Completes the i18n sweep started in the previous commit. All
remaining hand-rolled user-facing English strings inside
thiserror #[error(...)] attributes have been moved into the
catalog. Drops the thiserror dependency entirely.
Twelve error types migrated:
- dsl::action::UnknownAction → parse.custom.unknown_action
- dsl::parser::ParseError → parse.error_wrapper + parse.empty
- dsl::value::ValueError → value.{type_mismatch,format}
- persistence::csv_io::CsvError → persistence.csv.*
- persistence::mod::PersistenceError → persistence.{io,encode}
- persistence::yaml::YamlError → persistence.yaml.*
- persistence::migrations::MigrateError → persistence.migrate.*
- project::lock::LockError → project.lock.*
- project::naming::NamingError → project.naming.*
- project::naming::UserNameError → project.user_name.*
- project::mod::ProjectError → project.{path_not_found,...}
- project::mod::SafeDeleteError → project.safe_delete.*
- archive::ArchiveError → archive.*
- cli::ArgsError → cli.*
- db::DbError → db.error.*
Pattern per type: drop thiserror::Error derive, write manual
Display calling crate::t!(), keep #[from] semantics via
explicit From impls, override Error::source() where applicable
so #[source]-style chaining is preserved.
Why this matters (user rationale): "fine to have fallbacks for
errors that are purely technical, but lift the output to a
place where it can be localized later and where an adjustment
with friendly text is easily possible if any of them become
part of the happy path." All surface strings now live in
en-US.yaml and can be reworded or localized without touching
Rust source.
Tests: 769 passing, 0 failed, 1 ignored. Clippy clean with
-D warnings. Cargo.toml: drop thiserror = "2.0.18".
Generalises serial and shortid beyond their previous restricted
forms:
- `serial` is no longer restricted to single-column PK. Non-PK
serial columns get an emitted UNIQUE constraint and use
application-side MAX(col)+1 at INSERT time (rowid alias still
drives the PK case for free; per ADR-0010 worker-thread
serialisation, the read-then-insert sequence is safe).
- `shortid` columns auto-fill existing null cells when the
column is materialised — `add column T: x (shortid)` on a
non-empty table no longer leaves rows in a not-really-valid
NULL state.
- `int -> serial` joins the type-change matrix as always-clean
identity (closes the asymmetry vs `text -> shortid`); other
sources are refused with a route-via-int hint.
- `change column T: x (serial|shortid)` fills null source
cells with sequence / generated values in the same rebuild
transaction.
Internal infrastructure:
- ReadColumn gains `unique: bool`; read_schema detects single-
column UNIQUE indexes via pragma_index_list /
pragma_index_info; schema_to_ddl emits inline UNIQUE for
non-PK columns.
- ColumnSchema (persistence) gains `unique: bool` so the flag
survives YAML round-trip and rebuild-from-text reconstructs
it faithfully — preserves the "serial -> int leaves UNIQUE
in place" promise across save/load cycles.
- ChangeColumnTypeResult.client_side now carries `auto_filled`
+ `auto_fill_kind` alongside `transformed` + `lossy`; the
app handler renders separate note lines when both apply.
- AddColumnResult is a new return type carrying pre-rendered
[client-side] note lines for the auto-fill paths.
Tests: 519 -> 534 (+15). Clippy clean.
When the runtime opens a project whose playground.db is missing,
it now rebuilds the database from project.yaml + data/<table>.csv
per ADR-0015 §7. The rebuild path:
1. Parses project.yaml (serde_yml). Unknown versions / types /
actions surface as PersistenceFatal.
2. Recreates each user table with FK constraints inline
(PRAGMA foreign_keys=OFF), then populates the column-type,
relationship, and project metadata tables.
3. Loads each table's CSV via a hand-rolled reader that
preserves the NULL-vs-empty distinction (the csv crate
doesn't expose whether a field was quoted; ours does).
4. Runs PRAGMA foreign_key_check before commit; any violation
aborts.
5. Restores foreign_keys=ON regardless of success.
Row-level failures get DbError::RebuildRowFailed with row
number, file, table, and a friendly per-type detail. They land
in the runtime as a fatal stderr message ("unable to load row N
from `data/T.csv` into table `T`: ...") before the alternate
screen is entered.
created_at from project.yaml overwrites the configure-time
placeholder so timestamps round-trip stably.
Tests: 307 passing (267 lib + 9 + 5 new + 9 + 17), 0 failing,
0 skipped. Clippy clean with nursery lints.
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.
