Commit message

Pass on the owning Session when creating Surfaces.

Description of the change

This branch exposes the owning Session when creating Surfaces.

I'm not super familiar with writing real C++11 and my use of shared_ptr may be really whack. In particular, my use of std::enable_shared_from_this means that all ApplicationSession objects must be created inside of a shared_ptr... I didn't know how else to have it pass on its "this" pointer as a shared_ptr.

Hi Michael, I'm afraid your use of shared pointers is off.

shared_ptr denotes shared ownership and, in this case the session owns the surface. It doesn't make sense for the surface to also own the session - at the very least that can create an ownership cycle (and cause a memory leak).

Having said that, as the session is guaranteed to outlive the surface I imagine an ordinary raw pointer will serve your purpose.

We should be doing something different than passing the session ptr into the surface. This establishes a weird dependency circle, I think.

from 'bug report' "But I can't seem to get access to the session that a surface is being created for."
This is somewhat by design, at the moment, a design that probably needs rethinking to suit the requirements of the shell. I think we should meet on monday to chat about what exactly is needed.

(I think that we're exposing cracks in 1) the "depth id" stacking system that ms::SurfaceStack has that might need changing)

The "scenegraph" should probably be the way to navigate from a surface to its parent session, so this might not be the best approach. OTOH it is simple and may be enough.

I think I fixed them now, please re-examine.

That aside, I had been more looking for guidance on the direction of this merge. Like, whether I should abandon this method and go a different route.

I think this route isn't the way to go as these kind of relationships tend to make testing/refactoring difficult. I am also a little worried it may be unsafe:

//

std::shared_ptr<msh::Session> session = some_session_from_somewhere();
std::shared_ptr<msh::Surface> surface = session->default_surface();
session.reset();
// Now while we do some other stuff or yield, a thread from frontend closes session causing it to be deleted (we didn't keep a reference)
LOG(surface->session()->name()); SEGFAULT!

Maybe we need to clarify "this case" - this MP simply adds a parameter without a driving test case.

Consequentially we're probably all guessing at the problem it solves.

I think the point is to make the session known at the point of building the surfaces::Surface - not long term storage. Vis:

72 + virtual std::weak_ptr<surfaces::Surface> create_surface(Session* session, SurfaceCreationParameters const& params) = 0;

Although, it isn't used in SurfaceController::create_surface() - which I would imagine is the intended consumer.

Here's my use case:
I want to change u-s-c to be able to place a specified user session under the greeter session, so the user session can bleed through (e.g. imagine the pin unlock screen that shows a blurred user session underneath).

Here's my current thinking on how to do so:
A) Change u-s-c to override the_surface_builder(), note which surfaces are associated with the greeter, and create those surfaces with a different depth than other surfaces (so they float above in a different layer than all other sessions).
B) Then, have lightdm tell u-s-c which session is the greeter (by naming it something like "Greeter 1") and when to raise the appropriate user session inside of its layer.

Here's the missing piece:
u-s-c can't seem to tell me that a given surface belongs to a session called "Greeter 1", so I can't create it with the right depthId. Hence this proposal.

I'm open to other ways of achieving the use case. Including some special case API like "Keep this session above these others" or "Put this session below this other one". But this MP seemed more generally useful.

And yeah, I didn't need the session pointer to be stored long term. Just needed to inspect it momentarily. So for my specific use case, eventual segfaults from storing it is not as much a problem.

Robert's concerns are valid in that we don't want the chance of the session being invalid but the surface object still existing. Can we just pass the session into create_surface() as context and u-s-c can store its own mapping and take responsibility for keeping track of invalid references?

Robert's concerns relate to an existing problem to be invalid - this MP doesn't make anything worse.

+1

However, there's a related design issue here: SurfaceBuilder has a destroy() member function. This makes management of the surfaces::Surface painful - forcing shell::Surface to take a SurfaceBuilder dependency and requiring the constructor to take the Session to pass on as a parameter to pass to the corresponding create function.

Without SurfaceBuilder::destroy() shell::Surface would have no such dependency and could simply be passed the constructed surfaces::Surface from a context.

PS It might also be thought that SurfaceBuilder::destroy() is the underlying reason we have both surfaces::Surface and shell::Surface implementations - which has been the subject of several cleanup attempts.

PPS There are other MPs around that touch on this problem - basically we currently have no way to present a consistent view of our data model. (See for example, https://code.launchpad.net/~robertcarr/mir/session-transactions/+merge/175669)

To be clear, that's what this branch does, eh? I don't store the pointer anywhere, that I can see. I just pass it down through the layers, and u-s-c can do what it wants with it.

Oh duh. I must have misread the MP. Looks fine to me then

Well, when I wrote this branch, that didn't exist. :) But seriously, I don't think that would help a bunch. My brief understanding is that surfaces are assigned a DepthId at creation time. And I was wanting u-s-c to be able to set DepthId based on the Session object. If we get a signal after the fact, that seems too late for DepthId purposes.
