name: Arduino CI Build (2 of 4) Release Arduino wolfSSL for Local Examples

# TODO - implement this once future wolfSSL is released
#
#      Known to fail on current 5.8.2 wolfSSL Arduino Release
#
# See arduino.yml - Arduino CI Build (3 of 4) Latest wolfSSL for Local Examples

#
# Test local Arduino examples with published Arduino wolfssl
#
# These 4 workflows across 3 repos are interdependent for the current $REPO_OWNER:
#
# Arduino CI Build 1: https://github.com/$REPO_OWNER/wolfssl               #  /.github/workflows/arduino.yml
#   - Builds Arduino library from local clone of wolfssl master branch
#   - Fetches examples from https://github.com/$REPO_OWNER/wolfssl-examples
#
# THIS Arduino CI Build 2: https://github.com/$REPO_OWNER/wolfssl-examples #  /.github/workflows/arduino-release.yml
#    - Tests examples based on latest published release of Arduino library, NOT latest on wolfssl github.
#    - Should be identical to Arduino CI Build 3 in every way but wolfssl install.
#    - Copies only compile script from wolfssl-examples
#    - Builds local examples
#    - No other repos used
#
# Arduino CI Build 3: https://github.com/$REPO_OWNER/wolfssl-examples      #  /.github/workflows/arduino.yml
#   - Fetches current wolfSSL from https://github.com/$REPO_OWNER/wolfssl
#   - Creates an updated Arduino library
#   - Compiles local examples
#   - Contains the source of `compile-all-examples.sh` and respective board-list.txt
#
# Arduino CI Build 4: https://github.com/$REPO_OWNER/Arduino-wolfssl       #  /.github/workflows/arduino.yml
#    - Assembles and installs an updated Arduino wolfssl library from LOCAL wolfssl master source
#    - Copies only compile script copied from wolfssl-examples
#    - Builds local examples
#    - No other repos used
#
#
#                                   ** NOTE TO MAINTAINERS **
#
#           Consider using winmerge or similar tool to keep the 4 arduino[-release].yml files in relative sync.
#           Although there are some specific differences, most of the contents are otherwise identical.
#
# See https://github.com/wolfSSL/Arduino-wolfSSL
#
# To test locally:
# cd [your WOLFSSL_ROOT], e.g. cd /mnt/c/workspace/wolfssl-$USER
# [optional checkout]     e.g. git checkout tags/v5.8.4-stable
# pushd ./IDE/ARDUINO
# export ARDUINO_ROOT="$HOME/Arduino/libraries"
# ./wolfssl-arduino.sh INSTALL
# cd [your WOLFSSL_EXAMPLES_ROOT] e.g. /mnt/c/workspace/wolfssl-examples-$USER
