Barret, you should be able to continue on top of the patch I posted in bug 1520879.

I didn't port the parent process side of things to C++ (see the nsIBrowser methods added in that patch) because it wasn't clear to me if that's easy to do in an incremental fashion. Specifically, RemoteWebProgressManager would need to be ported to C++ in order to be able to do something useful but doing so before the other JS consumers were ported would have required creating an XPIDL interface for the new C++ class in order to allow calling it from both C++ and JS and that seemed like a lot of work. Plus it wasn't obvious if it would even be worth doing since the progress listeners themselves are implemented in JS so we'd ultimately be calling from C++ to JS in the parent process anyway, unlike the content process side where my patch makes us avoid a C++ to JS call for onContentBlockingEvent notifications completely.

Agree, at this point there doesn't seem to be any particular need to convert the parent side to C++, unless someone had profiles that show it causes janky. Even then, I think it would be a much lower priority than the child side.

One last thing other thing to note that on the parent side, even calling AsBrowser() will run JS, so avoiding running JS will boil down to not touching mFrameElement at all...

pauljt, could you recommend some reviewers from the security (psm) team for this work? Part of this touches on re-implementing the serialization of nsNSIX509Cert, nsIX509CertList, and nsITransportSecurityInfo for IPDL instead of using the nsISerializable implementation.

I'd defer to Dana for reviews in that space.

Feel free to flag me for feedback though, I'd be keen to review this myself as well (but my review won't help you land it :)

I can review PSM changes. Heads up that making those kinds of changes are likely going to require necko changes as well, since the serialization of those components are used in a few different areas. Also note that we generally need to be able to deserialize older formats because these structures are saved in the cache and persist across updates.

Thanks Dana! The existing nsISerializable implementation isn't changing -- I'm implementing IPDLParamTraits for nsITransportSercurityInfo. With that said, I don't think this work needs to support deserializing older formats since this is just for IPC and the reading from the cache should use the existing nsISerializable implementation, but let me know if I'm incorrect about that.

Ah - I imagine there won't be any issues with that, then.

Hi :kmag,

I'm working on this bug and ran into the issues outlined in bug 1471327. Per your comment:

So, there are essentially two different kinds of about:blank loads: 1) Initial about:blank contentViewer creations that are going to be replaced with a real document. These have document.readyState == "uninitialized", and should generally be ignored. And, 2) real about:blank document loads, either directly loaded, or implicitly loaded for the sake of running things like javascript: URIs. These have document.readyState == "loading", "interactive", or "complete".

Telling them apart can be tricky, but we already have to do it for the sake of extension content scripts, so it's not really much trouble to do the same in other cases.

What else is tricky to distinguish them apart from checking the readyState attribute? Is there anything else I need to take into consideration?

Thanks!

Gijs, you may also know about this?

(In reply to Barret Rennie [:brennie] from comment #13)

Gijs, you may also know about this?

I'm not seeing a concrete question. Naively, I'd expect you're just having to convert whatever logic we have for about:blank stuff in WebProgressChild/RemoteWebProgress.jsm into C++.

Broadly, we have some code specifically handling initial about:blank in tabbrowser.js, but AFAICT (see bug 1471327 comment 18) the extant checks aren't actually very good. IIRC they only cope with STATE_STOP notifications whereas obviously other ones are also fired.

Are you running into specific test failures or something? Something specific you're wondering how to convert from the old to the new implementation?

Sorry, I meant the question I posed to :kmag. Is there anything besides document.readyState == "uninitialized" that I should be checking to see if I shouldn't be propagating events to the TabParent?

(In reply to Barret Rennie [:brennie] from comment #15)

Sorry, I meant the question I posed to :kmag. Is there anything besides document.readyState == "uninitialized" that I should be checking to see if I shouldn't be propagating events to the TabParent?

I think if you're in C++ land you can check Document->IsInitialDocument(). I don't know if that's sufficient for the STATE_START events; do you have a document at that point? If not, I expect :nika or :qdot would know how to distinguish these.

Going by the comments in the JSM, we won't have a document by then and accessing it will create a new about:blank document.

:nika, any thoughts on what can be done here?

I've thought about just adding a flag on something (docshell?) that gets set approximately here and not propagating the events until that flag is set.

(In reply to Barret Rennie [:brennie] from comment #17)

Going by the comments in the JSM, we won't have a document by then and accessing it will create a new about:blank document.

It will from JS, but you can ask a docshell GetExtantDoc() and that won't (will just return nullptr if no doc exists).

However, the first thing to load isn't necessarily an initial about:blank doc so we'd need to do additional checks in the case where no doc has yet loaded to determine what it is we're starting to load.

Ah I wasn't aware of that method.

Is Document::IsInitialDocument() sufficient? If not, what are the other checks that need to be done? This search on searchfox only shows a few usages of IsInitialDocument, none of which do anything further.

Redirecting the ni? to :qDot because he knows more about the document loading lifecycle.

Clearing needinfo since its been ~a month without response.

The implementation of WebProgressChild.jsm filters all nsIWebProgress events
through an nsBrowserFilter. We need to do this in the TabChild as well, but
TabChild currently only handles onContentBlockingEvent, for which
nsBrowserFilter only calls the underlying listener.

We also unregister the progress listener much earlier in TabChild::Destroy as
this method causes OnStateChange event to be triggered later on, which we are
not interested in capturing.

Changing RemoteWebProgress to a C++ XPCOM object will cause the request being
passed into the onStateChange handler in promiseBrowserLoaded to become a
wrapped XPCOM object for an nsIRequest, instead of the JS object it was
previously. This results in the attribute lookup for originalURI on the
request to fail, leading to cascading failures.

Depends on D24808

Due to adding a new CPP file in the next change, the unified build fails due to
files being shuffled around between translation units. This change fixes the
build.

Depends on D24809

Depends on D24810

WindowGlobalChild.cpp was relying on several headers already included by other
files in its unified build translation unit, but the addition of the
RemoteWebProgressRequest in the next change bumps them into another translation
unit and breaks the build.

The missing #include and using namespace statements have been added,
allowing builds to succeed.

Depends on D24937

The RemoteWebProgressManager is now implemented in terms of a
nsIWebProgressListener. This paves the way for reconstructing the
nsIWebProgress and nsIRequest passed to the event handlers in C++ instead of in
JS and will alllow for a cleaner overall design.

While here, I also cleaned up RemoteWebProgressManager to use the class
syntactic sugar.

Depends on D24940

Now that we have access to the RemoteWebProgress from the TabParent and can
construct RemoteWebProgress and RemoteWebProgressRequests in C++, we can
reconstruct the RemoteWebProgress and RemoteWebProgressRequest in the TabParent
instead of RemoteWebProgressManager. This improves the API for nsIBrowser and
RemoteWebProgressManager, removing the need for the
callWebProgressContentBlockingEventListeners method in both. It also means we
won't need to implement callWebProgress*Listeners for methods on nsIBrowser
and RemoteWebProgressManager for all other nsIWebProgress events.

Depends on D24941

The browser_talltabslistener.js test verifies that (a) certain
nsIWebProgress events occur in the correct order and (b) that the events come
from the correct browser. However, the part of the test that listend for
onStatusChange messages did not actually confirm that they were triggered or
that the correct number of them were triggered. The ordering of the
onStatusChange events with respect to the other nsIWebProgress events is
non-deterministic because onStatusChange events are filtered through the
nsBrowserStatusFilter, which may or may not put them on a delay timer (due to
the message being repeated often).

The presence of this timer makes for a lovely race condition. Now that the
TabChild's onStatusChange event handler is registered earlier (in
TabChild::Init instead of the WebProgressChild.jsm) we are getting more
onStatusChange messages and the race more frequently results in a failing
test. This is due to one of the test cases swapping browsers but not
explicitly waiting for all onStatusChange events to come in, so the test case
will run with swapped browsers and a onStatusChange event from a previous
test case will leak through, causing the test to fail.

The simplest way to fix these tests is to just remove the onStatusChange
listeners, since they do not assert whether or not they are received -- the
tests will pass even if no onStatusChange events are sent.

Depends on D25446

We do not need to handle onProgressChange64 notifications since the TabChild's
web progress events are filtered through an nsBrowserStatusFilter, which
truncates onProgresChange64 event values to 32-bit integers and then calls
onProgressChange.

Depends on D25648

I wasn't able to land this patch as it needs rebasing and lando can't do it automatically

Please rebase your patch and commit again afterwards.

Rebased. Should be good to go.

Unrelated to this bug, but it would be really nice if we could find a way to make these tests not depend on random bits of overhead of the tab load cycle and actually measure just the SVG performance they're supposed to be testing...

On the other hand, it is also good to see how somewhat random change elsewhere affects to this kinds of tests. It tells us that we were running JSMs at very wrong time. No JS should run in hot code paths.

But that test's repeated loading of things makes bits of the browser "hot" that aren't actually all that hot in normal use. If we consider anything related to navigation "hot" then I guess we should be implementing the URL bar (and back/fwd buttons, and anything else that depends on docshell state/history) in C++ next...

Sure, but having that overhead show up in random tests that are unrelated isn't helpful. The tsvg tests are supposed to be measuring SVG performance, but wind up mostly measuring a bunch of unrelated stuff instead, since the SVG code it runs is so much cheaper than the extraneous code.

Ideally, for those tests anyway, we should find a way to measure the actual SVG stuff we care about in-between the extraneous bits. If we want to actually measure the overhead of a super trivial page load, that should really be a separate test.

The nsBrowserStatusFilter fushes pending status and progress updates when an
OnStateChange event for a STATE_STOP state is triggered. This may run its
OnProgressChange and OnStatusChange listeners, which may in turn run arbitrary
JavaScript or even remove the web progress listener from the filter. When this
happens, we will continue to call the OnStateChange event handler on a listener
that is now a nullptr, causing a crash.

We now explicitly check that we still have a web progress listener before
continuing and have renamed the ProcessTimeout function to a more descriptive
name (CallDelayedProgressListeners) that indicates what it actually does.

Depends on D28123

We now also only access the document when the state is
nsIWebProgress::STATE_STOP. The comments in the previous code indicated that
touching the document inside the event handler when the state is not STATE_STOP
would result in the content creating a new about:blank document to retrieve the
values from. However, it then went on to do this in another location, causing a
document to be created whenever we received an onStateChange event. This should
no longer occur.

Before the WebProgress event handlers started migrating to C++, the parent
process would only receive WebProgress events after the child process had
finished loading the WebProgressChild script. Now that listeners are registered
much earlier (before the BrowserChild has finished setting up its frame
scripts), the BrowserParent would receive WebProgress events that were
heretofore not received unless the BrowserChild was very careful about when
it sent the IPC messages.

However, even while being very careful, the OnStateChange event handler would
always fire events for initial about:blank loads that break a lot of unit
tests. Before porting that event, we are now ensuring that the WebProgressChild
has finished loading so that we will receive only the WebProgressEvents that we
were previously expecting.

The latest patches up for review fix these crashes.

The BrowserParent's IPC receive methods for nsIWebProgress events in the
BrowserChild were all doing the same set up to ensure they had the correct
state to process them. This has now been refactored out into a single method.

When TabParent::ReconstructWebProgressRequest was introduced in
31b206e2046f63af31424489e3d61d7761805878, it mistakenly was unconditionally
constructing an nsIRequest from the received RequestData, even when the URI
was null.

Additionally ReconstructWebProgressRequest has been updated to use the Gecko
style for out parameters (accepting an nsIFoo** and passing
getter_AddRefs(...) instead of nsCOMPtr<nsIFoo>&).

Depends on D34445

Depends on D34563

Depends on D34564

The WebProgress#sendLoadCallResult method only existed to send a empty async
message and was only called from the WebNavigationChild. Since
WebNavigationChild is in the process of being removed, it makes sense to
inline the replaced method into its call site.

ipc_message_utils.h defines IPDLParamTraits on windows for some things like
HWND and HANDLE. However, it doesn't directly include windows.h on Windows to
include them. All other usages seem to rely on including base/process.h, which
does include windows.h and adds the appropriate typedefs.

Depends on D35089

This is the last message that WebProgressChild was sending to the
RemoteWebProgress in the parent process, so we can remove the module entirely.

Depends on D35090

The members of nsIWebProgressListener2 were added to BrowserChild (then
TabChild) in commit 1028814583232487b52b9c20d47e3b38dc1c288a, but the interface
was never added to the interface map.

Noticed some perf improvements:

Now that there is an IPDLParamTraits implementation for nsIPrincipal*, we need
not manually transform it to/form a PrincipalInfo ourselves.

https://hg.mozilla.org/mozilla-central/rev/10bef3126e1b

I'm narrowing the scope of this bug to only remove WebProgressChild (and WebProgressChild.jsm) and RemoteWebProgress + RemoteWebProgressRequest. This leaves RemoteWebProgressManager to be replaced in another bug. That is less trivial since it requires refactoring some nsDocLoader stuff and this bug has been open and landing patches too long.
