In commit svn r351496 I changed this condition from
`if(LLDB_CAN_USE_DEBUGSERVER)` to `if(NOT SKIP_TEST_DEBUGSERVER)`.
This causes debugserver tests to run on windows, which shouldn't happen.
SKIP_TEST_DEBUGSERVER is set either by the user (it shouldn't be set on
windows builds) or in the debugserver CMake logic (which doesn't get
included when building on windows). Therefore, I changed the condition
to be `if(LLDB_CAN_USE_DEBUGSERVER AND NOT SKIP_TEST_DEBUGSERVER)`.
llvm-svn: 351498
Summary:
The flags `LLDB_USE_SYSTEM_DEBUGSERVER` and `LLDB_NO_DEBUGSERVER` were
introduced to the debugserver build. If one of these two flags are set, then we
do not build and sign debugserver. However I noticed that we were still building
the lldbDebugserverCommon and lldbDebugserverCommon_NonUI libraries regardless
of whether or not these flags were set. I don't believe we should be building
these libraries unless we are building and signing debugserver.

When the generator supports multiple configurations, the inputs are not copied to the correct per-configuration directory. This change sets up the build to copy the inputs in each configuration directory.

We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.
Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.
Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).
Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.

Summary:
r316368 broke this build when it introduced a reference to a pthread
function to the Utility module. This caused cmake to generate an
incorrect link line (wrong order of libs) because it did not see the
dependency from Utility to the system libraries. Instead these libraries
were being manually added to each final target.
This changes moves the dependency management from the individual targets
to the lldbUtility module, which is consistent with how llvm does it.
The final targets will pick up these libraries as they will be a part of
the link interface of the module.
Technically, some of these dependencies could go into the host module,
as that's where most of the os-specific code is, but I did not try to
investigate which ones.

Patch by Jason Majors <jmajors@google.com>
llvm-svn: 304793
Summary:
This patch refactors the CMake build system's support for building debugserver to allow us to build the majority of debugserver's sources into the debugserverCommon library which can then be reused by unit tests.
The first unit test I've written tests debug server's ability to accept incoming connections from LLDB. The test forks the process, and one side creates a listening socket using debugserver's socket API, the other side creates a transmitting socket using LLDB's TCPSocket class.
I have no clue where to even start getting this connected into the LLDB Xcode project, so for now these tests are CMake-only.

of home_directory() that LLDB's own implementation had worked

We started passing the list of libraries to link to the
add_lldb_unittest macro, but that macro wasn't actually doing anything
with them. Fix that.
llvm-svn: 293913
Summary:
Problem:
There are three filelds in the ELF header - e_phnum, e_shnum, and e_shstrndx -
that could be bigger than 64K and therefore do not fit in 16 bits reserved for
them in the header. If this happens, pretty often there is a special section at
index 0 which contains their real values for these fields in the section header
in the fields sh_info, sh_size, and sh_link respectively.
Fix:
- Rename original fields in the header declaration. We want to have them around
just in case.
- Reintroduce these fields as 32-bit members at the end of the header. By default
they are initialized from the header in Parse() method.
- In Parse(), detect the situation when the header might have been extended into
section info #0 and try to read it from the same data source.
- ObjectFileELF::GetModuleSpecifications accesses some of these fields but the
original parse uses too small data source. Re-parse the header if necessary
using bigger data source.
- ProcessElfCore::CreateInstance uses header with potentially sentinel values,
but it does not access these fields, so a comment here is enough.

allow for the core engine to be exercised by unit tests.
The UnwindAssembly_x86 class will have access to Targets, Processes,
Threads, RegisterContexts -- it will be working in the full lldb
environment.
x86AssemblyInspectionEngine is layered away from all of that, it is
given some register definitions and a bag of bytes to profile.
I wrote an initial unittest for a do-nothing simple x86_64/i386
function to start with. I'll be adding more.
The x86 assembly unwinder was added to lldb early in its bringup;
I made some modernization changes as I was refactoring the code
to make it more consistent with how we write lldb today.
I also added RegisterContextMinidump_x86_64.cpp to the xcode project

The testsuite passes with this change, but there was quite a bit of

SendContinuePacketAndWaitForResponse was huge function with very complex interactions with
several other functions (SendAsyncSignal, SendInterrupt, SendPacket). This meant that making any
changes to how packet sending functions and threads interact was very difficult and error-prone.
This change does not add any functionality yet, it merely paves the way for future changes. In a
follow-up, I plan to add the ability to have multiple query packets in flight (i.e.,
request,request,response,response instead of the usual request,response sequences) and use that
to speed up qModuleInfo packet processing.
Here, I introduce two special kinds of locks: ContinueLock, which is used by the continue thread,
and Lock, which is used by everyone else. ContinueLock (atomically) sends a continue packet, and
blocks any other async threads from accessing the connection. Other threads create an instance of
the Lock object when they want to access the connection. This object, while in scope prevents the
continue from being send. Optionally, it can also interrupt the process to gain access to the
connection for async processing.
Most of the syncrhonization logic is encapsulated within these two classes. Some of it still
had to bleed over into the SendContinuePacketAndWaitForResponse, but the function is still much
more manageable than before -- partly because of most of the work is done in the ContinueLock
class, and partly because I have factored out a lot of the packet processing code separate
functions (this also makes the functionality more easily testable). Most importantly, there is
none of syncrhonization code in the async thread users -- as far as they are concerned, they just
need to declare a Lock object, and they are good to go (SendPacketAndWaitForResponse is now a
very thin wrapper around the NoLock version of the function, whereas previously it had over 100
lines of synchronization code). This will make my follow up changes there easy.
I have written a number of unit tests for the new code and I have ran the test suite on linux and
osx with no regressions.

PDB is Microsoft's debug information format, and although we
cannot yet generate it, we still must be able to consume it.
Reason for this is that debug information for system libraries
(e.g. kernel32, C Runtime Library, etc) only have debug info
in PDB format, so in order to be able to support debugging
of system code, we must support it.
Currently this code should compile on every platform, but on
non-Windows platforms the PDB plugin will return 0 capabilities,
meaning that for now PDB is only supported on Windows. This
may change in the future, but the API is designed in such a way
that this will require few (if any) changes on the LLDB side.
In the future we can just flip a switch and everything will
work.
This patch only adds support for line tables. It does not return
information about functions, types, global variables, or anything
else. This functionality will be added in a followup patch.

With this change, liblldb is 95% of the way towards being able
to work under both Python 2.x and Python 3.x. This should
introduce no functional change for Python 2.x, but for Python
3.x there are some important changes. Primarily, these are:
1) PyString doesn't exist in Python 3. Everything is a PyUnicode.
To account for this, PythonString now stores a PyBytes instead
of a PyString. In Python 2, this is equivalent to a PyUnicode,
and in Python 3, we do a conversion from PyUnicode to PyBytes
and store the PyBytes.
2) PyInt doesn't exist in Python 3. Everything is a PyLong. To
account for this, PythonInteger stores a PyLong instead of a
PyInt. In Python 2.x, this requires doing a conversion to
PyLong when creating a PythonInteger from a PyInt. In 3.x,
there is no PyInt anyway, so we can assume everything is a
PyLong.
3) PyFile_FromFile doesn't exist in Python 3. Instead there is a
PyFile_FromFd. This is not addressed in this patch because it
will require quite a large change to plumb fd's all the way
through the system into the ScriptInterpreter. This is the only
remaining piece of the puzzle to get LLDB supporting Python 3.x.
Being able to run the test suite is not addressed in this patch.
After the extension module can compile and you can enter an embedded
3.x interpreter, the test suite will be addressed in a followup.
llvm-svn: 249886
Previously embedded interpreters were handled as ad-hoc source
files compiled into source/Interpreter. This made it hard to
disable a specific interpreter, or to add support for other
interpreters and allow the developer to choose which interpreter(s)
were enabled for a particular build.
This patch converts script interpreters over to a plugin-based system.
Script interpreters now live in source/Plugins/ScriptInterpreter, and
the canonical LLDB interpreter, ScriptInterpreterPython, is moved there
as well.
Any new code interfacing with the Python C API must live in this location
from here on out. Additionally, generic code should never need to
reference or make assumptions about the presence of a specific interpreter
going forward.

Summary:
Since all TSC operations are now executed synchronously, TSC has become a little more than a
messenger between different parts of NativeProcessLinux. Therefore, the reason for its existance
has disappeared.
This commit moves the contents of the TSC into the NPL class. This will enable us to remove all
the boilerplate code in NPL (as it stands now, this is most of the class), which I plan to do in
subsequent commits.
Unfortunately, this also means we will lose the unit tests for the TSC. However, since the size
of the TSC has diminished, the unit tests were not testing much at this point anyway, so it's not
a big loss.
No functional change.

Sigh. There's really not a good alternative until we decouple
python from lldb better. The only way the build works right now
is by having every executable link against every LLDB library.
This causes implicit transitive link dependencies on the union
of everything that LLDB brings in. Which means that if all we
want is one header file from interpreter, we have to bring in
everything, including everything that everything depends on,
which means python.
There's outstanding efforts to address this, but it's not yet
