Summary:
My understanding is that this was added to make dotest interact well
with the GreenDragon bots, back when dotest was the main test driver.
Now that everything goes through lit (which has its own xunit
formatter), it seems largely irrelevant.
There are more cleanups that can be done after removing this be done
here, but this should be enough to test the waters.

Even non-remote targets may need to set the launch environment
((DY)LD_LIBRARY_PATH, specifically) to run successfully.
Also, add an assertion to better detect the case when launching a target
fails and the breakpoint is never hit.
Summary:
A lot of our tests do 'self.assertTrue(error.Success()'. The problem
with that is that when this fails, it produces a completely useless
error message (False is not True) and the most important piece of
information -- the actual error message -- is completely hidden.
Sometimes we mitigate that by including the error message in the "msg"
argument, but this has two additional problems:
- as the msg argument is evaluated unconditionally, one needs to be
careful to not trigger an exception when the operation was actually
successful.
- it requires more typing, which means we often don't do it
assertSuccess solves these problems by taking the entire SBError object
as an argument. If the operation was unsuccessful, it can format a
reasonable error message itself. The function still accepts a "msg"
argument, which can include any additional context, but this context now
does not need to include the error message.
To demonstrate usage, I replace a number of existing assertTrue
assertions with the new function. As this process is not easily
automatable, I have just manually updated a representative sample. In
some cases, I did not update the code to use assertSuccess, but I went
for even higher-level assertion apis (runCmd, expect_expr), as these are
even shorter, and can produce even better failure messages.

Summary:
This redoes https://reviews.llvm.org/D79726 and fixes two things.
- The logic that determines whether to automatically disconnect during the tear down is not very dumb compared to the original implementation. Each test will determine whether to do that or not.
- The terminate commands and terminate event were being sent after the disconnect response was sent to the IDE. That was not good, as VSCode stops the debug session as soon as it receives a disconnect response. Now, the terminate event and terminateEvents are being executed before the disconnect response is sent. This ensures that any connection between the IDE and lldb-vscode is alive while the terminate commands are executed. Besides, it also allows displaying the output of the terminate commands on the debug console, as it's still alive.

Summary:
Recently I've noticed that VSCode sometimes doesn't send the terminateDebuggee flag within the disconnectRequest,
even though lldb-vscode sets the terminateDebuggee capability correctly.
This has been causing that inferiors don't die after the debug session ends, and many users have reported issues because of this.
An easy way to mitigate this is to set better default values for the terminateDebuggee field in the disconnect request.
I'm assuming that for a launch request, the default will be true, and for attach it'll be false.

These tests are flaky on the reproducer bot. I suspect it has something
to do with the module cache. Skipping the whole category while I
investigate the issue.
This makes it possible to conditionally override some of these flags via
CFLAGS_EXTRAS. It should be NFC right now, but this seems the logical
order in which to apply these things, and I am going to make use of this
in another patch.
The different tools constructing dotest invocations (lit and
lldb-dotest) already print the command invocation so there's no need to
print it again in the dotest output.
My motivation for removing it is that it doesn't include the Python
interpreter and every time I accidentally copy it, the command fails
with an `ImportError`.

The Darwin builder is passing some of the make arguments trough the
environment instead of the command line. Update the dsym builder to do
the same as the other variants.
Don't use the environment to pass values to the builder that are present
in the dotest configuration module. A subsequent patch will pass the
remaining values through the configuration instead of the environment.
This reverts commit fd0ab3b3eb88de3fe4792c34b50084595e22d68d.
The fix here is incorrect and the actual fault was an incorrect test Makefile.
To give some more background:
The original test for D80798 compiled three source files into either one
executable or one executable + 2 shared libraries, each being one different
test setup. If both the monolithic executable and the shared libraries
where compiled in the same directory, then Make would overwrite the .o files
of one test setup with the other. This caused that while -fPIC was passed
correctly to the test setup with the shared libraries, the compiler invocations
for the monolithic executable would later overwrite these object files (and
as only the test setup with the shared library used -fPIC, it appeared as if
the shared library object files didn't receive the -fPIC flag).
Thanks to Pavel for figuring this out.
Summary:
It seems that when we rewrite a few rules to only build a dylib (i.e., when DYLIB_ONLY is set),
the rule for setting the CFLAGS for the dylib's object file compilation will no longer work. From what I can
see this is because in DYLIB_ONLY mode we pretend to compile the main executable so
the DYLIB_OBJECTS scope is actually never used.
This patch makes `-fPIC` unstopped if DYLIB_ONLY is set so that -fPIC actually ends up in the
CFLAGS for the dylib object file compilation.
The test for this is D80798 which only compiles on Linux with this patch.

Summary:
This patch adds two new arguments to the MakeInlineTest function. The
main motivation is a follow-up patch I'm preparing, but they seem
generally useful.
The first argument allows the user to specify the "build dictionary".
With this argument one can avoid the need to provide a custom Makefile
if all he needs is to override a couple of make variables. This hooks in
neatly into the existing dictionary support for non-inline tests.
The second argument specifies the name of the test. This could be used
to provide better names to the generated test classes, but it's mainly
useful in conjuction with the first argument: now that we can specify a
custom build dictionary, it may sometimes make sense to run the same
test twice with different build configurations. To achieve that, we need
to give the two tests different names, and this argument achieves that.
The usage of the arguments is demonstrated via TestBasicEntryValues.py.

Summary:
It turns out that the order in which we provide completions for expressions is
nondeterministic. This leads to confusing user experience and also breaks the
reproducer tests (as two LLDB tests can go out of sync due to the
non-determinism in the completion lists)
The reason for the non-determinism is that the CompletionConsumer informs us
about decls in the order in which it finds declarations in the lookup store of
the DeclContexts it visits (mainly this snippet in SemaLookup.cpp):
``` lang=c++
// Enumerate all of the results in this context.
for (DeclContextLookupResult R :
Load ? Ctx->lookups()
: Ctx->noload_lookups(/*PreserveInternalState=*/false)) {
[...]
```
This storage of the lookup is sorted by pointer values (see the hash of
`DeclarationName`) and can therefore be non-deterministic. The LLDB code
completion consumer that receives these calls originally expected that the order
of declarations is defined by Clang, but it seems the API expects the client to
provide an order to the completions.
This patch fixes the issue as follows:
* We sort the completions we get from Clang alphabetically and also by the
priority value we get from Clang (with priority value sorting having precedence
over the alphabetical sorting)
* We make all the functions/variables that touch a completion before the sorting
const-qualified. The idea is that this should prevent that we never have
observable side-effect from touching these declarations in a non-deterministic
order (e.g., we don't try to complete the type by accident).
This way we behave like the other parts of Clang which also sort the results by
some deterministic value (usually the name or something computed from a name,
e.g., edit distance to a given string).
We most likely also need to fix the Clang code to make the loop I listed above
deterministic to prevent these issues in the future (tracked in rdar://63442513
). This wouldn't replace the functionality provided in this patch though as we
would still need the priority and overall alphabetical sorting.
Note: I had to increase the lldb-vscode completion limit to 100 as the tests
look for strings that aren't in the first 50 results anymore due to variable
names starting with letters like 'v' (which are now always shown much further
down in the list due to the alphabetical sorting).

Skip tests or parts thereof that aren't expected to work when run from a
reproducer. Also improve the doc comments in configuration.py to prevent
mistakes in the future.
The reproducers' working directory is set to the current working
directory when they are initialized. While this is not optimal, as the
cwd can change during a debug session, it has been sufficient so far.
The current approach doesn't work for the API test suite however because
dotest temporarily changes the directory to where the test's Python file
lives.
This patch adds an API to tell the reproducers what to set the CWD to.
This is a NO-OP in every mode but capture.

Summary:
The test machinery translates each continuous block of "//%" comments
into a single breakpoint. If there's no code between the blocks the
breakpoints will end up at the same location in the program. When the
process stops at a breakpoint lldb correctly reports all breakpoint IDs,
but the test machinery only looks at the first one. This results in a
very dangerous situation as it means some checks can be silently
stopped.
This patch fixes that by making the test machinery iterate through all
breakpoints at a given location and execute all commands.

during replay. Exclude it form the substring check during replay.
Depends on D79646 to pass with reproducer replay.
Summary:
Currently loading core files on lldb-vscode is broken because there's a check in the attach workflow that asserts that the PID is valid, which of course fails for this case.
Hence, I'm adding a "coreFile" argument for the attach request, which does the work correctly.
I don't know how to test it effectively so that it runs on the buildbots and the debugger can in fact makes sense of it. Anyway, the change has been relatively simple.
