[Pan-devel] newsrc with DB

[K. Haley]

I just realized what Charles ment about supporting newsrc files with the 
DB back-end.  Since newsrc files track UIDs for physical servers, 
loading new headers becomes a bit more complicated.  Things would have 
to go something like this:

at startup:
load list of servers from DB
foreach server
 foreach group in newsrc file
   if group not in Group
     add to Group
   get Group:id
   update subscibe status in main group list
   get G_S:id
   foreach UID
     if G_S:id and UID in G_S_A
       if Article:id !=NULL    update Article read status
     else
     add to G_S_A with Article:id = NULL

to load new headers:
remove NEW status from exising articles in this group
foreach new header on server
 if msg-id not in Article
   add to Article
 get Article:id
 if G_S:id and UID in G_S_A
   if Article:id == NULL in G_S_A
     update Article:id in G_S_A
     mark Article read
 else add to G_S_A

Hopefully that pseudo-code is not to difficult to understand.  I also 
realize that there are ways to speed it up but that doesn't matter at 
this point.
