File uploads larger than 1MB fail

[sonic331va]

Android Version: 4.4

All files larger than 1MB fail to upload. Files smaller than 1MB upload successfully.

Chunked file handling is included on the server in filesplugin.php.

I'm breaking this out of the comments of #306 since my issue appears to be different.

[davivel]

Ok, I didn't see this before. Thanks for open it. Let's see when we can deal with it,

[ajincitti]

@davivel any update on this issue?

[davivel]

No, sorry. Looking for a time box.

[mtschaef]

I'm getting this same exact issue with the chunking of uploads receiving a 404 on the first file.
I have full control of my own personal server.
Server running the latest 6.0.3.
Android client the latest 1.5.5.

From the owncloud Admin page error logs:

Fatal webdav Sabre_DAV_Exception_NotFound: File with name InstantUpload/IMG_20140510_181857.jpg could not be located

Debug OC\Files\Cache\Scanner !!! Path 'files/InstantUpload/IMG_20140510_181857.jpg' is not readable !!!

[davivel]

Hi, @mtschaef . We would really appreciate some logs here from the web server to compare them with those of @sonic331va .

@sonic331va , is it possible you have some kind of size limit for uploads in your Apache server?

[sonic331va]

@davivel I specifically went through my webserver to disable upload limits, memory limits, etc. because we do upload large files often. Large file uploading works fine from the web. It's just the file chunking that is failing.

[davivel]

Are you still woking with the same owncloud server version? Did you upgrade, but is it sill failing?

[sonic331va]

Unfortunately, I have not had time to spend on the server in the past couple of months. The uploading issue sort of put a pause on using owncloud. I will try with the latest updates when I can and let you know the outcome ASAP.

Below are the two logs from the
server. The first is the Apache access log file and the lower one is from
the Owncloud.log file.

As soon as I connect my phone to a WiFi connection if uploads successful
with no problems. (I can send those logs as well.)

[davivel]

@mstchaet , so it only fails for you when you try to upload from the Internet, but it works when you do it from the WiFi LAN?

The problem is not the 404 response in the HEAD method - that's expected. The problem is the 400 response por the PUT method later.

Please, could you follow the instructions in the next thread and see if something of that helps?

https://forum.owncloud.org/viewtopic.php?f=17&t=7536

[mtschaef]

@davivel , I have looked over that thread and nothing sticks out as being the issue with my setup.
The problem that I'm seeing is that it only happens when I'm on my cellular network.
I'm starting to think that this might be something with my provider. I don't know how I go about proving it to them or getting them to make a change if needed.

[davivel]

Do you mean mobile network provider, or hosting provider?

[mtschaef]

Yes mobile network provider. This is only happening on my cell phone.
I host my own server at my house.

[davivel]

Did you try to upload something through a Wi-Fi that is not in your home? I would discard problems about routing, proxies or firewalls before thinking in contrains by the cell phone provider.

[mtschaef]

This is only outside of my house. I don't ever upload from my home's WiFi.

[koug44]

I have the same issue on Wifi (everywhere home, work…)
Upload fails for any file bigger than 1Mo

Server: 6.0.4
Client: 1.5.7
PHP: 5.4.4-14+deb7u11

First try with picture is failing, as second one with small text file is working

[davivel]

@koug44 , could you try with a file that is bigger than 1MB, but not an image?

Thanks.

[koug44]

@davivel , tried with an MP3 file over WiFi. Still failing

It may be related to chunked transfert encoding (which small transfer doesn't use)

[koug44]

I tried once more with an apk file

It always fail at exactly at 1160 bytes, whatever the filesize is.

[mtschaef]

Update to the issue I was having:
It appears that this was my ISP/Modem/Router. The Modem/Router failed at our house to which I had to replace. After replacing it with the new one everything started working again. My files now upload 100% of the time no mater the size or the clients connection source (LTE or WiFi).
This is very perplexing to me other than maybe my router wasn't communicating the traffic correctly on the status updates when the file doesn't exist.
Thanks for all of your help and I hope that this helps somebody else in the future.

[davivel]

Thanks, @mtschaef, for the update.

@koug44 , sorry for coming back so late. Is this still failing for you? Did you try to upgrade to OC7 and Android app 1.5.8?

Another thing I am noticing... all the logs you showed involved folders with © or à characters in their name; that could be a factor. Could you try to upload some files of different sizes to the root folder of the account, or to some folder with only alphanumeric characters without ticks on?

Thanks in advance.

[koug44]

@davivel OC7 with App 1.5.8

I tried twice over wifi (work) with and without spaces in filename

[sonic331va]

@davivel I was finally able to get back to this project of mine. I installed the latest server and it looks as though server 7.0.2 and the latest owncloud app from the play store are working for me. Files larger than 1mb are uploading as expected.

Thank you very much for your continued hard work on this project.

[davivel]

@sonic331va , great news!!!. You're very welcome, but I do not deserve compliments, there are many people here not writing so often but working a lot.

@koug44 , is an upgrade to OC 7.0.2 possible for you, or is your server already there?

[koug44]

@davivel Server already there (7.0.3 to be precise). No improvement seen

[davivel]

@koug44 , what app do you have in your OC server?

Is encryption enabled? If it is, try to disable it temporary and upload something from the app.

[bislewl]

I'm having the issue with a vanilla version of 7.0.4 uploads > 1MB are failing.

[davivel]

@markcs , sorry for coming back so late. Could you reproduce it again and copy also the logs in the server side? Specially owncloud.log, in your case. There is an internal error in the last chunk upload.

@bislewl , could you upload some logs from your server too?

Thanks.

[koug44]

Got news (almost good one). Still with the same server OC (now on 8.0.4)
Both official clients are failing to upload files (desktop and android)
Upload via web interface is still ok (using Firefox)

But now, I can also upload my pictures from my Android phone using QuickPic app and Owncloud integration. It's working fine for the same files than official client can't upload.
Could it be useful ? I'm guessing they are not using the same HTTP method or syntax

at owncloud/core#9832 respectively https://doc.owncloud.org/server/8.0/admin_manual/configuration_files/big_file_upload_configuration.html#apache pointed out some hints that helped for some, but not for me ;/

[koug44]

The bug is fixed for me, both with Android and new 2.0 client.

I've fixed the PHP cache a few days ago. It may be related

[childnode]

unfortunatly it isn't for me, not even on android, other related issues: owncloud/core#17712 so it not just seems to be an android / client bug hence it worked fine prior OC 8. as it is pointed out there: it is caused by buggy PHP 5.4, you need to upgrade

update: yay back ... OC 8.2.2, php 5.6.17 and .18 with any webDav client ;( that's sooo frustrating,
owncloud/core#9832 > owncloud/core#22426

[davivel]

@ALL, please, could you confirm if this is a problem for you with OC 1.9.1 for Android?

Thanks in advance.

[childnode]

so, can confirm this doesn't work for me with 1.9.1 (upload a 2,5 MB PDF just got stuck at 0%) but I also can't check back for older version since I have removed it due to the annoying power sucking bug.

But I ran into 2 other bugs ;) and once again: I think it's more a core than an android bug.

[sprin]

I encountered this problem when attempting to upload any file > 1 MB from my phone via GSM. It happens consistently on GSM, but not on a WiFi connection. I found a way to consistently replicate it regardless of network/hardware.

Server (created for replicating the bug, using a very simple recommended config):
CentOS Linux release 7.2.1511 (Core)
PHP 5.5.21-4.el7
Owncloud 9.0.0-3.1
MariaDB 1:5.5.44-2.el7.centos
Apache 2.4.6-40.el7.centos

Clients:
App Version 1.9.1
Phone: Android 5.0.2
Desktop Android Runtime: ARChon 1.2

I was able to reproduce from my desktop by simulating the latency, packet loss, and reordering of a non-ideal GSM network with the netem kernel module:

sudo tc qdisc add dev wlp2s0b1 root netem delay 3000ms loss 25% reorder 50% 50%

I used a test file created by dd:

The exception logged on the server always follows the format:

This appears to be the related request logged by Apache:

31/Mar/2016:16:25:06 +0000] "PUT /remote.php/webdav/testfile-chunking-4629-2-0 HTTP/1.1" 400 225 "-" "Mozilla/5.0 (Android) ownCloud-android/1.9.1"

Additional notes: I have not seen this problem with either the web client or the Linux desktop sync client under the same network conditions. I have only seen the problem under non-ideal network conditions with the Android app. The client reports an error immediately after reaching 1MB while uploading.

The Owncloud Antivirus app causes these problems:

owncloud/files_antivirus#110

If I disable it, upload works fine again.

Most likely fixed with owncloud/core#24653 in all the upcoming server maintenance releases.

[davivel]

@MorrisJobke , that would be really awesome. Thanks a lot.

[davivel]

@childnode, @sprin, @e-alfred : is this still a problem for you? Did you upgrade your servers to one of the latest maintenance versions (9.1.0, 9.0.4, 8.2.7, 8.1.9 or 8.0.14) ?

Thanks!

[childnode]

hi @davivel , yes, I updated to 9.1 in the meantime but was anyway not able to reproduce this in any release since #402 (comment) nor with owncloud client 2.0 ...anyway. I switched to nextCloud and I can confirm nextCloud client 1.2.0 (no idea which owncloud client it is forked of) works in my setup. ... if there is any problem: I can't reproduce it anymore nor can I help to track down which versions / combinations of app and server won't work and which will...

[davivel]

Thank you so much for your answer, @childnode :)

Will wait a bit more for answers of @sprin and @e-alfred before closing.

[davivel]

@Sprint, @e-alfred. I'll assume this is not a problem for you anymore.

Add a comment if I'm wrong.

Thanks!

I'm on the second latest stable version of OwnCloud (Serverside) and I'm using the client from F-Droid on Android, and the problem still occurs for me. It was gone with 9.0.2 but it returned with 9.0.4.

edit: I do not have the AntiVirus app installed

[davivel]

@typorian , could you open a new issue and give us some more details about your environment? Take a look to the issue template.

Thanks!

[e-alfred]

It works well now with Owncloud 9.1.0, Android client 2.1.1 and Antivirus app 0.9.0.0.

[typorian]

@e-alfred I'll have my provider upgrade owncloud for me and hope that I get the new client version soon on F-Droid. If that makes it work again, I'd be happy.

[e-alfred]

It still happens with the antivirus app activated. After disabling it, the uploads work well on 9.1.1.
