      perf ui browser: Allow overriding refresh_dimensions method · fa70b5d6
      由 Arnaldo Carvalho de Melo 提交于 
      Some browsers, like the hist_browser, may want to be notified everytime
a refresh_dimensions is needed, so that it can reset ui_browser->rows,
for instance, or do some other related reaction to screen resizings.

      perf ui browser: Add ->rows to disambiguate from ->height · 62c95ae3
      由 Arnaldo Carvalho de Melo 提交于 
      The ui_browser->height is about the whole browser "window", including
any header, status lines or any other space needed for some "Yes", "No",
etc buttons a descendent browser, like hist_browser, may have.

Since the navigation is done mostly on the ui_browser methods, it needs
to know how many rows are on the screen, while details about what other
components are, say, if a header (that may be composed of multiple
lines, etc) is present.

Besides this we'll need to add a ui_browser->refresh_dimensions() hook
so that browsers like hist_browser can update ->rows in response to
screen resizes, this will come in a follow up patch.

This patch just adds ->rows and updates it when updating ->height, keeps
using ->height for the only other widget that can come with ui_browser,
the scrollbar, that goes on using all the height on the rightmost column
in the screen, using ->rows for the keyboard navigation needs.

      perf tools: Use __maybe_used for unused variables · 1d037ca1
      由 Irina Tirdea 提交于 
      perf defines both __used and __unused variables to use for marking
unused variables. The variable __used is defined to
__attribute__((__unused__)), which contradicts the kernel definition to
__attribute__((__used__)) for new gcc versions. On Android, __used is
also defined in system headers and this leads to warnings like: warning:
'__used__' attribute ignored

__unused is not defined in the kernel and is not a standard definition.
If __unused is included everywhere instead of __used, this leads to
conflicts with glibc headers, since glibc has a variables with this name
in its headers.

The best approach is to use __maybe_unused, the definition used in the
kernel for __attribute__((unused)). In this way there is only one
definition in perf sources (instead of 2 definitions that point to the
same thing: __used and __unused) and it works on both Linux and Android.
This patch simply replaces all instances of __used and __unused with
__maybe_unused.

      由 Arnaldo Carvalho de Melo 提交于 
      Simple algorithm, just look for the next backward jump that points to
before the cursor.

Then draw an arrow connecting the jump to its target.

Do this as you move the cursor, entering/exiting possible loops.

      perf hists browser: Recalculate browser pointers after resort/decay · 900e14a8
      由 Arnaldo Carvalho de Melo 提交于 
      In browsers that access dynamic underlying data structures, like in the
hists browser and its hist_entry rb_tree, we need to revalidate any
reference to the underlying data structure, because they can have gone
away, decayed.

This fixes a problem where after a while the top entries get behind the
top of the screen, i.e. the top_idx stays at 0, which means it is at the
first entry in the rb_tree when in fact it wasn't because the
browser->top didn't got revalidated after the timer ran and the
underlying data structure got updated.

      perf ui browser: Introduce ui_browser__show_title · b210b3bb
      由 Arnaldo Carvalho de Melo 提交于 
      Needed because we were only showing the title in ui_browser__show,
not in ui_browser__run, and in the run loop we may be calling other
browsers that would then change the title, when we go back to the
previous browser, we need to redraw the title.

We could have done this as the Newt help line, with pop, etc, but I
don't think its worth, doing it explicitely, when needed (some browsers
may not use the title area at all) seems enough/more flexible.

      由 Arnaldo Carvalho de Melo 提交于 
      The ui operations so far were used by just one thread, but 'perf top
--tui' now has two threads updating the screen, so we need to use a
mutex to avoid garbling the screen.

      We wrap it in libslang.h because we need to deal with older slang release
where HAVE_LONG_LONG is referenced as:

So we need to define it.

      They are useless and take away precious columns and lines, so stop using
windows.

One more step in removing newt code, that after all is not being useful
at all for the coalescing TUI model in perf.
