[lldb-dev] gdb-remote logging question

ProcessGDBRemoteLog::GetLogIfAllCategoriesSet() is for logging specific the GDB remote plug-in used with:

(lldb) log enable gdb-remote ...

GetLogIfAnyCategoriesSet(...) is used when doing generic LLDB logging:

(lldb) log enable lldb process ...

So use the latter for generic process plug-in logging (like launching, attaching, etc). Then for packet stuff or other things specify only to the GDB remote part in the former.

And got confused by logging style mixture - sometimes gdb-remote channel logging is used (via ProcessGDBRemoteLog::GetLogIfAllCategoriesSet(GDBR_LOG_,...)) or more often lldb channel is utilized (GetLogIfAnyCategoriesSet(LIBLLDB_LOG_....)).

As I can see lldb-gdbserver (cannot say for OSX debugserver and lldb-platform) allows to save log output as a file only for gdb-remote channel and lldb channel has no chance to be saved anywhere .
