Jim Blandy	89958ad0ef	Ensure that shared substrings are handled properly when passed to ... a system call or other foreign function. Many thanks to Tim Pierce! * symbols.h (SCM_COERCE_SUBSTR): new macro. * filesys.c (scm_chmod, scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink, scm_lstat), ports.c (scm_sys_make_void_port), posix.c (scm_utime, scm_putenv, scm_setlocale, scm_mknod), stime.c (setzone, scm_strftime), vports.c (scm_make_soft_port), backtrace.c (scm_display_error_message): use RO macros when strings may be RO. * error.c (scm_error_scm), filesys.c (scm_chown, scm_chmod, scm_rename, scm_delete_file, scm_mkdir, scm_rmdir, scm_opendir, scm_chdir, scm_symlink, scm_readlink, scm_lstat), ioext.c (scm_freopen, scm_duplicate_port, scm_fdopen), net_db.c (scm_gethost, scm_getnet, scm_getproto, scm_getserv), ports.c (scm_sys_make_void_port), posix.c (scm_getgrgid, scm_utime, scm_setlocale, scm_mknod), stime.c (setzone, scm_strptime, scm_strftime), vports.c (scm_make_soft_port): use SCM_COERCE_SUBSTR to make sure shared substrings are null-terminated.	1997-05-12 22:43:10 +00:00
Jim Blandy	23f53cd3e2	* backtrace.c (scm_backtrace): Split message string across ... newlines properly. GCC is more tolerant of this than other compilers.	1997-04-16 22:52:47 +00:00
Mikael Djurfeldt	78f9f47bb5	* snarf.h, backtrace.c: Name change SCM_GLOBAL --> SCM_VCELL. ... * snarf.h: Added new macros SCM_GLOBAL_SYMBOL and SCM_GLOBAL_VCELL which defines C variables with global linkage.	1997-03-21 22:53:08 +00:00
Gary Houston	c37e0e559f	* backtrace.c (scm_display_error_message): don't segv if message ... is an immediate. * error.h: prototype for scm_error_scm. * error.c (scm_error_scm): new procedure, reimplements scm-error in C and uses scm_error.	1997-03-13 00:22:20 +00:00
Mikael Djurfeldt	e3c37929e0	* * backtrace.c (scm_display_application): New procedure: ... display-application; Set fancy printing parameters individually for different types of display (backtrace, error, application). (These should of course be customizable!)	1997-03-07 21:42:32 +00:00
Mikael Djurfeldt	5aab5d961c	* symbols.c (scm_sysintern0): New function. Contains the core of ... old scm_sysintern but doesn't take a second value argument. (scm_sysintern): Now uses scm_sysintern0. (scm_sysintern_no_module_lookup): Renamed to scm_sysintern0_no_module_lookup and doesn't take a second value argument any longer. * symbols.h (scm_sysintern0: Added declaration. * options.c (scm_init_opts): Use scm_sysintern0 instead of scm_sysintern when interning option keys. Otherwise we risk destroying the values of already interned variables. * symbols.c (scm_sym2vcell): Bugfix: Treat definedp as scheme-level boolean (use SCM_NFALSEP). * backtrace.c (scm_init_backtrace): Make Scheme-level variable `the-last-stack'. (scm_backtrace): New function. (C version of old function from boot-9.scm) Motivation: Make it possible to display backtraces without depending on boot-9.scm. (I'm uncertain if this motivation is good enough...) * root.h (scm_root_state): Add member the_last_stack_var. (scm_the_stack_var): Defined to scm_root->the_last_stack_var. * root.c (mark_root): Mark scm_the_last_stack_var. * init.c (scm_start_stack): Initialize scm_the_last_stack_var to SCM_BOOL_F.	1997-02-10 01:01:54 +00:00
Marius Vollmer	016e2ce1d0	* backtrace.c (scm_display_error): Bugfix: scm_procedure_p returns ... a SCM boolean, not a C boolean.	1996-12-18 09:40:46 +00:00
Jim Blandy	f3acc5c15f	* backtrace.c (scm_display_error_message): Made non-static, and ... renamed from display_error_message. * backtrace.h (scm_display_error_message): Added extern decl. * throw.c (uncaught_throw): Use it to display the error message.	1996-12-10 01:41:37 +00:00
Mikael Djurfeldt	841076acf4	* backtrace.c (scm_display_error): Just a safety measure: Stacks ... aren't created with zero length, but should such a strange creature suddenly turn up...	1996-10-17 23:32:47 +00:00
Mikael Djurfeldt	ab4f3efbfc	* Makefile.in: Added entries for new files: backtrace.c, ... backtrace.h, stacks.c and stacks.h.	1996-10-14 03:24:16 +00:00
