anyclone's Introduction

Hello there, I’m @replaysMike

I'm a full-stack developer, software architect and I’m interested mostly in C# and C embedded development - though I dabble a lot.

One of my biggest projects is 360 Replays where I designed and built a huge moving camera array.

I’m currently learning all the things! Lots of experience with security, design and crypto I'm always building something.

📫 I can be reached via my personal website at refactor.ca or here on GitHub. Open a pull request I have many projects!

anyclone's Issues

AutoMapper vs AnyClone

It is merely a question rather than a bug or issue.

Is AnyClone preferred over AutoMapper.Map<T, T>() method ? Without being too specific.

And being a little more; do you actually handle anytihing special around properties like ;

        [BsonId]
        public long Id { get; set; }

Comparing two complex object returns an exception

Hi. I have a fairly complex objects to compare. Its basically Dictionary<string, object>, where the number of keys inside dictionary is 23. Some are plain strings, some are Boolean, but some are StrokeCollection, List< CustomTypeDTO >, OtherCustomTypeDTO etc...you get the point, its all there 😄

I'm using FastDeepCloner currently to create snapshot for some of the properties that are collections, because AnyClone also throws exception, something like: "Type is ambiguous". So after the snapshot of some properties, the original object and the one with snapshot properties are compared using AnyDiff. I get the following exception:

Sequence contains no matching element

Change of license?

Howdy!

Would there be any chance of changing the license to MIT or some such? I'm in a situation where this library, so far, is the only one that seems to handle the deep cloning of a Swashbuckle.Application.SwaggerDocsConfig object.

Where I need to use it, however, is in a product that cannot be licensed under GPL, so the copyleft nature would in fact prevent me from using this.

I realise that this is likely too big a pain, but thought it worth asking.

Thanks!

overriding json ignore

I have some properties in my dto models which have json ignores tags on them bcz we dont need them in the db but we do need them on the client side. so that means when I created my backup object while editing I do need to copy these properties as well, so using this library can I override and hence also copy the properties tagged with json ignore? Thanks

some thing wrong in this example

    public class CBase<TKey>
    {
        public TKey Id { get; set; }
    }


    public class C3 : CBase<int>
    {
        public new int Id { get; set; }
    }

    public class C2 : CBase<int>
    {

        public C3 c3 { get; set; } = new();
    }

    public class C1 : CBase<int>
    {
        public C2 c2 { get; set; } = new();
    }

    public class CloneAndDiffTest : TestBase
    {

        [Fact]
        public void TestClone()
        {
            var org = Fixture.Create<C1>();
            var c1 = FastDeepCloner.DeepCloner.Clone(org);
            var c2 = AnyClone.CloneExtensions.Clone(org);// pst.MapClone();
            var diffs_0 = org.Diff(c1);
            var diffs_1 = org.Diff(c2);
    }
  }

Add support for multidimensional and jagged arrays

We need support for multidimensional arrays, currently not supported

Tests fail when run inside Blazor

Mike,

I would love to use this component in my Blazor-State component and thus eliminate the developer burden of creating deep Clone methods.

It works great when I use it on Server Side Blazor (SSB). But I get an exception when running Client Side Blazor (CSB).

CSB runs under mono whereas SSB runs dotnet core. I spent about 6 hours pulled in AnyClone and TypeSupport source. Moved all the tests cases into a Blazor Page.

turns out that in public ExtendedProperty(PropertyInfo propertyInfo) for Generic List and the Capacity Property the following returns null in CSB

_propertyInfo.GetGetMethod(true)

and in SSB it returns the appropriate MethodInfo.

Have you run your tests against a mono build?

Any suggestions?

This looks like it could be an awesome solution for my use case.

Fill free to reach out to me on Discord (StevenTCramer
#9010) or Twitter (StevenTCramer) if more convenient for you.

Thanks!

Is it possible to clone properties with complex constructor?

How to clone a class that has a property of a type that only has a complex constructor?
In Json.Net this is possible using the [JsonConstructor] attribute on the constructor that has to be used

Clone references

I have and object like that:

Person (string Name, Person subp1, Person subp2)

If i create

P1=new Person ("p1",null,null)

and then

P2= new ("p2",P1,P1)

and i clone this P2 object as P3, its very strange but first child subp1 creates a new object but subp2 gets linked to the original.

P3.subp1 memory address is different of P2.subp1 "BUT" P3.subp2 and P2.subp2 have the same memory address, so any changes on the subp2 original gets replicated on the cloned instance and viceversa.

clone System.Text.Json.Serialization.JsonSerializerOptions throws exception.

trying to clone JsonSerializerOptions in dotnet core 3 throws exception.

JsonNamingPolicy.CamelCase is not an enum but some crazy object.

using System.Text.Json.Serialization;

    public void ShouldCloneJsonSerializationOptions()
    {
      var jsonSerializerOptions = new JsonSerializerOptions
      {
        PropertyNamingPolicy = JsonNamingPolicy.CamelCase
      };

      JsonSerializerOptions clone = jsonSerializerOptions.Clone();
      clone.PropertyNamingPolicy.ShouldBe(JsonNamingPolicy.CamelCase);
    }

Cloning static readonly fails in .Net Core 3.0

I tried to clone a NodaTime.Period and it throws this exception: System.FieldAccessException: Cannot set initonly static field '<Zero>k__BackingField' after type 'NodaTime.Period' is initialized.

Does not deep copy mutable value types

Hi fellow deepcopy developer, when I ran your library against my unit tests (I was actually looking to benchmark it against the purely reflection based approach) an issue popped up: AnyClone v1.1.6 does not deep copy value types that contain references to mutable classes. Here's the unit test:

        [TestMethod]
        public void Copy_DeepCopiesMutableFieldsOfValueTypes()
        {
            // Tuple itself is a mutable valuetype, MySingleObject is a class
            var a = new Tuple<MySingleObject>(new MySingleObject());
            var b = AnyClone.CloneExtensions.Clone(a);
            Assert.AreNotSame(a.Item1, b.Item1);    // this assert fails
            Assert.AreEqual(a.Item1, b.Item1);
            Assert.AreEqual(a, b);
        }

In other words this will result in two copies of Tuple that share the same 'MySingleObject' instance.
