Historically this method short-circuited when the flag file was absent, which left ssa-agent.service running via socket activation whenever the flag file had been deleted out-of-band (CLPRO-3076). We now always reconcile real state: stop+disable the agent service AND its socket, remove any clos_ssa.ini files present, and clear the flag file if it exists. Inconsistency between the flag file and the runtime state is logged as a warning so future drift can be traced. Ordering: ``stop_ssa_agent`` runs **first**, so a later failure (e.g. ini removal raising on a filesystem error) cannot leave the OOM-prone daemon running — stopping the agent is the core guarantee this method exists to provide. - stop+disable SSA Agent service and ssa-agent.socket - remove clos_ssa extension for each PHP version on server - remove clos_ssa extension from cagefs for each user and each ver - remove flag_file indicating that SSA is enabled :return: JSON encoded current status activeupdisable_ssa: inconsistent state — flag file %s is missing but ssa-agent is active; reconciling from real state disable_ssarrr)r agent_activertNrH)rr) rUstatus_ssa_agentrr|r stop_ssa_agentremove_clos_inis remove_flagr:rDrur)r'rrrxs r(rzManager.disable_ssas3.m ,,..(:  |  K  G        ! ! !  ! ! # # #           KK,7GyyZ)!ff       9+5]YYS]lx    ""$$$s.s0ZZZzsE3E ((**ZZZr*rr)rversionr? agent_status autotracing)r r<rQrrUrr get_stats)r'_configs r(rzManager.get_statss[Z=O=Q=Q=W=W=Y=YZZZ}}MM $ =99:..00" ..00    r*dir_pathc t|S)z= Check if directory path should be excluded. )r )r'rs r(unused_dir_pathzManager.unused_dir_path's )))r*php_rootpatternsc|D]E}tj||}tj|r|cSF|r&tj||dndS)z Search for clos_ssa.so module in php_root using a list of patterns.

Stopping the service alone is not enough on systemd, for two reasons: * ``ssa-agent.socket`` keeps listening and will re-spawn the service the moment a PHP worker writes to /opt/alt/clos_ssa/run/ssa.sock. * ``ssa-agent.service`` is shipped *enabled* (``WantedBy=multi-user.target``) and pulls the socket back up via ``Requires=ssa-agent.socket`` on the next boot — so a plain stop reverts at reboot, and the agent's periodic ssa.db maintenance can OOM again (CLPRO-3076 / CLPRO-3077). We therefore stop *and disable* both units. ``disable`` only removes boot-time wants symlinks, so it is what makes the change persistent; disabling the socket also prevents socket-activation from starting a disabled service (``disable`` does not block socket activation on its own). ``enable_ssa`` re-enables the service via ``start_ssa_agent``. Belt-and-suspenders ordering: 1. **Socket-first** stops socket activation so nothing can spawn a fresh agent process between the service stop and our own socket stop (closes a narrow race window). The ``run_systemctl`` helper is best-effort and never raises. 2. **try/finally** around the service-utility calls re-asserts the full stop+disable of *both* units on the failure path, so if ``run_service_utility`` throws ``SSAManagerError`` (e.g. systemd stop timeout, ``/sbin/service`` missing) the unit cleanup still runs — guaranteeing the CLPRO-3076 fix even on degraded systems. The fallback ``stop`` goes through ``/bin/systemctl`` (a different binary from ``/sbin/service``), so it can succeed where the primary stop failed. stopzssa-agent.socketdisabler?TrrNrrs r(rzManager.stop_ssa_agent#s9H 6#5666 9&8999 ?33H==L* E((t(DDD   v'9 : : :   v': ; ; ;   y*< = = =   y*= > > > > >   v'9 : : :   v': ; ; ;   y*< = = =   y*= > > > >s 3B;;ADcZ |ddn#t$rYdSwxYwdS)z: Get SSA Agent status: active or inactive r?Trinactiver)ryr r&s r(rzManager.status_ssa_agent[sJ   $ $XT $ B B B B   :: xs  ((cttd5 dddn #1swxYwY|jdtddS)zE Create a flag file indicating successful enablement rN Flag file z created)rr rr=r&s r(rzManager.create_flages)S ! !                   9i999:::::s $((c tjt|jdtddS#t $r0}|jdtd|Yd}~dSd}~wwxYw)z: Remove a flag file indicating enablement rz removedz removal failed: N)r5rr rr=r!r|)r'rxs r(rzManager.remove_flagms P Ii K  =)=== > > > > > P P P K   NY N N N N O O O O O O O O O Psrs   %%%%%%"""""" EDDDDDDD))))))000000''''''******111111 p \p \p \p \p \p \p \p \fr*
