2020-04-07[ScriptInterpreterPython] Remove buggy code to save/restore stdin.Davide Italiano
Discussed on lldb-dev with Pavel Labath. This doesn't work for background processes [causes Python to be stuck forever], and it's unclear whether it's needed. There's no test, also. If this turns out to be useful, it can be recommitted with a functional implementation and a test.

2020-02-21Allow customized relative PYTHONHOMEHaibo Huang
Summary: This change allows a hard coded relative PYTHONHOME setting. So that python can easily be packaged together with lldb. The change includes: 1. Extend LLDB_RELOCATABLE_PYTHON to all platforms. It defaults to ON for platforms other than Windows, to keep the behavior compatible. 2. Allows to customize LLDB_PYTHON_HOME. But still defaults to PYTHON_HOME. 3. LLDB_PYTHON_HOME can be a path relative to liblldb. If it is relative, we will resolve it before send it to Py_DecodeLocale.

2020-01-28Make llvm::StringRef to std::string conversions explicit.Benjamin Kramer
This is how it should've been and brings it more in line with std::string_view. There should be no functional change here. This is mostly mechanical from a custom clang-tidy check, with a lot of manual fixups. It uncovers a lot of minor inefficiencies. This doesn't actually modify StringRef yet, I'll do that in a follow-up.
2020-01-24[lldb][NFC] Fix all formatting errors in .cpp file headersRaphael Isemann
Summary: A *.cpp file header in LLDB (and in LLDB) should like this: ``` //===-- TestUtilities.cpp -------------------------------------------------===// ``` However in LLDB most of our source files have arbitrary changes to this format and these changes are spreading through LLDB as folks usually just use the existing source files as templates for their new files (most notably the unnecessary editor language indicator `-*- C++ -*-` is spreading and in every review someone is pointing out that this is wrong, resulting in people pointing out that this is done in the same way in other files). This patch removes most of these inconsistencies including the editor language indicators, all the different missing/additional '-' characters, files that center the file name, missing trailing `===//` (mostly caused by clang-format breaking the line).

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.

2019-10-25 Add the ability to pass extra args to a Python breakpoint callback.Jim Ingham
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.

2019-10-16update ScriptInterpreterPython to use File, not FILE*Lawrence D'Anna
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.

ScriptInterpreterPython.cpp where site-packages are added to PYTHONPATH. This change creates the path once and use it everywhere. So that they will not go out of sync.

2019-09-27remove File::SetStream(), make new files instead.Lawrence D'Anna
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.

It is also a necessary step towards https://reviews.llvm.org/D67891, and further developments for lldb_private::File.
