@pako81 I adjusted acceptance tests to include some cases with a user with + in the username. And also added a changelog entry.

IMO this works. @micbar this could be merged for 10.4 - is that OK?

[pako81]

thanks a lot @phil-davis :)

[pako81]

@phil-davis I was now thinking about the user provisioning APIs. In there, the + sign is still not correctly escaped but rather replaced with a space character.

[phil-davis]

@pako81 I added provisioning API tests. They are passing locally for me and I expect that they will pass in drone CI.
Probably the tests are providing the + in the URL as ASCII 43, %2B (I think that is true, without actually digging deep into the test code)
And that is how any client using the Provisioning API would need to specify a username containing a + - and the backend code will receive the %2B turned back into a + and it "just works"

[pako81]

@phil-davis correct, I was testing the wrong way. The following seems to work correctly.

curl -X POST http://admin:password@example.com/ocs/v1.php/cloud/users -d userid="name%2B1@test.com" -d password="test"

User name+1@test.com is correctly generated.

[phil-davis]

There have been other major features merged just now. So I rebased this PR to make sure that the CI is all green on top of those changes now in master.

[phil-davis]

@micbar @HanaGemela I have added acceptance test coverage and it passes (adding users with + in ther username via the webUI, cli and provisioning API and doing stuff with them...) So this looks like it works fine.

I some developer can review the code and approve, and you think this is a change/enhancement that we should have, then feel free to merge it for 10.4

LGTM 👍

[karakayasemi]

Everything seems good. As a last, this should be adjusted also.

core/core/Command/User/Add.php

Line 67 in 98922f1

'User ID used to login (must only contain a-z, A-Z, 0-9, -, _ and @).'
