2015-10-28Move lldb/test to lldb/packages/Python/lldbsuite/test.Zachary Turner
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`). llvm-svn: 251532

2015-10-26Port the python api decorator to use test categoriesPavel Labath
Summary: Per discussions on the mailing list, I have implemented a decorator which annotates individual test methods with categories. I have used this framework to replace the '-a' and '+a' command-line switches (now '-G pyapi' and '--skip-category pyapi') and the @python_api_test decorator (now @add_test_categories('pyapi')). The test suite now gives an error message suggesting the new options if the user specifies the deprecated +/-a switches. If the general direction is good, I will follow this up with other switches.

2015-10-23Add from __future__ import print_function everywhere.Zachary Turner
Apparently there were tons of instances I missed last time, I guess I accidentally ran 2to3 non-recursively. This should be every occurrence of a print statement fixed to use a print function as well as from __future__ import print_function being added to every file. After this patch print statements will stop working everywhere in the test suite, and the print function should be used instead. llvm-svn: 251121
2015-10-22Update every test to import `lldb_shared`.Zachary Turner
This is necessary in order to allow third party modules to be located under lldb/third_party rather than under the test folder directly. Since we're already touching every test file anyway, we also go ahead and delete the unittest2 import and main block wherever possible. The ability to run a test as a standalone file has already been broken for some time, and if we decide we want this back, we should use unittest instead of unittest2. A few places could not have the import of unittest2 removed,because they depend on the unittest2.expectedFailure or skip decorators. Removing all those was orthogonal in spirit to the purpose of this CL, so the import of unittest2 remains in those files that were using it for its test decorators. Those can be addressed separately. llvm-svn: 251055
2015-09-30Merge dwarf and dsym testsTamas Berghammer
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 Differential revision: http://reviews.llvm.org/D13028 llvm-svn: 248883

2015-07-16Add a class ValueObjectConstResultCast.Siva Chandra
Summary: Other changes around the main change include: 1. Add a method Cast to ValueObjectConstResult, ValueObjectConstResultImpl and ValueObjectConstResultChild. 2. Add an argument |live_address| of type lldb::addr_t to the constructor of ValueObjectConstResultChild. This is passed on to the backing ValueObjectConstResultImpl object constructor so that the address of the child value can be calculated properly.

2015-03-12Avoid a failing test case by fixing things so the compiler generates a line ↵Greg Clayton
table entry for line the very start of the printf() before any values have been loaded into registers. The issue was the previous code tried to stop on the following code in main.c: 21 // Stop here and set values 22 printf ("Val - %d Mine - %d, %d, %llu. Ptr - %d, %d, %llu\n", 23 val, 24 mine.first_val, mine.second_val, mine.third_val, 25 ptr->first_val, ptr->second_val, ptr->third_val); We we set a source regex breakpoint on "// Stop here and set values" we would set a breakpoint on line 22 as expected. The problem is the most recent clang compiler generates a line table like this 0x1000: main.c:23 // Loading of "val" into a register 0x1010: main.c:24 // Load mine.first_val, mine.second_val, mine.third_val values into registers or on the stack 0x1020: main.c:25 // Load ptr->first_val, ptr->second_val, ptr->third_val values into registers or on the stack 0x1030: main.c:22 // Call to printf In this test, we run to line 22, then we use python to modify the value of "val" and then continue to another breakpoint and try to read the STDOUT from the printf to verify the values changed correctly. With the above line table the value for "val" had already been loaded into a register so the string from printf would be incorrect. Doing an easy fix for now by changing the code to: 21 // Stop here and set values 22 printf ("Val - %d Mine - %d, %d, %llu. Ptr - %d, %d, %llu\n", val, 23 mine.first_val, mine.second_val, mine.third_val, 24 ptr->first_val, ptr->second_val, ptr->third_val); Now we get a line table entry for line 22 that is before any locals are read from the stack into registers. I need to follow up with the compiler guys and see if we can get a fix for this as anyone setting file + line breeakpoints might be very surprised to have code from lines below the current line already have had their code run. llvm-svn: 232068

2011-07-26The test function to determine whether we have reached the end of the list wasJohnny Chen
too complex in the test case. We can just simply test that the SBValue object is a valid object and it does not correspond to a null pointer in order to say that EOL has not been reached. Modify the test case and the lldb.py docstring to have a more compact test function. llvm-svn: 136123

2011-07-25Provide an add-on API to SBValue class by post-processing to provide a wayJohnny Chen
to iterate through an SBValue instance by treating it as the head of a linked list. API program must provide two args to the linked_list_iter() method: the first being the child member name which points to the next item on the list and the second being a Python function which an SBValue (for the next item) and returns True if end of list is reached, otherwise it returns False. For example, suppose we have the following sample program. #include <stdio.h> class Task { public: int id; Task *next; Task(int i, Task *n): id(i), next(n) {} }; int main (int argc, char const *argv[]) { Task *task_head = new Task(-1, NULL); Task *task1 = new Task(1, NULL); Task *task2 = new Task(2, NULL); Task *task3 = new Task(3, NULL); // Orphaned. Task *task4 = new Task(4, NULL); Task *task5 = new Task(5, NULL); task_head->next = task1; task1->next = task2; task2->next = task4; task4->next = task5; int total = 0; // Break at this line Task *t = task_head; while (t != NULL) { if (t->id >= 0) ++total; t = t->next; } printf("We have a total number of %d tasks\n", total); return 0; } The test program produces the following output while exercising the linked_list_iter() SBVAlue API: task_head: TypeName -> Task * ByteSize -> 8 NumChildren -> 2 Value -> 0x0000000106400380 ValueType -> local_variable Summary -> None IsPointerType -> True Location -> 0x00007fff65f06e60 (Task *) next = 0x0000000106400390 (int) id = 1 (Task *) next = 0x00000001064003a0 (Task *) next = 0x00000001064003a0 (int) id = 2 (Task *) next = 0x00000001064003c0 (Task *) next = 0x00000001064003c0 (int) id = 4 (Task *) next = 0x00000001064003d0 (Task *) next = 0x00000001064003d0 (int) id = 5 (Task *) next = 0x0000000000000000 llvm-svn: 135938
