Description
Hi,
I have this erros during short time setting style o a spatialite layer. I don't know if this happend with other kind of vector layers.
I try to save QGIS or SLD style and I obtain thi error.
terminal says:
(qgis:2915): Gtk-WARNING **: Failed to read filechooser settings from "/home/ginetto/.config/gtk-2.0/gtkfilechooser.ini": Too many open files
It's hard to me to identify a procedure to reproduce the error.
This happend also with a single layer with single polygon project.
Context is:
QGIS version 2.1.0-Master QGIS code revision 4fd011f

Can you run the following command when this happens next time, replacing [qgis-pid] with the actual pid
ls -l /proc/[qgis-pid]/fd/

hmmm... seems is related to my opened db by my new plugin
it's full of: /tmp/srs.db
generating 20 more every zoom!
so probably it's my fault... one more check and after I'll close this ticket

no... it's not my fault!
on fly repropjection open 12 /tmp/srs.db EVERY zoom or canvas redraw!
I don't know if it's related with dataProvider type (spatialite)
it's possibile to generate e lot of /tmp/srs.db doing this steps:
0) open qgis
0.1) ls -l /proc/<qgis pid>/fd/ |wc = 18 (more or less constant during normal operation)
1) create a spatialite layer in a proyection (I've a multipolygon in srid 32632)
2) set project on fly projection with other srid (I've current srid to 3003)
3) load spatialite layer
4) ls -l /proc/<qgis pid>/fd/ |wc = X
5) zoom
6) ls -l /proc/<qgis pid>/fd/ |wc = X+12
probably we have to change the issue title to somthing like: "On the fly reprojection doesn't close related files /tmp/srs.db"
I leave this issue opened

- Affected QGIS version changed from 2.0.1 to master
- Target version changed from Version 2.0.0 to Future Release - High Priority
- Priority changed from Normal to Severe/Regression
- Category changed from 83 to Projection Support
I cannot add any technical detail but I can certainly confirm this issue as I have seen it many times in the last days on qgis master.

There was a missing delete / db close. However, it does not explain why the number of open db grows with every zoom.
Could you git pull and see if the issue is still there?

it works :)
19 opened at the open of qgis
37 after opened my project... after a while down to 25
zoom... remain 25 and after a while down to 23!
gooooood :)

Thank you for the quick fix Marco.
It seems this can be closed.
Out of curiosity, is there a reason to have it open more than once?
