Daemonize -> no images

    I've just deployed a new web app developed with Xojo.
    It's hosted as a standalone app in a Ubuntu server with Nginx with SSL are using Posgresql as database server.
    When the app is launched manually without daemonization in a SSH session (./xxx), everything works well.
    If the app is launched daemonized, the app images are not displayed.
    I'm talking about images managed in Xojo (imported in the IDE) and linked to WebImageView controls.

    Any ideas ?

    I found a Feedback case that appears to document this issue...

    Feedback Case #54491

    I bet if you launch using the full path, your problem will go away.

    Nobody experienced this ?

    I have zero knowledge of this environment, however I would ask if your application when daemonised has access to the application resources folder?

    @Wayne G Thanks for your answer.
    I can't imagine that the daemonised app would have different permissions that the same app not-daemonised.
    How could this be checked ?

    @Wayne G I have zero knowledge of this environment

    a built version of a Xojo Project will include the images imported in the <app name>/resources folder. I would expect that if that folder was not available the images would be blank or not displayed.

    Sorry if you were to build a Windows server I could help more.

    Yes, on Linux, there's a "<app_name> Resources" folder containing all the images.
    I've checked the permission and they're correct.

    Hopefully you'll get some help when the Americans wake up. Sorry I couldn't help more.

    Check the process list and see what user the app is actually running as. Does it match the permissions?

    The app is running with a user named Ubuntu :

    ubuntu   25229     1  0 10:28 ?        00:00:25 ./SteadyBase -d

    The app is installed in /home/ubuntu directory and this user has all the permissions.
    If it was a permission issue, why does the non-daemonised version work perfectly ?
    BTW, the -d parameter is the one I check for daemonising or not.

    I've checked the process list when not daeminised :

    ubuntu   26312 23187 27 11:34 pts/0    00:00:03 ./SteadyBase

    could you run ls -al * on the app's main directory and post that here?

    Some more details :

    • when I start the webapp daemonised using root account, the issue is the same (no images displayed)
    • when I start the webapp non-daemonised, the images are displayed (no matter witch user is used)
    • when I watch the chrome developper console on the page, the images are all replaced with "https://backoffice.steady-sun.com/framework/spacer.gif" instead of the image's URL.

    Hope this helps finding a solution.
    It's becoming urgent, the app is ready but is not useable actually.

    Ok, first of all, all of the files in SteadyBase Libs should be set to 755 instead of 664. I don't think that's causing this particular issue, but may bite you later.

    when I watch the chrome developper console on the page, the images are all replaced with "https://backoffice.steady-sun.com/framework/spacer.gif" instead of the image's URL.

    This statement is very interesting. That means that the WebPictures aren't getting loaded at all and the default image is being sent.

    Do you happen to know if SELinux is running in Enforcing mode on this server?

    I've set all the libs permissions to 755.
    Enforcing is disabled on this server.

    What can I try next to solve this ?

    I gotta be honest, I'm running out of ideas here.

    The only other thing I can think of is that maybe the "current directory" is being set to something else when daemonizing your app.

    Could you add some code to your App.Open event to write the contents of

    System.EnvironmentVariable("PWD")

    to disk somewhere, and see what that is? it should be the directory where the app is running from, but I'm guessing that it's something else.

    @Greg OLone Thanks for your time, I appreciate your help even if we're not there yet.

    The PWD is /home/ubuntu/SteadyBase
    That's exactly what was excepted (app directory), I suppose.

    Is there any other interesting environnement variable I can check ?

  20. Greg O

    I can’t think of any others that would help.

    I’m assuming that you’re daemonizing because you want it to keep running when you log out. Have you considered running the app as a service instead?
