Things that definitely need to be done:

• Work out Haddock story

Backpack critpath:

• ComponentEnabledSpec Introduce new ComponentEnabledSpec, removing testEnabled/benchmarkEna… #3542
• Test suite runners should take CLBI. Branch: cabal-staging
  • Refactor into Types modules Proposed reorganization of Cabal library types #3590
  • Refactor LocalBuildInfo to make sense Proposed redesign of LocalBuildInfo and BuildTarget interface #3589
  • PUNTED: Move when test/bench get expanded to configure time Refactor tests/benchmarks to be expanded at configure time #3599
• Fix build targets to use unit IDs
• Rebase Backpack
• Get per-package instantiate working
• Get cabal-install to instantiate Backpack packages
• --cabal-file Implement --cabal-file, allows multiple Cabal files in directory #3553
• Internal libraries don't work in dependency solver (see my comment which I never implemented in IndexConversion) (But maybe it's OK?)
• Merge Backpack. Branch: backpack Backpack #3672
• backpack-includes: p (* as *.ByteString) support

GHC stuff

• Stop repeatedly reading interfaces; do NO performance harm w/o Backpack
• Update Cabal to HEAD https://phabricator.haskell.org/D2442
  • Haddock on Cabal performance regression (NOT problem, just added extra modules so Haddock will take more memory, of course.)
• Unwind the knot-tying patchset
  • Performance regression T10370 (not actually perf regression)
  • Test framework regression
  • Knot tying regression T8184
• Backpack proper
• Just for fun:
  • Recursive type synonym handling

Per-component build

• Per-component configure. Branch: cabal-shake Handle apparent package dependency cycles due to test suites / benchmarks #1575
• cabal install bits
• new-build registering local libraries for executable only
• fix sdist bug so we can actually benefit from building only one component Replace new-build's call to sdist with new command which lists sources of things that will be built #3401

Things I've agreed to do

• Preprocessor redesign Moving location where library build files are generated #3545
• BC libraries -> library/subLibraries BC fix: libraries -> library/subLibraries (#3574) #3580. Branch: convenience-bc
  • Check that internal library doesn't have same name as package name
  • Test that LibV09 test suite named same as package name does the right thing
  • Check that libName is not Nothing for subLibraries.
  • Undo HookedBuildInfo change
• Put command line flag parsing back into Travis script
• Haddock fixes from cabal-install uses internal libraries. #3533

Backpack on base. (Why? base is pegged to a GHC version, so there's no worry about people needing to support multiple versions of a package at the same time.)

• Teach cabal-install how to build a new copy of base
• Maybe https://ghc.haskell.org/trac/ghc/ticket/10266 ?
• Teach build system how to build Backpack packages

@ezyang are you planning on this issues?

I think it would be best to assume these are not getting done :>
