Problem with System.Memory resolution in 6.0.101 using System.Text.Json #2642

Closed marklam closed 2 years ago

marklam commented 2 years ago

Description

Using System.Text.Json from fake-cli 5.21.0 under dotnet 6.0.101 produces an error concerning ReadOnlyMemory<_>

Repro steps

dotnet fake build -f broken.fsx where broken.fsx is:

#if FAKE
#r """paket:
    source https://api.nuget.org/v3/index.json
    storage: none
    nuget System.Text.Json
    //"""
#endif

open System.Text.Json

let parseTools (json : string) =
    use toolManifestDocument = JsonDocument.Parse(%json)
    toolManifestDocument.RootElement.GetProperty("tools")

Expected behavior

Nothing in this case, but without the crash.

Actual behavior

The last restore is still up to date. Nothing left to do.
Script is not valid:
        unknown (1,0)-(1,0): Error FS0193: The module/namespace 'System' from compilation unit 'System.Runtime' did not contain the namespace, module or type 'ReadOnlyMemory`1'
        c:\temp\script\broken.fsx (12,31)-(12,56): Error FS1109: A reference to the type 'System.ReadOnlyMemory`1' in assembly 'System.Runtime' was found, but the type could not be found in that assembly
        c:\temp\script\broken.fsx (13,4)-(13,48): Error FS0072: Lookup on object of indeterminate type based on information prior to this program point. A type annotation may be needed prior to this program point to constrain the type of the object. This may allow the lookup to be resolved.

Known workarounds

None currently

@marklam I have tried your example with the new FAKE runner release 5.21.1 and it ran successfully. I have added a global.json file beside the script to force net 6.0.101 as you specified. Please note that I had to change the call for parse since it seems the method signature has changed in net 6.0.101, please see This is the script I test with:

#if FAKE
#r """paket:
    source https://api.nuget.org/v3/index.json
    storage: none
    nuget System.Text.Json
    //"""
#endif

open System.Text.Json

let parseTools (json : string) =
    let options =  new JsonDocumentOptions(AllowTrailingCommas = true)
    use toolManifestDocument = JsonDocument.Parse(json, options)
    toolManifestDocument.RootElement.GetProperty("tools")
marklam commented 2 years ago

There was a stray '%' in my repro case, but it didn't seem to mind the missing options parameter. It's possibly dependent on the ReadOnlyMemory<char> vs string type resolution, so I'm attaching a zip which has the Fake script ("broken.fsx") and the same thing in fsi syntax ("not-a-fake-script.fsx"), along with a global.json, the fake lock file and the output when I run it ("log.txt"). I've also added a global.json just in case that was a factor.

The fake script should read:

#if FAKE
#r """paket:
    source https://api.nuget.org/v3/index.json
    storage: none
    nuget System.Text.Json
    //"""
#endif

open System.Text.Json

let parseTools (json : string) =
    let opt = JsonDocumentOptions()
    use toolManifestDocument = JsonDocument.Parse(json, opt)
    toolManifestDocument.RootElement.GetProperty("tools")

And the output I get is:

C:\temp\brokenscript>dotnet --version
6.0.101

C:\temp\brokenscript>dotnet fsi not-a-fake-script.fsx

C:\temp\brokenscript>dotnet fake build -f broken.fsx

I tried the sample you provided and it ran successfully. Following is the output I got:

The last restore is still up to date. Nothing left to do.

Can you please provide the output of dotnet --info and dotnet fake -vv build -f broken.fsx?

That's very odd. Here's the info you requested: dotnet --info

Inspired by that debug output, I cleared all my nuget packages from C:\Users\Mark.nuget\packages, restored everything etc, and it fixed it. I guess it was just a case of doesn't work on my machine!

Sorry to have wasted your time with my broken config!

If you look at the reference assemblies, they are from Netstandard.Library. So FAKE runner defaulted to using Netstandard2.0 reference assemblies instead of Net6. "-r:C:\Users\Mark\.nuget\packages\netstandard.library\2.0.0\build\netstandard2.0\ref\System.Numerics.dll";

When adding and removing the global.json file, you need to delete the FAKE cache directory to re-compile

marklam commented 2 years ago

Is it by design that without a global.json the reference assemblies are used instead of .net6 ?

yazeedobaid commented 2 years ago

Yes, previously FAKE runner was using reference assemblies from this library Netstandard.Library version 2.0.3. In that case, any packages that target Net 5 or above will not work with the FAKE runner, since it also pins its execution context to Netstandard2.0. We have updated the runner to support Net 6 since it is the next LTS release of DotNet. So, to activate the Net 6 reference assemblies, you need to have a global.json file that specifies a Net 6 SDK. Otherwise, the runner will default to Netstandard reference assemblies.

I see now, that's very helpful. Thanks again for your time!
