This both reverts r357277 to rebundle a version of Python's readline module based on libedit. However, this patch also provides two improvements over the previous implementation: 1. use PyMem_RawMalloc instead of PyMem_Malloc, as expected by PyOS_Readline (prevents to segfault upon exit of interactive session) 2. patch the readline module upon embedded interpreter loading, instead of patching it globally, which should prevent any side effect on other modules/packages 3. only activate the patched module if libedit is actually linked in lldb Differential Revision: https://reviews.llvm.org/D69793

Classess are callables and `GetArgInfo()` should work on them. On python 3 it already works, of course. `inspect` is good. On python 2 we have to add yet another special case.

* Add the ability to pass extra args to a Python breakpoint callback.Jim Ingham2019-10-253-19/+116
| | | | | | | | | | | | | | | | | For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no way to write a generic "stop when my caller is..." function, and then specify the caller when you add the command to a breakpoint. With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right signature) when the breakpoint is hit. Then in lldb, you can say: (lldb) break com add -F caller_is -k caller_name -v Foo More generally this will allow us to write reusable Python breakpoint commands.

* [LLDB] bugfix: command script add -f doesn't work for some callablesLawrence D'Anna2019-10-192-8/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: When users define a debugger command from python, they provide a callable object. Because the signature of the function has been extended, LLDB needs to inspect the number of parameters the callable can take. The rule it was using to decide was weird, apparently not tested, and giving wrong results for some kinds of python callables. This patch replaces the weird rule with a simple one: if the callable can take 5 arguments, it gets the 5 argument version of the signature. Otherwise it gets the old 4 argument version. It also adds tests with a bunch of different kinds of python callables with both 4 and 5 arguments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The current implementation of PythonCallable::GetNumArguments is not exception safe, has weird semantics, and is just plain incorrect for some kinds of functions. Python 3.3 introduces inspect.signature, which lets us easily query for function signatures in a sane and documented way. This patch leaves the old implementation in place for < 3.3, but uses inspect.signature for modern pythons. It also leaves the old weird semantics in place, but with FIXMEs grousing about it. We should update the callers and fix the semantics in a subsequent patch. It also adds some tests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: ScriptInterpreterPython needs to save and restore sys.stdout and friends when LLDB runs a python script. It currently does this using FILE*, which is not optimal. If whatever was in sys.stdout can not be represented as a FILE*, then it will not be restored correctly when the script is finished. It also means that if the debugger's own output stream is not representable as a file, ScriptInterpreterPython will not be able to redirect python's output correctly. This patch updates ScriptInterpreterPython to represent files with lldb_private::File, and to represent whatever the user had in sys.stdout as simply a PythonObject. This will make lldb interoperate better with other scripts or programs that need to manipulate sys.stdout.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Python APIs nearly all can return an exception. They do this by returning NULL, or -1, or some such value and setting the exception state with PyErr_Set*(). Exceptions must be handled before further python API functions are called. Failure to do so will result in asserts on debug builds of python. It will also sometimes, but not usually result in crashes of release builds. Nearly everything in PythonDataObjects.h needs to be updated to account for this.

* remove File::SetStream(), make new files instead.Lawrence D'Anna2019-09-271-13/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch removes File::SetStream() and File::SetDescriptor(), and replaces most direct uses of File with pointers to File. Instead of calling SetStream() on a file, we make a new file and replace it. My ultimate goal here is to introduce a new API class SBFile, which has full support for python io.IOStream file objects. These can redirect read() and write() to python code, so lldb::Files will need a way to dispatch those methods. Additionally it will need some form of sharing and assigning files, as a SBFile will be passed in and assigned to the main IO streams of the debugger. In my prototype patch queue, I make File itself copyable and add a secondary class FileOps to manage the sharing and dispatch. In that case SBFile was a unique_ptr<File>. (here: https://github.com/smoofra/llvm-project/tree/files) However in review, Pavel Labath suggested that it be shared_ptr instead. (here: https://reviews.llvm.org/D67793) In order for SBFile to use shared_ptr<File>, everything else should as well. If this patch is accepted, I will make SBFile use a shared_ptr I will remove FileOps from future patches and use subclasses of File instead.

This is because those parts of LLDB rely on GetStream() to use the file, and that in turn relies on calling fdopen on the descriptor. When calling fdopen, GetStream relies on m_options to determine the access mode. If m_options has never been set, GetStream() will fail.
