Ports sveltekit-2, sveltekit-2-kit-tracing, sveltekit-2-svelte-5, sveltekit-2.5.0-twp, sveltekit-3 and sveltekit-cloudflare-pages to span streaming, and adds sveltekit-2-static as a verbatim copy of the old sveltekit-2 (only the app name changed) to keep the static trace lifecycle covered.

Decisions taken while porting:

  • Under streaming the browser's pageload segment is parented to the server's sveltekit.resolve span, so the whole request shares one trace. The kit-tracing and SvelteKit 3 specs use a small getSegmentChildSpans helper that walks a segment's descendants without crossing into other segments, which keeps the exact child-span count assertions meaningful.
  • SvelteKit router spans are now named Router, browser fetch spans GET localhost, and mysql spans carry the query summary (SELECT) as name with the full text in db.query.text. Specs assert the new names and keep the old details as attributes.
  • On Cloudflare Pages the outermost segment is the @sentry/cloudflare request span (GET, source url); the SvelteKit GET /db-mysql span is its child. The db specs match on the trace instead of a transaction name.
  • The request assertions on server transactions have no streamed equivalent and became assertions on http.request.method and http.request.header.* attributes.
  • The skipped SvelteKit 3 form-action test stays skipped with its FIXME.

l: do we collect a code.function.name attribute for this as well? We still need to create function span name and description rules and I think we basically want to infer names based on the function name, so this needs to land in an attribute in addition to the span name.

If we don't, this is out of scope and should be tackled via #23954

this is a good observation. Maybe we need some kind of helper that waits for an entire segment (across envelopes) but drops spans not belonging to the segment 🤔 This would avoid having to add this kind of function to meta framework e2e tests.

l: do we collect a code.function.name attribute for this as well? We still need to create function span name and description rules and I think we basically want to infer names based on the function name, so this needs to land in an attribute in addition to the span name.

If we don't, this is out of scope and should be tackled via #23954

this is a good observation. Maybe we need some kind of helper that waits for an entire segment (across envelopes) but drops spans not belonging to the segment 🤔 This would avoid having to add this kind of function to meta framework e2e tests.

Ports sveltekit-2, sveltekit-2-kit-tracing, sveltekit-2-svelte-5, sveltekit-2.5.0-twp, sveltekit-3 and sveltekit-cloudflare-pages to span streaming, and adds sveltekit-2-static as a verbatim copy of the old sveltekit-2 (only the app name changed) to keep the static trace lifecycle covered.

Decisions taken while porting:

  • Under streaming the browser's pageload segment is parented to the server's sveltekit.resolve span, so the whole request shares one trace. The kit-tracing and SvelteKit 3 specs use a small getSegmentChildSpans helper that walks a segment's descendants without crossing into other segments, which keeps the exact child-span count assertions meaningful.
  • SvelteKit router spans are now named Router, browser fetch spans GET localhost, and mysql spans carry the query summary (SELECT) as name with the full text in db.query.text. Specs assert the new names and keep the old details as attributes.
  • On Cloudflare Pages the outermost segment is the @sentry/cloudflare request span (GET, source url); the SvelteKit GET /db-mysql span is its child. The db specs match on the trace instead of a transaction name.
  • The request assertions on server transactions have no streamed equivalent and became assertions on http.request.method and http.request.header.* attributes.
  • The skipped SvelteKit 3 form-action test stays skipped with its FIXME.

Ports sveltekit-2, sveltekit-2-kit-tracing, sveltekit-2-svelte-5, sveltekit-2.5.0-twp, sveltekit-3 and sveltekit-cloudflare-pages to span streaming, and adds sveltekit-2-static as a verbatim copy of the old sveltekit-2 (only the app name changed) to keep the static trace lifecycle covered.

Decisions taken while porting:

  • Under streaming the browser's pageload segment is parented to the server's sveltekit.resolve span, so the whole request shares one trace. The kit-tracing and SvelteKit 3 specs use a small getSegmentChildSpans helper that walks a segment's descendants without crossing into other segments, which keeps the exact child-span count assertions meaningful.
  • SvelteKit router spans are now named Router, browser fetch spans GET localhost, and mysql spans carry the query summary (SELECT) as name with the full text in db.query.text. Specs assert the new names and keep the old details as attributes.
  • On Cloudflare Pages the outermost segment is the @sentry/cloudflare request span (GET, source url); the SvelteKit GET /db-mysql span is its child. The db specs match on the trace instead of a transaction name.
  • The request assertions on server transactions have no streamed equivalent and became assertions on http.request.method and http.request.header.* attributes.
  • The skipped SvelteKit 3 form-action test stays skipped with its FIXME.

l: do we collect a code.function.name attribute for this as well? We still need to create function span name and description rules and I think we basically want to infer names based on the function name, so this needs to land in an attribute in addition to the span name.

If we don't, this is out of scope and should be tackled via #23954

this is a good observation. Maybe we need some kind of helper that waits for an entire segment (across envelopes) but drops spans not belonging to the segment 🤔 This would avoid having to add this kind of function to meta framework e2e tests.

this still needed a conventions entry. Added here: getsentry/sentry-conventions#611, along with a few other attributes also found in other tests

op: 'function',
description: 'sveltekit.resolve',
origin: 'auto.http.sveltekit',
name: 'sveltekit.resolve',

l: do we collect a code.function.name attribute for this as well? We still need to create function span name and description rules and I think we basically want to infer names based on the function name, so this needs to land in an attribute in addition to the span name.

If we don't, this is out of scope and should be tackled via #23954

thx for checking. Fine for now!

* `sveltekit.resolve` span and therefore shares the trace with the server request. Stopping at
* segment boundaries keeps assertions on the server request's child spans free of browser spans.

this is a good observation. Maybe we need some kind of helper that waits for an entire segment (across envelopes) but drops spans not belonging to the segment 🤔 This would avoid having to add this kind of function to meta framework e2e tests.

'db.operation.name': { value: 'set', type: 'string' },
'db.query.text': { value: 'set test-key [1 other arguments]', type: 'string' },

heads-up: This PR needs a rebase and adjustments here because redis span names have changed via #23741

Replaces the per-app getSegmentChildSpans tree walk in the SvelteKit specs with a shared
collector that groups streamed spans by their segment id.
