Paths on Windows are not case-sensitive. Because of this, if a file
is called main.cpp, you should be able to set a breakpoint on it
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.

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.

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

expectedFailureWindows is equivalent to using the general

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

Previously we were returning a tuple of (bool, skip_reason) from

since a value of True for the first argument implies that the

with this patch we simply return the skip reason or None directly.

This should be no functional change, just a refactoring of the

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
also does any conversion necessary to convert the output back into the
native `string` type of the running python version.

lldbinline tests previously did not run correctly unless there was already a
Makefile for them. This was because the syntax of the emitted Makefile made the

llvm-svn: 258763
Previously we were writing in the default encoding, which depends
on the operating system and is not guaranteed to be unicode aware.
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.
llvm-svn: 258759
In Python 3, whitespace inconsistences are errors. This synthetic

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.

Python 3.5 is picky about writing strings to binary files, so we now open the

The Windows 10 loader spawns threads at startup, so

Unfortunately, this turns out not to be working on the lldb-server tests, as there the server is

llvm-svn: 258501
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.

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.

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.

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.

We've now seen the rerun test phase hang in a few

Summary:
This adds ability to mark test that do not complete due to hangs, crashes, etc., as "expected",
to avoid flagging the build red for a known problem. Functionally, this extends the scope of the

start replacing the magic list of failing tests in dosep.py with our regular annotations which

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).
Hopefully this gets us more info and also handles the completely

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.
llvm-svn: 255543
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.

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().
}
}

This will be used in a future change to support rerunning flakey tests

This is implemented as an additive-style event rather than being

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.

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.

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.

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.

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
server, send the input to the server, and wait for the server to
send a response (in this case the response is just echoed back to
the client).
This gets the network communication in place, and in a subsequent
patch I will follow up with the code that actually runs swig on
the server and sends back the output instead of echoing back the
input.

-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.

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.

Summary: The self.getArchitecture() returns the architecture based on the value of -A flag passed to dotest.py script.
There are many possible values for MIPS to this option (like mips32r2, mips32r6, mips64, mips64r2,.... ).
This patch uses re.match(mips,arch) to check if architecture string starts with mips.

Change Test-rdar-12481949.py to expect GetValueAsUnsigned() to return
0xffffffff if the variable is an int32_t (signed, 4 byte integer) with
value of -1. The previous expectation where we expected the value to be
0xffffffffffffffff doesn't make sense as nothing explains why we would
treat it as an 8 byte value.
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.

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

`sets.Set` has been deprecated in favor of `set` since 2.6, and
`string.maketrans` has to be special cased. In Python 3 there

We tried implementing something akin to a conditionalExpectedFailure
decorator for unittest2. We did this by making use of some
implementation details of the unittest2 module. In an effort to make
this work with unittest, this patch removes the reliance on the
implementation details. I have a hard time wrapping my head around
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.

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.

This follows the spirit of a previous patch which did essentially
the same thing. In Python 3, when you use Popen.communicate(),
you get back a bytes object which cannot normally be treated as
a string. We could decode this manually, but universal_newlines=True
does this automatically, and there's no disadvantage to doing so
even on Python 2. So just enable it always.

Python 3 introduces the `timeout` keyword argument on Popen.wait().
If our patched version doesn't support keyword arguments, then when
the internal Python implementation attempts to call wait() with the

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.

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
original copy still remains in `lldb/test`

The `commands` module was deprecated in 2.7 and removed in 3.x.
As a workaround, we introduce a new module `seven` in

functionality for cases where it is not available.

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.

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.

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.

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
