From ec415d7166d607c92cf8f1af688f86e4b4731dff Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Fri, 2 Aug 2019 17:07:33 +0200 Subject: Add a test for auto-GC This currently fails because we're using POSIX file locks. So when the garbage collector opens and closes its own temproots file, it causes the lock to be released and then deleted by another GC instance. --- tests/gc-auto.sh | 59 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/local.mk | 4 +++- 2 files changed, 62 insertions(+), 1 deletion(-) create mode 100644 tests/gc-auto.sh (limited to 'tests') diff --git a/tests/gc-auto.sh b/tests/gc-auto.sh new file mode 100644 index 000000000000..1e91282d0f99 --- /dev/null +++ b/tests/gc-auto.sh @@ -0,0 +1,59 @@ +source common.sh + +clearStore + +garbage1=$(nix add-to-store --name garbage1 ./tarball.sh) +garbage2=$(nix add-to-store --name garbage2 ./tarball.sh) +garbage3=$(nix add-to-store --name garbage3 ./tarball.sh) + +fake_free=$TEST_ROOT/fake-free +export _NIX_TEST_FREE_SPACE_FILE=$fake_free +echo 1100 > $fake_free + +expr=$(cat < \$out/bar + echo 1... + sleep 2 + echo 100 > $fake_free + echo 2... + sleep 2 + echo 3... + [[ \$(ls \$NIX_STORE/*-garbage? | wc -l) = 1 ]] + ''; +} +EOF +) + +nix build -o $TEST_ROOT/result-A -L "($expr)" \ + --min-free 1000 --max-free 2000 --min-free-check-interval 1 & +pid=$! + +expr2=$(cat < \$out/bar + echo 1... + sleep 2 + echo 100 > $fake_free + echo 2... + sleep 2 + echo 3... + ''; +} +EOF +) + +nix build -o $TEST_ROOT/result-B -L "($expr2)" \ + --min-free 1000 --max-free 2000 --min-free-check-interval 1 + +wait "$pid" + +[[ foo = $(cat $TEST_ROOT/result-A/bar) ]] +[[ foo = $(cat $TEST_ROOT/result-B/bar) ]] diff --git a/tests/local.mk b/tests/local.mk index 1ff68348b3c7..261e4db0de88 100644 --- a/tests/local.mk +++ b/tests/local.mk @@ -3,7 +3,9 @@ check: nix_tests = \ init.sh hash.sh lang.sh add.sh simple.sh dependencies.sh \ - gc.sh gc-concurrent.sh \ + gc.sh \ + gc-concurrent.sh \ + gc-auto.sh \ referrers.sh user-envs.sh logging.sh nix-build.sh misc.sh fixed.sh \ gc-runtime.sh check-refs.sh filter-source.sh \ remote-store.sh export.sh export-graph.sh \ -- cgit 1.4.1
