* | Avoid assertion violations in calculating line-number widthEli Zaretskii2019-04-261-2/+5
| | | | | | | | | | | | * src/indent.c (line_number_display_width): Don't use the window's start marker if it belongs to a different buffer. (Bug#35429)
* | Avoid compiler warning in dynlib.cEli Zaretskii2019-04-261-1/+2
| | | | | | | | | | | | | | | | * src/dynlib.c (dynlib_addr) [WINDOWSNT]: Rename the first argument to be consistent with other platforms. Cast it to 'void *' to avoid compiler warning as result of changing the function's signature as part of the last recent change in dynlib.c.
* | Minor tweaks to recent UBSan-related fixPaul Eggert2019-04-251-14/+6
| | | | | | | | | | | | | | | | | | | | * src/alloc.c: No need to include stdalign.h; it’s pervasive. (GC_STRING_OVERRUN_COOKIE_SIZE): Align to sdata’s alignment, so that the code works even if alignof (sdata) exceeds 8. Don’t require the cookie size to be 8, as this overly fattens 32-bit platforms and one DEADBEEF should be enough. (GC_STRING_EXTRA): Omit now-unnecessary ‘verify’. (allocate_string_data): Omit unnecessary cast.
* | Port to Oracle Developer Studio 12.6Paul Eggert2019-04-258-48/+61

All callers changed. * src/emacs-module.c (module_function_address): Return module_funcptr, not void *. All uses changed. * src/lisp.h (module_funcptr) [HAVE_MODULES]: New type. * src/lread.c (union ieee754_double): Don’t assume the usual semantics for converting signed to unsigned int when initializing a bitfield, as the Oracle compiler complains and the C standard is unclear. * src/pdumper.c (ALLOW_IMPLICIT_CONVERSION): Make it clearer that -Wsign-conversion is disabled everywhere in this file. (dump_trace, dump_tailq_prepend, dump_tailq_append): Don’t assume __attribute__. (dump_object_self_representing_p): Don’t disable conversion warnings; it’s not needed here. (DEFINE_FROMLISP_FUNC): Avoid possible signal in integer conversion from unsigned to signed. (DEFINE_FROMLISP_FUNC, finish_dump_pvec): Avoid warning about unreachable statements on platforms not supporting the __attribute__. (intmax_t_from_lisp, intmax_t_to_lisp, dump_off_from_lisp) (dump_off_to_lisp, dump_emacs_reloc_immediate_lv) (dump_emacs_reloc_immediate_ptrdiff_t) (dump_emacs_reloc_immediate_intmax_t) (dump_emacs_reloc_immediate_int, dump_emacs_reloc_immediate_bool): Omit stray semicolon that violates C standard. (dump_metadata_for_pdumper): Add cast to pacify compiler complaining about conversion from function pointer to data pointer. (Fdump_emacs_portable): Do not use CALLN to call a function with zero arguments, as C99 prohibits empty initializers. * src/xdisp.c (syms_of_xdisp): Do not nest calls to pure_list, to work around a bug in Oracle Developer Studio 12.6.
* | Make sure that ‘sdata’ objects in ‘sblock’ objects are aligned.Philipp Stephani2019-04-251-2/+10
| | | | | | | | | | | | | | | | | | Issue found by Clang’s UBSan. * src/alloc.c (GC_STRING_OVERRUN_COOKIE_SIZE): Increase to 8. (string_overrun_cookie): Extend accordingly. (GC_STRING_EXTRA): Ensure that it’s properly aligned for ‘sdata’. (allocate_string_data): Verify that ‘sdata’ blocks remain aligned.
* | Unbreak build when building without GMP support.Philipp Stephani2019-04-242-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for a new preprocessor macro EMACS_MODULE_HAVE_MPZ_T to emacs-module.h. If this macro is defined, assume that mpz_t is already defined and don’t include gmp.h. Don’t document the new macro for now, as it’s unclear whether we want to support this in modules outside the Emacs tree. * src/emacs-module.h.in: Allow user to prevent inclusion of gmp.h. * src/emacs-module.c: Use mini-gmp if GMP is unavailable. Don’t include gmp.h. * src/lisp.h: Don’t require gmp.h. It’s not needed for lisp.h. * test/Makefile.in (GMP_LIB, GMP_OBJ): New variables. ($(test_module)): Use them. * test/data/emacs-module/mod-test.c: Use mini-gmp if GMP is unavailable.
* | Move definition of Lisp_Module_Function to emacs-module.c.Philipp Stephani2019-04-244-29/+45

Remove definition of Lisp_Module_Function structure. * src/emacs-module.c (module_function_documentation) (module_function_address): New accessor functions for module function fields. (emacs_subr, struct Lisp_Module_Function): Move from lisp.h. * src/print.c (print_vectorlike): * src/doc.c (Fdocumentation): Use the new accessor functions.
* | Simplify thread initialization and GCPaul Eggert2019-04-245-74/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | * src/lisp.h (PVECHEADERSIZE): New macro. (XSETPVECTYPESIZE): Use it. * src/search.c (syms_of_search): No need to initialize or staticpro last_thing_searched or saved_last_thing_searched, as the thread code arranges for initialization and GC. * src/thread.c (main_thread): Initialize statically. (Fmake_mutex, Fmake_condition_variable, Fmake_thread): Use ALLOCATE_ZEROED_PSEUDOVECTOR rather than zeroing by hand. (mark_one_thread): No need to mark Lisp_Object members. (init_main_thread, init_threads_once): Remove. All uses removed.
* | Fix posn-at-point with line-number display and display propertiesEli Zaretskii2019-04-241-0/+6
| | | | | | | | | | | | * src/xdisp.c (pos_visible_p): Account for line-number display width when CHARPOS is covered by display property that begins at the 2nd display element of a screen line. (Bug#35404)
* | Fix a typo in a recent commitEli Zaretskii2019-04-241-1/+1
| | | | | | | | | | * src/timefns.c (timespec_to_lisp): Fix a typo in function definition.
* | Fix return type of make_time.Philipp Stephani2019-04-243-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | make_time is documented to return a (TICKS . HZ) pair, so we can’t use make_lisp_time. Introduce a new conversion function instead. * src/emacs-module.c (module_make_time): Use timespec_to_lisp to correct return type. * src/timefns.c (timespec_to_lisp): New function. (make_lisp_time): Use it. * test/src/emacs-module-tests.el (mod-test-add-nanosecond/valid): Check return type.
* | Add module functions to convert from and to big integers.Philipp Stephani2019-04-244-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * src/module-env-27.h: Add new module functions to convert big integers. * src/emacs-module.h.in (emacs_mpz): Define if GMP is available. * src/emacs-module.c (module_extract_big_integer) (module_make_big_integer): New functions. (initialize_environment): Use them. * test/data/emacs-module/mod-test.c (Fmod_test_double): New test function. (emacs_module_init): Define it. * test/src/emacs-module-tests.el (mod-test-double): New unit test. * doc/lispref/internals.texi (Module Values): Document new functions.
* | Add conversions to and from struct timespec to module interface.Philipp Stephani2019-04-243-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Time values are a fundamental data type, and such conversions are hard to implement within modules because of the various forms of time values in Emacs Lisp. Adding dedicated conversion functions can significantly simplify module code dealing with times. This approach uses nanosecond precision. While Emacs in theory has support for higher-precision time values, in practice most languages and standards, such as POSIX, C, Java, and Go, have settled on nanosecond-precision integers to represent time. * src/emacs-module.h.in: Add header for struct timespec. * src/module-env-27.h: Add module functions for time conversion. * src/emacs-module.c (module_extract_time, module_make_time): New functions. (initialize_environment): Use them. * test/data/emacs-module/mod-test.c (Fmod_test_add_nanosecond): New test function. (emacs_module_init): Define it. * test/src/emacs-module-tests.el (mod-test-add-nanosecond/valid) (mod-test-add-nanosecond/nil, mod-test-add-nanosecond/invalid): New unit tests. * doc/lispref/internals.texi (Module Values): Document time conversion functions.
* | Revert "Remove font.c code commented out for a decade"Eli Zaretskii2019-04-241-0/+465
| | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 64d0cd9810af6bd0c378fc6bc666c76ddfa97e40. Rationale: any font-related code and comments, even if unused for decades, serves as important source of useful information in an area of Emacs code that is notoriously under-documented. Please do NOT remove this stuff until we have an active expert in this are on board, who will then decide whether this can be retired.
