Re: [PATCH 1/4] EdkRepo: Installer should remove obsolete dependencies

Naïve question: why isn’t this upgrade handled when pip installs the new wheel? Are the dependencies not matched up correctly? I would think that pip would uninstall the old version on its own.

Subject: [EXTERNAL] RE: [PATCH 1/4] EdkRepo: Installer should remove obsolete dependencies

For the following section why are we singling out gitdb2 and smmap2 when deleting obsolete dependencies? Is there an alternative to hardcoding these values?

+                if (DeleteObsoletePackages)
+                {
+                    //
+                    // Delete obsolete dependencies
+                    //
+                    foreach (string PackageName in new string[] { "smmap2", "gitdb2" })
+                    {
+                        if (InstalledPackages.Where(p => p.Name == PackageName).FirstOrDefault() != null)
+                        {
+                            InstallLogger.Log(string.Format("Uninstalling {0}", PackageName));
+                            PythonOperations.UninstallPythonPackage(PythonPath, PackageName);
+                        }
+                    }
+                }

Thanks,
Ashley
