Eric Hare	cc009c9133	feat(lfx): Bundle Separation and LFX Extension Framework (#13043) ... * feat(lfx): installed-package + seed-directory discovery for production install (LE-1022) Adds the read-only production install path for Modes A, B, and C of the Bundle Separation iteration. Manifest-shipping pip-installed distributions and seed-directory subdirectories are discovered at server startup and registered as Extensions at @official. * discovery.py: walks importlib.metadata.distributions() + the $LANGFLOW_SEED_DIR / /opt/langflow/bundles seed root; produces DiscoveredExtension records and typed errors for malformed manifests / configured-but-missing seed dirs. * registry.py: ExtensionRegistry service with the immutability invariant for installed and seed entries. Mutation verbs (uninstall, disable, enable, install, update_entry) all raise ExtensionImmutableError carrying the typed installed-extension-immutable / seed-directory-immutable code so the invariant is testable today; the CLI uninstall surface ships in B4. * lfx extension list: read-only inspector with text and JSON output for operators inspecting Mode B/C images. * Errors: four new typed codes (installed-extension-immutable, seed-directory-immutable, seed-directory-not-found, duplicate-extension-id) plus snapshot coverage in tests/unit/extension/test_errors.py. * Tests: 165 extension tests pass, including the LE-1022 acceptance cases -- three pip-installed wheels visible at @official, three seed bundles visible at @official, and the parametrized service-layer immutability check across every mutation verb. * Docs: docs/Deployment/deployment-extensions-production.mdx covers the Dockerfile template, k8s deployment notes, the bundle packaging convention (extension.json shipped via package-data), and troubleshooting for the typed error codes. * feat(lfx): add single-Bundle loader and LANGFLOW_COMPONENTS_PATH discovery (#12967) * feat(lfx): add extension manifest schema, validate CLI, and error formatter (LE-1014) Foundation for the Bundle Separation iteration. Defines what a valid extension.json looks like (Pydantic models + Draft 2020-12 JSON Schema), ships the offline `lfx extension validate` command, and ships the single `format_extension_error` function that every other extension-system module will use to render structured errors. What's in lfx.extension: - `ExtensionManifest` / `BundleRef` / `LangflowCompat` Pydantic models with `extra="forbid"` so unknown fields fail loudly. Deferred fields (`services`, `routes`, `hooks`, `starter_projects`, `userConfig`) are reserved as None-only so non-null values produce a dedicated `field-deferred-in-this-milestone` error instead of a generic schema wall. `bundles` accepts a list but rejects length > 1 with `multi-bundle-deferred-in-this-milestone` (validator-enforced; the loader re-checks at install time in LE-1015). - `schema.build_schema()` + `build_schema_json()` produce the publishable artifact at schemas.langflow.org/extension/v1.json. - `ExtensionError` typed envelope and `format_extension_error` -- one branch per discriminant. Codes are registered in `ERROR_CODES`; an `ExtensionError` constructed with an unknown code raises at construction time, preventing producers from shipping without a matching renderer. - `validate_extension` runs four passes: manifest discovery + schema, path-safety (no `..`, no absolute paths, no symlink escape), AST inspection of every `.py` (syntax, Component subclass present, build() declared, top-level `import *`, top-level I/O primitives), and an opt-in `--execute-imports` that runs each module in a subprocess with a temporary HOME / TMPDIR / LANGFLOW_CONFIG_DIR and LANGFLOW_*/LFX_* env vars stripped. - `lfx extension validate` and `lfx extension schema` typer subcommands. Acceptance-criteria coverage in tests/unit/extension/: - Round-trips every v0 manifest field; deferred fields rejected; multi-bundle rejected with the dedicated discriminant. - JSON Schema validates the v0 example and rejects 12 malformed manifests with distinct error paths (>= 10 required by the ticket). - Median default-validate runtime < 100ms on the basic template. - Crafted side-effect bundle: default validate does NOT execute it (canary file is never written); `--execute-imports` DOES execute it and the canary appears, while LANGFLOW_* env vars are NOT inherited by the subprocess. - Snapshot tests for every code in ERROR_CODES; a guard test verifies ERROR_CODES and the snapshot table are in lockstep so future additions cannot ship without a format branch and a snapshot. Wiring: `lfx extension` is a sub-app under the Authoring help panel so future tickets (LE-1016 init/dev, LE-1018 reload) can attach without colliding with the existing `lfx validate` (which validates flow JSON, not extensions). * fix(lfx): fall back to tomli on Python 3.10 in extension manifest loader tomllib is stdlib only on 3.11+, but lfx supports 3.10-3.13. Use the existing tomli runtime dependency as the 3.10 fallback (same API, so the import alias keeps the rest of the module unchanged). Fixes ModuleNotFoundError seen in CI on the 3.10 job. * Update src/lfx/tests/unit/extension/test_schema.py Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update src/lfx/src/lfx/extension/schema.py Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update src/lfx/src/lfx/cli/_extension_commands.py Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * feat(lfx): add single-Bundle loader and LANGFLOW_COMPONENTS_PATH discovery (LE-1015) Introduces lfx.extension.loader: the runtime that turns an Extension on disk into LoadedComponent records keyed by ext:<bundle>:<Class>@<slot>. Two paths in: - load_extension(root): one manifest, one Bundle, registered at @official. Re-checks multi-bundle at runtime (defense-in-depth vs. the schema). - discover_inline_bundles(paths): each subfolder of LANGFLOW_COMPONENTS_PATH is a Bundle at @extra. Walk order is platform-independent (sorted dirs, user-declared path order). First-wins on duplicate names; second emits duplicate-inline-bundle warning that names both paths. Manifest-first precedence helpers (installed_extension_roots, manifest_owning_distributions, filter_plugin_entry_points) let callers of the legacy langflow.plugins entry-point loader skip distributions that ship a manifest, so component entry-points are not double-registered. New typed error codes: module-import-failed, duplicate-component-name, duplicate-distribution, duplicate-inline-bundle, inline-bundle-name-invalid. Each ships with a format branch and a snapshot test. Tests cover the AC: single-bundle happy path, multi-bundle rejection, missing/empty/no-Component bundle, duplicate class names, deterministic walk order, recursive discovery, inline-bundle first-wins + dot-dir skip + bundle.json metadata, manifest-first precedence partition, PEP-503 distribution-name canonicalization. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(lfx): address LE-1015 review feedback - Drop the unproduced duplicate-distribution error code; LE-1022 will add it once startup-time discovery has a place to surface it. Restores the invariant that every code in ERROR_CODES has a producer. - Clarify that intra-bundle relative imports are NOT supported in v0; only absolute references between bundle modules work in this milestone. - Use strict=False when re-resolving bundle_root in the walker; the path was already existence-checked, and a concurrent removal in the narrow window should not raise across the loader's public boundary. - Hoist the json import out of _read_inline_bundle_json's body. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * refactor(lfx): split extension loader into a small subpackage (LE-1015) Addresses the file-size feedback from the LE-1015 review. The single 870-line loader.py becomes a flat package keyed off the four section banners that already existed inline: loader/ __init__.py # re-exports the public surface _types.py # SLOT constants, LoadedComponent, LoadResult _discovery.py # filesystem walk + importlib.util orchestration _detection.py # Component subclass identification (MRO heuristic) _orchestrator.py # load_extension, discover_inline_bundles _plugins.py # manifest-first precedence over langflow.plugins Largest file is now _orchestrator.py at 440 LOC (was 870); every file is well under the 800-LOC project guideline. No behavior change: the public import paths from lfx.extension are unchanged, all 38 loader tests still pass. ``_canonicalize_distribution`` is now exported as ``canonicalize_distribution`` from ``loader._plugins`` (it's a stable PEP-503 helper that downstream modules will reach for, so it loses the private underscore). The test suite is split to mirror the package: tests/unit/extension/loader/ conftest.py # shared fixtures, FakeDist, autouse scrub test_load_extension.py # @official slot, identity, failure modes test_inline_bundles.py # LANGFLOW_COMPONENTS_PATH, @extra slot test_plugins.py # manifest-first precedence helpers test_types.py # LoadedComponent, LoadResult, code parity Each test file imports its own slice of the public API and pulls fixtures from conftest, so a reader looking at one banner can read it in isolation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix: LangflowCompat -> LfxCompat * fix: Remove references to ticket * fix: encode maxItems constraint in schema * fix: deferred fields and schema version * Fix ruff errors * fix: align loader tests with renamed manifest API and strip ticket refs The merge of feat/extension-validate brought in the LfxCompat / compat rename, but the loader test fixtures still used LangflowCompat / bundle_api and failed at the manifest layer. Update conftest.py + test_load_extension.py to the post-rename API. Strip 17 LE-XXXX ticket references from loader source files, errors.py loader-specific comments, and the four loader test docstrings, matching the convention applied to LE-1014. Descriptive prose preserved. Promote _BUNDLE_NAME_RE to BUNDLE_NAME_RE on the manifest module so the loader's orchestrator no longer reaches across modules into a private name. * refactor(lfx): clarify broad except, log malformed bundle.json, expand test docstring - Document why _discovery.import_bundle_module catches BaseException (startup-time loader, must surface bad bundles as typed errors rather than abort). - Add debug-level logging when bundle.json is malformed or non-object so a stale-cache footgun is at least observable. - Expand test_skips_re_imported_class docstring so future maintainers don't accidentally weaken the __module__-equality guard if package-style relative imports get added later. Also drops the stale duplicate-distribution claim from the PR description; that code is correctly deferred to LE-1022 along with /all integration. * feat(lfx): wire Extension System into /all, pathsep-split LANGFLOW_COMPONENTS_PATH, emit duplicate-distribution Closes the four AC gaps the previous reviewer flagged on PR #12967: 1. /all integration: get_and_cache_all_types_dict now also calls a new import_extension_components() that loads installed Extensions via load_installed_extensions, loads inline bundles via discover_inline_bundles, and builds frontend-node templates with extension/bundle/extension_version fields stamped on. Failures are logged and skipped per bundle. 2. LANGFLOW_COMPONENTS_PATH is now split on os.pathsep so multi-entry env vars (e.g. /a:/b on POSIX) produce multiple components-path entries instead of one literal non-existent path. Empty segments and missing paths are skipped. 3. duplicate-distribution is a real producer: load_installed_extensions surfaces a typed warning on the winner LoadResult when two distributions share a canonical name, naming every involved manifest path. 4. Manifest-first precedence runtime wiring: new filter_component_entry_points loads each entry-point and only skips ones that resolve to a Component subclass on a manifest-shipping distribution. plugin_routes.load_plugin_routes now applies it so non-component entry-points (route registrars) keep loading per the AC's 'unaffected' promise. Added the previously-missing AC test for same-distribution component+non-component partition. Also makes _distribution_canonical_name defensive against MagicMock test seams. * fix(lfx): register extension components under namespaced ID; promote duplicate-distribution to error Addresses the latest review of PR #12967: P1: /all integration now keys the cache inner dict by LoadedComponent.namespaced_id (ext:<bundle>:<Class>@<slot>) rather than the bare class name. Templates also carry the namespaced_id as an explicit field so consumers that look at the value (not the key) still see the canonical address. This is the form the LE-1020 migration table will rewrite legacy class-name references to. P2: load_installed_extensions now appends duplicate-distribution to result.errors instead of result.warnings, so LoadResult.ok=False when two distributions share a canonical name. The winner's components still appear in result.components so flows already pinned to them keep working; only the conflict status changes. Updated test to assert errors + ok=False; added explicit assertion that the winner's components are still present. * fix(lfx): installed-distribution discovery accepts pyproject.toml manifest form Closes the latest review finding on PR #12967: the installed-distribution scan only looked for extension.json, ignoring distributions whose manifest lives in [tool.langflow.extension] inside pyproject.toml. The AC explicitly treats both as valid manifest forms. _distribution_manifest_path now: - Returns extension.json immediately when present (preserves precedence matching load_manifest's discovery order). - Falls back to pyproject.toml only when extension.json is absent AND the pyproject's [tool.langflow.extension] section is parseable. Validation reuses load_manifest itself so the rule lives in exactly one place; a stray pyproject.toml without the section is correctly ignored. Tests cover: pyproject-only discovery, pyproject-without-section ignored, extension.json wins on collision, end-to-end pyproject load at @official, and pyproject-form manifest-first entry-point suppression. * refactor(lfx): tighten loader invariants, surface silent skips, harden tests Addresses the latest review feedback on PR #12967: Type-level invariants (_types.py): - LoadedComponent.__post_init__ enforces that @extra components must NOT carry a distribution. The reverse (@official without distribution) is permitted because load_extension is also used for dev-mode loads against a working tree before pip install. - LoadResult docstring documents the partial-success contract: components may be non-empty when errors is non-empty (some files imported, others failed). Callers branching on ok get strict success. Silent-failure fixes (_orchestrator.py + settings/base.py): - inline-path-missing: a non-existent / non-dir LANGFLOW_COMPONENTS_PATH entry now produces a typed warning per skipped path so a typo no longer yields zero diagnostics. Settings-layer skip bumped from debug to warning for the same reason. - bundle-json-invalid: a malformed or non-object bundle.json now surfaces a typed warning instead of silently rewriting the user-declared id/version to derived values under the same bundle name. - no-component-subclass gating uses a call-local counter instead of result.errors so the diagnostic stays accurate when a future caller reuses a LoadResult (multi-bundle / batch wrapper scenarios). Test hardening: - test_re_imported_class_is_skipped_via_module_filter rewritten to actually exercise the __module__-equality check via sys.modules injection; previously passed via module-import-failed (relative-import failure), which would silently weaken if package registration changes. - test_user_declared_path_order_is_preserved: AC #8's multi-path order case (distinct bundles in [path_b, path_a]) was unasserted; added. - test_inline_module_import_failure_attributes_identity: AC #10's identity-on-partial-failure was covered for @official but not @extra; added. - test_uses_real_distributions_by_default tightened to assert ep placement (in kept, not in skipped) instead of exact-list equality, so a future Langflow-shipped manifest doesn't silently flip the assertion. bumped 64 -> 175 passing extension tests; 20 backend integration tests still pass. * fix(lfx): malformed pyproject manifests surface manifest-invalid instead of disappearing Closes the latest review finding on PR #12967: a pyproject.toml with a [tool.langflow.extension] section that has missing/invalid required fields was silently dropped because _pyproject_has_extension_section ran full schema validation via load_manifest and returned False on ValueError/TypeError. That conflated 'no section' with 'section malformed'. Fix: detect section presence only. _pyproject_has_extension_section now calls _read_pyproject_extension (TOML parse + key lookup, no schema check). Behavior: - Section absent or pyproject TOML unparseable -> False (treat as regular non-manifest package). - Section present and is a table (valid OR schema-invalid) -> True. - Section present but is not a table -> True; the author intended to declare an extension and load_extension will surface the typed error. This way a typo'd pyproject Extension produces a typed manifest-invalid LoadResult with extension_id attribution, and manifest-first precedence still suppresses its legacy component entry-points -- matching the 'typed load results on success/failure' contract for the supported pyproject manifest form. Tests: two new cases pin the behavior. test_malformed_pyproject_section_ surfaces_manifest_invalid asserts a typed load-failure result with distribution attribution; the second test pins manifest-first suppression for malformed pyproject distributions. * refactor(lfx): emit inline-path-unreadable, document reload contract, trim rot Closes the remaining nits on PR #12967: - inline-path-unreadable (new typed error code): a configured LANGFLOW_COMPONENTS_PATH entry that raises OSError on iterdir (typically permission-denied) now produces a typed LoadResult error carrying str(exc) instead of silently swallowing the message. - duplicate-inline-bundle hint trimmed: removed forward promise about hard-error-in-a-later-release; same actionability, no expiration. - discover_inline_bundles docstring trimmed from three paragraphs to two sentences (per CLAUDE.md anti-multi-paragraph rule). - _distribution_manifest_path docstring trimmed to one-liner. - installed_extension_roots dropped Used-by caller-narration list; manifest_owning_distributions docstring rewritten to call out the shadow-load risk for direct callers and point to load_installed_ extensions for the typed warning surface. - _discovery.import_bundle_module: replaced 'until that lands in a later milestone' rot with a single line ('Absolute imports only between bundle modules; relative imports unsupported.') AND added the single-load-per-process contract note documenting why LE-1018 reload must scrub registry/sys.modules before re-invoking the loader. - load_extension docstring grew a 'Single-load-per-process contract' block telling direct callers not to rely on this function for refresh. Tests: new test_unreadable_path_emits_inline_path_unreadable pins the OSError -> typed-error path. --------- Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(lfx): atomic-swap Bundle reload pipeline + endpoint + CLI (LE-1018) (#12979) * feat(lfx): add single-Bundle loader and LANGFLOW_COMPONENTS_PATH discovery (LE-1015) Introduces lfx.extension.loader: the runtime that turns an Extension on disk into LoadedComponent records keyed by ext:<bundle>:<Class>@<slot>.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(lfx): atomic-swap Bundle reload pipeline + endpoint + CLI (LE-1018) Five-stage reload (parallel staging load -> validate -> swap under write lock -> cleanup -> emit) for installed Bundles in Mode A. In-flight flows keep the pre-swap class via existing references; new flows pick up the post-swap class atomically; concurrent reloads on the same Bundle are rejected with reload-in-progress. Adds: * lfx/extension/registry.py -- BundleRegistry with per-bundle reload-in-progress guard and components_index.json writer * lfx/extension/reload.py -- the five-stage pipeline; events emission is stubbed (TODO LE-1017) so the swap mechanics can ship before the events service lands * loader: optional module_namespace param so Stage 1 lands in __reload_staging__.<id> instead of the live _lfx_ext.* namespace * errors: four new typed reload codes (reload-in-progress, reload-bundle-not-installed, reload-bundle-name-mismatch, reload-source-missing) with branch templates and snapshot tests * HTTP: POST /api/v1/extensions/{id}/bundles/{name}/reload, gated by the existing get_current_active_user dependency, returns 409 with a typed body for the in-progress collision case * CLI: lfx extension reload <id> [--bundle <name>] -- HTTP client against the dev server with text/json output and proper exit codes (--all is gated until LE-1019 lands the list endpoint) * tests: 16 reload-pipeline tests covering the AC matrix (rename round-trip, broken-bundle isolation, concurrent readers, in-flight flow, double-reload guard, bundle-name mismatch) plus 9 CLI client tests Mode A only. In Mode B/C bundle changes require a Docker image rebuild and the reload path is not exercised. The events emission in Stage 5 is intentionally stubbed -- the LE-1017 ticket will swap the body of _emit_bundle_reload_event in one place without touching the pipeline core. --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * [autofix.ci] apply automated fixes * feat(lfx): add `extension init` and `extension dev` CLIs (LE-1016) (#12968) * feat(lfx): add extension manifest schema, validate CLI, and error formatter (LE-1014) Foundation for the Bundle Separation iteration.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(lfx): add `extension init` and `extension dev` CLIs (LE-1016) The two scaffolding CLIs an Extension author types: - `lfx extension init <target>` writes the basic single-Bundle template (manifest with $schema, README, .gitignore, one Component subclass + a pytest smoke test). AC #1: the generated extension validates clean against LE-1014. AC #2: the generated test file is a valid pytest module that exercises the component's build() method. AC #3: any --template other than 'basic' fails with a typed template-deferred-in-this-milestone error and a non-zero exit. Refuses to scaffold over a non-empty target dir. - `lfx extension dev <target>` validates the local extension, records its absolute path in <config_dir>/extensions/dev_extensions.json, prints reload instructions, and execs `langflow run` (or `python -m langflow` when langflow isn't on PATH). --skip-launch registers without launching (used by tests + external dev-server scripts); --skip-validate lets authors register a known-broken manifest to debug it under the loader. Stack: - Wave 0: error codes (extension-target-exists, extension-target-invalid, local-extension-missing) with format branches and snapshot tests. - Wave 1: lfx.extension.init_template -- pure-data scaffolder, no Typer dependency so the CLI is a thin shell over it. - Wave 1: lfx.extension.dev_registry -- atomic JSON state file under the langflow user-cache dir; helpers for register / list / unregister / load_dev_extensions / dev_extension_component_paths. - Wave 2: lfx.cli._extension_commands gains init/dev subcommands. - Wave 2: langflow.main lifespan hook reads the dev registry after bundle loading and extends components_path with each registered bundle dir, so the existing palette discovery picks up dev extensions. Missing paths surface as local-extension-missing warnings (AC #5) without aborting startup. Tests (84 new, 197 total in tests/unit/extension/): - test_init_template.py: AC scenarios + identifier derivation + deterministic file shape. - test_dev_registry.py: register/list/unregister round-trip, idempotent re-register refreshes timestamp, malformed state file treated as empty, missing-path warning, recovery when path reappears, env-var override precedence. - test_cli.py: AC #1 init->validate, AC #3 deferred templates, --skip-launch registers without launching, --skip-validate short-circuits the pre-flight pass. - test_errors.py: snapshot rows for all three new codes; the every-known-code-has-a-snapshot test enforces parity. LE-1018 (reload) reuses load_dev_extensions; LE-1022 (installed-pkg discovery) shares the components_path extension pattern. AC #4 ("boots Langflow with the extension visible in the palette within 5s") is delivered jointly by `extension dev` (registers + execs) and the lifespan hook (loads on startup). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(lfx): address LE-1016 review feedback Fixes the four HIGH issues + the elevated LOW from the review pass: 1. dev_extension_component_paths now forwards EVERY warning, not just local-extension-missing. Previously a duplicate-component-name (or any future warning code) was silently dropped, hiding real signal from the lifespan hook's logs. 2. Defensive emit when a LoadResult has components but source_path is None. The current loader always sets source_path, but a future hand-built LoadResult could violate that contract; we now surface a typed local-extension-missing error rather than dropping the extension silently. 3. Replaced the fragile ``min(len(parts))`` bundle-root selection with a relative-to-source-path measurement. Handles deep-vs-shallow sibling extensions correctly without depending on absolute path depth. 4. Generated README now documents the langflow/lfx prerequisite under the Develop section so authors know `pytest` requires the lfx environment, not just Python. 5. Forced LANGFLOW_LAZY_LOAD_COMPONENTS=false unconditionally in the `extension dev` exec env (was setdefault, which let a developer's global lazy-loading export silently hide their dev components from the palette and miss AC #4's 5s budget). Plus three MEDIUMs: - sys.modules cleanup in test_generated_test_file_runs_against_generated_component so a later test importing the same dotted path doesn't pick up a stale module from a deleted tmp_path. Component instantiation moved inside the try block because Component.__init__ uses inspect.getsourcefile against self.__class__'s still-live module. - Added regex-drift test that pins the init_template patterns to match manifest.py's so a schema regex change can't quietly produce invalid scaffolded manifests. - Added two new dev_registry tests covering the forward-all-warnings contract and the source_path=None defense. Tests: 201 passing (4 new); ruff check + format clean.

Update conftest.py + test_load_extension.py to the post-rename API. Strip 17 LE-XXXX ticket references from loader source files, errors.py loader-specific comments, and the four loader test docstrings, matching the convention applied to LE-1014. Descriptive prose preserved. Promote _BUNDLE_NAME_RE to BUNDLE_NAME_RE on the manifest module so the loader's orchestrator no longer reaches across modules into a private name. * fix(lfx): align init template with renamed manifest API After merging feat/extension-loader into this branch, two surfaces fell out of sync with the renamed manifest schema: - init_template generates extension.json with `lfx: {bundle_api: [1]}`, but the validator now requires `lfx: {compat: ["1"]}` per LfxCompat. This made `test_basic_template_validates_clean` fail with manifest-invalid (`lfx.compat: Field required; lfx.bundle_api: Extra inputs are not permitted`). - test_init_template_regexes_match_manifest_schema reads `manifest_mod._BUNDLE_NAME_RE`, but that symbol was promoted to public `BUNDLE_NAME_RE` in c63f84a591. Update the test to reference the public name; init_template's local copy is still private since it also covers `_EXTENSION_ID_RE`, which remains private upstream. --------- Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(lfx): append-only migration table + flow deserializer rewrite hook (#13024) * feat(lfx): add extension manifest schema, validate CLI, and error formatter (LE-1014) Foundation for the Bundle Separation iteration.

Codes are registered in `ERROR_CODES`; an `ExtensionError` constructed with an unknown code raises at construction time, preventing producers from shipping without a matching renderer. - `validate_extension` runs four passes: manifest discovery + schema, path-safety (no `..`, no absolute paths, no symlink escape), AST inspection of every `.py` (syntax, Component subclass present, build() declared, top-level `import *`, top-level I/O primitives), and an opt-in `--execute-imports` that runs each module in a subprocess with a temporary HOME / TMPDIR / LANGFLOW_CONFIG_DIR and LANGFLOW_*/LFX_* env vars stripped. - `lfx extension validate` and `lfx extension schema` typer subcommands. Acceptance-criteria coverage in tests/unit/extension/: - Round-trips every v0 manifest field; deferred fields rejected; multi-bundle rejected with the dedicated discriminant. - JSON Schema validates the v0 example and rejects 12 malformed manifests with distinct error paths (>= 10 required by the ticket). - Median default-validate runtime < 100ms on the basic template. - Crafted side-effect bundle: default validate does NOT execute it (canary file is never written); `--execute-imports` DOES execute it and the canary appears, while LANGFLOW_* env vars are NOT inherited by the subprocess. - Snapshot tests for every code in ERROR_CODES; a guard test verifies ERROR_CODES and the snapshot table are in lockstep so future additions cannot ship without a format branch and a snapshot.

Re-checks multi-bundle at runtime (defense-in-depth vs. the schema). - discover_inline_bundles(paths): each subfolder of LANGFLOW_COMPONENTS_PATH is a Bundle at @extra. Walk order is platform-independent (sorted dirs, user-declared path order). First-wins on duplicate names; second emits duplicate-inline-bundle warning that names both paths.

What landed: * lfx.extension.migration.schema -- Pydantic models for MigrationEntry + MigrationTable with per-entry validators (exactly one of bare/import/slot populated; canonical target shape) and table-level uniqueness check. * lfx.extension.migration.loader -- canonical in-repo path, threadsafe process-lifetime cache, typed errors on every failure mode. * lfx.extension.migration.rewrite -- node-by-node rewrite, idempotent on canonical refs, difflib-backed closest-match suggestion for unmapped references, cross-bucket ambiguity surfaces component-name-ambiguous instead of silently loading into the wrong bundle. * Wired into Graph.from_payload before validate_flow_for_current_settings so every saved-flow load goes through migration first. * scripts/migrate/check_migration_append_only.py -- CI guard that diffs the working-tree table against origin/main and rejects removals or target mutations; reordering and additions are allowed. * 34 new unit tests covering rewrite paths, loader failure modes, schema invariants, and the CI script behavior. What is deliberately deferred: * flow-migrated event emission. The events pipeline is unavailable in this iteration; the wiring point in Graph.from_payload is marked TODO and the MigrationReport already carries every field a future emitter needs.

In-flight flows keep the pre-swap class via existing references; new flows pick up the post-swap class atomically; concurrent reloads on the same Bundle are rejected with reload-in-progress. Adds: * lfx/extension/registry.py -- BundleRegistry with per-bundle reload-in-progress guard and components_index.json writer * lfx/extension/reload.py -- the five-stage pipeline; events emission is stubbed (TODO LE-1017) so the swap mechanics can ship before the events service lands * loader: optional module_namespace param so Stage 1 lands in __reload_staging__.<id> instead of the live _lfx_ext.* namespace * errors: four new typed reload codes (reload-in-progress, reload-bundle-not-installed, reload-bundle-name-mismatch, reload-source-missing) with branch templates and snapshot tests * HTTP: POST /api/v1/extensions/{id}/bundles/{name}/reload, gated by the existing get_current_active_user dependency, returns 409 with a typed body for the in-progress collision case * CLI: lfx extension reload <id> [--bundle <name>] -- HTTP client against the dev server with text/json output and proper exit codes (--all is gated until LE-1019 lands the list endpoint) * tests: 16 reload-pipeline tests covering the AC matrix (rename round-trip, broken-bundle isolation, concurrent readers, in-flight flow, double-reload guard, bundle-name mismatch) plus 9 CLI client tests Mode A only. In Mode B/C bundle changes require a Docker image rebuild and the reload path is not exercised. The events emission in Stage 5 is intentionally stubbed -- the LE-1017 ticket will swap the body of _emit_bundle_reload_event in one place without touching the pipeline core. * feat(frontend): palette Bundle reload action + loading + toasts Adds the frontend half of the bundle reload flow. When the Bundle header is right-clicked or its overflow ("⋮") icon clicked, a Reload action fires POST /api/v1/extensions/{id}/bundles/{name}/reload and surfaces the result via the existing alert-store toast system. What landed (frontend only): * src/controllers/API/queries/extensions/ -- typed wire-format models (ReloadBundleResponse, ExtensionErrorPayload, ReloadInProgressDetail) and the useReloadBundle mutation hook. The hook unwraps the 409 `reload-in-progress` detail into a stable, parseable Error message so the UI can branch without reading status codes. * components/bundleHeaderActions.tsx -- new Select-based overflow menu next to the Bundle header chevron. Three toast paths: success (green, with components +/- delta), structural failure (red, with typed errors and inline hints), reload-in-progress (notice). Loading state swaps the kebab icon for a spinning Loader2 while the request is in flight. Renders nothing when no extension_id is on the bundle, so the static SIDEBAR_BUNDLES list is unaffected. * components/bundleItems.tsx -- wires the new actions in next to the chevron, plus a context-menu (right-click) capture that opens the same overflow trigger so keyboard / mouse / right-click all share one source of truth. * types/index.ts -- BundleItemProps.item gains an optional extension_id; took the opportunity to extract the SidebarBundle interface and tighten three pre-existing `any` types. * customization/feature-flags.ts -- ENABLE_EXTENSION_RELOAD gate, off by default until the bundle-list endpoint that populates extension_id per bundle ships. * controllers/API/helpers/constants.ts -- EXTENSIONS URL constant. * Tests: 7 component tests + 3 mutation-hook tests, all green. Total sidebar + extensions test count: 479 passing. Deferred: * Event-pipeline subscription is left as an inline TODO. The mutation response carries enough information to drive the toasts on its own today; once the events service lands the toast wiring will move to a `bundle_reloaded` / `bundle_reload_failed` listener so multi-tab and multi-worker swaps surface exactly once.

The Docker builders ran ``uv sync --no-install-project`` after copying only the top-level pyproject.toml files, so resolution failed with ``Distribution not found at: file:///app/src/bundles/<name>``.

Detect editable mode via direct_url.json's PEP 660 marker and fall through to walking the source tree; non-editable wheel installs still exercise the dist.files path the loader uses at runtime. * chore: auto-bake note keys and regenerate backend locales/en.json [skip ci] * fix(docker): copy src/bundles before uv sync so workspace bundles resolve Each directory under ``src/bundles`` is a uv workspace member referenced by ``langflow-base`` (and the root project) as a path dependency. The Docker builders ran ``uv sync --no-install-project`` after copying only the top-level pyproject.toml files, so resolution failed with ``Distribution not found at: file:///app/src/bundles/<name>``. Copying the whole ``src/bundles`` tree (rather than enumerating each bundle) means a new bundle dropped under that dir does not require a Dockerfile edit. The full ``./src`` copy a few lines later produces the same final layer either way; this earlier copy just unblocks the dependency-resolution sync. Touched all builders that run a workspace-resolving uv sync: * docker/build_and_push.Dockerfile * docker/build_and_push_base.Dockerfile * docker/build_and_push_ep.Dockerfile * docker/build_and_push_with_extras.Dockerfile * docker/dev.Dockerfile (bind-mount instead of COPY) --------- Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com> * fix: Review sweep * fix: More review comments addressed * Ruff check * docs: add bundle porting guide Step-by-step recipe for extracting a provider package from the in-tree ``src/lfx/src/lfx/components/<provider>/`` directory into a standalone Extension Bundle distribution under ``src/bundles/<provider>/``. The DuckDuckGo bundle is the reference; every section maps to a single copy-pasteable change and a verification command. Doc surfaces a forthcoming ``scripts/migrate/port_bundle.py`` automation helper for the mechanical bits; that script lands on the next branch together with the second-pilot port that validates the recipe end-to-end. * fix(extension): accept Output(method=...) in build-method validator The validator's static AST check looked for a literal ``build`` method on every Component subclass and emitted ``build-method-missing`` when absent. Real Langflow components -- including the production ``DuckDuckGoSearchComponent`` and the in-tree ``ArXivComponent`` -- do not declare a literal ``build``; they declare entry-points declaratively via ``outputs = [Output(name=..., method=<name>)]`` and the named method is what gets called. Result: every clean port hit a spurious ``build-method-missing`` error from ``lfx extension validate``. Fix: extend ``_has_build_method`` to also accept any class that names a method via ``Output(method="X")`` AND defines that method in the class body. The negative case ("Output(method=...) without a matching def") still fires -- a typo'd method name would crash at runtime, so the static check should keep flagging it. Two new tests in ``test_validate.py`` lock the contract: positive case mirroring duckduckgo / arxiv, negative case for typo'd method names. All 26 validator tests pass. PORTING.md updates fall out of running the recipe live against the duckduckgo bundle on this branch: * Validate path is ``src/bundles/<bundle>/src/lfx_<bundle>``, not the bundle root (the manifest lives next to ``__init__.py``). * Index regen needs ``LFX_DEV=1`` to skip the prebuilt-index fast path and uses ``scripts/build_component_index.py``. * Drop the migration-table JSON from the ruff invocation (ruff treats it as Python and complains about the top-level expression). * fix: Delete outdated components * fix(palette): wire reload kebab via DropdownMenu, not Select The reload kebab on the palette Bundle header was using Radix ``Select`` to back its overflow menu. ``Select`` is for picking a value, not for firing an action: ``onValueChange`` is gated by value-equality (so a re-click of the only item is a no-op), and the popover-portal click semantics interact poorly with the parent disclosure-trigger button. The combined effect: clicking ⋮ → Reload opened the popover and closed it, but never fired the network request, with no console error to point at. Switch to ``DropdownMenu`` (purpose-built action menu). ``DropdownMenuItem`` exposes ``onSelect`` which fires on every activation -- the same callback path keyboard navigation uses -- so clicking Reload reliably invokes the mutation. Test mocks updated to drive the DropdownMenu primitives instead of Select; all 8 bundleHeaderActions tests + the broader 437-test sidebar suite still pass. * fix(extension): route ddgs through the lockfile + drop bogus list endpoint hint Two reviewer findings, both about reproducibility / correctness of operator-facing surfaces. [P2] ``docker/build_and_push_base.Dockerfile`` previously installed ``ddgs`` via an unpinned ``uv pip install ddgs`` after the workspace sync. That made the base image non-reproducible: a future ``ddgs`` release would silently drift from the tested lock state on every rebuild. Fix: route ddgs through the locked sync. * Restore the ``duckduckgo`` extra in ``src/backend/base/pyproject.toml`` (``ddgs>=9.0.0``) as an internal "image-build sidecar". Public consumers still install ``lfx-duckduckgo`` directly; the extra exists only to keep ``ddgs`` resolved in the lockfile. * The Dockerfile now passes ``--extra duckduckgo`` to ``uv sync --frozen``, picking up the locked ``ddgs==9.14.1``. * The follow-on bundle install keeps ``--no-deps`` so it does not duplicate the now-locked ``ddgs`` / ``lfx`` / ``langchain-community``. [P3] ``langflow/api/v1/extensions.py`` returned a fix hint that pointed operators at ``GET /api/v1/extensions`` -- a route that does not exist in this PR (it lands with the LE-1019 list endpoint). Replaced with a reference to ``lfx extension list``, which is shipped here. * fix(compat): bridge langflow.components.* dynamically via meta path finder Commit 45552cd1df ("fix: Delete outdated components") removed the physical shim files under ``src/backend/base/langflow/components/`` that forwarded saved-flow imports like ``from langflow.components.processing.converter import convert_to_dataframe`` or ``import langflow.components.knowledge_bases.retrieval`` to their new ``lfx.components.*`` homes. Without those shims, dotted imports into ``langflow.components.<sub>.<leaf>`` failed at flow-load time -- the existing ``LangflowCompatibilityModule`` registers ``langflow.components`` itself in ``sys.modules`` but does not bridge submodules, so Python's import machinery falls through to the now-empty langflow.components directory and raises ``ModuleNotFoundError``. Replace the deleted physical-shim stack with a single ``MetaPathFinder`` in ``langflow/__init__.py`` that dynamically resolves every ``langflow.components.<rest>`` import to ``lfx.components.<rest>`` and registers the loaded lfx module in ``sys.modules`` under both names. The langflow- and lfx-prefixed imports share a single underlying module object, so class identity is preserved across the bridge -- ``isinstance`` checks against types resolved through either path keep working. The finder also carries a small first-segment override map for the few subpackages whose name diverged during the move; the only entry today is ``knowledge_bases`` -> ``files_and_knowledge``, matching the deleted shim's intent. Why a meta finder instead of restoring the physical shim files (option 1 from the scope analysis): the meta finder scales without per-bundle maintenance. Every future bundle extraction landed under ``lfx.components`` becomes reachable via the legacy ``langflow.components.<bundle>`` path immediately; nobody has to remember to add a parallel langflow shim. Six new unit tests in ``test_langflow_components_compat_shim.py`` lock the contract: dotted submodule resolution, helpers re-export, the ``knowledge_bases`` override, class identity preservation, top-level aliasing, and the "arbitrary extracted bundle" case that prevents regression for future ports. Verified pre-existing tests: * 17 dynamic-import integration tests pass. * The reload-route-guard suite still passes. * The Research Translation Loop starter-project test (which loads ArXivComponent) passes. * Update index.tsx * fix: Review pass on delivery * fix: Second review sweep, bare names * fix: Third review sweep * Resolve dotted imports and attribute chains Record import shape and flatten attribute chains so router references can be resolved across dotted imports and re-exports. Added ImportTarget dataclass, _attribute_chain helper, and switched IncludeCall/DecoratorRef to store attribute tuples. parse_file now records ImportTarget entries for imports and captures dotted parent/child chains for include_router and decorators. Replaced _resolve_var with _resolve_chain which handles "from" vs "module" imports, various import shapes (including import x.y and aliased imports), and prevents infinite recursion on re-export cycles. * One more sweep * Add seed-directory extension loading and docs Introduce filesystem "seed directory" extension support and authoring docs. Adds three documentation pages (quickstart, manifest reference, author guide) and wires them into the docs sidebar. Implement load_seed_extensions to discover/load bundles from $LANGFLOW_SEED_DIR (default /opt/langflow/bundles), export it from loader/__init__ and extension package, and integrate it into the components import pipeline. Handle installed-vs-seed shadowing by preferring installed distributions and appending a typed seed-bundle-shadowed ExtensionError; add the corresponding error code and message. Update schema doc link and add unit/integration tests to cover seed loading, determinism, shadowing behavior, and migration-target resolution. * Fix claims * Fix docasaurus build * Clean up the manual checklist * Update test_pilot_duckduckgo_upgrade.py * fix: Some wording issues with dogfooding * fix: Comments addressed * Update port_bundle.py * Update component_index.json * chore: auto-bake note keys and regenerate backend locales/en.json [skip ci] * fix: pytest testpaths glob and accurate scaffold output in port_bundle testpaths now uses ``src/bundles/*/tests`` so future bundle tests are picked up automatically without hardcoding each bundle at the root. pytest expands the glob via ``glob.iglob(..., recursive=True)``. Rewrote port_bundle.py's ``_render_migration_entries`` and ``_render_test_scaffold`` to match the actual conventions: * Migration entries now use ``bare_class_name``/``import_path``/ ``legacy_slot`` + ``target`` + ``added_in`` (the keys ``lfx.extension.migration.loader`` actually reads) instead of the invented ``from``/``to``/``release`` shape. * Test scaffold now imports ``load_migration_table`` and ``migrate_flow_payload`` -- the APIs the real tests use -- instead of a fictitious ``resolve_legacy_id``. Includes the ``migration_table`` fixture, ``_saved_flow``/``_saved_flow_node`` helpers, and the distribution-importable + manifest-shipped checks that mirror ``test_pilot_duckduckgo_upgrade.py``. Verified by rendering the scaffold for duckduckgo with synthetic plan data, dropping it into ``src/lfx/tests/integration/extension/``, and running pytest -- ``3 passed, 2 skipped`` (skips are the wheel-only checks, by design when run inside the lfx isolation venv). * [autofix.ci] apply automated fixes * fix: Review comments * Update test_discovery.py * feat: Port Arxiv to the Extension Framework (#13047) * feat(bundles): port arxiv as the second-pilot Bundle + porting helper Validates ``src/bundles/PORTING.md`` end-to-end by following its recipe against a clean candidate (``ArXivComponent``: no third-party runtime deps, no langflow-base extra, no deactivated duplicate). Touchpoints exercised: * Bundle skeleton at ``src/bundles/arxiv/`` mirroring duckduckgo. * In-tree provider directory removed from ``src/lfx/src/lfx/components/`` along with its three references in ``components/__init__.py``. * Workspace wiring: dep, ``[tool.uv.sources]``, ``[tool.uv.workspace]`` members, lockfile. * Migration table: bare-name + two import-path forms + legacy_slot entry. * Component index regenerated via ``LFX_DEV=1`` (forces dynamic discovery; without it the script reproduces stale entries). * Integration test ``test_pilot_arxiv_upgrade.py`` mirroring the duckduckgo pilot suite; 5 tests pass against the workspace install. PORTING.md updates fall out of running the recipe live: * Validate path is ``src/bundles/<bundle>/src/lfx_<bundle>``, not the bundle root (the manifest lives next to ``__init__.py``). * Index regen needs ``LFX_DEV=1`` to skip the prebuilt-index fast path. * Drop the migration-table JSON from the ruff invocation (ruff treats it as Python and complains about the top-level expression). ``scripts/migrate/port_bundle.py`` is the mechanical helper referenced from § Automation: stdlib-only, dry-run by default, refuses on invalid input, and intentionally leaves migration-table edits + integration-test authoring to a human (release version + bare-name uniqueness require judgement). Three guard rails verified: invalid bundle name, existing-target-bundle, missing in-tree provider. * chore: auto-bake note keys and regenerate backend locales/en.json [skip ci] * Update Research Translation Loop.json * Update .secrets.baseline * fix: Move bundle test for arxiv * Update PORTING.md * Update component_index.json * chore: auto-bake note keys and regenerate backend locales/en.json [skip ci] * Update component_index.json * [autofix.ci] apply automated fixes --------- Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> * [autofix.ci] apply automated fixes * chore: auto-bake note keys and regenerate backend locales/en.json [skip ci] * Update component_index.json * Update component_index.json * Update component_index.json * fix: empty cache dict on reload * Lint fixes * Update test_components_cache_integration.py * Update test_reload.py * Hardening pass * Update test_init_template.py * fix: resolve cross-source bundle-name shadowing before registry population The reload pipeline reads ``live.source_path`` from the registry on every call. Previously, the registry-population loop in ``import_extension_components`` only special-cased installed-shadows-seed; for every other pair (seed/dev, seed/inline, dev/inline, installed/dev, installed/inline) it silently overwrote earlier records via last-wins iteration order. A stale dev registration whose ``source_path`` pointed at a different filesystem location could clobber the seed record's ``source_path``; reload would then walk the dev path while the operator edited the seed copy on disk -- producing 200 OK with empty deltas on every reload, including for syntactically broken edits. Generalize the dedup pass to every (earlier, later) pair using the explicit precedence ``installed > seed > dev > inline``, applied before both registry population AND palette template construction so the two read from the same winning source. Add a new generic ``bundle-shadowed`` typed error code for the pairs the existing ``seed-bundle-shadowed`` did not cover; keep ``seed-bundle-shadowed`` for the documented installed- over-seed pair so existing CLI exit-code logic and snapshot tests stay intact. Both codes are warn-only in ``lfx extension list``. Also add an INFO log line in reload Stage 1 with the resolved ``source_path`` so the next "200 OK with empty deltas" repro can be triaged from the server log alone -- if the path logged is not the path the operator was editing, this dedup is what to look at. Includes a regression test (``test_seed_bundle_shadows_dev_emits_generic_bundle_shadowed``) that asserts both halves: seed wins in the BundleRegistry AND the registry's ``source_path`` is the seed path, not the stale dev path. * Update component_index.json * fix: widen lfx-* bundles' requires-python to <3.15 to match langflow root The two pilot bundles (``lfx-arxiv``, ``lfx-duckduckgo``) were scaffolded by ``scripts/migrate/port_bundle.py`` whose template hard-coded ``requires-python = ">=3.10,<3.14"``. Because both bundles are uv workspace members of the langflow root, that cap leaked into every workspace-level resolve: ``cd src/lfx && uv sync`` (the path ``make lfx_tests`` takes) refuses to pick a Python 3.14 interpreter even though lfx itself, langflow, and langflow-base all advertise ``>=3.10,<3.15``. Hosts with 3.14 installed see: error: The requested interpreter resolved to Python 3.14.5, which is incompatible with the project's Python requirement: `>=3.10, <3.14`. Fix at the source so future ``port_bundle.py`` runs do not regress this: template emits ``<3.15``, and the two existing emitted pyprojects are bumped in lockstep. ``uv.lock`` regenerates with the wider range. Verified ``make lfx_tests`` resolves cleanly on a host with both 3.13.12 and 3.14.5 installed; the focused extension slice runs to completion. * Update __init__.py * Update src/lfx/tests/unit/extension/migration/test_rewrite.py Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update src/lfx/src/lfx/extension/loader/_plugins.py Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update docs/docs/Deployment/deployment-extensions-production.mdx Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update src/lfx/src/lfx/extension/loader/_orchestrator.py Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update docs/docs/Develop/extensions-author-guide.mdx Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * Update docs/docs/Develop/extensions-manifest.mdx Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> * fix: Coderabbit review suggestions * Template updates * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes * Tweaks to bundle hot reload * [autofix.ci] apply automated fixes * chore: Address review comments by @Cristhianzl * [autofix.ci] apply automated fixes * Update BUNDLE_API.md * Update component_index.json * Update component_index.json * Update Structured Data Analysis Agent.json * fix: Next round of review comments * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes --------- Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com>	2026-05-18 17:36:56 +00:00
Gabriel Luiz Freitas Almeida	1955f8fae5	chore: support Python 3.14 (#13085) ... * feat: upgrade Docker images to Python 3.14 (experimental) ## Changes - Update pyproject.toml: requires-python from <3.14 to <3.15 - Update all 5 Dockerfiles to use Python 3.14: - Builder stage: python3.12-trixie-slim → python3.14-trixie-slim - Runtime stage: python:3.12-slim-trixie → python:3.14-slim-trixie ## Files Updated - src/backend/base/pyproject.toml - docker/build_and_push_base.Dockerfile - docker/build_and_push.Dockerfile - docker/build_and_push_backend.Dockerfile - docker/build_and_push_with_extras.Dockerfile - docker/build_and_push_ep.Dockerfile ## Rationale Python 3.14.5 was released on May 10, 2026. Upgrading to the latest Python version should help reduce CVE vulnerabilities in Docker images. ## Testing Strategy This is an experimental change to test Python 3.14 compatibility: - Docker images will use Python 3.14 - CI/CD workflows still test on Python 3.10-3.13 - Nightly build will validate if dependencies work with 3.14 - Can be reverted quickly if issues are found ## Next Steps - Monitor nightly build for failures - If successful, update CI/CD workflows to add Python 3.14 to test matrix - If failures occur, revert and investigate compatibility issues * chore: support Python 3.14 Bump requires-python upper bound to <3.15 across langflow, langflow-base, lfx, and langflow-sdk, and add 3.14 to CI test matrices so PRs are gated on 3.14 compatibility. Conditional pins for transitive deps without 3.14 wheels at the existing caps: - onnxruntime: >=1.26 on 3.14 (existing <1.24 cap retained for 3.10) - faiss-cpu: >=1.13.2 on 3.14 (existing ==1.9.0.post1 retained for <3.14) * chore: marker-gate IBM watsonx packages for Python 3.14 ibm-watsonx-ai 1.3.x cannot import on Python 3.14: its StrEnum subclasses override __init__ in a way that conflicts with 3.14's reworked enum __set_name__ path (TypeError on KnowledgeBaseFieldRole class creation). Cap ibm-watsonx-ai, langchain-ibm, and the ibm-watsonx-orchestrate-* extras at python_version<'3.14' until upstream adapts. Watsonx component imports are already lazy, so this surfaces only at component-access time on 3.14, where the existing ImportError handler in lfx.components.ibm.__init__ degrades it gracefully. test_model_utils.py imports ChatWatsonx at module top to verify get_model_name resolves model_id; guard that import so the test module skips on 3.14 instead of breaking collection. * [autofix.ci] apply automated fixes * chore: upgrade remaining Docker images to Python 3.14 build_and_push*.Dockerfile already moved to 3.14 in the merge from feat/upgrade-python-3.14-docker-images. Apply the same bump to the dev, devcontainer, and lfx Docker images so all in-repo Dockerfiles share one Python version. * [autofix.ci] apply automated fixes * chore: gate 3.14-broken extras to python_version<'3.14' cuga (and its transitive fastembed -> py-rust-stemmers source build), altk/agent-lifecycle-toolkit (re-pulls ibm-watsonx-ai which was already gated), langchain-pinecone, langwatch, ragstack-ai-knowledge-store, and OpenDsStar all pin themselves below 3.14 upstream. Without a marker guard, the workspace lock still tries to install them and a Docker `uv sync` then attempts source builds that require Rust (CI Docker test failure with py-rust-stemmers 0.1.5). Add python_version<'3.14' (or <'3.13' for ragstack) to each pin so those packages are simply omitted from the 3.14 install set until upstream catches up. uv pip check is now clean on 3.14.2. * test: skip test_altk_agent on Python 3.14 altk (agent-lifecycle-toolkit) is gated to python_version<'3.14' upstream and now via the langflow-base [altk] extra marker. The test imports altk at module top to exercise ALTKAgentComponent; guard the import so collection skips on 3.14 instead of failing. * test: skip remaining altk tests on Python 3.14 Three more test modules import lfx.base.agents.altk_* at module top, which transitively imports altk. Add the same module-level skip guard as test_altk_agent.py: - test_altk_agent_logic.py - test_altk_agent_tool_conversion.py - test_conversation_context_ordering.py * fix(calculator): replace removed ast.Num with ast.Constant for Python 3.14 ast.Num was deprecated in Python 3.8 in favor of ast.Constant and removed entirely in 3.14. The calculator tool and its core walker crashed on 3.14 with 'module ast has no attribute Num'. Switch the isinstance checks to ast.Constant + isinstance(node.value, (int, float)), and drop the now-dead ast.Num backwards-compat branch in calculator_core.py (the ast.Constant branch already handles every input it would have matched). Update the parser unit-test fixtures to construct ast.Constant nodes. * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * test: skip LangWatch HTTP instrumentation tests on Python 3.14 langwatch is gated to python_version<'3.14' upstream. The TestLangWatchHttpInstrumentation class patches langwatch.setup and langwatch.trace inside a fixture, which requires langwatch to be importable; on 3.14 the test errors with ModuleNotFoundError. Guard the class with a skipif on langwatch availability. * test: allow IBM and altk components to be missing on Python 3.14 test_all_modules_importable enforces that every component in __all__ imports cleanly. On 3.14 the ibm-watsonx-ai, langchain-ibm, and altk packages are gated upstream and intentionally not installed, so the WatsonxAI, WatsonxEmbeddings, and ALTKAgent components fail to import as designed. - test_all_components_in_categories_importable: accept a known-gated deny-list on 3.14 instead of failing. - test_all_lfx_component_modules_directly_importable: extend the existing 'missing optional dependency' allowlist with altk, langchain_ibm, and ibm_watsonx_ai. * fix(lfx): pass ensure_exists to user_cache_dir for Python 3.14 Python 3.14 tightened PurePath.__init__ to reject unknown keyword arguments. The KeyedWorkerLockManager constructor was passing ensure_exists=True to Path() instead of user_cache_dir(), which silently worked on 3.10-3.13 but raises TypeError on 3.14 and also meant the cache directory was never actually being created. Move the kwarg to user_cache_dir() where it belongs and update the two unit tests that asserted the buggy call shape. * [autofix.ci] apply automated fixes * test: accept either ZIP or JSON error path on Python 3.14 Python 3.14's zipfile.is_zipfile() now validates the central-directory signature in addition to EOCD, so the garbage+EOCD payload no longer passes the is_zipfile() dispatch in the /flows/upload/ route. The endpoint still returns 400 with a descriptive detail (now from the JSON branch); only the message wording differs, which the test was asserting verbatim. * fix(lfx): normalize cors_origins ['*'] back to '*' on Python 3.14 Pydantic-settings on Python 3.14 parses the env var '*' into ['*'] before the cors_origins field validator runs (the list[str] | str union resolves differently than on 3.10-3.13). Collapse that back to the bare-string wildcard so downstream consumers — including warn_about_future_cors_changes and the test suite — see the same shape on every supported Python version. --------- Co-authored-by: vijay kumar katuri <vijay.katuri@ibm.com> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com>	2026-05-13 22:23:39 +00:00

Adam-Aghili	0732423f27	chore: security patch (#12725) ... * chore: security patch security patch * chore: upgrade package-lock.json * chore: smolagents and transformer update * chore: redis upgrade * chore: litellm upgrade * fix: Pin click to avoid lower versions ## Root cause **litellm 1.83.5+** introduced an exact pin `click==8.1.8` in its `requires_dist` (upstream bug [BerriAI/litellm#26154](https://github.com/BerriAI/litellm/issues/26154) — "Pinning exact dependency versions breaks downstream consumers"). When this branch bumped litellm to 1.83.11, uv was forced to downgrade click from 8.3.2 → 8.1.8. Click 8.2+ captures stderr separately by default; 8.1 merges it — hence `ValueError: stderr not separately captured`. ## Fix - [pyproject.toml:155](pyproject.toml:155) — added `"click>=8.3.0"` to `[tool.uv] override-dependencies` with comment linking the upstream issue. - [src/backend/base/pyproject.toml:112](src/backend/base/pyproject.toml:112) — same override so `langflow-base` Docker builds pick it up too. - Regenerated `uv.lock` (click: 8.1.8 → 8.3.3). - Patched the `click` entry in `src/backend/base/uv.lock` to 8.3.3 (that lockfile is used by `docker/build_and_push_base.Dockerfile` via `uv sync --frozen`; uv treats backend/base as a workspace member so I updated its click block directly — no other references to 8.1.8 remain). - Reverted [src/lfx/tests/unit/cli/test_run_real_flows.py](src/lfx/tests/unit/cli/test_run_real_flows.py) back to its original `result.stderr` usage — now passes cleanly with click 8.3.3. All 19 tests in the file pass. * Update build_and_push_backend.Dockerfile The `uv pip install` command doesn't read `[tool.uv] override-dependencies` from the target packages' pyproject.toml — those overrides only apply during `uv lock`/`uv sync`. The fix is to pass the overrides explicitly via `--overrides`. Now let me verify it works by running the same install locally. Resolution succeeded — click==8.3.3, aiohttp==3.13.5, litellm==1.83.11 all coexist. Let me also test without `--overrides` to confirm I reproduce the original failure. Reproduced the Docker failure locally. Now test with the overrides file: Fix verified — resolution succeeds with the overrides file, failing without. Let me clean up and show the final Dockerfile change. ## Summary **Root cause:** The Dockerfile uses `uv pip install ./src/...` which **does not read** `[tool.uv] override-dependencies` from the target packages' `pyproject.toml` — those overrides only apply during `uv lock`/`uv sync`. On Linux, `cuga>=0.2.20` requires `aiohttp>=3.13.5`, but `litellm==1.83.11` exact-pins `aiohttp==3.13.3` (same upstream bug as the click pin, [BerriAI/litellm#26154](https://github.com/BerriAI/litellm/issues/26154)). Without an active override, resolution fails. **Fix:** Write a `/tmp/uv-overrides.txt` file mirroring the workspace's `override-dependencies` (litellm, python-dotenv, openai, aiohttp, click) and pass `--overrides /tmp/uv-overrides.txt` to `uv pip install`. Verified locally by reproducing the exact failure in an isolated tmp directory (to escape the workspace's pyproject.toml auto-apply), then confirming the overrides file resolves it: - aiohttp==3.13.5 ✓ - click==8.3.3 ✓ - litellm==1.83.11 ✓ - cuga==0.2.22 ✓ * Templates version update * Update .secrets.baseline * chore: update overrides * chore: bump version * chore: bump main version * chore: bump SDK version to 0.1.1 * chore: run uv lock and uv sync after SDK version bump * chore: read the overrides from a single source security patch * chore: add pip check toggle add pip check toggle * chore: litellm base uv.lock update * fix(chore): Pin litellm back to last working release * fix(chore): Pin to 1.83 and higher litellm * Update build_and_push_backend.Dockerfile * chore: update base uv.lock * fix: lazyload toolguard since its an optional extra * Update .secrets.baseline * Update component_index.json * Rebuild component index * Update component_index.json --------- Co-authored-by: Eric Hare <ericrhare@gmail.com> Co-authored-by: vijay kumar katuri <vijay.katuri@ibm.com> (cherry picked from commit 60a8f76c3fde17124057626c671ea8162872837a)	2026-04-23 17:49:53 -07:00

Himavarsha	a3d74ee4e8	fix: Clear input fields data operations (#11773) ... * feat: Pluggable AuthService with abstract base class (#10702) (#11654) feat(auth): Pluggable AuthService with abstract base class (#10702) * feat: Introduce service registration decorator and enhance ServiceManager for pluggable service discovery - Added `register_service` decorator to allow services to self-register with the ServiceManager. - Enhanced `ServiceManager` to support multiple service discovery mechanisms, including decorator-based registration, config files, and entry points. - Implemented methods for direct service class registration and plugin discovery from various sources, improving flexibility and extensibility of service management. * feat: Implement VariableService for managing environment variables - Introduced VariableService class to handle environment variables with in-memory caching. - Added methods for getting, setting, deleting, and listing variables. - Included logging for service initialization and variable operations. - Created an __init__.py file to expose VariableService in the package namespace. * feat: Enhance LocalStorageService with Service integration and async teardown - Updated LocalStorageService to inherit from both StorageService and Service for improved functionality. - Added a name attribute for service identification. - Implemented an async teardown method for future extensibility, even though no cleanup is currently needed. - Refactored the constructor to ensure proper initialization of both parent classes. * feat: Implement telemetry service with abstract base class and minimal logging functionality - Added `BaseTelemetryService` as an abstract base class defining the interface for telemetry services. - Introduced `TelemetryService`, a lightweight implementation that logs telemetry events without sending data. - Created `__init__.py` to expose the telemetry service in the package namespace. - Ensured robust async methods for logging various telemetry events and handling exceptions. * feat: Introduce BaseTracingService and implement minimal TracingService - Added `BaseTracingService` as an abstract base class defining the interface for tracing services. - Implemented `TracingService`, a lightweight version that logs trace events without external integrations. - Included async methods for starting and ending traces, tracing components, and managing logs and outputs. - Enhanced documentation for clarity on method usage and parameters. * feat: Add unit tests for service registration decorators - Introduced a new test suite for validating the functionality of the @register_service decorator. - Implemented tests for various service types including LocalStorageService, TelemetryService, and TracingService. - Verified behavior for service registration with and without overrides, ensuring correct service management. - Included tests for custom service implementations and preservation of class functionality. - Enhanced overall test coverage for the service registration mechanism. * feat: Add comprehensive unit and integration tests for ServiceManager - Introduced a suite of unit tests covering edge cases for service registration, lifecycle management, and dependency resolution. - Implemented integration tests to validate service loading from configuration files and environment variables. - Enhanced test coverage for various service types including LocalStorageService, TelemetryService, and VariableService. - Verified behavior for service registration with and without overrides, ensuring correct service management. - Ensured robust handling of error conditions and edge cases in service creation and configuration parsing. * feat: Add unit and integration tests for minimal service implementations - Introduced comprehensive unit tests for LocalStorageService, TelemetryService, TracingService, and VariableService. - Implemented integration tests to validate the interaction between minimal services. - Ensured robust coverage for file operations, service readiness, and exception handling. - Enhanced documentation within tests for clarity on functionality and expected behavior. * docs: Add detailed documentation for pluggable services architecture and usage * feat: Add example configuration file for Langflow services * docs: Update PLUGGABLE_SERVICES.md to enhance architecture benefits section - Revised the documentation to highlight the advantages of the pluggable service system. - Replaced the migration guide with a detailed overview of features such as automatic discovery, lazy instantiation, dependency injection, and lifecycle management. - Clarified examples of service registration and improved overall documentation for better understanding. * [autofix.ci] apply automated fixes * test(services): improve variable service teardown test with public API assertions * docs(pluggable-service-layer): add docstrings for service manager and implementations * fix: remove duplicate teardown method from LocalStorageService During rebase, the teardown method was added in two locations (lines 57 and 220). Removed the duplicate at line 57, keeping the one at the end of the class (line 220) which is the more appropriate location for cleanup methods. * fix(tests): update service tests for LocalStorageService constructor changes - Add MockSessionService fixtures to test files that use ServiceManager - Update LocalStorageService test instantiation to use mock session and settings services - Fix service count assertions to account for MockSessionService in fixtures - Remove duplicate class-level clean_manager fixtures in test_edge_cases.py These changes fix test failures caused by LocalStorageService requiring session_service and settings_service parameters instead of just data_dir. * fix(services): Harden service lifecycle methods - Fixed Diamond Inheritance in LocalStorageService - Added Circular Dependency Detection in _create_service_from_class - Fixed StorageService.teardown to Have Default Implementation * docs: Update discovery order for pluggable services * fix(lfx): replace aiofile with aiofiles for CI compatibility - The aiofile library uses native async I/O (libaio) which fails with EAGAIN (SystemError: 11, 'Resource temporarily unavailable') in containerized environments like GitHub Actions runners. - Switch to aiofiles which uses thread pool executors, providing reliable async file I/O across all environments including containers. * [autofix.ci] apply automated fixes * fix(lfx): prevent race condition in plugin discovery The discover_plugins() method had a TOCTOU (time-of-check to time-of-use) race condition. Since get() uses a keyed lock (per service name), multiple threads requesting different services could concurrently see _plugins_discovered=False and trigger duplicate plugin discovery. Wrap discover_plugins() with self._lock to ensure thread-safe access to the _plugins_discovered flag and prevent concurrent discovery execution. * [autofix.ci] apply automated fixes * feat: Introduce service registration decorator and enhance ServiceManager for pluggable service discovery - Added `register_service` decorator to allow services to self-register with the ServiceManager. - Enhanced `ServiceManager` to support multiple service discovery mechanisms, including decorator-based registration, config files, and entry points. - Implemented methods for direct service class registration and plugin discovery from various sources, improving flexibility and extensibility of service management. * feat: Enhance LocalStorageService with Service integration and async teardown - Updated LocalStorageService to inherit from both StorageService and Service for improved functionality. - Added a name attribute for service identification. - Implemented an async teardown method for future extensibility, even though no cleanup is currently needed. - Refactored the constructor to ensure proper initialization of both parent classes. * docs(pluggable-service-layer): add docstrings for service manager and implementations * feat(auth): implement abstract base class for authentication services and add auth service retrieval function * refactor(auth): move authentication logic from utils to AuthService Consolidate all authentication methods into the AuthService class to enable pluggable authentication implementations. The utils module now contains thin wrappers that delegate to the registered auth service. This allows alternative auth implementations (e.g., OIDC) to be registered via the pluggable services system while maintaining backward compatibility with existing code that imports from utils. Changes: - Move all auth logic (token creation, user validation, API key security, password hashing, encryption) to AuthService - Refactor utils.py to delegate to get_auth_service() - Update function signatures to remove settings_service parameter (now obtained from the service internally) * refactor(auth): update authentication methods and remove settings_service parameter - Changed function to retrieve current user from access token instead of JWT. - Updated AuthServiceFactory to specify SettingsService type in create method. - Removed settings_service dependency from encryption and decryption functions, simplifying the code. This refactor enhances the clarity and maintainability of the authentication logic. * test(auth): add unit tests for AuthService and pluggable authentication - Introduced comprehensive unit tests for AuthService, covering token creation, user validation, and authentication methods. - Added tests for pluggable authentication, ensuring correct delegation to registered services. - Enhanced test coverage for user authentication scenarios, including active/inactive user checks and token validation. These additions improve the reliability and maintainability of the authentication system. * fix(tests): update test cases to use AuthService and correct user retrieval method - Replaced the mock for retrieving the current user from JWT to access token in the TestSuperuserCommand. - Refactored unit tests for MCP encryption to utilize AuthService instead of a mock settings service, enhancing test reliability. - Updated patch decorators in tests to reflect the new method of obtaining the AuthService, ensuring consistency across test cases. These changes improve the accuracy and maintainability of the authentication tests. * docs(pluggable-services): add auth_service to ServiceType enum documentation * fix(auth): Add missing type hints and abstract methods to AuthServiceBase (#10710) * [autofix.ci] apply automated fixes * fix(auth): refactor api_key_security method to accept optional database session and improve error handling * feat(auth): enhance AuthServiceBase with detailed design principles and JIT provisioning methods * fix(auth): remove settings_service from encrypt/decrypt_api_key calls After the pluggable auth refactor, encrypt_api_key and decrypt_api_key no longer take a settings_service argument - they get it internally. - Update check_key import path in __main__.py (moved to crud module) - Remove settings_service argument from calls in: - api/v1/api_key.py - api/v1/store.py - services/variable/service.py - services/variable/kubernetes.py - Fix auth service to use session_scope() instead of non-existent get_db_service().with_session() * fix(auth): resolve type errors and duplicate definitions in pluggable auth branch - Add missing imports in auth/utils.py (Final, HTTPException, status, logger, SettingsService) that prevented application startup - Remove duplicate NoServiceRegisteredError class in lfx/services/manager.py - Remove duplicate teardown method in lfx/services/storage/local.py - Fix invalid settings_service parameter in encrypt_api_key calls in variable/service.py and variable/kubernetes.py - Add proper type guards for check_key calls to satisfy mypy - Add null checks for password fields in users.py endpoints * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * [autofix.ci] apply automated fixes

Reduced to 4GB (4096MB) which is sufficient for the Vite build and prevents OOM kills in memory-constrained Docker BuildKit environments. * fix: avoid redundant recursive chown on /app in backend Dockerfile The recursive chown -R on /app was re-owning the entire .venv (~2.6GB, 40k+ files) which was already correctly owned via COPY --chown=1000:0. This was causing the build to be killed on ARM64 runners. Changed to non-recursive chown on /app since only the directory itself needs ownership set. /app/data still gets recursive chown (it's empty). * fix: add Docker cleanup between image builds to prevent disk full The 40GB ARM64 runner runs out of disk when building 3 Docker images sequentially. Each image (main ~8GB layers, backend ~5GB, frontend) accumulates build cache and layers that exhaust the disk. Added cleanup steps between builds that: - Remove the tested image (no longer needed) - Prune all unused Docker data and buildx cache - Log disk usage before/after for debugging --------- Co-authored-by: Gabriel Luiz Freitas Almeida <gabriel@logspace.ai> Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Mike Pawlowski <mike.pawlowski@datastax.com> Co-authored-by: Mike Pawlowski <mpawlow@ca.ibm.com> Co-authored-by: Copilot <198982749+Copilot@users.noreply.github.com> Co-authored-by: ogabrielluiz <24829397+ogabrielluiz@users.noreply.github.com> Co-authored-by: Deon Sanchez <69873175+deon-sanchez@users.noreply.github.com> Co-authored-by: codeflash-ai[bot] <148906541+codeflash-ai[bot]@users.noreply.github.com> Co-authored-by: Lucas Oliveira <62335616+lucaseduoli@users.noreply.github.com> Co-authored-by: Viktor Avelino <64113566+viktoravelino@users.noreply.github.com> Co-authored-by: Lucas Democh <ldgoularte@gmail.com> Co-authored-by: Keval718 <kevalvirat@gmail.com> Co-authored-by: vjgit96 <vijay.katuri@ibm.com> Co-authored-by: Cristhian Zanforlin Lousa <cristhian.lousa@gmail.com> Co-authored-by: Ram Gopal Srikar Katakam <44802869+RamGopalSrikar@users.noreply.github.com> Co-authored-by: olayinkaadelakun <olayinka.adelakun@ibm.com> Co-authored-by: Olayinka Adelakun <olayinkaadelakun@Olayinkas-MacBook-Pro.local> Co-authored-by: Carlos Coelho <80289056+carlosrcoelho@users.noreply.github.com> Co-authored-by: Jordan Frazier <122494242+jordanrfrazier@users.noreply.github.com> Co-authored-by: Viktor Avelino <viktor.avelino@gmail.com> Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com> Co-authored-by: Olayinka Adelakun <olayinkaadelakun@mac.war.can.ibm.com> Co-authored-by: Mendon Kissling <59585235+mendonk@users.noreply.github.com> Co-authored-by: Hamza Rashid <74062092+HzaRashid@users.noreply.github.com> Co-authored-by: Edwin Jose <edwin.jose@datastax.com> Co-authored-by: Adam-Aghili <149833988+Adam-Aghili@users.noreply.github.com>	2026-02-24 03:55:27 +00:00
