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.

Adds the last three checks from #342 to test_plugin: an InstanceEcho
request handled on a running instance, a Lua module with a remote
interface that the request calls over RCON, and log tagging checks for
the plugin field and host/instance ids on the controller, host and
instance log lines.
test_plugin now has a module, so the create_scenario and patch unit
tests that relied on it having none use global_chat instead.

Replace ESLint, typescript-eslint, eslint-plugin-node and the flat
config helpers with vite-plus, which runs Oxlint for vp lint. The rules
are carried over from eslint.config.mjs by @oxlint/migrate into the lint
section of the root vite.config.ts. The formatting rules ESLint
deprecated run as @stylistic rules through Oxlint's JS plugin support,
and disable comments naming them are updated to the @stylistic names.
@stylistic understands TypeScript syntax that the core rules skipped,
so the autofix adds missing semicolons and spaces in type literals and
aliases. Leading | and & in multiline types stay where they were.
Oxlint's node/no-sync also reports identifiers ending in Sync that are
not calls. The test helper techSync is renamed and the two other names
are ignored.

Error responses now carry the registered name of the thrown error's
class, and the requester rejects with an instance of that class instead
of a generic RequestError. Error classes are registered like message
classes, and plugins list their own in `errors`.
RequestError is replaced by a hierarchy following the HTTP status codes:
ClientError (ValidationError, ForbiddenError, NotFoundError,
TimeoutError, ConflictError) and ServerError (InternalServerError).
PermissionError is PermissionDeniedError and the config errors
InvalidValue, InvalidField and InvalidAccess gain an Error suffix.
Link logs only errors whose class is not registered. These arrive on the
other side as InternalServerError with the original message and stack,
so an error forwarded through the controller is logged once, where it
was thrown.

FactorioServer.fromOptions finds the Factorio install and generates the
RCON password before constructing, so _version and _dataDir are never
null and setTargetVersion and init are gone. checkForUpdates is now a
module function called before fromOptions.
Instance.fromConfig resolves the version, downloads Factorio if needed
and builds the server, then constructs the instance with it. It runs
before the instance is connected, so the starting and stopped statuses
and the version requests go through the host link. FactorioVersionsRequest
and LatestReleasesRequest now accept host as a source, and the host
tracks starting instances so a second start during a download is
rejected. Plugin loading stays a separate loadPlugins step after the
instance is connected.

Instance dir and save names are tried without a retry cap, as on master
and in downloadFile, so an 11th instance named "New Instance" still gets
a folder.
Moves fall back to an exclusive copy when hard links are unavailable
(EXDEV, EPERM, ENOTSUP), and remove the new target if the source can't
be unlinked, so a failed move leaves no duplicate.
Local transfers keep appending .zip to the target name, as
findUnusedName did.
The copy auto-rename test now checks that the existing target save is
left untouched.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The name it returns may already be taken by a concurrently running process
by the time the caller uses it. Callers now try the name and retry with a
-2, -3, ... suffix on EEXIST instead.
Save transfers previously renamed with fs.rename, which silently overwrites
a save that appears at the target, and copied without COPYFILE_EXCL. Moves
now use link + unlink like save rename does, and copies pass COPYFILE_EXCL,
so both fail with EEXIST rather than overwrite.
Supersedes #880.

Factorio 2.1.18 removed PollutionSettings::max_pollution_to_restore_trees,
but readPollution still read it for every version, so every map setting
after it was read 9 bytes late: enemy_attack_pollution_consumption_modifier
came out as garbage, the enemy_evolution factors shifted by one field and
enemy_expansion.enabled and both expansion distances came out null.
Read the field only for strings older than 2.1.18. Add modified_v2_1_17
and modified_v2_1_18 fixtures generated with headless 2.1.17 and 2.1.18
from the modified 2.1 settings (base game only), unit tests asserting
their full decoded output, and use the 2.1.18 string for the
load-scenario integration test on 2.1.18 and later.

* Wait for player list replication in integration tests
* Select available RCON ports before starting Factorio
* Document zero as automatic RCON port allocation
* Address review wording and test organization
* Restrict port collision hardening to integration fixtures
* Replace jszip with yauzl and yazl
jszip loads a whole archive into memory to read it and buffers the
output when writing. Saves and mods can be several hundred megabytes,
so read zips with yauzl, which only reads the central directory and
streams entries on demand, and write them with yazl, which streams the
output.
lib gains a ZipArchive wrapper around yauzl with the lookup helpers the
callers need, findRoot() now takes it instead of a JSZip. Saves are
patched by streaming every kept entry into a new zip, mod info.json is
read straight from the file, exports are streamed to the controller and
Factorio zip downloads go through a temp file instead of a buffer.
Patching now inflates and deflates each entry again where jszip reused
the compressed data, on a 336 MB synthetic save that is 7 s instead of
0.7 s, with peak memory going from 416 MB to 151 MB.
Closes#1002

* Copy save entries without recompressing them
yazl inflates and deflates every entry it is given, so patching a save
took ten times longer than with jszip, which reused the compressed
data. Add a ZipWriter to lib that streams entries out as they are
added and copies entries from a ZipArchive byte for byte, with ZIP64
structures when sizes or offsets need them, and use it in patch().
On a 336 MB synthetic save patching now takes 0.4 s at 143 MB peak RSS
against 0.75 s at 417 MB with jszip. Factorio loads the result.

* Handle save write errors before the patch loop awaits them
A write error on the temporary save, such as a full disk, rejected the
pipeline promise while addEntry() or addBuffer() was still pending. Nothing
was listening yet, so the host's unhandledRejection handler exited the
process instead of failing the instance start.

* Keep the export zip cache local to each export
The cache was module level, so when two instances on one host exported at

* Start writing zips before adding files from disk
yazl reads files passed to addFile() as soon as they are added. An
unreadable file emitted an error while the directory traversal was still
running, before the output pipeline existed, and the process exited on the
uncaught error. build_mod and zipDirectory now start the pipeline first and
reject instead. build_mod also removes the partial zip on failure.

send_udp and get_host_udp_port indexed script data that is only created
on the first tick after patching, so calling them from on_init stopped
the server. They now return nothing until then.
Received packets were only polled once the host port was known, which
needs script commands. Poll whenever recv_udp exists instead, it does
nothing when the server runs without --enable-lua-udp.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Review feedback from Cooldude2606: UDP is most useful for arbitrary
blobs, so send_udp now takes any string and the packet is just
"channel?payload". Plugins get it as a udp-<channel> event with the
payload as a Buffer, or through handleUdp which logs handler errors
like handle does for ipc events.
The host socket is now opened when the RCON client is started and
closed where the RCON client is ended, matching how the RCON client is
handled, instead of being bound in start() and closed by _resetState.
The integration round trip moved to the FactorioServer tests, where it
sends a packet each way through a real server without the module.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Codecov flagged the sendUdp methods on Instance and BaseInstancePlugin,
the bind, socket error, malformed packet and send failure paths in
FactorioServer, and the --enable-lua-udp branch of startScenario. Add
unit tests for each and start the integration scenario test with UDP
enabled on Factorio 2.0.59+.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
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.

The plugin syncs more than inventories now (settings, appearance, recipe
notifications), so name it for what it does. The package becomes
@clusterio/plugin-player_sync and every inventory_sync identifier follows.
A migration entrypoint renames the inventory_sync config fields, including
load_plugin, and the inventory view permission. The plugin moves
inventories.json in the database directory to player_sync.json and
storage.inventory_sync in saves to storage.player_sync itself, and closes
dialogs left open under the old GUI names on startup.

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.

These are used outside of the integration tests, but including the
integration index file causes the very slow setup of the contorller
and host. Avoid the integration setup costs when running commands
such as `pnpm mocha test/lib` by moving these utility functions to
the common test functions.
Without a transport Winston will print annoying "Attempt to write logs
with no transports" warnings all over the place. Setup a transport in
tests that cause logging to suppress this.
The behaviour of creating the config file if it's missing while
convenient causes confusion and problems when the tools are run
in the wrong folder. They end up creating a shadow installation
and misdirect the user with nonsensical error messages, instead
pointing to the real problem which is that the tool can't find
the configuration needed to actually run.
Require a config file to be present at startup and refuse to run if this
file is missing. To support the odd use-case of creating the config
when missing a --create-config flag is added. To conveniently generate
a config file to edit out from the "config create" command is added.
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.
Drop the special case that deferred terminating the connection issuing
the delete, so deleting yourself behaves the same as revoke-token and
every session of the deleted user is closed before the handler returns.
Set tokenValidAfter to the current time in createUser instead of 0.
Deleting a user and recreating it under the same name left tokens issued
before the deletion valid, as the check is iat < tokenValidAfter. Doing
it in createUser covers every path that makes a user. A token signed in
the same second as creation is still accepted, so create-admin and the
other production paths sign after the user exists and are unaffected.
The integration harness signed the control token at import time, before
bootstrap create-admin created the user. Sign it in the root before hook
instead and reuse it in link.js.

Resolves the ESM conflicts in patch.ts, Instance.ts and host.ts. The
module gathering in Instance now goes through patch.loadModules with
the instance's loadedPlugins, and imports use explicit extensions.
Review changes: the existing-output check only treats ENOENT as
"does not exist" and rethrows anything else, a --zip option keeps the
output as a zip file for transfer (extracting stays the default), the
--scenario option describes that it takes a path and what the default
is, and the docs note that IPC is not available outside Clusterio.

Migrate the usage of CommonJS specific code and imports to ESM. Roughly
summarised this:
- Changes all require() calls to import statement or expressions.
- Changes usage of module.exports to export statements.
- Replaces require.resolve with import.meta.resolve.
- Replaces conditional imports with conditional subpath imports.
- Replaces module === require.main with import.meta.main.
- Adds the full filename with extention to all relative imports.
- Changes all usage of __dirname and __filename to their import.meta
equivalents.
- Sets "type": "module" in package.json files.
- Removes usage of "use strict".
- Adds .ts an an alias of .js for the webpack build.
Due to differences in how require and import resolves files the plugin
entrypoints will have to include the filename and extension after this
migration in order to work.
Adds tests for handleCreateScenarioCommand using a fake Factorio
install with the test scenario as freeplay, for loadModules skipping
plugins without a module and rejecting a name clash with a bundled
module, and an integration test running clusteriohost create-scenario.

The create instance modal can now copy the active save of the instance
whose config is copied, optionally saving the running game first, and
start the new instance once the copy is done. The new instance is
assigned to the host of the source so the save can be transferred.
Saving a running game is a new InstanceSaveGameRequest handled by the
host through /server-save, which waits for the save to finish. It is
also exposed as clusterioctl instance save-game.

Nothing covered whether plugins are loaded at all, or whether the messages
they declare are routed. The integration tests only loaded the first party
plugins, so what coverage existed came incidentally from testing those.
Add a plugin under test/file which exists purely to be loaded by the tests.
It is plain JavaScript rather than TypeScript so that it needs no build
step, which the plugin loader is happy with as it requires the entry point
and reads the version from package.json like any other plugin.
Covered so far: the plugin loads on the controller and on the host, its
title and version are reported, the command it adds is available in
clusterioctl, a request from control reaches the controller, a request from
control reaches a host, and an event sent with broadcastEventToHosts
arrives at the hosts.
Left for a follow up, as all three need a running instance: a request to an
instance, a Lua module reached over rcon, and log statements being tagged
with the plugin and host or instance id.
Part of #342, and a step towards #721 as core no longer needs a first party
plugin to have the plugin system under test.

An event broadcast from an instance to all hosts only reached the host
running that instance. The host side of an instance connection has the
host's own address as its source, so a broadcast aimed at hosts counts as
addressed to it, and a link that a message is addressed to handles it and
stops. The event was delivered locally and never routed onwards.
A broadcast is addressed to every link of the type it targets, so arriving
at one of them does not mean it has arrived everywhere. Keep routing such a
message after handling it locally. Only links that route are affected, as
instances and controls have no router and would otherwise throw on every
broadcast they receive.
The only links whose source type matches a broadcast target and which route
are the host and its instance connections, both matching a broadcast to
hosts, so add the missing case for that to the host router. It forwards to
the controller, which already passes broadcasts on to every other host, and
stops when the message came from the controller to begin with.
Drop the exclusion this bug had in the routing test matrix, which now
covers it along with the plugin filtering variants.
