This test is flaky on Green Dragon as it often fails when the process state
is "Invalid" in the assert:
self.assertEqual(process.GetState(), lldb.eStateExited)
It seems this is related to just doing "run" which apparently invalidates
the Target's process in case it's still running and needs to be restarted.
Just doing 'continue' on the process (and ignoring the error in case it already
finished) prevents that and makes this consistently pass for me.
Just pushing this out to get Green Dragon back online.

Instead of clearing the launch flags, always pass the target's current
launch flags.

No need to run this test with the multiple variants.

Update tests that were creating an empty LaunchInfo instead of using the
one coming from the target. This ensures target properties are honored.
|
|
Recently added TestTargetAPI.py test "test_launch_simple" is failing on
Arm/AArch64 Linux targets. Putting them to skip until fixed.

Because stdio manipulation unsupported on Windows.

Currently SBTarget::LaunchSimple creates a new LaunchInfo which means it
ignores any target properties that have been set. Instead, it should
start from the target's LaunchInfo and populated the specified fields.

SBLaunchInfo::SetEnvironment(append=true)"
The patch was reverted 27d52cd86a2c because of failures in
TestWeakSymbols.py. These have now been addressed in D83552.
The original commit message was:
This function was documented to overwrite entries with D76111, which was
adding a couple of similar functions. However, this function (unlike the
functions added in that patch) was/is not actually overwriting variables
-- any pre-existing variables would get ignored.
This behavior does not seem to be intentional. In fact, before the refactor in
D41359, this function could introduce duplicate entries, which could
have very surprising effects both inside lldb and on other applications
(some applications would take the first value, some the second one; in
lldb, attempting to unset a variable could make the second variable
become active, etc.).
Overwriting seems to be the most reasonable behavior here, so change the
code to match documentation.

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.

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.

After this patch all remaining tests should pass on macOS when replayed
from a reproducer.
To capture the reproducers:
./bin/llvm-lit ../llvm-project/lldb/test/ --param lldb-run-with-repro=capture
To replay the reproducers:
./bin/llvm-lit ../llvm-project/lldb/test/ --param lldb-run-with-repro=replay

Skip the remaining two failing test in the python_api subdirectory. See
inline comments for the reason why.

Many tests use (commented out) print statement for debugging the test
itself. This patch adds a new trace method to lldbtest to reuse the
existing tracing infrastructure and replace these print statements.

The reproducers only track the creation of objects and not their
destruction. Therefore it keeps all objects alive indefinitely.
|
|
Remove commented out code, fix the indentation and always use the full
path to the executable. The latter is necessary for the test to pass
from reproducer replay.

Fixes or skips tests in the python_api subdirectory that were failing
with passive replay.

This patch marks following tests as xfail for arm-linux target.
lldb/test/API/functionalities/load_using_paths/TestLoadUsingPaths.py

Bugs have been filed for all of them for the corresponding failing
component.

This skips some tests that pass with active replay (which doesn't check
the output) but fail with passive replay. Valid reasons for this
include:
- Checking the output of the process (which doesn't run during replay),
- Checking files that cannot be captured in the VFS (non-existing or
unreadable files or files that are removed during test),
Unfortunately there's no good way to mark a test as supported for active
replay but unsupported for passive replay because the number and order
of API calls needs to be identical during capture and replay. I don't
think this is a huge loss however.

lldb::FileSP is a typedef for std::shared_ptr<lldb_private::File> and
the reproducers cannot instrument a lldb_private constructor.
|
|
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:
On most hosts we were running shell commands with an empty environment.
The only exception was windows, which was inheriting the host enviroment
mostly by accident.
Running the commands in an empty environment does not sound like a
sensible default, so this patch changes Host::RunShellCommand to inherit
the host environment. This impacts both commands run via
SBPlatform::Run (in case of host platforms), as well as the "platform
shell" CLI command.

Some tests set settings and don't clean them up, this leads to side effects in other tests.
The patch removes a global debugger instance with a per-test debugger to avoid such effects.
From what I see, lldb.DBG was needed to determine the platform before a test is run,
lldb.selected_platform is used for this purpose now. Though, this required adding a new function
to the SBPlatform interface.

Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:
lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
lldb-shell :: Reproducer/TestGDBRemoteRepro.test
lldb-shell :: Reproducer/TestMultipleTargets.test
lldb-shell :: Reproducer/TestReuseDirectory.test
lldb-shell :: ExecControl/StopHook/stop-hook-threads.test
lldb-shell :: ExecControl/StopHook/stop-hook.test
lldb-api :: lang/objc/exceptions/TestObjCExceptions.py

the test suite
Summary:
The error message from the construct `assertTrue(a == b, "msg") ` are nearly always completely useless for actually debugging the issue.
This patch is just replacing this construct (and similar ones like `assertTrue(a != b, ...)` with the proper call to assertEqual or assertNotEquals.
This patch was mostly written by a shell script with some manual verification afterwards:
```
lang=python
import sys
def sanitize_line(line):
if line.strip().startswith("self.assertTrue(") and " == " in line:
line = line.replace("self.assertTrue(", "self.assertEquals(")
line = line.replace(" == ", ", ", 1)
if line.strip().startswith("self.assertTrue(") and " != " in line:
line = line.replace("self.assertTrue(", "self.assertNotEqual(")
line = line.replace(" != ", ", ", 1)
return line
for a in sys.argv[1:]:
with open(a, "r") as f:
lines = f.readlines()
with open(a, "w") as f:
for line in lines:
f.write(sanitize_line(line))
```

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.
