Marien Zwart ffd1308bbc Fix crash when destroying an idle-inhibiting client

Ryan Dwyer 9215ca0f01 Align titles to baseline
This does the following:

* Adds a baseline argument to get_text_size (the baseline is the
distance from the top of the texture to the baseline).
* Stores the baseline in the container when calculating the title
height.
* Takes the baseline into account when calculating the config's max font
height.
* When rendering, pads the textures according to the baseline so they
line up.

Ryan Dwyer 9226aad58c Fix gaps in title textures and vertically center them
There was code that attempted to fill in the gap below the title texture
when the texture isn't tall enough, but this only worked when the output
was positioned at 0,0. The reason is that render_rect expects a box
passed in a hybrid layout-local/output-buffer-local system, and we were
passing purely output-buffer-local. I've added a comment documenting
this.

By the way, we can't use layout-local coordinates for the rectangle box
because in some cases we set the box based on a texture size. Texture
sizes are buffer-local, and we'd have to divide them to bring it back to
layout-local which means losing precision. We could use
output-buffer-local coordinates for the box, but this would require
translating the coordinates from layout-local to output-buffer-local in
many places during rendering.

This patch also vertically centers the text inside the title bar.

Ryan Dwyer 5967ee1fbc Fix crash when switching to new workspace during transaction
When rendering, the workspace for the output needs to be retrieved from
the output's `current` state. output_get_active_workspace returns the
pending workspace, which crashes if the pending workspace is new and
hasn't completed a transaction yet.

Ryan Dwyer 9642b87b9e Fix crash when views rapidly map and unmap
Suppose the following:

* Transactions are already in progress - say transaction A.
* View A maps, which creates transaction B and appends it to the
transaction queue.
* View B maps, which creates transaction C and appends it to the queue.
* View A unmaps, which creates transaction D and appends it to the
queue.
* Transaction A completes, so transaction B attempts to save View A's
buffer, but this doesn't exist so it saves nothing.
* Rendering code attempts to render View A, but there is no saved buffer
nor live buffer that it can use.

Rather than implement an elaborate solution for a rare circumstance,
I've take the safe option of just not rendering anything for that view.
It means that if you reproduce the scenario above, you might get the
title and borders rendered but no surface.

Ryan Dwyer 7586f150c0 Implement type safe arguments and demote sway_container
This commit changes the meaning of sway_container so that it only refers
to layout containers and view containers. Workspaces, outputs and the
root are no longer known as containers. Instead, root, outputs,
workspaces and containers are all a type of node, and containers come in
two types: layout containers and view containers.

In addition to the above, this implements type safe variables. This
means we use specific types such as sway_output and sway_workspace
instead of generic containers or nodes. However, it's worth noting that
in a few places places (eg. seat focus and transactions) referring to
them in a generic way is unavoidable which is why we still use nodes in
some places.

If you want a TL;DR, look at node.h, as well as the struct definitions
for root, output, workspace and container. Note that sway_output now
contains a workspaces list, and workspaces now contain a tiling and
floating list, and containers now contain a pointer back to the
workspace.

There are now functions for seat_get_focused_workspace and
seat_get_focused_container. The latter will return NULL if a workspace
itself is focused. Most other seat functions like seat_get_focus and
seat_set_focus now accept and return nodes.

In the config->handler_context struct, current_container has been
replaced with three pointers: node, container and workspace. node is the
same as what current_container was, while workspace is the workspace
that the node resides on and container is the actual container, which
may be NULL if a workspace itself is focused.

The global root_container variable has been replaced with one simply
called root, which is a pointer to the sway_root instance.

The way outputs are created, enabled, disabled and destroyed has
changed. Previously we'd wrap the sway_output in a container when it is
enabled, but as we don't have containers any more it needs a different
approach. The output_create and output_destroy functions previously
created/destroyed the container, but now they create/destroy the
sway_output. There is a new function output_disable to disable an output
without destroying it.

Containers have a new view property. If this is populated then the
container is a view container, otherwise it's a layout container. Like
before, this property is immutable for the life of the container.

Containers have both a `sway_container *parent` and
`sway_workspace *workspace`. As we use specific types now, parent cannot
point to a workspace so it'll be NULL for containers which are direct
children of the workspace. The workspace property is set for all
containers, except those which are hidden in the scratchpad as they have
no workspace.

In some cases we need to refer to workspaces in a container-like way.
For example, workspaces have layout and children, but when using
specific types this makes it difficult. Likewise, it's difficult for a
container to get its parent's layout when the parent could be another
container or a workspace. To make it easier, some helper functions have
been created: container_parent_layout and container_get_siblings.

container_remove_child has been renamed to container_detach and
container_replace_child has been renamed to container_replace.

`container_handle_fullscreen_reparent(con, old_parent)` has had the
old_parent removed. We now unfullscreen the workspace when detaching the
container, so this function is simplified and only needs one argument
now.

container_notify_subtree_changed has been renamed to
container_update_representation. This is more descriptive of its
purpose. I also wanted to be able to call it with whatever container was
changed rather than the container's parent, which makes bubbling up to
the workspace easier.

There are now state structs per node thing. ie. sway_output_state,
sway_workspace_state and sway_container_state.

The focus, move and layout commands have been completely refactored to
work with the specific types. I considered making these a separate PR,
but I'd be backporting my changes only to replace them again, and it's
easier just to test everything at once.

Ryan Dwyer dce549c537 Don't send never-ending transactions when a focused layer surface commits
This moves the arrange_windows call into the arrange_layers function,
where we know the output actually needs to be arranged.

Additionally, we shouldn't set focus to the parent of an unknown
container type, because the parent may be an output and this causes a
crash because outputs can't have direct focus.

Ryan Dwyer 53fe7b02e9 Fix workspace tabs

Ryan Dwyer b12f7be907 Don't use bitfield to test for similar transactions
When there's multiple transactions in the queue, sway can take a
shortcut by checking if they all operate on the same set of containers.
If they do, it can skip all but the last transaction. The way we tested
for transactions which used the same containers was to exclusive-or
their con IDs together, but this has proved not only to be ineffective
but also has the potential to make sway crash.

This patch replaces the exclusive-or with a loop and container
comparison.

Ryan Dwyer f5b9815128 Prepare arrange code for type safe arguments
This commit changes the arrange code in a way that will support type
safe arguments.

The arrange_output et al functions are now public, however I opted not
to use them directly yet. I've kept the generic arrange_windows there
for convenience until type safety is fully implemented. This means this
patch has much less risk of breaking things as it would otherwise.

To be type safe, arrange_children_of cannot exist in its previous form
because the thing passed to it could be either a workspace or a
container. So it's now renamed to arrange_children and accepts a list_t,
as well as the parent layout and parent's box.

There was some code which checked the grandparent's layout to see if it
was tabbed or stacked and adjusted the Y offset of the grandchild
accordingly. Accessing the grandparent layout isn't easy when using type
safe arguments, and it seemed odd to even need to do this. I determined
that this was needed because a child of a tabbed container would have a
swayc Y matching the top of the tab bar. I've changed this so a child of
a tabbed container will have a swayc Y matching the bottom of the tab
bar, which means we don't need to access the grandparent layout.  Some
tweaks to the rendering and autoconfigure code have been made to
implement this, and the container_at code appears to work without
needing any changes.

arrange_children_of (now arrange_children) would check if the parent had
gaps and would copy them to the child, effectively making the
workspace's gaps recurse into all children. We can't do this any more
without passing has_gaps, gaps_inner and gaps_outer as arguments to
arrange_children, so I've changed the add_gaps function to retrieve it
from the workspace directly.

apply_tabbed_or_stacked_layout has been split into two functions, as it
had different logic depending on the layout.

Lastly, arrange.h had an unnecessary include of transaction.h. I've
removed it, which means I've had to add it to several other files.

Ryan Dwyer 5dbbab7bdc Remove layout.c
When we have type safety we'll need to have functions for
workspace_add_tiling and so on. This means the existing container
functions will be just for containers, so they are being moved to
container.c. At this point layout.c doesn't contain much else, so I've
relocated everything and removed the file.

* container_swap and its static functions have been moved to the swap
command and made static.
* container_recursive_resize has been moved to the resize command and
made static.
* The following have been moved to container.c:
    * container_handle_fullscreen_reparent
    * container_insert_child
    * container_add_sibling
    * container_add_child
    * container_remove_child
    * container_replace_child
    * container_split
* enum movement_direction and sway_dir_to_wlr have been moved to util.c.

Side note: Several commands included layout.h which then included
root.h. With layout.h gone, root.h has to be included by those commands.

Ryan Dwyer 2e7401772e Rename sway_root.outputs to sway_root.all_outputs
This list includes disabled outputs.

When sway_container is demoted, we'll need to store the root's children
(ie. enabled outputs) in the sway_root. It makes sense to put these in a
list called `outputs`, so I'm renaming the existing list in advance.
2018-08-25 23:41:11 +10:00
Ryan Dwyer b6058703fa Refactor destroy functions and save workspaces when there's no outputs
This changes the destroy functions to the following:

* output_begin_destroy
* output_destroy
* workspace_begin_destroy
* workspace_destroy
* container_begin_destroy
* container_destroy
* view_begin_destroy
* view_destroy

The terminology was `destroy` and `free`, and it has been changed to
`begin_destroy` and `destroy` respectively.

When the last output is disconnected, its workspaces will now be stashed
in the root. Upon connection of a new output they will be restored.

There is a new function `workspace_consider_destroy` which decides
whether the given workspace should be destroyed or not (ie. empty and
not visible).

Calling container_begin_destroy will no longer automatically reap the
parents. In some places we want to reap the parents and in some we
don't, so this is left to the caller.

container_reap_empty_recursive and container_reap_empty have been
combined into one function and it will recurse up the tree.

Merge pull request #2483 from RyanDwyer/floating-emit-reparent
Send enter/leave events for floating views
2018-08-19 22:06:09 -04:00
Ryan Dwyer 0f6d212629 Send output enter/leave events correctly
Previously we used a reparent event to detect when a view changes
parent, then sent an output enter/leave to the surfaces if needed. This
worked for tiling views but not floating views, as floating views can
intersect another output without changing parent.

The solution implemented for floating views also applies cleanly to
tiling views, so the previous method has been completely replaced and
the reparent event has been removed.

This introduces a new function container_discover_outputs. This function
compares the container's `current` position to the outputs, sends enter
and leave events as needed, and keeps track of which outputs it's
intersecting in a new `container->outputs` list. If it has entered a new
output with a different scale then the title and marks textures will
also be recreated at the new scale.

The function is called when a transaction applies. This is convenient as
it means we don't have to call it from various places.

There is imperfect rendering when a floating view overlaps two outputs
with different scales. It renders correctly for the most recently
entered output, but there is only one title texture so it renders
incorrectly on the old output.

Ryan Dwyer b3e2c49774 Fix crash when a view destroys with pending transactions
We were removing the saved buffer when one transaction applies, then
didn't have a new buffer to save when the next transaction ran. This
made the rendering code crash as it had no surface to use.

This commit makes it continue to hold the buffer if the view is
destroying and has more transactions. Additionally, a check is added
when saving the buffer to make sure there's no one already there.

Ryan Dwyer 2b5a404ac9 Replace hacky L_FLOATING container with a list
Workspaces previously had a magical `workspace->floating` container,
which had a layout of L_FLOATING and whose children were actual floating
views. This allowed some conveniences, but was a hacky solution because
the container has to be exempt from focus, coordinate transactions with
the workspace, and omit emitting IPC events (which we didn't do).

This commit changes it to be a list directly in the sway_workspace. The
L_FLOATING layout is no longer used so this has been removed as well.

* Fixes incorrect check in the swap command (it checked if the
containers had the L_FLOATING layout, but this layout applied to the
magical container).

* output_find_container
* workspace_find_container
* container_find_child

This fixes a race condition flicker when unfloating a view which uses

When the view is floated it has using_csd = true, so the decorations are

wasn't part of transactions so it could potentially render the
decorations around the view while it's waiting for the transaction to
apply.

Ryan Dwyer c3ef36d6b5 Simplify transactions
Commit 4b8e3a885b makes it so only one
transaction is committed (ie. configures sent) at a time. This commit
removes the now-unnecessary code which was used to support concurrent
committed transactions.

* Instead of containers storing a list of instructions which they've
been sent, it now stores a single instruction.
* Containers now have an ntxnrefs property. Previously we knew how many
references there were by the length of the instruction list.
* Instructions no longer need a ready property. It was used to avoid
marking an instruction ready twice when they were in a list, but this is
now avoided because there is only one instruction and we nullify the
container->instruction pointer when it's ready.
* When a transaction applies, we no longer need to consider releasing
and resaving the surface, as we know there are no other committed
transactions.
* transaction_notify_view_ready has been renamed to
view_notify_view_ready_by_serial to make it consistent with
transaction_notify_view_ready_by_size.
* Out-of-memory checks have been added when creating transactions and
instructions.

Ryan Dwyer 8314019f66 Fix race condition crashes when unmapping views
This fixes two issues which were both introduced in #2396.

First issue:
The PR changes the location of the buffer save to transaction_apply, but
puts it inside the should_configure block. For unmapping (destroying)
views, should_configure returns false so it wasn't saving the buffer. If
a frame was rendered between the unmap and the transaction applying then
it would result in a crash.

Second issue:
If a destroying view is involved in two transactions, we must not
release the buffer between the transactions because there is no live
buffer to grab any more.

Ryan Dwyer d10ccc1eb1 Correctly track saved surfaces during multiple transactions
Fixes #2364.

Suppose a view is 600px wide, and we tell it to resize to 601px during a
resize operation. We create a transaction, save the 600px buffer and
send the configure. This buffer is saved into the associated
instruction, and is rendered while we wait for the view to commit a
601px buffer.

Before the view commits the 601px buffer, suppose we tell it to resize
to 602px. The new transaction will also save the buffer, but it's still
the 600px buffer because we haven't received a new one yet.

Then suppose the view commits its original 601px buffer. This completes
the first transaction, so we apply the 601px width to the container.
There's still the second (now only) transaction remaining, so we render
the saved buffer from that. But this is still the 600px buffer, and we
believe it's 601px. Whoops.

The problem here is we can't stack buffers like this. So this commit
removes the saved buffer from the instructions, places it in the view
instead, and re-saves the latest buffer every time the view completes a
transaction and still has further pending transactions.

As saved buffers are now specific to views rather than instructions, the
functions for saving and removing the saved buffer have been moved to
view.c.

The calls to save and restore the buffer have been relocated to more
appropriate functions too, favouring transaction_commit and
transaction_apply rather than transaction_add_container and
transaction_destroy.

Ryan Dwyer de86d65627 Fix popups
Fixes the render and container_at order for popups.

Fixes #2210

For rendering:

* render_view_surfaces has been renamed to render_view_toplevels
* render_view_toplevels now uses output_surface_for_each_surface (which
is now public), as that function uses wlr_surface_for_each_surface which
doesn't descend into popups
* Views now have a for_each_popup iterator, which is used by the
renderer to render the focused view's popups
* When rendering a popup, toplevels (xdg subsurfaces) of that popup are
also rendered

For sending frame done, the logic has been updated to match the
rendering logic:

* send_frame_done_container no longer descends into popups
* for_each_popup is used to send frame done to the focused view's popups
and their child toplevels

For container_at:

* floating_container_at is now static, which means it had to be moved
higher in the file.
* container_at now considers popups for the focused view before checking
containers.
* tiling_container_at has been introduced, so that it doesn't call
container_at recursively (it would check popups recursively if it did)

Allow containers to float
2018-07-28 09:30:12 -04:00
Ryan Dwyer 08cfba2192 Allow containers to float
Things worth noting:

* When a fullscreen view unmaps, the check to unset fullscreen on the
workspace has been moved out of view_unmap and into container_destroy,
because containers can be fullscreen too
* The calls to `container_reap_empty_recursive(workspace)` have been
removed from `container_set_floating`. That function reaps upwards so it
wouldn't do anything. I'm probably the one who originally added it...
* My fix (b14bd1b0b1) for the tabbed child
crash has a side effect where when you close a floating container, focus
is not given to the tiled container again. I've removed my fix and
removed the call to `send_cursor_motion` from `seat_set_focus_warp`. We
should consider calling it from somewhere earlier in the call stack.

Ryan Dwyer 52cf410d3c Second attempt at fixing transaction use-after-free
The solution used in 073ac425d5 doesn't
work in all cases because the freed instruction might be ahead in the
list, not necessarily behind.

The new solution delays running the queue until after the loop has
finished iterating, thus avoiding the problem completely.
2018-07-28 17:43:18 +10:00
Ryan Dwyer 073ac425d5 Fix use after free in transactions
In set_instructions_ready, calling set_instruction_ready may cause any
number of transactions to get applied, which removes them from the list
being iterated.  The iteration variables need to be adjusted
accordingly.
