perf tools: Introduce zfree

2013-12-27T18:17:00+00:00

For the frequent idiom of: free(ptr); ptr = NULL; Make it expect a pointer to the pointer being freed, so that it becomes clear at first sight that the variable being freed is being modified.

perf ui browser: Remove misplaced __maybe_unused

2013-12-19T19:25:17+00:00

The 'browser' arg _is_ used, so ditch the misplaced attribute.

perf ui browser: Fix segfault caused by off by one handling END key

2013-11-14T19:00:31+00:00

$ perf record ls $ perf report Press 'down enter end' Result: Program received signal SIGSEGV, Segmentation fault. The UI browser, used on a argv array would access past the end of the array on SEEK_END because it wasn't using 'nr_entries - 1', fix it.

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 browsers: Fix usage of __ in struct names

2013-01-24T19:40:51+00:00

In tools/perf we use a convention where __ separates the struct name from the function name for functions that operate on a struct instance. Fix this usage by removing it from the struct names and fix also the associated functions.

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 browser: Stop using 'self'

2012-05-30T01:42:18+00:00

Stop using this python/OOP convention, doesn't really helps. Will do more from time to time till we get it cleaned up in all of /perf.
