Bump golang 1.12.8 (CVE-2019-9512, CVE-2019-9514)

go1.12.8 (released 2019/08/13) includes security fixes to the net/http and net/url packages.
See the Go 1.12.8 milestone on our issue tracker for details:

https://github.com/golang/go/issues?q=milestone%3AGo1.12.8

- net/http: Denial of Service vulnerabilities in the HTTP/2 implementation
  net/http and golang.org/x/net/http2 servers that accept direct connections from untrusted
  clients could be remotely made to allocate an unlimited amount of memory, until the program
  crashes. Servers will now close connections if the send queue accumulates too many control
  messages.
  The issues are CVE-2019-9512 and CVE-2019-9514, and Go issue golang.org/issue/33606.
  Thanks to Jonathan Looney from Netflix for discovering and reporting these issues.
  This is also fixed in version v0.0.0-20190813141303-74dc4d7220e7 of golang.org/x/net/http2.
  net/url: parsing validation issue
- url.Parse would accept URLs with malformed hosts, such that the Host field could have arbitrary
  suffixes that would appear in neither Hostname() nor Port(), allowing authorization bypasses
  in certain applications. Note that URLs with invalid, not numeric ports will now return an error
  from url.Parse.
  The issue is CVE-2019-14809 and Go issue golang.org/issue/29098.
  Thanks to Julian Hector and Nikolai Krein from Cure53, and Adi Cohen (adico.me) for discovering
  and reporting this issue.

Testing

This document contains the Moby code testing guidelines. It should answer any questions you may have as an aspiring Moby contributor.

Test suites

Moby has two test suites (and one legacy test suite):

Unit tests - use standard go test and gotest.tools/assert assertions. They are located in the package they test. Unit tests should be fast and test only their own package.
API integration tests - use standard go test and gotest.tools/assert assertions. They are located in ./integration/<component> directories, where component is: container, image, volume, etc. These tests perform HTTP requests to an API endpoint and check the HTTP response and daemon state after the call.

The legacy test suite integration-cli/ is deprecated. No new tests will be added to this suite. Any tests in this suite which require updates should be ported to either the unit test suite or the new API integration test suite.

Writing new tests

Most code changes will fall into one of the following categories.

Writing tests for new features

New code should be covered by unit tests. If the code is difficult to test with a unit tests then that is a good sign that it should be refactored to make it easier to reuse and maintain. Consider accepting unexported interfaces instead of structs so that fakes can be provided for dependencies.

If the new feature includes a completely new API endpoint then a new API integration test should be added to cover the success case of that endpoint.

If the new feature does not include a completely new API endpoint consider adding the new API fields to the existing test for that endpoint. A new integration test should not be added for every new API field or API error case. Error cases should be handled by unit tests.

Writing tests for bug fixes

Bugs fixes should include a unit test case which exercises the bug.

A bug fix may also include new assertions in an existing integration tests for the API endpoint.

Integration tests environment considerations

When adding new tests or modifying existing test under integration/, testing environment should be properly considered. skip.If from gotest.tools/skip can be used to make the test run conditionally. Full testing environment conditions can be found at environment.go

Here is a quick example. If the test needs to interact with a docker daemon on the same host, the following condition should be checked within the test code

skip.If(t, testEnv.IsRemoteDaemon())
// your integration test code

If a remote daemon is detected, the test will be skipped.

Running tests

Unit Tests

To run the unit test suite:

make test-unit

or hack/test/unit from inside a BINDDIR=. make shell container or properly configured environment.

The following environment variables may be used to run a subset of tests:

TESTDIRS - paths to directories to be tested, defaults to ./...
TESTFLAGS - flags passed to go test, to run tests which match a pattern use TESTFLAGS="-test.run TestNameOrPrefix"

Integration Tests

To run the integration test suite:

make test-integration

This make target runs both the "integration" suite and the "integration-cli" suite.

You can specify which integration test dirs to build and run by specifying the list of dirs in the TEST_INTEGRATION_DIR environment variable.

You can also explicitly skip either suite by setting (any value) in TEST_SKIP_INTEGRATION and/or TEST_SKIP_INTEGRATION_CLI environment variables.

Flags specific to each suite can be set in the TESTFLAGS_INTEGRATION and TESTFLAGS_INTEGRATION_CLI environment variables.

If all you want is to specity a test filter to run, you can set the TEST_FILTER environment variable. This ends up getting passed directly to go test -run (or go test -check-f, dpenending on the test suite). It will also automatically set the other above mentioned environment variables accordingly.

Go Version

You can change a version of golang used for building stuff that is being tested by setting GO_VERSION variable, for example:

make GO_VERSION=1.12.8 test
