Redmine plugin showing logs for outgoing emails

Added by 7 months ago

Sometimes it’s important to know, if the user should have received the email notification generated by Redmine. Especially, if usage of Redmine in your organization relies on email integration (for example, if it’s configured to receive user comments, such as issue notes and message replies, via email). In such cases, some users may use Redmine user interface very rarely as all the communication can be made through emails.

Until now it was impossible to determine using Redmine, if the particular email notification was sent to the particular user. For this, you would need to dig into the logs of theĀ message transfer agent (MTA) (if you had access to those logs, of course). Even so, it was not easy to link records in such logs to certain email notifications.

4-byte UTF-8 problem in Redmine and how to fix it

Added by 7 months ago

I’ll start with explaining the cause of the problem. If you don’t need this, you can skip the padded paragraphs.

You have probably already heard about issues with weird symbols in iPhones, that led to freeze or reboot? Something like these can also be experienced on Redmine instances, that were installed some time ago. iPhones crash because they fail to render the weird symbols and such Redmine instances give errors because they fail to save corresponding symbols to the database. Yes, the problem is actually in the underlying MySQL database, not in Redmine. In iPhones this happens with some unusual 4-byte unicode symbols and in Redmine/MySQL this can happen with any 4-byte symbol. Thus, you can experience this issue in Redmine with emoji, some Chinese, Japanese and Korean characters.
