tempdirectory at the update and after

[Ralf99]

Hi,

I have the following problem.

I updated my NC v11.0.3 (test-system) to the v12.0 beta4 on a sharehoster.

1. I opened the "web-updater" and started him.
2. I get the following Error

Check for expected files
The following extra files have been found:
tmp

3. I follow the instructions from this posting (https://help.nextcloud.com/t/update-problem-check-for-expected-files/6104/18) and enter this 'tmp', to the directories.
4. I restart the web-updater -> it works like a charm.
5. On the new System (NC v12.0 beta4) i go to admin -> logging and find now many many Errors and Warnings :(

Error PHP opendir(/tmp): failed to open dir: Permission denied at /www/htdocs/xxxx/lib/private/TempManager.php#189
Warning no app in context Temporary directory /www/htdocs/xxxx/tmp is not present or writable 2017-05-18T17:04:00+0200
Warning no app in context Temporary directory /www/htdocs/xxxx/tmp is not present or writable 2017-05-18T17:03:29+0200
Warning no app in context Temporary directory /www/htdocs/xxxx/tmp is not present or writable 2017-05-18T17:03:00+0200
....

6. If I look now on the ftp root i can´t find a "tmp" folder. But when i create it manually again, the Warnings and Errors disappear from the logging.

Is this normal? If NC need this temporary directory, why delete the updater then this folder?

because we don't expect it in the Nextcloud folder itself. Usually this is in a completely different partition of your hard disk. :/

Same problem here with a webhoster that offers one-click install of nextcloud. They place a "tmp" directory in the nc root.
This simple install makes nextcloud available to users with almost no tech skills, but they won't be able to do updates, hence worsening security of these instances over time.

Proposal @MorrisJobke: Couldn't updater check config.php for the location of the temp dir and accept it inside the nc root if it is defined in the file?

Should probably be consolidated into #68 (which would cover this for tempdirectory - and more).
