ConnectionPool crash on keepalive with non-empty request queue #472

lovetodream · 2024-05-07T17:55:14Z

Describe the issue

The connection pool crashes when a lot of requests occur in a burst

Vapor version

n/a

Operating system and version

macOS 14.4.1

Swift version

Swift Package Manager - Swift 5.10.0-dev

Steps to reproduce

Run the following script:

let config = PostgresClient.Configuration(...)
var logger = Logger(label: "connection-pool-crash")
logger.logLevel = .debug

let client = PostgresClient(
    configuration: config,
    backgroundLogger: logger
)
let task = Task {
    await client.run()
}

func runOnce() async throws {
    let logger = logger
    try await withThrowingDiscardingTaskGroup { group in
        for _ in 0..<20 {
            group.addTask {
                let hello = try await client.withConnection { db in
                    try await db.query("SELECT 'hello'", logger: logger)
                }.collect().first?.decode(String.self)
                print(hello)

                // wait for the connection pool to do ping pong and close
                try await Task.sleep(for: .seconds(idleTimeout + 1))
            }
        }
    }
}

for i in 0..<50 {
    try await runOnce()
    print("Burst done: \(i + 1)/50")
}

task.cancel()

Outcome

A crash happens (typically on the start of the second burst, after running the script for approx. 1.5 min), the crash occurs in PoolStateMachine.connectionKeepAliceTimerTriggered(_:) due to a non-empty request queue. My assumption is, that there's a race condition when the timer triggers the ping and the next batch of requests is "inserted" into the pool.

Thanks for the report! A couple of questions:

You listed your Swift version as 5.10-dev; is this from an Xcode beta, or are you using a nightly toolchain? If the latter, does the crash still occur with the release version of 5.10? Also, do you know if this crash also occurs on Linux?
Can you provide the full backtrace of the crash? You can retrieve the backtrace from Xcode's debugger console (the (lldb) prompt) with the bt all command, or in a commandline build you can set SWIFT_BACKTRACE='enable=yes,threads=all,images=all' in your environment to get a backtrace from the Swift runtime.

To q1, I do use Xcode 13.3, odd that it says 5.10-dev.
To q2:

I did actually chat with Fabian a moment ago on Discord and we agreed that I'll create a test case for the crash and continue on from there with his guidance if needed.

I am running into this too. Is there a purpose to the precondition precondition(self.requestQueue.isEmpty)? If it is safe for the keepAliveTimer to fire when there are outstanding requests why not just allow it? Crashing seems pretty harsh!

I am running into this crash when running in Xcode 16.0 (the non-beta released version).
