From 4dff4f2201092f51992b72ceb100accb3796d550 Mon Sep 17 00:00:00 2001 From: Aaron Son Date: Wed, 8 Jul 2020 10:26:34 -0700 Subject: [PATCH] go/store/datas: commit.go: Start storing commit parents as a List instead of a Set. Commit parent order has meaning in our use case. The branch that gets merged into is always the first commit in the parents list. Up until this change, the noms layer stores commit parents as a Set, which is unordered and orders the parents based on their commit hash. This changes commit struct to carry both parents Set and parentsList List. CommitOptions supplies a ParentsList, but both get stored for backwards compatibility with existing dolt clients. This change does not include changes to start using the stored parentsList in things like ancestor traversal or `dolt log`. The intended migration is that the read logic will read from `parentsList` in a commit if it is present, and will fall back to the `parents` Set if it is not. Eventually we will be able to migrate to not writing `parents` Set anymore. There is no current plan to drop support for reading `parents` Set when `parentsList` is not available. --- go/libraries/doltcore/doltdb/doltdb.go | 68 +++++++------------- go/libraries/doltcore/sqle/sqlselect_test.go | 4 +- go/store/cmd/noms/noms_ds_test.go | 4 +- go/store/cmd/noms/noms_log_test.go | 14 ++-- go/store/cmd/noms/noms_merge.go | 7 +- go/store/cmd/noms/noms_merge_test.go | 28 ++++---- go/store/cmd/noms/noms_root.go | 5 ++ go/store/cmd/noms/noms_root_test.go | 4 +- go/store/cmd/noms/noms_show_test.go | 6 +- go/store/datas/commit.go | 23 ++++--- go/store/datas/commit_options.go | 4 +- go/store/datas/commit_test.go | 61 +++++++++++------- go/store/datas/database_common.go | 42 ++++++------ go/store/datas/database_test.go | 8 +-- go/store/datas/dataset_test.go | 8 +-- go/store/datas/pull_test.go | 32 ++++----- go/store/datas/puller_test.go | 23 +++---- go/store/types/list.go | 17 +++++ go/store/util/test/equals_ignore_hashes.go | 1 + 19 files changed, 197 insertions(+), 162 deletions(-) diff --git a/go/libraries/doltcore/doltdb/doltdb.go b/go/libraries/doltcore/doltdb/doltdb.go index 74a4408402..6fc9111b2c 100644 --- a/go/libraries/doltcore/doltdb/doltdb.go +++ b/go/libraries/doltcore/doltdb/doltdb.go @@ -138,8 +138,7 @@ func (ddb *DoltDB) WriteEmptyRepoWithCommitTime(ctx context.Context, name, email cm, _ := NewCommitMetaWithUserTS(name, email, "Initialize data repository", t) -
