[Former user]

Hi,

Hi, unluckily it does not fix the warnings. In the daily-report.php there are 3 Lines less, but the generate_stats.php is not changed.

set the following in your php.ini

#!

error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED & ~E_WARNING

[Janos SUTO]

What version do you have? Is the gui version 1.1.1?

[Former user]

Yes, current stabke version.

[Janos SUTO]

I think something is not right on your side. "Undefined variable: ssize " says your tables are not updated. Check if the util/db-upgrade-xxxx.sql scripts were actually applied.

[Former user]

Hi,

it was a clean install of 1.1.1, so I initially executed the db-mysql.sql script.

Also the Undefined variable: ssize comes from the memcached acces. The _piler:size key exists, but the _piler:counters_last_update does not (see line 14 in counter.php). Might that be a problem?

[Janos SUTO]

Just fixed these scripts again. Please try them, this time try turning off memcache support.

[Janos SUTO]

No news is good news.

[Former user]

Sorry, I was onl holidays :-)

I tried the newest scripts from master/HEAD - no visible change.

With MEMCACHE disabled:

BTW: What exactly is Memcache used for? Is it usefull to enable? (actually I just did it, since I couldn't find any deeper explanation in the docs).

Thanks a lot!

[Former user]

sorry to reopen :-)

[Janos SUTO]

Please send me your config-site.php (obfuscate only passwords). See my email in piler -V

[Former user]

on its way

[Janos SUTO]

Thanks. Try removing the trailing ?> from the file, and let's see if it helps.

[Former user]

Arggggh... That on was too easy... Actually it works. Thanks!!!!

The Memcache related error persists: Should I just disable memcache?

[Janos SUTO]

There must have been an extra line at the end of the file. I could have thought about it sooner, indeed. I'll check the memcached related issue, until then you may disable it.

Btw. I've applied the init script fix recently (thanks for that anyway), though I didn't pull your your fork.

[Former user]

Thanks again!

[Janos SUTO]

Regarding the memcached problem, I think the daemon doesn't write the counters to memcached (but rather directly to the counter table), that's the reason of the missing variable.

Update model/stat/counter.php with this file: https://bitbucket.org/jsuto/piler/raw/b4867d79fe3d398b7f1a80603cc659be8f1cbcb8/webui/model/stat/counter.php and it will be ok now, regardless of the memcached settings.

[Former user]

Thanks. Since it's just removing the memcache logic, it's working fine.

Done.... :-)
