WebDAV remote connection to PowerFolder doesn't fetch existing files, multiple PHP Errors #11242

ChargingBulle · 2018-09-16T15:07:25Z

TL;DR Remote via WebDAV. remote files are not downloaded. Files added on my side sync. Maybe lasttimestamp-issue?

Steps to reproduce

Add WebDAV remote via user + password
HTTPS enabled
remote get's "green circle". Everything seems to work.

Expected behaviour

Expected4) Examine: either [progress with scanning folder structure is happening] or [some progress bar that reports "hey we're still scanning the remote]

Actual behaviour

Actual4) Examine: Folder is empty
Actual5) add a file and check powerfolder remote, the file is properly synced from my instance to theirs
Actual6) delete the same file and check again: also workd
Actual7) Think "oh well maybe it needs a while to discover all files and folders on the remote"
Actual8) wait >24 hours
Actual9) still empty folder. Remote is still green. Check log. See PHP errors. Report bug.

GitMate.io thinks possibly related issues are #3738 (Webdav), #6784 (Php error?), #681 (WebDAV: "409 Parent node does not exist" when using remote.php/webdav/ to upload files), #4201 (Multiple Errors), and #8795 (webdav link should point to remote.php/dav/files/).

problem persist

linuxrrze · 2018-09-18T05:27:24Z

Powerfolder had (and has) a long list of (webdav) problems.

One of them is webdav folders being shown as empty even if they contain files.
Even using different webdav clients to access the folder gives the same error -> server issue.
To make things worse, it works sometimes, but once it doesn't there is some kind of server-side-caching mechanism, that prevents a simple reload to "fix" the issue.

Bug has been reported to Powerfolder but is not fixed (yet).

ChargingBulle · 2018-09-18T07:11:43Z

Thanks for the quick answer.
I'll ping my PF admin and maybe pivot away from PowerFolder to either Alfresco (which supports WebDAV bestter as far as I know) or self-hosted NextCloud.

We're pivoting away from the big cyan box and tbh pivoting again would be a toughs sell 🤕
Any chance to get PowerFolder working via FTP / Briding / ... ?

linuxrrze · 2018-09-18T09:26:03Z

Based on our experience I wouldn't count on Powerfolder implementing an additional new protocol without a paying customer forcing them to do it. And even if they did I wouldn't dare using it in production (at least for a few years).

And a general note: I think it's a bad idea to use one sync & share solution (that's accessible via webdav) as a storage backend for another sync & share product. My guess is, that performance will be far from optimal.

ChargingBulle · 2018-09-18T13:02:28Z

We're using the academic-tier of PowerFolder. I arranged the creation of an NextCloud instance using university hardware. Maybe I can pivot other students to use NC instead of PF.
That way I can sync university NextCloud with my personal NextCloud (yay for federation!)

It's trivial to deduct what university I go to. According to my internet searches on PowerFolder instances we're basically the only people in the world who seriously use PowerFolder 😒.

My recommendation: don't. The Web UI is horrible and the overall featureset and design is not competitive when compared to NextCloud/Dropbox/basically-anything-that-stores-data.

Disclaimer: this is my personal opinion on PF and I'm not a statement from my uni and/or any roles I hold at my uni.

linuxrrze · 2018-09-18T15:54:42Z

Maybe sometime in the future federated file exchange between different vendors will be possible:

I'd love to see that!

Correct. I would close this ticket here for now as @JonasDralle tries to move away anyways.

Thanks for the feedback nevertheless.
