fix(ci): avoid SIGPIPE noise polluting semver-level JSON output by iunanua · Pull Request #2157 · DataDog/libdatadog

iunanua · 2026-06-24T15:15:25Z

Problem

The semver-level CI step was failing with:

.../semver-level.sh: line 125: echo: write error: Broken pipe
.../semver-level.sh: line 142: echo: write error: Broken pipe
{ ...valid JSON... }
jq: parse error: Invalid numeric literal at line 1, column 57

The semver level was computed correctly (minor), but the downstream jq step crashed.

Root cause

scripts/semver-level.sh used echo "$VAR" | grep -q ... on large variables (the full cargo public-api diff). grep -q exits on the first match, closing the pipe before echo finishes writing, so bash emits echo: write error: Broken pipe to stderr.

The workflow captures the script's combined stdout+stderr and pipes it into jq. Those two stderr lines land on top of the JSON, and jq dies parsing .../semver-level.sh: line 125: at column 57 (right after the 56-char script path).

Fix

Replace every echo "$VAR" | grep pipeline with a here-string (grep ... <<< "$VAR"). Here-strings buffer the whole input, so an early grep -q/head exit no longer triggers SIGPIPE — no spurious stderr to pollute the workflow's captured stream.

🤖 Generated with Claude Code

Replace 'echo "$VAR" | grep' pipelines with here-strings. With large public-api diffs, 'grep -q' exits on first match and closes the pipe before echo finishes, emitting 'echo: write error: Broken pipe' to stderr. The workflow captures combined stdout+stderr and pipes it to jq, which then chokes on the broken-pipe lines. Here-strings buffer the input, so early grep exit no longer triggers SIGPIPE.
