Aims to improve compatibility for the lit framework (e.g. what Reddit is using).
1 - Adds support for adoptedStyleSheets to the Document and ShadowRoot
2 - Adds mock support for replace and replaceSync to the CSSStyleSheet
3 - Optionally include shadowroot in dump
4 - Special-case setting innerHTML on a TemplateElement
Currently, fetch --dump includes <script> tag (either inline or with src). I
don't know what use-case this is the desired behavior. Excluding them, via the
new --noscript option has benefit that if you --dump --noscript and open the
resulting page in the browser, you don't re-execute JavaScript, which is
likely to break the page.
For example, opening a --dump of github makes it look like the page is broken
because it re-executes JavaScript that isn't meant to be re-executed.
Similarly, opening a --dump in a browser might execute JavaScript that
lightpanda browser failed to execute, making it looks like it worked better
than it did.
The wait_for_network_idle demo often times out for me. I don't see any reason
to have the default so low. More likely to cause user scripts to unnecessarily
fail.
1 - Make log_level a runtime option (not a build-time)
2 - Make log_format a runtime option
3 - In Debug mode, allow for log scope filtering
Improve the general usability of scopes. Previously, the scope was more or less
based on the file that the log was in. Now they are more logically grouped.
Consider the case where you want to silence HTTP request information, previously
you'd have to filter out the `page`, `xhr` and `http_client` scopes, but that
would also elimiate other page, xhr and http_client logs. Now, you can just
filter out the `http` scope.
Outputs in logfmt in release and a "pretty" print in debug mode. The format
along with the log level will become arguments to the binary at some point in
the future.
1 - Add a log_level build option to control the default log level from
the build (e.g. -Dlog_level=debug). Defaults to info
2 - Add a new boolean log_unknown_properties build option to enable
logging unknown properties. Defautls to false.
3 - Remove the log debug for script eval - this can be a huge value
(i.e. hundreds of KB), which makes the debug log unusable IMO.
Replaces the existing, very specialized Notification with something more
general.
Currently, the existing page_navigate and page_navigated have been migrated.
Telemetry's page navigation event now also hooks into these events to generate
the telemetry record.
- Pages within the same session have proper isolation
- they have their own window
- they have their own SessionState
- they have their own v8.Context
- Move inspector to CDP browser context
- Browser now knows nothing about the inspector
- Use notification to emit a context-created message
- This is still a bit hacky, but again, it decouples browser from CDP
In order to support click handling on anchors from JavaScript, we need some hook
from the page/session to the CDP instance. This first phase adds notifications
in page.navigate, as well as a primitive notification hook to the session.
CDP's existing Page.navigate uses this new notifiation system.
When set, this disables the host verification of all HTTP requests. Available
for both the fetch and serve mode.
Also introduced an App.Config, for future command line options which need to
be passed more deeply into the code.
The two bigger changes here are:
1- The http_client has been moved from the Session to the Browser, allowing
its connection pool to be re-used across multiple sessions
2- The browser now has a page_arena which is used for all page-level allocation
and which can be re-used between pages (currently retains 1MB of memory).
Previously, pages uses an arena that was tied to the lifetime of the page,
thus it could not be re-used.
Using the Bench allocator for zig-js-runtime, allocated bytes went from
1347037879 to 834932438 (in a RUNS=1000 of puppeteer demo).
Various other changes to try to simplify the API and remove the possibility
of invalid states. For example, session.newPage() now includes the logic for
page.start() so that there should now never be a page that wasn't started.
