Desktop app maintainers: Please check for StartupNotify=true

[Colin Walters]

Hi,

For GNOME 3 to more reliably do application tracking, we will be
associating through startup-notification.  Some background here:

http://lists.freedesktop.org/archives/xdg/2010-February/011321.html

However for startup notification to work, for compatibility reasons,
the upstream .desktop file must have StartupNotify=true.  It's come to
my attention that a lot of .desktop files are missing this, even
though they use GTK+.  I've written a quick script which heuristically
examines installed apps (attached); if someone writes the script which
checks the whole repository, that'd be cool.

If you maintain a desktop app, please check for StartupNotify=true,
and if your app uses GTK+ or Qt, then please submit a patch *upstream*
to add it, and at your option apply that patch in Fedora.

Here's sample output from the script on my workstation, which shows a
vast swath of system-config-* missing it; others of these are false
positives since they're not user-visible apps.

Hmmm, I'm certain we've had this in the guidelines (or in the Wiki or in
the old QA Checklist) several years ago, including help on how to
determine the StartupWMClass= name if necessary.

Currently can only find:
https://fedoraproject.org/wiki/Packaging:Guidelines#Desktop_files

| particular attention to validating correct usage of Name, GenericName,
| Categories , StartupNotify entries.

Explanation for the StartupNotify entry usage in the desktop-entry-spec 
[1] that is linked in the guidelines. Also, there are important details 
in the Startup Notification Protocol Specification [2].

[1] 
http://standards.freedesktop.org/desktop-entry-spec/desktop-entry-spec-la...
[2] 
http://standards.freedesktop.org/startup-notification-spec/startup-notifi...

FYI When the StartupNotify=true was specified in the desktop file of the 
NetBeans I've seen bugs in launching of the NetBeans' child processes 
(e.g FireFox [3]) due to the DESKTOP_STARTUP_ID environment variable. It 
was fixed in the NetBeans launcher by a patch [4] according to 
recommendations of the Startup Notification Protocol Specification.

Swing needs to clear the environment variable.  See:

If an app uses GTK+ or Qt, does that alone always imply that it satisfies the 
desktop entry spec's requirements for StartupNotify=true, i.e. no further 
examination of the app's behavior is necessary?

http://standards.freedesktop.org/desktop-entry-spec/latest/ar01s05.html

"If true, it is KNOWN that the application will send a "remove" message
when 
started with the DESKTOP_STARTUP_ID environment variable set."

The main tricky situation comes when the app implements
single-instance behavior internally, and does some sort of IPC (dbus,
whatever) to talk to an existing instance.  In GNOME 3 this doesn't
matter as much because we do single-instance by default, but otherwise
it's definitely possible to get the stale "Starting foo..." until it
times out.   Actually handling this correctly is tricky[1], and I just
noticed one of my apps doesn't.  Maybe I should really take the plunge
and backport app tracking to GNOME 2 which would obviate this.

But as a general rule: add it.  Even for the IPC case, it only occurs
if the user tries to relaunch an existing app, which (albeit without
data, but with some educated background) is unusual.  Without IPC,
having it has a 99.9% chance of being correct.

[1] libunique handles this, but see also my fix for my app here:
http://git.gnome.org/browse/hotssh/commit/?id=57c43b39413c5128983286f5c09...

We have plans to basically make all this work out of the box when
using GTK+ but it blocks on gdbus.

[Chen Lei]

Should we also add  StartupWMClass=someting if StartupNotify=true doesn't work?

You're going to need to elaborate on "doesn't work".

* You don't see a "Starting..." notification in the tasklist in GNOME 2?
* You do, but it times out instead of disappearing when the app window comes up?
* Something else?

Well, for Firefox at least, it's option 2 and has been for a while (at
least under KDE):

I guess I should take some time to fix the most important app, yes.
This turned out to be a Fedora bug; we had a BuildRequires on
libstartup-notification, but didn't enable it in our mozconfig.  The
attached patch works for me, I'll add it to the bug too.

[Chen Lei]

Could you help me to fix qtiplot? After I add StartupNotify=true to qtiplot.desktop, it
times out instead of disappearing when the app window comes up under gnome2.

Chen Lei

Single-instance apps should really use something like libunique or KDE's 
KUniqueApplication instead of reinventing the wheel.
