Can you post the stack trace when this happens?

from fsharp.data.

ibrahim324 avatar ibrahim324 commented on May 28, 2024

this is the complete error message (copied from fsi):

System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.
   at System.Text.StringBuilder.ToString()
   at FSharp.Data.Runtime.BaseTypes.XmlElement.Create(TextReader reader) in D:\a\FSharp.Data\FSharp.Data\src\FSharp.Data.Xml.Core\XmlRuntime.fs:line 59

   at System.Reflection.MethodBaseInvoker.InvokeWithNoArgs(Object obj, BindingFlags invokeAttr)

Any other way to retrieve info about the error?

Thanks! In this case it seems the size of the string is too big, as this is failing with the internal StringBuilder used in the XML Reader. Are you running in a 32-bit process?

@cartermp No, I have not configured fsi in any way. I'm running on MacOS if that makes a difference.

Does it matter if the source file encoding is UTF8 or UTF16 ?

from fsharp.data.

ibrahim324 avatar ibrahim324 commented on May 28, 2024

@Thorium Can you point to where I should set the encoding? I tried the following:
let text = File.ReadAllText(path, Encoding.UTF32)
which didn't work, unfortunately. UTF16 wasn't available either.

Thorium avatar Thorium commented on May 28, 2024

I meant if you have the file as XML, if it's UTF16 then consider converting it to UTF8 to use less memory, e.g. Notepad++ tells you:
image

@Thorium Hi, I just opened it in Notepad++; The file was encoded in UTF-8 to begin with.

Try using fsiAnyCpu - fsi runs 32-bit by default

from fsharp.data.

ibrahim324 avatar ibrahim324 commented on May 28, 2024

@dsyme That doesn't seem to be the issue - i ran the script within Rider, which is anycpu by default as I checked. I also ran a console program, but it's still an OutOfMemoryException.
