[digikam] [Bug 335013] New: The face recognition and detection plugin does not respect the picked albums

[Roland Wolters]

https://bugs.kde.org/show_bug.cgi?id=335013

            Bug ID: 335013
           Summary: The face recognition and detection plugin does not
                    respect the picked albums
    Classification: Unclassified
           Product: digikam
           Version: 4.0.0
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Face Management
          Assignee: [hidden email]
          Reporter: [hidden email]

When I go to the tab for face recognition and detection and pick certain albums
to search, this is not respected. Instead, all available albums are searched,
continuing a search I launched much, much earlier and ended by closing digikam.

Reproducible: Always

Steps to Reproduce:
1. Got to the face detection
2. pick an album
3. launch the search
Actual Results:  
The picked albums are not searched, no new faces come up.

Expected Results:  
The picked albums - and only them - should be searched. With only few images,
that should be rather quick.

Not sure if a previous search which was cancelled by closing Digikam (because
there is no button to cancel searches) is mixing up the situation here.

yes it must be.

Look on bottom right corner of albugui. There is a progress indicator on
statusbar, where you can see details of scan cancel operation.

In the above uploaded pictures you can see the options I picked this time,
though here no ablums are selected.
Besides, the second screen shot was done directly after I started a
recognization of the entire collection - and no status bar is shown. In the
background several digikam processes are running, though...

Why do you turn on "Whole Albums Selection" and "Whole Tags selection" options
?

These options will ignore custom album/tag selections done through tre-view
combobox and process whole collection instead...

--- Comment #7 from Roland Wolters <[hidden email]> ---
I'm sorry, the screenshot was the wrong one. With the usual search I do not
turn on "Whole Album selection", but only pick two albums. I do however turn on
"Whole Tags Selection". Does this still trigger an entire collection scan?

I changed the search options to only search two albums together with two tags.
Upon start, the option window vanishes, and CPU and RAM for two digikam
processes spikes. Btw., again there is no status bar or anything but my process
viewer (and my laptop fan) indicating that there is any background process...
or am I just not seeing it?

Anyway, I tested two times, an each time - again, two albums and two tags
chosen, together roughly 150 photos, 600 MB of space - OOM-Killer ( ! ) killed
both processes... we speak about a system with 8G Ram and as much swap space.
But that might be another bug?

To respond on comment #7

I do however turn on "Whole Tags Selection". Does this still trigger an entire
collection scan?

==> I start a scan of all image tags with virtual albums selection. If tags is
used on many place, this will take a time to process...

I just checked album selector widget with some debug statement, and selection
of albums to process in background is repected.

The main problem is not album selector here, but memory consumption in
background...

Git commit 42ccb101aeb7c3ed79dd41d0d10a8f67a53883e2 by Gilles Caulier.
Committed on 14/09/2016 at 20:23.
Pushed by cgilles into branch 'master'.

make the album selection widget exclusive with album type : PAlbum or TAlbum
(not and operator).
This will prevent to scan a selection of PAlbum when TAlbum are selected.
Related: bug 334183, bug 366558
FIXED-IN: 5.2.0
