Generalize varobj iterator This patch generalizes varobj iterator, in a python-independent way. Note varobj_item is still a typedef of PyObject, we can only focus on API changes, and leave the data type changes to the next patch. As a result, we include "varobj-iter.h" after the typedef of PyObject in varobj.c, but it is an intermediate state. Finally, varobj-iter.h is independent of PyObject. This change is helpful to move some python-related code out of varobj.c. V2: - Fix a missing cleanup. - Fix typos. - Use XNEW. - Check against NULL explicitly. - Update copyright year for new added files. V3: - Call PyGILState_Ensure before Py_XDECREF. - Use CPYCHECKER_STEALS_REFERENCE_TO_ARG. - Code indentation.

Normalize include guards in gdb While working on my other scripts to deal with gdb headers, I noticed that some files were missing include guards. I wrote a script to add the missing ones, but found that using the obvious names for the guards ran into clashes -- for example, gdb/nat/linux-nat.h used "LINUX_NAT_H", but this was also the script's choice for gdb/linux-nat.h. So, I changed the script to normalize all include guards in gdb. This patch is the result. As usual the script is available here: https://github.com/tromey/gdb-refactoring-scripts Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the buildbot. gdb/ChangeLog 2019-02-07 Tom

Use ui_file_as_string throughout more This replaces most of the remaining ui_file_xstrdup calls with ui_file_as_string calls. Whenever a call was replaced, that led to a cascade of other necessary adjustments throughout, to make the code use std::string instead of raw pointers. And then whenever I added a std::string as member of a struct, I needed to adjust allocation/destruction of said struct to use new/delete instead of xmalloc/xfree. The stopping point was once gdb built again. These doesn't seem to be a way to reasonably split this out further. Maybe-not-obvious changes: - demangle_for_lookup returns a cleanup today. To get rid of that, and avoid unnecessary string dupping/copying, this introduces a demangle_result_storage type that the caller instantiates and passes to demangle_for_lookup. - Many methods returned a "char *" to indicate that the caller owns the memory and must free it. Those are switched to return a std::string instead. Methods that return a "view" into some internal string return a "const char *" instead. I.e., we only copy/allocate when necessary. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_name_for_lookup, type_as_string): Use and return std::string.

Generalize varobj iterator This patch generalizes varobj iterator, in a python-independent way. Note varobj_item is still a typedef of PyObject, we can only focus on API changes, and leave the data type changes to the next patch. As a result, we include "varobj-iter.h" after the typedef of PyObject in varobj.c, but it is an intermediate state. Finally, varobj-iter.h is independent of PyObject. This change is helpful to move some python-related code out of varobj.c. V2: - Fix a missing cleanup. - Fix typos. - Use XNEW. - Check against NULL explicitly. - Update copyright year for new added files. V3: - Call PyGILState_Ensure before Py_XDECREF. - Use CPYCHECKER_STEALS_REFERENCE_TO_ARG. - Code indentation. V4: - use varobj_ensure_python_env instead of PyGILState_Ensure. gdb: 2014-06-12 Pedro Alves <pedro@codesourcery.com> Yao Qi <yao@codesourcery.com> * Makefile.in (SUBDIR_PYTHON_OBS): Add "py-varobj.o".

Normalize include guards in gdb While working on my other scripts to deal with gdb headers, I noticed that some files were missing include guards. I wrote a script to add the missing ones, but found that using the obvious names for the guards ran into clashes -- for example, gdb/nat/linux-nat.h used "LINUX_NAT_H", but this was also the script's choice for gdb/linux-nat.h. So, I changed the script to normalize all include guards in gdb. This patch is the result. As usual the script is available here: https://github.com/tromey/gdb-refactoring-scripts Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the buildbot. gdb/ChangeLog 2019-02-07 Tom
