- add appveyor.yml
- path fixes for windows, use os.path.join
- templates_dir: use '/' always for jinja2 paths
- auto colls: ensure chdir before deleting dir
- recorder: ensure warc writer is always closed
- recorder: disable locking in warcwriter on windows for now (read access not avail, shared
lock seems to not be working)
- zipnum: ensure block is closed after read!
- cached dir test: wait before adding file
- tests: adjust timeout tests to allow more leeway in timing
setup.py just loads from requirements.txt
Dockerfile pip installs requirements, then extra requirements for improved cacheing
travis runs setup install, then installs extra requirements
