this is evas's cache holding onto file handles even when not referenced. evas
has a cache that has 2 parts. active (referenced) files - this is a hash where
to avoid re-loading the same file we just look it up in our in-memory hash and
reference the existing copy. for images that go to a reference count of 0 - not
needed anymore, they go into a LRU (least recently used) list. this keeps a
limited AMOUNT of data (in MB - where this is not the file size byt the memory
size when decoded into pixels). the least recently used items are released once
we exceed our cache size limits. this has always been there in evas to avoid
re-loading data from disk all the time when we need it again soon after not
needing it anymore. this is one of those black-magic bits of efl and e that
actually make it perform very well.

the problem is - it's holding onto the files e displayed in its preview popup
in the cache. yes - there are api's to flush the cache/set its size etc. there
is config in e under "advanced" that lets you set cache sizes and a cache flush
interval (e will expunge all 0 ref count items every N ticks. 1 tick = 1/8th of
a second). so lower flush interval ad the problem will go away for now. or well
drop it to 8 ticks and after 1 second your unmounting will work happily. :)

[e-users] umount external sub does not work because enlightenment process keeps file open

2015-09-19 Thread Peter Koellner 
Hi!

I just had the effect that I can't unmount an external USB drive after opening 
one of the files in there from the file manager window, neither from shell nor 
from the desktop disc icon menu.

peter@kropotkin:~$ umount /media/peter/TOSHIBA\ EXT
Error unmounting block device 8:17: 
GDBus.Error:org.freedesktop.UDisks2.Error.DeviceBusy: Error unmounting 
/dev/sdb1: Command-line `umount  "/media/peter/TOSHIBA EXT"' exited with 
non-zero exit status 32: umount: /media/peter/TOSHIBA EXT: target is busy
 (In some cases useful info about processes that
  use the device is found by lsof(8) or fuser(1).)


I have closed the atril viewer, but lsof +D /media/.../topdir says that the 
enlightenment process still has the file open:

peter@kropotkin:~$ lsof +D /media/peter/TOSHIBA\ EXT/
COMMANDPID  USER   FD   TYPE DEVICE SIZE/OFF   NODE NAME
enlighten 3800 peter  127r   REG   8,17 7918 101096 /media/peter/TOSHIBA 
EXT/Empresa/2015/q3/Gastos/aaa/x/yy.pdf

The effect is reproducible by clicking on the desktop disc icon and 
double-clicking on some PDF document. The atril viewer pops up. After closing 
the viewer I get the following result:

peter@kropotkin:~$ lsof +D /media/peter/TOSHIBA\ EXT/
COMMANDPID  USER   FD   TYPE DEVICE SIZE/OFF   NODE NAME
enlighten 3800 peter   75r   REG   8,17  1772495 35 /media/peter/TOSHIBA 
EXT/doc/TOSHIBA CANVIO BASICS.PDF
enlighten 3800 peter  127r   REG   8,17 7918 101096 /media/peter/TOSHIBA 
EXT/Empresa/2015/q3/Gastos/aaa/x/yy.pdf


atril is no longer running at this point.

I have efl and elementary 1.15.1 and enlightenment 0.19.9 installed...

Any ideas?

I posted about the same problem a month or two ago, but with efl, elementary 
on  1.15.0 and enlightenment on 0.19.8.

If I hover over certain files, e.g. pdf, I can no longer unmount the USB 
drive.  enlightenment seems to be holding onto it for some reason, well after 
the hover over preview has stopped.

I am guessing it is a bug.
