en Copyright 2015 Java http://172.16.0.5:8080/history/llvm-project-15.0.7/lldb/test/API/iohandler/completion/Makefile#ffcf5711 [LLDB] Fix 'std::out_of_range' crashing bug when file name completion using file path.When I run a lldb command that uses filename completion, if I enter a stringthat is not only a filename but also a string with a non-file name string added,such as "./" that is relative path string , it will crash as soon as I press the[Tab] key. For example, debugging an executable file named "hello" that iscompiled from a file named "hello.c" , and I’ll put a breakpoint on line 3 ofhello.c.```$ lldb ./hello(lldb) breakpoint set --file hello.c --line 3```This is not a problem, but if I set "--file ./hello." and then press [Tab] keyto complete file name, lldb crashes.```$ lldb ./hello(lldb) breakpoint set --file ./hello.terminate called after throwing an instance of 'std::out_of_range' what(): basic_string::substr: __pos (which is 8) > this->size() (which is 7)```The crash was caused because substr() (in lldb/source/Host/common/Editline.cpp)cut out string which size is user's input string from the completion string.I modified the code that erase the user's intput string from current line andthen add the completion string.Differential Revision: https://reviews.llvm.org/D108817 List of files: /llvm-project-15.0.7/lldb/test/API/iohandler/completion/Makefile Mon, 30 Aug 2021 12:12:29 +0000 Hiroki <h.imai.833@nitech.jp>
