Walking skeleton validating the whole echo architecture end to end; the
Command→SQL renderer currently covers `create table`, with the rest of
Bucket A / B / category-3 to follow (ADR-0038 §8).
- Channel (ADR-0037): the three-way EffectiveMode (reusing the existing
enum, not a new SubmissionMode — recorded in the ADR) rides on
Action::ExecuteDsl to the runtime. `replay` bypasses the interactive
spawn, so it never echoes (silent, for free).
- Echo (ADR-0038): built at the runtime's ExecuteDsl dispatch — the worker
gets decomposed calls, not the Command, so ADR §4's "worker builds it"
was corrected to the dispatch layer. Gated by echo_for (advanced
effective mode + DSL-form). Carried on DslSucceeded; rendered by
note_ok_summary as `Executing SQL: …` immediately beneath `[ok]`. New
src/echo.rs renderer; echo.executing_sql i18n key.
- command_to_sql: `create table` → `CREATE TABLE T (id serial PRIMARY KEY)`
(single inline / compound table-level PK), playground type vocabulary,
round-trip-verified against the advanced walker (the §1 contract).
Tests: echo.rs (render, round-trip contract, mode gate, Sql*-not-echoed);
app.rs (submit carries the 3-way mode; echo renders beneath [ok]).
Suite 1970/0/1; clippy clean.
Replay (§3): run_replay parses <ts>|<status>|<source> journal records — runs ok, skips non-ok — while still accepting bare .commands scripts (prefix-detected so a | inside a bare command isn't misread). Fixes replay history.log, which died on line 1.
Journal failures (§1/§2): failed commands are recorded err via a new Action::JournalFailure, emitted by the pure-sync App for both parse failures and worker-execution failures (runtime appends best-effort, never fatal). Hydration reads all records so typo'd/rejected commands are recallable across sessions.
Amendment 1 — replay filters app-lifecycle commands: a working replay history.log exposed that the journal also records save as/load/new/export/import/rebuild/mode (which would panic the worker dispatch or abort replay). Replay now re-applies only schema/data writes and skips every app-lifecycle command + nested replay, classified by entry word so modal/incomplete forms (save as, bare mode) and quit skip uniformly rather than aborting. All skips continue (reversing the nested-replay refusal); import and nested replay warn. replay.error_nested removed; replay.skipped_import/_replay added; ReplayCompleted carries warnings. requirements.md U3/U4 updated; app-command runtime-failure journalling tracked as a follow-up.
1659 passing / 0 failing / 0 skipped / 1 ignored. Clippy clean.
Implements the U4 replay command per handoff §A3:
replay <path>
Reads <path> and dispatches each non-blank, non-`#`-comment
line through the same DSL pipeline as interactive input.
Aborts at the first per-line failure (parse or runtime),
reporting the line number; previously dispatched commands
stay applied (no rollback) — matches the "I'm replaying my
history" mental model where partial replay is a recoverable
state.
Architecture choices and why:
- **Parsed by the DSL parser** (Command::Replay), not as an
app-level command alongside `import` / `export`. The
handoff's implementation sketch was explicit and the
parsed-AST shape gives us a clean test surface for the
path-lexing rules. A new `path_literal` parser terminal
accepts either a single-quoted string (escape rules
mirror `string_literal` — `''` for a literal quote) or a
bare run of non-whitespace, with explicit refusal of `'`,
`(`, `)`, `;` in bare form. Empty paths fail at parse
time so file-system-layer errors aren't shadowed by
silly inputs.
- **Routed away from the worker thread.** Command::Replay
is intercepted in `App::dispatch_dsl` and emitted as
`Action::Replay` rather than `Action::ExecuteDsl`. Two
reasons: (1) the worker has no filesystem context, and
(2) the replay invocation must NOT land in
`history.log` — otherwise `replay history.log` would
re-trigger itself recursively. Only the individual
sub-commands write to history.log via the normal
per-command persistence path.
- **Inner loop separated from spawn.** `runtime::spawn_replay`
is a thin tokio::spawn wrapper around `runtime::run_replay`,
which is `pub` and returns a Vec<AppEvent>. The inner
function is what tests exercise, sidestepping mpsc plumbing.
- **Relative paths resolve under the project root** so
`replay history.log` works without ceremony from inside
any project. Absolute paths pass through unchanged.
- **Nested `replay` is refused.** Allowing `replay foo` from
inside a replay file invites infinite-loop footguns and
opens design questions (transitive composition, ordering)
we'd rather not answer right now. Refusal is explicit.
New plumbing:
- `Command::Replay { path }` AST variant + verb/target_table.
- `Action::Replay { path }` runtime action.
- `AppEvent::ReplayCompleted { path, count }` and
`AppEvent::ReplayFailed { path, line_number, command, error }`.
- `runtime::run_replay` (public) and `runtime::spawn_replay`.
- App handlers render success as
`[ok] replay <path> — N command(s) run` and failures as
`replay <path> failed at line N: <error>` with a
` > <command>` echo line for line context. Line 0 is the
"file open failed" signal — header reads
`replay <path> failed: <error>` and the echo line is
suppressed.
- In-app `help` lists the new command with a continuation
describing comment/blank handling and the relative-path
rule.
Tests (+20):
- 7 parser tests covering bare/quoted/escaped paths,
case-insensitive keyword, and refusal cases (no path,
empty quoted path).
- 9 integration tests in `tests/replay_command.rs`:
- happy 3-line replay → 3 commands run, state mutated;
- blank lines + `#` comments skipped;
- empty file + only-comments file → count 0;
- missing file → ReplayFailed line_number 0;
- parse failure mid-replay → reports correct line +
leaves earlier commands applied + does NOT run later
lines;
- runtime failure mid-replay (refers to nonexistent
table) → reports correct line;
- nested replay refused;
- history.log contains per-command entries but NOT the
`replay …` invocation itself.
- 4 App-level tests: Action::Replay dispatch (not
ExecuteDsl); ReplayCompleted rendering; ReplayFailed
rendering with and without line-number context.
541 -> 561 passing, clippy clean with nursery lints,
release build successful.
A future ADR on the parser-as-source-of-truth direction
(handoff §"Pending §3") would bring richer error reporting
for replay parse failures (currently uses the same
single-line wording as interactive parse failures, which is
adequate but not great when a script has many lines around
the failing one).
Implements the `export` and `import` app-level commands per
ADR-0015 §11 + ADR-0007 amendment 1.
- `export [<path>]` writes a zip of project.yaml + data/ to
<data-root>/YYYYMMDD-<projectname>-export-NN.zip by default,
preserving the project's directory name as the single
top-level folder inside the archive.
- `import <zip> [as <target>]` extracts an exported zip into
a new named project and switches to it. Target name is
derived from the zip's top-level folder by default; on
collision the destination auto-suffixes -02, -03, ... up
to -99 instead of refusing (deviates from §2's refuse-on-
collision rule for save/save as; recorded as an amendment
to ADR-0015 §11).
- Excludes playground.db and history.log from the zip.
- Path-traversal protection via zip::enclosed_name + post-
resolution check that the extraction path stays inside
the target directory.
Adds the zip = "5" dep with default-features = false +
features = ["deflate"] to keep the binary-size cost modest.
Test baseline: 370 passing, 0 failing, 0 skipped.
Adds the rest of the track-2 lifecycle commands (ADR-0015 §11)
and the project-switching machinery they need at runtime.
Temp vs named distinction: replaced the fragile naming heuristic
with an explicit `[temp]` marker in the directory pattern
(`<YYYYMMDD>-[temp]-<word>-<word>-<word>`). validate_user_name
already rejects brackets, so user-typed names can never collide
with a temp marker. The status bar shows `[TEMP] <Display Name>`
for temp projects; the prettifier strips both the date and the
marker so display names are clean.
save / save as: temp project's `save` opens a path-entry modal
(acts as save as); named project's `save` reports "already
auto-saved; use `save as`". `save as` always prompts. Relative
names resolve under <data-root>/projects/; absolute paths used
as-is. Copy excludes the per-process lock file; everything else
(.db, yaml, csvs, history.log) is copied.
new: closes current project, creates a fresh auto-named temp,
switches.
load: opens a picker. List sub-mode shows projects in the active
data root, sorted newest-first by project.yaml mtime; arrow keys
navigate, Enter loads, `b` switches to a path-entry sub-mode for
projects elsewhere, Esc cancels. Empty data root jumps straight
to path entry.
Runtime: `Session` holds Option<Project> + Option<Database> so
project switches can drop old (releasing lock + stopping worker)
before opening new -- required for the "load my own current
project" case. `perform_switch` handles Load / SaveAs / NewTemp
uniformly.
Tests: 332 passing (270 lib + 9 + 5 + 6 + 16 new + 9 + 17),
0 failing, 0 skipped. Clippy clean.
Adds the explicit `rebuild` app-level command (ADR-0015 §7, §11)
and a modal UI infrastructure to host its confirmation dialog.
Typing `rebuild` emits Action::PrepareRebuild; the runtime reads
project.yaml + data/ to compute a summary ("3 tables and 47 rows
will be reconstructed; the existing playground.db will be
replaced") and posts AppEvent::RebuildPrepared, which opens the
modal. Y confirms, N/Esc cancels. While the modal is open,
normal input is gated.
The worker's do_rebuild_from_text now wipes existing user tables
and metadata before reloading from text, so it works on both
fresh and populated databases. Source text is plumbed through
rebuild_from_text so the explicit rebuild logs to history.log
while the silent on-load rebuild from Iteration 3 stays silent.
Modal infrastructure (App.modal field + key routing + centered
overlay rendering + word-wrap) is reused by Iteration 4b's save
/ save as / load / new flows.
Tests: 314 passing (268 lib + 9 + 5 + 6 new + 9 + 17),
0 failing, 0 skipped. Clippy clean.
Every successful user command now persists through to YAML, the
affected CSVs, and history.log inside the same SQLite transaction,
with the commit-db-last ordering from ADR-0015 §6: validate ->
mutate -> stage text + fsync -> atomic rename -> append history ->
commit. A failure in any text-write step rolls back the SQLite tx,
so disk state is unchanged on failure. Persistence failures are
routed through a new AppEvent::PersistenceFatal which sets a
fatal_message on the App, emits Action::Quit, and is printed to
stderr after terminal teardown so the banner remains above the
shell prompt (ADR-0015 §8).
New persistence module owns the file formats: hand-rolled YAML
schema writer, per-type CSV encoder (RFC 4180, NULL distinct from
empty string, base64 blobs), append-only history.log with ISO-8601
timestamps and successful-only entries. Atomic per-file writes via
tmp + fsync + rename.
The db worker holds an Option<Persistence>; tests still use
Database::open(":memory:") with no persistence. Action::ExecuteDsl
gains a source field carrying the user-typed text, threaded
through to history.log.
Tests: 289 passing (256 lib + 7 new integration + 9 lifecycle + 17
walking-skeleton), 0 failing, 0 skipped. Clippy clean with nursery
lints.
First implementation milestone: Cargo project, dependencies,
and a minimal but functional TUI shell built on Ratatui +
Crossterm + Tokio in the Elm-style update/view pattern
(Candidate A from Phase 2/3 selection).
Includes:
- Three-region layout: items list (left), output + input + hint
(right), bottom status bar with mode-aware shortcuts.
- Two themes (light, dark) plus COLORFGBG auto-detect, per
NFR-7. CLI: --theme {light,dark}, --log-file <path>.
- Input modes per ADR-0003: simple (default), advanced, with
the `:` one-shot escape including immediate prompt reaction
("Advanced:" label, advanced border) and auto-inserted space
after a leading `:` in simple mode.
- App-level commands: `quit`/`q`, `mode simple`/`mode advanced`
(canonical list per ADR-0003 — remaining commands land in
later iterations).
- File logging via tracing, defaulting to ~/.rdbms-playground/
playground.log so the TUI is not corrupted by stdio.
Testing per ADR-0008:
- Tier 1: 29 unit tests covering input handling, mode switch,
one-shot escape, auto-space, output buffering, CLI parsing.
- Tier 2: 4 insta snapshots (default simple/advanced/light,
one-shot active) of TestBackend frames.
- Tier 3: 7 integration tests driving synthetic events through
App::update + render path.
All green: 36 tests, 0 failures, 0 skips. Clippy clean with
nursery lints enabled.
