+
+2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
+
+ Fix a malloc race condition involving strsignal.
+ A signal can arrive in the middle of a malloc, and Emacs's signal
+ handler can invoke strsignal, which can invoke malloc, which is
+ not portable. This race condition bug makes Emacs hang on GNU/Linux.
+ Fix it by altering the signal handler so that it does not invoke
+ strsignal.
+ * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
+ * process.c (status_message): Use const pointer, in case strsignal
+ is #defined to safe_strsignal.
+ * sysdep.c (sys_siglist, init_signals): Always define and
+ initialize a substitute sys_siglist if the system does not define
+ one, even if HAVE_STRSIGNAL.
+ (safe_strsignal): Rename from strsignal. Always define,
+ using sys_siglist. Return a const pointer.
+ * syssignal.h (safe_strsignal): New decl.
+ (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
+
+2012-10-01 Eli Zaretskii <eliz@gnu.org>

+2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
+

+
+ * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
+ (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
+ (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
+ as the previous version used 'void *'.
+
+ * ralloc.c (ROUNDUP): Fix last change.
+ (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
+ 'size_t'.
+
+ * w32proc.c <disable_itimers>: New static flag.
+ (init_timers): Initialize it to zero, after creating the critical
+ sections used by the timer threads.
+ (term_timers): Set to 1 before deleting the critical sections.
+ (getitimer, setitimer): If disable_itimers is non-zero, return an

+ <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
+
+ Prefer plain 'static' to 'static inline' (Bug#12541).
+ With static functions, modern compilers inline pretty well by
+ themselves; advice from programmers often hurts as much as it helps.
+ On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
+ this change shrinks the text size of the Emacs executable by 1.1%
+ without affecting CPU significantly in my benchmark.

+
+ Simplify and avoid signal-handling races (Bug#12471).
+ * alloc.c (die):
+ * sysdep.c (emacs_abort) [HAVE_NTGUI]:
+ Avoid recursive loop if there's a fatal error in the function itself.
+ * atimer.c (pending_atimers):
+ * blockinput.h: Don't include "atimer.h"; no longer needed.
+ (interrupt_input_pending): Remove. All uses removed.
+ pending_signals now counts both atimers and ordinary interrupts.
+ This is less racy than having three separate pending-signal flags.
+ (block_input, unblock_input, totally_unblock_input, unblock_input_to)
+ (input_blocked_p):
+ Rename from their upper-case counterparts BLOCK_INPUT,
+ UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
+ INPUT_BLOCKED_P, and turn into functions. All uses changed.
+ This makes it easier to access volatile variables more accurately.
+ (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
+ (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
+ that's more reliable if the code is buggy and sets
+ interrupt_input_blocked to a negative value. All uses changed.
+ * atimer.c (deliver_alarm_signal):
+ Remove. No need to deliver this to the parent; any thread can
+ handle this signal now. All uses replaced by underlying handler.
+ * atimer.c (turn_on_atimers):
+ * dispnew.c (handle_window_change_signal):
+ * emacs.c (handle_danger_signal):

+ * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
+ (fatal_error_code): Remove; no longer needed.
+ (terminate_due_to_signal): Rename from fatal_error_backtrace, since
+ it doesn't always backtrace. All uses changed. No need to reset
+ signal to default, since sigaction and/or die does that for us now.
+ Use emacs_raise (FOO), not kill (getpid (), FOO).
+ (main): Check more-accurately whether we're dumping.
+ Move fatal-error setup to sysdep.c
+ * floatfns.c: Do not include "syssignal.h"; no longer needed.
+ * gtkutil.c (xg_get_file_name, xg_get_font):

+ * keyboard.c, process.c (POLL_FOR_INPUT):
+ Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
+ * keyboard.c (read_avail_input): Remove.
+ All uses replaced by gobble_input.
+ (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
+ (kbd_buffer_store_event_hold, gobble_input):
+ (record_asynch_buffer_change) [USABLE_SIGIO]:
+ (store_user_signal_events):
+ No need to mess with signal mask.
+ (gobble_input): If blocking input and there are terminals, simply
+ set pending_signals to 1 and return. All hooks changed to not
+ worry about whether input is blocked.
+ (process_pending_signals): Clear pending_signals before processing
+ them, in case a signal comes in while we're processing.
+ By convention callers now test pending_signals before calling us.
+ (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
+ New functions, to support changes to blockinput.h.
+ (handle_input_available_signal): Now extern.
+ (reinvoke_input_signal): Remove. All uses replaced by
+ handle_async_input.
+ (quit_count): Now volatile, since a signal handler uses it.
+ (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
+ All callers changed. Block SIGINT only if not already blocked.
+ Clear sigmask reliably, even if Fsignal returns, which it can.
+ Omit unnecessary accesses to volatile var.
+ (quit_throw_to_read_char): No need to restore sigmask.
+ * keyboard.c (gobble_input, handle_user_signal):
+ * process.c (wait_reading_process_output):

+ (syms_of_data): Now const if IEEE floating point.
+ (handle_input_available_signal) [USABLE_SIGIO]:
+ (terminate_due_to_signal, record_child_status_change): New decls.
+ * process.c (create_process): Avoid disaster if memory is exhausted
+ while we're processing a vfork, by tightening the critical section
+ around the vfork.
+ (send_process_frame, process_sent_to, handle_pipe_signal)
+ (deliver_pipe_signal): Remove. No longer needed, as Emacs now
+ ignores SIGPIPE.
+ (send_process): No need for setjmp/longjmp any more, since the
+ SIGPIPE stuff is now gone. Instead, report an error if errno
+ is EPIPE.
+ (record_child_status_change): Now extern. PID and W are now args.
+ Return void, not bool. All callers changed.
+ * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
+ Remove. All uses removed. This bug should be fixed now in a
+ different way.
+ (wait_for_termination_1): Use waitpid rather than sigsuspend,
+ and record the child status change directly. This avoids the
+ need to futz with the signal mask.
+ (process_fatal_action): Move here from emacs.c.
+ (emacs_sigaction_flags): New function, containing
+ much of what used to be in emacs_sigaction_init.
+ (emacs_sigaction_init): Use it. Block nonfatal system signals that are
+ caught by emacs, to make races less likely.
+ (deliver_process_signal): Rename from handle_on_main_thread.
+ All uses changed.
+ (BACKTRACE_LIMIT_MAX): Now at top level.
+ (thread_backtrace_buffer, threadback_backtrace_pointers):
+ New static vars.
+ (deliver_thread_signal, deliver_fatal_thread_signal):
+ New functions, for more-accurate delivery of thread-specific signals.
+ (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
+ (deliver_arith_signal): Handle in this thread, not
+ in the main thread, since it's triggered by this thread.
+ (maybe_fatal_sig): New function.
+ (init_signals): New arg DUMPING so that we can be more accurate
+ about whether we're dumping. Caller changed.
+ Treat thread-specific signals differently from process-general signals.
+ Block all signals while handling fatal error; that's safer.
+ xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
+ on IEEE hosts.
+ When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
+ Ignore SIGPIPE unless batch.
+ (emacs_backtrace): Output backtrace for the appropriate thread,
+ which is not necessarily the main thread.
+ * syssignal.h: Include <stdbool.h>.
+ (emacs_raise): New macro.
+ * xterm.c (x_connection_signal): Remove; no longer needed
+ now that we use sigaction.
+ (x_connection_closed): No need to mess with sigmask now.
+ (x_initialize): No need to reset SIGPIPE handler here, since
+ init_signals does this for us now.

+ Assume C89 or later for math functions (Bug#12381).
+ This simplifies the code, and makes it a bit smaller and faster,

+ * floatfns.c: Comment fix.

+ Include <sys/ioctl.h>, for FIONREAD.
+ * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.

+
+ Signal-handler cleanup (Bug#12327).
+ Emacs's signal handlers were written in the old 4.2BSD style with
+ sigblock and sigmask and so forth, and this led to some
+ inefficiencies and confusion. Rewrite these to use
+ pthread_sigmask etc. without copying signal sets around. Also,
+ get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
+ 'signal', and instead use functions that do not attempt to take
+ over the system name space. This patch causes Emacs's text
+ segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
+ * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
+ Do not include <signal.h> or "syssignal.h", as these
+ modules do not use signals.
+ * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
+ * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
+ Do not include <signal.h>, as "syssignal.h" does that for us now.
+ * atimer.c (sigmask_atimers): New function.
+ (block_atimers, unblock_atimers): New functions,
+ replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
+ All uses replaced.
+ * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
+ no longer needed here.
+ * emacs.c (main): Inspect existing signal handler with sigaction,
+ so that there's no need to block and unblock SIGHUP.
+ * sysdep.c (struct save_signal): New member 'action', replacing
+ old member 'handler'.
+ (save_signal_handlers, restore_signal_handlers):
+ Use sigaction instead of 'signal' to save and restore.
+ (get_set_sighandler, set_sighandler) [!WINDOWSNT]:

+ if they're writeonly, and to use sys_signal if they're read+write.
+ (emacs_sigaction_init, forwarded_signal): New functions.

+ (sigsetmask) [!defined sigsetmask]:
+ Remove. All uses replaced by pthread_sigmask.
+ (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
+ no longer need to be replaced, and its typical old uses
+ are now done via emacs_sigaction_init and sigaction.
+ (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
+ (sys_sigdel): Remove; unused.
+ (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
