* | Work around GCC bug with function attributesPaul Eggert2018-05-221-1/+1
| | | | | | | | | | | | * src/alloc.c (PNTR_ADD): Put attributes after ‘static’ and before returned type. Problem reported by Eli Zaretskii in: https://lists.gnu.org/r/emacs-devel/2018-05/msg00559.html
* | Fix failed assertion when load-force-doc-stringsPaul Eggert2018-05-221-1/+3
| | | | | | | | | | | | | | Problem reported by Philipp Stephani (Bug#31556). * src/lread.c (read_vector): When load_force_doc_strings, check for byte code vectors that are invalid because they are too short. * test/src/lread-tests.el (lread-invalid-bytecodes): New test.
* | Minor tweaks to recent fix for Bug#31545Paul Eggert2018-05-221-24/+11
| | | | | | | | | | | | | | | | * src/xwidget.c (webkit_javascript_finished_cb) (Fxwidget_webkit_execute_script): Use intptr_t to avoid warnings in the (unlikely) event that ptrdiff_t and void * differ in width. (save_script_callback): Simplify by using xlispdstrdup and larger_vector.
* | * src/xwidget.c (Fxwidget_webkit_goto_uri): Encode uri.Andreas Schwab2018-05-221-0/+1

* | Make xwidget-webkit-execute-script safe against GC (Bug#31545)Andreas Schwab2018-05-212-27/+75
| | | | | | | | | | | | | | | | | | | | | | * src/xwidget.h (struct xwidget): Add script_callbacks. * src/xwidget.c (save_script_callback): New function. (Fxwidget_webkit_execute_script): Use it. Encode script before passing to execution engine. Always use a callback. (webkit_javascript_finished_cb): Deallocate script. (kill_buffer_xwidgets): Deallocate remaining scripts. (Fxwidget_webkit_zoom): Doc fix. (Fxwidget_resize): Doc fix.

* | Port to GCC 8 -fsanitize=undefinedPaul Eggert2018-05-183-9/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In GCC 8, gcc -fsanitize=undefined flags the undefined behavior that Emacs relies on in its XPNTR and XSYMBOL low-level functions. Disable undefined sanitization in these functions. Although this disabling doesn’t suffice if DEFINE_KEY_OPS_AS_MACROS is true, it works for -fsanitize=undefined -DINLINING=0, which is good enough. * src/alloc.c (macro_PNTR_ADD): New macro. (PNTR_ADD): New function and macro. The function disables -fsanitize=undefined. (macro_XPNTR): Use it. * src/conf_post.h (ATTRIBUTE_NO_SANITIZE_UNDEFINED): New macro. * src/lisp.h (XSYMBOL): Disable -fsanitize=undefined.
* | Fix decoding of directories when "~" includes non-ASCII charsEli Zaretskii2018-05-181-15/+60
| | | | | | | | | | | | | | | | | | | | | | * src/fileio.c (Fexpand_file_name): Don't build multibyte strings from unibyte non-ASCII strings when NAME and DEFAULT_DIRECTORY have different multibyteness, as this adds bytes to the byte sequence, and in some situations, e.g., when the home directory includes non-ASCII characters, can fail file APIs. (Bug#30755) * lisp/startup.el (normal-top-level): Make sure default-directory is set to a multibyte string when decoded on MS-Windows.
