Johnny Chen 47ceb03210 Add a utility function to lldbtest.py to return the line number of a matched string
within a file.  This is to be used within the test case to avoid hardcoded line number.

array_types/TestArrayTypes.py is modified first to use this pattern.  Other test modules
to follow.

Testsuite: don't set breakpoints by exact file & line number

llvm-svn: 116270
2010-10-11 23:52:19 +00:00
Johnny Chen 707b3c9c73 Added the capability for the test driver to relocate the tests and the intermediate
files to a different top level directory than those specified on the command line.

When relocated, the test clanups normally performed afterwards after each test method
and after each test class will not be exercised at all.  This allows for an easier
postmortem analysis of test failures.

Example:

./dotest.py -v -t -r /tmp/lldbtest types

will create a /tmp/lldbtest directory which houses the types directory and its supported
files.

Files modified:

o dotest.py, lldbtest.py:

  Add logic to process '-r dir' option to support relocating the tests to a different
  top level directory instead of exected in place.

o darwin.py, test/types/Makefile:

  The 'make clean' should only clean the minimum .o and .d files.

Johnny Chen 65045f2168 o TestStdCXXDisassembly.py:
Update the expected match string.

o lldbtest.py:

  Indicate when a command fails, even if there is nothing in the error stream.

o TestHelp.py:

  Add a regression test case for 'help image dump symtab'.

o CommandObjectHelp.cpp:

  Some of the logic branches with successful help command results were not tagged
  with a Success Status.  They are fixed now.  This is important for Python
  interaction.

Johnny Chen 0ed37c9615 o SBtarget.cpp/.h:
Temporarily commenting out the deprecated LaunchProcess() method.
  SWIG is not able to handle the overloaded functions.

o dotest.py/lldbtest.py:

  Add an '-w' option to insert some wait time between consecutive test cases.

o TestClassTypes.py:

  Make the breakpoint_creation_by_filespec_python() test method more robust and
  more descriptive by printing out a more insightful assert message.

o lldb.swig: Coaches swig to treat StateType as an int type, instead of a C++ class.

Johnny Chen 67af43f04f Make the test module with unique name instead of just the generic name TestDisassembly.
Add a utility function to lldbtest.py to get the native pointer size of the host os.

Johnny Chen da88434b39 o Added a new feature to the test framework to skip long running tests conditionally.
To not skip long running tests, pass '-l' to the test driver (dotest.py).

  An example:

    @unittest2.skipIf(TestBase.skipLongRunningTest(), "Skip this long running test")
    def test_foundation_disasm(self):
        ...

o Added a long running disassemble test to the foundation directory, which iterates
  the code symbols from Foundation.framework and kicks off a disassemble command for
  for the named function symbol.  Found a crasher: rdar://problem/8504895.

o Plus added/updated some comments for the TestBase class.

Johnny Chen b052f6c595 Added a generic_type_tester() to the TestBasicTypes class to be used for
testing various combinations of displaying variales of basic types.

The generic_type_tester() works by first capturing the golden output produced
by the printf stmts of ./a.out, creating a list of (var, value) pairs, and then
running the a.out to a stop point, and comparing the 'frame variable var' output
against the list of (var, value) pairs.

Modified int_type() and added long_type() to use generic_type_tester().

Also modified TestBase.expect() such that substring matching also return ok if
the substring starts at the 0-th position.

Johnny Chen c70b02a324 Checked in an initial template for the types directory. Right now, it doesn't
actually test-and-compare anything yet.  The lldbtest.TestBase has an added
method setTearDownCleanup(dictionary=None) to facilitate running the cleanup
right after each data type test is run.  The test case can pass a dictionary
object when registering the test case cleanup.

There is currently only int_type test in the repository.

2010-09-21 23:47:01 +00:00
Johnny Chen 9c48b8d79c Added a subtest to exercise the capability of lldb Python objects to print
themselves.  Right now, it tests a breakpoint both before and after it has been
resolved.

Updated lldbtest.TestBase.expect() with an additional keyword argument 'exe' (
default to True), which if set to False, will treat the mandatory first argument
as just the string to be matched/or not-matched against the golden input.

2010-09-21 23:33:30 +00:00
Johnny Chen 90312a8492 Wrapped the subclass-specific cleanup call within a try:except: clause.
And removed the informational output from the conditional_break test case.

llvm-svn: 114493
2010-09-21 22:34:45 +00:00
Johnny Chen ea88e94318 Added a more complex test case of breakpoint commands, which executes a sequence
of 'breakpoint command add/list/remove' commands to set breakpoint callbacks,
list them, and then remove one.

Modified the lldbtest.TestBase.expect() method to add two additional keyword
arguments:

o matching (default to True), which, if set to False, reverses the semantics of
  'expect' to 'expect not'

o patterns (default to None), which specifies a list of regexp patterns to match
  against the output from running the command

TestBreakpointCommand.py uses the matching=False and the patterns=[...] expect()
API.

Johnny Chen b330786d1f Added test cases to FoundationTestCase to exercise lookup of objc data types and
to evaluate expressions.  Marked with @expectedFailure decorators for the time
being.

Enhanced the lldbtest.TestBase.expect() API to allow an additional keyword arg
named "error".  If the client passes "error=True", it signifies that an error
while running the command is expected.  The golden input is then compared
against the return object's error output.

Johnny Chen 2fcc0e5555 Added a test case for the settings command which sets process.output-path and
checks that the launched process writes its standard output there.

Johnny Chen 1a9f4dd5a0 Provided a mechanism for the test class to cleanup after itself once it's done.
This will remove the confusion experienced when previous test runs left some
files (both intermediate or by-product as a result of the test).

lldbtest.TestBase defines a classmethod tearDownClass(cls) which invokes the
platform-specific cleanup() function as defined by the plugin; after that, it
invokes a subclass-specific function classCleanup(cls) if defined; and, finally,
it restores the old working directory.

An example of classCleanup(cls) is in settings/TestSettings.py:

    @classmethod
    def classCleanup(cls):
        system(["/bin/sh", "-c", "rm output.txt"])

where it deletes the by-product "output.txt" as a result of running a.out.

2010-09-15 18:00:19 +00:00
Johnny Chen f7f0cabe9f We believed the intermittent process launch failure while running the test suite
has been fixed by r113947.  But just in case it still fails, emits a prominent
message always.

llvm-svn: 113986
2010-09-15 17:33:57 +00:00
Johnny Chen ae74556ff6 Added two test cases to exercise 'expr this->m_c_int' with @expectedFailure
decorators for the time being.

llvm-svn: 113905
2010-09-15 00:00:54 +00:00
Johnny Chen e049051e68 More appropriate headings for the traceoutput: stdout & stderr.
llvm-svn: 113879
2010-09-14 22:39:02 +00:00
Johnny Chen 1aad5c61f8 Removed the expectedFailure decorator from test_with_dwarf_and_run_command() test case
as it now passes.  Added some extra tests to breakpoint_creation_by_filespec_python().

More clarification for the "os command" output and error as defined in
lldbtest.system() function.

Cleaned up the option processing of the test driver (dotest.py) and fixed the comment
about enabling gdb-remote logging.  Example:

$ GDB_REMOTE_LOG=/tmp/log.txt ./dotest.py -v -t enum_types

llvm-svn: 113868
2010-09-14 22:01:40 +00:00
Johnny Chen 1394a4b715 Extend the build mechanism to allow for specifying the compiler used to build
the binaries.

If the build* function is passed the compiler argument, for example, 'llvm-gcc',
it is passed as a make variable to the make command.  Otherwise, we check the
LLDB_CC environment variable; if it is defined, it is passed as a make variable
to the make command.

If neither the compiler keyword argument nor the LLDB_CC environment variable is
specified, no CC make variable is passed to the make command.  The Makefile gets
to define the default CC being used.

--------------------------------------------------------------------------------
Example usage follows:

o Via the keyword argument:

class ArrayTypesTestCase(TestBase):

    mydir = "array_types"

    @unittest2.skipUnless(sys.platform.startswith("darwin"), "requires Darwin")
    def test_with_dsym_and_run_command(self):
        """Test 'frame variable var_name' on some variables with array types."""
        self.buildDsym(compiler='llvm-gcc')
        self.array_types()
...

o Via LLDB_CC environment variable:

$ LLDB_CC=llvm-gcc ./dotest.py -v -t array_types
----------------------------------------------------------------------
Collected 4 tests

test_with_dsym_and_python_api (TestArrayTypes.ArrayTypesTestCase)
Use Python APIs to inspect variables with array types. ... 
os command: [['/bin/sh', '-c', 'make clean; make MAKE_DSYM=YES CC=llvm-gcc']]
output: rm -rf "a.out" "a.out.dSYM"  main.o main.d
llvm-gcc -arch x86_64 -gdwarf-2 -O0 -arch x86_64 -gdwarf-2 -O0  -c -o main.o main.c
llvm-gcc -arch x86_64 -gdwarf-2 -O0  main.o -o "a.out"

Johnny Chen 1b1b9accd1 Marked test_process_launch_for_universal() test case as requiring 'darwin' and 'i386'
in order to be run.  And added a default build phase at the beginning of the method.

2010-09-03 23:49:16 +00:00
Johnny Chen 725945d568 Fixed an lldb infrastructure bug, where the debugger should reaaly update its
execution context only when the process is still alive.  When running the test
suite, the debugger is launching and killing processes constantly.

This might be the cause of the test hang as reported in rdar://problem/8377854,
where the debugger was looping infinitely trying to update a supposedly stale
thread list.

llvm-svn: 113022
2010-09-03 22:35:47 +00:00
Johnny Chen 57b47384cc Added comments regarding the two mechanisms of process cleanup to lldbtest.py.
Also changed the expected strings to be matched since "thread list" changed its
output format.

2010-09-02 22:25:47 +00:00
Johnny Chen 7d1d7537cf Moved the process cleanup of Script-Bridge-based APIs into TestBase.tearDown()
method where they belong.  Also fixed a logic error in maintaining the command
interface flag (runStarted) indicating whether the lldb "run"/"process launch"
command has been issued.  It was erroneously cleared.

Modified the test cases to take advantage of the refactoring.

Johnny Chen 13639089c6 Put the little dances done after SBTarget.LaunchProcess() into the base class.
llvm-svn: 112749
2010-09-01 22:08:51 +00:00
Johnny Chen 63dfb27647 Avoid killing the inferior process twice by passing a setCookie=False keyword
argument when issuing a "run" lldb command within the test case meant to
exercise the Python APIs, but is using the command interface due to certain
reason (such as target.LaunchProcess() does not reliably bring up the inferior).

llvm-svn: 112682
2010-09-01 00:15:19 +00:00
Johnny Chen 8d55a34a34 Changed the buildDsym()/buildDwarf() TestBase methods to use a plugin framework
to delegate the building of binaries to a sys.platform-sepcific plugin.

Modified the dotest.py test driver to add the "plugins" directory to the
PYTHONPATH as well.

darwin.py is the Mac OS X plugin module.

llvm-svn: 112606
2010-08-31 17:42:54 +00:00
Johnny Chen 324355b9a1 Added doc strings to the array_types test cases. And terminate the current
process being debugged in the TestBase.tearDown() instead of letting it continue
and finish.

llvm-svn: 112556
2010-08-30 23:44:39 +00:00
Johnny Chen a33a93cbde Converted TestArrayTypes.py to Dsym/Dwarf combination, and added verbose output
of os command to lldbtest.TestBase.system() method.

llvm-svn: 112547
2010-08-30 23:08:52 +00:00
Johnny Chen 2f1ad5e2bd Added buildDsym() and buildDwarf() methods to lldbtest.TestBase class, and call
them from test cases instead of issuing "make clean; make ..." os command.

llvm-svn: 112542
2010-08-30 22:26:48 +00:00
Johnny Chen 8952a2d5b6 Added a system() method to the TestBase class of lldbtest.py, which is actually
taken from Python 2.7's subprocess.check_output() convenience function.  The
purpose of this method is to run the os command with arguments and return its
output as a byte string.

Modified hello_world/TestHelloWorld.py to have two test cases:

o test_with_dsym_and_run_command
o test_with_dwarf_and_process_launch_api

with the dsym case conditioned on sys.platform.startswith("darwin") being true.
The two cases utilize the system() method to invoke "make clean; make MAKE_DYSM=YES/NO"
to prepare for the appropriate debugging format before running the test logic.

llvm-svn: 112530
2010-08-30 21:35:00 +00:00
Johnny Chen 5ee881948a Added a test case test_breakpoint_creation_by_filespec_python() which creates a
breakpoint by FileSpec and line number and exercises some FileSpec APIs.

Also, RUN_STOPPED is a bad assert name, RUN_SUCCEEDED is better.

llvm-svn: 112327
2010-08-27 23:47:36 +00:00
Johnny Chen 82d404c886 Added TestHelloWorld.py which exercises the Python APIs for target, breakpoint,
and process.  Added comment within the file about issues of using LaunchProcess
of SBTarget to launch a process (rdar://problem/8364687).

llvm-svn: 112276
2010-08-27 18:08:58 +00:00
Johnny Chen 827edffafd Added a test case to bitfields which uses the Python APIs from lldb.py.
Added a utility method to TestBase class to debug print an SBValue object.

llvm-svn: 112247
2010-08-27 00:15:48 +00:00
Johnny Chen 27c412320e Added a utility function EnvArray() to lldbtest.py.
llvm-svn: 112223
2010-08-26 21:49:29 +00:00
Johnny Chen 5fca8ca8cd o Added a test case for array_types which uses the Python APIs from lldb.py,
with the only exception of launching the process from SBTarget which is under
  investigation.

o build-swig-Python.sh should also checks the timestamp of ${swig_input_file}
  for update eligibility.  Also, once an update is in order, there's no need
  to check the remaining header files for timestamps.

o Coaches swig to treat StopReason as an int type, instead of a C++ class.

Johnny Chen 61703c96f2 Minor doc string modification.
llvm-svn: 112103
2010-08-25 22:56:10 +00:00
Johnny Chen f3c59231b3 Added logic to TestUniversal.py to exercise the python APIs:
o SBDebugger.GetCurrentTarget()
o SBTarget.GetProcess()
o SBProcess.GetAddressByteSize()

in order to make sure that, indeed, 64-bit, followed by 32-bit processes have
been launched.

Added invoke() method to TestBase to factor in the tracing logic in one place.
This method allows an object to call a method with no arg reflectively.

llvm-svn: 112102
2010-08-25 22:52:45 +00:00
Johnny Chen 981463d670 Fixed a logic error in the expect() method. If the start string does not match,
there's no point matching further sub strings; the expect() already fails.

Also cleaned up the assert message for VARIABLES_DISPLAYED_CORRECTLY.

llvm-svn: 112074
2010-08-25 19:00:04 +00:00
Johnny Chen f2b70237e6 Allow command retries in case of process launch failures. This recovery
mechanism seems to work fine on my MacBook Pro in some limited test cases.

The default maxLaunchCount and timeWait variables used in the scheme can be
overridden by the env variables LLDB_MAX_LAUNCH_COUNT and LLDB_TIME_WAIT.

Johnny Chen 3c884a014c Added a test for launching a universal binary. Launch of i386 architecture
currently fails: rdar://problem/8349784.

Forgot to check in lldbtest.py in the previous commit r111958.

llvm-svn: 111975
2010-08-24 22:07:56 +00:00
Johnny Chen d0190a6182 Changed the keyword argument for runCmd()/expect() from 'verbose' to 'trace',
which, defaults to False, and if set to True, will trace lldb command execution
and result.

Added "-t" command option to the test driver dotest.py which sets the
LLDB_COMMAND_TRACE environment variable to "YES" and as a result always turns on
command tracing regardless of the 'trace' keyword argument to runCmd()/expect().

llvm-svn: 111811
2010-08-23 17:10:44 +00:00
Johnny Chen ff3d01d0b7 Print the verbose output of runCmd()/expect() to stderr instead of stdout.
