Summary:
The comments on this class were out of date with the implementation, and
the implementation itself was inconsistent with our usage of the Timeout
class (I started converting everything to use this class back in D27136,
but I missed this one). I avoid duplicating the waiting logic by
introducing a templated WaitFor function, and make other functions
delegate to that. This function can be also used as a replacement for
the unused WaitForBitToBeSet functions I removed, if it turns out to be
necessary.
As this changes the meaning of a "zero" timeout, I tracked down all the
callers of these functions and updated them accordingly. Propagating the
changes to all the callers of RunShellCommand was a bit too much for
this patch, so I stopped there and will continue that in a follow-up
patch.
I also add some basic unittests for the functions I modified.

This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.
FYI, the script I used was:

import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:

text = ""
comment = re.compile(r'^( *//) ([^ ].*)$')
special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
for line in f:
match = comment.match(line)
if match and not special.match(match.group(2)):
# skip intentionally short comments.
if not text and len(match.group(2)) < 40:
out.write(line)
continue
if text:
text += " " + match.group(2)
else:
header = match.group(1)
text = match.group(2)
continue
if text:
filled = textwrap.wrap(text, width=(78-len(header)),
break_long_words=False)
for l in filled:
out.write(header+" "+l+'\n')
text = ""
out.write(line)
os.rename(tmp, sys.argv[1])

Summary:
It defined a couple of types (condition_t) which we don't use anymore,
as we have c++11 goodies now. I remove these definitions.
Also it unnecessarily included a couple of headers which weren't
necessary for it's operation. I remove these, and place the includes in
the relevant files (usually .cpp, usually in Host code) which use them.
This allows us to reduce namespace pollution in most of the lldb files
which don't need the OS-specific definitions.

Summary:
These interfaces have no dependencies, so it makes sense for them to be
in the lowest level modules, to make sure that other parts of the
codebase can use them without introducing loops.
The only exception here is the Connection::CreateDefaultConnection
method, which I've moved to Host, as it instantiates concrete
implementations, and that's where the implementations live.

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.
A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

This support was landed in r300579, and reverted in r300669 due to failures on the bots.
The failures were caused by sockets not being properly closed, and this updated version of the patches should resolve that.
Summary from the original change:
This patch adds IPv6 support to LLDB/Host's TCP socket implementation. Supporting IPv6 involved a few significant changes to the implementation of the socket layers, and I have performed some significant code cleanup along the way.
This patch changes the Socket constructors for all types of sockets to not create sockets until first use. This is required for IPv6 support because the socket type will vary based on the address you are connecting to. This also has the benefit of removing code that could have errors from the Socket subclass constructors (which seems like a win to me).
The patch also slightly changes the API and behaviors of the Listen/Accept pattern. Previously both Listen and Accept calls took an address specified as a string. Now only listen does. This change was made because the Listen call can result in opening more than one socket. In order to support listening for both IPv4 and IPv6 connections we need to open one AF_INET socket and one AF_INET6 socket. During the listen call we construct a map of file descriptors to addrin structures which represent the allowable incoming connection address. This map removes the need for taking an address into the Accept call.
This does have a change in functionality. Previously you could Listen for connections based on one address, and Accept connections from a different address. This is no longer supported. I could not find anywhere in LLDB where we actually used the APIs in that way. The new API does still support AnyAddr for allowing incoming connections from any address.
The Listen implementation is implemented using kqueue on FreeBSD and Darwin, WSAPoll on Windows and poll(2) everywhere else.

The break the linux bots (and probably any other machine which would
run the test suite in a massively parallel way). The problem is that it
can happen that we only successfully create an IPv6 listening socket
(because the relevant IPv4 port is used by another process) and then the
connecting side attempts to connect to the IPv4 port and fails.
It's not very obvious how to fix this problem, so I am reverting this
until we come up with a solution.

This moves the following classes from Core -> Utility.
ConstString
Error
RegularExpression
Stream
StreamString
The goal here is to get lldbUtility into a state where it has
no dependendencies except on itself and LLVM, so it can be the
starting point at which to start untangling LLDB's dependencies.
These are all low level and very widely used classes, and
previously lldbUtility had dependencies up to lldbCore in order
to use these classes. So moving then down to lldbUtility makes
sense from both the short term and long term perspective in
solving this problem.

This is a large API change that removes the two functions from
StreamString that return a std::string& and a const std::string&,
and instead provide one function which returns a StringRef.
Direct access to the underlying buffer violates the concept of
a "stream" which is intended to provide forward only access,
and makes porting to llvm::raw_ostream more difficult in the
future.

*** 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.

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.

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.

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.

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.

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.
