Cannot fetch directories and app crashes on top-level files when extra trailing slash in server URL.

[risacher]

Steps to reproduce

1. Connect app to server with extra trailing slash in the URL - ie. "https://FQDN/owncloud//"
2. Try to fetch any directory or file

Expected behaviour

Tell us what should happen

Show directory content or file

Actual behaviour

Tell us what happens instead

All directories show "Folder Removed" error, "This folder no longer exists on the server."

Inspection of network traffic indicates that the app is attempting to GET the following path: "/owncloud//remote.php/dav/files/dan/owncloud/remote.php/dav/files/dan/documents/"

Attempting to open a file from the root directory crashes the app.

Alternatively, the iOS app should either delete the extra slash or give error message. But it connects and can fetch the top-level directory okay, which made it hard to figure out why it wasn't working.

Thanks for reporting this issue @risacher!

The issue should be fixed as of 3266cfa (and in an upcoming TestFlight build that will be part of).

@risacher did you check with a newer build?

@risacher did you check with a newer build?

didn't published a new build on TestFlight. sorry

[jesmrec]

ok, i will try to get a server with double slash... with subfolder is easy to build, i will check other options.

The fix is already merged inside #167. Let's wait for additional feedback before closing.

I just tested with TestFlight build and seems fixed to me.

https://myserver.org/owncloud// is changed to https://myserver.org/owncloud/ and then works.

interestingly, extra slashes internally (e.g. https://myserver.org//owncloud/) just "work". (Unsurprisingly, since the web server ignores these.)
