Description Aaron Williams 2020-07-29 04:21:19 UTC

SUMMARY


STEPS TO REPRODUCE
1. Click "New Message"
2. Start typing in the name of a frequent recipient address
3. After the first three letters are typed it hangs and consumes 100% of the CPU.
Note that if I type in the complete email address elsewhere and copy and paste it then it works just fine.

OBSERVED RESULT
Hangs when typing in the email address

EXPECTED RESULT
It should not hang and offer matching email addresses

ADDITIONAL INFORMATION

Comment 1 Aaron Williams 2020-07-30 04:46:44 UTC

I have some more information. It's getting stuck in an endless loop in QStringList ContactCompleter::complete() where it keeps getting the exception a Xapian::DatabaseModifiedError exception when it tries processEnquire. It reopens the database and retries endlessly and never completes.

Comment 2 Aaron Williams 2020-07-30 05:03:49 UTC

It looks like my emailContacts database was corrupted and xapian could not fix it. Deleting the database fixed it. I think a never ending loop may be a problem with this exception. A better solution might be to pop up a message after a certain number of retries.

We can't add a messagebox for the moment so I added a warning.
