+
+ Count overruns when profiling; change units to ns.
+ * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
+ Give extra weight to samples after overruns, to attempt to count
+ the time more accurately.
+ (setup_cpu_timer): Change sampling interval units from ms to ns, since
+ the underlying primitives nominally do ns.
+ (Fprofiler_cpu_start): Document the change. Mention that
+ the sampling intervals are only approximate.

+
+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.

+
+ * 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

+ (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
+ return results.
+ [!HAVE_SETITIMER]: Behave as the previous version that didn't
+ support timers.
+
+ * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
+ term_ntproc after all the other bookkeeping, to get timers working
+ as long as possible.

+ * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
+ Suggested by Juri Linkov in
+ <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.
