Very interesting question, could you please raise the issue in GitHub repository for the project.

We would need a bit more details about it, what you have in your SourceControl Class, and what do you expect.

But, be aware, that this feature was not completely implemented at the moment. It may not implement all the features available in Studio, due to some differences in architecture.

Permission denied issues come from a non-root environment configured for the latest few versions of IRIS. And, so, you don't have access to folders, out of access of user irisowner, which runs IRIS inside. This user has access to his home folder - /home/irisowner, and /usr/irissys, where IRIS installed. But you should know that anything created on a filesystem inside the container will disappear after its recreation. And it's how it supposed to work. If you need access from outside the container to created folder, or keep it save even when the container re-created, you have to bind some folder on your local filesystem inside the container, with --volume|-v option (do not forget to give permission to do it in docker settings).

I suppose, there is no way how to run Community Edition directly if you have so many cores, at least, yet. And at the moment, you can use Docker or virtualization, and Docker I would say preferable way.

<STORE> error happens due to the memory limit exceeded in the process. Since 2012.2 memory limit is set as 256MB per process by default, you can increase it in System Management Portal on page Memory and Startup

I do now what is nactive.

what do you expect from this tool?

Did you look at DBeaver or DataGrip?

After a brief look at the tif format, it found to be quite tricky to get ImageSize.

tif(folder, filename) {
#define READWORD $sconvert(fs.Read(2),"U2",endian)
#define READLONG $sconvert(fs.Read(4),"U4",endian)
#define WORD(%val) $sconvert(%val,"U2",endian)
#define LONG(%val) $sconvert(%val,"U4",endian)

  Set fs = ##class(%Stream.FileBinary).%New()
  Set fs.Filename = ##class(%File).NormalizeFilename(filename, folder)
  Set FileSize = fs.Size
  
  Set Width = 0, Height = 0

  Set Identifier = fs.Read(2)
  If Identifier=$Char(73,73) {
    Set endian = 0
  } ElseIf Identifier=$Char(77,77) {
    Set endian = 1
  } Else {
    Throw "Bad Format"
  }
  Set Version = fs.Read(2)

  Set IFDOffset = $$$READLONG
  
  Do {
    Do fs.MoveTo(IFDOffset+1)
    
    Set NumDirEntries = $$$READWORD
    For i=1:1:NumDirEntries {
      Set tag = fs.Read(12)
      Set TagID = $$$WORD($Extract(tag,1,2))
      Set DataType = $$$WORD($Extract(tag,3,4))
      If (TagID=256)||(TagID=257) {
        Set Value = -1
        If DataType=3 Set Value = $$$WORD($Extract(tag,9,12))
        If DataType=4 Set Value = $$$LONG($Extract(tag,9,12))
        Set:TagID=256 Width = Value
        Set:TagID=257 Height = Value
      }
    }
    Set NextIFDOffset = $$$READLONG
    Set IFDOffset = NextIFDOffset
    
    Quit:(Height>0)&&(Width>0)
  } While NextIFDOffset>0

  ZWrite Height,Width
}

There are many different types of applications. And Caché or nowadays IRIS is just a part of it. For any new applications, I would not recommend using ObjectScript as much as possible and use it as a Database if you need it to just store the data. Any simple application may become bigger in the future, so, having already something that will help with is a good idea. InterSystems some time already offers Community Editon version of IRIS, which is for free, without some of the features, and limited by the size of the Database. And for a simple application, 10GB looks enough. But depends on what do you mean by simple application. It may do some simple task but which will be heavy in the size of data.
