Minor cosmetic update for manual docbook #5

vBm · 2010-12-13T14:17:22Z

Few minor cosmetic changes that i think should be made. Your call if they end up in master or not.

The following code causes cppcheck execution to hang: void f1() { if (1) new X * [0](); else new Y * [0](); } void f2() { for (int i = 0;; i++) ; } When analyzing the hang with GDB, the following can be seen: (gdb) bt #0 0x00000000008eff0b in Token::astTop (this=0xc3c060) at lib/token.h:881 #1 0x00000000008ef7ec in createAstAtToken (tok=0xc3b930, cpp=0x1) at lib/tokenlist.cpp:949 danmar#2 0x00000000008efd3c in TokenList::createAst (this=0x7fffffffbf00) at lib/tokenlist.cpp:1004 danmar#3 0x000000000089c234 in Tokenizer::tokenize (this=0x7fffffffbf00, code=..., FileName=0xc36038 "temp.cc", configuration="", noSymbolDB_AST=0x0) at lib/tokenize.cpp:1728 danmar#4 0x00000000007c8b62 in CppCheck::checkFile (this=0x7fffffffcf50, code="void f1()\n{\nif (1)\nnew X * [0]();\nelse\nnew Y * [0]();\n}\n\nvoid f2()\n{\nfor (int i = 0;; i++) ;\n}\n", FileName=0xc36038 "temp.cc", checksums=std::__debug::set with 0 elements, internalErrorFound=@0x7fffffffc46b: 0x0) at lib/cppcheck.cpp:337 danmar#5 0x00000000007c78da in CppCheck::processFile (this=0x7fffffffcf50, filename="temp.cc", fileStream=...) at lib/cppcheck.cpp:239 danmar#6 0x00000000007c6348 in CppCheck::check (this=0x7fffffffcf50, path="temp.cc") at lib/cppcheck.cpp:70 danmar#7 0x00000000006a51ef in CppCheckExecutor::check_internal (this=0x7fffffffd9f0, cppcheck=..., argv=0x7fffffffdba8) at cli/cppcheckexecutor.cpp:810 danmar#8 0x00000000006a3d7b in CppCheckExecutor::check (this=0x7fffffffd9f0, argc=0x2, argv=0x7fffffffdba8) at cli/cppcheckexecutor.cpp:183 danmar#9 0x00000000006ac591 in main (argc=0x2, argv=0x7fffffffdba8) at cli/main.cpp:136 The code in question is (lib/token.h:881): const Token *astTop() const { const Token *ret = this; while (ret->_astParent) ret = ret->_astParent; return ret; } It looks like there is some kind of loop in AST: (gdb) p ret (gdb) p ret->_astParent $2 = (Token *) 0xc3ba10 (gdb) p ret->_astParent->_astParent $3 = (Token *) 0xc3be70 (gdb) p ret->_astParent->_astParent->_astParent $4 = (Token *) 0xc3ba10 Using Git bisect revealed that the following commit introduced the problem: ca1f19b This commit adds a testcase that reveals this problem. I.e. when running "make test", the execution hangs.

* Better handle const/noexcept methods/conversion operator const or noexcept in a method / (conversion) operator definition were badly parsed, ending in a bad ast.
