Merge: from parallel_validatemove
* Modifies Full Server Demo recording to grab more data + timestamps per packet
* Adds editor-only "DemoServer" server backend that we can use in editor to play back full server demos. Switch editor to ServerMode and put path in GameSetup object
* New server-side batch-update of players routine - disabled by default as it's not validated yet. Controlled by `server.UsePlayerUpdateJobs`
* Added GamePhysics batch versions of OverlapCapsule and OverlapSphere
* Couple unit tests to check Water's batch queries against non-batched versions
Tests: A lot of server demos recorded and played back in the editor doing core activities (looting, harvesting, interacting). Made sure standalone server and client builds locally.
Merge: from main
Tests: none, no conflicts
Merge: from main
Tests: none
Clean: ServerDemo - fix up names of entities that get reported via errors
Tests: played back procgen demo
Bugfix: ServerDemoPlayer - invert the error reporting logic for DestroyEntity
Previously, we considered it an error if we couldn't find an entity that demo stream tried to destroy. But, if the server behaves correctly, then it should be already destroyed - so now we report an error when we do find an entity.
Tests: played back the complex demo from procgen - errors still present, but harmless
Update: FullServerDemo - wrap transient entity snapshotting in try-catch
- Also correctly clean up NetWrite
I've checked a bunch of code related to saving, and I'm 100% certain there are landmines that I haven't spotted. This way I've neutered the danger of recording the demo, and I'll be fixing up those cases as we discover them in the wild.
Tests: recorded a demo on Craggy
Bugfix: FullServerDemo - use save for disk instead of network when snapshotting transient entities
- Also couple safety checks for BasePlayer.Save, since now I'm triggering a path that usually isn't triggered for a class of entities (NPCs)
Tests: while recording a server demo, on a procgen map in a local server did all basic activities (looting, harvesting, crafting and building) + drove a bike and attacked a ScientistNPC at outpost. Then was able to play back both demo chunks.
Tests: on local standalone server and procgen world, went to pier monument and descended to find aggressive NPCs - no more exceptions in server log
Update: ServerDemoPlayer - report errors if failing to find entities
Need to verify if my previous changes are working in more complex scenarios.
Tests: none, trivial change
Update: FullServerDemo - detect full network ID range used in demo
Replaces old invalid system of just reserving a constant chunk
Tests: played back all demos that I have - all valid.
Update: FullServerDemo - support client RPCs for transient entities
Implemented via an extra parse of demo stream, but should be okay since it's an editor-only process.
Tests: Played the same demo where I collected wood - previously it quietly failed, now player got attributed resources.
Update: FullServerDemo - try to handle transient(not in the savefile) Entities
- Record an entity snapshot once per demo chunk if sending specific messages - Positions, Flags, RPC(both server-sending and recieving)
- DemoTransientEntities are not sent if we've sent an entity snapshot via Entities message during active chunk
- Fixed not handling demo messages that can have 0 connections associated with it
- Fixed incorrectly aborting on "unknown" message type when types are related to demo-specific messages.
In theory this should allow us to avoid missing entities scenarios when playing back, which helps with determinism. But the server-recieving-RPC scenario needs more work - we record the transient snapshot after we recorded an RPC from the client, so I need to implement look-ahead in demo playback (or do what client demo playback does and index the demo).
Tests: on Craggy in editor recorded a full server demo where I'm looting a wood-collectible. During playback it spawns, but doesn't get removed
Buildfix: if-def out editor only variable
Tests: build standalone server locally
Update: adding missing comment about layerMask in batched CheckCapsule
Tests: none, trivial change
Bugfix: found another invalid scatter
Tests: none, will come next
Bugfix: Fixing incorrect scatter logic in batched GetIgnore
Really need to cover this path with tests
Tests: none, will come next
Clean: removing -Batch suffix from APIs
Doesn't really add any additional clarity, and makes the code a smidge shorter
Tests: editor compile
Merge: from main
Tests: none
Merge: from profiling_improvements
Further reducing overhead by recording 25% less data overall (based on 350p release server snapshot)
Tests: Took a snapshot on Craggy in Editor
Update: ServerProfiler - Filter out ~25% of profiling scope by further removing tiny/cheap methods
- Using binaries built from f27f0281
There are some controversial changes:
* Filter out Newtonsoft.Json - we can't modify it's internals anyway
* Filter out setters (set_*) - overwhelming majority are cheap, but hides expensives ones. But we'll see the nested calls if there are any.
* Filter out IPooled callbacks - half of them are not implemented (usually LeavePool), and most fo them are cheap
There are bunch more, but not worth bringing up details.
Tests: on Craggy in editor
Merge: from main
Tests: none
Update: WaterLevel - rewrite WaterSystem GetIgnore serial chunk in batch form
This eliminates the other "jobify/batch" todo. Think I'll do a bit of cleanup, add more tests and get ready to merge to staging for stewing.
Tests: ran unit tests. Ran araound on craggy and checked a couple results of water checks.
Update: WaterCollision - add batch version for GetIgnore that does an overlap capsule test
Needed to get replace last serial chunk in batched WaterLevel.GetWaterInfos
Tests: none, compiled in editor
Update: GamePhisycs - added OverlapCapsule and CheckCapsure that use Unity jobs
Turns out I'll need it to support WaterCollision.GetIgnore(start, end...)
Tests: none, just compile
Bugfix: When spreading WaterInfo results, prevent trying to do a sawp between same indices
- This leads to invalidating WaterInfo, which returns invalid info
I need to extend tests to do checks with Entities, as this case/branch isn't covered currently
Tests: enabled parallel player updates and logged cached water checks - now it returns valid water where expected.
Bugfix: replace Temp allocators with TempJob allocators for physics jobs
- Added misisng resource cleanup
This partially fixes test failures.
Tests: ran the WaterLevel test checks
Update: WaterLevel.GetWaterInfos - replaced a serial GetWaterInfoFromVolumes call with a batched one
- should save us time by parallelizing physics checks, if they do get used
This removes one of 2 "batch" TODOs in the method.
Tests: ran unit tests, some are failing - will fix next.
Update: added batched WaterLevel.GetWaterInfoFromVolumes
- there's a number of inefficiencies - left TODOs to address later
Continuing to propagate batching support upwards, only got 1 level left to swap out a serial query with batched.
Tests: none, editor compile
Update: Added batched version of Vis.Components
Still building up to engage it as part of main parallel logic. Also still need to cover with tests.
Tests: compiles in editor
Clean: removing hanging meta files that I've commited earlier
Tests: open editor
Merge: from main
Tests: none
Merge: from hackweek_serverprofiler_memory
- Records allocations from all threads
- Displays allocations on separate thread tracks + a graph of total allocations per thread
- Allocations now have last/current method, allocated type and size in the mark's "arguments" - see "current selection" in perfetto
- Allocations now also duplicate in the executing thread to make it easier to spot where exactly in the method it was allocated.
- Graphs of working set and virtual set memory for the entire process
Tests: multiple snapshots in editor on Craggy, single in standalone debug linux server via WSL on 3k procgen map, single in standalone release windows server on 3k procgen map with a harmony mod
Clean: removing unnecessary using
Tests: compiled in editor
Clean: deleting empty folder
Left-over from the old merge that I didn't clean up properly
Tests: none
Update: ServerProfiler - switching to release libs (10b88e05)
Tests: tested stanadlone linux server in debug on a 3k procgen map, windows standalone server in release on a 3k procgen map and a harmony mod
Merge: from main
Tests: none
Clean: remove a couple unnecessary TODOs
Tests: none, trivial change
Clean: ServerProfiler - less IntPtr, more Native.MonoMethod
Think I didn't have enough sleep when I was writing it at first.
Tests: exported snapshot in editor on Craggy
Update: ServerProfiler - emit the current/last managed method when recording an allocation
- using debug binaries (10b88e5)
Should reduce/eliminate the need to manually hunt for the allocation in the methods view.
Tests: snaspshot in editor on Craggy
Update: ServerProfiler - emit a graph of per-thread total allocation size
- Main thread reset the counter every frame, worker threads over their entire lifetime.
This makes it easier to see at a glance how much we allocate per frame/thread.
Tests: exported snapshot in editor on Craggy
Update: ServerProfiler - update binary exporter & viewer to handle new Allocs format
- Made ProfileBinViewer's search work with alloc's names
Tests: made a debug export of Craggy in editor, then opened it in the ProfileBinViewer
Clean: ServerProfiler - remove not supported thread sorting keys
Tests: none, trivial change
Update: ServerProfiler - remove the class name and duplicate size into args of a mark
- They are part of the "arguments" view when you click on the allocation mark
- Also assigned all allocations the "A" category so that they can be easily filtered out via queries
Turns out cname (controlling colors) is also unsupported via legacy json import (see issue https://github.com/google/perfetto/issues/208 and linked ones), so if we modify the name, we lose the uniform yellow color for allocations that makes it easier to spot. This also allows to run queries on top of these args more easily.
Tests: exported snasphot from Craggy in editor
Update: ServerProfiler - track and emit allocation class and array size
- using debug binaries (9f4a07f8)
Will need to update binary export and fix the bin viewer tool
Tests: snapshot on craggy in editor
Bugfix: ServerProfiler - properly name worker thread's allocation track
- Another one of the "did it right first time, simplified, now it's borked" cases
Tests: snapshot in editor Craggy
Update: ProfilerExporter.JSON - emit virtual memory graph
Tests: exported on craggy
Optim: ServerProfiler - properly avoid false-sharing when recording memory state when taking a snapshot
- using debug binaries (b445081f)
Should be a smidge faster faster in multithread allocation-busy scenarios.
Tests: took a snapshot on craggy
