Defaults for max_execution_time, max_input_time in base.php not configurable

[oc33]

Steps to reproduce

1. Run Nextcloud on shared hosting server with strict limits on max_execution_time or max_input_time
2. Inspect error messages in admin interface

Expected behaviour

No error messages if .user.ini contains values for max_execution_time and max_input_time compatible with server constraints.

Actual behaviour

Settings > Logging shows error messages like

Error | PHP | set_time_limit(): Tried to raise runtime beyond limit (3600/180). at <path>/www/nc/lib/base.php#639 | <timestamp>

at a very high rate.

As a work-around, I modified lines 637-640 of lib/base.php to conform with the restrictions set by my hoster:

        //try to set the maximum execution time to 60min                                                                                                                                                                                          
        if (strpos(@ini_get('disable_functions'), 'set_time_limit') === false) {
            @set_time_limit(<hoster_conform_value>);
        }
        @ini_set('max_execution_time', <hoster_conform_value>);
        @ini_set('max_input_time', <hoster_conform_value>);

I tried to set max_execution_time and max_input_time to conforming values in .user.ini, but this did not have any effect, presumably because the code in base.ini contains hard-coded values.

The server works, but pollutes the log file with tremendously many messages.

Hi, So I've got a similar issue to yours, maybe. I get the following php error, that I get bombarded with like every half second:

set_time_limit(): Cannot set max execution time limit due to system policy at path/httpd.www/nextcloud/lib/base.php#629.

I'm curious about how you found out what your hosting restrictions are and where. Was it in the php interface or did you contact them directly to find out? I'm running on a shared server. What did you change any values to? Was it >3600 or <3600? I looked at the code in the base.php file, but I'm not confident to make any amendments?

[oc33]

@night-light My hoster has posted the restrictions in their documentation. The values my hoster allows are much shorter than 3600s. The only changes I made to the code was to enter suitable numbers in the locations marked <hoster_conform_value> in my post above, replacing the default 3600. I need to redo this every time I update my installation, as it overwrites the base.php file.

[night-light]

@oc33 thank you for your reply! It looked like the set_time_limit is disabled for me and the hoster can't do anything about, not even provide me with the value for some reason as it wasn't possible, they say.

[thrdroom]

I have the exact same issue but with different needs. I want to set the max_execution_time and max_input_time to 7200 but base.php forces me to "3600". No matter what value i put into php.ini .user.ini or .htaccess - it always gets overwritten by the base.php.

As i want my config to bet update-proof, i don't want to use the workaround by changing the base.php.

This behaviour should be changed, as otherwise the instructions about max_exeecution_time in the documentation are useless Uploading big files > 512MB

As others have noticed the issues seem to start here: https://github.com/nextcloud/server/blob/v15.0.5/lib/base.php#L623

My workaround was to set all of those as php_admin_flag/values in my PHP-FPM config. That way there is nothing nextcloud can do to change those values.

This issue has been automatically marked as stale because it has not had recent activity and it seems to be missing some essential informations. It will be closed if no further activity occurs. Thank you for your contributions.

As there is no feedback since a while I will close this ticket. If this is still happening please make sure to upgrade to the latest version. After that, feel free to reopen.

@skjnldsv The values for set_time_limit(), max_execution_time and max_input_time (and also some file-size limits) are still hardcoded in base.php l 617ff. They should be configurable.
