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.
Currently only works when building with debug target. On GitHub actions
target release results in linking errors. So disable PTY for release
builds.
Part of #25.
If disable_pty=yes then the PTY node and dependencies (LibuvUtils, Pipe)
will be excluded. On platforms where the PTY node is not supported (e.g.
HTML5), this will always be equivalent to `disable_pty=yes`.
Uses fork of node-pty native code for forking pseudoterminals.
Uses libuv pipe handle to communicate with the child process.
- Paves the way for cross-platform (Linux, macOS and Windows) support.
- Renames Pseudoterminal to PTY (which is much easier to type and spell :D).
- Better performance than the old Pseudoterminal node. Especially when
streaming large amounts of data such as running the `yes` command.
- Allows setting custom file, args, initial window size, cwd, env vars
(including important ones such as TERM and COLORTERM) and uid/gid
on Linux and macOS.
- Returns process exit code and terminating signal.
- Uses matrix so that build steps don't need to be defined multiple
times.
- Caches godot-cpp bindings, so they only need to be built when the
submodule version changes.
- Uploads build artifacts for linux 32/64-bit, windows 64-bit and macOS
64-bit.
