    perf report: Accept fifos as input file · efad1415
    Robert Richter authored
    The default input file for perf report is not handled the same way as
    perf record does it for its output file. This leads to unexpected
    behavior of perf report, etc. E.g.:
     # perf record -a -e cpu-cycles sleep 2 | perf report | cat
     failed to open perf.data: No such file or directory  (try 'perf record' first)
    While perf record writes to a fifo, perf report expects perf.data to be
    read. This patch changes this to accept fifos as input file.
    Applies to the following commands:
     perf annotate
     perf buildid-list
     perf evlist
     perf kmem
     perf lock
     perf report
     perf sched
     perf script
     perf timechart
    Also fixes char const* -> const char* type declaration for filename
    * Prevent potential null pointer access to input_name in
      builtin-report.c. Needed due to removal of patch "perf report: Setup
      browser if stdout is a pipe"
