I don't know what the intent of parts of this test were. We set a
bunch of breakpoints and ran from one to the other, doing "self.runCmd("thread backtrace")"
then continuing to the next one. We didn't actually verify the contents of the backtrace,
nor that we hit the breakpoints we set in any particular order. The only actual test was
to run sel_getName at two of these stops.
So I reduced the test to just stopping at the places where we were actually going to run
an expression, and tested the expression.

This test is about disassembling symbols in a framework without debug information.
So we don't need to run it once per debug info flavor.

Jim pointed out that the LLDB global variables should only be available
in interactive mode. When used from a command for example, their values
might be stale or not at all what the user expects. Therefore we want to
explicitly make these variables unavailable.

This test is failing on the Fedora bot (staging). Rather than failing
with an IndexError, we should trigger an assert and dump the log when
the regex doesn't match.
llvm-svn: 372052
This ensures that if the assertion fails we dump the log content. This
should help me investigate what the output looks like on Windows, where
the test is failing.

The new centralized way of doing API logging through the reproducer
macros is lacking a way to easily correlate instances of API objects.
Logging the this pointer makes that significantly easier. For methods
this is now always passed as the first argument, similar to the self
argument in Python.
This patch also adds a test case for API logging, which uncovered that
we were not quoting strings.

After reverting the deletion of the functionalities/breakpoint tests,
we now have some tests twice in the test/ folder which breaks dotest:
* commands/breakpoint/basic
* functionalities/breakpoint/breakpoint_command
After looking over these tests, I think it makes sense to only
keep the original functionalities/ folder. The commands/breakpoint/basic
test are not exclusively testing the breakpoint command itself, so
they shouldn't be in commands/ in the first place. Note that these
folders have identical contents (beside small adjustments regarding
the Makefile which landed after the restructuring).

Summary:
This patch adds support of watchpoints to the old `ProcessWindows` plugin.
The `ProcessWindows` plugin uses the `RegisterContext` to set and reset
watchpoints. The `RegisterContext` has some interface to access watchpoints,
but it is very limited (e.g. it is impossible to retrieve the last triggered
watchpoint with it), that's why I have implemented a slightly different
interface in the `RegisterContextWindows`. Moreover, I have made the
`ProcessWindows` plugin responsible for search of a vacant watchpoint slot,
because watchpoints exist per-process (not per-thread), then we can place
the same watchpoint in the same slot in different threads. With this scheme
threads don't need to have their own watchpoint lists, and it simplifies
identifying of the last triggered watchpoint.

The bugreport command exists to create domain-specific bug reports.
Currently it has one implementation for filing bugs on the unwinder. As
far as we can tell, it has never been of use. Although not exactly the
same as the reproducers, it's a bit confusing to have two parallel
command trees for (kind of) the same thing.

I'm still unable to reproduce this locally, so let's see if this
is enough to make the bots happy. The missing dimension parameter
seems to be the biggest difference between these tests and
TestIOHandlerCompletion.py which runs just fine on the same bot,
so that's the motivation for trying this out.

This appears to be a really ancient way of running the test suite. It

Summary:
In r367234 we introduced a central place to hold the set up commands for
the various ways we have of launching lldb. However, a number of
commands still remained outside of that.
This patch moves the remaining set up commands into this function, which
allows us to remove manual clang module path setting code in
TestBatchMode.
One unfortunate victim of this approach is TestSTTYBeforeAndAfter which,
due to how it launches lldb (pexpect->expect->lldb), fails get the
quoting right. It would be possible to fix the quoting there, it would be a bit
icky, and none of the commands in this list are really relevant for what this
test is doing, so I just remove the commands outright.

The flakiness on our local machines seems to come for a race in the kernel
between task_suspend and the creation of the Mach exceptions for the threads
that hit breakpoints. The debugserver code is written with the assumption
that the kernel will be able to provide us with all the exceptions for a
given task once task_suspend returns. On machines with higher core counts,
this seems not to be the case. The first batch of exceptions we get after
task_suspend does not contain exceptions for all the threads that have hit
a breakpoint, thus they get misreprorted in the first stop packet.
Adding a 1ms timeout to the call that retrieves the batch of exceptions
seems to workaround the issue reliably on our machines, and it shoulnd't
impact standard debugging scenarios too much (a stop will incur an additional
1ms delay). We'll be talking to the kernel team to figure out the right
contract for those APIs.
This patch also reverts part of Jonas' previous workaround for the
issue (r370785).

Summary:
We got a radar that printing small floats is not very user-friendly in LLDB as we print them with up to
100 leading zeroes before starting to use scientific notation. This patch changes this by already using
scientific notation when we hit 6 padding zeroes by default and moves this value into a target setting
so that users can just set this number back to 100 if they for some reason preferred the old behaviour.
This new setting is influencing how we format data, so that's why we have to reset the data visualisation
cache when it is changed.
Note that we have always been using scientific notation for large numbers because it seems that
the LLVM implementation doesn't support printing out the padding zeroes for them. I would have fixed
that if it was trivial, but looking at the LLVM implementation for this it seems that this is not as trivial
as it sounds. I would say we look into this if we ever get a bug report about someone wanting to have
a large amount of trailing zeroes in their numbers instead of using scientific notation.

Instead of each test case knowing its depth relative to the test root,
we can just have dotest add the folder containing Makefile.rules to the

This was motivated by r370616, though I have been wanting to do this
ever since we moved to building tests out-of-tree.

On "fast" macOS machines, the TestConcurrentMany*.py tests would fail
randomly with different numbers of breakpoints, watchpoints, etc. This

structural fix but it reduces the flakiness.
