repo is humongous

[sneakers-the-rat]

related to #36

#36 talks about adding test outputs to .gitignore, which looks like has already been done.

however the test outputs are still in the repo history, and so the repo is 700MB

If i list the objects in the git repo by size

git rev-list --objects --all | \
  git cat-file --batch-check='%(objectname) %(objecttype) %(objectsize) %(rest)' | \
  sort -nr -k 3 | \
  perl -ne 'm#^(\w+) blob (\d+) (.+)# or next; print "$1\t$2\t$3\n";' | \
  head -n 200 | \
  column -t -s $'\t'

then i get a big list like...

...

and so on.

the tests/output directory is still full of data, even though it's ignored with .gitignore, so need to do two things:

• remove currently tracked files from tests/output
• purge git history with git filter-repo

(this should be done after all the outstanding branches are merged, since it will likely result in them being orphaned since filter-repo involved force rewriting git history)
