If the root pixmap does not fully cover the bar window, some
pseudo-transparent areas were filled with unitialized data, causing
pixelation or other rendering artifacts.
Now, ovserved background slices are first filled with black to make sure
this does not happen and they print an error if not the full pixmap can
be filled.
Fixes#3041
Without override-redirect, i3 will not allow you to have a
non-full-width bar. But polybar simply ignores that request and
continues to render the user-requested width instead of the width i3 has
configured the window to be.
With the 3.7 release, we started setting the window's backing pixmap to
the rendering pixmap. In the case above, the pixmap would only be
allocted for the smaller width and when i3 maps the window, it repeats
the backing pixmap to fill the entire window.
At the point where i3 maps the window, the pixmap contains an initial
render of the bar without module content and that render is then
duplicated.
Reverting back to the old approach of simply copying over the pixmap
after each render does not have that problem and the remainder of the
bar is black (or fully transparent with a compositor).
Ideally, polybar would respect the width i3 configures for it, but that
would break many existing setups that rely on non-full-width bars in i3
Fixes#3060
* Return shared_ptr from eventloop
* Add -Wdeprecated-copy-dtor warning
Produces a warning if classes don't have explicit copy operations if
they have a user-defined constructor.
This helps us stick to the rule of 5 (kinda, no warnings for missing
move operators).
* Clean up eventloop
* Fix compiler warnings
* Fix fs_event_handle_t name
Deprecates not using `polybar-msg` for IPC.
Fixes#2532Closes#2465Fixes#2504
* Create FIFO specific NamedPipeHandle subclass to PipeHandle
* Prototype SocketHandle
* Move mainloop up to main.cpp
* Pass eventloop to ipc class
* Deprecate sending ipc over the named pipe
Unfortunately, we can only show the warning in the polybar log and not
give the user any feedback because the pipe is one-way
* Move eventloop into its own namespace
* Prototype ipc socket handling
* Remove handles from ipc_client
Should be independent from eventloop logic
* Remove ipc clients when finished
* Add tests for ipc_client decoding
* Add callback for complete ipc messages
* Remove template param from mixins
* Move signal handler to new callback system
* Move poll handle to new callback system
* Move FSEventHandle to new callback system
* Move TimerHandle and AsyncHandle to new callback system
* Move PipeHandle to new callback system
* Implement socket functionality in new callback system
* Correctly reset ipc named pipe handle
* Let client close handles in error callback
* Wrap client pipe and ipc::client in connection class
* Better decoder log messages
* Socket path logic
* Fix CI warnings
* Remove UVHandleGeneric
* Fix error when socket folder already exists
* Proof of concept message writeback
* Restructure ipc files
* polybar-msg: Use sockets
* polybar-msg: Better syntax for actions
* Fix memory leak with fifo
After EOF, the pipe wasn't closed and EOF was called all the time, each
time allocating a new pipe.
* Make polybar-msg compile on its own
* Rudimentary writeback for polybar-msg
* Fix payload reference going out of scope.
* Add IPC documentation
* Cleanup polybar-msg code
* Specify the v0 ipc message format
* Close ipc connection after message
* Fix ipc tests
* Properly close ipc connections
* Fix polybar-msg not working with action string
* Write polybar-msg manpage
* polybar-msg: Stop using exit()
* ipc: Print log message with PID
* Add tests for ipc util
* polybar-msg: Print PID with success message
* ipc: Propagate message errors
* Rename ipc::client to ipc::decoder
* Rename ipc.cpp to polybar-msg.cpp
* ipc: Write encoder function and fix decoder bugs
* ipc: Use message format for responses
* ipc: Handle wrong message types
* ipc: Write back error message if ipc message cannot be processed
This only happens for commands and empty actions.
Non-empty actions are not immediately executed, but deferred until the
next loop iteration.
* Remove TODO about deleting runtime directory
The socket file is not deleted after socket.close() is called, only
after libuv executes the close callback.
So we can't just call rmdir because it will probably always fail.
* CLeanup WriteRequest
* Update manpage authors
* Cleanup
