Cache not invalidates

Descriptiion

on my setup the cache not invalidates correct.

symptom i faced

this results in some “errors” because of stale cache:

• #3324 Bug at "Shows PRs that touch the current file."?
• #3301 Feature Request: on an 404 with master try to redirect to main
• show-associated-branch-prs-on-fork shows old data after 2 days

Suggested: page refresh

source https://github.com/sindresorhus/refined-github/issues/3302#issuecomment-662129283

 maxAge: 1 / 2, 
 staleWhileRevalidate: 4, 

staleWhileRevalidate means that you’ll see cached data for 4 days after it expires (half a day), but one more page refresh will show the latest information.

i have done the page reload (<kbd>⌘</kbd>+<kbd>r</kbd>) and hard reload (<kbd>⌘</kbd>+<kbd>⇧</kbd>+<kbd>r</kbd>) many times before i reported an issue here.

How can i help

• is there a way to track this problem?
• how can i help to find the cause of the cache problem?

1. Run await browser.storage.local.get() in the extension console context
2. Yes. The first load after the expiration date will show the cached data, but also trigger the API request which updates the cache. The second load will use this new cache.

Please stop opening more issues about the cache.

I just verified that it works exactly as expected:

• I had bugs-tab with this cached data: { data: 20, maxAge: 1595771254270 }
• That maxAge is in 4 days and 13 minutes (bugs-tab is set to expire in 30 minutes + 4 days)

1. I waited those 13 minutes
2. I refreshed this page
3. The tab still reported 20 because of the staleWhileRevalidate behavior
4. I refreshed this page
5. The tab reported 21 and the cached object was { data: 21, maxAge: 1595773212201 }, which is 4 days and 28 minutes
