+1998-07-18  Martin Baulig  <martin@home-of-linux.org>
+
+	* lib/{init, open}.c: Added `GLIBTOP_METHOD_PIPE' again.
+	
+	* src/server/main.c: Removed gettext stuff.
+
+1998-07-17  Martin Baulig  <baulig@Stud.Informatik.uni-trier.de>
+
+	* sysdeps/common/sysdeps.c (glibtop_get_sysdeps_r): Using
+	library functions with '_l' prefix instead of directly calling
+	sysdeps code with '_r' prefix. This is necessary for client/server
+	mode.
+	
+	* lib/lib.awk (glibtop_get_*): Now correctly using
+	`(1 << GLIBTOP_SYSDEPS_*)' instead of `GLIBTOP_SYSDEPS_*'.
+	
+	* sysdeps/sun4/proclist.c (glibtop_get_proclist_p): Added
+	implementation of that feature.
+
+	* sysdeps/sun4/proc_{uid, state}.c: Now working quite well.
+
+	* sysdeps/sun4/proc_{mem, time, signal, kernel, segment}.c: Added
+	some basic implementation; this isn't really working yet.
+	
+	* sysdeps/linux/sem_limits.c: Applied patch from Albert K T Hui

+	implementation of that feature.
+
+	* sysdeps/sun4/{shm_limits.c, msg_limits.c, shm_limits.c}:
+	Added implementation of this features.
+
+1998-07-14  Martin Baulig  <baulig@Stud.Informatik.uni-trier.de>
+
+	* src/daemon/server_config.h.in: Added some comments.
+	
+	* src/daemon/server_config.pl: New file. This is a script you can use
+	to create `server_config.h'. It will query you for some configuration
+	options.
+
+	* configure.in (AC_PROG_AWK): Replaced this test with explicit test
+	for `gawk' and `awk' since `mawk' doesn't work.
+
+1998-07-14  Martin Baulig  <martin@home-of-linux.org>
+
+	* src/daemon/gnuserv.c: Doing correct server initialization
+	using `glibtop_set_parameter_l' and `glibtop_init_r'.
+
+	* src/daemon/main.c: Removed call to `glibtop_init_r'.

+	* sysdeps/{linux, sun4, stub}/open.c: No longer `memset'
+	server to zero.

+
+	* kernel.patch: Patch for the Linux kernel to add the
+	new system call.

kernel/README

@@ -0,0 +1,21 @@
+This is a new system call `table ()' for the Linux table. It is faster
+than reading from /proc and can be used to fetch all information required
+for libgtop until whe have some other function (extended sysctl, ...) in
+standard kernels.
+
+I didn't want to change sysctl or some other function myself cause this may
+cause other applications relying upon those function to fail. This is
+something for the ``real'' kernel gurus ...
+
+To use this new system call for libgtop, do the following:
+
+* Copy this directory to /usr/src/linux/table
+* Make /usr/src/linux/include/linux/table.h symlink to /usr/src/linux/table/table.h
+* Apply the patch `kernel.patch' to the kernel, compile, install and reboot
+* Recompile libgtop (remove `config.cache' and run the `autogen.sh' again).
+
+If you want to change and/or add something - feel free to do so !
+
+Have fun,
+
+Martin

+mult_lvl_cmp:
+    slick general purpose multi-level compare function I invented.
+sort_depth:
+    the number of levels of functions *to use*.  This means many more levels
+    can be defined than mult_lvl_cmp tres out.  If this is 1 then mult_lvl_cmp
+    is just a trivial wrapper around (*sort_function[0]).
+sort_direction:
+    multiplicative factor for the output of cmp_whatever.
+    1 ==> default order, -1 ==> reverse order, 0 ==> forced equality
+    The 0 bit is the neat part.  Since a value of zero is the code for equality
+    multiplying the output of cmp_foo(a,b) forces a==b to be true.  This is a
+    convenient way to turn sorting off in middle levels of a multi-level sort.
+    If time is a problem, reforming the whole sort_function array to not include
+    these unsorted middle levels will be faster since then cmp_foo won't even
+    be called.  It might simplify some code depending upon how you organize it.
+sort_function[]:
+    array of function pointers that points to our family of comparison functions
+    (I have named them cmp_* but mult_lvl_cmp doesn't care what they're named).
+    This may be declared and initialized like so:
+       int (*sort_function[])(void* a, void* b)={&cmp_foo, &cmp_bar, &cmp_hiho};
+    You could also use my command line '-O' parser below.
+
+Note that we only descend levels until the order is determined.  If we descend
+all levels, that means that the items are equal at all levels, so we return 0.
+Otherwise we return whatever the level's cmp_foo function would have returned.
+This allows whatever default behavior you want for cmp_foo.  sort_direction[]
+reverses this default behavior, but mult_lvl_cmp doesn't decide that ascending
+or descending is the default.  That is the job of your cmp_foo's.

+Using this program on over 700 files in /dev to perform number->name resolution
+took well under 300 microsecs per device number pair on a Pentium 90.  It is
+somewhat tough to time because once the 3 pages have been mapped in, the time is
+almost zero.  For things like top, this method may even be faster in the long
+run.  Those interested can gprof it for me.  This system has the virtue of being
+nearly perfectly adaptable to individual systems, self updating when /dev
+changes and pretty darn fast when it hasn't.  It will be slow for users without
+perms to change the psdevtab file, though.  So this is what I decided was
+reasonable.  If the process does not have perms to create or update
+/etc/psdevtab and it is out of date, we try /tmp/psdevtab.  If /tmp/psdevtab is
+either out of date or unreadable (malicious user creates it and chmods it),
+$HOME/.psdevtab is used.  This secondarily allows for per-user naming of ttys,
+but is really so that at most one user sees only a single delay per /dev
+modification.
+
+To do the timings I did something like this with zsh:
+    a=(`ls -l *(%^@/) | awk '{print $5 $6}' | sed 's/,/ /'`);
+    time ./test $a
+
+Finally, for lack of a better file for these to be in, I have collected the
+old algorithmic device number <-> device name mappings.

+    devno = m<<8 + n , m = devno>>8 , n = devno && 0x00FF, and let
