// Says whether a push to main brings release commits alone (exit 0) or
|
||
|
|
// anything else (exit 1), for tool/pre-push, which then skips the checks: a
|
||
|
|
// release commit changes an app's version and its texts of what's new alone
|
||
|
|
// (tool/src/release/release_push.dart says why that is enough). Reads what
|
||
|
|
// git hands a pre-push hook: the remote as the argument, a line per ref pushed
|
||
|
|
// on stdin (local ref, local commit, remote ref, remote commit), and looks at
|
||
|
|
// the commits pushed to main that no ref of that remote has yet, as
|
||
|
|
// tool/check_signatures.sh does.
