2022-09-28Port better to C23 bool+true+false keywordsPaul Eggert
C23 is adding the C++ keywords bool, true, and false; prefer them to <stdbool.h> if they are available. * admin/merge-gnulib (GNULIB_MODULES): Add stdbool, which emulates C23 on pre-C23 platforms. (AVOIDED_MODULES): Remove stdbool; Gnulib has renamed this module to stdbool-c99 and nobody uses it so it does not need to be avoided. * m4/c-bool.m4: New file, from Gnulib stdbool module. * lib-src/seccomp-filter.c, src/conf_post.h, src/dynlib.h: * src/emacs-module.c, src/nsterm.m, src/systhread.h: * test/src/emacs-module-resources/mod-test.c: Use the C23 style and use bool without including <stdbool.h>. The Gnulib stdbool module causes config.h to include stdbool.h on pre-C23 platforms. * src/emacs-module.h.in: Don’t include <stdbool.h> if C23 or later, or if it has already been included.
2022-03-08Do not include <attribute.h> from <config.h>Paul Eggert
This is because mod-test.c shouldn’t use source code from lib, but it does need to include <config.h>. * lib-src/ebrowse.c, lib-src/emacsclient.c, lib-src/etags.c: * lib-src/make-docfile.c, lib-src/movemail.c: * lib-src/seccomp-filter.c, src/dynlib.h, src/lisp.h: * src/syssignal.h, src/sysstdio.h, src/systhread.h, src/tparam.h: Include <attribute.h>. * src/conf_post.h: Do not include <attribute.h>. All uses of attribute.h macros replaced with their _GL_ equivalents.

2019-05-05Avoid suppressing -Wcast-function-type warning.Philipp Stephani
GCC special-cases the type ‘void (*)(void)’ to not emit warnings when cast, see https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wcast-function-type. Make use of this to remove a warning suppression. * src/dynlib.h: Use void (*)(void) as generic function pointer type. * src/emacs-module.c: Remove warning suppression.
2019-04-25Port to Oracle Developer Studio 12.6Paul Eggert
This compiler is a bit pickier about checking conformance to the C standard, ranging from syntax trivia (no extra ";" at the top level) to portability trivia (warnings re conversion between function and data pointers) to more-important stuff like lack of support for some __attribute__ usages. * src/dynlib.c (dynlib_addr): First argument is a function pointer, not a data pointer. 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.

2017-09-13Prefer HTTPS to FTP and HTTP in documentationPaul Eggert
Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.
2017-06-04Use ATTRIBUTE_MAY_ALIAS where alias violations are likelyPhilipp Stephani
In particular, alias violations are likely for the return values of dlsym(3), which get cast around arbitrarily. * src/emacs-module.c (Fmodule_load): Use ATTRIBUTE_MAY_ALIAS.
2017-06-04Simplify interface of dynlib_attr.Philipp Stephani
Instead of returning bool, set the argument pointers to NULL if the information is not available. * src/dynlib.c (dynlib_addr): Don't return bool.

2016-03-10Rework C source files to avoid ^(Paul Eggert
Work around Bug#22884 by rewording comments and strings to avoid ‘(’ at the start of a line unless it starts a function. This change is a short-term hack; in the longer run we plan to fix cc-mode’s performance for C files that have ‘(’ at the start of a line in a comment or string.

2015-11-23Port better to FreeBSD’s dlfunc vs dlsymPaul Eggert
This avoids warnings when converting between void * and function pointers, which strict C11 does not allow. * configure.ac (dlfunc): Check for existence. * src/dynlib.c (dlfunc) [!HAVE_DLFUNC]: New macro. (dynlib_func): New function. * src/dynlib.h (dynlib_function_ptr, dynlib_func): New decls. * src/emacs-module.c (Fmodule_load): Use dynlib_func, not dynlib_sym, for function pointers.
2015-11-20Include-file tweaks for modulesPaul Eggert
* src/dynlib.c, src/emacs-module.c: Include <config.h> first. * src/dynlib.h: Do not include config.h. It’s every .c file’s responsibility to include config.h first. * src/emacs-module.c: Include emacs-module.h immediately after config.h, to test that emacs-module.h doesn’t depend on include files other than config.h.
2015-11-19Style fixes for indenting etc. in module codePaul Eggert
This is mostly indenting and spacing changes. Also, remove some unnecessary static decls instead of bothering to reindent them. * src/module.h (EMACS_EXTERN_C_BEGIN): Remove, and do this inline, as most other Emacs files do for this sort of thing.
2015-11-19Add copyright notices to module codePaul Eggert
Put them in the usual format for GNU Emacs copyright notices.
