+
+ Import getloadavg module from gnulib.
+ * .bzrignore: Add lib/stdlib.h.
+ * Makefile.in (GNULIB_MODULES): Add getloadavg.
+ * admin/notes/copyright: Remove src/getloadavg.c as a special case.
+ * configure.in (LIBS_SYSTEM): Omit -lkstat on sol2*; gnulib does this.
+ (AC_CONFIG_LIBOBJ_DIR, AC_FUNC_GETLOADAVG, GETLOADAVG_FILES):
+ Remove; gnulib does this now.
+ * lib/getloadavg.c: Rename from src/getloadavg.c, and sync
+ from gnulib. This adds support for several other systems, such
+ as Tru64 4.0D, QNX, AIX perfstat, etc. It also fixes a potential
+ buffer overrun on Linux hosts under very high load, and on hosts
+ that maintain a channel to the load average file it makes sure
+ the file descriptor is close-on-exec (on hosts that support this)
+ and is not stdin, stdout, or stderr.
+ * lib/stdlib.in.h, m4/getloadavg.m4, m4/stdlib_h.m4: New files,
+ from gnulib.
+ * aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk, m4/gl-comp.m4:
+ * src/config.in: Regenerate.

+/* Compile-time symbols that this file uses:
+
+ HAVE_PSTAT_GETDYNAMIC Define this if your system has the
+ pstat_getdynamic function. I think it
+ is unique to HPUX9. The best way to get the
+ definition is through the AC_FUNC_GETLOADAVG
+ macro that comes with autoconf 2.13 or newer.
+ If that isn't an option, then just put
+ AC_CHECK_FUNCS(pstat_getdynamic) in your
+ configure.in file.
+ HAVE_LIBPERFSTAT Define this if your system has the
+ perfstat_cpu_total function in libperfstat (AIX).
+ FIXUP_KERNEL_SYMBOL_ADDR() Adjust address in returned struct nlist.
+ KERNEL_FILE Name of the kernel file to nlist.
+ LDAV_CVT() Scale the load average from the kernel.
+ Returns a double.
+ LDAV_SYMBOL Name of kernel symbol giving load average.
+ LOAD_AVE_TYPE Type of the load average array in the kernel.
+ Must be defined unless one of
+ apollo, DGUX, NeXT, or UMAX is defined;
+ or we have libkstat;
+ otherwise, no load average is available.
+ HAVE_NLIST_H nlist.h is available. NLIST_STRUCT defaults
+ to this.
+ NLIST_STRUCT Include nlist.h, not a.out.h.
+ N_NAME_POINTER The nlist n_name element is a pointer,
+ not an array.
+ HAVE_STRUCT_NLIST_N_UN_N_NAME `n_un.n_name' is member of `struct nlist'.
+ LINUX_LDAV_FILE [__linux__, __CYGWIN__]: File containing
+ load averages.
+
+ Specific system predefines this file uses, aside from setting
+ default values if not emacs:
+
+ apollo
+ BSD Real BSD, not just BSD-like.
+ convex
+ DGUX
+ eunice UNIX emulator under VMS.
+ hpux
+ __MSDOS__ No-op for MSDOS.
+ NeXT

+ sequent Sequent Dynix 3.x.x (BSD)
+ _SEQUENT_ Sequent DYNIX/ptx 1.x.x (SYSV)
+ sony_news NEWS-OS (works at least for 4.1C)
+ UMAX
+ UMAX4_3
+ VMS
+ WINDOWS32 No-op for Windows95/NT.
+ __linux__ Linux: assumes /proc file system mounted.
+ Support from Michael K. Johnson.
+ __CYGWIN__ Cygwin emulates linux /proc/loadavg.
+ __NetBSD__ NetBSD: assumes /kern file system mounted.
+
+ In addition, to avoid nesting many #ifdefs, we internally set
+ LDAV_DONE to indicate that the load average has been computed.
+
+ We also #define LDAV_PRIVILEGED if a program will require
+ special installation to be able to call getloadavg. */

- HAVE_PSTAT_GETDYNAMIC Define this if your system has the
- pstat_getdynamic function. I think it
- is unique to HPUX9. The best way to get the
- definition is through the AC_FUNC_GETLOADAVG
- macro that comes with autoconf 2.13 or newer.
- If that isn't an option, then just put
- AC_CHECK_FUNCS(pstat_getdynamic) in your
- configure.in file.
- FIXUP_KERNEL_SYMBOL_ADDR() Adjust address in returned struct nlist.
- KERNEL_FILE Pathname of the kernel to nlist.
- LDAV_CVT() Scale the load average from the kernel.
- Returns a double.
- LDAV_SYMBOL Name of kernel symbol giving load average.
- LOAD_AVE_TYPE Type of the load average array in the kernel.
- Must be defined unless one of
- apollo, DGUX, NeXT, or UMAX is defined;
- or we have libkstat;
- otherwise, no load average is available.
- HAVE_NLIST_H nlist.h is available. NLIST_STRUCT defaults
- to this.
- NLIST_STRUCT Include nlist.h, not a.out.h, and
- the nlist n_name element is a pointer,
- not an array.
- HAVE_STRUCT_NLIST_N_UN_N_NAME `n_un.n_name' is member of `struct nlist'.
- LINUX_LDAV_FILE [__linux__]: File containing load averages.
- HAVE_LOCALE_H locale.h is available.
- HAVE_SETLOCALE The `setlocale' function is available.
-
- Specific system predefines this file uses, aside from setting
- default values if not emacs:
-
- apollo
- BSD Real BSD, not just BSD-like.
- convex
- DGUX
- eunice UNIX emulator under VMS.
- hpux
- __MSDOS__ No-op for MSDOS.
- NeXT
- sgi
- sequent Sequent Dynix 3.x.x (BSD)

- sony_news NEWS-OS (works at least for 4.1C)
- UMAX
- UMAX4_3
- VMS
- WINDOWS32 No-op for Windows95/NT.
- __linux__ Linux: assumes /proc filesystem mounted.
- Support from Michael K. Johnson.
- __NetBSD__ NetBSD: assumes /kern filesystem mounted.
-
- In addition, to avoid nesting many #ifdefs, we internally set
- LDAV_DONE to indicate that the load average has been computed.
-
- We also #define LDAV_PRIVILEGED if a program will require
