Sync run.sh and run.cmd options with run.py by Copilot · Pull Request #125511 · dotnet/runtime

Copilot · 2026-03-12T21:49:30Z

Description

run.sh and run.cmd were missing several options accepted by run.py, and run.sh had a bug where it passed --tieringtest to run.py which only recognizes --tiering_test (causing the argument to be silently ignored or fail). Additionally, several flags accepted by both scripts were missing from their help menus, one option was intentionally hidden, and Composite mode was only available via environment variable but not exposed through the scripts.

`run.sh`

Bug fix: --tieringtest → --tiering_test when forwarding to run.py
Added: --parallel=<type> option (none, collections, assemblies, all) — already present in run.cmd, missing from run.sh
Added: --runlargeversionbubblecrossgen2tests — sets RunCrossGen2=1 and forwards --large_version_bubble to run.py; already in run.cmd, missing from run.sh
Added: --composite — forwards --composite to run.py to enable Crossgen2 composite mode
Help fix: Added description for --limitedDumpGeneration (previously had an empty description)

`run.cmd`

Added: verbose — passes --verbose to run.py; already in run.sh, missing from run.cmd
Added: limitedDumpGeneration — passes --limited_core_dumps to run.py; already in run.sh, missing from run.cmd
Added: composite — passes --composite to run.py to enable Crossgen2 composite mode
Help fix: Added tieringtest, runnativeaottests, runlargeversionbubblecrossgen2tests, and composite to the help menu — they were accepted by the argument parser but not documented
Help fix: Fixed alignment of verbose, limitedDumpGeneration, interpreter, and node entries in the help section
Removed: "intentionally undocumented" comment for runlargeversionbubblecrossgen2tests; option is now documented as experimental

`run.py`

Added: --composite argument — sets CompositeBuildMode=1 environment variable, matching the pattern used in helixpublishwitharcade.proj for Helix test runs

Changes

src/tests/run.sh

@copilot make sure all the flags that are accepted are in the help menus too.

@copilot make sure all the flags that are accepted are in the help menus too.

Done in b79eb42:

Added tieringtest and runnativeaottests to the run.cmd help menu (they were accepted but undocumented)
Fixed the empty description for --limitedDumpGeneration in run.sh
Fixed alignment of the newly added entries in run.cmd's help section

jtschuster · 2026-03-12T23:21:20Z

@copilot Add the runlargeversionbubblecrossgen2tests option and remove the "intentionally hidden" comment. Just leave a note that it's experimental. I don't see why we should have any undocumented options.

Done in 2c43f5e — removed the "intentionally undocumented" comment and added runlargeversionbubblecrossgen2tests to the help menu marked as (Experimental).

    echo '  --interpreter                    : Runs the tests with the interpreter enabled'
    echo '  --node                           : Runs the tests with NodeJS (wasm only)'
-    echo '  --limitedDumpGeneration          : '
+    echo '  --limitedDumpGeneration          : Limits the number of core dumps generated for this test run'


@copilot Don't we need largeversionbubblecrossgen2tests here too? And I don't think Composite mode is in run.py, but is in the test runners via an environment variable. We should add it to run.py and run.sh and run.cmd.

Done in 9f41b7c:

Added --runlargeversionbubblecrossgen2tests to run.sh (argument parsing, help menu, forwarding --run_crossgen2_tests + --large_version_bubble to run.py)

Added --composite to run.py (sets CompositeBuildMode=1 env var, matching helixpublishwitharcade.proj)

Added --composite to run.sh and composite to run.cmd (both forward --composite to run.py)

All three entries documented in their respective help menus as (Experimental)
