What

Add a migration test for a refutation game occurring on a DAL_page_import.

Closes #8156.

Why

To test this specific case.

Manually testing the MR

The new test can be launched with:

make && dune exec tezt/tests/main.exe -- --verbose --log-file /tmp/$(date "+%Hh%M").log --file tezt/tests/dal.ml --title "T024->Alpha: refutation game over DAL page import across protocol migration"

I’m not sure about the format. I think it makes sense, but it does not play well with nested calls. Could we add a innerTraces maybe?

Hello @NicVolanschi , thanks for the suggestion.

grafazos-multi-exporters is now rebased on origin/comeh@grafazos-nodeexporter (!20470)

Let's not use the CRAC acronym in user facing naming. I think you could copy the naming and behavior of debug_trace*, but replace debug with http or tezosx.

http_traceBlock, http_traceCall, http_traceTransaction etc.

Summary

The tezt and etherlink.tezt jobs are currently the dominant contributor to pipeline wall-clock time on the before_merging pipeline.

This MR attempt to find the best their parallel: node count and tezt internal parallel mechanism.

Motivation

Faster feedback on MRs, the two jobs currently dominate the critical path:

Change (WIP)

Double the parallel: count for both jobs:

TEZT_PARALLEL (in-node concurrency) is left unchanged (WIP)

Why this is cost-neutral

Tezt distributes tests across nodes using pre-recorded timing data (tezt/records/), so doubling nodes halves the test slice per node and therefore halves the per-node runtime. Total cost is:

total_node_minutes = parallel × mean_duration

Doubling parallel while halving mean_duration keeps total_node_minutes constant.

fixed : added filter on label dimension = "reads" or "writes", thanks for the suggestion.
