EXC_BAD_ACCESS when calling create_to_address (former send_to_address) #181

Open pacu opened 4 years ago

pacu commented 4 years ago

ONLY ON DEBUG MODE

reproduced on: note-spending-v5 and note-spending-v6

Context:

when calling create_to_address from unit tests, calls are made from the main thread and return successfully with the expected result (a transaction Id or an error message, like insufficient balance, etc)

 func testSendToAddress() {

        let tx = try! ZcashRustBackend.createToAddress(dbData: dataDbHandle.readWriteDb, account: 0, extsk: spendingKey, to: recipientAddress, value: Int64(zpend), memo: nil, spendParams: URL(string: __spendParamsURL().path)!, outputParams: URL(string: __outputParamsURL().path)!)
        XCTAssert(tx > 0)
        XCTAssertNil(ZcashRustBackend.lastError())
    }

On integration tests or the iOS demo app, the create_to_address is called from a 'background' thread which does not block the main thread (which handles the UI).

Example

 func testSpendGlobalQueue() {
        var txId: Int64 = -1
        let expectation = XCTestExpectation(description: self.description)
        DispatchQueue.global().async {
            txId = self.rustBackend.createToAddress(dbData: self.dataDbHandle.readWriteDb,
                                                account: 0,
                                                extsk: self.spendingKey,
                                                to: self.recipientAddress,
                                                value: Int64(self.zpend),
                                                memo: nil,
                                                spendParams:  try! __spendParamsURL(),
                                                outputParams: try! __outputParamsURL())
            expectation.fulfill()
        }
        wait(for: [expectation], timeout: 240)
        XCTAssertTrue(txId >= 0)
    }

The test above generates an EXC_BAD_ACCESS exception. Which usually means a segmentation fault / memory access problem of some sort.

I'll paste the details of the call stack and point out the failing line of each step as I got them from the debugger. the whole call stack is rather long and is in the last section of this issue.

Reposing from slack:

I dove into the Futures code a little bit and really didn't understand any of it, but I noticed there's some thread-dependent code in that call stack: https://github.com/rust-lang/futures-rs/blob/0.1.29/src/task_impl/std/mod.rs#L483 (it's defined in a thread_local! above). If you look at the stack trace it repeats at the end, so my guess was it's recursively polling on something that never gets satisfied and then runs out of stack space. That's as far as I got and I definitely don't understand it so could be a red herring.

@pacu is there more information about the exception, like register values / assembly instruction that triggered it?

pacu commented 4 years ago

I'll gather those and post them here or ping you
