Fun with Travis

Describes experiments with using Travis.

How does Travis handle cache files?

To answer this, set up a travis file with cache and add cat $0 to the script proof.

You'll see that:

• Travis fetches and uploads the cache files from Google storage https://travis-cache-production-org-gce.storage.googleapis.com where the bucket id is the Travis repo id and Travis publick key is GOOGZFGMULTAVLI3C63H, eg the cache url is https://travis-cache-production-org-gce.storage.googleapis.com/105377138/test/cache--linux-xenial-e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855--rvm-default--gemfile-Gemfile.tgz?Expires=1582393178&GoogleAccessId=GOOGZFGMULTAVLI3C63H&Signature=oSFR4uHZqTicXNT40ovlARQQuFs
• The URL requires the three parameters Expires, GoogleAccessId and Signature (documentation)
• When a cache is needed in subsequent builds, Travis re-generates a new URL with a good signature and new expiration time based on their secret
• conclusion: it is possible to access the cache from outside Travis by reading the url at cache\ push but not beyond the expiration date
• travis uses a tool called casher available at https://github.com/travis-ci/casher and downloaded from https://build.travis-ci.org/files/casher
• See also https://docs.travis-ci.com/user/caching/

How to push to github directly from Travis?

For a single file, one way is to call the travis API as follows (with the environment variable GITHUB_AUTH_TOKEN set). Don't push to the same branch directly or this trigger an infinite recursion of travis calls.

script:
- curl -O https://raw.githubusercontent.com/monperrus/misc/master/push-file-to-github.sh
- chmod 755 push-file-to-github.sh
- echo foo bar > foo.txt
- ./push-file-to-github.sh foo.txt monperrus fun-with-travis data2

Proof: build log commit from travis

How to enrich the travis build with content from elsewhere?

It is possible to get the travis script from another source than the repo itself. For example, in .travis.yml

install:
- curl -o build.sh http://www.monperrus.net/martin/build.txt
- chmod 755 build.sh

script:
- ./build.sh

proof

How to trigger another build from Travis?

Now let's add trigger a Travis build from a travis build.

body='{
"request": {
"branch":"'$TARGET_BRANCH'"
}}'

# requires before "gem install travis"
travis login --github-token $GITHUB_AUTH_TOKEN
TRAVIS_TOKEN=$(travis token --no-interactive)

curl -s -X POST \
   -H "Content-Type: application/json" \
   -H "Accept: application/json" \
   -H "Travis-API-Version: 3" \
   -H "Authorization: token "$TRAVIS_TOKEN \
   -d "$body" \
   https://api.travis-ci.org/repo/$TARGET_REPO/requests

proof

How to delete a Github branch from Travis?

It is quite easy to delete a branch from travis

curl -X DELETE -H Authorization:\ token\ $GITHUB_AUTH_TOKEN https://api.github.com/repos/monperrus/travis/git/refs/heads/branchname

Interestingly, it is possible to do an autodestructing branch, where the built deletes the branch from which it is being built, by using environment variable $TRAVIS_BRANCH:

curl -X DELETE -H Authorization:\ token\ $GITHUB_AUTH_TOKEN https://api.github.com/repos/monperrus/travis/git/refs/heads/$TRAVIS_BRANCH

proof

Note that is impossible to delete branch "master" (which is protected by default, unless changed).

Removing the branch makes it harder to reproduce the build, but if one outputs enough information in the build trace, that's still possible.

How to install Github's Hub on travis?

No solution yet

# does not work
go get github.com/github/hub
error:
package github.com/github/hub: no buildable Go source files in /home/travis/gopath/src/github.com/github/hub

How to add an environment variable to travis?

$ travis encrypt SOMETHING=foobar
Detected repository as monperrus/travis, is this correct? |yes| 
Please add the following to your .travis.yml file:

  secure: "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"

Pro Tip: You can add it automatically by running with --add.

# --add must be at the end
$ travis encrypt SOMETHING=foobar --add 

How to install "travis" (the tool) and "travis" (the environment)

Simply "gem install travis" (proof)

If a key is available, one can register a Travis session on travis.

travis login --github-token $GITHUB_AUTH_TOKEN

And create a travis token

travis token --no-interactive
