# Shell library to run git-daemon in tests. Ends the test early if

# start_git_daemon

tests: turn on network daemon tests by default We do not run the httpd nor git-daemon tests by default, as they are rather heavyweight and require network access (albeit over localhost). However, it would be nice if more pepole ran them, for two reasons: 1. We would get more test coverage on more systems. 2. The point of the test suite is to find regressions. It is very easy to change some of the underlying code and break the httpd code without realizing you are even affecting it. Running the httpd tests helps find these problems sooner (ideally before the patches even hit the list). We still want to leave an "out", though, for people who really do not want to run them. For that reason, the GIT_TEST_HTTPD and GIT_TEST_GIT_DAEMON variables are now tri-state booleans (true/false/auto), so you can say GIT_TEST_HTTPD=false to turn the tests back off. To support those who want a stable single way to disable these tests across versions of Git before and after this change, an empty string explicitly set to these variables is also taken as "false", so the behaviour changes only for those who: a. did not express any preference by leaving these variables unset. They did not test these features before, but now they do; or b. did express that they want to test these features by setting GIT_TEST_FEATURE=false (or any equivalent other ways to tell "false" to Git, e.g. "0"), which has been a valid but funny way to say that they do want to test the feature only because we used to interpret any non-empty string to mean "yes please test". They no longer test that feature. In addition, we are forgiving of common setup failures (e.g., you do not have apache installed, or have an old version) when the tri-state is "auto" (or unset), but report an error when it is "true". This makes "auto" a sane default, as we should not cause failures on setups where the tests cannot run. But it allows people who use "true" to catch regressions in their system (e.g., they uninstalled apache, but were expecting their automated test runs to test git-httpd, and would want to be notified).
