#1288157 — [PATCHSET 0/7] perf tools: Remove browser dependency from usage_with_options()

Hello,

This patchset removes the UI browser dependency (specifically
exit_browser function) from option parser code.  It'll help to
separate out the common code into a library.

Now existing users of usage_with_options() were converted to call it
before setup_browser().  I think future users can notice the
difference when they test their code and will call it properly.

It's available on 'perf/option-dependency-v1' branch on my tree

  git://git.kernel.org/pub/scm/linux/kernel/git/namhyung/linux-perf.git

Thanks
Namhyung

#1288158 — [PATCH 5/7] perf top: Delay UI browser setup after initialization is done

Move setup_browser after all necessary initialization is done.  This
is to remove the browser dependency from usage_with_options() and
friends.

#1288747 — Re: [PATCH 5/7] perf top: Delay UI browser setup after initialization is done

So, please try:

perf top -C 0 -p 1

So that we get a command line validation error that will cause cmd_top
to trip this:

        status = target__validate(target);
        if (status) {
                target__strerror(target, status, errbuf, BUFSIZ);
                ui__warning("%s\n", errbuf);
        }

ui__warning() will emit the warning to stdio, and this message will be
seen only after the user exits the tool:

[root@ssdandy ~]# perf top -C 0 -p 1
Warning:
PID/TID switch overriding CPU

Where without this patch the user will be warning with a popup window,
that has to be acknowledged with an enter before proceeding.

Looking at the other patches to check which can be processed now,
leaving this one for later.

So, this one should be enough, ack?

Subject: [PATCH] perf report: Do show usage message when failing to create
 cpu/thread maps

This is necessary to get rid of the browser dependency from
usage_with_options() and its friends.  Because we validate the targets
which are used to create the cpu/thread maps and inform the user about
any override performed via the chosen UI, we don't need to call the
usage routine for that.

#1288160 — [PATCH 3/7] perf kvm: Remove invocation of setup/exit_browser()

Calling setup_browser(false) with use_browser = 0 is meaningless.
Just get rid of it.  This is necessary to remove the browser
dependency from usage_with_options() and friends.

#1288166 — [PATCH 1/7] perf annotate: Check argument before calling setup_browser()

This is necessary to get rid of the browser dependency from
usage_with_options() and its friends.  Because there's no code
changing the argc and argv, it'd be ok to check it early.

So, applied all except for the top one, that I rewrote as reported,
pushed to perf/core, the replaced patch is this one:
