===========
* We have some new ``suffix rules'':
'__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 '__p' or on '__s'.
the function without suffix is mapped on '__l'.
* We now decide at runtime whether or not using the server
is required for a particular function. All user programs
now call the '__l' function defined in '-lgtop' (in the lib
subdir). These functions either use 'glibtop_call__l' to
call the server or call the '__r' function.
* A function in the sysdeps directory now has the '__s' suffix
if it do not need any priviledges (and thus can be called directly
from client code) and the '__p' suffix otherwise (when it has to
be called from the server).
* If you call one of these functions:
-> use the '__p' suffix to be sure to get the SUID-safe one
(used in the server).
-> use the '__s' suffix to be sure to get a function that
doesn't need any priviledges.
-> use the '__r' suffix otherwise (it is mapped either on the
'__p' or on the '__s' one).
Only use the '__p' and '__s' functions in a 'GLIBTOP_SUID_<feature>'
conditional, otherwise you'll get undefined symbols !
* The server is now started from 'glibtop_init__r', but only when
it's really needed; for instance on DEC OSF/1 you only need it
for the proc* features - if you program only fetches the CPU usage,
now server will be started.
* Sorry, at the moment everything is a little bit unstable, I'm doing
heavy changes. I've just some great ideas which still need some work:
-> I want to have a SUID server that only implements those features
that need to be SUID; everything else uses the sysdeps code directly.
-> If a program only uses stuff that do not need the server, the
server will not be started at all.
-> I'm working on some kind of proxy server that can be used on a remote
host; in feature one can then use the MDI stuff from ghex in gtop to
have notebook pages displaying processes from different hosts.
* Well it is as much unstable that it only works under Linux at the moment.
1998-06-01 Martin Baulig <martin@home-of-linux.org>
* sysdeps/common/sysdeps.c: now using '__r' functions,
they are #defined either as the '__p' or the '__s' ones.
* sysdeps/linux/*.c: changed call of 'glibtop_init__r',
it now takes two additional arguments.
* examples/{first.c, second.c}: now using 'glibtop_init'
instead of 'glibtop_init__r'.
* 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.
* lib/*.c: removed #if's - we now decide at runtime
whether to use the server or to call the appropriate
function for the sysdeps directory.
1998-05-28 Martin Baulig <baulig@merkur.uni-trier.de>
* src/server/main.c: we now use the '__p' functions,
but only if the appropriate 'GLIBTOP_SUID_<feature>'
has a non-zero value.
* configure.in (@machine_incs@): always use
`-I$(top_srcdir)/sysdeps/@sysdeps_dir@'; it's no
longer conditional.
* examples/Makefile.am: removed the '_linux' examples.
* sysdeps/linux/*.c: renamed all functions implementing
features to '__s'.
* lib/*.c: renamed all functions implementing features
to '__l'; we only emit code for those functions if the
corresponding 'GLIBTOP_SUID_<feature>' has a positive value.
* include/glibtop/*.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.
* lib/sysdeps.c: removed that file; it is no longer
needed.
May/21/1998
===========
* doc/gnome-hackers.sgml: This is a short intro on how to use libgtop
in the GNOME project. It covers especially the use of its 'configure'
script and the automatically generated 'gtopConf.sh'.
May/20/1998
===========
* 'gtopConf.sh' now defines 'GTOP_LIBS' and 'GTOP_INCS' in a manner
that they contain everything that is needed to link some program with
libgtop. It will use '-lgtop' only if the server is really needed and
'-lgtop_sysdeps' otherwise;
* 'gtopConf.sh' additionally defines 'GTOP_GUILE_LIBS' and 'GTOP_GUILE_INCS'
containing everything that is needed to link some program both with
libgtop and its guile interface. They are identically to 'GTOP_LIBS'
and 'GTOP_INCS' if building the guile interface is disabled or guile
cannot be found on the system.
* 'configure' takes additional arguments '--enable-libgtop-server' and
'--disable-libgtop-server' to use the server even when it's not needed
or to disable it's use where it's needed.
* 'configure' takes an argument '--without-libgtop-guile' to disable
guile support.
* 'configure takes an argument '--without-libgtop-names' to remove
'-lgtop_names' (and '-lgtop_guile_names' when we have guile) from
'GTOP_LIBS'; in this case these libraries are not even built.
May/19/1998
===========
* Libgtop is now in the GNOME CVS Repository.
May/17/1998
===========
* we have now 'const char *glibtop_types_* []' consisting
of the C types of the corresponding files of '_glibtop_*'.
* added guile function '(glibtop-types-*)' and '(glibtop-descriptions-*)'.
May/10/1998
===========
* Port to DEC OSF1 3.0 has been made:
cpu (total, user, nice, sys, idle)
mem (total, used, free)
loadavg (loadavg)
uptime (uptime)
msg_limits (map, max, mnb, mni, tql)
sem_limits (mni, msl, opm, vmx, aem)
shm_limits (max, min, mni, seg)
The following need the server to be SUID root:
proclist (total, number, size)
procdata (cmd, state, uid, pid, ppid, pgrp, tty, k_flags,
session, tpgid, sigignore, sigcatch, signal, nice,
priority, resident, rss, vsize, utime, stime,
cutime, cstime, trs, drs)
May/07/1998
===========
* 'flags' member of sysdeps/linux/procdata.c is now
'unsigned long flags [2]'.
* When we give glibtop_get_procdata () a pid of zero, only
the flags are returned.
* We now use static constants instead of #defines for sysdeps flags.
May/03/1998
===========
* VPATH-Build now working; sometimes it's necessary to copy
$(top_srcdir)/po/cat-id-tbl.c to $(top_builddir)/po.
* The library has been tested on the following systems:
- i686-pc-linux-gnu
- sparc-sun-sunos4.1.1
- alpha-dec-osf1 (that's DEC OSF1 3.0 and 3.2)
* Compilation has been tested on the following systems (I have no root
access there and cannot test the library because of this):
- sparc-sun-solaris2
- i386-bsdi
* Does no longer require Gnome.
* Guile-Parts are compiled only if guile can be found.
* Some of the executables are statically linked to copy them more easily
between machines.
May/02/1998
===========
* Global changes to the interfaces, all functions except glibtop_open()
and glibtop_close() that took a server argument have now a '__r' suffix;
the original name is now a macro that uses glibtop_global_server.
Apr/10/1998
===========
Added new directory sysdeps/guile/names. It is the guile interface
to the gtop_names library found in sysdeps/names. Changed
GLIBTOP_DESCRIPTIONS to GLIBTOP_NAMES and added GLIBTOP_GUILE_NAMES
to the header files.
Apr/09/1998
===========
Added new directories guile and names to sysdeps. In names are
some string constants about the data stored in the structures.
guile is a guile interface for the library. It is used in
examples/third (which has been completely rewritten).
The header files define things from names when GLIBTOP_DESCRIPTIONS
if defined and/or from guile when HAVE_GUILE is defined.
Apr/08/1998
===========
Added guile wrapper for the library (see examples/third).
