Cooldude2606andClaude Opus 5.5 7cf9cf8d3e Unpatch saves started with save patching disabled (#1184)
* Unpatch saves started with save patching disabled

Turning factorio.enable_save_patching off did nothing to a save that
was patched before. Its control.lua still loaded every module, so the
clusterio_api interface, player_sync's join handling and the other
module event handlers kept running with no plugin on the host side.

When patching is disabled the instance now restores the original
control.lua that patching kept as scenario.lua and removes the module
files, locale files included, as listed in clusterio.json. The patch
info stays with an empty module list so the patch number keeps
counting. Otherwise patching the save again would reuse the number
stored in the game and on_server_startup would not be raised. Data
the modules put in storage is left alone.

PatchInfo.fromSave dropped the version read from the save, so the
check against newer patch versions never fired. It now keeps it.

* Remove scenario.lua when unpatching a save

Unpatching moves scenario.lua back to control.lua instead of copying it, so the save only keeps clusterio.json for the patch number. Patching such a save again copies control.lua back to scenario.lua.

bbassieandClaude Opus 5.5 f14bfc3222 Address review of template inheritance
- Unlinking a field enables Apply on its own and sends the current value.
- The link button no longer toggles the checkbox of its label.
- Link and disconnect icons for all four states, pending ones highlighted.
- instance.is_template is hidden.
- ctl create takes --as-template.
- Clearer names for the InstanceManager inheritance helpers.

bbassieandClaude Opus 5.5 b5c372f109 Rename bases to templates and add per property inheritance
Review changes for #1142:
- base becomes template everywhere (is_template, template_id,
  --template, --is-template, --templates, InstanceDetails.isTemplate).
- Object fields inherit per property. inherited_fields lists the
  overridden properties for object fields and the template object is
  merged with them.
- Linking a template also inherits fields that hold the default value.
  The server name stays per instance.
- Ports are never inherited.
- InstanceDetails carries templateId.

Web UI: inherited values are locked until unlocked, overridden values
can be inherited again, templates are listed separately, the create
modal can create templates and instances from templates, and the
instance page has "Create template" which can link the source.

bbassieandClaude Opus 5.5 01cf789f5d Add base instances for instance config inheritance
Instances can be marked as a base with instance.is_base and other
instances inherit config values from it through instance.base_id.
The controller copies base values into inheriting configs and keeps
track of inherited fields in the hidden instance.inherited_fields, so
hosts receive resolved configs and need no changes. Setting a field
stops inheriting it, `instance config inherit` undoes that.

Bases cannot be assigned to a host, are hidden from `instance list`
unless --bases is given, and cannot be deleted or unmarked while
other instances inherit from them. Chains of bases are allowed and
cycles are rejected.

bbassieandClaude Opus 5.5 37d74ca2a6 Find a full install in host.factorio_directory instead of a setting
Per review, drop host.factorio_graphics_directory. findVersion takes a
headless option that filters installs by build, telling them apart by
data/base/graphics/icons. When the instance runs the headless build the
export looks for a full install of the same major.minor version in the
host's factorio directory. Server startup is unchanged.

If none is found the export still runs, and the reason is included in
the missing icons warning.

Danielv123 46c6153201 Export without the graphics directory when it has no matching install
If host.factorio_graphics_directory had no install matching the major and
minor version of the instance, or did not exist, findVersion threw and the
whole export failed. Without the setting the same instance exports everything
except the base game icons, so it now logs a warning that names the setting
and exports without it.

Danielv123 49a0b27d29 Address review of host pairing
Revoking a host now unassigns its instances instead of being refused
while it has any, and removes its system metrics.

Approving and revoking no longer force a save. Hosts are saved by
autosave and on exit like everything else, which also removes the
approving state from pairing requests.

The approval code and link are logged as warnings so they show up in
the systemd service, which only prints warnings and above. The pairing
limits are now the controller.host_pairing_timeout and
controller.host_pairing_max_pending config values, 0 removes the limit.

Subscribers take an optional permitted function, used for the pairing
requests instead of overrides in a subclass.

Danielv123 4a49a198f0 Pair hosts when they start instead of in the installer
The installer only writes the controller URL and host name. Running the
host requests to join the cluster if it has not been approved yet, or if
the controller no longer accepts its token, and waits until an admin
approves it. Once approved it saves its id and token and starts as
normal. A rejected host exits with code 8.

clusteriohost run --user-token approves the host right away with the
token of a user allowed to approve hosts. The token is not saved.

This moves the pairing client into the host package, where it uses the
same certificate setup as the host's connection to the controller, and
removes --no-pair and the rerun handling from the installer.
2026-10-30 21:13:14 +01:00
Danielv123 87d4f5c64e Replace host tokens with host pairing
Hosts join the cluster by running the installer, which shows a code and
waits until the request is approved under Hosts > Add host in the web
interface or with clusterioctl host approve. An admin can pass their
user token to the installer to approve the host right away. The token
is only used for that and is not saved.

The controller only accepts hosts that have a record, and only
approving a host creates one. Revoking a host deletes its record, so
its token can no longer be used to reconnect. Hosts that have connected
before keep working.

Removes host generate-token, revoke-token and create-config from
clusterioctl, bootstrap generate-host-token, the host token messages and
the core.host.generate_token, revoke_token and create_config
permissions, which are also stripped from stored roles. Adds
clusterioctl host pending, approve, reject and revoke, and the
core.host.approve and core.host.revoke permissions.

Standalone installs add the host to the controller database directly,
since the controller is not running during the install.

bbassieandClaude Opus 5.5 5238a0fbb3 Report missing base game icons when exporting from headless Factorio
The headless build has no graphics, so export-data found none of the
base game's icon files. Plain icons were skipped silently and layered
icons were drawn blank and counted as exported.

Skip a layered icon when any of its layers is missing, and log one
warning with the number of base game icon files that were not found.
Add host.factorio_graphics_directory to read builtin mod graphics from
a full install when the instance runs the headless build.

bbassieandClaude Opus 5.5 11e067a933 Keep auto paused instances paused
Every RCON command makes an auto paused Factorio server run one tick, so
subspace_storage's 1 s inventory update and 5 s ping, plus a
statistics_exporter gather on every Prometheus scrape, kept a server with
nobody online running at about 1.3 ticks per second.

The instance now records the auto_pause server setting it was started
with and exposes autoPaused, true while that setting is on and no players
are online, along with an autoPauseChanged hook. subspace_storage skips
its timers while paused and sends a ping and inventory as soon as a player
joins. statistics_exporter gathers once after the game pauses and keeps
serving those values until it resumes.

bbassieandClaude Fable 5.1 8bfc42c44c Lower the Lua UDP floor to Factorio 2.1.10
Danielv123 pointed out the recv_udp crash was fixed in 2.1.10, not
2.1.12: recv_udp used an input action for synchronisation which the
headless server could not send without a player index.  Verified on
downloaded headless builds, 2.1.9 crashes and 2.1.10 works.

bbassieandClaude Fable 5.1 1f37905be0 Require Factorio 2.1.12 for Lua UDP
Factorio 2.0.59 through 2.1.11 crash with "Trying to add invalid input
action to the closure" when helpers.recv_udp dispatches a received
packet, whether polled from on_tick or called from a command and
whether or not the server is paused.  Reproduced on headless 2.0.77 and
2.1.8, works from 2.1.12 on.  FactorioServer now refuses to start with
Lua UDP enabled on older versions, the docs say 2.1.12, and the
integration tests only enable it on 2.1.12 or later.

The to-game integration test polls recv_udp from on_tick like the
clusterio module does and sends commands to make the empty server tick.

bbassieandClaude Fable 5.1 788ae17657 Add UDP communication support for instances
Add opt-in UDP messaging between the host and the Factorio server using
the --enable-lua-udp option of Factorio 2.0.59+.  When
factorio.enable_lua_udp is set the instance binds a localhost UDP socket,
starts Factorio with --enable-lua-udp on factorio.lua_udp_port (random
if null, like the RCON port) and tells the clusterio module the host port
via clusterio_private.update_instance.

Data from Factorio is sent with clusterio_api.send_udp(channel, data) in
the same IPC format as send_json, so plugins receive it through the
existing ipc-<channel> events.  Packets not sent from the Lua UDP port
are ignored, as that is the only unauthenticated way into the IPC
handler.  Data to Factorio is sent with the new sendUdp method on
instances and instance plugins, and is dispatched in-game as
on_udp_packet_received events by polling helpers.recv_udp every tick
from the clusterio module.

Plugins requiring UDP declare the new LuaUdp feature flag, which like
SavePatching and ScriptCommands refuses to load the plugin on instances
without the option enabled.

Verified against a headless 2.1.17 server: send_udp and recv_udp are
silent no-ops when the option is off, so a stale port in a save that is
moved to an instance without UDP does no harm.  The integration test
matrix now starts the instance with UDP enabled on Factorio 2.0.59+ and
round trips a player event over it.

Closes #969

bbassieandClaude Opus 5.5 ad4595a257 Make the send buffer limit a config and start a new session on overflow
Add controller.max_send_buffer_size in MiB, default 64 and 0 for no
limit. Close with 1013 instead of 1008 on overflow: clients treat 1008
as fatal, so a host would shut down and the web UI would log out. With
1013 the client resumes, the controller answers with invalidate since
the session has ended, and the client registers a new session.

A subscriber could keep sending subscribe requests with new filters and
the controller would add every one of them to the subscriber's filter
set without bound, growing memory until it ran out.

Add controller.max_subscription_filters (default 10000) and reject
subscribe and replace requests that would leave a subscriber holding
more filters than that for one event.

Hornwitser 5df5af7ca8 Rename Ctl's usage of "control" to "ctl" (#1039)
Ctl ended up calling its main class for "Control" for historical
reasons, along with its config file and plugin entrypoint.

The plugin entrypoint was renamed to ctl in 808eda0513.  This
finishes that renaming by also renaming the main class, default config
file, config-control command, and main entrypoint.

The config-control command is renamed to config to be consistent with
the host and controller's config commands.

The term "control" is still kept in the config and message locations as
a common specifier for both ctl and web_ui.

89c51f0f74 Document missing config options (#995)
configuration.md was missing most options added over the last few years. Add the controller, host and instance options that weren't listed, mark the internal ones, note the validation rule under each field that has one, and fix entries that had gone stale: the tls defaults, the proxy_stream_timeout name, game port assignment from host.factorio_port_range, the three sync list modes, and the player_online_autosave_slots heading.

Plugin options live in the plugin READMEs, so add the missing ones for inventory_sync, player_auth and subspace_storage there. config-system.md gets the field definition properties it didn't list yet.

Hornwitser fb3fe09466 Remove tlsCa option
The migration from phin to fetch in #755 was hampred by the lack of an
option to set the CA when using fetch.  This meant places that used phin
to talk to the controller with the tlsCa option could not be migrated to
use fetch.

Remove the tlsCa option to unblock this dependency. The replacement for
this option is to set the NODE_EXTRA_CA_CERTS environment variable to a
path to the certificate file instead, which works with fetch.

Hornwitser 3592ff3269 Remove automatic creation of TLS certificate
The automatic creation of a self-signed certificate while nice presents
several problems.  To make connections not reject the self-signed
certificate the validation of TLS certificates are wholesale disabled,
decreasing the security even when properly set up and trusted
certificates are used.

To make the created self-signed certificate pass validation it is
necessary for it to list the host names it's valid for and to copy it to
each machine that intends to connect to the server.  These two steps
complicate automating the process in a reliable way and will likely lead
to confused users seeking to disable TLS certificate validation as the
easy way out to problems.

For these reasons, remove the automating creation of a broke self-signed
certificate, fix validation of certificates and document how to set up
TLS properly.  This makes HTTPS recommended when accessing over the
internet, but still something which must be explicitly configured.
