Todd Fiala 4728cf7e85 surface build error content through test event system
Summary:
print build errors nicely in test output

This test infrastructure change adds a new Python exception
for test subject builds that fail.  The output of the build
command is captured and propagated to both the textual test
output display code and to the test event system.

The ResultsFormatter objects have been modified to do something
more useful with this information.  The xUnit formatter
now replaces the non-informative Python build error stacktrace
with the build error content.  The curses ResultsFormatter
prints a 'B' for build errors rather than 'E'.

The xUnit output, in particular, makes it much easier for
developers to track down test subject build errors that cause
test failures when reports come in from CI.

Todd Fiala 7c5f7caa20 test infra: catch bad decorators and import-time errors
Summary:
This change enhances the LLDB test infrastructure to convert
load-time exceptions in a given Python test module into errors.
Before this change, specifying a non-existent test decorator,
or otherwise having some load-time error in a python test module,
would not get flagged as an error.

With this change, typos and other load-time errors in a python
test file get converted to errors and reported by the
test runner.

This change also includes test infrastructure tests that include
covering the new work here.  I'm going to wait until we have
these infrastructure tests runnable on the main platforms before
I try to work that into all the normal testing workflows.

The test infrastructure tests can be run by using the standard python module testing practice of doing the following:

cd packages/Python/lldbsuite/test_event
python -m unittest discover -s test/src -p 'Test*.py'

Those tests run the dotest inferior with a known broken test and verify that the errors are caught.  These tests did not pass until I modified dotest.py to capture them properly.

@zturner, if you have the chance, if you could try those steps above (the python -m unittest ... line) on Windows, that would be great if we can address any python2/3/Windows bits there.  I don't think there's anything fancy, but I didn't want to hook it into test flow until I know it works there.

I'll be slowly adding more tests that cover some of the other breakage I've occasionally seen that didn't get collected as part of the summarization.  This is the biggest one I'm aware of.

Summary:
The AST contexts are not needed in the server components, and the clang context in particular
pulls in large parts of clang into the binary. Simply removing these two calls reduces the
lldb-server size by about 50%--80%, depending on the architecture and build type.

This should not impact the client parts as the same calls are already present in
SystemInitializerFull.

Greg Clayton 1e20f021f3 Fix some long standing issues that caused tests to be flaky.
The main issues were:
- Listeners recently were converted over to used by getting a shared pointer to a listener. And when they listened to broadcasters they would get a strong reference added to them meaning the listeners would never go away. This caused memory usage to increase and would cause performance issue if many steps were done.
- The lldb_private::Process private state thread had an issue where if a "stop" contol signal was attempted to be sent to that thread, it could end up not responding in 2 seconds and end up getting cancelled which might cause us to cancel a thread that had a mutex locked and it would deadlock the test.

This change makes broadcasters hold onto weak references to listeners. It also fixes some bad threading code that had races inside of it by making the m_events_mutex be non-recursive and getting rid of fragile use of a Predicate<bool> to say that new events are available, and replacing it with using the m_events_mutex with a new m_events_condition to control access to the events in a safer way.

The private state thread now uses a safer way to communicate that the control event has been received by the private state thread: it makes a EventDataReceipt instance that it attaches to the event that sends the control to the private state thread and used this to synchronize the fact that the private state thread has received the event instead of using a Predicate<bool> to convey the info. When the signal event is received, it will pull the event off of the queue in the private state thread and cause the EventData::DoOnRemoval() to be called, which will signal that the event has been received. This cleans up the signal delivery notification so it doesn't rely on a member variable of the process class to convey the info.

std::shared_ptr<EventDataReceipt> event_receipt_sp(new EventDataReceipt());
m_private_state_control_broadcaster.BroadcastEvent(signal, event_receipt_sp);

Pavel Labath 194357c509 Fix a race in ProcessGDBRemote::MonitorDebugServerProcess
Summary:
MonitorDebugServerProcess went to a lot of effort to make sure its asynchronous invocation does
not cause any mischief, but it was still not race-free. Specifically, in a quick stop-restart
sequence (like the one in TestAddressBreakpoints) the copying of the process shared pointer via
target_sp->GetProcessSP() was racing with the resetting of the pointer in DeleteCurrentProcess,
as they were both accessing the same shared_ptr object.

To avoid this, I simply pass in a weak_ptr to the process when the callback is created. Locking
this pointer is race-free as they are two separate object even though they point to the same
process instance. This also removes the need for the complicated tap-dance around retrieving the
process pointer.

Ted Woodward 911d57840a Keep original source path and mapped path in LineEntry
Summary:
The "file" variable in a LineEntry was mapped using target.source-map, except when stepping through inlined code. This patch adds a new variable to LineEntry, "original_file", that contains the original file from the debug info. "file" will continue to (possibly) be mapped.

Some code has been changed to use "original_file". This is code dealing with symbols. Code dealing with source files will still use "file". Reviewers, please confirm that these particular changes are correct.

Tests run on Ubuntu 12.04 show no regression.

Pavel Labath 998bdc5b75 Generalize child process monitoring functions
Summary:
This replaces the C-style "void *" baton of the child process monitoring functions with a more
C++-like API taking a std::function. The motivation for this was that it was very difficult to
handle the ownership of the object passed into the callback function -- each caller ended up
implementing his own way of doing it, some doing it better than others. With the new API, one can
just pass a smart pointer into the callback and all of the lifetime management will be handled
automatically.

This has enabled me to simplify the rather complicated handshake in Host::RunShellCommand. I have
left handling of MonitorDebugServerProcess (my original motivation for this change) to a separate
commit to reduce the scope of this change.

Summary:
TestExitDuringStep was very rarely hanging on the buildbots. I can't be sure, but I believe this
was because of the fact that it declared its pseudo_barrier variable as "volatile int", which is
not sufficient to guarantee corectness (also, all other tests used atomic variables for this, and
they were passing reliably AFAIK). Besides switching to an atomic variable in this test as well,
I have also took this opportunity to unify all the copies of the pseudo_barrier code to a single
place to reduce the chance of this happening again.

Jim Ingham 9b8eb155d8 Fix the way the ShouldStopHere checker handles the general case of "stepping through line 0 code".
That's good 'cause it means all the different kinds of source line stepping won't leave user in the middle of
compiler implementation code or code inlined from odd places, etc.  But it turns out that the compiler
also marks functions it MIGHT inline as all being of line 0.  That would mean we single step through this code
instead of just stepping out.  That is both inefficient, and more error prone 'cause these little nuggets tend
to be bits of hand-written assembly and the like and are hard to step through.

This change just checks and if the entire function is marked with line 0, we step out rather than step through.

"Allow LanguageRuntimes to return an error if they fail in the course of dynamic type discovery

This is not meant to report that a value doesn't have a dynamic type - it is only meant as a mechanism to propagate actual type discovery issues (e.g. malformed type metadata for languages that have such a notion)

This information is used by ValueObjectDynamic to set its own m_error, which is a fairly sharp and heavyweight tool to begin with

For the time being, this is an architectural improvement but a practical no-op as no existing runtimes are actually setting errors"

SymbolFileDWARF, which is overriden in DWO to do the right thing.

Enrico Granata 5ee5408625 Allow LanguageRuntimes to return an error if they fail in the course of dynamic type discovery
This is not meant to report that a value doesn't have a dynamic type - it is only meant as a mechanism to propagate actual type discovery issues (e.g. malformed type metadata for languages that have such a notion)

This information is used by ValueObjectDynamic to set its own m_error, which is a fairly sharp and heavyweight tool to begin with

For the time being, this is an architectural improvement but a practical no-op as no existing runtimes are actually setting errors

Adrian McCarthy 3f99810787 XFail TestLambdas.py on Windows after fixing some of the problems
1. Fixed semicolon placement in the lambda in the test itself.

2. Fixed lldbinline tests in general so that we don't attempt tests on platforms that don't use the given type of debug info. (For example, no DWO tests on Windows.) This fixes one of the two failures on Windows. (TestLambdas.py was the only inline test that wasn't XFailed or skipped on Windows.)

3. Set the error string in IRInterpreter::CanInterpret so that the caller doesn't print (null) instead of an explanation. I don't entirely understand the error, so feel free to suggest a better wording.

4. XFailed the test on Windows. The interpreter won't evaluate the lambda because the module has multiple function bodies. I don't exactly understand why that's a problem for the interpreter nor why the problem arises only on Windows.

We don't want a mutex in debugger as it will cause A/B locking issues with the lldb_private::Target's mutex, but we do need to stop two threads from doing Debugger::Clear at the same time. We have seen issues with this with the C++ global destructor chain where the global debugger list is being destroyed and the Debugger::~Debugger() is calling it while another thread was in the middle of running that function.

Jason Molenda 955dcf2dbc Add a way for an ObjectFile to indicate that assembly emulation
should not be used for this module -- for use when an ObjectFile
knows that it does not have meaningful or accurate function start
addresses.  

More commonly, it is not clear that function start addresses are
missing in a module.  There are certain cases on Mac OS X where we
can tell that a Mach-O binary has been stripped of this essential
information, and the unwinder can end up emulating many megabytes
of instructions for a single "function" in the binary.

When a Mach-O binary is missing both an LC_FUNCTION_STARTS load 
command (very unusual) and an eh_frame section, then we will assume 
it has also been stripped of symbols and that instruction emulation
will not be useful on this module.

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.

Summary:
Building HEAD of LLDB fails in linking against DebugInfoPDB. It also prints the following warning:

```
CMake Warning (dev) in source/Plugins/SymbolFile/PDB/CMakeLists.txt:
  Policy CMP0022 is not set: INTERFACE_LINK_LIBRARIES defines the link
  interface.  Run "cmake --help-policy CMP0022" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.

  Target "lldbPluginSymbolFilePDB" has an INTERFACE_LINK_LIBRARIES property.
  This should be preferred as the source of the link interface for this
  library but because CMP0022 is not set CMake is ignoring the property and
  using the link implementation as the link interface instead.

  INTERFACE_LINK_LIBRARIES:

    LLVMDebugInfoPDB

  Link implementation:

    (empty)
```

CMP0022 was introduced in CMake-2.8.11, bump minimal required version from 2.8 to 3.0 to gain more useful features like libexecinfo(3) detection on NetBSD.

In templated const functions, trying to run an expression would produce the
error

error: out-of-line definition of '$__lldb_expr' does not match any declaration
in 'foo' member declaration does not match because it is const qualified
error: 1 error parsing expression

which is no good.  It turned out we don't actually need to worry about "const,"
we just need to be consistent about the declaration of the expression and the
FunctionDecl we inject into the class for "this."

Also added a test case.
