X2Go Server (4.1.0.0) released

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 Reimplemented database support and some core server functionality as Perl modules. o Add new x2golistshadowsession support. o New support for SupeReNicer - a feature that automatically renices sessions upon disconnects/resumes. Disabled by default. o Add new support for TeleKinesis - a feature for embedding windows into X2Go sessions, especially useful for video playback. This feature is currently stale. o Split up Debian packaging into more packages. o Support nx-libs 3.5.99.x. o Rework session startup and resuming scripts. o Improved DEB and RPM packaging, including debconf notices when updating on Debian-based platforms.

*** IMPORTANT INFORMATION ***

This X2Go Server release depends upon the new nx-libs versions 3.5.99.5 and higher (at the time of writing, 3.5.99.14 has been released as the new stable version in our repositories).

It will NOT work correctly with the legacy 3.5.0.x version of nx-libs.

For Xinerama to work (at all), you will need X2Go Client version 4.1.1.1 or higher. Older versions will work in general, but not provide Xinerama support.

Additionally, please make sure to merge your configuration files.

*** IMPORTANT INFORMATION ***

The X2Go project thanks Guangzhou Nianguan Electronics Technology Co. Ltd., Otto Kjell, Orion Poplawski, Mark Pederson-Cook, Kaan Ozdincer and Martti Pitkänen for their valuable input and submitted work.

X2Go Component: x2goserver Version: 4.1.0.0.2 Status: RELEASE Timestamp: 1518732228 Date: Thu, 15 Feb 2018 23:03:48 +0100 Fixes these bug report(s): 82 86 102 117 121 371 557 575 1047 Changes: x2goserver (4.1.0.0.2) RELEASED; urgency=low . [ Mike Gabriel ]

• Bump development upstream version to 4.1.0.0.
• New upstream version (4.1.0.0):
  • Transform x2gologlevel.pm into proper Perl module X2Go::Log.
  • Transform x2godbwrapper.pm into proper Perl module X2Go::Server::DB.
  • Transform x2gosqlitewrapper.pl into small wrapper script and move the SQLite3 into Perl package X2Go::Server::DB::SQLite3.
  • Move x2gosqlitewrapper into Perl package X2Go::Server::DB::SQLite3.
  • Move PostgreSQL DB code into Perl package X2Go::Server::DB::PostgreSQL.
  • Move X2Go SQL configuration files (/etc/x2go/x2gosql) into package libx2go-server-db-perl.
  • Install /etc/x2go/x2go_logout with its directory x2go_logout.d via Makefile installation.
  • Fix new SQLite3 wrapper for db_getmounts Perl call.
  • Fix list output in new SQLite3 wrapper.
  • Make session type label XFCE a valid session that starts xfce4-session.
  • Fix failures of x2gogetagent that was related to faulty regexp in SQLite3 DB wrapper script.
  • Add X2Go Server feature X2GO_LIST_SHADOWSESSIONS.
  • Break execution of x2gosuspend-session / x2goterminate-session if the script is called without session as first argument and $X2GO_SESSION not set. (Fixes: #82).
  • Make x2goruncommand aware of the Cinnamon desktop shell. (Fixes: #117).
  • Fix build-arch target in x2goserver/Makefile. (Fixes: #121).
  • Load config files from a Perl package (X2Go::Config).
  • Disable SupeReNicer by default.
  • Fix session handling for cross-user-account desktop sharing. Now session names of desktop sharing session start with the username of the user who is requesting the desktop sharing, rather than the username of the person who shares his/her desktop.
  • Do not superenice desktop sharing / shadow sessions.
  • Drop obsolete components x2goserver-compat, x2goserver-pyhoca.
  • Makefile: pre-set the PERL_INSTALLDIRS var with ,,vendor''. Use pure_install rather than install.
  • Avoid one argument system calls in x2golistshadowsessions.
  • Provide Perl functions to capture stdout/stderr with multi-argument system calls.
  • Avoid one argument system calls and backticks in SupeReNicer.
  • Handle situations in SupeReNicer where the agent PID is not set.
  • Start working on an abstraction layer (as Perl package X2Go::Server::Agent) that handles all (NX) agent specific actions. Move duplicate code into that new Perl package.
  • Security audit of complete code tree, avoid one-argument system calls where possible, avoid backticks, use more quotes in shell scripts.
  • Add tunneling port allocation for TeleKinesis framework.
  • Only use teki_* fields with PostgreSQL DB backend if TeKi is enabled.
  • Provide --updatedb feature in x2godbadmin if DB backend is PostgreSQL.
  • Execute post-start.d extension scripts _after_ the session information has been submitted to the session DB. This allows execution of x2golistsessions and other X2Go commands in post-start.d extension scripts.
  • Re-arrange parameter order of x2gocreatesession and related DB functions. Make sure the session ID comes first and we have only optional parameters towards the end of the parameter array.
  • Fix accessing ARGV in X2Go::Utils:check_x2go_sessionid sub. (Fixes: #575).
  • Fix TeKi storing Telekinesis ports in PgSQL-based session DB. Allow negative port numbers for the case that Telekinesis is not installed.
  • Fix db_insertmount (SQLite). Pathnames must not be enclosed by parentheses.
  • Make sure to return "1" in X2Go::Server::DB Perl functions that don't return anything by default.
  • Make it possible to change the state of shadow sessions.
  • Provide --debug option for x2gocleansession that allows running x2gocleansessions in foreground (and in debug mode).
  • Properly clean up shadow sessions for the session database.
  • Move x2goagent wrapper package around nxagent into X2Go Server. (Fixes: #1047).
  • Update execution logic of the x2goagent wrapper script. The script now sets the env var $NXAPP and then calls the nxagent wrapper script. For this to work properly, the x2goagent symlinks has to be placed into directory where the nxagent executable is installed ($LIBDIR/nx/bin/, normally).
  • Revisit packaging for latest change in x2goserver-x2goagent. Don't inject $(LIBDIR) rather than injecting $(NXLIBDIR) via debian/rules and x2goserver.spec.
  • x2goagent wrapper script: Use exec command to launch nxagent. Put "$@" in quotes.
• debian/control:
  • Package X2Go::Log in separate package: libx2go-log-perl.
  • Package X2Go::Server::DB in separate package: libx2go-server-db-perl.
  • x2goserver package: Depend on libx2go-log-perl, libx2go-server-db-perl.
  • Move x2goserver.conf into separate package: x2goserver-common.
  • Use Breaks/Replaces to exchange x2goserver.conf in x2goserver package by x2goserver.conf in new x2goserver-common package.
  • Move several x2goserver-* package to x2goserver's Recommends field.
  • Add Reinhard Tartler to Uploaders.
  • Add libcatpure-tiny-perl to Depends: field of libx2go-server-perl.
  • Move x2gosql config to x2goserver-common.
  • Several style and dependency fixes. Use Conflicts: instead of Breaks: for unversioned package conflicts.
  • Test if telekinesis-server is installed server-side. If so, prepare the telekinesis session sub-directory.
  • Add D (bin:package libx2go-server-db-perl): libswitch-perl.
  • Fix B/R for x2goserver-x2goagent. We need to break/replace x2goagent (<< 3.5.99.2~).
  • Nooo... we need to break/replace x2goagent (<< 2:3.5.99.2~).
• debian/x2goserver.postinst, debian/libx2go-server-db-perl:
  • Handle X2Go session DB creation in x2goserver _and_ perl-X2Go-Server-DB on postinst.
  • Make sure X2Go session DB files get updated during postinst.
• debian/libx2go-server-db-perl installation scripts:
  • Remove dpkg-statoverride during remove on prerm, not on purge in postrm.
• debian/x2goserver.init:
  • Rely on $PATH when invoking x2gocleansessions.
• debian/x2goserver.service:

• debian/copyright:
  • Provide DEP-5 compliant copyright file.
  • Add copyright.in auto-generated file (by licensecheck+CDBS) for later reference.
• debian/x2goserver-x2goagent:
  • Make sure the .features file for x2goserver-x2goagent ends up in its bin:pkg.
• x2goserver.spec:
  • Bring debian/control and x2goclient.spec in sync.
  • Make sure x2godbadmin is evoked from package x2goserver.
  • Handle X2Go session DB creation in x2goserver _and_ perl-X2Go-Server-DB on postinst.
  • Set buildroot if we build for EPEL-5.
  • Use deprecated %{_initrddir} macro for EPEL-5 builds.
  • Take advantage of native RHEL support (since 4.0.1.10).
  • Install SQLite3 wrapper as setgid x2gouser. (Fixes: 371).
  • Assure that SQLite3 session DB file gets created on install (unless PostgreSQL is used as session DB backend).
  • Make sure x2goserver-*.features files do not get installed multiple times into various packages.
  • Make sure X2Go Server (x2gocleansessions) starts after installation.
  • Make sure X2Go session DB files get updated during postinst.
  • Require Perl(Switch) (bin:package x2goserver).
  • Don't fail in %post during X2Go session DB creation.
  • Fix call of x2godbadmin --updatedb during package upgrade.
  • Hand over %{_prefix}/%{_libdir}/nx as $NXLIBDIR to x2goserver's Makefiles. Required for x2goagent symlink to be properly installed into the same folder where the nxagent executable gets installed.
  • Also hand over %{_prefix}/%{_libdir}/nx as $NXLIBDIR when executing make install.

• x2goserver.spec:
  • Fix NXLIBDIR path to use %{_libdir} directly. . [ Oleksandr Shneyder ]
• New upstream version (4.1.0.0):
  • Fix x2godbadmin. Set right column name "tekidata_port" in create table. (Fixes: #557).
  • Unset LD_LIBRARY_PATH for the case when x2gostartagent started from x2godesktopsharing. . [ Mark Pederson-Cook ]
• debian/po:
  • Translate DebConf templates to Danish. . [ Kaan Ozdincer ]
• debian/po:
  • Translate DebConf templates to Turkish. . [ Mihai Moldovan ]
• New upstream version (4.1.0.0):
  • x2goserver/sbin/x2gocleansessions: add timestamp to debug output.
  • x2goserver/sbin/x2gocleansessions: also (correctly) log to syslog if started with --debug parameter.
  • libx2go-server-db-perl/lib/libx2go-server-db-sqlite3-wrapper.pl: don't use deprecated defined (@array) construct which never really did what one would expect (defined () can only be used on scalar values.)
  • x2goserver/bin/x2gofeaturelist: whitespace only.
  • x2goserver-x2goagent/: rename share/x2go/rgb back to etc/rgb.
  • x2goserver-x2goagent/Makefile: install etc/rgb as in ${SYSCONFDIR}/x2go/rgb again and create a symlink from that to ${DATADIR}/x2go/rgb.
  • x2goserver-x2goagent/Makefile: fix left-over reference to share/x2go/rgb. It's back to etc/rgb now.
  • x2goserver-x2goagent/share/x2go/x2gofeature.d/: rename x2goserver-agent.features to x2goserver-x2goagent.features.
  • x2goserver/sbin/x2gocleansessions: add -d short parameter for enabling debugging capabilities to POD.
  • README.md: whitespace fixes and typo correction.
  • X2Go/Server/DB/SQLite3.pm: fix command name in error messages.
  • X2Go/Utils.pm: backport user name regex changes.
  • x2goserver-x2goagent/etc/x2goagent.options: reenable XFIXES extension.
  • x2goserver/bin/x2gostartagent: fix most other shellcheck warnings, more quotes, curly braces et. al.
  • x2goserver/bin/x2goresume-session: fix most other shellcheck warnings, more quotes, curly braces et. al.
  • x2goserver/lib: add new perl wrapper script for X2Go::Utils::is_true called x2goistrue.
  • x2goserver/bin/x2gostartagent: replace inline perl with calls to x2goistrue and x2goqueryconfig.
  • x2goserver/bin/x2gostartagent: support disabling or enabling RANDR Xinerama in x2goagent via any parameter in the form randr_xinerama=value (with value interpreted by x2goistrue). Note that it is not possible to change the RRXinerama preference after a session has been started currently.
  • x2goserver/bin/x2gostartagent: pass in xinerama configuration value via environment. Doing it via an argument is just asking for trouble since we actually have optional parameters.
  • x2goserver/bin/x2gostartagent: add FIXME entry for the SHADREQ_USER optional parameter. No client actually uses it and it makes the whole parameter handling fragile.
  • x2goserver/bin/x2go{startagent,resume-ression}: instead of disabling RANDR Xinerama if no xinerama support has been requested, switch to modifying the xinerama nx/nx option. For x2gostartagent, that means a variable rename from X2GO_RANDR_XINERAMA to X2GO_XINERAMA with essentially the same semantics. For x2goresume-session, a new parameter is added.
  • x2goserver/bin/x2gostartagent: disable Xinerama support by default, more compatible with the old behavior (and python-x2go/PyHoca).
  • x2goserver/bin/x2go{resume-session,runcommand}: drop obsolete and now-unused NX_XINERAMA_CONF variable.
  • x2goserver/lib/x2gogetrandomport: fix function name, leading to startup failures.
  • x2goserver/lib/x2go{check,getfree}port: parameter expansion and single quotes don't mix well. Use double quotes instead.
  • x2goserver/lib/x2gocheckport: fix X2GO_LIB_PATH -> x2go_lib_path typo.
  • x2goserver/bin/x2gostartagent: output variable expects a string, not an integer.
  • x2goserver/lib/x2goistrue: perl strips empty parameters from @ARGV, so work around that gracefully.
  • x2goserver/lib/x2goistrue: use shift unconditionally and check the parameter to be defined instead.
  • x2goserver/bin/x2goresume-session: handle missing xinerama parameter in options string gracefully, skipping that part (and the other optional geometry string) correctly.
  • x2goserver-common/Makefile: whitespace (lineup) only.
  • */man/*/*: update dates and version in manpages.
  • */VERSION.*: remove -preview tag.
• x2goserver.spec:
  • Only create session DB in x2goserver's post install script. Do use proper Requires(post) statements to make sure perl-X2Go-Server-DB and x2goserver-common are available when x2goserver's post install script is being executed. Fixes installation bugs reported by Michael DePaulo.
  • Add support for %{_datadir}/applications symlink in %{_sysconfdir}/x2go.
    • Add creation and deletion bits to %post and %preun scriptlets.
    • Refactor %post, %pre, %postun and %preun scriptlets to accommodate for last change.
    • Don't use %{_sbindir} for chkconfig and service on SLE{S,D}. %{_sbindir} is a macro for /usr/sbin/, whereas chkconfig and service reside in /sbin/.
  • Change deprecated and removed PreReq to Requires(pre) header.
  • Move shadow/shadow-utils/pwdutils Requires to x2goserver-common sub package (where they are actually needed.)
  • Re-add etc/rgb as a config file.
  • Correctly create and specify the x2goserver-x2goagent subpackage, instead of a standalone x2goagent package.
  • Fix dependency upon versioned nxagent.
  • Let x2goserver depend upon x2goagent-virtual, add Provides: keyword to x2goserver-x2goagent (also need to be implemented within X2Go's nx-libs master branch.)
  • Add script/symlink ${LIBDIR}/x2go/bin/x2goagent to installed file list.
  • Split up x2gosql installed file list part into actual directories and files.
  • Disable stale symlinks check for now (and add comment to re-enable it once we've switched to nx-libs 3.5.99 or higher for good.)
  • Actually export NO_BRP_STALE_LINK_ERROR in a correct way/with the correct value. Never blindly trust the internets if something looks odd.
  • Add %{_libdir}/x2go/bin as owned directory for x2goserver-x2goagent. Also owned by the alternative package x2goagent in nx-libs.
  • Exclude %{_bindir}/x2goagent from being packaged into x2goserver package.
  • x2goserver-x2goagent needs nxagent 3.5.99.3 and higher.
  • Actually add logcheck Requires.
  • Give the x2goagent-virtual package a specific version, derived from the x2goserver version.
  • Let x2goserver-x2goagent conflict with the former x2goagent package.
  • Let x2goserver depend upon its own x2goserver-virtual package for now. The release after that can drop the virtual package again.
  • Add x2goistrue to %files section.
  • Remove useless x2goagent-virtual Provides: and let x2goserver-x2goagent obsolete older x2goagent packages.
• debian/control:
  • Maintainer change in package: X2Go Developers <x2go-dev@lists.x2go.org>.
  • Depend upon newer x2goagent package that now provides the x2goagent.options file.
  • Fix nxagent dependency. Must be version 3.5.99.3 or higher. Epoch was missing.
  • Dip into cold water and depend solely upon x2goserver-x2goagent in a versioned fashion.
• debian/:
  • Remove x2goserver-x2goagent.dirs and hope it's really unneeded, because the Makefile creates these directories correctly.
• debian/x2goserver-x2goagent.install:
  • Re-add etc/rgb file. . [ Martti Pitkänen ]
• debian/po:
  • fi.po: update Finnish DebConf templates translation.
