Don't force RUST_BACKTRACE=1 on remote runs - #264
Merged
Conversation
The ssh and android runners hardcoded RUST_BACKTRACE=1 into the remote command, forcing a backtrace capture on every error in the run — cheap on most hosts but pathologically slow on constrained targets (a static musl aarch64 board can spend seconds per capture), which dominated cross-run time. Drop it; callers that want backtraces can still pass -e RUST_BACKTRACE=1.
