926832 - HTTP cache v2: Time range to clear the cache is not respected

Status: NEW

(Core :: Networking: Cache, defect, P3)

Description

[Mihaela Velimiroviciu (:mihaelav)]

Attachment: about:univtest addon

The new cache back end doesn't respect the selected time range to clean the cache.

Prerequisites:
1. Turn the browser.cache.use_new_backend preference to 1 (and restart the browser)
2. Install the about:univtest addon

Steps to reproduce:
1. Navigate to some pages to gather cached data (e.g webmail, news sites, social networks)
2. Wait for a while (more than 1 hour)
3. Navigate to new sites, different from the ones from step 1
4. Go to Options/Preferences > Privacy and click on the "clear your recent history" link
5. Select the time range to clear (Last Hour) and make sure "Cache" is selected in the details list
6. Click the "Clear Now" button
7. Check the cache (about:univtest)

Expected result: Cached data from step 3 is removed. Cached data from step 1 is unaffected

Actual result: All cache is cleared

Even the old one doesn't ;)  This is not a regression, so not blocking anything.  We delete the whole cache for all time ranges.

This is mostly dep on the index.
