Infinite recursion when KNAPSACK_PRO_LOG_LEVEL is set to debug

[dmytro-workday]

Hi,

We have set KNAPSACK_PRO_LOG_LEVEL=debug and KNAPSACK_PRO_LOG_DIR=log, which leads to the following backtrace:

Seems like the issue is related to the following warnings, throws when the logging directory is not enabled:

You have set the environment variable KNAPSACK_PRO_CI_NODE_TOTAL to 36 which could be automatically determined from the CI environment as 9.
You have set the environment variable KNAPSACK_PRO_CI_NODE_INDEX to 1 which could be automatically determined from the CI environment as 0.

The configuration we used is similar to the FAQ answer here:

@dmytro-workday Could you work around the issue while we look into it? Or is this preventing you from using Knapsack Pro?

[dmytro-workday]

Yes. We have removed the _LOG_ variables for now and assigning the logger ourselves instead:

logger = Logger.new("log/knapsack_pro_node_#{KnapsackPro::Config::Env.ci_node_index}.log")
logger.level = ::Logger::DEBUG
KnapsackPro.logger = logger
