Ying Wang c796ed9746 We need libcutils to include liblog
For some prebuilts were built against libcutils with liblog in it.
Unfortunately that means in the future if someone checks in prebuilts
that are built against libcutils and they don't explicitly link against
liblog, they will again prevent us from removing liblog from libcutils.

Jamie Gennis 774f929991 libcutils: add support for app tracing
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.

Ben Cheng 26f447f5da am 7f692fe6: am 523e21d3: Merge "Fail-proof the inline directives for SMP atomic operations."
* commit '7f692fe6448049dca2795d7d648615a2dc7a500c':
  Fail-proof the inline directives for SMP atomic operations.
2012-12-07 14:37:04 -08:00
Ben Cheng 5206d59712 Fail-proof the inline directives for SMP atomic operations.
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.

Jeff Brown 053b865412 Enhance native stack dumps.
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.
