* glibtop.h (_glibtop): New fields `error_method', `sysdeps' and
`required'. I added an improved error handling: the client can tell
the libraries which fields are absolutely required for each features
and if it fails to set one of them, this will create an error which
is handled depending upon the `error_method'.
* include/glibtop/open.h: Define some constants for `error_method'.
* lib/sysdeps.c (glibtop_get_sysdeps_r): No longer actually call any
sysdeps function, it now simply copies `server->sysdeps'.
(_glibtop_init_hook_s): Added. List of functions to be called during
`glibtop_init_s' set to `glibtop_init_<no-suid-feature>_s'.
* include/glibtop/sysdeps.h (<glibtop/union.h>): Removed.
(glibtop_init_func_t): New typedef.
(_glibtop_init_hook_s): Added.
* sysdeps/linux/*.c (glibtop_init_<feature>_s): New functions.
(glibtop_get_proc_*): Zero is now a valid pid.
* sysdeps/kernel/*.c (glibtop_init_<feature>_s): New functions.
(glibtop_get_proc_*): Zero is now a valid pid.

* include/glibtop/*.h: Using `GLIBTOP_GUILE' instead of `HAVE_GUILE'
so one should be able to use libgtop without guile in an application
even if guile is installed.
* sysdeps/common/mountlist.c: Fixed some `xstrdup' problems.
* lib/open.c: Now correctly reading server features for
`GLIBTOP_METHOD_PIPE'.
* sysdeps/freebsd: New directory.
1998-07-30 Martin Baulig <martin@home-of-linux.org>
* include/glibtop/*.h: Using `u_int64_t' instead of `unsigned long'
and `long' to avoid problems when client is on a 32bit system and
the server on a 64bit system.
1998-07-23 Martin Baulig <martin@home-of-linux.org>
* include/glibtop/procsignal.h (glibtop_proc_signal):
Changed type for `signal', `blocked', `sigignore' and
`sigcatch' to `unsigned long long'.
* Splitted `libgtop_sysdeps.la' into `libgtop_sysdeps.la' and
`libgtop_sysdeps_suid.la'.
Everything that needs to be suid/sgid is in `libgtop_sysdeps_suid.la'
and the rest in `libgtop_sysdeps.la'.
The functions from `libgtop_sysdeps_suid.la' have the `_p' prefix and
the ones from `libgtop_sysdeps.la' the `_s' prefix.
The suid library uses `glibtop_open_p' and `glibtop_close_p', the
normal one `glibtop_init_s' (found in lib/init.c), `glibtop_open_s'
and `glibtop_close_s'.
* Added `libgtop_suid_common.la' containing stuff from sysdeps/common
that is required from the suid server (currently everything from
error.c and xmalloc.c).
This means, we can add some more stuff to `libgtop_common.la' without
the risk that it may be dangerous in the suid server.
* The ``library order'' is much clearer now:
-> `libgtop.la' (from lib/) contains user-level stuff;
all functions except `glibtop_init_r' have the `_l'
suffix.
-> `libgtop_common.la' (from sysdeps/common/) contains stuff
that is common among the sysdeps directories.
use anything from `libgtop_sysdeps.la' and
`libgtop_sysdeps_suid.la'.
-> `libgtop_sysdeps.la' (from sysdeps/<sysdeps_dir>/) contains
everything from the sysdeps directory that doesn't need to
be suid/sgid.
-> `libgtop_suid_common.la' (from sysdeps/common/) is used from
the suid server instead of `libgtop_common.la'.
-> `libgtop_sysdeps_suid.la' (from sysdeps/<sysdeps_dir>/) contains
everything from the sysdeps directory that needs to be in the
suid server.
* To summarize: the server is linked only with functions that need
to be suid and everything else is linked only with functions that
do not need to be suid.

1998-07-22 Martin Baulig <martin@home-of-linux.org>
* lib/init.c (glibtop_init_s): Added this init function of
the sysdeps directory `libgtop_sysdeps.la'.
* lib/open.c (glibtop_open_l): Unconditionally calling
`glibtop_init_s' after server initialization.
* lib/lib.awk: Removed references to functions from
`libgtop_sysdeps_suid.la' to avoid undefined symbols.
* sysdeps/stub/open.c (glibtop_open_s): Renamed this
function from `glibtop_open_r'.
* sysdeps/stub/close.c (glibtop_close_s): Renamed this
function from `glibtop_close_l'.
* sysdeps/kernel/open.c (glibtop_open_s): Renamed this
function from `glibtop_open_r'.
* sysdeps/kernel/close.c (glibtop_close_s): Renamed this
function from `glibtop_close_l'.
* sysdeps/linux/open.c (glibtop_open_s): Renamed this
function from `glibtop_open_r'.
* sysdeps/linux/close.c (glibtop_close_s): Renamed this
function from `glibtop_close_l'.
* sysdeps/osf1/Makefile.am (lib_LTLIBRARIES): Added
`libgtop_sysdeps_suid.la' for the suid server.
* sysdeps/osf1/open_suid.c (glibtop_open_p): New file.
Contains all stuff that was formerly in `open.c'.
* sysdeps/osf1/open.c: Moved everything from here into
the new file `open_suid.c'.
* sysdeps/osf1/open.c (glibtop_open_s): New function.
* sysdeps/osf1/close_suid.c (glibtop_close_p): New file.
* sysdeps/osf1/close.c (glibtop_close_s): New function.
* sysdeps/osf1/*.c: Using the new init, open and close
functions.
* sysdeps/sun4/Makefile.am (lib_LTLIBRARIES): Added
`libgtop_sysdeps_suid.la' for the suid server.
* sysdeps/sun4/nosuid.c (glibtop_open_s, glibtop_close_s): New file
* sysdeps/sun4/*.c: All functions now have the `_p' suffix.
* sysdeps/common/Makefile.am (lib_LTLIBRARIES): Added
`libgtop_suid_common.la' which only contains stuff that is
needed in the suid parts.
* sysdeps/common/xmalloc.c: Using `glibtop_error_io_r' instead
of `glibtop_error_r'.
* sysdeps/{kernel, linux, osf1, sun4, stub}/init.c: Removed.
`glibtop_init_s' has been moved into `lib/init.c' since it's the
same in all the sysdeps directories.
* src/server/main.c: It is now an error to request a feature that
does not need the suid server.
* src/proxy: Removed.
1998-06-07 Martin Baulig <martin@home-of-linux.org>
* *.[ch]: Using single underscore instead of two underscores
for function prefixes (regexp: ``s,__([rspl])\b,_$1,g'') to
avoid ambiguity with mangled C++ names.
* include/glibtop/sysdeps.h: added 'dummy' member so
'GLIBTOP_SYSDEPS_<feature>' now start with 1.
* include/glibtop/*.h: we now #define 'glibtop_get_<feature>'
as 'glibtop_get_<feature>__l' and 'glibtop_get_<feature>__r'
either as the '__p' or the '__s' function.
* sysdeps/linux/*.h: added some new function suffixes:
'__l' is a function defined in the client part;
'__s' is a function defined in the sysdeps part and
'__p' is a function that needs special priviledges.
'__r' is mapped either on '__l' or on '__s'.
* sysdeps/linux/glibtop_server.h: New file -
defines system dependent constants 'GLIBTOP_SUID_<feature>'
being either 'GLIBTOP_SYSDEPS_<feature>'+1 depending upon
whether or not this feature requires using the server.
Things may now temporarily get instable; I'm currently implementing some
suggestions Sebastian Wilhelmi has made.
