New Revision: 75010
URL: http://svn.reactos.org/svn/reactos?rev=75010&view=rev
Log:
[USETUP]: Implement work-in-progress code that, when upgrading an existing ReactOS
installation, verifies whether the (existing) system registry hives are valid (by loading
& unloading them, this allows using the built-in repair functionality if needed), or
not.
If a given hive cannot be repaired successfully, it is backed up (with a '.brk'
extension, "brk" as "broken"), then is marked up for recreation.
When all hives have been checked, if there are any hive that needs to be recreated, we
recreate its hive file, mount it, but we do *NOT* mount the other valid existing hives for
update. We create instead dummy registry hives so that we can actually use, as the update
code, the same one as the one used when fully creating the registry hives for a clean
installation (of course, this choice can be improved later on).
The update code (i.e. the same as the registry clean-install one) then adds the registry
keys & values, either putting them in the dummy registry hives (the ones that we
don't want to recreate) or in the registry hive that is recreated.
At the end, the (re)created registry hives are flushed back to disk, and a copy of them
(under a '.sav' extension) are created, so that they can be used for restoration
purposes if 2nd-stage (and up) goes berserk.
Extra fixes:
- Use the correct structure member field when initializing the 'InstallDir'
variable, when performing an upgrade.
- CreateNestedKey() should be better analysed to see whether it correctly creates the full
registry path compatible with volatile/non-volatile keys (under inspection).
