Fixes error that would sometimes occur when closing the Terminal after
calling write() but before the VisualServer had finished drawing the
current frame.
De-references pty_baton's exit callback after it is called so it can be
automatically released, preventing leaked instances.
Adds basic implementation for Pipe's get_status() method and forces PTY
to wait for child process to exit to ensure exit callback is cleaned up.
Adds a test to check that exit callback is still called as usual.
The type of winsize.ws_col and winsize.ws_row is unsigned short, so
change python's struct.unpack format from 'hh' (short) to 'HH'.
Otherwise, we can only test sizes up to 32767 when actually sizes up to
65535 are supported.
Commit GUT directly to the git repo and remove gd-plug as it is no
longer required to install GUT.
Modify GUT to be used by command-line only.
For example:
```
cp test/.gutconfig.ci.json .gutconfig.json
godot --no-window -s addons/gut/gut_cmdln.gd
```
Often when closing a terminal in the terminal panel the error message
'Condition "!obj" is true.' would be printed to console.
This was due to the call_funcv() method being called on an invalid
FuncRef instance (invalid because it had already been deleted or queued
for delection).
Now we check the instance is valid before calling the method.
There is no current public use for this type and it would appear in every
resource dropdown.
While this type is no longer exposed publically by the plugin it is still
used internally by terminal_panel.
Adds support for building Linux binaries inside a docker container in
order to target an older version of GLIBC.
Updates GitHub Actions workflow to use it.
As a result the minimum version of GLIBC that Linux users need to have
installed on their system is 2.17 which was released in 2012.
- windows-latest now uses windows-2022 which has Visual Studio 17 2022.
- Update cmake version from 3.15.4 to 3.23.2 which has generator for the
newer version of Visual Studio.
Updates the godot-cpp submodule to a version which supports universal macOS
builds.
- We now need to include the standard string in terminal.cpp.
- Clean-up .gitmodules while we're at it.
Makes for pretty paths when extending scripts:
`extends "res://addons/godot_xterm/terminal.gd"`
vs.
`extends "res://addons/godot_xterm/nodes/terminal/terminal.gd"`
Currently "res://addons/godot_xterm/pty.gd" is acutally `pty_unix.gd`.
This is okay for now as the PTY node is only supported on Unix
platforms. However, we will need to sort it out when adding Windows
support as part of #25.
Also remove the GDXterm namespace.
