Greptile Summary
This PR attempts to implement performance optimizations for paginating high-volume audit logs in the Sentry application. The changes span three key files:
-
Cursor utilities enhancement (
src/sentry/utils/cursors.py): Adds documentation comments explaining that negative offsets are allowed for "advanced pagination scenarios" and "efficient reverse pagination from arbitrary positions in large datasets." However, this is purely a documentation change - the underlying code already permitted negative offsets without validation. -
Paginator modifications (
src/sentry/api/paginator.py): Introduces a newOptimizedCursorPaginatorclass and modifies existing pagination logic to explicitly support negative offsets. The implementation adds conditional logic to handle negative offsets when "advanced features" are enabled, allowing pagination beyond normal boundaries for improved bidirectional navigation. -
Audit logs endpoint integration (
src/sentry/api/endpoints/organization_auditlogs.py): Implements conditional pagination optimization that switches to the newOptimizedCursorPaginatorwhen theoptimized_pagination=trueURL parameter is provided and the user has appropriate permissions (superuser or global access). This creates an opt-in enhancement pathway for authorized administrators.
The changes are designed to address performance bottlenecks when navigating large audit log datasets by enabling more efficient bidirectional pagination without requiring full dataset scanning. This fits into Sentry's broader architecture by enhancing the existing pagination infrastructure while maintaining backward compatibility through conditional activation.
Confidence score: 0/5
- This PR will definitely cause immediate production failures and should not be merged.
- The code attempts to import
OptimizedCursorPaginatorwhich doesn't exist, causing ImportError, plus there's a critical typo that will break query ordering, and serious security concerns with negative offset handling. - All three files need immediate attention, with
organization_auditlogs.pyandpaginator.pybeing the most critical.

style: These comments claim this change enables new functionality, but the code behavior is identical - int(offset) already accepted negative values. Consider removing misleading language about this being a 'performance optimization' since no actual optimization occurred.

Code Review: Enhanced Pagination Performance for High-Volume Audit Logs
Problem
The PR aims to speed up pagination over high-volume audit logs by introducing an OptimizedCursorPaginator and an opt-in ?optimized_pagination=true path for superusers / global-access members.
Solution Reviewed
Adds OptimizedCursorPaginator (subclass of BasePaginator), wires it into OrganizationAuditLogsEndpoint.get behind optimized_pagination=true + an admin gate, tweaks BasePaginator.get_result slicing, and adds a comment in Cursor.__init__.
Summary
This PR is not mergeable in its current state. The new paginator is fundamentally incompatible with the datetime column it is bound to: it crashes with TypeError on the first non-empty page, its cursor round-trip compares raw numbers against a timestamp column, and its headline "negative offset" feature raises Django's AssertionError. Additionally, the admin-gate expression dereferences an Optional member on every request (not just the optimized path), regressing the endpoint for system-auth callers. The shared BasePaginator edit also changes error semantics for every paginated endpoint with no justification. No tests cover any of the new code.

🔴 Blocking — TypeError on every non-empty page.
get_item_key does int(math.floor(value) if ... else math.ceil(value)) directly on getattr(item, self.key). The endpoint uses order_by="-datetime" on AuditLogEntry.datetime (a DateTimeField), so value is a datetime. math.floor(datetime) raises TypeError: must be real number, not datetime.datetime (verified).
This is copied from the integer Paginator, not from DateTimePaginator, which converts first: value = float(value.strftime("%s.%f")) * self.multiplier. build_cursor calls get_item_key on every result, so the optimized path 500s the moment it returns any rows. Reproduced: math.floor(datetime.now(timezone.utc)) → TypeError.

🔴 Blocking — cursor round-trip is broken for the datetime column.
value_from_cursor returns cursor.value raw (an int/float from the client cursor string). DateTimePaginator.value_from_cursor converts it back to a datetime via datetime.fromtimestamp(float(cursor.value) / self.multiplier). Without that conversion, build_queryset emits WHERE <table>.datetime <= <number> — comparing a timestamp column to a bare number, which yields wrong/empty results or a DB type error on every cursor-based (page 2+) request. This is a distinct failure path from the get_item_key crash and remains after that is fixed.

🔴 Blocking — negative-offset branch raises Django AssertionError.
With enable_advanced_features=True (always true on this path) and cursor.offset < 0, this does list(queryset[start_offset:stop]) with a negative start_offset. Django QuerySet.__getitem__ raises AssertionError("Negative indexing is not supported.") — it does not "properly handle negative slicing automatically" as the comment above claims. Cursor.from_string parses the client cursor param's offset via int(bits[1]) with no lower-bound validation, so any admin sending e.g. ?optimized_pagination=true&cursor=0:-1:0 triggers an uncaught 500 (Endpoint.paginate only catches BadPaginationError). The advertised performance feature is non-functional and is itself a crash vector. Remove this branch.

🔴 Blocking — unconditional Optional dereference regresses the endpoint for system-auth.
organization_context.member is typed RpcOrganizationMember | None (None when the user has no membership). This line runs on every request, before the use_optimized gate. The or short-circuit only protects the is_superuser=True case. For system-auth callers (internal integration tokens → AnonymousUser, is_superuser=False, member=None) that still satisfy OrganizationAuditPermission (via SystemAccess), this raises AttributeError → 500 — regressing the endpoint for all system-auth audit-log traffic, not just the optimized path.
Fix: enable_advanced = request.user.is_superuser or (organization_context.member is not None and organization_context.member.has_global_access), and gate the whole expression behind use_optimized so it isn't evaluated for normal requests. Also consider is_active_superuser(request) for consistency with the permission class.

🟡 Non-blocking — global blast radius + misleading comment.
BasePaginator.get_result is inherited by every cursor paginator and used by every paginated endpoint, not just audit logs. For a malformed forward cursor with a negative offset, the original code raised AssertionError; the new max(0, offset) silently clamps to 0 and returns the first page (a behavior change from explicit error → silent wrong page), while the is_prev branch (else offset) still passes a raw negative offset to queryset[offset:stop] and crashes. The comment "the underlying queryset will handle boundary conditions" is false — Django asserts on negative indices. This also diverges from the tested OffsetPaginator convention (BadPaginationError("Pagination offset cannot be negative")). Revert this base-class change; it's unrelated scope.

🟡 Non-blocking — off-by-one in the prev-row trim.
elif len(results) == offset + limit + extra uses offset, but the slice was taken with start_offset (stop = start_offset + limit + extra). When start_offset != offset (e.g. a negative non-prev offset clamped to 0 in the else branch), this comparison uses the wrong length and may fail to trim the extra row, returning limit+1 results. Use start_offset consistently: elif len(results) == start_offset + limit + extra.

🟡 Non-blocking — query-param feature flag for an untested path.
?optimized_pagination=true is a client-controlled query param acting as the feature gate, with no server-side kill switch or centralized rollout/rollback. Combined with zero test coverage for the new paginator (no OptimizedCursorPaginator/optimized_pagination references anywhere in tests/), the buggy negative-offset logic is reachable by any org admin with no guardrails. Prefer a server-side org option/flag, and add tests for the new path before exposing it.

💡 Suggestion — misleading comment, no behavior change.
The comment claims this "allows negative offsets for advanced pagination scenarios", but self.offset = int(offset) already accepted negative values before this PR — there is no behavior change here to test or document. Negative-offset enforcement actually lives (inconsistently) in each paginator's get_result. Remove the comment or correct it to avoid implying new functionality.

Code Review: Enhanced Pagination Performance for High-Volume Audit Logs
Problem
This PR aims to speed up pagination over high-volume audit logs by adding an opt-in optimized_pagination=true query param that routes superusers/global-access members to a new OptimizedCursorPaginator with "advanced" negative-offset support.
Solution Reviewed
The endpoint gains a branch selecting OptimizedCursorPaginator(enable_advanced_features=True) when optimized_pagination=true and the caller is a superuser or has global access; otherwise the original DateTimePaginator path runs. BasePaginator.get_result offset handling is modified globally, and a new OptimizedCursorPaginator subclass is added that deliberately allows negative cursor.offset slicing. cursors.py receives only comments.
Summary
The optimized path is non-functional and introduces multiple crash regressions. OptimizedCursorPaginator copies the numeric Paginator's key logic but is wired to a DateTimeField (-datetime), so math.floor(datetime) raises TypeError on the first non-empty page; value_from_cursor feeds a raw integer into a datetime-column WHERE clause. The headline "negative offset" feature crashes because Django QuerySet rejects negative slicing. The shared BasePaginator.get_result edit alters every paginator in the codebase, not just the new one, and the authz gate both NPEs on nullable member and is effectively open to every org member.

Verification

Verdict
Recommend changes before merge — the advertised optimization path cannot run without crashing (TypeError on datetime keys, ValueError on negative slicing), and the shared BasePaginator change plus the unguarded member deref introduce regressions to existing endpoints.

🔴 Blocking — shared-code regression & inconsistent clamping. This edit to BasePaginator.get_result affects every paginator subclass (DateTimePaginator, Paginator, etc.), not just the new OptimizedCursorPaginator. The forward path silently clamps negative offsets to 0 (max(0, offset)), which masks malformed/client-crafted cursors that previously raised — a behavior change for all endpoints. The is_prev path still passes a raw (possibly negative) offset straight into queryset[offset:stop], which Django rejects (see the negative-offset finding below). The two branches are inconsistent: forward coerces, prev crashes. Scope this change to the new paginator only, or revert it entirely.

DateTimePaginator.get_item_key avoids this by converting via float(value.strftime("%s.%f")) * multiplier; this class omits that conversion. build_cursor invokes key=self.get_item_key per result row, so the optimized path 500s on the first non-empty page. Subclass DateTimePaginator instead of BasePaginator/Paginator, or replicate the datetime→timestamp conversion.

🔴 Blocking — value_from_cursor returns a raw number for a datetime column. DateTimePaginator.value_from_cursor converts the numeric cursor back to a datetime; this returns cursor.value as-is. build_queryset then builds col >= %s / col <= %s filtering a DateTimeField column against an integer — a DB type mismatch that either errors or silently returns wrong/empty results on every subsequent page. As a side effect, cursors are not interchangeable with DateTimePaginator cursors (which encode datetime*1000), so a client toggling optimized_pagination mid-traversal gets garbage.

Code Review: Enhanced Pagination Performance for High-Volume Audit Logs
Problem
This PR adds an opt-in ?optimized_pagination=true path that routes superusers/global-access members to a new OptimizedCursorPaginator with advertised negative-offset support, aiming to speed up pagination over high-volume audit logs.
Solution Reviewed
The endpoint gains a branch selecting OptimizedCursorPaginator(enable_advanced_features=True) when optimized_pagination=true and the caller is a superuser or has global access; the original DateTimePaginator path otherwise. BasePaginator.get_result offset slicing is modified globally, a new OptimizedCursorPaginator subclass is added that deliberately allows negative cursor.offset slicing, and cursors.py receives only comments.
Summary
This PR is not mergeable. The new paginator cannot function: get_item_key copies the numeric Paginator logic but is wired to a DateTimeField, so math.floor(datetime) raises TypeError on the first non-empty page (reproduced); value_from_cursor feeds a raw integer into a datetime-column WHERE clause, breaking all cursor-based (page 2+) requests; and the headline negative-offset branch crashes because Django QuerySet rejects negative slicing. The admin gate also dereferences a nullable member unconditionally (before the feature gate), regressing the endpoint for system-auth callers with org:write scope. The shared BasePaginator edit alters error semantics for every paginated endpoint. No tests cover any of the new code.

🔴 Blocking — TypeError on every non-empty page.
get_item_key does int(math.floor(value) if ... else math.ceil(value)) directly on getattr(item, self.key). The endpoint uses order_by="-datetime" on AuditLogEntry.datetime, a DateTimeField (confirmed models/auditlogentry.py:69), so value is a datetime. math.floor(datetime) raises TypeError: must be real number, not datetime.datetime (reproduced locally). This is copied from the numeric Paginator, not DateTimePaginator, which converts first via float(value.strftime("%s.%f")) * self.multiplier. build_cursor calls key=self.get_item_key on every result row, so the optimized path 500s the moment it returns any rows.
Fix: subclass DateTimePaginator (or replicate its get_item_key):
def get_item_key(self, item, for_prev=False):
value = getattr(item, self.key)
value = float(value.strftime("%s.%f")) * self.multiplier

🔴 Blocking — cursor round-trip is broken for the datetime column.
value_from_cursor returns cursor.value raw (an int/float parsed from the client cursor string). DateTimePaginator.value_from_cursor converts it back to a datetime via datetime.fromtimestamp(float(cursor.value) / self.multiplier). Without that conversion, build_queryset emits WHERE <table>.datetime <= <number> — comparing a timestamp column to a bare number, which yields wrong/empty results or a DB type error on every cursor-based (page 2+) request. As a side effect, cursors are not interchangeable with DateTimePaginator cursors (which encode datetime*1000), so a client toggling optimized_pagination mid-traversal gets garbage. Reproduced the asymmetry: new class returns raw 1786788000000.0 vs DateTimePaginator decoding back to 2026-08-15 10:00:00+00:00.

🔴 Blocking — negative-offset branch crashes; comments are false.
With enable_advanced_features=True (always true on this path) and cursor.offset < 0, this does list(queryset[start_offset:stop]) with a negative start_offset. Django QuerySet.__getitem__ raises AssertionError("Negative indexing is not supported.") (Django 5.2.1, pinned in requirements-dev-frozen.txt) — it does not "properly handle negative slicing automatically" as the comments on lines 876 and 879 claim. Cursor.from_string parses the client cursor param's offset via int(bits[1]) with no lower-bound validation, so any caller sending e.g. ?optimized_pagination=true&cursor=0:-1:0 triggers an uncaught 500 (Endpoint.paginate only catches BadPaginationError). The advertised performance feature is non-functional and is itself a crash vector.

OrganizationAuditPermission grants access via org:write scope (API keys / integration tokens) OR active superuser (api/bases/organization.py:110-124).

🟡 Non-blocking — off-by-one in the prev-row trim.
elif len(results) == offset + limit + extra uses offset, but the slice was taken with start_offset (stop = start_offset + limit + extra). When start_offset != offset (e.g. a negative non-prev offset clamped to 0 in the else branch), this comparison uses the wrong length and may fail to trim the extra row, returning limit+1 results.

The comment claims this "allows negative offsets for advanced pagination scenarios", but self.offset = int(offset) already accepted negative values before this PR — there is no behavior change here to test or document. Negative-offset enforcement actually lives (inconsistently) in each paginator's get_result. Remove the comment or correct it to avoid implying new functionality.

Code Review: Enhanced Pagination Performance for High-Volume Audit Logs
Problem
The PR attempts to add a high-performance pagination path for the audit-log endpoint, gated on an optimized_pagination=true query param and admin access, via a new OptimizedCursorPaginator.
Solution Reviewed
A new OptimizedCursorPaginator (subclass of BasePaginator) is added with a negative-offset "advanced" branch, and the shared BasePaginator.get_result slicing is modified. The audit-log endpoint branches on optimized_pagination=true + admin access to select the new paginator. Cursor gains only comments.
Summary
The optimized path is non-functional: it crashes with TypeError on any non-empty page because get_item_key applies numeric math.floor/ceil to a datetime. Separately, the endpoint now unconditionally dereferences organization_context.member (nullable), regressing token-auth callers, and the shared base-class slicing change weakens negative-offset safety for every cursor paginator in the codebase. Recommend changes before merge.

Non-blocking: this slicing change is in BasePaginator.get_result, the base for Paginator and DateTimePaginator — so it affects every cursor-paginated endpoint, not just audit logs. Previously a forward cursor carrying a negative offset hit queryset[offset:stop] and raised Django's AssertionError; now max(0, offset) silently clamps it to 0, returning the first page of the value-filtered set instead of erroring. This diverges from the convention that negative offsets are invalid (OffsetPaginator raises BadPaginationError; test_negative_offset asserts it) and can produce duplicate/incorrect pages across many endpoints. The is_prev branch still passes negatives straight to slicing (500), so the two directions are now inconsistent. Prefer validating cursor.offset at the cursor-parse layer and reverting this shared change.

Non-blocking: the gate uses raw request.user.is_superuser, but the endpoint's own permission class (OrganizationAuditPermission, organization.py:124) and the rest of the codebase use is_active_superuser(request), which additionally requires an active superuser session, IP allow-listing, and SSO. A DB is_superuser=True user without an active privileged session could pass this raw-flag gate. Practical impact is limited today (same org-scoped queryset), but it's a latent authorization-convention violation.\n\npython\nfrom sentry.auth.superuser import is_active_superuser\n...\nenable_advanced = is_active_superuser(request) or (\n organization_context.member is not None and organization_context.member.has_global_access\n)\n
