perf tools: Rename struct perf_data_file to perf_data

2017-10-30T16:36:09Z

Rename struct perf_data_file to perf_data, because we will add the possibility to have multiple files under perf.data, so the 'perf_data' name fits better.

perf tools: Fix leaking rec_argv in error cases

2017-09-18T12:40:21Z

Let's free the allocated rec_argv in case we return early, in order to avoid leaking memory. This adds free() at a few very similar places across the tree where it was missing.

perf tools: Use just forward declarations for struct thread where possible

2017-04-24T16:43:35Z

Removing various instances of unnecessary includes, reducing the maze of header dependencies. Link: http://lkml.kernel.org/n/tip-hwu6eyuok9pc57alookyzmsf@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf str{filter,list}: Disentangle headers

2017-04-19T16:01:52Z

There are places where we just need a forward declaration, and others were we need to include strlist.h and/or strfilter.h, reducing the impact of changes in headers on the build time, do it.

perf tools: Include errno.h where needed

2017-04-19T16:01:51Z

Removing it from util.h, part of an effort to disentangle the includes hell, that makes changes to util.h or something included by it to cause a complete rebuild of the tools.

perf tools: Including missing inttypes.h header

2017-04-19T16:01:46Z

Needed to use the PRI[xu](32,64) formatting macros. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-wkbho8kaw24q67dd11q0j39f@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Add include where ARRAY_SIZE() is used

2017-04-19T16:01:44Z

To pave the way for further cleanups where linux/kernel.h may stop being included in some header. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-qqxan6tfsl6qx3l0v3nwgjvk@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Remove unused 'prefix' from builtin functions

2017-03-27T14:58:09Z

We got it from the git sources but never used it for anything, with the place where this would be somehow used remaining: static int run_builtin(struct cmd_struct *p, int argc, const char **argv) { prefix = NULL; if (p->option & RUN_SETUP) prefix = NULL; /* setup_perf_directory(); */ Ditch it.

perf timechart: Use OPT_PARENT for common options

2017-03-17T14:49:08Z

Move -T/--tasks-only and -P/--power-only options to a separate options array that then gets referenced via OPT_PARENT from the 'perf timechart' and 'perf timechart record' option arrays.
