Process improvements

Website

  • Discuss: historically remove many/most/all DJB-era .md docs from the source tree and preserve them on the website
    • Possibly false assumption: we were never going to update them
    • Possibly false assumption: they're not needed to grok/navigate the code
  • Start a next-release page (excluding it from the releases feed)

Git

  • Redo patch branches (where needed) like so:
    1. Commit (if needed) to restore context we've changed
    2. Commit-with-attribution: upstream patch, as verbatim as possible
    3. Commit (if needed) to fix compilation, style, etc.

Smoother PRs

  • Focus for a while on automating sources of confidence:
    • Integrate #225 (the patch checker) into GitHub Actions
    • Make sure automatically that Makefile rules listing dependencies on local include files are accurate
      • Also that "foo.h" includes come before <foo.h>
    • #189 Turn up warnings in local builds, fix everything that doesn't break patches, ratchet CI conf-cc -Wthis -Wthat to match
    • #48 Make regular use of code analysis tools
    • Reconsider alternatives to check, now that warnings are no longer rampant
    • Write more tests
      • Integrated tests, too (such as swaks)
  • Discuss whether to keep maintaining an in-tree CHANGES.md
    • If yes, make PRs fail checks when we forget
    • Eike: let's keep CHANGES.md for changes that are user-facing, e.g.
      • autobuild workflow changes
      • information about how we made it that isn't information about what's in there

Smoother releases

  • Make a small change, then cut another release, for the sole purpose of smoothing out the release process

1.10

Cleanups

  • #7 Stop redeclaring system functions
  • Remove everything from 1.09 "What's going away?" that we're sure now is the time

Patches to merge

Ideas to merge

  • #94 Sprinkle fsync() to make syncdir unnecessary

    • #232 Test qmail-inject recipient address qualification
  • #233 Import qmail-rcptcheck, qmail-rcptcheck-realrcptto, and qmail-rcptcheck-badrcptto
    • Enable realrcptto by default?
  • Import qmail-spp-spf

Other

  • #35 FHS (#2)
    • split conf-qmail in to conf-qmail-bin, conf-qmail-queue, conf-qmail-man, etc.
    • /var/qmail/DIR unless /var/qmail not in conf-qmail
    • Configuration sugar: ./configure && make && make install (#9)

    • #76 binary builds on openSUSE build service and locally
      • deb and rpm builds. (was #59)
    • FHS-aware (default on): /var/qmail contains symlinks to FHS-compatible paths

  • Incrementally integrate inbound STARTTLS and AUTH
  • Incrementally redesign qmail-remote for outbound TLS, AUTH, SIZE, PIPELINING, SMTPUTF8, IPv6

  • qmail-popup
  • qmail-pop3d

2.0

Breaking changes to the queue

Other breaking changes

  • Merge changes for high-volume installations that are harmless defaults in 2020 (taking care to migrate smoothly)
