Hannes Siebenhandl pushed to branch wip/fendor/ghci-multiple-home-units at Glasgow Haskell Compiler / GHC Commits: 61686ce0 by fendor at 2025-05-08T14:34:26+02:00 Add testcases for GHCi multiple home units Adds the following testcases: * Evaluate code with a single home unit using 'initMulti' initialisation logic * More complicated testcase with multiple home units, testing reload logic and code evaluation. - - - - - ef7f2859 by fendor at 2025-05-08T14:34:26+02:00 Make GHCi commands compatible with multiple home units FIXME: proper commit message There is one metric increase in this commit: ------------------------- Metric Increase: T4029 ------------------------- It is an increase from 14.4 MB to 16.1 MB (+11.8%) which sounds like a pretty big regression at first. However, we argue this increase is solely caused by using more data structures for managing multiple home units in the GHCi session. In particular, due to the design decision of using three home units, the base memory usage increases... but by how much? A big contributor is the `UnitState`, of which we have three now, which on its own 260 KB per instance. That makes an additional memory usage of 520 KB, already explaining a third of the overall memory usage increase. FIXME: re-investigate what the remaining 1 MB is. - - - - - b770b36f by fendor at 2025-05-08T14:34:26+02:00 FIXME: these test cases can be fixed by exploiting internals - - - - - 98 changed files: - compiler/GHC.hs - compiler/GHC/Driver/Downsweep.hs - compiler/GHC/Driver/Session.hs - compiler/GHC/Iface/Load.hs - compiler/GHC/Rename/Unbound.hs - compiler/GHC/Runtime/Context.hs - compiler/GHC/Runtime/Eval.hs - compiler/GHC/StgToByteCode.hs - compiler/GHC/StgToJS/Linker/Linker.hs - compiler/GHC/Tc/Module.hs - compiler/GHC/Types/Name/Ppr.hs - compiler/GHC/Unit/Env.hs - compiler/GHC/Unit/Home/Graph.hs - compiler/GHC/Unit/Types.hs - ghc/GHCi/UI.hs - ghc/GHCi/UI/Info.hs - ghc/GHCi/UI/Monad.hs - ghc/Main.hs - testsuite/driver/testlib.py - testsuite/tests/backpack/cabal/bkpcabal08/bkpcabal08.stdout - testsuite/tests/driver/T8526/T8526.stdout - testsuite/tests/driver/fat-iface/fat014.stdout - testsuite/tests/driver/multipleHomeUnits/multiGHCi.stderr - testsuite/tests/ghc-api/T6145.hs - testsuite/tests/ghc-api/annotations-literals/literals.hs - testsuite/tests/ghc-api/annotations-literals/parsed.hs - testsuite/tests/ghc-api/apirecomp001/myghc.hs - testsuite/tests/ghc-api/fixed-nodes/T1.hs - + testsuite/tests/ghci.debugger/scripts/break031/Makefile - + testsuite/tests/ghci.debugger/scripts/break031/a/A.hs - + testsuite/tests/ghci.debugger/scripts/break031/all.T - + testsuite/tests/ghci.debugger/scripts/break031/b/B.hs - + testsuite/tests/ghci.debugger/scripts/break031/break031a.script - + testsuite/tests/ghci.debugger/scripts/break031/break031a.stdout - + testsuite/tests/ghci.debugger/scripts/break031/break031b.script - + testsuite/tests/ghci.debugger/scripts/break031/break031b.stderr - + testsuite/tests/ghci.debugger/scripts/break031/break031b.stdout - + testsuite/tests/ghci.debugger/scripts/break031/unitA - + testsuite/tests/ghci.debugger/scripts/break031/unitB - testsuite/tests/ghci/linking/dyn/T3372.hs - + testsuite/tests/ghci/prog-mhu001/Makefile - + testsuite/tests/ghci/prog-mhu001/all.T - + testsuite/tests/ghci/prog-mhu001/e/E.hs - + testsuite/tests/ghci/prog-mhu001/prog-mhu001a.script - + testsuite/tests/ghci/prog-mhu001/prog-mhu001a.stdout - + testsuite/tests/ghci/prog-mhu001/prog-mhu001b.script - + testsuite/tests/ghci/prog-mhu001/prog-mhu001b.stdout - + testsuite/tests/ghci/prog-mhu001/prog-mhu001c.script - + testsuite/tests/ghci/prog-mhu001/prog-mhu001c.stderr - + testsuite/tests/ghci/prog-mhu001/prog-mhu001c.stdout - + testsuite/tests/ghci/prog-mhu001/unitE - + testsuite/tests/ghci/prog-mhu002/Makefile - + testsuite/tests/ghci/prog-mhu002/a/A.hs - + testsuite/tests/ghci/prog-mhu002/all.T - + testsuite/tests/ghci/prog-mhu002/b/B.hs - + testsuite/tests/ghci/prog-mhu002/c/C.hs - + testsuite/tests/ghci/prog-mhu002/d/Main.hs - + testsuite/tests/ghci/prog-mhu002/prog-mhu002.script - + testsuite/tests/ghci/prog-mhu002/prog-mhu002.stderr - + testsuite/tests/ghci/prog-mhu002/prog-mhu002.stdout - + testsuite/tests/ghci/prog-mhu002/prog-mhu002a.script - + testsuite/tests/ghci/prog-mhu002/prog-mhu002a.stderr - + testsuite/tests/ghci/prog-mhu002/prog-mhu002a.stdout - + testsuite/tests/ghci/prog-mhu002/unitA - + testsuite/tests/ghci/prog-mhu002/unitB - + testsuite/tests/ghci/prog-mhu002/unitC - + testsuite/tests/ghci/prog-mhu002/unitD - + testsuite/tests/ghci/prog-mhu003/Makefile - + testsuite/tests/ghci/prog-mhu003/a/A.hs - + testsuite/tests/ghci/prog-mhu003/all.T - + testsuite/tests/ghci/prog-mhu003/b/Foo.hs - + testsuite/tests/ghci/prog-mhu003/c/C.hs - + testsuite/tests/ghci/prog-mhu003/d/Foo.hs - + testsuite/tests/ghci/prog-mhu003/prog-mhu003.script - + testsuite/tests/ghci/prog-mhu003/prog-mhu003.stderr - + testsuite/tests/ghci/prog-mhu003/prog-mhu003.stdout - + testsuite/tests/ghci/prog-mhu003/unitA - + testsuite/tests/ghci/prog-mhu003/unitB - + testsuite/tests/ghci/prog-mhu003/unitC - + testsuite/tests/ghci/prog-mhu003/unitD - testsuite/tests/ghci/prog010/ghci.prog010.script - testsuite/tests/ghci/prog018/prog018.stdout - testsuite/tests/ghci/scripts/T13869.stdout - testsuite/tests/ghci/scripts/T13997.stdout - testsuite/tests/ghci/scripts/T17669.stdout - testsuite/tests/ghci/scripts/T18330.stdout - testsuite/tests/ghci/scripts/T1914.stdout - testsuite/tests/ghci/scripts/T20217.stdout - testsuite/tests/ghci/scripts/T20587.stdout - testsuite/tests/ghci/scripts/T21110.stderr - testsuite/tests/ghci/scripts/T6105.stdout - testsuite/tests/ghci/scripts/T8042.stdout - testsuite/tests/ghci/scripts/T8042recomp.stdout - testsuite/tests/ghci/scripts/ghci024.stdout - testsuite/tests/ghci/scripts/ghci024.stdout-mingw32 - testsuite/tests/ghci/scripts/ghci058.script - testsuite/tests/ghci/should_run/TopEnvIface.stdout - testsuite/tests/quasiquotation/T7918.hs The diff was not included because it is too large.
