fix(error-tracking): query issues by severity by hpouillot · Pull Request #86409 · PostHog/posthog

hpouillot · 2026-08-20T12:30:22Z

Problem

Issue queries cannot return or filter assigned severity.

The query state types accept severity, but HogQL does not read the fingerprint state field.

PR stack

Merge in this order:

Depends on: #83107

Followed by: #86410

Changes

Issue queries return assigned severity from optimized and legacy query shapes.
Severity filters support exact values, set values, and unset values.
Pending issue updates preserve severity while ClickHouse catches up.
Query snapshots and the cache version change mechanically.
No visual changes.

How did you test this code?

The pending-state and severity-filter regression cases passed.
Not run to completion: the full query suite hit a local ClickHouse open-file limit after the changed cases passed.
Ruff passed on the changed Python files.

👉 Stay up-to-date with PostHog coding conventions for a smoother review.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Pi split the existing severity change into a focused HogQL layer under human direction.

Skills invoked: /stacking-prs, /writing-tests, /writing-code-comments, /writing-simplified-technical-english, and /writing-pr-descriptions.

Add severity to generated issue query models and pending state updates so later query execution changes can consume it safely. Generated-By: PostHog Desktop Task-Id: 543f7db8-9779-4818-8a8a-2e060579439a

Expose severity through the fingerprint state join, return it from both query shapes, and support exact and presence filters. Generated-By: PostHog Desktop Task-Id: 543f7db8-9779-4818-8a8a-2e060579439a

Hey @hpouillot! 👋

It looks like your git author email on this PR isn't your @posthog.com address (hpouillot@gmail.com). Since you're on the PostHog team, it's worth pointing your local git author email at your @posthog.com address. Why it matters:

Consistent work identity in git history — internal tooling that attributes commits to team members keys off your @posthog.com address.
Keeps team contributions easy to tell apart from external community ones when scanning history.

You can fix it for this repo with:

git config user.email "you@posthog.com"

Or set it globally with git config --global user.email "you@posthog.com". No need to redo this PR — just a nudge for next time. 🙂

✅ Toolbar bundle — eager 2.24 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

Metric	Size	Δ vs base	Budget
Eager (shipped) entry + static imports	2.24 MiB · 17 files	no change	`████░░░░░░` 39.1% of 5.72 MiB

_{Reviews (1): Last reviewed commit: "Merge branch 'hp/error-tracking-severity..." | Re-trigger Greptile}

stamphog

Adds a nullable, backward-compatible severity field across the error-tracking query schema, filters, and pending-update reconciliation logic; the bulk of the diff is mechanical (generated schema/snapshot files), the hand-written logic is small and covered by new tests (exact/is_set/is_not_set filter cases, pending-update constant assertion), and the description accurately matches the diff with no undisclosed behavior.

Author wrote 10% of the modified lines and has 109 merged PRs in these paths (familiarity MODERATE).
