Nextcloud not stopping download

[elpedriyo]

Nextcloud version (eg, 12.0.2): 14.0.0
Operating system and version (eg, Ubuntu 17.04): Debian 9.5.0
Apache or nginx version (eg, Apache 2.4.25): 2.4.25
PHP version (eg, 7.1): 7.0.30

The issue you are facing:

Is this the first time you've seen this error? (Y/N): N

I came from last version of nextcloud to see if 14.0.0 solved it, but it doesn't as far as I see. The problem is that I have an external storage NFS and with the official plugin I add it to nextcloud as local, of course the NFS storage is mounted inside the system. Once I start downloading a big file, example: 20GB and then cancel it, seems like the server continues downloading it (don't know where) as the interface of RX is still receiving a lot of data, once the full file is downloaded in the server (I assume) the RX goes down again. If for example I pause a download file, both RX and TX go down, but if I just cancel the download it happens what it is described before.
Any idea?

Steps to replicate it:

1. Mount a nfs dataset in debian
2. Activate external storage plugin
3. Config the plugin so that files can be browsed
4. Start downloading and stop the download
   5 The interface Rx won't go down until the file is downloaded in the server

GitMate.io thinks possibly related issues are #7978 (After Upgrading to Nextcloud 13 Beta, Files Not Accessible (No Open, Upload, Nor Download)), #3496 (Nextcloud downloads are lacking xz compressed (LZMA) archive), #9854 (Nextcloud download problem Help please!), #5391 (2fa TOTP stopped working on Nextcloud 12), and #4480 (Nextcloud and his problems are not solved.).

I have tried also with a snap package mounting my NFS and adding it with the external storage plugin in nextcloud, but the same issue happens all the time, if I download a file from my browser and cancel it at any point my server continues downloading the file as I am monitoring the network interface

[elpedriyo]

Ok, I was wondering if it was a bug with the NFS protocol, apache or something else, but I have confirmed that it seems to be a bug of the external storage plugin as with FTP protocol is also happening the same.

Could you please take a look to fix it? :D

Kind regards

Hello,

Seems like I have discovered a core bug in nextcloud, I should say, regarding this issue, at which I didn't got any reply, it seems like there is no problem or relation with a NFS mount or the plugin itself.
Nextcloud continues "downloading" the file although it was cancelled because he continues reading it.

I discovered it by trying to download a big file (20GB) from my local storage, and saw that once the download was cancelled, nextcloud continued reading it, just discovered it with a simple iotop:

Does anyone have any idea on why is this happenning on a fresh installation?

Kind regards
