Hi,

In continuing to misjudge what would be an easy bug to fix I had an attempt at FS#8645 - Restore pacsaves on install [1]. The attached patch is a definite work in progress.

I have two queries: 1) Would it be better to notify the user of the restore or to query them. Either way they will get a notification about the new file being installed to .pacsave. I'm leaning on query here because that would allow the user to stop really old files being restored.

2) Should I worry about the case where a file used to be backed up but is not now. This seems an edge case but would result in the file being restored then overwritten (I think.... I need to look at that further).

Hrm, what happens if, I install foo-1.0, uninstall it, then later reinstall foo-2.0 which has a totally different config format. We wouldn't be storing the OLD md5sum for the config file if a package is uninstalled.

Perhaps we should actually ask the user, due to that case.

Yes, thats what I was getting at in 1). For 2) I meant files that used to be in the backup array and no longer are were getting overwritten. Anyway, I have reworked this so that the user gets queried to restore a pacsave file and the file to be extracted now always gets saved as .pacnew. I will probably finish tiding this up at the weekend once I have tested it some more. Allan
