Meant to be merged alongside https://github.com/lightpanda-io/browser/pull/3680
but split up to make it easier to review.
317 of the 554 warn/err are now debug. Many of these are events that might be
interesting to a lightpanda browser developer, but not so much an end-user (
end-users might still care about some of these, but more likely in the aggregate
via metrics).
The ultimate goal is to make --log-level warn a useful default.
(this also tweaks how the page meta data is displayed in the pretty logs)
Saw a site return "Content-Type: charset=UTF-8;charset=UTF-8" on scrape. Not a
valid header and it correctly fails to parse. Except...CDP fails to RI on these
since it tries to parse and bubbles. Safe to swallow this error here and
continue with the response serialization.
Ultimate goal is to improve the logging to be more useful by:
1 - identifying the page being navigating
2 - downgrading most page-loading errors to debug
3 - provide page statistics (in logs, via cdp).
So, the logs would look something like:
```
info page-navigate page=3392 url=https://.....
debug urlblocked page=3392
debug timeout page=3392 url=script.js
info page-done page=3392 url=https://....
```
The log level for page-done will be the @max() of any log level for that page
so that if you run --log-level warn, and you get:
```
info page-navigate page=3392 url=https://... <-- filtered out
debug timeout page=3392 url=script.js <--filtered out
warn unknown module lookup page=3392 identifier=blah.js
warn page-done page=3392 url=https://....
```
So that any page event can be linked to the top leveL URL, while still
respecting the --log-level.
This first parts adds the log-level page context, and the thread local
variable.
Resolving the cascade for every element on each mutation made an
append + scrollHeight read up to 12x slower. Virtualizers set their
spacer height inline.
If the server gives a status reason, report it as-is. Only default to the
zig code->reason map when one isn't given.
Also, don't force a 407 status code when auth_challenge is present.
https://github.com/lightpanda-io/browser/pull/3619 added proper support for
Sanitizer. A consequence of that is that every setHTML/parseHTML without an
explicit creates the default Sanitizer (with its ~300 entries).
This commit creates 1 app-level default sanitizer and uses it, internally, when
none is explicitly given. The sanitizer is immutable so can safely be used
across threads.
Adjacent placeholder anchors, like a JS-driven nav, ran together as
HomeAbout. Keep the standalone line placement linked anchors get and
drop only the link syntax.
`lightpanda version.io` was rejected as a misspelt `version`, 3 edits
within the length-scaled limit. Like curl, it fetches now: the command check
shares --dump's isUrlLike.
