* Gets the logger instance. There is only 1 per process, in accordance with how logging
|
|
* works within the CRT. However, there is 1 context per invocation of the module init
|
|
* function. In node versions < 12, this is always 1. In 12 and above, there can be worker
|
|
* threads which initialize all modules into their memory space on creation.
|
|
* Calls across env threads will not succeed, so for logging calls from within the node worker
|
|
* threads, they must use logging callbacks bound to their env/thread.
|
|
* Event loop threads, on the other hand, queue their logging against the main thread.
|
|
* This is not ideal, but node closes and re-opens stderr and stdout the first time
|
|
* console.log is called, so our logging gets broken. Can't beat 'em, have to join 'em.
