Constants ¶
const MetadataDBFile = "metadata.db"
MetadataDBFile is the filename of the SQLite database inside a CodeDB directory.
Variables ¶
var BleveSubIndexNames = []string{"code", "diff", "comment"}
BleveSubIndexNames lists the bleve sub-indexes managed by Store, in the same order they are opened. Used by self-heal callers (daemon, doctor) so they don't have to hardcode the names.
var ErrCorrupt = fmt.Errorf("codedb index is corrupt")
ErrCorrupt indicates the index is corrupted and needs re-indexing.
var ErrFullReindexRequired = errors.New("full reindex required")
ErrFullReindexRequired is returned by RebuildBleveSubIndex when the requested sub-index (code/diff) cannot be repopulated from existing SQL data alone. Callers that hit this should fall back to a full reindex (wipe dataDir + run IndexLocalRepo) — the rebuild path is currently only safe for "comment" because ParseComments is gated on a per-blob SQL flag we can reset, while code/diff are populated only during the per-commit walk in IndexRepo and have no rebleve-from-blobs path yet.
Functions ¶
func CreateSchema ¶
CreateSchema initializes the SQLite tables and indexes, and runs all pending migrations. "Migrations" here include both schema migrations (idempotent ALTER/CREATE) and one-shot data repairs that recover from historical bugs (see migrateInvalidateGitHubMtimesForIssue474). New migrations should be appended at the end and gated by their own idempotency check (column existence, sentinel row, etc.).
func QueriesFromTx ¶ added in v0.6.0
func QueriesFromTx(tx *sql.Tx) *codedbsqlc.Queries
QueriesFromTx returns sqlc-generated typed queries bound to a transaction.
func RebuildBleveSubIndex ¶ added in v0.8.0
RebuildBleveSubIndex performs a targeted rebuild of a single bleve sub-index. Currently supported only for "comment", which can be fully repopulated from existing SQL data via the comments_parsed flag.
For "code" and "diff", this function returns ErrFullReindexRequired without modifying state — those sub-indexes are populated during the per-commit walk in IndexRepo, gated on `commits` SQL rows, and there is no rebleve-from-blobs path that could refill them from SQL alone. A surgical rebuild would leave search permanently empty; callers must fall back to a full reindex (wipe dataDir + IndexLocalRepo).
On success for "comment": removes bleve/comment/, recreates empty, and resets blobs.comments_parsed=0 so ParseComments re-extracts every blob on the next indexing pass. SQL/Open failures during the flag reset are surfaced as errors — a rebuild that "succeeds" with comments_parsed still set would silently leave search empty forever.
This function works without an open Store — by design, since Open fails when the sub-index is in the corrupt state we are recovering from.
Types ¶
type MaintenanceResult ¶ added in v0.6.0
type MaintenanceResult struct {
OrphanBlobsPruned int64
OldDiffsPruned int64
StaleSymbolsCount int64
Vacuumed bool
IntegrityOK bool
SizeBefore int64
SizeAfter int64
Duration time.Duration
}
MaintenanceResult captures what happened during codedb maintenance.
func (MaintenanceResult) TotalPruned ¶ added in v0.6.0
func (r MaintenanceResult) TotalPruned() int64
TotalPruned returns the total number of rows removed.
type MappingCorruptError ¶ added in v0.8.0
MappingCorruptError indicates that a Bleve sub-index is in a structurally broken state that bleve.Open cannot recover from on its own. The Name identifies which sub-index ("code", "diff", or "comment") so callers can perform a targeted rebuild via RebuildBleveSubIndex without nuking the whole dataDir.
Detected conditions (see isBleveIndexCorrupt):
- persisted `_mapping` doc is empty/missing in the latest snapshot, or
- the latest snapshot references segment IDs whose `.zap` files are missing on disk (the field-observed poison pill: bolt + mapping intact but a previous incomplete write left the snapshot pointing at segments that never landed)
Distinct from "real lock contention" (another goroutine/process actively writing): we only return this after a successful read-only bbolt open with 100ms timeout — a held exclusive lock blocks the read and we stay in the safe lock-contention path.
func (*MappingCorruptError) Error ¶ added in v0.8.0
func (e *MappingCorruptError) Error() string
type Store ¶
type Store struct {
CodeIndex bleve.Index
DiffIndex bleve.Index
CommentIndex bleve.Index
Root string
CombinedCodeIndex bleve.Index // alias of CodeIndex + all dirty indexes, or just CodeIndex
// contains filtered or unexported fields
}
Store wraps a SQLite database and Bleve full-text search indexes. All SQL access goes through the convenience methods below.
The store supports a two-tier architecture:
- Shared indexes (on-disk): committed content, shared across worktrees
- Dirty overlay (on-disk or in-memory): uncommitted worktree files, per-worktree
When a dirty overlay is attached, CombinedCodeIndex transparently merges results from both tiers via Bleve IndexAlias.
func Open ¶
Open opens (or creates) a Store at the given root directory. It creates the directory structure, initializes SQLite and Bleve indexes. If SQLite corruption is detected, the database is removed and ErrCorrupt is returned so the caller can trigger a full re-index.
func (*Store) AttachDirtyIndex ¶ added in v0.5.0
AttachDirtyIndex opens an existing on-disk dirty overlay index (built by the daemon) and aliases it with the shared CodeIndex for transparent search. Uses a default key; for multi-worktree support use AttachDirtyIndexByID.
func (*Store) AttachDirtyIndexByID ¶ added in v0.6.1
AttachDirtyIndexByID opens an on-disk dirty overlay and adds it to the overlay map under the given ID. If the ID is already attached, the old overlay is detached first. Rebuilds the combined alias to include all active overlays.
func (*Store) AttachDirtyOverlay ¶ added in v0.5.0
AttachDirtyOverlay creates an in-memory Bleve index for dirty worktree files and combines it with the shared CodeIndex via IndexAlias. Search code using CombinedCodeIndex will transparently search both. Primarily used in tests; production uses AttachDirtyIndex for on-disk overlays.
func (*Store) CheckIntegrity ¶
CheckIntegrity validates that the SQLite database and all Bleve indexes are healthy. Returns nil if everything is fine, ErrCorrupt otherwise.
func (*Store) DetachDirtyIndexByID ¶ added in v0.6.1
DetachDirtyIndexByID closes and removes a specific dirty overlay by ID. Rebuilds the combined alias with remaining overlays.
func (*Store) DetachDirtyOverlay ¶ added in v0.5.0
func (s *Store) DetachDirtyOverlay()
DetachDirtyOverlay closes all attached dirty overlays and resets CombinedCodeIndex.
func (*Store) DirtyCodeIndex ¶ added in v0.6.1
DirtyCodeIndex returns the first dirty overlay index found, or nil. Used by callers that need direct access to a dirty index (e.g., for indexing docs).
func (*Store) DirtyOverlayCount ¶ added in v0.6.1
DirtyOverlayCount returns the number of currently attached dirty overlays.
func (*Store) Maintain ¶ added in v0.6.0
func (s *Store) Maintain(ctx context.Context) MaintenanceResult
Maintain runs cleanup: prunes orphaned blobs, old diffs, and vacuums. Safe to call while the store is in use — all operations use transactions.
func (*Store) Queries ¶ added in v0.6.0
func (s *Store) Queries() *codedbsqlc.Queries
Queries returns the sqlc-generated typed queries bound to the store's DB.
func (*Store) QueryContext ¶
func (s *Store) QueryContext(ctx context.Context, query string, args ...interface{}) (*sql.Rows, error)
QueryContext executes a SQL query with context and returns the rows.
