The names were confusingly similar, but _srt_util_set_up_logging() was actually orthogonal to pv_set_up_logging(): the former was about the disposition of the stdout and stderr fds, whereas the latter was about the GLib log handler. Rename it to make the difference clearer. Signed-off-by:

PreloadModule is no longer used in pv-adverb, because we needed a different data structure there. Do a similar transformation here. This turns it inside out: instead of what's conceptually map<variable=LD_AUDIT or LD_PRELOAD, values=array<string>> we now have array<struct<variable=LD_AUDIT or LD_PRELOAD, string>> which is a bit easier to deal with in practice.

I think this makes it a bit clearer what's going on: we populate one list (currently a PreloadModule[]) from the command-line options, then translate it to form a second list (in -wrap it's a plain GPtrArray, in -adverb it's implicit in the environment variables we're setting). Signed-off-by:

When a game is launched with the Steam Overlay feature enabled (it's on by default), we end up with an LD_PRELOAD that contains `gameoverlayrenderer.so` two times, one for 32-bit and the other for 64-bit processes. However this leads to a warning that is harmless but scary for users and developers unaware of that: `ERROR: ld.so: object '/home/me/.local/share/steam/ubuntu12_64/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS64): ignored.` And every 64-bit process prints something similar about the ELFCLASS32. By creating a temporary directory and using the dynamic linker token expansion `$PLATFORM` we can let a process preload only the `gameoverlayrenderer.so` for the right ABI. Signed-off-by:

These indicate which lines are harmless and which lines are really bad, without taking up too much space. The mapping from GLib log level to message is not 100% obvious, because G_LOG_LEVEL_ERROR is "worse than" an error. We diagnose "can't happen" situations (assertion failures, etc.) as "Internal error". Ideally, users should never see these: they indicate a bug. For situations that will cause pressure-vessel to exit with an error, introduce a new log level flag PV_LOG_LEVEL_FAILURE and map it to the apt-style "E:" prefix. pv_log_failure() is a convenience macro to log at level PV_LOG_LEVEL_FAILURE. Conceptually this is a fatal error, but it's a fatal error prompted by something external to pressure-vessel, for which we want pressure-vessel to clean up "nicely" and exit gracefully, even though it's going to fail - so we can't use g_error() for this. In the parts of main() that involve parsing command-line arguments, add usage_error() as syntactic sugar for pv_log_failure(). I might eventually turn these into G_OPTION_ERROR_FAILED as we factor out more of main() into helper functions, but for now they're handled separately. For less-severe log levels, use single-letter prefixes similar to apt's. Signed-off-by:

Because we were testing for a prefix match with a trailing slash, when FlatpakExports exports /home/me, we would not rewrite it to /home/me/.var/app/com.valvesoftware.Steam. Instead of adding the necessary special cases, use a slightly refactored version of flatpak_has_path_prefix(), which already does what we need. Signed-off-by:

Now that GIO_MODULE_DIR has been backported into scout's GLib, we can disable GIO modules completely, instead of loading them but then not using them. This avoids some misleading warnings (#32). This will not be completely effective on non-Debian systems until we also patch scout's GLib to make GIO_MODULE_DIR take precedence over the hard-coded legacy search path /usr/lib/gio/modules. The unit test for this is still in tests/pressure-vessel/utils.c for now. Signed-off-by:

pressure-vessel had a few hard coded assumptions about the host system and where to look at for the graphics provider. For example it was assumed that the root was the same host system used by both pressure-vessel current environment (where pressure-vessel-wrap runs) and also later on by `bwrap`. But when we run pressure-vessel in a Flatpak container, the final `bwrap` command is expected to be executed against the real host system (mounted in `/run/host`, in Flatpak). Also when we are in a Flatpak container we might want to pick the graphics stack from the host system (`/run/host`), from the Flatpak container itself or it could even be a completely separate one.

This will let us duplicate a runtime and edit it in-place. The major appeal of doing this is that it's something we can do in a Flatpak environment, where recursively invoking bubblewrap isn't allowed. It also seems like it might yield a more reliable way to overwrite parts of the runtime with their host-system equivalents than the tricks we currently use with files and directories mounted over their runtime counterparts. The major down side is that after we've done this, we have a copy of the runtime, which we need to garbage-collect and clean up eventually. Signed-off-by:
