PHP errors when sending alarm emails

gjpc 2019-04-30 16:12:41 UTC #1

Hi All,

I have a new error email showing up. I believe it is related to Egroupware sending calendar alarm emails. The cron process is generating the error output. The alarm emails are successfully sent, but there are messages:

PHP Warning: preg_replace_callback(): Compilation failed: invalid range in character class at offset 91 in /usr/share/egroupware/api/src/Html.php on line 55

#9 {main}

(The user name is redacted with XXXX in the above log)

There are no non-alpha characters in the name of the alarmed appointment.

I am running:

egroupware-epl (17.1.20190402) hardy; urgency=low
Package installation
PHP Version 7.2.16-1+ubuntu16.04.1+deb.sury.org+1
Apache 2.0 Handler
MySQL

Any suggestions?

Hi gjpc,

do you know how long this has happened?
Is that only the case at this one appointment (CT sc…)?
Can you make the appointment available as ics (for me)?

Greetings
Stefan

Hi Stefan,

I looked further, and I noticed the emailed alarms do not have the description of the event in the email body text. This started when I upgraded to 17.1.20190402.

These php error messages just started with my most recent alarms 5 days ago.

I would be happy to send you an ics of a different event, please describe the procedure for me to do this.

Best,
Gerard

Right-klick on the event => Export iCal

Best is the date belonging to the notification:

Stefan

Here is the ICS file, I have upgraded to the new release and the problem still exists.

This PHP Warning is fixed now:

You can also replace the whole file:

Thanks for reporting the issue

Thanks for your attention Ralf. There are a few more malformed regular expressions in the Html.php file with the same error. I corrected them and now the alarm emails contain the full description. Here is the Html.php diff:

50c50
<               $Domain = '([\w-]+\.[\w\-.]+)';
---
>               $Domain = '([\w\-]+\.[\w\-.]+)';
64c64
<                       $Domain = '([\w-]+\.[\w-.]+)';
---
>                       $Domain = '([\w\-]+\.[\w\-.]+)';
95c95
<                       $Domain2 = 'www(\.[\w-.]+)';
---
>                       $Domain2 = 'www(\.[\w\-.]+)';

However now the cron supplies a new little gift for each delivered alarm email. I think this may have to do with my upgrade from PHP5 to PHP7. The error occurs in the egroupware directory but it is in the pear horde:
