working directory by default -- a typical security problem that we
need to be more conservative about.
It adds a new target setting, target.load-cwd-lldbinit which may
be true (always read $cwd/.lldbinit), false (never read $cwd/.lldbinit)
or warn (warn if there is a $cwd/.lldbinit and don't read it). The
default is set to warn. If this is met with unhappiness, we can look
at changing the default to true (to match current behavior) on a
different platform.
This does not affect reading of ~/.lldbinit - that will still be read,
as before. If you run lldb in your home directory, it will not warn
about the presence of a .lldbinit file there.
I had to add two SB API - SBHostOS::GetUserHomeDirectory and
SBFileSpec::AppendPathComponent - for the lldb driver code to be
able to get the home directory path in an OS neutral manner.
The warning text is
There is a .lldbinit file in the current directory which is not being read.
To silence this warning without sourcing in the local .lldbinit,
add the following to the lldbinit file in your home directory:
settings set target.load-cwd-lldbinit false
To allow lldb to source .lldbinit files in the current working directory,
set the value of this variable to true. Only do so if you understand and
accept the security risk.

Summary:
This does not yet give us a clean testsuite run but it does help with:
1. Actually building on linux
2. Run the testsuite with over 70% tests passing on linux.

The explicit APIs on SBValue obviously remain if one wants to be explicit in intent, or override this guess, but since __int__() has to pick one, an educated guess is definitely better than than always going to signed regardless

This change restores the Xcode build to working after Makefile support
was stripped from LLVM and clang recently.
With this change, the Xcode build now requires cmake (2.8.12.2+).
The cmake must either be on the path that Xcode sees, or it must
exist in one of the following locations:
* /usr/local/bin/cmake
* /opt/local/bin/cmake
* $HOME/bin/cmake
If the ninja build tool is present on the path, it will be used.
If not, ninja will be cloned (via git), bootstrap-built, and
used for the llvm/clang build.
LLDB now requires a minimum deployment target of OS X 10.9. Prior
to this, it was 10.8. The llvm/clang cmake build will not run
with Xcode 7.2 or Xcode 7.3 beta's compiler with the minimum
deployment target set to anything lower than 10.9. This is
related to #include <atomic>.
When llvm or clang source code does not exist in the lldb tree,
it will be cloned via git using http://llvm.org/git/{project}.git.
Previously it used SVN. If this causes any heartache, we can
make this smarter, autodetect an embedded svn and use svn instead.
(And/or use SVN if a git command is not available).
This change also fixes an lldb-mi linkage failure (needed
libncurses) as exposed by one of the LLVM libs.

SUMMARY:
Get the load address for the address given by symbol and function.
Earlier, this was done for function only, this patch does it for symbol too.
This patch also adds TestAvoidBreakpointInDelaySlot.py to test this change.

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.
llvm-svn: 258743
This needs to be able to handle bytes, strings, and bytearray objects.
In Python 2 this was easy because bytes and strings are the same thing,
but in Python 3 the 2 cases need to be handled separately. So as not
to mix raw Python C API code with PythonDataObjects code, I've also
introduced a PythonByteArray class to PythonDataObjects to make the
paradigm used here consistent.
llvm-svn: 258741
We already have char** typemaps which were near copy-pastes of
the const char** versions. This way we have only one version that
works for both.
llvm-svn: 257670
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.
llvm-svn: 257669
* lldb::tid_t was being converted incorrectly, so this is updated to use
PythonInteger instead of manual Python Native API calls.
* OSPlugin_RegisterContextData was assuming that the result of
get_register_data was a string, when in fact it is a bytes. So this
method is updated to use PythonBytes to do the work.

Summary: If six.py is simlink'd, an installation won't be able to find it unless it has access to the source tree that lldb was built from.

We were trying to be super smart and find all the supported language
bindings. This led to us scanning the directory and treating all
subdirectories as language binding directories. This makes it
hard to add unrelated code in this folder.
Besides, we only support one at the moment - Python. And when new
ones are added it will be trivial to just add their names to a list.
So this patch gets stupider about how to look for language binding
subfolders. Just put them in a list, and use the list.
llvm-svn: 254078
This script really should not be assuming every subdirectory is
a language directory for swig generation. Using a hack to get
this working for now, but this should be solved once this script
is re-written similar to how prepare_bindings was.
llvm-svn: 254037
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.
llvm-svn: 254023
This version supports local generation only. It's intentionally
stupid, and does not support any kind of dependency checking.
If you run the script, it's going to call SWIG. While this is
a slow process, we are going to combine the use of the swig bot
with checked in static bindings, meaning that it won't be terribly
important to only regenerate the bindings when the input files
have actually changed.
A side benefit of this is that the implementation is drastically
simpler.
This is all experimental at the moment, but it duplicates a lot
of the logic currently found in prepare_bindings.py. There was
not a good way to reuse some of the logic without invasive changes
on that script, and since this script is still experimental, it
makes sense to just copy them over, and if / when this becomes
more mature, we can get rid of the other ones.
llvm-svn: 254022
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.
llvm-svn: 253487
This change does not introduce static bindings. It is simply using
the pylinted cleaned up code in prepare_bindings.py.
If this breaks anyting, I'll revert immediately and figure out what
needs to be addressed. I'm looking to wrap up
the cleanup aspect of the code change (pylinted, removal of code that
implements existing python stdlib code, fixes for Xcode adoption, etc.).
llvm-svn: 253478
Added a new flag, --allow-static-binding. When specified,
if (and only if) the swig binary cannot be found, then the
LLDBWrapPython.cpp and lldb.py from the
scripts/Python/{static-binding-dir} are copied into the place where
swig would have generated them.
{static-binding-dir} defaults to static-binding, and can be
overridden with the --static-binding-dir command line argument.
The static bindings checked in are from r253424.
llvm-svn: 253448
This is only used by Xcode at the moment. It replaces the
buildSwigWrapperClasses.py and related per-script-language
scripts. It also fixes a couple bugs in those w/r/t Xcode
usage:
* the presence of the GCC_PREPROCESSOR_DEFINITIONS env var
should not be short-circuiting generation of the language
binding; rather, only if LLDB_DISABLE_PYTHON is present
within that environment variable.
* some logic around what to do when building in "non-Makefile"
mode. I've switched the handling of that to be on a
"--framework" flag - if specified, we build an OS X-style
framework; otherwise, we go with non.
Putting this up now only attached to the Xcode build so
others can look at it but not be affected by it yet.
After this, I'll tackle the finalizer, along with trying
it locally on Linux.

Python 3 has lots of new debug asserts, and some of these were
firing on PythonFile. Specifically related to handling of invalid
