I changed the test so I could tell whether the problem was sometimes the
interrupt was failing, or maybe the was just racy. It failed again, but
in the new failures we waited 20 seconds for the attach-wait to get interrupted
and that never happened.
So there seems to be some real raciness in the feature of interrupting an
attach-wait, but only on Linux & Windows. The bug fix that this test was
testing was for a bug that would cause us to never try to interrupt in this
case. So it looks like this test is uncovering some flakiness in the underlying
interrupt support when in this state. That's a separate bug that needs fixing.
For now, I disabled the test except on macOS where it seems to run reliably.
command.
We were reading the command output right after sending the interrupt, but
sometimes that wasn't long enough for the command result text to have been emitted.
I added a poll for the state change to eStateExited, and then added a bit more sleep
to give the command a chance to complete.
The problem is that the when the "attach" command is initiated, the
ExecutionContext for the command has a process - it's the exited one
from the previour run. But the `attach wait` creates a new process for
the attach, and then errors out instead of interrupting when it finds
that its process and the one in the command's ExecutionContext don't
match.
This change checks that if we're returning a target from
GetExecutionContext, we fill the context with it's current process, not
some historical one.
This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).
If you end up having problems merging this commit because you have made
changes to a python file, the best way to handle that is to run `git
checkout --ours <yourfile>` and then reformat it with black.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

These tests fail every 10 or so runs on Windows causing both local failures as well as buildbot failures.

The issue here was that we were not updating the interpreter's
execution context when calling HandleCommand to continue the process.
Since we had just created the process, it wasn't in the interpreter's
execution context so HandleCommand failed at CheckRequirements. The
patch fixes that by passing the process execution context directly
to HandleCommand.

This test is flakey on Windows and on failure it hangs causing the test suite to fail and future builds (on the buildbot, especially) to fail because they cannot re-write the files that are currently in use
Fix the POSIX-DYLD plugin to update the cached executable path after
attaching. Previously, the path was cached in DYLDRendezvous
constructor and not updated afterwards. This meant that if LLDB was
attaching to a process (e.g. via connecting to lldb-server), the code
stored the empty path before DidAttach() resolved it. The fix updates
the cached path in DidAttach().

Copy the recent improvements from the FreeBSDRemote plugin, notably:
- moving event reporting setup into SetupTrace() helper
- adding more debug info into SIGTRAP handling
- handling user-generated (and unknown) SIGTRAP events
- adding missing error handling to the generic signal handler
- fixing attaching to processes
- switching watchpoint helpers to use llvm::Error
- minor style and formatting changes
This fixes a number of tests, mostly related to fixed attaching.

Always clean up subprocesses on tear down instead of relying on the
caller to do so. This is not only less error prone but also means the
tests can be more concise.

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.
Add the skipIfReproducer decorator to the remaining tests that fail to
replay because the GDB remote packets diverge during replay. This is
*not* expected and should be fixed, but figuring out exactly what caused
the divergence has proven pretty difficult to track down.
I've marked these tests as skipped for now so we can get clean results
and detect new regressions. I have no evidence to believe that these
failures have the same root cause, so I've not assigned them a PR.
Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
