Since the cmake file was made to run on *nix in [1] running the tests with "ctest" broken, because we'd attempt to invoke our bin-wrappers/, but they didn't have the executable bit. In the best case, the "t/test-lib.sh" would be unable to find "bin-wrappers/git", and we'd fall back on "GIT_EXEC_PATH=$GIT_BUILD_DIR" using the fallback behavior added in [2]: $ ./t0001-init.sh <GIT_BUILD_DIR>/t/../contrib/buildsystems/out/bin-wrappers/git is not executable; using GIT_EXEC_PATH This was recently somewhat swept under the rug in [3], as ctest would run them with "--no-bin-wrappers". But still with [3], running e.g.: cmake -S contrib/buildsystems -B contrib/buildsystems/out -DCMAKE_BUILD_TYPE=Debug && make -C contrib/buildsystems/out && ctest --test-dir contrib/buildsystems/out --jobs="$(nproc)" --output-on-failure Fails around 20% of our tests on *nix. So even with [3] we'd fail any test that needed to invoke one of our built shell, perl or Python scripts on *nix. E.g. t0012-help.sh would fail on a test that tried to invoke "git web--browse". The equivalent of this (in the "out" directory) would happen: $ ./git --exec-path=$PWD web--browse git: 'web--browse' is not a git command. See 'git --help'. Which we can fix by "chmod +x"-ing the built "git-web--browse": $ chmod +x git-web--browse $ ./git --exec-path=$PWD web--browse usage: git web--browse [--browser=browser|--tool=browser] [--config=conf.var] url/file ... The same goes for e.g. the "git-p4" tests, which would fail because our built "git-p4" wasn't executable, etc. There's also a few other outstanding issues, which will be fixed in subsequent commits. Ideally we'd use the file(CHMOD ...) form everywhere, but that syntax was introduced in cmake 3.19[4], whereas we only require 3.14. Let's provide a fallback behind a version check, so that we'll eventually be able to delete the "else" part. Both forms result in the same file modes. Before this change: 80% tests passed, 196 tests failed out of 977 After: 99% tests passed, 5 tests failed out of 977 The remaining failures will be addressed in subsequent commits. 1. f31b6244950 (Merge branch 'yw/cmake-updates', 2022-06-07) 2. e4597aae659 (run test suite without dashed git-commands in PATH, 2009-12-02) 3. 2ea1d8b5563 (cmake: make it easier to diagnose regressions in CTest runs, 2022-10-18) 4. https://cmake.org/cmake/help/latest/command/file.html#chmod Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx> write script --- contrib/buildsystems/CMakeLists.txt | 25 +++++++++++++++++++------ 1 file changed, 19 insertions(+), 6 deletions(-) diff --git a/contrib/buildsystems/CMakeLists.txt b/contrib/buildsystems/CMakeLists.txt index a900aff9960..27c939641e0 100644 --- a/contrib/buildsystems/CMakeLists.txt +++ b/contrib/buildsystems/CMakeLists.txt @@ -840,6 +840,19 @@ add_custom_command(OUTPUT ${git_links} ${git_http_links} DEPENDS git git-remote-http) add_custom_target(git-links ALL DEPENDS ${git_links} ${git_http_links}) +function(write_script path content) + file(WRITE ${path} ${content}) + + if("${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}" VERSION_GREATER_EQUAL "3.19") + file(CHMOD ${path} FILE_PERMISSIONS OWNER_READ OWNER_WRITE OWNER_EXECUTE) + else() + execute_process(COMMAND chmod +x ${path} + RESULT_VARIABLE CHILD_ERROR) + if(CHILD_ERROR) + message(FATAL_ERROR "failed to chmod +x '${path}': '${CHILD_ERROR}'") + endif() + endif() +endfunction() #creating required scripts set(SHELL_PATH /bin/sh) @@ -865,7 +878,7 @@ foreach(script ${git_shell_scripts}) string(REPLACE "# @@BROKEN_PATH_FIX@@" "" content "${content}") string(REPLACE "@@PERL@@" "${PERL_PATH}" content "${content}") string(REPLACE "@@PAGER_ENV@@" "LESS=FRX LV=-c" content "${content}") - file(WRITE ${CMAKE_BINARY_DIR}/${script} ${content}) + write_script(${CMAKE_BINARY_DIR}/${script} "${content}") endforeach() #perl scripts @@ -880,13 +893,13 @@ foreach(script ${git_perl_scripts}) file(STRINGS ${CMAKE_SOURCE_DIR}/${script}.perl content NEWLINE_CONSUME) string(REPLACE "#!/usr/bin/perl" "#!/usr/bin/perl\n${perl_header}\n" content "${content}") string(REPLACE "@@GIT_VERSION@@" "${PROJECT_VERSION}" content "${content}") - file(WRITE ${CMAKE_BINARY_DIR}/${script} ${content}) + write_script(${CMAKE_BINARY_DIR}/${script} "${content}") endforeach() #python script file(STRINGS ${CMAKE_SOURCE_DIR}/git-p4.py content NEWLINE_CONSUME) string(REPLACE "#!/usr/bin/env python" "#!/usr/bin/python" content "${content}") -file(WRITE ${CMAKE_BINARY_DIR}/git-p4 ${content}) +write_script(${CMAKE_BINARY_DIR}/git-p4 "${content}") #perl modules file(GLOB_RECURSE perl_modules "${CMAKE_SOURCE_DIR}/perl/*.pm") @@ -1024,20 +1037,20 @@ foreach(script ${wrapper_scripts}) file(STRINGS ${CMAKE_SOURCE_DIR}/wrap-for-bin.sh content NEWLINE_CONSUME) string(REPLACE "@@BUILD_DIR@@" "${CMAKE_BINARY_DIR}" content "${content}") string(REPLACE "@@PROG@@" "${script}${EXE_EXTENSION}" content "${content}") - file(WRITE ${CMAKE_BINARY_DIR}/bin-wrappers/${script} ${content}) + write_script(${CMAKE_BINARY_DIR}/bin-wrappers/${script} "${content}") endforeach() foreach(script ${wrapper_test_scripts}) file(STRINGS ${CMAKE_SOURCE_DIR}/wrap-for-bin.sh content NEWLINE_CONSUME) string(REPLACE "@@BUILD_DIR@@" "${CMAKE_BINARY_DIR}" content "${content}") string(REPLACE "@@PROG@@" "t/helper/${script}${EXE_EXTENSION}" content "${content}") - file(WRITE ${CMAKE_BINARY_DIR}/bin-wrappers/${script} ${content}) + write_script(${CMAKE_BINARY_DIR}/bin-wrappers/${script} "${content}") endforeach() file(STRINGS ${CMAKE_SOURCE_DIR}/wrap-for-bin.sh content NEWLINE_CONSUME) string(REPLACE "@@BUILD_DIR@@" "${CMAKE_BINARY_DIR}" content "${content}") string(REPLACE "@@PROG@@" "git-cvsserver" content "${content}") -file(WRITE ${CMAKE_BINARY_DIR}/bin-wrappers/git-cvsserver ${content}) +write_script(${CMAKE_BINARY_DIR}/bin-wrappers/git-cvsserver "${content}") #options for configuring test options option(PERL_TESTS "Perform tests that use perl" ON) -- 2.38.0.1451.g86b35f4140a
