perf ui/tui: Print backtrace symbols when segfault occurs

2014-12-23T15:05:59+00:00

The output will look like below.  (I added an error into ui__init() for
the test).

  $ perf report

perf ui: Rename ui_progress to ui_progress_ops

2013-10-23T17:41:23+00:00

Reserving 'struct ui_progress' to the per progress instances, not to the
particular set of operations used to implmenet a progress bar in the
current UI (GTK, TUI, etc).

perf tools: Remove dependency on libnewt

2013-04-01T15:23:21+00:00

Now that the map browser shares the input routine with the hists
browser, there is no need for using any libnewt routine, so remove all
traces except for honouring NO_NEWT=1 on the makefile command line as an
indication that TUI support is not needed, in fact it just sets
NO_SLANG=1.

perf ui: Introduce generic ui_progress helper

2012-11-14T19:52:39+00:00

Make ui_progress functions generic so that UI frontend code will add its
callbacks.

perf tools: Use __maybe_used for unused variables

2012-09-11T15:19:15+00:00

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.

perf hists browser: Use perf_hpp__format functions

2012-09-08T16:20:13+00:00

Override hpp->color functions for TUI. Because line coloring is done
outside of the function, it just sets the percent value and pass it.

perf ui gtk: Add perf_gtk__show_helpline() for pr_*

2012-08-17T15:37:56+00:00

Use helpline for printing error/debug messages. The code resembles a TUI
counter part and only print the first line of the message.

perf ui: Introduce struct perf_error_ops

2012-06-19T16:06:18+00:00

The struct perf_error_ops is for flexible error logging.

We can register appropriate functions based on front-end.

perf ui: Change fallback policy of setup_browser()

2012-05-02T19:17:37+00:00

If gtk2 support is not enabled (or failed for some reason) try TUI again
instead of falling directly back to the stdio interface.

perf ui: Add gtk2 support into setup_browser()

2012-05-02T19:17:34+00:00

Now setup_browser can handle gtk2 front-end so split the TUI code to
ui/tui/setup.c in order to remove dependency.

To this end, make ui__init/exit global symbols and take an argument.
Also split gtk code to ui/gtk/setup.c.
