One of the issues that I see time after time is problems due to users having not followed the Migration instructions. I think it'd be beneficial if MacPorts included code to detect a major OS change and could then aid the user in completing the migration.
Migration consists of: Reinstall Xcode (and all associated command line utilities, accept license, etc.) Reinstall MacPorts (Is this necessary? Or only if you've performed a clean install? I thought 'selfupdate' was enough?) Make note of installed ports. Uninstall all ports. Clean all. Install all previously installed ports. So, the notation of installed ports, uninstall, clean, reinstall process sounds easily scriptable. This could even include an option to only reinstall the "requested" ports to save a bit of time, though unless the user's system was very old and didn't have the requested status populated this isn't likely to be different than installing everything. Of most benefit would be automatically restoring the requested status. Reinstalling Xcode can't be automated, but the required steps could be displayed for the user to follow. I know there has been discussion about determining which version is installed and how the latest Xcode versions make that a bit harder, but detecting the different steps would be beneficial (Xcode, command line tools, license). The same goes for reinstalling MacPorts (if that's actually necessary instead of 'selfupdate'). MacPorts could print the required steps and URLs and write out a status file so the next invocation after reinstall MacPorts (or even the installer) could pick up reinstalling the ports. Of course, detecting a major OS change should be easily detectable and would start off this whole process; either by prompting the user that MacPorts cannot continue without running 'port migrate-OS' or maybe even just running the migration if Xcode is already satisfied (and if 'selfupdate' is enough for the MacPorts upgrade). Thoughts? What's already available for this? What is needed? What isn't possible? -- arno s hautala /-| [email protected] pgp b2c9d448 _______________________________________________ macports-dev mailing list [email protected] http://lists.macosforge.org/mailman/listinfo/macports-dev
