Revision as of 19:58, 2 August 2011
Rationale
One of the "coding" tasks consisted of actually going through our Find*.cmake files in kdelibs and its siblings and check what could be removed, upstreamed or merged in the future.
The following tables look not only at the Find files, but also at some helper CMake files which may also cease to exist or move together with their Find counterparts.
kdelibs, kdepimlibs, kde-baseapps, kde-runtime and kde-workspace were analysed.
Check*.cmake files
| File Name | Exists in CMake | Plan | Comments | Style | Status | Who |
| CheckCXXSourceCompiles.cmake | Yes | Upstream to ECM, merge in changes from CMake | Our version supports linking against imported targets, upstream CMake doesn't. Search mailing list for CMake developers' rationale, maybe upstream. Began to diverge; CMake has FAIL_REGEX support, our version handles imported targets (Alex said CMake developers did not accept this feature upstream, need to search the mailing list archives). | Ok | Decided | ? |
| CheckCXXSourceRuns.cmake | Yes | See above. | See above | Ok | Decided | ? |
| CheckCXXSymbolExists.cmake | No | Upstream to CMake | Either check if we still support glibc 2.9, perhaps try upstreaming. Almost equivalent to CMake's CheckSymbolExists.cmake, just creates .cxx files instead of .c ones. | Ok | DONE | Alex |
| CheckPointerMember.cmake | No | Upstream to CMake (or ECM) | Only used by krdc. Calls check_cxx_source_compiles on a struct with a given member. | Ok | Need feedback. | ? |
| CheckPrototypeExists.cmake | No | Upstream to CMake (or ECM) | 1d0e1a0 says this was going to be upstreamed. Try again? | Ok | Need feedback | ? |
| CheckStructMember.cmake | No | Remove | CMake has CheckStructHasMember.cmake, but out version uses a C++ compiler for checking. Simply remove or add a CheckCXXStructHasMember.cmake to CMake ? Where is it used where C++ is needed ? | - | Need feedback | - |
Generic Macros
| File Name | Exists in CMake | Plan | Comments | Style | Status | Who |
| MacroAddCompileFlags.cmake | No | Remove | A trivial macro, used only in few places (kdm mainly I think). Use set_property(APPEND_STRING) instead | - | DONE | Alex |
| MacroAddLinkFlags.cmake | No | Remove | A trivial macro, used only in few places (kdm mainly I think).Use set_property(APPEND_STRING) instead | - | DONE | Alex |
| MacroAdditionalCleanFiles.cmake | No | Remove | Use set_property(DIRECTORY APPEND PROPERTY ADDITIONAL_MAKE_CLEAN_FILES file1 ... ) instead | - | DONE | Alex |
| MacroAppendIf.cmake | No | Remove | Not used anywhere. (Raphael) Really ? (Alex) | Ok | Need feedback | ? |
| MacroBoolTo01.cmake | No | Upstream to ECM | Ok | Need feedback | ? | |
| MacroEnsureOutOfSourceBuild.cmake | No | Upstream to CMake (or ECM) | Many people request something like this on the cmake list. | Ok | Need feedback | ? |
| MacroEnsureVersion.cmake | No | Upstream? to ECM ? Or Remove ? | It doesn't do much more than if(... VERSION_GREATER ...) . This was not available yet in 2007 when the macro was written. | Ok | Need feedback | ? |
| MacroKAuth.cmake | No | Remove. | Already deprecated. | - | DONE | Alex |
| MacroLibrary.cmake | No | Upstream to ECM | The idea of this file is that it simply includes all macro files so as user you have to include only this one file and get all macro from ECM. | Ok | Need feedback. | ? |
| MacroLogFeature.cmake | No | Remove and extend CMake's FeatureSummary as necessary. | Investigate CMake's FeatureSummary, what needs to be added so that MacroLogFeature becomes unnecessary. This requires some real work. | Ok | DONE | Alex |
| MacroOptionalAddSubdirectory.cmake | No | Upstream to ECM | Will not be accepted into CMake | Ok | DONE | Alex |
| MacroOptionalDependPackage.cmake | No | Remove | Broken, expects a FindFoo.cmake possibly provided by the application itself. | - | DONE | Alex |
| MacroOptionalFindPackage.cmake | No | Remove | in CMake 2.8.6 each find_package() call can be disabled via CMAKE_DISABLE_FIND_PACKAGE_PackageName. | - | DONE | Alex |
| MacroPushRequiredVars.cmake | No | Upstream to CMake | Useful when testing for stuff using check_function_exists() etc. Renamed to cmake_push/pop_check_state() | Ok | DONE | Alex |
| MacroWriteBasicCMakeVersionFile.cmake and BasicFindPackageVersion.cmake.in | No | Upstream to CMake (or ECM) | Useful for every package which installs a FooConfig.cmake file | Ok | Decided | Alex |
KDE specific stuff
In this table, files are listed which are mostly KDE4-specific and which belong to KDE. Still some of them might be candidates for upstreaming.
| File Name | Plan | Comments | Style | Status | Who |
| FindKDE4Internal.cmake | Keep in kdelibs, but mostly replace with installed FooConfig.cmake files | The FooConfig.cmake files feature did not exist when we started to use cmake for KDE. If it would have already existed back then, this file wouldn't exist in the form as it is today. | Ok | Need feedback | ? |
| KDE4Macros.cmake | Keep in kdelibs | Will be included from the installed Config.cmake file | Ok | Need feedback | ? |
| Win32Macros.cmake | Keep, refactor/rename. | Used by KDE4Macros.cmake under Windows. It contains currently exactly one macro, so the name is misleading. | So-so | Need feedback | ? |
| kde4init_dummy.cpp.in and kde4init_win32lib_dummy.cpp.in | Keep in kdelibs | Used by KDE4Macros.cmake. Necessary for kdeinit support | Ok | Decided | - |
| kde4_exec_via_sh.cmake | Keep in kdelibs | Used by KDE4Macros.cmake | Ok | Decided. | - |
| kde4uic.cmake | Keep in kdelibs or remove | Still necessary with Qt5 ? | Ok | Need feedback | ? |
| KDE4Defaults.cmake | Keep in kdelibs | Ok | Need feedback | ? | - |
| kde4automoc.files.in | Remove | This file is unused, it is already in automoc in kdesupport | - | Decided | - |
| kde4_cmake_uninstall.cmake.in | Upstream to CMake (or ECM) | This is used to automatically create an uninstall target. Currently done by FindKDE4Internal.cmake. This could be made into a macro in ECM, which is called by FindKDE4Internal.cmake | Ok | Need feedback | ? |
| check_installed_exports_file.cmake | ? | Have to check. Looks like keep or upstream. I think the issue mentioned in the file is still valid. | Ok | Need feedback | ? |
| kde4exportsheader.h.in | Upstream to CMake (or ECM) | Used in KDE4Macros.cmake | Ok | In Progress | Stephen |
Find*.cmake
In this table, "upstreaming" a module can mean sending it to either CMake itself or the external modules collection.
kdelibs
Exist in cmake
All the following modules should be synced with CMake, so we can remove our own copies.
We have to make sure that
- all features of the version from CMake are kept
- the module from CMake stays 100% source compatible
- probably also all features from our version are kept
- source compatibility for our version may be broken, but must be documented here: http://techbase.kde.org/Development/ECM_SourceIncompatChanges
| File Name | Comments | Status | Who |
| FindBoost.cmake | Remove. Already deprecated. | TODO | ? (not me, Alex) |
| FindFreetype.cmake | Merge or remove. | TODO | Alex |
| FindGIF.cmake | Probably remove. | TODO | Alex |
| FindGettext.cmake | Merge or provide our macros separately. We have some macros used in release tarballs. | TODO | ? |
| FindLibXml2.cmake | Remove. Upstream is identical. | DONE | Alex |
| FindLibXslt.cmake | Our version has some more features. Merge them into the cmake version, then remove our version. | TODO | Alex |
| FindOpenSSL.cmake | Remove. Upstream is pretty much identical, should even solve some reported build issues. | TODO | ? (not me, Alex) |
| FindPackageHandleStandardArgs.cmake | Remove once we depend on 2.8.4 | DONE | Alex |
| FindPkgConfig.cmake | Remove, upstream is identical. | DONE | Alex |
| FindPostgreSQL.cmake | Probably remove. Upstream looks more complete. | TODO | ? |
| FindPythonLibrary.cmake | CMake has FindPythonInterp.cmake and FindPythonLibs.cmake. Try to merge with CMake. | TODO | ? (not me, Alex) |
| FindQt4.cmake, Qt4Macros.cmake and Qt4ConfigDependentSettings.cmake | Sync with CMake 2.8.6, then remove our copy. We may need to keep a copy because we often need newest Qt but don't want to depend on newest CMake all the time. But with Qt5 FindQt4 will be obsolete anyway. | TODO | ? |
| FindRUBY.cmake | CMake has FindRuby.cmake.Remove our copy | DONE | Alex |
| FindX11.cmake | Remove. It has some small differences to the one in cmake AFAIK. | TODO | ? |
