Archive.php not working any more via cron in 2.1 RC1

Support & Bugs

Hi!

After updating to 2.1 RC1, my cron running archive.php is not working any more (the cron is still running but the archive.php gives an error):

archive.php --url=https://my-url-to/piwik/

Error in the last Piwik archive.php run:

Here is the full errors output:

I assue that this must have to do either with the force SSL (I was using SSL before!) and/or the new super user features.

Any ideas?

It seems that the archive.php now tried to access /proc/version/ to determine the Linux version. When I run this at command line I get:

cat /proc/version/
cat: /proc/version/: Permission denied

So it seams that on my server this feature is not available. Maybe you should not rely on that since due to security reasons, proc/version might not be available on all systems.

Thx for reporting this issue! I just pushed a fix to the Piwik master and should be available in next beta/rc release.

I get this error in Piwik 2.2.1 still. I have updated from Piwik 1.x so I don’t know if it was working in Piwik 2.1 after the fix that was mentioned.

Can you please copy the full error you get from the error log or syslog?

Is it still this?


cat /proc/version/
cat: /proc/version/: Permission denied

Maybe we will need access to your server to reproduce and fix it, if you dont mind

$ cat /proc/version
cat: /proc/version: No such file or directory

Looks like /proc is really not mounted on our shared hoster:

$ mount
none on /proc type proc (rw)

oK, would you please email to matt@piwik your SSH access to Piwik so I can reproduce? I should then be able to find the bug and fix it in piwik. thanks!

mounted /proc and not mounted /proc is both a “stream” resource type. So is_resource() is not sufficient enough to test if /proc is really mounted or not I guess.
create an empty folder somehwere and then compare

get_resource_type(@fopen('/proc', 'r')
get_resource_type(@fopen('/empty/folder', 'r')

@Klaus can you please comment on the related ticket: procfs needed by process component as of Piwik 2.2 · Issue #5041 · matomo-org/matomo · GitHub

feel free to re-open it, if that’s not working for you. It’s important we get this fixed :slight_smile: thanks
