Problem with MacOSX

[oddball]

I got a test case that works well on Windows, and with Mono on Linux, but it fails with Mono on MacOSX.
Test framework used is Nunit

        [Test]
        public async Task TestMongo2Go()
        {
            var tmpDir = System.IO.Path.GetTempPath();
            MongoDbRunner _mongodb = MongoDbRunner.Start(tmpDir);
            var _mongoClient = new MongoClient(_mongodb.ConnectionString);
            IMongoDatabase db = _mongoClient.GetDatabase("unittest");
            var role = new Role { Name = "ALL PERMISSIONS", PermissionTypes = new List<string> { "ALL PERMISSIONS", "READ_ALL" } };
            await db.GetCollection<Role>("role").InsertOneAsync(role);
            var user = new User { Name = "unittest", PersonalNumber = "123", RoleIds = new List<ObjectId> { role.Id } };
            await db.GetCollection<User>("user").InsertOneAsync(user);
            var users = await db.GetCollection<User>("user").Find(u => true).ToListAsync();
            Assert.AreEqual(1, users.Count);
        }

Stack trace is:

TestMono.TestMongo2GoUser
System.TimeoutException : A timeout occured after 30000ms selecting a server using CompositeServerSelector{ Selectors = WritableServerSelector, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }.

No firewall and ping localhost works
Any suggestions would be appreciated

No Mac here. But I can investigate as soon as my first Mac arrives. (hopefully sooner than later)

[JohannesHoppe]

Please test this again with Mongo2Go 2.2.1 which will be released soon!

[JohannesHoppe]

I pushed v2.2.1 to nuget.org. Could you please test it?

[oddball]

Sadly no difference when updated to 2.2.1 .
But I was before on 2.1.0 and I can see someone else leaving a comment "dont update to 2.2.0". Going to investigate tomorrow.
However, I did do a git pull on mongo2go repo and ran

dotnet restore
dotnet build
dotnet test src/Mongo2GoTests/Mongo2GoTests.csproj

With the result

Total tests: 29. Passed: 29. Failed: 0. Skipped: 0.
Test Run Successful.
Test execution time: 14.3335 Seconds

On my macbook

Turns out I am forced to use
targetFramework="net461"
I dont suppose this 2.2.1 will be backported?

[JohannesHoppe]

I could do that.

The main new features are:

1. uses temporary directory instead of C:\data\db -- optional, because this can be also changed by method parameter
2. the bugfix which is making the binaries executable for MacOS and Linux

Let's see if you need that bugfix. Could you please install Mongo2Go 1.1.0 and make the binaries executable (chmod+x) by hand? If that works, I will backport that change to the 1.x branch.

[oddball]

chmod +x ../packages/Mongo2Go.2.1.0/tools/mongodb-osx-x86_64-3.2.7/bin/mongo*

made no difference for me, but

rm ../packages/Mongo2Go.2.1.0/tools/mongodb-linux-x86_64-3.2.7/bin/mongod

resulted in

System.IO.FileNotFoundException : Could not find file "packages/Mongo2Go.2.1.0/tools/mongodb-linux-x86_64-3.2.7/bin/mongod"

Which leads me to believe that that it does not resolve to osx bin when on mac. Sadly moving the osx bin files to the linux folder results in the usual

System.TimeoutException : A timeout occured after 30000ms selecting a server using CompositeServerSelector{ Selectors = WritableServerSelector, LatencyLimitingServerSelector{ AllowedLatencyRange = 00:00:00.0150000 } }. Client view of cluster state is { ClusterId : "1", ConnectionMode : "Automatic", Type : "Unknown", State : "Disconnected", Servers : [{ ServerId: "{ ClusterId : 1, EndPoint : "Unspecified/localhost:27018" }", EndPoint: "Unspecified/localhost:27018", State: "Disconnected", Type: "Unknown", HeartbeatException: "MongoDB.Driver.MongoConnectionException: An exception occurred while opening a connection to the server. ---> System.Net.Sockets.SocketException: Connection refused

I am not sure why 2.1.0 works with a package.config on Windows and Linux like below, I am not using 1.10

<packages>
...
  <package id="Mongo2Go" version="2.1.0" targetFramework="net461" />
....
</packages>

I can confirm this seems to be related to the target framework (netcoreapp2.0 vs net461) rather than the OS under which Mongo2Go is used.
I.e., also when targeting netcoreapp2.0 under Windows Mongo2Go seems to cause the program to freeze (as soon as the program attempts to access MongoDB via the c# driver). Also the mongod process (launched by Mongo2Go) becomes inaccessible, i.e you cannot even connect to the database using other tools such as NoSql Manager for MongoDB. As soon as the c# application is killed the mongod process again is accessible using other tools.

However when targeting net461 under Windows everything works fine without any problems.

[JohannesHoppe]

I'm confused. Does anybody has a working solution?

[oddball]

I am no longer in position to try this on Mac. Cant help anymore.

[JohannesHoppe]

I was able to successfully run dotnet test src/Mongo2GoTests on my mac with .NET core 2.1.301.
