Open Stack

Ken, can you clarify what you did?  I have the same issue in my local dev environment for barbican.

I had keystonemidleware 1.6.1, pbr 1.1.1

After the update to requirements.txt I get the same failure: ValueError: ("Expected ',' or end-of-list in", "python-ldap>=2.4;python_version=='2.7'", 'at', ";python_version=='2.7'")

I deleted my .tox, .testrepository, still had the problem.  Then I found your email.

I updated keystonemiddleware to 2.0.0 (which brought along pbr 1.2.0) but the problem still exists.

Simply running tox gives me the problem for all of our targets.

Thanks!

I found the issue. It is because my keystonemiddleware version is 1.6.1, while this version require pbr<1.0, >=0.6 (for keystonemiddleware>=1.5.0). So in the devstack installation, it will downgrade my pbr from 1.2.0 to 0.11.0.
After I upgrade my keystonemiddleware to 2.0.0 and pbr back to 1.2.0, this issue does not exist now. Therefore it is a bug, for pbr-0.11.0 is not compatible with those projects with lines like "*;python_version=='2.7'", while in their requirements.txt files there are still "pbr<2.0,>=0.11".

Subject: [devstack][keystone][nova][glance][heat] error met when dealing with requirements files

Today when I tried to build devstack on Ubuntu trusty, I found errors that I have not met before:

error in setup command: 'tests_require' must be a string or list of strings containing valid project/version requirement specifiers; Expected ',' or end-of-list in python-ldap>=2.4;python_version=='2.7' at ;python_version=='2.7'

It is because in keystone/test_requirements.txt, there is a line which cannot be recognized (the part after the semicolon):

python-ldap>=2.4;python_version=='2.7'

There are similar issue in glance/test_requirements.txt, nova/test_requirements.txt, and heat/requirements.txt where we have line like "*;python_version=='2.7'"
I do not know why, for I have already upgraded my pip and setuptools to the latest version.
