2019-11-04[LLDB][Python] remove ArgInfo::countLawrence D'Anna
Summary: This patch updates the last user of ArgInfo::count and deletes it. I also delete `GetNumInitArguments()` and `GetInitArgInfo()`. 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. But hey if python 2 wasn't crufty we wouln't need python 3. I also delete `is_bound_method` becuase it is unused.

Summary: It is inherently unsafe to allow a python program to manipulate borrowed memory from a python object's destructor. It would be nice to flush a borrowed file when python is finished with it, but it's not safe to do on python 2. Python 3 does not suffer from this issue.

2019-10-19[LLDB] bugfix: command script add -f doesn't work for some callablesLawrence D'Anna
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.

2019-10-17clean up the implementation of PythonCallable::GetNumArgumentsLawrence D'Anna
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.

2019-10-08exception handling in PythonDataObjects.Lawrence D'Anna
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.

2019-09-23File::SetDescriptor() should require optionsJonas Devlieghere
lvm_private::File::GetStream() can fail if m_options == 0 It's not clear from the header a File created with a descriptor will be not be usable by many parts of LLDB unless SetOptions is also called, but it is. 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. This patch adds options as a required argument to File::SetDescriptor and the corresponding constructor.

2019-04-10[NFC] Remove ASCII lines from commentsJonas Devlieghere
A lot of comments in LLDB are surrounded by an ASCII line to delimit the begging and end of the comment. Its use is not really consistent across the code base, sometimes the lines are longer, sometimes they are shorter and sometimes they are omitted. Furthermore, it looks kind of weird with the 80 column limit, where the comment actually extends past the line, but not by much. Furthermore, when /// is used for Doxygen comments, it looks particularly odd. And when // is used, it incorrectly gives the impression that it's actually a Doxygen comment. I assume these lines were added to improve distinguishing between comments and code. However, given that todays editors and IDEs do a great job at highlighting comments, I think it's worth to drop this for the sake of consistency. The alternative is fixing all the inconsistencies, which would create a lot more churn. Differential revision: https://reviews.llvm.org/D60508 llvm-svn: 358135

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.
