-specified-module-could-not-be-found/6315033#6315033

I'm using VS2008 and had to create a new solution since the solution and csharp files are .Net 4.0. As far as I could tell its just default parameters that I had to create overloaded methods to handle them to convert to 3.5.

I've copied the git2.dll into every bin folder and have linked it and set copy if newer, but still get the "Unable to load DLL 'git2'" error for

Repository.cs
Line 27: var res = NativeMethods.git_repository_open(out handle, PosixPathHelper.ToPosix(path));

I'm trying to use the library in a ASP.NET website via a custom-controls library.

If we want to allow building on a Mono/Linux platform, the Dos commands in pre/post build events may not play nicely. Maybe should we rather favor a base test class in charge of checking and setting up the test environment.

This base class would be responsible of:

• Making sure the resource are copied and available to the tests
• Renaming the "dot_git" folder into ".git" (and replace this piece of code)

        [DllImport(libgit2)]
        public static extern int git_reference_listall(git_strarray* array, RepositorySafeHandle repo, GitReferenceType flags);

        [DllImport(libgit2)]
        public static extern int git_tag_list(git_strarray* array, RepositorySafeHandle repo);

        [DllImport(libgit2)]
        public static extern void git_strarray_free(git_strarray* array);

Consider changing "git_starray*" "out git_strarray". This will make libgit2sharp run on mono 2.8+.

I would like to stage a file with a full path. I have a failing test showing this doesn't work (cbilson/libgit2sharp@d849ca7b93538d85cc4a). I thought maybe using the posix helper on the path would fix it (cbilson/libgit2sharp@aae13a51b75d98a20b5c), but it didn't.

Any ideas? Should I just not try to do this? Thanks!

Bind libgit2's methods

GIT_EXTERN(int) git_tag_create_f(
        git_oid *oid,
        git_repository *repo,
        const char *tag_name,
        const git_oid *target,
        git_otype target_type,
        const git_signature *tagger,
        const char *message);

GIT_EXTERN(int) git_reference_create_oid_f(git_reference **ref_out, 
                         git_repository *repo, const char *name, const git_oid *id);

GIT_EXTERN(int) git_reference_create_symbolic_f(git_reference **ref_out, 
                        git_repository *repo, const char *name, const char *target);

Change signature of the Create() methods of TagCollection into

public Tag Create(string name, string target, Signature tagger, 
             string message, bool allowOverwrite = false);

public Tag Create(string name, string target, bool allowOverwrite = false);

Change signature of the Create() methods of RefCollection into

public Reference Create(string name, string target, bool allowOverwrite = false);

public Reference Create(string name, ObjectId target, bool allowOverwrite = false);

@davidebbo published a very interesting nuget package for SqlCe. Sources are available there.

This package includes both the 64 an 32 bits versions of the native binaries. The .Net assembly detects the platform it's being run on and dynamically load the correct binary.

This would be a very nice feature for LibGit2Sharp.

When using Repository.Init I realized it doesn't make the .git folder hidden on windows (not sure what it does on other OSes). Is this by design or just something that's missing?

There is empty Tree class, and no bindings in native methods. Let me implement this feature by myself.

As stated by @davidebbo and @davidfowl

Earlier versions of ‘nuget pack’ built the solution, while the newer ones expect it to be built already

If you want to build the package from a project and have it build then you have to use the -build switch. Alternatively, you can use >the new workflow to build a package from a project:

• Install-Package NuGetPowerTools
• Enable-PackageBuild ProjectName

That will setup your project to build a package as well as well as a symbols package on build.

Currently LibGIt2Sharp throws when reading from a non existent configuration setting

Proposal is to make the following tests pass:

Assert.AreEqual("tclem rulz", repo.Config.Get<string>("unittests.ghostsetting", "tclem rulz"));
Assert.AreEqual(true, repo.Config.Get<bool>("unittests.ghostsetting", true));
Assert.AreEqual(42, repo.Config.Get<int>("unittests.ghostsetting"), 42);
Assert.AreEqual(17, repo.Config.Get<long>("unittests.ghostsetting"), 17);

It is not exactly an issue, just small inconvenience in checking test greenness.

I have user's environment variable HOME and my global .gitconfig is located there. libgit2 correctly determines that and Configuration.Set writes values there. On the contrary ConfigurationFixture.CanSetGlobalStringValue test assumes that global settings are located at Environment.SpecialFolder.MyDocuments folder and thus gives false fail (and strange file c:\Users\idanilov\.gitconfig as a result).

Hello,

i´m using the libgit2sharp in a multithreaded win32 application. Two days ago i got some strange application behavior. My App crashed with error Code "0xC0000417" (STATUS_INVALID_CRUNTIME_PARAMETER). And it took me some time to track down the source of this error. It was caused by a threaded access to libgit2sharp.
To solve this error i built my own libgit2 dll (git2.dll) with enabled THREADSAFE flag and used this dll to rebuild the libgit2sharp dll.

Is it the case that the shipped git2.dll is build without the THREADSAFE flag ?

When calling Repository.Init, it does not create a .git/config file. This seems to throw off some git client. For instance, it causes GitSharp to fail when trying to open the repo.

Looking in more details, it looks like the minimal settings that makes GitSharp happy is:

[core] repositoryformatversion = 0

Should libgit2sharp be creating the config file when creating the repo?

I'm running Windows 7 x64.

I'm unable to retrieve any configuration settings from the Configuration object when my .gitconfig is a symbolic link (made from mklink). Otherwise it works fine.

Great work so far on the project, nice clean API. Can't wait for pull/push implementation! :)

Cheers,
Thiru

LibGIt2Sharp is published as a NuGet package. In order to ease the consumer debugging experience, sources and pdbs should be published at symbolsource.org.

For further information, refer to

• @davidebbo's post
• This thread which gives some hints about the expected symbolsource package structure

Building on top on nulltoken/libgit2sharp@e12b358, running build.nuget.package.cmd should produce the symbolsource package as well.

We have a big freaking problem.
time_t on 32bit linbux is 32bits long and you are using long, I guess, 64bit windows?
I think it is generally 64bit long on windows.
It is possible to determine the environment on runtime and do a workaround, but I first have to know how long it time_t on windows 32bit is.

Hi @ALL.

I'm searching for a method that will return the last commit that affected a given file.

I looked through the API but I did not find a method that seems to do it.

First question: Was the solution overlooked?
Second question: How to get the last commit?

Thanks.

Hi,

I plan to use libgit2sharp in the backend to serve bare git repositories. The idea is to allow clients to do clone requests from the server using smart http. Is this supported with this library? If so what would the code look like?

Is it possible in the constructor of Repository if repo not found on given path, automatically try path + "/.git", and then path + ".git", maybe even parent directories, before throw exception?

thanks,

yysun

Issue #39 raised the fact that MSVCR100.dll is required on some system. Therefore, It has to be included as a dependency

• Of the project
• Of the NuGet package

Once again, @davidebbo already solved this! See here.

git.exe works fine when you re-initialize an existing repository but libgit2sharp (or libgit2) fails.

Hi,
How to, with a specific commit, get a list of modified files?

Thanks

Repro steps:

Create a new git repository:

mkdir folder
cd folder
git init

Create a repository instance and try to list commits.

var repo = new Repository(@"C:\dev\folder\.git");
foreach (var c in repo.Commits) {
    Console.WriteLine(c.Id);
}

Expected:

Empty commit collection

Actual:

Null reference exception

I actually dug a little deeper into why it throws. It seems that this line throws (CommitCollection.StartingAt):

return new CommitCollection(repo) { sortOptions = sortOptions, pushedSha =   reference.ResolveToDirectReference().Target.Sha };

ResolveToDirectReference() returns null since the reference is the head which doesn't point to any commits by default.

I like to use libgit2sharp nuget package in Windows Azure Web/WorkerRole application. But in Azure Roles support x64 code only, I can't use 32bit dll.

Add x64 binary to nuget package.

Hi! I've found a strange issue. Enumerating tag in repository git://github.com/spdr870/gitextensions.git gives 81 nulls and 1 real tag. All other tags are visible in repo.Refs as commits.

Code to list tags:

        const string path = @"x:/git/ge/.git";
        using (var repo = new Repository(path))
        {
            int found = 0;
            foreach (var tag in repo.Tags.Where(t => t != null))
            {
                Console.WriteLine(tag.Name);
                found++;
            }

            Console.WriteLine("Found {0} of {1} tags.",found, repo.Tags.Count());

        }

sample code is available here - [email protected]:gorbach/libgit2sharp.git (branch git-log)

Repro steps:

1. clone this project (libgit2) locally
2. Write the following code:

var r = new Repository(@"C:\dev\github\libgit2sharp\.git");
foreach (var c in r.Commits.ToList()) {
    Console.WriteLine(c);
}

It blows up with:

Unhandled Exception: System.ApplicationException: An error was raised by libgit2

Bind libgit2's methods

GIT_EXTERN(int) git_reference_rename(git_reference *ref, const char *new_name);

GIT_EXTERN(int) git_reference_rename_f(git_reference *ref, const char *new_name);

Add following method to ReferenceCollection

public Reference Move(string oldName, string newName, bool allowOverwrite = false);

I saw on the Wiki page that the design goal of LitGit2Sharp is to provider a high level wrapper to, but not be a 1:1 mapping of the libgit2 C API. I would like to suggest you split the LitGit2Sharp into two libraries. One only contains P-Invoke functions and unsafe helpers. The other one for high level wrappers.

Alternatively, maybe you can make P-Invoke functions and unsafe helpers public, so that we can call them directly.

Thanks,

Hi.

I'm missing a Date/Time Property on the Commit class. There's the git_commit_time in libgit2 but it seems The libgit2sharp binding doesn't make any use of it. Or is there another special way to get the DateTime when a commit was added to the repository?

Hi,

I have an example listed below. Can you see any problem from it?

    public IEnumerable<string> GetRefs()
    {
        var tempFolder = ".....";

        using (var repository = new LibGit2Sharp.Repository(tempFolder))
        {
            return from r in repository.Refs
                       select r.CanonicalName;
        }
    }

    [TestMethod()]
    public void GetRefsTest()
    {
        var refs = GetRefs();
        foreach (var r in refs)
        {
            Console.WriteLine(r);
        }
    }

The test method GetRefsTest will throw exception: System.ObjectDisposedException: Safe handle has been closed.

Currently POSIX path handling is not consistent across various APIs. For example, paths passed into and returned from the index are still in POSIX.

I have two changes in mind that might help with this:

• A PosixPath class with implicit cast to/from string to make explicit where the path must be in POSIX
• A PosixMarshaler (likely a subclass of Utf8Marshaler) to let the appropriate NativeMethods use PosixPath

Thoughts?

Proposal to add the following to Branch:

• bool IsTracking { get; }
• Branch TrackedBranch { get; }
• int AheadBy { get; }
• int BehindBy { get; }

Which would satisfy the following:

Branch branch = repo.Branches["test"];
branch.IsTracking.ShouldBeFalse();
branch.TrackedBranch.ShouldBeNull();
branch.AheadBy.ShouldEqual(0);
branch.BehindBy.ShouldEqual(0);

Branch master = repo.Branches["master"];
master.IsTracking.ShouldBeTrue();
master.TrackedBranch.ShouldEqual(repo.Branches["refs/remotes/origin/master"]);
master.AheadBy.ShouldEqual(1);
master.BehindBy.ShouldEqual(2);

(assuming master has one commit origin/master doesn't and origin/master has two commits master doesn't)

For a repository with remote branches, enumerating repository.Branches throws:

System.ArgumentException : 'refs/remotes/origin/master' is not a valid Sha-1.
