docs: migrate code blocks to native Prism and restyle API reference pages (#13299)
* docs: migrate code blocks from CodeSnippet to native Prism Replace the custom CodeSnippet component (@code-hike/lighter) with Docusaurus's native @theme/CodeBlock across all MDX files (current and versioned docs). Add bash to additionalLanguages and swizzle prism-include-languages.js to add custom token highlighting for shell commands and flags. Remove @code-hike/mdx dependency. * docs: improve inline code styling Darken inline code background, increase horizontal padding to 0.4em, fix vertical alignment, and remove border in light mode. * docs: address PR review — fix code slice regression and CSS/regex polish - Inline RecursiveCharacterTextSplitter inputs and methods as literal code blocks in concepts-components.mdx (current + 1.8.0 + 1.9.0), restoring the focused slices lost when migrating from CodeSnippet - Scope bash-plain Prism regex to unambiguous CLI subcommands only, removing generic bash builtins (run, add, get, set, start, stop, etc.) - Merge duplicate .theme-code-block CSS rules into a single declaration * fix(docs): prevent horizontal scroll on API docs pages The Redoc two-column layout (sidebar 300px + api-content 1300px) totals 1600px, expanding .main-wrapper beyond narrower viewports because it has overflow:visible. Clips at .main-wrapper using the html.plugin-redoc class that Docusaurus adds on API pages only. * fix(docs): API docs sidebar and layout fixes - Disable Redoc built-in search (disableSearch: true) - Pin sidebar top to navbar height (top: 60px) so it never hides behind navbar - Remove hardcoded #111 background from dark mode sidebar * fix(docs): render markdown correctly in API docs descriptions The _clean_descriptions function was converting newlines to <br> tags, mixing HTML with Markdown. CommonMark stops parsing Markdown headings (###) inside HTML blocks, causing them to appear as literal text in Redoc. Replace the <br> conversion with a simple strip() so descriptions remain pure Markdown and Redoc renders headings, lists, and code blocks correctly. * feat(docs): align API docs colors with Langflow brand - Set primaryColor to #F471B5 (Langflow pink) - Add HTTP method badge colors matching Langflow palette - Set schema.linesColor and requireLabelColor to brand pink - Set inline code color to pink, headers to #e3e3e3 - Set sidebar background to #18181b (matches frontend dark bg) - Set rightPanel background to #0d0d0f, codeBlock to #161618 - Refactor: move color config from CSS to theme.theme where safe - Remove dead search input CSS (search disabled via disableSearch:true) - Consolidate duplicate .menu-content rules * wip(docs): API docs styling — colors, components, light/dark themes * fix(docs): fix Response samples h3 title padding and refactor HTTP method button CSS * feat(docs): add sidebar dark background, active item styles, and right panel color adjustments * fix(docs): add sidebar borders and remove operation divider border * fix(docs): fix expanded response background and align dark/light theme colors * refactor(docs): standardize selectors, comments and remove duplicate rules in redocusaurus.css * refactor(docs): apply PR review — CSS custom properties, version pin, dom version comments, fix overflow * fix(docs): fix Redocly badge visibility covered by sidebar background * fix(docs): extend sidebar border-right to Redocly badge area * refactor(docs): replace hardcoded #ffffff label color with --redoc-text-label variable * fix(docs): lighten inline code background in API docs dark theme Redoc's default typography.code.backgroundColor (rgba(38, 50, 56, 0.05)) is nearly invisible over the dark background. Override it with rgba(255, 255, 255, 0.05) in dark theme only, excluding pre > code so code sample blocks stay unaffected. * feat(docs): align docs primary pink with API spec brand color Use #f471b5 (API spec primaryColor) as --ifm-color-primary in dark theme and #e44fa0 (slightly darkened for contrast on white) in light theme. Remove dark-theme pink overrides in sidebar.css (#ff6ad0 CTA and hsla(329, 55%, 68%) active TOC link) — they compensated for the old muted pink and are redundant now that the primary itself is bright. * feat(docs): lighten dark theme text colors for better readability Bump body text (#a8a8b0 -> #bcbcc4), headings (#cdcdd4 -> #dcdce2) and sidebar menu (#8a8a92 -> #9c9ca4) one step brighter. * chore(docs): add IBM Equal Access accessibility-checker setup Add accessibility-checker as devDependency with aceconfig.js (policy IBM_Accessibility, JSON reports in docs/a11y-results/, gitignored). Scan with: npx achecker <url> against a built docs site. * fix(docs): WCAG AA contrast and ARIA fixes across docs and API reference Validated with IBM Equal Access scans (light theme): home, quickstart and component pages at 0 violations; /api from 3382 down to 167 (all remaining are Redoc-internal DOM: schema table headers, svg/select labels). Docs site: - Light primary pink #d11074 — passes 4.5:1 on white and inline-code bg - Light Prism palette darkened per-token to pass 4.5:1 on #f9f9fd - TabItem swizzled to give tabpanels an accessible name (aria-label) - codeBlockA11y client module: scrollable code blocks get role=region + unique label; non-scrollable ones lose the needless tabindex API reference (Redocusaurus): - redocA11y client module: role=main on api-content, role=navigation on sidebar — fixes 1924 aria_content_in_landmark violations - HTTP method badges and response chips darkened to pass with white text - Light-theme overrides: accessible pink #cd1072 for links, required markers, constraint chips, schema tree lines; darker grays for utility buttons and type labels (incl. 0.7-opacity wrapper fix) - Sidebar active/hover items use regular text color, method badges keep their own colors; expandable property names match non-expandable ones * fix(docs): WCAG AA contrast fixes for dark theme Validated with IBM Equal Access scans in dark mode (temporary colorMode.defaultMode flip during scanning): home, quickstart and component pages at 0 violations; /api matches light at 167 remaining (all Redoc-internal DOM: table headers, svg/select labels). - Code block comments/line numbers #4a5060 -> #798197 (4.56:1 on #18181a) - Redoc dark sample tokens: boolean/null #e95c59, number #5392b8 - Status-code tabs: lift docusaurus-theme-redoc's #303846 !important selected-tab rule with a higher-specificity override - oneOf variant buttons: dark text in both themes (their white/pink backgrounds are theme-independent) - redocA11y client module: patch response chip colors (success green / error red) to dark-accessible variants when data-theme=dark — a single Redoc theme color cannot pass on both light and dark derived backgrounds, and status is only distinguishable by computed color * fix(docs): resolve remaining Redoc-internal accessibility violations Extend the redocA11y client module with semantic patches for Redoc DOM the theme cannot reach (validated: 0 IBM Equal Access violations on all scanned pages in both light and dark themes): - Decorative svg chevrons/arrows: aria-hidden=true (svg_graphics_labelled) - Content-type dropdowns: aria-label (input_label_exists) - Schema field tables (2-col name|description layout, no <th> anywhere): role=presentation — content reads in DOM order; role=rowheader on <td> is invalid ARIA inside a native table (table_headers_exists/related) - Semantic patches run on the next animation frame after DOM changes so Redoc's lazy-rendered operations are covered immediately; the heavier color patch stays debounced * ci(docs): gate docs accessibility with IBM Equal Access scans Add test-docs-accessibility job to docs_test.yml (rides the existing docs/** path filter from ci.yml): build + scan 4 representative pages (home, quickstart, component page, /api) in light theme, then flip colorMode.defaultMode to dark, rebuild and scan again. - scripts/a11y-ci.sh: serves the build and runs npx achecker per page with one retry to absorb Redoc lazy-render timing flakes; any real violation fails the job (failLevels: violation) - aceconfig.js: pin ruleArchive to 19May2026 so IBM rule updates don't break CI without a deliberate bump * ci(docs): fix Chrome sandbox launch on Ubuntu 24.04 runners Ubuntu 24.04 restricts unprivileged user namespaces via AppArmor, which prevents puppeteer's Chrome (used by the IBM checker) from starting its sandbox. Re-enable them with the documented sysctl workaround instead of weakening the browser with --no-sandbox. * fix(docs): align response status code with description text Redoc sets vertical-align: top and a smaller line-height on the status code <strong> inside response buttons, leaving "200" visually higher than "Successful Response". Align both to the shared text baseline. * refactor(docs): apply PR review feedback - redocA11y: match only real Redoc routes (/api, /api/workflow) — a bare startsWith("/api") also matched docs pages like /api-request and leaked one body MutationObserver per navigation - codeBlockA11y: also observe the hidden attribute — Docusaurus tabs toggle panels via hidden (no childList mutation), so scrollable blocks inside an initially hidden tab were never re-evaluated for tabindex - Extract Prism themes to src/prismThemes.js (docusaurus.config.js was past the 600-line red flag) - concepts-components.mdx (current + 1.9.0 + 1.8.0): comment pointing hardcoded snippets to recursive_character.py to mitigate drift Validated: clean build + IBM Equal Access scans 4/4 passing. * replace-openapi-file-with-1.10 * migrate-prism-changes-to-1.10-version * a11y-script-dont-block --------- Co-authored-by: Mendon Kissling <59585235+mendonk@users.noreply.github.com> |

fix(ci): resolve validate-version output in release-lfx changelog link (1.11.0) (#13612)
fix(ci): resolve validate-version output in release-lfx changelog link
The create-release job references
needs.validate-version.outputs.current_version in its generated release
notes (the Full Changelog compare link), but validate-version was not in
the job's needs array, so the expression evaluated empty and the link
rendered as compare/v...lfx-vX.Y.Z (broken base).
Add validate-version to the create-release needs. This adds no real
serialization: create-release already waits on release-lfx, which
transitively requires validate-version via run-tests, and the job's
always() if-condition is unaffected.
Flagged by actionlint: property "validate-version" is not defined in
object type {build-docker, release-lfx}.

fix(ci): create GitHub releases on the dispatched v-prefixed tag (1.11.0) (#13607)
fix(ci): create GitHub releases on the dispatched v-prefixed tag The create_release job passed the bare version (v stripped) as the release tag with no commit target, so when that tag did not exist GitHub minted a new lightweight tag at the default-branch HEAD -- the wrong commit, still carrying the previous version (main only adopts a release's version via the post-release back-merge). Every release since 1.8.2 shipped a stray bare tag (1.8.2, 1.8.3, 1.9.0-1.9.6, 1.10.0) pointing at a previous-version commit, and the GitHub release had to be manually re-pointed to the real vX.Y.Z tag after each release. - create_release now attaches the release to inputs.release_tag for stable releases; pre-releases keep their computed tag (e.g. 1.10.0rc1) but it is minted at the release commit via 'commit:'. - release-lfx.yml pins the minted lfx-v* tag to github.sha instead of the default branch. The validate-tag-format guard (#12847) only blocks at dispatch time; create_release was re-creating the very duplicates it guards against. |

fix(ci): scope nightly migration-test pre-releases to the langflow stack (1.11.0) (#13604)
fix(ci): scope nightly migration-test pre-releases to the langflow stack The previous fix (#13599) added a global --prerelease=allow, which let UNRELATED dependencies resolve to alphas: on nightly run 27274206250 the stable->nightly upgrade pulled pydantic 2.14.0a1 + pydantic-yaml 1.6.1a1, and the pydantic alpha breaks langchain-core at import time (RunnablePassthrough pydantic ValidationError), failing the nightly boot right after a successful install. Clean installs were fine - only this upgrade path resolved the alpha combo. Scope pre-release eligibility to the langflow lockstep stack instead: uv accepts a pre-release when the package's own requirement carries a pre-release marker, but not via transitive pins, and the nightly chain is langflow -> langflow-base -> lfx -> langflow-sdk with exact ==devN pins. Request each directly; langflow-sdk versions independently (0.2.0.devN), so an explicit .dev0 floor marks it eligible while lfx's exact pin selects the version. The 'latest' branch gets the same treatment via .dev0 floors on all four. Verified by dry-run against PyPI: langflow/langflow-base/lfx at 1.11.0.dev2 + langflow-sdk 0.2.0.dev2 resolve with pydantic staying at stable 2.13.4. |

fix(ci): allow pre-releases when pinning the nightly in migration validation (1.11.0) (#13600)
fix(ci): allow pre-releases when pinning the nightly in migration validation Migration Test: pip/venv (stable -> nightly) failed deterministically on nightly run 27260425158 (twice, including a rerun): hint: langflow-base was requested with a pre-release marker (e.g., langflow-base==1.11.0.dev1), but pre-releases weren't enabled (try: --prerelease=allow) This is the first nightly publishing as a canonical .devN pre-release of the langflow distribution (nightly -> stable bundle cutover). The 'latest' branch of the upgrade step already passes --prerelease=allow, but the pinned-version branches do not. uv implicitly allows the pre-release for the directly requested ==X.Y.Z.devN pin, yet langflow's metadata pins langflow-base==X.Y.Z.devN transitively, and uv rejects transitive pre-releases unless they are enabled - so the install fails after the stable uninstall, sinking the migration test. Add --prerelease=allow to both pinned-version install lines. |

fix(ci): anchor langflow-base version extraction in nightly docker build (1.11.0) (#13592)
fix(ci): anchor langflow-base version extraction in nightly docker build
The first nightly on the 1.11 workspace (tag v1.11.0.dev0, run
27253229568) failed in Build Nightly Base Package within seconds:
'Base version format is incorrect'. The extraction (uv tree, grep
langflow-base unanchored, awk field 3, first line) broke because uv
tree now prints the langflow-base workspace-root line
('langflow-base v1.11.0.dev0', two fields) before any dependency line
('langflow-base[complete] v1.11.0.dev0' under the langflow root, three
fields), so the first match yields an empty field 3 and the format
check exits 1. uv tree's stderr is discarded, which made the real
cause invisible in CI.
Anchor to the root line and take field 2 instead - the exact pattern
the langflow (main package) extraction in this same file already uses,
which is why the main-package builds passed on the same tag. Verified
both extractions print 1.11.0.dev0 against a local checkout of
v1.11.0.dev0.

fix(ci): rebalance backend test splits with measured durations + raise unit-test step timeout (#13583)
Unit Tests - Python 3.12 - Group 3 has been failing at 98-99% on the nightly: the job hits the nick-fields/retry 40-minute per-attempt timeout and pytest is SIGTERM'd mid-test, so it looks like one flaky last test when it is actually a deterministic timeout (and the internal retry plus run-level retries can never succeed). Root cause is twofold: 1. .test_durations was last regenerated ~May 2025 and covered only 2,219 of ~9,500 current unit tests, so pytest-split weighted 77% of the suite at the 0.73s average. The expensive client-fixture tests (test_webhook.py, test_login.py - each pays a full create_app + lifespan boot per test, 60-120s late in a CI run) clustered into group 3's tail, making it ~8-10 minutes slower than its siblings (33:15 on 3.13, >40min on 3.12 which is additionally slowed by astrapy disabling SSL connection reuse on Python 3.12.0-11). The weekly store_pytest_durations workflow that should refresh the file has been dying at the 6-hour GitHub job limit every week (serial full-suite run no longer fits), so the file silently froze. This regenerates the file from real per-test wall-clock measured in the passing Python 3.13 nightly jobs (run 27246228762 attempt 1, all 5 groups, parsed from the -vv xdist logs: per-worker start-to-start deltas). 9,508 tests now have measured durations; old entries are kept where no new measurement exists. Simulated least_duration split goes from one outlier group to 5 even groups (~24.6 min each) with the >50s tests spread 1-2 per group instead of 7 in one. 2. timeout_minutes 40 -> 50 gives headroom for matrix-cell variance (3.12 runs ~20% slower than 3.13) so a slightly slow cell degrades gracefully instead of burning 2x40min and failing the whole run. Follow-ups (not in this PR): fix store_pytest_durations to run with xdist or split groups so it fits the 6h limit; investigate the in-worker degradation that makes client-fixture boots cost 8-12s early in a run but 60-120s after ~30 minutes. |

feat(ci): nightly → stable bundles via canonical pre-releases + decision record [gated] (#13528)
* docs: record nightly→stable bundle cutover plan (gated on lfx 1.10.0) Add src/bundles/NIGHTLY.md documenting why langflow-nightly currently renames the bundles (lfx and lfx-nightly ship the same lfx/ import, so a stable bundle would co-install both and collide) and the deferred cutover (Approach A: canonical pre-releases; B: lfx as a bundle extra), gated on stable lfx 1.10.0 being published to PyPI. Also expand two docstrings in scripts/ci/update_lfx_version.py to state the deeper install-conflict reason, not just the resolve failure. No behavior change. * feat(ci): nightly Approach A — canonical pre-releases, drop nightly bundles [DRAFT/gated] (#13529) feat(ci): nightly Approach A — canonical pre-releases, drop nightly bundles DRAFT reference implementation of the nightly→stable-bundle cutover documented in src/bundles/NIGHTLY.md. Publishes the nightly under CANONICAL package names as .devN pre-releases instead of separate *-nightly distributions, so the stable lfx-* bundles resolve against a single canonical lfx (no dual-lfx install collision) and no nightly bundle packages are produced. - tag scripts (pypi/lfx/sdk_nightly_tag.py): count .devN against the canonical PyPI histories instead of the *-nightly projects - update scripts: stop renaming to *-nightly; set .devN versions; re-pin inter-package deps to exact canonical dev versions; delete the bundle rename/repin (update_lfx_dep_in_bundles, rename_bundles_for_nightly) - release_nightly.yml: publish canonical pre-releases; remove bundle build, dist-nightly-bundles artifact, publish-nightly-bundles job + its gate; verify canonical names; main wheel glob dist/langflow-*.whl - nightly_build.yml: drop the bundle git-add in the tag commit - NIGHTLY.md: Approach A marked implemented + activation gate + A1/A2 follow-ups Held as DRAFT: do not activate until stable lfx 1.10.0 is published AND the nightly base is the next minor (release-1.11.0). A 1.10.0.devN core sorts below 1.10.0 and would fail the bundles' >=1.10.0 floor. Stacked on #13528. (.secrets.baseline: incidental line-number shifts for the two workflows + prune of pre-existing stale Pokédex Agent.json entries.) * docs(ci): drop internal 'Approach A' label from nightly cutover comments Comment- and docstring-only change across scripts/ci/* and the two nightly workflows; no logic change. The two workflow edits stay single-line so .secrets.baseline line numbers are unaffected. src/bundles/NIGHTLY.md keeps its A/B decision-record framing intentionally. * feat(ci): make nightly consumers work with canonical pre-releases Follow-ups from the nightly cutover that are part of its blast radius (the nightly now publishes canonical `.devN` pre-releases, not `*-nightly` distributions): - version.py: derive the "Nightly" label from the `.dev` version marker, since the canonical `langflow`/`langflow-base` distribution matches first in the lookup. Keeps the startup banner and telemetry `package` field identifying nightlies. Adds a canonical-dev test; updates the base-dev assertion. - ci.yml check-nightly-status: query the canonical `langflow` project and pick the latest `.devN` release date instead of `langflow-nightly`'s `.info.version`. - db-migration-validation.yml: install the nightly as `langflow[postgresql]==<dev>` (pre-release) instead of `langflow-nightly[...]`; verify via version("langflow"). - src/lfx/README.md: nightly install is `uv pip install --pre lfx`. - NIGHTLY.md: rewrite the follow-ups section (these are addressed; Docker image, A2 meta-package, and website docs remain deferred by design). The `langflowai/langflow-nightly` Docker image name is intentionally unchanged. * fix(ci): correct nightly verify uv tree parsing + stale base-dep regex Addresses review of #13528: - release_nightly.yml LFX verify: `uv tree | grep lfx | head -n1` matches the bundle `lfx-ibm` first → 'Name lfx-ibm does not match lfx'. Root the tree with `uv tree --package lfx` so the first line is the lfx package itself. - release_nightly.yml base verify: under canonical naming `langflow-base` prints as a top-level `langflow-base v<ver>` line, so the old $2/$3 field parse read name="v0.10.0" and version="". Use `uv tree --package langflow-base` and $1/$2. - update_lf_base_dependency.py update_base_dep: regex only accepted ~=/==, so its CLI entry point couldn't match the current root dep `langflow-base[complete]>=0.10.0`. Add >= (parity with update_uv_dependency.py). The active nightly path uses update_uv_dependency.py and was unaffected. * docs(nightly): point NIGHTLY.md status at the activation gate, not draft state Per review of #13528: this file ships inside #13528 (#13529 was folded in), so the 'stacked on prep #13528' + 'held as a draft' framing is stale and misleading. Reword the status block to state the real guard is the activation gate (stable lfx 1.10.0 published AND next-minor base), not merge/draft state. Also reword the follow-ups heading 'decide before un-drafting' -> 'decide before activating'. |

fix(ci): make Biome lint non-blocking for release workflow calls (#13547)
When ci.yml is called from release.yml (inputs.release == true), a
Biome failure was blocking all downstream publish and docker jobs via
needs.ci.result == 'success'. Biome was already excluded from the
ci_success gate for PR merges, but the reusable CI workflow itself
could still fail when the lint job errored.
Add continue-on-error: ${{ inputs.release == true }} to lint-frontend
so Biome failures are informational-only during release runs, while
remaining visible (and blocking ci_success) on regular PRs.

fix(bundles): republish lfx-* at 0.1.1 with corrected pin + relax lfx floor for RC builds (#13542)
* fix(bundles): bump lfx-* bundles to 0.1.1 to republish with corrected lfx pin The published 0.1.0 artifacts on PyPI carry stale lfx pins from before the lfx 0.5.0->1.10.0 version realignment: - lfx-arxiv, lfx-duckduckgo: lfx>=0.5.0,<0.6.0 (hard-broken; the <0.6.0 cap can never resolve lfx 1.10.0) - lfx-docling, lfx-ibm: lfx>=0.5.0 (uncapped floor/cap mismatch) The source pin was already corrected to lfx>=1.10.0,<2.0.0 in #13516, but the bundles were never re-published. PyPI versions are immutable, so shipping the fix requires a version bump. Bump all four to 0.1.1 so the Release Bundles workflow cuts fresh wheels carrying the correct pin. Root pyproject keeps its >=0.1.0 floors (satisfied by 0.1.1); only the bundle dist versions and their uv.lock stamps change. * fix(release): relax bundle lfx floor for pre-release builds + idempotent bundle publish The RC pre-release run builds lfx as 1.10.0rc0, but bundles floor lfx at >=1.10.0. Under PEP 440 a pre-release sorts below the final, so 1.10.0rc0 fails >=1.10.0 and the cross-platform install test cannot resolve the bundle wheels against the RC lfx wheel. build-base/build-main/build-lfx already rewrite their inter-package deps to the pre-release version when pre_release=true; build-bundles was the only release artifact missing that step. Add it: when pre_release=true, rewrite each bundle's lfx floor to the exact pre-release version, keeping the wide <2.0.0 BUNDLE_API cap. Stable source stays at >=1.10.0 -- only RC wheels are relaxed, at build time, so no source churn or re-tag. Also make publish-bundles tolerate 'already exists' duplicate wheels on rerun, matching release_bundles.yml. |

perf(telemetry): batched off-pool writer for transactions + vertex_builds (#13126)
* perf(telemetry): batched off-pool writer for transactions + vertex_builds
Adds TelemetryWriterService that buffers transaction and vertex_build rows
in memory and drains them in batched INSERTs via a dedicated AsyncEngine
(pool_size=1 for SQLite, 2 for Postgres, max_overflow=0). Retention is
amortized in a 60s sweeper instead of running on every insert.
Producers (log_transaction, log_vertex_build) enqueue instead of opening
a DB session, so telemetry traffic no longer competes with the
request-handling pool. Falls back to the legacy direct-write path via
LANGFLOW_TELEMETRY_WRITER_ENABLED=false.
Durability: in-flight rows spill to a diskcache.Deque per PID on shutdown
and are restored on next startup; orphan PID directories left by crashed
workers are adopted.
* perf(telemetry): tighten error handling and add coverage
Review feedback from pr-review-toolkit + silent-failure-hunter:
- Retention sweep snapshots the dirty-flow sets before commit and only
clears them after it lands; a crashed sweep no longer drops the flows on
the floor, so per-flow caps cannot drift unboundedly.
- Producer fall-through is no longer silent. transaction_service and
log_vertex_build each log a one-shot WARNING when telemetry_writer_enabled
is True but the writer is not running.
- Lifespan startup failure now logs ERROR instead of WARNING — if the user
opted into the writer and it didn't come up, that's an error.
- Shutdown drain timeout no longer suppressed silently: logs a WARNING with
pending row count + a hint to raise telemetry_writer_shutdown_drain_s.
- Writer's flush loop catches asyncio.CancelledError separately and
re-prepends the in-flight batch to the buffer so teardown's disk spill
catches it.
- After 6 consecutive batch failures the writer emits a loud ERROR with
buffer depths so operators see sustained data-loss risk.
Added tests:
- test_sanitization_survives_writer_round_trip
- test_retention_failure_preserves_dirty_flows
- test_in_flight_batch_returned_on_cancel
* perf(telemetry): address copilot review
- _restore_from_disk + _adopt_orphan_outboxes now route through _enqueue so a
large disk-spilled or orphan outbox can't bypass telemetry_writer_max_queue
and OOM the process. Oldest rows are dropped and counted via the existing
dropped_transactions / dropped_vertex_builds counters.
- chmod 0o700 the outbox root + per-PID directory so sanitized-but-still-
sensitive payloads aren't exposed cross-user on multi-tenant hosts.
Suppressed on platforms where chmod is a no-op (Windows).
- Added test_adopt_orphan_outboxes_honors_max_queue.
The remaining two copilot notes (private API access to DatabaseService and
diskcache.Cache.close) were also flagged by the in-tree review; tracking
separately. The "diskcache not declared" note is a false positive — the
dependency is at src/backend/base/pyproject.toml:76.
* perf(telemetry): address coderabbit review
- Sweeper hands off dirty sets via capture-and-clear so concurrent
flushes during a retention pass aren't wiped by the post-commit
subtract; failure path restores the snapshot.

* perf(telemetry): swap diskcache outbox for stdlib sqlite (CVE-2025-69872)
Replaces the diskcache.Deque-backed spill outbox with a stdlib sqlite3
outbox (WAL mode, JSON payloads in TEXT). diskcache 5.6.3 has
CVE-2025-69872 (pickle deserialization RCE for an attacker with write
access to the cache dir), no fixed version released, and was never
declared as a dependency — import failed on Python 3.10.
The replacement is encapsulated in a small _Outbox helper that owns the
connection, schema, JSON codec, and lifecycle. The codec uses tagged
wrappers for datetime and UUID so SQLAlchemy's typed columns accept
restored payloads on the way back out.
Hardening informed by a survey of OTel collector, Fluent Bit, Vector,
Prometheus remote_write, Datadog agent, Logstash, and Filebeat:
- Per-PID outbox dirs now stamp an owner.json (hostname + Linux boot_id
or time()-monotonic() proxy). Adoption only proceeds when host+boot
match; cross-host or pre-owner-file dirs are logged and skipped so a
recycled PID after a container restart cannot pull in a stranger's
spill data.
- PRAGMA synchronous=FULL on the spill connection so the shutdown
commit hits the platter (NORMAL only fsyncs on WAL checkpoint, which
may never run if the process exits immediately after commit).
- Spill honors telemetry_writer_max_queue with drop-oldest, matching
the producer-side overflow policy so a backlogged buffer at shutdown
can neither stall teardown nor fill disk.
- append_all encodes payloads up front and only clears the deque after
the transaction commits — no more partial-drain on mid-flight SQLite
failure. drain collapses to a single DELETE FROM outbox after the
SELECT.
- Exception handlers at the spill/restore/adopt boundaries narrowed to
(sqlite3.Error, OSError) so genuinely unexpected exceptions
propagate rather than being silently logged.
Tests cover: cross-host orphan skipped, missing-owner orphan skipped,
spill cap drops oldest, and a realistic UUID+datetime payload
surviving spill → restore → SQLAlchemy INSERT.
* [autofix.ci] apply automated fixes
* fix(telemetry): name wait_for inner tasks so pyleak can filter
Integration tests using @pyleak_marker were flagging an inner asyncio
task created by the telemetry writer's `wait_for(Event.wait(), ...)`
loops. The wrapper task is auto-named (Task-N) and lands mid-await
across the test boundary, so pyleak counts it as leaked. The writer
itself shuts down cleanly via teardown; the "leak" is a pattern
mismatch with pyleak's per-test snapshot model, not a real lifecycle
bug.
Wrap Event.wait() in an explicitly named task (`telemetry-writer-tick`,
`telemetry-writer-backoff`, `telemetry-sweeper-tick`) via a small
_wait_or_shutdown helper, and extend pyleak_marker with a task_name_filter
that excludes `telemetry-*` from leak detection. CI was green on earlier
commits in this branch only because the diskcache import error
prevented the writer from starting at all — fixing the import surfaced
this latent pyleak collision.
* [autofix.ci] apply automated fixes
* [autofix.ci] apply automated fixes (attempt 2/3)
* test(telemetry): disable writer in tests so reads see writes synchronously
* perf(telemetry): age out cross-host orphan outboxes on shared volumes
A pod on a shared PV (NFS/RWX) cannot adopt rows from a dead pod on a
different host because the dead pod's hostname doesn't match. Without a
janitor those directories accumulate forever. Add an owner-file mtime
heartbeat from the sweeper plus a prune pass that deletes cross-host
outboxes whose owner file hasn't been touched within
telemetry_writer_orphan_max_age_s (default 1h). Same-host orphans still
flow through the existing adoption path.
* perf(telemetry): add byte-aware flush + drop strategy
Today the writer bounds memory by row count only, so a worker logging fat
vertex_build artifacts can hold tens of MB per row and silently dwarf the
configured max_queue. Add a size_strategy switch ('count' | 'bytes' |
'either', default 'count' for parity) with two byte thresholds:
- batch_size_bytes (256KB) caps per-flush INSERT size when bytes apply
- max_queue_bytes (200MB) drops oldest by bytes when bytes apply
Parallel sizes deques mirror the payload buffers so accounting stays
consistent across drain, spill, restore, and the cancel/retry rollback.
Single rows above the byte budget are still emitted (no row is refused);
operators get dropped_*_bytes counters alongside dropped_*.
* test(telemetry): tighten byte-strategy assertions and cover end-to-end paths
Address gaps in the byte-aware strategy tests:
- pin exact dropped counts and remaining buffer state for the drop-by-bytes
case (was 'greater than zero')
- compute exact drain count from encoded size (was a 1-4 range)
- round-trip bytes through spill+restore to verify size deque is rebuilt
- round-trip bytes through orphan adoption for the same reason
- exercise the sweeper loop end-to-end to confirm heartbeat + prune are
wired in (previously only unit-tested in isolation)
Clarify in the settings docs that the byte caps measure encoded JSON size,
not Python in-memory footprint.
* ref: updates to telemetry writer PR (#13294)
* fix(telemetry-writer): harden error handling and add missing test coverage
Critical:
- teardown() now re-raises CancelledError after awaiting the writer task so the
asyncio cancellation chain propagates correctly on lifespan task kill
- suppress(OSError) on owner file write replaced with explicit error log so
operators know when disk-spilled rows will not be recoverable on restart
High / important:
- Escalation threshold check changed from == to >= so the error log fires on
every failure past the threshold, not just the 6th
- Dead `except OSError` on time.time() - time.monotonic() changed to
`except Exception` since time functions cannot raise OSError
- Removed redundant `from uuid import UUID` inside _run_retention_pass (already
imported at module top)
- Orphan directory cleanup: replaced blanket suppress(OSError) with per-child
suppress so ENOTEMPTY on an individual rmdir doesn't abort the whole loop and
leave the parent directory leaking silently; outer failure now logs at debug
Tests (3 new):
- test_retention_sweep_caps_vertex_builds_per_vertex: inserts 8 builds for a
single vertex with max_per_vertex=3 so the per-vertex DELETE subquery
actually executes (previous test used 8 distinct vertex IDs, bypassing it)
- test_either_strategy_trips_on_bytes_first: verifies bytes can be the first
trigger under 'either' strategy (previous test only covered the count-first path)
- test_writer_retries_on_batch_failure: injects 2 flush failures then success;
confirms failed_batches increments, rows are preserved in the buffer, and
flushed_rows reflects the final successful write
* ci: add stress-tests job to nightly build pipeline
Wires the stress-tests workflow into nightly so telemetry write stress
tests run automatically. Also gates release-nightly-build and
slack-notification on stress-tests result so a stress regression blocks
the nightly release and surfaces in Slack.
* ci: run stress tests in nightly without blocking release
Stress tests are informational for now — a failure is visible in the
workflow run and Slack but does not gate the nightly release or build.
* fix(telemetry-writer): address PR review on cancelled teardown and nightly stress tests
- Add the stress-tests.yml reusable workflow (was untracked, so the
nightly stress-tests job could never resolve)
- Notify Slack on stress-tests failure (add to slack-notification gate
and FAILED_JOB detection as non-blocking)
- Run sweeper cancel, disk spill, and engine dispose in a finally so a
cancelled teardown() still persists the in-memory buffer
- Add tests for the cancelled-teardown spill path and the >= escalation
threshold; drop the misleading wait-loop in the retry test

Previously the upgrade path unwrapped {"data": ...} and passed the inner dict to the loader, which raised KeyError: 'data'. Adds happy-path tests for envelope and flat file inputs. - applier: recurse into one level of nested flow nodes (node.data.node.flow.data.nodes), matching the checker. Without this, outdated_safe nodes inside grouped components were reported but never written. Adds a regression test. - upgrade --write test: assert the envelope is preserved (name, description, endpoint_name, etc.) instead of the previous unwrapped-output expectation, so the test matches the actual fix in this PR. - Drive-by ruff cleanup: D417 docstring, SIM103, SIM108, E501, RUF059. * [autofix.ci] apply automated fixes --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> * fix(lfx/upgrade): fix loader KeyError, outer-envelope checker gap, and nested-node applier Three bugs from ogabrielluiz's PR review: 1. run/base.py loader KeyError: file-path branch unwrapped the outer envelope for the checker but passed the inner dict to aload_flow_from_json, which does flow_graph["data"] unconditionally. Re-wrap as {"data": flow_dict} before the loader call. Applied consistently to all three input paths (--flow-json, --stdin, file-path). 2. run/base.py zero-node checker for --flow-json/--stdin: those paths stored the raw parsed JSON without unwrapping, so a caller passing an exported flow {"name":..., "data":{...}} caused the checker to see zero nodes and silently pass. Now unwrap with raw.get("data", raw) matching the file-path branch. 3. applier.py nested flows never upgraded: the early `continue` on top-level nodes not in safe_ids prevented the nested-node loop from running. Restructured so the nested check fires unconditionally for every top-level node, mirroring checker.py:160-165. * fix(lfx/run): unify outer-envelope unwrap across all --upgrade-flow input paths File-path reads now call raw.get("data", raw) matching --flow-json and --stdin, so the upgrade checker always sees the inner graph. This also removes the has_envelope/re-wrap machinery that was double-wrapping outer-envelope files when passing to aload_flow_from_json. Fix two test assertions that described the old double-wrapped shape. * fix(lfx/upgrade): inject registry into upgrade_command; fix Makefile lfx pin regex - upgrade_command now accepts an optional registry parameter so tests can pass the dict directly instead of mocking load_registry_from_index - Makefile sed regex broadened from \"lfx~=.*\" to match both ~= and >= forms so make patch works after release.yml rewrites the pin - Echo label changed to LFX (synced) to clarify the variable is the shared Langflow version, not a separate LFX-specific value * fix(make/patch): fix langflow-base sed regex and validation grep The dependency in pyproject.toml is "langflow-base[complete]>=X.Y.Z", not the "langflow-base==X" form the original regex expected, so make patch silently left the pin unchanged and the validation step always failed. The sed pattern now matches any extras/operator combination and rewrites to the canonical [complete]>= form; the grep uses -F so the [complete] brackets are treated literally. * test(lfx): add patch regex tests and symmetric safe-mode envelope tests test_patch_regexes.py — 15 tests covering the Python regexes embedded in the Makefile patch target. Exercises all three substitutions (langflow-base pin, lfx pin, version field) against every realistic pin format including the >=X.Y.Z,<dev0 form that release.yml writes. Would have caught the langflow-base==.* vs [complete]>= mismatch before manual testing. test_base.py — two new TestUpgradeFlowOption tests: test_upgrade_flow_safe_envelope_inline_json_loads_successfully test_upgrade_flow_safe_envelope_stdin_loads_successfully Symmetric to the existing file-path envelope test; verifies that --flow-json and --stdin with an outer-envelope flow also pass {"data": inner} to the loader after safe upgrades, not a double-wrapped {"data": outer_envelope}. * fix(lfx/upgrade): address review: compat checker, shared gate, fail-fast registry Checker correctness: - _outputs_are_compatible: drop cosmetic display_name from the breaking check; treat widened output types as safe (flow types must be a subset of registry types), only narrowing breaks downstream edges. - _input_types_contained: stop flagging widened input_types as breaking; keep narrowing as the only breaking case; fix misleading comments. - check_flow_compatibility now recurses fully into nested grouped components (symmetric with the applier) and accepts a pre-built registry lookup. CLI/run/serve: - New lfx.upgrade.cli_gate (UpgradeFlowMode enum, UpgradeFlowError, apply_upgrade_gate) shared by run_flow and serve_command so the two --upgrade-flow paths can't diverge. - run_flow: extract _materialize_flow_dict and route gating through the shared helper. - run/serve --upgrade-flow options typed as UpgradeFlowMode (check|safe choices). - lfx upgrade: load_registry_from_index fails fast when the bundled registry is empty/missing instead of silently marking every node blocked; ASCII-only report output; new --strict flag; build the registry lookup once and reuse it. Docs/tests: - RELEASE.md: migration note for the lfx 0.5.0 -> 1.10.0 version jump. - Regression tests for the checker fixes, the shared gate, fail-fast registry, --strict, and serve --upgrade-flow parity. * [autofix.ci] apply automated fixes * [autofix.ci] apply automated fixes (attempt 2/3) * fix(lfx): consolidate flow-envelope handling and fix version-ceiling regex Extract the outer-envelope unwrap/rewrap logic (previously hand-rolled as raw.get("data", raw) with subtly different rules across serve, run, and upgrade) into a single lfx.utils.flow_envelope module with split/merge helpers. This fixes a serve bug where an enveloped flow had its inner graph written bare to the temp file, making the loader's flow_graph["data"] raise KeyError. Also fix release.yml's major.minor extraction: the greedy sed grabbed the upper bound from a range pin (>=1.10.0,<1.11.dev0), drifting the version ceiling up one minor each release cycle. Anchor to the first version instead. * fix(lfx): upgrade-flow gate reads bundled component index, not empty cache The --upgrade-flow=check|safe gate on lfx run and lfx serve rejected every flow as 'blocked'. Both call sites passed component_cache.all_types_dict to apply_upgrade_gate, but that cache is populated lazily after services start, so at gate time it is empty -- an empty registry classifies every node as blocked. The standalone lfx upgrade command was unaffected because it reads the bundled _assets/component_index.json instead. Make the gate own registry loading: apply_upgrade_gate now defaults all_types_dict to None and loads the bundled index (the same source lfx upgrade uses) via a new _load_bundled_registry helper, raising UpgradeFlowError on a missing/empty index so a broken install fails loudly instead of silently blocking every component. Both call sites pass mode= and let the gate load the registry. Existing gate tests mocked component_cache with a populated registry, which is exactly what hid the bug; repoint them at the new _load_bundled_registry seam and add regression tests that do not mock the registry, including an end-to-end run_flow check against a real clean v1.9.0 starter flow. --------- Co-authored-by: autofix-ci[bot] <114827586+autofix-ci[bot]@users.noreply.github.com> Co-authored-by: Gabriel Luiz Freitas Almeida <gabriel@logspace.ai> |

fix(ci): re-enable migration-pip-venv now that nightly bundles resolve (#13421)
The PyPI langflow-nightly is pip-installable again, so the temporary `if: false` guard added on 2026-05-28 is no longer needed. #13418 (release-1.10.0) and its forward-port #13419 (main) gave the extension bundles their own nightly track: langflow-nightly now depends on lfx-arxiv-nightly / lfx-duckduckgo-nightly / lfx-ibm-nightly, which pin lfx-nightly==0.5.0.dev* instead of an unsatisfiable stable lfx>=0.5.0,<0.6.0. Verified against the published dev57 wheels: a dry-run resolve of langflow-nightly[postgresql] succeeds (549 packages, exit 0), pulling lfx-nightly==0.5.0.dev57 via the *-nightly bundle variants. |

fix(ci): give extension bundles a nightly track so langflow-nightly resolves (#13418)
The nightly tagger renames lfx -> lfx-nightly, but the extension bundles
were published as stable lfx-<name> wheels pinning lfx>=0.5.0. So
langflow-nightly depended on the stable lfx-arxiv (etc.), which dragged in
lfx>=0.5.0 -- a version only published under the lfx-nightly name. Installing
the nightly therefore failed:
Because only lfx<=0.4.5 is available and lfx-arxiv==0.1.0 depends on
lfx>=0.5.0, ... your requirements are unsatisfiable.
Give the bundles their own nightly track, mirroring lfx/base/main:
- update_lfx_version.py now renames each src/bundles/* package to
lfx-<name>-nightly, versions it <base>.dev<N> (sharing lfx's dev number),
and repoints the root langflow deps + [tool.uv.sources] workspace entries
at the -nightly names. Each bundle's own lfx dep was already repinned to
lfx-nightly==<dev>. Only the [project] name/version change -- entry points
and the import package stay as lfx_<name>, so extension discovery is intact.
- release_nightly.yml publishes the nightly bundle wheels to PyPI and gates
publish-nightly-main on them, so langflow-nightly's exact == pins always
reference bundles published in the same run.
No build/test/Docker changes needed: the bundles are already built and
committed under the nightly tag, the cross-platform test resolves them via
--find-links, and Docker builds from the regenerated workspace lock.

fix(ci): lockstep langflow-nightly and langflow-base-nightly versions (#13413)
* fix(ci): lockstep langflow-nightly and langflow-base-nightly versions
The nightly pipeline computed each package's .devN number independently
(pypi_nightly_tag.py queried each package's own PyPI history and
incremented separately), while langflow-nightly pins an exact
langflow-base-nightly[complete]==X.Y.Z.devN dependency. Because
langflow-nightly publishes on more nights than langflow-base-nightly,
the two counters drift (live: dev54 vs dev48). Each time base lags a
publish while main succeeds, the newest langflow-nightly pins a base
dev that does not exist yet, so 'uv pip install langflow-nightly'
becomes unsatisfiable and silently falls back to a weeks-old version.
Fix: version the two packages in lockstep. pypi_nightly_tag.py now
derives a single shared dev number from max(dev across BOTH packages'
PyPI histories) + 1 (restricted to the root base_version), so main and
base always get the identical tag and main's exact pin always
references a base version built and published in the same run. The tag
is computed in a single invocation ('both' mode) so the release and
base tags cannot drift across separate calls.
Also hardens tag computation: 404 / network / malformed responses for
either package now contribute nothing instead of crashing, a
base-version bump resets the dev counter cleanly, and non-dev/final
releases never advance it.
Adds scripts/ci/test_pypi_nightly_tag.py (unit tests) and a
ci-scripts-test.yml workflow to run scripts/ci tests on PRs.
* fix(ci): fail closed on non-404 PyPI errors in nightly tag computation
_all_dev_numbers() previously returned [] for ANY failure (network error,
non-404 HTTP status, malformed 200), which is unsafe: _shared_nightly_version()
takes max(dev)+1 across both packages, so a transient lookup failure on the
higher-versioned package silently LOWERS the next tag. E.g. if the langflow-nightly
lookup fails while langflow-base-nightly reports dev48, the script would emit
v1.10.0.dev49 even though langflow-nightly already published through dev54 — the
workflow then force-recreates an old git tag and fails publishing an already-existing
PyPI version.
Fail closed: only a true 404 (package has no releases) contributes []; network
errors, 5xx/non-404 statuses, and malformed 200s now raise so the nightly job aborts
before mutating tags. Adds tests for malformed/5xx/network failures and a direct
regression test for the higher-package-lookup-failure scenario.

ci: disable pip/venv DB migration test while langflow-nightly is pip-uninstallable
The PyPI langflow-nightly is currently pip-uninstallable: its core bundle deps (lfx-arxiv, lfx-duckduckgo) pin stable lfx>=0.5.0,<0.6.0, but stable lfx tops out at 0.4.4 (the 0.5.0 line ships only as lfx-nightly, a separate package name that cannot satisfy an lfx pin). So the pip/venv migration job fails at the install step. The Docker Compose migration job is unaffected (it runs the prebuilt nightly image) and stays enabled. Re-enable once either a stable lfx 0.5.x is published to PyPI or nightly bundle variants pinning lfx-nightly are published and langflow-nightly depends on them. |

ci: sync workflow fixes from main into release-1.10.0 (fix broken nightly) (#13400)
ci: sync workflow fixes from main into release-1.10.0 Brings the latest CI/workflow fixes from main into release-1.10.0 so the nightly build is unblocked and the two branches share the same hardening. Most important fix: release_nightly.yml's "Verify Nightly Name and Version" step now uses the anchored grep '^langflow(-nightly)?[[:space:]]' instead of 'grep langflow | grep -v langflow-base | grep -v langflow-sdk'. The old filter started matching two packages once the langflow-stepflow workspace package was added, so the name became multi-line and the check failed (this is what broke the nightly build). Also carries main's fixes for cross-platform install (--prerelease=if-necessary-or-explicit), docker build workflows, db-migration-validation, and the backend test timeout bump (30 -> 40). 3-way merged from the common ancestor, so release-only changes are preserved; no release-only feature workflows are modified. |

Explicitly uninstall langflow + langflow-base before the nightly install so the namespace is fully handed over to the nightly package. --------- Co-authored-by: Eric Hare <ericrhare@gmail.com> |

* ci: stop publishing -nightly bundle variants; release bundles on demand (#13206) Bundles (lfx-arxiv, lfx-duckduckgo) change infrequently enough that a nightly cadence is overkill. Drop the rename-to-`-nightly` and bundle publish lanes from the nightly pipeline and add a dedicated workflow_dispatch-only release_bundles.yml for purposeful releases. - nightly_build.yml: drop update_bundle_versions.py invocation and the src/bundles/*/pyproject.toml git-add guard. - release_nightly.yml: remove build-nightly-bundles and publish-nightly-bundles jobs; untether test-cross-platform and publish-nightly-main from them. - release_bundles.yml (new): build all src/bundles/* wheels, run a cross-OS install smoke test, then publish to PyPI under their stable names. Tolerates already-published versions so re-runs without a version bump are no-ops. release.yml still owns bundle publishing as part of main releases. Manual follow-up (PyPI admin): delete the lfx-arxiv-nightly and lfx-duckduckgo-nightly projects from PyPI. * ci(release_bundles): build lfx wheel locally for smoke test (#13207) The release_bundles.yml smoke test installs bundle wheels into a fresh venv, which makes uv resolve their `lfx>=X.Y,<Z` pin against PyPI. When bundles are released ahead of a matching lfx (typical case — bundles ship more often than lfx bumps land on PyPI), the resolve fails: Because only lfx<=0.4.3 is available and lfx-arxiv==0.1.0 depends on lfx>=0.5.0,<0.6.0, we can conclude that lfx-arxiv==0.1.0 cannot be used. Build the lfx wheel from the current ref in the build-bundles job and install it alongside the bundle wheels in the smoke test. The lfx wheel ships as a separate `dist-lfx-smoketest` artifact and is NOT included in the publish-bundles step — only the `dist-bundles` artifact gets pushed to PyPI. * ci(nightly): re-pin bundle lfx deps to lfx-nightly during nightly build (#13208) The nightly pipeline renames the workspace `lfx` package to `lfx-nightly` in `src/lfx/pyproject.toml` and the root workspace dep, but leaves each `src/bundles/*/pyproject.toml`'s `"lfx>=X.Y,<Z"` pin unchanged. With the workspace `lfx` gone and PyPI still on lfx 0.4.3, the create-nightly-tag job's `uv lock` fails: × No solution found when resolving dependencies for split [...] ╰─▶ Because only lfx<=0.4.3 is available and lfx-arxiv depends on lfx>=0.5.0,<0.6.0, we can conclude that lfx-arxiv's requirements are unsatisfiable. `update_lfx_version.py` now also rewrites the `lfx` (or already-rewritten `lfx-nightly`) specifier in every `src/bundles/*/pyproject.toml` to `lfx-nightly==<dev version>`, mirroring how `update_lf_base_dependency` re-pins the lfx dep inside `langflow-base`. The lookahead in the regex prevents matching sibling packages like `lfx-arxiv` / `lfx-duckduckgo`. No-op when no bundle pyprojects exist (e.g. on main today), so this is safe to merge ahead of the bundle extraction landing on main. Restored the guarded `git add src/bundles/*/pyproject.toml` step so the modified bundle pyprojects ride the same commit/tag as the rest of the nightly version bumps. Cherry-pick to release-1.10.0 to unblock nightlies cut from that branch. |

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>.

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> * 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. 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. * 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 |

fix: add stream toggle back to agent (#13155)
* add stream toggle back to agent * chore: auto-bake note keys and regenerate backend locales/en.json [skip ci] * ci: stop transient Windows npm/cache flakes from failing frontend tests The nightly frontend job fails almost every day on a single Windows Playwright shard, never on actual test logic. With fail-fast:false over ~70 Windows shards each making several cache/artifact-service calls, a transient GitHub Actions cache/artifact hiccup on any one shard flips needs.setup-and-test.result to failure and reds the whole nightly (observed steps: Setup Node.js Environment, Cache Playwright Browsers, Upload Playwright Coverage Artifact). - Decouple npm caching from actions/setup-node (its internal cache step can't be made non-fatal) and replace it with a standalone actions/cache@v5 step marked continue-on-error. - Mark Cache Playwright Browsers and the artifact-upload steps continue-on-error so an infra blip can no longer fail a test shard. Only a real test/browser failure can fail a shard now.

chore: support Python 3.14 (#13085)
* feat: upgrade Docker images to Python 3.14 (experimental)
- 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
- 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
Python 3.14.5 was released on May 10, 2026. Upgrading to the latest
Python version should help reduce CVE vulnerabilities in Docker images.
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
- 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.

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> |

chore: Add DESIGN.md for Langflow's visual design system (#12830)
* docs: Add DESIGN.md specification for Langflow's visual design system Machine-readable design tokens (YAML frontmatter) paired with human-readable design rationale following the open-source DESIGN.md format from Google Labs. Intended for AI agents generating UI that must match Langflow's visual identity. Covers 129 color tokens, 15 typography scales, 50 component definitions, spacing/rounding/elevation systems, dark mode strategy, and the 14-hue data type color system used for node port encoding. * ci: Add DESIGN.md lint workflow Runs `@google/design.md lint` against DESIGN.md on pull requests that modify the file. Catches spec violations, broken token references, and WCAG AA contrast failures before merge. CLI version is pinned via env var so format spec changes require a deliberate bump. * ci: Integrate DESIGN.md lint into CI Success pipeline Replaces the standalone workflow with a job inside ci.yml so it gates the "CI Success" aggregate check. Path-filter skips the job on PRs that don't touch DESIGN.md, so cost is near-zero for normal PRs. |

* [autofix.ci] apply automated fixes
* fix: add react-i18next mock and fix sidebar nav tests for i18n migration
- Add global react-i18next mock in jest.setup.js using en.json lookups so
t(key) returns English strings instead of raw keys in test environment
- Fix sidebarSegmentedNav tests: update NAV_ITEMS expectations to use i18n
keys, and use en.json lookups for tooltip/accessibility label assertions
* feat: add LanguageSelector dropdown to globalization pipeline
Cherry-picked frontend-only changes from feat/gp-backend-i18n (6ab21559db, 3e274a84e3):
- Add LanguageSelector component with dropdown to switch UI language
- Wire LanguageSelector into AccountMenu header
- Persist language preference to localStorage in i18n.ts
- Send Accept-Language header via useCustomApiHeaders (reactive via useTranslation)
No backend files included.

* [autofix.ci] apply automated fixes
* chore: update translations from Globalization Pipeline [skip ci]
* temp: trigger gp-upload workflow test
* ci: add download-gp-bundle job to nightly build pipeline
Downloads frontend translations from Globalization Pipeline after
create-nightly-tag and before frontend tests run, ensuring tests
always validate the latest translated locale files.
- Frontend tests (Linux/Windows) now depend on download-gp-bundle
- Backend unit tests are unaffected (no frontend locale dependency)
- GP failure blocks release-nightly-build (same severity as linux tests)
* chore: remove temporary dev files from gp scripts directory
Remove BACKEND_STRINGS_STRATEGY.md (internal planning doc), test_auth.py
(GP auth debugging script), and en.json (dev-time string snapshot).
Also add venv/ to .gitignore to prevent accidental commits of the local virtualenv.

* feat(i18n): move language selector from account menu to Settings > General
- Add LanguageForm card component in GeneralPage following the existing
Card pattern (ProfilePictureForm), with immediate language switching
- English marked as "(Recommended)" via i18n key
- Remove Language row from AccountMenu dropdown
- Add settings.languageTitle/Description/Recommended keys to en.json
for upload to Globalization Pipeline
* feat(i18n): refactor language constants and improve GP pipeline
- Extract SUPPORTED_LANGUAGES into src/frontend/src/constants/languages.ts
- Update LanguageForm to import from shared constants, add aria-label
- Add settings.languageSelectAriaLabel key to en.json
- Update LanguageSelector component to use shared SUPPORTED_LANGUAGES
- Fix gp_client and download_translations scripts
- Update GP upload/download/nightly GitHub Actions workflows
- Add GP script tests
* [autofix.ci] apply automated fixes
* ci(gp): trigger upload on release branches, download via dispatch only
- Upload now triggers on push to release-* branches (instead of main)
so translators get strings once they're finalized on the release branch
- Download removes the daily cron schedule; workflow_dispatch only
since the nightly build already handles scheduled runs
* chore: update translations from Globalization Pipeline
* fix(i18n): address PR review comments — tests, nightly build decoupling, GP test workflow
- Add pytest tests for gp_client.py (HMAC auth, HTTP errors, timeout)
- Add pytest tests for upload_strings.py and download_translations.py
- Add conftest.py to set sys.path so GP scripts can be imported from repo root
- Add scripts/gp/__init__.py to make gp a proper package for test imports
- Add gp-test.yml workflow to run GP script tests on PRs touching scripts/gp/**
- Decouple download-gp-bundle from nightly build chain:
- Add continue-on-error: true so GP failure never blocks the build
- Remove download-gp-bundle from needs/if of frontend-tests-linux,
frontend-tests-windows, and release-nightly-build
- Add warning annotation step that fires on GP download failure
* feat(i18n): lazy-load non-English locale files via Vite dynamic imports
- Remove 6 static locale imports from i18n.ts; only en.json is bundled
- Export loadLanguage() which dynamically imports a locale chunk on demand
and caches it via i18n.hasResourceBundle (no-op on repeat calls)
- Update index.tsx to await loadLanguage(detectedLang) before rendering,
preventing an English flash for non-English users
- Make handleChange async in LanguageForm and LanguageSelector to await
loadLanguage before calling i18n.changeLanguage
- Add i18n.test.ts covering loadLanguage: en no-op, new language load,
cache hit, and multiple independent languages
- Update LanguageForm.test.tsx to mock @/i18n and assert loadLanguage
is called before changeLanguage on language switch
* [autofix.ci] apply automated fixes
* [autofix.ci] apply automated fixes (attempt 2/3)
* fix: add ruff ignores for scripts/gp/tests
- Add per-file ignores for scripts/gp/tests/* to fix CI failures
- Ignore S101 (assert usage), TRY003, EM101 for test files
- Follows existing pattern for other test directories
* [autofix.ci] apply automated fixes
* fix(ci): run GP translation download before nightly tag creation
Previously download-gp-bundle ran after create-nightly-tag, so fresh
translations were committed to the branch after the tag was already
created. The nightly Docker image builds from the tag, meaning it never
included the day's translations.
Fix: move download-gp-bundle to run before create-nightly-tag so the
tag is created on a commit that already includes the latest translations.
* fix(ui): replace native select with Radix UI Select in LanguageForm
Swaps the native <select> element for the existing Radix UI Select
component to get consistent padding on both sides of the chevron,
removing reliance on browser-rendered chevron positioning.
* feat: backend i18n — serve translated component metadata via Accept-Language
- Add locale middleware (set_locale) in main.py to parse Accept-Language header
- Add translate_component_dict() in utils/i18n.py to substitute display_names
- Add backend locale files (en/fr/es/de/pt/ja/zh-Hans) with 4,748 keys
- Add GP scripts: extract_backend_strings.py, upload_backend_strings.py, download_backend_translations.py
- Add CI workflows: gp-backend-check.yml (PR validation + auto-commit), gp-backend-upload.yml (release branch upload)
- /api/v1/all returns translated component metadata for non-English locales
* chore: auto-regenerate backend locales/en.json [skip ci]
* chore: auto-regenerate backend locales/en.json [skip ci]
* refactor: simplify GP backend workflows to remove duplication
- gp-backend-check: drop redundant --check job, keep only auto-commit
- gp-backend-upload: remove extraction/commit steps, trigger on en.json
path change, and add latest-release-branch guard (mirrors gp-upload.yml)
* feat: add nightly backend translation download job to gp-download workflow
Mirrors the existing frontend download job — resolves latest release branch,
runs download_backend_translations.py, and opens an auto-merge PR.
* [autofix.ci] apply automated fixes
* fix: skip backend translation download on nightly schedule
Backend download only runs on workflow_dispatch — the nightly cron is
for the frontend build pipeline only.
* fix: remove backend GP download from nightly build workflow
Backend translations are now downloaded via workflow_dispatch in
gp-download.yml, not as part of the nightly build pipeline.
* fix: remove frontend GP download from nightly build workflow
Frontend translations are now downloaded via nightly cron in
gp-download.yml, not as part of the nightly build pipeline.
* fix: remove en.json from check workflow trigger paths
The extraction script only reads from lfx.components — en.json is never
edited directly, so triggering on it was redundant and would silently
overwrite any intentional manual edits.
* fix: mock lfx.components in sys.modules for collect_strings test
The test was failing because collect_strings() imports lfx.components
before reaching the pkgutil/importlib mocks. Injecting fake modules into
sys.modules lets the import succeed so the mocks can take over.
* fix: resolve ruff violations in GP scripts and main.py
- Use .values() instead of .items() when attr_name is unused (B007/PERF102)
- Split long print f-string to stay under 120 chars (E501)
- Add blank line in docstring between summary and description (D205)
- Use ternary operator for locale assignment in main.py (SIM108)
* feat(i18n): sync canvas node translations on language change
Add syncNodeTranslations() to flowStore that patches translatable
metadata (display_name, description, template field display_names,
output display_names) on all canvas nodes when the types catalog is
refreshed with a new language. Field values are never touched. Nodes
whose type is absent from the catalog (custom-code, group nodes) are
skipped.
Called from two places to handle the race between flow loading and
types fetching:
- use-get-types.ts after setTypes(data) — covers the case where nodes
are already on canvas when translations arrive
- resetFlow — covers the case where translations are already loaded
when the flow mounts
* feat(i18n): translate Templates modal and starter flow metadata
## Backend
- Extend extraction script (`scripts/gp/extract_backend_strings.py`) to
auto-discover all `initial_setup/starter_projects/*.json` files and emit
`starter_flows.{safe_key}.name` / `starter_flows.{safe_key}.description`
keys — no manual work needed when new starter flows are added.
- Add `translate_starter_flows()` to `utils/i18n.py`, mirroring the
existing `translate_component_dict()` pattern. Derives a stable
`name_key` (slug) from the English name and attaches it to each
`FlowRead` so the frontend can match flows by identity regardless of
locale.
- Update `FlowRead` model to expose `name_key: str | None`.
- Refactor `read_basic_examples()` endpoint (`api/v1/flows.py`):
- Accept `Request` parameter to read `request.state.locale` (set by
existing `set_locale` middleware).
- Cache the raw `flow_reads` list instead of the compressed response so
the same DB result can be translated per-request (cheap: ~33 dict
lookups, no additional DB hit).
- Call `translate_starter_flows()` on every request so `name_key` is
always populated.
- Update all 7 backend locale files (en, fr, de, es, ja, pt, zh-Hans)
with new `starter_flows.*` keys from GP.
## Frontend
- Templates modal (`modals/templatesModal/`):
- Translate sidebar title, category group labels ("Use Cases",
"Methodology"), and all nav item labels.
- Translate "Get started" header and description.
- Translate card category badges (PROMPTING, RAG, AGENTS).
- Translate search placeholder and "No templates found" empty state.
- Translate "Start from scratch" footer and "Blank Flow" button.
- Use `flow.name_key` (stable slug) for example lookup in
`GetStartedComponent` so matching is locale-independent.
- Refetch examples on language change: add `i18n.language` to the
`useGetBasicExamplesQuery` cache key so React Query re-fetches
translated flow data whenever the UI language switches.
- Add `name_key?: string | null` to `FlowType`.
- Empty state pages (`emptyPage`, `emptyFolder`): translate "Empty
project", "Start building", description, and "New Flow" button.
- Update all 7 frontend locale files with new `templatesModal.*` and
`emptyPage.*` keys from GP.
* [autofix.ci] apply automated fixes
* [autofix.ci] apply automated fixes (attempt 2/3)
* feat(i18n): translate MCP Server tab and fix sidebar category truncation
- Translate all strings in McpServerTab, McpFlowsSection, McpAuthSection:
title, description, guide link, Flows/Tools label + tooltip, Edit Tools
button, Auth label, None (public), Edit/Add Auth, Auto install tab,
Loading state, config error messages
- Use stable id/label split for Auto install / JSON tabs so mode
comparison is locale-independent
- Add truncate to sidebar category label span to prevent long translated
names (e.g. French "Mannequins et agents") from wrapping to two lines
- Update all 7 frontend locale files with new mcp.* keys from GP
* feat(i18n): translate Knowledge, Files pages and fix sidebar overflow
- Translate Knowledge page (empty state, search, loading, alerts, chunks page)
- Translate My Files page (title, empty state, table columns, upload/delete)
- Fix sidebar category label overflow with min-w-0 truncate on flex spans
- Fix "Discover more components" button text truncation
- Fix empty page CTA button max-width for longer translations
- Remove duplicate language selector from account menu (browser auto-detection already in i18n.ts)
- Upload 471 strings to GP and download translations for fr/ja/es/de/pt/zh-Hans

* feat(i18n): translate StepperModal footer buttons (Next Step, Back, Need Help?)
* feat(i18n): translate model input dropdown (No Models Enabled, Refresh List, Manage Model Providers)
* feat(i18n): translate Model Providers modal (config form, model selection, disconnect warning, multiselect placeholder)
* feat(i18n): translate starter template note/README nodes at serve-time
- Extend extract_backend_strings.py to extract noteNode descriptions as
template_notes.{flow_key}.{index} keys (64 notes across 32 templates)
- Add translate_flow_notes() to i18n.py to substitute translated markdown
per-request without mutating the cached template data
- Wire translate_flow_notes() into the /starter-projects/ endpoint using
the same request.state.locale pattern as the flows endpoint
- Update all 6 backend locale files via GP pipeline (4858 keys total)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat(i18n): translate canvas note nodes on language change via dedicated endpoint
- Add stamp_note_keys() to i18n.py: stamps i18n_key onto noteNodes of
starter templates when a user copy is created, enabling stable lookup
- Call stamp_note_keys() in _new_flow() (flows_helpers.py) so keys are
persisted to DB at copy-creation time
- Add GET /flows/{flow_id}/note_translations endpoint returning
{ node_id: translated_text } for the request locale; falls back to
positional recompute for flows without stamped keys
- Add useGetNoteTranslationsQuery (React Query) keyed on [flowId, language]
so it auto-refetches on language change without explicit invalidation
- Apply translations in NoteNode via useEffect on query data
- Rewrite syncNoteTranslations to accept Record<string, string> (node_id map)
- Remove old syncNoteTranslations(FlowType[]) approach and all debug
console.warn/console.error [i18n-debug] statements
- Suppress i18next Locize promotional console.info by temporarily replacing
console.info around the synchronous init() call
- Add i18n_key?: string to noteClassType frontend type
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat(i18n): fix Playground/Share button overlap and translate Share button
- Remove fixed w-[7.2rem] from SimpleSidebarTrigger and DisabledButton so
the Playground button grows to fit translated text in any language
- Add misc.share i18n key and replace hardcoded "Share" string in
deploy-dropdown with t("misc.share")
- Download GP translations for de/pt/zh-Hans
* feat(i18n): translate input placeholder and info fields for backend components
Extend the backend i18n pipeline to cover placeholder and info (tooltip)
text in addition to display_name and description:
- extract_backend_strings.py: extract placeholder from input fields
- i18n.py (translate_component_dict): translate placeholder and info at
request time alongside display_name
- Regenerate en.json (6700 keys, +179 placeholders, +info keys)
- Download translated locale files for de, es, fr, ja, pt, zh-Hans
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* feat(i18n): translate Share dropdown items (API access, Export, MCP Server, Embed, Shareable Playground)
* fix(i18n): stamp i18n_key in translate_flow_notes and remove dead stamp_note_keys
- Stamp i18n_key onto noteNodes inside translate_flow_notes() using the
original English name_key so the key travels with the node when a user
copies a template — fixes translation failure for duplicate copies like
"Simple Agent (2)" where the frontend sends the translated name
- Remove stamp_note_keys() and its call in _new_flow(): now a no-op since
i18n_key is always stamped by translate_flow_notes at /basic_examples/
- Remove positional fallback from get_note_translations: only use stamped
i18n_key; drop unused _safe_flow_key import and note_index counter
- Fix read_basic_examples to pass name_key (original English) instead of
the already-translated flow.name to translate_flow_notes
* refactor(i18n): bake i18n_key into template noteNodes, remove runtime stamping
Replaces fragile positional indexing with keys baked directly into the source
JSON files, so keys are stable regardless of node order changes.
- scripts/gp/bake_note_keys.py: new script that stamps template_notes.{flow}.{n}
onto each noteNode missing an i18n_key; idempotent and --dry-run safe
- scripts/gp/extract_backend_strings.py: Tier 4 reads i18n_key from node data
instead of positional index; warns if any noteNode is missing a key
- utils/i18n.py: translate_flow_notes() simplified — reads baked key, translates,
no more flow_name param or index counter or stamping logic
- api/v1/flows.py, starter_projects.py: drop flow_name arg from call sites
- test_i18n_note_translation.py: tests updated for key-read behavior
- starter_projects/*.json: 64 noteNodes across 32 templates stamped with i18n_key
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* ci(i18n): auto-bake note keys on template JSON changes in CI
Extends gp-backend-check.yml to trigger on starter_projects/** changes
and runs bake_note_keys.py before extract_backend_strings.py so any new
noteNodes get i18n_key stamped automatically on PR branches.
* refactor(i18n): replace index-based note keys with content-hash keys
bake_note_keys.py now derives i18n_key from sha256[:8] of the
noteNode description instead of a positional counter. Keys are
stable on reorder, auto-rotate when content changes, and never
silently reuse an old index after a note is deleted.
All 64 note keys across 32 starter templates restamped to the
new template_notes.{flow_key}.{hash8} format. Script is idempotent —
running twice on unchanged content produces no changes.
* fix(i18n): thread-safe translation loading and correct falsy key check
- _load_translations(): add double-checked locking with threading.Lock to
prevent race condition under concurrent requests at cold start
- translate(): use `is not None` instead of truthiness check so empty-string
translations are not silently dropped in favour of the fallback chain
* feat(i18n): translate Settings page UI strings across multiple sections
- Profile picture chooser: translate People/Space category labels
- MCP Servers page: translate title, description, button, status labels, dropdown items, and all Add MCP Server modal strings
- API Keys page: translate column headers (Name, Key, Created, Last Used, Total Uses) and Create API Key dialog (title, description, labels, buttons, generated key message)
- Shortcuts page: translate all 27 shortcut display names via valueFormatter
- Messages page: translate title and description
- Base modal: translate shared Cancel button
* fix(i18n): replace fixed card heights with min-h to prevent layout issues with longer translations
Cards with h-[84px] would overflow/misalign when translated text wrapped to
multiple lines. Using min-h-[84px] keeps the minimum size while allowing
cards to grow naturally for longer translations.
* feat(i18n): translate SaveChangesModal (unsaved changes popup)
Translates all strings in the unsaved-changes dialog shown when
navigating away from a flow with pending changes:
- title, saving spinner, last saved, exit/save buttons
- unsaved changes warning and auto-saving help link
* chore(i18n): download updated frontend and backend translations from GP
Frontend: 704 strings across fr, ja, es, de, pt, zh-Hans
Backend: updated note keys (hash-based) across fr, ja, es, de, pt, zh-Hans
* feat(i18n): translate ToolsModal (URL/tools selection popup)
Translates all strings in the tools modal including:
- search placeholder, column headers (Name, Description, Slug/Tool)
- sidebar labels, input placeholders, hint text

* refactor(i18n): content-hash component keys and normalize frontend lookup
Backend locale keys for components now use a hybrid format:
components.{norm_name}.{field_path}.{sha256[:8]}
e.g. components.prompttemplate.display_name.8cd80ebe
The 8-char hash suffix is derived from the English source value, so any
change to a component string produces a new key, forcing GP to issue a
fresh translation. The human-readable prefix keeps keys debuggable.
Component names are normalized (spaces removed, lowercased) in both the
key prefix and the runtime hash computation, so renames like
"PromptTemplate" → "Prompt Template" don't break existing translations.
Frontend syncNodeTranslations() now builds a normalized lookup map so
that nodes stored with old-style type names (e.g. "PromptTemplate") are
correctly resolved against the live registry key ("Prompt Template"),
fixing untranslated Prompt Template nodes in starter template flows.
Also adds chunked uploading to upload_backend_strings.py to avoid
read timeouts when pushing large payloads to GP.
* feat(i18n): fix legacy component alias translation and translate file manager UI
Frontend:
- syncNodeTranslations() now falls back to templates store to resolve legacy
node.data.type aliases (e.g. "Prompt" → Prompt Template, "parser" →
ParserComponent), fixing untranslated nodes in starter templates like
Vector Store RAG
- Translate "Flow saved successfully!" toast in FlowPage
- Translate file manager modal: "Select files" button, error/success toasts,
drag-and-drop zone labels, folder selection strings (13 new keys)
Backend:
- check_backend_status.py: new script to check GP translation progress
- upload_backend_strings.py: single PUT with 5min timeout, bundle name logged
- download_backend_translations.py: bundle name logged on start
- All locale files updated with latest GP translations (langflow-ui-backend-v2)

- Add useTranslation to ModelProvidersPage for page title and description
- Add canvas.* and modelProviders.page* keys to en.json
- Sync all locale files (fr, ja, es, de, pt, zh-Hans) via GP pipeline
* feat(i18n): translate upload folder button and model trigger strings
- UploadFolderButton: replace hardcoded "Upload a flow" tooltip with t("folder.uploadFlow")
- ModelTrigger: replace hardcoded "No models enabled" and "Select a model" with t() calls
* feat(i18n): cache /basic_examples/ translations per locale
Add _starter_flows_translated_cache keyed by locale so translate_starter_flows
and translate_flow_notes run at most once per locale per 5 minutes instead of
on every request.
* feat(i18n): translate NoteNode empty placeholder text
* feat(i18n): translate slider labels, model trigger, dropdown loading, and loading component
- Translate Precise/Balanced/Creative/Wild slider labels and min/max labels

- Add syncNodeTranslations() call after model refresh to re-apply translations
- Add 8 new keys to en.json and download translated locale files
* feat(i18n): translate model provider toast notifications
Replace hardcoded English strings in useProviderConfiguration with t()
calls: configuration saved, activated, disconnected success toasts, and
all error titles/messages for save, activate, disconnect, and model
toggle operations.
* fix(i18n): address PR review — DRY key functions, locale allow-list, dead code, silent failures
- Extract safe_flow_key/normalize_component_key/content_hash/component_field_key into
langflow/utils/i18n_keys.py so runtime translator and extract script share one
source of truth (C1)
- Validate Accept-Language against supported locales in set_locale middleware;
unknown values fall back to "en" to prevent cache pollution (C2)
- Delete dead `remaining = ...` block in check_backend_status.py that made a
redundant network call and never used the result (I2)
- Log logger.warning instead of silently swallowing OSError/JSONDecodeError in
_load_translations (I3)
- Rename test_strips_dedup_suffix → test_parentheses_in_name_become_underscores
with corrected comment (I5)
- Remove redundant `import copy as _copy` inside translate_flow_notes (R2)
- Move translate_flow_notes/translate_starter_flows import to flows.py module top (R1)
- Add # Why: comments on max_size=16, uncompressed cache, and verify=False (R5/I8/M3)
- Wrap loadLanguage dynamic import in try/catch so unknown locales don't crash
React with an unhandled rejection; add i18n.test.ts to cover the fallback
* refactor(gp): consolidate upload/download scripts with --target flag
Replaces four separate scripts (upload_strings, upload_backend_strings,
download_translations, download_backend_translations) with two unified
entry points: upload.py and download.py, each taking --target frontend|backend.
Updates gp-upload.yml to a single workflow with two jobs, updates
gp-download.yml run lines, and removes the now-redundant
gp-backend-upload.yml workflow.
* [autofix.ci] apply automated fixes
* chore(starter-projects): sync starter project snapshots with release-1.10.0
Updates dependency versions (langchain_core 1.2.29 → 1.2.27) and minor
JSON formatting differences across 21 starter project files following
merge from release-1.10.0.
* chore: auto-bake note keys and regenerate backend locales/en.json [skip ci]
* feat(i18n): restore LanguageForm component in Settings > General page
* [autofix.ci] apply automated fixes
* [autofix.ci] apply automated fixes (attempt 2/3)
* fix(projects): always use English for new project names
Translated project names (e.g. Japanese '新規プロジェクト') caused MCP
server name collisions because sanitize_mcp_name() strips non-ASCII
chars and all names fell back to 'lf-unnamed'. Hardcode 'New Project'
and 'Starter Project' instead of passing them through t() so the
names sent to the backend are always ASCII.
* chore(i18n): download missing Vector Store RAG note translations
README and Load Data Flow note keys were missing from all non-English
locales. Uploaded to GP and downloaded translations for fr, ja, es,
de, pt, zh-Hans.
* [autofix.ci] apply automated fixes
* fix(canvas): fix zoom dropdown shortcut layout on Windows
The shortcut container had a fixed w-[25px] which fits the single-char
Mac modifier key (⌘) but clips the 4-char Windows modifier key (Ctrl).
Remove the fixed width and use gap-0.5 so the container sizes to its
content on all platforms.
* fix(i18n): sync tooltip info and placeholder fields for existing canvas nodes
syncNodeTranslations() was only updating display_name from fresh component
definitions, leaving baked-in English info (tooltip) and placeholder strings
on nodes loaded from saved flows and starter templates. Extend the merge to
also overlay info and placeholder for template fields, and info for output
fields. Also adds info?: string to OutputFieldType to match what the backend
already sends.
* fix(i18n): persist language selection across page refreshes
loadLanguage() was only adding the resource bundle but never calling
i18n.changeLanguage(), so the active language stayed "en" on every page
load even when a preference was saved in localStorage. Move the
changeLanguage() call into loadLanguage() so both startup (index.tsx)
and runtime language switches activate the language after loading the bundle.
* fix(sidebar): add tooltip to truncated category header labels
Category headers use truncate but had no tooltip, making long translated
names (e.g. French) unreadable. Wrap the label span with ShadTooltip
matching the pattern used by sidebar draggable items.
* fix(sidebar): add tooltip to truncated discover more components button
* fix(sidebar): add tooltips to footer buttons (new custom component, MCP)
* fix(login): center-align title to handle wrapped translations gracefully
* fix(signup): center-align title to handle wrapped translations gracefully
* fix: remove tooltips from form field labels and add tooltip to sign-in button for consistency
* [autofix.ci] apply automated fixes
* chore: auto-bake note keys and regenerate backend locales/en.json [skip ci]
* [autofix.ci] apply automated fixes
* fix: resolve ruff violations in gp scripts and i18n util
- FBT001: make dry_run keyword-only in bake_note_keys._bake_file
- S112: add S112 to noqa comments in extract_backend_strings.py
- PLW2901: rename shadowed loop variable in i18n.translate_note_nodes
* [autofix.ci] apply automated fixes
* fix: lazy-import langflow in extract_backend_strings to fix GP test collection
The top-level `from langflow.utils.i18n_keys import ...` caused an
ImportError in CI where the GP test job runs without langflow installed.
Move the imports inside collect_strings() so the module is importable
without langflow — all tests mock collect_strings anyway.
* fix(tests): mock langflow.utils.i18n_keys in test_collect_strings_skips_deactivated_modules
The test calls collect_strings() directly, which now lazy-imports
langflow.utils.i18n_keys. Patch a minimal fake module into sys.modules
so the test runs without langflow installed. Also fix the key assertion
to match the lowercased output of normalize_component_key.
* fix(frontend): restore missing modal height constant imports in KnowledgeBaseUploadModal
