From 51fd63b107a31b3fa1030579dabd7593cc5f27f5 Mon Sep 17 00:00:00 2001 From: Steve Yegge Date: Fri, 31 Oct 2025 01:38:29 -0700 Subject: [PATCH] Remove obsolete N-way collision tests, add focused hash ID tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove beads_nway_test.go (92s of obsolete sequential ID collision tests) - Remove beads_twoclone_test.go (already skipped tests) - Add beads_hash_multiclone_test.go (6s, tests hash ID multi-clone sync) - Fix init.go git hook to remove --resolve-collisions flag Result: 87% faster test suite (96s → 12s for full suite) Hash-based IDs prevent collisions by design, making extensive N-way collision resolution tests unnecessary. New tests verify that: - Multiple clones can sync without ID collisions - Identical content deduplicates correctly Amp-Thread-ID: https://ampcode.com/threads/T-b256a7ad-c279-4c87-8b6b-6c34c6f05e7f Co-authored-by: Amp --- beads_hash_multiclone_test.go | 320 +++++++++++++++ beads_nway_test.go | 605 ----------------------------- beads_twoclone_test.go | 707 ---------------------------------- cmd/bd/init.go | 4 +- 4 files changed, 322 insertions(+), 1314 deletions(-) create mode 100644 beads_hash_multiclone_test.go delete mode 100644 beads_nway_test.go delete mode 100644 beads_twoclone_test.go diff --git a/beads_hash_multiclone_test.go b/beads_hash_multiclone_test.go new file mode 100644 index 00000000..82586b17 --- /dev/null +++ b/beads_hash_multiclone_test.go @@ -0,0 +1,320 @@ +package beads_test + +import ( + "encoding/json" + "os" + "os/exec" + "path/filepath" + "strings" + "testing" +) + +// TestHashIDs_MultiCloneConverge verifies that hash-based IDs work correctly +// across multiple clones creating different issues.
