• One post per block/exclusion? Could ease not to loose exclusions around 9AM/PM.
• The exclusion through WebSocket event would be nice on GVA:
  • Already possible listening on /ws/blocks.
  • exclusions won’t be loose
  • Silkaj would constantly listen to this flow.
  • We could also benefit of having direct notifications.
  • But, Silkaj will not be able to run into a CI/CD job. It would need to run on a server.
• Request Discourse forum to know if the account exists
  • Remove every request and simply prefix all accounts with a @:
    • This drastically improve the speed and generate much less requests.
    • May be the @ could be extended later on, once the account have been renamed.
• Generate once the message for the two forums/Ğ1
  • We might only be keep Monnaie libre forum for Ğ1 exclusions
• Request Cesium+ to get the corresponding name.
• Ignore revoked identities
• Handle to start the list X days before now (pass an extra parameter).
• Display the reason of the exclusion:
  • membership expiration: check membership expiration date
  • lack of certifications: check current number of certifications
• Date of the exclusion

Forums Publication/CLI

• Publish on Discourse forums
• Allow renaming pseudo on the forums
• Add ability to pass a number of hours. One of the days and hours should be present. Both could be present.
• Ask with a confirmation to publish or not the message if --publish option is not passed, Keep --publish option.
• Option(s) to publish on only one of the two forums
• Stop publishing Ğ1 exclusions on Duniter forum.

Discourse API authentication change

• Discourse API change
• Header authentication handling in pydiscourse
• Published in pydiscourse v1.0.

Packaging

• pydiscourse is not in Debian, this dependency will prevent Silkaj to enter in Debian Bullseye #270 (closed):
  • Create DeathReaper package, and set Silkaj as a dependency:
    • Create client/python/deathreaper git repository/package based on Silkaj: Poetry, CI/CD
  • Introduce a module system in Silkaj:
    • Silkaj could install an extra deathreaper package:
    • The CLI could be extended through Click to add a command, then an import should be enough
  • Implement in DuniterPy the used HTTP REST call: create_post() to replace pydiscourse. Not nice, better let pydiscourse project handle the changes of the API. DuniterPy should stay focuse on Ğ1’s APIs.

Automation

• Executed at 9 AM and PM for Ğ1 and Ğ1-Test with a cron on my machine
• #388 (closed): Generate Docker image with Silkaj inside
  • Timezone of the image set to Paris
• Create clients/python/deathreaper repository to set the automation
  • Executed at 9 AM and PM for Ğ1 and Ğ1-Test
  • Based on the previously generated Docker image
  • Pass the API tokens through the CI secret system
• Could/Should be kept on a machine if all the time running: in case of listening exclusions on a WS
