Summary:
This change fixes one issue with `lldb.command`, and also reduces the implementation.
The fix: a command function's docstring was not shown when running `help <command_name>`. This is because the docstring attached the source function is not propagated to the decorated function (`f.__call__`). By returning the original function, the docstring will be properly displayed by `help`.
Also with this change, the command name is assumed to be the function's name, but can still be explicitly defined as previously.
Additionally, the implementation was updated to:
* Remove inner class
* Remove use of `inspect` module
* Remove `*args` and `**kwargs`

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.

When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.
This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally
disabled or deleted.

You can get a breakpoint to auto-continue by adding "continue"
as a command, but that has the disadvantage that if you hit two
breakpoints simultaneously, the continue will force the process
to continue, and maybe even forstalling the commands on the other.

whether to stop.
Writing tests, I wanted to supply some commands when I made the
breakpoints, so I also added that ability.

When an option was set at on a location, I was just copying the whole option set
to the location, and letting it shadow the breakpoint options. That was wrong since

Summary:
This patch introduces new SB APIs for tracing support
inside LLDB. The idea is to gather trace data from
LLDB and provide it through this APIs to external
tools integrating with LLDB. These tools will be
responsible for interpreting and presenting the
trace data to their users.
The patch implements the following new SB APIs ->
-> StartTrace - starts tracing with given parameters
-> StopTrace - stops tracing.
-> GetTraceData - read the trace data .
-> GetMetaData - read the meta data assosciated with the trace.
-> GetTraceConfig - read the trace configuration
Tracing is associated with a user_id that is returned
by the StartTrace API and this id needs to be used
for accessing the trace data and also Stopping
the trace. The user_id itself may map to tracing
the complete process or just an individual thread.
The APIs require an additional thread parameter
when the user of these APIs wishes to perform
thread specific manipulations on the tracing instances.
The patch also includes the corresponding
python wrappers for the C++ based APIs.

We currently display a list of all minimal cycles, but it's
useful to be able to see the big picture impact of these cycles
by merging them all together into groups of interconnected
components.
Because the cycle discovery algorithm only considers "minimal"
cycles, it discards all information for dependencies which are
not considered part of the minimal cycle. So all we know is that
the components of each island definitely all depend on each other
but it's still possible that there are hidden dependencies due
to transitive includes.
The cycle list should still be the authoritative reference for
deciding where the easiest places to break cycles are, though.

This analyzes the dependency graph and computes all minimal
cycles. Equivalent cycles that differ only by rotation are
excluded, as are cycles that are "super-cycles" of other
smaller cycles. For example, if we discover the cycle
A -> C -> A, and then later A -> B -> C -> D -> A, this latter
cycle is not considered. Thus, it is possible that after
eliminating some cycles, new ones will appear. However,
this is the only way to make the algorithm terminate in
a reasonable amount of time.

A combination of broken escaping in CMake and in the python swig
generation scripts meant that the swig generation step would fail
whenever there were spaces or special characters in parameters passed to
swig.
The fix for this in CMakeLists is to use the VERBATIM option on all
COMMAND-based custom builders relying on CMake to properly escape each
argument in the generated file.
Within the python swig scripts, the fix is to call subprocess.Popen with
a list of raw argument strings rather than ones that are incorrectly
manually escaped, then passed to a shell subprocess via
subprocess.Popen(' '.join(params)). This also prevents nasty things
happening such as accidental command-injection.
This allows us to have the swig / python executables in paths containing
special chars and spaces, (or on shared storage on Win32, e.g

This change introduces optional marking of the column within a source
line where a thread is stopped. This marking will show up when the
source code for a thread stop is displayed, when the debug info
knows the column information, and if the optional column marking is
enabled.
There are two separate methods for handling the marking of the stop
column:
* via ANSI terminal codes, which are added inline to the source line
display. The default ANSI mark-up is to underline the column.
* via a pure text-based caret that is added in the appropriate column
in a newly-inserted blank line underneath the source line in
question.
There are some new options that control how this all works.
* settings set stop-show-column
This takes one of 4 values:
* ansi-or-caret: use the ANSI terminal code mechanism if LLDB
is running with color enabled; if not, use the caret-based,
pure text method (see the "caret" mode below).
* ansi: only use the ANSI terminal code mechanism to highlight
the stop line. If LLDB is running with color disabled, no
stop column marking will occur.
* caret: only use the pure text caret method, which introduces
a newly-inserted line underneath the current line, where
the only character in the new line is a caret that highlights
the stop column in question.
* none: no stop column marking will be attempted.
* settings set stop-show-column-ansi-prefix
This is a text format that indicates the ANSI formatting
code to insert into the stream immediately preceding the
column where the stop column character will be marked up.
It defaults to ${ansi.underline}; however, it can contain
any valid LLDB format codes, e.g.
${ansi.fg.red}${ansi.bold}${ansi.underline}
* settings set stop-show-column-ansi-suffix
This is the text format that specifies the ANSI terminal
codes to end the markup that was started with the prefix
described above. It defaults to: ${ansi.normal}. This
should be sufficient for the common cases.

*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.

http://lab.llvm.org:8080/green/job/lldb_build_test/20014/console,
because we’re trying to link against all .a files found in the
llvm-build/lib directory. Let’s be more specific in what we link
against. This patch applies a regexp to only use “libclang.*”,
“libLLVM.*” and not “libclang_rt.*” static archives.

Summary:
This patch fills in the implementation of GetMemoryRegions() on the Linux and Mac OS core file implementations of lldb_private::Process (ProcessElfCore::GetMemoryRegions and ProcessMachCore::GetMemoryRegions.) The GetMemoryRegions API was added under: http://reviews.llvm.org/D20565
The patch re-uses the m_core_range_infos list that was recently added to implement GetMemoryRegionInfo in both ProcessElfCore and ProcessMachCore to ensure the returned regions match the regions returned by Process::GetMemoryRegionInfo(addr_t load_addr, MemoryRegionInfo ®ion_info).

- if a synthetic child comes from the same hierarchy as its parent object, then it can't be cached by SharedPointer inside the synthetic provider, or it will cause a reference loop;
- but, if a synthetic child is made from whole cloth (e.g. from an expression, a memory region, ...), then it better be cached by SharedPointer, or it will be cleared out and cause an assert() to fail if used at a later point
For most cases of self-rooted synthetic children, we have a flag we set "IsSyntheticChildrenGenerated", but we were not using it to track caching. So, what ended up happening is each provider would set up its own cache, and if it got it wrong, a hard to diagnose crash would ensue
This patch fixes that by centralizing caching in ValueObjectSynthetic - if a provider returns a self-rooted child (as per the flag), then it gets cached centrally by the ValueObject itself
This cache is used only for lifetime management and not later retrieval of child values - a different cache handles that (because we might have a mix of self-rooted and properly nested child values for the same parent, we can't trivially use this lifetime cache for retrieval)
Fixes rdar://26480007

b) teaches PythonCallable to discover whether a callable method is bound

This code was getting evaluated unintentionally at binding
generation time instead of binding file compilation time.

https://bugs.swift.org/browse/SR-1192
llvm-svn: 265829
Summary:
This fixes a leak introduced by some of these changes:
r257644
r250530
r250525
The changes made in these patches result in leaking the FILE* passed
to SetImmediateOutputFile. GetStream() will dup() the fd held by the
python caller and create a new FILE*. It will then pass this FILE*
to SetImmediateOutputFile, which always uses the flag
transfer_ownership=false when it creates a File from the FILE*.
Since transfer_ownership is false, the lldb File destructor will not
close the underlying FILE*. Because this FILE* came from a dup-ed fd,
it will also not be closed when the python caller closes its file.
Leaking the FILE* causes issues if the same file is used multiple times
by different python callers during the same lldb run, even if these
callers open and close the python file properly, as you can end up
with issues due to multiple buffered writes to the same file.

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.

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.

We are using hardlinks instead of symlinks, and we attempted to
have some logic where we don't re-create the link if the target
file already exists. This logic is faulty, however, when you
manually delete the source file (e.g. liblldb.dll) and then rebuild
lldb so that a brand new liblldb.dll gets written. Now the two files
have different inodes, but the target exists, so we would not remake
the link and the target would become stale.
We fix this by only doing the optimization if they are really the
exact same file (by comparing inode numbers), and if they are not
the same file but the target exists, we delete it and re-create
the link.

The swig typemaps had some magic for output File *'s on OS X that made:
SBDebugger.GetOutputFileHandle()
actually work. That was protected by a "#ifdef __MACOSX__", but the corresponding define
got lost going from the Darwin shell scripts to the python scripts for running
swig, so the code was elided. I need to pass the define to SWIG, but only when
targetting Darwin.
So I added a target-platform argument to prepare_bindings, and if that
is Darwin, I pass -D__APPLE__ to swig, and that activates this code again, and
GetOutputFileHandle works again. Note, I only pass that argument for the Xcode
build. I'm sure it is possible to do that for cmake, but my cmake-foo is weak.
I should have been able to write a test for this by creating a debugger, setting the
output file handle to something file, writing to it, getting the output file handle
and reading it. But SetOutputFileHandle doesn't seem to work from Python, so I'd
have to write a pexpect test to test this, which I'd rather not do.
llvm-svn: 263183
That way you can set offset breakpoints that will move as the function they are
contained in moves (which address breakpoints can't do...)
I don't align the new address to instruction boundaries yet, so you have to get
this right yourself for now.

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.

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.

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.

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.

This finishes the effort to port python-wrapper.swig code over to
using PythonDataObjects.
Also included in this patch is the removal of `PyCallable` from
`python-wrapper.swig`, as it is no longer used after having been
replaced by `PythonCallable` everywhere.
There might be additional cleanup as followup patches, but it should
be all fairly simple and minor.
llvm-svn: 252939
PyCallable is a class that exists solely within the swig wrapper
code. PythonCallable is a more generic implementation of the same
idea that can be used by any Python-related interop code, and lives
in PythonDataObjects.h
The CL is mostly mechanical, and it doesn't cover every possible
user of PyCallable, because I want to minimize the impact of this
change (as well as making it easier to figure out what went wrong
in case this causes a failure). I plan to finish up the rest of
the changes in a subsequent patch, culminating in the removal of
PyCallable entirely.

This had been relegated to a simple forwarding function, so just
delete it in preparation of migrating all of these functions out

code can be pretty hairy, I plan to do this incrementally over a

Relying on manual Python C API calls is error prone, especially
when trying to maintain compatibility with Python 2 and Python 3.
This patch additionally fixes what appears to be a potentially
serious memory leak, in that were were incref'ing two values
returned from the session dictionary but never decref'ing them.
There was a comment indicating that it was intentional, but the
reasoning was, I believe, faulty and it resulted in a legitimate
memory leak.
Switching everything to PythonObject based classes solves both
the compatibility issues as well as the resource leak issues.

Python has a complicated mechanism of checking an objects truthity.
This involves a number of steps, which end with calling two private
methods on an object (if they are implemented). In Python 2 these
two methods are `__nonzero__` and `__len__`, and in Python 3 they
are `__bool__` and `__len__`. Because we *also* define a __len__
method for certain iterable types, this was triggering a situation
in Python 3 where `__nonzero__` wasn't defined, so it was calling
`__len__`, which was returning 0 (for example an SBDebugger with
no targets), and as a result the truthosity was determined to be
False.
We fix this by correctly using ` __bool__` for Python 3, and leave
the behavior under Python 2 unchanged.
Note that this fix is only implemented in the SWIG generation
python script, and not the SWIG generation shell script. Someone
more familiar than me with shell scripts will need to fix them
to support this for Python 3 if desired.

This reverts commit e59c95ca936f5a0a8abb987b8605fd8bf82b03b6.
This was a mistake on my part. The real problem was with my
environment. I was using a release interpreter to try to load
my debug extension module. I noticed this after I finally managed
to get into my extension module's init method, and then it segfaulted
with heap errors due to mismatched CRT (debug vs. release)
llvm-svn: 252030
In Python 2, a debug extension module required an _d suffix, so
for example the extension module `_lldb` would be backed by the file
`_lldb_d.pyd` if built in debug mode, and `_lldb.pyd` if built in
release mode. In Python 2, although undocumented, this seems to
no longer be the case, and even for a debug extension module, the
interpreter will only look for the `_lldb.pyd` name.

This has apparently been broken since June, but only on non-Windows.
Perhaps nobody noticed it because if the symlink is already there
it won't try to re-create it, and nobody ever tried doing a clean
build.
In any case, I will let the original author attempt to fix this if
he is still interested. the problem is that in the normal case
of not setting BUILD_SHARED_LIBS and simply running ninja, it would
link _lldb.so to a non-existent location, creating a dangling
symlink.
llvm-svn: 251840
Summary:
Along with this, support for an optional argument to the "num_children"
method of a Python synthetic child provider has also been added. These have
been added with the following use case in mind:
Synthetic child providers currently have a method "has_children" and
"num_children". While the former is good enough to know if there are
children, it does not give any insight into how many children there are.
Though the latter serves this purpose, calculating the number for children
of a data structure could be an O(N) operation if the data structure has N
children. The new method added in this change provide a middle ground.
One can call GetNumChildren(K) to know if a child exists at an index K
which can be as large as the callers tolerance can be. If the caller wants
to know about children beyond K, it can make an other call with 2K. If the
synthetic child provider maintains state about it counting till K
previosly, then the next call is only an O(K) operation. Infact, all
calls made progressively with steps of K will be O(K) operations.
