This just fetches the last package which has fetch_all_solibs and we know
it will contain the image of our test executable to get the tests running again.
This is relanding D81001. The patch originally failed as on newer editline
versions it seems CC_REFRESH will move the cursor to the start of the line via
\r and then back to the original position. On older editline versions like
the one used by default on macOS, CC_REFRESH doesn't move the cursor at all.
As the patch changed the way we handle tab completion (previously we did
REDISPLAY but now we're doing CC_REFRESH), this caused a few completion tests
to receive this unexpected cursor movement in the output stream.
This patch updates those tests to also accept output that contains the specific
cursor movement commands (\r and then \x1b[XC). lldbpexpect.py received an
utility method for generating the cursor movement escape sequence.
Original summary:
I implemented autosuggestion if there is one possible suggestion.
I set the keybinds for every character. When a character is typed, Editline::TypedCharacter is called.
Then, autosuggestion part is displayed in gray, and you can actually input by typing C-k.
Editline::Autosuggest is a function for finding completion, and it is like Editline::TabCommand now, but I will add more features to it.
Testing does not work well in my environment, so I can't confirm that it goes well, sorry. I am dealing with it now.

Some of the test methods were already skipped because of an unexpected
packet. The test started failing after it was expanded. Skip the whole
test with reproducers so we don't have to add the decorator for every
method.
expect_expr currently can't verify the children of the result SBValue.
This patch adds the ability to check them. The idea is to have a CheckValue
class where one can specify what attributes of a SBValue should be checked.
Beside the properties we already check for (summary, type, etc.) this also
has a list of children which is again just a list of CheckValue object (which
can also have children of their own).
The main motivation is to make checking the children no longer based
on error-prone substring checks that allow tests to pass just because
for example the error message contains the expected substrings by accident.
I also expect that we can just have a variant of `expect_expr` for LLDB's
expression paths (aka 'frame var') feature.

Currently, the skipIfRosetta decorator will skip tests with the message

`getCompilerVersion` assumes that `clang --version` prints out a string like `version [0-9\.]+`.
If clang is built from trunk, the version line might look like `clang version trunk (123abc)`.
Since there isn't any way of knowing by the commit id alone whether one commit is newer or older than another git commit (or clang version), assume that clang with a version id like this is very close to trunk. For example, any tests with `@skipIf(compiler="clang", compiler_version=['<', '8'])` should be run.

LLDB tests assume that tests are in the test tree (the `LLDB_TEST_SRC` env variable, configured by `dotest.py`).
If this assertion doesn't hold, tests fail in strange ways. An early place this goes wrong is in `compute_mydir` which does a simple length-based substring to get the relative path. Later, we use that path to chdir to. If the test file and test tree don't agree in realpath-ness (and therefore length), this will be a cryptic error of chdir-ing to a directory that does not exist.
The actual discrepency is that the places we look for `use_lldb_suite.py` don't use a realpath, but `dotest.py` does (see initialization of `configuration.testdirs`).
It doesn't particularly matter whether we use realpath or abspath to canonicalize things, but many places end up with implicit dependencies on the canonicalized pwd being a realpath, so make them realpath consistently. Also, in the `compute_mydir` method mentioned, raise an error if the path types don't agree.

Add an option that allows the user to decide to not make the inferior is

responsible, it inherits the permissions of its parent. The motivation
is the scenario of running the LLDB test suite from an external hard
drive. If the inferior is responsible, every test needs to be granted
access to the external volume. When the permissions are inherited,

This is a followup to 817b3a6fe3a4452eb61a2503c8beaa7267ca0351: in `builder_base` we should use abspath, not realpath, because the name is significant.
This is used by test cases that use `@skipIf(compiler="clang", compiler_version=['<', <version>])`
In these two cases, use of `os.path.realpath` is problematic:
- The name of the compiler is significant [1] . For testing purposes, we might
provide a compiler called "clang" which is actually a symlink to some build
script (which does some flag processing before invoking the real clang). The
destination the symlink may not be called "clang", but we still want it to be
treated as such.
- When using a build system that puts build artifacts in an arbitrary build
location, and later creates a symlink for it (e.g. creates a
"<lldb root>/lldbsuite/test/dotest.py" symlinks that points to
"/build/artifact/<hash>/dotest.py"), looking at the realpath will not match
the "test" convention required here.
[1] See `Makefile.rules` in the lldb tree, e.g. we use different flags if the compiler is named "clang"

Will reland after some investigation and/or after adding some extra logging to help debug the issue.
If the test suite is misconfigured when it's run (a bad regexp, wrong test directory, etc.), the test suite may not discover any tests. When this happens, the test runner exits happily because no tests failed:
```
Ran 0 tests in 0.000s
RESULT: PASSED (0 passes, 0 failures, 0 errors, 0 skipped, 0 expected failures, 0 unexpected successes)
```
Change this to return an error so the misconfiguration can be more easily detected. Verified that `lldb-dotest -p TestDoesNotExist.py` successfully fails.

After more investigation, I realised this part of the code is totally
unused. It was used for communicating the test results from the
"inferior" dotest process to the main "dosep" process running
everything. Now that everything is being orchestrated through lit, this
is not used for anything.
Summary:
registerSharedLibrariesWithTarget was setting the library path
environment variable to the process build directory, but the function is
also accepting libraries in other directories (in which case they won't
be found automatically).
This patch makes the function set the path variable correctly for these
libraries too. This enables us to remove the code for setting the path
variable in TestWeakSymbols.py, which was working only accidentally --
it was relying on the fact that
launch_info.SetEnvironmentEntries(..., append=True)
would not overwrite the path variable it has set, but that is going to
change with D83306.

Remove custom tearDownHooks from GDB Remote tests as we now cleanup

Remove the forkSubprocess method and its bookkeeping.
TestCreateAfterAttach is the only test using the fork method and I'm not
convinced it adds enough to warrant the maintenance. Pavel suggested the
same thing in D83815.
It's possible to achieve the same effect by providing multi-step recipe
instead of a single-step recipe where the step happens to contain
multiple commands.
Summary:
Currently expect_expr will not run the expression if no target is selected. This
patch changes this behavior so that expect_expr will instead fall back to the
dummy target similar to what the `expression` command is doing. This way we
don't have to compile an empty executable to be able to use `expect_expr` (which
is a waste of resources for tests that just test generic type system features).
As a test I modernized the TestTypeOfDeclTypeExpr into a Python test +
expect_expr (as it relied on the dummy target fallback of the expression
command).
