Plain text email includes line endings

[jared.bownds@…]

For some reason, our production instance of trac sends plain text emails with line endings IN the email itself. Our development instance (which matches our production instance) does not experience the same issue. Can anyone advise what the problem may be?

Example Email:

We experienced the issue on trac-hacks.org: ​th:#11159. The issue is seen with Genshi 0.7 (​genshi:#569), and the resolution is to downgrade to Genshi 0.6.1, until Genshi 0.7.1 is released.

[Ryan J Ollos]

According to ​genshi:comment:11:ticket:569 and ​[genshi 1256], changing your line endings from \r\n to \n might also fix the issue, but I haven't tried. I did confirm that ticket-notify-email on trac-hacks.org has CRLF line endings:

file lib/python2.6/site-packages/Trac-1.0.1-py2.6.egg/trac/ticket/templates/ticket_notify_email.txt 
lib/python2.6/site-packages/Trac-1.0.1-py2.6.egg/trac/ticket/templates/ticket_notify_email.txt: ASCII text, with CRLF line terminator

The eol-style in the repository is native: tags/trac-1.0.1/trac/ticket/templates/ticket_notify_email.txt​, so when checking out the repository on Linux I get:

$ file trac/ticket/templates/ticket_notify_email.txt 
trac/ticket/templates/ticket_notify_email.txt: ASCII text

However, if make a virtualenv and run easy_install trac==1.0.1, I get a ticket_notify_email.txt with CRLF line endings:

$ file lib/python2.7/site-packages/Trac-1.0.1-py2.7.egg/trac/ticket/templates/ticket_notify_email.txt 
lib/python2.7/site-packages/Trac-1.0.1-py2.7.egg/trac/ticket/templates/ticket_notify_email.txt: ASCII text, with CRLF line terminators

Maybe the issue would be fixed if you changed your line endings to LF using dos2unix?

[Ryan J Ollos]

Following some additional testing, an FAQ has been adding: TracFaq#Q:Whydoticketnotificationemailscontainunexpectedbackslashcharacters

I reproduced the issue on Ubuntu as follows. After installing from PyPI using easy_install,

$ easy_install trac==1.0.1
Searching for trac==1.0.1
Reading http://pypi.python.org/simple/trac/
Reading http://projects.edgewall.com/trac
Reading http://projects.edgewall.com/trac/wiki/TracDownload
Reading http://trac.edgewall.com/
Best match: Trac 1.0.1
Downloading https://pypi.python.org/packages/source/T/Trac/Trac-1.0.1.zip#md5=7a2577262fa6dd8bf3136d8377130a90

the backslashes were seen in the email notification, and it was confirmed again that the template has CRLF line endings:

$ file lib/python2.7/site-packages/Trac-1.0.1-py2.7.egg/trac/ticket/templates/ticket_notify_email.txt 
lib/python2.7/site-packages/Trac-1.0.1-py2.7.egg/trac/ticket/templates/ticket_notify_email.txt: ASCII text, with CRLF line terminators

The issue was fixed with:

$ dos2unix lib/python2.7/site-packages/Trac-1.0.1-py2.7.egg/trac/ticket/templates/ticket_notify_email.txt 
dos2unix: converting file lib/python2.7/site-packages/Trac-1.0.1-py2.7.egg/trac/ticket/templates/ticket_notify_email.txt to Unix format ...

I'm guessing that the package was prepared on Windows, and therefore template in the package has CRLF line endings since svn:eol-style is native.

I can think of two workarounds for Trac 1.0.2 since we still need to support Genshi 0.7:

1. Manually change the line endings to LF when preparing the package for release, if necessary for the platform on which the release is prepared.
2. Change svn:eol-style of branches/1.0-stable/trac/ticket/templates/ticket_notify_email.txt​ to LF.
