luna-service2

milkcat1994 gihihihi Summary

Open webOS Luna System Bus library, daemon, and utilities

Description

Luna-service2 provides a bus-based IPC mechanism used between components in webOS. Luna-service2 is composed of a client library and a central hub daemon. The client library provides API support to register on the bus and communicate with other components. The hub provides a central clearinghouse for all communication. Utilities for monitoring and debugging the bus are included.

How to Build on Linux

Dependencies

Below are the tools and libraries (and their minimum versions) required to build luna-service2:

  • cmake (version required by webosose/cmake-modules-webos)
  • gcc 4.7.0
  • glib-2.0 2.32.1
  • make (any version)
  • webosose/cmake-modules-webos 1.2.0
  • webosose/libpbnjson 2.13.0
  • webosose/libpbnjson_cpp 2.13.0
  • webosose/PmLogLib 3.0.2
  • pkg-config 0.26

Below are the tools (and their minimum versions) required to test luna-service2:

  • gtest 1.7.0

Building

Once you have downloaded the source, enter the following to build it (after changing into the directory under which it was downloaded):

$ mkdir BUILD
$ cd BUILD
$ cmake ..
$ make
$ sudo make install

The directory under which the files are installed defaults to /usr/local/webos. You can install them elsewhere by supplying a value for WEBOS_INSTALL_ROOT when invoking cmake. For example:

$ cmake -D WEBOS_INSTALL_ROOT:PATH=$HOME/projects/webosose ..
$ make
$ make install

will install the files in subdirectories of $HOME/projects/webosose.

Specifying WEBOS_INSTALL_ROOT also causes pkg-config to look in that tree first before searching the standard locations. You can specify additional directories to be searched prior to this one by setting the PKG_CONFIG_PATH environment variable.

If not specified, WEBOS_INSTALL_ROOT defaults to /usr/local/webos.

To configure for a debug build treating warnings as errors, enter:

$ cmake -D CMAKE_BUILD_TYPE:STRING=Debug -D WEBOS_USE_WERROR:BOOL=TRUE ..

To see a list of the make targets that cmake has generated, enter:

$ make help

Uninstalling

From the directory where you originally ran make install, enter:

$ [sudo] make uninstall

You will need to use sudo if you did not specify WEBOS_INSTALL_ROOT.

Generating Documentation

The tools required to generate the documentation are:

  • doxygen 1.7.6.1
  • graphviz 2.26.3

To generate the documentation, add -D WEBOS_CONFIG_BUILD_DOCS:BOOL=TRUE to the cmake command line and make the docs target:

$ cmake -D WEBOS_CONFIG_BUILD_DOCS:BOOL=TRUE <other-args> ..
$ make docs

To view the generated HTML documentation, point your browser to Documentation/ls2/doc/*/index.html

Testing

To enable tests add -D WEBOS_CONFIG_BUILD_TESTS:BOOL=TRUE to the cmake command line. Add -D WEBOS_GTEST_SRCDIR:STRING=/path/to/gtest to specify path to gtest source directory, default is WEBOS_INSTALL_ROOT/src/gtest.

$ cmake -DWEBOS_CONFIG_BUILD_TESTS=TRUE \
  -DWEBOS_GTEST_SRCDIR=/path/to/gtest <other-args> ..
$ make test

Coverage

To test coverage, add -D WEBOS_USE_GCOV:BOOL=TRUE or -D WEBOS_GCOVR_REPORT:PATH=some_path.txt, where path is previous coverage result. Latter adds coverage target, which requires gcov and gcovr, to collect coverage data.

To get general result, use:

$ make ExperimentalCoverage

To get more detailed gcovr report, place old coverage data at @CMAKE_BUILD_DIR@/some_path.txt and run:

$ make coverage

Or run coverage script directly with optional parameter - previous coverage result. The script will compare current coverage result with the previous one.

$ ./coverage prev_coverage_result.txt

Coverage report is generated every time the script runs at @CMAKE_BUILD_DIR@/coverage_result.txt
