Priority: Minor
Fix For: 0.26.0
When check the perf version with the "perf::version" gets the command output
"perf --version". The command return string includes a "return key". It cause
the version parse fails. If add the strings::trim, the issue is fixed.
The old code:
Future<Version> version()
{
internal::Perf* perf = new internal::Perf({"--version"});
Future<string> output = perf->output();
spawn(perf, true);
return output
.then([](const string& output) -> Future<Version> {
// Trim off the leading 'perf version ' text to convert.
return Version::parse(strings::remove(
output, "perf version ", strings::PREFIX));
});
};
