Bug in LLDB RSP client causes '$O' packets to be decoded incorrectly

Authored by evgeny777 on Sep 1 2015, 3:52 AM.



Character with ASCII code 0 is incorrectly treated by LLDB as the end of RSP packet. The left of the debugger server output is silently ignored.

Why did we introduce StringExtractor::GetHexU8Ex() if the only place that calls it is StringExtractor::GetHexU8() and other places that should just call StringExtractor::GetHexU8()? Seems like you should just fix StringExtractor::GetHexU8() to contain the contents of StringExtractor::GetHexU8Ex() and get rid of StringExtractor::GetHexU8Ex().

GetHexU8Ex is called from SendContinuePacketAndWaitForResponse() in GDBRemoteCommunicationClient.cpp. Please take a look at the patch

Ah yes, just the fail_value is the difference.
