Jim Ingham e5ee6f04ab Figure out what the fixed expression is, and print it. Added another target setting to
quietly apply fixits for those who really trust clang's fixits.

Also, moved the retry into ClangUserExpression::Evaluate, where I can make a whole new ClangUserExpression 
to do the work.  Reusing any of the parts of a UserExpression in situ isn't supported at present.

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.

This can cause differences in which bit patterns end up meaning YES or NO. In general, however, 0 == NO and 1 == YES.

Sean Callanan bbde9083ad Made self.expect() errors a little more readable in the testsuite.
self.expect() had two problems:

- If there was a substrs argument, then it overwrote the variable containing
  the command to run with the last substr.  That meant nonsense command text in
  testsuite errors.

- The actual output is not printed, which makes fixing testsuite failures a bit
  annoying (you end up having to use the -tv arguments to dotest).

This fixes both of these issues.  We could do even better, pretty-printing the
criteria for "correct" output, but this at least makes dealing with errors a bit
better.

Adrian Prantl 6aeba89e89 Support floating point values in 128-bit SSE vector registers
The System-V x86_64 ABI requires floating point values to be passed
in 128-but SSE vector registers (xmm0, ...). When printing such a
variable this currently yields an <invalid load address>.

This patch makes LLDB's DWARF expression evaluator accept 128-bit
registers as scalars. It also relaxes the check that the size of the
result of the DWARF expression be equal to the size of the variable to a
greater-than. DWARF defers to the ABI how smaller values are being placed
in a larger register.

Implementation note: I found the code in Value::SetContext() that changes
the m_value_type after the fact to be questionable. I added a sanity check
that the Value's memory buffer has indeed been written to (this is
necessary, because we may have a scalar value in a vector register), but
really I feel like this is the wrong place to be setting it.

Adrian McCarthy 536183275d Fix TestInlines.py on Windows
The inlining semantics for C and C++ are different, which affects the test's expectation of the number of times the function should appear in the binary.  In the case of this test, C semantics means there should be three instances of inner_inline, while C++ semantics means there should be only two.

On Windows, clang uses C++ inline semantics even for C code, and there doesn't seem to be a combination of compiler flags to avoid this.

So, for consistency, I've recast the test to use C++ everywhere.  Since the test resided under lang/c, it seemed appropriate to move it to lang/cpp.

This does not address the other XFAIL for this test on Linux/gcc.  See https://llvm.org/bugs/show_bug.cgi?id=26710

Adrian McCarthy 0a750820a3 Get register context for the 32-bit process in a WoW64 process minidump
32-bit processes on 64-bit Windows run in a layer called WoW64 (Windows-on-Windows64). If you capture a mini dump of such a process from a 32-bit debugger, you end up with a register context for the 64-bit WoW64 process rather than the 32-bit one you probably care about.

This detects WoW64 by looking to see if there's a module named wow64.dll loaded. For such processes, it then looks in the 64-bit Thread Environment Block (TEB) to locate a copy of the 32-bit CONTEXT record that the plugin needs for the register context.

Added some rudimentary tests.  I'd like to improve these later once we figure out how to get the exception information from these mini dumps.

Paths on Windows are not case-sensitive.  Because of this, if a file

by using the name Main.cpp.  In an ideal world, you could just
tell people to match the case, but in practice this can be a real
problem as it requires you to know whether the person who compiled
the program ran "clang++ main.cpp" or "clang++ Main.cpp", both of
which would work, regardless of what the file was actually called.

Enrico Granata 2543d29048 The data formatters for NSArray, NSDictionary and (only partially) NSSet contain logic to inspect the objects without running code.
However, they also contain fallback logic that - in cases where LLDB can't recognize the specific subclass - actually does run code in order to inspect those objects.

The argument for this logic was that these data types are critical enough that the risk of getting it wrong is outweighed by the advantage of always providing accurate child information.

Practical experience however shows that "po" - a code running data-inspection command - is quite frequently used, and not considered burdensome by users.
As such, this makes the code-running fallback in the data formatters a risk that carries very little actual reward. Also, unlike the time this code was originally written, we now have accurate class information for Objective-C, and thus we are less likely to improperly identify classes.

This commit removes support for the code-running fallback, and aligns the data formatters for NSArray, NSDictionary and NSSet to the general no-code-running behavior of other data formatters.

While it is possible for us to add support for some subclasses that are now no longer covered by static inspection alone, this is beyond the scope of this commit.

Jim Ingham 0ea010aecb When calling TypeSystemMap::Clear, objects being destroyed in the process of
clearing the map ended up calling back into the TypeSystemMap to do lookups.  
Not a good idea, and in this case it would cause a deadlock.

You would only see this when replacing the target contents after an exec, and only if you 
had stopped before the exec, evaluated an expression, then continued
on to the point where you did the exec.  

Fixed this by making sure the TypeSystemMap::Clear tears down the TypeSystems in the map before clearing the map.
I also add an expression before exec to the TestExec.py so that we'll catch this
issue if it crops up again in the future.

Siva Chandra 375882dddb Use an artifical namespace so that member vars do not hide local vars.
Summary:
While evaluating expressions when stopped in a class method, there was a
problem of member variables hiding local variables. This was happening
because, in the context of a method, clang already knew about member
variables with their name and assumed that they were the only variables
with those names in scope. Consequently, clang never checks with LLDB
about the possibility of local variables with the same name and goes
wrong. This change addresses the problem by using an artificial
namespace "$__lldb_local_vars". All local variables in scope are
declared in the "$__lldb_expr" method as follows:

    using $__lldb_local_vars::<local var 1>;
    using $__lldb_local_vars::<local var 2>;
    ...

This hides the member variables with the same name and forces clang to
enquire about the variables which it thinks are declared in
$__lldb_local_vars. When LLDB notices that clang is enquiring about
variables in $__lldb_local_vars, it looks up local vars and conveys
their information if found. This way, member variables do not hide local
variables, leading to correct evaluation of expressions.

A point to keep in mind is that the above solution does not solve the
problem for one specific case:

    namespace N
    {
        int a;
    }

    class A
    {
    public:
        void Method();
        int a;
    };

    void
    A::Method()
    {
        using N::a;
        ...

        // Since the above solution only touches locals, it does not
        // force clang to enquire about "a" coming from namespace N.
    }

My eventual goal is to move all of the test decorators to their
own module such as `decorators.py`.  But some of the decorators
use existing functions in `lldbtest.py` and conceptually the
functions are probably more appropriately placed in lldbplatformutil.
Moreover, lldbtest.py is a huge file with a ton of random utility
functions scattered around, so this patch also workds toward the
goal of reducing the footprint of this one module to a more
reasonable size.

So this patch moves some of them over to lldbplatformutil with the
eventual goal of moving decorators over to their own module.

Zachary Turner e5a7990dbe Always write the session file in UTF-8.
This patch attempts to solve the Python 2 / Python 3 incompatibilities by
introducing a new `encoded_file` abstraction that we use instead of
`io.open()`.  The problem with the builtin implementation of `io.open` is
that `read` and `write` accept and return `unicode` objects, which are not
always convenient to work with in Python 2.  We solve this by making
`encoded_file.open()` return the same object returned by `io.open()` but
with hooked `read()` and `write()` methods.  These hooked methods will
accept binary or text data, and conditionally convert what it gets to a
`unicode` object using the correct encoding.  When calling `read()` it

Abhishek Aggarwal c2c8ca1ce3 Set correct ThreadStopInfo in case of trace event
Summary:
 - The patch solves Bug 23478 and Bug 19311. Resolving
   Bug 23478 also resolves Bug 23039.
      Correct ThreadStopInfo is set for Linux and FreeBSD
      platforms.

 - Summary:
      When a trace event is reported, we need to check
      whether the trace event lands at a breakpoint site.

      If it lands at a breakpoint site then set the thread's
      StopInfo with the reason 'breakpoint'. Else, set the reason
      to be 'Trace'.

Zachary Turner 7289e43831 Refactor some of the xfail / skip decorators to share logic.
Previously the logic of skipIf and expectedFailure were 99%
the same, but they took different sets of arguments since they
were maintained separately, and had slightly differences in
their behavior.  This makes everything consistent, there is now
only one real implementation, and the previous ones are changed

Zachary Turner 00b87282cd Write the session log file in UTF-8.
Previously we were writing in the default encoding, which depends

On Python 3, this would lead to a situation where writing unicode
text to the log file generates an exception.  The fix here is to
write session logs using the proper encoding, which incidentally
fixes another test, so xfail is removed from that.

Zachary Turner 4407396fb9 Fix some issues with bytes and strings in Python 3.
SBProcess::ReadMemory and other related functions such as
WriteMemory are returning Python string() objects.  This means
that in Python 3 that are returning Unicode objects.  In reality
they should be returning bytes objects which is the same as a string
in Python 2, but different in Python 3.  This patch updates the
generated SWIG code to return Python bytes objects for all
memory related functions.

One quirk of this patch is that the C++ signature of ReadCStringFromMemory
has it writing c-string data into a void*.  This confuses our swig
typemaps which expect that a void* means byte data.  So I hacked up
a custom typemap which maps this specific function to treat the
void* as string data instead of byte data.

Zachary Turner 1da094a5ec More fixes related to counting threads on Windows.
The Windows 10 loader spawns threads at startup, so
tests which count threads or assume that a given user
thread will be at a specific index are incorrect in
this case.  The fix here is to use the standard mechanisms
for getting the stopped thread (which is all we are
really interested in anyway) and correlating them with
the breakpoints that were set, and doing checks against
those things.

This fixes about 6 tests on Windows 10.

Zachary Turner 783550be62 Remove assumptions that thread 0 is always the main thread.
Starting with Windows 10, the Windows loader is itself multi-threaded,
meaning that the loader spins up a few threads to do process
initialization before it executes main.  Windows delivers these
notifications asynchronously and they can come out of order, so
we can't be sure that the first thread we get a notification about
is actually the zero'th thread.

This patch fixes this by requesting the thread stopped at the
breakpoint that was specified, rather than getting thread 0 and
verifying that it is stopped at a breakpoint.

Summary:
We already have the ability to collect the server logs when doing local debugging. This enables
the collection of remote logs as well. This relies on specifying a relative path "server.log" for
LLDB_DEBUGSERVER_LOG_FILE when starting remote platform. Since we always set the platform working
directory to a fresh folder to avoid conflicts, the actual file path will always be different and
we can pick the logs up from there.

Zachary Turner 19e2ea8fb6 Fix TestProcessLaunch for Python 3.
There were a number of problems preventing this from working:

1. The SWIG typemaps for converting Python lists to and from C++
   arrays were not updated for Python 3.  So they were doing things
   like PyString_Check instead of using the PythonString from
   PythonDataObjects.
2. ProcessLauncherWindows was ignoring the environment completely.
   So any test that involved launching an inferior with any kind
   of environment variable would have failed.
3. The test itself was using process.GetSTDOUT(), which isn't
   implemented on Windows.  So this was changed to save the
   value of the environment variable in a local variable and
   have the debugger look at the value of the variable.

Ravitheja Addepally 49982f5773 Fix for TestNoreturnUnwind.py on i386
Summary:
The testcase TestNoreturnUnwind.py was failing
because the unwind from the vdso library was not
successful for clang compiler while it was passing
for gcc. It was passing for gcc since the unwind plan
used was the assembly plan and the ebp register was
set by the main function in case of gcc and was not
used by the functions in the call flow to the vdso, whereas
clang did not emit assembly prologue for main and so
 the assembly unwind was failing. Normally in case of
failure of assembly unwind, lldb switches to EH CFI frame
based unwinding, but this was not happening for
the first frame. This patch tries to fix this behaviour by
falling to EH CFI frame based unwinding in case of assembly
unwind failure even for the first frame.
The test is still marked as XFAIL since it relys on the fix
of another bug.

Summary:
On linux we need the process to give us special permissions before we can attach to it.
Previously, the code for this was copied into every file that needed it. This moves the code to a
central place to reduce code duplication.

Jim Ingham 58a305bf15 Fiddling with Pavel's fix for getting the breakpoint right when there's debug info for sleep.
I prefer to use "-p" over using line_number and then setting by line because it's makes it possible
to see what the breakpoint is at the site where you make the breakpoint.  So I switched
it back to -p but specified the source file as well, which is an "all within lldb" way of doing
what Pavel's fix did.

Pavel Labath eceec6dd01 Fix TestBatchMode on linux
New test introduced in r257120 was failing on linux. The reason for that the regex for setting

containing the definition of the sleep() syscall (because after attach, we are stopped in the
sleep function). I have changed this use the more customary way of setting the breakpoint and
specifying the source file name explicitly.

Jim Ingham 962260c852 Fix a glitch in the Driver's batch mode when used with "attach".
Batch mode is supposed to stop execution and return control to the user when an
exceptional stop occurs (crash, signal or instrumentation).  But attach always stops
with a SIGSTOP on OSX (maybe on Linux too?) which would short circuit the rest of the
commands given.

This change allows a command result object to indicate that it expected to leave the 
process stopped with an exceptional stop reason, and it is okay for batch mode to keep going.

Dawn Perchik 954b40bf63 Add support for "source info" and use it to fix MI's -symbol-list-lines.
This patch adds support the command 'source info' as follows:
    (lldb) help source info
         Display source line information (as specified) based on the current executable's
         debug info.
    
    Syntax: source info <cmd-options>
    
    Command Options Usage:
      source info [-c <count>] [-s <shlib-name>] [-f <filename>] [-l <linenum>] [-e <linenum>]
      source info [-c <count>] [-s <shlib-name>] [-n <symbol>]
      source info [-c <count>] [-a <address-expression>]
    
           -a <address-expression> ( --address <address-expression> )
                Lookup the address and display the source information for the corresponding
                file and line.
    
           -c <count> ( --count <count> )
                The number of line entries to display.
    
           -e <linenum> ( --end-line <linenum> )
                The line number at which to stop displaying lines.
    
           -f <filename> ( --file <filename> )
                The file from which to display source.
    
           -l <linenum> ( --line <linenum> )
                The line number at which to start the displaying lines.
    
           -n <symbol> ( --name <symbol> )
                The name of a function whose source to display.
    
           -s <shlib-name> ( --shlib <shlib-name> )
                Look up the source in the given module or shared library (can be specified
                more than once).
For example:
    (lldb) source info --file x.h
    Lines for file x.h in compilation unit x.cpp in `x
    [0x0000000100000d00-0x0000000100000d10): /Users/dawn/tmp/./x.h:10
    [0x0000000100000d10-0x0000000100000d1b): /Users/dawn/tmp/./x.h:10

The new options are used to fix the MI command:
    -symbol-list-lines <file>
which didn't work for header files because it called:
    target modules dump line-table <file>
which only dumps line tables for a compilation unit.

The patch also fixes a bug in the error reporting when no files were supplied to the command. Previously you'd get:
    (lldb) target modules dump line-table
    error:
    Syntax:
    error: no source filenames matched any command arguments
Now you get:
    error: file option must be specified.

This is the listener's spawned connection, not the listener itself.
(i.e. this is the test runner's receiving side of test event sockets).
A standard socket.error will just issue an INFO statement and continue.
Something other than a socket.error will get an ERROR: printed (and
also continue).

Todd Fiala 685a7570ec test infra: enable single-worker rerun phase for flakey tests.
Use of --rerun-all-issues will enable any test method failure, not just
test methods marked with the flakey decorator, to rerun.

Currently this does not change the flakey logic's immediate rerun
attempt.  I want to make sure this doesn't cause any significant issues
before changing that part.

The rerun reporting is only known to work properly with the
default (new) BasicResultsFormatter reporting.  Once we work out
any issues, I'll go back and make sure the curses output handles
it properly as well.

Pavel Labath ffbf9e86b2 Make test categories composable
Summary:
Previously the add_test_categories would simply overwrite the current set of categories for a
method. This change makes the decorator truly "add" categories, by extending the current set of
categories instead of replacing it.

To do this, I have:
- replaced the getCategories() property on a method (which was itself a method), with a simple
  list property "categories". This makes add_test_categories easier to implement, and test
  categories isn't something which should change between calls anyway.
- rewritten the getCategoriesForTest function to merge method categories with the categories of
  the test case. Previously, it would just use the method categories if they were present. I have
  also greatly simplified this method. Originally, it would use a lot of introspection to enable
  it being called on various types of objects. Based on my tests, it was only ever being called
  on a test case. The new function uses much less introspection then the preivous one, so we
  should easily catch any stray uses, if there are any, as they will generate exceptions now.

Dawn Perchik b59257841e Fix scope-based lookup when more than one function is found.
When multiple functions are found by name, lldb removes duplicate entries of
functions with the same type, so the first function in the symbol context list
is chosen, even if it isn't in scope. This patch uses the declaration context
of the execution context to select the function which is in scope.

This fixes cases like the following:

    int func();
    namespace ns {
	int func();
	void here() {
	    // Run to BP here and eval 'p func()';
	    // lldb used to find ::func(), now finds ns::func().
	}
    }

If a timeout or exceptional exit happens while a test method is running

reported against that test method.  Otherwise, if no test method was
running at the time of the timeout or exceptional exit, only the test
filename will be reported as the TIMEOUT or ERROR.

Tamas Berghammer ccd6cffba3 Modify "platform connect" to connect to processes as well
The standard remote debugging workflow with gdb is to start the
application on the remote host under gdbserver (e.g.: gdbserver :5039
a.out) and then connect to it with gdb.

The same workflow is supported by debugserver/lldb-gdbserver with a very
similar syntax but to access all features of lldb we need to be
connected also to an lldb-platform instance running on the target.

Before this change this had to be done manually with starting a separate
lldb-platform on the target machine and then connecting to it with lldb
before connecting to the process.

This change modifies the behavior of "platform connect" with
automatically connecting to the process instance if it was started by
the remote platform. With this command replacing gdbserver in a gdb
based worflow is usually as simple as replacing the command to execute
gdbserver with executing lldb-platform.

Zachary Turner 606e3a5221 Get rid of global variables in dotest.py
This moves all the global variables into a separate module called
`configuration`.  This has a number of advantages:

1. Configuration data is centrally maintained so it's easy to get
   a high level overview of what configuration data the test suite
   makes use of.
2. The method of sharing configuration data among different parts
   of the test suite becomes standardized.  Previously we would
   put some things into the `lldb` module, some things into the
   `lldbtest_config` module, and some things would not get shared.
   Now everything is shared through one module and is available to
   the entire test suite.
3. It opens the door to moving some of the initialization code into
   the `configuration` module, simplifying the implementation of
   `dotest.py`.

There are a few stragglers that didn't get converted over to using
the `configuration` module in this patch, because it would have grown
the size of the patch unnecessarily.  This includes everything
currently in the `lldbtest_config` module, as well as the
`lldb.remote_platform` variable.  We can address these in the future.

- Fix ClangASTSource::CompleteType() to check the decl context of types that it finds by basename to ensure we don't complete a type "S" with a type like "std::S". Before this fix ClangASTSource::CompleteType() would accept _any_ type that had a matching basename and copy it into the other type.

This is a resubmit of r254403, see that commit's message for context. This fixes an issue in the
original commit, where we would incorrectly interrupt the process if the interrupt request came

Pavel Labath cb8ea4bd23 Make TestThreadStates more stable
Summary:
Because of the large number of XFAILs TestThreadStates has decayed quite a bit. This commit does
the following:
- removes the "breakpoint list" expectations. Most tests have been failing on this, because the
  command output changed quite a while back. I remove it, because run_break_set_by_file_and_line
  already does a decent amount of checking
- fixup test_state_after_expression: this was calling the wrong function by mistake. As now the
  function actually tests something (which we know is broken), I needed to XFAIL it as well.
- replaces the sleep() with a proper wait-for-event functionality in parts which use async mode,
  to stabilize the one function that actually tests something.

Zachary Turner 3e9e7d2822 Make TestThreadSpecificBreakpoint.py more focused.
This test would fail before if conditional breakpoints weren't
working correctly, and the nature of the test (spinning up 10
threads, etc) opens the door to raciness.

This patch vastly simplifies the test, removes the need for relying
on conditional expression evaluation, and as a result makes the
correctness of the test vastly easier to reason about and reduces
flakiness.

The Details header only prints if there are any issues to report.  The
Details section has tags that should get picked up using the normal
issue text scrapers (e.g. buildbot).

Test numbers reported are strictly test method runs.

The rerun bit at the top is in support of the multi-pass test
runner code (to run the low-load, single worker test pass for
tests that failed the first run), which I'll be able to put up
for review after this.

ResultsFormatters now have the ability to indicate they replace
the legacy summary, as this one does.

Once we come to agreement on the exact format, I will switch
us over to using this by default.

Abhishek Aggarwal 296e063d8f PTRACE ABI to read FXSAVE area for 32-bit inferior
Summary:
 - Problem occurs when:
    -- 32-bit inferiors run on x86_32 machine and
       the architecture doesn't have AVX feature

    -- This causes FPRType to be set to eFPRTypeFXSAVE

    -- PTRACE_GETFPREGS was being used to read FXSAVE area

    -- For 32-bit inferiors running on x86_32 machine,
       PTRACE_GETFPREGS reads FSAVE area and not FXSAVE area

 - Changed ptrace API to PTRACE_GETREGSET for 32-bit inferiors
    -- This reads FPR data in FXSAVE format.
    -- For 64-bit inferiors, no change has been made.

 - Modified XFAIL for TestReturnValue.py
    -- Earlier, this test was passing for Linux OS
    -- Now, it passes for Android OS as well

Greg Clayton 5dfc4a4d02 Added support for -gmodule debugging when debug info is left in the .o files on Darwin.
This is done by finding the types that are forward declarations that come from a module, and loading that module's debug info in a separate lldb_private::Module, and copying the type over into the current module using a ClangASTImporter object. ClangASTImporter objects are already used to copy types from on clang::ASTContext to another for expressions so the type copying code has been around for a while.

A new FindTypes variant was added to SymbolVendor and SymbolFile:

size_t
SymbolVendor::FindTypes (const std::vector<CompilerContext> &context, bool append, TypeMap& types);

size_t
SymbolVendor::FindTypes (const std::vector<CompilerContext> &context, bool append, TypeMap& types);

The CompilerContext is a way to represent the exact context of a type and pass it through an agnostic API boundary so that we can find that exact context elsewhere in another file. This was required here because we can have a module that has submodules, both of which have a "foo" type.

I am not able to add tests for this yet as we currently don't build our C/C++/ObjC binaries with the clang binary that we build. There are some driver issues where it can't find the header files for the C and C++ standard library which makes compiling these tests hard. We can't also guarantee that if we are building with clang that it supporst the exact format of -gmodule debugging that we are trying to test. We have had other versions of clang that had a different implementation of -gmodule debugging that we are no longer supporting, so we can't enable tests if we are building with clang without compiling something and looking at the structure of the DWARF that was generated to ensure that it is the format we can actually use.

Pavel Labath df55f522bd Fix race during process interruption
Summary:
The following situation was occuring in TestAttachResume:
- we did a "continue" from a breakpoint (which involves a private start-stop to step over the
  breakpoint)
- after receiving the stop-reply from the step-over, we issue a "detach" (which requires a
  process interrupt)
- at this moment, the public state is "running", private state is "about-to-be-stopped" (the
  stopped event was broadcast, but it was not received yet)
- StopForDestroyOrDetach (public thread) notes the public state is running, sends an interrupt
  request to the private thread
- private thread gets the eBroadcastBitInterrupt (before the eStateStopped message), and asks the
  process plugin to stop (via Halt())
- process plugin says it has nothing to do as the process is already stopped
- private thread shrugs and carries on. receives the stop event, restores the breakpoint and
  resumes the process.
- after a while, the public thread times out and says it failed to stop the process

This patch does the following:
- splits Halt() into two functions, private and public, their usage depends on the context
  - public Halt(): sends eBroadcastBitInterrupt to the private thread and waits for the Stop
    event
  - HaltPrivate(): asks the plugin to stop and makes a note that the halt was requested. When the
    next stop event comes it sets the interrupt flag on it.
- removes HijackPrivateProcessEvents(), as the only user (old Halt()) has gone away
- removes the m_currently_handling_event hack, as the new Halt() does not need it
- adds a use_run_lock parameter to public Halt() and WaitForProcessToStop(). This was needed
  because RunThreadPlan uses Halt() while holding the run lock and we don't want Halt() to take
  it away from him.

With this patch, the client will package up all the required
inputs into a compressed zip file, establish a connection to the

send a response (in this case the response is just echoed back to

This gets the network communication in place, and in a subsequent

Zachary Turner 7aac24805b Pass -fms-compatibility-version when building test inferiors.
-fms-compatibility-version defaults to VS 2013.  When using
VS 2015, this will lead to compilation failures of the test
inferiors in the C++ standard library for language conformance
reasons.

The fix here is to simply pass -fms-compatibility-version=19.0 when
we detect that a VS 2015 compiler is present.  Even though we're
actually using clang to do the compilation, clang uses this same
detection algorithm to determine the location of the standard
library.  So this check is tantanmount to saying "If clang is going
to find MSVC 2015's standard library, then pass 19.0 for
-fms-compatibility-version.

Zachary Turner 48ef8d4c37 Fix some issues with swig & string conversion.
This patch fixes two issues:

1) Popen needs to be used with universal_newlines=True by default.
   This elicits automatic decoding from bytes -> string in Py3,
   and has no negative effects in other Py versions.
2) The swig typemaps for converting between string and (char*, int)
   did not work correctly when the length of the string was 0,
   indicating an error.  In this case we would try to construct a
   string from uninitialized data.
3) Ironically, the bug mentioned in #2 led to a test passing on
   Windows that was actually broken, because the test was written
   such that the assertion was never even getting checked, so it
   passed by default.  So we additionally fix this test to also
   fail if the method errors.  By fixing this test it's now broken
   on Windows, so we also xfail it.

This CL also removes a hack from Scalar::ULongLong what was most likely
added to get this test passing as it only worked in case the value of
the variable is -1 and didn't make any sense even in that case.

Abhishek Aggarwal be994649b4 Fix to solve Bug 23139 & Bug 23560
Summary:
 - Reason of both bugs:

   1. For the very first frame, Unwinder doesn't check the validity
      of Full UnwindPlan before creating StackFrame from it:

        When 'process launch' command is run after setting a breakpoint
        in inferior, the Unwinder runs and saves only Frame 0 (the frame
        in which breakpoint was set) in thread's StackFrameList i.e.
        m_curr_frames_sp. However, it doesn't check the validity of the
        Full UnwindPlan for this frame by unwinding 2 more frames further.

   2. Unwinder doesn't update the CFA value of Cursor when Full UnwindPlan
      fails and FallBack UnwindPlan succeeds in providing valid CFA values
      for frames:

        Sometimes during unwinding of stack frames, the Full UnwindPlan
        inside the RegisterContextLLDB object may fail to provide valid
        CFA values for these frames. Then the Fallback UnwindPlan is used
        to unwind the frames.

        If the Fallback UnwindPlan succeeds, then it provides a valid new
        CFA value. The RegisterContextLLDB::m_cfa field of Cursor object
        is updated during the Fallback UnwindPlan execution. However,
        UnwindLLDB misses the implementation to update the 'cfa' field
        of this Cursor with this valid new CFA value.

 - This patch fixes both these issues.

 - Remove XFAIL in test files corresponding to these 2 Bugs

how this all works with the deeply nested decorators, but the spirit
of the patch here is to do do the following: If the condition function
is true, use the original unittest2.expectedFailure decorator.  Otherwise
don't use any decorator, just call the test function.

Zachary Turner c1b7cd72db Python 3 - Turn on absolute imports, and fix existing imports.
Absolute imports were introduced in Python 2.5 as a feature
(e.g. from __future__ import absolute_import), and made default
in Python 3.

When absolute imports are enabled, the import system changes in
a couple of ways:

1) The `import foo` syntax will *only* search sys.path.  If `foo`
   isn't in sys.path, it won't be found.  Period.  Without absolute
   imports, the import system will also search the same directory
   that the importing file resides in, so that you can easily
   import from the same folder.

2) From inside a package, you can use a dot syntax to refer to higher
   levels of the current package.  For example, if you are in the
   package lldbsuite.test.utility, then ..foo refers to
   lldbsuite.test.foo.  You can use this notation with the
   `from X import Y` syntax to write intra-package references.  For
   example, using the previous locationa s a starting point, writing
   `from ..support import seven` would import lldbsuite.support.seven

Since this is now the default behavior in Python 3, this means that
importing from the same directory with `import foo` *no longer works*.
As a result, the only way to have portable code is to force absolute
imports for all versions of Python.

See PEP 0328 [https://www.python.org/dev/peps/pep-0328/] for more
information about absolute and relative imports.

Zachary Turner bbc5b46a10 Python 3 - Use universal_newlines when calling subprocess.check_output
By default in Python 3, check_output() returns a program's output as
an encoded byte sequence.  This means it returns a Py3 `bytes` object,
which cannot be compared to a string since it's a different fundamental
type.

Although it might not be correct from a purist standpoint, from a
practical one we can assume that all output is encoded in the default
locale, in which case using universal_newlines=True will decode it
according to the current locale.  Anyway, universal_newlines also
has the nice behavior that it converts \r\n to \n on Windows platforms
so this makes parsing code easier, should we need that.  So it seems
like a win/win.

Zachary Turner 19474e1801 Remove `use_lldb_suite` from the package, and don't import it anymore.
This module was originally intended to be imported by top-level
scripts to be able to find the LLDB packages and third party
libraries.  Packages themselves shouldn't need to import it,
because by the time it gets into the package, the top-level
script should have already done this.  Indeed, it was just
adding the same values to sys.path multiple times, so this
patch is essentially no functional change.

To make sure it doesn't get re-introduced, we also delete the
`use_lldb_suite` module from `lldbsuite/test`, although the

Pavel Labath 862432c90e Fix race during process detach
Summary:
The code which was preventing the usage of the OS plugin while detach is in
progress also prevented us to update the thread list correctly. This resulted
in an empty thread list, which confused the detaching logic. Change the
condition do only do what it says (disable the usage of the OS plugin).

Ravitheja Addepally 46bcbaafb5 Changes for Bug 25251
Summary:
The solution to bug 24074,rL249673 needed
to parse the function information from the Dwarf in order
to set the SymbolContext. For that, GetFunction was called
for the parent in GetTypeForDIE, which parses the
ChildParameters and in the flow, GetTypeForDIE was called
for one of the sibling die and so an infinite
loop was triggered by calling GetFunction repeatedly for the
same function.

The changes in this revision modify the GetTypeForDIE to only
resolve the function context in the Type Lookup flow and so
prevent the infinite loop.

A testcase has also been added to check for regression in the
future and a test vector had been added to the testcase of
24074.

Zachary Turner 95c453a221 Tighten up sys.path, and use absolute imports everywhere.
For convenience, we had added the folder that dotest.py was in
to sys.path, so that we could easily write things like
`import lldbutil` from anywhere and any test.  This introduces
a subtle problem when using Python's package system, because when
unittest2 imports a particular test suite, the test suite is detached
from the package.  Thus, writing "import lldbutil" from dotest imports
it as part of the package, and writing the same line from a test
does a fresh import since the importing module was not part of
the same package.

The real way to fix this is to use absolute imports everywhere.  Instead
of writing "import lldbutil", we need to write "import
lldbsuite.test.util".  This patch fixes up that and all other similar
cases, and additionally removes the script directory from sys.path
to ensure that this can't happen again.

Zachary Turner 7d564544eb Make dosep correctly invoke the top-level script when forking out
packages/Python/lldbsuite is now a Python package, and it relies
on its __init__.py being called to do package-level initialization.
If you exec packages/Python/lldbsuite/dotest.py directly, you won't
get this package level initialization, and things will fail.  But
without this patch, this is exactly what dosep itself does.  To
launch the multi-processing fork, it was hardcoding a path to
dotest.py and exec'ing it from inside the package.

The fix here is to get the path of the top-level script, and
then exec'ing that instead.  A more robust solution would involve
refactoring the code so that dosep execs some internal script that
imports lldbsuite, but that's a bit more involved.

Summary:
As per the following link, the "--" separator can appear between the options
and parameters of any MI command. Previously this separator was only
handled by the `-data-disassemble` MI command. I have moved the relevant
code into `CMICmdBase` so that any MI command can handle the
aforementioned separator.

Enrico Granata 8627209b43 Some test cases that need the lldbExec path were failing because lldbExec was turning out to be None even though it was being validly set by dotest.py
It turns out that lldbtest_config was being imported locally to "lldbsuite.test" instead of globally, so when the test cases got individually brought by a global import via __import__ by unittest2, they did not see the lldbtest_config import, and ended up importing a new separate copy of it, with lldbExec unset

This is a simple hackaround that brings lldbtest_config to global visibility and makes sure the configuration data is correctly shared

Hafiz Abid Qadeer d122fd8d06 Better handle the arguments common to all MI commands.
Summary:
I observed that eclipse was passing --thread-group for many other commands
then we are currently handling. Looking at the MI documentation, the
following link states that each MI command accept the --thread and
--frame option. Looking at the GDB implementation, it seems that apart
from these 2, --thread-group is also handled the same way.

https://sourceware.org/gdb/onlinedocs/gdb/Context-management.html#Context-management

So instead of handling those arguments in every comamnds, I have moved
them into the base class and removed them from elsewhere. Now any command
can use these arguments. The patch seems big but most of the changes are
mechanical.

This is the conclusion of an effort to get LLDB's Python code
structured into a bona-fide Python package.  This has a number
of benefits, but most notably the ability to more easily share
Python code between different but related pieces of LLDB's Python
infrastructure (for example, `scripts` can now share code with
`test`).
