Dear all
The X2Go project is proud to announce a new release of the X2Go
component ,,x2goserver''.
New gains of this version of ,,x2goserver'' are:
o respect the NoDisplay and Hidden values in .desktop files, thanks to Jason
Alavaliant
o x2gocleansessions rewritten - it now shouldn't be suspending sessions with
no good reason anymore
o randomize nxagent port, based on Robert Nowotny's SSH_PORT patch
o remove Blowfish cipher when mounting remote sshfs endpoints - fixes file
file sharing issues
o the xsession-x2go-errors file now contains the hostname and is rotated once
o X2GO_XSESSION feature output now captured thanks to Tor Perkins
o various other bugfixes and improvements
The X2Go project thanks Jason Alavaliant, Henning Heinold, Robert Nowotny, and
Tor Perkins for their valuable input and submitted work.

.
[ Mihai Moldovan ]
* New upstream version (4.0.1.20):
- x2goserver/bin/x2gogetapps: respect NoDisplay and Hidden values, don't
parse the full desktop file if there are non-Desktop Entries groups.
Based on a patch submitted by Jason Alavaliant. Fixes: #812.
- x2goserver/bin/x2gogetapps: do not print spurious newlines.
- Change string "X2go" to "X2Go" where appropriate.
- Add runcommand.d hooks to x2goserver-extensions Makefile.
- x2goserver/bin/x2gosessionlimit: don't iterate over the whole groups
file. Only check the primary and secondary groups as returned by
getgid()/getgroups(). Fixes long delays in session startup on machines
with a gazillion of groups.
- x2goserver/sbin/x2gocleansessions: re-fetch the current sessions' status
before handling it. Using the "cached" value from the initial
x2golistsessions run may be desynchronized with the actual current
value. Avoids a race condition logging users out after they attached to a
session.
- x2goserver/sbin/x2gocleansessions: rename %remembered_sessions_since to
%remembered_sessions_status_since. That's what it really is. Add
comments to further clarify what it's actually doing. Change it to
include a timestamp instead of the "iteration count multiplied by two"
value. Compare timestamps to see if killing hanging nxagent processes is
necessary.
- x2goserver/sbin/x2gocleansessions: rename
%remembered_sessions_status_since to
%remembered_sessions_status_since_time. Add
%remembered_sessions_status_since_iterations that will come in handy for
the next change.
- x2goserver/sbin/x2gocleansessions: give suspended-but-running sessions a
grace period of one iteration. Fixes: #888.
- x2goserver/sbin/x2gocleansessions: fix ugly missing whitespace.
- x2goserver/sbin/x2gocleansessions: move up session status sync a bit,
don't update session state when session has been removed from the
database.
- x2goserver/sbin/x2gocleansessions: unify log messages. Move dangling
line around.
- x2goserver/sbin/x2gocleansessions: whitespace only.
- x2goserver/sbin/x2gocleansessions: also delete entries in the other,
overlooked hashes.
- x2goserver/sbin/x2gocleansessions: move socket and lock file cleanup
into time-based block for finished/failed sessions.
- x2goserver/sbin/x2gocleansessions: add @remembered_finished_sessions
array. Merge with session list as queried from the database (won't
include finished/failed sessions) and remember F-state sessions via this
array. Only delete elements once work on these has been finished.
- x2goserver/sbin/x2gocleansessions: don't add failed/finished sessions to
remembered list if that list already includes them.
- x2goserver/sbin/x2gocleansessions: don't use gmtime (time ()) but merely
time (). The former one returns a formatted date-time string, which
can't be checked by forming a difference. The latter one returns an UNIX
timestamp, which is what we really want... minus leap seconds. Let's
hope this doesn't bite back some time or later...
- x2goserver/sbin/x2gocleansessions: add debugging output to show the
state change when updating the cached state result.
- x2goserver/sbin/x2gocleansessions: only output status refreshing debug
message if the old and new states actually differ. Prevents log spam.
- x2goserver/bin/x2gostartagent: changes to Robert Nowotny's SSH_PORT
patch. Fixes: #922. Use default outgoing interface to determine IP
address. Use the whole range of ${RANDOM}'s pool. Seed it for good
measure. Change the default method to randomization instead of IP-based
initialization. If IP-based initialization was requested but the default
outgoing IP address unavailable, fall back to randomization.
- x2goserver/bin/x2goruncommand: whitespace and comment changes only.
- x2goserver/bin/x2gocleansessions: replace system_capture_stdout_output()
with actual implementation. We don't have that function on the release
branch.
- x2goserver-xsession/etc/Xsession: use /bin/bash explicitly on RedHat-,
Gentoo- and SuSE-based systems. Users might change /bin/sh to point to a
shell like mksh or dash, which do not support the -l or -c flags to
exec. C.f., BGO #575022 (Gentoo.)
- x2goserver/bin/x2gomountdirs: remove blowfish Cipher spec hardcoded for
sshfs mounts. The speed improvement is probably mostly an illusion
(unless talking about high-bandwidth links) and more importantly recent
OpenSSH server versions seem to disable the Blowfish cipher by default,
leading to errors like "Connection reset by peer."
- x2goserver/bin/x2goruncommand: whitespace only.
- x2goserver/sbin/x2gocleansessions: add Perl documentation and --help,
-h, -? and --man options. Fixes: #1065. Also print a usage message on
unknown options.
- x2goserver/man/man8/x2gocleansessions.8: drop obsolete man page.
- x2goserver-xsession/etc/Xsession: fix uname calls when (potentially)
creating session log/error file and add uname call where necessary.
- x2goserver-xsession/etc/Xsession: include hostname in
xsession-x2go-errors file name. Part of #923.
- x2goserver-xsession/etc/Xsession: rotate old log/error file before
appending new data. Fixes: #923.
- x2goserver-xsession/etc/Xsession: fix wrong variable usage.
Fixes: #1073.
- x2goserver/sbin/x2gocleansessions: move in-file POD to end of file,
rather than "commenting" out all the remaining code. Fixes: #1068.
- x2goserver/sbin/x2godbadmin: exit earlier when not finding the required
"x2gouser" user.
* x2goserver.spec:
- Add sudo and logcheck as BuildRequires and Requires. Don't own
directories that are owned by sudo and logcheck. Logcheck is not
available on *SUSE, FC < 20 and RHEL, so for those distros still own the
directories.
- Typo fix in comment: Recommands -> Recommends.
- Fix installation on OpenSUSE 12.3 and higher: has replaced pwdutils with
shadow. Also affects SLE{S,D} 12.
- Add workaround documentation for sudoers on *SUSE 11.
- Add shadow/shadow-utils/pwdutils Requires to x2goserver-printing
sub package.
- Add new dependency on bash.
- Add new dependency on xkeyboard-config to x2goserver. Fixes: #903.
- Add new dependency on perl and the Cwd module to x2goserver-xsession.
Part of #923.
* debian/control:
- Add new dependency on bash.
- Add new dependency on xkb-data to x2goserver.
- Maintainer change in package: X2Go Developers <x2go-dev(a)lists.x2go.org>.
- Uploaders: add myself. Also, force a rebuild due to the changed
versioning.
- Add new dependency on perl-modules for Cwd. Part of #923.
.
[ Henning Heinold ]
* New upstream version (4.0.1.20):
- x2goserver/sbin/x2godbadmin: remove trailing whitespace.
- x2goserver/sbin/x2godbadmin: revoke all PRIVILEGES before trying to
delete a user on postgres. Fixes: #889.
.
[ Mike Gabriel ]
* debian/x2goserver.preinst:
+ Use proper comment header explaining about preinst script argument
calls (not postinst).
.
[ Robert Nowotny ]
* New upstream version (4.0.1.20):
- x2goserver/bin/x2gostartagent: original patch for SSH_PORT
randomization/IP-based initialization. Submitted as #922.
.
[ Stefan Baur ]
* New upstream version (4.0.1.20):
- x2goserver/bin/x2goruncommand: add the other trinity launcher scripts in
order from newest to oldest. Fixes: #985.
.
[ Tor Perkins ]
* New upstream version (4.0.1.20):
- x2goserver/bin/x2goruncommand: capture x2goruncommand debug output for
x2gofeature X2GO_XSESSION.
.
[ Orion Poplawski ]
* New upstream version (4.0.1.20):
- x2goserver/bin/x2golistdesktops: drop -u parameter to ss. Fixes: #799.
We would filter out UDP sockets later anyway and the combination -lxu is
known to be broken with some versions of iproute2.

Mihai Moldovan
