[Git][ghc/ghc][master] ci: clone, don't copy when creating the cabal cache

This works because we only ever care about it if the respective job is not a cross job. We also statically detect darwin cross jobs in the same way. We only ever have darwin -> darwin cross jobs so this is enough to detect the host reliably. - - - - - 1 changed file: - .gitlab/ci.sh Changes: ===================================== .gitlab/ci.sh ===================================== @@ -737,7 +737,7 @@ function test_hadrian() { local test_compiler="$instdir/bin/${cross_prefix}ghc$exe" install_bindist _build/bindist/ghc-*/ "$instdir" - if [[ "${WINDOWS_HOST}" == "no" ]] && [ -z "${CROSS_TARGET:-}" ] + if [[ "${CI_JOB_NAME}" != *"windows"* ]] && [ -z "${CROSS_TARGET:-}" ] then run_hadrian \ test \ @@ -920,7 +920,16 @@ function save_test_output() { function save_cache () { info "Storing cabal cache from $CABAL_DIR to $CABAL_CACHE..." rm -Rf "$CABAL_CACHE" - cp -Rf "$CABAL_DIR" "$CABAL_CACHE" + if [[ "${CI_JOB_NAME}" == *"darwin"* ]]; then + # -a makes APFS behave like a COW file system + # From man CP(1) + # copy files using clonefile(2). + # Note that if clonefile(2) is not supported for the target filesystem, + # then cp will fallback to using copyfile(2) instead to ensure the copy still succeeds. + cp -Rcf "$CABAL_DIR" "$CABAL_CACHE" + else + cp -Rf "$CABAL_DIR" "$CABAL_CACHE" + fi } function clean() { @@ -1024,11 +1033,12 @@ case "$(uname)" in exe=".exe" # N.B. cabal-install expects CABAL_DIR to be a Windows path CABAL_DIR="$(cygpath -w "$CABAL_DIR")" - WINDOWS_HOST="yes" + ;; + Darwin*) + exe="" ;; *) exe="" - WINDOWS_HOST="no" ;; esac View it on GitLab: https://gitlab.haskell.org/ghc/ghc/-/commit/7fb51f543bd7bd3a5fd2170a7b634dc… -- View it on GitLab: https://gitlab.haskell.org/ghc/ghc/-/commit/7fb51f543bd7bd3a5fd2170a7b634dc… You're receiving this email because of your account on gitlab.haskell.org.

This reveals some modules that don't actually use anything *defined* in GHC.Internal.Base, and that can be pushed down a little in the import graph.

[Git][ghc/ghc][master] Introduce `-fimport-loaded-targets` GHCi flag
by Marge Bot (＠marge-bot) 18 Mar '26

18 Mar '26

Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: 86bd9bfc by fendor at 2026-03-17T23:46:09-04:00 Introduce `-fimport-loaded-targets` GHCi flag This new flag automatically adds all loaded targets to the GHCi session by adding an `InteractiveImport` for the loaded targets. By default, this flag is disabled, as it potentially increases memory-usage. This interacts with the flag `-fno-load-initial-targets` as follows: * If no module is loaded, no module is added as an interactive import. * If a reload loads up to a module, all loaded modules are added as interactive imports. * Unloading modules removes them from the interactive context. Fixes #26866 by rendering the use of a `-ghci-script` to achieve the same thing redundant. - - - - - 37 changed files: - compiler/GHC/Driver/Flags.hs - compiler/GHC/Driver/Session.hs - docs/users_guide/ghci.rst - ghc/GHCi/UI.hs - testsuite/tests/ghci/prog-mhu005/Makefile - testsuite/tests/ghci/prog-mhu005/all.T - + testsuite/tests/ghci/prog-mhu005/prog-mhu005b.script - + testsuite/tests/ghci/prog-mhu005/prog-mhu005b.stdout - + testsuite/tests/ghci/prog-mhu005/prog-mhu005c.script - + testsuite/tests/ghci/prog-mhu005/prog-mhu005c.stderr - + testsuite/tests/ghci/prog-mhu005/prog-mhu005c.stdout - + testsuite/tests/ghci/prog-mhu005/prog-mhu005d.script - + testsuite/tests/ghci/prog-mhu005/prog-mhu005d.stderr - + testsuite/tests/ghci/prog-mhu005/prog-mhu005d.stdout - + testsuite/tests/ghci/prog-mhu005/prog-mhu005e.script - + testsuite/tests/ghci/prog-mhu005/prog-mhu005e.stderr - + testsuite/tests/ghci/prog-mhu005/prog-mhu005e.stdout - + testsuite/tests/ghci/prog-mhu005/prog-mhu005f.script - + testsuite/tests/ghci/prog-mhu005/prog-mhu005f.stderr - + testsuite/tests/ghci/prog-mhu005/prog-mhu005f.stdout - + testsuite/tests/ghci/prog-mhu005/prog-mhu005g.script - + testsuite/tests/ghci/prog-mhu005/prog-mhu005g.stderr - + testsuite/tests/ghci/prog-mhu005/prog-mhu005g.stdout - testsuite/tests/ghci/prog022/Makefile - testsuite/tests/ghci/prog022/all.T - + testsuite/tests/ghci/prog022/ghci.prog022c.script - + testsuite/tests/ghci/prog022/ghci.prog022c.stderr - + testsuite/tests/ghci/prog022/ghci.prog022c.stdout - + testsuite/tests/ghci/prog022/ghci.prog022d.script - + testsuite/tests/ghci/prog022/ghci.prog022d.stderr - + testsuite/tests/ghci/prog022/ghci.prog022d.stdout - + testsuite/tests/ghci/prog022/ghci.prog022e.script - + testsuite/tests/ghci/prog022/ghci.prog022e.stderr - + testsuite/tests/ghci/prog022/ghci.prog022e.stdout - + testsuite/tests/ghci/prog022/ghci.prog022f.script - + testsuite/tests/ghci/prog022/ghci.prog022f.stderr - + testsuite/tests/ghci/prog022/ghci.prog022f.stdout The diff was not included because it is too large.
