Greg Clayton 7202d1c2f6 Fix lldb-vscode logging and enable logging for all lldb-vscode tests.
Summary:
This patch fixes logging to log incoming packets which was removed during a refactor.

We also enable logging to a "vscode.txt" file for each lldb-vscode test by creating the log file in the build artifacts directory for each test. This allows users to see the packets for their tests if needed and the log file is in a directory that will be removed after tests have been run.

Greg Clayton 9cb227f561 Stop emitting a breakpoint for each location in a breakpoint when responding to breakpoint commands.
Summary: The VS Code DAP expects on response for each breakpoint that was requested. If we responsd with multiple entries for one breakpoint the VS Code UI gets out of date. Currently the VS code DAP doesn't handle one breakpoint with multiple locations. If this ever gets fixed we can modify our code.

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

Hector Diaz 45e3f6660c Auto-completion bug fix for dot operator
Summary:
There was a bug on LLDB VSCode where there was the following behavior:

//Code

```
struct foo {
    int bar:
};
...
foo my_foo = {10};
```

Trying to auto-complete my_foo.b with my_foo.bar resulted instead with my_foo.my_foo.bar

This diff fixes this bug and adds some tests to check correct behavior.

It also fixes the same bug using the arrow operator (->) when user manually requests completions.
TODO: Fix bug where no recommended completions are automatically shown with arrow operator

Raphael Isemann a52a11139c [lldb][NFC] Remove 'from __future__ import print_function' from all tests that don't actually call 'print()'
Summary:
A lot of tests do this trick but the vast majority of them don't even call `print()`.

Most of this patch was generated by a script that just looks at all the files and deletes the line if there is no `print (` or `print(` anywhere else in the file.
I checked the remaining tests manually and deleted the import if we never call print (but instead do stuff like `expr print(...)` and similar false-positives).
I also corrected the additional empty lines after the import in the files that I manually edited.

Michał Górny 8d9400b65b [lldb] [Process/NetBSD] Improve threading support
Implement major improvements to multithreaded program support.  Notably,
support tracking new and exited threads, associate signals and events
with correct threads and support controlling individual threads when
resuming.

Firstly, use PT_SET_EVENT_MASK to enable reporting of created and exited
threads via SIGTRAP.  Handle TRAP_LWP events to keep track
of the currently running threads.

Secondly, update the signal (both generic and SIGTRAP) handling code
to account for per-thread signals correctly.  Signals delivered
to the whole process are reported on all threads, while per-thread
signals and events are reported only to the specific thread.
The remaining threads are marked as 'stopped with no reason'.  Note that
NetBSD always stops all threads on debugger events.

Thirdly, implement the ability to set every thread as running, stopped
or single-stepping separately while continuing the process.  This also
provides the ability to send a signal to the whole process or to one
of its thread while resuming.

Pavel Labath aa16bf15fe [lldb-vscode] Fix a race in test_extra_launch_commands
Summary:
The test used a non-stopping "run" command to launch the process. This
is different from the regular launch with no extra launch commands,
which uses eLaunchFlagStopAtEntry to ensure that the process stops
straight away.

I'm not really sure what's supposed to happen in non-stop-at-entry mode,
or if that's even supported, but what ended up happening was the launch
packet got a reply while the process was running. Then the test case did
a continue_to_next_stop(), which queued a *second* resume request
(along with the internal "resumes" which were being issued as a part of
normal process startup). These two resumes ended up chasing each other's
tails inside lldb in a way which produced hilarious log traces.
Surprisingly, the test ended up passing most of the time, but it did
cause spurious failures when the test seemed to miss a breakpoint.

This changes the test to use stop-at-entry mode in the manual launch
sequence too, which seems to be enough to make the test pass reliably.

Walter Erquinigo 2c7c528d7a [lldb-vscode] support the completion request
Summary:
The DAP has a completion request that has been unimplemented. It allows showing autocompletion tokens inside the Debug Console.
I implemented it in a very simple fashion mimicking what the user would see when autocompleting an expression inside the CLI.
There are two cases: normal variables and commands. The latter occurs when a text is prepepended with ` in the Debug Console.
These two cases work well and have tests.

Frederic Riss 3fb4e49a68 [Testsuite] Get rid of most of the recursive shared library Makefiles
Most of the secondary Makefiles we have are just a couple variable
definitions and then an include of Makefile.rules. This patch removes
most of the secondary Makefiles and replaces them with a direct
invocation of Makefile.rules in the main Makefile. The specificities
of each sub-build are listed right there on the recursive $(MAKE)
call. All the variables that matter are being passed automagically by
make as they have been passed on the command line. The only things you
need to specify are the variables customizating the Makefile.rules
logic for each image.

This patch also removes most of the clean logic from those Makefiles
and from Makefile.rules. The clean rule is not required anymore now
that we run the testsuite in a separate build directory that is wiped
with each run. The patch leaves a very crude version of clean in
Makefile.rules which removes everything inside of $(BUILDDIR). It does
this only when the $(BUILDDIR) looks like a sub-directory of our
standard testsuite build directory to be extra safe.

Pavel Labath 45e3ce8d76 [dotest] Centralize initialization commands even more
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.

Jan Kratochvil 2b38951799 [lldb] Increase testsuite packet-timeout 5secs -> 1min
rL357954 did increase `packet-timeout` 1sec -> 5secs. Which is IMO about the
maximum timeout reasonable for regular use. But for testsuite I think the
timeout should be higher as the testsuite runs in parallel and it can be run
even on slow hosts and with other load (moreover if it runs on some slow arch).

I have chosen 60 secs, that should be enough hopefully.  Larger value could
make debugging with hanging `lldb-server` annoying.

This patch was based on this testsuite timeout:

Pavel Labath 08c38f77c5 Revert "Implement xfer:libraries-svr4:read packet"
D62502, together with D62503 have broken the builds which have XML
support enabled. Reverting D62503 (r364355) fixed that, but has broken
has left some of the tests introduced by D62502 broken more or less
nondeternimistically (it depended on whether the system happens to place
the library list near unreadable pages of memory). I attempted to make a
partial fix for this in r364748, but Jan Kratochvil pointed out that
this reintroduces the problem which reverting D62503 was trying to
solve.

So instead, I back out the whole thing so we can get back to a clean
slate that works for everyone. We can figure out a way forward from
there.

This reverts r364748, r363772 and r363707.

Pavel Labath 80b6b705f8 Stabilize TestGdbRemoteLibrariesSvr4Support
on some systems this test fails because the two methods it uses to
cross-reference the data don't match in the case of the vdso module. The
"read from /proc/%pid/maps" method returns "[vdso]", while the method
which reads it from the linker rendezvous structures returns
"linux-vdso.so.1". Neither of the two names match any actual file.

This restricts the test to only consider the libraries that we ourselves
have added to the test, minimizing the impact of system dependencies
that we cannot control.

Antonio Afonso fda83c9b0b Implement xfer:libraries-svr4:read packet
Summary:
This is the fourth patch to improve module loading in a series that started here (where I explain the motivation and solution): D62499

Implement the `xfer:libraries-svr4` packet by adding a new function that generates the list and then in Handle_xfer I generate the XML for it. The XML is really simple so I'm just using string concatenation because I believe it's more readable than having to deal with a DOM api.

Jan Kratochvil 8c82c41262 [lldb] [test] Extend D55859 symbols.enable-external-lookup=false for more testcases
D55859 <https://reviews.llvm.org/D55859> has no effect for some of the
testcases so this patch extends it even for (all?) other testcases known to me.
LLDB was failing when LLDB prints errors reading system debug infos
(`*-debuginfo.rpm`, DWZ-optimized) which should never happen as LLDB testcases
should not be affected by system debug infos.

`lldb/packages/Python/lldbsuite/test/api/multithreaded/driver.cpp.template` is
using only SB API which does not expose `ModuleList` so I had to call
`HandleCommand()` there.

`lldb-test.cpp` could also use `HandleCommand` and then there would be no need
for `ModuleListProperties::SetEnableExternalLookup()` but I think it is cleaner
with API and not on based on text commands.

Pavel Labath e8687e6ee1 Make TestVSCode_step pass reliably
Summary:
The test was failing occasionally (1% of runs or so), because of
unpredictable timings between the two threads spawned by the test. If
the second thread hit the breakpoint right as we were stepping out of
the function on the first thread, we would still be stuck at the inner
frame when the process stopped.

This would cause errors like:
    File "/home/worker/lldb-x86_64-debian/lldb-x86_64-debian/llvm/tools/lldb/packages/Python/lldbsuite/test/tools/lldb-vscode/step/TestVSCode_step.py", line 67, in test_step
      self.assertEqual(x1, x3, 'verify step out variable')
  AssertionError: 2 != 1 : verify step out variable

AFAICT, lldb-vscode is doing the right thing here, and the problem is
that the test is not taking this sequence of events into account. Since
the test is about testing stepping, it does not seem necessary to have
threads in the inferior at all, so I just rewrite the test to execute
the code we're supposed to step through directly on the main thread.

Summary:
After https://reviews.llvm.org/D59828 and https://reviews.llvm.org/D59849,
I believe the problems with these tests hanging have been solved.

I tried enabling all of them on my machine, and got two failures:

- One of them was spawning a child process that lives for 5 seconds, waited
  for 5 seconds to attach to the child, and failed because the child wasn't
  there.

- The other one was a legit failure because shell expansion of arguments doesn't
  work on Linux.

This tests enables all lldb-vscode tests on Linux except for "launch process
with shell expansion of args" (which doesn't work), and fixes the other broken
test by reducing the time it waits before attaching to its child process.

Jorge Gorbe Moya 4665aca8ca [lldb-vscode] Add logic to handle EOF when reading from lldb-vscode stdout.
Summary:
This change prevents the lldb-vscode test harness from hanging up waiting for
new messages when the lldb-vscode subprocess crashes.

Now, when an EOF from the subprocess pipe is detected we enqueue a `None` packet
in the received packets list. Then, during the message processing loop, we can
use this `None` packet to tell apart the case where lldb-vscode has terminated
unexpectedly from the normal situation where no pending messages means blocking
and waiting for more data.

I believe this should be enough to fix the issues with these tests hanging on
multiple platforms. Once this lands, I'll prepare and test a separate change
removing the @skipIfLinux annotations.

Pavel Labath 0af864b4b2 Fix lldb-server test suite for python3
Summary:
This patch finishes the python3-ification of the lldb-server test suite.
It reverts the partial attempt in r352709 to encode/decode the string
via utf8 before writing to the socket. This wasn't enough because the
gdb-remote protocol can sometimes (but not very often) carry binary
data, and the utf8 codec chokes on that. Instead I add utility functions
to the "seven" module for performing "identity" transformations on the
byte data. This basically drills back the hole in the python type system
that the string/bytes distinction was supposed to plug. That is not
ideal, but was the best solution of the alternatives I could come up
with. The options I considered were:
- make use of the type system to add type safety to the test suite: This
  required making a lot of changes to the test suite, since most of the
  strings would now become byte objects instead, and it was not even
  fully clear to me where to draw the line. One extreme solution would
  be to just use byte objects everywhere, as the protocol doesn't
  support non-ascii characters anyway. However, this appeared to be:
  a) weird, because most of the protocol actually deals with strings,
     but we would have to prefix everything with 'b'
  b) clunky, because the handling of the bytes objects is sufficiently
     different in PY2 and PY3 (e.g. b'a'[0] is a string in PY2, but an
     int in PY3).
- using the latin1 codec (which gives an identity transformation for the
  first 256 code points of unicode) instead of the custom
  bytes_to_string functions. This almost could work, but it was still
  slightly different between python 2 and 3, because in PY2 in would
  return a unicode object, which would then cause problems when
  combined with regular strings if it contained 8-bit chars.

With this in mind, I think the best solution for the time being is to
just coerce everything into the string type as early as possible, and
have things proceed indentically on both python versions. Once we stop
supporting python3, we can revisit the idea of using bytes objects more
prevasively.

It looks like I was too hasty to submit the previous patch. It does fix

This happens because the gdb-remote protocol can sometimes (but not very

characters fails.

We understand that people may be surprised that we're moving the header

Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and

	lit/lit-lldb-init:
		settings set symbols.enable-external-lookup false
	packages/Python/lldbsuite/test/lldbtest.py:
		self.runCmd('settings set symbols.enable-external-lookup false')

But those are not in effect during MI part of the testsuite. Another problem is
that symbols.enable-external-lookup (read by GetEnableExternalLookup) has been
currently read only by LocateMacOSXFilesUsingDebugSymbols and therefore it had
no effect on Linux.

On Red Hat platforms (Fedoras, RHEL-7) there is DWZ in use and so

	AssertionError: error: inconsistent pattern ''^.+?\n'' for state 0x5f
	(matched string: warning: (x86_64) /lib64/libstdc++.so.6 unsupported
	DW_FORM values: 0x1f20 0x1f21
It is the only testcase with this error. It happens due to:
	(lldb) target create "/lib64/libstdc++.so.6"
	Current executable set to '/lib64/libstdc++.so.6' (x86_64).
	(lldb) b main

which happens only with gcc-base-debuginfo rpm installed (similarly for other packages).

Pavel Labath 410c5acf27 Fixup r331049 (FileSpec auto-normalization)
A typo in the patch (using syntax instead of m_syntax) resulted in the
normalization not working properly for windows filespecs when the syntax
was passed as host-native. This did not affect the unit tests, as all of
those pass an explicity syntax, but failed gloriously when running the
full test suite.

I also fix an expectation in an lldb-mi test, which was now failing
because it was expecting a path to be echoed verbatim, but we were now
normalizing it.

As a drive-by, this also fixes the default-in-fully-covered-switch
warning and removes an unused argument from the NeedsNormalization
function.

Frederic Riss 34ec0bfb5e [debugserver] Fix handling of the 'g' packet
LLDB doesn't use this packet so we never hit this, but it looks like
some other projects talk to debugserver and are hitting an assert
(https://github.com/derekparker/delve/issues/1015).

We had an off by 1 in the accounting of the FPU structure sizes.
I added a test that basically just check that 'g' doesn't return
an error (currently it assert in debug builds). I didn't make
it an lldb-server test because it looks like lldb-server doesn't

Frederic Riss cd90f878d4 [debugserver] Fix LC_BUILD_VERSION load command handling.
Summary:
In one of the 2 places the LC_BUILD_VERSION load command is handled, there
is a bug preventing us from actually handling them (the address where to
read the load command was not updated). This patch factors reading the
deployment target load commands into a helper and adds testing for the 2
code paths calling the helper.

The testing is a little bit complicated because the only times those load
commands matter is when debugging a simulator process. I added a new
decorator to check that a specific SDK is available. The actual testing was
fairly easy once I knew how to run a simulated process.

Pavel Labath 63047d05c0 [dotest] Clean up test folder clean-up
Summary:
This patch implements a unified way of cleaning the build folder of each
test. This is done by completely removing the build folder before each
test, in the respective setUp() method. Previously, we were using a
combination of several methods, each with it's own drawbacks:
- nuking the entire build tree before running dotest: the issue here is
  that this did not take place if you ran dotest manually
- running "make clean" before the main "make" target: this relied on the
  clean command being correctly implemented. This was usually true, but
  not always.
- for files which were not produced by make, each python file was
  responsible for ensuring their deleting, using a variety of methods.

With this approach, the previous methods become redundant. I remove the
first two, since they are centralized. For the other various bits of
clean-up code in python files, I indend to delete it when I come
across it.

Pavel Labath 107052ff9d Next batch of test-tree-cleaning changes
Summary:
The changes here fall into several categories.

- some tests were redirecting inferior stdout/err to a file. For these I
  make sure we use an absolute path for the file. I also create a
  lldbutil.read_file_on_target helper function to encapsulate the
  differences between reading a file locally and remotely.
- some tests were redirecting the pexpect I/O into a file. For these I
  use a python StringIO object to avoid creating a file altogether.
- the TestSettings inferior was creating a file. Here, I make sure the
  inferior is launched with pwd=build-dir so that the files end up
  created there.
- lldb-mi --log (used by some tests) creates a log file in PWD without
  the ability say differently. To make this work I make sure to run
  lldb-mi with PWD=build_dir. This in turn necessitated a couple of
  changes in other lldb-mi tests, which were using relative paths to
  access the source tree.

Summary:
On PPC64, the tested functions were being entered through their local entry point, while the tests expected the program to stop at the function start address, that, for PPC64, corresponds to the global entry point.

To fix the issue, the test program was modified to call the functions to be tested through function pointers, which, on PPC64, force the calls through the global entry point, while not affecting the test on other platforms.

Pavel Labath f3a9ab07aa Fix a couple of more tests to not create files in the source tree
Summary:
These were not being flaky, but they're still making the tree dirty.

These tests were using lldbutil.append_to_process_working_directory to
derive the file path so I fix them by modifying the function to return
the build directory for local tests.

Technically, now the path returned by this function does not point to
the process working directory for local tests, but I think it makes
sense to keep the function name, as I think we should move towards
launching the process in the build directory (and I intend to change
this for the handful of inferiors that actually care about their PWD,
for example because they need to create files there).

Adrian Prantl 5ec76fe720 Compile the LLDB tests out-of-tree.
This patch is the result of a discussion on lldb-dev, see
http://lists.llvm.org/pipermail/lldb-dev/2018-January/013111.html for
background.

For each test (should be eventually: each test configuration) a
separate build directory is created and we execute

  make VPATH=$srcdir/path/to/test -C $builddir/path/to/test -f $srcdir/path/to/test/Makefile -I $srcdir/path/to/test

In order to make this work all LLDB tests need to be updated to find
the executable in the test build directory, since CWD still points at
the test's source directory, which is a requirement for unittest2.

Although we have done extensive testing, I'm expecting that this first
attempt will break a few bots. Please DO NOT HESITATE TO REVERT this
patch in order to get the bots green again. We will likely have to
iterate on this some more.

Pavel Labath 225b79524d Remove HostThreadLinux/Free/NetBSD
Summary:
These classes existed only because of the GetName() static function,
which can be moved to a more natural place anyway. I move the linux
version to NativeProcessLinux (and get rid of ProcFileReader), the
freebsd version to ProcessFreeBSD (and fix a bug where it was using the
current process ID, instead of the inferior pid), and remove the NetBSD
version (which was probably incorrect anyway, as it assumes the current
process instead of the inferior.

I also add an llgs test to that verifies thread names are read
correctly.

Pavel Labath bf37a037d0 BreakpointResolverFileLine: Restrict move-to-nearest-code from moving across function boundaries
Summary:
This fixes the case where a user tries to set a breakpoint on a source
line outside of any function (e.g. because that code is #ifdefed out, or
the compiler did not emit code for the function, etc.) and we would
silently move the breakpoint to the next function.

Now we check whether the line range of the resolved symbol context
function matches the original line number. We reject any breakpoint
locations that appear to move the breakpoint into a new function. This
filtering only happens if we have full debug info available (e.g. in
case of -gline-tables-only compilation, we still set the breakpoint on
the nearest source line).

Sean Callanan 9984624edf Disable the lldb-mi tests on remote platforms.
Currently on remote platforms the lldb-mi tests fail, which means they time out.
Given how many of the lldb-mi tests there are, this means a long wait.

Pavel Labath ebe25fb845 Fix flakyness in TestGdbRemoteHostInfo
this test was using the VPATH hack to avoid having a copy of the
inferior source code. This makes the test fail if in happens to run
concurrently with a test in the parent folder. Fix that by moving it up
to the parent.

Kamil Rytarowski 47e7d7fe85 Support NetBSD Thread ID in lldb-server tests
Summary:
Native Thread ID is retrieved with _lwp_self() on NetBSD.

The returned value is of type int32_t, but for consistency with other Operating Systems cast it to uint64_t.
