perf evsel: Introduce perf_evsel__open_strerror method

2013-01-24T19:40:09+00:00

That consolidates the error messages in 'record', 'stat' and 'top', that
now get a consistent set of messages and allow other tools to use the
new method to report problems using whatever UI toolkit.

perf ui: Always compile error printing code

2012-12-09T11:46:04+00:00

It is used everywhere so always build it regardless of ui engine.

perf ui: Add ui_progress__finish()

2012-11-14T19:52:56+00:00

Sometimes we need to know when the progress bar should disappear.

Checking curr >= total wasn't enough since there're cases not met that
condition for the last call.

So add a new ->finish callback to identify this explicitly.  Currently
only GTK frontend needs it.

perf tools: Convert to GTK2_SUPPORT

2012-10-02T21:36:23+00:00

For building perf without gtk+2, we can set NO_GTK2=1 as a argument of
make.  It then defines NO_GTK2_SUPPORT macro for C code to do the
proper handling.  However it usually used in a negative semantics -
e.g. #ifndef - so we saw double negations which can be misleading.
Convert it to a positive form to make it more readable.

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 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 tools: Move UI bits to tools/perf/ui directory

2012-04-11T20:16:40+00:00

Move those files to new directory in order to be prepared to further UI
work. Makefile and header file pathes are adjusted accordingly.

perf ui browser: Handle K_RESIZE in dialog windows

2011-10-26T15:15:07+00:00

Just provide wrappers for things like ui__warning, ui__dialog_yesno and
if they return K_RESIZE, refresh dimensions, redraw the entries, etc.
