Hi,<br><br>I am porting a pygtk application to maemo. It works alright, but I noticed that it was consuming lot of memory, preventing me from opening other applications.<br><br>When I investigated, I found that my python application was forking 4 more instances of itself, each one identical in memory footprint. Thus they consumed nearly 60-70% of my memory.
<br><br>So I ran my application using pdb and narrowed down to a code segment that was leading to multiple instances of the process. It turned out that when I call run() on hildon.fileChooserDialog object, the dialog opens and at that moment in the "top" I see 4 more instances being forked.
<br><br>I fail to understand this behavior. I replaced the hildon widgets by pure gtk widgets and I see similar behavior, except that 2 more instances get forked. Also when using gtk.FileChooserDialog, these new instances get created in the instantiation of the dialog object, rather than call to run(). (code included below)
<br><br>So to further explore the problem, I ran same application on my desktop with gtk widgets. But I verified that when fileChooserDialog's run is called, there are no additional instances of python.<br><br>I am running this code on n770, with 2007 HE and
python2.5 runtime. My application code is pure python and not using any additional libraries. In fact following would be a simpler version of it to reproduce the problem:<br><br><blockquote>import gtk<br>import hildon<br>
<br>#window = gtk.Window(gtk.WINDOW_TOPLEVEL)<br><br>#fileChooser = gtk.FileChooserDialog(<br># title="Choose a photo to publish",<br># buttons=(gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL,<br># gtk.STOCK_OK
, gtk.RESPONSE_OK))<br><br>fileChooser = hildon.FileChooserDialog(<br> window,gtk.FILE_CHOOSER_ACTION_OPEN)<br><br><br>result = fileChooser.run()<br><br>if result == gtk.RESPONSE_OK:<br> print fileChooser.get_filename
()<br><br clear="all"></blockquote>Do you have any tips, as to what might be going wrong?<br><br>This problem is fatal at least on n770 - it will trigger low memory message when other applications are used on the side.<br>
<br>Any help will be useful.<br><br>Thanks,<br>-- <br>---<br>Jayesh
