URL: https://github.com/llvm/llvm-project/commit/90c5675a3db2319dd449a1753c79568355dfaaed DIFF: https://github.com/llvm/llvm-project/commit/90c5675a3db2319dd449a1753c79568355dfaaed.diff LOG: [lldb][NFCI] Rewrite error-handling code in ProcessGDBRemote::MonitorDebugserverProcess I'm rewriting this for 2 reasons: 1) Although a 1024 char buffer is probably enough space, the error string may grow beyond that and we could lose some information. Using StringStream (as we do in the rest of ProcessGDBRemote) seems like a sensible solution. 2) I am planning on changing `UnixSignals::GetSignalAsCString`, rewriting things with `llvm::formatv` will make that process easier.
