fix(launcher): move aerie pid/log off /tmp to the XDG ladder - #98
Merged
Merged
Conversation
aerie-launcher.sh kept its pid and log at /tmp/aerie.pid and
/tmp/aerie.log: a predictable name in a world-writable directory, so
another local user could pre-create or symlink the pid file and choose
which PID `--stop` kills (CWE-377).
Hand-fix, matching launch-scaffolder main's generator output
(standards/launcher-standard_praxis.deed):
PID ${XDG_RUNTIME_DIR:-${XDG_STATE_HOME:-$HOME/.local/state}}/launch-scaffolder/aerie/server.pid
LOG ${XDG_STATE_HOME:-$HOME/.local/state}/launch-scaffolder/aerie/server.log
start_server now creates both parent directories and sets them 0700
before the first write, and the desktop entry's tail commands quote
the log path (%q), which can now contain spaces via $HOME.

…hand-fix
The previous commit on this branch hand-edited aerie-launcher.sh onto the
XDG pid/log ladder. The /tmp paths originated in explicit pid-file and
log-file overrides in aerie.launcher.a2ml, which is still present on
main, so a later realign would have regenerated /tmp over the hand-fix.
Per the owner's ruling ("realign like siblings"), this commit deletes
those two override lines so the generator's default applies, then
regenerates the launcher with `launch-scaffolder realign`, built from
launch-scaffolder origin/main 2cb0f24 with
--standard standards/launcher-standard_praxis.deed:
PID ${XDG_RUNTIME_DIR:-${XDG_STATE_HOME:-$HOME/.local/state}}/launch-scaffolder/aerie/server.pid
LOG ${XDG_STATE_HOME:-$HOME/.local/state}/launch-scaffolder/aerie/server.log
These are the same paths the hand-fix used, so a pid file written by
either version is found by the other.
The rest of the launcher diff is the generator's current canonical
output. The metadata block moves to @launcher-deed (standard-version
0.4.0). The generator also adds ensure_state_dirs with a private-dir
check, PID validation before kill, and atomic desktop-integration
writes. Its output is shellcheck-clean.

Preserve base-generated integrations in the shell fallback.
When launch-scaffolder is unavailable or the source configuration is missing, a base-installed integration can reach the shell fallback. The base launcher has the recognised generated header, but its desktop files have no ownership marker. A copied icon also has no sidecar marker. is_managed_install therefore rejects the installation.
do_integ performs this check before the --force branch, and do_disinteg performs it before removal. Reinstall and removal both fail, including --force.
Add a shared legacy migration check for both operations. It must recognise the exact pre-marker desktop output and establish icon ownership before adding markers or removing files. Do not accept the launcher marker as ownership proof for arbitrary companion files.

What changed and why
aerie-launcher.shkept its pid and log at/tmp/aerie.pidand/tmp/aerie.log. That is a predictable name in a world-writable directory. Another local user could pre-create or symlink the pid file and so choose which PID--stopkills (CWE-377 class). launch-scaffolder#63 records that this path is no longer standard-compliant.The launcher is now realigned from its config, the same way as the sibling launchers (game-server-admin, nqc, panll). This PR has two commits; the second one supersedes the first:
af81a74: a hand-fix of the two path lines. It is fully replaced by commit 2.b19446f, following the owner's ruling "realign like siblings":/tmpoverrides fromaerie.launcher.a2ml(pid-file = "/tmp/aerie.pid",log-file = "/tmp/aerie.log"), so the generator's default applies.aerie-launcher.shwithlaunch-scaffolder realign, built from launch-scaffolderorigin/main2cb0f24 with--standard standards/launcher-standard_praxis.deed.The regenerated paths:
The earlier caveat is resolved. The config no longer carries
/tmpoverrides, so a laterrealignwalk reproduces this file instead of writing/tmpback over it.Realign ran inside an
unshare -rmnamespace with the worktree bind-mounted at the config's[repo].path. That way the bakedCONFIG_FILEis the canonical/var/mnt/eclipse/repos/aerie/aerie.launcher.a2ml, not a scratch path.Scope of the generator diff. Everything beyond the two paths is the generator's current canonical output:
@launcher-deed(standard-version 0.4.0);ensure_state_dirscreates the state directories0700and refuses a non-private directory;kill;A known generator quirk also shows up: a duplicated SPDX header line. That quirk is the same in the sibling PRs.
