Adds + `--migration-id ` (override timestamp prefix) and `--dryrun` (print plan + without writing artifacts), matching the TS flag set verbatim. +- **`chkit migrate`** defaults to **plan/preview** like TS. Use `--apply` (or + alias `--execute`) to actually run statements. Added `--allow-destructive` + for migrations whose plan contains `risk=danger` operations (exit code 3 + when blocked, mirroring TS). +- **ClickHouse-backed journal**: applied migrations are recorded in a + `_chkit_migrations` table in the target database, schema identical to + `packages/cli/src/runtime/journal-store.ts` + (`ReplacingMergeTree(applied_at) ORDER BY (name)`). Both TS and Python now + share the same journal table.

Only meaningful once plugins exist in Python. | + +### Command flags missing in Python + +| Command | Flag | Why deferred | +|---|---|---| +| `generate` | `--rename-table`, `--rename-column` | Explicit rename mappings + the `plan-pipeline.ts` / `rename-mappings.ts` machinery (~600 lines).

The +Python port currently does only the snapshot-vs-current-schema diff, which is +the in-CI use case. The live-DB introspection is the bigger lift since it +requires re-implementing the TS DDL parser. + +### Journal store + +| TS feature | Status | Why deferred | +|---|---|---| +| Per-operation async tracking (`operations` tuple, `migration_completed=false` for in-flight) | Not used | The Python `migrate` runs synchronously: every statement either succeeds or the migration errors out before the entry is journaled. The columns exist in the table so the schemas match, but Python always inserts `migration_completed=true` and `operations=[]`. | +| Insert race retries (`INSERT race condition` detection) | Not modelled | Race only matters with concurrent appliers; first-base assumes a single applier per project. | + +### Config loader + +| TS feature | Status | Why deferred | +|---|---|---| +| Async config functions (`(env) => config` or `(env) => Promise`) | Not supported in Python (synchronous only) | Python `clickhouse.config.py` is imported and the `config` attribute is read. Async configs would need a `_resolve_config()` indirection. | +| User profile config (`~/.config/chkit/profile.config.ts`) and credentials layer | Not ported | Allows running `chkit` from outside a project against the ObsessionDB profile. Out of scope for self-hosted ClickHouse users. | +| `chkit obsessiondb login` synthesized profile fallback | Not ported | Coupled to the missing `@chkit/plugin-obsessiondb`. | + +### Misc + +| TS surface | Status | Why deferred | +|---|---|---| +| `safety-markers.ts` (per-statement risk overrides via SQL comments) | Not ported | Generate already emits risk per op in headers; the override mechanism isn't yet used by core commands. | +| `debug.ts` structured debug logging | Not ported | Python uses Typer's normal stderr; `--json` output handles machine-readable mode. | + +## Adding parity for a deferred item + +1. Find the TS source file in `packages/cli/src/...` or `packages/plugin-*/src/...`. +2. Port the helper functions / data classes into the equivalent + `src/chkit/cli/...` or a new `src/chkit/plugin_*` module. +3. Add a parity test under `tests/test_*_parity.py` that mirrors the TS + `*.test.ts` if one exists, or write a new test that asserts the observable + behaviour matches the TS docs / source comments. +4. Update this matrix: move the row from "Deferred" to "1:1 with TS (Done)". +5.

structured --json envelopes, never a bare string MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Under --json, whoami/logout/login/service-list/service-select printed a JSON-encoded *string* (e.g. "Not logged in…") instead of an object: the serializer JSON.stringify'd whatever it received, and those commands never threaded jsonMode, so they passed plain strings. This broke the documented agent contract — piping their --json output to jq failed because a bare string isn't the {status,next}/{ok,error} envelope callers expect. Fix in two deliberate layers: - A catch-all in printOutput wraps any string in {schemaVersion, message} while in --json mode. This closes the whole class of bug at its single chokepoint, so no command can ever emit a bare string again — even ones we don't special-case. - Purpose-built envelopes for the two commands agents actually consume: whoami (logged_in / not_logged_in / session_expired) and service list (one object with a services[] array, instead of one JSON line per service, which isn't valid single-JSON). login/logout/alias are intentionally left to the catch-all: they aren't part of the documented machine flow, so a dedicated envelope each would be disproportionate plumbing for no chaining benefit. BREAKING: whoami and service-list --json output changes shape from string to object. This is the intended fix to the JSON contract. --- packages/cli/src/runtime/json-output.ts | 9 ++++- .../plugin-obsessiondb/src/auth/commands.ts | 2 +- packages/plugin-obsessiondb/src/auth/login.ts | 27 +++++++++++--- .../src/json-envelope.test.ts | 27 ++++++++++++++ .../plugin-obsessiondb/src/json-envelope.ts | 36 +++++++++++++++++++ .../src/service/commands.ts | 31 ++++++++++++++-- 6 files changed, 123 insertions(+), 9 deletions(-) diff --git a/packages/cli/src/runtime/json-output.ts b/packages/cli/src/runtime/json-output.ts index d22e7da8..521daecf 100644 --- a/packages/cli/src/runtime/json-output.ts +++ b/packages/cli/src/runtime/json-output.ts @@ -19,7 +19,14 @@ export function hasEmittedJson(): boolean { export function printOutput(value: unknown, jsonMode: boolean): void { if (jsonMode) { jsonEmitted = true - console.log(JSON.stringify(value, null, 2)) + // Catch-all: never emit a bare JSON string.

It discarded the executor the host already resolves and hands to every command — so pull could not introspect an ObsessionDB instance at all, and the "using service" line was misleading. Route pull through pluginContext.executor, the same executor that generate/migrate/status use. The host resolves it per command (the ObsessionDB remote executor when a service is selected, a direct ClickHouse executor otherwise), and the remote executor already implements exactly the methods pull needs (listSchemaObjects, listTableDetails, query). We only build a client from config.clickhouse when the host provides no executor. Chosen over "just fail clearly on an ObsessionDB target" because routing makes pull actually work against ObsessionDB — the headline onboarding target — rather than failing more politely. Custom introspectors still open their own raw-ClickHouse connection (and require the config block), and the genuine no-target case now errors with an actionable message instead of a silent localhost fallback. --- packages/plugin-pull/src/index.ts | 52 +++++++++++++++++++++---------- 1 file changed, 35 insertions(+), 17 deletions(-) diff --git a/packages/plugin-pull/src/index.ts b/packages/plugin-pull/src/index.ts index 709231aa..f2e91f2b 100644 --- a/packages/plugin-pull/src/index.ts +++ b/packages/plugin-pull/src/index.ts @@ -4,6 +4,7 @@ import { dirname, join, resolve } from 'node:path' import { z } from 'zod' import { + type ClickHouseExecutor, createClickHouseExecutor, type IntrospectedTable, } from '@chkit/clickhouse' @@ -60,6 +61,8 @@ export interface PullPluginCommandContext { config: ResolvedChxConfig configPath: string print: (value: unknown) => void + /** Executor resolved by the host (e.g. the ObsessionDB remote executor when a service is selected). */ + pluginContext?: { executor: ClickHouseExecutor; hasExecutor: boolean } } export interface PullPlugin { @@ -169,7 +172,7 @@ export function createPullPlugin(options: PullPluginOptions = {}): PullPlugin { flags: PULL_SCHEMA_FLAGS, optionsSchema, flagMapping: PULL_FLAG_MAP, - async run({ flags, jsonMode, print, options: opts, config }) { + async run({ flags, jsonMode, print, options: opts, config, pluginContext }) { return wrapPluginRun({ command: 'schema', label: 'Pull schema', @@ -194,6 +197,7 @@ export function createPullPlugin(options: PullPluginOptions = {}): PullPlugin { const dryrun = flags['--dryrun'] === true const pulled = await pullSchema({ config, + executor: pluginContext?.hasExecutor ? pluginContext.executor : null, options: { ...effectiveOptions, introspect: introspector }, }) @@ -254,30 +258,45 @@ export function pull(options: PullPluginOptions = {}): PullPluginRegistration { async function pullSchema(input: { config: ResolvedChxConfig + executor?: ClickHouseExecutor | null options: PullOptions & { introspect?: PullIntrospector } }): Promise { - if (!input.config.clickhouse) { - throw new PullConfigError('clickhouse config is required for pull plugin') + const customIntrospector = input.options.introspect + + // Prefer the host-provided executor — e.g. the ObsessionDB remote executor when a service is + // selected — so pull introspects through whatever target the rest of the CLI targets, not just a + // direct ClickHouse URL.

The poll call had no error handling, so a single HTTP 524 (gateway timeout) on a *poll request* threw out of the loop and aborted the migration — even though the server-side INSERT kept running (we observed ~34.8M of 100M rows land after chkit had given up). A poll request timing out was wrongly conflated with the load itself failing. Wrap the poll in try/catch and treat a transient poll error as "keep polling", up to a bounded budget (MAX_TRANSIENT_POLL_ERRORS). Only a real ExceptionWhileProcessing status, or a submit-time rejection, is fatal. When the budget is exhausted we stop with an explicit message that the load may still be running and that re-running re-attaches via the deterministic query_id — never a silent abort and never an infinite loop. A bounded budget (rather than infinite tolerance) is deliberate: a genuinely dead endpoint must not hang forever, while normal gateway blips on a multi-minute load are absorbed.

Users (and our own tutorial) naturally reached for `chkit skills add …`, which returned "Unknown command: skills". Add a thin `chkit skills` command that forwards its arguments to the external `skills` CLI (`npx skills `) and passes through its exit code. It is intercepted early in dispatch, like `init`, because it needs no project config or executor. A proxy is chosen over a docs-only fix because it removes the foot-gun entirely — `chkit skills add …` now does the expected thing — while keeping `skills` as the real underlying tool.

12:30:09 +0200 Subject: [PATCH 15/47] feat(core): expand public exports + audit fixes (primary_key fallback, dependsOn camelCase) Exports added to chkit.core for the public surface used by plugin authors: key_clause helpers (split_top_level_comma, normalize_key_columns), SQL splitter helpers (split_sql_statements, extract_executable_statements), SQL normalizers (normalize_sql_fragment, normalize_engine). These were present internally but never re-exported. canonical.py: - canonicalize_definition now backfills empty primary_key from order_by, matching TS canonical.ts. Without this a snapshot written by the TS CLI (where the user omits primaryKey and TS substitutes orderBy) would appear to drift against a Python-written snapshot of the same schema. - _canonicalize_refresh emits the camelCase 'dependsOn' key (with by_alias=True on the inner TableRef dump) so cross-port snapshot JSON matches byte-for-byte. --- chkit_python/src/chkit/core/__init__.py | 31 ++++++++++++++++++++++++ chkit_python/src/chkit/core/canonical.py | 20 ++++++++++++--- chkit_python/src/chkit/core/model.py | 2 ++ 3 files changed, 50 insertions(+), 3 deletions(-) diff --git a/chkit_python/src/chkit/core/__init__.py b/chkit_python/src/chkit/core/__init__.py index 67a26d59..e1d3861a 100644 --- a/chkit_python/src/chkit/core/__init__.py +++ b/chkit_python/src/chkit/core/__init__.py @@ -15,6 +15,10 @@ parse_codec, render_codec, ) +from chkit.core.config_path import ( + SYNTHESIZED_CONFIG_PATH, + is_synthesized_config_path, +) from chkit.core.flags import ( FlagDef, MissingFlagValueError, @@ -23,6 +27,7 @@ define_flags, parse_flags, ) +from chkit.core.key_clause import normalize_key_columns, split_top_level_comma from chkit.core.model import ( ChxResolvedClickHouseConfig, ChxResolvedConfig, @@ -62,11 +67,25 @@ view, ) from chkit.core.planner import plan_diff +from chkit.core.plugin_error import wrap_plugin_run +from chkit.core.schema_loader import ( + NO_MATCH_MESSAGE, + SchemaLoaderError, + load_schema_definitions, +) from chkit.core.snapshot import create_snapshot from chkit.core.sql import to_create_sql +from chkit.core.sql_normalizer import normalize_engine, normalize_sql_fragment +from chkit.core.sql_splitter import ( + extract_executable_statements, + split_sql_statements, +) +from chkit.core.ts_import import ModuleLoadError, import_module_file from chkit.core.validate import assert_valid_definitions, validate_definitions __all__ = [ + "NO_MATCH_MESSAGE", + "SYNTHESIZED_CONFIG_PATH", "ChxResolvedClickHouseConfig", "ChxResolvedConfig", "ChxUserClickHouseConfig", @@ -83,6 +102,7 @@ "MigrationOperationType", "MigrationPlan", "MissingFlagValueError", + "ModuleLoadError", "ParsedFlags", "PreprocessingColumnCodec", "PrimitiveColumnType", @@ -90,6 +110,7 @@ "RawColumnCodec", "RiskLevel", "SchemaDefinition", + "SchemaLoaderError", "SkipIndexDefinition", "Snapshot", "SnapshotV1", @@ -110,19 +131,29 @@ "define_config", "define_flags", "definition_key", + "extract_executable_statements", + "import_module_file", "is_general_codec", "is_preprocessor_codec", "is_raw_codec", "is_schema_definition", + "is_synthesized_config_path", + "load_schema_definitions", "materialized_view", + "normalize_engine", + "normalize_key_columns", + "normalize_sql_fragment", "parse_codec", "parse_flags", "plan_diff", "render_codec", "resolve_config", "schema", + "split_sql_statements", + "split_top_level_comma", "table", "to_create_sql", "validate_definitions", "view", + "wrap_plugin_run", ] diff --git a/chkit_python/src/chkit/core/canonical.py b/chkit_python/src/chkit/core/canonical.py index 0e6de986..7c3c1a5b 100644 --- a/chkit_python/src/chkit/core/canonical.py +++ b/chkit_python/src/chkit/core/canonical.py @@ -94,6 +94,13 @@ def _canonicalize_table(definition: TableDefinition) -> TableDefinition: name=definition.renamed_from.name.strip(), ) + normalized_order_by = normalize_key_columns(definition.order_by) + normalized_primary_key = normalize_key_columns(definition.primary_key) + # TS canonical.ts: when primary_key is empty, fall back to order_by. + # Without this, a snapshot written by TS (where omitted PK == order_by) + # would never match a Python snapshot (where omitted PK == []). + if not normalized_primary_key: + normalized_primary_key = list(normalized_order_by) return definition.model_copy( update={ "database": definition.database.strip(), @@ -101,8 +108,8 @@ def _canonicalize_table(definition: TableDefinition) -> TableDefinition: "renamed_from": renamed_from, "engine": normalize_engine(definition.engine), "columns": [_canonicalize_column(c) for c in definition.columns], - "primary_key": normalize_key_columns(definition.primary_key), - "order_by": normalize_key_columns(definition.order_by), + "primary_key": normalized_primary_key, + "order_by": normalized_order_by, "unique_key": normalize_key_columns(definition.unique_key) if definition.unique_key is not None else None, @@ -181,7 +188,14 @@ def _canonicalize_refresh( if randomize is not None: payload["randomize"] = randomize if depends_on is not None and len(depends_on) > 0: - payload["depends_on"] = [d.model_dump() for d in depends_on] + # Use the camelCase alias key for the canonical dict so callers that + # compare the raw dict to a TS-emitted snapshot see matching keys. + # ``model_validate`` accepts both forms thanks to + # ``populate_by_name=True``;

plugin surface mirroring TS packages/cli/src/plugins.ts: Manifests + plugin: - ChxPluginManifest / ChxPluginManifestCompatibility / Cli - ChxPlugin (manifest + hooks + commands + options_schema + extend_commands) - LoadedPlugin (validated + options resolved) Hook contexts (10): - ChxOnInitContext, ChxOnCompleteContext - ChxOnConfigLoadedContext, ChxOnSchemaLoadedContext, ChxOnPlanCreatedContext - ChxOnBeforeApplyContext, ChxOnAfterApplyContext - ChxOnCheckContext, ChxOnCheckResult, ChxOnCheckReportContext, ChxCheckFinding - ChxOnBeforePluginCommandContext + ChxOnBeforePluginCommandHandled / Unhandled / Result (used by obsessiondb to route backfill status/cancel/ list through its jobs API before the local backfill plugin's stubs run). - ChxOnPullIntrospectContext: lets plugins inject SchemaDefinition lists, bypassing the SQL-based pull (obsessiondb metadata API use case). Commands + context: - ChxPluginCommand (name + run + description + flags) - ChxPluginCommandContext (config + flags + options + table_scope + plugin_runtime + plugin_context). - PluginContext (executor + has_executor) + ChxGetContextInput for the getContext hook (plugins return a custom executor; the obsessiondb plugin's remote executor uses this when a service is selected).

(KNOWN_KEYS set so unknown markers raise instead of being silently ignored). journal_store.py: the _chkit_migrations ClickHouse table abstraction. Stores migration name + applied_at + checksum + chkit_version + per-statement OperationState (query_id + status + timestamps + last_error) for async-apply resume support. UNKNOWN_DATABASE detection so status/drift gracefully report database-missing without crashing. json_output.py + logging_setup.py: small plumbing for --json envelope formatting and CHKIT_DEBUG=1 stdlib-logging configuration. main.py: Typer app wiring + register every core command. schema_loader.py: thin wrapper of chkit.core.schema_loader so CLI commands don't need to import the core sub-module directly. --- chkit_python/src/chkit/cli/journal_store.py | 193 +++++++- chkit_python/src/chkit/cli/json_output.py | 99 ++++ chkit_python/src/chkit/cli/logging_setup.py | 58 +++

Documented in DRIFT.md > init/auto-deps. Tests cover every flag combination, the silent mode, the runbook output shape when the plugin is absent, and the OBSESSIONDB_PLUGIN_MODULE monkeypatch hook used by the cross-cutting test isolation. --- .../src/chkit/cli/commands/__init__.py | 24 +- chkit_python/src/chkit/cli/commands/init.py | 159 +++++++++-- chkit_python/tests/test_init.py | 270 ++++++++++++++++++ 3 files changed, 429 insertions(+), 24 deletions(-) create mode 100644 chkit_python/tests/test_init.py diff --git a/chkit_python/src/chkit/cli/commands/__init__.py b/chkit_python/src/chkit/cli/commands/__init__.py index 78e3da17..27e2c736 100644 --- a/chkit_python/src/chkit/cli/commands/__init__.py +++ b/chkit_python/src/chkit/cli/commands/__init__.py @@ -1,5 +1,25 @@ """chkit CLI commands.""" -from chkit.cli.commands import check, drift, generate, init, migrate, status +from chkit.cli.commands import ( + check, + drift, + generate, + init, + migrate, + plugin, + pull, + query, + status, +) -__all__ = ["check", "drift", "generate", "init", "migrate", "status"] +__all__ = [ + "check", + "drift", + "generate", + "init", + "migrate", + "plugin", + "pull", + "query", + "status", +] diff --git a/chkit_python/src/chkit/cli/commands/init.py b/chkit_python/src/chkit/cli/commands/init.py index ac272c74..6805d274 100644 --- a/chkit_python/src/chkit/cli/commands/init.py +++ b/chkit_python/src/chkit/cli/commands/init.py @@ -1,19 +1,51 @@ """`chkit init` — scaffold a starter project. -1:1 port of ``packages/cli/src/commands/init.ts``.

Flags mirror TS exactly (--name / --migration-id / --rename-table / --rename-column / --dryrun / --json / --config / --table). plan-pipeline (generate_plan_pipeline.py): - apply_explicit_table_renames: rewrites drop+create pairs as rename ops. - apply_selected_rename_suggestions: collapses drop+create column pairs. - build_explicit_column_rename_suggestions: turn CLI mappings into suggestions for the renamer. - assert_cli_column_mappings_resolvable: error if a CLI --rename-column references a column not in the diff. rename-mappings (generate_rename_mappings.py): parse_rename_*_mappings, merge_*_mappings + conflict assertions, collect_schema_rename_mappings, resolve_active_table_mappings, remap_old_definitions_for_table_renames. Cross-DB renames emit CREATE DATABASE IF NOT EXISTS at the right ordering rank. Codegen integration: after writing the migration, if a 'codegen' plugin is registered with run_on_generate != False, dispatch its codegen command. Factory-supplied options are read from the plugin's hook closure (a PluginConfig instance under .options) since load_plugin_runtime today doesn't thread factory options through LoadedPlugin.options. plan_diff is wrapped in try/except ChxValidationError — under --json the error surfaces as {error: 'validation_failed', issues: [...]} instead of a raw stack trace. scope is now included in every JSON output path (apply / empty-plan / dryrun). --- .../src/chkit/cli/commands/generate.py | 335 ++++++++++++++- .../cli/commands/generate_plan_pipeline.py | 265 ++++++++++++ .../cli/commands/generate_rename_mappings.py | 360 ++++++++++++++++ .../tests/test_codegen_integration_e2e.py | 112 +++++ .../tests/test_generate_plan_pipeline.py | 297 +++++++++++++ .../tests/test_generate_rename_mappings.py | 390 ++++++++++++++++++ .../tests/test_generate_renames_e2e.py | 253 ++++++++++++ 7 files changed, 2002 insertions(+), 10 deletions(-) create mode 100644 chkit_python/src/chkit/cli/commands/generate_plan_pipeline.py create mode 100644 chkit_python/src/chkit/cli/commands/generate_rename_mappings.py create mode 100644 chkit_python/tests/test_codegen_integration_e2e.py create mode 100644 chkit_python/tests/test_generate_plan_pipeline.py create mode 100644 chkit_python/tests/test_generate_rename_mappings.py create mode 100644 chkit_python/tests/test_generate_renames_e2e.py diff --git a/chkit_python/src/chkit/cli/commands/generate.py b/chkit_python/src/chkit/cli/commands/generate.py index 49c1e9cb..0f1eb844 100644 --- a/chkit_python/src/chkit/cli/commands/generate.py +++ b/chkit_python/src/chkit/cli/commands/generate.py @@ -2,11 +2,13 @@ Flag set matches the TypeScript ``generateCommand``: -- ``--name`` Migration name (sanitized via ``safe_name``; default "auto"). -- ``--migration-id``Override the timestamp prefix in the migration filename. -- ``--dryrun`` Print the plan without writing artifacts. -- ``--json`` Emit a JSON-formatted summary instead of human text. -- ``--config`` Path to the config file (default ``clickhouse.config.py``). +- ``--name`` Migration name (sanitized via ``safe_name``; default "auto"). +- ``--migration-id`` Override the timestamp prefix in the migration filename. +- ``--rename-table`` Explicit table rename (``old_db.old_t=new_db.new_t``); repeatable. +- ``--rename-column`` Explicit column rename (``db.t.old=new``); repeatable. +- ``--dryrun`` Print the plan without writing artifacts. +- ``--json`` Emit a JSON-formatted summary instead of human text. +- ``--config`` Path to the config file (default ``clickhouse.config.py``).

command + async-apply engine + prompts + plugin hooks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit migrate.py: --apply / --execute (alias) / --dryrun / --table / --json / --config / --allow-destructive. Default behaviour is plan/preview. Apply loop: - Reads each pending file → runs run_on_before_apply (plugins may transform the statement list) → executes each statement, dispatching to async-apply for operations marked mode=async in their -- operation: header → writes journal entry → runs run_on_after_apply. - wait_for_ddl_propagation after each statement (operation-type-aware). migrate_async_apply.py: deterministic query_id = chkit-{migration_checksum}- {statement_index}.

chkit status + chkit drift commands MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit status.py: lists migration files, intersects with the _chkit_migrations journal applied set (project-scoped — only counts THIS project's migrations even when the journal table is shared across tenants). Honors --table, --json, gracefully handles UNKNOWN_DATABASE (returns {databaseMissing: true, database: ...} in JSON). drift.py + drift_payload.py + drift_compare.py + drift_diff.py: - build_drift_payload joins snapshot definitions against live introspection (lists schema objects → fetch table details for any database appearing in the snapshot). - compare_schema_objects + compare_table_shape: per-kind + per-column + per-engine-arg + per-setting + per-skip-index + per-projection diff. - summarize_drift_reasons: counts split into object-level vs table-level. - --live flag (Python-only) opens a connection for full payload; default is snapshot-only fast-path. Honors --table for partial scope. Tests cover the drift_compare permutations. --- chkit_python/src/chkit/cli/commands/drift.py | 101 ++++- .../src/chkit/cli/commands/drift_compare.py | 398 ++++++++++++++++++ .../src/chkit/cli/commands/drift_diff.py | 68 +++ .../src/chkit/cli/commands/drift_payload.py | 186 ++++++++ chkit_python/src/chkit/cli/commands/status.py | 46 +- chkit_python/tests/test_drift_compare.py | 267 ++++++++++++ 6 files changed, 1060 insertions(+), 6 deletions(-) create mode 100644 chkit_python/src/chkit/cli/commands/drift_compare.py create mode 100644 chkit_python/src/chkit/cli/commands/drift_diff.py create mode 100644 chkit_python/src/chkit/cli/commands/drift_payload.py create mode 100644 chkit_python/tests/test_drift_compare.py diff --git a/chkit_python/src/chkit/cli/commands/drift.py b/chkit_python/src/chkit/cli/commands/drift.py index a16c5959..4fae2d5e 100644 --- a/chkit_python/src/chkit/cli/commands/drift.py +++ b/chkit_python/src/chkit/cli/commands/drift.py @@ -24,19 +24,27 @@ from __future__ import annotations import json +from dataclasses import asdict from pathlib import Path from typing import Annotated import typer +from chkit.cli.commands.drift_payload import build_drift_payload from chkit.cli.config_loader import load_config from chkit.cli.migration_store import read_snapshot from chkit.cli.schema_loader import load_schema +from chkit.cli.table_scope import ( + filter_plan_by_table_scope, + resolve_table_scope, + table_keys_from_definitions, +) +from chkit.clickhouse.client import ClickHouseClient from chkit.core.canonical import canonicalize_definitions from chkit.core.planner import plan_diff -def run( +def run( # noqa: PLR0912, PLR0915 config_path: Annotated[ Path | None, typer.Option("--config", "-c", help="Path to clickhouse.config.py."), @@ -44,6 +52,24 @@ def run( output_json: Annotated[ bool, typer.Option("--json", help="Emit a JSON-formatted summary.") ] = False, + table_selector: Annotated[ + str | None, + typer.Option( + "--table", + "-t", + help="Scope drift detection to tables matching the selector.", + ), + ] = None, + live: Annotated[ + bool, + typer.Option( + "--live", + help=( + "Compare snapshot against live ClickHouse instead of the local " + "schema.

29 Jun 2026 12:32:51 +0200 Subject: [PATCH 25/47] feat(cli/query): chkit query command (ad-hoc SQL with text-table + JSON output) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Single positional SQL arg (rejects multi-arg + empty). --json, --config. Text-table output: column width auto-sizing, header + separator, DEFAULT_SHOWN_ROW_LIMIT=25 with truncation indicator. JSON envelope = ClickHouseJsonQueryResult shape: data[] + meta[] (per column name + type) + rows + statistics + query_id. Matches TS exactly for downstream consumers. Error cleaning: strip the injected 'FORMAT JSON' artifact, truncate 'Expected one of [...]' lists past EXPECTED_TOKEN_CAP=8 tokens. Mirrors TS error-cleaner behaviour 1:1.

12:33:38 +0200 Subject: [PATCH 28/47] feat(plugin-obsessiondb): full ObsessionDB plugin (foundation + auth + services + remote/backfill/onboarding) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1 — foundation: - credentials.py: XDG-compliant 0600 ~/.config/chkit/credentials.json, resolve_base_url honors OBSESSIONDB_API_URL env override. - storage.py: SelectedService (only service_slug + service_name required — the other org/service-id fields are optional Python additions, kept None by default so a TS-written .chkit/obsessiondb.json deserializes here). Project + user-global service-state files + alias map. - engine.py: on_schema_loaded hook rewrites Shared* engines to standard ClickHouse equivalents when targeting a non-obsessiondb host. Strips cloud-only settings (storage_policy). --force-shared-engines / --no-shared-engines overrides; auto-detect from URL. - plugin.py: obsessiondb() factory + ChxPluginManifest + hooks + 5 commands (login / logout / whoami / signup / service). Phase 2 — auth flows: - api_client.py: RFC 8628 device-code (request + poll + slow_down + expired_token), get_session, passwordless OTP (send + verify), org create + set_active. SessionExpiredError on 401 surfaces from the service_api/jobs_api/workbench_api layer; OtpRateLimitError on 429. - auth_login.py: device-code flow + browser open + poll loop. - auth_signup.py: 3 modes (interactive TTY, two-step CI via --request-only then --code, scripted via --email + --code). Auto-create personal org (derive_org_name strips +subaddress, slugify_org_name appends 6-char random suffix). - run_logout / run_whoami (with --json envelope). Phase 3 — services: - service_api.py: oRPC client (POST /rpc/{procedure_path} with {input: ...} body, bearer auth). HTTP 401 → SessionExpiredError. - service_select.py: render_service_organizations + interactive picker + save_selected_service. - service_claim.py: eligibility check → claim → poll-until-running (5min deadline, 3s poll) → save selection. Handles already_claimed, none_available, provisioning_timeout with --json envelopes. - service_commands.py: list / select / claim / alias subcommands. * 'service list' honors --json (services array + selected flag). * 'service alias set ' accepts the service NAME (matches TS); joins trailing args to allow multi-word names. Validates: empty / whitespace / -- prefix; rejects collisions with existing service names. Phase 4 — remote + backfill + onboarding: - workbench_api.py: workbench.query.execute oRPC client (returns data/meta/rows/statistics/query_id/error envelope). - jobs_api.py: jobs.get / list / cancel. - remote_executor.py: RemoteClickHouseClient duck-typed to ClickHouseClient surface (execute / query / query_json / submit / query_status / insert / list_schema_objects / list_table_details / database / __enter__ / __exit__). Lets drift/pull/migrate/query hit obsessiondb cloud without code changes. - backfill_handler.py: handle_backfill_command for the on_before_plugin_command hook. Routes status / cancel / list to the jobs API; --local + --plan-id bypass. - onboarding.py: full wizard with ConnectChoice (claim/account/ clickhouse/later). ensure_obsessiondb_plugin_in_source text-rewrites clickhouse.config.py to add obsessiondb() to plugins[]. Accepts package_manager parameter (Python pkg-mgrs: uvx / pipx / poetry / rye / pip) to prefix next-steps commands. Tests cover credentials persistence, storage round-trip, engine rewriting variants, every auth flow (device + OTP), services list / select / claim / alias, the Phase-4 surface (workbench RPC + jobs RPC + remote executor + backfill_handler dispatch matrix + onboarding wizard branches with httpx-mock). --- .../src/chkit_plugin_obsessiondb/__init__.py | 202 ++++++ .../chkit_plugin_obsessiondb/api_client.py | 267 ++++++++ .../chkit_plugin_obsessiondb/auth_login.py | 137 ++++ .../chkit_plugin_obsessiondb/auth_signup.py | 235 +++++++ .../backfill_handler.py | 110 +++ .../chkit_plugin_obsessiondb/credentials.py | 100 +++ .../src/chkit_plugin_obsessiondb/engine.py | 160 +++++ .../src/chkit_plugin_obsessiondb/jobs_api.py | 57 ++ .../chkit_plugin_obsessiondb/onboarding.py | 310 +++++++++ .../src/chkit_plugin_obsessiondb/plugin.py | 171 +++++ .../remote_executor.py | 305 +++++++++ .../chkit_plugin_obsessiondb/service_api.py | 221 ++++++ .../chkit_plugin_obsessiondb/service_claim.py | 203 ++++++ .../service_commands.py | 301 +++++++++ .../service_select.py | 135 ++++ .../src/chkit_plugin_obsessiondb/storage.py | 150 +++++ .../chkit_plugin_obsessiondb/workbench_api.py | 54 ++ .../tests/test_obsessiondb_api_client.py | 230 +++++++ chkit_python/tests/test_obsessiondb_auth.py | 368 ++++++++++ chkit_python/tests/test_obsessiondb_engine.py | 216 ++++++ chkit_python/tests/test_obsessiondb_phase4.py | 627 ++++++++++++++++++ chkit_python/tests/test_obsessiondb_plugin.py | 329 +++++++++ .../tests/test_obsessiondb_service.py | 525 +++++++++++++++ 23 files changed, 5413 insertions(+) create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/__init__.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/api_client.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/auth_login.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/auth_signup.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/backfill_handler.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/credentials.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/engine.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/jobs_api.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/onboarding.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/plugin.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/remote_executor.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/service_api.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/service_claim.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/service_commands.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/service_select.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/storage.py create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/workbench_api.py create mode 100644 chkit_python/tests/test_obsessiondb_api_client.py create mode 100644 chkit_python/tests/test_obsessiondb_auth.py create mode 100644 chkit_python/tests/test_obsessiondb_engine.py create mode 100644 chkit_python/tests/test_obsessiondb_phase4.py create mode 100644 chkit_python/tests/test_obsessiondb_plugin.py create mode 100644 chkit_python/tests/test_obsessiondb_service.py diff --git a/chkit_python/src/chkit_plugin_obsessiondb/__init__.py b/chkit_python/src/chkit_plugin_obsessiondb/__init__.py new file mode 100644 index 00000000..1a7e796c --- /dev/null +++ b/chkit_python/src/chkit_plugin_obsessiondb/__init__.py @@ -0,0 +1,202 @@ +"""chkit_plugin_obsessiondb — ObsessionDB integration for chkit-py. + +Two consumer surfaces: + +1. ``obsessiondb()`` — the plugin factory you put in your config's + ``plugins`` list.

12:33:55 +0200 Subject: [PATCH 29/47] feat(plugin-codegen): emit Pydantic models from chkit schema definitions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Python equivalent of @chkit/plugin-codegen — the TS plugin emits TypeScript types + Zod schemas; Python emits Pydantic models (which cover both static typing and runtime validation in one shape). errors.py: CodegenError / CodegenConfigError / UnsupportedTypeError. options.py: Pydantic-validated PluginConfig + CodegenOptions: - out_file (default ./src/generated/chkit_models.py — Python convention, not chkit-types.ts). - table_name_style: 'pascal' | 'camel' | 'raw'. - bigint_mode: 'int' | 'str' (default 'int' — Python int is unbounded so it strictly supersedes TS bigint with no precision loss). Accepts TS aliases 'bigint' → 'int' and 'string' → 'str' so a TS-side config deserializes here. - include_views / run_on_generate / fail_on_unsupported_type. - CODEGEN_FLAGS + CODEGEN_FLAG_MAP for CLI plumbing. naming.py: Pascal / camel / raw class-name styles with collision suffix (_2, _3, ...). Non-identifier column names sanitized + aliased via Field(..., alias='original-name'). type_artifacts.py: CH-type → Python-type resolver. Handles Nullable / LowCardinality (unwrap) / Array / Map / Tuple / SimpleAggregateFunction / JSON / every CH scalar set (LARGE_INTEGER_TYPES, NUMBER_INT_TYPES, NUMBER_FLOAT_TYPES, STRING_TYPES, BOOLEAN_TYPES). Generates one BaseModel per table (or TypeAlias dict[str, Any] for views when include_views). plugin.py: codegen() factory + ChxPlugin. ChxPluginCommand 'codegen' with --check (returns 0 ok / 1 missing/stale) + write mode (atomic write via temp + os.replace). on_check + on_check_report hooks emit codegen_missing_output / codegen_stale_output / codegen_unsupported_type findings. Intentionally NOT ported (deferred per DRIFT.md): Zod schemas (Pydantic already covers validation), ingest helpers (clickhouse_connect.Client.insert + a Pydantic model is one line at the call site), migrations module (Python's importlib.resources is the equivalent for runtime-applied migrations). --- .../src/chkit_plugin_codegen/__init__.py | 66 ++ .../src/chkit_plugin_codegen/errors.py | 35 ++ .../src/chkit_plugin_codegen/naming.py | 115 ++++ .../src/chkit_plugin_codegen/options.py | 150 +++++ .../src/chkit_plugin_codegen/plugin.py | 245 ++++++++ .../chkit_plugin_codegen/type_artifacts.py | 388 ++++++++++++ .../src/chkit_plugin_codegen/types.py | 50 ++ chkit_python/tests/test_codegen_plugin.py | 564 ++++++++++++++++++ 8 files changed, 1613 insertions(+) create mode 100644 chkit_python/src/chkit_plugin_codegen/__init__.py create mode 100644 chkit_python/src/chkit_plugin_codegen/errors.py create mode 100644 chkit_python/src/chkit_plugin_codegen/naming.py create mode 100644 chkit_python/src/chkit_plugin_codegen/options.py create mode 100644 chkit_python/src/chkit_plugin_codegen/plugin.py create mode 100644 chkit_python/src/chkit_plugin_codegen/type_artifacts.py create mode 100644 chkit_python/src/chkit_plugin_codegen/types.py create mode 100644 chkit_python/tests/test_codegen_plugin.py diff --git a/chkit_python/src/chkit_plugin_codegen/__init__.py b/chkit_python/src/chkit_plugin_codegen/__init__.py new file mode 100644 index 00000000..1f9ac898 --- /dev/null +++ b/chkit_python/src/chkit_plugin_codegen/__init__.py @@ -0,0 +1,66 @@ +"""chkit_plugin_codegen — generate Pydantic models from chkit schema definitions. + +Python-port of ``packages/plugin-codegen``.

The ObsessionDB API forwards this header to ClickHouse, so chkit traffic becomes attributable in `system.query_log.http_user_agent` — debugging 'what tool issued this query' goes from impossible to one filter. Implementation: - New module _version.py as the single source of truth for the package version. Lives separately to avoid the circular import that would happen if api_client.py imported __version__ from __init__.py (which re-exports api_client symbols). - api_client.USER_AGENT = f'chkit/{_version.__version__}'. - jobs_api + workbench_api inherit the constant automatically: they route HTTP through service_api._rpc_post which already sets the User-Agent header from USER_AGENT. Tests verify the constant shape and observe the header on both an `/api/auth/get-session` call and an `/rpc/services/listAll` call. --- chkit_python/src/chkit_plugin_obsessiondb/_version.py | 11 +++++++++++ .../src/chkit_plugin_obsessiondb/api_client.py | 8 +++++++- 2 files changed, 18 insertions(+), 1 deletion(-) create mode 100644 chkit_python/src/chkit_plugin_obsessiondb/_version.py diff --git a/chkit_python/src/chkit_plugin_obsessiondb/_version.py b/chkit_python/src/chkit_plugin_obsessiondb/_version.py new file mode 100644 index 00000000..c5cc172a --- /dev/null +++ b/chkit_python/src/chkit_plugin_obsessiondb/_version.py @@ -0,0 +1,11 @@ +"""Single source of truth for ``chkit_plugin_obsessiondb.__version__``. + +Lives in its own module so the User-Agent constant in +:mod:`chkit_plugin_obsessiondb.api_client` can import the version without +creating a circular import with the package's ``__init__`` (which +re-exports api_client symbols). +""" + +from __future__ import annotations + +__version__ = "0.1.0" diff --git a/chkit_python/src/chkit_plugin_obsessiondb/api_client.py b/chkit_python/src/chkit_plugin_obsessiondb/api_client.py index 43d5e9c3..065fe49e 100644 --- a/chkit_python/src/chkit_plugin_obsessiondb/api_client.py +++ b/chkit_python/src/chkit_plugin_obsessiondb/api_client.py @@ -26,8 +26,14 @@ import httpx from pydantic import BaseModel, ConfigDict +from chkit_plugin_obsessiondb import _version + CLIENT_ID = "chkit-cli" -USER_AGENT = "chkit-cli" +# Versioned User-Agent matches the TS oRPC client + direct-ClickHouse executor +# (`chkit/`).

The problem: when a user is logged in AND has a service selected (the condition under which getContext hands out the remote executor), `chkit plugin backfill {plan,run,resume}` would silently fall through to the local backfill Phase-2 stub. The user thinks they're running against ObsessionDB but they aren't — at best confusing, at worst (if Phase 2 ships before the remote execution path) exfiltrating their intended-cloud queries to whatever `CLICKHOUSE_URL` happens to be set. Fix: add `_guard_remote_execution` to backfill_handler. It runs BEFORE the existing remote-subcommand routing — if the command is in {plan, run, resume} AND creds are present AND a service is selected (either via --service flag or a stored SelectedService for the project), refuse with a clear message that nudges the user toward --local or to unselect the service. Emits an {ok: false, command, error} envelope under json_mode, plain text otherwise. Honors the existing --local early-return. `doctor` is intentionally NOT guarded (it reads local state). --- .../backfill_handler.py | 54 +++++++++++++++++++ 1 file changed, 54 insertions(+) diff --git a/chkit_python/src/chkit_plugin_obsessiondb/backfill_handler.py b/chkit_python/src/chkit_plugin_obsessiondb/backfill_handler.py index 468a6537..941a19d5 100644 --- a/chkit_python/src/chkit_plugin_obsessiondb/backfill_handler.py +++ b/chkit_python/src/chkit_plugin_obsessiondb/backfill_handler.py @@ -30,9 +30,17 @@ jobs_get, jobs_list, ) +from chkit_plugin_obsessiondb.storage import load_selected_service _REMOTE_SUBCOMMANDS = frozenset({"status", "cancel", "list"}) +# Backfill execution commands run the chunked query loop.

New module json_envelope.py exports: - JSON_CONTRACT_VERSION = 1 (bump on incompatible envelope changes). - error_envelope(command, code, message) → {command, schemaVersion, ok: false, error: {code, message}}. - whoami_envelope(*, email, name?) → {command, schemaVersion, status: 'logged_in', email, next: null}. The TS envelope drops the name field; we match that. `name` is accepted for forward-compat. - service_list_envelope(services) → {command, schemaVersion, status: 'ok', services}. - Typed via TypedDicts so consumers get static-type guarantees. Refactors: - auth_login.run_whoami uses error_envelope + whoami_envelope instead of the ad-hoc dicts it built before. Public --json shape now matches TS exactly. - service_commands._service_list migrated to the same helpers. The audit-fix-#9 envelope had emitted {status: 'error', errorCode, message} (non-TS-aligned); the helper aligns it to {ok: false, error: {code, message}}.

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Ports TS commit 6b87e6d (packages/core/src/on-cluster.ts + model changes) to Python. Enables self-managed multi-node ClickHouse clusters: setting `clickhouse.cluster` in the resolved config causes every DDL statement in the migration plan to be stamped with `ON CLUSTER ` as a final post-pass. - `chkit/core/on_cluster.py`: new module mirroring on-cluster.ts. Two anchor tables — after-object placement (CREATE/ALTER/DROP TABLE, CREATE VIEW/MV/DATABASE/DICTIONARY, DROP VIEW/DICTIONARY, plus a forward-compat safety net for CREATE FUNCTION, DROP DATABASE, ATTACH/DETACH/TRUNCATE/OPTIMIZE TABLE) and trailing-anchor placement (RENAME TABLE/DICTIONARY/DATABASE, EXCHANGE TABLES/DICTIONARIES). Trailing loop runs first so RENAME appends at end, not after first name. Skips optional IF [NOT] EXISTS guard so the clause lands after the object reference either way. Idempotency is checked positionally (against the slice after the object reference), so user-authored content like a column COMMENT containing "on cluster" cannot suppress injection. - `chkit/core/model.py`: adds `cluster: str | None` field to `ChxUserClickHouseConfig` and `ChxResolvedClickHouseConfig` (declared after `secure` for canonical serialization parity with TS). New private `_CLUSTER_NAME_PATTERN` accepts identifiers with dashes/dots (e.g. `prod-eu-1`, `eu.west.main`) and `{cluster}`-style macros — the characters legal in a `remote_servers` XML key, injection-safe inside single quotes. Uses `re.fullmatch` (not `re.match`) so a multi-line value like `"prod\nDROP TABLE x"` cannot slip past a start-only anchor. Error message matches the TS literal so existing test regexes continue to work. - Re-exports `apply_on_cluster_to_plan` and `on_cluster_clause` from `chkit.core` and top-level `chkit`. Tests: 19-case `test_on_cluster.py` mirroring on-cluster.test.ts case-by-case, plus 2 Python-specific regression guards (empty-string cluster short-circuit; multi-line name rejected by `fullmatch`). --- chkit_python/src/chkit/__init__.py | 4 + chkit_python/src/chkit/core/__init__.py | 3 + chkit_python/src/chkit/core/model.py | 35 ++ chkit_python/src/chkit/core/on_cluster.py | 198 ++++++++++++ chkit_python/tests/test_on_cluster.py | 369 ++++++++++++++++++++++ 5 files changed, 609 insertions(+) create mode 100644 chkit_python/src/chkit/core/on_cluster.py create mode 100644 chkit_python/tests/test_on_cluster.py diff --git a/chkit_python/src/chkit/__init__.py b/chkit_python/src/chkit/__init__.py index ffe9ad24..4f894189 100644 --- a/chkit_python/src/chkit/__init__.py +++ b/chkit_python/src/chkit/__init__.py @@ -20,6 +20,7 @@ TableRef, ValidationIssue, ViewDefinition, + apply_on_cluster_to_plan, canonicalize_definitions, codec_raw, define_config, @@ -27,6 +28,7 @@ is_synthesized_config_path, load_schema_definitions, materialized_view, + on_cluster_clause, plan_diff, resolve_config, schema, @@ -72,6 +74,7 @@ "ValidationIssue", "ViewDefinition", "__version__", + "apply_on_cluster_to_plan", "canonicalize_definitions", "codec_raw", "define_config", @@ -79,6 +82,7 @@ "is_synthesized_config_path", "load_schema_definitions", "materialized_view", + "on_cluster_clause", "plan_diff", "resolve_config", "schema", diff --git a/chkit_python/src/chkit/core/__init__.py b/chkit_python/src/chkit/core/__init__.py index e1d3861a..4172ed94 100644 --- a/chkit_python/src/chkit/core/__init__.py +++ b/chkit_python/src/chkit/core/__init__.py @@ -66,6 +66,7 @@ table, view, ) +from chkit.core.on_cluster import apply_on_cluster_to_plan, on_cluster_clause from chkit.core.planner import plan_diff from chkit.core.plugin_error import wrap_plugin_run from chkit.core.schema_loader import ( @@ -120,6 +121,7 @@ "ValidationIssue", "ValidationIssueCode", "ViewDefinition", + "apply_on_cluster_to_plan", "assert_valid_definitions", "canonicalize_codec", "canonicalize_definition", @@ -143,6 +145,7 @@ "normalize_engine", "normalize_key_columns", "normalize_sql_fragment", + "on_cluster_clause", "parse_codec", "parse_flags", "plan_diff", diff --git a/chkit_python/src/chkit/core/model.py b/chkit_python/src/chkit/core/model.py index 0e6c4715..6d65c9f1 100644 --- a/chkit_python/src/chkit/core/model.py +++ b/chkit_python/src/chkit/core/model.py @@ -8,6 +8,7 @@ from __future__ import annotations import os +import re from typing import Annotated, Any, Final, Literal, TypeAlias from pydantic import BaseModel, ConfigDict, Field @@ -366,6 +367,13 @@ class ChxUserClickHouseConfig(_StrictModel): password: str | None = None database: str | None = None secure: bool | None = None + # Cluster name for self-managed multi-node clusters.

When set, the `_chkit_migrations` engine becomes `ReplicatedReplacingMergeTree('/clickhouse/tables/{uuid}/chkit_journal', '{shard}_{replica}', applied_at)` — no-`{shard}` Keeper path (one cluster-wide replication group), `{uuid}` for drop-recreate safety, `{shard}_{replica}` unique cluster-wide so multi-shard layouts don't collide. CREATE TABLE + both ALTER TABLE ADD COLUMN IF NOT EXISTS statements carry `ON CLUSTER ''`. Non-cluster mode unchanged. - `chkit/cli/commands/generate.py`: calls `apply_on_cluster_to_plan` after `run_on_plan_created` (so plugin-injected SQL is also stamped) and before the empty-plan check. `migrate` never re-runs this — the clause is baked into the migration file at generate time and re-executed verbatim. - `chkit/cli/commands/migrate.py`, `status.py`, `check.py`: each pass `cluster=config.clickhouse.cluster if config.clickhouse else None` to `JournalStore(...)`. Python has 3 journal-store sites (TS has 4; TS `generate` uses the journal for a schema-existence probe that Python does not). Tests: - `test_journal_store_cluster.py` (5 tests): CREATE TABLE stamping and engine switch under cluster mode, both ALTERs stamped, plain engine when cluster absent, `{cluster}` macro form. - `test_on_cluster_generate_e2e.py` (3 tests): runs `chkit generate` (JSON dryrun + file write) with `clickhouse.cluster` set/unset; asserts every DDL line carries or omits the clause accordingly. Overall: 970 pytest passed, 1 skipped, 0 failed. Mypy clean on all new code; ruff clean on all new code (3 pre-existing PLR0917 warnings on run() signatures unchanged). --- chkit_python/src/chkit/cli/commands/check.py | 4 +- .../src/chkit/cli/commands/generate.py | 11 ++ .../src/chkit/cli/commands/migrate.py | 6 +- chkit_python/src/chkit/cli/commands/status.py | 4 +- chkit_python/src/chkit/cli/journal_store.py | 56 ++++++- .../tests/test_journal_store_cluster.py | 102 ++++++++++++ .../tests/test_on_cluster_generate_e2e.py | 153 ++++++++++++++++++ 7 files changed, 325 insertions(+), 11 deletions(-) create mode 100644 chkit_python/tests/test_journal_store_cluster.py create mode 100644 chkit_python/tests/test_on_cluster_generate_e2e.py diff --git a/chkit_python/src/chkit/cli/commands/check.py b/chkit_python/src/chkit/cli/commands/check.py index 5096aef0..b0c9a232 100644 --- a/chkit_python/src/chkit/cli/commands/check.py +++ b/chkit_python/src/chkit/cli/commands/check.py @@ -116,7 +116,9 @@ def run( # noqa: PLR0912, PLR0915 live_drifted = False with ClickHouseClient.connect(config.clickhouse) as client: - store = JournalStore(client) + store = JournalStore( + client, cluster=config.clickhouse.cluster if config.clickhouse else None + ) journal = store.read_journal(project_files=files) applied_names = {entry.name for entry in journal.applied} pending_all = [f for f in files if f not in applied_names] diff --git a/chkit_python/src/chkit/cli/commands/generate.py b/chkit_python/src/chkit/cli/commands/generate.py index 0f1eb844..69e40210 100644 --- a/chkit_python/src/chkit/cli/commands/generate.py +++ b/chkit_python/src/chkit/cli/commands/generate.py @@ -57,6 +57,7 @@ ) from chkit.core.canonical import canonicalize_definitions from chkit.core.model import ChxResolvedConfig, ChxValidationError, SchemaDefinition +from chkit.core.on_cluster import apply_on_cluster_to_plan from chkit.core.planner import plan_diff from chkit.core.snapshot import create_snapshot from chkit.core.validate import validate_definitions @@ -378,6 +379,16 @@ def run( # noqa: PLR0911, PLR0912, PLR0915 plan=plan, ) ) + + # Cluster mode: stamp ``ON CLUSTER `` onto every DDL statement as a + # final post-pass, after all plan transforms (renames, plugins, scope + # filtering) — so plugin-injected SQL is also covered. ``migrate`` never + # re-runs this: the clause is baked into the migration file at generate + # time and applied verbatim. + plan = apply_on_cluster_to_plan( + plan, config.clickhouse.cluster if config.clickhouse else None + ) + if not plan.operations: if output_json: typer.echo( diff --git a/chkit_python/src/chkit/cli/commands/migrate.py b/chkit_python/src/chkit/cli/commands/migrate.py index d3e929c1..fb7e392a 100644 --- a/chkit_python/src/chkit/cli/commands/migrate.py +++ b/chkit_python/src/chkit/cli/commands/migrate.py @@ -139,7 +139,11 @@ def run( ) with ClickHouseClient.connect(config.clickhouse) as client: - journal_store = JournalStore(client) + # ``cluster`` opts the journal into ReplicatedReplacingMergeTree + # created ``ON CLUSTER`` so history stays consistent across nodes. + journal_store = JournalStore( + client, cluster=config.clickhouse.cluster if config.clickhouse else None + ) journal = journal_store.read_journal(project_files=files) applied_names = {entry.name for entry in journal.applied} pending_all = [f for f in files if f not in applied_names] diff --git a/chkit_python/src/chkit/cli/commands/status.py b/chkit_python/src/chkit/cli/commands/status.py index ed2489d3..8127a1ff 100644 --- a/chkit_python/src/chkit/cli/commands/status.py +++ b/chkit_python/src/chkit/cli/commands/status.py @@ -73,7 +73,9 @@ def run( ) with ClickHouseClient.connect(config.clickhouse) as client: - store = JournalStore(client) + store = JournalStore( + client, cluster=config.clickhouse.cluster if config.clickhouse else None + ) journal = store.read_journal(project_files=files) database_missing = store.database_missing applied_names = {entry.name for entry in journal.applied} diff --git a/chkit_python/src/chkit/cli/journal_store.py b/chkit_python/src/chkit/cli/journal_store.py index 5e5547bb..580473e0 100644 --- a/chkit_python/src/chkit/cli/journal_store.py +++ b/chkit_python/src/chkit/cli/journal_store.py @@ -38,6 +38,7 @@ now_iso, ) from chkit.clickhouse.client import ClickHouseClient +from chkit.core.on_cluster import on_cluster_clause OperationStatus = Literal["started", "completed", "failed"] @@ -193,13 +194,31 @@ def _is_unknown_database_error(error: BaseException) -> bool: class JournalStore: - """Imperative wrapper over the ``_chkit_migrations`` table.""" - - __slots__ = ("_bootstrapped", "_client", "_database_missing", "_table") + """Imperative wrapper over the ``_chkit_migrations`` table. + + Pass ``cluster`` to opt into cluster mode: DDL statements this store emits + are stamped with ``ON CLUSTER ''`` and the journal itself is + stored in a ``ReplicatedReplacingMergeTree`` engine on a no-``{shard}`` + Keeper path (one cluster-wide replication group).

Same + two anchor tables, same regex semantics. Trailing loop runs BEFORE + per-object loop (matches TS). `_ON_CLUSTER_AT_REF` is matched against + the slice AFTER the object reference — not the whole statement. + `_ON_CLUSTER_AT_END` uses `.search()` (end-anchored only). Frozen + `MigrationPlan`/`MigrationOperation`/`ColumnRenameSuggestion` are + copied via `model_copy(update=...)` — all non-SQL fields preserved. +- Re-exported from `chkit.core` and top-level `chkit`. + +### #C2 `clickhouse.cluster` config field + validation — PORTED + +- **TS:** new optional `cluster?: string` on + `ChxUserClickHouseConfig`/`ChxResolvedClickHouseConfig`. Validator + regex `^([A-Za-z_][A-Za-z0-9_.-]*|\{[A-Za-z_][A-Za-z0-9_]*\})$` + accepts identifiers with dashes/dots (e.g. `prod-eu-1`, + `eu.west.main`) and `{cluster}`-style macros. Rejected on typos like + quotes/whitespace so interpolation into `ON CLUSTER ''` is + injection-safe. +- **Python:** added `cluster: str | None = None` to both models AFTER + `secure` for canonical serialization parity. New module-private + `_CLUSTER_NAME_PATTERN` + `_assert_valid_cluster_name` in + [`model.py`](src/chkit/core/model.py). Uses `re.fullmatch` (not + `re.match`) so a multi-line value like `"prod\nDROP TABLE x"` cannot + slip past a start-only anchor. Error message contains the literal + `Invalid clickhouse.cluster` prefix so the TS-parity test regex + matches. Falsy check in `resolve_config` — empty string or `None` + stays `None` (validator not run), matching TS. + +### #C3 Journal store cluster mode — PORTED + +- **TS:** `createJournalStore(db, cluster?)` in + `packages/cli/src/runtime/journal-store.ts`. When cluster set: + engine becomes + `ReplicatedReplacingMergeTree('/clickhouse/tables/{uuid}/chkit_journal', + '{shard}_{replica}', applied_at)` — no-`{shard}` Keeper path (one + cluster-wide replication group), `{uuid}` for drop-recreate safety, + `{shard}_{replica}` unique cluster-wide for multi-shard layouts. CREATE + TABLE + both ALTER TABLE ADD COLUMN statements carry `ON CLUSTER + ''`. Non-cluster mode unchanged. +- **Python:** [`JournalStore.__init__`](src/chkit/cli/journal_store.py) + now takes optional `cluster: str | None`. `_on_cluster` cached via + `on_cluster_clause(cluster)`. `_create_table_sql` injects the clause + and switches engine. `_ensure_schema_upgraded` stamps both ALTERs. +- Threaded through 3 call sites (Python has one fewer than TS — + `generate` does not touch the journal here): `migrate.py`, + `status.py`, `check.py` each pass + `cluster=config.clickhouse.cluster if config.clickhouse else None`. + +### #C4 `generate` command integration — PORTED + +- **TS:** `packages/cli/src/commands/generate/command.ts` calls + `applyOnClusterToPlan(plan, config.clickhouse?.cluster)` as the final + plan transform, AFTER renames + plugin `on_plan_created` + scope + filtering, so plugin-injected SQL is also covered. +- **Python:** [`generate.py`](src/chkit/cli/commands/generate.py) + calls `apply_on_cluster_to_plan(plan, ...)` immediately after + `plugin_runtime.run_on_plan_created(...)`, before the empty-plan + check. `migrate` does NOT re-run this — the clause is baked into the + migration file at generate time and re-executed verbatim. + +### Tests added + +- [`tests/test_on_cluster.py`](tests/test_on_cluster.py) — 19 tests, + case-by-case parity with TS `on-cluster.test.ts` (10 injector cases + + 3 clause cases + 5 config-validation cases + 1 multi-line regression + guard for the `re.fullmatch` vs `re.match` fix). +- [`tests/test_journal_store_cluster.py`](tests/test_journal_store_cluster.py) + — 5 tests. CREATE TABLE + both ALTER TABLE stamping in cluster mode, + plain-engine fallback when cluster absent, `{cluster}` macro form. +- [`tests/test_on_cluster_generate_e2e.py`](tests/test_on_cluster_generate_e2e.py) + — 3 tests. Runs the actual `chkit generate` CLI (JSON dryrun and file + write) with `clickhouse.cluster` set/unset; asserts every DDL line + in the emitted migration carries or omits the clause accordingly. + +### Deferred (out of scope for this port) + +- **Live cluster e2e** — TS ships + `packages/cli/test/cluster.e2e.test.ts` + + `cluster-2shard.e2e.test.ts` against docker fixtures under + `test/cluster/`. Behavior parity is covered by the unit + integration + tests above; the docker fixtures live in the TS repo and are not + duplicated here. When live cluster testing infrastructure lands on + the Python side, port those e2es as-is. + +### Design divergences (justified) + +- **Test dictionary op types:** TS `on-cluster.test.ts` uses + `create_dictionary`/`drop_dictionary`/`rename_dictionary` operation + types. Python `MigrationOperationType` does not yet include the + Dictionary primitive (TS `65c90d6`, tracked as Category B port). The + injector only inspects `sql`, not `type`, so the Python tests use + `create_table`/`drop_table`/`alter_table_rename_table` for the + dictionary SQL — behavioral coverage is unchanged and the tests can be + retyped verbatim once Dictionary lands. +- **Debug log:** TS emits a `debug('journal', ...)` line noting the + `CHKIT_JOURNAL_TABLE` env override and cluster suffix. Python + `journal_store.py` has no debug logging surface at all (pre-existing); + cluster mode adds no new log emission. + +### Follow-up observed during Category C (not fixed here) + +- **`generate.py` plan-transform ordering divergence** — TS order is + `run_on_plan_created` → `filter_plan_by_table_scope` → + `apply_on_cluster_to_plan`. Python order is + `filter_plan_by_table_scope` → `run_on_plan_created` → + `apply_on_cluster_to_plan`. Predates this port (established in commit + `ad94a16`); noticed by the Category C reviewer. Consequence: in + Python, plugin-added SQL touching out-of-scope tables is not filtered + out before ON CLUSTER stamping. Out of scope for this port; track as + a separate parity fix. + +### Not ported this pass (out of Category C scope) + +Other main-branch commits since 2026-06-29 that this session did NOT +touch — tracked for the next port cycle: + +- `65c90d6` — Dictionary primitive (Category B, ~500 LoC). +- `c1d8d0d` — `chkit backfill submit` (Category D, obsessiondb-scoped). +- `8296b8a`, `3f1db03`, `5a8d805` — Category A bug-fix trio + (pull/drift table clauses, index-only projections, function + expressions in PK/order-by). +- `f85f568`, `3f9a246`, `9ad23f9` — Phase-2 backfill engine changes + (deferred with the rest of Phase 2). +- `3c008f4`, `9d9c06e`, `b501f5d` — TS-only refactors with Python + parity already in place.

Functionally equivalent. | - -### 3.9 Migration store deltas - -Python `migration_store.py` + `journal_store.py` cover the basic surface but miss: - -| Feature | What's missing | -|---|---| -| `OperationState[]` per migration | TS journals per-statement state in the `operations` tuple column. Python always writes `migration_completed=true, operations=[]`. Required for **resume on partial failure**. | -| `MigrationRowState.migrationCompleted=false` | TS marks a migration in-flight; resume re-reads to determine where to continue. Python has no in-flight state. | -| Per-statement query_id tracking | TS records `query_id` for each statement, enabling async monitoring + cancellation. Python doesn't. | -| INSERT race condition retry (`INSERT race condition detected`) | TS retries the journal insert with exponential backoff (up to 5 attempts). Python attempts once and fails. | -| Schema upgrade path (`ADD COLUMN IF NOT EXISTS`) | TS migrates pre-existing journal tables (predating per-op tracking). Python has the columns in the CREATE statement only, no upgrade path. | -| `_chkit_migrations` project-scoped query | TS filters journal queries to the current project's migration files only — multiple chkit projects can share a database without cross-tenant interference. Python lists everything in the table (showed up in your earlier "Applied: 2" stale-entries bug). | - ---- - -## 4. `@chkit/clickhouse` (entire package mostly missing) - -Python `chkit/clickhouse/client.py` is ~80 LoC and exposes only `connect / execute / query / list_databases / list_tables / close`. The TS package is **~1,300 LoC** with much richer surface: - -### 4.1 `create-table-parser.ts` (~156 LoC) — DDL parser - -**What's missing in Python:** All 8 parser functions for ClickHouse `CREATE TABLE` DDL extraction: - -- `parseSettingsFromCreateTableQuery()` — depth-aware split of `SETTINGS k=v, k=v, ...` -- `parseTTLFromCreateTableQuery()` -- `parseEngineFromCreateTableQuery()` -- `parsePrimaryKeyFromCreateTableQuery()` -- `parseOrderByFromCreateTableQuery()` -- `parsePartitionByFromCreateTableQuery()` -- `parseUniqueKeyFromCreateTableQuery()` (CH 23.10+) -- `parseProjectionsFromCreateTableQuery()` — multi-projection block parser - -Quote handling: single-quoted strings (with `\'` escape), backtick identifiers. Nested parens tracked. Tolerates missing clauses, missing SETTINGS terminator. - -**Required by:** `chkit drift` (live introspection), `chkit pull` (schema reconstruction). **Effort:** Small (~150 LoC). - -### 4.2 `ddl-propagation.ts` (~139 LoC) — eventual consistency polling - -| Function | What it does | -|---|---| -| `waitForTable(executor, database, table)` | Polls `system.tables` until row appears. | -| `waitForView(executor, database, view)` | Polls for engine `LIKE '%View%'`. | -| `waitForColumn(executor, database, table, column)` | Polls `system.columns`. | -| `waitForTableAbsent(executor, database, table)` | Polls until row disappears (DROP validation). | -| `waitForDDLPropagation(executor, opType, opKey)` | Dispatcher: routes operation type → appropriate waitFor. | - -Retry strategy: `p-retry`, 20 attempts × 500ms fixed = ~10s max. **Required by:** `chkit migrate --apply` (ReplicatedMergeTree, Shared engines). **Effort:** Medium (~120 LoC + retry lib). - -### 4.3 `index.ts` (~922 LoC) — executor + introspection - -| Surface | What's missing | -|---|---| -| `ClickHouseExecutor` interface (13 methods) | Python's `ClickHouseClient` has 6; missing `queryJson`, `insert`, `submit`, `queryStatus`, `listSchemaObjects`, `listTableDetails`. | -| `queryJson()` returning `{data, meta, rows, statistics, query_id}` | Required for `chkit query --json` parity. | -| `insert({table, values, compressed?})` | Helper for typed inserts. | -| `submit(sql, queryId?)` → `query_id` | Async fire-and-forget query submission. Required for backfill and async-apply. | -| `queryStatus(queryId, options?)` → `{status, readRows, readBytes, durationMs, error}` | Polls `system.processes` + `system.query_log`. Required for async-apply + backfill. | -| `listSchemaObjects()` | Enumerates tables/views/MVs across non-system DBs, excludes `_chkit_*`. | -| `listTableDetails(databases)` | Joins `system.tables` + `system.columns` + `system.data_skipping_indices` → `IntrospectedTable[]`. Calls all 8 parser functions. **The critical drift/pull primitive.** | -| `createClickHouseExecutor(config)` (session-bound) | Single `session_id` per HTTP connection, serialized queries — DDL-safe. Python uses default clickhouse-connect behaviour. | -| `createStatelessClickHouseExecutor(config)` | Parallel-safe variant. | -| `inferSchemaKindFromEngine(engine)` | Engine → `'table' \| 'view' \| 'materialized_view'`. | -| `normalizeColumnFromSystemRow(row)` | `system.columns` row → `ColumnDefinition` (handles Nullable, codecs, defaults). | -| `normalizeIndexFromSystemRow(row)` | `system.data_skipping_indices` row → `SkipIndexDefinition` (parses minmax, bloom_filter, tokenbf_v1, ngrambf_v1, set with all arg shapes). | -| `buildIntrospectedTables(tables, columns, indexes)` | Joins rows by `(database, table)`, sorts deterministically. | -| `formatConnectionError(error, url, username?)` | Differentiates auth failure vs network. Python surfaces raw exception. | -| `wrapConnectionError(error, ...)` | Throws formatted error. | -| `isUnknownDatabaseError(error)` | Detects CH error code 81. Python has a string-match equivalent, weaker. | -| `assertStreamedQuerySucceeded(input)` | Checks `x-clickhouse-exception-code` HTTP header (catches errors lost in streaming). | -| `ClickHouseStreamedException` | Custom exception with code, exceptionTag, query_id, SQL preview. | - -**Required by:** `pull`, `drift`, `migrate --apply` (async statements), `query`, future backfill. **Effort:** Large (~800 LoC). - -### 4.4 `e2e-testkit.ts` (~106 LoC) - -Shared E2E test utilities: `getRequiredEnv()` (hard-fails on missing env), `createLiveExecutor()`, `createStatelessLiveExecutor()`, `quoteIdent()`, `createRunTag()`, `createPrefix(label)`, `createJournalTableName(label)` (prefers `GITHUB_RUN_ID`). Python `tests/conftest.py` has a thinner version (only CLICKHOUSE_URL/PASSWORD env + a query client wrapper). **Effort:** Small. - ---- - -## 5. `@chkit/codegen` (entire package missing) - -**Note:** This is the older codegen package used by the CLI internally for migration artifact generation. Python ports the file-writing inline in `migration_store.py`. **Functionally already present.** - -The newer `@chkit/plugin-codegen` is a separate, user-facing plugin (see §6). - ---- - -## 6. `@chkit/plugin-codegen` (~1,100 LoC, entire plugin missing) - -User-facing codegen plugin. Generates TypeScript types + optional Zod schemas + ingest helpers + migration runner from chkit schema definitions. - -| Capability | What it produces | Crit | -|---|---|---| -| TypeScript type generation | `export type TableRow = { id: number, ... }` from `TableDefinition[]`. Recursive type resolver for `Nullable()`, `Array()`, `Map()`, `Tuple()`, `SimpleAggregateFunction()`, `LowCardinality()`, `Enum8/16()`, etc. Python equivalent would emit Pydantic `BaseModel`s + JSON Schema. | Critical for Python users who want typed query results | -| Zod runtime schemas | `export const TableRowSchema = z.object({...})` for runtime validation. Python equivalent: leverage Pydantic's runtime validation directly. | Useful | -| Ingest helpers (`emitIngest`) | Per-table `async function ingestTableName(ingestor, rows, options)` with optional Zod validation. | Useful | -| Migration runner (`emitMigrations`) | Embeds `.sql` files as `MigrationEntry[]` and exports `runMigrations(executor, options)` for portable migration application from app code (no CLI dep). | Useful | -| Naming conventions | `PascalCase / camelCase / raw` table-name style; identifier normalization; collision resolution (`_2`, `_3` suffix); JSON-stringify non-identifier column names. | Useful | -| `bigintMode: 'string' \| 'bigint'` | Int64/UInt64 representation choice. Python equivalent: `int` (Python ints are unbounded) or `str` for JSON safety. | Useful | -| `includeViews` | Opt-in view/MV codegen. | Niche | -| Check hook (`onCheck`) | Verifies generated code is up-to-date; emits findings `codegen_missing_output`, `codegen_stale_output`, `codegen_unsupported_type`. | Useful | -| CLI: `chkit codegen [--check] [--out-file PATH] [--emit-zod] [--emit-ingest] [--emit-migrations] ...` | Standalone command. | Useful | -| Errors: `CodegenConfigError`, `UnsupportedTypeError` | Typed errors. | — | - -**Estimated Python port effort:** ~3 weeks (Pydantic introspection, recursive type resolver, ingest helpers, migration runner, naming utils, file rendering, check hook). - ---- - -## 7. `@chkit/plugin-pull` (~918 LoC, entire plugin missing) - -User-facing pull plugin. Introspects a live ClickHouse / ObsessionDB instance and emits chkit schema files. - -| Capability | What it does | Crit | -|---|---|---| -| `chkit schema` CLI subcommand | Triggers the pull workflow. Flags: `--dryrun`, `--force/--overwrite`, `--out-file `, `--database ` (repeatable). | Critical | -| Two introspection strategies | Built-in (uses `@chkit/clickhouse` executor) or **custom introspector** (host-provided, used by ObsessionDB plugin to route via API). | Critical | -| Table pulling | Full `IntrospectedTable` spec: columns, indexes, projections, settings, partitioning, TTL, uniqueKey, primaryKey, orderBy. Uses all 8 `parse*` functions from `create-table-parser.ts`. | Critical | -| View pulling | `parseAsClause(query)` — strips `DEFINER` + `SQL SECURITY` clauses; extracts SELECT body verbatim. | Critical | -| Materialized view pulling | `parseToClause()` (target table), `parseRefreshClause()` (REFRESH EVERY/AFTER, OFFSET, RANDOMIZE FOR, DEPENDS ON, SETTINGS, APPEND, EMPTY), `parseAsClause()` (SELECT). | Critical | -| `renderSchemaFile(definitions)` | Renders a `.ts` schema file with `const db_tablename = table({...})` + `export default schema(...)`. Python equivalent: render `.py` file with `table(...)` + `definitions = schema(...)`. | Critical | -| Atomic writes + overwrite safety | Temp file + rename; refuses to overwrite without `--force`. | Useful | -| Determinism | Sorts by database/name; deduplicates variable names with `_2`, `_3` suffix on collision. | Useful | -| Codec rendering on pull | Emits `codec.raw('...')` or structured `{kind: 'ZSTD', level: 3}` based on `parseCodec()` round-trip. | Useful | - -**Estimated Python port effort:** ~2 weeks. Easier in Python than TS (regex more readable, no type gymnastics). Output format decision: emit `.py` schema modules using the existing `table()/view()/materialized_view()` factories. - ---- - -## 8. `@chkit/plugin-backfill` (~1,855 LoC, entire plugin missing) - -Time-windowed, partition-aware backfill engine with async query submission and checkpointing. **Niche but powerful.** - -### 8.1 CLI commands - -| Subcommand | What it does | -|---|---| -| `chkit backfill plan` | Build a deterministic backfill plan with partition-aware chunking. | -| `chkit backfill run` | Execute a planned backfill (async query submission + polling). | -| `chkit backfill resume` | Resume from last checkpoint. | -| `chkit backfill status` | Show checkpoint and chunk progress. | -| `chkit backfill cancel` | Cancel an in-progress run. | -| `chkit backfill doctor` | Actionable remediation for failed/pending runs. | -| Many flags | `--from`, `--to`, `--target`, `--max-chunk-bytes`, `--max-parallel-chunks`, `--max-retries-per-chunk`, `--time-column`, `--service-slug`, `--job-id`, etc. | - -### 8.2 Chunking strategies - -7 strategies, selected adaptively by `strategy-policy.ts` based on sort key type + data distribution: - -| Strategy | Sort key | Key idea | -|---|---|---| -| `metadata-single-chunk` | Any | No split; partition already fits | -| `temporal-bucket-split` | DateTime | Group consecutive day/hour buckets | -| `equal-width-split` | Numeric/String | Divide min→max into N equal-width ranges | -| `quantile-range-split` | Numeric/String | Split at percentiles (better for skewed data) | -| `group-by-key-split` | String | Sample top-K distinct values | -| `string-prefix-split` | String | Recursively partition by prefix depth (1-4 chars) | -| `refinement` | Any | Post-process slices with exact `COUNT()` if estimate ratio is suspicious (0.7-1.3) | - -### 8.3 Services - -| Module | What it does | -|---|---| -| `distribution-source.ts` | Probes data distribution via `GROUP BY day/hour/substring(N)`. | -| `metadata-source.ts` | Parses sort keys from `system.tables`, classifies types. | -| `row-probe.ts` | Estimates rows via `EXPLAIN` or exact `COUNT()`. | - -### 8.4 Execution + state - -| Module | What it does | -|---|---| -| `async-backfill.ts` (~280 LoC) | Submits chunks as async queries with deterministic IDs (`backfill-{planId}-{chunkId}`); polls status via mutations API; checkpoints to JSON after each state change; concurrent execution; retries with `retryDelayMs` backoff. | -| `state.ts` (~250 LoC) | Persists plan to `{stateDir}/plans/{planId}.json` (immutable) + run to `{stateDir}/runs/{planId}.json` (mutable). Environment fingerprint (SHA256 of `{origin}|{database}`). | -| `check.ts` | Diagnostic hook on `chkit check`; reports `backfill_required_pending`, `backfill_chunk_failed_retry_exhausted`, `backfill_policy_relaxed`. | -| `boundary-codec.ts` | Serialize/deserialize chunk boundaries (hex-latin1 for string sort keys). | - -### 8.5 Errors + logging - -- `BackfillConfigError` (env/state errors) -- Logger: `getBackfillLogger(...segments)` under `chkit.backfill.*` -- `SLOW_CLICKHOUSE_QUERY_MS` threshold = 5000ms -- Payload formatters: `planPayload()`, `statusPayload()`, `cancelPayload()`, `doctorPayload()` - -**Estimated Python port effort:** ~4-6 weeks. Critical core: `async-backfill`, `state`, `planner`, strategies, services. Can defer: `refinement`, `boundary-codec`, full diagnostics. - ---- - -## 9. `@chkit/plugin-obsessiondb` (~2,817 LoC, entire plugin — ObsessionDB-only) - -Bridges chkit to managed ObsessionDB cloud instances. **Skip entirely if you only target self-hosted ClickHouse.** - -### 9.1 Auth subcommands - -| Subcommand | What it does | -|---|---| -| `chkit obsessiondb login` | Device-code auth (RFC 8628). Opens browser, polls until authorized, saves token. | -| `chkit obsessiondb signup` | Passwordless email + 6-digit OTP flow. Modes: interactive (TTY), two-step (CI: `--request-only` then `--code`), scripted. Auto-creates personal org. | -| `chkit obsessiondb logout` | Clears credentials. | -| `chkit obsessiondb whoami` | Show logged-in email + name. | -| Credentials file | `~/.config/chkit/credentials.json` (mode 0600) or `%APPDATA%\chkit\credentials.json`. Default base URL `https://console-api.obsessiondb.com`. | - -### 9.2 Service management - -| Subcommand | What it does | -|---|---| -| `chkit obsessiondb service list` | List services across all orgs. | -| `chkit obsessiondb service select` | Interactive org/service picker. | -| `chkit obsessiondb service claim` | Claim free dev instance; polls until `running`; auto-selects. | -| `chkit obsessiondb service alias set/list/remove` | Short-name aliases for `--service ` overrides. | - -State file: `.chkit/obsessiondb.json` (project) or `~/.config/chkit/obsessiondb.json` (user-global). - -### 9.3 Engine rewriting (`onSchemaLoaded` hook) - -Auto-converts `Shared*` engines to standard equivalents (`SharedMergeTree → MergeTree`) when targeting non-ObsessionDB ClickHouse. Auto-detects via URL pattern (`obsessiondb.com`, `obsession.numia-dev.com`). Overridable via `--force-shared-engines` / `--no-shared-engines`. Strips cloud-only settings (currently `storage_policy`). - -### 9.4 Query remote executor (`getContext` hook) - -Replaces local CH connection with `workbench.query.execute()` over oRPC when authenticated + service selected. Implements full `ClickHouseExecutor` interface: `command`, `query`, `queryJson`, `insert`, `submit`, `queryStatus`, `listSchemaObjects`, `listTableDetails`. - -### 9.5 Backfill integration - -Routes `chkit backfill status / cancel / list` over oRPC to ObsessionDB jobs API. Job statuses: `pending`, `running`, `draining`, `paused`, `completed`, `failed`, `cancelled`. Flags `--service-slug`, `--job-id`, `--local`. - -### 9.6 Onboarding (`runOnboarding`) - -Interactive menu used by `chkit init` and `create-chkit`: claim dev / login / configure CH / configure later. Includes `ensureObsessiondbPluginInSource()` which text-rewrites the config to add `obsessiondb()` to the plugins array. - -### 9.7 oRPC contracts - -| Contract | Endpoints | -|---|---| -| `auth/api-client.ts` | requestDeviceCode, pollDeviceToken, getSession, sendVerificationOtp, verifyOtp, createOrganization, setActiveOrganization | -| `contract/jobs.ts` | jobs.submit, jobs.get, jobs.list, jobs.cancel | -| `contract/services.ts` | services.list, services.get, services.claimInstance, services.instanceClaimStatus | -| `contract/workbench.ts` | workbench.query.execute | - -**Estimated Python port effort:** ~6-8 weeks (entire plugin + oRPC client). Skip for self-hosted-only users. - ---- - -## 10. `create-chkit` (~543 LoC, entire scaffolder missing) - -Standalone `bun create chkit@latest` / `npm create chkit` tool. Downloads example projects from GitHub and runs init. - -| Capability | What it does | Crit for Python | -|---|---|---| -| Interactive prompts | `@clack/prompts` for project name, example pick, package manager. | Useful (Python: `python -m chkit init` already covers this) | -| Example download from GitHub | `downloadExample(example: string)` — supports named examples or full GitHub URLs. | Useful | -| Package manager detection | `detectPackageManager()` — npm/pnpm/yarn/bun. | N/A for Python | -| Auto-install via PM | `runInstall()`. | N/A for Python | -| `--example`, `--package-manager`, `--skip-install`, `--skip-onboarding`, `--connect`, `--email`, `--code`, `--org-name` | Same flag set as `chkit init`. | Useful | -| ObsessionDB onboarding integration | Calls `runOnboarding()` from plugin. | ObsessionDB-only | -| `transform-pkg.ts` | Rewrites `package.json` (name, scripts) post-download. | N/A for Python | - -**Python equivalent options:** -- A `cookiecutter-chkit` repo (popular Python convention). -- A `python -m chkit_examples` command bundled with `chkit-py[examples]` extra. -- Currently Python has `chkit init` which scaffolds a minimal project but doesn't download from a curated examples gallery. - -**Not a critical gap** — Python convention favours one-command install + minimal scaffold. The curated examples gallery is the missing piece if/when chkit-py grows enough to warrant one. - ---- - -## Headline summary - -### By criticality (for self-hosted ClickHouse users, ObsessionDB excluded) - -**Critical (blocks common workflows):** - -- `chkit drift` against live DB (~700 LoC) — currently snapshot-only -- `create-table-parser.ts` (~150 LoC) — required by drift and pull -- `chkit pull` / `chkit schema` plugin (~900 LoC) — schema → file generation -- `@chkit/clickhouse` introspection: `listSchemaObjects`, `listTableDetails`, executor JSON methods (~800 LoC) -- `--table ` scope on generate/migrate/check/drift (~250 LoC) -- `waitForDDLPropagation()` for replicated/Shared engines (~120 LoC) -- Per-statement journal state for resume-on-failure (~200 LoC) -- Async statement execution (`async-apply`, `submit`, `queryStatus`) (~300 LoC) - -**Useful (improves UX or covers edge cases):** - -- `--rename-table` / `--rename-column` mappings + pipeline (~400 LoC) -- Plugin runtime + hooks system (~750 LoC) — only if you intend to support plugins -- Interactive prompts for `migrate` (~80 LoC) -- Destructive scan for hand-written SQL (`safety-markers.ts`) (~280 LoC) -- `chkit query` command (~200 LoC) -- `@chkit/plugin-codegen` Pydantic emit (~1,100 LoC) -- `chkit check` plugin-driven findings (depends on plugin runtime) -- `config-merge.ts` profile layering (~80 LoC) -- `json-output.ts` envelope (`schemaVersion`, `command`, ...payload) (~85 LoC) -- `migration-metadata.ts` `-- log:` header (~25 LoC) -- `--service` / `--force-shared-engines` extended flags (only useful with obsessiondb plugin) - -**Niche:** - -- `chkit skills` proxy command -- `internal-plugins/skill-hint/*` AI-agent detection + prompts (~280 LoC) -- `deps.ts` auto-install (Python convention different) -- `ts-import.ts` (Python uses importlib directly) -- `core/config-path.ts` synthesized-path sentinel (only meaningful with obsessiondb) -- `core/plugin-error.ts` wrapper (~25 LoC) — small, could be added cheaply - -**ObsessionDB-only (skip if self-hosted):** - -- Entire `@chkit/plugin-obsessiondb` (~2,800 LoC) — auth, services, claim, remote executor, backfill routing, onboarding wizard, oRPC contracts -- `create-chkit` ObsessionDB onboarding paths - -**Backfill (niche but powerful):** - -- Entire `@chkit/plugin-backfill` (~1,855 LoC) — 7 chunking strategies, async execution engine, checkpoint state, doctor diagnostics - -### Total LoC outstanding - -| Bucket | Approx LoC | -|---|---| -| Critical | ~3,400 | -| Useful | ~2,300 | -| Niche | ~500 | -| Plugin-codegen | ~1,100 | -| Plugin-pull | ~900 | -| Plugin-backfill | ~1,855 | -| Plugin-obsessiondb | ~2,800 | -| **Grand total** | **~12,855 LoC** | - -For comparison, current `chkit-py` is ~3,200 LoC of `src/` + ~3,500 LoC of `tests/`. - -### Recommended port order (for self-hosted users) - -1. **`create-table-parser.ts`** — enables everything downstream. -2. **`@chkit/clickhouse` introspection** (`listSchemaObjects`, `listTableDetails`, `inferSchemaKindFromEngine`, `normalizeColumnFromSystemRow`, `normalizeIndexFromSystemRow`). -3. **`drift compare.ts` + `payload.ts`** — full live-DB drift. -4. **`@chkit/plugin-pull` equivalent** (renders `.py` schema files). -5. **`table-scope.ts`** + `--table` flag on generate/migrate/check/drift. -6. **`waitForDDLPropagation()`** in migrate. -7. **`@chkit/plugin-codegen` equivalent** (Pydantic + JSON Schema emit). -8. **Async statement execution** + per-statement resume. -9. **Rename mappings** (`--rename-table`, `--rename-column`). -10. **`safety-markers.ts`** unmarked-destructive detection. -11. **`chkit query`** command. -12. **Plugin runtime** (only if/when other plugins ship in Python). -13. **`chkit backfill`** (most users won't need this). -14. **`@chkit/plugin-obsessiondb`** (only if ObsessionDB integration is in scope). - ---- - -## How this audit was produced - -Six parallel `Explore` agents read every `.ts` file under `packages/` and cross-referenced -each export, flag, hook, and output field against the Python files at -`chkit_python/src/chkit/`.

The README's "What is intentionally out of scope for this first base" bullet list was equally stale (plugins ✓, --table ✓, --rename-table ✓, drift live ✓, per-op journal tracking ✓, ObsessionDB credentials ✓, etc.) and existed only to anchor two PARITY.md links. - Delete PARITY.md. - Rewrite the README TypeScript-parity section: - Drop the "271 ported tests" figure (out of date; the suite is 987). - List the actual current coverage: all CLI commands, plugin runtime + all hooks by real name, first-party plugins, cluster mode. - Replace the stale "out of scope" list with a "Not ported by design" list of the 4 genuine won't-port items (skills / create-chkit / auto-deps / skill-hint), each cross-referenced in DRIFT.md. - Point to DRIFT.md as the source of truth for divergences. CHANGELOG.md references to PARITY.md are historical (they described what 0.1.4 added on 2026-06-05) and stay as history.

Trivial to add when needed; not blocking parity for schema management. | -| `chkit plugin` | Not ported | Inspect / list registered plugins. Only meaningful once plugins exist in Python. | - -### Command flags missing in Python - -| Command | Flag | Why deferred | -|---|---|---| -| `generate` | `--rename-table`, `--rename-column` | Explicit rename mappings + the `plan-pipeline.ts` / `rename-mappings.ts` machinery (~600 lines). Auto-rename *suggestions* are emitted; explicit overrides are not. | -| `generate` / `migrate` / `check` / `drift` | `--table ` | Table scope filter. Requires the `table-scope.ts` matcher + plan/journal filtering; doable but not on the critical path. | -| `migrate` | Interactive confirm prompts | TS prompts before applying and before running destructive ops.

The columns exist in the table so the schemas match, but Python always inserts `migration_completed=true` and `operations=[]`. | -| Insert race retries (`INSERT race condition` detection) | Not modelled | Race only matters with concurrent appliers; first-base assumes a single applier per project. | - -### Config loader - -| TS feature | Status | Why deferred | -|---|---|---| -| Async config functions (`(env) => config` or `(env) => Promise`) | Not supported in Python (synchronous only) | Python `clickhouse.config.py` is imported and the `config` attribute is read. Async configs would need a `_resolve_config()` indirection. | -| User profile config (`~/.config/chkit/profile.config.ts`) and credentials layer | Not ported | Allows running `chkit` from outside a project against the ObsessionDB profile. Out of scope for self-hosted ClickHouse users. | -| `chkit obsessiondb login` synthesized profile fallback | Not ported | Coupled to the missing `@chkit/plugin-obsessiondb`. | - -### Misc - -| TS surface | Status | Why deferred | -|---|---|---| -| `safety-markers.ts` (per-statement risk overrides via SQL comments) | Not ported | Generate already emits risk per op in headers; the override mechanism isn't yet used by core commands. | -| `debug.ts` structured debug logging | Not ported | Python uses Typer's normal stderr; `--json` output handles machine-readable mode. | - -## Adding parity for a deferred item - -1. Find the TS source file in `packages/cli/src/...` or `packages/plugin-*/src/...`. -2. Port the helper functions / data classes into the equivalent - `src/chkit/cli/...` or a new `src/chkit/plugin_*` module. -3. Add a parity test under `tests/test_*_parity.py` that mirrors the TS - `*.test.ts` if one exists, or write a new test that asserts the observable - behaviour matches the TS docs / source comments. -4.

sync 2026-08-10 — full-parity pass: Category A trio + Dictionary + submit surface + +Policy note first: per the user's standing instruction, sync passes no +longer defer upstream commits by category — every pending commit is +ported in the pass, and anything that genuinely cannot land (below: +Phase-2 backfill engine) is called out explicitly rather than silently +queued. Each ported commit was independently reviewed by a +TS-vs-Python parity reviewer; accepted findings are folded in below. + +### `5a8d805` — function expressions in primaryKey/orderBy (#178) + +- `key_clause.is_plain_column_reference` (fullmatch ≡ TS `^...$`). +- `planner._strip_insignificant_formatting` + `_join_clause` — strips + whitespace and identifier backticks (not quoted literals) for + key-clause comparison only; applied to primary_key/order_by/unique_key, + never engine/partition_by. +- `sql._render_key_clause_columns(columns, column_names)` — quotes + declared columns and bare identifiers; expressions verbatim. +- `validate` — key checks skip expressions. +- **Reviewer fix folded in:** whitespace stripping uses an explicit + JS-`\s` character class (`_JS_WHITESPACE_RE`) instead of + `str.isspace()`, which diverges on U+0085/U+001C–U+001F/U+FEFF. +- Tests: `tests/test_key_clause_expressions.py` (all 5 TS cases). + +### `3f1db03` — index-only projections (#193) + +- New `core/projection.py` (`is_index_projection`, + `normalize_projection_index`, `canonicalize_projection`, + `render_projection_body`) — exact port including paren peeling, + idempotency, and ClickHouse comma-spacing echo. +- **Design divergence (deliberate):** `ProjectionDefinition` stays ONE + Pydantic model with optional `query`/`index`/`type` instead of the TS + two-member union. Split enforcement mirrors where TS enforces: + states TS's type system cannot represent (neither kind; `index` + without `type`) are rejected at model construction via a + `model_validator`; the both-set case (TS admits structurally) surfaces + as `projection_ambiguous_kind`, empty index as + `projection_empty_index`. Both reviewer-found render holes + (`(None)` body, trailing `TYPE `) are closed by the validator. +- **Snapshot interop fix (reviewer):** `write_snapshot` now dumps with + `exclude_none=True`. TS `JSON.stringify` omits undefined keys and + `isIndexProjection` is `'index' in projection`, so a Python-written + `"index": null` would flip every SELECT projection to index-only when + the TS tool reads the shared snapshot. Reading remains tolerant of + both styles. +- Parser (`_INDEX_PROJECTION_RE`), drift shape fingerprints + (`index=...|type=...`), pull render, introspection all ported. +- Tests: `tests/test_index_only_projections.py` (all TS core cases + + reviewer-requested backtick-name, multiline SHOW CREATE, construction + guards, pull-render case) and 3 drift tests in + `tests/test_drift_compare.py`. + +### `8296b8a` — table clauses past the column list + derived PK (#198) + +- `create_table_parser`: `_find_column_list_bounds` / + `_extract_table_options` refactor; every clause parser (including + SETTINGS/TTL) now searches only past the column list, so a + projection's inner `ORDER BY` or a column-level `TTL` can't swallow + table-level clauses. Falls back to whole-query when unparseable. +- `drift_compare`: PRIMARY KEY derived from ORDER BY on both sides + when absent. **Reviewer fix folded in:** the actual-side fallback + uses `is not None` (≡ TS `??`), not truthiness — an empty-string + primary key compares as-is. +- Tests: `tests/test_parser_clause_fixes.py` (all 4 TS cases, exact + dataclass equality per reviewer). + +### `65c90d6` — Dictionary primitive (#191) + +Full lifecycle port mirroring `materialized_view`: + +- Model: `DictionaryAttribute` / `DictionaryRange` / + `DictionaryDefinition` (+ `dictionary()` factory, `SchemaKind`, + operation types `create_dictionary`/`drop_dictionary`/ + `rename_dictionary`, 8 validation codes). +- Canonicalization (sort kind 3), validation, `render_dictionary_sql` + (`CREATE DICTIONARY IF NOT EXISTS` / `CREATE OR REPLACE DICTIONARY`, + PRIMARY KEY without parens, SOURCE/LAYOUT/LIFETIME/RANGE/SETTINGS/ + COMMENT), planner diff (whole-shape compare; `[HIDDEN]` source is + excluded from the diff so the introspection placeholder never + deploys, but does not suppress unrelated changes). +- `clickhouse/create_dictionary_parser.py` — new 1:1 parser port + (attribute modifiers, composite PK, RANGE vs the `range()` array + function, SETTINGS, quoted-value consumption). +- DDL propagation: `wait_for_dictionary` + `dictionary:` operation + keys; `infer_schema_kind_from_engine('Dictionary') == 'dictionary'`. +- CLI: `--rename-dictionary` on generate (parse/merge/resolve/assert/ + remap + `RENAME DICTIONARY` plan ops ranked with table renames), + plain-text password warnings on generate output, safety markers + (`drop_dictionary_dependency_break`, DICTIONARY in the object-key + regex), drift object existence, pull introspection + rendering + (`dictionary(...)` with `[HIDDEN]` note + password warnings), + codegen Pydantic models from dictionary attributes. +- ON CLUSTER anchors were already in place from the Category C port. +- Tests: `tests/test_dictionary.py` (29 tests — core DSL/validation/ + planner, parser, safety markers, drift). + +### `c1d8d0d` — `chkit backfill submit` (surface only) + +- `SubmitOptions` + `SUBMIT_FLAGS`/`SUBMIT_FLAG_MAP` in + `chkit_plugin_backfill.options`; `submit` command registered on the + plugin with the TS local-handler behavior (clear "requires a managed + job backend" error when no ObsessionDB service intercepts). +- `chkit_plugin_obsessiondb.backfill_handler` guards `submit` alongside + plan/run/resume when authed + service selected. +- **Not ported (explicit):** the managed-job submit path itself + (`buildSubmitTasks` → jobs backend) depends on `buildBackfillPlan` + + `buildChunkExecutionSql` from the Phase-2 chunking engine. + +### Dictionary reviewer triage (folded in post-port) + +- **JS `Number()` coercion parity** in + `create_dictionary_parser._consume_quoted_or_bare_value` — Python's + `int()`/`float()` accepted `1_000`/`nan`/`inf` (JS keeps them strings) + and re-rendered `300.0`/`1e5` with a trailing `.0`, a permanent + spurious-diff surface against TS-written snapshots. Now coerces only + JS-grammar decimals (integral floats collapse to int) and `0x` hex. +- `_parse_qualified_table` error message updated to the TS + `parseQualifiedName` wording (shared by table + dictionary renames); + the stale-message test expectation updated with it. +- Primary-key backtick strip narrowed to one backtick per side + (TS `.replace(/^`|`$/g, '')`). +- Test debt closed at pipeline level: dictionary rename pipeline + (RENAME not drop+create, schema `renamed_from`), generate + pull + password warnings, pull dictionary rendering (incl. `[HIDDEN]` note), + codegen dictionary model, JS-number coercion matrix — all in + `tests/test_dictionary.py` (38 tests). +- Reviewer items accepted as-is (no code change): planner comparison + via sorted `model_dump` is order-insensitive where TS + `JSON.stringify` is key-order-sensitive — Python is strictly more + lenient, never the reverse; codepoint vs locale settings sort; + `wait_for_dictionary` quoting is safer than TS. +- Still-open e2e debt (needs live ClickHouse, consistent with prior + passes deferring docker-based e2e): `migrate-dictionary.e2e`, + `generate.e2e` dictionary flows, pull e2e, `sql-validation.e2e` + dictionary block. + +### Per-table `plugins` field (baseline gap closed in the same pass) + +- `TableDefinition.plugins: dict[str, Any] | None` + `table(plugins=...)` + kwarg — TS `TablePlugins` parity. Metadata only: ignored by the diff + engine (test in `tests/test_planner.py`), carried through + canonicalization and snapshots. Without it, a schema file ported from + TS carrying `plugins: {...}` failed Pydantic validation outright. + Consumers (backfill `timeColumn`) arrive with Phase 2. + +### Parity fixes surfaced by the docs dual-language pass (same day) + +- **Wheel packaging** — `[tool.hatch.build.targets.wheel]` only shipped + `chkit` + `chkit_plugin_obsessiondb`; a pip-installed `chkit-py` was + missing the codegen and backfill plugins entirely (the `chkit init` + template even suggests importing `chkit_plugin_codegen`). All four + packages now ship in the wheel. +- **Function-style configs (TS `ChxConfigFn`)** — the Python loader only + accepted a static `config` attribute; TS allows + `defineConfig((env) => ({...}))` with `env: {command, mode}` (documented + in the CI/CD guide). Ported: `ChxConfigEnv` model, `define_config` + accepts a callable, `load_config(path, env)` invokes it, and every CLI + command threads `ChxConfigEnv(command=...)`. Test in + `tests/test_user_config_and_config_merge.py`. + +### CLI-surface parity ports (surfaced by the docs-accuracy reviewer's live CLI probes) + +- **Plugin dispatcher flag forwarding** — `chkit plugin ` + hardcoded `flags={}`, so no plugin command could receive its own + `--flags` (Typer rejected the tokens outright). Now the `plugin` + command registers with `ignore_unknown_options`, and the dispatcher + parses forwarded tokens against the plugin command's declared flag + defs via `core.flags.parse_flags` (unknown flags error, TS-style); + remaining tokens stay positional. +- **Top-level `chkit codegen`** — existed only in TS. New + `codegen_shortcut.py` dispatches `plugin codegen codegen` with + forwarded flags (`--check`, `--out-file`, ...). Verified live: + `chkit codegen` writes, `chkit codegen --check` gates. +- **Top-level `chkit obsessiondb `** — the Python spelling was + `chkit plugin obsessiondb ` while the plugin's own runbook + strings printed the TS spelling. New `obsessiondb_shortcut.py` makes + those strings correct; multi-word commands (`service select`) flow + through as positionals. +- **Dispatcher DB connection made opportunistic** — an unreachable + ClickHouse no longer blocks plugin commands that don't need an + executor (codegen, backfill status); mirrors TS. +- **`check.failOnExtraObjects`** — TS config flag was missing from + `ChxCheckConfig`; the drift machinery already had the parameter but + both call sites hardcoded `False`. Field added (default false), + resolved, and wired through `check`/`drift`. +- **`backfill({maxChunkBytes: "10G"})`** — the factory only accepted + ints; suffix strings were CLI-flag-only. `field_validator` now + coerces via `parse_byte_size`, matching the documented + `string | number` contract. + +### Remaining gap after this pass (explicit, needs its own project) + +- ~~**Phase-2 backfill execution engine**~~ — **CLOSED** by the + 2026-08-10 Phase-2 port entry below. No remaining gap: the full + chunking + execution engine, the three upstream fixes (`f85f568`, + `3f9a246`, `9ad23f9` — ported as end-state of `main`), and the + managed-submit backend half of `c1d8d0d` are all in. Everything is at + parity as of upstream `main`. + +### Environment note + +- `.venv` was found hollow and rebuilt from `python 3.11` + + `pip install -e .[dev]`; latest ruff surfaced new lint rules + (PLR0917) on pre-existing code — annotated rather than refactored. +- `tests/test_e2e_testkit.py::test_create_run_tag_is_unique_across_calls` + is flaky (millisecond-timestamp + random-suffix collision over 100 + iterations); observed one collision, passes on re-run. Pre-existing. + + +## Main sync 2026-08-10 — Phase-2 backfill engine port (final parity gap closed) + +Full port of the chunking + execution engine and the managed-submit +backend — the last TS surface with no Python counterpart.
