 Dandellion | seems a little weird to be doing schema upgrades as a "low priority" task in the background if they block worker | 00:14:36 |

| hexa | I know what this is 😭 | 00:16:05 |
| hexa | no dependency resolution when you go systemctl restart matrix-synapse matrix-synapse-worker-client1 [...] | 00:17:56 |
| Dandellion | and I assume that's what nixos-rebuild does | 00:18:21 |
| hexa | bingo | 00:18:26 |
| hexa | so we'll likely need a prestart script that waits for matrix-synapse to be ready 🙂 | 00:18:32 |
| Dandellion | I think I actually came to this conclusion a year ago when you mention it | 00:18:47 |
| Dandellion | 😬 | 00:19:05 |
| hexa | yeah, so much knowledge gets lost over time | 00:19:13 |

no dependency resolution when you go systemctl restart matrix-synapse matrix-synapse-worker-client1 [...] that's cursed... | 00:35:53 |
| f0x | oh could be an interesting workaround, ExecStartPost= restart the workers again | 00:37:59 |
| f0x | or use that to start the workers in the first place, maybe | 00:38:18 |
| hexa | my worst idea for this is to use dbus-monitor 😛 | 00:42:23 |
| hexa | # systemctl show -p SubState --value matrix-synapse
start-pre
| 00:55:27 |
| hexa | # systemctl is-active matrix-synapse
activating
| 00:55:54 |
| hexa |
is-active PATTERN…
Check whether any of the specified units are active (i.e. running). Returns an exit code 0 if at least one is active, or non-zero otherwise. Unless --quiet is specified, this will also print the current unit state to standard output

no dependency resolution when you go systemctl restart matrix-synapse matrix-synapse-worker-client1 [...] you can tell switch-to-configuration to stop and start instead of restart, that might work. | 13:30:55 |
| hexa | I think I have more confidence in a loop with in-active in prestart | 13:34:06 |
| hexa | Wondering when exactly systemd handles dependencies, possibly inside targets? | 13:35:05 |
| @andreas.schraegle:helsinki-systems.de | das_j isn't here, he might be able to tell you | 13:37:56 |
| hexa | a quick brainstorming how worker definitions could be looking: https://md.darmstadt.ccc.de/synapse-at-work?both | 22:57:50 |
| hexa | more input welcome | 22:57:56 |
| hexa | * more input very welcome | 22:57:58 |
| f0x | added some more assertions | 23:43:07 |
