Pull Request Overview

This PR removes deprecated Dynamo nodes that were marked with [NodeObsolete] in version 2.19.5 to clean up the codebase before the 3.0 release. The removal includes obsolete methods from Excel, FileSystem, String, and Analysis libraries along with their associated test files and documentation.

Removed 17 deprecated methods across Excel, FileSystem, String, and Analysis classes
Deleted entire obsolete Analysis data classes (SurfaceData, PointData, VectorData)
Removed corresponding test files and XML documentation entries

@jasonstratton Some regressions to fix(remove) as well

are you finding that this is just flaky? Or does it fail locally as well?

It did fail locally. I marked it as [Ignore] in order to get the tests to pass and address the test shortly. I was not sure about how to replace the .dyn file right off. The test appears to expect an obsolete node and expects to see a popup. Maybe it is just as simple to replace the node in the graph with another that is still deprecated.

mjkkirschner · 2025-10-15T04:12:15Z

src/Libraries/CoreNodes/FileSystem.cs

-        [SupportedOSPlatform("windows")]
-#endif
-        [NodeObsolete("ReadImageObsolete", typeof(Properties.Resources))]
-        public static Color[] ReadImage(string path, int xSamples, int ySamples)


so I think that in addition to removing these methods it's probably good to:

as you've already done clean up the migration tests, I think you can just remove the old nodes from the graph - they're just not going to be migrated anymore. If we had the time it might make sense to see if we could migrate to something else - for example in this case there is the Image class - but it's not clear if auto migrating will be useful, it wasn't done when the node was obsoleted so maybe it doesn't make sense to do now with limited context for each node.

cleanup the migrations.xml files. If you search for the name of the node you'll find them - for example: https://github.com/DynamoDS/Dynamo/blob/master/src/Libraries/CoreNodes/DSCoreNodes.Migrations.xml#L13

Not sure. The resource string does say "Use File.FromPath -> Image.ReadFromFile -> Image.Pixels nodes instead" we could try to add a migration that does that
a. That reminds me to remove the obsolete resource strings

Thank you for that. I was unaware of the migrations.xml file

src/Libraries/Analysis/PointData.cs

-    /// A class for storing structure point analysis data.
-    /// </summary>
-    [IsVisibleInDynamoLibrary(false)]
-    public class PointData : IStructuredData<Point, double> //, IGraphicItem


so to be pedantic... this class and the other analysis classes were not actually marked obsolete... someone could still be using them without using the nodes ( I have no idea who that person would be or why)... the SAFEST thing to do is to keep the classes around and mark them obsolete. I will let you make that judgement call.

I did consider that and thought the original intent was so that the node would not be used, which was equivalent to being made obsolete. But I guess if it was in a graph, the user would not see an obsolete message and take and action.

If I were to restore it and mark it as obsolete, would you happen to know what the action the graph author should take?

what I meant, if it was not clear, is that the methods were marked obsolete, but the class was not. Someone could be using the class from c# or python because it was public.

If you just restore the class, not the methods and mark it as obsolete it should not be visible. I don't think theres any action anyone needs to take.

I do see that this class implements an interface and maybe it's not possible to remove the methods without removing the class anyhow because of compiler errors - in that case - I would not worry about it.

I do think it's worth being careful when differentiating between classes and members being marked obsolete.

    /// </summary>
    public static class String
    {
-        // It has been moved to String.FromObject UI node, which is compiled 


any idea what this comment was intending and if it was done?

I don't know the intention or whether it was done. I guess I should not have assumed. I will research.

oh man... I don't think this change comes from your PR ... this seems to have something to do with recent changes to codeblock UI...

@zeusongit is this intentional that such large amounts of DS code ends up duplicated in the description like this?

hmm...seems weird, and not intentional, to have this move to description, where do you think the change is coming from?

Oh, that's interesting. I just updated the graph so the test would pass, but I did not look into the contents of the .dyn file.

I followed the ReadTextObsolete resource string instructions and replaced FileSystem.ReadText with File.FromPath -> File.ReadText nodes

I think it's coming from the changes to codeblock that set the output name based on the variable name / value.

mjkkirschner · 2025-10-15T04:21:29Z

I think there are other resource strings (like the node obsolete messages) that need to be cleaned up, and since they are now stored in the repo (no comment on this) - I think that should all be cleaned up now as well for all languages, not just en-us.

jasonstratton · 2025-10-15T04:48:31Z

Yeah, I noted the resource strings in an earlier comment and made a note to remove them. I did not think about removing from the other languages. So I'll make a not eof that as well.

I might be wrong about that. @zeusongit can you fill us in on the proper way to update resource strings these days?

We just need to remove/update resource strings for en-US and the localization job should take care of the rest of the locale(s).
