docs(test): pin the celeris source references in the h2c matrix to v1.5.11 by FumingPower3925 · Pull Request #111 · goceleris/loadgen

FumingPower3925 · 2026-10-09T15:43:16Z

What

Comment-only update to integration_h2c_test.go, plus one skip-reason string (below). The comments cite celeris source by path and line number. They now name the celeris version, the file and the function.

Why

goceleris/celeris#443 (merged as goceleris/celeris#938, 21d49ef) moved engine/, resource/ and the other codec packages under internal/. loadgen's internal/integrationtest/testserver is pinned to celeris v1.5.11, which still has the old paths, so the comments are right for the pin and wrong for celeris main.

Findings:

loadgen has no dependency on a moved package. The only celeris import in the repo is the public root package github.com/goceleris/celeris in internal/integrationtest/testserver/main.go.
The cited paths are generic claims about the pinned version, so I made them version-explicit ("celeris v1.5.11 resource/config.go") rather than repointing them to internal/ paths that do not exist at the pin.
The line numbers were wrong even at v1.5.11 (resource/config.go:167-169 is at 187-188, internal/conn/h1.go "line 536" is tryUpgradeH2C at 824, config.go:210-215 is at 289-293, engine/iouring/worker.go:782-794 is at 1249-1260). I replaced them with function names, each checked against the v1.5.11 tag.
A header note says that the two moved roots resolve only at the pinned tag and need a fresh look when the pin moves.

Scope

Only integration_h2c_test.go. The one non-comment edit is the autoCoercesUpgrade string constant, which shows up in -v skip output; no test logic, matrix cell or build tag changes. No repin.

Checks

The file carries the integration build tag, so only the integration matrix job in ci.yml compiles and runs it.

….5.11 The comments in integration_h2c_test.go cite celeris source by path and line number. The paths are right for the pinned celeris v1.5.11 but engine/ and resource/ moved under internal/ on celeris main, and the line numbers were already stale at v1.5.11. Name the version, the file and the function instead, and say why the two moved paths do not resolve on main. The skip-reason string for the Auto rows gets the same wording.

Linked repositories findings

goceleris/celeris

The pinned v1.5.11 tag exists at commit 1ff8feb.... Its tree contains engine/epoll/loop.go, engine/iouring/worker.go, and protocol/h2/stream/processor.go; these paths are absent from main, where they moved under internal/engine and internal/protocol. [::goceleris/celeris::]
The cited functions are present at v1.5.11: switchToH2 in both engine implementations, InjectStreamHeaders in the H2 processor, and tryUpgradeH2C in internal/conn/h1.go. [::goceleris/celeris::]
The current Celeris implementation confirms these functions govern the H1→H2C handoff, stream-1 injection, and residual-preface processing, so pinning the comments to v1.5.11 is materially important. [::goceleris/celeris::]

goceleris/probatorium

The repository’s validation harness directly exercises h2c upgrade behavior through validation/h2c.go, including construction of the RFC h2c upgrade preamble and classification of upgraded, declined, crashed, and hung outcomes. [::goceleris/probatorium::]
No exported API, dependency, or runtime contract is affected by the described comment-only changes.

Align the deferred-commit attribution with v1.5.11.

The file header defines all Celeris references below as v1.5.11, but this explanation still attributes the behavior to v1.4.1. This leaves the cited behavior tied to a different version than the referenced source. Update the attribution.

Suggested fix

- // In celeris v1.4.1 the native engines defer the protocol commit + // In celeris v1.5.11 the native engines defer the protocol commit
