Xfce 4.8 on BSD flavors

  • January 19, 2011
  • Jannis Pohlmann

I should’ve made this more clear in the Xfce 4.8 release announcement but for a moment there I forgot that not everyone knows what we developers are dealing with under the hood.

Many users have been asking what the BSD problems are that I mentioned in the announcement. As some of you may recall is that HAL, the hardware abstraction layer that has for the past few years been used for volume and power management as well as a few other things, has been deprecated and replaced by a variety of frameworks. Today there is udev for device information, udisks for volume management, upower for power management as well as ConsoleKit and PolicyKit for session and permission control.

At least udev is strongly linked to Linux and as far as I know is not available on any of the BSD flavors. Unfortunately it is now the only good way to detect storage devices, cameras, printers, scanners and other devices using a single framework. That’s why we use it in Xfce now in situations where HAL provided us with device capabilities and information to distinguish between the different device types before. The consequence is that thunar-volman no longer works without udev and thus only compiles on Linux. In Thunar itself udev remains optional.

I don’t know what the porting status of the other frameworks is. But I am pretty sure not all of them have been ported to other platforms yet which is why I felt the need to express our disappointment in the announcement. For 2-3 years now all this has been a big mess. New frameworks were invented, dropped again, renamed from *Kit to u* and somewhere on the way it became impossible to keep Xfce as portable as it was before. I know that this is nothing new and that BSD folks faced the same situation as they do now back when HAL was invented but I don’t think it has to be this way.

For the question how we can improve the situation I have no answer yet.

Xfce 4.8 released!

  • January 16, 2011
  • Jannis Pohlmann

Today, after almost two years of work, we have the special pleasure of announcing the much awaited release of Xfce 4.8, the new stable version that supersedes Xfce 4.6.

We hope that everyone will enjoy this release as much as we do. Sadly, this will not be the case as the folks using any of the BSD systems will notice a sudden loss of features. We think that this announcement is a good opportunity to express our disagreement with the recent “Linux-only” developments in the open source ecosystem, especially with regards to the utilities we need in desktop environments.

Xfce 4.8 is our attempt to update the Xfce code base to all the new desktop frameworks that were introduced in the past few years. We hope that our efforts to drop pieces like ThunarVFS and HAL with GIO, udev, ConsoleKit and PolicyKit will help bringing the Xfce desktop to modern distributions.

With Xfce 4.8 our users will be able to browse remote shares using a variety of protocols (SFTP, SMB, FTP and many more). The window clutter has been reduced by merging all file progress dialogs into a single one.

Our panel application has been rewritten, thereby improvingpositioning, transparency, item and launcher management. It also introduces a new menu plugin to view directories. Its plugin framework remains compatible with 4.6 plugins.

We also improved our settings dialogs. The display configuration dialog now supports RandR 1.2, detects screens automatically and allows our users to pick their favorite resolution, refresh rate, rotation. Screens can be configured to either work in clone mode or be placed next to each other. Keyboard selection has become easier and more user-friendly. Also, the manual settings editor has been updated be more functional.

Aside from the features implemented in Xfce, the 4.8 development cycle brought us a bunch of other goodies. For the first time we had a serious release strategy formed after the “Xfce Release and Development Model” developed at the Ubuntu Desktop Summit in May 2009. A new web application made release management a lot easier. We worked hard on improving the situation of Xfce translators which led us to setting up our own Transifex server. Something else you will hopefully notice is that our server and mirroring infrastructure has been improved so that our servers hopefully will not suddenly surrender shortly after this release announcement.

There is a lot more to discover and we hope a lot of you will give Xfce 4.8 a try! There is a brief tour online on

http://xfce.org/ and http://xfce.org/about/tour

A summary of the changes since the 4.8pre3 preview release is available on the following URL (it also includes links to the changes introduced in all preview releases):

The release can be downloaded either as individual releases or as a fat tarball including all these individual versions:

2011 has just begun and we are already planning for the future. The 4.10 schedule will be worked on soon and hopefully, we will be able to turn Xfce into a non-profit organization at this year’s FOSDEM, so stay tuned!

But until then we hope you will enjoy today’s release and join us in celebrating. Thanks go out to all our contributors, bug reporters as well as the awesome efforts of our translators and packagers.

Best regards,
The Xfce development team

Attending FOSDEM 2011

  • January 10, 2011
  • Jannis Pohlmann

I'm going to FOSDEM, the Free and Open
Source Software Developers' European Meeting

Today Nick and I booked hotel rooms for FOSDEM so now it’s official that the two of us will be there. I’m very much looking forward to it and I’m hoping to meet some of you at the FOSDEM Beer Event on Friday! Still need to think about a way to make ourselves recognizable as Xfce folks though.

If you are planning to attend and would like to meet any of the Xfce folks, please add your name in the wiki:

  http://wiki.xfce.org/events/2011/fosdem

We haven’t decided where and when to meet on Saturday and Sunday but I’m sure we will find something. Stay tuned for additional announcements on this weblog.

In addition to celebrating the 4.8 release of Xfce which is scheduled for next weekend, one of our goals for FOSDEM 2011 will be to sign the papers for registering the Xfce Foundation e.V. in Germany. The details of this still need to be worked out, however. I’ll keep you posted about this as well.

If you would like to talk to me about things other than Xfce, please drop me a mail and I’m sure we can arrange something.

Today we are pleased to announce the third and hopefully final preview release of Xfce 4.8 which is set to be pushed out to the public on January 16th, 2011. Compared to Xfce 4.8pre2 this release mostly features translation updates and bug fixes.

With christmas and new year’s eve between 4.8pre2 and 4.8pre3 it comes as no surprise that for most components only a few issues were tackled.

Among other things we updated the default keyboard shortcuts to include monitor keys. The status icon of the file manager’s progress dialog is now properly hidden when the dialog is destroyed. It’s wallpaper plugin is now capable of handling filenames with spaces. The environment variables of commands launched from the Xfce run dialog were not set properly, so we fixed that so that commands launched from the dialog always inherit the environment of the Xfce session.

We also made the --reboot and --halt parameters of xfce4-session-logout work again which previously simply logged out the active user. In order to avoid a race condition at session startup and in order to speed things up a little more we no longer use xrdb to update xft and cursor settings and instead, update the related XSETTINGS properties ourselves.

In the window manager xfwm4, we aligned the time period required for a double click with that of normal applications. Via the hidden option “/general/mousewheel_rollup” one can now disable windows being rolled up via the mouse wheel. The window manager now also properly handles resolution changes in fullscreen windows like those appearing in games. Xfwm4’s application switcher now only appears once in cloned mode.

This may sound like a few useful fixes but it’s nothing compared to the amount of work that went into the new Xfce panel once again. Around 20+ known bugs and regressions were fixed. Here is a short excerpt of the complete changelog: Translation domains were fixed for external plugins, plugins can be reordered with DND again, double-clicking items in the item editor shows their preferences, dragging items to the item editor dialog removes them from the panel again, tasklist windows can now be filtered by monitor. Another issue that appeared recently and has now been fixed is the icon sizing in the notification area, also known as the systray.

Xfce 4.8pre3 also features a lot of translation updates, as can be seen in the complete changelog on

 http://xfce.org/documentation/changelogs/4.8pre3

Since we’re following the Xfce release model for 4.8, we’d normally announce code freeze and the creation of early lifecycle support branches today. We decided against this because there are not enough people active to take care of all this at the moment. So we will continue fixing bugs in master branches as we did between 4.8pre2 and 4.8pre3.

We’re hoping that you will enjoy today’s release. Thanks a lot to everyone contributing this time around! We’re pretty sure 4.8 is gonna rock.

Kind regards,

The Xfce development team

P.S.: Happy new year everyone!

Release notes for 4.8pre2

We are pleased to announce the second preview release of Xfce 4.8. This release marks the beginning of the string freeze. From today on until the final release, strings may no longer be changed in the master branch of Xfce core components. This will help translators to prepare their translations for the final release scheduled on January 16th, 2011.

For this release we focused on fixing bugs in all Xfce components. We managed to close a great number of them thanks to all the persons who reported them and tested proposed fixes quickly.

A few minor panel features were added despite feature freeze. We also managed to work on two long time requests: proper support for editing the application menu with menu editors (Alacarte being the one that we tested) and integration with the Compiz viewport. Of course, this release also features a lot of new and improved translations thanks to the amazing work of our translation teams.

A list of all changes is available on:

http://mocha.xfce.org/documentation/changelogs/4.8pre2

We hope you will enjoy this release. Please give us feedback by sharing your thoughts, blogging, tweeting, denting or by filing bug reports. With your help, 4.8 will be the best release ever (at least until 4.10)!

Kind regards and thanks to everyone who has contributed to this release,

Release notes for 4.8pre1

The Xfce development team is proud to announce the first preview release for Xfce 4.8. Together with this preview release, the Xfce project announces the feature freeze for the final 4.8 release which is set to be pushed out to the world on January 16th, 2011.

This release incorporates major changes to the core of the Xfce desktop environment and hopefully succeeds in fulfilling a number of long time requests. Among the most notable updates is that we have ported the entire Xfce core (Thunar, xfdesktop and thunar-volman in particular) from ThunarVFS to GIO, bringing remote filesystems to the Xfce desktop. The panel has been rewritten from scratch and provides better launcher management and improved multi-head support. The list of new panel features is too long to mention in its entirety here. Thanks to the new menu library garcon (formerly known as libxfce4menu, but rewritten once again) we now support menu editing via a third-party menu editor such as Alacarte (we do not ship our own yet). Our core libraries have been streamlined a bit, a good examplle being the newly introduced libxfce4ui library which is meant to replace libxfcegui4.

Perhaps the most important achievement we will accomplish with Xfce 4.8 is that, despite suffering from the small size of the development team from time to time, the core of the desktop environment has been aligned with today’s desktop technologies such as GIO, ConsoleKit, PolicyKit, udev and many more. A lot of old cruft like has been stripped from the core as well, as has happened with HAL and ThunarVFS (which is still around for compatibility reasons).

Thanks to the awesome Transifex translation platform, our language teams have been able to update their translations at an incredible pace. Please include them when praising this release!

A complete list of all changes since the latest stable release is available on

Below you will find download information for Xfce4.8pre1. Please give our mirrors a few hours to synchronize. We hope you will enjoy this release, feel encouraged to blog and tweet about it! Feedback is welcome in all forms. Bugs can be reported in our bug tracker as usual. We need your help to make Xfce 4.8 our best release ever!

Kind regards and thanks to everyone who has contributed to this release,

Final exams, diplom thesis and thunar-volman

  • July 17, 2010
  • Jannis Pohlmann

I guess it’s time for an update.

This week I passed the last of four final exams in computer science and human-computer interaction at my university. Not only am I pleased that nine months of learning are over; I am also blessed with excellent grades. And while my understand of good grades is similar to that of money (nice to have it but nothing to focus on and/or brag with), I have to admit that this time I’m at least a little proud of myself. Five years at the university are slowly coming to an end, the first friends are leaving town and it will soon be time to take the next big step in life.

I cannot leave this city before writing another thesis, however. Thus, I am currently looking for a Diplom thesis at the university or at companies related to open source technologies. If you happen work for such a company with interesting thesis ideas or opportunities, please let me know. The thesis is supposed to take about 6 months, ideally starting early in September. After that it’s time to pack my stuff and look for an employer. I’m hoping for a position in open source software development. Areas I’m particularly interested in include Linux, mobile computing, desktop-related technologies as well as renewable energy, environment protection and open government. I’m here to make a difference.

On to something else. A few weeks ago I was offered sponsoring in order to work on thunar-volman for a few days. I accepted the offer, so for the entire next week from 2010-07-19 to 2010-07-26 (including the weekend) I’ll do some sponsored work on porting Thunar and thunar-volman to udev and GIO! The goal is to finish all major features (storage devices, cameras etc.).

Yesterday I did some warm-up hacking on tumbler to verify that if I’m still up to the task. The results: a new ffmpegthumbnailer-based video thumbnailer plugin (written by Lionel Le Folgoc), a new PDF/PostScript thumbnailer plugin based on poppler-glib and a new tumbler release (0.1.2). The master branch contains another commit adding arbitrary URI support to the PDF/PostScript thumbnailer but for that you’ll have to wait until the next release.

That’s it for now, I’ll be a lot more active next week. Take care everyone!

Xfce 4.8 Schedule Changes

  • January 26, 2010
  • Jannis Pohlmann

As the Xfce release manager, I’d prefer to be the bringer of good news. Unfortunately, we have to make some adjustments with regards to the Xfce 4.8 release schedule.

You may well remember last year’s chaos with the 4.6 release date. We’re trying our best not to repeat that and if it should happen again, we’ll at least keep you posted about the issues as good as we can.

So, what’s the deal with 4.8?

One thing that hasn’t changed much is that our development team is very small. A hobby project of this size requires a certain amount of time to be invested by each individual developer. Time not everyone has as much has he would like to dedicate to Xfce.

Today, Brian announced his absence for the coming months due to his new job, leaving 2-3 of our core components (xfdesktop, xfconf and xfce4-session) more or less unmaintained (aside from bugfixes). The good news is that Jérôme (who has recently started to improve xfce4-settings and port xfce4-session to libxfce4ui) and Daniel (the maintainer of the thunar-shares-plugin) have offered their help with xfdesktop and xfce4-session.

Brian is not the only one having little time at hand though. I’m preparing myself for my final university exams, so ideally I’d be sticking my nose into lecture notes all day long. I still have the time to write mails like this but there hasn’t been much activity around thunar and related projects lately.

Again, I’m really happy to see people volunteering to help because that’s what we need right now. There’s a lot left to do before we can release 4.8. Let me get to that now.

As some of might have heard, thunar was ported to GIO this summer. Through GVfs, GIO brings new features such as SMB, SFTP, FTP browsing which some people use one a daily basis already. Now, GVfs has turned out to be problematic for us for various reasons. At first it shipped a HAL-based volume monitor with a hard-coded dependency on gnome-mount. Today it ships a volume monitor based on gnome-disk-utility (uses DeviceKit-disks itself) which proves to be inconsistent and somewhat incompatible to the HAL mounting code in exo.

The result: thunar-volman (not part of the core but important for thunar nonetheless) and xfdesktop will have to be ported to udev (the mounting being done with GIO, ideally). I’ve started working on this but this is far from being finished.

Question to the other developers: Didn’t xfce4-session use HAL for logging out and stuff? We might have to look into replacing those portions of code with something based on ConsoleKit, I guess?

HAL/udev is not the only issue however. With Xfce 4.8 we’ll be replacing libxfcegui4 with a new library called libxfce4ui. Not all core applications (again, xfdesktop being one of them, I think) have been ported to it yet. In most cases, this is no big deal and probably could be resolved within a few days though.

Then we have garcon, the much improved menu library that is supposed to replace libxfce4menu. At the time of writing the only feature it is lacking that is crucial for 4.8 is file system monitoring. We’ll probably implement basic monitoring like we had in libxfce4menu. Work on this hasn’t started yet.

Also, xfdesktop needs to be ported not only from ThunarVFS/HAL to GIO/udev but also from libxfce4menu to garcon.

So, as you can see there is quite a lot of work ahead of us. Taking into account the little free time some of us have these days, we’ve decided to postpone the 4.8 release until June 12th instead of April 12th. The entire release phase in our schedule has been moved by two months in time, as you can see on the official schedule wiki page:

 http://wiki.xfce.org/releng/4.8/schedule

To be honest, I wouldn’t consider this new date fixed either. It all depends on how much we can do until the feature freeze on April 1st. I’m optimistic that meeting the deadlines is possible though.

For all of you who can’t wait until June, try out our development releases which are announced on http://identi.ca/xfce. I have at least something good to share: For a few weeks now I’ve been running Fedora 12 with a mixture of Xfce 4.6 packages and development package from the upcoming 4.8 series and the new components have proven to be very stable already.

I’m especially happy about the new panel which works almost flawlessly (except for a few dual head issues) and not only supports real transparency and more comfortable launcher creation based on garcon, but is also compatible to panel plugins written for Xfce 4.6. (Good work, Nick!)

So, I guess this is it. A mixture of good and bad. I hope nobody is too disappointed. As always, we’re doing the best we can.

Cheers!

Thunar-volman and the deprecation of HAL in Xfce

  • January 16, 2010
  • Jannis Pohlmann

Last week I started looking at thunar-volman (a program that performs certain actions when new devices are plugged in) with the goal to make it compatible with the latest release of thunar which uses GIO instead of ThunarVFS for almost everything that takes place under the hood.

Until now, volume management (monitoring and mounting) in Xfce was done through HAL, the hardware abstraction layer that is currently being deprecated and dropped by major distributions. The functionality previously provided by HAL has been moved into udev, udisks (formerly known as DeviceKit-disks) and upower (formerly known as DeviceKit-power).

Volume management is transparently supported by GIO, meaning that applications don’t have to worry about the backend implementation. It should, in theory, not matter whether HAL is used or udev/udisks. Unsurprisingly, in reality, things are not that trivial, mainly for two reasons:

  1. Due to its focus on file management, GIO only supports monitoring and detecting storage devices (DVD drives, USB sticks etc.). There is no way to be notified when e.g. a digital camera or a portable media player is plugged in. This is critical for the functionality of thunar-volman which until now supported everything from cameras, media players, blank CDs/DVDs, audio CDs, PDAs and printers to input devices like keyboards, mice and tablets.
  2. Mounting volumes with udisks seems to be somewhat incompatible with HAL. I tried to mount volumes with thunar-volman and exo-mount (both implemented on top of HAL) and was for the root password upon unmounting in Thunar (using GIO and gnome-disk-utility/DeviceKit-disks). It seems like volumes mounted with HAL are assumed to be mounted by a different than the current user and thus, require root privileges to be unmounted.

HAL being deprecated and somewhat incompatible with udisks, what are the consequences for Xfce, and for thunar and thunar-volman in particular?

Let us, for a moment, assume Xfce 4.8 and thunar 1.0 were released as they are today, with thunar using GIO (and udisks instead of HAL in all major Linux distributions) and the rest (like thunar-volman and exo-mount) depending on HAL. As mentioned before, exo-mount and thunar wouldn’t work together in multi-user setups. Thunar would no longer detect cameras, PDAs, audio CDs, blank disks, mice, keyboards, tablets, media players and thunar-volman would end up being completely useless, as it is not detecting devices by itself. I think it is safe to say that this is not what we want.

In the following, I will focus on how to deal with thunar-volman. The rest of Xfce faces a similar roadmap, however. With regards to thunar-volman, there are (at least) three sane options:

  1. Drop thunar-volman and only support auto-mounting storage devices from now on, directly implemented in thunar. What is very obvious about this solution is that a lot of possibly useful functionality is lost.
  2. Port thunar-volman to (g)udev/udisks/GIO and make it a standalone daemon so that thunar no longer has to spawn it when new devices are plugged in. The advantage of this approach is that thunar only needs to depend on GIO and doesn’t have to implement the device detection part.
  3. Port thunar-volman to (g)udev/udisks/GIO as described above and make thunar depend on (g)udev for device detection. Spawn thunar-volman when devices are added/removed. The advantage over the previous approach is that thunar-volman doesn’t have to run permanently as a daemon. The additional thunar dependency on (g)udev could be seen as a disadvantage but on the other hand, it basically replaces another (HAL).

Now, everyone knows that programmers are lazy people. So, in the hope of being able to save some work, I started a survey on the usage of thunar-volman. The idea was to find out which of its features are used most and whether there are some that nobody really cares about. Here are the results:

=======================================================================================
                                                        Feature   #Users   Percentage

                Thunar Volume Manager Usage Survey with 93 participants

According to the results of this survey, auto-mounting and browsing of removable drives and media have highest priority among the 93 participating thunar-volman users. This more or less covers the functionality we could cover with GIO alone (plus automatically running a program when new drives and media are inserted). However, a third of the users also use thunar-volman for importing photographs from digital cameras and for playing video and audio CDs as well as DVDs automatically. Almost a 25 percent of all users use thunar-volman to start their favorite burning software when a blank CD or DVD is inserted. Slightly more than 10 percent want thunar-volman to start playing music on portable media players when they are plugged in. Printers and Palms are also somewhat relevant.

This survey confirms my expectations that handling storage devices alone is not enough even though they clearly are the most important use case for thunar-volman. Our users seem to like the flexibility of thunar-volman and make use of it. This disqualifies option 1 and leaves us with options 2 and 3. I’m inclined to avoid another daemon and go for number 3.

In preparation for porting thunar and thunar-volman to udev/udisks/GIO, I’ve created a wiki page to collect information about how we can reliably distinguish the different device types based on udev properties: http://wiki.xfce.org/dev/thunar-volman-udev. If you have blue-ray disks, video CDs, a digital camera, a Pocket PC, a Palm, a USB printer or a graphics tablet, you could make me very happy if you inserted them or plugged them in and sent me the output of udevadm info --export-db to my Xfce email address together with a short hint what devices you’ve plugged in. Alternatively, you can paste/upload the output somewhere on the internet and comment on this blog post, and thereby help making future versions of Xfce better.

Cheers!

This is just a short heads up concerning Tumbler. I just merged Philip’s last critical commit to complete support for specialized thumbnailer services into master. We’ll have to give this some testing but I’m quite optimistic that we’ll be able to release 0.1.0 this weekend or next week. A new release of Thunar will follow shortly after that in preparation for 1.2 (to be released along with Xfce 4.8), supporting virtual and remote file systems based on GIO.

I’ve been pretty occupied lately. Aside from learning for my final university exams I finished my short thesis on porting Thunar to GIO. I already got the very positive results back and I’m going to publish the official version of the thesis soon. Unfortunately, being busy has started to cause not-so-positive developments as well. I haven’t had much time to hack on anything lately and my attendence of FOSDEM 2010 is uncertain. I might still go but I failed to organize anything related to Xfce this year, leaving us without a devroom and talks. So it’d be more like a private meetup rather than an organized team trip with the goal to represent Xfce.

Another consequence of me being busy is that Xfce 4.8 might include less features than planned, at least with regards to the ones I had in mind. For now let’s just hope that I’ll find a little more time for hacking the next months. It doesn’t look too well right now but who knows…
