Quoting Arjen de Korte <build+ho...@de-korte.org>:
Citeren Arjen de Korte <build+ho...@de-korte.org>:Citeren Arjen de Korte <build+ho...@de-korte.org>:Just a heads-up for those that what to upgrade to PHP 7.3: it seems like there are some incompatibilities with Horde (master) in handling regular expressions.Some (but not all) messages will not display content.It looks like HTML mail is displayed correctly and text-only ones don't.The following is logged for each message:2018-12-25T12:47:27+01:00 WARN: horde [imp] PHP ERROR: preg_replace_callback( ): Compilation failed: invalid range in character class at offset 68 [pid 2076 on line 99 of "/usr/share/php7/PEAR/Horde/Text/Filter.php"]2018-12-25T12:47:27+01:00 WARN: horde [imp] PHP ERROR: preg_replace_callback( ): Compilation failed: invalid range in character class at offset 649 [pid 2076 on line 99 of "/usr/share/php7/PEAR/Horde/Text/Filter.php"]This may be due to the stricter interpretation of character ranges in classes.Note that the message content is available. I can reply to such a message (like the one quoted above) just fine. So the trouble seems to be in rendering messages, rather than grabbing them from the IMAP server.
Any chance you can get a stack trace to see where the regexp is coming from? I can't reproduce this on a fresh VM I spun up with php 7.3 and current git master.
I did find some regexps that needed to be fixed, but I dont' think those are called when just displaying an email. See: https://github.com/horde/imp/commit/5186ad002b0809960fd6096a2ca85ab8d2aab888
Also, please make sure you are up to date with git on *all* packages. I know there were a few similar fixes not *too* long ago in some other packages, like Text_Filter.
