Description

Admittedly, I am a bit late at this.

See:

To do:

  • Verify and fix as needed that auxiliary pages are behaving properly when the uBO background page is terminated
  • Evaluate how port closing affects content scripts -- this might be the most problematic aspect of being non-persistent
    • This means the generic cosmetic filtering surveyor may be interrupted even though there still could be matching generic cosmetic filters to come
  • Optimize timing to generate a selfie, which will be even more key to quickly load back uBO's process into memory
  • Evaluate using storage.session to further speed up load sequence

]firefox] Improve load time & behavior from suspended state
eb66820 
Related issue:
uBlockOrigin/uBlock-issues#2969

Changes:

Use browser.alarms to trigger selfie creation. Presence of a selfie
improve markedly time to readiness when uBO is unsuspended.

Mirror content of storage.local to (in-memory) storage.session for
faster load to readiness when uBO is ususpended.

Make indexedDB to default fast cache by default
d4efaf0 
Turns out it's currently the fastest among the three currently
implemented (Cache, browser.storage.session, indexedDB). Possibly
because indexedDB can natively persist structure-cloneable data,
something uBO can now benefit with the work on abstracting away
the limitations of various storages being limited to persist only
text or JSON data.

Imrpove saving request stats for non-persistent background page

Related issue:
uBlockOrigin/uBlock-issues#2969

Related previous commit:
5a338b7210

The save-to-storage period is back to being around ~4 minutes, but
now browser.storage.session API is used to keep track of request
stats should the extension be suspended before the period elapse.
