Summary:
This adds a SBDebugger::GetBuildConfiguration static function, which
returns a SBStructuredData describing the the build parameters of
liblldb. Right now, it just contains one entry: whether we were built
with XML support.
I use the new functionality to skip a test which requires XML support,
but concievably the new function could be useful to other liblldb
clients as well (making sure the library supports the feature they are
about to use).

These were missed in the great refactor because they were added
concurrently with it. Since we started running tests in a more parallel
fashion they started to be flaky. This should fix it.
Now that we are no longer polluting the source tree, I also delete the
bit of custom cleanup code specific to these tests.

The test was generating long unix socket names, and the addition of a
new folder in the previous patch pushed it over the limit (although
linux has a fairly generous limit for path names, this does not apply to
unix sockets).
Modify the test to use a shorter name instead.

The reason this test was disabled is no longer relevant. However, it
didn't turn into an unexpected success because of a syntax error in the
test itself. This commit fixes that and re-enables the test.
llvm-svn: 325339
Since we now can run multiple tests from the same directory at once, we
need to include the test name in the remote test directory instead.
I'm not sure if the test_number in the remote path is necessary anymore
(or even if it was ever necessary), but I choose to leave it in for now.

Summary:
Due to in-tree builds, we were parallelizing the tests at the directory
level. Now that the tests are built out-of-tree, we can remove this
limitation and paralelize at file level instead.
This decreases test suite time by about 10% for me, which is not
world-shattering, but it makes the code slightly simpler and will also
allow us to merge tests which were artificially spread over multiple
folders (TestConcurrentEvents...) to work-around this limitation.
To make this work, I've also needed to include the test file name in the
build directory name, as just the test method name is not unique enough
(plenty of tests have a test method called "test" or similar).
While doing this, I've found a couple of tests that are taking waaay longer then
they ought to (TestBreakpointCaseSensitivity -- 90 seconds), which I plan to
look into in the future.

This test uses XML packets, but libxml is an optional dependency of
lldb, and this test fails if it is not present.
I'm leaving this enabled on mac, as thats the only platform that's
likely to have libxml always available, but ideally we should have a way
to skip this based on build configuration. I'll see if I can whip
something like that up soon, but for the time being, this unblocks the
buildbots.

arch incompat with spec in file so it's rejected and the test fails.
will look into this later, will be a test case issue not a test issue;
test case may only be valid when lldb is built for/running on an x86_64
system.

This patch makes LLDB's clang module cache path customizable via
settings set target.clang-modules-cache-path <path> and uses it in the
LLDB testsuite to reuse the same location inside the build directory
for LLDB and clang.

This only worked on MacOS, which now ships a newer version of
python without this bug. As such, we don't leak the fd, and
this test is not needed anymore (as it also hardcoded the python
version in the check).

Summary:
Update makefiles to specify -fPIC in Makefile.rules and only throw -fPIC when building a shared library. This change is necessary to allow building the lldb tests on Windows where -fPIC is not a valid option.
Update a few places to Python 3.x syntax

Summary:
The test was trying to reproduce a bug in handling of two concurrent
events, which was impossible to do reliably in a black-box style test.
In practice, this meant the test was only ever failing on remote
targets, as these were slow enough to trigger this.
Fortunately, we now have the ability to mock the server side of the
connection, which means we can simulate the failure deterministically,
so I rewrite the test to use the new gdb-client framework.
I've needed to add a couple of new packets to the mock server to be able
to do this. Instead of trying to guess how a "typical" gdb-client test
will want to handle this, I throw an exception in the implementation to
force the user to override them (the packets are only sent if the test
explicitly performs some action which will trigger them, so a basic test
which e.g. does not need the "continue" functionality will not need to
implement them).

The change in r324488 dropped the existing category attribute in for
instance methods. This patch corrects that.

llvm-svn: 324492
Inlined tests have a test function that is actually an instance method,
which requires a slightly different approach when it comes to setting
the category attribute. The attribute must be set on the actual
function, rather than on a particular instance.

This patch creates a <test>.dwarf, <test>.dwo, etc., build directory for each testcase variant.
Most importantly, this eliminates the need for the per-test lock file in the source directory.
Tests that are marked as NO_DEBUG_INFO_TESTCASE and build with
buildDefault() are built in a <test>.default build directory.

Summary:
This changes the way we store the debug info variant to make it
available earlier in the test bringup: instead of it being set by the
test wrapper method, it is set as a *property* of the wrapper method.
This way, we can inspect it as soon as self.testMethodName is
initialized. The retrieval is implemented by a new function
TestBase.getDebugInfo(), and all that's necessary to make it work is to
change self.debug_info into self.getDebugInfo().
While searching for debug_info occurences i noticed that TestLogging is
being replicated for no good reason, so I removed the replication there.

I have found LLDB cannot find separate debug info of Fedora /usr/bin/gdb.
It is because:
lrwxrwxrwx 1 root root 14 Jan 25 20:41 /usr/bin/gdb -> ../libexec/gdb*
-rwxr-xr-x 1 root root 10180296 Jan 25 20:41 /usr/libexec/gdb*
ls: cannot access '/usr/lib/debug/usr/bin/gdb-8.0.1-35.fc27.x86_64.debug': No such file or directory
-r--r--r-- 1 root root 29200464 Jan 25 20:41 /usr/lib/debug/usr/libexec/gdb-8.0.1-35.fc27.x86_64.debug
FYI that -8.0.1-35.fc27.x86_64.debug may look confusing, it was always just
.debug before.
Why is /usr/bin/gdb a symlink is offtopic for this bugreport, Fedora has it so
for some reasons.
It is always safest to look at the .debug file only after resolving all
symlinks on the binary file.

I have found the lookup by build-id

LLDB tries the build-id hex string in uppercase but Fedora uses lowercase.
xubuntu-16.10 also uses lowercase during my test:

LLDB queries Spotlight to locate .dSYM bundles based on the UUID
embedded in a binary, and because the UUID is a hash of filename and
.text section, there *will* be conflicts inside $BUILD_DIR.

Using the "run_to_{source,name}_breakpoint will allow us to remove
a lot of boiler-plate from the testsuite. We mostly use source
breakpoints, but some tests use by name ones so this was needed.

The mock server was sending acks back in response to spurious acks from
the client, but the client was not prepared to handle these. Most of the
time this would work because the only time the client was sending
unsolicited acks is after the initial connection, and there reply-ack
would get ignored in the "flush all packets from the server" loop which
came after the ack. However, this loop had only a 10ms delay, and
sometimes this was not enough to catch the reply (which meant the
connection got out of sync, and test failed).
Since this behavior not consistent with how lldb-server handles this
situation (it just ignores the ack), I fix the mock server to do the
same.

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.
