Summary:
These two functions are currently not correctly implemented when compared to the documented behavior.

1. These functions aren't guaranteed to return correct information until you've called X509_check_purpose on the certificate. Before then, these flag fields are uninitialized.
2. X509_get_key_usage should return UINT32_MAX when the key usage flag isn't present.

This fixes both of these issues

Summary:
The libraries in thrift/lib/py support both Python 2 and Python 3, and rely on
the Python six module for some of this compatibility support.

Update the getdeps manifest for fbthrift to indicate this dependency, and
update fbthrift's CMakeLists.txt file to find and reference python-six
properly.  This will ensure that the python-six code is built into any python
executable that uses the thrift/lib/py libraries.

Summary:
Add a new builder that can extract Python wheel files, and re-package them
for consumption by our add_fb_python_library() and add_fb_python_executable()
CMake functions.  This is useful for dependencies on packages from PyPI.

At the moment this code only handles architecture-independent pure-Python
packages.  It shouldn't be too hard to extend this to handle more complex
wheels, but for now I only need to use it for some pure-Python wheels and so I
haven't tested with more complex wheel files.

This also includes two new manifests for python-six and python-toml that take
use this new builder.

depends on the thrift compiler itself.

Previously the C++ rule indicated that the output depended on the thrift
template files, which caught most cases when the thrift compiler was updated,
but wasn't fully correct.  The thrift templates were also removed and baked
into the thrift compiler binary in D16356056.

Summary:
This commit adds a getdeps command that is able to generate
a workflow file for the GitHub Actions CI environment.

The workflow file could be expressed more simply using the matrix
syntax and with three steps (checkout, build, test), but I chose to
break out the steps for each of the dependencies because the UX
while waiting on the build is much nicer that way: the steps show
during and live log tailing for the section of the build that is
underway.  If they were all lumped into a single build step then
the logs from the boost section of the build dominate and make
the github UI work very hard.

Summary:
GitHub Actions CI `windows-latest` environment has only VS 2019
installed, so we need to expand our logic to be able to locate it.

Note that Boost 1.69 doesn't know how to locate VS 2019 so we are effectively
tied to VS 2017 at the moment; the search order in this diff reflects that.

(That means that we can't target `windows-latest` on GitHub Actions, but that
is really a concern for a later diff in this stack)

Summary:
while testing https://github.com/facebook/watchman/pull/743 I
noticed that the cmake builds were picking up the installed mingw GCC
compiler rather than the MSVC compiler.  That would be fine except that
boost is built with MSVC and its generated libraries cannot be subsequently
found by a cmake gcc build that uses FindBoost.

This commit forces cmake to pick cl.exe rather than gcc.  This is probably
fine to do unconditionally on windows, but since I've only observed this
particular problem with GitHub Actions I'm keeping it constrained to that
environment for now.

Summary:
We've been squeaking by with assuming that flex is installed already
on posix systems, but that isn't the case on the github actions default
configuration.

Adjust the bison recipe: on windows it deploys both flex and bison.  We use the
same source for both flex and bison but install flex to a separate install
prefix to make it easier to consume the flex dependency distinct from the bison
dependency.

The latest flex release segfaults during compilation on linux unless we
force -DGNU_SOURCE, so the manifest does that on linux.

Summary:
On Windows we have to explicitly invoke `make_fbpy_archive.py` with python.
Therefore use CMake's built-in `FindPythonInterp` module to find the python
executable and use that when invoking `make_fbpy_archive.py`

This is slightly complicated by the effort required to find python with older
versions of CMake.  We ideally still want to support versions of CMake back to
at least 3.8, which means we need to still support finding Python with the
older `FindPythonInterp.cmake` module

Summary:
Basic idea is to find the subprogram for a given stack trace address, scan the inlined subroutines of that subprogram recursively for all inline function calls, then find the name and location of these inline function calls.

Now only pure inline functions are supported, and class inline functions are not. Class inline functions needs a lookup path "caller->obj->type", then lookup types in .debug_types, which is more complex.

The debug info parser idea was stolen from hphp/tools/debug-parser/dwarfstate.h

Not sure if we want to add a flag to enable this feature. We can discuss over review.
