Colin Cross 9993e799f1 Hide warning in cutils/trace.h
system/core/include is included in the global include path using
-isystem, which hides all warnings.  cutils/trace.h has an ignored
return value warning, move the implementation to trace-dev.c so it
doesn't cause warnings in every module that includes it in preparation
for moving from -isystem to -I.

Test: m -j native

Hans Boehm 54828dc739 Fix SharedBuffer. Remove aref.
Add comment that SharedBuffer is deprecated.

Both aref and SharedBuffer had memory ordering bugs.  Aref has no
clients.

SharedBuffer had several bugs, which are fixed here:

mRefs was declared neither volatile, not atomic, allowing the
compiler to, for example, reuse a stale previously loaded value.

It used the default android_atomic release memory ordering, which
is insufficient for reference count decrements.

It used an ordinary memory read in onlyOwner() to check whether
an object is safe to deallocate, without any attempt to ensure
memory ordering.

Comments claimed that SharedBuffer was exactly 16 bytes, but
this was neither checked, nor correct on 64-bit platforms.

This turns mRef into a std::atomic and removes the android_atomic
dependency.

David Pursell 8385fb299f libcutils: add multi-buffer socket send.
Unix and Windows both have functions to write multiple buffers to a
socket with a single call but they have very different signatures. This
CL creates some cross-platform functions to be able to perform these
operations in a uniform way, which will be required for upcoming
fastboot functionality.

This CL also fixes some inconsistent spacing in the touched files.

David Pursell 756e1c81e8 libcutils: add socket_get_local_port().
Tests that require a local server currently hardcode a test value,
which can run into conflicts depending on what's currently running on
the machine.

This CL adds socket_get_local_port(), which lets us pass 0 so the
system picks an open port and we can query which port it chose.

2016-01-22 18:46:54 +00:00
David Pursell 572bce2908 fastboot: use cutils socket functions.
Now that cutils has cross-platform socket functionality, we can
restructure fastboot to remove platform-dependent networking code.

This CL adds socket_set_receive_timeout() to libcutils and combines the
fastboot socket code into a single implementation. It also adds TCP
functionality to fastboot sockets, but nothing uses it yet except for
the unit tests. A future CL will add the TCP protocol which will use
this TCP socket implementation.

David Pursell 0eb8e1b706 libcutils: share Windows networking code.
This CL moves Windows networking code from fastboot to libcutils so
that it can be shared with other host programs such as adb.

Not all libcutils networking functions have been implemented for
Windows, just those necessary for fastboot. In the next CL I will do
the same for adb, adding any additional required functions.

Unit tests have also been added to test the functions using a loopback
connection.

ATRACE_TAG_NOT_READY: use an unsigned constant when shifting bits.
Otherwise, the value overflows on shift. The users of this constant

  Use fsck.f2fs -a instead of -f for faster boot
2015-07-21 18:25:57 +00:00
Yusuke Sato 0df08271fb Use fsck.f2fs -a instead of -f for faster boot
and run fsck with -f on clean shutdown instead.

With -f, fsck.f2fs always performs a full scan of the /data
partition regardless of whether the partition is clean or not.
The full scan takes more than 2 seconds on volantis-userdebug
and delays the OS boot.

With -a, the command does almost nothing when the partition
is clean and finishes within 20-30ms on volantis-userdebug.
When the partition has an error or its check point has
CP_FSCK_FLAG (aka "need_fsck"), the command does exactly the
same full scan as -f to fix it.
