2011-10-26perf ui: Improve handling sigwinch a bitArnaldo Carvalho de Melo5-47/+82
No need to unblock it at each ui__getch() and also allow other users to check if a resize is needed, or force an refresh of terminal dimensions. The 'force' one shouldn't be needed, but its in a slow path, so leave it like that for now, I'll revisit this another day.

2011-10-14perf hists browser: Invalidate ui_browser->top after timer callsArnaldo Carvalho de Melo2-2/+14
With underlying dynamic data structures we need to invalidate pointers to them after a timer, as that entry may have vanished (decayed in top, for instance). I forgot about browser_ui->top. Fix it by resetting it to null after a timer. The seek operation from SEEK_SET will then set it to a valid entry because it starts from rb_first(&hists->entries).

2011-10-13perf hists browser: Fix handling of TAB/UNTAB for multiple eventsArnaldo Carvalho de Melo1-17/+31
When using multiple events the 'top' and 'report' tools will first present the user with a menu to choose the event to browse. After that the user can either press <- to go back to the menu and choose another event or instead press TAB to go the next event without having to go back to the menu or shift-TAB (UNTAB) to go the previous event, useful to quickly visually see if multiple events are correlated. The handling of each hists browser return was broken by the ed7e566, that combined both switches, the first that was for choosing the event and the second that was for checking if switching to the next event without passing thru the events menu. Repeat with me: Don't be clever like that. Fix it by moving the switch to right after the call to the hists browser, making abundantly clear that the two switches are unrelated. This also fixes a compiler warning about the 'pos' variable being possibly used unitialized.

2011-10-11perf hists browser: Recalculate browser pointers after resort/decayArnaldo Carvalho de Melo3-7/+26
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.

2011-10-07perf top: Reuse the 'report' hist_entry/hists classesArnaldo Carvalho de Melo1-236/+0
This actually fixes several problems we had in the old 'perf top': 1. Unresolved symbols not show, limitation that came from the old "KernelTop" codebase, to solve it we would need to do changes that would make sym_entry have most of the hist_entry fields. 2. It was using the number of samples, not the sum of sample->period.

This allows passing a timer to be run periodically, which will update the hists tree that then gers refreshed on the screen, just like the Live mode (symbol entries, annotation) we already have in 'perf top --tui'.

2011-04-15perf hists browser: Fix seg fault when annotate null symbolLin Ming2-3/+5
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.

2011-03-06perf tools: Improve support for sessions with multiple eventsArnaldo Carvalho de Melo1-14/+18
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.

2011-02-25perf ui browser: Introduce ui_browser__show_titleArnaldo Carvalho de Melo2-4/+17
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.

This is not a problem when we're not at the bottom of the active symbols list, so was not noticed, but at the end of the screen it falls apart.

Now one has just to press the right key, 'a' or Enter on the main 'perf top --tui' screen to live annotate the symbol under the cursor. The annotate window starts centered on the hottest line (the one with most samples so far) then TAB and shift+TAB can be used to go to the prev/next hot line. Pressing 'H' at any point will center again the screen on the hottest line.
