--- Comment #13 from David Hurka <david.hu...@mailbox.org> ---
Please look at the following. It seems like keeping the file was implemented in
2008, specifically with Firefox in mind. But it broke something else, so it was
disabled using an #undef. There is no way anymore to enable it with a compile
switch or through an environment variable. It was also only implemented for
UNIX OSes.
@Pino: Can you tell more about the problem? Can it be fixed, or do we need
another approach than creating a file handle?
If we need another approach, I vote for creating a temporary full copy of the
file, if
a) the file is smaller than a limit, set by the memory performance mode
b) (optionally) the file is from a remote location or has a path that is likely
to be temporary (e. g. /tmp/, or **/.*/)

Keep an open file handle on the local file currently open: this way, we can
get it back from it,
in case for some reason (read: Firefox blindly removing temporary files) it
gets "deleted".
Of course, this works (and thus it is activated) only on UNIX systems (as
the file is not deleted for real until there are open handles on it).
BUG: 163363
(If not wanted, this behavior can be disabled by export'ing
OKULAR_NO_KEEP_FILE_OPEN to 1.)
Also, in case the local file gets deleted but the real document is remote,
use its (remote) URL for the copy.
