We have occasionally seen bugs that affect Git running only against an HTTP/2 web server, not an HTTP one. For instance,b66c77a64e(http: match headers case-insensitively when redacting, 2021-09-22). But since we have no test coverage using HTTP/2, we only uncover these bugs in the wild. That commit gives a recipe for converting our Apache setup to support HTTP/2, but: - it's not necessarily portable - we don't want to just test HTTP/2; we really want to do a variety of basic tests for _both_ protocols This patch handles both problems by running a duplicate of t5551 (labeled as t5559 here) with an alternate-universe setup that enables HTTP/2. So we'll continue to run t5551 as before, but run the same battery of tests again with HTTP/2. If HTTP/2 isn't supported on a given platform, then t5559 should bail during the webserver setup, and gracefully skip all tests (unless GIT_TEST_HTTPD has been changed from "auto" to "yes", where the point is to complain when webserver setup fails). In theory other http-related test scripts could benefit from the same duplication, but doing t5551 should give us a reasonable check of basic functionality, and would have caught both bugs we've seen in the wild with HTTP/2. A few notes on the implementation: - a script enables the server side config by calling enable_http2 before starting the webserver. This avoids even trying to load any HTTP/2 config for t5551 (which is what lets it keep working with regular HTTP even on systems that don't support it). This also sets a prereq which can be used by individual tests. - As discussed inb66c77a64e, the http2 module isn't compatible with the "prefork" mpm, so we need to pick something else. I chose "event" here, which works on my Debian system, but it's possible there are platforms which would prefer something else. We can adjust that later if somebody finds such a platform. - The test "large fetch-pack requests can be sent using chunked encoding" makes sure we use a chunked transfer-encoding by looking for that header in the trace. But since HTTP/2 has its own streaming mechanisms, we won't find such a header. We could skip the test entirely by marking it with !HTTP2. But there's some value in making sure that the fetch itself succeeded. So instead, we'll confirm that either we're using HTTP2 _or_ we saw the expected chunked header. - the redaction tests fail under HTTP/2 with recent versions of curl. This is a bug! I've marked them with !HTTP2 here to skip them under t5559 for the moment. Using test_expect_failure would be more appropriate, but would require a bunch of boilerplate. Since we'll be fixing them momentarily, let's just skip them for now to keep the test suite bisectable, and we can re-enable them in the commit that fixes the bug. - one alternative layout would be to push most of t5551 into a lib-t5551.sh script, then source it from both t5551 and t5559. Keeping t5551 intact seemed a little simpler, as its one less level of indirection for people fixing bugs/regressions in the non-HTTP/2 tests.
