These are some minor things that I've run into on Windows, largely in
error handling paths:
* Giving --lldb-executable on Windows triggers a "useless option" code
path, which touches an attribute that only exists in the
list_debuggers tool. Switch this to use hasattr, which will work in
all subtools.
* We were over-decoding some text reporting errors, but only in an
exception path
* The path to lldb on Windows needs to be quoted (even though dexter
isn't making use of it).
Differential Revision: https://reviews.llvm.org/D74546
This reverts commit cb935f3456.
Discussion in D68708 advises that green dragon is being briskly
refurbished, and it's good to have this patch up testing it.
Dexter (Debug Experience Tester) is a test-driver for our debug info
integration tests, reading a set of debug experience expectations and
comparing them with the actual behaviour of a program under a debugger.
More about Dexter can be found in the RFC:
http://lists.llvm.org/pipermail/llvm-dev/2019-October/135773.html
and the phab review in D68708. Not all the debuginfo tests have been
transformed into Dexter tests, and we look forwards to doing that
incrementally.
This commit mostly aims to flush out buildbots that are running
debuginfo-tests but don't have python 3 installed, possibly
green-dragon and some windows bots.
