Write access notification despite plugins directory being writable

dhealy · September 6, 2019, 3:50pm

On IIS 10, Windows Server 2012 Matomo displays a notification “Matomo couldn’t write to some directories (running as user ‘nt authority\iusr’)” despite this user having full control of the plugins directory and its contents granted via icacls D:\Websites\matomo\plugins /grant:r "NT AUTHORITY\IUSR":F /T

Matomo is able to install and activate plugins from the Marketplace without issue, so I’m guessing this is a bug. I’ve hidden the notification for our analytics users via custom styles imported into main.less:

div[notification-id="CorePluginsAdmin_InstallPlugin"] .notification-error {
	display: none !important;
}

Hi there,
Thanks for the feedback. Can you maybe check that the user also has permission to update all sub-folders of plugins/ folder? Maybe the problem is that an existing plugins/XYZ folder (or a sub-folder) is not writable?

Hi Matthieu, I can confirm that IUSR has “full control” permissions, inherited all the way down to all subfolders (the greyed out icons in the “Allow” column shows that permissions are inherited from the parent “plugins” directory) and is the owner of the parent “plugins” directory and its contents.

As noted, Matomo is able to install and activate plugins from the Marketplace without issue, so I’m guessing this is a bug.

Same problem here on Ubuntu.
Installed Matomo last week, everything was fine. Today I tried to install the BotTracker via the market and now it’s showing this message wherever I go.

Even changing www-data to be owner of everything and giving full write permissions (including sub-folders) didn’t help.

Hi,

This is an annoying bug in Matomo that is in the process of being fixed.

Bug Help wanted c: Usability not-in-changelog

quite low priority, but I wanted to write it down just in case I stumble across …it again in the future. (and maybe the same is true for other error messages and it confuses user) When developing Matomo doesn't have write permission to `plugins/`. This doesn't matter as it isn't needed for things apart from the marketplace. When one tries to download something from the marketplace this error message appears rightfully: ![grafik](https://user-images.githubusercontent.com/6266037/74612027-b0212200-5101-11ea-865e-6396dec7bf23.png) The issue is that there is no way to get rid of the notification. Pressing the x only closes it with JS, but as it is rendered by Twig it will reappear on every page even when it doesn't matter anymore. Adding a `static::$session->unsetAll();` to https://github.com/matomo-org/matomo/blob/b16a791aa3650d85af829156129c2bd44c7cb075/core/Notification/Manager.php#L191-L202 removes it from the session and gets finally rid of the message (ending the session in another way would also work).

The message appears when Matomo can’t write a file, but doesn’t disappear after you fix the permissions. You can log out and log in again to remove it.

And revert your permission as at the moment everyone on your server can read and modify all Matomo data
