#2281 closed defect (fixed)

Failed Installation; Syntax Error

Reported by: sean.wedig@… Owned by: Russ Tyndall
Priority: normal Component: TimingAndEstimationPlugin
Severity: normal Keywords: installation failure
Cc: Trac Release: 0.11


This may be related to #2270, but my symptoms weren't exactly the same, so I'm creating a new ticket. For reference, my setup:

The virtual python 2.3 is because I am on a shared host, and do not have access to update python or install packages.

Anyway, my installation is failing as well. I'm attempting to install via easy_install, as follows:

> easy_install


Doing subversion checkout from to /tmp/easy_install-a07N9v/trac0.11
Processing trac0.11
Running -q bdist_egg --dist-dir /tmp/easy_install-a07N9v/trac0.11/egg-dist-tmp-KlCluM
  File "build/bdist.linux-i686/egg/timingandestimationplugin/", line 15
    self.billing_reports = set(x[0] for x in cur.fetchall())
SyntaxError: invalid syntax
zip_safe flag not set; analyzing archive contents...
Adding timingandestimationplugin 0.5.7 to easy-install.pth file

Installed /home/[user]/lib/python2.3/site-packages/timingandestimationplugin-0.5.7-py2.3.egg
Processing dependencies for timingandestimationplugin==0.5.7
Finished processing dependencies for timingandestimationplugin==0.5.7

Attempting to do other things with the plugin, such as upgrading the Trac environment, fail with similar syntax errors.

I'm unsure if this is related to Python 2.3, or if it's just the code base. Please let me know if you need other additional information, and I'll do my best to help.

I installed a local Python 2.5, and went back to re-install everything else. It appears to be the fact that the host is using an old version of Python, and I'm not receiving the syntax error (though I'm not fully installed yet).

However, technically, this is a valid version of Python for Trac 0.11 dev (see:, so this may still be considered a bug.

Resolution: fixed
Status: newclosed

Just FYI we use generator expressions which were only added in python 2.4. Since you seem to have worked around it already, I will close this ticket. Given that python 3000 is in beta, 2.3 is already 2 versions old working on 3. If it becomes a serious issue preventing you from using this, please reopen and I will try to work around this by not using generator expressions.
