Fix filesystem permission issues #5372

Do I have to close this ticket because there has been no activity for over two weeks? |
|
@BlackIkeEagle sorry for the delay over 2 weeks. |
in the driver classes in Magento\Framework\Filesystem\Driver the getAbsolutePath could be called with a basepath and a path that is already absolute, so when the path is already absolute just return that with the scheme instead of concatinating basepath and path resulting in a faulty absolute path.

@okorshenko I noticed some of the changes I had in there already landed in the magento code base in a slightly different format but same behaviour. The question that remains is the check if we already have a absolute path is desired or not? |
|
@BlackIkeEagle could you please provide a reference to the changes that you mentioned?
If there is a use case when lack of this validation will cause an issue - yes, we need it. |
|
@okorshenko I don't remember what my original fix was anymore the other part of the fix that still is in here was because we were trying to write robots.txt and there was already a absolute path in so it concatenated to something like /var/www/magento/var/www/magento/robots.txt |

@BlackIkeEagle thank you for your contribution to Magento 2 project |
When you have configured some strict filesystem permissions to only allow the minimum required write access to the magento application there are some issues
for example:
we have an existing robots.txt that is writable, but the parent directory is writable.
When you create a sitemap and have the option checked to automatically add it to the robots.txt file, everything goes south. Because the assertWritable checks if the parent directory is writable which is totally not nescessary because the file is writable.
Additionally there were some inconsistencies in the filesystem directory stuff.
And as an extra there is an extra check to avoid concatinating the absolute basepath with a path that is already absolute. (this could for example cause basepath='/var/www/website', path='/var/www/website/robots.txt' if you pass in both to get the aboslute path the result would be '/var/www/website/var/www/website/robots.txt' which was not the goal, now it wil properly return '/var/www/website/robots.txt')
It would be nice to have these fixes backported to 2.0 and 2.1 because we have this sort of issues in our production environments at the moment.
