Continuing the discussion from Development Roadmap 2019 - Robust Backup Process :
I have been running EmonCMS on Lighttpd for several years now quite happily. Unfortunately, it seems that the setup will not follow symlinks.
I have explicitly enabled it to follow symlinks without success.
When I did the install, I had to fiddle with the rewrite regexp to get it to work and my suspicion is that this is what is not working.
Anyone like to suggest what might be breaking it?
url.rewrite-if-not-file = (
"^/emoncms/([^?]*)$" => "/emoncms/index.php?q=$1",
"^/emoncms/([^?]*)\?(.*)$" => "/emoncms/index.php?q=$1&$2"
)

I know this is root, but by default everything is done as root on DietPi (let’s not go there).
If i try
/emoncms/graph/view
I get the graph page, if I try
/emoncms/backup/view
I get an error
URI not acceptable. No controller 'backup'. (view/)
Should that URI work?

I’m not the best at PHP, but when I look at the code I would “not”.
/emoncms/graph/view would land in the “else” here and open the view.php page
as there is no explicitly defined view action.
Whereas with /emoncms/backup/view there is no defined view route OR else to catch the view url. The backup_view_php seems to be served at /emoncms/backup ie when there is no action defined.
In contrast, the emoncms/input (for example) seems to have the view action explicitly defined, and it will open either the input_view.php or device_view.php depending on the users “beta” setting.
} else if ($route->action == 'view') {
$route->format = "html";
textdomain("messages");
$ui_version_2 = $user->get_preferences($session['userid'], 'deviceView');
if ($device && isset($ui_version_2) && $ui_version_2) {
$result = view("Modules/input/Views/device_view.php", array());
} else {
$result = view("Modules/input/Views/input_view.php", array());
}
To test the above theories I navigated to emoncms/graph/carrot and still landed on the view page, so any undefined word will take you there not just “view”. I don’t have backup installed but I’m guessing you will find it at emoncms/backup

No it is under Modules.
Solved it - it was a permission issue
Actually that code (in core.php) could be simplified to a file_exists for each of the folders found. No need to check for the link or dir really.

We were discussing url paths rather than FS paths I meant http://emoncms/backup not it’s installed (symlinked) location.
As in
I don’t have backup installed but I’m guessing you will find the view at emoncms/backup

Ah yes. in the end, with the right permissions, /emoncms/backup works.
Cheers
