Use database temp dir for wallet db in integration tests instead of in-memory DB

[piotr-iohk]

Issue Number

Overview

• I have modified integration tests so they are using temp dir during test execution

Comments

Unfortunately tests failed for me locally with:

[cardano-wallet.worker:Error:4762] [2019-12-31 12:34:49.81 UTC] 7f084053: Recoverable error following the chain: SQLite3 returned ErrorMisuse while attempting to perform bind text.

malloc(): memory corruption

During the test I was also observing a lot of errors after deleting the wallet:

[cardano-wallet.worker:Error:4683] [2019-12-31 12:34:49.33 UTC] c0486500: Worker has exited unexpectedly: SQLite3 returned ErrorMisuse while attempting to perform close: bad parameter or other API misuse

These errors are interesting and look like some kind of concurrency issue. Are any tests running concurrently? This could be disabled with stack test --ta '--jobs 1' ...

• SQLite supports multiple processes accessing the same database file concurrently.
• SQLite also supports multiple threads within the same process accessing the same database file. This is because persistent-sqlite compiles with SQLITE_THREADSAFE=1 and therefore serializes the db statements.

Perhaps the .wal file gets deleted while SQLite expects it to exist?

Are any tests running concurrently?

There were some tests running in parallel. I have the parallel (temporarily to check the behavior) in 7e7c911.

After this the tests were running fine, until one of them failed and then all subsequent seemed to fail too:

 src/Test/Integration/Framework/DSL.hs:369:5: 
  1) API Specifications, STAKE_POOLS_JOIN_01x - Fee boundary values, STAKE_POOLS_JOIN_01x - I cannot join stake-pool with 0 balance

       expected: Status {statusCode = 204, statusMessage = "No Content"}
        but got: Status {statusCode = 500, statusMessage = "Internal Server Error"}

  To rerun use: --match "/API Specifications/STAKE_POOLS_JOIN_01x - Fee boundary values/STAKE_POOLS_JOIN_01x - I cannot join stake-pool with 0 balance/"

  src/Test/Integration/Framework/DSL.hs:1308:20: 
  2) API Specifications, STAKE_POOLS_QUIT_01x - Fee boundary values, STAKE_POOLS_QUIT_01x - I can quit if I have enough to cover fee
       uncaught exception: ErrorCall
       deleteAllWallets: Cannot return wallets: DecodeFailure "Something went wrong"
       CallStack (from HasCallStack):
         error, called at src/Test/Integration/Framework/DSL.hs:1308:20 in cardano-wallet-core-integration-2019.6.24-4tlWRZOKIL21Vt85fyPn5j:Test.Integration.Framework.DSL

Note. Running STAKE_POOLS_JOIN_01x alone works fine, so I don't think it is a matter of this particular test...

Running with stack test --ta '--jobs 1'... caused tests to stop again with the same error as initially:

[cardano-wallet.worker:Error:4762] [2019-12-31 12:34:49.81 UTC] 7f084053: Recoverable error following the chain: SQLite3 returned ErrorMisuse while attempting to perform bind text.

I have also reported #1242 to address the issue with error in log after deleting a wallet.

Closing until #703 is done.
