Kate Stone b9c1b51e45 *** This commit represents a complete reformatting of the LLDB source code
*** to conform to clang-format’s LLVM style.  This kind of mass change has
*** two obvious implications:

Firstly, merging this particular commit into a downstream fork may be a huge
effort.  Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit.  The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):

    find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
    find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;

The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit.  There are alternatives available that will attempt
to look through this change and find the appropriate prior commit.  YMMV.

Saleem Abdulrasool 2d6a9ec935 Clean up vestigial remnants of locking primitives
This finally removes the use of the Mutex and Condition classes. This is an
intricate patch as the Mutex and Condition classes were tied together.
Furthermore, many places had slightly differing uses of time values. Convert
timeout values to relative everywhere to permit the use of
std::chrono::duration, which is required for the use of
std::condition_variable's timeout. Adjust all Condition and related Mutex
classes over to std::{,recursive_}mutex and std::condition_variable.

This change primarily comes at the cost of breaking the TracingMutex which was
based around the Mutex class. It would be possible to write a wrapper to
provide similar functionality, but that is beyond the scope of this change.

Saleem Abdulrasool 16ff860469 remove use of Mutex in favour of std::{,recursive_}mutex
This is a pretty straightforward first pass over removing a number of uses of
Mutex in favor of std::mutex or std::recursive_mutex. The problem is that there
are interfaces which take Mutex::Locker & to lock internal locks. This patch
cleans up most of the easy cases. The only non-trivial change is in
CommandObjectTarget.cpp where a Mutex::Locker was split into two.

Pavel Labath ef984e7dc0 Revert "Add a read_full_buffer argument to ConnectionFileDescriptor::Read"
This reverts commit r268380 as it breaks windows build (I forgot to make neccesary adjustments to

Pavel Labath 240760207e Add a read_full_buffer argument to ConnectionFileDescriptor::Read
Summary:
AdbClient was attempting to handle the case where the socket input arrived in pieces, but it was
failing to handle the case where the connection was closed before that happened. In this case, it
would just spin in an infinite loop calling Connection::Read. (This was also the cause of the
spurious timeouts on the darwin->android buildbot. The exact cause of the premature EOF remains
to be investigated, but is likely a server bug.)

Since this wait-for-a-certain-number-of-bytes seems like a useful functionality to have, I am
moving it (with the infinite loop fixed) to the Connection class, and adding an
appropriate test for it.

Greg Clayton 5df78fa35b Did some cleanup to stop us from leaking Pipe file descriptors.
The main issue was the Communication::Disconnect() was calling its Connection::Disconnect() but this wouldn't release the pipes that the ConnectionFileDescriptor was using. We also have someone that is holding a strong reference to the Process so that when you re-run, target replaces its m_process_sp, but it doesn't get destructed because someone has a strong reference to it. I need to track that down. But, even if we have a strong reference to the a process that is outstanding, we need to call Process::Finalize() to have it release as much of its resources as possible to avoid memory bloat. 

Removed the ProcessGDBRemote::SetExitStatus() override and replaced it with ProcessGDBRemote::DidExit().

Now we aren't leaking file descriptors and the stand alone test suite should run much better.

Vince Harron b9bd6af2f2 ConnectionFileDescriptor::BytesAvailable reading too many command bytes
ConnectionFileDescriptor::BytesAvailable was reading multiple command
bytes from the command pipe but only processing the first. This
change only allows one byte to be read at a time, ensuring that all
get handled.

This isn't known to cause any bugs, but it might cause current/future
bugs.

Summary:
ConnectionFileDescriptor::Read was returning eConnectionStatusError instead of 0

were read.

Robert Flack a0e70cd4b6 Allow multiple simultaneous connections to platform.
Adds the --server argument to lldb-server platform which when specified will allow multiple simultaneous connections by forking off to handle each individual connection. This will allow us to run the remote tests in parallel.

Test Plan:
Run: lldb-server platform --listen *:1234 --server
Connect from multiple lldb clients simultaneously.
I will also test running the test suite remotely with multiple simultaneous jobs.

This function returns a URI of the resource that the connection is connected to. This is especially important for connections established by accepting a connection from a remote host.

Also fixed up some documentation in Connection::Write

Zachary Turner 0b9d3eefdb Enhance the Pipe interface for better portability.
This patch makes a number of improvements to the Pipe interface.

1) An interface (PipeBase) is provided which exposes pure virtual
   methods for any implementation of Pipe to override.  While not
   strictly necessary, this helps catch errors where the interfaces
   are out of sync.

2) All methods return lldb_private::Error instead of returning bool
   or void.  This allows richer error information to be propagated
   up to LLDB.

3) A new ReadWithTimeout() method is exposed in the base class and
   implemented on Windows.

4) Support for both named and anonymous pipes is exposed through the
   base interface and implemented on Windows.  For creating a new
   pipe, both named and anonymous pipes are supported, and for
   opening an existing pipe, only named pipes are supported.

New methods described in points #3 and #4 are stubbed out on posix,
but fully implemented on Windows.  These should be implemented by
someone on the linux / mac / bsd side.
