Description:
The latest bout of pacman -Su results in updating dependencies for buildbot. However, buildbot cannot work at all with the version of sqlalchemy-migrate currently provided. Trying to do even the most basic of buildbot actions results in this: Traceback (most recent call last): File "/usr/bin/buildbot", line 4, in <module> runner.run() File "/usr/lib/python2.7/site-packages/buildbot/scripts/runner.py", line 730, in run subcommandFunction = reflect.namedObject(subconfig.subcommandFunction) File "/usr/lib/python2.7/site-packages/twisted/python/_reflectpy3.py", line 151, in namedObject module = namedModule('.'.join(classSplit[:-1])) File "/usr/lib/python2.7/site-packages/twisted/python/_reflectpy3.py", line 137, in namedModule topLevel = __import__(name) File "/usr/lib/python2.7/site-packages/buildbot/scripts/upgrade_master.py", line 25, in <module> from buildbot.db import connector File "/usr/lib/python2.7/site-packages/buildbot/db/connector.py", line 22, in <module> from buildbot.db import pool, model, changes, schedulers, sourcestamps, sourcestampsets File "/usr/lib/python2.7/site-packages/buildbot/db/model.py", line 17, in <module> import migrate File "/usr/lib/python2.7/site-packages/migrate/__init__.py", line 9, in <module> from migrate.changeset import * File "/usr/lib/python2.7/site-packages/migrate/changeset/__init__.py", line 21, in <module> from migrate.changeset.schema import * File "/usr/lib/python2.7/site-packages/migrate/changeset/schema.py", line 15, in <module> from migrate.changeset.databases.visitor import (get_engine_visitor, File "/usr/lib/python2.7/site-packages/migrate/changeset/databases/visitor.py", line 6, in <module> from migrate.changeset import ansisql File "/usr/lib/python2.7/site-packages/migrate/changeset/ansisql.py", line 10, in <module> from sqlalchemy.schema import SchemaVisitor ImportError: cannot import name SchemaVisitor |

Buildbot requires sqlalchemy between 0.6 and 0.7.10 (they've since released 0.7.11 too, which works), and one of the listed versions of sqlalchemy-migrate:
'sqlalchemy-migrate ==0.6.1, ==0.7.0, ==0.7.1, ==0.7.2'
The issue is an incompatibility between sqlalchemy-migrate and sqlalchemy.
Is it solve the problem if you downgrade python2-sqlalchemy package to version 0.8.4-1? You can download it from here:
http://seblu.net/a/arm/2013/12/31/community/os/x86_64/python2-sqlalchemy-0.8.4-1-x86_64.pkg.tar.xz
In this case please report the problem to the upstream maintainers of sqlalchemy-migrate:
https://code.google.com/p/sqlalchemy-migrate/issues/list
>That I fixed by editing /usr/lib/python2.7/site-packages/migrate/changeset/ansisql.py to change the following line:
>from sqlalchemy.schema import SchemaVisitor
>by:
>from sqlalchemy.sql.base import SchemaVisitor
