Support for using travis-ci has been added in order to automate pull-testing.
|
||
|
|
See https://travis-ci.org/ for more info
|
||
|
|
|
||
|
|
This procedure is different than the pull-tester that came before it in a few
|
||
|
|
ways.
|
||
|
|
|
||
|
|
There is nothing to administer. This is a major feature as it means
|
||
|
|
that builds have no local state. Because there is no ability to login to the
|
||
|
|
builders to install packages (tools, dependencies, etc), the entire build
|
||
|
|
procedure must instead be controlled by a declarative script (.travis.yml).
|
||
|
|
This script declares each build configuration, creates virtual machines as
|
||
|
|
necessary, builds, then discards the virtual machines.
|
||
|
|
|
||
|
|
A build matrix is constructed to test a wide range of configurations, rather
|
||
|
|
than a single pass/fail. This helps to catch build failures and logic errors
|
||
|
|
that present on platforms other than the ones the author has tested. This
|
||
|
|
matrix is defined in the build script and can be changed at any time.
|
||
|
|
|
||
|
|
All builders use the dependency-generator in the depends dir, rather than
|
||
|
|
using apt-get to install build dependencies. This guarantees that the tester
|
||
|
|
is using the same versions as Gitian, so the build results are nearly identical
|
||
|
|
to what would be found in a final release. However, this also means that builds
|
||
|
|
will fail if new dependencies are introduced without being added to the
|
||
|
|
dependency generator.
|
||
|
|
|
||
|
|
In order to avoid rebuilding all dependencies for each build, the binaries are
|
||
|
|
cached and re-used when possible. Changes in the dependency-generator will
|
||
|
|
trigger cache-invalidation and rebuilds as necessary.
|
||
|
|
|
||
|
|
These caches can be manually removed if necessary. This is one of the the very few
|
||
|
|
manual operations that is possible with Travis, and it can be done by the
|
||
|
|
Bitcoin Core committer via the Travis web interface.
|
||
|
|
|
||

|
In some cases, secure strings may be needed for hiding sensitive info such as
|
||
|
|
private keys or URLs. The travis client may be used to create these strings:
