[bug#27356] [PATCH 0/1] gnu: Add gnome-planner.

[Chris Marusich]

Hi,

This patch adds GNOME Planner, a project management tool.  I've
verified that it builds and that it's usable on GuixSD.  Some features
are disabled by default (e.g., the database integration).  I've
disabled the Python bindings explicitly because it turned out to be
non-trivial to build that, and I don't need the Python bindings at
this time.  Here's a summary of the optional features, taken from the
build log:

    Build API docs               : no
    Python bindings              : no
    Python plugin                : no
    Simple priority scheduling   : no
    Database/GDA support         : no, 
    Evolution Data Server import : no
    Evolution Data Server backend: no

I didn't test everything, but I verified that the following things
worked:

    * The built-in help browser correctly displays the manual.
    * Save a file, open a file.
    * Print to PDF, print to PostScript, export to HTML.
    * Add tasks and resources, and customize their attributes.
    * Assign tasks to resources, and establish task predecessor
      relationships.
    * All the views - Gantt, task, resource, resource utilization.
    * Calendar creation and modification.

Along the way, I noticed some errors, but as far as I could tell,
these errors did not stop the software from functioning.  I'll list
the errors below for completeness.  Maybe somebody will know what to
do about some of them.

During the build, there were lots of messages like this (one for each
locale or translation, I guess):

    WARNING: failed to install schema
    `/schemas/apps/planner/views/resource_view/print_enabled', locale
    `ast': Unable to store a value at key
    '/schemas/apps/planner/views/resource_view/print_enabled', as the
    configuration server has no writable databases. There are some
    common causes of this problem: 1) your configuration path file
    /gnu/store/vnqdzjkfwlp0zgs4f9vqfi56g7vav206-gconf-3.2.6/etc/gconf/2/path
    doesn't contain any databases or wasn't found 2) somehow we
    mistakenly created two gconfd processes 3) your operating system
    is misconfigured so NFS file locking doesn't work in your home
    directory or 4) your NFS client machine crashed and didn't
    properly notify the server on reboot that file locks should be
    dropped. If you have two gconfd processes (or had two at the time
    the second was launched), logging out, killing all copies of
    gconfd, and logging back in may help. If you have stale locks,
    remove ~/.gconf*/*lock. Perhaps the problem is that you attempted
    to use GConf from two machines at once, and ORBit still has its
    default configuration that prevents remote CORBA connections - put
    "ORBIIOPIPv4=1" in /etc/orbitrc. As always, check the user.*
    syslog for details on problems gconfd encountered. There can only
    be one gconfd per home directory, and it must own a lockfile in
    ~/.gconfd and also lockfiles in individual storage locations such
    as ~/.gconf

The above message seems related to another error I saw, which always
gets emitted when starting the application from the command-line:

    GConf Error: Failed to contact configuration server; the most
    common cause is a missing or misconfigured D-Bus session bus
    daemon. See http://projects.gnome.org/gconf/ for
    information. (Details - 1: GetIOR failed:
    GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name
    org.gnome.GConf was not provided by any .service files)

I noticed the following error while modifying the predecessor for a
task (in the "Edit task properties" window):

    (planner:32632): GLib-GObject-CRITICAL **: Object class
    PlannerPopupEntry doesn't implement property 'editing-canceled'
    from interface 'GtkCellEditable'

I noticed (when creating a new, empty calendar) the following error
when applying the changes to a day's hours (via the following button:
Project > Manage Calendars > (Calendar Editor) Default week... >
Apply):

    ** (planner:32632): CRITICAL **: mrp_day_get_id: assertion 'day !=
    NULL' failed

And on another occasion (I can't remember what I was doing which
caused it), I noticed the following error:

    (planner:32431): libglade-WARNING **: Could not load support for
    `gnome': libgnome.so: cannot open shared object file: No such file
    or directory

I also noticed some graphical errors every now and then.  For example,
while zooming in/out, the Gantt chart view sometimes fails to render
either partially or wholly, but usually it looks just fine.  Various
other sections of the UI exhibit similar behavior infrequently.  Since
I personally observe a similar kind of issue with my graphical Emacs
on GNOME3 already, I have no reason at this time to suspect that this
is an issue limited to the GNOME Planner application.

Also, the "Zoom to fit the entire project" button doesn't always seem
to zoom correctly; sometimes it leaves part of the project out of
view.  This is a minor nuisance, but I don't know if it's a
GuixSD-specific problem.

Finally, the build is non-deterministic.  I looked into this briefly
and found that at least one of the causes is because, for some
dependencies (e.g., GIO), the retained store path is not always the
same.  This suggests that perhaps those dependencies themselves do not
build deterministically.

Despite all of these issues, as far as I could tell, the Planner
application still worked just fine.
