memory leak with v6

See original GitHub issue

Expected behaviour:

Since upgrading from V5 to V6 my apps are slowly leaking memory.

It’s seems much worse when running in development mode with web pack but still does it when built.

Have yet to put them in their docker containers - will report back when i do…

They basically just create a connection and keep using it on a timer to send queries.

Actual behaviour:

They shouldn’t Leak

Configuration:

{
      "server": "127.0.0.1",
      "database": "History####",
      "user": "time",
      "password": "letmein",
      "connectionTimeout": 300000,
      "requestTimeout": 0
    }

Software versions

NodeJS: 11.14.0
node-mssql: 6.0.1
SQL Server: 2012

Ok I have found my issue…

I should have set mssql to use bluebird i’d assumed global.promise = Bluebird line would do that…

import Bluebird from 'bluebird'
import mssql from 'mssql'
import server from './server'

// no memory leaks with bluebird!
global.Promise = Bluebird
mssql.Promise = Bluebird
