The redirectable resource has been renamed
`click2load.html`, so as to avoid uses of dash
characters and to also allow for future different
click-to-load resources.
Additionally, as a requirement to support click-to-load
feature, redirected resources will from now on no
longer be collapsed.

This new feature should considered in its draft
stage and it needs to be fine-tuned as per
feedback.
Important: Only embedded frames can be converted
into click-to-load widgets, as only these can be
properly shieded from access by page content.

Name: `uiTheme`
Default: `unset`
Values:
- `unset`: uBO will pick the theme according to
browser's `prefers-color-scheme`
- `light`: force light scheme
- `dark`: force dark theme
This advanced setting is not to be documented yet as
it has not been decided this is a long term solution.
- Added values for dark mode
- Using the photon colors and reviewing material design - Put this together.
- Correct fieldset-header-ink
- Removed color variables already listed.
- Removal of !important and revert to some already approved colours.

Double-cliking on a URL will cause the whole URL to be
selected, thus making it easier to navigate to this
URL (through your browser "Open in new tab" entry in
contextual menu).
Unrecognized scriptlet names will be highlighted so as
to warn that the filter is not going to be effective.
Injecting declarative CSS `:style()` selector could cause
the instatiation of the procedural filterer, even when
there was no actual procedural cosmetic filter to
enforce.
This commit ensure that the procedural cosmetic filterer
is instantiated only when there are actual procedural
filters to enforce.

Changes:
From now on, uBO will allow click-to-subscribe on only
a few select domains, currently:
- https://filterlists.com/
- https://github.com/
- https://github.io/
More domains can be added if and only the demonstration
is made that more than a marginal number of filter lists
can be subscribed from those domains.
The browser alert box is no longer used to confirm
subscription to a filter list. Instead, the asset
viewer has been expanded to serve that purpose. This
way, users can peruse at the content of a filter list
before subscribing to it.
Now that the element picker user interface is isolated
frompage content world, there is no need to use the
`important` modifier for the element picker's own
CSS styles.
Further iterating on the work done in following commit:
- 1268f0ae43
This commit adds a new widget to the element picker to
control the depth of a cosmetic filter selector. The
new widget is essentially just another way of selecting
the depth, which is still controllable through picking
one of the cosmetic filters in the list of candidates.
In addition to what is deemed really bad lists by consensus,
some lists will also be labelled "really bad list"
temporarily so as to force-remove them from the set of
filter lists.
This will be the case for filter lists which are not
necessarily "bad lists" but which were once part of
uBO's stock filter lists and have been removed since
then for various reasons.
This will ensure that the majority of users who do not
modifies uBO's default listset will still have a
configuration which matches the official default listset.

The ctrl key is no longer used to adjust specificity of
a candidate filter.
A new widget has been added to adjust the specificity of
a candidate filter to various level. The widget will be
visible as long as the candidate filter matches one entry
in the list of suggested candidate cosmetic filters.

In the previous commit, the element picker dialog was
isolated from the page content. This commit is to also
isolate the svg layers from the page content.
With this commit, there is no longer a need for an anonymous
iframe and the isolated world iframe is now directly
embedded in the page.
As a result, pages are now unable to interfere with any
of the element picker user interface. Pages can now only
see an iframe, but are unable to see the content of that
iframe. The styles applied to the iframe are from a user
stylesheet, so as to ensure pages can't override the
iframe's style properties set by uBO.
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.

For yet unknown reasons, in Chromium 84 the rendering of
`svg/use`-based icons in the dashboard causes page load
stall and undue high memory usage when the dashboard is
opened, especially the Filter list pane.
The fix in this commit is to avoid using `svg/use` and to
directly create and insert the `path` element defining an
icon.
Added a dotted box around found text occurrences,
as just pale yellow to highlight the text is not
enough to visually distinguish from surrounding text.
Iterating through found text occurrences will now
ensure they are vertically positioned in the middle
of the editor.
Code review following latest changes.
Also, move the input field to the left so that it
renders properly on smaller displays and does not
jump around when the result position/count numbers
change.
This also makes it easier to add more functionality
to the editor's toolbar in the future.

Since the search worker can go away after its time-to-live
elapsed, we may need to pass again the haystack on which
search operations are performed.
Before this commit, CodeMirror's add-on for search occurrences
was limited to find at most 1000 first occurrences, because of
performance considerations.
This commit removes this low limit by having the search
occurrences done in a dedicated worker. The limit is now
time-based, and highly unlikely to ever be hit under normal
condition.
With this change, all search occurrences are gathered,
and as a result:
- All occurrences are reported in the scrollbar instead of
just the 1,000 first
- The total count of all occurrences is now reported, instead
of capping at "1000+".
- The current occurrence rank at the cursor or selection
position is now reported -- this was not possible to report
this before.
The number of occurrences is line-based, it's not useful to
report finer-grained occurences in uBO.
Since it's possible to execute specific code paths according
to whether the context is that of a worker or not, it's possible
to keep the main/thread code in a single file. Keeping the
main/worker code paths into a single file is more convenient
for both code maintenance and code review.

Usage of space in network filter patterns will now be
strictly interpreted as the filter being a hosts file
entry.
Usage of space in any other scenario will cause the
pattern of the network filter to be rejected as
erroneous.
The pseudo user styles code served only browsers based
on Chromium 65 and earlier -- Chromium 66 supports
native user styles and was first released more than two
years ago.
In Chromium-based browsers, the pseudo user styles code
is being unconditionally injected in every page/frame
just in case the browser is version 65 or earlier.
Removing pseudo user styles reduce uBO's main content
script in Chromium-based browsers by more than 20K.

Lines in AdGuard filter lists have trailing `\r`
characters, and these caused the redirect engine
compile code to reject as invalid the redirect

This is trivially fixed by trimming the raw option
strings before parsing it in the redirect engine.

CodeMirror's code folding reference:
- https://codemirror.net/doc/manual.html#addon_foldcode
This commit adds support for code-folding to the filter
list editor/viewer.
The following blocks of code are foldable by clicking the
corresponding marker in the gutter:
- !#if/#endif blocks
- !#include blocks
Addtionally, the following changes:
- The `!#include` line is now preserved when importing a
sublist
- The `!#if` directives will be syntax-colored according
to whether they evaluate to true or false on the current
platform
- Double-clicking on a foldable line in the gutter will
select the content of the foldable block
- Minor visual improvement to matching brackets
Auto-completion will work only for uBO's own
tokens, compatibility-related tokens[1] will not be
taken into account for auto-completion.
The reason is to not have the compatibility-related
tokens get in the way of auto-completion in order
to not inconvenience uBO's filter list maintainers.

Invalid values for `!#if ...` will be highlighted as errors.
Auto completion is now supported for both the directives
themselves and the valid values for `!#if ...`.
For examples, when pressing ctrl-space:
- `!#e` will auto-complete to `!#endif`
- `!#i` will offer to choose between `!#if ` or `!#include `
- `!#if fir` will auto-complete to `!#if env_firefox`
Additionally, support for some of AdGuard preparsing
directives, i.e. `!#if adguard` is now a valid and will be
honoured -- it always evaluate to `false` in uBO.
In case of invalid `Expires` value -- i.e. `NaN` -- do
not use `1` as default value, just let uBO pick the
value according to the global default (which is `5` as
of commit time).

Unicode characters inside hostname part of a filter will
be converted to punycode.
Unicode characters anywhere else in the pattern will be
percent-encoded.
Unicode characters which cannot be encoded will cause a
filter to be invalid.
This fix the case of the following filter:
trk*.vidible.tv
Not matching:
https://trk.vidible.tv/trk/.vidible.tv
The wildcard is supposed to match any number of
characters, including zero characters. The issue
is that the code was not matching zero characters.
This is due to an incorrect comparison in
BidiTrieContainer.indexOf(), causing the code to
bail out before testing for the zero character
condition.
The regression broke filters of the form:
||trk*.vidible.tv^
The new parser will eventually interpret differently
wildcard characters when they are used in a manner
meant to represent only hostname-valid characters,
but this will come in a future version -- for now
the default meaning must be preserved until the
static network filtering engine is modified to
enforce the new interpretation.

For unknown reasons at this point, it appears some users
end up with a truncated version of EasyList, leading to
improper blocking in uBO.
This commit adds a heuristic to discard a downloaded list
when its new size is more than 25% smaller than the
currently cached version.
This commit adds CodeMirror's auto-completion capability
to the _My filters_ pane.
Currently, auto-completion is available for scriptlet
tokens: pressing ctrl-space while the text cursor is
positioned where a scriptlet token should appear will
cause auto-completion to kick-in. In case of ambiguity,
CodeMirror's widget to pick a specific scriptlet will
appear.
Rename `l` property to `len`, to avoid ambiguity as
`l` could mean _left_ or _length_. Typically `l` is
to be used for _left_ (whereas `r` is to be used for
_right_).
Additionally, add CodeMirror's bracket-matching and
bracket auto-closing to _My filters_ pane and and
bracket-matching to asset viewer page.
Specifically, do not invalidate valid hostnames when
there are extraneous separators: that sort of error
will be visually highlighted but will not otherwise
prevent a filter from being properly enforced.
This ensures proper garbage collection once the parser
is no longer referenced -- this is important now that
the parser is instantiated on-demand only.

This commit moves some of the parsing logic of static
extended filtering into the static filtering parser; this
allows better syntax highlighting and creation-time
error-catching for cosmetic, HTML, and scriptlet filters.
Specifically:
There can't be more than one `redirect` or `csp`
option.
There can be no type specified when there is a
`csp` option.
There must be one single network-related type when
there is a `redirect` option. Since `empty` and
`mp4` imply a `redirect` and a network-related
type, these can't be used along another `redirect`
or network-related type.

The regression was made apparent be the fact that
AdGuard filter lists have lines ending with the
CR character.
Computing storage-used figures can take longer than
usual sometimes when a lot of filter lists are enabled,
and this can cause the Settings pane to take longer to
be filled the first time it is opened. Fetching
settings and storage-used figures separately removes
that potential delay (they were fetched together in
a single Promise.all() call).

The new parser needs to be able to deal with trailing
newline characters, which if present will be interpreted
as trailing spaces.
A new standalone static filtering parser is introduced,
vAPI.StaticFilteringParser. It's purpose is to parse
line of text into representation suitable for
compiling filters. It can additionally serves for
syntax highlighting purpose.

This commit adds support entity-matching in the filter
option `domain=`. Example:
pattern$domain=google.*
The `*` above is meant to match any suffix from the Public
Suffix List. The semantic is exactly the same as the
already existing entity-matching support in static
extended filtering:
- https://github.com/gorhill/uBlock/wiki/Static-filter-syntax#entity
Additionally, in this commit:
Fix cases where "just-origin" filters of the form `|http*://`
were erroneously normalized to `|http://`. The proper
normalization of `|http*://` is `*`.
Add support to store hostname strings into the character
buffer of a hntrie container. As of commit time, there are
5,544 instances of FilterOriginHit, and 732 instances of
FilterOriginMiss, which filters require storing/matching a
single hostname string. Those strings are now stored in the
character buffer of the already existing origin-related
hntrie container. (The same approach is used for plain
patterns which are not part of a bidi-trie.)
Pressing spacebar will toggle god mode in popup
panel.
This capability shouldn't encourage people to
misuse _allow_ rules as having to press the
space bar act as an extra necessary step which
purpose is to make the creation of _allow_ rules
more mindful.
There have been too many examples out there of users
opting-in to "I am an advanced user" and yet still misusing
dynamic filtering by creating _allow_ rules where _noop_
rules should be used.
Creating _allow_ rules has serious consequences as these
override blocking static filters and can potentially
disable other advanced filtering ability such as
HTML filtering and scriptlet injection -- often used
to deal with anti-blocker mechanisms.
The ability to point-and-click to create _allow_ rules
from the popup panel is no longer allowed by default.
An new advanced setting has been added to enable
the ability to create _allow_ rules from the popup
panel, `popupPanelGodMode`, which default to `false`.
Set to `true` to restore ability to set _allow_ rules
from popup panel.
Since the creation of _allow_ rules is especially useful
to filter list authors, to diagnose and narrow down site
breakage as a result of problematic blocking filter,
the creation of _allow_ rules will still be available
when the advanced setting `filterAuthorMode` is `true`.
This change is probably going to be problematic to all
those users who were misusing dynamic filtering by
creating _allow_ rules instead of _noop_ rules -- but
the breakage is going to bring their misusing to their
attention, a positive outcome.
Default to `unset`.
To allow users to bypass uBO's default CSS styles in
case they are causing issues to specific users. It is
the responsibility of the user to ensure the value of
`uiStyles` contains valid CSS property declarations.
uBO will assign the value to `document.body.style.cssText`.
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/1044
For example, in the case of the issue above, one could
set `uiStyles` to `font-family: sans-serif` to force uBO
to the system font for its user interface.
I can't remember the reason for the added thin gap,
there is no benefit from this for the desktop panel,
probably stray CSS code from some earlier fiddlings.
The "blocked since install" row has been moved
