Bug 469805

SUMMARY
***
In digiKam, when using the face recognition feature from within the Album view, it appears that subfolders contained in albums from external drives are not being scanned. The software only scans the main folder, omitting any images that might be present in the subfolders.

Additionally, when attempting to perform face recognition on large collections, if the process is interrupted and then restarted, it seems to start from the beginning each time. This makes scanning large collections impractical, especially if interruptions are necessary due to the size of the collection.
***


STEPS TO REPRODUCE
1.    Connect an external drive with an album that contains subfolders.
2.    Open digiKam and navigate to the People view.
3.    There is no subfolders for albums on external hard drives
4.    Notice that only the main folder of the album is scanned, and the subfolders are ignored.

Also if I scan for faces from within the Album-view, where the subfolders are actually shown the following happens
1. Connect an external drive with an album that contains subfolders.
2. Open digiKam and navigate to the Album view.
3. Initiate the face recognition process.
4. Subfolders are scanned.
5. Interrupt the face recognition process and close digiKam.
6. Reopen digiKam and resume the face recognition process.
7. Notice that the face-detection process restarts from the beginning, rather than picking up where it left off.


OBSERVED RESULT
1. There is no subfolders for albums on external hard drives in People view
2. When the face recognition process is initiated from the Album view, only the main folder of the album is scanned. Subfolders within the album are ignored.
3. If the face recognition process is interrupted and then restarted, it starts over from the beginning, rather than resuming from where it left off.


EXPECTED RESULT
1. When initiating the face recognition process from within people view, the software should scan not only the main album folders but also any subfolders, ensuring all images are processed.
2. The face recognition process should remember its progress between sessions or give an option in Album view, allowing for it to be paused and resumed without starting from the beginning each time.
