joshua-spacetime fc47257d85 Use SpacetimeDBGuard for SDK test suite (#5340)
# Description of Changes

Use an isolated server process per SDK test instead of a single process
for all of the tests. In addition to reducing the memory footprint of
each test run, this should also allow for more parallelism among the
individual tests.

Zeke Foppa 10a4779b13 wasm support for Rust SDK (#4183)
# Description of Changes

This PR adapts the Rust SDK test suite to work with the wasm version
added in https://github.com/clockworklabs/SpacetimeDB/pull/4089 (which
I've closed in favor of this PR).

Most of the changes revolve around wasm's different async semantics -
everything runs in one thread, so things that relied on background
threads didn't work directly. Several tests would lock up because
something in them blocked synchronously, which blocked any background
work from progressing.

We moved the test-clients contents into a `test_handlers.rs` so that it
could be called from both `main` (for native tests) and `lib` (for wasm
tests). To show what actually changed, use:
```bash
git diff --no-index -- <(git show origin/master:sdks/rust/tests/procedure-client/src/main.rs) sdks/rust/tests/procedure-client/src/test_handlers.rs
```
(or similar for other test-clients)

Phoebe Goldman 6882232108 Add a mode to the Rust SDK with additional logging to a file (#4566)
# Description of Changes

In the Rust client SDK, with this PR, doing
`.with_debug_to_file("path.txt")` on the connection builder will result
in the SDK logging additional verbose info to `path.txt`.

# API and ABI breaking changes

Adds a new user-facing-ish API to the Rust client SDK.

# Expected complexity level and risk

explicitly not for production use.

# Testing

- [x] Ran `chat-console-rs` locally with this enabled and got some debug

Shubham Mishra e2f8a60759 Case conversion (#4263)
# Description of Changes

Update the Default casing policy to `snake_case` for `RawModuleDefV10`.

Messy PR contains changes at different places, so that CI can pass:

Here are the main changes as follows:
- `bindings-macro` & `bindings` crate: `name` macro in Indexes for
canonical name and supply it to `RawModuleDefV10` via `ExplicitNames`.
- `bindings-typescript`: 
- Changes has been reviewed through this PR -
https://github.com/clockworklabs/SpacetimeDB/pull/4308.
   
- `binding-csharp`: a single line change to pass `sourceName` of index
instead of null.
- `codegen`:
  
- Changes has been merged from branch -
https://github.com/clockworklabs/SpacetimeDB/pull/4337.
  
- Except a fix in rust codegen to use canonical name in Query buillder
instead of accessor.
  
- `lib/db/raw_def`: Extends `RawDefModuleV10` structure to support case
conversion.
  
- `schema` crate:
- `validate/v9` - Nothing itself should change or changes in v9
validation logic but the file contains a `CoreValidator` which is shared
with `validate/v10`. No test have t be updated to `validate/v9` which
ensures we aren't regressing it.
- `validate/v10`: This is the main meat, look at the new tests added in
bottom to understand what it does.
     
   -  Rest of the files are either test updates or module bindings. 
     
    ## Testing:
1. Extensive unit tests have been added to verify generated `ModuleDef`
is correct.
2. I have done some e2e testing to verify rust codegen with rust and
typescript modules.
3. I would have like to do more testing for other codegens , I am
continue doing .

I have removed `sql.py` smoketest, as that seems to be already migated
in new framework and was headache to update.

## Expected complexity level and risk
4, It could have side-effect which aren't easily visible.

Phoebe Goldman 2c8f62e019 Make Rust test clients listen for reducer errors (#4359)
# Description of Changes

Prior to this commit, if a reducer call failed during a test in the Rust
SDK test suite, the client would hang, as it generally didn't register
callbacks when invoking reducers. This could mask some bugs, causing the
tests to fail with TIMEOUT rather than a useful message. For example, we
relied on consistency between all of the test modules, which was broken
by our not having updated the C++ bindings library to use the new
case-conversion scheme. This meant that the client was sending reducer
calls with incorrect reducer names to at least one database per test
run, which would result in a `Panic` status or an `Err(Err(_))` outcome.

With this commit, the SDK test clients are updated to inspect the exit
status of reducers they invoke, and (except for intentional reducer
failures) to panic the test client when encountering a reducer error or
panic.

# Testing

- [x] Automated tests passed locally.
- [x] Intentionally broke reducer calls via the 2.0 WS API, causing them
to skip the call and unconditionally respond with `Status::Panic`.
Observed "loud" failures in the test suite with non-`TIMEOUT` output
that looked more debuggable to me.

Piotr Sarnacki 4c962b9170 spacetime.json config implementation (#4199)
# Description of Changes

This PR implements support for the `spacetime.json` configuration file
that can be used to set up common `generate` and `publish` targets. An
example of `spacetime.json` could look like this:

```
{
  "dev_run": "pnpm dev",
  "generate": [
    { "out-dir": "./foobar", "module-path": "region-module", "language": "c-sharp" },
    { "out-dir": "./global", "module-path": "global-module", "language": "c-sharp" },
  ],
  "publish": {
    "database": "bitcraft",
    "module-path": "spacetimedb",
    "server": "local",
    "children": [
      { "database": "region-1", "module-path": "region-module", server: "local" },
      { "database": "region-2", "module-path": "region-module", server: "local" }
    ]
  }
}
```

With this config, running `spacetime generate` without any arguments
would generate bindings for two targets: `region-module` and
`global-module`. `spacetime publish` without any arguments would publish
three modules, starting from the parent: `bitcraft`, `region-1`, and
`region-2`. On top of that, the command `pnpm dev` would be executed
when using `spacetime dev`.

It is also possible to pass additional command line arguments when
calling the `publish` and `generate` commands, but there are certain
limitations. There is a special case when passing either a module path
to generate or a module name to publish. Doing that will filter out
entries in the config file that do not match. For example, running:

```
spacetime generate --project-path global-module
```

would only generate bindings for the second entry in the `generate`
list.

In a similar fashion, running:

```
spacetime publish region-1
```

would only publish the child database with the name `region-1`

Passing other existing arguments is also possible, but not all of the
arguments are available for multiple configs. For example, when running
`spacetime publish --server maincloud`, the publish command would be
applied to all of the modules listed in the config file, but the
`server` value from the command line arguments would take precedence.
Running with arguments like `--bin-path` would, however, would throw an
error as `--bin-path` makes sense only in a context of a specific
module, thus this wouldn't work: `spacetime publish --bin-path
spacetimedb/target/debug/bitcraft.wasm`. I will throw an error unless
there is only one entry to process, thus `spacetime publish --bin-path
spacetimedb/target/debug/bitcraft.wasm bitcraft` would work, as it
filters the publish targets to one entry.

# API and ABI breaking changes

None

# Expected complexity level and risk

The config file in itself is not overly complex, but when coupled with
the CLI it is somewhat tricky to get right. There are also some changes
that I had to make to how clap arguments are validated - because the
values can now come from both the config file and the clap config, we
can't use some of the built-in validations like `required`, or at least
I haven't found a clean way to do so.

# Testing

I've added some automated tests, but more tests and manual testing is
coming.

Tyler Cloutier 3f58b5951b Implement event tables (server, Rust/TS/C# codegen + client SDKs) (#4217)
## Summary

Implements event tables end-to-end: server datastore, module bindings
(Rust/TypeScript/C#), client codegen (Rust/TypeScript/C#), client SDKs
(Rust/TypeScript/C#), and integration tests.

Event tables are tables whose rows are ephemeral — they persist to the
commitlog and are delivered to V2 subscribers, but are NOT merged into
committed state. Rows are only visible within the transaction that
inserted them. This is the mechanism that replaces reducer event
callbacks in 2.0.

## What's included

### Server
- `is_event` flag on `RawTableDefV10`, `TableDef`, `TableSchema`
- Event table rows recorded in TxData but skipped during committed state
merge
- Commitlog replay treats event table inserts as no-ops
- Migration validation rejects changing `is_event` between module
versions
- `SELECT * FROM *` excludes event tables
- V1 WebSocket subscriptions to event tables rejected with upgrade
message
- V2 subscription path delivers event table rows correctly
- `CanBeLookupTable` trait — event tables cannot be lookup tables in
semijoins
- Runtime view validation rejects event tables

### Module bindings
- **Rust**: `#[spacetimedb::table(name = my_events, public, event)]`
- **TypeScript**: `table({ event: true }, ...)`
- **C#**: `[Table(Event = true)]`

### Client codegen (`crates/codegen/`)
- **Rust**: Generates `EventTable` impl (insert-only) for event tables,
`Table` impl for normal tables. `CanBeLookupTable` emitted for non-event
tables.
- **TypeScript**: Emits `event: true` in generated table schemas.
`ClientTableCore` type excludes `onDelete`/`onUpdate` for event tables
via conditional types.
- **C#**: Generates classes inheriting from `RemoteEventTableHandle`
(which hides `OnDelete`/`OnBeforeDelete`/`OnUpdate`) for event tables.

### Client SDKs
- **Rust**: `EventTable` trait with insert-only callbacks, client cache
bypass, `count()` returns 0, `iter()` returns empty
- **TypeScript**: Event table cache bypass in `table_cache.ts` — fires
`onInsert` callbacks but doesn't store rows. Type-level narrowing
excludes delete/update methods.
- **C#**: `RemoteEventTableHandle` base class hides delete/update
events. Parse/Apply/PostApply handle `EventTableRows` wire format, skip
cache storage, fire only `OnInsert`.

### Tests
- 9 datastore unit tests (insert/delete/update semantics, replay,
constraints, indexes, auto-inc, cross-tx reset)
- 3 Rust SDK integration tests (basic events, multiple events per
reducer, no persistence across transactions)
- Codegen snapshot tests (Rust, TypeScript, C#)
- Trybuild compile tests (event tables rejected as semijoin lookup
tables)

## Deferred
- `on_delete` codegen for event tables (server only sends inserts;
client synthesis deferred)
- Event tables in subscription joins / views (well-defined but
restricted for now)
- C++ SDK support
- RLS integration test

## API and ABI breaking changes

- `is_event: bool` added to `RawTableDefV10` (appended, defaults to
`false` — existing modules unaffected)
- `CanBeLookupTable` trait bound on semijoin methods in query builder
(all non-event tables implement it, so existing code compiles unchanged)
- `RemoteEventTableHandle` added to C# SDK (new base class for generated
event table handles)

## Expected complexity level and risk

3 — Changes touch the schema pipeline end-to-end and all three client
SDKs, but each individual change is straightforward. The core risk area
is the committed state merge skip in `committed_state.rs`. Client SDK
changes are additive (new code paths for event tables, existing paths
unchanged).

## Testing

- [x] `cargo clippy --workspace --tests --benches` passes
- [x] `cargo test -p spacetimedb-codegen` (snapshot tests)
- [x] `cargo test -p spacetimedb-datastore --features
spacetimedb-schema/test -- event_table` (9 unit tests)
- [x] `pnpm format` passes
- [x] Rust SDK integration tests pass (`event_table_tests` module)

Phoebe Goldman 1592dec8af Update Rust client SDK for V2 WebSocket format (#4257)
# Description of Changes

Update the Rust client SDK to use the new V2 WebSocket format, and
present the V2 user-facing API.

## Reducer events

### Remove on-reducer callbacks

It's no longer possible to observe reducers called by other clients by
registering callbacks with `ctx.reducers.on_{my_reducer}`. We no longer
code-generate those methods, or the associated
`ctx.reducers.remove_on_{my_reducer}`. Internal plumbing for storing and
invoking those callbacks is also removed.

### Add specific reducer invocation callbacks

In addition to the previous way to invoke reducers,
`ctx.reducers.{my_reducer}(args...)`, we add a method that registers a
callback to run after the reducer is finished. This method has the
suffix `_then`, as in `ctx.reducers.{my_reducer}_then(args...,
callback)`.

The callback will accept two arguments:
- `ctx: &ReducerEventContext`, the same context as was previously passed
to on-reducer callbacks.
- `status: Result<Result<(), String>, InternalError>`, denoting the
outcome of the reducer.
- `Ok(Ok(())` means the reducer committed. This corresponds to
`ReducerOutcome::Ok` or `ReducerOutcome::Okmpty` in the new WS format.
- `Ok(Err(message))` means the reducer returned an "expected" or "user"
error. This corresponds to `ReducerOutcome::Err` in the new WS format.
- `Err(internal_error)` means something went wrong with host execution.
This corresponds to `ReducerOutcome::InternalError` in the new WS
format.

Internally, the SDK stores the callbacks in its `ReducerCallbacks` map.
This is keyed on `request_id: u32`, a number that is generated for each
reducer call (from an `AtomicU32` that we increment each time), and
included in the `ClientMessage::CallReducer` request. The
`ServerMessage::ReducerResult` includes the same `request_id`, so the
SDK pops out of the `ReducerCallbacks` and invokes the appropriate
callback when processing that message.

These new callbacks are very similar to the existing procedure
callbacks.

### The `Event` exposed to row callbacks

Row callbacks caused by a reducer invoked by this client will see
`Event::Reducer`, the same as they would prior to this PR. These
callbacks will be the result of a `ServerMessage::ReducerResult` with
`ReducerOutcome::Ok`. In order to expose the reducer name and arguments
to this event, the client stores them in its `ReducerCallbacks` map,
alongside the callback for when the reducer is complete.

Row callbacks caused by any other reducer, or any non-reducer
transaction, are now indistinguishable to the client. These will see
`Event::Transaction`, which is renamed from the old
`Event::UnknownTransaction`.

### Less metadata in `ReducerEvent`

Some metadata is removed from `ReducerEvent`, as the V2 WebSocket format
no longer publishes it, even to the caller.

## `CallReducerFlags` are removed

All machinery for setting, storing and applying call reducer flags is
removed from the SDK, as the new WS format does not have any non-default
flags.

## Requesting rows in unsubscribe

When sending a `ClientMessage::Unsubscribe`, we always request that the
server include the matching rows in its response
`ServerMessage::UnsubscribeApplied`. This saves us having to update the
SDK to store query sets separately, at least for now. (We'll do that
later.)

## Handling rows

The new SDK does some additional parsing to wrangle rows in the new
WebSocket format into the same internal data structures as before,
rather than re-writing the client cache. (We'll do that later.)
Specifically, parsing of `DbUpdate` is changed so that:

- We parse raw `TransactionUpdate` into the generated `DbUpdate` type,
which requires an additional loop compared to the previous version, to
cope with the new WS format's dividing updates by query set. We define a
function `transaction_update_iter_table_updates` which encapsulates this
nested loop in an iterator.
- We have two new functions for parsing raw `QueryRows` into the
generated `DbUpdate` type, one for when they come from a
`SubscribeApplied`, and the other when they come from an
`UnsubscribeApplied`. `QueryRows` from `SubscribeApplied` translate to a
`DbUpdate` of all inserts, while one from `UnsubscribeApplied` will be
all deletes.

## Legacy subscriptions

"Legacy subscriptions" are removed. These were only used for
`subscribe_to_all_tables`, which as of now is stubbed. I will follow up
with a change to re-implement `subscribe_to_all_tables` by
code-generating a list of all known tables, and having it subscribe to
`select * from {table}` for every table in that list.

## `subscribe_to_all_tables` via a list

Previously, `subscribe_to_all_tables` worked by sending a legacy
subscription with the query `SELECT * FROM *`, which the host had
special handling to expand to subscribing to all tables. As legacy
subscriptions are no longer usable in V2 clients, this can't work.
Instead, we code-generate `SpacetimeModule::ALL_TABLE_NAMES`, a list of
all the known table names. `subscribe_to_all_tables` then maps across
this list to construct a list of queries in the form `SELECT * FROM
{table_name}`, and subscribes to all of those queries. This has the
upside that defining a new table in the module without regenerating
client bindings will no longer result in the client seeing rows of
tables it does not know about and cannot parse.

## Light mode removed

Light mode is no longer meaningful in the V2 WS format, so all code
related to it is removed.

## Internal changes

### Renamed WS messages

The SDK's internal code is updated to account for various renames:

- `QueryId` -> `QuerySetId`, `query_id` -> `query_set_id`.
- `SubscribeMulti` -> `Subscribe`, `UnsubscribeMulti` -> `Unsubscribe`.

## Incidental changes in this PR, not necessary for other client SDKs

### Don't filter out empty ranges in `RowSizeHint`

The Rust implementation of `RowSizeHint` in `BsatnRowList` got regressed
in the base branch to not work with zero-sized rows. This change fixes
that.

# API and ABI breaking changes

Boy howdy is it!

# Expected complexity level and risk

3? Changes ended up being less complicated than I feared, but we do have
some fiddly code here, and we have internal dependencies on the SDK.

# Testing

<!-- Describe any testing you've done, and any testing you'd like your
reviewers to do,
so that you're confident that all the changes work as expected! -->

- [x] Updated automated test suite.
  - Known failures:
- [ ] `subscribe_all_select_star`, which is currently broken because
it's trying to subscribe to rows from private tables. #4241 will fix
this.

Tyler Cloutier 184d4e9d3f Implement server-side support for the v2 websocket protocol (#4213)
# Description of Changes

This adds the v2 websocket protocol and adds support on the server side.
For context on many of the changes/decisions, you can look at the
discussion on https://github.com/clockworklabs/SpacetimeDB/pull/4023.

To restate some of the key changes:
- The reducer event information is no longer sent with transaction
updates (because we don't want to broadcast reducer call information
anymore).
- If a client calls a reducer, they are sent a `ReducerResult` which
includes the outcome of the reducer call and and related row updates for
queries that the client is subscribed to.
- We no longer dedupe queries that appear in multiple query sets for the
same client. This is because we are moving toward per-query storage.
- Related to that, Unsubscribe requests have an option to send the
related rows. We need this for now, since clients don't have per-query
storage implemented yet.
 - We don't have the json format in v2.

Notes for reviewers:
- This moves around the messages in
`crates/client-api-messages/src/websocket` (into `common`, `v1`, and
`v2`), and this renaming of existing messages adds a lot of noise to the
PR.
- In many places, I chose to duplicate a lot of code to have a v1
version and a v2 version. I went with this to make it easier to remove
the v1 version in the future (hopefully we can just fully delete most of
the v1 functions).
- `module_subscription_manager.rs` has probably has the biggest changes,
since we now track queries by query_set_id, and we get to remove some
complexity of v1's FormatSwitch.

<!-- Please describe your change, mention any related tickets, and so on
here. -->

# API and ABI breaking changes

The v1 protocol still works, though we won't send the reducer event info
for v10 modules.

# Expected complexity level and risk

4. This touches a lot of places.

# Testing

Unit testing is pretty minimal for the new code paths. I've done some
manual e2e testing with the typescript quickstart, and this has been
tested with a different branch implementing the v2 rust client.

Jason Larabie c59ee1ddc3 [2.0 Breaking] Add --include-private and default private tables to not generate (#4241)
# Description of Changes
Updated the codegen table/function iteration functions to take in a
parameter to check visibility in all locations for the supported
languages.
- Updated the util.rs functions for iterating tables/functions to check
for a CodegenVisibility enum (IncludePrivate, or OnlyPublic)
- Added a new CodegenOptions struct to pass around the CodegenVisibility
and future flags, defaulted visibility to OnlyPublic
- Updated the CLI to return a list of all private tables not included
(added a TODO to check the --include-private opt):
```bash
Optimising module with wasm-opt...
Build finished successfully.
Skipping private tables during codegen: secret_note, secret_order, secret_person.
Generate finished successfully.
```

# API and ABI breaking changes

Technically API breaking as the private tables will no longer be
available. (GitHub labels are not working at the moment)

# Expected complexity level and risk

1 - Simple change the testing took longer

# Testing

Turns out when you remove private tables you invalidate most of the
module_bindings across the system!

- [x] Rust test SDK for all languages
- [x] C# SDK tests
- [x] C# dotnet tests
- [x] Updated and checked snap files
- [x] Updated Blackholio (Unreal + Unity) module_bindings and tested

joshua-spacetime a78b056fcc Reorganize types generated for typescript clients (#4258)
NOTE: Cherry-picking
https://github.com/clockworklabs/SpacetimeDB/pull/4127 from the
`2.0-breaking-changes` branch.

## Original PR Description

This changes generated types in ts client bindings. We currently
generate a few different types of types: reducer args, procedure args,
rows, and user defined types. To avoid potential conflicts between these
types (for example, if a user defined a type called `FooRow`, and also
had a tabled named `foo`, we would end up with two types named
`FooRow`), this puts each set of types in a different file and
namespace. We also stopped exporting the `xxxRow` types, because there
is always another type generated for those. We now have a `types`
directory, which has an `index.ts` with user defined types, along with
`reducers.ts` and `procedures.ts` for the types generated for
reducer/procedure parameters.

```
import type * as Types from './module_bindings/types';

var currentMessages: Types.Message[] = [];
```

or

```
import { type Message } from './module_bindings/types';

var currentMessages: Message[] = [];
```

This has a couple other changes:
- For procedure and reducer types, this adds a suffix of `Args`, since
we may want types for the return values in the future.
- For all of the types, instead of exposing the schema object, we are
now giving the typescript type (e.g. `export type Message =
__Infer<typeof MessageRow>;`). I couldn't think of a reason for users to
want the schema object, so this should save users from needing to do all
of the `Infer` boilerplate.

This is a breaking change for v2.

2. This only changes typescript, and it should generally make thing
easier to use.

Mazdak Farrokhzad 65c8a8a9da Fixes #3240, perf of indexing many rows with same key (#3971)
# Description of Changes

Fixes https://github.com/clockworklabs/SpacetimeDB/issues/3240.

Non-unique indices are now backed by a type `SameKeyEntry` which holds
the `RowPointer`s for the same key.
When these `RowPointer`s exceed 4KiB (512 entries), the data structure
switches from using an array list to a hash set.

Mario Montoya 8fb0bcf922 Add UUID built-in convenience type to SpacetimeDB (#3538)
# Description of Changes

Closes
[#3290](https://github.com/clockworklabs/SpacetimeDB/issues/3290).

Adds a new "special" type to SATS, `UUID`, which is represented as the
product `{ __uuid__: u128 }`. Adds versions of this type to all of our
various languages' module bindings libraries and client SDKs, and
updates codegen to recognize it and output references to those named
library types. Adds methods for creating new UUIDs according to the V4
(all random) and V7 (timestamp, monotonic counter and random)
specifications.

Noa afe169ac4a Fix the issues with scheduling procedures (#3816)
# Description of Changes

This reapplies the patch from #3704, and fixes the issues that were
causing it to deadlock.

The reason it was deadlocking was that it allowed for the following
sequence of events:
* `SchedulerActor::handle_queued()` begins mutable tx
* `ModuleHost::disconnect_client()` submits call to `call_reducer(tx:
None)`
* scheduler submits call to `call_reducer(tx: Some)`
* `WasmModuleInstance::disconnect_client` now has to try to take tx
lock, but the scheduler's call_reducer already holds it and is behind it
in the queue

So, I moved most of the logic from `handle_queued` back to being
executed in the module worker thread, but kept the code in
`scheduler.rs` so that it can all be reasoned about locally.

Fixes #3645. Should I uncomment the implementation of
`ExportFunctionForScheduledTable for F: Procedure` now?

# Expected complexity level and risk

2 - there's a chance that this patch hasn't fully fixed the deadlock
issue from #3704, but I'm quite confident.

# Testing

- [x] Manually verified that deadlock no longer occurs - previously,
`while true; do python -m smoketests schedule_reducer -k
test_scheduled_table_subscription; done` would freeze up in only 2 or 3
iterations, but now it can run for 10 minutes without issues.

Phoebe Goldman 565e95bdf4 Add Rust client SDK bindings for calling procedures (#3532)
# Description of Changes

This commit adds support to the Rust client SDK for calling procedures.

Similar to reducers, each `DbContext` implementor has a `pub procedures:
RemoteProcedures` field, with methods provided by extension traits for
each procedure.

Unlike reducers, the provided methods are invoke and invoke-then.
Invoke-then takes a `FnOnce` callback to run
when the SDK is notified of the procedure's termination status, while
invoke ignores that notification.
No mechanism is provided for observing procedures invoked by other
clients.

Procedure callbacks are implemented by storing a map from `request_id`
to `ProcedureCallback`, with the callback closure internally knowing how
to deserialize the return value. It's mildly unfortunate to deserialize
within the callback instead of on the preprocess background task, but it
saves significant complexity.

This commit also adds a new sdk-test module, `sdk-test-procedures`, and
a new Rust test client, `procedure-client`.
Together, these are used in two tests of invoking and observing
procedures. I've left TODOs for other tests that we should write as we
implement additional procedure features.

I also had to fix a few minor bugs in the Rust codegen which were not
strictly related to procedures: we previously assumed that the sets of
reducers and of tables were non-empty, which led to wonky invalid
codegen on modules which did not define any reducers or which did not
define any tables.

I'm sneaking a change to the Nix flake into this PR as well - when
initially writing it I had included `cargoArtifacts` (the pre-built and
cached dependencies of our actual builds) in its `packages`, but that
was neither necessary or useful, and just made building the shell take a
long time after dependency changes.

# API and ABI breaking changes

Breaks the internal interface between the Rust client SDK and codegen,
so users will have to re-run `spacetime generate`.

# Expected complexity level and risk

2-ish? Pretty simple change to the Rust SDK overall.

# Testing

- [x] Added new automated integration tests exercising the new
functionality.

Phoebe Goldman 3f1de9e096 WASM host execution for procedures (#3498)
# Description of Changes

This commit builds support for executing procedures in WASM modules.
This includes an HTTP endpoint,
`/v1/database/:name_or_address/procedure/:name POST`, as well as an
extension to the WS protocol. These new APIs are not wired up to the CLI
or SDKs, but I have manually tested the HTTP endpoint via `curl`. The
new WS extensions are completely untested.

Several TODOs are scattered throughout the new code, most notably for
sensibly tracking procedure execution time in the metrics.

I also expect that we will want to remove the `procedure_sleep_until`
syscall and the `ProcedureContext::sleep_until` method prior to release.

# API and ABI breaking changes

Adds new APIs and ABIs.

# Expected complexity level and risk

3? 4? Unlikely to break existing stuff, 'cause it's mostly additive, but
adds plenty of potentially-fragile new stuff. Notably is the first time
we're doing anything actually `async`hronous on a database core Tokio
worker, and we don't yet have strong evidence of how that will affect
reducer execution.

# Testing

- [x] Manually published `modules/module-test` and executed procedures
with the following `curl` invocations:
- `curl -X POST -H "Content-Type:application/json" -d '[]'
http://localhost:3000/v1/database/module-test/procedure/sleep_one_second`
- `curl -X POST -H "Content-Type:application/json" -d '[1223]'
http://localhost:3000/v1/database/module-test/procedure/return_value`
- [ ] Need to write automated tests.

Jeffrey Dallatezza bf37b2947b Add bindings for csharp modules to use JWT claims (#3414)
# Description of Changes

This exposes JWT claims for csharp modules, similar to how they are
exposed to rust modules in
https://github.com/clockworklabs/SpacetimeDB/pull/3288.

This adds the new types `AuthCtx` and `JwtClaims`, and adds an `AuthCtx`
to the `ReducerContext`.

`AuthCtx` represents the credentials associated with the request, and
`JwtClaims` represents a jwt token.

One difference from the rust version is that I didn't create helpers to
build an `AuthCtx` from a jwt payload. The reason is that we would need
to be able to compute the identity from the payload claims, which
requires a blake3 hash implementation. The first two c# libraries I
found had issues at runtime
([Blake3](https://www.nuget.org/packages/Blake3) is wrapping a rust
implementation, and
[HashifyNet](https://github.com/Deskasoft/HashifyNET/tree/main/HashifyNet/Algorithms/Blake3)
seems to be broken by our trimming because it uses reflection heavily).
I can look into taking the implementation from `HashifyNet`, since it is
MIT licensed, but I don't think we need to block merging on that.

# API and ABI breaking changes

This adds the new types `AuthCtx` and `JwtClaims`, and adds an `AuthCtx`
to the `ReducerContext`.

This also adds a csharp wrapper for the get_jwt ABI function added in
https://github.com/clockworklabs/SpacetimeDB/pull/3288.

# Expected complexity level and risk

2.

# Testing

This has a very minimal unit test of JwtClaims.

I manually tested using this locally with the csharp quickstart, and I
was able to print jwt tokens inside the module.

Jeffrey Dallatezza dbc49b1fd6 Add AuthCtx to ReducerContext for rust (#3288)
# Description of Changes

This exposes client credentials in reducer calls for rust.

# API and ABI breaking changes

API Changes:

The main API change is the addition of `AuthCtx` and the `sender_auth`
in `ReducerContext`. This also adds JwtClaims, which has some helpers
for getting commonly used claims.

ABI Changes:

This adds one new functions `get_jwt`. This uses
`st_connection_credentials` to look up the credentials associated with a
connection id.

This adds ABI version 10.2.

# Expected complexity level and risk

2. This adds new ABI functions

# Testing

I've done some manual testing with modified versions of the quickstart.

Phoebe Goldman 351af50578 Support BytesSources other than the one for reducer args (#3294)
# Description of Changes

Each reducer gets its arguments through an `ArgSource`, a Unix-file-like
abstraction for streams of bytes. Prior to this commit, we had an ABI
designed as if it could support other args sources, but it actually
hardcoded the ID of the reducer args source, and errored elsewhere.

This commit extends the `BytesSource` infrastructure to support other
bytes sources. This will be useful for exposing JWT payloads and HTTP
responses. No other `BytesSource` uses are actually included in this
commit, only the infrastructure.

This commit also defines a new host call,
`bytes_source_remaining_length`. This is intended to allow callers to
pre-allocate a buffer correctly sized to read the entire `BytesSource`
all at once. The new host function is added to a new ABI minor version,
10.1, so that old SpacetimeDB hosts can detect and reject too-new
compiled modules. I have added uses of this new function to
`__call_reducer__` in both Rust and C#, even though it's not strictly
necessary,
and I haven't removed the loop which repeatedly calls
`bytes_source_read` and grows the buffer.

# API and ABI breaking changes

Adds a new ABI minor version, `spacetime_10.1`. This means that old
SpacetimeDB hosts will reject new compiled modules.

# Expected complexity level and risk

2-ish? WASM ABI code is always fiddly, but this is a pretty simple case.

# Testing

- [x] New behavior and new host function are both hit through existing
tests that instantiate modules and call reducers against them, so I
believe automated testing is sufficient.

Jeffrey Dallatezza 1d08167ebd Store client credentials in a new system table (#2983)
# Description of Changes

This adds a new system table to store the jwt payloads of connected
clients. I'm planning to use this system table to expose client claims
to modules in subsequent PRs.

The new table is called `st_connection_credentials`. It is a **private**
system table which stores a mapping from `connection_id` to
`jwt_payload`. Note that a jwt payload is a json representation of the
clients claims, not a fully signed token.

The times when we need to insert and delete these rows closely mirrors
that of the existing `st_client` table, with 1.5 exceptions:
1. We weren't previously inserting to `st_client` until after the
`OnConnect` reducer ran (even though it was in the same transaction). We
want `st_connection_credentials` to be populated before calling the
reducer, so that the reducer can use it get the credentials, so I made a
change to insert to `st_client` and `st_connection_credentials` before
calling the reducer.
2. This difference has not actualized, but when clients start sending
refresh tokens, we will probably need to update the credentials stored
in this table.

This also enforces uniqueness of connection ids. A duplicate connection
id will now make the on-connect reducer fail (since it will violate
uniqueness when trying to insert to `st_connection_credentials`).

# Expected complexity level and risk

2.5

Adding a system table is a bit risky. This is almost rollback safe, with
one annoying case that is worth calling out:

If a database is created with this system table, opening it with an
older version of spacetimedb will only work if there is a snapshot of
the database. If we try to load a table without a snapshot, replaying
will fail on the first row for that table. This is because we don't
write the table schema information to the commit log when creating a
database. In practice, this is unlikely to be an issue, because new
databases asynchronously trigger a snapshot immediately after creation.

Migrating existing databases will be fine. On startup this will detect
that there is a missing system table, and add it in a way that writes it
to the commit log. Since it is in the commit log, we can open the
database with an older version and still understand the data for that
table.

# Testing

There are unit tests that cover opening a database created with an older
version (which doesn't have this table).

I manually tested opening a migrated database with an older version of
spacetimedb.
