From b530cacc15cf80436cc68ca9e245542f00f9bc24 Mon Sep 17 00:00:00 2001 From: Leo Meyerovich Date: Tue, 28 Apr 2026 00:12:36 -0700 Subject: [PATCH 1/3] fix(sso): graceful fallback when site-wide SSO JWT omits active_organization MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Restore 0.45.8 behavior at arrow_uploader.py sso_get_token: when the server's JWT response omits (or nulls) active_organization, preserve self.org_name (already populated in __init__ from register(org_name=...) or client_session.org_name) and skip _switch_org instead of raising. This unblocks customers running against site-wide-SSO servers (no per-org binding) — which legitimately omit the field — from upgrading past 0.45.8. The strict raise was introduced in 0.45.10 (PR #832 / #850 cluster). Backwards compatible: when active_organization IS present, behavior is identical to current master (use the supplied slug, call _switch_org). Replaces test_sso_get_token_missing_org_raises (which pinned the bug) with three fallback tests covering: missing field + no caller org_name, missing field + caller org_name preserved, null active_organization. Companion server-side fix: graphistry/graphistry#3002 (already merged); this client-side fix is required for older servers and for defense-in-depth on newer ones.

Adds 8 regression tests including: identity-preservation for `UnnestApply` and `PredicatePushdownPass` when no descendant is rewritten (the `rewritten_child is not child` guard is load-bearing for tier-2 fixed-point convergence), asymmetric identity preservation across `Join` when only one branch is rewritten, and a reflective `typing.get_type_hints` check that any future `LogicalPlan` subclass adding a new child slot must update `CHILD_SLOTS` (#1196, #1199). ### Fixed +- **SSO / site-wide login**: `ArrowUploader.sso_get_token` no longer raises when the server's JWT response omits (or nulls) the `active_organization` field. Site-wide-SSO servers (no per-org binding) legitimately omit this field; the strict-raise introduced in 0.45.10 broke login against such servers and forced affected enterprise customers to pin to 0.45.8 or downgrade dataset privacy. The fallback now preserves `self.org_name` as set in `__init__` (from the caller's `register(org_name=...)` kwarg or `client_session.org_name`) and skips `_switch_org`, restoring the 0.45.8 behavior. When `active_organization` IS present, behavior is identical to current master (use the supplied slug, switch org). The `tests/test_arrow_uploader.py::test_sso_get_token_missing_org_raises` regression-pinning test was replaced with three `test_sso_get_token_*` cases covering: (a) missing field + no caller `org_name` → org stays unset, no switch; (b) missing field + caller `org_name` → caller's value preserved, no switch; (c) `active_organization: null` → same fallback path. Backwards compatible with both pre-#3002 servers (which omit the field) and post-#3002 servers (which always emit it). Companion server-side fix: graphistry/graphistry#3002. - **GFQL / comparison predicates**: Mixed-type scalar comparisons in Cypher `WHERE` execution (`>`, `<`, `>=`, `<=`) now preserve null-safe filter semantics across pandas and cuDF backends instead of failing whole-series evaluation on incomparable rows. Comparable rows keep backend-native ordering; incomparable/null rows evaluate non-matching (`False`) (#1219, #1223). - **GFQL / predicate pushdown**: Fixed a silent `\b` regex bug in `_refs_for_segment` (`graphistry/compute/gfql/passes/predicate_pushdown.py`). The rf-string `rf"\\b..."` produced a literal backslash-b sequence, not a word-boundary assertion, so per-conjunct alias detection never matched and always fell back to the full original reference set — widening reference sets for every split conjunct and preventing some safe-pushable conjuncts from being recognized. Tests passed because the fallback is a superset. Also consolidated two duplicate "split WHERE body on top-level AND" implementations (one in `parser.py`, one in `predicate_pushdown.py`) into a shared helper `graphistry/compute/gfql/expr_split.py::split_top_level_and` with strictly quote/bracket/paren/backtick-aware splitting. Adds 20 direct unit tests for the shared helper and one regression test locking the `\b` fix (#1195, #1198). - **GFQL / Cypher binder**: Replaced fragile regex-based WHERE label narrowing fallback in `_apply_where_label_narrowing` with AST-derived narrowing. `generic_where_clause` now lifts AND-joined bare label predicates (`WHERE n:Admin AND n:Active`) to structured `WhereClause.predicates` using the existing quote/bracket/paren/backtick-aware `_split_top_level_and_terms` helper; string-literal false-matches (e.g. `WHERE n.name = 'n:Admin'` incorrectly narrowing alias `n`) are closed by `fullmatch` anchoring. Removes `_WHERE_LABEL_RE` and `_WHERE_NON_CONJUNCTIVE_RE` from `binder.py`. Adds 10 targeted tests covering single/double/triple AND, multi-alias, multi-label-per-alias, lowercase `and`, XOR/OR/NOT conservative non-narrowing, mixed label+property all-or-nothing, and string-literal false-positive guards (#1125, #1193). diff --git a/graphistry/arrow_uploader.py b/graphistry/arrow_uploader.py index a8d383ef25..720f98393d 100644 --- a/graphistry/arrow_uploader.py +++ b/graphistry/arrow_uploader.py @@ -428,15 +428,26 @@ def sso_get_token(self, state): self.token = token_value active_org = data.get('active_organization') - if not active_org or not active_org.get('slug'): - raise Exception( - "SSO response missing active organization; see graphistry/graphistry#2933" - ) + slug = active_org.get('slug') if isinstance(active_org, dict) else None - slug = active_org['slug'] - logger.debug("@ArrowUploader.sso_get_token, org_name: %s", slug) - self.org_name = slug - self._switch_org(slug, token_value or self.token) + if slug: + logger.debug("@ArrowUploader.sso_get_token, org_name: %s", slug) + self.org_name = slug + self._switch_org(slug, token_value or self.token) + else: + # Site-wide SSO servers legitimately omit active_organization + # when the user has no per-org binding.

Adds two new tests and strengthens two existing ones with stdlib assertLogs-based observability assertions: - test_sso_get_token_non_dict_active_organization_falls_back: pins the defensive isinstance(active_org, dict) guard. If a future refactor drops the type-check, an unexpected non-dict server payload would crash on .get('slug') instead of falling back gracefully. - test_sso_get_token_empty_slug_active_organization_falls_back: pins the `if slug:` falsy guard. Without it, an empty-string slug would overwrite self.org_name with "", silently corrupting the caller's org_name. - test_sso_get_token_missing_active_organization_no_caller_org and *_preserves_caller_org now assert via self.assertLogs(...) that the fallback INFO log fires and (where applicable) carries the caller- supplied org_name as a structured arg. Robust to message-prose changes; uses stdlib assertLogs because the test class is a unittest.TestCase subclass and pytest's caplog fixture does not compose with TestCase methods. 5 SSO-fallback tests + 1 happy-path test all green; broader SSO-adjacent suite (test_arrow_uploader / test_pygraphistry / test_client_session) 56 passed.

Layer 2 — server silent, caller supplied org_name - Preserve self.org_name; skip _switch_org. Subsequent authenticated requests will validate org membership lazily. - Logged at WARNING (was INFO) because the "caller asked, server didn't bind" outcome is operationally interesting — operators should investigate per-org SSO config. Layer 3 — server silent, caller silent - New: try JWT-derived personal-org slug (the helper _personal_org_from_jwt decodes the JWT payload without local signature verification; trust assumption documented in the helper's docstring — token was just received from the authenticated /sso/oidc/jwt/{state}/ endpoint in the same exchange; server re-validates signature on every subsequent request). - Server contract: personal_org.slug == jwt_payload.username for users auto-provisioned via SSO. Layer 4 — server silent, caller silent, no JWT username - Site-wide login completes with no org binding. INFO log. Adds 5 new integration tests (Layer-1 mismatch, Layer-1 match, Layer-3 JWT fallback, Layer-2 precedence over Layer-3) and a TestPersonalOrgFromJwt class with 11 unit cases exercising the helper's decode/parse failure modes in isolation.
