osex3basicTest

tester for HUJI OS 2020 exercise 3

Instructions:

  1. Clone this repository under the mattanTests directory by using the following command:

    cd YOUR_PROJECT_ROOT_FOLDER
git clone https://github.com/mattany/osex3basicTest mattanTests

  2. Use the following CMakeLists.txt in your project root. Add your own source files as needed at row 26

    cmake_minimum_required(VERSION 3.1)


# NOTE: You can't have both ThreadSanitizer and AddressSanitizer enabled at the same time.

# Uncomment the following to enable ThreadSanitizer.
#set (CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -fno-omit-frame-pointer -fsanitize=thread")
#set (CMAKE_LINKER_FLAGS_DEBUG "${CMAKE_LINKER_FLAGS_DEBUG} -fno-omit-frame-pointer -fsanitize=thread")

# Uncomment the following to enable AddressSanitizer.
#set (CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -fno-omit-frame-pointer -fsanitize=address")
#set (CMAKE_LINKER_FLAGS_DEBUG "${CMAKE_LINKER_FLAGS_DEBUG} -fno-omit-frame-pointer -fsanitize=address")


# Project configuration
project(ex3 VERSION 1.0 LANGUAGES C CXX)


# Ensure system has pthreads
set(THREADS_PREFER_PTHREAD_FLAG ON)
find_package(Threads REQUIRED)

add_library(MapReduceFramework
        MapReduceClient.h
        MapReduceFramework.cpp MapReduceFramework.h
# ------------- Add your own .h/.cpp files here -------------------
)


set_property(TARGET MapReduceFramework PROPERTY CXX_STANDARD 11)
target_compile_options(MapReduceFramework PUBLIC -Wall -Wextra)
target_include_directories(MapReduceFramework PUBLIC ${CMAKE_CURRENT_SOURCE_DIR})
# link pthreads to your framework
target_link_libraries(MapReduceFramework PUBLIC Threads::Threads)

# Add tests
add_subdirectory(mattanTests)

    Note, do not change 'MapReduceFramework' anywhere in the above template.

    You can enable Address Sanitizer or Thread Sanitizer(only one of them), but you will fail the test errorMessageTest. Other tests should pass with NO MEMORY LEAKS.

    Valgrind is not recommended, prefer using ASan as it is much faser.

    It is recommended that you also test your program with high optimization levels, by adding -O2 to target_compile_options, and to delete print statements in your code(if you have any), as well as asserts (by using -DNDEBUG flag), as these things affect the program's behavior and can uncover multi-threading bugs.

  3. If using CLion, reload the cmake project(under File) after doing the above, then compile(Build | Build 'All') Now, you can run individual tests by going to the tests source code (YOUR_PROJECT_ROOT/mattanTests/SampleClient.cpp), and there's a green button near each test(TEST(...)) that allows you to run/debug it. Alternatively, right click on the entire file and you can do Run 'All in SampleClient...' to run all tests at once.

    If using terminal, do the following to compile and run. It is important that you delete the cmake-build-debug whenever you change to a different system, but otherwise it is not needed.

    Compile:

    cd YOUR_PROJECT_ROOT
rm -rf cmake-build-debug
mkdir cmake-build-debug
cd cmake-build-debug
cmake ..
make -j 4

    And run via YOUR_PROJECT_ROOT/cmake-build-debug/mattanTests/mattanTester --gtest_filter="-*error*" (without 'errorMessageTest', supports ASan/TSan), omit the gtest_filter to run the errorMessageTest too, but note that it will fail if you have a sanitizer enabled in your CMakeLists.
