Feed Updates and Article Life Cycle

As a rule every feed is updated automatically in background according to feed update schedule. Besides manual feed update can be performed at any time by selecting the corresponding menu item. RSS feeds contain only article time, name, description and link to the full article content. For each article the application downloads the full article content (single HTML file) and indexes it using FTS (full text search) database.

Usually when the feed is updated some new articles (date, title and description) are downloaded.

The following table lists typical steps of the article life cycle (FTS abbreviation below stands for 'Full Text Search'). Some steps depend on settings - see 'Preferences'.

# Step Description
1 RSS Article data (date, title and description) is extracted from RSS file.
2 Cache Article is downloaded and is saved in cache for FTS processing. If 'Prefetch article for offline reading' flag is switched on then the full article content is downloaded for offline reading as well.
3 Database Article is saved in the FTS database and is waiting for keywords analysis. Now it is available for search.
4 Analysis Article is analyzed and placed to the appropriate topic (together with its feed).
5 Retention Article is available for the user in 'Articles List' view, 'Article Description' view and 'Article Offline' view (If 'Prefetch article for offline reading' flag was switched on in the time of download). During this time the user can redownload the article using selected download parameters.
6 Cleanup The application saves article itself and all article files (if any) for a limited period of time measured in days from the time of the first download (aka 'days to keep'). After the retention period is over all article files (that are not used by other articles) are deleted.

All actions listed above are performed in the background threads with low priority to prevent freezing the user interface responsiveness. For large HTML files some actions can take anywhere from 10 to 100 seconds and more and depends on the total load. Typically the article reaches some step 3 (available for search) and step 5 (article is placed to the corresponding topics) of its life cycle after a while. Just wait, please.
