fd leak prevents removable media from being ejected

[ptomato]

I opened a file residing on removable media, through the portal, in the org.mozilla.Thunderbird app. Even after closing the app I couldn't eject the drive because it was "busy".

relevant entry from lsof (repeated many times):

xdg-docum  7925 14911 pool-/usr  ptomato   17u      REG                8,2 (file size redacted)       2282 /run/media/ptomato/(filename redacted)

Process 7925 is:

   7925 ?        Ssl    0:23 /usr/libexec/xdg-document-portal

Very similar to #509. It seems like somehow nobody cared about closing fds returned by g_unix_fd_list_append()

I will take a look at this soon

#530 might be the fix (on top of the other fixes in #515).

@ptomato can you reproduce this now?

[ptomato]

I don't know if I recreated the exact circumstances, but this does not seem to be a problem any longer in xdg-desktop-portal 1.16.0.

Thanks. Let's assume it was fixed then, but if you spot it again, please reopen

I thought this was #689

Looks a lot like it.
