On my list of things to figure out: how to force fsck with opensuse Tumbleweed on Raspberry Pi 3

Posted by jpluimers on 2020/09/11

Hopefully the below links will eventually get me further in figuring out how to force fsck with opensuse Tumbleweed on Raspberry Pi 3.

For now, I just reinstalled an SD card (my Mac didn’t support the file systems and I did not have time and equipment with me to mount it to another opensuse based device).

FreePascal downloads I used to get Web Service Toolkit to compile since the Delphi WSDL importer has braindead include support

Posted by jpluimers on 2020/09/11

The Delphi WSDL importer maintenance has been in dormant mode for a long while, which means it still barfs on WSDL include directives.

In the day and age of REST and gRPC, I don’t think it will get any love soon.

Related bug entries are for instance RSP-18630: WSDL generate bad code and RSP-17321: “Import WSDL” generates invalid code without explanation of problem are examples of this, and I’m sure that QC had more if it were still alive; I could find these in the WayBack machine:

The problem manifests itself when the WSDL file includes one or more XSD files. The generated code will contain a section like this:

  // ************************************************************************ //
  // The following types, referred to in the WSDL document are not being represented
  // in this file. They are either aliases[@] of other types represented or were referred
  // to but never[!] declared in the document. The types from the latter category
  // typically map to predefined/known XML or Embarcadero types; however, they could also 
  // indicate incorrect WSDL documents that failed to declare or import a schema type.
  // ************************************************************************ //

Further below is a series of commented out types, all starting with a ! end ending in a column with the namespace of those types.

Searching for the first line gives numerous examples as far back as Delphi 7, for instance:

Based on those, I think the reason is that the WSDL importer fails on <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document" /> which is quite common in the real world.

I did not want to pursue manually modifying the WSDL file, or manually generating the types as the WSDL and XSD files were prone to changes and manual steps would make the re-import process more tedious. If you do want to do that, these link might help:

This is what I used to get this to compile and run [WayBack] Web Service Toolkit – Free Pascal wiki:

Build steps

FPC installation

  1. Run the 32-bit installer
  2. Keep all options except on the second install screen, disable Associate .inc files with FreePascal IDE
  3. Add C:\FPC\3.0.4\bin\i386-win32 to the user path

Building

  1. Recursively unzip wst-0.7u.zip
  2. Open a command prompt in the wst-0.7u directory
  3. Verify there is a ws_helper subdirectory

When compiling in Delphi, then you definitely need the FreePascal RTL sources for the PasTree unit; see [WayBack] fcl-passrc – Free Pascal wiki.

Converting a virtual IDE disk to a virtual SCSI disk (1016192)

Posted by jpluimers on 2020/09/11

Just in case I have a VM with only IDE disks of which one ore more need to become SCSI disks: [WayBack] Converting a virtual IDE disk to a virtual SCSI disk (1016192)

TL;DR

  1. Add one SCSI disk
  2. Install drivers for it and get it recognised
  3. When the VM is shutdown:
    1. Modify the disk description of the IDE disk to SCSI (hack) or
    2. (often easier) remove the disk, then attach it to the SCSI controller
