"Failed to lock the file" error after installing Shaarli

[uraza]

Hi.

I am new to Shaarli and I just set it up on a shared hosting.

After copying the files on my server, I was able to access it and all requirements seemed to be fulfilled:

However, after clicking the "Install" button, I ended up with a bunch of errors like this:

An unexpected error happened, and the error template could not be displayed.

Failed to lock the file.

It only fails if I am logged in.
Removing the cookies and accessing the page is fine, until I try to log in again.

Any idea what could be wrong?

Thanks.

Hi, does data/datastore.php exists? Otherwise can you try to create it manually, and make sure it's writable.

Hi @ArthurHoaro

The data/datastore.php file was missing so I created it (as empty) and made it writable.

Here is the content of my data folder now:

The same error happens when accessing Shaarli though.
The log.txt file shows my successful logins to Shaarli but no other information.

I looked more precisely at your exception and it looks like flock function is not working, probably due to the setup of your shared hosting.

I will provide a PR to make this error non-blocking.

In the meantime you can either rollback to v0.12.0 or manually put following line outside of this if in the code:

$mutex = new NoMutex();

It works with that change (I also had to remove the empty data/datastore.php created yesterday).
I will let you know if I find anything else, shared hostings can have weird setups from time to time.
Thanks for the help!

Same thing happens at gandi.net
