Fix GitHub Actions output parsing in sync workflow#78
Merged
Conversation
Under set -euo pipefail, git rev-list | head -1 causes SIGPIPE when head closes the pipe before git finishes writing. Fix: capture full output into a variable, use here-strings to extract the first line and count. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
The sync script output may contain \r\n line endings, causing classification=build-changes\r to be written to GITHUB_OUTPUT. GitHub Actions rejects this as invalid format. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

The sync script output may contain \r\n line endings, causing values like
classification=build-changes\rto be written to$GITHUB_OUTPUT. GitHub Actions rejects this asInvalid format 'build-changes'.Fix: add
tr -d '\r'when parsing Branch, Classification, and PR fields from script output.
