This commit fixes deleting all entries when cloud
storage usage is beyond allowed limit.
The issue would prevent pushing new data well within
quota limit because the old data beyond limit was
never removed in the first place.
This commit adds concept of "really bad list" to the
badlists infrastructure. Really bad lists won't be
fetched from a remote server, while plain bad list
will be fetched but won't be compiled.
A really bad list is denoted by the `nofetch` token
following the URL.
Really bad lists can cause more serious issues such
as causing undue launch delays because the remote
server where a really bad list is hosted fails to
respond properly and times out.
Such an example of really bad list is hpHosts which
original server no longer exist.
Many filter lists are known to cause serious filtering
issues in uBO and are not meant to be used in uBO.
Unfortunately, unwitting users keep importing these
filter lists and as a result this ends up causing
filtering issues for which the resolution is always
to remove the incompatible filter list.
Example of inconpatible filter lists:
- Reek's Anti-Adblock Killer
- AdBlock Warning Removal List
- ABP anti-circumvention filter list
uBO will use the following resource to know
which filter lists are incompatible:
- https://github.com/uBlockOrigin/uAssets/blob/master/filters/badlists.txt
Incompatible filter lists can still be imported into
uBO, useful for asset-viewing purpose, but their content
will be discarded at compile time.
When a 3rd argument was provided, the scriplet would
log information related to window popup operations,
regardless of the value of the argument.
The 3rd argument is now parsed in a formal manner. It
is meant to be one or more space-separated tokens which
are used to fine tune the behavior of the scriptlet.
Tokens:
log:
Cause the scriptlet to log information regarding
how window.open() is used by the page on which the
scriptlet is used. Useful only to filter creators.
obj:
Use an `object` element instead of `iframe` element
(default) as a decoy to be used in place of a popup
window, when the page requires a valid `window`
instance to be returned.
Cloud storage is a limited resource, and thus it
makes sense to support data compression before
sending the data to cloud storage.
A new hidden setting allows to toggle on
cloud storage compression:
name: cloudStorageCompression
default: false
By default, this hidden setting is `false`, and a
user must set it to `true` to enable compression
of cloud storage items.
This hidden setting will eventually be toggled
to `true` by default, when there is good confidence
a majority of users are using a version of uBO
which can properly handle compressed cloud storage
items.
A cursory assessment shows that compressed items
are roughly 40-50% smaller in size.
