Improved the travis-job test script so that it works outside of Travis.
This can be useful to test changes to the docker container config before
pushing to master, for testing changes on a branch, or for debugging
some problem with the tests running on Travis. This required the
following changes:
-The script no longer requires the TRAVIS env. variable to be set.
-Added an "all" command as a more convenient way to run all steps in a
build.
-Added a "coverity" command-line option to do a coverity build.
-Before building Bro or downloading coverity tools, do a cleanup from any
previous build.
Also other minor improvements (code comments, reorganization, etc.).
The advantage of using docker containers is to build and test Bro in
an environment that more closely resembles the environment where Bro
will actually be used. The docker containers currently used enable
testing Bro with all the major versions of gcc (versions 4 through 8),
as well as both python 2 and 3.
The "travis-job" script now takes a second parameter which specifies
a Linux distro to use (specifying "travis" will build and test bro
without using docker).
Improved readability of the output by adding more error checking
and better error and informational messages, and by moving the
unit test diag.log output to just before any external tests are run.
For pull request builds, skip the private tests instead of failing.
Prevent timeouts after 10 minutes of no output by not using the
btest "-b" option.
Decrease build time by not building unneeded components.
On Travis CI, btest was using 32 threads when running with "-j". Reducing
this to "-j 4" seems to make the tests run a bit faster overall and
somewhat reduces the number of test failures.
Remove some output from the Travis CI build log to make it easier
to read.
There is an issue with Travis CI when using encrypted environment
variables. In this case, when btest calls the python function
sys.stdout.isatty() it returns False, which causes btest to output one
line for each test (passed or failed). As a result, it is difficult to
see at a glance which tests failed. Switching to btest brief output to
address this issue.
I've moved .travis.job to testing/scripts/travis-job and adapted
.travis.yml accordingly.
