CTest:Buildserver
Introduction
In a normal CTest installation you have a central repository for your sourcecode. Each client has a special configuration to know how to get the source, build and test it. After finishing the results will be sent to central CDash. This configuration has to be set up at each of the clients. If you create a new branch in your repository and want to get it built by all clients then you must change the configuration at each of the clients.
This solution adds the possibility to manage this in a central place (at the BuildMaster).
How it works
Each BuildSlave asks the BuildMaster for a list of buildnames. Then the BuildSlave downloads a CTestScript.cmake for each buildname and executes it.
Requirements
- CMake/CTest
- wget
- webserver with PHP support
Installation
Buildmaster
Change into your document root directory of your webserver and create a direcotry "CDash", if it does not exesit already. Save the following content as generateCTestScript.php in the CDash direcotory:
@$site = $_GET["site"]; @$build_name = $_GET["buildname"]; // Checks if(!isset($site)) { echo "Not a valid site!"; return; } // THIS CONFIGURATION SHOULD COME FROM THE DATABASE $config_from_database = array( "BUILDSERVER1" => array( "Test1" => array( "@CTS_CMAKE_GENERATOR@" => "Unix Makefiles")), "BUILDSERVER2" => array( "Test1" => array( "@CTS_CMAKE_GENERATOR@" => "Unix Makefiles")), "BUILDSERVER3" => array( "Test1" => array( "@CTS_CMAKE_GENERATOR@" => "NMake Makefiles"), "Test2" => array( "@CTS_CMAKE_GENERATOR@" => "NMake Makefiles", "@CTS_REPOSITORY_URL@" => "http://VERSIONCONTROL/svn/test2/trunk"), "Test3" => array( "@CTS_CMAKE_GENERATOR@" => "NMake Makefiles", "@CTS_REPOSITORY_URL@" => "http://VERSIONCONTROL/svn/test3/branches/next_release")), "BUILDSERVER4" => array( "Test1" => array( "@CTS_CMAKE_GENERATOR@" => "NMake Makefiles"))); // no build given, so Generate overviewlist if(!isset($build_name)) { $list = array_keys($config_from_database[$site]); header('Content-Type: text/plain'); echo implode("\n", $list); return; } // DEFAULT SETTINGS $script_parameter = array( "@CTS_SITE@" => $site, "@CTS_PROJECT_NAME@" => "Test", "@CTS_BUILD_NAME@" => $build_name, "@CTS_NIGHTLY_START_TIME@" => "22:00:00 UTC", "@CTS_CMAKE_GENERATOR@" => "Unix Makefiles", "@CTS_BUILD_CONFIGURATION@" => "Release", "@CTS_CTEST_MODEL@" => "Continuous", "@CTS_BUILD_OPTIONS@" => "-DEXAMPLE_OPTION=1", "@CTS_REPOSITORY_URL@" => "http://VERSIONCONTROL/svn/test1"); // template.txt SHOULD ALSO COME FROM THE DATABASE $ctestscript = strtr(strtr(implode(file("template.txt")), $config_from_database[$site][$build_name]), $script_parameter); header('Vary: User-Agent'); if(ob_get_contents()) echo "Some data has already been output"; if(isset($_SERVER['HTTP_USER_AGENT']) && strpos($_SERVER['HTTP_USER_AGENT'],'MSIE')) header('Content-Type: application/force-download'); else header('Content-Type: application/octet-stream'); if(headers_sent()) echo "Some data has already been output to browser"; header("Content-Disposition: attachment; filename=\"CTestScript.cmake\""); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".strlen($ctestscript)); echo $ctestscript; ?>
The following is an example for the template.txt, which also does a upload of a generated NSIS setup:
set(CTEST_SITE "@CTS_SITE@") set(CTEST_PROJECT_NAME "@CTS_PROJECT_NAME@") set(CTEST_BUILD_NAME "@CTS_BUILD_NAME@") set(CTEST_NIGHTLY_START_TIME "@CTS_NIGHTLY_START_TIME@") set(CTEST_CMAKE_GENERATOR "@CTS_CMAKE_GENERATOR@") set(CTEST_BUILD_CONFIGURATION "@CTS_BUILD_CONFIGURATION@") set(MODEL "@CTS_CTEST_MODEL@") set(BUILD_OPTIONS "@CTS_BUILD_OPTIONS@") set(REPOSITORY_URL "@CTS_REPOSITORY_URL@") find_package(Subversion) set(CTEST_SOURCE_DIRECTORY "${CTEST_SCRIPT_DIRECTORY}/source") set(CTEST_BINARY_DIRECTORY "${CTEST_SCRIPT_DIRECTORY}/build") set(CTEST_UPDATE_COMMAND ${Subversion_SVN_EXECUTABLE}) if(NOT DEFINED CTEST_DROP_METHOD) set(CTEST_DROP_METHOD "http") endif() if(CTEST_DROP_METHOD STREQUAL "http") set(CTEST_DROP_SITE "BUILDMASTER") set(CTEST_DROP_LOCATION "/CDash/submit.php?project=${CTEST_PROJECT_NAME}") set(CTEST_DROP_BUILD_LOCATION "/CDash/uploadbuild.php?project=${CTEST_PROJECT_NAME}") set(CTEST_TRIGGER_SITE "") endif() string(COMPARE NOTEQUAL "${MODEL}" "Continuous" SUBMIT_ALWAYS) set(NEED_REPOSITORY_CHECKOUT 1) if(EXISTS "${CTEST_SOURCE_DIRECTORY}") subversion_wc_info("${CTEST_SOURCE_DIRECTORY}" REPOSITORY) string(COMPARE NOTEQUAL "${REPOSITORY_URL}" "${REPOSITORY_WC_URL}" NEED_REPOSITORY_CHECKOUT) if(${NEED_REPOSITORY_CHECKOUT}) file(REMOVE_RECURSE "${CTEST_SOURCE_DIRECTORY}") endif() else() set(NEED_REPOSITORY_CHECKOUT 1) endif() if(${NEED_REPOSITORY_CHECKOUT}) set(CTEST_CHECKOUT_COMMAND "${CTEST_UPDATE_COMMAND} co ${REPOSITORY_URL} \"${CTEST_SOURCE_DIRECTORY}\" -r HEAD") else() set(CTEST_CHECKOUT_COMMAND "${CTEST_UPDATE_COMMAND} update") endif() set(CTEST_CONFIGURE_COMMAND "${CMAKE_COMMAND} -DCMAKE_BUILD_TYPE=${CTEST_BUILD_CONFIGURATION} ${BUILD_OPTIONS} \"-G${CTEST_CMAKE_GENERATOR}\" \"${CTEST_SOURCE_DIRECTORY}\"") ctest_start(${MODEL}) if(${CTEST_SCRIPT_ARG} MATCHES ${MODEL}) ctest_update(SOURCE "${CTEST_SOURCE_DIRECTORY}" RETURN_VALUE NUMBER_FILES) if(${SUBMIT_ALWAYS} OR ${NEED_REPOSITORY_CHECKOUT} OR ${NUMBER_FILES} GREATER 0) ctest_configure(BUILD "${CTEST_BINARY_DIRECTORY}") ctest_build(BUILD "${CTEST_BINARY_DIRECTORY}") ctest_test(BUILD "${CTEST_BINARY_DIRECTORY}") ctest_submit() execute_process(COMMAND "cpack" WORKING_DIRECTORY ${CTEST_BINARY_DIRECTORY} RESULT_VARIABLE cpackResult OUTPUT_VARIABLE cpackLog ERROR_VARIABLE cpackLog) file(WRITE ${CTEST_BINARY_DIRECTORY}/Testing/cpack.log "${cpackLog}") file(GLOB UPLOAD_FILES "build/*.deb" "build/*.exe") foreach(_currentArg ${UPLOAD_FILES}) get_filename_component(_fn ${_currentArg} NAME) execute_process(COMMAND wget "${CTEST_DROP_METHOD}://${CTEST_DROP_SITE}${CTEST_DROP_BUILD_LOCATION}&fn=${_fn}" "--post-file=${_currentArg}" "-o${CTEST_BINARY_DIRECTORY}/Testing/upload.log" "-q") file(REMOVE "${CTEST_BINARY_DIRECTORY}/${_currentArg}") endforeach() endif() endif()
Linux BuildSlave
Create a a directory "/var/builds" and save the following shell script as make.sh in this directory
cd /var/builds site=BUILDSLAVE1 wget http://BUILDMASTER/CDash/generateCTestScript.php?site=$site\&buildtype=$1 -O list.txt -q for d in $(ls -d */); do SKIP_DELETE=0 for p in $(cat list.txt); do if [ $p = ${d%%/} ]; then SKIP_DELETE=1 fi done if [ $SKIP_DELETE = 0 ]; then rm -r ${d%%/} fi done for p in $(cat list.txt); do if [ ! -d $p ]; then mkdir $p fi if [ ! -e $p.lock ]; then touch $p.lock cd $p wget http://BUILDMASTER/CDash/generateCTestScript.php?site=$site\&buildname=$p -O CTestScript.cmake -q ctest -S CTestScript.cmake,$1 cd .. rm -f $p.lock fi done rm list.txt
Finaly you have to create a cron job (see CTest Scripting) for each buildtype (Nightly, Continuous), which will execute this shell script:
- For a nightly build create a job to execute "/var/builds/make.sh Nightly" at your CTEST_NIGHTLY_START_TIME.
- To setup a continuous build create a job, which will execute "/var/builds/make.sh Continuous" every minute.
Windows BuildSlave
Create a a directory "C:\builds" and save the following batch script as make.bat in this directory
@echo off set site=BUILDSLAVE3 call "C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\vcvars32.bat" if not exist %1 mkdir %1 pushd %1 wget http://BUILDMASTER/CDash/generateCTestScript.php?site=%site%^&buildtype=%1 -O list.txt -q for /D %%d in (*) do ( if exist skip_delete.flag del skip_delete.flag for /f %%p in (list.txt) do ( if %%p == %%d echo 0 > skip_delete.flag ) if not exist skip_delete.flag rmdir /S /Q %%d ) if exist skip_delete.flag del skip_delete.flag for /f %%p in (list.txt) do ( if not exist %%p mkdir %%p if not exist %%p.lock ( echo 0 > %%p.lock pushd %%p wget http://BUILDMASTER/CDash/generateCTestScript.php?site=%site%^&buildname=%%p -O CTestScript.cmake -q ctest -S CTestScript.cmake,%1 popd del %%p.lock ) ) del list.txt popd
Finaly you have to create a sheduled task (see CTest Scripting) for each buildtype (Nightly, Continuous), which will execute this batch file:
- For a nightly build create a task to execute "C:\builds\make.bat Nightly" at your CTEST_NIGHTLY_START_TIME.
- To setup a continuous build create a task, which will execute "C:\builds\make.bat Continuous" every minute.
