# 2023-02-25: MONITOR FIRMWARE UPDATES in 3 places especially...
#
# 1. apt changelog firmware-brcm80211
#    https://github.com/RPi-Distro/firmware-nonfree -> debian/config/brcm80211 (brcm, cypress)
#    https://archive.raspberrypi.org/debian/dists/bullseye/main/binary-arm64/Packages (1.1MB text file, look inside for summary of latest firmware-brcm80211)
#    https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/ -> firmware-brcm80211_* e.g.:
#    https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20190114-1+rpt11_all.deb from 2021-01-25
#    https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20210315-3+rpt4_all.deb from 2021-12-06
#    https://archive.raspberrypi.org/debian/pool/main/f/firmware-nonfree/firmware-brcm80211_20221012-1~bpo11+1+rpt1_all.deb from 2022-11-17
# 2. apt changelog linux-firmware-raspi

#- name: Back up 4 OS-provided WiFi firmware files (incl symlink contents) to /lib/firmware/cypress/*.orig
- name: Back up 4 OS-provided WiFi firmware files (replicate any symlinks) to /lib/firmware/cypress/*.orig -- /usr/bin/iiab-check-firmware will later do similar (e.g. as firmware install completes) -- moving 2-or-4 of these to <ORIGINAL FILENAME>.YYYY-MM-DD-HH:MM:SS ("doubly timestamping" to preserve BOTH last-modif & moving date)
  # copy:
  #   src: /lib/firmware/cypress/{{ item }}
  #   dest: /lib/firmware/cypress/{{ item }}.orig
  #   #local_follow: False    # FAILS TO PRESERVE LINKS (ansible/ansible#74777) e.g. /lib/firmware/cypress/cyfmac43455-sdio.bin -> /etc/alternatives/cyfmac43455-sdio.bin -> ...
  # 2023-05-01 CLARIF OF BELOW:
  # 1) Even if 'mv' fails, no matter it'll continue to 'cp' below
  # 2) 'cp -P' == 'cp --no-dereference' sufficient to replicate these symlinks and files ('cp -d' & 'cp -a' are incrementally stronger, and so probably can't hurt)
  shell: |
    mv /lib/firmware/cypress/{{ item }}.orig /lib/firmware/cypress/{{ item }}.orig.$(date +%F-%T)
    cp -a /lib/firmware/cypress/{{ item }} /lib/firmware/cypress/{{ item }}.orig

  #ignore_errors: yes    # 2023-02-25: Let's INTENTIONALLY surface any errors, e.g. if any future RasPiOS or Ubuntu-on-Rpi lack some of the above 4 files/links?
