Notification system shows warning/error when the project domain contains Unicode characters

[raphael.schmid@…]

No idea if this issue exists for URLs that have a Unicode character in their path somewhere, only had it with an internationalized domain name. The warning it gave in the UI was "Warnung: The ticket has been created, but an error occurred while sending notifications: 'ascii' codec can't encode character u'\xe9' in position 22: ordinal not in range(128)" and the same message appeared in the log as an ERROR.

pacopablo's patch, which fixes the issue

[John Hampton]

So, the issue is that we use the project url as part of the Message-ID hash. If it has non-ascii characters in it, then it fails during `md5().hexdigest()'.

The solution is to simply encode the project url in ascii, ignoring any non-convertible characters. I'll create a test and then commit the fix.

Convert project url to UTF-8 when being used in the message-id

[John Hampton]

The attached patch​ takes a slightly different approach in that it converts the project url to UTF-8, instead of dropping unconvertible characters converting to ASCII.

The accompanying test verifies the change.

Raphael, will you please try the attached patch and post the outcome?

John, thanks for the patch! I've applied it and it works as expected.

In testing it, however, I noticed I still had smtp_default_domain and smtp_from set to the "xn—…" transcriptions of the domain name. Using Unicode chars in there reveals another error message, "Warnung: The change has been saved, but an error occurred while sending notifications: execv() arg 2 must contain only strings".

Fixed in [9267].

Raphael, I am closing this ticket as this issue is now fixed. I have opened ticket #9082 to track the issue with smtp_default_domain and smtp_from. Will you please add yourself to the CC list for #9082, as well as post a traceback there? Thanks
