Last active April 2, 2021 19:47
Sequel ConnectionWriteableValidator extension
# frozen-string-literal: true
# The connection_writeable_validator extension modifies a Database to validate
# that newly created connections are connected to writeable InnoDB servers.
#
# Based on advise given by Jeremy Evans
# https://groups.google.com/g/sequel-talk/c/JFuxfDuoAZ4/m/hTvgj71uBgAJ
#
# During an Aurora fail over, new connections may resolve to the old primary
# instance, which converts to a ready-only node.

# Checks if the current branch is already contained within the provided target ref.
#
# This solution varies from others with git diff or git log because commits themselves are ignored
# to allow for consistent results if the current branch is rebased/squashed/etc.
# Instead, the change-set as a whole is compared to the target by attempting a merge in a detached
# state and inspecting to see if any resulting merge commit was "empty".

Returns the value of a float rounded using the number of decimal points provided as precision.
/**
* Returns the value of a float rounded using the number of decimal points provided as precision.
*
* Fixes binary rounding issues eg. Math.round(1.005 * 100) / 100 === 1 that present
* problems for accounting and finance-related software.
*
* The normal technique for rounding with decimals is to multiply the number by the log10 of the
* precision, round then divide by the same log eg. for 2 decimal points `round(num * 100) / 100`.
* The binary rounding issue, however, causes this: 1.005 * 100 === 100.49999999999999.
