| | | | | | | | * src/font.c (font_score, font_delete_unmatched): Don't assume weight, slant, and width properties of the font must be fixnums: some variable-weight fonts violate that assumption. Reported by Sean Whitton <spwhitton@spwhitton.name>. Do not merge to master. (Bug#52888)

| | | | | | | | This is the same as 44c13eefe8d30841000a96d82f467fb8d222e365 on master. We should also remove this comment on the release branch, otherwise it ends up in the emacs-module.h shipped to users. * src/module-env-28.h: Remove maintainer comment.

| | | | * src/pdumper.c (dump_subr): Fix Lisp_Subr hash value.
* Port to C compilers that lack size-0 arraysPaul Eggert2021-12-028-71/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The C standard does not allow size-zero arrays, so redo struct Lisp_Subr to not use size-zero arrays when native compilation is not being used. Formerly, the code was using size-zero arrays (a GNU C extension) to avoid using memory unnecessarily when HAVE_NATIVE_COMP is not defined. Replace this hack with the more-traditional hack of putting the relevant members inside ‘#ifdef HAVE_NATIVE_COMP’. * src/alloc.c (cleanup_vector, mark_object): * src/comp.c (make_subr): * src/data.c (Fsubr_native_lambda_list, Fsubr_native_comp_unit): * src/eval.c (init_eval_once, funcall_lambda): * src/lisp.h (SUBR_NATIVE_COMPILEDP, SUBR_NATIVE_COMPILED_DYNP) (SUBR_TYPE): * src/lread.c (Fload): Conditionally compile with ‘#ifdef HAVE_NATIVE_COMP’ instead of with ‘if (NATIVE_COMP_FLAG)’. Redo members like native_comp_u[0] to be plain native_comp_u. Put all uses of these members inside ‘#ifdef HAVE_NATIVE_COMP’. * src/lisp.h (struct Lisp_Subr): Members native_comp_u, native_c_name, lambda_list, type are now all ifdeffed out if HAVE_NATIVE_COMP is not defined, instead of being size-zero arrays. All uses changed. * src/pdumper.c (dump_subr, dump_cold_native_subr) (dump_do_dump_relocation): * src/comp.h (NATIVE_COMP_FLAG): Remove; no longer needed.
* Work around IBM XL C compiler bugPaul Eggert2021-12-021-1/+3
| | | | | | | | * src/fileio.c (Fcopy_file): Work around a compiler bug in IBM XL C for AIX, V12.1 (5765-J02, 5725-C72). Without this patch, the compiler incorrectly complains “Initialization between types "int" and "struct timespec" is not allowed” and “Initialization between types "long" and "struct timespec" is not allowed”.

* Use posix_spawn if possible.Philipp Stephani2021-11-131-1/+189
| | | | | | | | | | | | | | | | | | | | | | | | | posix_spawn is less error-prone than vfork + execve, and can make better use of system-specific enhancements like 'clone' on Linux. Use it if we don't need to configure a pseudoterminal. Backported from commit a60053f8368e058229721f1bf1567c2b1676b239. Unlike that commit, only define USABLE_POSIX_SPAWN on macOS, because there posix_spawn is much faster than vfork. Don't merge to master. * configure.ac (HAVE_SPAWN_H, HAVE_POSIX_SPAWN) (HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR) (HAVE_POSIX_SPAWN_FILE_ACTIONS_ADDCHDIR_NP) (HAVE_POSIX_SPAWNATTR_SETFLAGS, HAVE_DECL_POSIX_SPAWN_SETSID): New configuration variables. * src/callproc.c (USABLE_POSIX_SPAWN): New configuration macro. (emacs_posix_spawn_init_actions) (emacs_posix_spawn_init_attributes, emacs_posix_spawn_init): New helper functions. (emacs_spawn): Use posix_spawn if possible.
