shared cache meeting 20200923

Present at the meeting:

• Andrey Mokhov (@snowleopard)
• Jérémie Dimino (@jeremiedimino)
• Quentin Hocquet (@mefyl)

Discussed

• Andrey and Quentin get similar performance results in their respective tests.
• Upload and download is way too slow, which will most likely be improved with HTTP Keep-alive.
  • Using keep-alive with Cohttp produces invalid HTTP request, which Quentin is looking into.
  • There might be some bugs on the httpaf side too - investigation in progress.
• Andrey had artifacts corruption on download, which Quentin had not on js/universe, a vary large repository.
  • It could be because Quentin is using the new Async branch, which should be merged ASAP.
  • Andrey suggested it might be a race condition. However, everything is atomic so shouldn’t be happening.
  • Quentin will look how to add a lock file so that we use exactly the same versions of the deps.
• No progress on Krb yet as the focus is on performances.

Next steps

• Quentin
  • Merge the Async branch.
  • Provide a lock file of the dependencies.
  • Fix Cohttp (and potentiall httpaf) to make connection keep-alive work and recheck performances.
• Andrey
  • Test again with the Async branch merged and the lock file
