[Feedreader-development] Memory issue

[Karsten H. <mai...@kh...>]

Some days ago i got the following error:

Started FR, updated feeds, read all new headlines.
Minimized FR.
Later FR did the autoupdate and a message appeared 'Out of memory'.

At that point i had set 'Archive all headlines' and the total size of 
the xml files were ~ 9mb. Headlines was the biggest, ~ 8.5mb.

The machine i was using has 256mb RAM running Win2000.

Since i set 'Archive only latest 50 headlines' and restarted FR the
error disappeared.

The problem is that we use xml to store the headlines.
When using DOM for xml handling, the whole xml document gets loaded into 
  memory. Obviously the amount of memory needed to handle xml files is
not just the file size, but it is the filesize * x.

Suggestion:
Change the way the headlines are stored. Don't use xml.
For each feed create a ascii file and store just the headlines of this
feed in the file. Filename could be the guid of the feed.
Internally all headlines are stored in an array, so switching to
separate ascii files will need just a rewrite of the in-/output routines
for the headlines.
