New struct RevAndVersion handles marshal/unmarshal of the rev property, and supports rev only (string) and rev/src/version (map). New structs SyncDataJSON and SyncDataAlias are used to encapsulate this handling at the persistence/marshalling layer. This avoids changes to use of SyncData.CurrentRev, and also avoids potential errors by not duplicating cv in SyncData. * Test updates based on PR feedback --- channels/log_entry.go | 4 +- db/change_cache.go | 8 +++ db/changes.go | 2 +- db/changes_view.go | 7 +-- db/crud.go | 13 ++-- db/database.go | 4 +- db/database_test.go | 84 ++++++++++++++++++++++++- db/document.go | 87 ++++++++++++++++++++++++-- db/document_test.go | 90 +++++++++++++++++++++++++++ db/hybrid_logical_vector.go | 32 +++++++++- db/hybrid_logical_vector_test.go | 10 ++- db/import_test.go | 13 ++-- db/query.go | 20 +++--- db/util_testing.go | 26 ++++++++ rest/api_test.go | 7 +-- rest/changes_test.go | 2 + rest/changestest/changes_api_test.go | 93 ++++++++++------------------ rest/importtest/import_test.go | 42 ++++++------- rest/utilities_testing.go | 5 +- 19 files changed, 419 insertions(+), 130 deletions(-) diff --git a/channels/log_entry.go b/channels/log_entry.go index a999cd1697..ee9d5b211f 100644 --- a/channels/log_entry.go +++ b/channels/log_entry.go @@ -47,11 +47,13 @@ type LogEntry struct { func (l LogEntry) String() string { return fmt.Sprintf( - "seq: %d docid: %s revid: %s collectionID: %d", + "seq: %d docid: %s revid: %s collectionID: %d source: %s version: %d", l.Sequence, l.DocID, l.RevID, l.CollectionID, + l.SourceID, + l.Version, ) } diff --git a/db/change_cache.go b/db/change_cache.go index 75083d3d36..ed8a5358f1 100644 --- a/db/change_cache.go +++ b/db/change_cache.go @@ -129,6 +129,14 @@ func (entry *LogEntry) IsUnusedRange() bool { return entry.DocID == "" && entry.EndSequence > 0 } +func (entry *LogEntry) SetRevAndVersion(rv RevAndVersion) { + entry.RevID = rv.RevTreeID + if rv.CurrentSource != "" { + entry.SourceID = rv.CurrentSource + entry.Version = base.HexCasToUint64(rv.CurrentVersion) + } +} + type LogEntries []*LogEntry // A priority-queue of LogEntries, kept ordered by increasing sequence #. diff --git a/db/changes.go b/db/changes.go index 6c2ce655c0..cde48188d6 100644 --- a/db/changes.go +++ b/db/changes.go @@ -57,7 +57,7 @@ type ChangeEntry struct { principalDoc bool // Used to indicate _user/_role docs Revoked bool `json:"revoked,omitempty"` collectionID uint32 - CurrentVersion *Version `json:"current_version,omitempty"` // the current version of the change entry + CurrentVersion *Version `json:"-"` // the current version of the change entry.

Switches the docs struct to a map of a new BlipTesterDoc struct, instead of a map of revs per document. BlipTesterDoc still maintains a history of all rev messages received (revMessageHistory) to support test evaluation of received messages, but also defines a linear revTreeId history or an HLV (depending on protocol enabled for the test). Includes a refactor of revID to revTreeID in RevAndVersion, as a step toward standardizing ‘revID’ as the generic property used during replication (which can be currentRev or cv), and revTreeID as a traditional revtree revision ID. * Fixes based on PR review --- db/blip_sync_context.go | 2 +- db/crud.go | 2 +- db/hybrid_logical_vector.go | 24 +- db/hybrid_logical_vector_test.go | 2 +- db/revision_cache_bypass.go | 6 +- db/revision_cache_lru.go | 6 +- rest/access_test.go | 20 +- rest/adminapitest/admin_api_test.go | 10 +- rest/api_test.go | 4 +- rest/api_test_helpers.go | 6 +- rest/attachment_test.go | 56 +-- rest/audit_test.go | 71 +-- rest/blip_api_attachment_test.go | 9 +- rest/blip_api_crud_test.go | 35 +- rest/blip_api_delta_sync_test.go | 6 +- rest/blip_client_test.go | 434 +++++++++++------- rest/bulk_api.go | 2 +- rest/changes_test.go | 8 +- rest/changestest/changes_api_test.go | 10 +- rest/importtest/import_test.go | 4 +- rest/replicatortest/replicator_test.go | 14 +- rest/replicatortest/replicator_test_helper.go | 2 +- rest/revocation_test.go | 4 +- rest/utilities_testing.go | 20 +- rest/utilities_testing_resttester.go | 32 +- 25 files changed, 455 insertions(+), 334 deletions(-) diff --git a/db/blip_sync_context.go b/db/blip_sync_context.go index 49e806c3d5..584cfc496b 100644 --- a/db/blip_sync_context.go +++ b/db/blip_sync_context.go @@ -631,7 +631,7 @@ func (bsc *BlipSyncContext) sendRevision(ctx context.Context, sender *blip.Sende docRev, originalErr = handleChangesResponseCollection.GetRev(ctx, docID, revID, true, nil) } else { // extract CV string rev representation - version, vrsErr := CreateVersionFromString(revID) + version, vrsErr := ParseVersion(revID) if vrsErr != nil { return vrsErr } diff --git a/db/crud.go b/db/crud.go index 2d82b2a70d..8977a48e43 100644 --- a/db/crud.go +++ b/db/crud.go @@ -2381,7 +2381,7 @@ func (db *DatabaseCollectionWithUser) updateAndReturnDoc(ctx context.Context, do Attachments: doc.Attachments, Expiry: doc.Expiry, Deleted: doc.History[newRevID].Deleted, - hlvHistory: doc.HLV.toHistoryForHLV(), + hlvHistory: doc.HLV.ToHistoryForHLV(), CV: &Version{SourceID: doc.HLV.SourceID, Value: doc.HLV.Version}, } diff --git a/db/hybrid_logical_vector.go b/db/hybrid_logical_vector.go index 90d0c572c2..2648c1a560 100644 --- a/db/hybrid_logical_vector.go +++ b/db/hybrid_logical_vector.go @@ -70,7 +70,7 @@ func CreateVersion(source, version string) Version { } } -func CreateVersionFromString(versionString string) (version Version, err error) { +func ParseVersion(versionString string) (version Version, err error) { timestampString, sourceBase64, found := strings.Cut(versionString, "@") if !found { return version, fmt.Errorf("Malformed version string %s, delimiter not found", versionString) @@ -80,6 +80,16 @@ func CreateVersionFromString(versionString string) (version Version, err error) return version, nil } +func ParseDecodedVersion(versionString string) (version DecodedVersion, err error) { + timestampString, sourceBase64, found := strings.Cut(versionString, "@") + if !found { + return version, fmt.Errorf("Malformed version string %s, delimiter not found", versionString) + } + version.SourceID = sourceBase64 + version.Value = base.HexCasToUint64(timestampString) + return version, nil +} + // String returns a Couchbase Lite-compatible string representation of the version. func (v DecodedVersion) String() string { timestamp := string(base.Uint64CASToLittleEndianHex(v.Value)) @@ -178,7 +188,7 @@ func (hlv *HybridLogicalVector) AddVersion(newVersion Version) error { if currPVVersionCAS < hlvVersionCAS { hlv.PreviousVersions[hlv.SourceID] = hlv.Version } else { - return fmt.Errorf("local hlv has current source in previous versiosn with version greater than current version.

On proposeChanges, checks whether the incoming CV and parent version represent a new document, known version, valid update, or conflict. Uses the same handling as revTreeID (conflict if parent version isn’t the server’s current version), with the additional non-conflict case where the incoming CV and server CV share the same source and the incoming CV is a newer version. For the incoming rev, detects conflict based on the incoming cv (based on the implicit hierarchy in an HLV, where cv > pv > mv). Includes some test helpers to support writing tests with simplified versions (e.g. 1@abc) while still asserting for encoded source and version. * Test fixes * Fixes/cleanup based on PR review --------- Co-authored-by: Gregory Newman-Smith --- base/util.go | 11 ++ db/blip_handler.go | 84 +++++++--- db/crud.go | 83 ++++++++-- db/crud_test.go | 50 +++--- db/database_test.go | 134 ++++++++++++++++ db/document.go | 13 +- db/document_test.go | 2 +- db/hybrid_logical_vector.go | 164 +++++++++++++++++--- db/hybrid_logical_vector_test.go | 254 +++++++++++++++++++++++++------ db/revision_cache_interface.go | 1 + db/utilities_hlv_testing.go | 97 +++++++++++- rest/attachment_test.go | 10 +- rest/blip_api_attachment_test.go | 20 +-- rest/blip_api_crud_test.go | 103 ++++++++++++- rest/blip_api_delta_sync_test.go | 24 ++- rest/blip_client_test.go | 14 +- 16 files changed, 892 insertions(+), 172 deletions(-) diff --git a/base/util.go b/base/util.go index 99170291df..1a9f1b2fbf 100644 --- a/base/util.go +++ b/base/util.go @@ -1033,6 +1033,17 @@ func Uint64CASToLittleEndianHex(cas uint64) []byte { return encodedArray } +// Converts a string decimal representation ("100") to little endian hex string ("0x64") +func StringDecimalToLittleEndianHex(value string) (string, error) { + intValue, err := strconv.ParseUint(value, 10, 64) + if err != nil { + return "", err + } + hexValue := Uint64CASToLittleEndianHex(intValue) + return string(hexValue), nil + +} + func Crc32cHash(input []byte) uint32 { // crc32.MakeTable already ensures singleton table creation, so shouldn't need to cache. table := crc32.MakeTable(crc32.Castagnoli) diff --git a/db/blip_handler.go b/db/blip_handler.go index a052625e0b..f1767d563e 100644 --- a/db/blip_handler.go +++ b/db/blip_handler.go @@ -824,12 +824,18 @@ func (bh *blipHandler) handleProposeChanges(rq *blip.Message) error { for i, change := range changeList { docID := change[0].(string) - revID := change[1].(string) + rev := change[1].(string) // rev can represent a RevTree ID or HLV current version parentRevID := "" if len(change) > 2 { parentRevID = change[2].(string) } - status, currentRev := bh.collection.CheckProposedRev(bh.loggingCtx, docID, revID, parentRevID) + var status ProposedRevStatus + var currentRev string + if bh.activeCBMobileSubprotocol >= CBMobileReplicationV4 { + status, currentRev = bh.collection.CheckProposedVersion(bh.loggingCtx, docID, rev, parentRevID) + } else { + status, currentRev = bh.collection.CheckProposedRev(bh.loggingCtx, docID, rev, parentRevID) + } if status == ProposedRev_OK_IsNew { // Remember that the doc doesn't exist locally, in order to optimize the upcoming Put: bh.collectionCtx.notePendingInsertion(docID) @@ -971,6 +977,10 @@ func (bh *blipHandler) processRev(rq *blip.Message, stats *processRevStats) (err } }() + if bh.activeCBMobileSubprotocol >= CBMobileReplicationV4 && bh.conflictResolver != nil { + return base.HTTPErrorf(http.StatusNotImplemented, "conflict resolver handling (ISGR) not yet implemented for v4 protocol") + } + // throttle concurrent revs if cap(bh.inFlightRevsThrottle) > 0 { select { @@ -989,13 +999,13 @@ func (bh *blipHandler) processRev(rq *blip.Message, stats *processRevStats) (err // Doc metadata comes from the BLIP message metadata, not magic document properties: docID, found := revMessage.ID() - revID, rfound := revMessage.Rev() + rev, rfound := revMessage.Rev() if !found || !rfound { - return base.HTTPErrorf(http.StatusBadRequest, "Missing docID or revID") + return base.HTTPErrorf(http.StatusBadRequest, "Missing docID or rev") } if bh.readOnly { - return base.HTTPErrorf(http.StatusForbidden, "Replication context is read-only, docID: %s, revID:%s", docID, revID) + return base.HTTPErrorf(http.StatusForbidden, "Replication context is read-only, docID: %s, rev:%s", docID, rev) } base.DebugfCtx(bh.loggingCtx, base.KeySyncMsg, "#%d: Type:%s %s", bh.serialNumber, rq.Profile(), revMessage.String()) @@ -1015,7 +1025,7 @@ func (bh *blipHandler) processRev(rq *blip.Message, stats *processRevStats) (err return err } if removed, ok := body[BodyRemoved].(bool);
