libglnx is the successor to libgsystem: https://git.gnome.org/browse/libgsystem
It is for modules which depend on both GLib and Linux, intended to be used as a git submodule.
Features:
- File APIs which use
openat()like APIs, but also take aGCancellableto support dynamic cancellation - APIs also have a
GErrorparameter - High level "shutil", somewhat inspired by Python's
- A "console" API for tty output
- A backport of the GLib cleanup macros for projects which can't yet take a dependency on 2.40.
There are multiple projects which have a hard dependency on Linux and GLib, such as NetworkManager, ostree, flatpak, etc. It makes sense for them to be able to share Linux-specific APIs.
This module also contains some code taken from systemd, which has very high quality LGPLv2+ shared library code, but most of the internal shared library is private, and not namespaced.
One could also compare this project to gnulib; the salient differences there are that at least some of this module is eventually destined for inclusion in GLib.
For all of the filesystem access code, libglnx exposes only
fd-relative API, not GFile*. It does use GCancellable where
applicable.
For local allocation macros, you should start using the g_auto
macros from GLib. A backport is included in libglnx. There are a few
APIs not defined in GLib yet, such as glnx_autofd.
gs_transfer_out_value is replaced by g_steal_pointer.
Currently there is not a Bugzilla product - one may be created in the future. You can submit PRs against the Github mirror:
