* Initial commit. Allow wanted fontification of open string in any mode.scratch/fontify-open-stringAlan Mackenzie2018-07-011-9/+184
| | | | | | | | | | | | | | | | | The wanted fontification is for the string face to end at the first unescaped newline. This is achieved by a new syntax flag `s' on NL, which means "terminate any open string". src/syntax.c (SYNTAX_FLAGS_CLOSE_STRING, back_maybe_string): New functions. (Fstring_to_syntax, Finternal_describe_syntax_value, scan_lists) (scan_sexps_forward): Adapt to handle the `s' flag. lisp/font-lock.el (font-lock-warn-open-string): New defcustom. (font-lock-fontify-syntactically-region): Enhance to fontify " with warning-face. lisp/progmodes/sh-script.el (sh-mode-syntax-table): Add flag `s' to syntax entry for \n.
* Tune SAFE_FREEPaul Eggert2018-06-2813-44/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | On my platform (Fedora 28 x86-64, AMD Phenom II X4 910e) this sped up a SAFE_FREE-using microbenchmark (string-distance "abc" "abc") by about 18%, and shrank the Emacs text size by about 0.1%. * src/callint.c (Fcall_interactively): * src/callproc.c (call_process): * src/doc.c (get_doc_string, Fsnarf_documentation): * src/editfns.c (Freplace_buffer_contents): * src/emacs-module.c (funcall_module): * src/eval.c (Flet): * src/process.c (Fmake_process): * src/term.c (tty_menu_show): * src/xdisp.c (safe__call): * src/xmenu.c (x_menu_show): Use SAFE_FREE_UNBIND_TO. * src/data.c (wrong_choice): No need to call SAFE_FREE here. * src/lisp.h (USE_SAFE_ALLOCA): * src/regex.c (REGEX_USE_SAFE_ALLOCA): Do not declare sa_must_free local; no longer needed.

* (format "%d" F) now truncates floating FPaul Eggert2018-06-253-9/+16
| | | | | | | | | | | | | Problem reported by Paul Pogonyshev (Bug#31938). * src/editfns.c: Include math.h, for trunc. (styled_format): For %d, truncate floating-point numbers and convert -0 to 0, going back to how Emacs 26 did things. * doc/lispref/strings.texi (Formatting Strings): Document behavior of %o, %d, %x, %X on floating-point numbers. * src/floatfns.c (trunc) [!HAVE_TRUNC]: Rename from emacs_trunc and make it an extern function, so that editfns.c can use it. All callers changed. * test/src/editfns-tests.el (format-%d-float): New test.
* Clean up redundant code from previous checkinsLars Ingebrigtsen2018-06-251-1/+0
| | | | | | * src/gnutls.c (gnutls_verify_boot): Remove reduntant setting of p->gnutls_certificates, which is now performed by gnutls_deinit_certificates.

| | | | | | | | | | | | * src/gnutls.c (gnutls_deinit_certificates): New function. (Fgnutls_peer_status): Return all certificates in the chain back to Lisp land. (gnutls_verify_boot): Compute all the x509 certificates in the chain. * src/process.h (struct Lisp_Process): Adjust gnutls fields so that we can keep tracks of all certificates in the chain instead of just the host certificate.

All uses changed. * src/eval.c (default_toplevel_binding, Fbacktrace__locals): Treat excursions like other miscellaneous pdl types. (record_unwind_protect_excursion): Save data directly into the pdl rather than creating an object on the heap. This avoids the need to allocate and free an object.
