From 8f2146dbf15566fa60787a3261a048e4d5116d6a Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 23 Feb 2023 06:08:41 -0500 Subject: [PATCH] t5559: make SSL/TLS the default The point of t5559 is run the regular t5551 tests with HTTP/2. But it does so with the "h2c" protocol, which uses cleartext upgrades from HTTP/1.1 to HTTP/2 (rather than learning about HTTP/2 support during the TLS negotiation). This has a few problems: - it's not very indicative of the real world. In practice, most servers that support HTTP/2 will also support TLS. - support for upgrading does not seem as robust. In particular, we've run into bugs in some versions of Apache's mod_http2 that trigger only with the upgrade mode. See: https://lore.kernel.org/git/Y8ztIqYgVCPILJlO@coredump.intra.peff.net/ So the upside is that this change makes our HTTP/2 tests more robust and more realistic. The downside is that if we can't set up SSL for any reason, we'll skip the tests (even though you _might_ have been able to run the HTTP/2 tests the old way). We could probably have a conditional fallback, but it would be complicated for little gain, and it's not even clear it would help (i.e., would any test environment even have HTTP/2 but not SSL support?).
