From 844e0c92aabd056b4f241864dd12f3c705d3f535 Mon Sep 17 00:00:00 2001 From: across Date: Sun, 27 Sep 2026 04:57:10 +0530 Subject: [PATCH 01/21] feat(store): checksummed migration ledger, indexes and provenance schema - schema_migrations gains a checksum column; existing 0.0.1 ledgers are backfilled, and Migrate refuses unknown or future versions, gaps and edited migrations. Migrations run under BEGIN IMMEDIATE on one connection so concurrent first opens serialize. - migration 4 adds the indexes the list/search queries use. - migration 5 adds import provenance (content hash, size, parser version, redaction/import status), session lineage and checkpoint bundle columns, and the context_manifests, context_items, handoffs and evidence_bundles tables. - Open retries the connection pragmas on SQLITE_BUSY. Migrations 1-3 are byte-identical, so 0.0.1 databases upgrade in place. --- internal/store/migrate.go | 295 ++++++++++++++++++++++++++++++--- internal/store/migrate_test.go | 291 ++++++++++++++++++++++++++++++-- internal/store/store.go | 32 +++- 3 files changed, 576 insertions(+), 42 deletions(-) diff --git a/internal/store/migrate.go b/internal/store/migrate.go index f080002..ead940b 100644 --- a/internal/store/migrate.go +++ b/internal/store/migrate.go @@ -1,50 +1,202 @@ package store import ( + "context" + "crypto/sha256" "database/sql" + "errors" "fmt" ) -// migrations are numbered and transactional where possible. -var migrations = []struct { +type migration struct { Version int SQL string -}{ +} + +// migrations are numbered and transactional where possible. +var migrations = []migration{ {1, migration001}, {2, migration002}, {3, migration003}, + {4, migration004}, + {5, migration005}, } func Migrate(db *sql.DB) error { - if _, err := db.Exec(`CREATE TABLE IF NOT EXISTS schema_migrations (version INTEGER PRIMARY KEY, applied_at TEXT NOT NULL)`); err != nil { + if db == nil { + return errors.New("migrate: nil database") + } + + ctx := context.Background() + conn, err := db.Conn(ctx) + if err != nil { + return fmt.Errorf("migrate: acquire connection: %w", err) + } + defer conn.Close() + + if _, err := conn.ExecContext(ctx, `PRAGMA busy_timeout=5000`); err != nil { + return fmt.Errorf("migrate: set busy timeout: %w", err) + } + if _, err := conn.ExecContext(ctx, `PRAGMA foreign_keys=ON`); err != nil { + return fmt.Errorf("migrate: enable foreign keys: %w", err) + } + if _, err := conn.ExecContext(ctx, `BEGIN IMMEDIATE`); err != nil { + return fmt.Errorf("migrate: begin immediate transaction: %w", err) + } + + committed := false + defer func() { + if !committed { + _, _ = conn.ExecContext(context.Background(), `ROLLBACK`) + } + }() + + if err := migrateLocked(ctx, conn); err != nil { return err } - var maxV int - _ = db.QueryRow(`SELECT COALESCE(MAX(version),0) FROM schema_migrations`).Scan(&maxV) + if _, err := conn.ExecContext(ctx, `COMMIT`); err != nil { + return fmt.Errorf("migrate: commit: %w", err) + } + committed = true + return nil +} + +func migrateLocked(ctx context.Context, conn *sql.Conn) error { + manifest, latest, err := migrationManifest() + if err != nil { + return err + } + if _, err := conn.ExecContext(ctx, schemaMigrationsDDL); err != nil { + return fmt.Errorf("migrate: create migration ledger: %w", err) + } + legacyChecksums, err := ensureMigrationChecksumColumn(ctx, conn) + if err != nil { + return err + } + applied, legacy, err := readAppliedMigrations(ctx, conn, manifest, latest, legacyChecksums) + if err != nil { + return err + } + for version, checksum := range legacy { + if _, err := conn.ExecContext(ctx, `UPDATE schema_migrations SET checksum=?

records render with textContent only. - `/?token=` sets an HttpOnly SameSite=Strict cookie and redirects so the token leaves the address bar; the UI fetches same-origin. - --addr must be loopback; Host/Origin checks reject lookalikes; the http.Server has read/write/idle timeouts; the CSP adds frame-ancestors 'none'. --- internal/cli/control.go | 290 ++++++++++++++++++++++++----------- internal/cli/control_test.go | 36 +++++ web/app.js | 36 +++-- web/assets.go | 12 ++ web/index.html | 23 ++- web/styles.css | 9 +- 6 files changed, 297 insertions(+), 109 deletions(-) create mode 100644 internal/cli/control_test.go create mode 100644 web/assets.go diff --git a/internal/cli/control.go b/internal/cli/control.go index 55d0cc1..23cffcd 100644 --- a/internal/cli/control.go +++ b/internal/cli/control.go @@ -12,12 +12,15 @@ import ( "io" "net" "net/http" + "net/url" "os" "os/exec" "path/filepath" "strings" + "time" "github.com/graycodeai/across/internal/store" + acrossweb "github.com/graycodeai/across/web" "github.com/spf13/cobra" ) @@ -25,17 +28,22 @@ func newControlCmd() *cobra.Command { c := &cobra.Command{Use: "control", Short: "Local control plane (org/project/principal/grant)"} c.AddCommand( &cobra.Command{Use: "org-create NAME", Args: cobra.ExactArgs(1), Short: "Create org", RunE: func(cmd *cobra.Command, args []string) error { + if strings.TrimSpace(args[0]) == "" { + return invalidArgument("organization name must not be empty") + } db, _, err := openDB() if err != nil { return err } defer db.Close() id := store.NewID("org") - _, _ = db.Exec(`INSERT INTO organizations(id, name, created_at) VALUES(?,?,?)`, id, args[0], store.NowUTC()) + if _, err := db.Exec(`INSERT INTO organizations(id, name, created_at) VALUES(?,?,?)`, id, args[0], store.NowUTC());

The path the user chooses is now resolved once with EvalSymlinks (ResolveUserPath: deepest existing ancestor resolved, missing components appended), and the rule is applied where it protects something: the directories Across creates and writes inside the home (repositories/, mirrors/, workspaces/, plugins/, backups/, tmp/) must still be real directories. Tests: a home beneath a symlinked ancestor and a symlinked home are accepted and created at the resolved location; a symlinked managed subdirectory is still rejected.

Restore now classifies the target before staging and again at commit: - missing or empty: restored in place; - a non-empty directory without across.db: refused as a conflict (exit 4), even with --force; - an existing Across home: replaced only with the new --force flag, and the previous home is kept as DIR.across-old- (never deleted) and reported. The target's parent is resolved with config.ResolveUserPath, matching how the home itself is resolved. manifest.json is removed from the stage before commit, so it no longer lingers in the restored home. Tests cover a foreign target (with and without --force), an Across home without and with --force (previous home kept, manifest absent), an empty target, a symlinked parent, and a failed snapshot validation that must not displace the target; the E2E round trip exercises the same rules through the binary.

The pre-receive body ends in `exit 0`, so the chain line was unreachable: installing a branch rule on a hosted repository silently disabled the operator's existing pre-receive policy (and the original would not have received the ref updates on stdin even if reached). A chained hook is now generated as a wrapper that runs both parts: - hooks that read stdin (pre-receive, post-receive, pre-push, post-rewrite, reference-transaction, proc-receive) capture stdin to a temp file, run the original first with that input and stop if it rejects, then run the Across body in a subshell with the same input; - other hooks run the Across body in a subshell, then the original, and fail if either fails. Tests: unit tests execute a chained pre-receive (original receives the refs; Across still rejects main; an original rejection propagates) and a chained post-commit (both run, in order); an E2E test pushes to a hosted repo with a pre-existing pre-receive through `branch-rule add`. Both unit tests fail against the previous wrapper.

the confinement check already used the caller's resolved path, but sources.origin and the tombstone lookup still used the staged copy, so provenance pointed at a deleted temp file (/var/folders/.../across-import-XXXX/transcript.jsonl). The import now uses one `origin` (the caller's resolved path, or the file itself for `source import`) for confinement, the tombstone check and the stored origin.

Add unit tests that run them through the command tree: - session fork records parent, fork_type and lineage_version, and rejects a missing parent (3) and a parent from another repository (4); - checkpoint bundle writes a bundle whose bundle_hash reseals to the same value, records the identical payload in evidence_bundles, and returns not_found for an unknown checkpoint; - context pack includes only approved memories, marks over-budget items as not included, rejects a zero budget; context show reproduces the sealed manifest and returns not_found for an unknown id; - handoff --format json reseals to its content_hash, is recorded in handoffs, and rejects an unknown format. The round-trip test found that `context show` of a manifest with no items printed `"items": null` while `context pack` hashed `[]`, so the shown manifest no longer matched its content_hash; show now starts from an empty item list.

SameSite compares sites, not ports, so any page served from another localhost port could send credentialed simple GET/POST requests to the API and to git http-backend after the user had opened the console. A cookie now authorizes a request only when Sec-Fetch-Site is absent, `same-origin` or `none`, and any Origin header equals the served host:port. Bearer-token requests are unchanged, so non-browser clients and git with an Authorization header keep working. Test: table test of requestAuthorized for bearer, same-origin fetch, top-level navigation, non-browser client, matching and mismatched Origin, same-site/cross-site fetch metadata, opaque origin and a wrong cookie.
