How many recent files does an application really need?
A few days ago, Claudio wrote about the time Eog spent saving the filename of the recenly used image into ~/.recently-used.xbel. The reason: ~/.recently-used.xbel was too big. If I remember correctly, the FileChooser used to have a similar issue in the past.
Passing from 5.8 MiB to 1.8 MiB, through deleting all those items whose files does not exists, seems a bit gain. I wanted to go a bit further and I wondered ¿How many recent files does an application really need? (sorry, not that futher :-) I do not think more than 10, but let me know if I am wrong.
I wrote my own version of <a href=”http://www.gnome.org/~csaavedra/news-2008-03.html#D23″>Claudio’s program</a> with considering that matter. And my ~/.recently-used.xbel file went from 1.2 MiB to 54 KiB. Before to go to the script, let me show the numbers I got in a computer with less than two month of non intensive use:
gpoo@pendragon:~$ python clean-recently-used.py -v Summary: 1 Reproductor de películas Totem 1 Glade 4 GNU Image Manipulation Program 4 Navegador web 9 Visor de documentos Evince 9 File Roller 14 Web Browser 15 Gnumeric Spreadsheet 26 gedit 34 Administrador de archivos 36 Evince Document Viewer 52 Totem Movie Player 292 File Manager 1151 Eye of GNOME Image Viewer
When I load Eog, it only show me the last 5 files I opened before. Why does it need 1146 extra items stored?
Nevermind. The <a href=”http://www.gnome.org/~gpoo/bag/clean-recently-used.py”>script</a> I wrote is simple. It delete the files that does not exists (the same strategy as Claudio’s program), but it also delete the files that are not so recently used, and I got the following numbers:
gpoo@pendragon:~$ python clean-recently-used.py -v Summary: 1 Glade 3 GNU Image Manipulation Program 4 Navegador web 8 File Roller 9 Visor de documentos Evince 10 Totem Movie Player 10 Eye of GNOME Image Viewer 10 Web Browser 10 Gnumeric Spreadsheet 12 Evince Document Viewer 13 Administrador de archivos 14 gedit 41 File Manager
Now you can put the <a href=”http://www.gnome.org/~gpoo/bag/clean-recently-used.py”>script</a> to be executed when you start your session or you can program a cron task to do it.
You can play with the script using it just with -v, which will give you only a summary of use.
And it is slow when delete items (in seconds), but much better when it is controlled.
