Wiki upgrades: Next steps

Related ticket: https://github.com/openstreetmap/operations/issues/1210]

  • Aim: replace the operating system and upgrade to the newest long-term supported version of MediaWiki.
    • Tom has done the staging version, and resolved some bugs.
  • Steps: Read-only, dump sql, upgrade OS (in-place), return-data (from in-place), wiki upgrade.
  • Server: konqi.
  • Date and time: Saturday 26 April 2025 at 10am (9am UTC).
  • Duration estimate to be included in the announcement: 8 hours.

Minh offered to help.

Suggestion: Keep the test instance and test some modules that people have asked for.

Action item: Minh to post about the OSM wiki downtime planned for 10am (9am UTC) Saturday 26 April 2025.

Upgrade primary database server

Current setup: primary DB server running PostgreSQL 15, while the tile servers are running 16.

PostgreSQL 16:

  • introduces the new custom dump compressor, which could improve backup performance.
  • uses pg_dump to restore to SQL.

On upgrade

  • We need to fix planet dump first.
  • If we switch to zStandard and we tweak the compression level slightly we could theoretically gain double the performance while keeping the same compressed size

Other point mentioned during discussion

  • zStandard is a lot faster than gzip, depending on the compression level.

Any other business

Grant's tech talk

  • Grant plans to do an OSM chef - how to contribute - talk, open to anyone, in the next couple of months.
  • The Chef repo contains a contribution guide, which shows how to run the test.

OSM core software development facilitator

Minh is the new OSM core software development facilitator.
