perf help: Use asprintf instead of adhoc equivalents

2016-03-23T19:36:07+00:00

That doesn't chekcs malloc return and that, when using strbuf, if it can't grow, just explodes away via die(). Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-vr8qsjbwub7e892hpa9msz95@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf config: Bring perf_default_config to the very beginning at main()

2016-02-26T22:49:16+00:00

Before this patch each subcommand calls perf_config() by themself, reading the default configuration together with subcommand specific options. If a subcommand doesn't have it own options, it needs to call 'perf_config(perf_default_config, NULL)' to ensure .perfconfig is loaded. This patch brings perf_config(perf_default_config, NULL) to the very start of main(), so subcommands don't need to do it. After this patch, 'llvm.clang-path' works for 'perf trace'.

perf help: No need to use strbuf_remove()

It is the only user of this function, just use the strlen() to skip the prefix. Cc: Adrian Hunter Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-blao710l5cd5hmwrhy51ftgq@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf subcmd: Create subcmd library

2015-12-17T17:27:14+00:00

Move the subcommand-related files from perf to a new library named libsubcmd.a. Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to 'exec-cmd.*' to be consistent with the naming of all the other files.

perf help: Change 'usage' to 'Usage' for consistency

perf tools: Add the bash completion for listing subsubcommands of perf help

2015-03-19T16:49:39+00:00

The bash completion does not support listing subsubcommands for 'perf help ', so fix it. Example: Before this patch: $ perf help $ As shown above, the subsubcommands of perf help does not come out. After this patch: $ perf help annotate buildid-cache data evlist inject kvm lock probe report script test top bench buildid-list diff help kmem list mem record sched stat timechart trace As shown above, the subsubcommands of perf help can come out now.

perf help: Fix --help for builtins

2012-10-22T14:35:49+00:00

It seems that commit cc5848213329 ("perf help: Remove use of die and handle errors") caused the problem - it changed the initial value of 'help_format' from HELP_FORMAT_MAN to HELP_FORMAT_NONE. This broke the --help option for all builtins, that would produce no output, while 'man perf-top' would work it MANPATH is properly setup.
