I'm having troubles by accessing images that are created in my addon_data folder. 
For some reasons Kodi won't display them until a reboot of Kodi. They aren't cached too and not listed in the thumbnails folder or in the textures.db

Is the addon_data folder somehow cached? 
For testings I simply copied a dummy test.jpg to that folder and it's also not possible to show it in Kodi.

-> "<texture>E:\Kodi\Kodi Leia\portable_data\userdata\addon_data\script.embuary.helper\img\test.jpg</texture>" -> won't be displayed without a reboot of Kodi
-> "<texture>E:\test.jpg</texture>" -> works

Any way to work around this behaviour?

Code:

python:


def genre_thumb(genre,images):

    filename = genre + '_' + md5hash(images) + '.jpg'

    genre_thumb = os.path.join(ADDON_DATA_IMG_PATH, filename)



    if xbmcvfs.exists(genre_thumb):

        touch_file(genre_thumb)



    else:

        width, height = 356, 533

        cols, rows = 2, 2

        thumbnail_width = int(width / cols)

        thumbnail_height = int(height / rows)

        size = thumbnail_width, thumbnail_height



        ''' copy source posters to addon_data/img/tmp

        '''

        posters = list()

        for poster in images:

            posterfile = images.get(poster)

            temp_filename = genre + '_' + md5hash(posterfile) + '.jpg'

            image = _copyimg(posterfile,ADDON_DATA_IMG_TEMP_PATH,temp_filename)



            if image:

                posters.append(image)



        if not posters:

            return ''



        ''' create collage with copied posteres

        '''

        collage = Image.new('RGB', (width, height), (19,19,19))

        collage_images = []

        for poster in posters:

            try:

                image = ImageOps.fit(poster, (size), method=Image.ANTIALIAS, bleed=0.0, centering=(0.5, 0.5))

                collage_images.append(image)

            except Exception:

                pass



        i, x, y = 0, 0 ,0

        for row in range(rows):

            for col in range(cols):

                try:

                    collage.paste(collage_images,(int(x), int(y)))

                except Exception:

                    pass

                i += 1

                x += thumbnail_width

            y += thumbnail_height

            x = 0



        collage.save(genre_thumb,optimize=True,quality=85)



        ''' delete temporary copied files

        '''

        _deltemp()



    return genre_thumb

Created images in the folder:

Have you tried using "special://" paths instead of local?

Yep, tried all scenarios. Even image:// with encoded path.

I also have a background service running that is also creating an image (background blurred), that works well. And I've noticed that the issues does not appear if I disable the background blurring. What the f...

Odd, what about

xml:
<texture background="true">

No difference.

As I said, if I simply copy a dummy image to the addon data folder it's also not visible in Kodi without a restart.

I found the issue.
In my service I have a one time task when the service starts:

python:


    def __init__(self):

        addon_data_cleanup()

        service_start()

        .....



   def addon_data_cleanup(self,number_of_days=60):

        time_in_secs = time.time() - (number_of_days * 24 * 60 * 60)

        dirs, files = xbmcvfs.listdir(ADDON_DATA_IMG_PATH)



        for file in files:

            full_path = os.path.join(ADDON_DATA_IMG_PATH, file)

            stat = xbmcvfs.Stat(full_path)



            if stat.st_mtime() <= time_in_secs:

                xbmcvfs.delete(full_path)

For some reasons this function is "blocking" the folder. Can you tell me why?

Solved it by using 'os' instead of xbmcvfs. Totally weird, but OK. But it would be interesting to know why xbmcvfs was causing troubles in this scenario.

python:




        for file in os.listdir(ADDON_DATA_IMG_PATH):

            full_path = os.path.join(ADDON_DATA_IMG_PATH, file)

            if os.path.isfile(full_path):

                stat = os.stat(full_path)

                if stat.st_mtime <= time_in_secs:

                    os.remove(full_path)
