Problem with Digikam on MacOSX - Too many open files...

[Gerard Milhaud]

Hi,

When I connect my collection (~10K images) to my fresh 2.6 install on
MacOsX Lion, I've a crash "Too many open files"...
When googling I see an old QT bug related to this problem for the Mac
environment :
http://sourceforge.net/projects/wally/forums/forum/848087/topic/3496445

Exemple of error log :
> QKqueueFileSystemWatcherEngine::addPaths: open: Too many open files
> QFileSystemWatcher: failed to add paths:
> /Users/g/PHOTO/PhotosG/Albums/2004-01-28_Salle-Machines-CharlieHebdo

I've also these errors :

> digikam(26532)/KSharedDataCache: Unable to setup shared cache lock,
> although it worked when created.
> digikam(26532)/KSharedDataCache: Unable to unmap shared memory segment
> 0x10d31f000
>
> QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is
> still in use, all queries will cease to work.

to the end... :

> open files
> QEventDispatcherUNIXPrivate(): Can not continue without a thread pipe
> QKqueueFileSystemWatcherEngine: error during kevent wait: Bad file

> KCrash: Application 'digikam' crashing...

The full crash trace is attached...

Any idea ??

Thanks in advance,

G.

OK.

To "survive" until the bug was solved, do you think a workaround in Digikam code like if OS==MacOS then disable "open file checking"  would be possible ? Or it is a too big modif ?

Not a big problem for me, I'm waiting with my VM Kubuntu + Digikam 2.5 hosted on my Mac... But I was so glad to finally build 2.6 on Lion and lauch it, what a deception when digikam finally crashes when I connect my collection... after so many efforts...

Thank you,

G.

See comment 7 on the above bug report that Gilles sent you. The patch in the
comment does exactly that, it's pretty simple. If you have digikam's git repo
cloned, then simply. Download the patch
 $ cd digikam-sc/core
 $ git am 0001-disable-filewatching-on-OS-X-but-dir-watching-still-.patch


If you're just using the source tar file, then you might have to do
 $ cd digikam/core
 $ patch -p1 < 0001-disable-filewatching-on-OS-X-but-dir-watching-still-.patch

now compile.

Caution: i don't have my mac in front of me, these commands above may not be
exact.

YYYYYYYYYYYYYYYYYYYYYEEEEEEEEEEEEEEEEEEEEEEEEEEEEESSSSSSSSSSSSSSSSSSSSSSS !!!!!!!!!!!!!!!!!!

It finally works ! Your 5 lines patch has the extraordinary power to
make digikam 2.6 on MacOSLion at last OK, with my 11 years of
photography correctly handled, the thousands of tags (from numerous old
install of Digikam (FreeBSD, Linux, Windows) since 6 years) up and
running and my digikam4.db of >40Mb recognized...

The end of a long long effort...

Thank you, thank all the digikam people... Version 2.6 is great.

@Brad : Curiosity : Do you know whait is exactly the impact of disabling
file-watching for digikam on MacOS ?
