| * cutils: add a way to disable tracing for a processJamie Gennis2013-04-151-1/+7
| | | | | | | | | | | | | | | | | | This change adds the atrace_set_tracing_enabled call to libcutils. The call can be used to disable all tracing (of the atrace variety) for the current process. This is to be used to disable tracing in the Zygote process, as there is no way for Zygote to be notified of changes to the enabled trace tags. Change-Id: I0b691cc0dcfc65b16e3d17e1db2866a4deb253a7

* libcutils: add support for app tracingJamie Gennis2013-03-281-1/+11
| | | | | | | | | | | This change adds support for tracing using the ATRACE_TAG_APP tag. This tag is enabled only for processes in which the /proc/<pid>/cmdline value appears in the comma-separated list of such values in the debug.atrace.app_cmdlines system property. It is also only enabled if either the ro.debuggable system property is set to 1 or the application has declared itself debuggable in its manifest, which gets reported to libcutils by the framework.

|\ | | | | | | | | | | | | atomic operations." * commit '7f692fe6448049dca2795d7d648615a2dc7a500c': Fail-proof the inline directives for SMP atomic operations.
| * Fail-proof the inline directives for SMP atomic operations.Ben Cheng2012-12-073-88/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The various atomic operations are declared as inline in the header files to cut the function call overhead. However, the plain inline keyword is just a suggestion to the compiler which makes its own decision on whether to inline them or not. Worst, if they are not inlined, the -fvisibility-inlines-hidden compiler flag will render them as hidden symbols in the object file. If they are picked up by the linker over the ones supplied in libcutils.so the following warning will be reported: warning: hidden symbol 'android_atomic_inc' in foo.o is referenced by DSO bar.so One way is to add __attribute__((visibility("default"))) to those inline functions to suppress the linker warnings. A better way is to force inlining as with this patch. Change-Id: Ie4fcfdfaaf06f42d351619a0d89671a9df15ca2f
* | cutils: trace: use ANDROID_SMP to switch atomicsAlex Ray2012-11-301-1/+6
| | | | | | | | | | | | | | | | | | With inline atomics, trace functions have no non-inline function calls in the fast (tracing off) path. To enable this, ANDROID_SMP must be defined for the project. Otherwise, normal (non-inline) atomics are used. Change-Id: Id1f75bdf7db2f5d319a389ad411f55073d78c48c

* | Enhance native stack dumps.Jeff Brown2012-06-081-0/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provides a new mechanism for dumpstate (while running as root) to request that debuggerd dump the stacks of native processes that we care about in bug reports. In this mode, the backtrace is formatted to look similar to a Dalvik backtrace. Moved the tombstone generating code into a separate file to make it easier to maintain. Fixed a bug where sometimes the stack traces would be incomplete because we were not waiting for each thread to stop after issuing PTRACE_ATTACH, only the main thread. So sometimes we were missing traces for some threads. Refactored the logging code to prevent accidentally writing data to logcat when explicitly dumping a tombstone or backtrace from the console. Only root or system server can request to dump backtraces but only root can dump tombstones. Bug: 6615693 Change-Id: Ib3edcc16f9f3a687e414e3f2d250d9500566123b
