Use sockets for IPC (#2539)
Deprecates not using `polybar-msg` for IPC.

Fixes #2532
Closes #2465
Fixes #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

Allow running polybar without BAR argument (#2526)
* Allow running polybar without BAR argument

The configuration file must declare a single bar to be able to not name
it.

* Check barname not in config and improve error message

* Revert README changes

* Add no bar in config file error detection

script: Fix concurrency issues (#2518)
Fixes #1978

* Move tail and non-tail handler to method

Defining them in the constructor is ugly.

* script: Iterate over defined actions instead of fixed list

* Separate running logic and lock m_output

* Include POLYBAR_FLAGS in linker flags

* Stop using m_prev in script_runner

* Join module threads in stop function

Joining in the destructor may lead to UB because the subclass is already
deconstructed but the threads may still require it to be around (e.g.
for calling any functions on the instance)

* Cleanup script module

* Update changelog

* Remove AfterReturn class

* Remove m_stopping from script module

* Fix polybar not reading the entire line from child process.

For every `readline` call we created a new fd_streambuf. This means once
`readline` returns, the streambuf is destructed and and pending data in
its temporary buffer discarded and we never actually read it.

* Remove unused includes

626c55f8e5 Template value type for get_with_prefix 2021-09-28 22:16:07 +02:00
TheDoctor314
1e0e50266b Add get_with_prefix()
Returns a list of key-value pairs starting with a prefix.
If you have in config:
```
env-FOO = bar
env-CAT = dog
```

then `get_with_prefix("env-")` will return
`[{"FOO", "bar"}, {"CAT", "dog"}]`

dd4088910e Deprecate throttle-output and throttle-output-for
The eventloop no longer uses them. libuv will coalesces multiple
uv_async_send if they happen one after another and this also leads to
coalescing of updates.

91759a4c96 Store all handles inside eventloop
This is needed because the handle's lifetime has to be at least the
lifetime of the eventloop since the eventloop requires the handle's
memory during shutdown (for closing the handles).

Universal Visibility Action (#2320 cont'd) (#2426)
* Add toggle_visible action

* Add set_visible and set_invisible actions

* Rename toggle_visible method to match

`action_toggle_visible` -> `action_toggle_visibility`

Matches with `EVENT_TOGGLE_VISIBILITY`

* Update CHANGELOG

* Revert #2320 IPC commands

IPC commands are no longer necessary now that the actions are
implemented. Changed some method permissions as well to reflect this.

* Add logging and change action names

- `module_toggle`
- `module_show`
- `module_hide`

Delineate common actions to all modules with a `module_` prefix (for
future actions too)

* Update documentation

96239597ed Move most action state out of renderer
The renderer now only stores the positions of the actions because that
is specific to the renderer and because the actual position can only be
finalized after all the rendering is done because intitially the
positions are relative to the alignment and not the bar.

0a474bb2f2 Move trivial formatting state into tags::context
The variables storing the current colors, attribute activations and font
were only used in a single place and can easily also be read from the
context.

This allows us to remove a lot of the state of the renderer.
