This test was timing out because the test inferior was forking a child, which was not terminated
correctly. The test contained provisions to terminate this child, but these were no longer
working. The idea was to wake up upon receiving SIGTERM and then kill the child. However, this
was failing because the test first tried to use SIGHUP, which ended up killing the inferior.
Fix: make sure we catch SIGHUP also.

Currently most of the test files have a separate dwarf and a separate
dsym test with almost identical content (only the build step is
different). With adding dwo symbol file handling to the test suit it
would increase this to a 3-way duplication. The purpose of this change
is to eliminate this redundancy with generating 2 test case (one dwarf
and one dsym) for each test function specified (dwo handling will be
added at a later commit).
Main design goals:
* There should be no boilerplate code in each test file to support the
multiple debug info in most of the tests (custom scenarios are
acceptable in special cases) so adding a new test case is easier and
we can't miss one of the debug info type.
* In case of a test failure, the debug symbols used during the test run
have to be cleanly visible from the output of dotest.py to make
debugging easier both from build bot logs and from local test runs
* Each test case should have a unique, fully qualified name so we can
run exactly 1 test with "-f <test-case>.<test-function>" syntax
* Test output should be grouped based on test files the same way as it
happens now (displaying dwarf/dsym results separately isn't
preferable)
Proposed solution (main logic in lldbtest.py, rest of them are test
cases fixed up for the new style):
* Have only 1 test fuction in the test files what will run for all
debug info separately and this test function should call just
"self.build(...)" to build an inferior with the right debug info
* When a class is created by python (the class object, not the class
instance), we will generate a new test method for each debug info
format in the test class with the name "<test-function>_<debug-info>"
and remove the original test method. This way unittest2 see multiple
test methods (1 for each debug info, pretty much as of now) and will
handle the test selection and the failure reporting correctly (the
debug info will be visible from the end of the test name)
* Add new annotation @no_debug_info_test to disable the generation of
multiple tests for each debug info format when the test don't have an
inferior

The timeout mechanism has been implemented in python,
so there is no more dependence on external utilities
for timing out an inferior dotest.py process.
Platform-specific bits are implemented for POSIX-like
and Windows platforms. There is a small class named
ProcessHelper in process_control.py that needs to be
overridden for platforms that fall outside of the
POSIX-like and Windows platforms.
See http://reviews.llvm.org/D13124 for more details.

On android when debugging an apk we run lldb-server as application user
because the sell user (on non-rooted device) can't attach to an
application. The problem is that "adb pull" will run as a shell user
what can't access to files created by lldb-server because they will be
owned by the application user. This CL changes the oat symbolization
code to run "oatdump --symbolize" to generate an output what is owned
by the shell user.

See the script comments for how to modify your
pylintrc file (e.g. $HOME/.pylintrc) to support
always finding the lldb-specific Python library
directories.
With the pylintrc modification using this script,
the lldb python tests and test inferstructure can
be linted on any of potentially multiple lldb source
trees on the system without further work from
the developer.

There are still a bunch of dependencies on the plug-in, but this helps to

There are also a few more bits we need to move (and abstract, for example the

They pass (and do not hang) when run locally so enable them again. We

See:

for details. On OS X, when LLDB.framework is
not part of the lldb.dylib path, the supporting
executable path is resolved to be the bin directory
sitting next to the lib directory with the dylib
lives. Not a perfect solution, but we also can't
base it on the executable path since both Python
and the lldb driver can be the executable.

Summary:
With this change DWARFASTParserClang::CompleteTypeFromDWARF returns false if
DWARFASTParserClang::ParseChildMembers returns false. Similarly, it returns
false if any base class is of an incomplete type. This helps in cases like
these:
class Foo
{
public:
std::string str;
};
...
Foo f;
If a file with the above code is compiled with a modern clang but without
the -fno-limit-debug-info (or similar) option, then the DWARF has only
a forward declration for std::string. In which case, the type for
"class Foo" cannot be completed. If LLDB does not detect that a child
member has incomplete type, then it wrongly conveys to clang (the LLDB
compiler) that "class Foo" is complete, and consequently crashes due to
an assertion failure in clang when running commands like "p f" or
"frame var f".

* --results-formatter-options renamed to --results-formatter-option,
with short version of -O
* Multiple --results-formatter-option=OPTION can be specified. The
comma-separating mechanism has been removed.
* XunitFormatter options modified: -n and -r are now short forms of
--ignore-skip-name and --ignore-skip-reason. Those long option
names were tweaked lightly. They also can be specified multiple
times on the command line. The comma-separating, multiple-pattern-
per-option mechanism has been removed.
One can now specify:
dotest.py --results-file stdout -O-ndsym -O-nlldb-mi
for example, to ignore reporting skips for dsym-related or lldb-mi-related
tests in the xUnit report.

Summary:
The following situation occured in TestAttachResume:
The inferior was stoped at a breakpoint and we did a continue, immediately followed by a detach.
Since there was a trap instruction under the IP, the continue did a step-over-breakpoint before
resuming the inferior for real. In some cases, the detach command was executed between these two
events (after the step-over stop, but before continue). Here, public state was running, but
private state was stopped. This caused a problem because HaltForDestroyOrDetach was checking the
public state to see whether it needs to stop the process (call Halt()), but Halt() was checking
the private state and concluded that there is nothing for it to do.
Solution: Instead of Halt() call SendAsyncInterrupt(), which will then cause Halt() to be
executed in the context of the private state thread. I also rename HaltForDestroyOrDetach to
reflect it does not call halt directly.

The default case doesn't need to be here as the switch covers

in the future, the compiler would start to warn about the new
