Version liblog LL-NDK library

2019-04-02T19:22:50+00:00

The system version of liblog has been versioned.  Do the same for
LL-NDK verison as well.

Test: Build and examine the dynamic symbols.

liblog: don't return 0xFFFFFFFF as an invalid log id.

2019-03-25T23:41:39+00:00

There are a bunch of branches that check "id >= LOG_ID_MAX", but because
C++ hates you, this does a promotion to signed int despite the
fact that both sides of the comparison are the same enum with an
underlying type of unsigned int. (C++17 §7.6.3)

Return LOG_ID_MAX instead of a value that gets promoted to signed -1, to
avoid this.

__android_log_is_debuggable() shouldn't be an apex symbol

2019-02-20T20:52:02+00:00

Remove a superfluous check in fs_mgr, since those return values are
already impossible for a non-debuggable build.  Replace a one time
call to __android_log_is_debuggable(), since there's no reason to
cache the value or use this symbol.

Merge "liblog: make liblog_headers truly stand-alone."

liblog: make liblog_headers truly stand-alone.

2019-02-13T20:42:06+00:00

We don't want to imply dependencies on libc or libc++.

liblog: simplify socket_local_client() and always use CLOEXEC

2019-02-12T20:53:19+00:00

socket_local_client() was copied from libcutils, but we only need a
small subset of its functionality.  We instead create our own version
with just the needed parts.

Importantly, use CLOEXEC in this new function and other places where
it was missing previously.
