[PATCH 0/1] perf script python: Garbled text in tracepoint fields

Show all headers | View raw

The string stored in some of the fields of tracepoint handlers has unused non-ascii characters beyond the first null ternimating character. As a result the call to is_printable_array fails and the python handlers receive the entire field as a byte array instead of just the subset of chars that represent the string.

This change calls is_printable_array with the correct length of the string instead of the entire field size.
