.git folder is huge

[czosel]

I got a timeout when I was trying to install PHPWord with composer. It seems that the .git folder is huge:

$ du -h --max-depth=1
2.1M	./src
1.9M	./tests
144K	./docs
1.2M	./samples
336M	./.git

Can someone tell how this happened, and if there would be a chance to do some history-rewriting to slim the .git folder down?

If you like, this could also be considered a composer issue (see composer/composer#3449).

git gc is run automatically on remote git repos, so that doesn't help. This answer on SO shows how to find the largest files in a git repo, which returns something like this in our case (listing only some of the biggest files):

It seems that the massive .git folder is essentially filled with old coverage reports. I'd suggest running some filter-branch magic to get rid of them, what do you think @troosan?

[czosel]

Oh, looking at where those files are coming from reveals that this is a CI issue:

commit 04192091191069e2692f52f8b9eb5449da2ce5cc
Author: travis-ci <travis@travis-ci.org>
Date:   Wed Apr 18 07:11:36 2018 +0000

    PHPDocumentor (Travis Build: 1695  - Branch: develop)

PHPWord/.travis_shell_after_success.sh

Line 30 in c52c96d

cp -Rf $HOME/coverage-latest/* ./coverage/$TRAVIS_BRANCH/

I'm not sure what the motivation is behind this? Maybe uploading the coverage could just be removed?

[troosan]

Indeed, I don't think there is much added value in keeping those code coverage reports and phpDocumentation.
Maybe we could track code coverage with https://github.com/marketplace/coveralls?
What do you think @Progi1984, does anybody check the content of the gh-pages anyway?

[czosel]

I didn't even find the gh-pages, are they supposed to be here?
http://phpoffice.github.io/PHPWord/docs/master/

[troosan]

The github pages were dropped a couple of months ago

[Progi1984]

@troosan I agree to delete gh-pages and migrate to coveralls. I think doing the same thing for PHPPresentation.

[czosel]

@Progi1984 Awesome! I updated #1360 to include coveralls integration.
