Alan Zimmerman pushed to branch wip/az/epa-tidy-locatedxxx-8 at Glasgow Haskell Compiler / GHC Commits: 0f64f348 by Cheng Shao at 2026-07-16T15:41:08+00:00 ci: add missing docker permission workaround in abi-test job - - - - - 660cb239 by Cheng Shao at 2026-07-16T19:37:48+00:00 bindist: Fix make install -j race condition on macos/freebsd This patch fixes make install -j race condition on macos/freebsd. BSD install fails with EEXIST when multiple install processes concurrently create the same prefix directory. So we add an `install_dirs` prerequisite job that sequentially creates the directories for subsequent jobs to work with. Fixes #27499.

This only affects ghc ci logic, the user-facing default is up to distributors and is still `-j1`. Closes #27029. - - - - - d5ae6906 by Adam Gundry at 2026-07-17T04:57:43-04:00 Mark various language extension flags as deprecated (see #27329) The following language extensions are now deprecated: - AlternativeLayoutRule - AlternativeLayoutRuleTransitional - ParallelArrays - PolymorphicComponents - Rank2Types In addition, the warning `-Walternative-layout-rule-transitional` has been marked as deprecated, as it is emitted only under the deprecated extension `XAlternativeLayoutRuleTransitional`. - - - - - fe3b059c by Andrew Lelechenko at 2026-07-17T04:58:26-04:00 base: re-export GHC.Environment.getFullArgs from System.Environment CLC proposal https://github.com/haskell/core-libraries-committee/issues/431 - - - - - 57ec828f by Alan Zimmerman at 2026-07-18T11:47:17+01:00 EPA: Keep decls together in ClassDecl Similar to 1718230f4d3d19d8c49c0e5d496cb0fb6f399528 for HsValBindsLR, this commit updates ClassDecl so that it no longer splits out the assorted `LHsDecl GhcPs` until the renamer. It does this by inserting a type family (separate from the classic TTG one) for this. So data TyClDecl ... | ClassDecl { ... tcdDecls :: XClassDecls pass with type instance XClassDecls GhcPs = [LHsDecl GhcPs] type instance XClassDecls GhcRn = ClassDeclX GhcRn type instance XClassDecls GhcTc = ClassDeclX GhcTc data ClassDeclX pass = ClassDeclX { tcdSigs :: [LSig pass], -- ^ Methods' signatures tcdMeths :: LHsBinds pass, -- ^ Default methods tcdATs :: [LFamilyDecl pass], -- ^ Associated types; tcdATDefs :: [LTyFamDefltDecl pass], -- ^ Associated type defaults tcdDocs :: [LDocDecl pass] -- ^ Haddock docs } - - - - - 91 changed files: - .gitlab-ci.yml - .gitlab/ci.sh - + changelog.d/T27329 - + changelog.d/fix-make-install-j - compiler/GHC/Driver/Flags.hs - compiler/GHC/Driver/Session.hs - compiler/GHC/Hs/Decls.hs - compiler/GHC/Hs/Instances.hs - compiler/GHC/Hs/Stats.hs - compiler/GHC/Hs/Utils.hs - compiler/GHC/HsToCore/Docs.hs - compiler/GHC/HsToCore/Quote.hs - compiler/GHC/Iface/Ext/Ast.hs - compiler/GHC/Parser/PostProcess.hs - compiler/GHC/Parser/PostProcess/Haddock.hs - compiler/GHC/Rename/Module.hs - compiler/GHC/Tc/TyCl.hs - compiler/GHC/Tc/TyCl/Class.hs - compiler/GHC/Tc/Types/Rank.hs - compiler/GHC/ThToHs.hs - compiler/Language/Haskell/Syntax/Binds.hs - compiler/Language/Haskell/Syntax/Decls.hs - compiler/Language/Haskell/Syntax/Extension.hs - docs/users_guide/expected-undocumented-flags.txt - docs/users_guide/exts/rank_polymorphism.rst - docs/users_guide/exts/static_pointers.rst - hadrian/bindist/Makefile - libraries/base/changelog.md - libraries/base/src/System/Environment.hs - libraries/ghc-internal/ghc-internal.cabal.in - testsuite/tests/backpack/should_compile/T13149.bkp - testsuite/tests/determinism/determ017/A.hs - testsuite/tests/ghci/scripts/T12005.script - testsuite/tests/haddock/haddock_examples/haddock.Test.stderr - testsuite/tests/haddock/perf/Fold.hs - testsuite/tests/haddock/should_compile_flag_haddock/T17544.stderr - testsuite/tests/haddock/should_compile_flag_haddock/T17544_kw.stderr - testsuite/tests/indexed-types/should_fail/T7354.hs - testsuite/tests/interface-stability/base-exports.stdout - testsuite/tests/interface-stability/base-exports.stdout-javascript-unknown-ghcjs - testsuite/tests/interface-stability/base-exports.stdout-mingw32 - testsuite/tests/layout/layout001.stdout - testsuite/tests/layout/layout002.stdout - testsuite/tests/layout/layout003.stdout - testsuite/tests/layout/layout004.stdout - testsuite/tests/layout/layout005.stdout - testsuite/tests/layout/layout006.stdout - testsuite/tests/layout/layout007.stdout - testsuite/tests/layout/layout008.stdout - testsuite/tests/layout/layout009.stdout - testsuite/tests/linear/should_compile/T1735Min.hs - testsuite/tests/parser/should_compile/DumpRenamedAst.stderr - testsuite/tests/parser/should_compile/DumpSemis.stderr - + testsuite/tests/parser/should_compile/T13087.stderr - testsuite/tests/parser/should_compile/T20452.stderr - testsuite/tests/parser/should_fail/T8431.stderr - testsuite/tests/parser/should_fail/readFail038.stderr - testsuite/tests/perf/compiler/T3064.hs - testsuite/tests/polykinds/T7594.hs - testsuite/tests/printer/Test24533.stdout - testsuite/tests/programs/thurston-modular-arith/Main.hs - testsuite/tests/rts/ipe/IpeStats/Fold.hs - testsuite/tests/simplCore/should_compile/T11562.hs - testsuite/tests/simplCore/should_run/T3591.hs - testsuite/tests/typecheck/should_compile/DeepSubsumption02.hs - testsuite/tests/typecheck/should_compile/T12507.hs - testsuite/tests/typecheck/should_compile/T13951.hs - testsuite/tests/typecheck/should_compile/T18920.hs - testsuite/tests/typecheck/should_compile/T2595.hs - testsuite/tests/typecheck/should_compile/T7541.hs - testsuite/tests/typecheck/should_fail/T6069.stderr - testsuite/tests/typecheck/should_fail/T7368a.hs - testsuite/tests/typecheck/should_run/T1735_Help/Basics.hs - testsuite/tests/typecheck/should_run/T3731-short.hs - testsuite/tests/typecheck/should_run/T3731.hs - testsuite/tests/typecheck/should_run/church.hs - testsuite/tests/typecheck/should_run/tcrun008.hs - testsuite/tests/typecheck/should_run/tcrun017.hs - testsuite/tests/typecheck/should_run/tcrun026.hs - testsuite/tests/typecheck/should_run/tcrun035.hs - testsuite/tests/typecheck/should_run/tcrun036.hs - utils/check-exact/ExactPrint.hs - utils/check-exact/Utils.hs - utils/haddock/haddock-api/src/Haddock/Backends/Hoogle.hs - utils/haddock/haddock-api/src/Haddock/Backends/LaTeX.hs - utils/haddock/haddock-api/src/Haddock/Backends/Xhtml/Decl.hs - utils/haddock/haddock-api/src/Haddock/Convert.hs - utils/haddock/haddock-api/src/Haddock/GhcUtils.hs - utils/haddock/haddock-api/src/Haddock/Interface/Create.hs - utils/haddock/haddock-api/src/Haddock/Interface/Rename.hs - utils/haddock/haddock-api/src/Haddock/Types.hs The diff was not included because it is too large.
