The presence of tabulation and newline in mi is irrelevant and can impact client performance. The parsing & processing of a lot of data from mi with many /t and /n impact performance. This aim to fix the problem at the source. Style is useless for machine. Signed-off-by: Jonathan Rajotte Ju

Hi Jessica, When you say " lttng fails to activate" is it on the lttng add-context command or after looking at the trace ? Can you give us the output from "lttng version"? If possible can you send the complete sequence of action? Thanks On 08/26/2014 11:21 PM, Jessica Foest wrote: > Hi > >
