[new-run-webkit-tests][Chromium] split http_server into a new top level script plus a module

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Dirk Pranke]

Chromium's ui_test infrastructure uses the layout tests http_server infrastructure for some HTTP testing. At the moment it calls into webkitpy/layout_tests/port/http_server directly (as a __main__), but this is awkward, buggy on a mac, and has several layering violations.

I'm going to resolve this by creating a new top-level new-run-webkit-httpd script and call that instead, and make http_server just be a module.

The new script only works w/ Chromium's LigHTTP implementation, but should be made generic.

LGTM, but I thought that Ojan had already made up a python version of run-webkit-httpd which knew how to talk to apache2?

I'm ready to r+ this as soon as we hear from Ojan.

Or rather, I'll r+ it, but I'd like Ojan to bless the patch before landing. :)

If he does, I haven't seen it. However, the chromium test code actually has switches hard-coded into it for the LigHTTPd version (unfortunately), so I would like to address the whole apache/lighttpd thing separately from this patch.

A couple nits on comments. The code looks fine. No need for another review before committing though.

Could you file a bug for this and link to it in the ChangeLog description?

I don't think this needs to be documented. It's not an explicit goal of the WebKit project to support Chromium's ui_test infrastructure. I don't think it's an issue in practice, but if WebKit needed this to change in a way that's incompatible with Chromium's needs, then it should be able to.

Done. See bug 35820.

Grr. I thought FIXME was Chromium and TODO was WebKit. Guess I got it backwards.

I agree that WebKit should be able to change things, but it doesn't hurt to have the dependency documented.
