Subject: trending: shorten error messages
X-Git-Url: https://gerrit.fd.io/r/gitweb?p=csit.git;a=commitdiff_plain;h=b022196c957892cc5748cf6fa688776be81a7219

trending: shorten error messages

Sometimes error messages are longer than 1000 chars. This change
looks for [;, :, '] in messages between 128 and 256 character.
If it finds any of these the error message will be cut from
beggining to this character. If there's no character from the list
in error message and message is longer than 128 chars. It will
be cut from beggining to 129 character of error message
