From b3f8bee89e3fa5713ff391e0172b8e1d4b92be25 Mon Sep 17 00:00:00 2001 From: Kaz Kylheku Date: Thu, 12 Dec 2013 22:47:27 -0800 Subject: First cut at signal handling support. * Makefile (OBJS-y): Include signal.o if have_posix_sigs is "y". * configure (have_posix_sigs): New variable, set by detecting POSIX signal stuff. * dep.mk: Regenerated. * arith.c, debug.c, eval.c, filter.c, hash.c, match.c, parser.y, parser.l, rand.c, regex.c, syslog.c, txr.c, utf8.c: Include new signal.h header, now required by unwind, and the system header. * eval.c (exit_wrap): New function. (eval_init): New functions registered as intrinsics: exit_wrap, set_sig_handler, get_sig_handler, sig_check. * gc.c (release): Unused functions removed. * gc.h (release): Declaration removed. * lib.c (init): Call sig_init. * stream.c (set_putc, se_getc, se_fflush): New static functions. (stdio_put_char_callback, stdio_get_char_callback, stdio_put_byte, stdio_flush, stdio_get_byte): Use new functions to enable signals when blocked on I/O. (tail_strategy): Allow signals across sleep. (pipev_close): Allow signals across waitpid. (se_pclose): New static function. (pipe_close): Use new function to enable signals across pclose. * unwind.c (uw_unwind_to_exit_point): use extended_longjmp instead of longjmp. * unwind.h (struct uw_block, struct uw_catch): jb member changes from jmp_buf to extended_jmp_buf. (uw_block_begin, uw_simple_catch_begin, uw_catch_begin): Use extended_setjmp instead of setjmp. * signal.c: New file. * signal.h: New file. --- regex.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'regex.c') diff --git a/regex.c b/regex.c index 85a91ed1..dfe872a8 100644 --- a/regex.c +++ b/regex.c @@ -33,9 +33,11 @@ #include #include #include +#include #include "config.h" #include "lib.h" #include "parser.h" +#include "signal.h" #include "unwind.h" #include "regex.h" #include "txr.h" -- cgit v1.2.3
