perf: Only include annotate.h once in tools/perf/util/ui/browsers/annotate.c

2011-05-10T08:20:07+00:00

Including "../../annotate.h" once in
tools/perf/util/ui/browsers/annotate.c is enough. No need to do it twice.

perf hists browser: Fix seg fault when annotate null symbol

2011-04-15T15:51:49+00:00

In hists browser, press hotkey 'a' to annotate current symbol.

Now it causes segment fault if 'a' is pressed on a null symbol.

Here are 2 small bugs:
- In perf_evsel__hists_browse, the condition check after 'a' is pressed
  is not correct, we should check ->sym instead of ->map.
- In symbol__tui_annotate we must check whether sym is NULL or not
  before getting annotation structure.

This patch fixes above 2 small bugs.

perf report tui: Improve multi event session support

2011-03-06T16:14:53+00:00

When multiple events were used in 'perf record', allow the user to
choose which one is wanted before showing the per event histograms.

Annotations will be performed on the chosen event.

Allow going back and forth from event to event quickly using just the
arrow keys and enter.

perf tools: Improve support for sessions with multiple events

2011-03-06T16:13:40+00:00

By creating an perf_evlist out of the attributes in the perf.data file
header, so that we can use evlists and evsels when reading recorded
sessions in addition to when we record sessions.

More work is needed to allow tools to allow the user to select which
events are wanted when browsing sessions, be it just one or a subset of
them, aggregated or showed at the same time but with different
indications on the UI to allow seeing workloads thru different views at
the same time.

But the overall goal/trend is to more uniformly use evsels and evlists.

perf report tui: Fix multi event switching

2011-03-06T01:31:04+00:00

TAB/UNTAB were not hotkeys, so didn't exit hists__browse back to
hists__tui_browse_tree, allowing just the first event to be browsed.

perf tui: Make ui__warning modal

2011-03-01T13:24:43+00:00

By taking the ui__lock so that no other screen updates take place while
waiting for the user.

That was happening when handling an invalid --vmlinux parameter in 'perf
top --tui', with the screen refresh routine repainting the screen and
removing the warning window.

perf top browser: Handle empty active symbols list

2011-03-01T13:21:44+00:00

Fixing a SEGV. An empty list could happen when not being able to resolve
symbols, for instance when --vmlinux invalid-file is used.

perf ui browser: Introduce ui_browser__show_title

2011-02-25T14:33:31+00:00

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.
