`sets.Set` has been deprecated in favor of `set` since 2.6, and
`string.maketrans` has to be special cased. In Python 3 there
is `str.maketrans`, `bytes.maketrans`, and `bytearray.maketrans`
and you have to choose the correct one. So we need to introduce
a runtime version check at this site.

We tried implementing something akin to a conditionalExpectedFailure
decorator for unittest2. We did this by making use of some
implementation details of the unittest2 module. In an effort to make
this work with unittest, this patch removes the reliance on the
implementation details. I have a hard time wrapping my head around
how this all works with the deeply nested decorators, but the spirit
of the patch here is to do do the following: If the condition function
is true, use the original unittest2.expectedFailure decorator. Otherwise
don't use any decorator, just call the test function.

Absolute imports were introduced in Python 2.5 as a feature
(e.g. from __future__ import absolute_import), and made default
in Python 3.
When absolute imports are enabled, the import system changes in
a couple of ways:
1) The `import foo` syntax will *only* search sys.path. If `foo`
isn't in sys.path, it won't be found. Period. Without absolute
imports, the import system will also search the same directory
that the importing file resides in, so that you can easily
import from the same folder.
2) From inside a package, you can use a dot syntax to refer to higher
levels of the current package. For example, if you are in the
package lldbsuite.test.utility, then ..foo refers to
lldbsuite.test.foo. You can use this notation with the
`from X import Y` syntax to write intra-package references. For
example, using the previous locationa s a starting point, writing
`from ..support import seven` would import lldbsuite.support.seven
Since this is now the default behavior in Python 3, this means that
importing from the same directory with `import foo` *no longer works*.
As a result, the only way to have portable code is to force absolute
imports for all versions of Python.
See PEP 0328 [https://www.python.org/dev/peps/pep-0328/] for more
information about absolute and relative imports.

This follows the spirit of a previous patch which did essentially
the same thing. In Python 3, when you use Popen.communicate(),
you get back a bytes object which cannot normally be treated as
a string. We could decode this manually, but universal_newlines=True
does this automatically, and there's no disadvantage to doing so
even on Python 2. So just enable it always.

Python 3 introduces the `timeout` keyword argument on Popen.wait().
If our patched version doesn't support keyword arguments, then when
the internal Python implementation attempts to call wait() with the
keyword argument, things will explode.

By default in Python 3, check_output() returns a program's output as
an encoded byte sequence. This means it returns a Py3 `bytes` object,
which cannot be compared to a string since it's a different fundamental
type.
Although it might not be correct from a purist standpoint, from a
practical one we can assume that all output is encoded in the default
locale, in which case using universal_newlines=True will decode it
according to the current locale. Anyway, universal_newlines also
has the nice behavior that it converts \r\n to \n on Windows platforms
so this makes parsing code easier, should we need that. So it seems
like a win/win.

This module was originally intended to be imported by top-level
scripts to be able to find the LLDB packages and third party
libraries. Packages themselves shouldn't need to import it,
because by the time it gets into the package, the top-level
script should have already done this. Indeed, it was just
adding the same values to sys.path multiple times, so this
patch is essentially no functional change.
To make sure it doesn't get re-introduced, we also delete the
`use_lldb_suite` module from `lldbsuite/test`, although the
original copy still remains in `lldb/test`

The `commands` module was deprecated in 2.7 and removed in 3.x.
As a workaround, we introduce a new module `seven` in

functionality for cases where it is not available.

Summary:
The code which was preventing the usage of the OS plugin while detach is in
progress also prevented us to update the thread list correctly. This resulted
in an empty thread list, which confused the detaching logic. Change the
condition do only do what it says (disable the usage of the OS plugin).

Summary:
The solution to bug 24074,rL249673 needed
to parse the function information from the Dwarf in order
to set the SymbolContext. For that, GetFunction was called
for the parent in GetTypeForDIE, which parses the
ChildParameters and in the flow, GetTypeForDIE was called
for one of the sibling die and so an infinite
loop was triggered by calling GetFunction repeatedly for the
same function.
The changes in this revision modify the GetTypeForDIE to only
resolve the function context in the Type Lookup flow and so
prevent the infinite loop.
A testcase has also been added to check for regression in the
future and a test vector had been added to the testcase of
24074.

For convenience, we had added the folder that dotest.py was in
to sys.path, so that we could easily write things like
`import lldbutil` from anywhere and any test. This introduces
a subtle problem when using Python's package system, because when
unittest2 imports a particular test suite, the test suite is detached
from the package. Thus, writing "import lldbutil" from dotest imports
it as part of the package, and writing the same line from a test
does a fresh import since the importing module was not part of
the same package.
The real way to fix this is to use absolute imports everywhere. Instead
of writing "import lldbutil", we need to write "import
lldbsuite.test.util". This patch fixes up that and all other similar
cases, and additionally removes the script directory from sys.path
to ensure that this can't happen again.

packages/Python/lldbsuite is now a Python package, and it relies
on its __init__.py being called to do package-level initialization.
If you exec packages/Python/lldbsuite/dotest.py directly, you won't
get this package level initialization, and things will fail. But
without this patch, this is exactly what dosep itself does. To
launch the multi-processing fork, it was hardcoding a path to
dotest.py and exec'ing it from inside the package.
The fix here is to get the path of the top-level script, and
then exec'ing that instead. A more robust solution would involve
refactoring the code so that dosep execs some internal script that
imports lldbsuite, but that's a bit more involved.

It turns out that lldbtest_config was being imported locally to "lldbsuite.test" instead of globally, so when the test cases got individually brought by a global import via __import__ by unittest2, they did not see the lldbtest_config import, and ended up importing a new separate copy of it, with lldbExec unset
This is a simple hackaround that brings lldbtest_config to global visibility and makes sure the configuration data is correctly shared

This is the conclusion of an effort to get LLDB's Python code
structured into a bona-fide Python package. This has a number
of benefits, but most notably the ability to more easily share
Python code between different but related pieces of LLDB's Python
infrastructure (for example, `scripts` can now share code with
`test`).

The idea behind this patch is to expose the meat of
LLDB's Python infrastructure (test suite, scripts, etc)
as a single package. This makes reusability and code
sharing among sub-packages easy.
