Issue D5632 fixed an issue where linux would dump spurious output to tty on startup (due to a broadcast stop event). After the checkin, it was noticed on FreeBSD a unit test was now failing. On closer investigation I found the test was using the C++ API to launch an inferior while using an SBListener to monitor the public state changes. As on OSx, it was expecting to see:
eStateRunning
eStateStopped
On Linux/FreeBSD, there is an extra state change
eStateLaunching
eStateRunning
eStateStopped
I reworked the test to work for both cases and re-enabled the test of FreeBSD.

The default value for opt.thread_count was multiprocessing.cpu_count(),
which meant the LLDB_TEST_THREADS environment variable was never used.
It's not easy to pass the -t option to the test run when invoking it
from e.g. 'ninja check-lldb', so having the environment variable as an
option is useful.
Change the logic so that the thread count is set by the first one of:
1. The -t option to test/dosep.py
2. The LLDB_TEST_THREADS environment variable
3. The machine's CPU count from multiprocessing.cpu_count()

The problem is that editline currently is trying to be smart when we paste things into a terminal window. It detects that input is pending and multi-line input is accepted as long as there is anything pending.
So if you open lldb and paste the text between the quotes:
"command regex carp
s/^$/help/
carp
"
We still still be stuck in the "command regex" multi-line input reader as it will have all three lines:
"s/^$/help/
carp
"
The true fix for this is something Kate Stone will soon work on:
- multi-line input readers must opt into this paste/pending input feature ("expr" will opt into it, all other commands won't)
- If we are in a multi-line input reader that requests this and stuff is pasted, then it will do what it does today
- if we start in a IOHandler that doesn't need/want pending input and text is pasted, and we transistion to a IOHandler that does want this functionality, then disable the pending input. Example text would be:
"frame variable
thread backtrace
expr
for (int i=0;i<10;++i)
(int)printf("i = %i\n", i);
frame select 0
"
When we push the expression multi-line reader we would disable the pending input because we had pending input _before_ we entered "expr".
If we did this first:
(lldb) expr
Then we pasted:
"void foo()
{
}
void bar()
{
}
"
Then we would allow the pending input to not look for an empty line to terminate the expression. We filed radar 19008425 to track fixing this issue.

Fixes include:
- Add a new lldbtest.TestBase function named registerSharedLibrariesWithTarget. This function can be called using the shared libraries for your test suite either as shared library basename ("foo"), path basename ("libfoo.dylib") or full path ("/tmp/lldb/test/lang/c/carp/libfoo.dylib"). These shared libraries are then registered with the target so they will be downloaded when the test is run remotely.
- Changed a lot of tests over to use SBDebugger::CreateTarget(...) calls instead of using "file a.out" commands.
- Cleaned up some tests to add new locations for breakpoints that all compilers should be able to abide by. Some tests and constants being loaded into values of structs and some compilers like arm64 will often combine two constant data loads into a single source line so some breakpoint locations were not being set correctly. Adding lines like 'puts("")' allow us to lock onto a source line that will have code.

The problem was that SBTarget::ReadMemory() was making a new section offset lldb_private::Address by doing:
size_t
SBTarget::ReadMemory (const SBAddress addr,
void *buf,
size_t size,
lldb::SBError &error)
{
...
lldb_private::Address addr_priv(addr.GetFileAddress(), NULL);
bytes_read = target_sp->ReadMemory(addr_priv, false, buf, size, err_priv);
This is wrong. If you get the file addresss from the "addr" argument and try to read memory using that, it will think the file address is a load address and it will try to resolve it accordingly. This will work fine if your executable is loaded at the same address (no slide), but it won't work if there is a slide.
The fix is to just pass along the "addr.ref()" instead of making a new addr_priv as this will pass along the lldb_private::Address that is inside the SBAddress (which is what we want), and not always change it into something that becomes a load address (if we are running), or abmigious file address (think address zero when you have 150 shared libraries that have sections that start at zero, which one would you pick). The main reason for passing a section offset address to SBTarget::ReadMemory() is so you _can_ read from the actual section + offset that is specified in the SBAddress.

All of these test fixups are prep work for when llgs is
running with llgs for local process debugging, where these
tests fail without the ptracer lock-down suppression.
llvm-svn: 220656
Similar to previous fix, this augments the test inferior to
immediately indicate it may be ptraced by any Linux process
when the appropriate symbols are defined.
This seems to indicate we need to fix our lldb attach logic to
catch when an attach fails, and trigger an appropriate error
instead of the current behavior of hanging indefinitely.
llvm-svn: 220654
Similar to a recent test I fixed for gdb-remote attach scenarios, this
fix is for Linux kernels, such as Ubuntu's stock setup on 11.04-ish and
later, where ptrace starts requiring a ptracer to be an ancestor of the
inferior to be ptraced. This change checks for Linux and the ptrace-related
flags. If they're found, it tries to switch on the "allow any ptracer" mode
for the inferior as the first statements in the program. It's a best-effort
solution - if the prctl call fails, the failure is ignored, and probably will
lead to the test failing.
The ptrace security behavior can be modified system-wide, but is outside the
scope of the test to address. Hence I went with this particular solution.

BreakpointLocation::ShouldStop. That worked but wasn't really right,
since there's nothing to guarantee that won't get called more than

Also fix a test case that was assuming if you had many threads running some

There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them.

This fix addresses a requirement on some Linux kernels that limits
a PTRACER to be an ancestor of the ptraced process. The fix in this
case is to have the inferior test exe explicitly allow any ptracer
to attach.
This fixes several ptrace-related issues that I did not see on a modified
kernel we used internally on my team.

of the boilerplate that is required for test

Inline testcases have much simplified python files

This patch gives LLDB some ability to interact with AddressSanitizer runtime library, on top of what we already have (historical memory stack traces provided by ASan). Namely, that's the ability to stop on an error caught by ASan, and access the report information that are associated with it. The report information is also exposed into SB API.
More precisely this patch...
adds a new plugin type, InstrumentationRuntime, which should serve as a generic superclass for other instrumentation runtime libraries, these plugins get notified when modules are loaded, so they get a chance to "activate" when a specific dynamic library is loaded
an instance of this plugin type, AddressSanitizerRuntime, which activates itself when it sees the ASan dynamic library or founds ASan statically linked in the executable
adds a collection of these plugins into the Process class
AddressSanitizerRuntime sets an internal breakpoint on __asan::AsanDie(), and when this breakpoint gets hit, it retrieves the report information from ASan
this breakpoint is then exposed as a new StopReason, eStopReasonInstrumentation, with a new StopInfo subclass, InstrumentationRuntimeStopInfo
the StopInfo superclass is extended with a m_extended_info field (it's a StructuredData::ObjectSP), that can hold arbitrary JSON-like data, which is the way the new plugin provides the report data
the "thread info" command now accepts a "-s" flag that prints out the JSON data of a stop reason (same way the "-j" flag works now)
SBThread has a new API, GetStopReasonExtendedInfoAsJSON, which dumps the JSON string into a SBStream
adds a test case for all of this
I plan to also get rid of the original ASan plugin (memory history stack traces) and use an instance of AddressSanitizerRuntime for that purpose.

The two backticks in the lldb style formatter triggers the sub-expression evaluation in

The way to do this is to write a synthetic child provider for your type, and have it vend the (optional) get_value function.
If get_value is defined, and it returns a valid SBValue, that SBValue's value (as in lldb_private::Value) will be used as the synthetic ValueObject's Value
The rationale for doing things this way is twofold:
- there are many possible ways to define a "value" (SBData, a Python number, ...) but SBValue seems general enough as a thing that stores a "value", so we just trade values that way and that keeps our currency trivial
- we could introduce a new level of layering (ValueObjectSyntheticValue), a new kind of formatter (synthetic value producer), but that would complicate the model (can I have a dynamic with no synthetic children but synthetic value? synthetic value with synthetic children but no dynamic?), and I really couldn't see much benefit to be reaped from this added complexity in the matrix
On the other hand, just defining a synthetic child provider with a get_value but returning no actual children is easy enough that it's not a significant road-block to adoption of this feature

This change does the following:
* Remove test/c++/...

* Add an initial Plugins/Process?linux/ThreadStateCoordinatorTest.cpp.
- currently failing a test (intentional).
- added a bare-bones ThreadStateCoordinator.cpp to Plugins/Process/Linux,
more soon. Just enough to prove out running gtest on Ubuntu and MacOSX.
* Added recursive make machinery so that doing a 'make' in gtest/ is
sufficient to kick off the existing test several directories down.
- Caveat - I currently short circuit from gtest/unittest/Makefile directly to
the one and only gtest/unittest/Plugins/Process/Linux directory. We'll need
to add the intervening layers. I haven't done this yet since to fix the
Xcode test failure correspondence, I may need to add a python layer which
might just handle the directory crawling.
* Added an Xcode project to the lldb workspace for gtest.
- Runs the recursive make system in gtest/Makefile.
- Default target is 'test'. test and clean are supported.
- Currently does not support test failure file/line correspondence.
Requires a bit of text transformation to hook that up.

Runs with default Makefile target "test" using gmake within a given

The Makefile.rules currently assume it is using the LLVM gtest. It works on
a canonical MacOSX dir structture (i.e. lldb, lldb/llvm, lldb/llvm/tools/clang).
It also works on Ubuntu assuming the standard dir layout of llvm, llvm/tools/clang,
llvm/tools/lldb. In this case, it expects a directory called build-debug parallel
to the llvm source dir. All directory assumptions can be overridden with
environment variables. See test/c++/make/Makefile.rules for details.
We'll want to make this smarter in the future, particularly around finding the LLVM build
output dir.

For the Objective-C case, we do not have a "function type" notion, so we actually end up wrapping the clang ObjCMethodDecl in the Impl object, and ask function-y questions of it

since only the 32-bit MSVCRT was in the path.
This patch addresses this by figuring out, at CMake time, whether
or not you are building LLDB with a 64 or 32-bit toolchain. Then,
it explicitly passes this value to the test runner, causing the
test runner to build tests whose architecture matches that of LLDB
itself. This can still be overridden by setting the CMake variable
LLDB_TEST_EXECUTABLE_ARCH=(x64|x86)

This was causing core dumps on MacOSX and was not properly
cleaning up the state of the inferior before exiting.
The test was overriding def tearDown(), but failed to
call the base class after doing its own cleanup. This
essentially eliminated normal clean-up activity.

Currently, the test runner makes the assumption that it will run
commands through /bin/sh. This is obviously not true on Windows,
so this patch abstracts this logic out somewhat. Instead of
having the caller build the command string himself, the caller
will now pass in argument list of the form [[a, b], [c, d], ...]
which will get converted into a string of the form a b; c d or
a b && c d, depending on the platform.

lldb -P, which outputs its python path, works by using Host-layer
facilities to get information about the loaded python module. This
Host functionality was unimplemented on Windows, so this patch
implements it. Additionally, it removes a pexpect dependency from
the test runner and uses an equivalent invocation of subprocess.

99% of this CL is simply moving calls to "import pexpect" to a more
narrow scope - i.e. the function that actually runs a particular
test. This way the test suite can run on Windows, which doesn't have
pexpect, and the individual tests that use pexpect can be disabled on
a platform-specific basis.
Additionally, this CL fixes a few other cases of non-portability.
Notably, using "ps" to get the command line, and os.uname() to
determine the architecture don't work on Windows. Finally, this
also adds a stubbed out builder_win32 module.
The full test suite runs correctly on Windows after this CL, although
there is still some work remaining on the C++ side to fix one-shot
script commands from LLDB (e.g. script print "foo"), which currently
deadlock.

This fixes all of the hidden ivar test cases and any case where we try to find the full definition of an objective C class.
This also means hidden ivars show up again.

This change adds a member to the base test case for gdb-remote that
indicates whether a stub makes two X stop notification reports on kill
commands. This is set to true for debugserver tests.
The test for killing an attached process after it's first stop notification
has been modified to look at that flag and add an extra X packet matcher
so the "unmatched packet warning" doesn't get emitted for the second X on
MacOSX with debugserver.
I also broke those tests out of the monolithic TestLldbGdbServer mega test
case and put it in its own, new TestGdbRemoteKill.py file and test case.
Tested:
Ubuntu 14.04 x86_64, clang-3.5 built lldb, no test failures.
MacOSX 10.9.4, Xcode 6.0 Beta 3 built lldb, no test failures.

Fixed the test case to use a runtime function prototype that will be correct ([NSString stringWithCString: "new"]) instead of one that won't (expression str = [NSString stringWithFormat: @"%cew", 'N']). The runtime doesn't track vararg functions correctly so we can't reconstitute the function correctly.
Also fixed some expressions that used "str_id" whose type was "id" and do the necessary casting since "id" doesn't have any methods.

Now that llgs supports communicating the 0-port choose-a-port
mechanism and can communicate that back to a caller via the
--named-pipe option (at parity with debugserver), we use this
mechanism to always start llgs and debugserver gdb-remote
protocol tests without needing to use some port arbitration
mechanism. This eliminates some potential intermittent failures vs. the
previous random port and collision-avoidance strategy used.

The --setsid (-S) option changes the session id for the lldb-gdbserver process.
This is used by tools such as lldb-platform and allows the user to prevent
llgs from being in the same session as a calling terminal session.
This will prevents terminal group control signals from affecting
lldb-gdbserver.

TestCallStopAndContinue.py (Linux, MacOSX)
TestCallWithTimeout.py (Linux)
TestConvenienceVariables.py (Linux)

The following new tests have been marked XFAIL but are just
intermittently failing:
TestMultipleDebug.py (definitely intermittent on MacOSX, not sure I've seen
it pass yet on Linux)

debug sessions simultaneously to expose race conditoin/locking
issues.
This directory has an inferior program, testprog.cpp that has a
couple of functions we can put breakpoints on.
It has a driver program, multi-process-driver.cpp, which links
against the LLDB solib and uses the SB APIs. It creates 50 pthreads,
creates a debugger on all of them, launches a debug session of the
inferior testprog, hits a couple breakpoints, walks the stack,
continues, etc., and then kills the inferior and ends the debug
session.
A pass is if all fifty debug sessions complete successfully
in the alloted time (~60 seconds).
We may need to tweak this one to work correctly on different
platforms/targets but I wanted to get it checked in to start.

Fixed up gdb-remote port-grabbing code to use a random port in a wide range,
and to allow that to fail more gracefully. This appears to have solved some
gdb-remote intermittent failing behavior.
