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.

and Frames in the multithreaded_queue. The listener_func has
more computational load, which may be latter executed than the
pop leading to the failure. This patch tries to only check for
frames in listener_func as presence of frames also confirms 
prescence of threads and avoids the second push into the

Pavel Labath ebc7135f8e Fix race in TestExitDuringStep and unify pseudo_barrier handling
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.

Todd Fiala 57a4e5b3d0 Fix TestEvents.py on OS X
This change addresses a hang/segfault in TestEvents.py. The threads that
run the listener loops now do an SBListener.Clear() before they wrap up
their work. This prevents the test from trying to clean up the
SBListener too late.

There is a separate issue here which is that we should prevent this
clean-up time lock-up, but that is out of scope for this particular
change. I'd like to get these tests back and running the normal flow
rather than skipping them.

This addresses:

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.

This change moves all the test event handling and its related
ResultsFormatter classes out of the packages/Python/lldbsuite/test dir
into a packages/Python/lldbsuite/test_event package. Formatters are
moved into a sub-package under that.

I am limiting the scope of this change to just the motion and a few
minor issues caught by a static Python checker (e.g. removing unused
import statements).

This is a pre-step for adding package-level tests to the test event
system. I also intend to simplify test event results formatter selection
after I make sure this doesn't break anybody.

I have modified FileSpec::ResolveUsername (llvm::SmallVectorImpl<char> &path) to deal with the cases where llvm::sys::path::home_directory() returns false by digging a little further on unix systems and setting "HOME" in the environment so that subsequent calls to llvm::sys::path::home_directory() will succeed.
I also added a test to ensure we don't regress.

Todd Fiala ca5793ea5c test infra cleanup: convert test_runner lib into package
Also does the following:
* adopts PEP8 naming convention for OptionalWith class (now
  optional_with).
* moves test_runner/lldb_utils.py to lldbsuite/support/optional_with.py.
* packages tests in a subpackage of test_runner per recommendations in
  http://the-hitchhikers-guide-to-packaging.readthedocs.org/en/latest/creation.html

Tests can be run from within pacakges/Python/lldbsuite/test via this
command:

  python -m unittest discover test_runner

The primary cleanup this allows is avoiding the need to muck with the
PYTHONPATH variable from within the source files.  This also aids some
of the static code checkers as they don't need to run code to determine
the proper python path.

Todd Fiala 430309f13a fix a race is the LLDB test suite results collection
The race boiled down to this:

If a test worker queue is able to run the test inferior and
clean up before the dosep.py listener socket is spun up, and
the worker queue is the last one (as would be the case when
there's only one test rerunning in the rerun queue), then
the test suite will exit the main loop before having a chance
to process any test events coming from the test inferior or
the worker queue job control.

I found this race to be far more likely on fast hardware.
Our Linux CI is one such example.  While it will show
up primarily during meta test events generated by
a worker thread when a test inferior times out or
exits with an exceptional exit (e.g. seg fault), it only
requires that the OS takes longer to hook up the
listener socket than it takes for the final test inferior
and worker thread to shut down.

Pavel Labath 5c17454cd6 Make destructor breakpoint location test more resilient
Summary:
The original breakpoint location test was failing for linux, because the compilers here tend to
merge the full-object and subobject destructors even at -O0 (as a result, we are getting only 2
breakpoint locations, and not 4 as the test expected. The fixup in r266164 substantially weakened
the test, as it now did not check whether both kinds of destructors were being found.

Because of these contraints, I have altered the logic of the test. It sets the
breakpoint by name, and then independently verifies that the breakpoint is set on the correct
demangled symbol name (which is not very meaningful since both kinds of destructors demangle to
the same name) *and* the correct symbol address (which is obtained by looking up the mangled
symbol name).

Ulrich Weigand 7e8de59b90 Fix test cases for big-endian systems
A number of test cases were failing on big-endian systems simply due to
byte order assumptions in the tests themselves, and no underlying bug
in LLDB.

These two test cases:
  tools/lldb-server/lldbgdbserverutils.py
  python_api/process/TestProcessAPI.py
actually check for big-endian target byte order, but contain Python errors
in the corresponding code paths.

These test cases:
  functionalities/data-formatter/data-formatter-python-synth/TestDataFormatterPythonSynth.py

  functionalities/data-formatter/synthcapping/TestSyntheticCapping.py

could be fixed to check for big-endian target byte order and update the
expected result strings accordingly.  For the two synthetic tests, I've
also updated the source to make sure the fake_a value is always nonzero
on both big- and little-endian platforms.

These test case:

Ulrich Weigand 377e4213e1 Fixes for platforms that default to unsigned char
This fixes several test case failure on s390x caused by the fact that
on this platform, the default "char" type is unsigned.

- In ClangASTContext::GetBuiltinTypeForEncodingAndBitSize we should return
  an explicit *signed* char type for encoding eEncodingSint and bit size 8,
  instead of the default platform char type (which may be unsigned).
  This fix matches existing code in ClangASTContext::GetIntTypeFromBitSize,
  and fixes the TestClangASTContext.TestBuiltinTypeForEncodingAndBitSize
  unit test case.

- The test/expression_command/char/TestExprsChar.py test case is known to
  fail on platforms defaulting to unsigned char (pr23069), and just needs
  to be xfailed on s390x like on arm.

- The test/functionalities/watchpoint/watchpoint_on_vectors/main.c test
  case defines a vector of "char" and implicitly assumes to be signed.
  Use an explicit "signed char" instead.

Ulrich Weigand bb00d0b6b2 Support Linux on SystemZ as platform
This patch adds support for Linux on SystemZ:
- A new ArchSpec value of eCore_s390x_generic
- A new directory Plugins/ABI/SysV-s390x providing an ABI implementation
- Register context support
- Native Linux support including watchpoint support
- ELF core file support
- Misc. support throughout the code base (e.g. breakpoint opcodes)
- Test case updates to support the platform

This should provide complete support for debugging the SystemZ platform.
Not yet supported are optional features like transaction support (zEC12)
or SIMD vector support (z13).

There is no instruction emulation, since our ABI requires that all code
provide correct DWARF CFI at all PC locations in .eh_frame to support
unwinding (i.e. -fasynchronous-unwind-tables is on by default).

The implementation follows existing platforms in a mostly straightforward
manner.  A couple of things that are different:

- We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers,
  since some registers (access register) reside at offsets in the user area
  that are multiples of 4, but the PTRACE_PEEKUSER interface only allows
  accessing aligned 8-byte blocks in the user area.  Instead, we use a s390
  specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that
  allows accessing a whole block of the user area in one go, so in effect
  allowing to treat parts of the user area as register sets.

- SystemZ hardware does not provide any means to implement read watchpoints,
  only write watchpoints.  In fact, we can only support a *single* write
  watchpoint (but this can span a range of arbitrary size).  In LLDB this
  means we support only a single watchpoint.  I've set all test cases that
  require read watchpoints (or multiple watchpoints) to expected failure
  on the platform.  [ Note that there were two test cases that install
  a read/write watchpoint even though they nowhere rely on the "read"
  property.  I've changed those to simply use plain write watchpoints. ]

Pavel Labath 9fb77fcfef Fix test rerun logic
result_formatter used inspect.getfile() to get the python file name, which returned "*.pyc" if
the bytecode file was present. This resulted in files being displayed with the wrong extension,
and more critically, would confuse the rerun logic because it would try to rerun the pyc file
(which resulted in an empty rerun list as unittest refused to run those).

Fix: use inspect.getsourcefile() instead.

I am not sure why does was not an issue before. I can only assume that some system update
tricked python into producing bytecode files more aggressively.

Jim Ingham ff7ac6a7b9 Breakpoint conditions were making result variables, which they should not do.
The result variables aren't useful, and if you have a breakpoint on a
common function you can generate a lot of these.  So I changed the
code that checks the condition to set ResultVariableIsInternal in the
EvaluateExpressionOptions that we pass to the execution.
Unfortunately, the check for this variable was done in the wrong place
(the static UserExpression::Evaluate) which is not how breakpoint
conditions execute expressions (UserExpression::Execute).  So I moved
the check to UserExpression::Execute (which Evaluate also calls) and made the
overridden method DoExecute.

This test sets the compiler optimization level to -O1 and
makes some assumptions about how local frame vars will be
stored (i.e. in registers).  These assumptions are not always
true.

I did a first-pass set of improvements that:
(1) no longer assumes that every one of the target locations has
    every variable in a register.  Sometimes the compiler
    is even smarter and skips the register entirely.
(2) simply expects one of the 5 or so variables it checks
    to be in a register.

This test probably passes on a whole lot more systems than it
used to now.  This is certainly true on OS X.

Summary:
There was a bug in linux core file handling, where if there was a running process with the same
process id as the id in the core file, the core file debugging would fail, as we would pull some
pieces of information (ProcessInfo structure) from the running process instead of the core file.
I fix this by routing the ProcessInfo requests through the Process class and overriding it in
ProcessElfCore to return correct data.

A (slightly convoluted) test is included.

This helps solve a class of problems on OS X where LLDB would try to launch via sh, and run into problems if the command line being passed to the inferior contained such special markers (hint: the shell would error out and we'd fail to launch)
This makes those launch scenarios work transparently via shell expansion

Pavel Labath 3f081c8210 Don't vary debug info for lldb-server tests
Summary:
Debug info is used only by the client and lldb-server tests do not even have the client component
running, as they communicate with the server directly. Therefore, running the tests for each
debug info type is unnecessarry.

This adds general ability to mark a test class as not dependent on debug info, and marks all
lldb-server tests as such.

Pavel Labath ec62c0559f Fix flakyness in TestWatchpointMultipleThreads
Summary:
the inferior in the test deliberately does not lock a mutex when accessing the watched variable.
The reason for that is unclear as, based on the logs, the original intention of the test was to
check whether watchpoints get propagated to newly created threads, which should work fine even
with a mutex. Furthermore, in the unlikely event (which I have still observed happening from time
to time) that two threads do manage the execute the "critical section" simultaneously, the test
will fail, as it is expecting the watchpoint "hit count" to be 1, but in this case it will be 2.

Given this, I have simply chose to lock the mutex always, so that we have more predictible
behavior. Watchpoints being hit simultaneously is still (and correctly!) tested by
TestConcurrentEvents.

Greg Clayton 3de2a90574 Fixed the failing test TestCommandScriptImmediateOutput on MacOSX. Turns out that there are few things to watch out for when writing pexpect tests:
1 - If you plan on looking for the "(lldb) " prompt as a regular expression, look for "\(lldb\) " so you don't just find "lldb".
2 - Make sure to not use colors (specify --no-use-colors as an option to lldb when launching it) as our editline will print:

"(lldb) <color junk>(lldb) "

where "<color junk>" is a work around that is used to allow us to colorize our prompts. The bad thing is this will make pexepct code like this not execute as you would expect:

prompt = "\(lldb\) "
self.child.sendline("breakpoint set ...", prompt)
self.child.sendline("breakpoint clear ...", prompt)

The problem is the first "sendline" will create two lldb prompts and will match both the first and second prompts and you output will get off. So be sure to disable colors if you need to.

Fixed a case where "TestCommandScriptImmediateOutput.py" would fail if you have spaces in your directory names. I modified custom_command.py to use shlex to parse arguments and I quoted the file path we sent down to the custom_command.write_file function.

Also, moved the retry into ClangUserExpression::Evaluate, where I can make a whole new ClangUserExpression

Sean Callanan 863fab69a2 Expose top-level Clang expressions via the command line and the API.
Top-level Clang expressions are expressions that act as new translation units,
and define their own symbols.  They do not have function wrappers like regular
expressions do, and declarations are persistent regardless of use of the dollar
sign in identifiers.  Names defined by these are given priority over all other
symbol lookups.

This patch adds a new expression option, '-p' or '--top-level,' which controls
whether the expression is treated this way.  It also adds a flag controlling 
this to SBExpressionOptions so that this API is usable externally.  It also adds
a test that validates that this works.  (The test requires a fix to the Clang
AST importer which I will be committing shortly.)

Jim Ingham a1e541bf9f Use Clang's FixItHints to correct expressions with "trivial" mistakes (e.g. "." for "->".)
This feature is controlled by an expression command option, a target property and the
SBExpressionOptions setting.  FixIt's are only applied to UserExpressions, not UtilityFunctions,
those you have to get right when you make them.

This is just a first stage.  At present the fixits are applied silently.  The next step
is to tell the user about the applied fixit.

Kuba Brecka 6a83143650 Add ThreadSanitizer debugging support.
This patch adds ThreadSanitizer support into LLDB:
- Adding a new InstrumentationRuntime plugin, ThreadSanitizerRuntime, in the same way ASan is implemented.
- A breakpoint stops in `__tsan_on_report`, then we extract all sorts of information by evaluating an expression. We then populate this into StopReasonExtendedInfo.
- SBThread gets a new API, SBThread::GetStopReasonExtendedBacktraces(), which returns TSan’s backtraces in the form of regular SBThreads. Non-TSan stop reasons return an empty collection.
- Added some test cases.

Sean Callanan 579e70c9b0 Add a DiagnosticManager replace error streams in the expression parser.
We want to do a better job presenting errors that occur when evaluating
expressions. Key to this effort is getting away from a model where all
errors are spat out onto a stream where the client has to take or leave
all of them.

To this end, this patch adds a new class, DiagnosticManager, which
contains errors produced by the compiler or by LLDB as an expression
is created. The DiagnosticManager can dump itself to a log as well as
to a string. Clients will (in the future) be able to filter out the
errors they're interested in by ID or present subsets of these errors
to the user.

This patch is not intended to change the *users* of errors - only to
thread DiagnosticManagers to all the places where streams are used. I
also attempt to standardize our use of errors a bit, removing trailing
newlines and making clients omit 'error:', 'warning:' etc. and instead
pass the Severity flag.

The patch is testsuite-neutral, with modifications to one part of the
MI tests because it relied on "error: error:" being erroneously
printed. This patch fixes the MI variable handling and the testcase.

Pavel Labath 78fc483980 [test] Persist packets between expect_gdbremote_sequence invocations
Summary:
Some tests (Hc_then_Csignal_signals_correct_thread, at least) were sending a "continue" packet in
one expect_gdbremote_sequence invocation, and "expecting" the stop-reply in another call. This
posed a problem, because the were packets were not persisted between the two invocations, and if
the stub was exceptionally fast to respond, the packet would be received in the first invocation
(where it would be ignored) and then the second invocation would fail because it could not find
the packet.

Since doing matching in two invocations seems like a reasonable use of the packet pump, instead
of fixing the test, I make sure the packet_pump supports this usage by making the list of
captured packets persistent.

Enrico Granata ab2b0cb992 On some platforms, the compiler is allowed to assume that BOOL == bool. On others, BOOL == signed char.
This can cause differences in which bit patterns end up meaning YES or NO. In general, however, 0 == NO and 1 == YES.

To keep it simple, LLDB will now show "YES" and "NO" only for 1 and 0 respectively, and format other values as the plain numeric value instead.
