Hi, I'd like to downport the support for Visual Studio Code project creation to 11u. I think we will have to support 11u for quite some years and it makes sense to have as good as possible tool support in 11u as well.
This mail is especially intended to get a review from the build team that the few changes to the patches are OK: https://bugs.openjdk.java.net/browse/JDK-8210459 http://cr.openjdk.java.net/~simonis/webrevs/2019/8210459/ https://bugs.openjdk.java.net/browse/JDK-8218807 http://cr.openjdk.java.net/~simonis/webrevs/2019/8218807/ https://bugs.openjdk.java.net/browse/JDK-8223678 http://cr.openjdk.java.net/~simonis/webrevs/2019/8223678/ The downport consists of three changes which are additive (i.e. later changes depend on earlier ones). That's why I decided to post just one RFR, because looking at a single change makes no sense without the corresponding context. The changes mostly apply cleanly except for very few places where we need manual adjustments because of changed context. These changes only touch make files and actually only add new features to the make system, so the normal build results shouldn't be affected. I've tested that the build still works on Linux and Windows and "make test-make" succeeds. Following some details on the three changes: 8210459: Add support for generating compile_commands.json The initial change which creates the compile_commands.json file (i.e. "make compile_commands"). This file can be used for many tools (e.g. CLion IDE, clangd, etc..) Applies cleanly except for the following hunk, which has a different context: ORIGINAL ======== CFLAGS_solaris := -KPIC, \ CFLAGS_macosx := -fPIC, \ DISABLED_WARNINGS_clang := format-nonliteral, \ - LDFLAGS := $(UNPACKEXE_ZIPOBJS) \ - $(LDFLAGS_JDKEXE) $(LDFLAGS_CXX_JDK) \ + LDFLAGS := $(LDFLAGS_JDKEXE) $(LDFLAGS_CXX_JDK) \ JDK11u ====== CFLAGS_linux := -fPIC, \ CFLAGS_solaris := -KPIC, \ CFLAGS_macosx := -fPIC, \ - LDFLAGS := $(UNPACKEXE_ZIPOBJS) \ - $(LDFLAGS_JDKEXE) $(LDFLAGS_CXX_JDK) \ + LDFLAGS := $(LDFLAGS_JDKEXE) $(LDFLAGS_CXX_JDK) \ 8218807: Compilation database (compile_commands.json) may contain obsolete items This is a simple fix for 8210459 and applies cleanly 8223678: Add Visual Studio Code workspace generation support (for native code) This change actually creates the VS Code project files (i.e. "make vscode-project-ccls"). See http://hg.openjdk.java.net/jdk/jdk/raw-file/tip/doc/ide.html for more details. Applies cleanly except the following two hunks. The first one had to be moved back from "make/common/Utils.gmk" to "make/common/MakeBase.gmk" where it still applies cleanly, because the "RelativePath" macro is still in "MakeBase.gmk" in jdk11u.

These tests are currently broken in jdk11u. They have been broken by JDK-8212028 (which has already been downported to jdk11u) and fixed in jdk 12 as part of "8210958: Rename "make run-test" to "make test"" (which hasn't been downported yet and probably won't be donwported at all). Because the fix is trivial (that's why it was done as part of 8210958 without an extra bug ID) and because I wanted to run "make test-make" in jdk11u as well to verify my changes, I've decided to downport this fix as part of 8223678: diff -r 8599975f5b33 test/make/TestMakeBase.gmk --- a/test/make/TestMakeBase.gmk Tue Feb 12 08:40:43 2019 +0100 +++ b/test/make/TestMakeBase.gmk Mon Dec 23 22:10:46 2019 +0100 KWBASE := APA=banan;GURKA=tomat;COUNT=1%202%203%204%205;SUM=1+2+3+4+5;MANY_WORDS=I have the best words. $(eval $(call ParseKeywordVariable, KWBASE, \ - KEYWORDS := APA GURKA SUM, \ + SINGLE_KEYWORDS := APA GURKA SUM, \ STRING_KEYWORDS := COUNT MANY_WORDS, \ )) @@ -364,7 +376,7 @@ KWBASE_WEIRD := ;;APA=banan;;;GURKA=apelsin;APA=skansen;; $(eval $(call ParseKeywordVariable, KWBASE_WEIRD, \ - KEYWORDS := APA GURKA SUM, \ + SINGLE_KEYWORDS := APA GURKA SUM, \ STRING_KEYWORDS := COUNT, \ ))
