2011-10-27perf hists: Fix recalculation of total_period when sorting entriesArnaldo Carvalho de Melo
We were doing parts of it in hists__collapse_resort and parts of it in hists__output_resort, leading to a bogus total_period. Fix it by doing just the filtering operation when collapsing because there we know that the Zoom operations adds filters just what is in hists->entries, not to the new batch of entries being collapsed. And move all the nr_entries + total_period recalculation to hists__output_resort since we will traverse all entries anyway there. Problem introduced when developing threaded addition of new batches of hist_entries, i.e. post v3.1.

2011-10-26perf evlist: Fix grouping of multiple eventsArnaldo Carvalho de Melo
The __perf_evsel__open routing was grouping just the threads for that specific events per cpu when we want to group all threads in all events to the first fd opened on that cpu. So pass the xyarray with the first event, where the other events will be able to get that first per cpu fd. At some point top and record will switch to using perf_evlist__open that takes care of this detail and probably will also handle the fallback from hw to soft counters, etc. Reported-by: Deng-Cheng Zhu <dczhu@mips.com> Tested-by: Deng-Cheng Zhu <dczhu@mips.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/n/tip-ebm34rh098i9y9v4cytfdp0x@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2011-10-20perf tools: Fix tracing info recordingJiri Olsa
Fixing the way the tracing information is stored within record command. The current implementation is causing issues for pipe output. Following commands fail currently: perf script syscall-counts ls perf record -e syscalls:sys_exit_read ls | ./perf report -i - The tracing information is part of the perf data file. It contains several files from within the tracing debugfs and procs directories. Beside some static header files, for each tracing event the format file is added. The /proc/kallsyms file is also added. The tracing data are stored with preceeding size. This is causing some dificulties for pipe output, since there's no way to tell debugfs/proc file size before reading it. So, for pipe output, all the debugfs files were read twice. Once to get the overall size and once to store the content itself. This can cause problem in case any of these file changed, within the storage time. To fix this behaviour and ensure the integrity of the tracing data, we: - read debugfs/proc file into the temp file - get temp file size and dump it to the pipe - dump the temp file contents to the pipe Cc: Eric Dumazet <eric.dumazet@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Neil Horman <nhorman@tuxdriver.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Steven Rostedt <rostedt@goodmis.org> Link: http://lkml.kernel.org/r/20111020135943.GD2092@jolsa.brq.redhat.com Signed-off-by: Jiri Olsa <jolsa@redhat.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Following the 'perf report' model we don't zap hist_entry instances from the rb tree, we just keep them with he->filtered set to a mask of the filters applied to it (thread, parent, DSO so far).

2011-10-19perf tools: handle endianness of feature bitmapDavid Ahern
Feature bitmap is declared as an array of unsigned longs -- not good since its size can differ between the host that generated the data file and the host analyzing the file. We need to handle endianness, but we don't know the size of the unsigned long where the file was generated. Take a best guess at determining it: try 64-bit swap first (ie., file created on a 64-bit host), and check if the hostname feature bit is set (this feature bit is forced on as of fbe96f2). If the bit is not, undo the 64-bit swap and try a 32-bit swap. If the hostname bit is still not set (e.g., older data file), punt and fallback to the original behavior -- clearing all feature bits and setting buildid.

2011-10-14perf buildid: Fix possible unterminated readlink() result bufferThomas Jarosch
The readlink function doesn't guarantee that a '\0' will be put at the end of the provided buffer if there is no space left. No need to do "buf[len] = '\0';" since the buffer is allocated with zalloc().

2011-10-14perf ui browser: Add filter methodArnaldo Carvalho de Melo
Its becoming common to allow the user to filter out parts of the data structure being browsed, like already done in the hists browser and in the annotate browser in the next commit, so provide it directly in the ui_browser class list_head helpers. More work required to move the equivalent routines found now in the hists browser to the rb_tree helpers.

2011-10-14perf hists browser: Invalidate ui_browser->top after timer callsArnaldo Carvalho de Melo
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 Melo
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.

We were removing only when using a --sort order that needs collapsing, while we also use it in the threaded case, causing memory corruption because we were scribbling freed hist entries, oops.

To do that we needed to stop using newtForm, as we don't want libnewt to catch the xterm resize signal. Remove some more newt calls and instead use the underlying libslang directly. In time tools/perf will use just libslang.
